[0004] The purpose of this utility model is to address the following shortcomings in the existing technology: wire harness protective sleeves are mostly consumables, and long-term use can easily cause wear and tear on the surface of the wire harness protective sleeve, affecting the protection effect on the wire harness. In addition, the wire harness protective sleeve and the wire harness are mostly fixedly connected. If the wire harness protective sleeve is damaged, the service life of the wire harness will be reduced accordingly. Therefore, a high-temperature resistant wire harness assembly is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature resistant wire harness assembly includes a wire harness body, on which multiple sets of protective components are sleeved.

[0007] The connecting ring assembly consists of a semi-circular first fixing ring and a semi-circular second fixing ring. One end of the first fixing ring is hinged to one end of the second fixing ring, forming a ring. The contact points of the ends of the first fixing ring away from the hinge and the ends of the second fixing ring away from the hinge are located on the horizontal line of the opening. One end of both the first and second fixing rings is provided with a second wedge groove with the same shape as the first wedge groove. An H-shaped connecting strip is interference-fitted between the first and second wedge grooves.

[0008] Preferably, a plurality of positioning rubber pads are fixedly installed on the inner wall of the protective sleeve, and a plurality of axial heat dissipation grooves are formed on the side of the positioning rubber pads away from the protective sleeve.

[0009] Preferably, the depth of the plurality of axial heat dissipation grooves is 3mm and the spacing is 6mm.

[0010] Preferably, the connecting assembly includes multiple connecting blocks circumferentially and equidistantly fixedly installed on the side of the connecting ring assembly, and multiple locking blocks respectively fixedly installed on the side of the connecting ring assembly. The multiple connecting blocks are all installed on the connecting ring assembly at one end of the protective sleeve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 A high-temperature resistant wire harness assembly includes a wire harness body 1, on which multiple sets of protective components are sleeved. These protective components are interconnected via connecting components. Each protective component includes a protective sleeve 2 and connecting ring kits 3 fixedly installed at both ends of the protective sleeve 2. The protective sleeve 2 is made of silicone rubber and has an opening on its side. T-shaped first wedge grooves 4 are formed on the inner walls of both sides of the opening. The silicone rubber material of the protective sleeve 2 has a certain degree of elasticity and high-temperature resistance, which can improve the overall high-temperature resistance of the wire harness body 1. The multiple sets of protective components are interconnected via connecting components, thereby wrapping the wire harness body 1, protecting the wire harness, and improving the service life of the wire harness.

[0025] The connecting ring assembly 3 consists of a semi-circular first fixing ring 301 and a semi-circular second fixing ring 302. One end of the first fixing ring 301 is hinged to one end of the second fixing ring 302, forming a ring. The contact points between the end of the first fixing ring 301 away from the hinge and the end of the second fixing ring 302 away from the hinge are located on the horizontal line of the opening. One end of both the first fixing ring 301 and the second fixing ring 302 is provided with a second wedge groove 5 that has the same shape as the first wedge groove 4. An H-shaped connecting strip 6 is inserted between the first wedge groove 4 and the second wedge groove 5 with an interference fit.

[0026] The protective sleeve 2 allows the wire harness body 1 to be inserted into the inner ring through the opening, thus enclosing the wire harness body 1 within the protective sleeve 2. At the same time, the first fixing ring 301 and the second fixing ring 302 are closed into a ring, and the opening of the protective sleeve 2 is also closed, aligning the first wedge groove 4 and the second wedge groove 5 on both sides. Then, the two ends of the connecting strip 6 are respectively inserted into the first wedge groove 4 and the second wedge groove 5 on both sides, thereby connecting the first fixing ring 301 and the second fixing ring 302 together, and closing the opening to prevent the protective sleeve 2 from falling off the wire harness body 1.

[0027] When the protective sleeve 2 wears out after prolonged use, disconnect the connection assembly between the two adjacent protective sleeves 2, then pull the connecting strip 6 on the worn protective sleeve 2 out of the first wedge groove 4 and the second wedge groove 5, then rotate the first fixing ring 301 and the second fixing ring 302 to open the opening of the protective sleeve 2, and then take out the wire harness body 1 from the opening, thereby completing the disassembly of the protective sleeve 2 and replacing it with a new protective sleeve 2. This achieves the disassembly and replacement of the worn protective sleeve 2, ensuring the protection effect of the wire harness and improving the service life of the wire harness body 1.

[0028] Multiple positioning rubber pads 7 are fixedly installed on the inner wall of the protective sleeve 2. Multiple axial heat dissipation grooves 8 are opened on the side of the positioning rubber pads 7 away from the protective sleeve 2. The grooves 8 are 3mm deep and 6mm apart. The multiple axial heat dissipation grooves 8 can form an air convection channel to reduce the surface temperature of the wire harness and play a heat dissipation role.

[0029] The connecting assembly includes multiple connecting blocks 9 circumferentially and equidistantly fixed on the side of the connecting ring assembly 3, and multiple locking blocks 13 respectively fixed on one side of the connecting ring assembly 3. The multiple connecting blocks 9 are all installed on the connecting ring assembly 3 at one end of the protective sleeve 2. Multiple slots 10 are circumferentially and equidistantly opened on the connecting ring assembly 3 at the other end of the protective sleeve 2. The side wall of the slot 10 is provided with an arc-shaped slot 11. The side of the connecting ring assembly 3 is provided with an arc-shaped hole 12 that communicates with the arc-shaped slot 11. The locking blocks 13 are interference-fitted into the arc-shaped slot 11, and the connecting blocks 9 are slidably inserted into the arc-shaped hole 12. The number of arc-shaped slots 11 is the same as the number of locking blocks 13, and the distance between every two adjacent arc-shaped slots 11 is the same as the distance between every two adjacent locking blocks 13.

[0030] In two adjacent connecting ring assemblies 3, one connecting ring assembly 3 is equipped with a connecting block 9 and a locking block 13, while the other connecting ring assembly 3 has an arc-shaped locking groove 11, a slot 10, and an arc-shaped hole 12. The locking block 13 is inserted into the arc-shaped locking groove 11, thereby connecting the two adjacent connecting ring assemblies 3 together and connecting the two adjacent protective sleeves 2. When it is necessary to remove the protective sleeve 2, the connecting ring assembly 3 with the locking block 13 is rotated counterclockwise, causing the locking block 13 to move from the arc-shaped locking groove 11 into the slot 10. Move the connector 9 in the direction until the locking block 13 moves into the slot 10. Then, the locking block 13 can be removed from the slot 10, thereby disassembling the two connecting ring kits 3. During installation, insert the locking block 13 on the connecting ring kit 3 into the slot 10, and then rotate the connecting ring kit 3 clockwise to move the locking block 13 towards the arc-shaped slot 11. The connecting block 9 is inserted into the arc-shaped hole 12. The arc-shaped slot 11 can prevent the locking block 13 from detaching from the connecting ring kit 3, thereby completing the installation of the two connecting ring kits 3.

[0031] An anti-slip pad is fixedly bonded to the surface of the card block 13. The anti-slip pad is made of rubber and can increase the friction between the card block 13 and the arc-shaped card groove 11, ensuring the stability of the connection between the two connecting ring kits 3.

[0032] In this invention, when the protective sleeve 2 wears out after prolonged use, the connection between the two adjacent protective sleeves 2 is released, and then the connecting strip 6 on the worn protective sleeve 2 is pulled out from the first wedge groove 4 and the second wedge groove 5. Then, the first fixing ring 301 and the second fixing ring 302 are rotated to open the opening of the protective sleeve 2. Then, the wire harness body 1 is taken out from the opening, thereby completing the disassembly of the protective sleeve 2 and replacing it with a new protective sleeve 2. This achieves the disassembly and replacement of the worn protective sleeve 2, ensuring the protection effect of the wire harness and improving the service life of the wire harness body 1.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
