Description

Technical Field

[0001] The present application relates to the technical field of cable harnesses, and in particular to a charging harness and a production process. Background Art

[0002] Cable harnesses are mainly used to transmit power and signals. Some composite cables also have conductors and optical fibers, which can transmit both power and optical signals.

[0003] The cable harness itself will generate a lot of heat during use, and the greater the current passing through the cable, the more heat is generated. Especially when the cable harness is used for charging a car, the current passing through the cable harness is large, and the heat dissipation speed of the cable itself is slow. Therefore, for safety reasons, the current passing through the cable harness can only be limited. If the current is increased, the safety risk of the cable harness will increase. Summary of the invention

[0004] In order to increase the current passing through the cable harness and reduce the safety risk during the operation of the cable harness, the present application provides a charging harness and a production process.

[0005] In the first aspect, the present application provides a charging harness, which adopts the following technical solution: A charging harness comprises an insulating layer, a conductor in the insulating layer, a filler and a cooling tube, wherein a cooling medium is stored in the cooling tube or passed into the cooling tube in real time, and the filler is made of PE, PP or Teflon.

[0006] By adopting the above technical solution, the cooling medium is stored or introduced in real time in the cooling pipe, and the filling piece is made of PE, PP or Teflon filling materials with good heat dissipation effect. The filling piece and the cooling medium cooperate to achieve heat dissipation of the conductor, thereby greatly improving the heat dissipation effect of the wiring harness, thereby increasing the current passing through the wiring harness and reducing the safety risk during the operation of the cable harness.

[0007] Optionally, a support member made of a metal material is provided on the outer side walls of the cooling tube and the conductor, and the support member is used to support the cooling tube and conduct the heat generated by the conductor to the cooling medium in the cooling tube.

[0008] By adopting the above technical solution, the cooling tube and the conductor are generally made of soft materials, which leads to poor strength of the cooling tube and the conductor. The cooling tube is easily deformed when the cable harness is subjected to extrusion and tensile forces, thereby reducing the heat dissipation effect of the harness through the cooling tube, reducing the current passing through the harness, and increasing the safety risk of the harness during operation. Moreover, the deformation of the conductor will further increase the safety risk of the harness during operation.

[0009] The cooling tubes and conductors are supported by metal supports, thereby reducing the probability of deformation of the cooling tubes and conductors when subjected to external pressure and tensile force. When the wiring harness is subjected to extrusion and tensile force, the support members can disperse the force, reducing the risk of deformation of the cooling tubes and conductors. Furthermore, the metal supports can further improve the heat dissipation effect of the wiring harness, increase the current passing through the wiring harness, and reduce the safety risk during the operation of the wiring harness.

[0010] Optionally, the support member is a metal wire spirally wound on the outer wall of the cooling tube or the conductor, the metal wire forms a plurality of spiral connecting segments that abut against each other, and two adjacent connecting segments form an annular positioning cavity and a filling cavity respectively close to the cooling tube and the side of the filling member. The metal wire presses against the cooling tube and forms a plurality of positioning portions on the cooling tube that are squeezed into the positioning cavity and fit with the plurality of connecting segments. When the filling member is filled, it enters the filling cavity to form a filling portion.

[0011] By adopting the above technical scheme, the support member is formed by winding the metal wire, which makes the manufacturing process relatively simple. At the same time, multiple spiral connecting segments squeeze the cooling tube, so that the cooling tube is slightly deformed to form a positioning portion entering the positioning cavity, so that the metal wire can be connected to the cooling tube as a whole, and the filling member enters the filling cavity to form a filling portion, that is, the filling member, the insulating layer and the support member are connected as a whole, so as to jointly support the tension and pressure forces exerted on the wire harness, thereby greatly improving the stability of the wire harness during operation, further increasing the current passing through the wire harness and reducing the safety risks during operation of the wire harness.

[0012] At the same time, the metal wire has a certain elasticity. When the wire harness is bent and twisted, multiple connecting segments can be buffered under the action of elastic force, reducing the resistance of the metal tube when the wire harness is bent and twisted, reducing the adverse effects on the normal function of the wire harness, and at the same time increasing the current passing through the wire harness and reducing the safety risks during the operation of the wire harness.

[0013] Optionally, the two supports on the cooling tube and the conductor abut against each other and the connecting section on one of the supports extends into the filling cavity on the other support.

[0014] By adopting the above technical solution, the support member can also support the conductor, and the support member can further accelerate the heat dissipation generated by the conductor to achieve heat dissipation. At the same time, the support members located on the cooling tube and the conductor abut against each other, thereby further improving the support and dispersion effect of the force, and accelerating the heat dissipation effect of the wiring harness, further increasing the current passing through the wiring harness and reducing the safety risks during the operation of the wiring harness.

[0015] Optionally, it also includes a secondary pipe body for storing or introducing a cooling medium in real time, wherein at least two secondary pipe bodies are provided and are located on both sides of the cooling pipe and are used to occupy the gap space between the cooling pipe and the conductor.

[0016] By adopting the above technical solution, the gap between the cooling tube and the conductor is occupied by the auxiliary tube body, thereby increasing the volume of the cooling medium passing through the wiring harness of the same size, allowing more cooling medium to dissipate heat for the wiring harness, further increasing the current passing through the wiring harness and reducing the safety risks during the operation of the wiring harness.

[0017] In the second aspect, the present application provides a production process, which adopts the following technical solution: A production process comprises the following steps: Production of support parts: multiple support parts are produced through a screw mechanism; Installing support members: installing multiple support members on the outer side walls of the cooling tube and the conductor through a mounting mechanism; Extruded filler: The filler material is coated on the conductor, cooling tube, and support member and the gap is filled to form a filler; Extruded insulation layer: The insulation layer is formed by extrusion and the filler is wrapped.

[0018] By adopting the above technical solution, since the support member is formed by winding the metal wire around the outside of the cooling tube and the conductor, it is necessary to rotate the metal wire or the cooling tube and the conductor during the production of the support member. However, the lengths of the above three products are relatively long, which makes it easy for the three products to twist or even entangle during the production process, thereby reducing the quality and production efficiency of the wire harness.

[0019] The support piece is produced by a spiral mechanism, and then the support piece is fixedly mounted on the outer wall of the cooling tube and the conductor by an installation mechanism. The filling material is then coated on the conductor, the cooling tube and the support piece to form a filling piece, and finally an insulating layer is formed by extrusion. The insulating layer coats the filling piece, thereby realizing the production of the wiring harness. Through the production of a single structure, the interference caused by the simultaneous production of two structures is reduced, making the production process safe and stable, thereby improving the quality and production efficiency of the wiring harness, thereby increasing the current of the wiring harness and reducing the safety risks during the operation of the wiring harness.

[0020] Optionally, the mounting mechanism includes: Two rotating boxes, the bottom of which is rotatably arranged on the machine body and moves closer to or away from each other; Multiple sets of rotating wheels, rotatably mounted on two rotating boxes; A driving member, used for driving the rotating wheel to rotate and for driving the cooling tube or the conductor to move; Two clamping plates are rotatably arranged in two rotating boxes, the two rotating boxes are close to each other so that the two clamping plates are close to the clamping support and the support is located in the rotating box; or the two rotating boxes are far away from each other and are convenient for placing the support; A driving assembly, used for driving the two rotating boxes and the two clamping plates to rotate; The heating component is used for heating the support member and making the support member expand.

[0021] By adopting the above technical solution, the driving component starts to drive the two rotating boxes away from each other, and then the support member can be placed in, the driving component starts to drive the two rotating boxes to abut against each other, and the two clamping plates clamp and position the support member, the driving member drives multiple rotating wheels to rotate, and the rotating wheels drive the cooling pipe to move, and at the same time the driving component drives the two clamping plates and the support member to rotate, so that the support member can be sleeved on the cooling pipe, and the cooling pipe enters the positioning cavity after being squeezed and deformed, and at the same time the heating component heats and expands the support member, so that the inner diameter of the support member becomes larger due to the expansion, making it easier for the cooling pipe to pass through the support member, and when the support member is sleeved on the cooling pipe, the heating component stops heating, so that the support member cools and shrinks, increasing the volume of the cooling pipe entering the positioning cavity, thereby making the installation process more convenient and stable, thereby improving the quality and production efficiency of the wiring harness, thereby increasing the current of the wiring harness and reducing the safety risks during the operation of the wiring harness.

[0022] Optionally, the driving component includes: Rotating member 1, used for driving two rotating boxes to rotate; Two arc-shaped racks are respectively arranged on two clamping plates The second rotating member is arranged on the outer side wall of the rotating box; The gear is arranged on the second output shaft of the rotating member and meshes with the arc-shaped rack.

[0023] By adopting the above technical solution, the rotating member 1 drives the two rotating boxes and the two clamping plates to rotate, so that the two rotating boxes are opened and the two clamping plates are away from each other, and then the support member is placed in the two rotating boxes. The rotating member 1 drives the two rotating boxes to rotate, so that the two rotating boxes are abutted against each other and the support member is located in the two rotating boxes. At the same time, the two clamping plates are clamped on the support member for positioning, and then the rotating member 2 drives the two clamping plates and the support member to rotate, so that the support member is easier to be mounted and fixed on the cooling pipe or conductor.

[0024] After the installation is completed, the cooling pipe is moved out of the rotating box, the rotating part 2 stops rotating, and the rotating part 1 starts to drive the two rotating boxes away from each other, and then the supporting parts can be put in for production, thereby improving the stability and convenience of the production process, and improving the quality and production efficiency of the wire harness.

[0025] Optionally, the heating component includes: A heating wire is arranged in the rotating box and is used to heat the support member; Temperature detector, used to detect the temperature inside the rotating box.

[0026] By adopting the above technical solution, the heating wire is used to heat and expand the support member, and the temperature detector controls the temperature in the rotating box, so that the support member can be heated while reducing the consumption of heat energy.

[0027] Optionally, a cold air duct for blowing air to cool the support member is provided on one end of the rotating box away from the cooling pipe and entering the rotating box.

[0028] By adopting the above technical solution, after all the support parts are put on the cooling pipe, the heating component stops heating, and the air cooling pipe starts to blow air to cool the support parts, so that the support parts cool down and shrink quickly, increasing the squeezing force of the support parts on the cooling pipe, improving the stability between the two, and improving the quality and production efficiency of the wire harness.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. By storing or introducing cooling medium in the cooling pipe in real time, and using PE, PP or Teflon filling materials with good heat dissipation effect as the filler, the filler and the cooling medium cooperate to dissipate heat from the conductor, thereby greatly improving the heat dissipation effect of the wiring harness, thereby increasing the current passing through the wiring harness and reducing the safety risk during the operation of the cable harness.

Furthermore, the metal support can further improve the heat dissipation effect of the wiring harness, increase the current passing through the wiring harness, and reduce the safety risk during the operation of the wiring harness.

DETAILED DESCRIPTION

[0033] The present application is described in further detail below.

[0034] An embodiment of the present application discloses a charging harness.

[0035] Embodiment 1 Reference Figure 1 The charging harness includes an insulating layer 11, a conductor 12 located in the insulating layer 11, a filler 13 and a cooling tube 14. The cooling tubes 14 and the conductors 12 are arranged at intervals and arranged in a circular array around the axis of the insulating layer 11. Each cooling tube 14 is located between two conductors 12. The cooling tube 14 can store or introduce a cooling medium in real time from the outside. At the same time, the material of the filler 13 is PE, PP or Teflon. PE is polyethylene, PP is polypropylene, and Teflon is polytetrafluoroethylene. PE, PP or Teflon all have good thermal conductivity and heat dissipation effects, so that the cooling medium and the filler 13 material work together to achieve heat dissipation of the harness.

[0036] The working principle of the embodiment of the present application is as follows: The cooling medium can cool and dissipate the heat of the cable harness, while the PE, PP or Teflon material can dissipate the heat generated at the conductor 12 for heat dissipation, thereby increasing the current passing through the cable harness and reducing the safety risk during the operation of the cable harness.

[0037] Embodiment 2 Reference Figure 2 and Figure 3The difference between this embodiment and embodiment 1 is that a support member 2 made of metal material is provided on the outer wall of the cooling tube 14 and the conductor 12. The support member 2 can be used to support the cooling tube 14 and the conductor 12, and enable the heat generated by the conductor 12 to be more quickly transferred to the cooling medium in the cooling tube 14 for heat dissipation. It also includes four sub-tube bodies 26 located in the insulating layer 11, each sub-tube body 26 is located between adjacent cooling tubes 14 and conductors 12, and the diameter of the sub-tube body 26 is smaller than the diameter of the cooling tube 14. The sub-tube body 26 occupies the gap space between the cooling tube 14 and the conductor 12. The cooling medium can be stored in the sub-tube body 26 or introduced into it in real time from the outside. The following is explained by taking the support member 2 located on the conductor 12 as an example.

[0038] Reference Figure 3 and Figure 4 The support member 2 is a metal wire spirally wound on the outer wall of the conductor 12 and abutting against each other. The metal wire is preferably made of copper, aluminum, etc. The metal wire forms a plurality of spiral connecting segments 21 abutting against each other. An annular positioning cavity 22 is formed between two adjacent connecting segments 21 and located close to the conductor 12. At the same time, an annular filling cavity 23 is formed between the two connecting segments 21 and located close to the filling member 13.

[0039] After the metal wire is pressed against the cooling tube 14, a certain extrusion pressure is formed on the conductor 12. The extrusion pressure causes the conductor 12 to be squeezed and deformed to form a positioning portion 24 that enters the positioning cavity 22. At the same time, the filling piece 13 enters the filling cavity 23 to form a ring-shaped filling portion 25 when filling. The positioning portion 24 and the filling portion 25 connect the support member 2 with the cooling tube 14, the conductor 12 and the filling member 13 as a whole. When the wiring harness is subjected to extrusion or tension and other forces, the support member 2 can disperse the forces, which greatly reduces the risk of deformation and damage of the cooling tube 14, the conductor 12 and the filling member 13, and improves the stability of the wiring harness during operation.

[0040] The two supports 2 located on the cooling tube 14 and the conductor 12 and on the two conductors 12 are positioned against each other, that is, the connecting section 21 located on one of the supports 2 extends into the filling cavity 23 located on the other support 2 and is positioned against each other, so that the heat generated at the conductor 12 can be conducted to the cooling tube 14 more quickly. Furthermore, the support 2 can also reduce the risk of deformation of the cooling tube 14, thereby greatly improving the cooling and heat dissipation effect of the wiring harness, increasing the current passing through the wiring harness and reducing the safety risk during the operation of the wiring harness.

[0041] The working principle of the embodiment of the present application is as follows: The support member 2 can support the cooling tube 14 and the conductor 12, and the support member 2 can connect the cooling tube 14, the conductor 12 and the filling member 13 to each other, so that the support member 2 disperses the force, thereby improving the stability of the wiring harness during operation. At the same time, the support member 2 can more quickly conduct the heat generated by the conductor 12 to the cooling tube 14 for cooling and heat dissipation, thereby greatly improving the cooling and heat dissipation effect of the wiring harness, further increasing the current passing through the cable harness and reducing the safety risks during the operation of the cable harness.

[0042] The embodiment of the present application discloses a production process.

[0043] Reference Figure 2 , Figure 5 and Figure 6 , the production process comprises the following steps: Producing the support members 2: A plurality of support members 2 are produced by a spiral mechanism. The spiral mechanism can adopt existing spring production equipment or other equipment to produce the support members 2.

[0044] Installing the support members 2: installing the plurality of support members 2 onto the outer side walls of the cooling tube 14 and the conductor 12 through the installation mechanism 3; Extruded filling member 13: The filling member 13 is formed by coating the filling material on the conductor 12, the cooling tube 14, and the support member 2 and filling the gap; Extruded insulating layer 11: The insulating layer 11 is formed by extrusion and the filler 13 is covered.

[0045] The installation process of the cooling tube 14 is the same as that of the conductor 12, and the cooling tube 14 is used as an example for explanation below; the installation mechanism 3 includes two rotating boxes 31, multiple sets of rotating wheels 32, a driving member 33, two clamping plates 34, a driving component 4 and a heating component 5, the bottom of the two rotating boxes 31 are rotatably installed on the body 15, and the body 15 is supported on the ground. The length direction of the two rotating boxes 31 is parallel to the length direction of the body 15 and one end is close to each other and is in an open state. The two rotating boxes 31 can be opened by moving away from each other, or the two rotating boxes 31 can be positioned against each other by approaching each other. Both ends of the two rotating boxes 31 are provided with through holes 35 for the cooling tube 14 and the support member 2 to pass through.

[0046] A plurality of groups of rotating wheels 32 are arranged at intervals along the length direction of the rotating box 31 and are distributed at both ends of the rotating box 31 and inside the rotating box 31. A plurality of rotating wheels 32 are arranged in a circular array around the axis of the through hole 35 for each group of rotating wheels. A plurality of driving members 33 are provided and are arranged one-to-one corresponding to the plurality of groups of rotating wheels 32. The driving member 33 is a motor. The driving member 33 is fixedly mounted on the side wall of the rotating box 31 and is used to drive the rotating wheel 32 to rotate. The driving member 33 drives the rotating wheel 32 to rotate, and the plurality of rotating wheels 32 located at the entrance end of the cooling pipe 14 press against the cooling pipe 14, and the plurality of rotating wheels 32 located at the output end of the cooling pipe 14 press against the support member 2 for positioning, thereby driving the cooling pipe 14 to enter or output.

[0047] The two clamping plates 34 are semicircular and rotatably arranged in the two rotating boxes 31. At the same time, the two clamping plates 34 can be rotated from one rotating box 31 to the other rotating box 31. The axis between the clamping plates 34 and the through holes 35 coincides. After the two rotating boxes 31 move away from each other, the support 2 can be placed between the two clamping plates 34 and located in the rotating boxes 31. After the two rotating boxes 31 approach each other, the two clamping plates 34 can be close to each other and abut against each other, so as to achieve clamping and positioning of the support 2. At the same time, the two clamping plates 34 are arranged corresponding to the support 2, and the number of clamping plates 34 increases accordingly as the number of support 2 increases.

[0048] The driving assembly 4 is used to drive the two rotating boxes 31 and the two clamping plates 34 to rotate. The driving assembly 4 includes a rotating part 1, two arc-shaped racks 42, a rotating part 2 43 and a gear 44. The rotating part 1 is a cylinder or an electric push rod. The rotating part 1 is rotatably installed on the two rotating boxes 31 and is used to drive the two rotating boxes 31 to rotate; the two arc-shaped racks 42 are integrally arranged on the side walls of the two clamping plates 34 away from the cooling pipe 14. When the two clamping plates 34 are against each other, the two toothed parts are also spliced ​​to form a ring.

[0049] The second rotating member 43 is a motor, which is fixedly mounted on the outer wall of the rotating box 31 and has an output shaft extending into the rotating box 31. The gear 44 is key-connected to the output shaft of the second rotating member 43 and meshes with the arc-shaped rack 42. The second rotating member 43 drives the gear 44 to rotate, and the rotation of the gear 44 drives the arc-shaped rack 42 and one of the clamping plates 34 to rotate. The movement of the clamping plate 34 drives the other clamping plate 34 to rotate, thereby driving the support member 2 to rotate.

[0050] The heating component 5 is used to heat the support member 2 and make the support member 2 expand. The heating component 5 includes a heating wire 51 and a temperature detector. The heating wire 51 is fixedly installed on the inner wall of the two rotating boxes 31, and the heating wire 51 is located between the support member 2 and the rotating box 31 and is used to heat the support member 2; the temperature detector is fixedly installed in the rotating box 31 and is used to detect the temperature in the rotating box 31.

[0051] When the temperature reaches the specified value, the heating wire 51 stops heating. At the same time, when the support member 2 is mounted and fixed on the cooling pipe 14, the heating wire 51 also stops heating. A cold air duct 16 is fixedly installed on one end of the rotating box 31 away from the cooling pipe 14. The cold air duct 16 faces the support member 2 downward and blows air to cool the support member 2, so that the support member 2 cools down and shrinks quickly and is fixed on the cooling pipe 14.

[0052] The working principle of the embodiment of the present application is as follows: First, the required support member 2 is produced by a spiral mechanism, and the rotating member 1 drives the two rotating boxes 31 to move away from each other. Then the required support member 2 is placed between the two clamping plates 34, and the rotating member 1 drives the two rotating boxes 31 to approach and abut against each other, and the two clamping plates 34 abut against each other to clamp and position the support member 2. The rotating member 2 43 drives the two clamping plates 34 and the support member 2 to rotate. At the same time, the driving member 33 drives the cooling tube 14 to move, and the cooling tube 14 enters the rotating box 31 through the through hole 35, and the heating wire 51 heats the support member 2 to expand it, so that the support member 2 is easier to be mounted and fixed on the cooling tube 14.

[0053] After the installation is completed, the heating wire 51 stops heating, and the cold air duct 16 starts to cool the support 2. At the same time, the cooling pipe 14 continues to output through another through hole 35, and then the support 2 is installed on the cooling pipe 14 and the conductor 12 using the same method. The filling material is then coated on the conductor 12, the cooling pipe 14, and the support 2, and the gap is filled to form the filling member 13. The insulating layer 11 is extruded and coated with the filling member 13 to complete the production of the wire harness, thereby improving the quality and production efficiency of the wire harness.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
