Description

Sealing glue plug applied to wire harness Technical Field The application relates to the technical field of vehicle accessories, in particular to a sealant plug applied to a wire harness. Background In the automobile lamp assembly process, the wire harness is required to be connected with the inside and the outside of the lamp room through a round through hole preset in the sheet metal part of the automobile body. Due to the size limitations of the harness connector, the standard circular hole diameter provided in the body sheet metal part is typically larger than the harness trunk Outer Diameter (OD), which results in a significant annular gap at the via after harness assembly is completed. In view of the stringent requirements of the automotive lamp for the tightness of the lamp chamber, this gap must be effectively sealed off by means of a special seal. The rubber plugging scheme adopted by the prior art has the obvious technical defect that the structure comprises a through hole matched with a wire harness trunk, and when the rubber material of the structure is contacted with an insulating layer (mostly PVC or XLPE material) covered outside a wire harness lead, the friction coefficient of the two high polymer materials is higher, so that larger friction resistance can be generated in the assembly process, the assembly difficulty is increased, and the assembly efficiency is affected. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes: The utility model provides a be applied to sealed stifled of pencil, includes the stifled body of gluing of being made by elastic material, the outer wall of gluing stifled body is equipped with the annular groove, be equipped with on gluing stifled body and supply wire male through-hole, just be equipped with the sunk structure on the pore wall of through-hole. The technical scheme of the embodiment of the utility model for solving the technical problems is that the concave structure forms a wave structure on the wall of the through hole, and the lead is inserted into the through hole and is propped against the crest of the wave structure. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the side groove wall of the annular groove is an inclined surface, and the outer side of the side groove wall is inclined towards the direction close to the groove wall of the other side. The technical scheme includes that the glue plug body comprises a first section and a second section which are connected with each other, the first section is located on one side, close to a lamp chamber, of the second section, the outer diameter of the first section is smaller than that of the second section, and annular grooves are distributed between the first section and the second section. The technical scheme of the embodiment of the utility model for solving the technical problems is that a first concave hole is formed in the middle of one side, close to a lamp room, of the glue plug body, and the through hole is formed in the periphery of the through hole. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that a second concave hole is formed in the middle of one side, far away from the lamp room, of the glue plug body. The technical scheme of the embodiment of the utility model for solving the technical problems is that an annular groove is arranged on the bottom wall of the second concave hole, and an annular boss matched with the annular groove is arranged on the sheet metal part of the vehicle body. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the cross section of the annular groove is conical. The wire harness sealing device has the beneficial effects that the concave structure is designed on the hole wall of the through hole, the wire is propped against the hole wall of the through hole after being inserted into the through hole due to the certain elastic deformation capability of the sealing glue plug, so that the through hole is in sealing contact with the wire harness, the sealing performance is ensured, the concave part is not in contact with the wire harness when the wire harness is inserted into the through hole, the contact area between the wire harness and the inner wall of the through hole is reduced, the friction resistance of the wire harness when the wire harness is assembled into the inner wall of the through hole is reduced, the wire harness is conveniently inserted into the through hole, and the assembly efficiency is improved.
