Abstract

The invention discloses a high-temperature sealed connector and a manufacturing method thereof. The connector comprises a housing provided with a through hole, a contact part is arranged in the through hole of the housing and comprises an insertion hole contact member and a pin inserted into the insertion hole contact member, two ends of the insertion hole contact member are provided with split slot insertion holes, the pin is inserted into one end of the insertion hole contact member, the other end of the insertion hole contact member is level with an end face of the housing, the pin passes through a ring body made of a ceramic medium, the ring body is inserted into a tail stepped hole of the housing, the pin, the ring body and the housing are welded by a ceramic-metal brazing technique to form a sealed body, a stepped hole mouth part of the housing fixes a fixed ring into the stepped hole by a laser welding process, the fixed ring is level with an end face of the housing, and the outer circle surface of the fixed ring cooperates with the inner hole surface of the housing. The connector of the invention satisfies the requirement of use in a high-temperature environment of 600 DEGC and has sealing performance.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a high-temperature sealed connector and a manufacturing method thereof. Background technique [0002] Electrical connectors used in aerospace vehicles are usually required to have airtight performance, and in some key devices such as engines, electrical connectors are also required to meet high temperature requirements. The insulation support material of conventional electrical connectors is made of engineering plastics, such as polytetrafluoroethylene, polyphenylene sulfide, etc. The service temperature of plastics does not exceed 300 ° C, and cannot be used in higher temperature environments. [0003] Sealed connectors generally adopt glass-metal sealing technology, using the glass body as the insulating medium, and performing high-temperature sealing with metals such as Kovar alloy or stainless steel, but the glass body begins to undergo phase transformation at around 450°C and gradu...
