Grommet for engine hood cable stay wire
The invention relates to a grommet for an engine hood cable stay wire. The grommet comprises a sleeve part; the installation part and the sleeve part are formed at the two ends of the grommet respectively, the installation part is of a conical structure with the diameter gradually increased in the direction close to the sleeve part so as to form an insertion end with the small diameter and an extrusion end with the large diameter, and an extrusion notch is formed in the circumferential outer wall of the installation part; one end of the extrusion notch extends to the peripheral edge of the extrusion end and correspondingly forms a compression arc section on the peripheral edge of the extrusion end; the sealing lip is arranged between the extrusion end and the mounting part; the annular clamping groove is formed between the extrusion end and the sealing lip edge and is coaxial with the mounting part, and the radius of the groove bottom of the annular clamping groove is smaller than the radius of the extrusion end and the radius of the sealing lip edge. In the process that the grommet is pressed and inserted into the metal plate hole of the front wall plate, the mounting part firstly penetrates through the metal plate hole until the outer wall abuts against the inner edge of the metal plate hole, the grommet is continuously pressed, the mounting part is deformed and compressed towards the interior of the extrusion notch, the magnitude of interference can be reduced, and the difficulty of manual mounting of operators is reduced.
本申请涉及一种发动机罩索拉线用索环，其包括：套管部；安装部，其与套管部分别成型于索环的两端，其呈在靠近套管部的方向上直径逐渐增大的锥形结构，以形成直径较小的插入端与直径较大的挤压端，其周向外壁设有挤压缺口，挤压缺口一端延伸至挤压端周沿并在挤压端的周沿上对应形成压缩弧段；密封唇边，其设于挤压端与安装部之间；环形卡槽，其设于挤压端与密封唇边之间，其与安装部同轴且其槽底半径小于挤压端以及密封唇边的半径。将索环按压插接至前围板钣金孔的过程中，安装部率先穿过钣金孔直至外壁与钣金孔内沿抵紧，继续按压索环，安装部则将向挤压缺口内形变压缩，即可减小过盈量，实现降低操作人员在人工安装时的困难度。
