Description
[technical field]
The invention relates to a kind of in order to fix the connector of a flexible circuit board, particularly about a kind of connector of display equipment.
[background technology]
Flexible circuit board (flexible printed circuit; FPC) be a kind of signal transmission element, itself have do not take up space, advantage such as deflection, high signal transmittability, so be applied in widely at present in many electronic products, the many and connector collocation use of flexible circuit board at present is so as to signal between transmission system or power supply.
With reference to figure 1, at present common is a kind of flip formula connector in order to the fixing connector 30 of flexible circuit board 26, it compresses flexible circuit board 26 downwards by turnover qin lid 34 (also can be described as flip), to reach the fixedly purpose of flexible circuit board 26, and pin on the flexible circuit board 26 (figure does not show) is finished with the pin (figure does not show) on the printed circuit board (PCB) electrically conduct, and can be convenient to assembling/taking-up flexible circuit board 26.Yet the qin lid 34 of this type of connector 26 all lacks fixed mechanism, that is after qin lid 34 is swung down to extreme lower position, there is no suitable mechanism and fix qin lid 34.Suppose that the improper effect of external force or flexible circuit board 26 are stressed to be pulled outwardly when pulling when qin lid 34 is subjected to, regular meeting causes qin lid 34 to open, flexible circuit board 26 thereby break away from, and then cause the inefficacy that electrically conducts between flexible circuit board and printed circuit board (PCB).
The lamp bar of the module backlight of LCD device (light bar) is a connector 30 of fixing and be electrically connected to printed circuit board (PCB) 16 by flexible circuit board, lights liquid crystal panel to drive the lamp bar.Yet existing connector 30 does not have and prevents flexible circuit board 26 mechanism that comes off, and causes in liquid crystal panel assembling and the test process to cause flexible circuit board 26 to come off, and can't light a lamp smoothly.According to existing improvement situation, then be a slice flexible circuit board adhesive tapes (FPC tape) (shown in dotted line 28) that paste above the junction of flexible circuit board 26 and connector 30, in case anti-avulsion falls more.But, if must dismounting the time, the flexible circuit board adhesive tape of then must tearing earlier, remove flexible circuit board 26 again, turn back to flexible circuit board 26 then, the flexible circuit board adhesive tape is aimed at pasted back at last, so repeated steps increases the heavy industry time, and is for assembler, inconvenient really.
Therefore, just having to provide a kind of in order to the fixing connector of flexible circuit board, can solve aforesaid problem.
