Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of British connecting plug with novel internal frame, comprise the interior frame body 2 be arranged in header body 1 and the fuse cavity 21 being positioned at frame body 2 front end, fuse cavity 21 is installed for fuse 7 and fuse protecting cover 71.The front end of described interior frame body is provided with inserted sheet 3, specifically include zero line inserted sheet 31 successively, live wire inserted sheet 32 and ground wire inserted sheet 33, the position of the corresponding fuse cavity 21 in rear end of described interior frame body 2 is provided with lug boss 22, copper tip 4 is then installed in the rear end of described interior frame body 2, specifically include the zero terminal 41 be connected with zero line inserted sheet 31 successively, hot terminal 42 on the left of one end access fuse cavity 21, the ground wire terminal 43 be connected with ground wire inserted sheet 33 and live wire filling-in bit terminal 44, wherein said zero terminal 41, the other end of hot terminal 42 and ground wire terminal 43 extends to the lower end of interior frame body 2 as riveted joint line end, the riveted joint line end of copper tip 4 so just can be made to concentrate on a place and arrange in line, one end of described live wire filling-in bit terminal 44 is connected with live wire inserted sheet 32, the other end of described live wire filling-in bit terminal 44 then accesses on the left of fuse cavity 21, described hot terminal 42 and live wire filling-in bit terminal 44 are each passed through on rear side of lug boss 22 left, right two ends access fuse cavity 21.
The middle of described hot terminal 42, ground wire terminal 43 and live wire filling-in bit terminal 44 is provided with the lower turnover position 45 being adjacent to lug boss 22 lower surface, be adjacent to lug boss 22 upper end surface in the middle of described ground wire terminal 43 and be also provided with turnover position 46, this design had both been conducive to reducing the space shared by copper tip 4, also make copper tip 4 install more firm, avoid occurring dislocation during rivet line.
The rear end of described interior frame body 2 be disposed with for separate zero terminal 41 and hot terminal 42 part dividing plate 5 on the left side, separate demarcation strip 51, separatedly line terminals 43 and live wire filling-in bit terminal 44 in hot terminal 42 and ground wire terminal 43 part dividing plate 52 on the right side, the described lower end parting dividing plate 5, middle demarcation strip 51 on the left side and part dividing plate 52 on the right side extends to interior frame body 2 lower end, and the described upper end parting dividing plate 5, middle demarcation strip 51 on the left side and part dividing plate 52 on the right side extends to the upper end of lug boss 22.The design of dividing plate not only improves the steadiness of interior frame body 2, and the buffer action between playing each copper tip 4, is conducive to saving space in plug.The described dividing plate 5 that parts on the left side is positioned at lug boss 22 place and has the bulkhead apertures 53 passed for hot terminal 42, makes hot terminal 42 avoid displacement when rivet line.
The rear end of described interior frame body 2 is provided with pressure cap 6, and the two ends, left and right, lower end of described interior frame body 2 and the two ends, left and right of ground wire inserted sheet 33 junction are respectively arranged with jack 23, and in described pressure cap 6 is corresponding, the position of the jack 23 of frame body 2 is provided with back-off part 61.The position of the lower end, respective protrusions portion 22, front end of described interior frame body 2 is provided with supporting bracket 62.Pressure cap 6, particularly engage 62 structure, can play the effect of the compression strength of frame body 2 in strengthening.
When actual production, its step is as follows:
1. power line 8 is through peeling opening, carries out disposable riveting operation with the copper tip 4 above interior frame body 2;
