Problems solved by technology

This internal stress will be released through post-process processing or natural failure, destroying the post-sealability of the product
At the same time, these two processing methods also occupy precision machine tools, have low efficiency, high cost, and are not commercially competitive.

Embodiment Construction

[0037] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0038] The fusion sealing process of the micro-pitch glass hermetic connector 1 includes a molding tool 2 for clamping the micro-pitch glass hermetic connector 1 during fusion sealing. Such as Figure 1 to Figure 2 As shown, the micro-pitch glass-sealed connector 1 includes a metal shell 11 with a stepped shape and a stepped groove 111 at its lower end, and a roughly trapezoidal glass body 12 is sintered in the hole at the ...

Abstract

The invention discloses a micro-spacing glass sealing connector fusion sealing process. The process comprises a formation tool for clamping a micro-spacing glass sealing connector during fusion sealing. During the fusion sealing, the technical process includes sintering a vitreous body, assembling the micro-spacing glass sealing connector and the formation tool, performing fusion packaging on the micro-spacing glass sealing connector, flattening the end portions, which are disposed outside a metal housing, of a first contact member and a second contact member, and performing secondary sintering on the micro-spacing glass sealing connector. According to the scheme, the formation tool designed according to the concrete structure of the micro-spacing glass sealing connector can realize accurate positioning of the micro-spacing glass sealing connector, guarantees the sealing performance of the connector during the fusion packaging, and at the same time, reduces formation of harmful internal stress. After a flattening process, potential cracks during flattening can be fused and internal stress of the vitreous body can be fully eliminated through a secondary sintering process (the fusion packaging is primary sintering), and the influence on airtightness is thoroughly eliminated.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a melting and sealing process for a micro-pitch glass hermetic connector. Background technique [0002] The original process flow mode: assembly of graphite mold, metal parts and glass blank parts → high temperature glass sealing → electro-etching processing of bonding surfaces (or grinding processing of bonding surfaces) → electroplating process, the airtight performance of products produced by the above methods is difficult to guarantee . It is mainly manifested in that after the glass is sealed, in order to ensure the smoothness of the gold wire bonding of the product and the consistency of bonding, the bonding surface at the end of the socket is electroeroded or ground. If electrolytic processing is used, the electric spark and electric heat are transmitted to the glass body through the end of the socket to form internal stress due to thermal expansion difference. If the bonding su...
