Intelligent tripping-preventive power supply device

Abstract

The invention discloses an intelligent tripping-preventive power supply device. The power supply device comprises an upper casing, a pedestal, four jack assemblies into which flat insertion pieces of a plug are inserted, an unlocking ring and an unlocking rod; and each jack assembly comprises a sub-casing, a self-locking piece, a self-locking rod, a sleeve into which the flat insertion piece is inserted, a copper bearing, a conductive connecting piece and a conductive rod. Thus, two jacks, except a jack connected to a ground wire, among three jacks of each group can rotate in the surface of the upper casing around an intersection point of two diagonals of a rectangular opening of the jack, so that both three-pole and two-pole flat plugs can be inserted into the three-pole jack, two three-pole flat plugs or two two-pole flat plugs or one three-pole flat plug and one two-pole flat plug can be inserted into the power supply device at the same time, and the using convenience of the power supply device is improved.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an intelligent anti-pull-off power supply device. Background technique [0002] At present, indoor power supply devices are mostly sockets. There are many kinds of sockets, including wall sockets fixed on indoor walls. At present, the most widely used is the five-hole wall socket, such as figure 1 As shown, the five-hole wall socket includes a set of two-pole jacks suitable for a two-pole flat plug or a two-pole round plug and a set of three-pole jacks suitable for a three-pole flat plug. The jack has a built-in sleeve that is plugged in with the blade on the plug, and the sleeve is connected to the corresponding neutral wire, live wire or ground wire. Obviously, the five-hole socket can only insert a three-pole plug and a two-pole plug at most at the same time. When the three-pole jack is occupied, the remaining two-pole jacks cannot be inserted into the three-...

AI Technical Summary

Problems solved by technology

With the increase of electrical products, in daily life, the following situation often occurs: the power plug of the electrical appliance to be used is a three-pole flat plug, but there is only one set of two-pole jacks left on the five-hole socket near the electrical appliance , resulting in that the three-pole flat plug cannot be inserted into the five-hole socket, so one can only search for a three-pole socket on a distant five-hole socket; or the power plug of the electrical appliance to be used is a two-pole plug, but the power There is only one set of three-pole jacks left on the five-hole socket near the electrical appliance, so the two-pole plug cannot be inserted into the five-hole socket, so we can only look for two-pole jacks on the five-hole socket far away; It is very common in daily life, exposing the inconvenient defect of the five-hole socket
