Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to terminals for bulb sockets used in automotive lighting equipment, etc., and more specifically, to terminals for bulb sockets that are directly connected to power supply side connectors. This relates to the terminal connected to the anode side of the bulb.

[Prior Art] Since this type of valve socket terminal is integrated into a small socket main body, it is limited by the thickness of the metal piece constituting the terminal and the installation space. For this reason, with conventional terminals of this type, it is not possible to impart sufficient springiness to the contact that comes into contact with the anode side of the bulb, and as a result, the contact tends to wear out with use, resulting in poor contact with the bulb. There was a problem that could easily cause this.

On the other hand, using a metal piece with high spring characteristics will increase the material cost and make it difficult to mold, and using a coil spring will improve the spring characteristics, but you will need to connect a separate metal piece to connect the connector. This results in a problem of increased processing costs, and the current situation is that a satisfactory terminal has not yet been provided.

[Problem to be solved by the invention] This invention was made in view of the current situation, and it is possible to create a contactor that comes into contact with the anode side of the valve without using a metal piece with particularly high spring characteristics. It is possible to impart good springiness, eliminating the risk of the contact sagging over a long period of time, and the connector to be connected to the connector can be formed in one piece without connecting a separate metal piece. To provide a terminal for a valve socket at low cost, which is simple and easy to assemble to a socket body.

[Means for Solving the Problems] The valve socket terminal of the present invention that achieves the above purpose includes a contact made by bending a single piece of metal and which comes into elastic contact with the anode side of the valve, and a connector that is connected to the connector. and the contactor is formed into the same body, and the contactor is curved in opposite directions at its base and center to form a substantially question mark shape.

[Example] Hereinafter, an example of implementing the present invention will be described based on the drawings.

A in the figure shows the valve insertion port 3 made of synthetic resin material.
and a connector insertion opening 4 are integrally molded, and the anode side B ₁ of the valve B is inserted between the valve insertion opening 3 and the connector insertion opening 4 inside the socket body.
Terminal C in electrical contact with the cathode side of bulb B
A valve socket is constructed by integrally assembling B ₂ and a grounding terminal D that makes electrical contact. Then, insert and attach valve B to the valve insertion port 3 side,
A power supply side connector (not shown) is inserted and connected to the connector insertion opening 4 side, and the bulb B and the connector are electrically connected to each other via the terminal C and the grounding terminal D.

The terminal C is formed by bending a single metal piece to form a contact 1 that comes into elastic contact with the anode side _B1 of the bulb B and a connector 2 that is connected to the connector into the same body.
That is, using one thin strip-shaped metal piece, one end thereof is used as a contact 1 and the other end is used as a connector 2, and the contact 1 has a base portion (connector 2 side) 1b and a central portion 1a.
are bent in opposite directions to form a base bent portion 1b.
and the central bent portion 1a are formed into a substantially question mark shape (approximately ? shape) capable of imparting double springiness, and the connector 2 is bent at a substantially right angle to the contactor 1 along the longitudinal direction, On the upper side (contact member 1 side), a retaining locking piece 5 which is elastically locked in the locking groove 12 of the socket main body A is cut and formed in a protruding manner. When assembling this terminal C into the socket body A, the connector 2 is inserted from the valve insertion port 3 side of the socket body A, and the connector 2 is inserted into the insertion hole formed in the internal bottom wall 13 of the socket body A. The connector is made to penetrate and protrude from the hole 14 into the connector insertion opening 4. Then, the locking piece 5 protruding from the upper side of the connector 2 (on the contactor 1 side) is elastically locked in the locking groove 12 of the socket body A, and the contactor 1 is inserted into the valve insertion port 3. Terminal C is installed at the center position, and the assembly of terminal C is completed.

On the other hand, the grounding terminal D is made by bending a single strip-shaped metal piece to form a contact 6 that contacts the cathode side _B2 of the bulb B and a connector 7 that is connected to the connector into one body. It becomes. That is, one end of a strip-shaped metal piece is used as the contact 6, the other end is used as the connector 2, and the cathode side of the bulb B is placed on the contact 6 side.
A protruding elastic piece 9 that makes direct electrical contact with B ₂ and an anti-rattling piece 11 that engages in the mounting groove 8 of the socket body A are protruded to form a protruding elastic piece 9 between the connector 7 and the contact 6. It is constructed by protruding a retaining piece 10 that is elastically locked into a locking groove 12 of the main body A. When assembling this grounding terminal D into the socket main body A, the connector 7 is inserted from the valve insertion port 3 side of the socket main body A, and the connector 7 is inserted through the insertion hole 14 of the socket main body A into the connector insertion port. 4, and the contact 6 is inserted into and engaged with the mounting groove 8 of the socket body A. Then, the retaining locking piece 10 is elastically locked in the locking groove 12 of the socket body A, and the rattling prevention piece 11 of the contact 6 is inserted and engaged in the mounting groove 8 of the socket body A, and the grounding The assembly of terminal D is completed.

[Effects of the invention] In this way, the valve socket terminal of the present invention is made by bending a single piece of metal to form a contact element that comes into elastic contact with the anode side of the valve and a connector that is connected to the connector into the same body. In addition, since the contactor is bent in opposite directions at its base and center portion to form a substantially question mark shape, the contactor is given double springiness at the base bending portion and the center bending portion. Therefore, it is possible to provide sufficient springiness to the entire contact without using a metal piece with exceptionally high springiness, and as a result, there is no risk of the contact becoming sagging over a long period of time. The reliability of the electrical connection with the valve can be maintained throughout the period.

Moreover, since the connector to be connected to the connector can be formed integrally with the contact without connecting a separate metal piece, the terminal can be easily molded and assembled into the socket body, resulting in overall cost reduction. It is possible to expect.

Therefore, the intended purpose can be achieved.
