Description
Technical field
The utility model relates to a kind of connector, is specifically related to a kind of support column for fixed L ED liquid crystal module group backlight source.
Background technology
Along with sharply rising violently of LED TV demand, LED LCD backlight module technology has obtained fast development.In LED LCD backlight module, the connector that meets different demands also has the effect of outbalance.
The LED LCD backlight module of prior art generally includes LGP, reflector plate, sheet metal component and some LED lamps.During assembling, need connector with the reflector plate in LED LCD backlight module stacked with sheet metal component and be fastened to together with, simultaneously connector also will support the another one LGP.Two kinds of modes that are used for herein and realize above-mentioned fastening, support function are arranged in industry.
A kind of is, by screw, object spare is carried out the fastening support of another one support column realization to light guide sheet that be aided with again.The main following points of the drawback of this mode: 1, be papery due to reflector plate or by resin material, made, when locking, metallic screw is than the easy damaged reflector plate; 2,, because screw has imperfect thread section, with screw, be difficult to the object spare of fastening thickness lower than 1.0mm; 3, use screw to take time and effort, affect production efficiency; 4, need two part to realize required function, cause cost higher.
Another kind is to be undertaken fasteningly by the nylon rivet as shown in Fig. 1-7, and is aided with other support column and realizes support function.This nylon rivet comprises rivet 100 and rivet sleeve 200, rivet 100 consists of press head 101 and the pin 102 that is arranged at lower end, rivet sleeve 200 consists of along 202 sleeve 201 and the card that is positioned at sleeve 201 upper ends, the lower end of sleeve 201 becomes the reducing shape, the bottom of sleeve 201 is provided with " ten " word profile groove 203, is expansion clamp clip 204 between adjacent two " ten " word profile grooves 203.During the shipment state, pin 102 is together with sleeve 201 plants cause.During use, in the installing hole of rivet 100 and rivet sleeve 200 insertion objects spares, press the press head 101 of pressure rivet 100, pin 102 is stretched in the sleeve 201 of rivet sleeve 200, the bottom of pin 102 struts the expansion clamp clip 204 of sleeve 201, by card, along 202, with expansion clamp clip 204, object spare is clamped.
Yet after assembling was completed, exposed pin 102 bottoms of nylon rivet, in the assembling process of transportation, carrying or subsequent processing, if pin 102 bottoms are subject to the external force extruding or thereby collision can cause its retraction to lose fastening function; Nylon rivet is without the prompting that is in place, and operating personnel can not judge clearly that product assembles and put in place, have the bad risk of assembling; Nylon rivet, without the rotational positioning function, can arbitrarily rotate, and reduces product reliability; Nylon rivet is comprised of rivet 100 and rivet sleeve 200, and these two parts need to be processed by two molds difference injection mo(u)ldings, then assemble, and produce finished product, complex manufacturing, and cost is high.
