An electric shock-proof household power supply device for children

Abstract

A household power supply device preventing electric shock to children comprises an upper case, a base, and two three-pole jack assemblies. Each three-pole jack assembly comprises a primary rotating case, a protective door, two single-pole jack assemblies for a flat insert of a plug to be inserted into, an unlocking ring, an unlocking rod, a first L-shaped conductive bar, a first copper bearing, a second copper bearing, and a third copper bearing. Each single-pole jack assembly comprises a secondary rotating case, a self-locking piece, a self-locking rod, a plug bush for a flat insert to be inserted into, a fourth copper bearing, a conductive connector, and a second L-shaped conductive bar. Due to the arrangement, the two rotating jacks in each three-pole jack assembly can rotate on the surface of a middle partition about the intersections of the two diagonals of rectangular openings thereof, so that both a three-pole flat plug and a two-pole flat plug can be inserted into the three-pole jacks, and the convenience in using the power supply device is improved.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a child-proof household 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-pole ...

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
