Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small-sized lamp socket connector that integrates a receiving terminal for lamp connection and a terminal for connector connection.

[Prior Art] When using a small insertion lamp for illuminating a vehicle, etc., conventionally, as shown in FIG. 4, for example, a lamp holder 2 to which an insertion lamp 1 is attached and a connector 3 are separated. In some cases, an electric wire 4 is used to connect the two. The lamp holder 2 has two built-in receiving terminals for inserting the insertion lamp 1, and the connector 3 has two built-in flat blade terminals for connecting with the connection terminal of the mating connector. has been done. An electric wire 4 connecting the lamp holder 2 and the connector 3 has one end connected to a receiving terminal and the other end connected to an insertion flat blade terminal.

This conventional device has a problem in that it has a large number of component parts and requires a large number of assembly steps. Furthermore, although the lamp holder 2 is fixed to the chassis of the vehicle, it is unstable because the connector 3 is not fixed, and the connector 3 may come into contact with other parts due to vibration, causing a banging noise or malfunction. There are cases.

Furthermore, as disclosed in Japanese Utility Model Application Publication No. 58-17788, a lamp socket is also known in which a lamp holder made of a soft material that holds the lamp and a socket main body are combined to omit the electric wire. In this case, since the terminal member in contact with the conductive part of the lamp is used as the insertion terminal of the connector, the terminal member has disadvantages such as poor stability and easy contact with the lamp.

[Purpose of the invention] The purpose of the invention is to improve the above-mentioned conventional device,
It is an object of the present invention to provide a reliable lamp socket connector which is small in size, has a reduced number of parts and manufacturing process, integrates a socket and a connector, and has good locking of an insertion terminal.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
A lamp holder to which the lamp is attached; a pair of flat-blade insertion terminals having their bases fixed to the lamp holder; and a substantially box-shaped body connected to the lamp holder and covering the insertion portion of the insertion terminals. and a flat plate portion provided adjacent to the connection portion of the bifurcated insertion terminal that clamps the conductive portion of the lamp, and a spring claw portion is formed for locking in the lamp holder. The insertion of the cover is stopped at a predetermined position with a locking piece that locks on the protrusion and engages with the cover at the base of the insertion portion of the insertion terminal inserted into the cover, and to join the cover,
The lamp socket connector is characterized in that arm portions having substantially T-shaped tips protrude from both sides of the cover and are fitted into receiving portions of the same shape of the lamp holder.

[Embodiments of the invention] The invention will be explained in detail based on the embodiments shown in FIGS. 1 to 3.

In FIG. 1, 10 is a lamp, 11 is a lamp holder, 12a and 12b are connection terminals, and 13 is a cover. The lamp holder 11 and cover 13 are molded from synthetic resin having electrical insulation properties.
The connection terminals 12a, 12b are made by punching and molding a conductive metal plate.

The lamp holder 11 can fix the lamp 10, and is provided with two terminal receiving holes 14 for inserting connection terminals 12a and 12b from opposite sides of the lamp 10, as shown in FIG. A locking protrusion 15 projects inward from the holder.
Further, covers 13 are provided on both sides of the lamp holder 11.
A notched connecting portion 16 for locking is provided.

The connection terminals 12a and 12b are each provided with a flat blade-like insertion portion 17 and a bifurcated elastic connection portion 18 for sandwiching the conductive portion of the lamp 10, and a portion adjacent to these connection portions 18 is provided. A flat plate part 19 is provided, and the lamp holder 11 is mounted on this flat plate part 19.
A claw portion 20 having spring properties is formed to be engaged with the engagement protrusion 15 . In addition, the insertion part 17
When inserted into the cover 13, the base of the
A locking piece 2 for stopping this insertion at a predetermined position and engaging with a projection (not shown) of the connector 13
1 is formed.

As shown in FIG. 2, the cover 13 has a substantially box-like shape with an opening on one side for fitting a mating connector and a space 22 inside, and has connection terminals 12a and 12b respectively. Long holes 23a and 23b for insertion are formed at the rear. Also,
In order to fit into the lamp holder 11, an arm portion 24 having a substantially T-shape that fits into the connecting portion 16 of the lamp holder 11 projects rearward.

When assembling this lamp socket connector, for example, by inserting the connecting terminals 12a and 12b into the lamp socket 11, the connecting terminals 12
The claw portions 20 of a and 12b are locked to the locking protrusions 15 of the lamp holder 11 and fixed so that they cannot be pulled out.
Furthermore, the insertion portions 17 of the connection terminals 12a and 12b are inserted into the elongated holes 23a and 23b of the cover 13, and the locking pieces 21 engage the protrusions (not shown) of the connector 13, and the arm portions 24 of the cover 13 are inserted. By fitting into the connecting portion 16 of the lamp holder 11 while opening, the lamp holder 11, the connection terminal 12a,
12b and the cover 13 are assembled together. At this time, the lamp holder 11 and the cover 13 are
4, and the connecting terminal 12
They will be indirectly connected via a and 12b.

After this assembly is completed, when the lamp 10 is fitted into the lamp holder 11, the conductive part of the lamp 10 is connected to the connection terminal 12a,
It will be inserted into the connecting part 18 of 12b.

FIG. 3 shows another embodiment, in which connection terminals 12a,
Each insertion portion 17 of 12b is bent in an L-shape and faces upward, unlike the case shown in FIG. The cover 13 is provided with notches 25a and 25b through which the insertion portion 17 can pass, and the opening for fitting with a mating connector is directed upward. In this case as well, the lamp holder 11, the connection terminals 12a, 12b,
The cover 13 can be assembled in one piece.

[Effects of the invention] As explained above, according to the lamp socket connector of the invention, the electric wire between the lamp holder and the connector, which has been traditionally used for a long time, is omitted, resulting in an extremely simple structure, and There are advantages in that the number of points and manufacturing steps are reduced, accidents caused by poor connections with electric wires or instability of connectors are almost eliminated, and reliability is improved.
