Abstract

The present invention relates to a socket for a cathode tube. The aim of the invention is to provide a socket for a cathode tube, capable of easily absorbing a shrinking difference generated between the cathode tube and a circuit board, a frame and the like due to a temperature difference caused by turning on and off the cathode tube, and absorbing processing error and mounting error of the socket. The socket of the invention is characterized in that a clamping part for holding the side part of a cathode tube terminal part is connected with a mounting part electrically connected by a circuit board by two ends of a first elastic distortion part and a seond elastic distortion part arranged in a basal rightanglle direction relative to the first elastic distortion part.

Description

technical field [0001] The invention relates to a socket for a cathode tube, and is particularly suitable for a socket for a cold cathode tube such as a backlight of a liquid crystal display device. Background technique [0002] As a socket structure for mounting a cold cathode tube (Cold Cathode Fluorescent Lamp: CCFL tube) used in the backlight of a liquid crystal display device such as a liquid crystal television on a rigid circuit board, there are known socket structures such as Figure 7 (a) Structure shown. [0003] The socket 110 has clamping portions 120 clamping the terminal portions 2 provided at both ends of the cold cathode tube 1 . [0004] In addition, the socket 110 is mounted on the circuit board 3, and the circuit board 3 is mounted on the metal frame 5 or the like. [0005] Therefore, when there is a difference in expansion and contraction between the cold cathode tube 1 and the metal frame 5 and the circuit board 3 due to the heat generated when the tub...
