As shown in FIG. 5, the socket housing 3 has a structure in which an electric wire 15 and a female electric connection portion (contact) 2 to which the electric wire 15 is pressed and attached are incorporated. Here, FIG. 5A is a partial plan sectional view of the socket housing 3, FIG. 5B is a front view, and FIG. 5C is a sectional view taken along line cc in FIG. On the other end of the electric wire 15 of the socket housing 3, a pin insertion port 16 into which the pin 6 is inserted is formed. Further, the distal end portion 17 of the electrical connection portion 2 is bent inward so that the elastic force of the distal end portion 17 can reliably contact the inserted pin 6.

Also, on the side surface of the socket housing 3,
A convex portion 10b which is to be engaged with the convex portion 10a formed on the side surface 8a of the receiving portion 8 of the base housing 7 and serves as the lock means 10 is formed.

Next, a state where the socket housing 3 is inserted into the base housing 7 will be described. As described above, the lower surface 12 of the receiving portion 8 of the base housing 7 is formed.
Is open. For this reason, the socket housing 3
Is inserted, the socket housing 3 projects 18 from the lower surface 12 (see FIGS. 2 and 3). The socket housing 3 is positioned and inserted by a guide portion 9 having an uneven shape 11 provided between a side surface of the receiving portion 8 of the base housing 7 and a side surface of the base housing 3 (see FIG. 2).

As described above, the socket housing 3 is securely joined to the base housing 7 while being restrained in the vertical and horizontal directions by the guide portion 9 and the locking means 10 formed between the socket housing 3 and the base housing 7. State. Therefore, even when the lower surface 12 of the receiving portion 8 of the base housing 7 is open, the socket housing 3 is securely held. Thereby, the thickness of the socket housing 3 can be reduced to 3 mm or less, which is half the conventional thickness.

The socket housing 3 is, for example,
As shown in FIG. 6, the side surface of the portion 18 protruding from the base housing 7 may be made convex to form a second guide portion 19 that sandwiches the base housing 7. Thus, by forming the second guide portion 19,
The strength of the socket housing 3 is improved. Further, the vertical movement of the socket housing 3 is more reliably restrained.

Further, in the present embodiment, the connection of the electric connection portion 2 to the electric wire 15 is performed by pressure welding which can reduce the connection portion. For example, the electric connection portion 2 as shown in FIG. Thereby, the connection with the electric wire 15 can be performed by crimping. When the wire 15 is crimped, the crimped portion becomes bulky. However, as shown in FIG. 7, by arranging this crimped portion outside the base housing 7, it is not necessary to increase the thickness of the base housing 7.

The board mounting portion 5 formed on the other end 6b of the pin 6 buried in the base housing 7 of the pin 6 buried in the
It is fixed by the MT method (see FIG. 9). By fixing by the SMT method, it is possible to fix with high dimensional accuracy. As shown in FIGS. 9 and 10, a cutout portion 22 is formed in a portion of the substrate 14 where the socket housing 3 is inserted, and the projection of the socket housing 3 protruding from the receiving portion 8 of the base housing 7. Part 1
8 is to enter. The lower surface of the projecting portion 18 of the socket housing 3 is
0. Further, the upper surface of the upper chassis 21 and the upper surface of the base housing 7 are formed so as to be flush with each other, so that the overall thickness can be about 3 mm. Thus, in a part where the thickness is regulated, it can be used as a board assembly with an electric connector connected to various sensors and the like, an LED lamp unit and the like.

Further, in the present embodiment, an example in which two pins are used has been described. However, the number of pins is not limited to two, and a plurality of pins can be provided.

[0027]

The present invention is configured as described above, and a guide portion having a slidable uneven shape is provided between the side surface of the receiving portion of the socket housing of the base housing and the side surface of the socket housing. Thus, the positioning of the socket housing and the restriction of the vertical, horizontal, and horizontal movements can be performed only by the base housing. As a result, in the base housing having an open lower surface,
Even if the thickness of the socket housing is reduced,
The socket housing can be securely held by the base housing, and can sufficiently withstand the stress applied during connection. Further, by providing the guide portion with the locking means, the socket housing can be securely held. In addition, by providing the second uneven guide portion adjacent to the guide portion, the strength of the base housing can be increased and the holding force of the socket housing can be increased. Further, by using such a thin electric connector, even if a substrate for controlling various sensors and the like is mounted, the thickness can be reduced to less than half of the conventional one. For this reason, it can be used also for a part where the thickness is regulated, and it is possible to cope with miniaturization and thinning of various devices.
