Circular Flange Marked Multi‑Pin Hermetic Connector Base

This hermetic connector base uses a circular flange as its mounting interface, organizes its connections in a multi-pin format, and carries a marking process. The circular flange provides a circumferentially uniform mounting face, which suits installation on round mating surfaces. The multi-pin structure means the base contains several independent pin channels gathered into one base body. Marking is a surface process applied to the base, forming identification on the housing or flange face so parts can be distinguished during assembly or use. Combined, these three features give the base both the locating ability of a flange mount and multi-channel connectivity, while retaining identification information on the surface.

Combining marking with a multi-pin structure places certain demands on process sequencing. The technical team has long been engaged in metal-glass sealing research and holds more than twenty independent intellectual property rights. For a base with surface identification, the marking step usually needs to be coordinated with sintering and plating so later processes do not affect marking clarity. The company holds more than fifty national patents and has developed hundreds of product variants used in hybrid integrated circuits, relays, sealed connectors, and pressure sensors.
