Single-jack automatic locating electrical plug and socket assembly having ground wire

Abstract

The invention discloses a single-jack automatic locating electrical plug and socket assembly having a ground wire. The plug and socket assembly comprises a plug and a socket. The plug comprises a live wire pole, a zero wire polar ring which surrounds the live wire pole and is spaced from the live wire pole for a certain distance, and a ground wire polar ring which surrounds the zero wire polar ring and is spaced from the zero wire polar ring for a certain distance. The socket comprises a jack which is matched with the live wire pole, a first ring slot which is matched with the zero wire polar ring and a second ring slot which is matched with the ground wire polar ring. The external circumference of the ground wire polar ring is surrounded by a telescopic insulating protective cover. The bare plug can be protected by the telescopic insulating protective cover so that the electric shock accident can be prevented. The plug and socket assembly has a significant impact on the socket use mode of the vulnerable group so that use is facilitated for the people with vision problems and the elders and the children, and the great economic and safety benefits can be generated.

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 with 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-and-socket combination with a ground wire is used. After the user aligns the two electrode columns 11' of the plug 10' with the two jacks 21' of the socket 20', forcefully pull the The plug 10' is inserted 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 ...
