The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
Embodiment
The ultra thin LED lamp bar weld jig of the present embodiment such as Fig. 1 are to shown in Figure 7, comprise that the spacing supporting plate 1 of rectangle (also can select other polygon as required, such as triangle, pentagon, irregular quadrilateral etc.), spacing supporting plate 1 outward flange extends positive stop lug boss 1-1 to supporting plate 1 the same side, and positive stop lug boss 1-1 surrounds groove 1-2; LED lamp bar comprises printed board 4-1, is electrically connected with the light-emitting area luminous tube 4-2 vertical with printed board on the printed board 4-1.
Be mounted with in the groove 1-2 of supporting plate 1 in order to clamp the LED lamp bar printed board 4-1 vertical with spacing supporting plate 1 and the clamping device of LED lamp bar luminous tube 4-2; After the anchor clamps assembling, the clamping device bottom outer edge contacts with groove 1-2 inwall.This has just formed simple and effective position limiting structure, and need not the adjustment precision during use can accurately locate.
Particularly, clamping device is by two halves fastener 2-1,2-2 involutes, half fastener 2-1,2-2 comprises respectively the substrate 3-1 parallel with spacing supporting plate 1,3-2, substrate 3-1,3-2 extends towards printed board 4-1 respectively near the outward flange of LED lamp bar printed board 4-1 and equidistantly arranges and the convex tendon 5-1 parallel with spacing supporting plate 1,5-2, convex tendon 5-1,5-2 is respectively towards extend the boss 6-1 vertical with spacing supporting plate 1 away from the direction of spacing supporting plate 1,6-2, boss 6-1,6-2 is mounted with the top board 7-1 that connects adjacent lands away from the side of supporting plate 1,7-2, top board 7-1,7-2 has respectively the some depressions 8 that match with corresponding LED lamp bar luminous tube 4-2 towards the side of printed board 4-1; Surround respectively weld pass 11 between adjacent convex tendon on the substrate, boss and the corresponding top board.
After the anchor clamps assembling, substrate 3-1,3-2 contact with groove 1-2 inwall near the outward flange of supporting plate groove 1-2 inwall; The convex tendon 5-1 of half fastener 2-1, boss 6-1, top board 7-1 are mutually involutory with convex tendon 5-2, boss 6-2, the top board 7-2 of half fastener 2-2 respectively, jointly form the space of clamping LED lamp bar printed board 4-1 and LED lamp bar luminous tube 4-2.After adopting such structure, as long as the mutual involutory side of the above-mentioned parts of two halves fastener keeps smooth and can realize effective clamping perpendicular to supporting plate, guarantee the validity of anchor clamps.
Also be mounted with one group on the supporting plate 1 in order to compress the metal card article 9 of half fastener 2-1,2-2, card article 9 is several fonts; After the assembling, card article 9 one ends are fixedly connected with the positive stop lug boss 1-1 of supporting plate 1 through securing member, and card article 9 other ends contact with top board 7-1, the 7-2 of half fastener 2-1,2-2, and elastic like this card article is about to half fastener and is pressed in the supporting plate groove; Card article 9 is circumferentially with rubber washer 10, half fastener of avoiding wearing and tearing with the contacted position of top board 7-1,7-2.
