BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric circuit for a motor vehicle, and more particularly to a short-circuit pin for shutting off the power consumption of a circuit that consumes power even during a suspension of operation.

[0002]

2. Description of the Related Art As is well known, wiring of various electric devices in an automobile is generally collected in a fuse box and connected to a battery via an ignition switch or another changeover switch via a fuse corresponding to the capacity of the various electric devices. Have been.

[0003] Usually, when the car is out of service, that is,
When the ignition switch is turned off, no current flows to these devices, but the watch and engine control unit are always in operation, but the current is always flowing in preparation for clock operation and engine operation. It is wired as follows.

[0004] However, the current (dark current) flowing during the suspension of operation is only a very small amount. However, if the operation is suspended for a long period of time, such as during loading during export, the battery is consumed.

Therefore, conventionally, several kinds of fuses for electric equipment such as a clock and a control unit, which consume a battery even during suspension of operation during loading and unloading, are pulled out of a fuse box, and when arriving on site, the pulled out fuses are reinserted. However, since the operation of pulling out and reinserting the fuses described above is performed in a narrow place, it is difficult, and there is a risk that the pulled out fuses may be lost. For this reason, there has been disclosed an apparatus in which a changeover switch is provided in place of pulling out a fuse (Japanese Utility Model Application Laid-Open No. 5-6647).
issue).

[0006]

However, recently, as automobiles have become more sophisticated, wiring to various electric devices that are not connected to the ignition switch has been increasing. The work of pulling out and reinserting when arriving at the site is very complicated, and there is a risk of losing the removed fuse.When reinserting, it is necessary to check the capacity of each fuse and insert it in a predetermined position. However, this confirmation and insertion work was extremely complicated.

Further, in order to eliminate the above-mentioned complicated work, in order to provide the above-mentioned changeover switch corresponding to each fuse, it is necessary to raise a mold for a dedicated fuse box. A switch mechanism must be assembled, which is a serious problem both in terms of work and cost. On the other hand,

According to the present invention, a conventional fuse box is slightly changed, and a short-circuit pin having substantially the same shape as a large number of other fuses is detachably provided in the fuse box. The present invention is characterized in that the power supply to a plurality of various electric devices not connected to the ignition switch is collectively cut off or connected by attaching and detaching the pins.

That is, according to the present invention, in an electric circuit of an automobile connected from a battery to various electric devices via a fuse, a circuit in which a current always flows even during a suspension of operation is integrated into one circuit on the battery side with respect to the fuse. , An insertion guide to which the short-circuit pin 2 can be attached and detached.

[0010]

According to the present invention, it is possible to simultaneously cut off the power supply to a plurality of electric devices that consume power even when the operation is stopped by simply pulling out one short-circuit pin. In this case, simply by inserting the single short-circuit pin that has been removed, the state of energization to the plurality of electric devices can be obtained all at once.

Although the short-circuit pin has almost the same shape as other ordinary fuses, but is incompatible with each other, the extraction can be performed in the same manner as the extraction of the fuse, but there is a risk that the short-circuit pin may be inserted by mistake for another fuse.

The ignition switch 1 is connected to a plurality of various electric devices A, B,
Wirings leading to C and D are provided via fuses F ₁ , F ₂ , F ₃ and F ₄ each having a predetermined capacity.

Reference numeral 2 denotes a short-circuit pin according to the present invention connected to the battery V. A wire leading to a plurality of various electric devices X, Y, and Z that consume power even during a stop of operation is provided before the short-circuit pin 2. Fuses F ₅ , F ₆ ,
It is provided via the F _7.

Each fuse F provided in the wiring leading to X, Y, Z
As shown in FIG. 2, the upper half of the fuse element 5 (soluble) connected between two parallel terminals 6 on the same plane as shown in FIG. A mini-blade type fuse (hereinafter simply referred to as a "mini-fuse") covered with an insulating housing 8 provided with a mini-fuse 7 is used. 6, an insertion opening 11 into which 6 fits,
A flat U-shaped guide 12, 12 for guiding both sides of the housing 8 is provided symmetrically on the outer periphery of the guide.

On the other hand, the short-circuit pin 2 is formed by connecting the upper ends of two parallel terminals 6 on the same plane having the same shape as the mini-fuse F as shown in FIG. The upper half portion of the metal element 13 integrally connected on the same plane with the material is provided with two wide grooves 14 wider on both sides than the grooves 7, 7 of the mini-fuse F, respectively.
14 and covered with an insulating housing 15 having a slightly larger outer width by the dimension of the groove wider than that of the mini-fuse F.

The mounting portion on the side of the fuse box into which the short-circuit pin 2 is inserted is provided with insertion ports 11, 11 into which the two terminals 6, 6 of the short-circuit pin 2 fit. It has guides 16, 16 of a flat C-shape to guide it symmetrically.

That is, the width L of the housing 15 is set to be larger than the dimension M between the inner walls of the guides 12 of the mini-fuse F, so that the short-circuit pin 2 does not fit into the mounting portion on the mini-fuse side. Conversely, the dimension N between the outer edges of the concave grooves 7, 7 of the mini-fuse F is set to be the same as the dimension P between the inner edges of the flat C-shaped guides 16, 16 of the short-circuit pin mounting portion. The mini fuse F does not fit into the mounting portion of the short-circuit pin 2. Therefore, there is no possibility that the mini-fuse F and the short-circuit pin 2 are confused and erroneously inserted.

In the illustrated embodiment, the terminal insertion opening 11 in the mounting portion is the same as the mini-fuse F, and the mini-fuse F or the guide 12 or 16 of the mounting portion, the mini-fuse F or the short-circuit pin 2 Although the embodiment in which the compatibility is lost in the dimensional relationship with the housing 8 or 15 has been described, the positions of the concave grooves 7 provided on both side surfaces may be shifted.

In addition, the minifuse F and the insertion holes 11, 11 and the guides 12 and 16 of the terminals of the short-circuit pin 2 in the mounting portion have the same form, and the housings 8 and 15 of the mini-fuse F and the short-circuit pin 2 also have the same shape. In the form, the terminals 6, 6 of the short-circuit pin 2
The compatibility of the two can be eliminated by making the width or thickness of the terminals larger than the terminals of the mini-fuse F, or by changing the distance between the terminals 6,6.

In addition, for example, the housing 15 of the short-circuit pin 2
A protrusion (not shown) is provided on the lower surface at the center, and a hole (not shown) in which the protrusion fits is formed between the two insertion holes 11 in the mounting portion on the short-circuit pin 2 side. By not forming a hole in which the projection fits in the mounting portion, the compatibility between the short-circuit pin 2 and the mini-fuse F can be lost.

Further, in the above embodiment, the mini fuse F has been described as an example, but this fuse is a blade type fuse which is currently widely used (Japanese Patent Publication No. 54-36726).
The technology of the present invention can also be applied to (i).

As described above, according to the present invention, the battery side of the wiring connected to a plurality of electric devices that consume power even during operation suspension is integrated into one circuit, and the battery is connected to this circuit via a short-circuit pin. By connecting and disconnecting one of the short-circuit pins, it is possible to turn on / off the energization states of a plurality of electric devices at the same time.

Since the short-circuit pin is not compatible with the mini-fuse, erroneous insertion can be prevented. Since this short-circuit pin has a shape similar to that of other mini-fuses, it can be obtained inexpensively with a simple structure, and can be easily pulled out using a conventional pull-out clip for mini-fuses.

In addition, a short-circuit pin mounting portion is provided with a guide similar to the mini-fuse guide but in a form to prevent the mini-fuse from being inserted around the same terminal insertion openings 11 and 11 as the mini-fuse. This guide can be obtained with a slight modification of the conventional fuse box.
Inserting male terminal fuses into 1, 11
Because it is one in which production change of the fuse box can be easily and inexpensively obtained.
