Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, shown in 2, a kind of sealed type binding post, comprise through installing hole, the binding post 10 of connected chamber inside and outside, described binding post 10 matches with insulating sleeve 20 size and is arranged in insulating sleeve 20, described insulating sleeve 20 matches with installing hole size and is arranged in installing hole, the station matching relationship of axial free movement is construed as limiting at downside binding post 10 and the insulating sleeve 20 of installing hole, fastening by nut I 30 at the described insulating sleeve in the upside of installing hole 20, described binding post 10 is fixed on insulating sleeve 20 by nut II 31, and the sealing of binding post 10 and insulating sleeve 20 is realized by sealing ring II 41, the cable of described binding post 10 upper and lower end is realized by packing ring 50 and nut IV 33 and being fastenedly connected of binding post 10 all successively.
Nut I 30 for screw thread fixed insulation sheath 20 is set to double nut, and described double nut is the first nut 301 in the side near installing hole, opposite side is the second nut 302.
Other conductive body and binding post 10 are isolated by described insulating sleeve 20 and the first nut 301, and insulating sleeve 20 and the first nut 301 realize the sealing of installing hole by upper sealing ring 42 and lower seal 43.
Described binding post 10 is also fixed sealing by adding packing ring 50 on nut II 31 successively with nut III 32 is auxiliary.The cable that described binding post 10 upper end is fastened on nut III 32 realizes being fastenedly connected by packing ring 50 and nut IV 33 successively; Equally, the described binding post 10 lower end cable be fastened on the downside of it passed through packing ring 50 successively and realizes being fastenedly connected with nut IV 33, and wherein binding post 10 realizes sealing by sealing ring I 40 with insulating sleeve 20.
