Description of the Related Art A terminal block is provided with connecting portions on the left and right sides of a terminal block main body, a conductive plate is inserted between both connecting portions, and a conductive wire is electrically connected to an end of the conductive plate via a connecting means. Various proposals have been made. As a connection means used for such a terminal block, a means for directly connecting a crimp terminal connected to a conductor to a conductive plate by a connection screw is generally used. However, in such a configuration, it is necessary to connect the crimp terminal to the conductor, and it is troublesome to rotate the connection screw.

る端子台である。SUMMARY OF THE INVENTION The present invention comprises left and right connecting portions communicating with connection holes into which electric wires formed in a terminal block main body are inserted, and a conductive plate is inserted between the two connection portions. In the terminal block adapted to electrically connect the conductive wire of the wire inserted from the conductive plate to the conductive plate, a moving end disposed at a position crossing the connection hole, and a curved inward from the moving end. A pressing back portion that is extended and faces the operation hole, and a holding base portion that is extended from the pressing back portion and held by the terminal block main body,
The moving end is provided with a plate-shaped baying spring in which a lead wire insertion hole is formed at both connection portions, and the connection ends erected on both sides of the conduction plate are inserted into the lead wire insertion hole, and at a steady position, The lead wire can be held between the front edge and the connection end of the lead wire insertion hole by the restoring elasticity of the bay moving spring, and the lead wire is attached to the operation hole formed in the terminal block main body so as to be able to move forward and backward. Push the pressing back of the dynamic spring outward, move the moving end to the position where the wire insertion hole matches the connection hole, and from the wire insertion hole, between the front edge of the wire insertion hole and the connection end. A wedge-shaped pressing button that allows insertion of a conductive wire.

線挿入孔の前縁と結線端部間で導線が挟持される。In this configuration, when the wedge-shaped push button is pushed in and the pushing back portion of the bay motion spring is pressed outward, the moving end of the bay motion spring moves outward, and the lead wire insertion hole is connected to the connection hole. An opening is formed between the front edge of the wire insertion hole and the connection end, so that the wire can be inserted or removed from the wire insertion hole. Also, when the pressing operation of the wedge-shaped pressing button is released, the moving end moves backward, and the conductor is held between the front edge of the conductor insertion hole and the connection end by the restoring elasticity of the spring.

能となる。[0007] As described above, since the lead wire is sandwiched by the restoring elasticity of the bay dynamic spring directly acting, the connection strength is high. In addition, since the pushing operation of the bay moving spring is performed by the wedge-shaped pressing button, the pressing back portion of the bay moving spring located in the inner part can be gradually pushed in, and a reasonable pushing operation can be performed.

作が容易となる。On the other hand, a locking step for locking the wedge-shaped pressing button at the maximum pressing position is formed in the operation hole, and the wedge-shaped pressing button is disengaged from the locking step, so that the pressing back can be moved. The wedge-shaped pressing button may be returned to the normal position by the restoration elasticity. In this case, the wedge-shaped pressing button can be held at the large pressing position by the locking step. Therefore, the operator can concentrate on inserting the electric wire into the connection hole, and the operation becomes easy.

Insert At this time, as shown in FIGS. 10B and 10C, the flexible locking claws 67 are retracted downward with the insertion of the name plate 75 by the guiding action of the inclined surface 69, so that the insertion is possible. Then, the final end engages with the flexible locking claw 67, and as shown in FIG. 9C or FIG. 10D, a long name plate 75 is fitted into the row of the holding grooves 65. Become. FIG. 10 shows the case where one terminal block is used, and FIG. 9 shows the case where the nameplate 75 is applied to one row of terminal blocks, but the operation is the same. Thus, in the present invention, only a single terminal block 1 may be used. The configuration using the holding groove 65 can be used outside the present invention.

る。As described above, according to the present invention, a moving end disposed at a position crossing a connection hole, and a pressing back extending inward from the moving end and facing the operation hole. And a holding base portion extended from the pressing back portion and held by the terminal block main body. Inserting the connection ends erected on both sides into the conductor insertion hole, and in a stationary position, the lead wire can be held between the front edge of the conductor insertion hole and the connection end by the restoring elasticity of the bay spring, and the terminal block body When the wedge-shaped push button attached to the operation hole formed in is pressed by a tool,
Pressing the pressing back of the bay dynamic spring outward, moving the moving end to a position where the wire insertion hole coincides with the connection hole, creating an opening between the front edge of the wire insertion hole and the connection end, In this configuration, the conductor can be detached or inserted from the connection hole.

In addition, by operating the wedge-shaped push button with a tool, the pressing back is gradually pushed in, so that no force is applied and a smooth pushing operation is possible, and the moving end of the bay spring is easily moved outward. You can move. In addition, since the operation hole is blocked by the wedge-shaped push button and the bay spring is shielded, there are excellent effects such as being safe even when a high voltage is applied to the conduction plate.
