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...
