[0046] (Example 3)

[0047] This embodiment is basically the same as embodiment 2, the difference is: see Picture 11 As shown, the bolt no longer includes a nut 34. In this embodiment, an internal threaded area 171 for fitting with the external threaded connection part of the bolt is provided in the limiting sliding hole of the sealing plate part; the rod of the bolt passes through the center of the core column Hole, the external thread connection part of the bolt is screwed to the internal thread area.

[0048] In this embodiment, a nut is saved and the structure is simplified.

Abstract

The invention discloses a wedge-shaped power line clamp, which comprises a base pipe, a core column, a bolt and a splint assembly; the base pipe includes a pressure tube part and a sealing plate part; the sealing plate part and the pressure tube part are relatively fixed; the sealing plate part is provided with a limit position Sliding holes and threading holes; crimping bosses are provided on the inner wall of the crimping tube; tapered crimping surfaces are provided on the outer peripheral wall of the stem; a center hole is provided at the center of the stem along the axial direction of the crimping tube; splint assembly Including the clamping plate; the inner wall of the clamping plate is provided with a guide slide for limiting the reciprocating movement of the core column along the axial direction of the pressure tube; Guide chute; each crimping boss is provided with a limit sliding column adapted to the guide chute; the clamping plate is set directly opposite to the corresponding crimping boss; the rotating bolt pushes each clamping plate along the diameter of the crimping tube. The base pipe is provided with a mounting screw hole; a temperature sensing device is fixed in the mounting screw hole. The structure of the invention is relatively compact and reasonable, and is easy to install.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to a wedge-shaped power line clamp. Background technique [0002] The bundled cables used for power transmission and distribution are generally two-core or four-core, and strain-resistant clamps are required when the bundled cables are fixed overhead on the utility pole. Chinese patent 03210522.3 discloses a strain clamp for four-core bundled cables. Two paired wedges are used to clamp the core of the cable and then penetrate into the wedge-shaped cavity of the clamp for tension. The wedge fit can make the cable over-tension. The tighter it is, the less likely it is to damage the core. However, using two paired wedges to clamp the wire may cause relative slippage, which affects the clamping reliability. This kind of strain clamp also needs to twist the parallel four-core bundled cables into a square shape during installation, and install it in the sam...
