Abstract
The invention provides a linear compressor, comprising a housing, and a wiring component used to provide external electric connection for the device in the housing. The housing is provided with a first end face region and a second end face region respectively on two axial ends of the housing, a peripheral region on the middle part of the axial direction of the housing, a first annular transition region between the first end face region and the peripheral region, and a second annular transition region between the second end face region and the peripheral region. At least a part of the wiring component is installed on the first annular transition region or the second annular transition region of the housing. The linear compressor is compact in space arrangement, and can prevent a cylinder cover and an air intake noise reduction cavity from impacting with binding posts. The housing shell dimensions are not needed to be expanded on a length direction, so as to save space and reduce cost.
