DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connection device for a battery used for connection to a battery terminal mounted on an automobile, for example.

[0002]

2. Description of the Related Art An example of a conventional electrical connection device for a battery is shown in FIG. That is, reference numeral 1 denotes a vehicle-mounted battery, and a connection ring 3 of a battery post 2 provided on the battery 1 is fastened by bolts 4 and nuts 5. Further, a substantially U-shaped fitting portion 7 formed at one end of a substantially L-shaped connecting plate (bus bar) 6 is fitted into the connecting ring 3 and connected to the fitting portion 7. The connecting ring 3 and the connecting plate 6 are connected and connected by a bolt 8 and a nut 9 that penetrate the ring 3. A cable 10 is connected to the other end of the connection plate 6.
Are connected.

[0003]

However, in the battery electric connecting device having such a structure, the connecting ring 3 fastened around the battery post 2 and the connecting plate 6 have the same connection. Since there is no means for regulating the direction in which the plate 6 is pulled out, the direction in which the connection plate 6 is pulled out from the battery post varies depending on the operator. In such a situation, there is a problem that the connection plate 6 connected to the battery post and the cable 10 connected to the connection plate 6 interfere with other components and, for example, cannot be wired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and a connecting plate connected to a battery post is provided with a restricting member for restricting the drawing direction of the connecting plate. It is an object of the present invention to provide an electric connector for a battery which has an attached structure so that the connecting plate can be pulled out in the same direction even when any worker performs the assembling during the attaching operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. However, since a battery post, a connecting ring fastened to the battery post and a structure of a fastening member thereof are not different from those of the conventional example. The same reference numerals as those in the conventional example are assigned, and the description of the structure is omitted.

In FIG. 2, reference numeral 11 denotes a battery post 2
A connecting plate connected to the connecting ring 3 fastened to the connecting ring 11. One end of the connecting plate 11 is in contact with a through hole 12 through which the bolt 8 is inserted and a side surface of the connecting ring 3. It has a side wall 13 and, at the other end of the connection plate 11, a caulked connection portion 14 for connecting the cable 10 is formed. Further, a pair of left and right ridges 15 having a substantially L shape are formed near the side wall 13.

Reference numeral 16 denotes a positioning member formed of an insulating material. The positioning member 16 includes a guide groove 17 into which the pair of protrusions 15 are fitted, a locking claw 18 to maintain the fitting, and The positioning piece 19 to be in contact with the side wall of the battery is integrally formed. Reference numeral 20 denotes a reinforcing rib of the positioning piece 19.

The above is the configuration of the present embodiment. Next, the operation will be described. First, the positioning member 16 is attached to the connecting plate 11. The positioning member 16 can be connected to the connection plate 11 by inserting it into the fitting groove 17 of the positioning member 16 and locking the locking claw 18 of the positioning member 16 to the connection plate 11.

Next, the connecting plate 11 to which the positioning member 16 is connected is fastened to the connecting ring 3 through the through hole 12 and the bolts 8 and the nuts 9.
Positioning piece 19 of positioning member 16 connected to
Abuts against the outer wall surface of the battery 1, thereby restricting the expenditure direction of the connection plate 11.

Therefore, according to this embodiment, the connection plate 11
Is connected to the connection ring 3 which is previously fastened and held to the battery post 2 by contacting the positioning piece 19 of the positioning member 16 connected to the connection plate 11 with the outer wall of the battery. The expenditure direction of the connection plate 11 is regulated, so that the expenditure direction of the battery cable is constant for any worker, and the workability of attaching the connection plate 11 is improved.

The positioning member 16 fitted to the connection plate 11 is detachable from the connection plate 11, so that a plurality of types of positioning members can be prepared as necessary to suit a vehicle type. It is easy to regulate the direction in which the battery cable is pulled out.

[0012]

As described above, the present invention is fastened to the battery post 2 projecting upward from the upper surface of the battery,
And a connecting ring 3 having a bolt 8 for screwing a connecting plate, and a connecting plate having a through hole 12 through which the bolt 8 passes at one end and a cable 10 connected to the other end. In the electric connection tool, a pair of right and left ridges 15 formed in a substantially L-shape are formed on both side edges near one end of the connection plate 11 to detachably fit the positioning member 16. The positioning member 16 is formed of an insulating material, and has a guide groove 17 into which a protrusion formed on the connection plate 11 is removably fitted. This is an electric connector for a battery in which a positioning piece 19 for positioning the connection plate 11 fitted with the connection plate 11 is integrally formed. According to this, the connection plate 11 is fastened and held in advance to the battery post 2. Connecting ring When allowed to connect to, the connection plate 1
1 positioning piece 19 of positioning member 16 fitted
Is abutted against the outer wall of the battery, so that the connection plate 11 is restricted from rotating in the circumferential direction around the battery post 2 and the expenditure direction, and as a result, Also, the expenditure direction of the battery cable becomes constant, and the mounting workability at a fixed position can be easily performed without swinging (rotating) the connection plate 11 with respect to the battery post.

The positioning member 16 fitted to the connection plate 11 is detachably fitted to the connection plate 11, so that the positioning member 16 can be exchanged with a positioning member having a different size if necessary. Can be easily performed.
