Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning wiring harness technology, and in particular to a high-voltage resistant automotive air conditioning wiring harness. Background Technology
[0002] High-voltage automotive air conditioning wiring harnesses are used to connect and transmit power and signals in automotive air conditioning systems. Made of high-strength, high-temperature-resistant, and corrosion-resistant materials, they can withstand the high-voltage environment of automotive air conditioning systems, ensuring stable current transmission and normal system operation. These harnesses possess excellent voltage resistance and aging resistance, contributing to improved reliability and safety of the air conditioning system and preventing system failures due to electrical faults. They are widely used in modern automotive air conditioning, refrigeration, and electronic control systems.
[0003] Existing automotive air conditioning wiring harnesses have significant shortcomings, lacking a dedicated channel protection design. When a vehicle is in motion, constant vibrations and bumps cause the wiring harness to rub frequently against the metal parts and hard plastics inside the device, leading to wear and cracking of the wiring harness sheath and potential damage to the internal wires.
[0004] Therefore, this application provides a high-voltage resistant automotive air conditioning wiring harness to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a high-voltage resistant automotive air conditioning wiring harness.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-voltage resistant automotive air conditioning wiring harness, including a supporting shell, and further comprising:
[0007] The damage prevention component includes a fixed base fixed to the bottom of the supporting shell. Each fixed base has a damage prevention ring on its top. Each damage prevention ring has a slot. The damage prevention ring is rotatably mounted on a rotating shaft through the slot. A rotating plate is rotatably mounted on the rotating shaft. A guide wheel is mounted on the rotating plate. A second spring is fixed to the bottom of the guide wheel.
[0008] The positioning component includes a lifting plate disposed on the top of the supporting housing, a positioning plate disposed at the bottom of the lifting plate, a positioning card fixed at the bottom of the positioning card, a positioning plate disposed at the top of the positioning card, and a first spring piece disposed between the positioning plates.
[0009] Furthermore, the guide assembly includes a snap-fit plate fixed to one side of the support housing, a second guide plate slidably disposed between the snap-fit plates, a connecting plate disposed in the middle of the second guide plate, a second handle fixed to one side of the connecting plate, and a guide ring provided in the middle of each of the second guide plates.
[0010] The beneficial effects of adopting the above-mentioned further solution are: the snap-fit plate is fixed to one side of the support shell to provide an installation base, the second guide plate slides between the snap-fit plates, and is connected to the second handle through the connecting plate. Pulling the second handle will drive the connecting plate to slide the second guide plate, adjust the position of the guide ring, and thus flexibly change the direction of the wire harness outlet.
[0011] Furthermore, the other end of the second spring is fixedly connected to the anti-damage ring.
[0012] The beneficial effect of adopting the above-mentioned further solution is that one end of the second spring is connected to the bottom of the guide wheel and the other end is fixed to the anti-damage ring, and the force of the wire harness is buffered by elastic deformation.
[0013] Furthermore, the restraint assembly includes a cable inlet on one side of the supporting housing, a fixing plate fixed to one side of the cable inlet, a first guide plate fixed to both ends of the fixing plate, a sliding groove on the first guide plate, a first handle slidably disposed on the sliding groove, a clamping plate fixed to the middle of the first handle, and a damping spring disposed on the top of the clamping plate, the top of the damping spring being fixedly connected to the fixing plate.
[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the inlet is opened on one side of the supporting shell as the input end of the wire harness. The first guide plate is fixed at both ends of the fixed horizontal plate next to the inlet. The sliding groove on its surface provides a sliding track for the first handle. During operation, the first handle is pushed to move along the sliding groove, which drives the clamping plate fixed in the middle to move synchronously, thereby clamping or releasing the wire harness. The top of the clamping plate is connected to the fixed horizontal plate through a damping spring to form a stable clamping structure and avoid deviation during the clamping process.
[0015] Furthermore, a clamping block is fixed to the side of the support housing away from the damage prevention component.
[0016] The beneficial effects of adopting the above-mentioned further solution are: the clamping block fixed on the side of the supporting shell away from the damage prevention component stabilizes the connecting parts and enhances structural stability.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0018] 1. The mounting base is securely installed at the bottom of the support housing, providing basic support for the entire assembly. The anti-damage ring on the top of the mounting base has a slot, and the rotating shaft is installed on the anti-damage ring through the slot, allowing it to rotate flexibly. The rotating plate on the rotating shaft can adjust its angle with the rotating shaft. The guide wheel above it can contact the wire harness. When the wire harness moves, the guide wheel rotates to reduce friction. At the same time, the second spring at the bottom of the guide wheel is fixed at one end and connected to the anti-damage ring at the other end. When the wire harness is subjected to pressure or shaking, the second spring provides cushioning, reduces impact, and prevents damage to the wire harness, providing all-round protection for the wire harness.
[0019] 2. The lifting plate is located on the top of the supporting shell for easy manual lifting. The positioning plate at the bottom serves as a connector, and the fixed positioning plate at the bottom can hold the wire harness for initial positioning. The first spring between the positioning plates, with its elastic properties, can effectively buffer external vibrations or pressure after the positioning plate fixes the wire harness, preventing the wire harness from being subjected to hard impacts.
