Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a combined wire harness. Background Art

[0002] A combined wiring harness refers to a wiring harness composed of multiple independent wires or signal lines. This type of wiring harness can combine cables of different functions and types according to specific application requirements to form an overall wiring harness system.

[0003] According to the publication number CN209472332U, a combined wiring harness includes a lower fixing box and an upper fixing box. An arc-shaped pressing plate is installed in the upper inner cavity of the lower fixing box. The cross section of the arc-shaped pressing plate is set to be semicircular, and the lower end surface of the arc-shaped pressing plate is fixed to the inner wall of the lower fixing box through three vertically welded support rods. The utility model sets an upper and lower combined installation box. On the premise of fixing the wiring harness, a spring is installed at the lower end of the fixed position to cooperate with the upper and lower ear seats, so that the installation is firm and has a certain degree of tension adjustment. By combining the above references, it is found that the existing combined wiring harness has at least the following problems:

[0004] 1. Combined wiring harnesses are usually bound together using binding materials (such as ropes, plastic belts, etc.). The binding method causes the wiring harnesses to squeeze each other, which can easily cause the protective cover of the wiring harness to rupture or break;

[0005] 2. When the wires in the combined wiring harness are bundled together, the free flow of air will be hindered, which may cause heat accumulation and poor heat dissipation, increase the temperature of the equipment, and thus affect its performance and life. Utility Model Content

[0006] The utility model aims to provide a combined wire harness to solve the problems of the combined wire harness in the use process proposed in the above background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A combined wiring harness comprises a wiring harness and a combined loop;

[0009] The combined ring is composed of a penetration ring, a filling layer and a protective layer;

[0010] an air bag, which is arranged inside the penetration ring;

[0011] a trachea connected between the air cells;

[0012] an air nozzle connected to the outer surface of the airbag;

[0013] The heat conducting sheet is arranged inside the protective layer.

[0014] Preferably, the wiring harness is composed of a conductor, an insulating layer, a shielding layer and a protective cover;

[0015] The penetration ring penetrates through the outer surface of the combination ring;

[0016] The protective layer is wrapped around the outer surface of the filling layer.

[0017] Preferably, the conductor is wrapped inside the insulating layer;

[0018] The shielding layer is wrapped around the outer surface of the insulating layer;

[0019] The protective cover is wrapped around the outer surface of the shielding layer.

[0020] Preferably, the heat conductive sheet is provided in multiple groups, and one end of the heat conductive sheet is in contact with the filler of the filling layer, and the other end is in contact with the air.

[0021] Preferably, the material of the filling layer is silicone paste, which has good thermal conductivity and insulation properties and can improve the heat dissipation performance of the wrapped wiring harness.

[0022] Preferably, the airbags and tracheas are provided in multiple groups, and the airbags are connected through the tracheas.

[0023] Preferably, the heat conducting plates are provided in a plurality of groups, and the heat conducting plates are arranged in a circular array with the combination ring as the center.

[0024] The embodiment of the utility model provides a combined wiring harness, which has the following beneficial effects:

[0025] 1. By setting up an airbag, an air tube and an air nozzle, a person connects the inflator to the air nozzle, and the filled gas is transported to the airbag through the air tube. When the airbag is filled with gas, the wiring harness is wrapped. Each wiring harness is wrapped separately and combined with multiple wiring harnesses into an overall wiring harness. Through the use of these structures, the wiring harnesses can be combined and the wiring harnesses are independently fixed, so that the wiring harnesses will not be squeezed against each other, causing cracks or short circuits on the wiring harness surface.

[0026] 2. By setting the filling layer and the thermal conductive sheet, when the wrapped part of the wire harness dissipates heat, the heat of the wire harness is transferred to the filling layer. The material of the filling layer is silicone paste, which can conduct heat to the thermal conductive sheet very well. By contacting with the filling layer, the thermal conductive sheet can absorb heat from the filling layer and quickly transfer it to the surface of the thermal conductive sheet. The thermal conductive sheet transfers the heat to the surrounding air, so that the heat can be dissipated, and then the heat will not accumulate and cause poor heat dissipation, which is convenient for improving the service life and performance of the wire harness.

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example: Figure 1 As shown, a combined wiring harness includes: a wiring harness 1 and a combination ring 2 as the main body of the combined wiring harness, the combination ring 2 is an assembly part for arranging and fixing the wiring harness 1, by bundling the wiring harness 1 together, the wiring harness is kept neat and orderly, by combining multiple wiring harnesses 1 together and fixing them with the combination ring 2, the combination ring 2 provides a stable fixing device to prevent the wiring harness 1 from being loose or messy, the wiring harness 1 is an integral assembly composed of multiple wires or signal lines, and is used for applications such as power transmission, signal transmission or data transmission.

[0035] like Figure 2As shown, it includes: the outer surface of the combination ring 2 is penetrated by a through ring 3, and the inside of the through ring 3 is provided with an air bag 4, and the wire harness 1 passes through the through ring 3 to be fixed by the combination ring 2 and the air bag 4. The air bag 4 can wrap and fix each group of wire harnesses 1 to avoid mutual squeezing between the wire harnesses 1, thereby reducing damage and wear of the wire harnesses 1 and protecting the protective cover 104 of the wire harness 1 from cracking. At the same time, the air bag 4 can also enhance the stability of the combination ring 2 to ensure the fixing effect and overall safety of the wire harness 1. The air bags 4 are connected by air pipes 5, and the combination ring 2 is connected to the air bag 5. The outer surface of the closing ring 2 is penetrated by an air nozzle 6 connected to the airbag 4. A person is connected to the air nozzle 6 through an inflation device, and then the inside of the airbag is filled with gas through an air tube. The inflated airbag 4 wraps the wiring harness 1, so that each group of wiring harnesses 1 in the combination can be fixed by the airbag 4 individually. The airbag 4 can provide better physical support and fixing effect for the combined wiring harness through the coordination of the inflation device, air tube 5 and air nozzle 6, while enhancing stability and safety. This design can better protect the wiring harness 1 and improve the reliability of the use of the wiring harness 1.

[0036] like Figure 3 As shown, it includes: the combination ring 2 is composed of a through ring 3, a filling layer 7 and a protective layer 9. The filling layer 7 is arranged inside the combination ring 2. The filling material of the filling layer 7 is a silicone paste, which has good thermal conductivity and insulation performance, and can improve the heat dissipation effect of the wrapped wire harness. The outer surface of the filling layer 7 is wrapped with a protective layer 9. As the outer sheath of the combination ring 2, the protective layer 9 can provide excellent wear resistance and corrosion resistance for the combination ring 2, and can also provide additional protection for the wrapped wire harness 1 to prevent the influence of the external environment from causing damage or aging of the wire harness 1. A heat conductive sheet 8 is arranged inside the protective layer 9, one end of which is in contact with the material inside the filling layer 7, and the other end is in contact with the air. The heat conductive sheet 8 can quickly conduct the heat transferred to it through contact in the filling layer 7 to the air, thereby playing a role in heat dissipation. This can effectively reduce the temperature of the filling layer 7, and at the same time, it can also promote the balanced distribution of heat between the filling layer 7 and the air, which helps to eliminate the thermal stress caused by uneven temperature and reduce the expansion and contraction caused by temperature differences at the wrapped part of the wiring harness 1, thereby improving the reliability and life of the wiring harness 1.

[0037] like Figure 4As shown, the wiring harness 1 is composed of a conductor 101, an insulating layer 102, a shielding layer 103 and a protective cover 104. The insulating layer 102 is located outside the conductor 101 and serves to isolate the conductor 101 from other parts. It is usually made of insulating materials, such as polyethylene, polyvinyl chloride, etc., which can effectively prevent current leakage and external interference to ensure the safe operation of the circuit. The conductor 101 is arranged inside the insulating layer 102. As the conducting part of the wiring harness 1, the conductor 101 is mainly responsible for the transmission of current and the conduction of signals. It is usually made of metal materials and has good Conductive performance, can stably transmit electrical energy and signals, the outer surface of the insulating layer 102 is wrapped with a shielding layer 103, which can shield and suppress external electromagnetic interference. It is usually made of materials such as metal foil or woven mesh, and can effectively block the interference of external electromagnetic waves to ensure the stability and reliability of the signal. The outer surface of the shielding layer 103 is wrapped with a protective cover 104, which is used to protect the wiring harness 1 from mechanical damage and the influence of the external environment. It is usually made of wear-resistant and corrosion-resistant materials, and can provide additional physical protection to prevent the wiring harness from being damaged by factors such as extrusion, scratching, and chemical erosion.

[0038] Working principle: personnel pass the wiring harness 1 through the through-loop 3, so that multiple wiring harnesses 1 are combined into a group of wiring harnesses 1 under the through-loop 3. Then, personnel connect the inflation device to the air nozzle 6, and the filled gas is transported to the airbag 4 through the air pipe 5. The airbag 4 wraps the wiring harness 1 under the filling of gas. Then, during the operation of the wiring harness 1, when the wrapped part of the wiring harness 1 dissipates heat, the heat of the wiring harness 1 is transferred to the filling layer 7. The material of the filling layer 7 is silicone paste, which can conduct heat to the thermal conductive sheet 8 very well. By contacting with the filling layer 7, the thermal conductive sheet 8 can absorb heat from the filling layer 7 and quickly transfer it to the surface of the thermal conductive sheet 8. The thermal conductive sheet 8 transfers the heat to the surrounding air, so that the heat can be dissipated.
