DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric junction box installed adjacent to an automobile battery.

[0002]

2. Description of the Related Art A battery of an automobile and an electric connection box are connected by a thick electric wire having a large current capacity. However, thick electric wires have high rigidity and are difficult to bend, so that wiring is difficult in an engine room where many parts are densely packed. Therefore, it has been considered to install a battery and an electric junction box adjacent to each other, and connect the battery electrode and the bus bar of the electric junction box with a short conductor, thereby eliminating the need to wire thick wires in the engine room. I have.

[0003]

However, since the size of an automobile battery varies depending on the type and grade of the vehicle, the distance and height of the electrodes of the battery vary accordingly. When the battery and the electric connection box are installed adjacent to each other, it is preferable that the terminal portion of the bus bar of the electric connection box has the same interval and the same height (or a certain height difference) as the electrodes of the battery. Since busbars are manufactured by punching and bending using press dies, if busbars are made to match the electrode spacing and height of the battery, it is necessary to prepare various types of dies, and equipment costs will only increase In addition, the number of types of electric connection boxes increases, which increases costs.

In view of the above problems, an object of the present invention is to provide a battery-adjacent-type electric connection box which can accommodate a plurality of types of batteries having different electrode intervals and heights without changing a bus bar. It is in.

[0005]

In order to achieve this object, the present invention provides:
In an electrical junction box that is installed adjacent to the battery and is connected so that the electrode of the battery and the terminal of the bus bar are connected by a short conductor, a hole through which the electrodes of multiple types of batteries with different electrode intervals can penetrate is provided. A terminal holder is installed on the battery, and a fixing portion is provided on the terminal holder to fix the electrode terminal in accordance with the electrode interval of the battery.The electrode terminal fixed to the fixing portion and the terminal of the bus bar of the electric connection box are provided. And a portion connected by a flexible conductor.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIGS. 1 to 4 show an embodiment of an electric connection box installed adjacent to a battery according to the present invention. In the figure, 11 is a battery, 13 is an electrode of the battery 11, 15 is an electric connection box, and 17 is a battery 11 and an electric connection box.
It is an integrated case that accommodates 15. As before, the electric connection box 15 has a lower case 19, an upper case 21, a bus bar 23, an insulating plate 25,
It is composed of a fuse 27, a relay 29 and the like.

Reference numeral 31 denotes an electrode terminal attached to the electrode 13 of the battery, 33 denotes a terminal holder for fixing the electrode terminal 31 in accordance with the distance between the electrodes 13 of the battery, and 35 denotes a bus bar in the electrode terminal 31 and the electric connection box 15.
It is a short braided conductor (flexible conductor) that connects to 23 terminals.

The terminal holder 33 has a long hole 37 through which the electrodes of a plurality of types of batteries having different electrode intervals can be penetrated.
11 (see FIG. 3). Further, the terminal holder 33 has a fixing portion 39 of the electrode terminal 31 on the side of the electric connection box 15 in the elongated hole 37. 2 (b),
A pierce nut 41 is incorporated as shown in FIG. The pierce nut 41 is slidable in a direction to increase or decrease the interval between the electrode terminals 31. Reference numeral 43 denotes a retaining piece for the pierce nut 41.

The electrode terminal 31 is fixed to a terminal holder 33 as shown in FIGS. That is, on the pierce nut 41, a terminal portion 31a of the electrode terminal 31, one terminal portion 35a of the braided conductor 35, and a washer
It is fixed by stacking 45, passing the bolt 47, and screwing it into the pierce nut 41. FIG. 2D shows a case where the electrode spacing of the battery is small, and FIG.
The electrode terminal 31 has a structure in which an electrode of a battery is tightened by tightening a nut 49.

Since the electrode terminal 31 is fixed to the electrode terminal 31 in this manner, the fixing position can be adjusted within the range of the adjustment width W as shown in FIG.
A plurality of types of batteries 11 having different electrode intervals can be supported.

FIG. 3 shows the electrode terminal 31 fixed to the terminal holder 33 as described above,
13 while the other terminal 35b of the braided conductor 35 is connected to the terminal of the bus bar 23. FIG.
(A) shows a case where the level (height of the electrode 13) of the upper surface of the battery 11 is lower than that of the electric connection box 15, (c) shows a case where the level is high, and (b) shows a case between them. . As described above, it is possible to flexibly cope with a variation in the height of the electrode 13 of the battery 11 without changing the bus bar 23 of the electric connection box 15.

[0012]

As described above, according to the present invention, the electrode terminal is fixed to the terminal holder at the same interval as the battery electrode, and the electrode terminal and the terminal portion of the bus bar are connected by the flexible conductor. Since it is possible to cope with a plurality of types of batteries having different electrode intervals and heights without changing the bus bar of the electric connection box, the number of types of electric connection boxes can be reduced, which is economical.
