In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of electric power insulating puncturing earthing clamp, comprises screw rod, upper limb body, lower limb body and contactor blade; Screw rod is fixed with lower nut through after upper limb body and lower limb body successively; The upper end of screw rod is provided with torque nut by bonding, is provided with the pad of ring-type between torque nut and upper limb body;
Upper limb body is umbrella; After screw rod passes the lower surface of upper limb body, the lower surface of upper limb body is divided into left part and right part; The left part of lower surface and right part are symmetrical arc; The lower surface of upper limb body and the upper surface of lower limb body symmetrical; The left part of upper limb body lower surface and the left part of lower limb body upper surface form left cavity, the right part of upper limb body lower surface and the right part of lower limb body upper surface and form right cavity; A waterproof end cap is installed in the ear hole of upper limb body side;
The lower surface of upper limb body and the upper surface of lower limb body are all provided with the rubber gasket of arc; Above, between limbs and rubber gasket, contactor blade is installed.
Contactor blade is four, and upper limb body and lower limb body install two respectively; Contactor blade all exposes the edge of a knife through rubber gasket.
The edge of a knife is zigzag, in the curved distribution in the end of contactor blade.
The warning piece of a ring-type is installed in the draw-in groove of torque nut.
Upper limb body and lower limb body are provided with anti-fall buckle; The anti-fall buckle of upper and lower limbs is that front and back are symmetrical.
Overall construction design of the present utility model is insulation and obturation, and without exposed metal/bare metal, the contactor blade that upper and lower limbs are arranged can tighten penetrating insulating layer of cable along with screw rod, thus makes cable and conductor contact, carries out branch's continued access; The rubber seal gasket ring voltage cable of arc is pierced around position simultaneously, and in housing, silicone grease overflows, and carries out insulation protection and water proofing property protection, protect therefore the utility model to have good insulating properties to the surrounding of cable.The utility model all arranges contactor blade up and down and jagged knife-edge design ensure that puncture effect, adopts the structural design of integrated symmetric, wire longitudinal pulling force ability is strengthened, and connects reliable.
