Abstract

The invention discloses a fixing device of a backlight module lamp strip, which aims at improving the problems caused by welding. The fixing device comprises a fixing base and a guide plate, wherein, one end of the fixing base is fixed on a circuit board, the other end is provided with a supporting slot to accommodate the lamp strip, and both sides of the supporting slot are respectively provided with a perforation, both perforations pass through the bottom part of the fixing base. The guide plate is provided with a wire slot and two contact ends, wherein, the wire slot is positioned on the supporting slot to accommodate the wires of the lamp strip, and the two contact ends pass through the two perforations and are connected with the circuit board. A packing guide slot is arranged between the wire slot and the support slot to provide a packing device which can be inserted from the outside of the fixing base, so the fixing function of the fixing device is more firmly.

Description

technical field [0001] The invention relates to a fixing device for a lamp tube of a backlight module. Background technique [0002] With the advancement of science and technology, various information products such as mobile phones, notebook computers, digital cameras, PDAs, LCD screens and other products are becoming more and more popular, which greatly increases the demand for LCD displays. Only the setting of a backlight source can be displayed, and the backlight module is mainly used as a backlight source of the liquid crystal display. [0003] The backlight module includes a circuit board, at least one light source, a reflector, a diffuser plate, etc. The light source used today includes a cold cathode fluorescent lamp (Cold Cathode Fluorescent Lamp; CCFL), an external electrode fluorescent lamp (External Electrode Fluorescent Lamp) ; EEFL) or Light Emitted Diode (Light Emitted Diode; LED), wherein the circuit board of the backlight module using CCFL as the backlight i...
