A rotary connector device capable of reducing the number of components and enhancing assembly workability provided with: a stationary member; a rotary member to be attached to the stationary member to be capable of relative rotation with respect to the stationary member, the rotary member including a steering wheel insertion hole into which an insertion convex portion of a steering wheel is to be inserted; and an intermediate stationary member provided to be movable between a locked position and a lock released position with respect to the rotary member, wherein the intermediate stationary member is provided with a regulating portion, the regulating portion being configured to, at the locked position, regulate relative rotation of the rotary member when the regulating portion is engaged with the stationary member.

Rotary connector device

A rotary connector apparatus includes: a ring-shaped fixed member; a ring-shaped rotating member rotatably fitted to the fixed member; a flexible flat cable housed in a housing space formed by the fixed member and the rotating member, the flexible flat cable having a plurality of wires, one end of the flexible flat cable being fixed to the fixed member and another end thereof being fixed to the rotating member, wherein a first connector housing attached to the fixed member accommodates a plurality of electrically conductive paths that respectively connect a plurality of first terminals to the plurality of wires at said one end of the flexible flat cable, and at least one of the plurality of electrically conductive paths is configured to removably receive a protection device so as to protect the path from overcurrent.

Rotary connector apparatus

A flat cableaccording to the invention has a plurality of arrayed conductors; and an insulating layercovering the periphery of the conductorswith a coating film, in which the insulating layerincludes a plurality of layers, the outermost layerof the insulating layerand the innermost layercontacting the conductors are both formed from polyphenylene sulfide-based resins, and the melting point of the polyphenylene sulfide-based resin constituting the innermost layeris lower by 5&#xb0; C. or more than the melting point of the polyphenylene sulfide-based resin constituting the outermost layer

Flat cable, rotary connector using the same, and method for producing flat cable

Provided is a flexible flat cable connector that can easily connect a flexible flat cable, and provide a reliable connection. An FFC connector () has a substantially L-shape in cross section and includes a plurality of busbars () made of metal, and a busbar case () made of resin and holding the busbars so that part of the plurality of busbars () is exposed. The busbar case () includes: a recessed portion () configured to accommodate an end portion () of an FFC (); a bottom wall () provided on the recessed portion (); paired side walls () each disposed at both ends of the recessed portion () and facing each other in the width direction of the FFC (); a plurality of protruding portions (A,A, . . . ) provided on the bottom wall (); and paired projections () projecting from the paired side walls (), facing each other, and spaced apart from the bottom wall ().

Flexible flat cable connector, flexible flat cable connection structure, and rotary connector device

A cam section includes a projection section projecting toward an enclosed space enclosed by an outer circumferential cam wall, an inner wall located radially inner to the outer circumferential cam wall, and a coupling cam wall for coupling ends of the outer circumferential cam wall and the inner wall.

Cancel cam structure and rotatable connector device

A rotary connector device includes a stator and a rotator, which relatively rotate with respect to each other. An accommodating space for accommodating cables for electrically connecting the rotator and the stator in a state wound in a circle is formed inside the stator and the rotator is formed. A guide protruding piece which protrudes toward the accommodating space above the cables wound in a circle and which guides the cables from above is formed on an upper portion of an outer peripheral tube portion provided in the stator. A lower surface of the guide protruding piece is formed into a shape which is deformed upward gradually toward a tip.
