Description

A kind of double-deck connector

Technical field

The present invention relates to field of connectors, particularly a kind of double-deck connector.

Background technology

Common common double-deck connector such as Fig. 1～shown in Figure 3 comprise insulating body 10, and two-layer some equidistant arrangements up and down, spliced eye independently are set on it; Corresponding each the spliced eye both sides of insulating body 10 rear end faces of corresponding each spliced eye are convexly equipped with guiding block 101; Upper strata lock pin body 20 and be embedded upper strata conducting terminal 30 on it is inserted in insulating body 10 rear end faces along guiding block 101; Intermetallic metal spacer 40 is arranged at lock pin body 20 outsides, upper strata; Lower floor's lock pin body 50 and be embedded lower floor's conducting terminal 60 on it is inserted in outside the upper strata lock pin body 20; Lock pin bonnet 70 is arranged at outside lower floor's lock pin body 50; Shield shell 80 covers at outside the insulating body 10.

Above-mentioned deisgn product forms by four big assembly groups are upright, and two ferrule assemblies are finished by two different automatons on the program, moulds shell inside by manually metal spacing block and two ferrule assemblies being packed into then and finishes finished product.There is following shortcoming in it: lock pin adopts split-type design, and separate component quantity is many, and the development cost height can not be finished assembling with machine is disposable, and the completed knocked down products part is by manually finishing, and efficient is low, and the cost height forms product fraction defective height.

Summary of the invention

The objective of the invention is to design a kind of double-deck connector, adopt the integral structure design, separate component quantity reduces, save hand process, reduce material cost, cost of labor, development cost simultaneously, better guaranteed product quality, met the requirement of enhancing productivity.

For achieving the above object, technical scheme of the present invention is:

A kind of double-deck connector, it comprises, insulating body arranges two-layer some equidistant arrangements up and down, spliced eye independently on it; The insulating body rear end face of corresponding each spliced eye is offered some terminal grooves at interval, and each terminal groove both sides is convexly equipped with guiding block; Some first conducting terminals comprise that fixed part reaches the docking section from fixed part is bent to form; Described fixed part correspondence is embedded at some terminal grooves of described insulating body rear end face, and the docking section is inserted in the spliced eye of insulating body upper strata; Some holders, the terminal groove of the corresponding described insulating body rear end face in top, one side is convexly equipped with some fixed teeth, and relative another side vertical direction arranges terminal groove; The guiding block that each holder is convexly equipped with along each terminal groove both sides of insulating body inserts, and fixed teeth is against the fixed part that is embedded at each first conducting terminal in each terminal groove; Some second conducting terminals comprise that fixed part reaches the docking section from fixed part is bent to form; Described fixed part correspondence is embedded at the terminal groove on the described holder, and the docking section is inserted in the insulating body lower floor spliced eye; Fixing bonnet comprises base and some lids of a side on the base end face, corresponding described each spliced eye of insulating body is set along the base length direction; Lid medial surface vertical direction is convexly equipped with some fixed teeth; Fixing back cover base is inserted in the insulating body rear end lower, and corresponding each holder of each lid inserts, and the fixed teeth on it is against the second conducting terminal fixed part that respectively is embedded at the holder terminal groove; Shield shell covers at outside the insulating body.

Further, arrange before and after the fixed part of described first, second conducting terminal is at interval, corresponding, described holder and fixedly the fixed teeth on the bonnet be length setting at interval.

Again, described holder and fixedly the side of bonnet establish projection, the groove that is clasped with this projection is established in the guiding block inboard that each terminal groove both sides of described insulating body are convexly equipped with.

Convex tendon is established in cap body both sides, described fixing back, and the fixed groove that is embedded for this convex tendon is established in described holder terminal groove both sides.

Beneficial effect of the present invention:

The present invention adopts the integral structure design, and separate component quantity reduces, and omits the working of plastics of a upper strata lock pin; Because adopting the integral type design, the sealing between two-layer is better, does not need intermediate spacers; Simultaneously, the integral structure design can be finished upper strata conducting terminal-gold thread with same machine and penetrate, assemble the plastic of two-layer centre then, wear a layer conducting terminal-gold thread again, assemble bonnet at last, only need wrap shield shell by hand after coming out, save three road hand process and one automaton operation; New design has reduced material cost, cost of labor, development cost simultaneously, has better guaranteed product quality, meets the requirement of enhancing productivity.
