Description
Technical field
The utility model relates to a kind of wedge strain resistance cable clamp.
Background technology
Strain clamp is the termination for fixing cord, and bears the gold utensil of wire tension, is mainly used in fixing cord and lightning rod on the insulator string of strain insulator, corner, terminal shaft tower.Strain clamp has two classes, and first kind strain clamp only bears whole pulling force of wire, lightning conducter and bracing wire, but does not make conductor; Equations of The Second Kind strain clamp is except bearing the whole pulling force of wire and lightning conducter, again as conductor.Wedge strain resistance cable clamp belongs to the wire clamp that the first kind is only born tension force, is to make according to " wedge " principle design.Wedge cavities is set in wire clip body, and wedge is clamped steel strand wire.After steel strand wire are installed in wire clamp, pull steel strand wire, wedge and steel strand wire export slippage by while wedge cavities along the line to wire clamp, and more draw tightlyer, are gradually locking state.When pulling steel strand wire, between wedge and steel strand wire, must keep enough frictional force, just can make wedge and steel strand wire along wedge cavities, move simultaneously, when wedge and steel strand wire frictional force deficiency, pulling steel strand wire to produce looses core, be that steel strand wire integral body from wedge skids off, and affect wire clamp, normally use.Therefore,, for guaranteeing the normal use of wedge strain resistance cable clamp, must increase the frictional force between wedge and steel strand wire.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of wedge strain resistance cable clamp, can increase the frictional force between wire and wedge, and during bracing wire, wire can not produce and loose core.
Wedge strain resistance cable clamp of the present utility model, comprises body, left and right wedge and pull bar; Described body is provided with wedge cavities, and described left and right wedge is positioned at wedge cavities and slides before and after wedge cavities surface; Described pull bar two ends are connected on the body of the larger side of wedge cavities opening, form closed circular with body, two faces that described left and right wedge is relative are provided with half slot, the clamp hole connecting before and after two half slots form, in described two halves circular groove, be provided with vertically a row hemi-spherical granule, described two row particles are positioned on the same median plane in clamp hole and are staggered front to back layout.
Further, rear and front end, described clamp hole is bellmouth, and shrink to middle part by clamp bore ends in the cross section of described two bellmouths, is provided with the taper briquetting being slidably matched with bellmouth in described bellmouth, and described briquetting middle part is provided with the hole that can wear wire.
Further, described briquetting end is provided with disk, and disk side is extended with circle cover towards body direction, and described circle puts and is provided with internal thread, and described body is provided with the external screw thread matching with circle cover inner periphery screw thread.
The beneficial effects of the utility model: wedge strain resistance cable clamp of the present utility model, comprises body, left and right wedge and pull bar; Described body is provided with wedge cavities, and described left and right wedge is positioned at wedge cavities and slides before and after wedge cavities surface; Described pull bar two ends are connected on the body of the larger side of wedge cavities opening, form closed circular with body 1, and insulator etc. are arranged on pull bar.Two faces that described left and right wedge is relative are provided with half slot, the clamp hole connecting before and after two half slots form, the diameter in clamp hole is less than wire diameter to be pressed from both sides, wire is placed in left and right wedge in clamp hole and fully wire is compressed, in described two halves circular groove, be respectively provided with vertically a row hemi-spherical granule, described two row particles are positioned on the same median plane in clamp hole, and be staggered front to back layout, two row particles of interlaced arrangement compress wire to be wavy, wavyly make between wire and wedge to produce larger tensile force, increase the frictional force between wire and wedge, during bracing wire, wire can not produce and loose core.
Accompanying drawing explanation
