Embodiment

Below in conjunction with accompanying drawing, the utility model water-proof connector is described in further detail.

As shown in Figures 1 to 7, the utility model water-proof connector will be inserted in afterbody water proof ring 2 on the wire rod 8 of the anti-head male end body of injection moulding or forming 7 and anti-head female end body 3, after packaging, be torqued into afterbody blind nut 1, under the torsion of afterbody blind nut 1, make afterbody water proof ring 2 be filled in fully wire rod 8 and anti-head male end body 7 and anti-head female end body 3 afterbodys.In the spring groove 7d of anti-head male end body 7, pack spring 6 into, then by nut 4 the fool proof mouth 7c along anti-head male end body 7, pack in anti-head male end body 7.The anti-head male end of disposable injection moulding body 3 and anti-head female end body 7 on request, anti-head male end body 7 is provided with fool proof mouth 7a, loading port 7c, slip-off preventing limit 7b, fixed edge 7f, spring groove 7d design, cost-saving, and in the time that loading port 7c twists counterclockwise, the triangle tilt clamping hook 7e of loading port, block the salient point 4a on nut 4, nut 4 can not be to clockwise shearing, salient point 4a on nut 4 is also stuck in spring 6 in spring groove 7d, can not eject arbitrarily, position, top nut 4, be stuck on anti-head male end body 3 triangle tilt clamping hook 7e, can not exit, be that nut 4 forms an entirety with anti-head male end body 3.Nut 4 is packed in anti-head male end body 7, and nut 4 forms an assembly with anti-head male end body 7, and nut 4 front ends are provided with three or above oblique salient point 4b, and tiltedly salient point 4b is identical with the grab 3a gradient of anti-head female end body 3.Water proof ring 5 is inserted in port at anti-head male end body 7.Outside anti-head female end body 3, be arranged with three or above grab 3a, inside is provided with fool proof mouth 3c, fool proof while plug with anti-head male end body 7, centre is provided with isolation shelves wall groove 3b, prevent withstand voltage and safety is bad, the isolation shelves wall 7j of isolation shelves wall groove 3b and anti-head male end body 7, forms convex-concave interworking, increases electrical safe, withstand voltage and safety distance.Anti-head male end body 7 inside are provided with isolation shelves wall 7j, an inner side is also provided with fool proof mouth 7h, fool proof mouth 3c, the isolation shelves wall groove 3b of isolation shelves wall 7j, fool proof mouth 7h and anti-head female end body 3 form convex-concave interworking, increase electrical safe, withstand voltage and safety distance.When anti-head male end body 7 inserts anti-head female end body 3, 3 or above oblique salient point 4b of nut 4 front ends, identical with the grab 3a gradient of anti-head female end body 3, mutual interior top mutually, compressing water proof ring 5, now, nut 4 is along moving counterclockwise, when water proof ring is oppressed when a certain amount of, oneself exceedes the peak 3c of anti-head female end body 3 grab 3a the peak 4c of the oblique salient point 4b of nut 4 front end, just in surmounting peak, under the elastic force effect of spring 6, blind nut 4 is again to clockwise motion, snap in the U-shaped draw-in groove 3d of anti-head female end body 3, allow water proof ring be filled in fully between anti-head male end body 7 and anti-head female end body 3, allow anti-head male end body 7 and anti-head female end body 3 seamless waterproof.Nut 4 is under the elastic force effect of spring 6, blind nut grab 4a blocks in the U-shaped draw-in groove 3d that expands anti-head female end body 3 firmly, in the time that torsion moves counterclockwise, the peak of nut 4 exits the peak 3c of anti-head female end body 3, divide again and easily separate anti-head female end body 3 and anti-head male end body 7, realize plug convenient.Nut 4 forms an entirety with anti-head male end body 3, before anti-head female end body 3 and anti-head male end body 7, be equivalent to have three or above grab to fix, be that 3a is with tiltedly salient point 4b is firmly fixing, so there are 3 or above grab, anti-head female end body 3 is equivalent to stressed even with anti-head male end body 7, be that water proof ring 5 can not cause distortion uneven because being subject to the effect of external force, Gu can ensure anti-head female end body 3 and anti-head male end body 7 waterproof before, guaranteed quality.

According to above-mentioned design of the present utility model, those skilled in the art also can make to this various amendments and conversion.But similar this conversion and amendment all belong to essence of the present utility model.
