Summary of the invention
The technical problems to be solved in the utility model is, flexibly connects at the above-mentioned employing of prior art to be easy to generate overheated and problem of aging, and the big complete machine defective attractive in appearance inadequately that takes up room provides a kind of LED-backlit plate.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of LED-backlit plate, the polylith LED lamp plate and the driving power that comprise electrical connection, each described LED lamp plate is electrically connected with drive circuit board, and described drive circuit board and described LED lamp plate are realized being rigidly connected by connector.
In a kind of LED-backlit plate described in the utility model, described connector is female type terminal and rigidity contact pin, and described LED lamp plate has welding hole, and the pin of described female type terminal is welded in the described welding hole; Vertical welding is connected to described rigidity contact pin on the described drive circuit board, and the spliced eye of described rigidity contact pin and described female type terminal is pegged graft.
In a kind of LED-backlit plate described in the utility model, described female type terminal is double 16 spring hole scoket formula terminals, correspondingly on the described drive circuit board is welded with 16 rigidity contact pins; With label in the described double 16 spring hole scoket formula terminals is the positive pole that the corresponding described rigidity contact pin of 1,2,3,4 spliced eye interconnects and 13,14,15,16 spliced eye is corresponding described rigidity contact pin was connected to each other and was connected to simultaneously described LED lamp onboard led lamp, and the rigidity contact pin of the spliced eye correspondence of all the other labels is connected to the negative pole of described LED lamp onboard led lamp.
In a kind of LED-backlit plate described in the utility model, described connector is the rigidity contact pin, and described rigidity contact pin is vertically welded on the described drive circuit board; Supporting with it socket then is welded in the corresponding jack of lamp plate.
In a kind of LED-backlit plate described in the utility model, the two ends of described drive circuit board also have the through hole that is used to install and fix double-screw bolt.
Implement a kind of LED-backlit plate of the present utility model, have following beneficial effect: have only one to patch face, thereby the reliability height, be not easy to produce phenomenon overheated or that burn out, also can not see any connecting line simultaneously, overall appearance, it is all very convenient to plug; Simultaneously, the connected mode of rigidity contact pin makes in that circuit also can operate as normal when anti-inserted with drive circuit board because of carelessness, has reduced product disqualification rate in process of production.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of a kind of LED-backlit plate first embodiment of the utility model;
Fig. 2 is the structural representation of a kind of LED-backlit plate second embodiment of the utility model;
The figure number explanation: the 1st, LED lamp plate, the 2nd, drive circuit board, the 3rd, female type terminal, the 4th, rigidity contact pin, the 5th, welding hole, the 6th, through hole.
The specific embodiment
First embodiment:
As shown in Figure 1, in first embodiment of a kind of LED-backlit plate of the present utility model, the LED-backlit plate is electrically connected by polylith LED lamp plate 1 and forms, and is connected with driving power (not shown) and drive circuit board 2 usually at the rear portion of LED-backlit plate.Shown in the figure is the syndeton schematic diagram of LED lamp plate 1 and drive circuit board 2 wherein.As can be seen from Figure, have two row's welding holes 5 on the LED lamp plate 1, the pin of female type terminal 3 is welded in the welding hole 5, and in the present embodiment, female type terminal 3 is double 16 spring hole scoket formula terminals; Corresponding with it, on drive circuit board 2, welded two rows totally 16 rigidity contact pins 4, rigidity contact pin 4 is inserted in the female type terminal 3 corresponding spliced eyes and forms the loop with LED lamp plate 1.Because have only one to patch face, thus the reliability height, be not easy to produce phenomenon overheated or that burn out, also can not see any connecting line simultaneously, overall appearance, it is all very convenient to plug.Simultaneously, cause circuit to burn out or inoperable situation, 16 rigidity contact pins 4 have been done some processing for fear of anti-inserted.The spliced eye label from 1 to 16 of 16 spring hole scoket formula terminals, with label is rigidity contact pin 4 connections of 1,2,3,4 spliced eye correspondences, with label is rigidity contact pin 4 connections of 13,14,15,16 spliced eye correspondences, and then these two parts that will connect insert the positive pole of LED lamp on the LED lamp plate 1, the negative pole of LED lamp on the rigidity contact pin 4 access LED lamp plates 1 of all the other label correspondences.Like this, even because of carelessness that drive plate circuit board 2 is anti-inserted in when assembling, circuit still can operate as normal, reduces the disqualification rate of product in assembling process greatly.
Simultaneously,, also respectively have a through hole 6, be used to install and fix double-screw bolt in the both sides of drive circuit board 2 for drive circuit board 2 can fixedly secure on LED lamp plate 1.Concrete grammar is: behind the drive circuit board 2 of having pegged graft, two double-screw bolts of drive circuit board 2 usefulness are fixed on the installing plate (not shown), installing plate and LED lamp plate 1 are fixing, are used for the required Switching Power Supply of erection unit, parts such as image card.
Second embodiment:
In second embodiment of the of the present utility model a kind of LED-backlit plate shown in Fig. 2, each building block of LED-backlit plate is identical with first embodiment, on drive circuit board 2, still be welded with rigidity contact pin 4, on LED lamp plate 1, have corresponding welding hole 5, then rigidity contact pin 4 is connected according to the connected mode among first embodiment, peg graft then and be welded in the welding hole 5.Similarly, respectively have a through hole 6, be used to install and fix double-screw bolt in the both sides of drive circuit board 2.
Above embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement in view of the above, can not limit protection domain of the present utility model.All equalizations of being done with the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
