Description

Technical Field

[0001] The utility model relates to the technical field of wire harness assemblies, in particular to a low-voltage wire harness assembly with high temperature resistance. Background Art

[0002] Low-voltage wiring harness assemblies are components used to connect low-voltage cables and devices, usually consisting of multiple wires, insulation materials, sheaths, and connectors. They play a vital role in the power system, transmitting electrical energy from the power source to various electrical devices to ensure the normal operation of the circuit.

[0003] However, although the low-voltage wiring harness assembly has taken heat loss into consideration in the design of the existing technology and adopted corresponding materials and technologies to reduce it, there may still be certain heating problems. Especially under high load, high temperature or adverse environmental conditions, this heat loss will increase, which may affect the overall quality and service life of the wiring harness. Utility Model Content

[0004] The utility model aims to provide a low-voltage wiring harness assembly with high temperature resistance to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A low-voltage wiring harness assembly with high temperature resistance includes a cable, a mounting frame is arranged outside the cable, a heat dissipation component for dissipating heat from the wiring harness is arranged inside the mounting frame, the heat dissipation component includes a cavity arranged inside the mounting frame, a heat dissipation hole and a ventilation hole are arranged on the outer wall of the mounting frame, connecting rods are arranged on the inner walls of the heat dissipation hole and the ventilation hole, one-way plates are arranged at both ends of the connecting rod, a corrugated pipe and a tapered pipe are arranged on the inner wall of the ventilation hole, and a friction layer is arranged on the inner wall of the tapered pipe.

[0007] As a preferred solution of the utility model, the installation frame is distributed at the connection and interface of the wire harness, and the installation frame is sleeved on the outer wall of the cable and locked with the cable by bolts.

[0008] As a preferred solution of the utility model, the cavity is communicated with the heat dissipation hole, the connecting rod is located between the heat dissipation hole and the ventilation hole, and is rotatably connected through a spring shaft, the two ends of the connecting rod extend into the heat dissipation hole and the ventilation hole respectively, and are connected to the one-way plate through bolts.

[0009] As a preferred solution of the utility model, when the temperature of the cable rises, the air in the cavity will expand due to the heat, so that the increased air pressure can push the one-way plate, and the one-way plate can be rotated and opened by rotating the connecting rod. At the same time, the two ends of the connecting rod are linked to open the heat holes and the ventilation holes.

[0010] As a preferred solution of the utility model, both ends of the bellows are respectively connected to the ventilation hole and the tapered tube, the bellows is a wave structure, and the other end of the tapered tube extends into the cavity.

[0011] As a preferred solution of the utility model, the aperture of the tapered tube changes from large to small, which will increase the flow rate of the hot air. The increased flow rate will reduce the pressure, and the reduced pressure will increase the kinetic energy of the hot air. During this kinetic energy conversion process, part of the heat energy will be transferred to the pipe wall, thereby reducing the temperature of the hot air.

[0012] Compared with the prior art, the utility model has the following beneficial effects: in response to the problems raised in the background technology, the present application adopts a heat dissipation component, by installing an isolation frame to wrap the joints and connections that are prone to high temperature during the use of the wiring harness, the external high temperature is isolated when the external ambient temperature is high, and the connection and joints can be protected;

[0013] When the temperature of the wiring harness at the wrapping location is high, the air pressure in the isolation frame will increase, thereby pushing the one-way plate to open for release and allowing the hot air to be discharged for heat dissipation. At the same time, the one-way plate in the ventilation hole can be driven to open through the connecting rod, so that external air is injected into the cavity for ventilation. At the same time, the air consumes the heat in the air when passing through the bellows and the tapered tube, thereby reducing the air temperature. The cooled air can be injected into the cavity to cool the wiring harness.

[0014] The utility model wraps the heat-prone part of the wiring harness, thereby protecting the wiring harness and isolating the wiring harness from the external environment when used in a high-temperature environment. The injected air can be cooled during ventilation, thereby improving the heat dissipation effect of the wiring harness. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1-3 The utility model provides a technical solution: a low-voltage wiring harness assembly with high temperature resistance, including a cable 1, a mounting frame 2 is arranged outside the cable 1, a heat dissipation component for dissipating heat from the wiring harness is arranged inside the mounting frame 2, and the heat dissipation component includes a cavity 3 arranged inside the mounting frame 2. When the temperature of the cable 1 rises, the air in the cavity 3 is heated, thereby increasing the pressure in the cavity 3. The one-way plate 501 in the heat dissipation hole 301 can be pushed open to release the pressure and discharge the hot air in the cavity 3 for heat dissipation. The outer wall of the mounting frame 2 is provided with a heat dissipation hole 301 and a ventilation hole 4. The inner walls of the heat dissipation hole 301 and the ventilation hole 4 are provided with a connecting rod 5 for connecting the heat dissipation hole 301 and the one-way plate 501 in the ventilation hole 4. One-way plate 501, when the one-way plate 501 in the heat dissipation hole 301 is pushed open by pressure, the one-way plate 501 in the ventilation hole 4 is rotated and opened through the connecting rod 5. One-way plates 501 are arranged at both ends of the connecting rod 5. The inner wall of the ventilation hole 4 is arranged with bellows 6 and conical tube 7. External air can be injected into the cavity 3 through the ventilation hole 4. When the air passes through the bellows 6 (due to the irregular shape of the inner part of the pipeline, the hot air will experience different flow paths and speeds to consume the heat of the air to achieve cooling), and after passing through the bellows 6, it is injected into the cavity 3 through the conical tube 7. Since the aperture of the conical tube 7 becomes smaller, the flow rate of the hot air will be accelerated, and the accelerated flow rate will reduce the pressure, and the reduced pressure will increase the kinetic energy of the hot air. During this kinetic energy conversion process, part of the heat energy will be transferred to the pipe wall, thereby reducing the temperature of the hot air. The inner wall of the tapered tube 7 is provided with a friction layer 701, and the friction layer 701 is used to increase the friction of the tapered tube 7, thereby increasing the heat consumption when the air passes through. The mounting frame 2 is installed at the connection and joint of the cable 1. Since the temperature of the connection and joint of the wiring harness will be higher than other parts during the use of the wiring harness, and the contact resistance and current sealing of these two places are higher, it is necessary to focus on this area.

[0022] In this embodiment, all electrical components are controlled by conventional controllers.

[0023] For example, please refer to Figure 1-3The installation frame 2 is distributed at the connection and interface of the wiring harness. The installation frame 2 is sleeved on the outer wall of the cable 1 and locked with the cable 1 by bolts. The cavity 3 is communicated with the heat dissipation hole 301. The connecting rod 5 is located between the heat dissipation hole 301 and the ventilation hole 4 and is rotatably connected by a spring shaft. The two ends of the connecting rod 5 extend into the heat dissipation hole 301 and the ventilation hole 4 respectively, and are connected to the one-way plate 501 by bolts. When the temperature of the cable 1 rises, the air in the cavity 3 will expand due to heat, so that the increase in air pressure can push the one-way plate 501 and rotate through the connecting rod 5. The one-way plate 501 is rotated to open, and at the same time, the two ends of the connecting rod 5 are linked to open the heat dissipation holes 301 and the ventilation holes 4. The two ends of the bellows 6 are respectively connected to the ventilation holes 4 and the tapered tube 7. The bellows 6 is a wave structure, and the other end of the tapered tube 7 extends into the cavity 3. The aperture of the tapered tube 7 changes from large to small, which will increase the flow rate of the hot air. The increased flow rate will reduce the pressure, and the reduced pressure will increase the kinetic energy of the hot air. In this kinetic energy conversion process, part of the heat energy will be transferred to the pipe wall, thereby reducing the temperature of the hot air. When in use, the temperature of the cable 1 rises, which heats the air in the cavity 3, increasing the pressure in the cavity 3, pushing the one-way plate 501 in the heat dissipation hole 301 to open, and the one-way plate 501 in the ventilation hole 4 is opened through the connecting rod 5, so that air enters the cavity 3 through the ventilation hole 4 for ventilation. The air consumes the heat contained in the air after passing through the bellows 6 and the tapered tube 7, thereby cooling the air, thereby achieving heat dissipation for the cable in the cavity 3.

[0024] The working process of the utility model: when in use, the temperature of the cable 1 rises, which heats the air in the cavity 3, increases the pressure in the cavity 3, pushes the one-way plate 501 in the heat dissipation hole 301 to open, and opens the one-way plate 501 in the ventilation hole 4 through the connecting rod 5, so that air enters the cavity 3 through the ventilation hole 4 for ventilation, and the air consumes the heat contained in the air through the corrugated tube 6 and the tapered tube 7, thereby cooling the air and achieving heat dissipation of the cable in the cavity 3. The utility model wraps the heat-prone part of the wire harness, protects the wire harness, isolates it from the external environment when used in a high-temperature environment, and cools the injected air during ventilation, thereby improving the heat dissipation effect of the wire harness.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
