Rotary connector

Abstract

The invention provides a rotary connector, which can simply realize a locking structure of maintaining a movable side case in a rotation neutral position at low price. At the same time, waste materials are not generated because the special unlocking work procedure is not needed. The rotary connector comprises a stop component (10), wherein the stop component (10) is arranged on an outer tube part (4) of a fixed side case (1), and can stop the free rotation of a top plate part (6a) of a movable side case (2). A pair of elastic wrist sheets (13) is clamped on a clamping part (4b) of the outer tube part (4), so the stop component (10) is maintained inside a cut part (6e) of the top plate part (6a) and is inserted into a locking position of a top part (11). The rotary connector rotates to a steering disc after being arranged on a steering device, and the top plate part (6a) exerted with the required rotating force is downwards pressed into the top plate (11). At the same time, because a pair of elastic foot sheets (12) of the stop component (10) generates elastic deformation to be in clamped and buckled combination with a clamping part (4c) of the outer tube part (4), the top part (11) retreats from the inside of the cut part (6e), and the stop component (10) is maintained in the unlocking position.

Description

technical field [0001] The present invention relates to a rotary connector for electrically connecting a rotatably connected fixed-side housing and a movable-side housing through a flexible cable housed in an annular space between the two housings. A locking device that holds the movable side housing at a rotationally neutral position before the rotary connector is mounted on the steering device. Background technique [0002] The rotary connector is generally composed of a fixed-side housing and a movable-side housing that are rotatably connected; and a flexible cable that is accommodated and wound in an annular space formed between the two housings. Both ends of the cable can be connected to an external circuit while being fixed to both housings. In addition, when the movable side housing is rotated in either direction relative to the fixed side housing, the flexible cable will be folded or reversed in the annular space according to the direction of rotation. The electric...

Problems solved by technology

[0010] The former prior art shown in Patent Document 1 has the following problem: when releasing the lock of the movable side case, it is necessary to put a finger on the stopper member or the like mounted on the fixed side case to break it, so the unlocking work is complicated. Lock

In addition, the broken stopper must be discarded, so it is not suitable for waste reduction.

[0011] In contrast, the latter prior art shown in Patent Document 2 has the following problems: Although it has the advantage of not requiring special unlocking work and generating waste, the structure of the locking mechanism is complicated and the number of parts is large, so the cost is high. higher
