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 relying solely on the cable itself to dissipate heat is slow. Therefore, for safety reasons, the current passing through the cable harness can only be limited. Increasing the current will increase the safety risk of the cable harness. Summary of the Invention

[0004] In order to increase the current passing through the cable harness and reduce the safety risks 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 that adopts the following technical solution:

[0006] A charging harness includes an insulating layer, a conductor located within the insulating layer, a filler, and a cooling tube. A cooling medium is stored in or passed into the cooling tube in real time. The filler is made of PE, PP, or Teflon.

[0007] By adopting the above technical solution, the cooling medium is stored or introduced into the cooling pipe in real time. At the same time, 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. Therefore, it is possible to increase the current passing through the wiring harness and reduce the safety risks during the operation of the cable harness.

[0008] Optionally, support members made of metal are provided on the outer side walls of the cooling tube and the conductor, and the support members are used to support the cooling tube and conduct the heat generated by the conductor to the cooling medium in the cooling tube.

[0009] By adopting the above technical solution, the cooling tube and the conductor are generally made of soft materials, which results in poor strength of the cooling tube and the conductor. When the cable harness is subjected to compression and tensile forces, the cooling tube is easily deformed, 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.

[0010] The support member made of metal supports the cooling pipe and the conductor, thereby reducing the probability of deformation of the cooling pipe and the conductor when the external environment is subjected to pressure and tensile force, and when the wire harness is subjected to extrusion and tensile force, the support member can disperse the force, thereby reducing the risk of deformation of the cooling pipe and the conductor. In addition, the support member made of metal can further improve the heat dissipation effect of the wire harness, increase the current passing through the wire harness, and reduce the safety risk of the wire harness during operation.

[0011] Optionally, the support member is a metal wire spirally wound on the outer wall of the cooling pipe or the conductor, the metal wire forms a plurality of spiral connecting segments abutting each other, adjacent two connecting segments form annular positioning cavities and filling cavities on the side close to the cooling pipe and the filler, the metal wire is pressed on the cooling pipe and forms a plurality of positioning portions on the cooling pipe which are extruded into the positioning cavities and abut the connecting segments, and the filler forms a filling portion in the filling cavity when filled.

[0012] By adopting the above technical solution, the support member is formed by winding the metal wire, so that the manufacturing process is relatively simple. In addition, the plurality of spiral connecting segments extrude the cooling pipe, so that the cooling pipe is slightly deformed to form the positioning portions in the positioning cavities, thereby enabling the metal wire to be integrated with the cooling pipe. The filler forms the filling portion in the filling cavity, so that the filler, the insulating layer, and the support member are integrated to support the force, such as tension and pressure, acting 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 risk of the wire harness during operation.

[0013] In addition, the metal wire has elasticity. When the wire harness is bent and twisted, the connecting segments can be buffered under the action of the elastic force, thereby reducing the resistance of the metal pipe generated when the wire harness is bent and twisted, reducing the adverse effects on the normal function of the wire harness, further increasing the current passing through the wire harness, and reducing the safety risk of the wire harness during operation.

[0014] Optionally, the support members on the two cooling pipes and the conductor abut each other and the connecting segments on one support member extend into the filling cavity on the other support member.

[0015] By adopting the above technical solution, the support member can also support the conductor, and further accelerate the heat generated by the conductor to be dissipated. In addition, the support members on the cooling pipe and the conductor abut each other, thereby further improving the force support and dispersion effect, further increasing the heat dissipation effect of the wire harness, further increasing the current passing through the wire harness, and reducing the safety risk of the wire harness during operation.

[0016] Optionally, it further 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.

[0017] 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.

[0018] In a second aspect, the present application provides a production process that adopts the following technical solution:

[0019] A production process comprises the following steps:

[0020] Production of support parts: multiple support parts are produced through a spiral mechanism;

[0021] Installing support members: installing multiple support members on the outer side walls of the cooling tube and the conductor through the installation mechanism;

[0022] Extruded filler: The filler material is coated on the conductor, cooling tube, and support member and the gap is filled to form a filler;

[0023] Extruded insulation layer: The insulation layer is formed by extrusion and the filler is covered.

[0024] 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.

[0025] The support member is produced by a spiral mechanism, and then the support member is fixedly mounted on the outer wall of the cooling tube and the conductor through an installation mechanism. The filling material is then coated on the conductor, cooling tube and support member to form a filler, and finally an insulating layer is extruded to form the filler. The insulating layer coats the filler, 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.

[0026] Optionally, the mounting mechanism includes:

[0027] Two rotating boxes, the bottom of which is rotatably arranged on the machine body and moves closer to or away from each other;

[0028] Multiple sets of rotating wheels, rotatably mounted on two rotating boxes;

[0029] a driving member for driving the rotating wheels to rotate and for enabling the cooling pipe or the conductor to move;

[0030] two clamping plates, which are arranged in two rotating boxes, the two rotating boxes are close to each other and enable the two clamping plates to be close to the clamping support and enable the support to be located in the rotating boxes; or, the two rotating boxes are away from each other and facilitate the support to be put in;

[0031] a driving assembly for driving the two rotating boxes to rotate and the two clamping plates to rotate;

[0032] a heating assembly for heating the support and enabling the support to expand.

[0033] By adopting the above technical scheme, the driving assembly is started to drive the two rotating boxes to be away from each other, and then the support can be put in. The driving assembly is started to drive the two rotating boxes to abut against each other, and the two clamping plates clamp and position the support. The driving member drives the plurality of rotating wheels to rotate, the rotating wheels drive the cooling pipe to move, and the driving assembly drives the two clamping plates and the support to rotate, so that the support can be sleeved on the cooling pipe. After the cooling pipe is extruded and deformed, the cooling pipe enters the positioning cavity. At the same time, the heating assembly heats and expands the support, so that the inner diameter of the support increases due to the expansion, and the cooling pipe is more convenient to pass through the support. When the support is sleeved on the cooling pipe, the heating assembly stops heating, so that the support cools and shrinks, and the volume of the cooling pipe entering the positioning cavity is increased, so that the installation process is more convenient and stable, thereby improving the quality and production efficiency of the wire harness, increasing the current of the wire harness, and reducing the safety risk of the wire harness in operation.

[0034] Optionally, the driving assembly comprises:

[0035] a rotating member one for driving the two rotating boxes to rotate;

[0036] two arc-shaped racks, which are arranged on the two clamping plates respectively

[0037] a rotating member two, which is arranged on the outer side wall of the rotating box;

[0038] a gear, which is arranged on the output shaft of the rotating member two and is meshed with the arc-shaped rack.

[0039] 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 fixedly installed on the cooling pipe or conductor.

[0040] 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 support parts can be placed in for production, thereby improving the stability and convenience of the production process and improving the quality and production efficiency of the wire harness.

[0041] Optionally, the heating component includes:

[0042] A heating wire is disposed in the rotating box and is used to heat the support member;

[0043] Temperature detector, used to detect the temperature inside the rotating box.

[0044] 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.

[0045] Optionally, a cold air pipe 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.

[0046] 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 extrusion 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.

[0047] In summary, this application includes at least one of the following beneficial technical effects:

[0048] 1. By storing or introducing the cooling medium in the cooling pipe in real time, and using PE, PP or Teflon filling materials with good heat dissipation effect for the filling parts, the filling parts and the cooling medium cooperate to dissipate heat from the conductor, thereby greatly improving the heat dissipation effect of the wiring harness. This can increase the current passing through the wiring harness and reduce the safety risks during the operation of the cable harness.

[0049] 2. 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. Moreover, when the wiring harness is subjected to extrusion and tensile force, the supports 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.

[0065] With reference to Figure 3 and Figure 4 , the support 2 is a metal wire spirally wound on the outer side wall of the conductor 12 and abutting against each other, and the metal wire is preferably made of copper, aluminum or the like; the metal wire is formed with a plurality of connecting segments 21 abutting against each other and in a spiral shape, an annular positioning cavity 22 is formed between adjacent two connecting segments 21 and located close to the conductor 12, and an annular filling cavity 23 is formed between the two connecting segments 21 and located close to the filler 13.

[0066] The metal wire presses on the cooling pipe 14 to form a certain extrusion force on the conductor 12, the extrusion force causes the conductor 12 to be extruded and deformed to form a positioning part 24 into the positioning cavity 22, and the filling part 25 is formed in the filling cavity 23 when the filling part 13 is filled, the positioning part 24 and the filling part 25 connect the support 2, the cooling pipe 14, the conductor 12 and the filling part 13 into an integral whole, when the wire harness is subjected to an action force such as extrusion or tension, the support 2 can disperse the action force, greatly reducing the risk of deformation and damage of the cooling pipe 14, the conductor 12 and the filling part 13, and improving the stability of the wire harness during operation.

[0067] The two supports 2 located on the cooling pipe 14 and the conductor 12 and located 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 more quickly conducted to the cooling pipe 14, and in addition, the support 2 can also reduce the risk of deformation of the cooling pipe 14, thereby greatly improving the cooling effect of the wire harness and increasing the current passing through the wire harness and reducing the safety risk during operation of the wire harness.

[0070] The embodiment of the present application discloses a production process.

[0071] Referring to Figure 2 , Figure 5 and Figure 6 , the production process comprises the following steps:

[0072] Producing the support 2: a plurality of supports 2 are produced by a spiral mechanism, the spiral mechanism can adopt existing spring production equipment or other equipment, as long as it can produce the support 2.

[0073] Installing the support 2: the plurality of supports 2 are installed on the outer side walls of the cooling pipe 14 and the conductor 12 by the installation mechanism 3;

[0074] Extruding the filling part 13: the filling material is wrapped on the conductor 12, the cooling pipe 14 and the support 2, and the gap is filled to form the filling part 13;

[0075] Extruded insulation layer 11: The insulation layer 11 is formed by extrusion and the filler 13 is covered.

[0076] The installation process of the cooling tube 14 is the same as that of the conductor 12. The cooling tube 14 is explained below as an example. 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 is 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 is close to each other at one end 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.

[0077] Multiple 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. Each group of rotating wheels 32 is arranged in a circular array around the axis of the through hole 35. Multiple driving members 33 are provided and are arranged one-to-one corresponding to the multiple 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 multiple rotating wheels 32 located at the entrance end of the cooling pipe 14 are pressed against the cooling pipe 14, and the multiple rotating wheels 32 located at the output end of the cooling pipe 14 are pressed against the support member 2 for positioning, thereby driving the cooling pipe 14 to enter or output.

[0078] 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 as the number of support members 2 increases, the number of clamping plates 34 increases accordingly.

[0079] 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 arcuate 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 arcuate 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.

[0080] Rotating member 43 is a motor. Rotating member 43 is fixedly mounted on the outer wall of rotating housing 31, with its output shaft extending into the housing. Gear 44 is keyed to the output shaft of rotating member 43 and meshes with arcuate rack 42. Rotating member 43 drives gear 44, which in turn rotates arcuate rack 42 and one of the clamping plates 34. The movement of one clamping plate 34 drives the other clamping plate 34, thereby driving support member 2 to rotate.

[0081] 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 mounted 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 mounted in the rotating box 31 and is used to detect the temperature in the rotating box 31.

[0082] When the temperature reaches the specified value, the heating wire 51 stops heating. At the same time, when the support member 2 is fixedly mounted on the cooling pipe 14, the heating wire 51 also stops heating. A cold air pipe 16 is fixedly mounted on one end of the rotating box 31 away from the cooling pipe 14. The cold air pipe 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.

[0083] The working principle of the embodiment of this application is as follows:

[0084] 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. 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 pipe 14 to move. The cooling pipe 14 enters the rotating box 31 through the through hole 35, and the heating wire 51 heats the support member 2 to expand it, making it easier for the support member 2 to be fixedly installed on the cooling pipe 14.

[0085] After the installation is completed, the heating wire 51 stops heating, and the cold air pipe 16 starts to cool the support 2. At the same time, the cooling pipe 14 continues to output through another through hole 35. Then, the same method is used to install the support 2 on the cooling pipe 14 and the conductor 12. 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.

[0086] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
