Electric connector resisting nuclear electromagnetic pulses

Abstract

The invention relates to an electric connector resisting nuclear electromagnetic pulses, comprising a socket and a plug. The socket is formed by sequentially connecting a socket outer shell, a plastic closing ring, a lower base, a grommet, a bracing spring ring, a contact pin, a top base, an interface sealing gasket and a sealing ring; the plug is formed by sequentially connecting a threaded sleeve, an elastic gasket, a static ratchet wheel, a movable ratchet wheel, an end outer shell, a plastic closing ring, a lower base, a jack, a grommet, a bracing spring ring and an end top base; and the socket outer shell and the end outer shell of the electric connector are made of permeable magnetic material while conductive material is coated on the surface, a shielding spring leaf is axially arranged on the excircle of the end outer shell, and conductive rubber gaskets are arranged on abutting end surfaces so as to form a full-closed shield. The electric connector has excellent conductivity, effectively shields electromagnetic interference caused by an external electrical field and magnetic variation and enhances the capability of resisting strong electromagnetic pulses caused by nuclear bursts.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors. Background technique [0002] With the development of electronic technology, semiconductor devices and integrated circuits are more and more commonly used in various electronic equipment. The nuclear electromagnetic pulse has a huge destructive effect on these electronic equipment. The principle of action is that the electromagnetic pulse generated by the nuclear explosion can enter the electronic equipment through antennas, cable connections, metal pipes, etc., and induce currents, causing serious damage to electronic equipment. In addition, the additional signal introduced by the nuclear electromagnetic pulse will also change the working state of the device, resulting in dysfunction of electronic equipment and sending out wrong signals. Although the nuclear electromagnetic pulse is short-lived, its functional damage to electronic equipment, circuits and electronic components is p...

AI Technical Summary

Problems solved by technology

[0003] The way to prevent nuclear electromagnetic pulse is to shield electronic equipment with metal materials with high conductivity and high magnetic permeability, but the existing types of electrical connectors are usually made of aluminum alloy or copper alloy materials, which do not have the ability to resist nuclear electromagnetic pulse
