A fast push-pull locking explosion-proof usb circular connector

Abstract

The invention discloses a rapid push-pull locking type anti-explosion USB (Universal Serial Bus) circular connector. The rapid push-pull locking type anti-explosion USB circular connector comprises a plug and a socket, wherein a metal end cover component is arranged at a front end of a nut fastening shell component in a threaded way; a four-core pin-including insulator component is fixedly arranged in the nut fastening shell component through a clamp spring A; a four-core hole-including insulator component is fixedly arranged in a spline shell through a clamp spring B; a hexagonal nut sleeves the spline shell; a tail screw cap is in threaded connection with a back end of the spline shell; a connection screw cap is arranged on the spline shell through the clamp spring B; and a stainless steel screw is in threaded connection with the connection screw cap. The rapid push-pull locking type anti-explosion USB circular connector has a push-pull locking structure, is easy, convenient and reliable to operate, and saves space. An IP67 protection level is reached, and anti-explosion performance is realized. Double unblocking prohibition and double unlocking permission are adopted, so that poor contact and error operations are effectively avoided. An electric connector technology and a USB serial parallel communication technology are combined perfectly, so that the circular connector is particularly suitable for complex and severe environments of petroleum, coal mines and the like.

Description

technical field [0001] The invention relates to the technical field of electrical connectors and serial bus communication, in particular to a fast push-pull locking type explosion-proof USB circular connector structure. Background technique [0002] A circular connector is a type of connector whose basic structure is cylindrical and has a circular mating surface. In the interconnection classification, it belongs to category 5. It is used for interconnection between devices. The pins and socket leads of circular connectors are welded or crimped, and the plugs and sockets can be equipped with pins or holes. It has the characteristics of reliable structure, small size, light weight, quick connection, quick separation, vibration and shock resistance, etc., and is widely used in the electrical connection between instruments and electronic equipment. With the miniaturization and convenient operation of electronic equipment, circular connectors are required to have a quick plug-...

AI Technical Summary

Problems solved by technology

The disadvantages of adopting this fast plug-in and pull-out locking mechanism are: firstly, it is difficult to process and detect the spiral groove on the socket shell; The friction between them is relatively large, and the screw sleeve is difficult to screw together. In the case of limited assembly space, it is very difficult to connect the plug and the socket.

However, in coal mines, petroleum and other fields, it cannot be widely used because it cannot meet the harsh and complex industrial environment.
