Sealed electric connector with silicon-aluminum alloy shell and manufacturing method of sealed electric connector

Abstract

The invention provides a sealed electric connector with a silicon-aluminum alloy shell and a manufacturing method of the sealed electric connector. The electric connector comprises the silicon-aluminum alloy shell, low-temperature sealing glass and a low-carbon steel contact piece. The manufacturing method comprises the following steps: preparing a glass insulator; pretreating the shell; carrying out pre-oxidation treatment on a contact piece; spraying a high-temperature protective coating on a sintering mold; assembling all the parts, and putting the parts into a sintering furnace to be sintered, fused and sealed; carrying out descaling and cleaning; coating high-temperature glue on the exposed surface of the glass insulator and performing curing treatment; and performing gold plating to obtain the electric connector. According to the invention, silicon-aluminum alloy sealing sintering is realized, the problem of poor material matching performance in the welding process of a traditional kovar alloy glass sintering sealing electric connector and a T / R assembly shell is improved, the sintering binding force is also improved, the problem of sealing performance failure in the use process of the sealing electric connector is solved, and the use reliability of the electric connector is improved.

Description

technical field [0001] The invention belongs to the field of electrical connectors, and in particular relates to a sealed electrical connector with a silicon-aluminum alloy shell and a manufacturing method thereof. Background technique [0002] At present, sealed electrical connectors are widely used on T / R components for internal and external signal transmission. The electrical connectors are usually welded on the T / R housing to ensure the overall sealing of the components while transmitting signals. The sealed electrical connector used on T / R components is mainly made of Kovar alloy material (4J29) and DM-305, DM-308 electronic packaging glass by high-temperature sintering, in order to ensure that the component shell and the electrical connector are welded and matched The T / R component housing material is usually 4J29. However, with the development of electronic packaging technology in the direction of miniaturization, light weight, and high-density assembly, at present, ...
