Safety socket

Abstract

The invention discloses a safety socket comprising a power supply. A detection circuit is arranged at each jack panel and is used for detecting a load access situation of the corresponding jack panel. The detection circuit consists of an access determination module and an off determination module, so that a good protection effect is realized and security and stability of the whole circuit are improved. Meanwhile, if a finger of a person is inserted into a socket jack, no loop can be formed and the access determination module does not work, so that no potential safety hazard occurs; but a current source circuit will output a weak current and the load of the insertion part is detected; when the load is close to a human body load, existence of the human body is determined, wherein the body resistance can be 1000 to 2000 ohm; and thus the socket is not electrified, so that the security of the human body is guaranteed. Besides, because the human body is not a pure resistor unit, the impedance exists; and thus a time-delay circuit is set to reduce the interference on determination by the impedance.

Description

technical field [0001] The invention relates to a safety socket. Background technique [0002] Sockets are generally used in many households, but the current sockets still cannot solve the problem of potential safety hazards very well. For example, if a finger is directly inserted into the socket hole and forms a loop, it is easy to cause potential safety hazards of electric shock. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a socket that distinguishes between normal loads and human bodies through detection, and ensures the safety of human bodies. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a safety socket, including a power supply, characterized in that, [0005] Each jack panel is provided with a detection circuit, and the detection circuit is used to detect the load access condition of the corresponding jack panel, ...
