Mine flameproof high-voltage cable connector

Abstract

The invention relates to a mine flameproof high-voltage cable connector. The connector consists of a chassis, a fitting nut, a novel conducting rod, a wire holder, an outer shell, an iron bracket, an inner grounding conducting block, bolts, a tail holder, a check ring, a sealing ring, a pressure plate, a positioning pin and an outer grounding bolt, wherein one end of the outer shell is provided with the chassis; the positioning pin is arranged on one side of one end of the outer shell connected with the chassis; the other end of the outer shell is connected with the tail holder in a form of screwing the bolt; the check ring is arranged in the tail holder; the sealing ring is arranged outside the check ring; the outer end of the tail holder is in bolt connection with the pressure plate; the novel conducting rod is arranged in the outer shell; an encapsulation-free type insulator is arranged outside the novel conducting rod; the wire holder is arranged at the inner end of the novel conducting rod; and the outer end of the wire holder is connected with one end of the iron bracket, and the other end of the iron bracket is extended to be connected with the tail holder. The mine flameproof high-voltage cable connector has the advantages of simple overall structure, convenient disassembly, assembly, maintenance and use, light overall weight, good working stability and high reliability.

Description

Technical field: [0001] The invention relates to a connecting device for electric cable appliances, in particular to a mine flameproof high-voltage cable connector. Background technique: [0002] The mine cable connectors currently available in the market are composed of symmetrical components assembled in the shell, left and right symmetrical insert rods, sockets, insulators, seals, inner ground connection bolts and outer ground connection bolts. Shell, wiring cavity, crimping cavity and pressure plate. In the hole on the side of the lead-in cable, there are small platform steps with the same length as the hole, so that the connecting part of the main core of the cable and the socket cannot be wrapped for insulation, which limits the improvement of electrical properties, and its power frequency and impact withstand voltage can only meet 500Kv The basic insulation level of the following power transmission and transformation equipment is medium, and the overall weight is rel...

AI Technical Summary

Problems solved by technology

In the hole on the side where the cable is introduced, there is a small platform step with the same length as the hole, so that the connecting part of the main core of the cable and the socket cannot be wrapped to increase insulation, which limits the improvement of electrical properties, and its power frequency and impact withstand voltage can only meet 500Kv The basic insulation level of the following power transmission and transformation equipment is medium, and the overall weight is relatively heavy

In the specific use process, the insertion rod and the socket need to be plugged and pulled out frequently, which are easy to be damaged, and the maintenance and replacement are not convenient enough
