Abstract

The utility model is a connector, which is fixed on a circuit board and is connected with the lighting tube. The connector comprises a connector body, a terminal block, a sliding closure and a fixed block; wherein, the connector body is provided with a lighting tube holding chamber, a terminal holding chamber and a stop catch part. The sliding closure is arranged on top of the terminal holding chamber which can properly slip in the terminal holding chamber, by which the lighting tube can be replaced by only slipping the sliding closure backwards and simultaneously forcing the terminal block in the terminal holding chamber to unlock the need, thus the lighting tube can be taken out from the connector. When finishing the replacement of the lighting tube, slip the sliding closure back to the default position, thus the heel block on the sliding closure can prop and catch the terminal block again to make the nip tightly closed and simultaneously the holding elastic arms are firmly held on the electrode of the lighting tube, thus the replacing work of the single lighting tube is finished.

Description

Connector

Technical field

The utility model especially is applicable to the connector that links fluorescent tube relevant for a kind of design of connector.

Background technology

In space utilization and hang down amount of radiation and guarantee under user's health that traditional tv and CRT computer display are replaced by LCD of new generation and LCD TV gradually, so-called LCD (Liquid Crystal Display; LCD), in the middle of two parallel glass planars, place liquid crystal, the tiny electric wire that many vertical and levels are then arranged in the middle of this two sheet glass, see through energising and cold action, controlling shaft-like quartzy molecular changes direction produces light refraction and display frame, replace the negative voltage that CRT monitor utilizes display rear end negative electrode coil to be emitted, driving electron gun beats at the arcuation that is coated with full phosphide electron beam on glass, therefore LCD more can significantly reduce the amount of radiation as electron gun except can reaching the frivolous purpose of product.

But, LCD is not so good as traditional monitor after all on service life, main cause is that its backlight module that light source is provided is based on CCFL, under certain use amount, fluorescent tube still has the stain generation and influences the light refraction image effect, more as shown in Figure 1, the mode of connection of backlight module and external power source output 62 is because of considering fluorescent tube 90 elongated and easily crisp characteristics own at present, must be during wiring earlier at substrate 60 both sides wiring place configuration supports 61, after fluorescent tube 90 is arranged in support 61, input 92 and external power source output 62 with welding manner winding fluorescent tube 90 forms pad 70 again, but if 90 fractures of one fluorescent tube or generation stain damage, must earlier its pad 70 be removed and just can carry out maintain and replace, re-assembly fluorescent tube 90 and also must just can carry out wiring with welding manner again, therefore can't single immediately replacing fluorescent tube 90, cause the user to keep in repair a puzzlement greatly, also therefore wiring problem, more cause the fluorescent tube of backlight module in the LCD in case damage (even if having only a tubes), also to face and be dropped the end that to use, not only causing LCD not bring into play it fully should have the benefit in service life, and causes relevant environmental issue.

The utility model content

The purpose of this utility model is to provide a kind of connector, to solve that known fluorescent tube can't independently be changed and problem during replacement cost.

The technical scheme that the utility model adopted is: comprise that connector is fixed on the circuit board, and be connected with fluorescent tube, and connector includes body, terminal base, slip lid and fixture, wherein has the fluorescent tube accommodation chamber on the body, terminal accommodation chamber and stopper section, and slip lid is equipped on the top of terminal accommodation chamber, and can be in the terminal accommodation chamber suitably slippage, by this, when fluorescent tube need be changed, only need slip lid is passed backward, force the terminal base in the terminal accommodation chamber to open the folder mouth simultaneously, fluorescent tube can be taken out in connector, after the fluorescent tube replacing finishes, again slip lid is pushed back to predeterminated position, allow the pushing block on the slip lid push up the terminal base of pulling once more, make tight-lipped the closing of folder make the clamping elastic arm firmly be held on the electrode of fluorescent tube simultaneously, thus, just finished the replacing operation of single tubes.

The beneficial effects of the utility model are: obtain a kind of connector and can change the design of single tubes separately, and obtain the design that a kind of connector has quick replacing fluorescent tube.
