Clock spring with rotating locking mechanism

Abstract

The invention relates to a clock spring with a rotating locking mechanism. The clock spring is provided with an end cover and a locking part, a casing is covered on the end cover, a coil core is arranged in the casing, a poking part is installed on the lower portion of the end cover, the poking part and the coil core are fastened to form a rotating mechanism, the locking part is provided with a locking handle and an insertion part extending downwards, a hollow rectangular block is fixed on the coil core, the locking part and the rectangular block form the rotating locking mechanism, and one side face of the rectangular block is provided with an opening. A half of the top surface of the rectangular block is open, and a through hole is arranged at the position close to a corner in the opening. The through hole penetrates through the coil core, the poking part and the end cover, the locking part is provided with a clamping buckle extending towards one side, the clamping buckle is clamped in the rectangular block and can rotate in the rectangular block, and the insertion part is inserted into the through hole to penetrate through the coil core, the poking part and the end cover. The clock spring with the rotating locking mechanism is simple in structure, easy to achieve and firm to install and cannot loose or drop easily in the vehicle transporation process, the failure rate of the clock spring prior to zero kilometer is reduced, and the service life of the clock spring is prolonged.

Description

technical field [0001] The invention relates to a clock spring, in particular to a clock spring with a rotation locking mechanism. Background technique [0002] The clock spring is an electrical rotary connector used for the steering wheel airbag and its control system. It is usually installed under the steering wheel, above the combination switch or the steering column tray. The clock spring is generally provided with an end cover, and a cover shell is added to the end cover Body to form a stator mechanism, then install a coil core on the upper part of the housing, install a pulling piece on the lower end of the end cover, and form a rotating mechanism by fastening the coil core and the pulling piece, and then, by The cooperation between the stator mechanism and the rotating mechanism forms a cavity inside, and a rotating roller frame mechanism with rollers is installed in the cavity, and then the two sides of the flat cable are connected to the wire harness by welding, and...

AI Technical Summary

Problems solved by technology

The above-mentioned clock spring is commonly used now, but it often causes the locking part to loosen or fall off due to accidental factors or human manipulation during transportation, causing the rotation mechanism of the clock spring to deviate from the center point, resulting in a high loading failure rate. Reduced clockspring lifespan
