Detachable high-voltage connection structure and high-voltage connector

Abstract

The invention discloses a detachable high-voltage connection structure, comprising a jack component and a contact pin component, wherein the contact pin component at least comprises a contact pin shell, a contact pin and a sealing sleeve; a groove is formed in the front end face of the contact pin shell; the middle part of the contact pin shell is provided with a mounting trough matched with a contact pin in shape; the contact pin is mounted in the mounting trough, a first wiring duct is formed in the rear part of the contact pin shell; a first high-voltage wire is connected with the contact pin via the first wiring duct; the jack component at least comprises a jack shell and a jack member; a second wiring duct is formed in the front part of the jack shell; a second high-voltage wire is connected with the jack member via the second wiring duct; a first tail sleeve is mounted on in the side wall of the first wiring duct in a sleeved manner; a second tail sleeve is mounted in the side wall of the second wiring duct in a sleeved manner. The first tail sleeve greatly improves the voltage-withstanding effect of the rear part of the contact pin component, can be freely inserted and pulled out and is convenient to replace; the second tail sleeve greatly improves the voltage-withstanding effect of the front part of the jack component, can be freely inserted and pulled out and is convenient to replace.

Description

technical field [0001] The invention relates to a detachable high-voltage connection structure; the invention also relates to a high-voltage connector. Background technique [0002] At present, the high-voltage connection structure of high-voltage electrical connectors usually includes a jack assembly and a pin assembly; the pin assembly includes at least a pin housing, a pin and a sealing sleeve, and the front end of the pin housing has a groove, and the pin There is a mounting groove matching the shape of the pin in the middle of the housing. The pin is installed in the mounting groove. The rear part of the pin is the first connection end. The front end of the pin passes through the sealing sleeve and extends into the groove. The groove is set with Elastic insulating sealing sleeve, the front end of the sealing sleeve is open and has an everted flange matching the groove, the rear end of the sealing sleeve is closed and fitted on the pin, the length of the pin is such that...

Problems solved by technology

[0003] However, it is necessary to ensure the sealing performance between the various parts of this kind of socket assembly or pin assembly, so the matching size and accuracy requirements must be ensured during processing. Because the cavity needs to be slotted, slotting is more difficult in the design of the connector. In addition, the above-mentioned structure often uses potting treatment to achieve high voltage resistance at the tail. Once the product after potting treatment is damaged, it cannot be repaired.

[0004] The high-voltage connector includes a socket and a plug. The socket is equipped with several jack components of the above structure, and the plug is built with the pin component of the above structure. The plug and the socket are mated correspondingly, which can conveniently realize the connection between high-voltage equipment or internal modules of the equipment. High-voltage connection, but it is integrally molded during processing, which is difficult to process, high in cost, and poor in interchangeability; and because of the characteristics of transmitting high-voltage signals, after a high-voltage wire or several high-voltage wires break down and fail, Since the discharge channel after breakdown cannot be repaired, the entire set of connectors must be replaced, which is time-consuming, laborious, and costly
