Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grounding terminal having a structure suitable for connecting a grounding circuit included in a wire harness.

[Background of the invention] Some wire harnesses installed in automobiles have a configuration as shown in FIG. 3, for example. That is, this wire harness structure includes a plurality of connectors 1, 1, 1, . . . connected to each unit (not shown).
and the respective branch wire harnesses 2 and ground wires 3 drawn out from these connectors 1, 1, 1, . . . , and these wire harnesses 2 and ground wires 3 are jointed at an intermediate joint 4 and bundled. It consists of a trunk wire harness 5, and a ground terminal 6 is attached to the tip of the ground wire 3. Therefore, in this conventional example, since the intermediate joints 4 are provided at several locations on the main wire harness 5, the insulation that protects the intermediate joints 4 due to extreme bending or compression of this wire harness, etc. There was a risk that the tape (not shown) would tear, resulting in a short circuit between the circuits. Furthermore, the presence of a large number of intermediate joints 4 causes problems such as poor workability in manufacturing the wire harness and also requiring time and effort to shape the wire harness.

In order to solve this problem, a wire harness as shown in FIG. 4, for example, has been proposed. This wire harness bundles the branch wire harnesses 2 connected to each connector 1 so that no intermediate joint is provided in the main wire harness 5, and also connects the ground wires 3 in these branch wire harnesses 2 to each other. When pulling out the ground terminals 6 attached to the tips (pulled-out ends) of the ground wires 3 and screwing them onto the vehicle body, for example, connect the ground terminals 6 by overlapping them as shown in Fig. 5. Some have made it so. However, with such a connection means for each ground wire 3, it takes time and effort to overlap and tighten the two ground terminals 6, and there are also problems such as forgetting to tighten one of the ground terminals 6. (Refer to Utility Model Application No. 55-65774).

Therefore, before attaching the two ground terminals 6 to the vehicle body, etc., in order to ensure that the two ground terminals 6 are connected together, as shown in Fig. 6A,
One of the ground wires 3 has raised locking claws 6a, 6 at two places on the left and right sides of a through hole 6c provided in the center thereof.
A ground terminal 6 is attached to the other ground wire 3, and a ground terminal 6 is attached to the other ground wire 3, which has locking claws 6d and 6e at two locations on the left and right sides of a through hole 6c provided in the center thereof. , the ground terminals 6, 6 are placed one on top of the other as shown in FIG. 6 is placed in the through hole 6c of one of the ground terminals 6, and the two ground terminals 6 and 6 are overlapped, then the locking claws 6d and 6e of one ground terminal 6 are By sliding so as to be joined to the upper surfaces of the locking claws 6a and 6b of the ground terminal 6, both the ground terminals 6 and 6 are held together in an overlapping manner. A mounting screw is inserted into the through hole 6c of the two earth terminals 6, 6 which are superimposed and held in this way, and is screwed to the vehicle body, etc. According to the ground terminal of this structure, the mounting screw can be used to tighten the mounting screw. Due to the torque at the time, the locking claws 6a, 6b, 6
There was a problem that d and 6e were deformed, making it impossible to separate the ground terminals of both of them or to reuse them.

[Purpose of the invention] The present invention was made by focusing on the problems of the conventional method, and is an improvement of a type of earth terminal that is attached to a vehicle body etc. by stacking two earth terminals.
It is possible to easily and reliably maintain the overlapping of both ground terminals, and there is no deformation even when tightening torque is applied using the mounting screws.
The object of the present invention is to provide a grounding terminal in which separation and repolymerization of both grounding terminals can be repeated.

[Summary of the invention] As described above, the invention consists of two terminal boards each having a crimping part where the electric wire is crimped and a terminal board part each having a through hole for inserting a mounting screw. One side of the terminal plate part of the terminal plate 11 is folded back onto the terminal plate part to form a folded piece, and one side of the terminal plate part of the other terminal plate is inserted into the gap between the folded piece and the terminal plate part. The grounding terminal is characterized in that the side edge portions are fitted, locking portions that are locked to each other are provided in the fitting portions, and both terminal plates are overlapped so that the through holes communicate with each other. .

[Embodiments of the invention] The invention will be described in detail below based on the embodiments shown in FIGS. 1 and 2.

Reference numerals 11 and 12 are ground terminal plates connected to the respective ground wires 13, and one of the ground terminal plates 11 has a crimping portion 11a with the ground wire 13 and a tightening screw (not shown) inserted therethrough. Through hole 11b for
A terminal plate portion 11c having a hole therein, a folded piece 11d folded back in a U-shape from one side end of the terminal plate portion 11c, and a terminal plate portion 11d provided on the folded piece 11d.
It has two locking holes 11e. The other ground terminal plate 12 includes a terminal plate portion 12c having a crimped portion 12a with the ground wire 13 and a through hole 12b for inserting a tightening screw, and the terminal plate portion 12c.
The locking hole 1 is provided near one side end of 2c.
It has two locking holes 12d corresponding to 1e.

In this way, in this embodiment, the ground terminal plate 11 and the
2, and both ground terminal plates 11 and 12
To combine them together, one ground terminal plate 11
The terminal plate part 12c of the other ground terminal plate 12 is positioned so that it overlaps the terminal plate part 11c of the ground terminal plate 11, and then the edge of the other ground terminal 12 is inserted into the folded piece 11d of one ground terminal plate 11. , by locking the locking claw 12d into the locking hole 11e, both the ground terminal plates 11 and 12 are connected to the second
As shown in the figure, the through holes 11b and 12b formed in both the terminal plate parts 11c and 12c are also aligned and integrated into one body. The through holes 11b and 12b of the ground terminal plates 11 and 12 thus combined
By passing a mounting screw inside the connector and fastening it to a predetermined position on the vehicle body, both ground wires 13 are simultaneously and reliably connected to the ground.

As described above, according to the ground terminal structure according to this embodiment, since a pair of ground terminal plates are superimposed and held vertically with one touch, it is extremely advantageous to fasten the ground terminal plates at the same time. Since the parts to be fastened by the mounting screws are the flattened terminal plate parts 11c and 12c, even if the clamping force by the mounting screws acts on these ground terminal plates, they will not be deformed, and the ground terminal plates on both sides will not be deformed. It has the advantage that it can be used any number of times without any trouble in separating and recombining it. Furthermore, these ground terminal plates have respective through holes 11 in the terminal plate parts 11c and 12c.
Since the holes b and 12b are drilled, these ground terminal plates can be screwed together in a predetermined position, which has the effect of providing a highly practical ground terminal.

[Effects of the invention] Therefore, according to this grounding terminal, two terminal boards are superimposed and held vertically with one touch, so it is extremely advantageous to fasten the terminal boards at the same time. Since the tightening part of the plate with the mounting screws is flattened, the tightening force of the mounting screws will not deform the terminal boards, and both terminal boards can be separated and reassembled again and again without any trouble. There are effects that can be used. Furthermore, these terminal boards have through-holes 12b formed in the terminal board parts 11c and 12c, so that these terminal boards 1
1 and 12 can also be screwed alone into a predetermined position, which has the effect of providing a grounding terminal with excellent practicality.
