By adopting technique scheme, two hole walls are all fitted tightly with the side of close separately puncture blade, when can guarantee sealing property, prevent the outside run-off the straight of puncture blade of both sides, then affect the effect that punctures.
The utility model is further set to: described respectively puncture blade respectively with insulation upper cover and insulation lower cover one-body molded setting.
By adopting technique scheme, by each puncture blade respectively with insulation upper cover and insulation lower cover one-body molded setting, in by insulation upper cover and the injection mo(u)lding of insulation lower cover, directly puncture blade is cast in insulation upper cover and insulation lower cover, guarantee respectively puncture bonding strength and the stability of blade and insulation upper cover and insulation lower cover, thereby extended the useful life of described penetrating cable clamp.
The utility model is further set to: in described upper cushion cover and lower cushion cover, be all filled with glass fiber.
By adopting technique scheme, be filled with glass fiber and can make the pliability of two cushion covers better, in use, structural strength is higher, more durable in use, and can resist certain external world and destroy.
The utility model is further set to: in described two connecting portions, be equipped with elastic sheet metal, described two elastic sheet metals bend curved platy structure mutually dorsad.
By adopting technique scheme, two elastic sheet metals that mutually bend dorsad curved platy structure are set, can utilize elastic deformation and the recovery capability of elastic sheet metal, give puncture portion a support force, active force when electric wire pushes mutually in the puncture portion of two cushion covers of enhancing, thereby make two cushion covers and the laminating of electric wire surface tightr, sealing effectiveness is better; In addition, can also prevent that connecting portion from upspringing.
