Embodiment 1

[0022] Embodiment 1 of the cable assembly of the present invention: it includes a cable and a cable protective sheath covering the cable, wherein the structure of the cable protective sheath is as follows Figure 1-3 As shown, it includes a threading sleeve body 1 extending forward and backward. The threading sleeve body is made of elastic material. The center of the threading sleeve body is provided with a central threading hole 3 extending forward and backward for the cable 8 to be worn. The diameter of the central threading hole is unchanged and basically equal to the diameter of the cable, the outer circumference of the threading sleeve 1 is provided with a ring groove 6 near the front end, and the ring groove 6 is used to snap fit with the hole of the outlet hole and fix the sleeve on the On the fixed plate 7 where the outlet hole is located, among the front and rear sides of the ring groove 6, the front side groove wall 61 is a vertical wall structure perpendicular to the...

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.

Description

technical field [0001] The invention relates to a cable protective cover and a cable assembly. Background technique [0002] With the development of social industrialization and informationization, the communication, communication and power industries are developing rapidly, and these industries inevitably involve the installation and layout of the most basic cables. The Chinese utility model patent with the authorized announcement number CN203704269U discloses a circular sheath for outlet wires for air conditioners. One end of the round sheath is provided with a ring groove for clamping on the outlet hole on the air conditioner panel, that is, a circular Card slot, one end is provided with an outlet sleeve extending by a certain length. When in use, the cable is worn inside the sheath and connected to the outlet hole through the ring groove. The outlet sleeve protects the cable. This kind of wire When the cable sheath is used in a situation where the external environment ...
