Abstract

The utility model discloses a lamp holder for a tube, belonging to the field of lamp sockets for illuminating lamps. The lamp holder comprises a holder body, a pin plugboard which can be connected with a conductive pin of the tube, a conductive spring plate which can be connected with an external power supply, and a rotating buckle structure which can rotate with a certain angle in the holder body; wherein the rotating buckle structure mainly consists of an upper disk, a connecting sheet and an extruding block, two ends of the connecting sheet are respectively fixedly connected with the upper disk and the extruding block; and both the conductive spring plate and the rotating buckle structure are movably arranged in the holder body. When the rotating buckle structure rotates in the holder body, the extruding block can rotate therewith to push the conductive spring plate to perform elastic deformation, thus the pin of the tube can be tightly contacted with the conductive spring plate. The lamp holder of the utility model can effectively avoid the phenomenon that the pin of the tube is poorly contacted with the conductive spring plate, and can raise safety, in addition, all components of the lamp holder are designed detachably, thus the lamp holder can be maintained conveniently.

Description

The fluorescent tube lamp socket

Technical field

The utility model relates to lighting lamp socket field, the lamp socket that particularly a kind of illuminating lamp tube is used.

Background technology

Fluorescent tube is present widely used lighting; And form by base, pin plate, electroconductive elastic sheet, lid with the supporting lamp socket majority of fluorescent tube on the market; The fluorescent tube pin contacts and energized with electroconductive elastic sheet; Mainly rely on the elastic deformation stress of electroconductive elastic sheet and keep the fluorescent tube pin to contact, be easy to generate poor contact phenomenon after long-term the use with the tight of electroconductive elastic sheet.Also have in the prior art to fluorescent tube pin and electroconductive elastic sheet loose contact and improved design is " lamp socket and electronic equipment " utility model patent of ZL201020269114.3 like the patent No., comprise the relative location wall of pedestal, position, lid, by the power supply terminal of elastic conductor material system; Said lid articulates or is hinged on the wall of location, is installed with the relative clamping wall in position on the lid, in the time of in lid is reset to pedestal; The position relative to clamping wall move and prop up power supply terminal; Though this prior art can make the fluorescent tube pin closely contact with power supply terminal, complex structure, processing cost is high; Lid is difficult to pull down, the inconvenience maintenance.

Therefore, the fluorescent tube pin is closely contacted reliably with electroconductive elastic sheet, folding simple in structure again, easy is adorned, is convenient to keep in repair is the technical problem that needs to be resolved hurrily in the industry.

Summary of the invention

The main purpose of the utility model provides a kind of fluorescent tube lamp socket that fluorescent tube pin and electroconductive elastic sheet can closely be contacted reliably, and each critical piece of this holder structure is movable to be installed, and simple in structure, easy dismounting, is convenient to maintenance.

The utility model proposes a kind of fluorescent tube lamp socket; Comprise pedestal, the pin plate that can be connected and the electroconductive elastic sheet that can be connected with external power source with the fluorescent tube conductive pin; Also comprise the turn buckle structure that can in said pedestal, turn an angle; Said turn buckle structure mainly is made up of last disk, brace and crushing block, and said brace two ends are fixedly connected with said upward disk, crushing block respectively, and said electroconductive elastic sheet, turn buckle structure all are movably arranged in the said pedestal.

Preferably, said crushing block is that ellipse, cydariform or two are fan-shaped relatively.

Said going up on the disk has rectangular groove, and said going up setting firmly rotating handle or rotation convexity on the disk.

Said pedestal has uncovered up, and open-mouth is provided with the annular recess that adapts with said upward disk shape, and said pedestal one side is provided with slot, and the shape of slot shape and said electroconductive elastic sheet, pin plate adapts.

Said electroconductive elastic sheet is two of split.

The utility model beneficial effect is: when said turn buckle structure is rotated; Crushing block extruding electroconductive elastic sheet makes the fluorescent tube pin closely contact with electroconductive elastic sheet; The long-term use can not come in contact bad phenomenon yet; Also improved fail safe, be not threaded to on-position, also can not switch on even fluorescent tube has been installed like the turn buckle structure; Mobile assembled and disassembled pedestal, pin plate, electroconductive elastic sheet, turn buckle structure are convenient to maintenance, and be easy to process; Two split-type design of said electroconductive elastic sheet, easy disassembly; The rectangular groove that said upward disk is being opened can be convenient to turn buckle structure location and observe lamp socket inner.
