Abstract
An inverter includes a housing and a first connector, where a circuit board is disposed on an inner side of the housing, and an inverter circuit is disposed in the circuit board. The first connector includes a first housing and a first conductive core. The first housing is fastened to the housing. The first conductive core is located in the first housing and extends into the inner side of the housing. The first conductive core includes a first connecting plate located on the inner side of the housing. The first connecting plate is of a flat structure. The first connecting plate can be connected to the circuit board without a cable.
