Abstract

The present invention relates to a grommet assembly, and more particularly, to a grommet assembly for guiding wiring mounted on a panel of a vehicle, comprising: a grommet body fixable to the panel; a wiring guide penetrating the grommet body and providing a passage through which the wiring is guided; and a rotation guide interposed between the grommet body and the wiring guide and connected to enable the wiring guide to rotate relative to the grommet body. Since the wiring guide can rotate relative to the grommet body by means of the rotation guide interposed between the grommet body and the wiring guide, there is no need to consider any restrictions on the assembly direction of the grommet according to the wiring extraction direction when designing the wiring path, thereby improving the assembly freedom of the grommet and the design freedom of the wiring.

Description

Grommet Assembly The present invention relates to a grommet assembly, and more specifically, to a grommet assembly in which rotation of the wiring guide relative to the grommet body is possible by means of a rotational guide interposed between the grommet body and the wiring guide, thereby eliminating the need to consider any restrictions on the assembly direction of the grommet according to the wiring extraction direction when designing the wiring path, and thereby improving the assembly freedom of the grommet and the design freedom of the wiring. Generally, vehicles are equipped with various electronic components. Electronic components installed in vehicles can be broadly classified into power transmission-related electrical and electronic system components that directly affect the engine's starting system, electronic control system components related to the braking and steering systems, and visibility electrical device components such as headlights and turn signals. These electrical components can typically be connected to corresponding components by wiring via wires, and the wires can be installed in a manner that penetrates the vehicle's panels depending on the location between the connected components. When a wire is installed penetrating a vehicle panel, the wire may be damaged by the inner perimeter corner of the penetration hole formed in the panel, and moisture or foreign substances may enter through the penetration hole; therefore, a grommet, which is a rubber component, is installed in the penetration hole of the panel, and the wire can be passed through the vehicle panel through this grommet. Regarding such conventional grommets, there is a publication in Korean Patent Publication No. 10-2012-0048298. A conventional grommet comprises a housing having a common internal space, a channel penetrating the front and rear of the housing through which a wiring wire for an automobile passes, a hole formed on one side of the grommet housing, and a taping member that seals the front and rear openings of the housing through which the wire passes. However, since these conventional grommets are manufactured as a single unit comprising a housing and a channel made of injection-molded rubber, movement of the channel relative to the housing and overall shape deformation are impossible. Consequently, when designing wiring paths, the assembly direction of the grommet is restricted according to the wiring exit direction, which results in reduced assembly freedom of the grommet and wiring design freedom. In addition, conventional grommets have the problem that the assembly process itself is very cumbersome and difficult because, for accurate fastening to the vehicle panel, unnecessary markings such as arrows must be engraved on one side of the grommet, and the wiring can only be naturally bent and pulled out as intended by the design when the markings are fastened facing a certain direction. In addition, conventional grommets have the problem that the assembly and mounting time on vehicle panels inevitably takes a very long time due to the limited directional flexibility during operation, which can directly lead to a decrease in vehicle productivity. In addition, conventional grommets have a problem in that if they are fastened without adhering to assembly regulations, the wiring passing through the vehicle panel may be flipped or bent in a direction different from the design intent, and if they are forcibly fastened in this state, frequent damage may occur due to interference with surrounding parts and changes in the bending ratio of the wiring.
