Abstract

The utility model discloses an extruding wire clamp which is composed of a female jacket and a male jacket whose inner circular arc slot is provided with a slope, and the diameter of the inner circular arc slot of the female jacket is the same with the outside diameter of a conducting wire. The male jacket is pressed into the female jacket to accomplish joint by the conducting wire. The extruding wire clamp is suitable for connecting and patching electric power transmission wires with various types and standards, and the extruding wire clamp does not need mechanical compression joint and explosion compression joint.

Description

Extruding wire clamp

The utility model relates to a kind of wire clamp that all kinds of power mains are used that connects.

The built on stilts electric line of generating, transmission of electricity, power transformation and electricity consumption, and the connection of steel strand lightning conducter and repairing all needs a large amount of wire clamps, its internal diameter of used wire clamp all bigger than lead, during construction, lead pack into mother set, build public cover, again with pincers pressure, hydraulic machinery or with the method for exploding, lead and wire clamp are pressed into an integral body, realize connecting.Method is loaded down with trivial details, needs special equipment or explosive, and quality is also not enough good.

The purpose of this utility model is to propose a kind ofly to use simple method to replace mechanical crimping to be connected the wire clamp of transmission pressure connection with the explosion crimping method.Construction is simple, ensures the quality of products.

The Extruding wire clamp that the utility model proposes is made up of public affairs covers and mother set, and a step is arranged on the mother set lnner arced slot, and the diameter of circular arc is lucky consistent with the external diameter after lead is stressed.The arc groove of its public cover has a corresponding step outward, and size, shape are just identical with the step of mother set.And the arc groove of public cover is a taper seat, and the public affairs cover is squeezed into mother set, just lead is compressed, and combines closely with wire clamp, the reinforcement that realizes lead with connection

Structure and effect below in conjunction with the description of drawings Extruding wire clamp.

Fig. 1 is the front view of Extruding wire clamp assembly.

Fig. 2 is the left view of Extruding wire clamp.

With reference to accompanying drawing, below the mother set (1) with the rectangular slab of three circular holes as drainage plate, be used for connecting service conductor to consumer. During construction, earlier lead is pressed in the arc groove (2) of mother set (1), the major part that then public affairs is overlapped the taper arc groove (2) of (4) inserts mother set (1), and step (6) coincide with step (3), the public affairs cover is all advanced mother set gradually, just realized the purpose of connection and reinforcement lead.

The Extruding wire clamp that the utility model proposes is processed by aluminium or steel.

The Extruding wire clamp that the utility model proposes is applicable to various aluminum stranded conductors, all models of steel-cored aluminium strand and the specification that standard GB/T 1179-74 and GB1179-83 announce. Also be applicable to all kinds steel strand wires that various lightning conducters are used.

The advantage of the Extruding wire clamp that the utility model proposes is to construct simple and convenient, and bag does not paste explosive and cap sensitive, and also special vice is not pressed and hydraulic test.Only just knock and can carry out with little Hammer head, the Extruding wire clamp cost is low, is lower than half of former usefulness wire clamp, does not also comprise the consumption of detonator, explosive or the machine power energy.Easy construction reduces labour intensity, the noise pollution of not exploding and producing again, favorable environment.

Claims

A kind of wire clamp that connects transmission pressure, form by public affairs cover and female overlapping, it is characterized in that on female cover [1] interior arc groove [2] step [3] being arranged, step [6] is arranged outside the arc groove [5] of public cover [4], step [6] just coincide with the size and the shape of step [3], and arc groove [5] is a taper seat.
