The specific embodiment
To shown in Figure 5, basically, the utility model lamp bracket structure is by circuit board 1 as Fig. 2, holder 2, and light fixture 3 combines.
Wherein, this circuit board 1 has the configuration of interlock circuit and driver, so that chat light fixture 3 after driving, and cold-cathode tube lighting for example.As shown in Figure 2, this circuit board 1 is oppositely arranged at least one pair of metal inserting terminal 11 according to the length of this light fixture 3, and each inserting terminal 11 is made up of two elasticity jig arm 111 of symmetry and many foldings face, and an elasticity jig arm 111 outer ends flanging 112 that extends internally wherein, it is as light fixture 3 axially movable backstops.
And for providing holder 2 to be fixedly arranged on the circuit board 1, be with, a plate hole 12 is radially offered in each inserting terminal 11 inboard.
To shown in Figure 5, the button hook 224 of this snapping sheet 222 can be snapped in the catching groove 223 of operating sheet 221, to form a lock-out state as Fig. 4.In addition, this clamp ring 21 bottom longitudinal extensions one inserting column 23, but its bottom has the hook part 231 of an elastic telescopic, and for example the bottom is circular-arc and the upwardly extending arrow sagittal of two sides trip, the prominent pair of flanges 232 of establishing of this top, arrow sagittal trip both sides inner edge.Into person is arranged especially, the adjacent surface of this inserting column 23 and clamp ring 21 is to having an arc top holding piece 233, it is and hook part 231 common clamping circuit boards 1, and this top holding piece 233 offers a pair of groove 234 relatively in abutting connection with these inserting column 23 dual-sides, to absorb the deflection of these top holding piece 233 longitudinal elasticity liftings.
Group immediately, the hook part 231 of these holder 2 bottoms is intercalated in the plate hole 12 of circuit board 1, make this hook part 231 by compressed in these plate hole 12 processes and stretching, extension, make hook part 231 be snapped in plate hole 12, and the pair of flanges 232 on top is placed in the plate hole 12, and these arc top holding piece 233 two ends then elasticity press this circuit board 1 end face.
And the technical characterictic of this holder 2 is, these clamp ring 21 inner peripheral surfaces are dashed forward and are established a plurality of contact ribs 212, and be to form preferable clamping effect with light fixture 3, be to connect with arc clip 213, each arc clip 213 inner face is contacted with fluorescent tube 31 with these adjacent contact rib 212 inner compartment of terrains.
As desire the assembling lamp shelf structure, and at first the plate hole 12 with the hook part 231 alignment circuit plates 1 of holder 2 bottoms inserts, and it is online to make each holder 2 be positioned the axle of inserting terminal 11 inboards.At this moment, the locking device 22 that clamp ring 21 openings 211 of each holder 2 are radially stretched out is to be unlocked open state, that is this operating sheet 221 and snapping sheet 222 are to be the separation kenel.Therefore, assembler can be aimed at both sides inserting terminal 11 with the conductive part 32 at light fixture 3 two ends like a cork and be inserted, simultaneously in this insertion process, the fluorescent tube 31 of light fixture 3 also passes through the operating sheet 221 and snapping sheet 222 of locking device 22, and form as shown in Figure 3, this fluorescent tube 31 is supported by the contact rib 212 of clamp ring 21 inside and arc clip 213.
At last, assembler only need be pushed the locking device 22 of each holder 2, operating sheet 221 and snapping sheet 222 are drawn close each other, and made button hook 224 be snapped in the catching groove 223, to form lock-out state, and with opening 211 sealing of clamp ring 21, at this moment, clamp ring 21 is inner promptly as Fig. 4 and shown in Figure 5, and each contacts rib 212 the inners and arc clip 213 common double team fluorescent tubes 31, make that fluorescent tube 3 is unlikely radially to break away from holder 2, and effectively by these clamp ring 21 clampings.
Please consult Fig. 5 again, because the arc clip 213 of these adjacent contact rib 212 the inners is to adopt connection is set at interval, and has the space of distortion, so work as whole lamp bracket structure in the process of carrying or transportation, these contact ribs 212 can absorb the vibration that light fixture 3 is taken place effectively with arc clip 213, the conductive part 32 of this light fixture 3 can be stablized between the two elasticity jig arm 111 that are plugged in inserting terminal 11, and the facts that unlikely generation is slided or got loose.
So, via enforcement of the present utility model, the effect that it gained is, this holder is fixedly arranged on the axis of circuit board inserting terminal inboard, and during this holder non-locking, can be inserted in the clamp ring of this holder for the fluorescent tube of light fixture, and by a plurality of contact ribs and the inner arc clip clamping that connects at interval of adopting thereof, except that the vibration that can absorb light fixture effectively and taken place, and the conductive part of light fixture can be able to be stablized between the two elasticity jig arm that are plugged in inserting terminal, and the facts that unlikely generation is slided or got loose can be rated as a ware big good structure not seen before.
That the utility model disclosed is a kind of of preferred embodiment, and patent right category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be what those skilled in the art were easy to know by inference such as.
