Snap spring fixing type rectangular electric connector

Abstract

The invention relates to a snap spring fixing type rectangular electric connector. The connector comprises a housing and an insulating assembly, wherein the inner end face of the insulating assembly is attached to a heavy platform in the housing correspondingly, more than one snap spring slots are arranged on one or more side walls of the insulating assembly, more than one positioning bosses are arranged on one or more inner walls of the housing, snap springs which are pressed in the snap slots tightly by the housing inner walls are arranged in snap spring slots, and the snap springs abut against the sides of the positioning bosses, which face to the inside of the housing. The snap spring slots and through slots which are communicated are arranged on the insulating assembly, positioning bosses in the housing are inserted in through slots correspondingly, snap springs in snap spring slots press tightly, and the insulating assembly and the housing are clamped fixedly. The connector is simple in structure, firm, free from clearance, suitable to harsh environment, not easy to damage, stable in use and long in service life.

Description

technical field [0001] The invention relates to a rectangular electrical connector, in particular to a rectangular electrical connector which utilizes a clip spring to fix a shell and an insulating component. Background technique [0002] With the progress of the times and the development of society, rectangular electrical connectors are widely used in aviation, aerospace, communication and other fields. The insulator components of traditional rectangular connectors are mainly fixed in the shell by epoxy glue. When the rectangular connector is used in harsh environments, Epoxy glue will soften in high temperature environment, easy to absorb moisture in humid environment, and easy to crack in strong vibration environment. Rectangular electrical connectors that rely on epoxy glue to fix insulator components cannot meet the requirements of harsh environments, and there are potential safety hazards in use.

[0002] With the progress of the times and the development of society, rectangular electrical connectors are widely used in aviation, aerospace, communication and other fields. The insulator components of traditional rectangular connectors are mainly fixed in the shell by epoxy glue. When the rectangular connector is used in harsh environments, Epoxy glue will soften in high temperature environment, easy to absorb moisture in humid environment, and easy to crack in strong vibration environment. Rectangular electrical connectors that rely on epoxy glue to fix insulator components cannot meet the requirements of harsh environments, and there are potential safety hazards in use

[0003] Existing rectangular connectors that use a mechanical structure to fix the insulator assembly can avoid the above-mentioned defects of epoxy glue bonding. For example, the rectangular connector disclosed in Patent No. 201220114017.6 uses an insulator to install the front end of the reed with a limit surface facing forward. The corresponding two corners of the rectangular inner cavity are provided with guiding slides for the bending structure to be slid from front to back. The installation structure limit step of the insulator installation reed to move forward limit and the installation structure positioning groove that cooperates with the positioning of the absolute rear positioning reed to make the insulator installation reed move backward limit, the insulator part is provided with the front positioning spring The insulator is equipped with a reed limit slot for the positioning of the insulator so that the insulator can move backward. The structure of the reed is complex, it is inconvenient to manufacture and assemble, and there is a space for installing the reed between the rectangular housing and the insulator, the gap is large, the overall connection structure of the rectangular electrical connector is unstable, and it is used in a long-term multiple plugging or vibration environment , the reed is easy to loose, causing the reed to deviate, making the rectangular connector loose, and the performance is unstable
