Small sealed high-voltage resistant connector and split insulator used for connector

Abstract

The invention discloses a small sealed high-voltage resistant connector. The inside of a shell of the connector is provided with a contact part along the axial direction; a front insulator and a rear insulator are arranged between the contact part and the shell; an O-ring sleeved on an outer circle of the contact part is clamped between the front insulator and the rear insulator; and an inner ring and an outer ring of the O-ring is axially extruded by the front insulator and the rear insulator to form the sealing between the contact part and the inner wall of the shell. The connector simplifies the process of the prior complicated manufacturing technology, greatly improves the rate of finished products, and greatly reduces the manufacturing cost for sockets on the premise of satisfying various performances; and the O-ring is firmly clamped and then partitions the air gap between the shell of the connector and the contact part to form the sealing, which increases the voltage withstanding index of the connector and can fully satisfy the application on special occasions. The invention also provides a split insulator used for the small sealed high-voltage resistant connector.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a small high-voltage connector with good airtightness. Background technique [0002] At present, with the rapid development of science and technology, higher and higher requirements are put forward for connectors used in electronic technology. In some special occasions, it is necessary to use an electrical connector with a single contact piece with a small outer diameter, and its mating surface is only 6.5mm. This kind of connector not only requires good airtight performance, but also has a leakage rate of 1.0 x10 -10 Pa.m 3 / s, and after the connector is mated, it must also have high-voltage resistance performance, and its withstand voltage is above 5000V. [0003] In the existing technology, there are two manufacturing methods for the connector: [0004] 1. It is completed by ceramic sintering, using ceramics as an insulator, and connecting the contact parts o...

AI Technical Summary

Problems solved by technology

[0004] 1. It is completed by ceramic sintering, using ceramics as an insulator, and connecting the contact parts of the connector with the shell as a whole, but its disadvantages are: the technical requirements of ceramic sintering are very high, which makes the defective rate of the product too high, so the product the cost is too high;

[0005] 2. It is completed by glass sintering, and the contact parts of the connector and the shell are sintered into one body. The disadvantages are: the insulating layer of the connector is thin, and the glass sintering is difficult, so the requirements for the mold are very high, and the pressure resistance of the glass The index is unstable, and the withstand voltage index of the manufactured connector is unqualified, so it is not suitable for use in high voltage applications

[0006] Moreover, no matter which method is used to make it, the shell and the contact piece are sintered into one, so that the connector cannot be repaired when it is damaged and can only be discarded, thereby increasing the use cost of the connector.
