Problems solved by technology

The ordinary two-pole grounding plug currently used in the market, that is, the three-pole plug, is used to match the socket. When the electrical appliance is not in use, people usually pull out the plug, and some users will forget or try to save effort. Pulling out, or in some cases with conductive substances such as water stains on the hands, may cause danger when pulling out; or turn off the power switch of the electrical equipment, for the latter, the plug of the electrical appliance is often left on the power socket It will consume power.

Abstract

The invention discloses an overload protector which comprises an assembly body, a metal elastic sheet and a control switch are arranged in the assembly body; one side of the metal elastic sheet is installed in the assembly body and a pin 1 is fixed on the metal elastic sheet. The other side of the metal elastic sheet is mounted on the control switch; a switch through hole matched with the controlswitch is formed in the surface of the assembly body, the control switch is arranged in the switch through hole, a pin 2 is installed in the assembly body and arranged on the side face of the metal elastic piece, and the pin 1 and the pin 2 penetrate through the surface of the assembly body and are arranged outside the assembly body. The overload protector has the advantages that when an overloadphenomenon occurs, the metal elastic sheet automatically acts, deforms and is separated from the pin 2, so that the current is cut off, the equipment is protected from being damaged, and the safety ishigh; a user can drive the metal elastic sheet to act through the control switch, the connection and disconnection of a circuit are manually controlled, and the control is very convenient.

Description

technical field [0001] The invention relates to the related technical field of plugs, in particular to an overload protector. Background technique [0002] Power plug refers to the device that devices such as electrical appliances are connected to power supply. The ordinary two-pole grounding plug currently used in the market, that is, the three-pole plug, is used to match the socket. When the electrical appliance is not in use, people usually pull out the plug, and some users will forget or try to save effort. Pulling out, or in some cases with conductive substances such as water stains on the hands, may cause danger when pulling out; or turn off the power switch of the electrical equipment, for the latter, the plug of the electrical appliance is often left on the power socket It will consume power. At this time, the power supply part of the electrical appliance is actually charged, which is very unsafe. In addition, for electrical appliances without switches, such as rice...
