Center torsion type separation break-away electric connector

Abstract

The invention discloses a center torsion type separation break-away electric connector. A single central pulling rod separation mode cannot satisfy the diversified demands of spacecrafts on electric connectors. Contact pins are inserted in an insulator of a plug and a first insulator layer of a socket; jacks are embedded in a second insulator layer; a second spring is mounted between a socket shell and the second insulator layer; a plug cable cover is fixed with a torsion sleeve and a plug shell; a torsion rod sheath is sleeved on a torsion central rod, an inner embedded groove embedded with an outer embedded block of the torsion central rod is formed in the torsion rod sheath; a first spring is arranged between the torsion sleeve and the torsion rod sheath; the two ends of a volute spiral spring are fixed on the inner walls of the torsion central rod and the plug cable cover respectively; a handle passes through a groove of the plug cable cover and the torsion central rod; a locking sleeve passes through the second insulator layer and the first insulator layer, and the tail part of the locking sleeve is connected with a tightening nut. The center torsion type separation break-away electric connector expands the application scope of the separation break-away electric connectors; and the torsion unlocking mode avoids influences of axial impact and the like on the locking effect.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a central twisting, separating, and falling-off electrical connector that realizes the locking and separating of the electrical connector by twisting. Background technique [0002] The traditional locking methods of electrical connectors include screw locking, buckle quick locking, insert quick locking, thread locking, bayonet quick locking, pin-type quick locking, etc. Although these locking methods can achieve a good locking effect, they cannot be separated quickly. The separation and separation electrical connector is a special electrical connector, which is often used for the electrical connection and separation between the aircraft and the ground or between two parts of the aircraft, especially for the separation of the rocket from the ground, the separation between rocket stages and the separation of rocket ships. Commonly used separation methods include rod separation...
