Abstract

The invention discloses a rotary connector having a thin-type buckling connection structure. The buckling connector comprises a fixed side shell body, a movable side shell body, a flat cable, lead wire blocks and an electric wire harness, wherein the fixed side shell body comprises an outer cylinder portion and a bottom plate component; the movable side shell body comprises an inner cylinder portion and a top plate part which is opposite to the bottom plate component, and the movable side shell body is connected with the fixed side shell body in a free rotating manner; the flat cable winds in an annular space between the outer cylinder portion and the inner cylinder portion; the lead wire blocks are installed and fixed to the fixed side shell body and the movable side shell body; the electric wire harness is electrically connected with lead wire blocks, and is connected with the flat cable through connecting terminals in the lead wire blocks; an opening is formed in the top plate part, the top plate part comprises a cover component covering the opening, and the cover component is installed on the top plate part through the buckling connection structure; and the buckling connection structure comprises a first buckling part and a second buckling part, and buckling operation of the buckling connection structure is carried out by utilizing elastic deformation of at least anyone of the first buckling part and the second buckling part in an orthogonal plane which is orthogonal to a rotating shaft direction of the movable side shell body.

Description

technical field [0001] The present invention relates to a rotary connector equipped in a steering device of an automobile and used as an electrical connection mechanism for an airbag system, and more particularly to a rotary connector having a thinned snap-fit ​​structure. Background technique [0002] A rotary connector generally includes a fixed-side housing having an outer cylindrical portion, a movable-side housing having an inner cylindrical portion that is rotatably connected to the fixed-side housing, and a coil that can be wound up or unwound. A flat cable wound in an annular space provided between the outer cylindrical portion and the inner cylindrical portion. An external connector for electrically connecting the flat cable and various steering switch circuits is provided on the movable side case. The external connector is provided with a resin cover for preventing intrusion of dust into the inside. [0003] Such a resin cover is usually attached by a snap connec...
