[0002] There are a large number of conductive wires distributed inside the car. In order to ensure that the conductive wires are not worn during use, they are usually wrapped in rubber protective covers. However, existing wiring harness protective covers are often unable to fix the electronic wiring harness in the wiring harness protective covers.

[0003] Existing patent CN 212380876 U3 is a fireproof electronic wire harness protective cover. One end of the electronic wire harness is sequentially passed through the through hole on the left fixing seat, the inside of the protective cover body and the through hole on the right fixing seat, so that the electronic wire harness is located in front of the corresponding upper arc clamping plate and lower arc clamping plate. Under the elastic force of the first spring and the second spring, the upper arc clamping plate and the lower arc clamping plate can be used to clamp and fix the electronic wire harness, and the insulating pad is used to contact the electronic wire harness to protect the electronic wire harness, and the protective cover body is used to isolate and protect the electronic wire harness.

[0004] However, in the process of using the existing patented electronic wiring harness protective cover with fire-proof performance, the distance between the two arc-shaped clamps needs to be smaller than the diameter of the wiring harness before the spring undergoes elastic deformation in order to fix the wiring harness. This results in the need for manual opening of the two arc-shaped clamps when the wiring harness passes through the fixing seat, making the installation of the wiring harness more inconvenient. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides a high-temperature and corrosion-resistant wire harness protective cover, including a protective cover body, a first mounting seat and a second mounting seat, the protective cover body is provided with a ceramic fiber layer, the first mounting seat is fixedly mounted on the protective cover body, the second mounting seat is fixedly mounted on the protective cover body and is located at one end of the protective cover body away from the first mounting seat, and also includes a fixing device, the fixing device includes a connecting rod, a spring, a fixed arc plate and a connecting assembly, the connecting rod is rotatably mounted in the first mounting seat through the connecting assembly, the spring is fixedly mounted in the first mounting seat, one end of the spring is fixedly connected to the connecting rod, and the fixed arc plate is fixedly mounted on the connecting rod.

[0007] Wherein, the connecting assembly includes a fixing rod and a pin, the fixing rod is fixedly installed in the first mounting seat, and the fixing rod is rotatably connected to the connecting rod through the pin.

[0008] Wherein, the fixed arc plate further comprises an insulating layer, and the insulating layer is fixedly mounted on a side of the fixed arc plate away from the connecting rod.

[0010] Wherein, the second mounting seat further includes a limiting rod, and the limiting rod is fixedly installed in the second mounting seat.

[0011] The utility model discloses a high-temperature and corrosion-resistant wire harness protective cover. When in use, the wire harness is passed through the first mounting seat, the protective cover body and the second mounting seat in sequence. When the wire harness contacts the connecting rod in the first mounting seat, the wire harness pushes the connecting rods on the upper and lower sides to rotate in opposite directions around the fixing rod. At this time, the upper and lower groups of springs begin to compress respectively, and the reverse rotation of the connecting rods opens the gap between the connecting rods, so that the wire harness can pass through the first mounting seat smoothly. After the wire harness passes through the first mounting seat, the spring drives the connecting rod to reset under the action of its own elastic force, and the connecting rod also drives the fixed arc plate to abut against the wire harness, and the wire harness is fixed under the joint cooperation of the upper and lower groups of fixed arc plates, so that the wire harness can be quickly passed through the first mounting seat through the adaptive adjustment of the connecting rod.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a high temperature and corrosion resistant wire harness protective cover according to the first embodiment of the utility model. Figure 2 It is a connection schematic diagram of the connecting rod and the fixing rod of the first embodiment of the utility model.

The above-mentioned scheme solves the above-mentioned problem that before the spring undergoes elastic deformation, the distance between the two arc-shaped clamping plates needs to be smaller than the diameter of the wire harness in order to fix the wire harness, which results in the need for manual opening of the two arc-shaped clamping plates when the wire harness passes through the fixing seat, thereby making the installation of the wire harness inconvenient. It can be understood that the present scheme can also be used to solve the problem of preventing the wire harness from being worn out in the protective cover body.

[0021] In this embodiment, after the upper and lower groups of connecting rods 105 come into contact with the wire harness, they rotate in the opposite direction with the cooperation of the connecting assembly, so that the gap between the connecting rods 105 is opened, thereby facilitating the wire harness to pass through the first mounting seat 102 .

[0022] Among them, the connecting rod 105 is rotatably installed in the first mounting seat 102 through the connecting assembly, the spring 106 is fixedly installed in the first mounting seat 102, one end of the spring 106 is fixedly connected to the connecting rod 105, the fixed arc plate 107 is fixedly installed on the connecting rod 105, the protective cover body 101 is made of rubber material, the first mounting seat 102 and the second mounting seat 103 have the same structure, and are respectively welded to the two ends of the protective cover body 101, the ceramic fiber layer 104 is located on the outer layer of the protective cover body 101, the ceramic fiber layer 104 has the advantages of light bulk density, high temperature resistance, low heat conduction efficiency, good thermal insulation performance, etc., through the setting of the ceramic fiber layer 104, the protective cover body 101 has the performance of high temperature resistance and corrosion resistance, the number of the fixing device is two groups, and they are symmetrically distributed on the first mounting seat 1 02, the connecting rod 105 is tiltedly arranged in the first mounting seat 102 on the upper and lower sides of the interior, the spring 106 is located between the connecting rod 105 and the inner wall of the first mounting seat 102, the fixed arc plate 107 is an arc-shaped structure, and the fixed arc plate 107 is fused to the connecting rod 105. When the wiring harness enters the first mounting seat 102 and contacts the connecting rod 105, the upper and lower groups of the connecting rods 105 start to rotate in the opposite direction with the cooperation of the connecting assembly, so that the spring 106 is compressed and the gap between the connecting rods 105 is opened, so that the wiring harness can pass through the first mounting seat 102 smoothly, and then the spring 106 drives the fixed arc plate 107 to fix the wiring harness through the connecting rod 105 under the action of its own elastic force, so that the wiring harness can quickly pass through the first mounting seat 102 through the adaptive adjustment of the connecting rod 105.

[0023] Secondly, the fixing rod 108 is fixedly installed in the first mounting seat 102, and the fixing rod 108 is rotatably connected to the connecting rod 105 through the pin 109.
