Embodiment

To shown in Figure 7, a kind of electric connector secondary connecting element that the utility model discloses comprises male plug body 1, female plug body 2, male plug pin 3, female plug pin 4, clasp 5, male plug body cover plate 6, female plug body cover plate 7 and contact pin cover plate 8 as Fig. 1.

Male plug pin 3 and female plug pin 4 are separately fixed in the pin holes of male plug body 1 and female plug body 2 correspondences.

Be covered with the contact pin cover plate 8 that prevents that male plug pin 3 and female plug pin 4 from withdrawing from male plug body 1 and the female plug body 2 separately.Assembling for convenience, as shown in Figure 3, back-off 11 in this embodiment respectively forms in male plug body 1 forms side opening 81 on the contact pin cover plate 8, contact pin cover plate 8 is by side opening 81 and 11 cooperations of interior back-off and be fixed on male plug body 1, and both cooperations can make male plug pin 3 firmly fix.In like manner, the fit structure of female plug body 2 and contact pin cover plate 8 also is like this, does not do at this and gives unnecessary details.Referring to shown in Figure 8, if profile is rectangle, the male plug body cover plate 6 of male plug body 1 and female plug body 2 female plug body cover plates 7 share, and just do not need contact pin cover plate 8.

Male plug body cover plate 6 and female plug body cover plate 7 are separately fixed on the outside of male plug body 1 and female plug body 2, play sealing process.Assembling for convenience, as shown in Figure 2, this embodiment is back-off 22 outside the front end of female plug body 2 forms, and the front end of female plug body cover plate 7 forms open front 71; The end of female plug body 2 forms after-opening 23, and the end of female plug body cover plate 7 forms trip 72; During assembling, at first the trip 72 with female plug body cover plate 7 ends inserts in the after-opening 23 of female plug body 2 ends, then female plug body cover plate 7 front ends are down pressed, the outer back-off 22 of female plug body 2 front ends just is stuck in the open front 71 of female plug body cover plate 7 front ends, so just can realize interfixing of female plug body 2 and female plug body cover plate 7; If when both are separated, need elder generation that the outer back-off 22 of female plug body 2 front ends is prized from the open front 71 of female plug body cover plate 7 front ends, namely separable.The fit structure of male plug body 1 and male plug body cover plate 6 also is like this, does not do at this and gives unnecessary details.In addition, it is the same with female plug body cover plate 7 that male plug body cover plate 6 can be made, and namely male plug body 1 and female plug body 2 share a cover plate, and the utility model separates both for attractive in appearance.

Clasp 5 is hubbed on the side of male plug body 1, and the upper end of clasp 5 forms cam 52 and draw-in groove 53 for 51 lower ends, operating side, and the corresponding cam 52 in the side of female plug body 2 and draw-in groove 53 form convex clip 21.For further simplified structure, be convenient to operation, as shown in Figure 4, the clasp 5 of this embodiment is the Jiong type, end floor beam is operating side 51 on the clasp 5, operating side 51 forms curved flanges, when will unclamp clasp 5, hand can lean against this position, clasp 5 below two side arms form bayonet socket 54, form the boss 12 corresponding with clasp 5 bayonet sockets 54 shapes on the side of male plug body 1, when clasp 5 is installed, need earlier that the bayonet socket 54 of clasp 5 is consistent with the boss 12 maintenance directions of male plug body 1, break clasp 5 then into two with one's hands, rely on strain to make bayonet socket 54 drop in the boss 12 of male plug body 1, install clasp 5 after, clasp 5 just is hubbed on the side of male plug body 1, can be around boss 12 rotations on the male plug body 1.In order to make operation more smooth and easy, as shown in Figure 5, the slewing area of this embodiment corresponding clasp 5 on the side of female plug body 2 forms the projection 24 concordant with male plug body 1 side, can prevent effectively that like this clasp 5 from producing distortion in the process of snap close, and make front end 55 be anchored on the end face 25 of female plug body 2.Use for operation better, this embodiment is the gradual change arc with 53 designs of clasp 5 front end draw-in grooves, makes when clasp 5 unclamps at the cam 52 of clasp 5 and formation free-runing operation state before the convex clip 21 of female plug body 2 contacts.In addition, this embodiment male plug body 1 side also forms for unclamping the spacing protruding grain 13 in back with clasp.

When the utility model uses, rotate clasp 5, convex clip 21 slips in the draw-in groove 53 and cooperates, and clasp 5 fastenings are on female plug body 2,2 pairs of male plug body 1 and female plug bodies are inserted, if counter-rotation clasp 5, convex clip 21 withdraws from draw-in groove 53, simultaneously, cam 52 is taken advantage of a situation and is promoted convex clip 21, clasp 5 unclamps female plug body 2, and male plug body 1 and female plug body 2 also unclamp, and separates.Therebetween, when convex clip 21 withdrawed from gradual change arc area to clasp 5 front ends, convex clip 21 did not patch with clasp 5 camber lines, and this moment, clasp 5 was in the free-runing operation state; When free-runing operation to convex clip 21 contacts with cam 52, take downward mode by clasp 5 operating sides 51 to make male plug body 1 and female plug body 2 unclamp, studies show that this mode of employing can be more laborsaving, when when contacting to clasp 5 and male plug body 1 side protruding 13, down press this moment again, clasp 5 drives male plug body 1 and forms heeling condition together, and this mode is convenient to separate male plug body 1 and female plug body 2.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
