Description

Technical Field

[0001] This utility model belongs to the field of wire harness protection technology, and in particular relates to a wire protection box for protecting high voltage wire harnesses. Background Technology

[0002] High-voltage wiring harnesses play a crucial role in high-voltage power transmission in many fields such as new energy vehicles and power equipment.

[0003] However, existing cable boxes are not secure enough when fixing high-voltage cable harnesses, and the cable harnesses are prone to shaking inside the box, which further increases the risk of cable harness damage. In addition, high-voltage cable harnesses generate heat during the transmission of electrical energy. If the heat cannot be dissipated in time, it will cause the cable harness temperature to be too high, accelerate the aging of the cable harness, and even cause safety problems such as short circuits. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a protective box for high-voltage wire harnesses. By setting a fixing mechanism, the high-voltage wire harness can be limited to prevent displacement, which not only ensures the stability of use, but also avoids resonance caused by collision between the high-voltage wire harness and the box body. The cooling fan can accelerate the air flow speed inside the box and exhaust the hot air inside the box through the exhaust vent, thereby improving the heat dissipation efficiency and ensuring the safety of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A protective box for high-voltage wiring harnesses includes a box body and a fixing mechanism. A cover is movably connected to the upper rear side of the box body. A buckle is fixed to the upper front side of the cover. A slot is formed on the upper front side of the box body, and the buckle engages with the slot. Wiring ports are provided on both the left and right sides of the box body. The fixing mechanism includes a fixing frame, a screw, a clamping plate, and a handle. Fixing frames are fixed to both the front and rear sides of the box body's inner cavity. The fixing frames have a "U"-shaped structure. Two symmetrical screw holes are formed on the adjacent sides of each fixing frame, and a screw is screwed into each of these holes. The inner end of the screw is rotatably connected to a clamping plate via a bearing. The clamping plate has an arc-shaped structure and is located on the same horizontal plane as the wiring port. The screw... Handles are fixed to the outer ends of the box. An air inlet is located on the right side of the box, and an air outlet is located on the left side of the box. The air inlet and air outlet are located above the wiring port. A fan bracket is fixed at the air inlet, and a cooling fan is installed inside the fan bracket. Several heat sinks are fixed at equal intervals on both the front and rear sides of the box. By setting a fixing mechanism, the high-voltage wire harness can be limited to prevent displacement, which not only ensures the stability of use, but also avoids resonance caused by collision between the high-voltage wire harness and the box. The cooling fan can accelerate the air flow speed inside the box and exhaust the hot air inside the box through the air outlet, thereby improving the heat dissipation efficiency. The heat sinks can increase the contact area between the box and the air, and accelerate the dissipation of heat from the box.

[0006] Furthermore, the clamping parts on the inner side of the clamping plate are all equipped with rubber pads to prevent damage to the high-voltage wire harness during fixing.

[0007] Furthermore, the inner wall of the box is provided with a flame-retardant layer, which is an EVA lining, to prevent the box from burning rapidly in the event of a fire, thereby protecting the safety of the high-voltage wiring harness.

[0008] Furthermore, dust filters can be detachably installed at both the air inlet and the air outlet. The dust filters can effectively block dust from entering the housing. When a lot of dust adheres to the surface of the dust filters, they can be removed from the air inlet or the air outlet for cleaning or replacement to ensure unobstructed heat dissipation.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a fixing mechanism, the high-voltage wire harness can be limited to prevent displacement, which not only ensures the stability of use, but also avoids resonance caused by collision between the high-voltage wire harness and the box; the cooling fan can accelerate the air flow speed inside the box and exhaust the hot air inside the box through the exhaust port, thereby improving the heat dissipation efficiency; the heat sink can increase the contact area between the box and the air, and accelerate the dissipation of heat from the box.

[0010] 2. Rubber pads are provided on the clamping parts inside the clamping plates to prevent damage to the high-voltage wire harness during fixing. The inner wall of the box is provided with a flame-retardant layer, which is an EVA lining. This layer can prevent the box from burning rapidly in the event of a fire, thereby protecting the safety of the high-voltage wire harness. Dust screens can be detachably installed at the air inlet and exhaust outlet. The dust screens can effectively block dust from entering the box. When a lot of dust adheres to the surface of the dust screen, it can be removed from the air inlet or exhaust outlet for cleaning or replacement to ensure unobstructed heat dissipation.

[0017] See appendix Figure 1-3As shown, a protective box for high-voltage wire harnesses includes a box body 1 and a fixing mechanism 9. A cover 2 is movably connected to the upper side of the rear end of the box body 1. A buckle 3 is fixed to the front of the upper end of the cover 2. A slot 4 is opened on the upper front end of the box body 1, and the buckle 3 is engaged with the slot 4. Wiring ports 5 are opened on both the left and right sides of the box body 1. The fixing mechanism 9 includes a fixing frame 91, a screw 92, a clamping plate 93, and a handle 94. The fixing frame 91 is fixed on both the front and rear sides of the inner cavity of the box body 1. The fixing frame 91 has a "U" shaped structure. Two symmetrical screw holes are opened on the side of the fixing frame 91 that are close to each other. A screw 92 is screwed into each of the screw holes. The inner end of the screw 92 is rotatably connected to the clamping plate 93 through a bearing. The clamping plate 93 has an arc-shaped structure. The clamping plate 93 and the wiring port 5 are located on the same horizontal plane. Handles 94 are fixed to the outer ends of the boxes 2. An air inlet 6 is provided on the right side of the box 1 and an exhaust outlet 8 is provided on the left side of the box 1. The air inlet 6 and the exhaust outlet 8 are located above the wiring port 5. A fan bracket 7 is fixed at the air inlet 6, and a cooling fan 14 is installed inside the fan bracket 7. Several heat sinks 12 are fixed at equal intervals on the front and rear sides of the box 1. By setting a fixing mechanism 9, the high-voltage wire harness can be limited to prevent it from shifting, which not only ensures the stability of use, but also avoids the high-voltage wire harness from colliding with the box 1 and causing resonance. The cooling fan 14 can accelerate the air flow speed inside the box 1 and exhaust the hot air inside the box 1 through the exhaust outlet 8, thereby improving the heat dissipation efficiency. The heat sinks 12 can increase the contact area between the box 1 and the air, and accelerate the dissipation of heat from the box 1.

[0018] Rubber pads 10 are provided on the clamping parts inside the clamping plate 93 to prevent damage to the high-voltage wire harness during fixing.

[0019] The inner wall of the box 1 is provided with a flame-retardant layer 11, which is an EVA lining. This layer can prevent the box 1 from burning rapidly in the event of a fire, thereby protecting the safety of the high-voltage wiring harness.

[0020] Dust filters 13 can be detachably installed at both the air inlet 6 and the air outlet 8. The dust filters 13 can effectively block dust from entering the box. When a lot of dust adheres to the surface of the dust filters 13, they can be removed from the air inlet 6 or the air outlet 8 for cleaning or replacement to ensure unobstructed heat dissipation.

[0021] Working principle: The high-voltage wire harness is inserted into the box 1 through the wiring ports 5 on the left and right sides of the box 1. Then, the handle 94 in the fixing mechanism 9 is rotated, which drives the screw 92 to rotate. Since the screw 92 is screwed into the screw hole on the fixing bracket 91, the screw 92 moves inward when it rotates, which in turn drives the clamping plate 93 to move inward through the bearing. The clamping plate 93 has an arc-shaped structure, which can adapt to the shape of the high-voltage wire harness and clamp it, thereby stably fixing the high-voltage wire harness in the box 1 and preventing it from shaking. This not only ensures the stability of use, but also avoids the resonance phenomenon caused by the high-voltage wire harness colliding with the box 1. When the high-voltage wire harness generates heat during operation, the cooling fan 14 at the air inlet 6 on the right side of the box 1 starts, drawing outside air into the box 1. The air flows inside the box 1. The heat exchangers exchange heat with the high-voltage wiring harness, and the air carrying the heat is then discharged from the exhaust port 8 on the left side of the box 1 to achieve heat dissipation. The heat sink 12 can increase the contact area between the box 1 and the air, and accelerate the dissipation of heat from the box 1. The clamping parts on the inner side of the clamping plate 93 are equipped with rubber pads 10 to avoid damage to the high-voltage wiring harness during fixing. The inner wall of the box 1 is provided with a flame-retardant layer 11, which is an EVA lining, which can prevent the box 1 from burning rapidly in the event of a fire, thereby protecting the safety of the high-voltage wiring harness. Dustproof nets 13 can be detachably installed at the air inlet 6 and the exhaust port 8. The dustproof nets 13 can effectively block dust from entering the box. When a lot of dust adheres to the surface of the dustproof nets 13, they can be removed from the air inlet 6 or the exhaust port 8 for cleaning or replacement to ensure unobstructed heat dissipation.
