    • In a refrigerant circuit component such as a pressure-sensitive device (pressure switch, pressure sensor, etc.) or valve device, the present invention projection-welds a connector (1) to a cap member (2) and prevents intrusion of spatter into a refrigerant circuit. An A-cylinder section (1a) in which an inside hole (1A) of the connector (1) is open is inserted in an inside hole (2A) formed in the center of the cap member (2). The area between the A-cylinder section (1a) and a projection (11d) of the connector (1) is used as a spatter generation space (β). The projection (11d) of the connector (1) abuts against the cap member (2) and is projection-welded to form a welded part (α). The open end (1A1) of the inside hole (1A) of the A-cylinder section (1a) is crimped to pressure-join the open end (1A1) to the open end (2A1) of the inside hole (2A) of the cap member (2). Spatter is sealed inside the spatter generation space (β). A portion of the surface layer to which the generated spatter adheres may be removed by machining to provide a spatter-removed structure.
    • 在制冷剂回路部件:诸如压敏装置(压力开关,压力传感器等)或阀装置,本发明投影焊接的连接器(1)向盖构件(2),并防止飞溅的侵入 的制冷剂回路。 其中A-气缸部分(1a),以获得连接器的内部(1A)(1)打开时被插入(2A)内的孔形成在所述盖构件(2)的中心。 的A-圆筒部(1a)和所述连接器(1)的一个凸起(11D)之间的区域被用作飞溅发生空间(²)。 所述连接器(1)的凸起(11D)抵接于盖构件(2),并且是凸焊焊接,以形成一个焊接部分(±)。 开口端(1A1)的A-汽缸部(1a)的内孔(1a)的开口端(1A1)被压接至压加入到的内部的孔(2A)的开口端(2A1) 盖部件(2)。 飞溅在飞溅发生空间(²)密封在内部。 表面层的哪个产生的飞溅附着的一部分可以通过机械加工除去,以提供一个飞溅移除的结构。
