Abstract

The invention relates to the technical field of electric appliances, in particular to an anti-reverse-plugging structure for protecting an electric appliance, and the structure comprises a switch body which comprises a first plugging part and a second plugging part, and the first plugging part and the second plugging part are symmetrically distributed with respect to an imaginary center line of the switch body; the conductive structure comprises a first conductive part corresponding to the first plugging part and a second conductive part corresponding to the second plugging part; the switch body is also provided with an insertion part, the conductive structure is provided with a protruding part, and the protruding part and the insertion part are matched when the switch body is assembled along a preset direction and are staggered when the switch body is assembled along a non-preset direction; and the preset direction is the direction when the first plugging part corresponds to the first conductive piece. The invention provides an anti-reverse-insertion structure for protecting an electric appliance, which is not easy to reversely connect when a circuit breaker is connected with a cabinet body.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an anti-reverse insertion structure for protecting electrical appliances. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. The existing plug-in type circuit breaker inlet end basically adopts a plug-in wiring structure to connect with the cabinet body, and a plug-in type circuit breaker inlet end usually has two terminals, namely the L pole terminal (live wire terminal, hereinafter referred to as L terminal) and N terminal (neutral terminal, hereinafter referred to as N terminal), usually the L terminal of the circuit breaker is connected to the L terminal in the cabinet, and the N terminal of the circuit breaker is connected to the N terminal in the cabinet. Terminal connectio...
