Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a waterproof and high-temperature resistant vehicle light wiring harness, comprising: a wiring harness body 1, an acrylic waterproof layer 101, a JS waterproof coating layer 102, a silica high-temperature resistant layer 103, a mica high-temperature resistant layer 104, an iron tetroxide high-temperature resistant layer 105, a polypropylene reinforced fiber insulation layer 106, a wiring harness core 107, a terminal block 2, a socket 3, a first dustproof plate 4, a first sealing plate 5, a polyurethane waterproof ring 6, a second dustproof plate 7, a sealing ring 8, a second sealing plate 9, a fixing plate 10, and a mounting rod 11. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a terminal 2 is fixedly installed on the right end of the wire harness body 1. A first dustproof plate 4 is slidably connected to the outer side of the front end of the wire harness body 1. A second dustproof plate 7 is slidably installed on the outer side of the rear end of the wire harness body 1. Polyurethane waterproof rings 6 are fixedly connected to the inner left side of the first dustproof plate 4 and the inner left side of the second dustproof plate 7. The first dustproof plate 4 and the second dustproof plate 7 are manually installed on the outer side of the wire harness body 1, so that the first dustproof plate 4 and the second dustproof plate 7 drive the polyurethane waterproof rings 6 and the sealing rings 8 to be installed on the outer side of the wire harness body 1. The first dustproof plate 4 and the second dustproof plate 7 are manually pushed to the right and slid to the right on the outer side of the wire harness body 1, so that the first dustproof plate 4 and the second dustproof plate 7 are slidably installed on the outer side of the left end of the terminal 2. Thus, the first dustproof plate 4 and the second dustproof plate 7 are engaged on the outer side of the left end of the terminal 2 under the sliding action. This causes the first sealing plate 5, which is fixedly installed on the inner side of the first dustproof plate 4 and the inner side of the second dustproof plate 7, to be attached to the outer side of the terminal 2. The mounting rod 11 installed in the middle of the fixing plate 10 is manually tightened. This allows the mounting rod 11 to be threaded into the middle of the fixing plate 10 under the tightening action. The threaded action between the fixing plate 10 and the mounting rod 11 on the upper side of the first dustproof plate 4 causes the mounting rod 11 to move rearward. This movement then allows the mounting rod 11 to be threaded into the middle of the fixing plate 10 on the upper side of the second dustproof plate 7. This facilitates the installation of the first dustproof plate 4 and the second dustproof plate 7 on the outside of the terminal block 2, thus preventing dust from entering through the gap between the wire harness body 1 and the terminal block 2. Inside the terminal 2, a polyurethane waterproof ring 6 is fixedly connected to both the left side of the first dustproof plate 4 and the left side of the second dustproof plate 7. This waterproofing can prevent water from entering the terminal 2 through the gap between the wire harness body 1 and the first dustproof plate 4 and the second dustproof plate 7. The second sealing plate 9, which is set on the rear side of the first dustproof plate 4, is in close contact with the second dustproof plate 7, thus sealing the space between the first dustproof plate 4 and the second dustproof plate 7.

[0029] Specific examples Figure 1 , Figure 2 and Figure 5As shown, sealing rings 8 are fixedly installed on both the inner middle side of the first dustproof plate 4 and the inner middle side of the second dustproof plate 7, and first sealing plates 5 are fixedly installed on both the inner right side of the first dustproof plate 4 and the inner right side of the second dustproof plate 7. The sealing rings 8 and the wire harness body 1 are in close contact, so that the sealing rings 8 seal the gap between the second dustproof plate 7 and the wire harness body 1, and between the first dustproof plate 4 and the wire harness body 1, thereby preventing dust from entering the interior of the first dustproof plate 4 and the second dustproof plate 7, and further preventing dust from passing through the wire harness body. The gap between the wire harness body 1 and the terminal 2 allows dust to enter the interior of the terminal 2. Then, the first sealing plate 5, which is fixedly installed on the inside right side of the first dustproof plate 4 and the inside right side of the second dustproof plate 7, is in close contact with the terminal 2. This allows the first sealing plate 5 to seal the gap between the first dustproof plate 4 and the terminal 2 and the second dustproof plate 7 and the terminal 2, thereby preventing dust from entering the interior of the terminal 2 through the gap. Furthermore, by providing an acrylic waterproof layer 101 and a JS waterproof coating layer 102, the waterproof effect of the wire harness body 1 itself can be improved, thus facilitating waterproofing of the wire harness body 1.

[0030] Specific examples Figure 5 As shown, the silicon dioxide high-temperature resistant layer 103 connected to the inner side of the JS waterproof coating layer 102, the mica high-temperature resistant layer 104 installed inside the silicon dioxide high-temperature resistant layer 103, and the iron oxide high-temperature resistant layer 105 connected to the inner side of the mica high-temperature resistant layer 104, along with the silicon dioxide high-temperature resistant layer 103 installed inside the JS waterproof coating layer 102, have good insulation and high-temperature resistance characteristics, thereby improving the high-temperature resistance of the wire harness body 1. The mica high-temperature resistant layer 104 and the iron oxide high-temperature resistant layer 105 connected inside the silicon dioxide high-temperature resistant layer 103 can further improve the high-temperature resistance of the wire harness body 1. The polypropylene reinforced fiber insulation layer 106 connected to the outer side of the wire harness core 107 can insulate the wire harness core 107, thereby greatly improving the insulation performance of the wire harness body 1. The insertion hole 3 on the right side of the terminal 2 makes it convenient to insert the terminal 2 into the electrode of the car headlight.
