Title: VIBRATION TYPE COMPRESSOR
Abstract:
Provided is a vibration type compressor in which a piston that is reciprocatably supported by a casing having a yoke pipe via a pair of resonant springs is slidably engaged with a cylinder that is coaxially fixed to the casing, and a drive coil that is provided coaxially with the piston in a magnetic field is connected to the piston, wherein a metallic disk-shaped connecting plate (54) that is fixed to a piston (21) before being bonded to a plastic bobbin (53) that supports the drive coil is coaxially mold-bonded to the bobbin (53); and a pair of terminals (61, 62) that have abutment connection portions (61a, 62a) against which metallic resonant springs (22, 23) functioning as conductive members are made to abut and that are respectively connected to both ends of the drive coil are bonded such that the abutment connection portions (61a, 62a) are made to face both axis-wise ends of the bobbin (53). Accordingly, it is possible to achieve an improvement in the assembly work accuracy while easily improving the concentric accuracy of the drive coil and the piston.
