Opposite-control type safety socket

Abstract

The invention provides an opposite-control type safety socket. The safety socket comprises a shell, a linkage contact device, socket contacts and wire-inlet contacts, the linkage contact device comprises power slide blocks, springs and a power baffle, each socket contact comprises a base body portion and a pin portion, and each power slide block comprises a triggering portion, a tail rod, and a limiting portion. The power slide block is located at the inner side of the socket contact close to the pin portion of the socket contact in a non-usage state; the power slide block realizes reciprocating motion in the limiting condition through the effect of the tail rod and the limiting portion and the spring and the power baffle, and the pin portion of the socket contact extends to the moving direction of the power slide block in the other socket contact and is located at the side of the wire-inlet contacts or located at an extending line of the wire-inlet contacts; when a foreign matter is inserted into a jack or the power slide block is in a normal usage state, an object inserted into the jack enables the linkage contact device to generate displacement extrusion or enables the connection of the pin portion of the socket contact and the wire-inlet contact so that a path is formed, the other jack is connected to the circuit, and the socket contact in the jack at the side is still in a switch-off state; and during normal usage, two pins of a plug respectively enable the opposite sides to be connected to the circuit through the linkage contact device so that normal usage is realized. According to the safety socket, an opposite-control type scheme is proposed according to the research that children security events caused by sockets are mostly caused by the fact that children hold conductors into the single jacks, the circuit connection condition in the jacks can be effectively controlled, and hidden risks generated by mistaken insertion into the jacks by the children are prevented.

Description

technical field [0001] The invention belongs to the field of electrical sockets, and more specifically relates to a pair-controlled safety socket. Background technique [0002] As a medium for modern electrification equipment to connect to circuits, sockets are widely used in daily life, and the voltage of household electrical appliances in my country is 220V, which belongs to the voltage level that can cause harm to the human body. Electric shock accidents of infants and young children in daily life have made people pay more attention to the safety of electricity use. In order to protect infants and young children from electric shock accidents caused by accidentally poking sockets with foreign objects due to curiosity, various safety sockets have appeared on the market. Board and time-delay sockets are the most widely used, but the plastic baffle is designed to prevent accidental touch by infants and young children, so as to set a large resistance of the plastic baffle to p...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing safety socket cannot realize the on-off of the circuit in the socket jack, resulting in poor protection effect or high cost of the safety socket with electronic delay design, and provides a pair-controlled safety socket; The invention proposes a counter-control scheme by studying the safety incidents caused by children's sockets, which are mostly children holding conductors into a single socket, which can effectively control the connection status of the circuit in the socket, so as to achieve a higher protection effect; the present invention Simple structure, low cost, easy to popularize and use
