Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to wiring and molded circuit parts (capacitors, diodes, etc.) in automobile electrical circuits.
This relates to the connection to earth (automobile body).

[Prior Art] In Fig. 3, 10 is a wire harness, 12 is an electric wire to be grounded, 14 is a joint connector, and a plurality of contacts 18 are housed in a flat rectangular cylindrical housing 16, and all the contacts are connected to each other. A plate-shaped ground terminal 20 integrally formed with the housing 18 protrudes outward from the housing 16.

An electric wire 12 is connected to each contact 18 via a receptacle 22.

The above ground terminal 20 is connected to the automobile body 26 with a screw 24, and each electric wire 12 is grounded.

Further, 28 is a molded circuit component having a plate-shaped ground terminal 30 protruding from the outside of a rectangular parallelepiped case 38, and the ground terminal 30 is connected to the automobile body 26 with a screw 32 for grounding.

Note that the conventional molded circuit component 28 has a dedicated connector 34.

[Problems to be Solved by the Invention] Since the joint connector 14 and the molded circuit component 28 were grounded separately as described above, two steps were required.

[Means for Solving the Problems] This invention, as shown in FIG. 1, consists of: (1) stacking the case 38 of the molded circuit component 28 on the housing 16 of the joint connector 14 and integrating it; (2) As a means for stacking and integrating; the housing 16 of the joint connector 14
A groove 40 provided on the side surface of the case 38 of the molded circuit component 28 is inserted into the engagement piece 36 provided on the upper surface of the molded circuit component 28.
(3) bend the ground terminal 30 of the molded circuit component 28 so that it overlaps the ground terminal 20 of the joint connector 14, and also connect the screw hole 42 of the ground terminal 20 with the ground terminal 30; The method of matching the position with the screw hole 44 is taken.

[Function] (1) By stacking and integrating the case 38 of the molded circuit component 28 on the housing 16 of the joint connector 14; the space for mounting the components is saved, and the ground terminals 20 and 30 are stacked vertically. Become.

(2) By bending the ground terminal 30 of the molded circuit component 28 and stacking it on top of the ground terminal 20 of the joint connector 14; there is no gap between the ground terminals 20 and 30, making it easier to insert the screw. .

(3) Since the engaging piece 36 provided on the upper surface of the housing 16 of the joint connector 14 is made to engage the groove 40 provided on the side surface of the case 38 of the molded circuit component 28; The molded circuit component 28 no longer rotates around the vertical axis. Therefore, when the two are engaged, the screw hole 42 is automatically
and 44 can be made to match.

[Embodiment] As shown in FIGS. 1 and 2, an engaging piece 36 having an L-shaped cross section is provided on the upper surface of the housing 16 of the joint connector 14.

Also, the mold case 3 of the mold circuit component 28
A groove 40 is provided on the side surface of the joint connector 8, and the groove 40 is engaged with the engagement piece 36, so that the molded circuit component 28 is stacked on the joint connector 14 and integrated.

The ground terminal 30 of the molded circuit component 28 is appropriately bent so as to overlap the ground terminal 20 of the joint connector 14.

The position of the screw hole 44 of the earth terminal 30 is made to match the position of the screw hole 42 of the earth terminal 20.

By doing so, the joint connector 14 and the molded circuit component 28 can be grounded simultaneously using one common screw 46.

In this case, a male connector (not shown) connected to the non-ground electrode of the molded circuit component 28 is built into the mold case 38 of the molded circuit component 28 .

48 is a female connector that fits therein. When fitted, the pawl 50 is engaged with the engagement piece 52 and locked.

[Effects of the invention] (1) Since the case 38 of the molded circuit component 28 is stacked on top of the housing 16 of the joint connector 14 and integrated; the space for installing the components can be saved, and the ground terminal 30 can be placed above the ground terminal 20. It becomes possible to take a position where it is located.

(2) Bend the ground terminal 30 of the molded circuit component 28 and stack it on the ground terminal 20 of the joint connector 14, and insert it into the screw hole 42 of the ground terminal 20.
and the screw hole 44 of the ground terminal 30;
In the process, joint connector 14 and molded circuit component 28 can be grounded simultaneously.

(3) Since the engagement piece 36 with an L-shaped cross section provided on the upper surface of the housing 16 of the joint connector 14 is engaged with the groove 40 provided on the side surface of the case 38 of the molded circuit component 28; After mating, molded circuit component 28 does not rotate about the vertical axis. Therefore, when the two are engaged, the screw holes 42 and 4
4 is automatically aligned and this state is maintained. Therefore, screw fastening work becomes extremely easy.

Further, once tightened, the overlapping ground terminals 20 and 30 do not loosen due to vibrations of the vehicle, and a highly reliable connection can be achieved.

Furthermore, the structure of the ground terminals 20 and 30 is simple, and the structure of the ground terminals 20 and 30 is simple, and the structure of the ground terminals 20 and 30 is simple, and the structure of the ground terminals 20 and 30 is simple, and the structure of the ground terminals 20 and 30 is simple, and the structure of the ground terminals 20 and 30 is simple, and the ground terminals 20 and 30 do not come loose due to vibration even if there is no rotation prevention means necessary for connecting the ground terminals to the vehicle body. Can be done.
