DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground terminal, and more particularly, to a ground terminal provided on a wire harness or the like, and a bolt provided on a ground portion provided at a predetermined portion of a panel of a vehicle body or an electric device. It relates to an attachable ground terminal.

[0002]

2. Description of the Related Art Generally, in a vehicle body or an electric device,
The electrical components are connected to each other by a wire harness, and a part of the wire harness is provided with a ground wire for grounding the electrical component, and a ground terminal provided at an end of the ground wire is provided on a predetermined portion of the panel. It is attached to the grounding part provided at the position.

FIGS. 2 and 3 show a conventional structure for mounting this type of ground wire, for example. 2 and 3, reference numeral 1 denotes a grounding ground wire branched from a wire harness. A grounding terminal 2 provided at an end of the grounding wire 1 is provided with an insertion hole 2a. The bolt 3 is inserted. The bolt 3 is a grounding portion 4 provided at a predetermined position on a panel of a vehicle body or an electric device.
The ground terminal 2 is fixed to the ground portion 4 by screwing the bolt 3 into the screw hole 4a through the insertion hole 2a. ing.

[0004]

However, in such a conventional ground terminal 2, before the bolt 3 is screwed into the screw hole 4a of the grounding portion 4, the bolt 3 is inserted into the insertion hole 2a.
Therefore, there is a problem that the workability of attaching the ground terminal 2 is reduced by the amount of unnecessary work.

Therefore, the present invention makes it possible to improve the workability of the mounting work by unifying the bolt and the bolt through the insertion hole by integrating the ground terminal and the bolt, and to firmly attach the ground terminal to the ground part. It is an object to provide a ground terminal that can be fixed.

[0006]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, a flat mounting portion having a bolt insertion hole through which a bolt screwed to a ground portion provided on a mating member is inserted, and a through hole of the mounting portion is provided. In the ground terminal fixed to the grounding part of the mating member by screwing the bolt to the grounding part, the head of the bolt is located on one side of the mounting part and the other side of the mounting part is By fitting a retaining member having an area larger than the insertion hole to the shaft portion of the positioned bolt, the mounting portion is sandwiched between the head portion of the bolt and the retaining member, and a grounding portion is provided on the other side surface of the mounting portion. And a point-contact or line-contact projection is provided on one side surface of the mounting portion.

In this case, a retaining member having an area larger than the insertion hole of the mounting portion is fitted to a shaft portion of the bolt located on the other side surface of the mounting portion, and the mounting portion is fixed by the head of the bolt and the retaining member. Since it is sandwiched, the bolt can be prevented from coming out of the insertion hole, and can be integrated with the ground terminal. Therefore, the work of inserting the bolt into the insertion hole becomes unnecessary, and the workability of the installation work of the ground terminal can be improved.

In addition, since a projection that makes point or line contact with the grounding portion is provided on the other side surface of the mounting portion, and a projection that makes point or line contact with the head portion is provided on one side surface of the mounting portion, the bolt is attached to the grounding portion. When screwed, the screwing force of the bolt is concentrated on the protrusion, and the mounting portion can be firmly fixed to the grounding portion.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing one embodiment of a ground terminal according to the present invention. First, the configuration will be described. FIG.
In the figure, reference numeral 11 denotes a ground terminal provided at an end of the electric wire 10, and the ground terminal 11 has a bolt 13 screwed to a ground portion 12 provided on a panel (a mating member) of a vehicle body or an electric device. It has a flat mounting portion 14 in which a bolt insertion hole 14a to be inserted is formed.

A ring 13 having a head 13a of the bolt 13 on one side of the mounting portion 14 and a shaft 13b of the bolt 13 on the other side of the mounting portion 14 having a larger area than the insertion hole 14a. A retaining member 15 is fitted into the mounting portion 14 by the head 13a and the retaining member 15.
Is pinched. The retaining member 15 may be made of any of an elastic body and a metal.

A plurality of projections are provided on the other side of the mounting portion 14.
A projection 16 is provided, and the projection 16 comes into point contact with the ground portion 12. Further, a plurality of projections 17 are provided on one side surface of the mounting portion 14, and the projections 16 come into point contact with the head 13a. In this embodiment, the mounting portion is attached to the shaft portion 13b of the bolt 13 located on the other side of the mounting portion 14.
A retaining member having an area larger than the 14 insertion holes 14a
15 and the head 13a of the bolt 13 and the retaining member
Since the mounting portion 14 is sandwiched by 15, the bolt 13 does not come out of the insertion hole 14a, and can be integrated with the ground terminal 11.

When attaching the ground terminal 11 to the grounding portion 12, the shaft portion 13b of the bolt 13 may be screwed into the screw hole 12a of the grounding portion 12, but the bolt shaft portion 13b enters the screw hole 12a. Accordingly, the retaining member 15 moves toward the other side of the mounting member 14, so that the mounting member 14 does not hinder the entry of the shaft portion 13a. In the present embodiment, since the bolt 13 is integrated with the ground terminal 11 in this manner, the work of inserting the bolt 13 into the insertion hole 14a becomes unnecessary, and the workability of the mounting work of the ground terminal 11 can be improved. it can.

Further, a projection 16 is provided on the other side of the mounting portion 14 to make point contact with the grounding portion 12, and a projection 17 is provided on one side of the mounting portion 14 by point contact with the head 13a.
When the screw is screwed into the grounding part 12, the screw 13
It is possible to concentrate on the parts 6 and 17, and the mounting part 14 can be firmly fixed to the ground part. Instead of the projections 16 and 17 that point-contact the grounding portion 12 and the head 13a, the mounting portion 14 may be provided with an annular or linear projection that makes line contact with the grounding portion 12 and the head 13a.

[0014]

According to the first aspect of the present invention, a retaining member having a larger area than the insertion hole of the mounting portion is fitted to the shaft portion of the bolt located on the other side surface of the mounting portion, and the head of the bolt is mounted. Since the mounting portion is sandwiched between the portion and the retaining member, the bolt is prevented from coming out of the insertion hole, and can be integrated with the ground terminal.

[0015] Therefore, the work of inserting the bolt into the insertion hole becomes unnecessary, and the workability of attaching the ground terminal can be improved. In addition, a projection that makes point contact or line contact with the grounding portion is provided on the other side surface of the mounting portion, and a projection that makes point contact or line contact on the head portion is provided on one side surface of the mounting portion. At times, the screwing force of the bolt is concentrated on the projection, and the mounting portion can be firmly fixed to the grounding portion.
