Embodiment Construction

[0027] One mode for implementing the present invention will be described below using the drawings.

[0028] figure 1 It is the front view of the end part of the flat cable 11 which is the main part of the present invention, figure 2 It is a perspective view of the rotary connector device 21 that accommodates the flat cable 11 .

[0029] This rotary joint device 21 is disposed on a pillar portion of an automobile. Specifically, the rotary connector device 21 is disposed between a steering wheel (not shown) and a combination switch (not shown).

[0030] First, a schematic structure of the entire rotary connector device 21 will be described.

[0031] The rotary connector device 21 is provided with: a stator 31 as a fixed side member located on the lower surface side; a rotor 41 located on the upper surface side as a part of the rotating side member; The rotation lock unit 51 which is a part of the rotation side member holds the neutral position of 31 (the neutral position o...

Abstract

In a rotatable connector device, generation of an unusual sound, which would otherwise be caused by contact during the rotation of a rotator, is prevented without, for example, complicating the structure of terminal conductors; and also another advantage is provided. A rotatable connector device 21 includes a stator 31 and a rotator 41; and also has a fixed-side cable end accommodation section 34, projecting from an outer circumferential surface of the stator 31 in a tangential direction thereof, for accommodating and holding a mold section 16 provided at a fixed-side end of a flat cable 11 accommodated in the rotatable connector device 21. In a portion of the flat cable 11 on the side of the fixed-side mold section 16, a bent portion 12 which is folded to be shortened so as to shift a fixed-side end 11a in a width direction of the flat cable 11, resulting in the flat cable 11 being shortened in a longitudinal direction thereof, is formed by a trough line 12a and a ridge line 12b parallel to each other and extending in a direction crossing the longitudinal direction of the flat cable 11.

Description

technical field [0001] The present invention relates to a rotary connector device, and more specifically, relates to a connector device capable of preventing the generation of abnormal noise. Background technique [0002] The rotary connector device includes a fixed-side member and a rotary-side member attached so as to be relatively rotatable with respect to the fixed-side member. A rotary connector device for electrically connecting a vehicle body and a steering wheel of an automobile includes a fixed side member fixed to the vehicle body and a rotary side member fixed to the steering wheel so that it cannot rotate relative to the steering wheel. [0003] And, these fixed side members and rotating side members are connected by flat cables. Both ends of the flat cable are provided with terminal conductor connection portions for holding terminal conductors constituted by bus bars, and the terminal conductor connection portions are respectively held by the fixed-side member ...
