Abstract
The invention discloses a shorting structure between multi-channel high-voltage cables. The shorting structure is characterized by comprising a shorting conductive member for achieving reliable shorting between the multi-channel high-voltage cables and an insulation member capable of enabling shorting positions between the multi-channel high-voltage cables to achieve high pressure resistance. The shorting conductive member is arranged in the insulation member. Metal contact parts of the shorting conductive member are arranged to be in pressing connection with the cables, so that the cables are in reliable connection with the metal contact parts. By arranging insulation lining sleeves and a rubber cable sealing body of the insulation member, compressive deformation of the rubber cable sealing body blocks contact between the shorting conductive member and outside air, the creep distance between the shorting conductive member and the outside is increased, and the high pressure resistance of the shorting structure is achieved. The shorting structure between the multi-channel high-voltage cables is simple, low in cost, capable of achieving safe and reliable shorting between the multi-channel high-voltage cables, small in occupied space, convenient to use, further suitable for shorting of multi-channel cables needing sealing, and wide in application.
