Electrical Plug Connector for Flexible and Stationary Wiring Applications

Connectors (Plugs) are designed for plug and cable connections of flexible cable and fixed power wiring with mobile and stationary sources and receivers of electrical energy in DC and AC circuits with frequency up to 50 Hz at voltage up to 400V (amplitude value), in normal climatic conditions, as well as in the cold northern climate. The connectors are designed for connection and disconnection without connected load of flexible cables with copper or its alloy cores. According to the method of cable fastening the connectors are collapsible, with terminals for earthing. A mechanical locking device is provided, which holds the plug or portable socket in the mating position and prevents its accidental falling out. Contacts and bodies of connectors are made of alloys with high mechanical strength.
