Abstract
The invention provides a cable protection sleeve and a cable assembly. The cable protection sleeve includes a threading sleeve body, the periphery of the threading sleeve body is provided with a circular groove, at least one of two groove walls of the circular grove is provided with a sealing skirt edge extending towards the other groove wall opposite to the groove wall and used for pressing against a hole edge of a wire outlet hole, an outer circumferential surface or an inner circumferential surface of the sealing skirt edge is a conical surface used for being pushed by the hole edge of the wire outlet hole and clinging to the hole edge through radial slippage elastic deformation and axial compression elastic deformation so as to seal the wire outlet hole, and the conical surface gradually closes or opens in a direction from front to back. In use, radial and axial deformation of the sealing skirt edge on the groove wall of the circular groove occur when the sealing skirt edge is extruded by the hole edge of the wire outlet hole, and enable the sealing skirt edge to have a very large deformation amount, when deformation of the wall groove of the circular grove occurs due to a swing or bending of a cable, the sealing skirt edge does not completely disengage from the hole edge, thereby ensuring that the sealing skirt edge is capable of clinging to the hole edge at all times, and relatively high sealing waterproofness is achieved.
