DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device called a quick connection terminal for connecting electric wires by a locking spring applied to a circuit breaker for wiring, a leakage breaker, a switch and the like.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional quick-connecting type terminal device applied to a circuit breaker for wiring or the like has a locking spring for pressing an inserted electric wire 1 toward a lower surface of a terminal 2. As shown in FIG. 3 and
It comprises a release lever 4 pivotally mounted above the locking spring 3. When the release lever 4 is rotated toward the main body from the state shown in FIG. 5, the lower unlocking portion 5 presses the locking spring 3 to release the pressed state, thereby enabling the electric wire 1 to be detached. It is.

However, in such a conventional quick-connecting terminal device, when wiring to a wiring breaker in a distribution board installed near a ceiling at a construction site or the like, the release lever is in one direction. work is there is a case Dzu leprosy.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a terminal device capable of facilitating the operation of a release lever and improving the efficiency of wiring work at a construction site or the like. It was made to provide.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a terminal device of the present invention is provided with a locking spring for pressing an electric wire to a terminal, and an oscillating type for releasing the pressing state of the locking spring. of a terminal device provided with a release lever, the release lever in addition to the first unlocking portion of the ordinary that can lock in a state of depressing the upper surface of the locking spring when it is rotated in a predetermined direction, opposite the release lever when released force depressed but pushes down the upper surface of the locking spring can to have been rotated in the direction to the locking state
It is characterized by having a second unlocking portion for returning .

[0006]

In the terminal device of the present invention, since the two unlocking portions are provided on the release lever as described above, the upper surface of the locking spring is rotated by rotating the release lever in a predetermined direction as in the prior art. Besides it is possible to release the pressing state is locked depressed, also releasing the pressure state by rotating the release lever in the opposite direction and push under in this case
When the release force is released, the release lever can be returned to the locked state . For this reason, since the release lever can be rotated in both directions at a construction site or the like, the work is facilitated, and the efficiency of the wiring work can be increased.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in FIGS. 1 and 2, reference numeral 1 denotes an electric wire, 2 denotes a terminal fixed to the main body, 3 denotes an inverted U-shaped locking spring, and 4 denotes a release lever pivotally mounted by a shaft 6 above the spring. The lock spring 3 is formed with a hole 7 through which the terminal 2 and the electric wire 1 are inserted. The electric wire 1 is pulled up by the spring force of the lock spring 3 as shown in FIG. It can be brought into close contact with the lower surface.

On the lower surface of the release lever 4, a first unlocking portion 8 and a second unlocking portion 9 are provided. The first unlocking section 8 is shown in FIG.
When the release lever 4 is rotated in a predetermined direction (toward the main body) as shown in FIG. 5, the upper surface of the locking spring 3 is pushed down, and the pressing state of the electric wire 1 against the lower surface of the terminal 2 can be released. Be free. In this state, the release lever 4 receives a clockwise rotational moment from the locking spring 3, so that the release lever 4 is locked and remains in this state unless it receives an external force.

As shown in FIG. 4, the second unlocking portion 9 pushes down the release lever 4 in the opposite direction to thereby release the lock spring 3.
Is pressed down, the pressing state of the electric wire 1 against the lower surface of the terminal 2 can be released, and the electric wire 1 can be inserted and removed. The state of FIG. 4 returns to the state of FIG. 2 when the pressing force on the release lever 4 is released. The first unlocking portion 8 and the second unlocking portion 9 are provided on both sides of a perpendicular passing through the center of the shaft 6 in the state shown in FIGS.

[0010] Such terminal device of the present invention constructed as above, to release the pressing state by depressing the conventional manner to the upper surface of the locking spring 3 by rotating the release lever 4 in a predetermined direction as shown in FIG. 3 Because you can lock to the state
Insertion and removal of the electric wire 1 can be performed in the same manner as in the related art. The terminal apparatus of the present invention, placed in the groove 10 of the release driver ahead like lever 4 as shown in FIG. 4, the release lever 4 from the normal by the pressing down in the opposite direction, a downward force is added
The insertion and removal of the electric wire 1 can be performed only during the operation . In the distribution board, the power supply side of the branch wiring breaker is connected to a bar, but in such a case, the release lever 4 is rotated in a predetermined direction and locked, and the bar is simultaneously connected to a plurality of wiring breakers. Wiring can be performed by inserting and returning the release lever 4 to its original position. When wiring to the circuit breaker in the distribution board installed near the ceiling at the construction site, if the release lever 4 is difficult to rotate in the predetermined direction, push down the release lever 4 in the opposite direction to normal. As a result, the wire can be inserted, so that the efficiency of wiring work can be improved.

[0011]

As described above, the terminal device of the present invention can be used as usual, and can also be inserted and removed by operating the release lever in the opposite direction to the normal operation. Therefore, the direction of rotation of the release lever can be selected, which is extremely effective in increasing work efficiency.
