Problems solved by technology

A small number of multi-core high-voltage resistant electrical connectors cannot be widely used in aerospace, aviation and other fields due to their complex internal structures, and cannot realize high-voltage signal transmission in low-pressure environments
[0003] In recent years, some high-voltage multi-core connectors have appeared, with a withstand voltage of 1000VDC to 10000VDC. Although they can be used in aerospace, aviation and other technical fields, there are still problems such as unstable withstand voltage and defective environmental adaptation, such as:

Abstract

A high voltage resisting electric connector is provided with a tail high voltage resisting device which comprises a wire seal (15) and a cover board (7). The wire seal (15) and the cover board (7) isolate adjacent wires (9) in a sealing mode and / or isolate a wire (9) from a connector shell in a sealing mode jointly. The cover board (7) is arranged behind the tail of the wire seal (15) and fixed to the connector shell. The cover board (7) is made of materials harder than materials of which the wire seal (15) is made. The wire (9) penetrates through an inner hole of the wire seal (15) and an inner hole of the cover board (7) at the same time. The wire (9) is in interference fit or small clearance fit with the inner hole of the cover board (7). The high voltage resisting electric connector has the stability of high voltage resistance and good space adaptability.

Description

technical field [0001] The invention belongs to the technical field of high-voltage resistant electrical connectors, in particular to a sealed type high-voltage resistant electrical connector, which has a high resistance voltage characteristics. Background technique [0002] High voltage electrical connectors are widely used in aerospace, aviation, nuclear energy and other fields. Common high-voltage resistant connectors are generally single-core products. A small number of multi-core high-voltage resistant electrical connectors cannot be widely used in aerospace, aviation and other fields due to their complex internal structures, and cannot realize high-voltage signal transmission in low-pressure environments. [0003] In recent years, some high-voltage multi-core connectors have appeared, with a withstand voltage of 1000VDC to 10000VDC. Although they can be used in aerospace, aviation and other technical fields, there are still problems such as unstable withstand voltage...
