[0019] Below with reference to the embodiment and the attached Figures 1 to 4 , the technical solution of the utility model is further elaborated.
[0020] Example 1
[0021] A high-voltage wire harness fixing bracket device includes: a rubber wire sleeve 1 and a metal bracket 2, the rubber wire sleeve 1 is internally provided with through holes 11 for accommodating the wire harness, the through holes 11 are connected to each other and the outermost through holes 11 are connected to the outside, the outside of the rubber wire sleeve 1 is provided with an annular groove 12 perpendicular to the wire harness direction, the rubber wire sleeve 1 is provided with tie grooves 13 at the front and rear, the metal bracket 2 includes a U-shaped portion 21 and a connecting portion 22, the left end of the connecting portion 22 is connected to the right end of the U-shaped portion 21, the right end of the connecting portion 22 is provided with a threaded hole 23, and the U-shaped portion 21 is clamped to the lower side of the annular groove 12.
[0022] like Figures 1 to 4 As shown, the usage principle of the present invention is: first, pull open the rubber wire sleeve 1 and insert the wire harness into the through hole 11. The soft properties of the rubber wire sleeve 1 ensure that the wire harness will not be squeezed and damaged. Then, insert the U-shaped part 21 of the metal bracket 2 into the annular groove 12 on the outside of the rubber wire sleeve 1. Finally, put the cable tie on and fix it on the cable tie groove 13 to achieve a detachable and fixed connection between the rubber wire sleeve 1 and the metal bracket 2 without falling off. Then, fix the connecting part 22 of the metal bracket 2 to the vehicle body.
[0023] The shape of the metal bracket formed by the U-shaped portion 21 and the connecting portion 22 is suitable for the layout structure of the vehicle body. Together with the internally clamped rubber wire sleeve, it solves the problem of interference between the fixation of the high-voltage wire harness and the vehicle body, effectively protecting the high-voltage wire harness from wear and tear. The structure is strong and reliable. At the same time, when the vehicle body vibrates, the rubber wire sleeve 1 can effectively absorb the vibration of the vehicle body, thereby protecting the cable; the rubber wire sleeve is clamped to the left side of the metal bracket, and the metal bracket also has a protective and fixing effect on the rubber wire sleeve, and is easy to install; the metal bracket is fixed to the vehicle body with bolts and is not easy to break; the rubber wire sleeve adopts 2-hole wire passing, and the universal design can be installed and used in a variety of wire harness fixes.
