Quick electrical-connecting structure for high-voltage high-frequency pulse environment

A quick electrical-connecting structure for a high-voltage high-frequency pulse environment, comprising a plug, a socket, and a cable, wherein

• the cable is connected to the socket through the plug;
• and
• the plug and the socket internally enclose an annular cavity surrounding the cable;
• and a protective fluid is filled in the annular cavity,
• wherein a side of the socket adjacent to the plug is provided with an accommodation groove for accommodating a head of the cable;
• an inner diameter of the accommodation groove is greater than a diameter of the cable;
• and after the cable is inserted into the accommodation groove, the cable is not in contact with an inner sidewall of the accommodation groove, and
• wherein a first annular cavity is formed in the socket;
• the first annular cavity is sleeved outside the accommodation groove;
• the socket is provided with an annular axial protrusion between the first annular cavity and the accommodation groove;
• and the annular axial protrusion is sleeve-shaped, wherein the accommodation groove is formed at an inner side of the annular axial protrusion, and the first annular cavity is enclosed by an outer side of the annular axial protrusion and the socket.

A quick electrical-connecting structure for a high-voltage high-frequency pulse environment, comprising a plug, a socket, a cable and a locking device, wherein

• the cable is connected to the socket through the plug;
• the plug and the socket internally enclose an annular cavity surrounding the cable, and a protective fluid is filled in the annular cavity;
• wherein the plug comprises a plug body;
• a through hole is formed in the plug body;
• the cable is inserted into the through hole from a second end of the plug body;
• the head of the cable is stretched out of the through hole from a first end of the plug body;
• and after the first end of the plug body is connected to the socket in a sealing manner, the head of the cable is stretched into the accommodation groove;
• and
• the locking device is for sealing and fixedly connecting the cable and the plug body, wherein the locking device comprises a cable locker and a locking sleeve;
• a first end of the cable locker props against the second end of the plug body, and a second end of the cable locker is provided with a plurality of elastic sheets arranged circumferentially at intervals;
• a first end of the locking sleeve is in screw-thread fit with the plug body, and a second end of the locking sleeve is provided with a wedge-shaped surface;
• the cable passes through the cable locker and the locking sleeve;
• and when the locking sleeve is screwed, the plurality of elastic sheets are shrunk radially through the wedge-shaped surface to clasp the cable.
