Title:
WELD STRUCTURE FOR REFRIGERANT CIRCUIT COMPONENT AND WELDING METHOD FOR REFRIGERANT CIRCUIT COMPONENT
Document Type and Number:
WIPO Patent Application WO/2014/097687
Kind Code:
A1
Abstract:
In a refrigerant circuit component such as a pressure-sensing 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 the refrigerant circuit. An A-cylinder section (1a) in which an inside hole (1A) of the connector (1) is open is inserted inside 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 called a spatter generation space (β). The projection (11d) of the connector (1) is abutted against the cap member (2) and projection-welded to form a weld zone (α). The open end (1A1) of the inside hole (1A) of the A-cylinder section (1a) is crimped to pressure-weld the open end (1A1) to the open edge (2A1) of the inside hole (2A) of the cap member (2). Spatter is sealed inside the spatter generation space (β). It is also possible to remove a portion of the surface layer to form structures from which spatter has been removed by machining areas in which spatter has been generated and is adhering.
