[0023] The rubber sleeve body 1, the barb 2, the cable 3, the sleeve 4, the flanged sleeve 5, the sleeve body 51, and the flanged ring 52. DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-2 The cable protective rubber sleeve shown comprises an axially penetrating rubber sleeve body 1, barbs 2 and flanged sleeves 5 respectively arranged at the axial ends of the rubber sleeve body 1. The barbs 2 are arranged at the front end of the rubber sleeve body, and the flanged sleeves 5 are arranged at the rear end.

[0026] At least one cable 3 is passed or placed inside the rubber sleeve body 1, and a sleeve 4 is sleeved outside the rubber sleeve body 1; the flanged sleeve 5 and the rubber sleeve body 1 are buckled together at one end of the sleeve 4. The cable protection rubber sleeve isolates the cable and the sleeve 4, and is sleeved at one end of the sleeve 4, preventing the end of the sleeve 4 with burrs and flash from cutting the cable.

[0027] Preferably, the cable protective rubber sleeve is made of silicone. The rubber sleeve body 1, the barb 2, and the flanged sleeve 5 are integrally formed, and the cable protective rubber sleeve is sleeved on the sleeve 4 by the friction between the cable protective rubber sleeve and the sleeve 4. In addition, the silicone material is relatively soft and can better protect the cable. When the surface of the plastic material is smooth, the cable protective rubber sleeve can be installed on the sleeve 4 by interference fit.

[0028] The axial end surface of the rubber sleeve body 1 is provided with an outer chamfer to facilitate the sleeve 4 to be installed.

[0029] The barb 2 protrudes from the outer surface of the rubber sleeve body 1 and is a conical surface. The end of the barb 2 close to the outer chamfer is thinner than the end away from the outer chamfer, that is, it gradually becomes thicker from the front to the back. The outer chamfer is convenient for inserting the sleeve, and the sleeve 4 gradually passes through the barb 2 from the outer chamfer and is then inserted into the rubber sleeve body 1, and the sleeve 4 can squeeze the barb 2; the barb 2 is used to prevent the cable protective rubber sleeve from falling off the sleeve 4.

[0030] Among them, the structure of the flanged sleeve 5 is preferably: the cross-section of the flanged sleeve 5 is an inverted "L" shape as a whole, that is, the edge of the rubber sleeve body 1 is fixed with a 90° bend. It includes a sleeve body 51 that is spaced outside the rubber sleeve body 1, and a flanged ring 52 for connecting the sleeve body 51 and the axial end surface of the rubber sleeve body 1. The flanged ring 52 is perpendicular to the axial direction of the rubber sleeve body 1. The length of the flanged sleeve 5 is shorter than the rubber sleeve body 1, and the interval between the flanged sleeve 5 and the rubber sleeve body 1 is not greater than the wall thickness of the sleeve 4, so that the flanged sleeve 5 can be tightly sleeved on the sleeve 4. When the cable protective rubber sleeve is made of silicone material, the sleeve body 51 is perpendicular to the flanged ring 52.

[0031] The cross-section of the barb 2 is triangular, and the outer chamfer and the side surface of the barb 2 are located on the same inclined plane, so that the outer surface of the cable protective rubber sleeve is a conical surface.

[0032] Specifically, in the radial direction of the cable protective rubber sleeve, the length L of the barb 2 is 3 mm.

[0033] Specifically, the angle of the outer chamfer is 45°.

[0034] Specifically, the cross-sectional shape of the barb 2 is a right triangle, and the outer chamfer and the side surface where the hypotenuse of the barb 2 is located are located on the same inclined plane.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
