Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a grounding joint connector used in the engine compartment of an automobile.

``Prior art'' and ``problems to be solved by the invention'' The conventional joint connector described above was
As described in Japanese Patent No. 112778, as shown in FIG. A joint terminal with a part bent backward to form a grounding bracket part 6 is used, and the board 8 and tab-shaped contact part 3 are housed in a male housing (not shown), and the bracket part 6 is exposed to attach to the vehicle body. It has a structure in which it is bolted and fixed at key points, and a female housing containing an electric wire to be grounded is connected to the male housing for grounding.

According to the above conventional structure, the tab-shaped contact portion 3 of the joint terminal and the bracket portion 6 are both formed by bending the common edge of the board 8 forward and backward, so that the base of the bracket portion 6 has a The tab-shaped contact portion 3' shown by the dotted line in the figure becomes impossible to form.
There is a drawback that only that part is missing, reducing the number of contact parts that can be connected to the ground.

On the other hand, in order to solve the above-mentioned difficulties, there is a known example in which a bracket portion 6 is formed on the side edge of the substrate 8 as shown in FIG. However, according to this known example, the position of the bracket portion 6 is limited to only the left and right side portions of the terminal, and there is a problem that it may not be possible to attach it depending on the circumstances of the vehicle body.

The purpose of the present invention is to solve the above-mentioned conventional difficulties.

``Means for Solving the Problems'' The present invention, which achieves the above objectives, ``has a connection part made of a single plate bent into a rectangle, and a tab-shaped contact part is arranged in parallel at the front edge of the connection part. a joint terminal that protrudes from the connector housing and has a grounding bracket formed on the rear edge of the joint, and the tab-shaped contact part and the connecting part of the joint terminal are housed and locked in a male connector housing. It is completed.

"Example" and "Operation" Hereinafter, it will be explained in detail by referring to an example. Referring to FIG. 1 showing an embodiment thereof, the earthing joint connector of the present invention has a joint terminal 2 housed and locked in a male connector housing 1 (hereinafter simply referred to as male housing 1). The tab-shaped contact portion 3 of the joint terminal 2 protrudes into the front recess 4 of the male housing 1, and the grounding bracket portion 6 of the joint terminal 2 is exposed at the rear, so that the bracket portion 6 can be bolted to key points on the vehicle body. The male housing 1 is fixedly attached to the vehicle body, and a female housing (not shown) containing a female terminal of an electric wire to be grounded is connected to the recess 4, so that a group of electric wires to be grounded are collectively grounded. It has become.

Specifically, the joint terminal 2 is made by bending a single plate material into a horizontal rectangular shape as shown in FIG. In the portion 5', tab-shaped contact portions 3 cut out from the same plate material as the connecting portion 5 are provided in two rows, upper and lower, and protrude forward from the front edge portion 5'.
The lower plate material of the rear edge 5'' of the connecting portion 5 extends rearward and is bent into a stepped shape to form a grounding bracket portion 6, at the tip of which a bolt hole 7 for mounting to the vehicle body is drilled. It has been done.

When the above-mentioned joint terminal 2 is housed in the male housing 1, a locking hole 10 is provided at the base of the tab-shaped contact portion 3 for locking the housing posture, and an elastic locking hole 10 is provided at the base of the tab-shaped contact portion 3. It is configured to engage with the tip of the stopper piece 9. (In this example, with the intention of adjusting the insertion resistance of the joint terminal,
There are locking holes 1 in only three of the six tab-shaped contact parts 3.
A lattice-shaped rib is formed on the inside of the male housing 1, and the rib is connected to the tab-shaped contact portion 3.
the adjacent gap or the slit 1 at the bent end of the connecting part 5
1 and the hollow part of the connecting part 5, the joint terminal 2 is housed in the male housing 1 without any play, and by the locking mechanism of the elastic locking piece 9 and the locking hole 10, It is designed to be locked in place without being easily pulled out.

Next, FIG. 2 shows a joint terminal 2 according to another embodiment of the present invention, in which the number of bends of the plate material when forming the connecting portion 5 is reduced to facilitate processing. It is formed by an upper plate part, a lower plate part, and a side plate part on one side that connects the upper plate part and the lower plate part.

According to the earthing joint connector of the present invention, the tab-shaped contact portion group 3 of the joint terminal 2 and the earthing bracket portion 6 are connected to the front edge 5' of the connecting portion 5.
Since the tab-shaped contact portion 3 and the grounding bracket portion 6 can each independently utilize the front and rear edges of a single plate,
The required number of tab-shaped contact portions 3 for ground connection can be formed at the required positions, so that they will not be missing as in the conventional case, and the total number of poles of the male housing 1 can be effectively utilized.

The grounding bracket part 6 can also be formed in any position of the connecting part 5, in any shape, and in any direction depending on the installation circumstances of the vehicle body, so the degree of freedom in its design is improved and It becomes possible to design the grounding bracket part 6 with priority given to

Furthermore, by increasing the degree of freedom in designing the grounding bracket part 6, it becomes possible to provide sufficient mechanical strength to the grounding bracket part 6, thereby making it possible to further stabilize the bracket function.

"Effects of the Invention" As described above, the grounding joint connector of the present invention improves the degree of freedom in designing the joint terminal contact part and the bracket part, increases the number of effective poles of the connector housing, and improves the grounding joint connector. This has the effect of further improving terminal installation and stability.
