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...

Examples

Embodiment 1

[0033] Such as figure 1 As shown, a control type safety socket of this embodiment includes a housing (6), a socket contact piece (1), an incoming line contact piece (3) and a linkage contact device; the housing (6) is divided into an upper The shell (601), the middle shell; the upper shell (601) is provided with a socket, and the inner side is provided with a slot (6011) for clamping the power baffle (4), and the upper end of the power baffle (4) is snapped into the slot ( 6011) to enhance the stability of the power baffle (4); the linkage contact device includes a power slider (201), a tail, a spring (5) and a power baffle (4), and the power slider (201) is an insulator , along the plug insertion direction is conducive to the smooth surface of the plug insertion, the power slider (201) is located in the seat body (101) close to the socket contact pin part (102) side; the tail part includes the tail rod (202) and the limit part (203), located on the side where the power slide...

Embodiment 2

[0035] The specific structure of the pair-controlled safety socket of this embodiment is basically the same as that of Embodiment 1, the difference is that: the outer shell (6) includes an upper shell (601), a middle shell and a lower shell, and the incoming line contacts ( 3) One end installed with terminals passes through the lower opening of the middle shell and is fixedly connected with the middle shell, and the lower shell is fixed at the bottom of the middle shell to protect and isolate the incoming line contact piece (3) and the wiring terminals, so that the socket structure is more compact .

Embodiment 3

[0037] The specific structure of the pair-controlled safety socket of this embodiment is basically the same as that of Embodiment 1, the difference is that: the contact piece (3) of the incoming line and the pin part (102) of the contact piece of the socket are located in the linkage contact device One side; the linkage contact device includes a power slider (201) and a tail, and the linkage contact device is fixedly connected with the incoming line contact (3) or the socket contact pin (102) through the tail, and through the linkage Move and squeeze to connect the incoming contact piece (3) with the pin part of the socket contact piece (102) to connect the circuit, and realize the reset by the elasticity of the incoming line contact piece (3) or the socket contact piece pin part (102) itself .
