Description of the Related Art Conventionally, as a socket of this type, a receiving plate which receives an end of a lamp and has a pin hole through which a lamp pin penetrates is applied from the back side of an opening provided in the front of the socket, and one end is fixed to the socket. It is known that the vicinity of the pin hole of the receiving plate is pressed by the abutting portion at the other end of the leaf spring-shaped conductive piece (for example, Japanese Utility Model 1─4383).
No. 1). In this type of socket, the lamp is sandwiched between a pair of opposed sockets in a state where a lamp pin is inserted into a pin hole and an end of the lamp is pressed against a receiving plate of the socket. At this time, the end of the lamp pin penetrating the pin hole comes into contact with the contact portion of the conductive piece pressing the receiving plate against the inner wall of the socket,
The conduction between the lamp pin and the conductive piece is achieved.

になるおそれがあった。However, in the above prior art, since the end of the lamp pin contacts the conductive piece, if the end of the lamp pin has irregularities due to variations in the manufacturing process, the contact area becomes small. There was a possibility that the conductivity became unstable.

くてはならない問題もあった。Before the lamp is mounted, the conductive piece presses the receiving plate, but after the lamp is mounted, the lamp pins penetrating through the pin holes of the receiving plate come into contact with the receiving plate. There is a possibility that the receiving plate to be pressed may not fulfill its function, and there is also a problem that a coil spring for pressing the receiving plate must be separately provided.

However, in this known invention, the object through which the lamp pin is inserted is an H-shaped slit that has been punched out, so the restoring force when deformed is weak. There is a possibility that the inner edge of the slit slightly deformed by the pushing and opening does not contact the outer periphery of the lamp pin well even if the slit is inserted. In addition, there is another problem that a complicated H-shaped slit must be punched in the conductive piece, which requires a high manufacturing cost.

At the same time, the other end is pulled up to make the contact portion 2 with the receiving plate 20 (see FIG. 4). Then, the contact portion 2 side of the conductive piece 1 is cut in a forked shape, and the forked notch 3 is set to have a width in which the lamp pin LP can be inserted. The notch 3 needs to be easily pushed and opened by the insertion lamp pin LP, and it is necessary to secure sufficient elasticity in the pushing and opening direction so as to return to the original shape when the notch 3 is pulled out. Is notch 3
It is realized by increasing the overall length of the motor and securing the stroke. In this case, how much total length is required
As an example, in this embodiment, the length is set to be equal to or longer than the entire length of the contact portion 2 of the conductive piece (see FIGS. 1 and 3).

かかわらず常に良好な導通が実現される。The fluorescent lamp socket of the present invention having the above configuration has the following specific effects. The contact between the inner edge of the notch and the outer periphery of the lamp pin is realized by inserting the lamp pin into the forked cutout provided in the conductive piece instead of contacting the end of the lamp pin with the conductive piece.
Good conduction is always achieved irrespective of the irregularities at the ends of the lamp pins due to variations in the manufacturing process.

なる。As a result of the lamp pin penetrating through the bifurcated cutout provided in the conductive piece, the contact portion of the conductive piece presses the receiving plate even when the lamp is mounted, so that the lamp can be securely clamped. An auxiliary coil spring for pressing the plate is not required, and the structure of the socket can be simplified.

ある場合でも確実な導通作用が実現される。Since the lamp pin is inserted into a bifurcated notch provided in the conductive piece whose one end is opened, the stroke of the notch pushed and opened by the lamp pin is secured by increasing the total length of the notch. Therefore, sufficient elasticity of the notch can be secured. Therefore, after the lamp pin is pulled out, the notch of the conductive piece surely returns to the initial shape, so that a reliable conduction action is realized even when the thickness of the lamp pin varies.
