Description

The invention relates to an additional connector arrangement according to the preamble of claim 1, an additional connector of such an additional connector arrangement, an arrangement of such an additional connector arrangement and at least one or more connectable terminals and a method for removing an additional connector arrangement from such an arrangement.

In connection terminal arrangements comprising a plurality of connecting terminals arranged in a row, additional connecting plugs are often used as extensions, which have one or more conductor connections, in particular in direct plug-in technology (push-in), and / or are integrated or can be integrated into the electrical modules. Such additional connection plugs have a busbar part, by means of which they can be connected to a conductor connection of one of the connecting terminals arranged in a row. The conductor connections of the connected connection terminals often also have one or more conductor connections, which are designed using direct plug-in technology. The conductor connections then have a contact connection cage in which an electrical conductor or the busbar part of the additional connection plug can be clamped in an electrically contacting manner by means of a clamping spring.

The busbar part of the additional connector can be made of copper or a copper alloy. Depending on the clamping force of the clamping spring of the connection terminal, this may dig into such a busbar part of the inserted additional connector. The arrangement is then self-locking and the additional connecting plug can no longer be detached from the conductor connection of the connecting terminal by hand and / or without destruction.

In order to ensure the releasability of such a busbar part of an additional connector, the publication discloses EP 2 625 747 B1 to form or coat a clamping section of a busbar section of such an additional connector from a hard metal, namely steel. The clamping spring can then no longer dig into the busbar section, so that the arrangement is not designed to be self-locking. Then the additional connector can be pulled out of the connector without being destroyed and / or by hand.

However, it has been shown that such an additional connector plug with a non-self-locking busbar section can become loose, for example under vibration.

The object of the present invention is therefore to improve an additional connecting plug in such a way that, on the one hand, it can be released very easily from a connecting terminal, but, on the other hand, it cannot loosen or release itself under vibration.

The object is achieved with an additional connector arrangement with the features of independent claim 1, a first additional connector with the features of independent claim 12, an arrangement of an additional connector arrangement and one or more connection terminals with the features of independent claim 13 and a method for releasing an additional connector arrangement from the one or more connection terminals with the features of independent claim 15. Advantageous embodiments can be found in the dependent claims.

For this purpose, an additional connector arrangement is created with at least one first attachable additional connector, or with at least one first attachable additional connector and at least one second attachable additional connector. The additional connection plugs are each intended to be plugged into a conductor connection of an electrical connection terminal which is designed using direct plug-in technology.

They each have an additional housing in which at least one additional conductor connection is provided for connecting an electrical conductor. The additional conductor connection comprises an additional contact connection cage with a busbar. A busbar part of the busbar is guided outwards and is intended for insertion into the electrical connection terminal. The busbar part is not designed to be self-locking.

A non-self-locking busbar part in the sense of the invention is made of a harder metal than copper or is coated with such a metal. The metal is preferably a steel, in particular stainless steel. In the coated embodiment, the busbar part also comprises a layer of a highly conductive material such as copper or a copper alloy.

The additional connector arrangement is characterized in that the at least one first additional connector on the busbar part has a latching means for latching with a clamping spring of the conductor connection of the connecting terminal, and in the additional housing an adjustable actuating means for actuating a solvent for releasing the clamping spring of the conductor connection Terminal or an embodiment such that a separate actuating means can be guided through the additional housing to a solvent - for example a pusher of the clamping spring - or directly to the clamping spring of the conductor connection of the connecting terminal in order to release or open it.

The clamping spring, which is regularly provided in a direct connection technology for latching an inserted conductor, can latch when the first additional connector is plugged in with the latching means provided according to the invention on the busbar part, so that the additional connector is no longer detachable, in particular can be removed, manually or automatically from the conductor connection of the connector , This arrangement is then in a locked state. In the locked state, the electrical contact between the busbar part of the additional connector and the contact cage of the connection terminal is reliably guaranteed.

Even if the additional connecting plug arrangement comprises further additional connecting plugs of the second embodiment, which are arranged in line with the first additional connecting plug and do not have such a latching means on the busbar part, these cannot detach themselves automatically from the connecting terminal or several further connecting terminals connected to the connecting terminal due to the latching of the first additional connecting plug , and they cannot be solved by hand. An arrangement of an additional connecting plug arrangement comprising a plurality of additional connecting plugs and one or more connecting terminals is therefore also in the locked state.

However, due to their design, such additional connecting plugs often cover a solvent which is regularly provided in conductor connections in direct plug-in technology for opening the clamping spring, by the actuation of which a plugged-in conductor or the busbar part of the first additional connecting plug can be detached from the connecting terminal again. The adjustable actuating means provided according to the invention in the additional housing of the additional connecting plug enables the actuation of this solvent, so that the clamping spring of the conductor connection of the connecting terminal can be released from the latching means of the additional connecting plug. As a result, the first additional connecting plug can be removed from the connecting terminal, in particular by hand.

The connection terminal and the first additional connector plug inserted into it are in an unlocked state when the actuating means is actuated. Since the second additional connector (s) has no locking means for locking with the clamping spring of the connector into which they are inserted, and their busbar part is also not designed to be self-locking, they can also be pulled out of their connectors together with the first additional connector in the unlocked state. An arrangement of an additional connecting plug arrangement comprising a plurality of additional connecting plugs and one or more connecting terminals is therefore also in the unlocked state when the first additional connecting plug is unlocked.

For this purpose, the locking means is preferably designed as a locking lug or locking disc. However, it can also preferably be designed as a locking groove.

Furthermore, the actuating means is preferably arranged to be displaceable and / or rotatable in the additional housing. It is particularly preferably provided to be displaceable. It can be provided such that it can be operated by hand and / or by a tool, in particular a screwdriver.

If the additional connector arrangement has more than one first additional connector, in particular for securely latching it, it is preferred that the actuating means remains in the unlocked state. As a result, the actuating means of the plurality of first additional connecting plugs can be actuated one after the other, the already unlatched first additional connecting plugs remaining unlatched in order to detach the additional connecting plug arrangement from the arrangement of the plurality of connecting terminals arranged in a row.

For this purpose, the actuating means can be rotatably guided in a backdrop in the additional housing of the first additional connecting plug.

The actuating means can also be designed as a separate actuating means, for example as a screwdriver, which can be guided through the additional housing - for example an opening or a link or the like - to the clamping spring of the conductor connection of the connecting terminal in order to release or . to open.

In order to enable actuation of the solvent of the conductor connection of the connection terminal, it is also preferred that an open actuation end of the actuation means is guided outwards from the additional housing in the actuated state.

The actuating means for this purpose is very particularly preferably arranged in alignment with the solvent of the conductor connection, at least in the locked state of the additional connection plug in the connection terminal. It is particularly preferred in a backdrop arranged in alignment with the solvent guided. When the actuating means is guided outside, the solvent is actuated with it. This embodiment is advantageous in terms of the number of components required and ease of handling the additional connector. However, other embodiments are also preferred which, for example, provide for actuating the solvent and / or the actuating means laterally and / or at a distance therefrom. However, the additional connector plug also preferably uses the solvent already provided in the connection terminal to loosen its busbar part.

For this purpose, the actuating means, in particular the actuating end, can be a plastic part or a metal part, in particular a sheet metal part.

The additional conductor connection provided in the additional connection plugs is preferably likewise designed in direct plug-in technology. An electrical conductor can therefore also advantageously be easily and quickly connected to such an additional connector.

The additional connector arrangement particularly preferably comprises a plurality of additional connector plugs, with no more than three second additional connector plugs following each first additional connector plug. On the one hand, this ensures that all the additional connecting plugs of the additional connecting plug arrangement are securely latched in the several connecting terminals when the first additional connecting plug is locked, and on the other hand it is still possible to pull out the additional connecting terminal arrangement when the first additional connecting plug is unlocked, in particular by hand.

In a further embodiment, the additional connector arrangement is symmetrical to a first additional connector. Exactly two second additional connecting plugs are preferably arranged on both sides of a single first additional connecting plug. The additional connector arrangement particularly preferably comprises exactly five additional connectors, in particular a first and four second additional connectors. It has been shown that this number of additional connector plugs is particularly common and advantageous.

In a preferred embodiment, in particular in addition to the additional conductor connection, an electrical assembly is integrated or can be integrated in at least some of the first and / or second additional connection plugs. As a result, the possible uses of the additional connector arrangement are considerably multiplied.

It is particularly preferred that the additional connector arrangement is a test connector.

The object is further achieved with a first additional connector of such an additional connector arrangement. The first additional connector has the locking means on the busbar part and the actuating means. It enables the additional connection plug arrangement to be securely latched in a connection arrangement consisting of one or more connection terminals arranged in a row, so that the electrical contact between the contact connection cage of the connection terminal and the busbar part is reliably ensured. In addition, the additional connection plug arrangement can also be detached again after the locking means has been released from the connection terminal.

The object is further achieved with an arrangement comprising at least one terminal block which can be arranged in a row and has a conductor connection formed in direct plug-in technology, or a plurality of connected terminal blocks each having a conductor connection formed in direct plug-in technology, and such an additional connection plug arrangement. This arrangement is characterized in that at least one busbar part of a first additional connector plug of the additional connector arrangement is plugged into a conductor connection of a connecting terminal, a clamping spring of the conductor connection being latched with a latching means which is arranged on the busbar part of the first additional connector plug. In this latched state, the additional connection plug arrangement is securely inserted into the connection terminal or connection terminals and cannot come loose automatically. An electrical contact between a busbar part of the first additional connection plug and a contact connection cage of the connection terminal, into which the first additional connection plug is inserted, is then reliably ensured.

According to the invention, the additional connection plug arrangement can also be unlocked from the connection terminal (s) by actuating the actuating means of the first additional connection plug, so that the additional connection plug arrangement can be pulled out of the connection terminal (s), in particular by hand.

With regard to the complexity of the components and the ease of handling, it is advantageous and therefore preferred that the actuating means and the solvent are arranged in alignment with one another. The actuating means, in particular also the solvent, is particularly preferably displaceably or rotatably guided in a backdrop. The actuating means can also be provided in the locked state. As a result, several actuating means of several additional connecting plugs of the same additional connecting plug arrangement can be used are actuated one after the other without the previously actuated actuating means being adjusted back so that their busbar parts disengage from the clamping springs of the connection terminals into which they are inserted and remain so until the additional connector arrangement is completely released and the connection arrangement can be removed.

The invention is described below with reference to figures. The figures are only examples and do not limit the general idea of the invention. Show it:

• 1 a schematic perspective view of an embodiment of an additional connector assembly from a plurality of additional connectors;
• 2 an arrangement of the additional connector assembly of 1 and a connecting terminal arrangement comprising a plurality of connecting terminals arranged in a row, (a) showing the arrangement before the additional connecting plug arrangement is inserted into the connecting terminal arrangement, and (b) the arrangement from (a) when the additional connecting plug arrangement is inserted into the connecting terminal arrangement; and
• 3 in (a) and (b) each a partial sectional view of the arrangement 2 B) ,

1 shows an additional connector arrangement 1 from several additional connection plugs 10 . 11 , The additional connector arrangement 1 includes a centrally located first additional connector 10 and four to the first additional connector 10 second additional connector plug 11 , two of which are on both sides of the first additional connector 10 are arranged. The additional connector arrangement 1 therefore has five additional connectors here 10 . 11 on. It is provided symmetrically.

The additional connector 10 . 11 are each for plugging into a direct connector technology 40 an electrical connection terminal 4 provided (see 2 ). They each have an additional housing 32 on, in which here an additional conductor connection trained in direct plug-in technology 30 for connecting an electrical conductor (not shown) is integrated. Below are the additional connectors 10 . 11 initially using a single additional connector 10 . 11 described.

The additional conductor connection, which is designed in direct plug-in technology 30 of the additional connector 10 . 11 has an additional contact connection box 31 on, which is electrically conductive, and which preferably consists of copper or a copper alloy. The additional contact connection box 31 comprises a bus bar (not designated), a bus bar section 36 the busbar is led outside. The conductor rail section 36 is for plugging into the conductor connection 40 the electrical connection terminal 4 intended. It is not self-locking and therefore has a first layer 363 made of copper or a copper alloy with a second layer 364 is coated from steel.

In the additional conductor connection 30 an electrical conductor can be inserted. For jamming and safe electrical contact of the electrical conductor with the additional contact connection box 31 is in the additional housing 32 an additional clamping spring 33 set that an additional clamping leg 331 has about a pivot axis 2 in a swivel direction 23 is provided pivotable. The pivot axis 2 is through a peg 20 formed in one piece with the additional housing 32 is manufactured and on one side (not designated) of the additional contact connection box 31 is arranged. The additional clamping spring 33 is around the cone 20 bent so that the additional clamping leg provided for clamping the electrical conductor 331 in the additional contact connection box 31 protrudes into it. The electrical conductor can be in an insertion direction 21 through an additional conductor insertion opening 35 that in the additional housing 32 is provided between the additional clamping spring 33 and the additional contact connection box 31 be introduced. He comes into contact with the additional clamping leg 331 so that this against the swivel direction 23 around the pivot axis 2 is pivoted. When the electrical conductor is fully inserted, the additional clamping leg 331 with the restoring force of the additional clamping spring 33 in the swivel direction 23 pressed against the conductor. This will end it with an open end 332 of the additional clamping leg 331 between the additional clamping leg 331 and the additional contact connection box 31 jammed.

Around the electrical conductor the additional connector 10 . 11 To be able to remove again is an additional solvent 34 provided that above the additional clamping leg 331 in an additional backdrop (not shown) of the additional housing 32 is led. The additional solvent 34 is in and against the direction of insertion 21 slidably provided. By moving the additional solvent 34 in the direction of insertion 21 will be an open end 341 of the additional solvent 34 on the additional clamping leg 331 pressed so that this against the swivel direction 23 is pivoted and stands out from the electrical conductor. The electrical conductor is the additional housing 32 then by pulling out against the direction of insertion 21 removable again.

This structure and this mode of operation are for (additional) conductor connections designed in direct plug-in technology 30 . 40 known and also apply for the conductor connections 40 the connection terminals 4 , Components with the same function are designated there with the otherwise identical word without the leading word part "addition" and instead of a reference sign with a preceding " 3 “The otherwise identical reference number but with a preceding“ 4 " on.

Compared to the second additional connector plugs 11 has the first additional connector 10 on its track section 36 here a locking means according to the invention 361 on. The locking device 361 is designed here as a latch. The following are the terms locking means 361 and locking nose used synonymously. The latch 361 is on the coating made of steel 364 of the conductor rail section 36 arranged. The function of the locking means 361 is part of the 3 described.

To the first additional connector 10 the connection terminal 4 To be able to remove again, the first additional connector has 10 here also an actuating means according to the invention 37 on. The actuator 37 is in a backdrop (not shown) of the additional housing 32 in the direction of insertion 21 slidably guided. It is flush with an upper side (not labeled) of the additional housing 32 arranged so that it does not build up. The function of the actuator 37 is part of the 3 described.

2 shows an arrangement of the additional connector assembly 1 the 1 and a connection terminal arrangement 46 from a large number of connecting terminals 4 , wherein (a) the arrangement before inserting the additional connector arrangement 1 into the connection terminal arrangement 46 shows, and (b) the arrangement of (a) in the terminal arrangement 46 inserted additional connector arrangement 1 ,

The connection terminals 4 the connection terminal arrangement 46 are constructed identically and on a hat-shaped mounting rail 5 snapped. They each include three conductor connections using direct plug-in technology 40 , which are functionally analogous to the additional conductor connection already described above 30 the additional connector 10 . 11 are trained. The three conductor connections 40 each of the terminals 4 are via a common connection busbar 47 electrically connected to each other.

Due to the identical construction of the connection terminals 4 are the conductor connections 40 of the neighboring terminals 4 in one direction 22 arranged in alignment next to each other. As a result, the connection terminal arrangement 46 three rows (not labeled) of wire terminals 40 on. The additional connector arrangement 1 can therefore wire connections in each of the three rows 40 the connector arrangement 46 be plugged in. The busbars become the additional connector 10 . 11 the additional connector arrangement 1 into the conductor connections 40 adjacent terminals 4 plugged in.

When plugged in (not labeled), the 2 B) shows, the busbar sections 36 the additional connector 10 . 11 each by means of the clamping leg 431 the clamping spring 43 of the conductor connection 40 the connection terminal 4 into which they are inserted against the contact connection housing 41 of the conductor connection 40 pressed. In addition, the locking means latches 361 the first additional connector 10 with the clamping leg 43 of the conductor connection 40 the connection terminal 4 in which it is inserted. The additional connection terminal arrangement 1 is therefore in the connection terminal arrangement 46 locked and is in the locked state V , You can then not non-destructively and / or by hand from the terminal assembly 46 to be pulled.

The additional housing also covers 32 the additional connector 10 . 11 each the release element 34 of the conductor connection 40 the connection terminal 4 into which they are inserted. This allows the busbar section 36 the first additional connector 10 in this locked state V not with the solvent 47 of the conductor connection 40 in which it is inserted can be released. It is unlatching the track section 36 is only by means of its actuating means 37 possible.

3 shows a partial sectional view of the arrangement for clarification in (a) and (b) 2 B) ,

After inserting the first additional connector 10 into a conductor connection 40 a connecting terminal 4 is that on the track part 36 the first additional connector 10 arranged locking means 361 the clamping leg provided for clamping 431 the clamping spring 43 of the conductor connection 40 into which the first additional connector 10 is inserted, arranged facing. It snaps into place when the first additional connector is inserted 10 in the direction of insertion 21 with the open end 432 of the clamping leg 431 the clamping spring 43 , In this locked state V is the first additional connector 10 the conductor connection 40 therefore not non-destructive and / or removable by hand. The locked state V shows 3 (a) ,

The actuator is used for unlatching 37 the first additional connector 10 in the direction of insertion 21 pressed so that it is along the Backdrop in the additional housing 32 is provided is moved. This will be an open actuation end 372 of the actuating means 37 from the additional housing 32 led out to the outside. The open actuation end 372 gets into contact with the solvent 44 and push it in the direction of insertion 21 ,

By moving the solvent 44 in the direction of insertion 21 becomes the open end 441 of the solvent 44 on the clamping leg 431 pressed so that this against the swivel direction 23 is pivoted and away from the locking means 361 and the track 36 the first additional connector 10 solves. This is the connection terminal 4 then by pulling out against the direction of insertion 21 removable again. This shows the 3 (b) , Because the track sections 36 all additional connector 10 . 11 are not designed to be self-locking, then the second additional connecting plugs attached to it are also 11 with him against the direction of insertion 21 from the connection terminal arrangement 46 pulled out.

The first additional connector 10 or such an additional connector arrangement 1 is therefore not only safe in a connection terminal arrangement 46 latched. But he or she is the connection terminal arrangement 46 also easy and quick to remove again without destroying it.
