An inverter assembly is disclosed and includes a base, a contact terminal, an output copper busbar and an elastic component. The output copper busbar is disposed on the base. The output copper busbar includes an output portion configured to electrically connect with the contact terminal. The elastic component is disposed on the base and includes an abutting element, an elastic element and an accommodation seat. The accommodation seat is disposed on the base, the abutting element is connected to the accommodation seat through the elastic element along an axial direction. When the base is docked with the contact terminal, the abutting element of the elastic component abuts against the output portion to attach to the contact terminal, and the contact terminal abuts against the abutting element and the elastic element, so that a restoring force provided by the elastic element keeps the output portion abutting against the contact terminal.
