Embodiment Construction

[0013] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0014] Embodiment: Select a section of seven-strand aluminum core insulated wire 11, the aluminum core is twisted into strands, the pitch is about 150mm, the insulation layer 12 of about 30mm is stripped off at both ends, and a section of heat-shrinkable insulating sleeve of about 50mm is placed on each end 13, then bend the insulated wire 11 into a circle, insert the end of it into the conductive section 14 made of copper pipe (crimping pipe), press the two into one with a special wire connection fixture, and make the surface tin-plated (to avoid The two ends of the standard crimping tube with copper oxide on the surface, etc.) are embedded in the aluminum core strands 15 to form a polygonal compression contact portion 16 to maintain good contact. Then move the heat-shrinkable insulating sleeve 13 bet...

Abstract

This invention relates to a cable drainage ring matched with an insulation puncture wiring clip, mainly altering the said conductor to several conductive strands, the said conductor and the insulation layer constitute a sectional cable exposing its both ends connecting the section, insulation bushing is set between the insulation end of the wire and the two ends of the conducting section, especially suitable for connection with insulation puncture clips with electricity for temporary earth protection.

Description

technical field [0001] The invention relates to an electrical connection appliance, in particular to a cable-type drainage ring used in conjunction with an insulation piercing clamp and the like. Background technique [0002] With the rapid development of my country's economy, the construction and transformation of urban and rural power grids for power transmission in my country has achieved rapid development. Extensive use of insulated cables has become one of the main methods for the construction and transformation of transmission cables. Therefore, the insulation piercing clamp will be used as an important power distribution connection fitting, and it will attract more and more attention. For example, someone has applied for "a kind of puncture wire clip" (patent application number 01249680.4), which includes an upper shell and a lower shell with screw holes. In the groove, the upper shell and the lower shell are parallel to the two sides of the thorn block groove and h...
