Abstract

The present invention provides a socket, which includes an insulation housing, conductive silicone rubber received in the insulation housing, and a conductive plate mounted to the insulation housing. The conductive plate has an end electrically connected to the conductive silicone rubber and an opposite end extending outside the insulation housing for external electrical connection. The present invention provides a socket that comprises an insulation housing in which a block of flexible conductive silicone rubber is received and retained to allow a lead pin of a light tube to be easily inserted into the conductive silicone rubber for realizing mounting the light tube to socket to be in electrical connection with the socket. Further, the conductive silicone rubber used in the present invention shows a cushioning capability that provides protection to the light tube.

Claims

1. A socket, comprising:

an insulation housing, a conductive silicone rubber received in the insulation housing, and a conductive plate mounted to the insulation housing, the conductive plate having an end electrically connected to the conductive silicone rubber and an opposite end extending outside the insulation housing for external electrical connection, wherein the conductive silicone rubber has an exposed outside surface forming a recess for receiving and directly engaging an end of a tuber body of a light tube to resiliently support the light tube and the conductive silicone rubber forms an insertion bore extending inward from a bottom of the recess for receiving insertion of a lead pin extending from the tube body of the light tube to electrically engage the lead pin, whereby the conductive silicone rubber simultaneously electrically engage the light tube and resiliently support the light tube.

2. The socket as claimed in claim 1, wherein the insulation housing has an end forming an opening and the opening defines an inward recessed receiving space, the conductive silicone rubber being received in the receiving space in such a way that the exposed outside surface of the conductive silicone rubber is substantially flush with the end of the insulation housing.

3. The socket as claimed in claim 2, wherein the insulation housing has a sidewall for the receiving space, which defines a mounting surface mountable to a circuit board, the sidewall forming a mounting hole, the conductive plate being received in the mounting hole with an end electrically connected to the conductive silicone rubber and an opposite end extending outside the insulation housing for electrical connection with the circuit board.

4. The socket as claimed in claim 3, wherein the recess is located at a center of the outside surface of the conductive silicone rubber and the mounting surface is a planar surface.

5. The socket as claimed in claim 1, wherein the insulation housing is made of a plastic insulation material.

6. The socket as claimed in claim 1, wherein the conductive silicone rubber is flexible and the conductive plate is a metal plate.

7. The socket as claimed in claim 1, wherein the socket is used with a backlight module of a liquid crystal display.
