Abstract
The utility model relates to an insulating strain clamp of NXJ, including wedge strain clamp body, the inside wedge clamp that is provided with of wedge strain clamp body, wedge strain clamp body outside is provided with the link plate, the butt joint is fixed each other through the interlock structures who sets up in its lower part for the wedge clamp, interlock structures is at least a pair of setting and is in wedge clamp lower part opposition block mechanism on the surface. The insulating strain clamp of this kind of structure is adopted, wedge clamp fixed connection can be strengthened to prevent its dislocation or removal.
Description
Technical field
The utility model belongs to electric armour clamp technical field, is specifically related to a kind of NXJ insulating tension clamp.
Background technology
Strain clamp is for fixed cable, to bear cable strain, and hangs cable to the gold utensil in strain insulator-string group or shaft tower.Strain clamp, by the difference of structure and mounting condition, can be divided into two classes: first kind strain clamp will hold whole pulling force of wire, lightning conducter and bracing wire, and grip of clamp should be not less than 90% of mounted wire or the specified stretching resistance of lightning conducter, but does not make conductor.This kind of wire clamp has bolt-type strain clamp and wedge strain resistance cable clamp.The feature of such wire clamp can pull down after wire is installed, and uses separately; Equations of The Second Kind strain clamp except will holding wire and the whole pulling force of lightning conducter, again as conductor.This kind of wire clamp feature can not dismantle after installing, and presss from both sides also known as dead wire.Wherein, wedge strain resistance cable clamp makes according to " wedge " principle design.Under power of the splitting effect of wedge, steel strand wire are locked in wire clamp.When steel strand wire are installed to after in wire clamp, pull steel strand wire, chock and steel strand wire will export slippage along wire clamp barrel to wire clamp simultaneously, and more draw tighter, gradually in locking state.The feature of wedge strain resistance cable clamp is that installation and removal is convenient, and after wire clamp installs, wire clamp outlet termination and load line or can adopt steel wire clamp to be fixed at tangent point termination with No. 8 galvanized iron wire tightens.
Chinese patent 03210522.3 discloses a kind of four-core centralized cable strain clamp, and the core that this strain clamp utilizes two voussoirs coordinated in pairs to clamp cable penetrates tensioning in the wedge cavities of wire clamp again.The shortcoming of this strain clamp to be used for the tensioning to four-core centralized cable, cannot carry out tensioning to the cable of other core numbers.
Chinese patent 201110334211.5 discloses a kind of wedge-shape strain clamp of bunched cable.This strain clamp is made up of the clamp and the voussoir be arranged in wedge cavities being provided with wedge cavities, and its voussoir is monolithic construction, and the narrow wall in voussoir both sides is provided with clamp groove.The shortcoming of this strain clamp is the stress balance that voussoir both sides must accompany that cable adopts guarantee voussoir simultaneously, and namely this wire clamp can only be used for the tensioning with paired core cable.
For above-mentioned deficiency, need develop a kind of wedge strain resistance cable clamp, it uses and by the restriction of cable core number, to improve the scope of application of wedge strain resistance cable clamp, should not prevent the problem of wedge clamp dislocation or slippage.
Utility model content
For solving the problem, the utility model provides a kind of NXJ blood group strain clamp effectively preventing wedge clamp dislocation or relative movement.
Realizing the technical solution of the utility model is: a kind of NXJ insulating tension clamp, comprise wedge strain resistance cable clamp body, described wedge strain resistance cable clamp body interior is provided with wedge clamp, described wedge strain resistance cable clamp body exterior is provided with link plate, described wedge clamp docks fixing by being arranged on the interlocking structure of its underpart each other, and described interlocking structure is that at least one pair of is arranged on the snap fastener of described wedge clamp counter surface bottom.
As preferably, the number of described wedge clamp is two, and described two wedge clamps are wedge clamp A and wedge clamp B respectively, and the opposed contact surface bottom of described wedge clamp A and wedge clamp B is provided with boss, and described boss is provided with snap fastener.
As preferably, the logarithm of described snap fastener can be provided with one or more pairs of.
As preferably, described snap fastener is made up of embeding mechanism and subtend embeding mechanism.
As preferably, described embeding mechanism is the elastic card component be arranged on for a pair on the boss of wedge clamp A, and the direction of described elastic card component is stretched out towards the boss of wedge clamp B; Described subtend embeding mechanism is be arranged on the perforate on the boss of wedge clamp B, for being fitted together to for described a pair fastener.
As preferably, the end of described elastic card component has at least one outwardly directed hook-shaped spur, and described perforate is provided with the trailing edge that mutually can lock with described hook-shaped spur.
The utility model arranges interlocking structure by the opposed contact surface bottom at wedge clamp A and wedge clamp B, dislocation can not occur and move when being two wedge clamp contact connections.
