Description

[Detailed Description of the Invention] This invention relates to a compact fluorescent lamp socket. Conventionally, Japanese Utility Model Publication No. 50-10700 discloses a fluorescent lamp socket as shown in FIG. As shown in the publication, this fluorescent lamp socket has the free end of a conductive plate 2 installed inside the socket body 1 in contact with the back surface of the receiver 3, and the free end of the conductive plate 2 and the socket. A compression spring 4 was installed between the inside of the main body 1 and the back surface, and this compression spring 4 provided a force for holding the fluorescent lamp. Although such a fluorescent lamp socket can be made smaller because it utilizes the compression spring 4, on the other hand,
In order to incorporate the compression spring 4, the socket body 1 is
After the compression spring 4 was assembled, it was necessary to fasten the two molded products together. Therefore, there are disadvantages in that the number of parts is large and assembly is not easy, and furthermore, the compression springs 4 become entangled with each other during assembly, making handling difficult.

In order to solve this drawback caused by the compression spring 4, a leaf spring may be used. As an example of using a leaf spring, the one shown in FIG. 2 is used in Japanese Utility Model Publication No. 43-23338. In this fluorescent lamp socket, a substantially circular receiver 3 is inserted into an insertion hole 5 of a socket main body 1 having an insertion hole 5 on the front surface, and a strip-shaped contact spring body 6 is housed inside the receiver 3.
In such a fluorescent lamp socket, since the strip-shaped contact spring body 6 is used, the socket main body 1 can be composed of one member, the number of parts is small, and assembly is easy. Since the socket 3 is housed in the approximately circular socket 3, the socket 3 becomes large, and as a result, it becomes difficult to push the fluorescent lamp into the socket main body 1 when inserting or removing the fluorescent lamp. The drawback was that it could only be applied to physical objects.

This device is equipped with a receiver that is approximately box-shaped with an open back and a substantially rectangular lower part, and this receiver has a spring body storage section that communicates with a pin insertion hole and has a roughly rectangular lower part on the back side. Further, the lower side wall of the receiver has a notch recessed from the back surface of the receiver, and the contact spring body is inserted into the cutout and inserted into the spring body housing. The purpose of the present invention is to provide a fluorescent lamp socket that is compact, easy to assemble, and has a small number of parts, by eliminating the above-mentioned conventional drawbacks by housing the contact spring body and bringing the free end of the contact spring body into contact with the pin insertion hole. There is.

An embodiment of this invention will be described below with reference to FIGS. 3 to 6.

Reference numeral 1 designates a bag-shaped socket main body having an insertion hole 5 formed on the front surface and an open bottom. Reference numeral 3 denotes a receiver inserted into the insertion hole 5 of the socket main body 1, which is approximately box-shaped with an open back surface, and whose lower part 7 is approximately rectangular.
A pair of pin insertion holes 8 are provided on the front surface, and a spring body storage recess 9 whose lower part is approximately rectangular is provided on the back side in communication with the pin insertion holes 8, and further, the lower side wall 10 is recessed from the back surface. A notch 11 is provided. 6 is a pair of contact spring bodies, each of which is
It is constructed by overlapping a strip-shaped conductive plate 2 and a strip-shaped leaf spring 12. Reference numeral 13 denotes a substantially E-shaped holder, which has a locking groove portion 14 . The above contact spring body 6
has its lower end locked in the locking groove 14 of the holder 13, and is inserted together with the holder 13 from the bottom opening of the socket body 1, and the free end of the contact spring body 6 is inserted into the spring body through the notch 11 of the receiver 3. Storage recess 9
The pin insertion hole 8 is housed in the pin insertion hole 8 on the inside of the front surface of the receiver 3.

The above-mentioned fluorescent lamp socket is provided with a receiver 3 that is approximately box-shaped with an open back and a lower portion 7 that is approximately rectangular, and this receiver has a lower portion on the back side that communicates with a pin insertion hole. Since a substantially rectangular spring body storage recess 9 is provided and the strip-shaped contact spring body 6 is stored in this spring body storage recess 9, there is no wasted space in the receiver 3 corresponding to the shape of the contact spring body 6. Therefore, the receiver 3 can be made smaller, and therefore the fluorescent lamp socket can be made smaller. Further, the lower side wall of the receiver 3 has a notch 11 recessed from the back surface of the receiver 3, and the contact spring body 6 is inserted into this notch and stored in the spring body storage recess 9. Therefore, there is no wasted space in the receiver 3, and the receiver 3 can be made more compact. Furthermore, the socket main body 1 is formed into a substantially bag-like shape with an open bottom, and the contact spring body 6 is fixed to the holder 13.
Since the socket body 1 and the holder 13 are inserted through the bottom opening of the socket body 1, the socket body 1 can be formed from one member, and assembly is easy.

Since this invention is constructed as described above, it has the advantage of being able to provide a fluorescent lamp socket that is compact, easy to assemble, and has a small number of parts.
