Description

Micro pitch hermetic connector

technical field

The utility model relates to an electric connector, in particular to a micro-distance air-tight connector.

Background technique

Micro-pitch hermetic connectors are mainly used for circuit connection of various military electronic equipment, especially suitable for occasions where the installation space is extremely small and light weight is required. Due to the different use environments, it is especially required that the micro-pitch socket has a high airtight characteristic.

The socket part of the existing macro-pitch hermetic connector adopts a metal shell, and the plastic molding process, because the plastic is easy to age, has poor corrosion resistance, short service life, and poor sealing performance, it is easy to reduce the sealing performance of the connector , resulting in circuit failure.

In view of this, it is necessary to provide a reliable sealing method for the macro-pitch connector to ensure that it has good sealing performance, is resistant to harsh environments, and can well meet various system requirements.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned defects and provide a macro-pitch air-tight connector with long service life and good sealing performance which can be used in relatively severe environments.

In order to solve the above problems, the technical solution adopted in the utility model is:

A micro-distance type hermetic connector, including two parts: a socket and a plug, characterized in that: the socket is fixedly installed on the installation panel of the system cavity, including a micro-distance type socket shell for connecting electrical equipment, several devices The glass insulators in the micro-pitch socket shell and the socket contacts corresponding to the glass insulators; the socket shell and the socket contacts are fixed by the glass insulator sintering and welding process, which can realize the product Performance, generally achievable leakage rate is less than 1.01×10 ^-3 Pa.cm ³ /s; the plug is a free end, including the plug base, pin contact assembly, plug shell and potting sealant; the plug base There is a twisted wire pin in the cavity of the butt end hole; the twisted wire pin and the wire are crimped and connected with a pin sleeve; after the plug part is inserted, it is fastened to the installation with a fastening screw On the layout, the locking requirements are met.

Due to the adoption of the above technical solution, compared with the prior art, the utility model has the following advantages: good air tightness, excellent compression resistance, and can be applied to relatively harsh working environments.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
