As further improving and supplementing technique scheme; the utility model adopts following technical measures: the tail end of described plug overcoat is provided with rubber protecting jacket; described rubber protecting jacket is provided with through hole, and described cable enters into plug overcoat inner chamber through rubber protecting jacket.Epoxy resin is filled in the inside of plug overcoat, between plug overcoat and cable, assembles rubber protecting jacket, and to prevent cable, position sideslip is by plug overcoat when the encapsulating, and cable weares and teares when use.
Ringwise, in it, along the contact pin that is provided with degree of turning up, described contact pin is provided with connecting hole to described ground connection packing ring.
Be connected with ground connection packing ring in order to make to insert spring, the sidewall of described slotting spring is provided with the joint pin of evagination, and described joint pin and connecting hole are pegged graft.
Reliable in order to assemble, and can make ground connection packing ring firmly be arranged between rubber sheath and plug overcoat, the position being connected with plug overcoat on described rubber sheath is step, described step is made up of accepting bulge loop and standing on the overlap joint ring of accepting on bulge loop of evagination, it is upper that described plug overcoat and ground connection packing ring are all fastened in overlap joint ring, and ground connection packing ring is close to accept bulge loop.
In order to improve compression reliability, described plug overcoat is provided with flanging with the end that ground connection packing ring contacts, and described flanging is close to ground connection packing ring.
In order to make external shape neatly reasonable, described in accept bulge loop and flanging outer flush with the outer of ground connection packing ring.
The beneficial effect the utlity model has: 1, set up ground connection packing ring and slotting spring between rubber sheath and plug overcoat, ground connection packing ring is connected, the object being grounded with slotting spring with earth connection.2, epoxy resin is filled in the inside of plug overcoat, between plug overcoat and cable, assembles rubber protecting jacket, and to prevent cable, position sideslip is by plug overcoat when the encapsulating, and cable weares and teares when use.3, reliable in order to assemble, and can make ground connection packing ring firmly be arranged between rubber sheath and plug overcoat, arrange and accept bulge loop and flanging, make to accept bulge loop and flanging and compress ground connection packing ring, avoid ground connection packing ring to rotate or move, improve dependability.
