Embodiment
To make the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings to the utility model
Embodiment is described in further detail.
As shown in figure 1, which show a kind of backlight provided by the utility model PCB and the elastic conjunction tool of PIN needle
Structural representation.The backlight PCB and the elastic conjunction tool of PIN needle include being used for placing and position PCB2 and PIN needle 3
Jig plate 1 and the pressing plate 4 being correspondingly arranged with the jig plate 1；The PCB2 is single plate structure or layout structure, in the present embodiment
In, as Figure 2-3, the PCB2 is the jigsaw structure that multiple veneers 21 with independent complete line are spliced to form；It is described
PCB2 is provided with the PIN holes 211 of PIN interference fits and the pad 212 for welding PIN needle 3；The PIN needle 3 includes wearing
PIN bodies 31, the PIN first 32 being interference fitted with PIN holes 211 and the size for crossing PIN holes 211 are more than the PIN caps 33 in PIN holes 211.
Specifically, as illustrated in figures 4-5, the upper surface 11 of the jig plate 1 is used to place PCB2, is gone back on the jig plate 1
Provided with multiple positioning through hole 12；The PIN holes 211 of the positioning through hole 12 and PIN needle 3 and PCB2 are correspondingly arranged, for position and
Accommodate the PIN needle 3；The positioning through hole 12 is shaped as the annular through hole with horn mouth 121.Horn mouth 121 is set
Annular through hole contributes to the placement and positioning of PIN needle 3, in the present embodiment, when PIN bodies 31 pass through PCB2 when placing PIN needle 3
PIN holes 211 after when entering positioning through hole 12, enter positioning through hole 12 because horn mouth 121 is larger therefore is advantageous to PIN needle 3,
Then zooming in the shape of horn mouth 121, the position of adjustment PIN bodies 31 can be guided automatically, it is fixed so as to conveniently realize
Position through hole 12 accommodates the effect of positioning PIN needle 3.In the present embodiment, the pressing plate 4 is used for the interference fit of the PIN needle 3
Portion is pressed into the PCB2, and in the present embodiment, the interference fit portion of the PIN needle 3 is PIN first 32.
Further, as shown in fig. 6, being additionally provided with guide 13 on the jig plate 1, the PCB2 is provided with and guide
First guide part 22 corresponding to 13, the pressing plate 4 is provided with second guide part 41 corresponding with guide 13, in the present embodiment
In, the guide 13 is four through holes located at the marginal position of jig plate 1, and first guide part 22 is that four diameters are more than

Individual diameter is more than or equal to four through holes of guide 13；Second guide part 41 is four through holes on pressing plate 4.This
Sample, by there is provided the cooperation of the post holes of the guide part 22 of guide 13 and first and the second guide part 41, on the one hand being put by PCB2
Being placed in has the foundation of positioning when on jig plate 1, can be quickly according to the first guide part 22 and the position relationship of guide 13
The quick position for determining PCB2, meanwhile, determine that the position of pressing plate 4 can also be according to the position of the second guide part 41 and guide 13
Realize that pressing plate 4 is sheathed in jig plate 1 by fast positioning, improve efficiency of assembling；On the other hand, using pressing plate 4 by the PIN
When the interference fit portion of pin 3 is pressed into the PCB2, due to the second guide 13 and guide 13 be four columns and
The cooperation of through hole, actually having determined that the motion road strength of pressing plate 4 can only move along the axial direction of column or through hole, so
Planarization of the pressing plate 4 when PIN is pressed into PCB2 can be ensured, it is crooked to ensure that PIN needle 3 does not occur, effectively avoids PCB2 from filling
It is destroyed during matching somebody with somebody, improves product quality.
Further, as shown in figure 8, the backlight also includes being used for crest with PCB2 and the elastic conjunction tool of PIN needle 3
The steel mesh of weldering, the steel mesh are provided with scolding tin hole corresponding with the pad 212 on PCB2.Can be with using the steel mesh with scolding tin hole
Help accurately to be covered in solder(ing) paste on pad 212 in brush solder(ing) paste, so as to reduce welding job man-hour, improve
Production efficiency.Further, the 3rd guide part 52 corresponding to guide 13 can also be arranged on the steel mesh, so as to place
Efficiency of assembling is effectively improved to align can using the position relationship between the guide part 52 of guide 13 and the 3rd during steel mesh,
The accurate contraposition contributed between pad 212 and scolding tin hole 51.
To sum up, backlight provided by the utility model can be by provided with guide with the elastic conjunction tool of PCB and PIN needle
13 and jig plate 1, the pressing plate 4 provided with the second guide part 41 and the steel mesh located at the 3rd guide part 52 of positioning through hole 12, with
The first guide part 22 for being used to coordinate with guide 13 that PCB2 is provided with, realize to the backlight of interference fit with PCB2 and
PIN needle 3 carries out the function of batch assembling, and assembling process simple and fast, efficiency of assembling is effectively increased, simultaneously because pressing plate 4
It can only be moved along the axial direction that guide 13 determines with the second guide part 41, ensure that PIN needle 3 is pressed when being plugged in PCB2
Enter the stabilization in direction, effectively increase product quality.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute
