Description
Technical field
The utility model is about a kind of backlight module and connector thereof, and the lamp tube wire that is meant a kind of fluorescent tube especially directly sees through a connector and the backlight module and the connector thereof that electrically connect with current transformer.
Background technology
See also Fig. 1, be the schematic diagram of fluorescent tube in the traditional backlight module and the connected mode between the current transformer.Mainly comprise in the backlight module 100: fluorescent tube 110, lamp tube wire 120, wire rod 130, connector 140 and current transformer 150.Wherein, the lamp tube wire 120 that is disposed at fluorescent tube 110 1 ends is to utilize the mode of welding and wire rod 130 to constitute electric connection, therefore, can have scolding tin 160 between lamp tube wire 120 and wire rod 130.This wire rod 130 is being inserted in corresponding Connection Block 152 on the current transformer 150 through its terminal connector 140, constitutes electric connection so that fluorescent tube 110 sees through wire rod 130 with current transformer 150.
Yet in aforesaid backlight module, the connected mode between its fluorescent tube and the current transformer still produces problem to be solved, and is as follows:
(1) heat dissipation problem: above-mentioned lamp tube wire and wire rod are made of the copper with favorable conductive and thermal conduction characteristic, but owing to the scolding tin that is connected between the two, its conduction and thermal conduction characteristic are relatively poor, therefore, the heat energy that is produced when making the fluorescent tube running easily all concentrates on before the solder joint and can't effectively get rid of, and then influences the useful life of fluorescent tube.
