Abstract: A contact in one aspect of the present disclosure comprises a fixing portion, an elastic contact piece, and a pair of projecting tabs, which are formed as an integrated entity from a metal thin plate. The projecting tabs project from the fixing portion at positions on both sides of the elastic contact piece. A dimension of the elastic contact piece in a width direction, which matches the direction of an interval between the projecting tabs, is a first dimension. The projecting tabs are formed such that each projecting tab is a flat plate having the same thickness as the thin plate. The projecting tabs are arranged such that the thickness directions thereof are the same direction, in locations that have inner surfaces of the projecting tabs facing each other, and an interval between the inner surfaces is a second dimension greater than the first dimension.

Abstract: A pair of solder bonding portions to be solder-bonded onto the printed wiring board and a contact portion to contact the different conductive member or the like are coupled by a pair of flat spring portions. The respective flat spring portions protrude from side surfaces of mutually opposed corners of the contact portion. Sections following protruded sections of the respective flat spring portions are bent so as to wind in the same direction around a pillar-shaped space obtained by projecting the contact portion downward, and the flat spring portions reach the corresponding solder bonding portions. When the contact portion is pressed by the conductive member, the contact portion and the solder bonding portions remain parallel to each other, whereby the contact member can be successfully flattened toward the printed wiring board. At this point, outward deformation of the flat spring portions is inhibited.

Abstract: A contact includes a thin plate member having elasticity and conductivity, is disposed between a first member and a second member, and electrically connects the first member and the second member via the thin plate member, and the contact includes a base portion and a movable portion. The base portion has a bonding surface to be bonded to the first member by soldering. The movable portion includes: a contact portion that contacts with the second member; and a connecting portion that connects to the base portion, and is configured to be elastically deformable with respect to the base portion. The connecting portion is gradually separated from the first member. A predetermined range from a connecting position of the connecting portion with the base portion is lower in solder wettability than the bonding surface.

Abstract: A contact member for which downsizing beyond conventional products is feasible is provided. The contact member includes a base portion, a contact portion, and a spring portion. The spring portion includes a first extension portion, a second extension portion, a third extension portion, and a fourth extension portion. The first extension portion is bent from a rear end of the base portion and extends upward. The second extension portion is bent from an upper end of the first extension portion and extends forward, and its upper surface is made to be a sucked surface that is capable of being attracted to a suction nozzle of an automatic mounting machine. The third extension portion is bent from a front end of the second extension portion and extends forward obliquely downward. The fourth extension portion is bent from a front end of the third extension portion, extends upward obliquely rearward, and is provided with the contact portion on a distal end side in its extension direction.
