Abstract
The utility model discloses a strain clamp for an aluminium-alloy core aluminum stranded conductor, and relates to power equipment. The exit end of an aluminium pipe of the strain clamp is provided with a taper which has conicity. A steel anchor is disposed at the rear end of the aluminium pipe. The front end of the steel anchor is provided with a plurality of annular grooves. The rear end of the aluminium pipe is provided with an aluminium pipe drainage plate which is connected with an equipment wire clamp through a bolt, thereby forming the drain clamp. The strain clamp is simple in structure, is low in cost, and is convenient for engineering application. The exit end of the aluminium pipe of the strain clamp is provided with the taper which has conicity, thereby improving the retention rate of crimping strength of a wire, and increasing the pulling strength. A crimping tension test value is greater than the 95% of a designed collapsing force, so that the drain clamp can complete the connection of wire with a tower safely and reliably.
Description
Technical field
The utility model relates to a kind of power equipment.
Background technology
Aluminum stranded wire of aluminum alloy core, as a kind of novel energy-conserving wire, is advocated and is applied energetically.But, the strain clamp not matching when the type wire is connected with shaft tower at present, if apply mechanically the strain clamp of other type wire, as conventional steel reinforced aluminium conductor strain clamp, the steel anchor of this wire clamp is hollow, steel anchor post is smooth structure, and whole aluminum pipe is hollow cylindrical structure, due to the difference of conductor structure pattern, be difficult to coupling completely, even substantially coupling, the pull-off force after crimping does not reach instructions for use yet, thus be aluminum stranded wire of aluminum alloy core installing rack tape difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminum alloy core aluminum stranded wire strain clamp, to solve the strain clamp not matching when prior art does not have aluminum stranded wire of aluminum alloy core to be connected with shaft tower, apply mechanically the strain clamp of other type wire, due to the difference of conductor structure pattern, be difficult to coupling completely, even coupling substantially, the pull-off force after crimping does not reach the problems such as instructions for use yet.
The utility model is mainly made up of aluminum pipe, steel anchor, aluminum pipe drainage plate and device clamp, and solving the technical scheme that its technical problem adopts is that aluminum pipe is hollow-core construction, and the aluminum pipe port of export is that the tapering pulling out is slightly that 1:7 is to 1:8 with the pulling out slightly of tapering; Taper length is 3 times of wire diameter; Steel anchor is placed in aluminum pipe rear end, and steel anchor is solid construction, and steel anchor front end arranges some cannelures, and aluminum pipe drainage plate is set on aluminum pipe rear end, and aluminum pipe drainage plate is connected with device clamp by bolt, forms strain clamp.Aluminum pipe and pull out and slightly form polygonized structure after aluminum stranded wire of aluminum alloy core and strain clamp crimping.
It is simple in structure adopting good effect of the present utility model, with low cost, facilitates engineering application.The aluminum pipe outlet section of this strain clamp is the taper with tapering, has improved conductor compression jointing strength retention ratio, has increased pull-off force, and crimping pull test value is greater than 95% of design, destroy power, can be safe and reliable complete being connected of wire and shaft tower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Accompanying drawing 1 is the utility model structural representation;
1 taper, 2 aluminum pipes, 3 steel anchors, 4 aluminum pipe drainage plates, 5 device clamps, 6 cannelures in figure.
Embodiment
As shown in the figure: the aluminum pipe 2 of this wire clamp is hollow-core construction, aluminum pipe 2 ports of export be with tapering pull out slightly 1, taper 1 length is wire diameter 3 times; Steel anchor 3 is placed in aluminum pipe 2 rear ends, and steel anchor 3 is solid construction, and steel anchor 3 adopts 10# carbon constructional quality steel, steel anchor 3 front ends arrange five groups of cannelures 6, aluminum pipe arranges aluminum pipe drainage plate 4 on 2 rear ends, and aluminum pipe drainage plate 4 is connected with device clamp 5 by bolt, forms strain clamp.Aluminum pipe and pull out and slightly form polygonized structure after aluminum stranded wire of aluminum alloy core and strain clamp crimping.The structure of device clamp, aluminum pipe drainage tube is identical with conventional steel reinforced aluminium conductor device clamp with material.
