ELECTRIC-CONTACT CONNECTOR Russian patent published in 2005 - IPC

FIELD: electrical engineering; latching connectors for electrical equipment.

SUBSTANCE: proposed electric-contact connector has socket incorporating shroud, insulator, shock absorber, and latching mechanism; and plug with insulator and ring embedded therein. Shroud is threaded to receive cylindrical-surface bushing provided with clamp and outside thread. Cylindrical surface of bushing carries ring with clamp engageable with bushing clamp and with at least two shaped slots. Vertical displacement of ring is restricted by nut with minimal clearance affording its free rotation; slots have tapered vertical part and horizontal part with shoulder and are engageable with projections of ring embedded in plug insulator. This connector can be used as connector/disconnector of power circuits. It can be also used for coupling high-voltage power circuits of adjacent cars of high-speed electric trains.

EFFECT: simplified latching mechanism, enhanced speed and reliability, reduced size, mass, and cost.
