Description

The invention relates to a conductor terminal with an insulating housing, wherein the conductor terminal is designed as a multi-pole conductor terminal with several spring-loaded clamping connections arranged in the insulating housing, wherein the insulating housing has a conductor entry opening associated with each spring-loaded clamping connection, through which an electrical conductor can be inserted into the insulating housing in a conductor entry direction and clamped to the associated spring-loaded clamping connection by means of spring force, wherein a spring-loaded clamping connection has at least one busbar and a clamping spring, which has a clamping leg with a clamping edge for clamping an electrical conductor at a clamping point on a contact section of the busbar, wherein the conductor terminal has at least one actuating element by which, when a manual actuating section of the actuating element is actuated, the clamping leg can be moved into an open position.

Such a conductor terminal block is made from the DE 10 2020 119 372 A1 This is a conductor terminal with automatic connection of the electrical conductor to be connected when it is inserted into the terminal. Inserting the conductor automatically releases the clamping arm of the spring, which is held in an open position, thus clamping the conductor securely.

Based on this, the object of the present invention is to provide a further improved conductor terminal.

This problem is solved by arranging at least one actuating element between two adjacent conductor entry openings. This allows the actuating element to be integrated into the conductor terminal in a very space-saving manner. In particular, this makes it possible to easily and without a complete redesign of existing and proven conductor terminal designs that were previously manufactured without an actuating element, transforming them into conductor terminals with an actuating element for actuating the clamping arm.

The invention is suitable, for example, for compact junction box terminals, e.g., those with leaf spring connection, in which the clamping leg is connected to a support section of the clamping spring without a spring arc known in many conductor connection terminals, which extends over an angle range of more than 180°.

According to an advantageous embodiment of the invention, the at least one actuating element is designed as a pivotable lever, by which the clamping arm can be moved into the open position by means of a pivoting movement, or as a sliding push button, by which the clamping arm can be moved into the open position by means of a sliding movement. This allows for a wide range of possible realizations and integration options for the actuating element into an existing conductor terminal assembly. If the conductor terminal has several actuating elements, these can be uniformly designed as pivotable levers or sliding push buttons. It is also possible for the actuating elements to be designed differently, e.g., partly as levers and partly as push buttons.

The insulating housing can have a partition made of the same material between two adjacent conductor entry openings. This partition can extend into the interior of the insulating housing as far as the spring-loaded terminals to separate them, ensuring that an electrical conductor inserted through an entry opening can only be connected to the spring-loaded terminal associated with that entry opening. If such a partition is present, the actuating element can extend parallel to it. For example, the actuating element can be located directly on or abutting the partition.

According to an advantageous embodiment of the invention, the at least one actuating element arranged between the adjacent conductor entry openings simultaneously forms a partition between these openings. This further optimizes space savings, as the previously described partition of the insulating housing can be completely or at least partially omitted. The partition is then replaced by the actuating element arranged between the adjacent conductor entry openings. The actuating element can be made of an insulating material, for example, the same material as the insulating housing or another material, particularly a plastic.

According to an advantageous embodiment of the invention, it is provided that the at least one actuating element provides exactly one clamping force. which is actuated, or which allows the actuating element to actuate several clamping springs, in particular two adjacent clamping springs. The actuating element is advantageously arranged between two adjacent clamping springs. This also enables a multitude of possible configurations for the conductor terminal. If one actuating element is designed to actuate several clamping springs, fewer actuating elements are required in the conductor terminal, thus further reducing the space required. In this case, the insulating housing can, for example, have a partition between adjacent conductor entry openings where no actuating element is located.

According to an advantageous embodiment of the invention, the at least one actuating element is manually operable at its manual actuating section on a housing side of the insulating housing where the electrical conductor can be inserted into the respective conductor entry opening. Accordingly, the actuating element is advantageously manually operable on the conductor entry side of the insulating housing. If electrical conductors are already clamped at the terminals, the manual actuation of the actuating element is hindered by the parts of the electrical conductors protruding from the insulating housing, thereby reducing the likelihood of incorrect operation of the actuating element.

According to an advantageous embodiment of the invention, the manual actuation section is located between adjacent, connected electrical conductors when electrical conductors are connected to the conductor terminal. This also reduces the probability of incorrect actuation of the manual actuation element.

According to an advantageous embodiment of the invention, the conductor terminal has a retaining element designed to hold the clamping arm in the open position. This retaining element allows the clamping arm to remain in the open position even when no manual actuation force is applied to the actuating element. Such a design enables the integration of an automatic release technology into spring-loaded terminals and conductor terminals of various designs. In particular, proven conductor terminals of known design can thus be easily upgraded to include an automatic release function, i.e., with automatic connection of the electrical conductor to be clamped.

The retaining element can be movably arranged, e.g., sliding, pivoting, or otherwise deflectable, so that it can be easily deflected by the inserted conductor to achieve the desired release of the clamping arm from the retaining element. The retaining element can be slidably mounted, for example, in a linear or arc-shaped direction. The retaining element can be pivotally mounted. In this case, the retaining element can pivot about a fixed or variable pivot axis. In the case of a variable pivot axis, the retaining element can, for example, be mounted to pivot with a floating bearing. The retaining element can also perform a combined sliding and pivoting movement. The retaining element can also be movably mounted in another way so that it can deflect sufficiently far to release the locking of the clamping arm from the retaining element.

The actuating element allows the clamping arm to be moved into the open position by manual operation, against the spring force of the clamping spring. In this open position, the clamping arm can then be held by the retaining element, even without further manual operation of the actuating mechanism, so that the electrical conductor can be inserted at any time without requiring any special effort. For example, the clamping arm can be locked onto the retaining element in the open position.

The clamping arm, together with the contact section of the busbar, can form a clamping point for connecting an electrical conductor between the clamping arm and the contact section. In the open position, at least the clamping edge of the clamping arm is pivoted away from the contact section of the busbar. The clamping arm can be pivoted, for example, between an open position in which the electrical conductor is freely movable between the clamping arm and the contact section, and a clamped position in which the clamping arm clamps the electrical conductor to the contact section.

The retaining element can, for example, act directly on the clamping leg to hold it in the open position. Thus, for instance, a first locking element can be arranged on the clamping leg and a second locking element on the retaining element, with the first and second locking elements being able to interlock in the open position. The first locking element can be designed as a locking projection or locking hook. The second locking element can be designed as a locking edge or locking opening.

The retaining element can be a separate component, attached, for example, to the insulating housing of a conductor terminal block, to the busbar, or to another component. Alternatively, the retaining element can be integrally formed with the clamping spring.

According to an advantageous embodiment of the invention, the retaining element is arranged behind the clamping point or behind the majority of the busbar in the direction of conductor insertion into the spring-loaded clamping connection. In this way, the retaining element does not obstruct the insertion of the electrical conductor. For example, in the open position, i.e., when the clamping leg is locked onto the retaining element, the retaining element, when viewed in the direction of conductor insertion, may not protrude into a conductor receiving space, or may only protrude slightly, relative to the clamping leg.

According to an advantageous embodiment of the invention, the spring-loaded clamping connection has a release element, the actuation of which deflects the retaining element sufficiently to release the clamping leg held on the retaining element. The release element may have a release section. The clamping leg, held on the retaining element in the open position, can be released from the retaining element by the release element when an electrical conductor to be connected exerts an actuating force on the release section. This allows the clamping leg to be automatically released from the retaining element by inserting the electrical conductor. The release section can be actuated by a separate tool, a component of the conductor connection terminal (such as an actuating element), or directly by the inserted electrical conductor itself, thereby causing the clamping leg to be released from the retaining element. The release element allows the clamping leg, which is held in the open position on the retaining element, to be released from the retaining element by applying pressure to the release section in the conductor entry direction (L) of the electrical conductor to be connected. Depending on the design of the spring-clamp connection, the release element can be formed as part of the clamping spring, e.g., as a release element integrally formed with the clamping spring, or as a separate component.

According to an advantageous embodiment of the invention, the release element is integrated into the component or assembly of the spring-clamp connection that includes the retaining element. This minimizes the design and assembly effort for the spring-clamp connection. In particular, only one component or assembly is required for mounting the release element and the retaining element, rather than two separate components or assemblies. For example, the release element can be integrally formed with the retaining element. The component or assembly can be made of, for example, plastic or metal, or a combination of such materials.

According to an advantageous embodiment of the invention, the clamping spring has a support section designed to support the clamping spring on the busbar. This support section ensures secure support of the clamping spring and provides sufficient resistance to the spring force exerted by the clamping leg.

According to an advantageous embodiment of the invention, the support section comprises a base section and a mounting section, wherein the clamping leg branches off from the base section and the support section, with its mounting section, engages behind the busbar, so that the busbar rests on the mounting section and is at least partially arranged between the base section and the mounting section. The clamping leg can branch off from the base section, in particular without a 180° spring arc. For example, the clamping leg can branch off from the base section at an acute angle, which, for instance, may be less than 60° in the open position. The base section can be connected to the mounting section via a connecting section. For example, the base section can run substantially parallel to the mounting section or at a slight angle to it, in particular an angle of less than 20°.

According to an advantageous embodiment of the invention, a conductor guidance channel can be formed in the insulating housing for guiding the electrical conductor to be clamped to the contact section, wherein the release section of the release element is arranged in the conductor guidance channel or at least projects into the conductor guidance channel or is at least arranged in extension of the conductor entry channel.

According to an advantageous embodiment of the invention, the release section of the release element can be arranged behind the contact section or at least behind the clamping point in the conductor insertion direction.

For the purposes of the present invention, the indefinite term "a" is not to be understood as a numeral. Therefore, when, for example, reference is made to a component, this is to be interpreted as "at least one component". Angles are given in degrees. These measurements refer to a circular dimension of 360 degrees (360°).

The 1 and 2 Figure 1 shows a conductor terminal 1 which has an insulating housing 2. The insulating housing 2 has a conductor entry opening 20 on one conductor entry side, through which an electrical conductor can be inserted into the insulating housing 1 in a conductor entry direction L and clamped to a spring-loaded terminal.

A spring-loaded clamping connection is visible in the insulating housing 2, comprising a clamping spring 4 and a busbar 3. The clamping spring 4 has a support section 41, via which the clamping spring 4 is supported on the busbar 3. The clamping spring 4 also has a clamping leg 43 branching off from the support section 41 at an acute angle. The clamping leg 43 extends to a free end at which the clamping leg 43 has a 2 The visible clamping edge 46 is used to clamp the electrical conductor. In the 1 In the clamping position shown, the clamping leg 43 with the clamping edge 46 rests against a contact section 31 of the busbar 3 when no electrical conductor is inserted. An electrical conductor can be clamped between the clamping leg 43 or the clamping edge 46 and the contact section 31 at a clamping point 30.

The support section 41 extends from a base section 40, from which the clamping leg 43 branches off, to a connecting section 42 arranged at an angle to it. The connecting section 42 transitions into a fastening section 44 arranged at an angle to the connecting section 42. The fastening section 44 engages behind the busbar 3, i.e., it rests against the back of the busbar 3 on a side facing away from the clamping point 30.

The conductor terminal 1 also has a retaining element 5 by which the clamping leg 43 can be held in the open position. The retaining element 5 has a locking element 50 which can engage with a corresponding locking element on the clamping leg 43 in the open position. The clamping leg 43 cannot then easily move back into the clamped position. The locking element formed on the clamping leg 43 can, for example, be formed by the clamping edge 46, as illustrated in the figures. However, at least one separate locking element can also be formed on the clamping leg 43, for example, in the form of a projecting locking tab, which can then be engaged with the locking element 50.

To actuate the clamping leg 43 or to actuate several such clamping legs 43, e.g., a second adjacent clamping leg 43, the conductor terminal 1 has an actuating element 6 which is located in the 1 to 6 The illustrated embodiment is designed as a pivotable actuating lever. The actuating element 6 has a manual actuating section 60, at which the actuating element 6 can be manually actuated by a user, i.e., a pivoting movement of the actuating element 6 can be performed. For this purpose, the actuating element 6 is mounted on a bearing point 61 in the insulating housing 2. The actuating element 6 can be pivoted around the bearing point 61, as a comparison of the 1 and 3 shows.

The actuating element 6 extends with an actuating section 62 into the insulating housing 2 up to the clamping leg 43. 1 and show the clamping leg 43, which has not yet been deflected by the actuating element 6 and is in the clamping position in which the free end of the clamping leg can, for example, rest against the contact section 31 of the busbar 3. 3 The manual actuating element 6 was pivoted. This causes the clamping leg 43 to pivot away from the contact section 31 via the actuating section 62 until it engages with its clamping edge 46 or another detent element on the detent element 50 of the holding element 5 and is thereby held in the open position.

The 4 Figure 1 shows a perspective view of the conductor entry side of the insulating housing 2, which has two conductor entry openings 20. In this case, the conductor entry terminal 1 is designed as a two-pole terminal, but it can also be designed analogously as a multi-pole terminal with more than two spring-clamp connections. It is evident that the actuating element 6 is located between the conductor entry openings 20, specifically at a point where, in known conductor entry terminals, a partition wall of the insulating housing 2 is formed between the conductor entry openings 20. This partition wall can be omitted in the illustrated embodiment, as it can be replaced, at least to a large extent, by the actuating element 6, in particular the manual actuating section 60 and/or the part within the insulating housing adjoining the manual actuating section 60.

The 5 Figure 1 shows an advantageous design of the actuating element 6, which is designed as a pivotable actuating lever. Since the actuating element 6 is designed to actuate two adjacent clamping legs, the actuating section 62 can extend in the width direction beyond the otherwise relatively narrow design of the actuating element 6, so that the actuating element 6 can be hammer-shaped.

Based on the 6 This illustrates how a release element 8 can be integrated into the conductor terminal 1. The release element 8 serves to release the locking mechanism of the clamping leg 43 on the retaining element 5. The release element 8 has a release section 80, which can be actuated by the inserted electrical conductor. If an electrical conductor exerts a compressive force on the release section 80, the retaining element 5 with the locking element 50 is displaced slightly towards a rear housing wall 21 of the insulating housing 2 until the clamping leg 43 can release from the locking element 50. The clamping leg 43 then springs out until it rests against the inserted electrical conductor and presses it against the contact section 31.

The release element 8 can mechanically act on the retaining element 5 via a transmission section 81 when the release section 80 is actuated. This allows the retaining element 5, which can be rotatably suspended on a pivot bearing 55, to be rotated slightly, thereby releasing the locking mechanism between the locking element 50 and the clamping edge 46. The pivot bearing 55 can, for example, be a pin 47 projecting from the connecting section 42, as shown in the 11 The release element 8 can be designed, for example, as a rocker switch which engages in an opening 56 on the retaining element 5. The release element 8 can be designed, for example, as a rocker switch which can pivot when actuated at the release section 80.

The 7 to 11 Figure 1 shows an embodiment of a conductor terminal 1 with an actuating element 6 arranged between two adjacent conductor entry openings 20, which is designed as a sliding push button. The actuating element 6 in turn has a manual actuating section 60, which can be actuated by the user by pressing down on it from the conductor entry side. As a result of this pressure actuation, the actuating element 6 is moved further into the insulating housing 2, as shown in the figure. 8 This is illustrated. Through this sliding movement, the actuating element 6, by means of its actuating section 62, moves the clamping leg 43 from the in 7 shown clamping position in the 8 The open position shown shows the clamping leg 43 with its clamping edge 46 spaced away from the contact section 31. In the open position, the clamping leg 43 can again lock onto the detent element 50 by means of its clamping edge 46.

The 9 The conductor connection terminal 1 is shown in a comparable manner to the 4 , however, here with the actuating element 6 designed as a sliding push button.

As the 10 As shown, the actuating element 6 in the area of the actuating section 62 can also be used as the actuating element according to the 1 to 6 , be shaped like a hammer to deflect two adjacent clamping arms.

The 11 shows, similar to the 6 , the conductor connection terminal 1 with the release element 8, which is designed and functions in a comparable manner as shown in the 6 was explained.

The 12 Figure 4 shows an example of a clamping spring 4 in which two clamping legs 43 are implemented in a single unit. The clamping spring 4 is thus suitable for two adjacent spring-loaded clamping connections. The clamping spring 4 can be used with all previously described conductor connection terminals. The various sections of the support section 41 are visible, namely the base section 40, the connecting section 42, and the fastening section 44. Also visible are molded pins 47 on the connecting section 42, e.g., in the form of pins, which serve to receive and support the retaining element 5, as will be explained below.

The 13 Figure 3 shows a busbar 3 which offers two adjacent receiving points for electrical conductors at its contact section 31 and is therefore suitable for the in 12 The clamping spring 4 shown is suitable for realizing two adjacent spring-loaded clamping connections. Mounting brackets 34 for holding a retaining element 5 can be integrally formed on the busbar 3.

The 14 Figure 1 shows a combined retaining and releasing element 5, 8, which can be used as an alternative to the previously described conductor connection terminals 1. In contrast to embodiments in which the retaining element 5 and the releasing element 8 are separate components, here the retaining element 5 and the releasing element 8 are formed into a single unit, for example from sheet metal in the form of a stamped and bent part.

The holding-release element 5, 8 has a holding element 5 with two spaced-apart side plates 57 extending parallel to each other. Each side plate 57 has an opening 56 into which a corresponding pin 47 of the connecting section 42 can be inserted to form the pivot bearing 55. A locking element 50 is formed at the free end of each side plate 57. On the other side, the side plates 57 are connected to the release element 8 via lower longitudinal sections 53.

When force is applied to the release section 80 by the electrical conductor 9, the entire retaining-release element 5, 8 pivots around the pivot bearing 55. This causes the locking elements 50 to be displaced slightly backwards in the conductor insertion direction L, allowing the clamping leg 43 to release from them.

The 15 Figure 1 shows another embodiment of a combined holding-release element 5, 8, which can also be used as an alternative with the previously described conductor connection terminals 1. The holding-release element 5, 8 has a holding element 5 which is formed with the aforementioned locking element 50 at its free end.

The area of the retaining element 5 formed with the locking element 50 has positive-locking connecting elements 51 that can be inserted into the receiving elements 47 of the support section 41. This allows the locking element 50 to be supported against the spring force exerted by the clamping leg 43 in the open position on the support section 41, in particular on the connecting section 42. The retaining element 5 transitions via upper longitudinal sections 52 into the release element 8, on which the release section 80 is arranged. The release section 80 is connected on its opposite side via lower longitudinal sections 53 to a fastening section 54 of the retaining-release element 5, 8, which can be hooked into one of the brackets 34 on the busbar 3. This fixes the entire retaining-release element 5, 8 to the busbar 3.

When the release section 80 is subjected to force by the electrical conductor 9, the lower part of the retaining-release element 5, 8, which is attached to the bracket 34 via the fastening section 54, is fixed and cannot be deflected. Accordingly, only the upper part of the retaining-release element 5, 8 with the locking element 50 is deflected by the inserted electrical conductor 9 and the release section 80.

One can recognize in the 15 Furthermore, the combined retaining-release element 5, 8 in the area of the upper longitudinal sections 52 can be designed as a continuous sheet metal part, but can have a first recess 58 between the upper longitudinal sections 52. Similarly, the combined retaining-release element 5, 8 in the area of the lower longitudinal sections 53 can be designed as a continuous sheet metal part, but can have a second recess 59 between the lower longitudinal sections 53. The first and/or second recess 58, 59 increases the elasticity of the retaining-release element 5, 8, thereby reducing the required release forces that must be applied to the release section 80 by the inserted electrical conductor 9. Another advantage of the first and/or second recess 58, 59 is that a viewing window is provided through which it can be visually checked whether the electrical conductor 9 is inserted sufficiently far into the insulating housing 2, at least if a transparent housing material is used in this area.
