Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grounding terminal,
In particular, it relates to a grounding terminal suitable for fixing a plurality of grounding terminals at the same position.

[0002]

2. Description of the Related Art Generally, a wire harness for an automobile or the like is provided with a grounding electric wire extending from the wire harness. A grounding terminal is provided at one end of the electric wire and the grounding terminal is used for a vehicle. A structure is known in which it is fixed to a body through appropriate bolts.

FIG. 4 shows an example of a conventional ground terminal fixing structure in an automobile. In this figure,
A wire harness 31 is wired in the hood of the vehicle 30. The grounding electric wire 32 housed in the wire harness 31 is extended from one end or the middle of the wire harness 31 to the outside, and one end thereof is fixed to the vehicle 30 portion in the bonnet. It is designed to be grounded.

More specifically, as shown in FIG. 5, a ring-shaped grounding terminal 34 having a bolt insertion hole 33 is connected to one end of an electric wire 32 for grounding. The bolt 35 is inserted into the hole 33 so that the tip end side of the bolt 35 is a screw hole 36 formed in the vehicle 30 portion.
Screwed to the vehicle 30 of the grounding terminal 34.
It is designed to be fixed to the side.

By the way, in automobiles and the like, grounding is often performed at the same position. Therefore, in this case,
As shown in FIG. 6, the grounding terminals 34 having substantially the same shape are superposed on each other, and the bolts 35 are inserted into the respective bolt insertion holes 33 and screwed into the screw holes 36 to be fixed to the vehicle 30 portion. Becomes According to this, the grounding positions can be integrated, and the fixing work can be unified by reducing the number of bolts.

[0006]

However, in the above-mentioned conventional structure, when a plurality of grounding terminals 34 are superposed, the wall thicknesses of the respective grounding terminals 34 are inevitably integrated. However, there is an inconvenience that it is unsuitable when the entire length of the bolt 35 or the length of the thread forming region is limited. This has also become a factor that makes the work difficult when grounding is required in an extremely narrow space.

In addition, one earth circuit is removed,
Alternatively, when reattaching, it is necessary to attach and detach the bolts 35 fixing the respective grounding terminals 34 each time. As a result, not only does the work become complicated, but also the surface of the grounding terminal 34 is It was also supposed to increase the incidence of damage such as easy scratching.

Further, in the conventional grounding terminal 34, if a plurality of terminals are tightened together, slack is likely to occur, and bending of each grounding terminal 34 is likely to occur during bolt tightening.
There was also the inconvenience of impairing reliability.

Further, when a plurality of ground terminals 34 are extended from a single wire harness, it does not cause a problem so much, but the ground terminals 34 extended from different wire harnesses at the same location. In the case of fixing, the fixing work cannot be performed until the wiring of all the grounding terminals 34 is completed, and there is also a disadvantage that the assembly process in the production line work of the automobile or the like has a certain limitation.

[0010]

It is an object of the present invention to improve the disadvantages of the conventional example, and in particular, when fixing a plurality of ground terminals at the same location, one ground terminal is fixed and different ground terminals are provided. It is an object of the present invention to provide a grounding terminal that can be connected to the terminal for use at any time.

[0011]

According to the present invention, in a grounding terminal having a bolt insertion hole formed in a plate-like piece fixed to one end of an electric wire, an outer edge of the plate-like piece is continuous with the plate-like piece. At least one connecting piece is provided, and different grounding terminals are provided so as to be connectable to this connecting piece.

[0012]

When fixing the grounding terminal, the plate-like piece is positioned on the fixed portion and the bolt is inserted into the bolt insertion hole for tightening and fixing. Since the earthing terminal thus fixed is provided with the connecting piece, when additionally fixing the other earthing terminal, the earthing terminal can be connected to this connecting piece at the same position. Can be grounded.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the external configuration of this embodiment. In this figure, a grounding terminal 1 fixed to a body of a vehicle or the like is connected to one end of a grounding electric wire 2 extending from a wire harness (not shown).

The grounding terminal 1 has a plate-like piece 3 having a substantially ring shape and a bolt insertion hole 4 formed in the center thereof, and a connecting portion 5 of an electric wire 2 formed on an outer edge portion of the plate-like piece 3. And a connecting piece 6 provided at an outer edge portion on the opposite side to the connecting portion 4.

The connecting piece 6 is provided so that both sides thereof are continuous with both sides of the plate-like piece 3, and in this embodiment, it is formed with a constant inclination angle with respect to the surface of the plate-like piece 3. There is. A tip portion 6B of the connecting piece 6 is narrowly formed via a step portion 6A, and another grounding terminal 10 is connected to the tip portion 6B. At this time, the other grounding terminal 10 is connected to the tip portion 6 of the connecting piece 6.
A slit 11 is formed so that it can be fitted into B.

In the above structure, the grounding terminal 1 can be fixed to a fixed portion such as a vehicle body by inserting a bolt (not shown) into the bolt insertion hole 4 and tightening the bolt. .

The earthing terminal 1 fixed in this way
When fixing the other grounding terminal 10 to the above, the tip portion 6B of the connecting piece 6 and the slit 11 formed in the other grounding terminal 10 may be fitted to each other.

Therefore, according to such an embodiment, when fixing the plurality of grounding terminals 1 and 10, only the grounding terminal 1 is fixed by bolts to connect the other grounding terminals 10. Since it is possible to do so, there is no need to superpose the grounding terminal as in the conventional case, and this has the effect that even if the bolt length is limited, it can be coped with without difficulty.

Further, since there is only one ground terminal fixed by the bolt, it is effective that the surface of the terminal is damaged by the rotational force applied to the terminal when tightening the bolt, the friction between the terminals and the like. Can be reduced to

Further, when the grounding terminals extending from different wire harnesses are fixed at the same location, even if the work for fixing the grounding terminals 1 fixed by bolts is preceded, another grounding is performed. Since the use terminals 10 can be connected after that, there is an effect that the work with less restrictions can be performed in each process although it is a line work such as automobile assembly.

Further, according to this embodiment, there is no need to loosen the bolt when it is necessary to remove or replace the other earthing terminal 10 connected to the connecting piece 6, From this point as well, there is little risk of damaging the surfaces of the grounding terminals 1 and 10, and the work such as replacement can be performed very easily and quickly, and especially when the grounding is performed in an extremely narrow area, Such an effect becomes more remarkable.

In the above embodiment, the connecting piece 6 is the electric wire 2.
Although the example of being located on the side opposite to the connecting portion 5 has been shown and described, the present invention is not limited to this, and may be provided at a position 90 degrees apart from the connecting portion 5 as shown in FIG. 2, for example. ,
Further, the connecting piece 6 may be provided in two pieces or more as shown in FIG. According to this
In addition to the effects described above, it is possible to add an effect that more ground terminals can be integrated.

Furthermore, the connecting piece 6 does not have to be inclined with respect to the plate-like piece 3, and its shape is not limited to the illustrated configuration example, either.
It is possible to adopt various shapes. In short, the connecting piece 6 in the present invention is determined by the correlation with the shape of another grounding terminal that fits or engages with the connecting piece 6.
