Circular high-voltage connector in threaded connection

Abstract

A circular high-voltage connector in threaded connection comprises a plug and a socket. The plug comprises a plug shell, a connecting sleeve, a circular plug mounting tube, a plug retaining board and a jack contact part which are horizontally arranged and coaxial. The socket comprises a vertical flange plate, a circular connecting barrel, a socket shell and a plugging pin contact part, wherein the circular connecting barrel, the socket shell and the plugging pin contact part are horizontally arranged and coaxial. The plug mounting tube is made of silicon rubber, and the socket shell is made of ceramics. The length of a circular shaft is larger than the depth of an inner hole of a hollow cylinder, so that the front end of the circular shaft sufficiently closely contacts with the rear end of the inner hole of the hollow cylinder. The diameter of a fourth boss is larger than the inner diameter of a first hole, the fourth boss closely contacts with the front end face of the plug mounting tube, the front of the plug mounting tube is plugged into a first jack of the socket shell, the circular shaft is internally and externally plugged with the hollow cylinder, the connecting sleeve is in screwed connection with the front of the connecting barrel, and the front end of the socket shell closely contacts with the front end of a second boss, so that the plug is connected with the socket. The circular high-voltage connector is resistant to high voltage.

Description

technical field [0001] The invention relates to a threaded circular high-voltage connector used in high-voltage electronic equipment. Background technique [0002] At present, high-voltage connectors (especially 60kV d.c. high-voltage connectors) are mainly used for connection and transmission of high-voltage power supplies in high-voltage electronic equipment. [0003] The high-voltage resistance performance index is the key point and difficulty of high-voltage connectors. Since the working voltage of the high-voltage connector is very high (60kV d.c.), considering the pulse at the moment of on-off, in order to ensure the reliability of the work, a design margin of 1.16 times is generally used, that is, the withstand voltage of the high-voltage connector must reach 70kV d.c. Meet the design requirements. Under the conditions of such a high withstand voltage index, the performance requirements for insulating materials are very strict. Insulating materials must not only hav...
