Abstract
A plug assembly includes a plug body defining at least one mounting through hole and at least one a connecting post passing through the mounting through hole. Each connecting post has a first end located in the mounting through hole to be configured for plug-in connection with a terminal of a compressor, and a second end extending beyond the mounting through hole to be configured for connection with a control board. A compressor starter can include the plug assembly. A compressor assembly can include the compressor starter.
Claims21
A plug assembly comprising:
- a plug body defining at least one mounting through hole extending through the plug body;
- and
- at least one connecting post passing through the mounting through hole, the connecting post having a first end located in the mounting through hole to be configured for plug-in connection with a terminal of a compressor, and a second end extending beyond the mounting through hole to be configured for connection with a control board,
- wherein:
- the at least one mounting through hole comprises three mounting through holes arranged in a triangle;
- the plug body comprises three mounting portions spaced apart from one another and arranged in parallel in an axial direction;
- each of the mounting portions defines one of the mounting through holes through in the axial direction of the mounting portion, and the three mounting portions are connected by three first connection plates and three second connection plates;
- first ends of the three first connection plates are connected and coincide with an incenter of a triangle formed by the connection lines of the centers of the three mounting portions, and a second end of each of the three first connection plates is connected with an outer peripheral wall of the corresponding mounting portion;
- and
- two adjacent mounting portions are connected by the second connection plate, and the three first connection plates are located at an inner side of a structure formed by the three second connection plates and the three mounting portions.
