[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dark current circuit connecting / disconnecting mechanism capable of easily interrupting a dark current circuit without operating a dark current fuse in order to prevent consumption of a battery when the vehicle is not used. Is.

[0002]

2. Description of the Related Art FIGS.
2 shows an interrupting mechanism of a conventional dark current circuit described in Japanese Patent Laid-Open Publication No. This mechanism is for disconnecting the dark current circuit connected to the direct connection parts in order to prevent the consumption of the battery by the operation of the direct connection parts of the battery before the vehicle is handed over to the user. The dark current fuse 4 is engaged in the holding wall 62 of a substantially rectangular tube shape standing upright in 61 so as to be able to move up and down.

Below the holding wall 62, the dark current fuse 4 is provided.
20 is provided with an insertion portion 63 for the male tab terminal 5, and a locking projection 64 is formed at an intermediate portion of the holding wall 62. As shown in FIG. 20, between the locking projection 64 and the stop claw 65 above the holding wall 62. The dark current fuse 4 is held. In this holding state, the terminal 5 of the fuse 4 is pulled out from the insertion portion 63,
The dark current circuit is in the cutoff state.

[0004]

However, in the above-mentioned conventional mechanism, since the dark current fuse 4 is moved up and down along the holding wall 62 when the dark current circuit is interrupted, the height of the holding wall 62 is a fuse. At least twice the height of No. 4 is required, and there is a problem in that the fuse box 61 is enlarged. In addition, the insertion portion 6 having a pair of female terminals 66
There is a problem that a large force is required for inserting and removing the dark current fuse 4 with respect to 3, and the work is difficult.

In view of the above points, the present invention prevents the size of the fuse box in which the dark current fuse is installed from increasing, and allows the dark current circuit to be easily installed without inserting and removing the dark current fuse which requires a large force. It is an object of the present invention to provide an interrupting mechanism of a dark current circuit that can be interrupted.

In a disconnecting mechanism of a dark current circuit for accommodating a terminal, the pair of blocking members provided with an insertion hole in the holding wall and having a pair of insulating plates that can enter between the pair of contact spring pieces and the male tab terminal. The mechanism is based on the mechanism of inserting the insulating plate into the holding wall through the insertion hole.

A second mechanism, or a slide board in which the blocking member is engaged with the holding wall so as to be able to move up and down, and a pair of insulating plates protruding from the slide board. A third mechanism having an insertion space for the pair of insulating plates that is continuous with the contact spring pieces is also effective.

Further, in the interrupting mechanism of the dark current circuit, the dark current fuse is held in the holding wall and the female type terminal having the pair of contact spring pieces for the male tab terminal of the dark current fuse is accommodated in the holding wall. A fourth mechanism in which a vertically long through hole is provided, a blocking member having a projecting pin for the through hole is engaged with the holding wall in a vertically movable manner, and an engaging hole for the projecting pin is provided in the female terminal. Is also possible.

In the first mechanism, the cutoff member is rotated to allow the pair of insulating plates to enter the insertion holes, so that the pair of insulating plates causes one of the pair of contact spring pieces of the female terminal and the dark current fuse. , And the dark current circuit is cut off.

In the second mechanism, the blocking member is positioned on the slide member with the insulating plate standing upright, and the sliding member is raised while the insulating plate is inserted into the insertion hole to insulate the blocking member. The plate is pushed by the slide member and inserted between the contact spring piece and the male tab terminal. Then, the substrate portion is brought close to the inner wall portion of the slide member to prevent the slide member from coming out.

In the third mechanism, the insulating plate is located in the insertion space of the female terminal at the lowest position of the slide substrate, and the insulating plate is moved from the insertion space to the contact spring piece by the ascending operation of the slide substrate. It rises and is located between the male tab terminal and the contact spring piece to interrupt the dark current circuit. In the fourth mechanism, by the lowering operation of the blocking member, the female terminals engaged with the projecting pins are integrally lowered and separated from one male tab terminal of the dark current fuse.
