Power supply socket system

Abstract

The invention discloses a power supply socket system. Main parts comprise an inserting sleeve, an outer ring and an assistant holding force driving system; the inserting sleeve is divided into two parts, the front part of the inserting sleeve has a thick end and a thin root to form petals slightly opening outwards, and the back part of the inserting sleeve is a circular ring; and under an initial state, the outer ring is sleeved on the circular ring. The outer ring is subjected to a forward pushing force of the driving system, the outer ring slides to the area of the petals from the circular ring, and an inward axis holding force is provided for the petals, so that an inserting pin inserted in the inserting sleeve is in tight contact with the inserting sleeve, the contact resistance is reduced, and reliable power supply is guaranteed. When the service stage is retreated, the outer ring is subjected to a backward pulling force of the driving system, the outer ring is retreated to the circular ring area of the back part of the inserting sleeve, and the outer ring relieves a constraining force for the petals, so that the petals are recovered to the condition of outwards slight opening, and the inserting pin is convenient to pull out. Meanwhile, in the inserting and pulling process, a power supply is disconnected. According to electricity utilization requirement, a plurality of inserting sleeves with the function are arranged in a socket so as to form a practical socket system. The power supply socket system is compatible with an existing socket.

Description

[0001] This application is a divisional application of the patent application "A Reliable Contact Plug, Socket and Connector System" (Application No.: 201510937366.6), and the application date is December 12, 2015. technical field [0002] The invention relates to a system for reliable connection of power supply and electrical equipment, especially suitable for electrical equipment requiring large current connection, and belongs to the technical field of electrical equipment and electrical engineering. Background technique [0003] From the analysis of the technical indicators marked in the corresponding standards and specifications such as "Industrial Plugs, Sockets and Couplers" (GB / T 11918-2001), "Connecting Devices for Conductive Charging of Electric Vehicles" (GBT 20234-2011), at present, high-current power supply Plugs, sockets, and connectors used for connection between electrical equipment have some mutually restrictive technical requirements, mainly including: reduci...

AI Technical Summary

Problems solved by technology

From the analysis of the materials recommended in "Industrial Plugs, Sockets and Couplers" (GB / T 11918-2001), materials with high elasticity have high resistance and low conductivity, and are prone to heat during work, causing metal fatigue and hidden dangers during use.

In actual production, composite materials are mainly used, which not only increases the investment, but also increases the cost of production and use, but it still cannot guarantee the effective contact between the socket and the pin.
