A light-weight high-temperature electrical connector with detachable contacts

Abstract

The invention provides a detachable lightweight high-temperature electrical connector comprising a base assembly, a screw sleeve assembly and a housing assembly. The base assembly, the screw sleeve assembly and the outer shell assembly are arranged from the inside to the outside in sequence; The base assembly comprises a lower base and an upper base, wherein a contact part and a stay spring ring are arranged in the upper base, one end of the upper base is buckled with the lower base, and the other end of the lower base is provided with a nut; The support spring coil is arranged at both ends ofthe contact piece; The peripheral ring of the support spring coil is a support barb structure, and the contact piece is fixed by the support barb; The screw sleeve assembly is installed from the tailend of the shell part and fixed by a retaining ring; The nut presses the base assembly into the housing joint. The invention can meet the requirements of high-temperature use, and the shell materialdensity is small, and the weight reduction purpose can be achieved, and the weight loss is about 30% compared with the existing high-temperature products with the same specification; The contact piececan realize the disassembly function and satisfy the reliability of the assembly between the parts.

Description

Technical field [0001] The invention relates to a high-temperature electrical connector with a detachable contact piece and a lightweight, belonging to the technical field of electrical connectors. Background technique [0002] The maximum working temperature of conventional electrical connectors is usually 200℃. Some connectors use glass sealing process to sinter the contacts and the shell into one body, which can be used at 500℃ for a long time, but the contacts of this type of connector cannot be removed. , Does not have maintainability, and due to the limitation of the sintering process, the product shell and contact parts can only be made of high-density constant expansion coefficient alloy materials, which are heavy, and their use in the aerospace and aviation fields is restricted. For example, the application number is The Chinese patent of 2012204500169 discloses a high temperature resistant sealed electrical connector with a detachable structure. Summary of the inventio...

[0002] The maximum working temperature of conventional electrical connectors is usually 200°C. Some connectors sinter the contacts and shells into one body through the glass sealing process, which can be used at a high temperature of 500°C for a long time, but the contacts of this type of connector cannot be disassembled , does not have maintainability, and due to the limitation of the sintering process, the shell and contact parts of the product can only be made of alloy materials with a relatively high density and a constant expansion coefficient, which is heavy and its use in the aerospace and aviation fields is restricted. For example, the application number is Chinese patent 2012204500169 discloses a detachable high temperature resistant sealed electrical connector
