Abstract

The invention discloses a time-delay power-on protection structure for a socket. The time-delay power-on protection structure comprises a socket body and a plug, wherein a slot corresponding to an insertion piece in the plug is formed in the socket body, a first connecting plate and a second connecting plate are slidably connected in the slot, a guide rod is fixedly connected to one side, away from the plug, of the first connecting plate, the guide rod penetrates through the second connecting plate and the inner wall of the slot, the section, away from the first connecting plate, of the guide rod is fixedly connected with a rack, the rack is meshed with a gear, the rotation center of the gear is fixedly connected with a threaded shaft, a first cavity and a second cavity are formed in the socket body, and the threaded shaft penetrates through the first cavity and the second cavity. According to the invention, when an electric appliance is connected with a circuit, the current of the electric appliance is slowly increased until the current is increased to a working current, so that the circuit is protected, and when the circuit is quickly connected, a time-delay electrifying effect is achieved, and electric shock is avoided.

Description

technical field [0001] The invention relates to the field of sockets, in particular to a delayed power-on protection structure for sockets. Background technique [0002] Also known as supply socket and switched socket, English translation: Socket. Socket refers to the insertable seat of one or more circuit connections, can insert various wiring by it, is convenient to connect with other circuits like this. Through the connection and disconnection between the line and the copper parts, the final connection and disconnection of the part of the circuit is achieved. [0003] In the prior art, for the plug-in use of high-power electrical appliances, the phenomenon of unstable connection is prone to occur, and the problem of electric sparks will occur when the connection is unstable, and it is easy to affect the insulation of the socket after long-term use. When the circuit is connected, the current in the electrical appliance changes from zero to the maximum, and when the power...
