Abstract

The utility model relates to a puncture clamp applicable in the environment with a high temperature, humidity and pressure. The puncture clamp of the utility model comprises a clamp body upper cover and a clamp body lower cover. The clamp body upper cover and the clamp body lower cover are connected via bolts. A torque force cap (3) is provided for each bolt, and used to clamp or relax the clamp body upper cover and the clamp body lower cover by turning the torque force cap (3). An arc insulated copper tooth sheath is provided on one side of the clamp body upper cover, and another on the other side of the clamp body lower cover to form two parallel wiring slots. The copper tooth sheath (5) is provided with copper teeth on the external side. The utility model has reliable solidity and tightness, does not easily have electric leakage, and has a strong anti-breakdown ability. Besides, the utility model is simple in structure, durable, solid and reliable, and thus greatly extends the service life of the puncture clamp.

Description

Penetrating cable clamp

Technical field

The utility model relates to the jockey of a kind of high and low pressure electric power connection area, be applicable to being connected of leading body and branch, the connection of high and low pressure insulated wire, and the connection of distribution system branch, particularly a kind of penetrating cable clamp that is applicable under high temperature, high humidity and the hyperbaric environment.

Background technology

Along with the popularization of suspended insulated guide wire, the insulating properties, the reliability that T are connect metal have had higher requirement.Yet known penetrating cable clamp insulation property are bad, the product structure weak strength, and torsion is inhomogeneous.From actual working environment the requirement of product there is very big gap.Especially in particular surroundings: under high temperature, high humidity and hyperbaric environment, because its internal structure is loose and coarse, its product damages easily, even leads to a disaster.

Summary of the invention

The purpose of this utility model is that easy puncture, insulation property and sealing property that existing product exists are bad, torsion is very inhomogeneous, the flimsy shortcoming of loose and rough in order to overcome, and a kind of sound construction, good insulation preformance are provided, can easily be applied to the penetrating cable clamp under the environment of high temperature, high humidity and high pressure.

The utility model is to realize by following technical scheme: penetrating cable clamp described in the utility model, comprise wire clamp main body lower cover and wire clamp main body loam cake, wire clamp main body lower cover and wire clamp main body loam cake connect as one by bolt, bolt is provided with torsion cap 3, the rotary torsion cap can make wire clamp main body lower cover and wire clamp main body loam cake clamp or unclamp, the side that online clip main body lower cover is relative with wire clamp main body loam cake, one the first from left right side respectively be provided with two arc insulated copper tooth sheaths, constitute the connecting groove that twice are parallel to each other, be provided with the copper tooth in the outside of copper tooth sheath 5.

Described copper tooth is connected with the structure of copper tooth sheath with injection moulding process; Copper tooth sheath is connected with the structure of injection moulding process with wire clamp main body lower cover, wire clamp main body loam cake; Described torsion cap adopts the aluminum cold-extrusion technology to make.

Good effect of the present utility model is as follows: because the copper tooth is connected with the structure of copper tooth sheath with injection moulding process, copper tooth sheath is connected with the structure of injection moulding process with wire clamp main body line clip main body lower cover, wire clamp main body loam cake, so greatly strengthened the fastness of wire clamp and the reliability of sealing, and be difficult for leaking electricity, breakdown characteristics is strong, under the situation of rated current and short circuit, heating up in the wire clamp surface not to be higher than the temperature of bonding conductor; The 30cm place under the environment of 6kv, continues 1 minute under water, can be not breakdown; The torsion cap adopts aluminum cold-extrusion technology, the average level and the useful life of having improved torsion greatly; The copper tooth 4 of particular design is used to connect copper or aluminum line, and the exterior insulation protective layer adopts high-intensity glass fibre polymeric material to make, and need not to remove insulating barrier during use; The utility model is simple in structure, and is durable in use, solid and reliable, greatly improved the useful life of penetrating cable clamp.

Embodiment

As shown in Figure 1, penetrating cable clamp described in the utility model, comprise wire clamp main body lower cover 1 and wire clamp main body loam cake 2, wire clamp main body lower cover 1 and wire clamp main body loam cake 2 connect as one by bolt 7, bolt 7 is provided with torsion cap 3, rotary torsion cap 3 can make wire clamp main body lower cover 1 and wire clamp main body loam cake 2 clamp or unclamp, the side that online clip main body lower cover 1 and wire clamp main body loam cake 2 are relative, one the first from left right side respectively be provided with two arc insulated copper tooth sheaths 5, constitute the connecting groove 6 that twice are parallel to each other, be provided with copper tooth 4 in the outside of copper tooth sheath 5.

Described copper tooth 4 is connected with the structure of copper tooth sheath 5 with injection moulding process; Copper tooth sheath 5 is connected with the structure of injection moulding process with wire clamp main body lower cover 1, wire clamp main body loam cake 2; Described torsion cap 3 adopts the aluminum cold-extrusion technology to make.

During use, with 6 li of the parallel connecting grooves of putting into wire clamp with sub-conductor of leading body, tighten torsion cap 3 then, make wire clamp main body lower cover 1 and wire clamp main body loam cake 2 clamp leading body and sub-conductors, the insulating barrier that copper tooth 4 pierces through two conductors simultaneously connects their.
