Abstract
The utility model relates to the technical field of electric power fittings, and especially relates to a wedge-type insulating strain clamp. The wedge-type insulating strain clamp comprises a housing, a hanging plate and two paired wedge blocks, wherein one outer side face of the housing is provided with a base, a buckle plate is disposed on the base in a hinged manner, the rear end of the buckle plate is provided with a plug, the front ends of the two wedge blocks are inserted into the housing, and the inner side of the rear ends of the two wedge blocks are provided with a limiting hole matched with the plug. The wedge-type insulating strain clamp is reasonable in structure and rapid to mount, a lead is clamped by the wedge blocks and inserted into the housing for fixing, the hanging plate is connected with a lead rod, and nuts of torquing bolts are synchronously rotated so as to enable the housing to clamp the two wedge blocks, thus to tightly connect with the lead; and the plug is inserted between the wedge blocks so as to enable the wedge blocks and the housing to maintain stable connection, thereby avoiding failure by looseness, caused by extension of the lead, of the clamp.
Description
Technical field
The utility model relates to electric armour clamp technical field, particularly contract type insulating tension clamp.
Background technology
Along with the progress in epoch and scientific and technological development, the also vigorous growth of China's power industry technologies, the construction of various power infrastructures has also entered brand-new developing period.And the problem existing in disconnected etc. use is resisted in circuit installation, line security, lightning protection, existing various electric armour clamps are proposed to higher requirement.Strain clamp is wherein for fixed cable, to bear the tension force between cable circuit, and by cable hang with string group or shaft tower on gold utensil.
Existing strain clamp generally adopts screw bolt-type and wedge strain resistance cable clamp, the wire clamp of the type can repeated removal use after installing on wire, wedge strain resistance cable clamp is wherein the contraction of sliding in adaptive cavity according to the slide block of wedge shape, and then drive and clamping wire design principle that it is locked.But current strain clamp still exists certain defect and deficiency, wire clamp can only carry out tensioner to single bunched cable, and its scope of application is limited; Wire clamp after installation is fixing by cable deadweight traction merely, there will be lax and obscission after certain hour, and periodic maintenance need to remove and install again, increases a lot of workloads to the operating personnel of high-altitude installation and maintenance.Therefore, be necessary current structure to improve to improve its serviceability.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of compact conformation, contract type insulating tension clamp easy to use are provided.
For achieving the above object, the utility model is by the following technical solutions:
Contract type insulating tension clamp described in the utility model, comprises the wedge of housing, link plate and two pairings, and a lateral surface of described housing is provided with pedestal, the hinged buckle that is provided with on pedestal, and the rear end of buckle is provided with plug; The front end of described two wedges inserts in housing, and the rear inside of two wedges has the spacing hole coordinating with plug.
Further, described plug is provided with adjusting bolt, and adjusting bolt is connected with the rear end of buckle.
Further, described hull outside is provided with some reinforcements, and some reinforcements are longitudinally uniformly distributed along housing.
Further, described link plate front end is arranged on the hangers of housing both sides, and link plate front end is provided with torque bolt.
Further, the curved setting in endoporus both sides of described housing, the lateral surface of two voussoirs is the arcwall face coordinating with housing endoporus, and embracing in line hole of two wedge inner sides is coated with anti-skidding coating.
The utility model beneficial effect is: the utility model is rational in infrastructure, quick for installation, two wedge clamps are clamped in rear insertion housing fixing by wire, link plate connects with line bar and synchronizes and rotates the nut of torque bolt, makes housing clamp two wedges and then closely be connected with wire; Plug inserts between voussoir and then makes to keep stable between voussoir and housing and is connected, and avoids the extension of wire to cause wire clamp Loose invalidation.
