Single-hole automatic positioning ground wire-free electrical plug socket assembly

Abstract

The invention discloses a single-hole automatic positioning electrical plug and socket assembly without a ground wire. The plug and socket assembly includes: a plug and a socket. A neutral pole ring with a certain distance between the poles, the socket includes a jack matching one of the live poles, an annular slot matching the neutral pole ring, and the outer circumference of the neutral pole ring surrounds A retractable insulation protection cover; the retractable insulation protection cover in the present invention is convenient to protect the exposed plug and can prevent the occurrence of electric shock accidents; Automatic positioning of the socket; the present invention will have a huge impact on the use of sockets for disadvantaged groups, and is convenient for people with vision problems, the elderly and children, and can produce good economic and safety benefits.

Description

technical field [0001] The invention relates to a combination of electric wiring devices of a mobile electric appliance, in particular to a single-hole automatic positioning electric plug and socket assembly without a ground wire. Background technique [0002] In the prior art, in general household two-hole or three-hole plug-and-socket combinations, the plug is generally directly inserted into the socket, such as Figure 1-3 As shown, a two-hole plug-socket combination without a ground wire requires the user to align the two electrode columns 11' of the plug 10' with the two jacks 21' of the socket 20', and then forcefully Insert the plug 10' into the socket 20', but it is inconvenient for users with poor eyesight or people with trembling hands, and because the electrodes of the plug 10' are exposed, electric shock accidents are prone to occur. [0003] Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0004]...
