Connector

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of available buffer and disperses stress that fluorescent tube applied and the connector that reduces the jig arm deflection.

Background technology

Display panels has been widely used among various information, communication, the consumer products.So, since in the display panels liquid crystal itself do not have a characteristics of luminescence.Therefore, for reaching display effect, needing provides planar light source device to display panels.In the prior art, the display panels with backlight module is well-known thing, and the area source that provides briliancy to fill part and be evenly distributed to panel of LCD is provided its function.

The design of general backlight module is provided with many fluorescent tubes at interval in a side of backboard, and the two ends of fluorescent tube are individually fixed on the connector, and connector then is arranged on the backboard.Because lamp tube structure is comparatively fragile, when a little its glass tube being exerted pressure, is easy to cause damage.When carrying out assembling work, must avoid applying excessive pressure for glass tube.In addition, when the LCD that uses fluorescent tube is safeguarded, also must carefully contact and avoid damaged.

Therefore generally must fluorescent tube could be fixed on the backlight module by the auxiliary of connector, existing lighting tube connector is made up of insulating body with opening and a pair of flexual electroconductive elastic sheet that is arranged in the opening, and at the sheathed metallic sheath of lamp tube ends elder generation, again the metallic sheath extruding is inserted the slit between the electroconductive elastic sheet, elastic-restoring force by electroconductive elastic sheet is seized metallic sheath on both sides by the arms, with this fluorescent tube is fixed on the connector.

Yet, the structural disadvantages of this kind connector is that flexual electroconductive elastic sheet is subjected to the stress influence that fluorescent tube and metallic sheath thereof apply and is easy to generate bigger deflection, this bigger deflection tends to cause electroconductive elastic sheet to be easy to generate the destruction of permanent deformation when assembling, or the elastic-restoring force that electroconductive elastic sheet itself is produced after having assembled can and then weaken, cause fluorescent tube from electroconductive elastic sheet, to break away from the problem that drops easily, so make the production yield when light tube group is loaded on backlight module reduce, and then cause the time of producing and the increase of cost.

The utility model content

The metallic sheath of existing connector and fluorescent tube are when being assembled between the pair of conductive shell fragment, this electroconductive elastic sheet is subjected to stress influence easily and produces bigger deflection, and this bigger deflection often causes the deformation failure of electroconductive elastic sheet easily or causes fluorescent tube to break away from the problem that drops easily from this electroconductive elastic sheet.

The utility model provides a kind of connector, comprises insulating body and conducting terminal, and wherein insulating body has the slot of storage tank and connection storage tank.Conducting terminal is installed in the storage tank of insulating body, wherein conducting terminal has body, two jig arm that are oppositely arranged, fixed part and pin, two jig arm are connected in body, fixed part is connected in body and is positioned at a side of two jig arm, pin is connected in body and is positioned at the below of two jig arm, slot power road plate is pegged graft, two jig arm are in order to seize fluorescent tube on both sides by the arms, and each jig arm is provided with buffer part, this buffer part is in order to increase the length scale of each jig arm, when fluorescent tube was placed between two jig arm, buffer part was disperseed stress intensity that fluorescent tube applied and the deflection that reduces each jig arm.

Connector provided by the utility model, utilize the design of the buffer part on two jig arm of conducting terminal, increase the length scale of each jig arm, when fluorescent tube is placed between two jig arm, this buffer part can disperse fluorescent tube to stress intensity that jig arm caused, and reduce the size of the deflection of each jig arm, make so the electroconductive elastic sheet of connector be not easy to produce the destruction of permanent deformation or cause fluorescent tube from described electroconductive elastic sheet, to break away from the situation that drops easily that the production yield when solving light tube group and be loaded on backlight module with this reduces and the problem of time of producing and cost increase.
