Abstract: According to one embodiment, a printed circuit board is provided with a printed wiring board and a circuit component mounted on the printed wiring board. The printed wiring board includes a first surface on which the circuit component is set, a second surface formed on the reverse side of the first surface, and a through hole formed penetrating the printed wiring board from the first surface to the second surface. The circuit component includes a projected portion to be inserted into the through hole. The projected portion is deformable between a first state in which a distal end of the projected portion projects to the outside of the printed wiring board beyond the second surface and a second state in which the distal end of the projected portion is situated in the through hole.

Abstract: According to one embodiment, a printed circuit board includes a printed wiring board and a connector. The connector includes a housing, a lead received inside the housing, an insertion section which is provided in the housing and to which the printed wiring board is inserted, and a rotating mechanism. The rotating mechanism moves the lead to a first position in which the lead is separated from the printed wiring board by abutting the lead and moves the lead to a second position in which the lead is connected to the pad of the printed wiring board via the solder by rotating and separating from the lead when the printed wiring board is inserted into the insertion section.

Abstract: According to one embodiment, a connector device includes a flexible cable, a housing, a containing portion, a wall portion, and a leaf spring. The containing portion is formed inside the housing, and a terminal of a counter connector device is inserted to the containing portion. The wall portion is opposed to the flexible cable, and forms one surface of the containing portion. The leaf spring is provided inside the containing portion, and adhered to a surface of the flexible cable reverse to a surface in which a conductor portion of the flexible cable is exposed. The leaf spring urges the flexible cable toward the wall portion to hold the terminal with the wall portion.
