Abstract: A board-to-board connector includes a receptacle and a plug for inserting into the receptacle. The receptacle includes a receptacle insulator including two opposed side walls and opposed receptacle contacts symmetrically arranged and supported by the two opposed side walls. Each of the two opposed receptacle contacts includes an inverted U-shaped portion and a U-shape-grooved continuity. The plug includes a plug insulator including two opposed insert walls and opposed plug contacts symmetrically arranged and supported by the two opposed insert walls. Each of the two opposed plug contacts includes a U-shaped continuity portion and is inserted into the U-shape-grooved continuity portion to establish electrical connection therewith. When the plug is inserted into the receptacle, the U-shaped continuity portions of the two opposed plug contacts deform the U-shape-grooved continuity portions of the two opposed receptacle contacts resiliently away from the two opposed side walls of the receptacle insulator.

Abstract: A pin carrier for locating male contact pins on a printed circuit board (PCB) with a very high degree of accuracy, while placing a very low thermal mass in contact with each male contact pin. The pin carrier has a plurality of chimney structures, each chimney structure configured to retain one male contact pin. Male contact pins are inserted into each chimney such that essentially only that portion of the male contact pin which is to enter the PCB is exposed. The male contact pins are held in the chimney by a frictional retention force just sufficient to maintain the male contact pins securely within the chimneys during shipment and soldering onto a PCB, but not so great as to make removal of the pin carrier difficult after the male contact pins have been soldered to a PCB. In addition to registering the pins while maintaining a low thermal mass, the chimney structure also protects the male contact pin from excessive solder flow due to solder wicking, and from the corrosive effects of solder flux.
