AI Technical Summary

Problems solved by technology

Although the clamp is usually strong enough to hold the cable in place, this movement creates additional space within the clamp to allow the cable to move
This causes the components of the clamp, including the threaded portion of the now bent bolt, to cause damage to the outermost jacket of the cable

Embodiment Construction

[0044] See Figure 1 to Figure 3 The present invention provides a cable clamping device in the form of a cable clamp 10, which is used to clamp at least one cable. In the example, there are three cables, which are cables 12, 14, and 16, respectively. The cable clamp 10 includes a first cable clamping assembly 18 that engages the cables 12 and 14 in use. The cable clamp 10 further includes a second cable clamping assembly 20 that contacts the cable 12 and the other cable 16. in Figure 1 to 3 In the illustrated embodiment, the first and second cable clamping assemblies 18 and 20 are obtained by bending and welding steel plates into the shapes shown in these figures. The first and second cable clamping assemblies 18 and 20 are hingedly connected to each other by a pivot in the form of a hinge 22.

[0045] The cable clamp 10 further includes a clamping portion generally indicated at 24. The clamping portion 24 includes a first flange 26 mounted on the first cable clamping assembly...

Abstract

The invention discloses a cable clamping device for clamping three power cables, or a three-leaf cable clamp. The two halves of the clip hinge together and splice the three cables between them. There is also a clamping portion for pulling the two halves together, the clamping portion having a clamping member at the non-hinged end of each half. Both clamping members have holes therethrough, one of which has internal threads. There is also a bolt extending through the unthreaded hole and into the threaded hole. When the clamp is in use, the bolt has a non-threaded portion extending at least between the two clamping parts.

Description

Technical field [0001] The present invention relates to a cable clamping device, in particular to but not limited to a clamp for clamping three sheathed power cables used in three-phase power distribution. Background technique [0002] In the three-phase power transmission, if a three-phase short circuit occurs between any cables, the electromechanical force formed between the cables causes the cables to move suddenly and violently in the opposite direction. This is very dangerous for the voltage of distribution cables, which may cause personal injury and damage cables and peripheral equipment. [0003] Therefore, a cable clamp (also called a three-leaf clamp) is used to clamp the three cables together. Especially when the cables are installed on walls, floors or other surfaces, and in order to prevent a three-phase short circuit, the cables are clamped together with evenly spaced and firm clamps. An example of such a clamp in the prior art has a triangular frame, which can be di...
