The IBM System 360 and 370 I/O channel to control unit interconnection, widely adopted in the data processing industry, defines certain signal cabling and connectors. The connector block and contact used are hermaphroditic components. The usual contact, known in the industry as the "serpentine" contact, offers three methods of connection: 1. crimping onto a wire, 2. crimping onto a straight pin, then soldering the assembly onto a printed circuit board, and 3. soldering a one-piece serpentine contact with an integral solder tail directly onto a printed circuit board. An improved serpentine contact with a compliant section tail is described herein. The improved contact illustrated in the figure is press-fitted into a printed circuit board, "complying" with the shape of the plated- through hole.
