The quick connection terminal unit 1 is used, for example, in a distribution board. The quick-connect terminal unit 1 has a main case 2 which is assembled from a front case 2a and a rear case 2b, which are two synthetic resin cases that can be divided into front and rear parts. An insertion hole 3 into which an electric wire 21 can be inserted is provided on the top surface. Further, on the right side of the bottom surface of the main body case 2, a groove-shaped holding portion 4 cut upward is provided. The holding part 4 has the same horizontal width as the thickness of the copper bar 20, and the front and rear parts of the holding part 4 are open to the front and back of the main body case 2, so that it can be used, for example, as a distribution board. The placed copper bar 20 can be sandwiched therein.

Furthermore, an accommodation space 5 into which the electric wire 21 is inserted through the insertion hole 3 is provided inside the main body case 2 . The accommodation space 5 is surrounded by an upper wall, a front wall, a rear wall, a left wall, and a lower wall, and the right side of the accommodation space 5 communicates with the inside of the holding part 4. Hole 3 is open.

Further, in the accommodation space 5, a quick connection terminal fitting 6 is installed, which has a connection spring 15, a retaining spring 16, and a connection part 22 that connects both springs. The quick-connect terminal fitting 6 is held by a holder 10. The connection spring 15 is curved into a substantially N-shape when viewed from the front, and the portion that bulges out to the right is located near the communication portion between the accommodation space 5 and the holding portion 4 . The connecting portion 22 is located along the left wall from one end of the left side of the connecting spring 15 toward the upper wall. The retaining spring 16 is formed into a plate shape that is inclined toward the holding portion 4 from one end on the upper wall side of the connecting portion 22 . Further, 17 is a protrusion provided at the tip of the retaining spring 16.

Further, the accommodation space 5 is provided with a wire release lever 7 that is operated when removing the wire 21. The wire release lever 7 has a fulcrum hole 18 formed therein, and its position is determined by a longitudinal screw (not shown) that passes through the fulcrum hole 18 and fixes the front case 2a. Further, the wire release lever 7 is rotatable about a screw passing through a fulcrum hole 18 on the front side of the quick-connect terminal fitting 6. The operating portion 9 of the wire release lever 7 protrudes from the upper surface of the main body case 2. Furthermore, a release protrusion 19 is formed at the tip of the wire release lever 7 so as to protrude above a protrusion 17 provided at the tip of the retaining spring 16.

Further, a lock lever 8 is provided on the left side surface of the main body case 2. The lock lever 8 is slidable in the left-right direction between a locked position in which the tip extends beyond the holding part 4 and extends to the right side of the main body case 2, and a released position in which the tip is pulled in to the left side of the holding part 4. be.

In the quick connection terminal unit 1 configured as described above, a procedure for attaching it to the copper bar 20 inside the switchboard and connecting the electric wire 21 will be explained.
First, with the lock lever 8 in the release position, the copper bar 20 is held between the holding parts 4, and the copper bar 20 held between the holding parts 4 passes through the main body case 2 in the front and back directions, and the quick-connect terminal is assembled. 1 to the copper bar 20. Next, as shown in FIGS. 6 and 7, the lock lever 8 is operated to the lock position. When the quick-connect terminal unit 1 is fixed to the copper bar 20 in this manner, the copper bar 20 is exposed on the right side of the accommodation space 5. Therefore, when the electric wire 21 is inserted into the accommodation space 5 from the insertion hole 3, the electric wire 21 is directly pressed against the copper bar 20 by the quick-connect terminal fitting 6, and the electric wire 21 and the copper bar 20 are connected to each other, as shown in FIGS. are electrically connected.

Next, a procedure for removing the electric wire 21 from the quick-connect terminal unit 1 will be described.
First, by moving the operation part 9 of the wire release lever 7 from the left side to the right side, the wire release lever 7 moves counterclockwise in front view around the screw passing through the fulcrum hole 18, as shown by the two-dot chain line in FIG. The release protrusion 19 moves downward as the release protrusion 19 rotates. By moving the release protrusion 19 downward, the protruding piece 17 at the tip of the retaining spring 16 is pushed down, and the distal end of the retaining spring 16 and the protruding piece 17 are tilted toward the connection spring 15. Finally, the tip of the retaining spring 16 and the protrusion 17 are released from biting into the electric wire 21, and the electric wire 21 can be removed.

According to the quick-connect terminal unit 1 having the above-described configuration, the main body case 2 includes a holding part 4 that holds the copper bar 20 between them, and a holding part 4 that is parallel to the surface of the copper bar 20 held by the holding part 4. An insertion hole 3 into which the electric wire 21 can be inserted in the direction is provided, and the electric wire 21 is inserted into the interior of the main body case 2 through the insertion hole 3, and a copper bar held by the holding part 4 is provided. A housing space 5 is provided in which the wire 20 is exposed, and a quick connection terminal fitting 6 for pressing the inserted electric wire 21 against the copper bar 20 is installed in the housing space 5. Therefore, when the electric wire 21 is inserted into the housing space 5 through the insertion hole 3, the electric wire 21 is pressed against the copper bar 20 by the quick-connect terminal fitting 6, and the electric wire 21 and the copper bar 20 come into direct contact with each other, causing electricity to be generated. connected. Therefore, there is no need to separately provide a conductive part via the electric wire 21 and the copper bar 20 inside the quick connection terminal unit 1. Therefore, it is possible to reduce the number of parts of the quick-connect terminal unit 1 and to make the quick-connect terminal unit 1 smaller.

Further, the copper bar 20 and the electric wire 21 can be easily connected by only the steps of attaching the quick-connection terminal unit 1 to the copper bar 20 and inserting the electric wire 21 into the insertion hole 3.
Further, since a wire release lever 7 is provided that can press the quick-connect terminal fitting 6 to release the wire 21 from being held by the quick-connect terminal fitting 6, the wire release lever 7 can be easily operated. The electric wire 21 can be removed from the quick-connect terminal unit 1.

Note that the quick-connect terminal unit according to the present invention is not limited to the aspects of the above-described embodiments, and the configuration of the main body case such as the position of the insertion hole and the holding part, the configuration of the quick-connect terminal fitting, etc. Appropriate changes can be made as necessary without departing from the spirit of the invention.

For example, in the above embodiment, in the main case of the quick-connect terminal unit, the insertion hole is formed by cutting into the top surface and the holding part is formed by cutting from the bottom surface, but it is possible to insert the electric wire in a direction parallel to the copper bar. The same effect can be achieved by opening the insertion hole not only on the top surface but also on the front surface, the back surface, etc., or forming the holding part in the shape of a cut from the top surface.
