Abstract
The invention relates to an improved loading fixture for miniaturized SMD (Surface Mounted Device) products, which comprises a bottom plate and a top plate, wherein a horizontal locating device and avertical locating device are arranged between the bottom plate and the top plate. The bottom plate is provided with a product groove, the top plate is provided with a through hole which corresponds tothe product groove, and a copper pole is assembled in the through hole. When the improved loading fixture is used, a shell and a cover of a miniaturized SMD product are put into the product groove ofthe bottom plate, and the copper pole is pressed on the corresponding product. The cover and the shell have high wedging degree under the gravity of the copper pole, and the offset of the cover is reduced.

(5) embodiment
As Fig. 1, Fig. 2, Fig. 3 and Fig. 6, Fig. 7, shown in Figure 8, the present invention is a kind of improvement loading fixture of miniaturized SMD products, and it comprises base plate 5 and top board 1, and base plate 5 and top board 1 are made by graphite material.Be provided with horizontal positioning device and perpendicular positioning device between base plate 5 and top board 1, base plate 5 is provided with product groove 11, and product 2 is loaded in the product groove 11, and top board 1 is provided with and product groove 11 corresponding through holes 7, is equipped with copper post 3 in the through hole 7.Product groove 11 and through hole 7 corresponding with it have a plurality of, by rectangular array.
Described horizontal positioning device comprises two base plate location holes 13 being positioned on the base plate 5, is positioned at two top board location holes 9 and two reference columns 2 on the top board 1, and reference column 2 matches with base plate location hole 13 and top board location hole 9.Reference column 2 is a multidiameter, and its small diameter portion matches with top board location hole 9, and its major diameter part matches with base plate location hole 13.
Perpendicular positioning device among the present invention has two kinds of embodiment:
Fig. 1～Fig. 3 is first kind of embodiment, and it comprises step 10 that is positioned at base plate 5 edges and the projection 6 that is positioned at top board 1 edge, and projection 6 is pressed on the step 10 during assembling.
In order to make the perpendicular positioning device assembling between base plate 5 and the top board 1 simple and convenient, be provided with chamfering 12 in the turning point of step 10, be provided with fillet 8 in the turning point of projection 6, chamfering 12 matches with fillet 8.
