Abstract: A connector has a male-side housing provided with terminals and a female-side housing provided with contact portions to contact the terminals. In a state in which the male-side housing and the female-side housing are rotated relative to each other and engaged with each other, the terminals and the contact portions are contact each other to be electrically connected.

Abstract: A connector (11) includes a female terminal (13) having a terminal connection section (19) to which a mating male terminal (17) is electrically connected and a conductor connection section (23) and an electric insulating female-side housing (15) for holding the female terminal (13). The female terminal (13) includes a male terminal insertion/extraction opening (37) bored in the terminal connection section (19) and a plurality of spring contact pieces (41), the fixed-side ends (43) of which are fixed to the opening peripheral section of the male terminal insertion/extraction opening (37) and the free-side ends (45) of which elastically make contact with the male terminal (17) inserted into the male terminal insertion/extraction opening (37).

Abstract: A terminal connection structure for an electric wire includes a first terminal having a first extension section extended from a first connection section in a nearly semi-cylindrical shape and connected to the first terminal member of a mating connection device to be connected to the electric wire and a second terminal having a second extension section extended from a second connection section in a nearly semi-cylindrical shape and connected to the second terminal member of the mating connection device to be connected to the electric wire, the first extension section and the second extension section being disposed coaxially so as to be opposed to each other and to form a nearly cylindrical shape.

Abstract: A cable holding structure includes a plurality of cables, a cable holding member having a plurality of cable receiving grooves for receiving the cables therein, the cable receiving grooves being arranged in parallel with one another, and a belt-like band member that is wound on the cable holding member in a longitudinal direction thereof perpendicular to an extension direction of each of the cable receiving grooves of the cable holding member. The cable holding member is formed to be deformable elastically. The band member is wound on the cable holding member and fixes to bend the cable holding member in a direction to close groove openings of the cable receiving grooves.
