Problems solved by technology

However, in the actual use process, due to the deviation between the size of the clamp itself and the outer diameter of the wire, when the outer diameter of the wire conductor is too small, there is a certain gap between the installation of the clamp and the wire, resulting in poor contact
When the outer diameter of the wire conductor is too large, the installation of the clamp and the wire cannot be flattened and self-locking cannot be realized
Furthermore, there are more than 40 models and specifications of C-type clamps, resulting in difficulties in emergency repairs and a large amount of spare parts.

Abstract

The invention discloses a cylindrical electric power connection lead clamp which comprises a first clamp body, a second clamp body, a third clamp body, rivets and a locking wedge block, wherein the first clamp body, the second clamp body and the third clamp body are each of a sector-ring-shaped structure and are riveted through the rivets; the electric wire clamping groove in one side wall of the first clamp body is matched with the main wire clamping groove of the third clamp body to achieve locking of an electric power main wire, and the electric wire clamping groove in the other side wall of the first clamp body is matched with the branch wire clamping groove of the second clamp body to achieve locking of an electric power branch wire. The locking wedge block is installed in the wedge block clamping groove and the wedge block locking clamping groove between the second clamp body and the third clamp body, and locking of the whole cylindrical electric power connection lead wire clamp is achieved. The cylindrical electric power lead connecting clamp is good in current-carrying capacity, capable of being universally suitable for clamping and fixing main lines and branch lines with different line diameters, good in universality, convenient to recover insulation, convenient for live-line lead disconnecting and connecting operation, stable, reliable and convenient to operate, and the dismounting and mounting convenience and the overall maintenance efficiency of the lead connecting clamp are effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric appliances, in particular to a cylindrical electric lead clamp. Background technique [0002] With the development of modern society, users have higher and higher requirements for power supply reliability. The distribution network is responsible for the task of supplying and distributing electric energy to various users locally or step by step, and is the most direct and critical link to ensure the quality of power supply. In order to meet the needs of mechanical and electrical performance, various types of electrical connectors continue to develop, and the terminal clip is one of the widely used ones. As a popular technology for the drainage of distribution network lines, the lead wire clip has achieved a certain degree of success in practical applications. However, in recent years, under the dual effects of urban development and economic construction, both domestic and engineering electricity ...
