DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 denotes a coupler direct connection type valve socket (hereinafter abbreviated as valve socket 1) according to the present invention. The valve socket 1 includes a valve insertion portion 21 and a coupler insertion portion 22. Inside the socket body 2 made of a resin member or the like formed in a substantially L-shape, the terminal 3 similarly formed of a metal member in a substantially L-shape by the valve terminal portion 31 and the coupler terminal portion 32 is housed. It is the same as that of the conventional example.

First, the terminal 3 will be described. The valve terminal portion 31 and the coupler terminal portion 32 of the terminal 3 are integrally formed from a single plate member by pressing or the like. The valve terminal portion 31 and the coupler terminal portion 32 are arranged so as to be substantially at right angles, and are formed so as to have a generally L-shaped shape as a whole.

At this time, the contact piece 31 having a shape suitable for contacting the base 81 of the wedge base light bulb 80 from both side surfaces along the longitudinal direction of the valve terminal portion 31.
a, the contact piece 31b has a substantially U-shaped cross section (or an inverted U-shaped)
And the contact piece 31a and the contact piece 31 are provided.
The base 81 is clamped and held by b and is electrically connected.

The coupler terminal portion 32 is formed into a shape that fits into a receiving terminal provided on the vehicle body side coupler 90 inserted into the coupler insertion portion 22, that is, formed as a male terminal shape. However, at this time, in the vicinity of the portion where the valve terminal portion 31 is joined, there is a step difference such that the valve terminal portion 31 side is the outer side when the socket body 2 is assembled. The part 33 is provided.

It is to be noted that the above-mentioned terminal 3 requires a left and right pair, and at this time, the above-mentioned pair has a line-symmetrical shape and is not the same on the left and right sides. Bending of the piece 31a and the contact piece 31b, and the step portion 3
It is possible to form from the same blanking by performing the bending of No. 3 in reverse.

On the other hand, the socket body 2 has a valve insertion port 2
1a is provided in the valve insertion portion 21 and the coupler insertion port 2
The coupler insertion portion 22 provided with 2a is arranged at a substantially right angle to form a substantially L shape. At this time, according to the present invention, the position to be the back surface of the valve insertion port 21a is formed. Is provided with a terminal insertion hole 23,
In addition, hook portions 24 are provided on the left and right side surfaces of the valve insertion portion 21.

The terminal insertion hole 23 arranges the valve terminal portion 31 at a predetermined position of the valve insertion portion 21, and
The coupler terminal portion 32 is also formed so as to be arranged at a predetermined position of the coupler insertion portion 22, and therefore, the valve insertion portion 21 is provided with a corner in consideration of the shape and size of the valve terminal portion 31. A through-hole portion 23a having a hole shape is provided to suppress excessive movement of the valve terminal portion 31 in a direction other than the insertion direction, and further, the stopper portion 2 is provided on the distal end side in the insertion direction.
3b is provided to prevent the insertion of more than the specified amount.

Further, with respect to the coupler terminal portion 32, a slit groove 23c is provided in a partition wall 22b which is provided in the coupler insertion portion 22 to give a stop position to the vehicle body side coupler 90, whereby the coupler insertion portion 22 is provided. Is to be given a predetermined interval. Therefore, by inserting the terminal 3 into the terminal insertion hole 23, the terminal 3 is set at a predetermined position in the socket body 2.

The hook portion 24 is provided for locking the terminal 3 set at a predetermined position by the terminal insertion hole 23 as described above, and the hook portion 24 is provided on the side surface of the socket body 2 in a substantial shape. The U-shaped slit includes a spring portion 24a having a free end at the insertion direction side of the terminal 3, that is, the rear end of the socket body 2, and a claw portion 24b provided at the front end of the spring portion 24a. The claw portion 24b is formed in a position and shape to engage with the stepped portion 33 of the terminal 3.

Therefore, in the process of inserting the terminal 3 into the terminal insertion hole 23, the claw portion 24b does not evade the insertion of the spring portion 24a due to the bending of the spring portion 24a, but the terminal 3 is inserted to a predetermined position. At some times, the claw portion 24b is returned to its original position by the elasticity of the spring portion 24a and is hooked on the step portion 33. Therefore, the terminal 3 is inserted into the stopper portion 2 toward the insertion direction side.
3b, and the claw portion 24b is locked to the socket body 2 toward the extraction direction.

[0016]

As described above, according to the present invention, the stepped portion is provided in the vicinity of the connection between the valve terminal portion and the coupler terminal portion of the terminal so that the valve terminal portion side is the outer side with respect to the socket body. And a terminal insertion hole for locking the movement of the child in a direction orthogonal to the insertion direction is formed at a position which is a back surface of the valve insertion portion of the socket body, and a side surface corresponding to the valve terminal portion of the valve insertion portion. The connector is a coupler direct connection type valve socket that is provided with a flexible hook part that engages with the step part, so that the terminal part does not fall off with the hook part when inserting the light bulb and the stopper part when removing the bulb. As a preventive measure, it can be held securely, and
By providing the terminal insertion hole on the back side of the bulb insertion portion, it is possible to surely attach the bulb insertion portion to a lamp without needing to provide a terminal insertion opening in the bulb insertion portion. It is extremely effective in improving the reliability of the direct connection type valve socket.
