BOBBIN OF LINEAR COMPRESSOR

摘要

PURPOSE: A bobbin of a linear compressor is provided to maintain regular deviation from roundness and cylindricity of a bobbin. CONSTITUTION: A bobbin(50) includes a main body(51) having external cores accumulated on a circumference, forming the concentricity, and a cylindrical coil wound part(53) on which a coil is wound. A reinforcing member(52) is installed on an inner peripheral surface of the coil wound part and is formed of a metal material to prevent the coil wound part from being deformed by a winding pressure of the coil. Guide protrusions(58) are formed on the inner peripheral surface of the reinforcing member to guide the cores. The bobbin is injection-molded integratedly with the reinforcing member.
