Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a hermetic type compressor in which the reliability of sealing performance of a terminal unit is improved, while the terminal unit, which is fixed to a housing, has a raised face and the terminal unit has excellent pressure resistance.SOLUTION: A terminal unit, which closes an opening of a housing, has a terminal pin, a terminal block, and a seal member. The terminal block includes a central part which has a pin insertion hole, a flange part which has a plurality of fastening holes disposed on an outer peripheral side, and a raised face which projects from an inner peripheral side of the flange part in an axial direction of the pin insertion hole toward an inner side of the housing and which has a flange seal surface to abut against a gasket. The central part includes a projection which projects from the flange seal surface toward the inner side of the housing in the axial direction of the pin insertion hole. The seal member extends while exceeding the flange seal surface in the axial direction of the pin insertion hole. An outer end of the seal member is positioned on a side of the housing as compared with a bolt head integrated into one unit with a shaft part or a nut screw-engaged with the shaft part, in the axial direction of the pin insertion hole.
【課題】ハウジングに固定される端子ユニットが平面座を有して優れた耐圧性を有しながら、端子ユニットのシール性の信頼性が向上した密閉型圧縮機を提供する。【解決手段】ハウジングの開口を閉塞する端子ユニットは、端子ピン、端子台及びシール部材を有する。端子台は、ピン挿通孔を有する中央部、複数の締結孔を外周側に有するフランジ部、及び、フランジ部の内周側からピン挿通孔の軸線方向にてハウジングの内側に向かって突出し、ガスケットと当接するフランジシール面を有する平面座を含む。中央部は、ピン挿通孔の軸線方向にて、フランジシール面からハウジングの内側に向かって突出した突出部を含む。シール部材は、ピン挿通孔の軸線方向にて、フランジシール面を超えて延在し、ピン挿通孔の軸線方向にて、シール部材の外端は、軸部と一体のボルトヘッド又は軸部に螺合するナットよりも、ハウジング側に位置している。【選択図】図3 |
