Description

Technical Field

[0001] This application relates to the field of wire harness technology, and in particular to a new energy tensile and torsion resistant wire harness. Background Technology

[0002] A wiring harness is a component in a circuit that connects various electrical devices. It consists of an insulating sheath, terminals, wires, and insulating wrapping material. To facilitate installation and maintenance, and to ensure that electrical equipment can operate under the most severe conditions, the different specifications and colors of wires used by all electrical equipment in the vehicle are arranged in a reasonable manner and bundled together with insulating material. This ensures both completeness and reliability.

[0003] Currently, patent document CN202737399U discloses an automotive wiring harness, including a wiring harness and contact terminals connected to the ends of the wiring harness; it also includes a fixing clamp, which consists of a clamping groove and a snap-on plate. The front end of the clamping groove is connected to three branch grooves, the snap-on plate is fastened to the clamping groove, and the two side plates of the clamping groove hold the outside of the two sides of the clamping groove; the wiring harness is disposed in the clamping groove, and the front end of the wiring harness is divided into three strands and disposed in the three branch grooves respectively. The above-mentioned document solves the problem that the automotive wiring harness is relatively messy, and the direction of the wires cannot be distinguished during the maintenance process, resulting in maintenance difficulties.

[0004] The aforementioned technologies have the following drawbacks: during use, the wire harness is prone to twisting and stretching. If the wire harness is under twisting and stretching for a long time, it is easy to cause the internal sub-wire harness to break, resulting in the wire harness failing to perform its corresponding function. Summary of the Invention

[0005] To reduce the possibility of sub-harness breakage, this application provides a new energy tensile and torsion resistant harness.

[0006] The new energy tensile and torsion resistant wire harness provided in this application adopts the following technical solution:

[0007] A new energy tensile and torsion resistant wire harness includes a wire harness and a thermoplastic tube for fitting the wire harness. The wire harness includes multiple sub-wire harnesses arranged in a ring. After the multiple sub-wire harnesses are arranged in a ring, an installation space is formed inside. A first airbag is disposed in the installation space. The first airbag is elongated and arranged along the length direction of the wire harness. In its initial state, the first airbag is in a free state in the installation space. When the first airbag is inflated to abut against the sub-wire harness, the sub-wire harness is fixedly connected to the first airbag.

[0008] By adopting the above technical solution, multiple sub-wire harnesses are arranged in a ring, then the sub-wire harnesses are sleeved inside a thermoplastic tube. The thermoplastic tube is then heated to shape it. Next, the first airbag is moved into the installation space and inflated with air. During inflation, the volume of the first airbag gradually increases, and it abuts against the side wall of the sub-wire harness, reinforcing it and reducing the possibility of the sub-wire harnesses detaching from the ring. Simultaneously, the first airbag acts as a buffer for the sub-wire harnesses, reducing the possibility of pressure damage and extending their service life. During inflation, the first airbag extends along its length, providing some adjustment for bent wire harnesses. Simultaneously, after the first airbag is fixedly connected to the sub-wire harness, when the entire harness is twisted, the first airbag tends to recover its original shape, thus restoring the harness to its initial state and extending its service life. Furthermore, during use, when the harness is stretched, the first airbag is also stretched, and it tends to recover its original shape, further extending the harness's lifespan.

[0009] Optionally, the cross-section of the first airbag in its inflated state is gear-shaped, and the teeth on the first airbag are located between adjacent sub-wire bundles and fit into the adjacent sub-wire bundles.

[0010] By adopting the above technical solution, when the first airbag is inflated, the adjacent teeth on the first airbag are engaged with a single sub-wire harness, completing the circumferential fixed connection between the first airbag and the sub-wire harness, which is simple and convenient to operate; when the wire harness is twisted, under the action of the teeth, the tendency of the first airbag to restore its deformation is transmitted to the sub-wire harness and then to the wire harness.

[0011] Optionally, both ends of the thermoplastic tube are provided with closing plates. The closing plates have notches for the sub-wire harness to pass through. One of the closing plates is fixedly provided with a hanging ring. The plane of the hanging ring is perpendicular to the plane of the closing plate. The end of the first airbag near the hanging ring is fixedly provided with a hook. The hook has an opening for hooking to the hanging ring. The hook is also provided with a stop bar that is rotatably configured to close the opening. The stop bar is positioned opposite the hanging ring. When the stop bar moves toward the hook, the stop bar abuts against the hook, causing the stop bar to rotate and open the opening. The hook is hooked onto the hanging ring. The other closing plate is detachably provided on the thermoplastic tube. The end of the first airbag away from the hook is fixedly provided on the closing plate.

[0012] By adopting the above technical solution, as the length of the first airbag gradually increases, the first airbag drives the hook to move towards the hanging ring. When the stop bar on the hook abuts against the hanging ring, the stop bar rotates to open the hook, and then the hanging ring enters the hook. The stop bar returns to its initial position to close the opening of the hook, thereby reducing the possibility of the hook and hanging ring falling off. Then, the closing plate at the other end is installed on the thermoplastic tube. Since the first airbag is fixed on the closing plate, when the closing plate is installed on the thermoplastic tube, the axial fixation of the first airbag and the sub-wire harness is completed, so that the wire harness can return to its initial length.

[0013] Optionally, the closing plate is interference-fitted into the thermoplastic tube, and the thermoplastic tube is also provided with a pipe clamp, which is used to lock the closing plate and the thermoplastic tube; the end of the first airbag away from the hook is provided with an air core, which is inserted into the closing plate.

[0014] By adopting the above technical solution, after the closing plate is inserted into the thermoplastic tube, the pipe clamp is fitted onto the thermoplastic tube, and then the diameter of the pipe clamp is adjusted so that the pipe clamp tightly fits the thermoplastic tube onto the closing plate, thus completing the installation of the closing plate. The operation is simple and convenient. The air core is inserted into the closing plate, which facilitates the inflation of the first airbag through the air core.

[0015] Optionally, the outer wall of the first airbag is provided with an injection channel, the injection channel is located between adjacent teeth, and an injection port is opened at the bottom between adjacent teeth. The injection port is connected to the injection channel and abuts against the sub-wire harness. The closing plate is provided with an injection port for injection, and the injection port is connected to the injection channel.

[0016] By adopting the above technical solution, after the closing plate is installed on the thermoplastic tube, adhesive is injected into the injection channel through the injection port. The adhesive enters the outlet along the injection channel and is removed through the outlet. The adhesive enters the contact surface between the sub-wire harness and the first airbag through the outlet, thereby completing the connection between the sub-wire harness and the first airbag and improving the connection stability between the sub-wire harness and the first airbag.

[0017] Optionally, the first airbag includes a plurality of interlocking second airbags, the glue injection channel and the glue outlet are both disposed on the outermost second airbag, the air core is disposed on the innermost second airbag, and the two ends of the second airbag that is interlocked with the outermost second airbag are both fixed to the ends of the interlocking second airbag.

[0018] By adopting the above technical solution, the outermost second airbag has a smaller wall thickness due to the action of the glue injection channel and glue outlet, which makes it easy for the outermost second airbag to be damaged. At this time, when the outermost second airbag is damaged, the second airbag located in the adjacent layer is inserted between the adjacent sub-wire harness to ensure the fixed connection between the sub-wire harness and the second airbag. At the same time, the ends of the outer second airbag and the adjacent second airbag are fixedly connected to ensure that after the outer second airbag is damaged, the adjacent second airbag and the closing plates on both sides are fixedly connected so that the wire harness can return to its initial position under tension.

[0019] Optionally, a fixing rod is provided at the axis of the closing plate, the fixing rod being located on the side opposite to the thermoplastic tube, and the sub-wire harness is bundled onto the fixing rod.

[0020] By adopting the above technical solution, the fixing rod plays a role in fixing and limiting the sub-wire harness that has been removed from the closing plate, so that the sub-wire harness is arranged in a more regular manner.

[0021] Optionally, the fixing rod is hollow and communicates with the first airbag, and the air core is mounted on the fixing rod and communicates with the fixing rod.

[0022] By adopting the above technical solution, after the wire harness has been used for a period of time, the first airbag will leak, which will reduce the limiting effect on the wire harness. At this time, the first airbag will be inflated by the air core to restore the limiting effect of the first airbag on the wire harness. The air core is located on the fixed rod, which reduces the impact of the sub-wire harness on the air core connection and makes it easier to add gas into the first airbag.

[0023] Optionally, the length direction of the air core is perpendicular to the length direction of the fixing rod, and the air inlet of the air core is located outside the sub-wire harness.

[0024] By adopting the above technical solution, the length direction of the air core is perpendicular to the length direction of the fixed rod, so that the distance between the air inlet of the air core and the fixed rod is at its maximum value, which facilitates the connection between the external air source and the air core.

[0025] Optionally, multiple notches are provided, each notch corresponding to a sub-wire harness, and the contact surface between the closing plate and the sub-wire harness is rounded.

[0026] By adopting the above technical solution, the wear between the sub-wire harness and the closing plate is reduced due to the effect of rounded corners, thus further extending the service life of the wire harness.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] 1. Multiple sub-wire harnesses are arranged in a ring, then the sub-wire harnesses are fitted into a thermoplastic tube. The thermoplastic tube is then heated to shape it. The first airbag is then moved into the installation space and inflated with air. During inflation, the volume of the first airbag gradually increases, and it abuts against the side wall of the sub-wire harness, reinforcing it and reducing the possibility of it detaching from the ring. Simultaneously, the first airbag acts as a buffer, reducing the possibility of pressure on the sub-wire harness and extending its service life. As the first airbag expands during inflation, it extends along its length, providing some adjustment for bent wire harnesses.

[0029] 2. After the first airbag is fixedly connected to the sub-wire harness, when the wire harness is twisted as a whole, the first airbag has a tendency to recover, thereby driving the wire harness to return to its initial state and extending the service life of the wire harness; furthermore, during the use of the wire harness, when the wire harness is stretched, the first airbag is stretched, and the first airbag has a tendency to recover its deformation, thereby driving the wire harness to return to its initial length, further extending the service life of the wire harness.

[0030] 3. Due to the action of the glue injection channel and glue outlet, the outermost second airbag has a relatively small wall thickness, which makes it easy for the outermost second airbag to be damaged. In this case, when the outermost second airbag is damaged, the second airbag located in the adjacent layer is inserted between the adjacent sub-wire harness to ensure the fixed connection between the sub-wire harness and the second airbag. At the same time, the ends of the outer second airbag and the adjacent second airbag are fixedly connected to ensure that after the outer second airbag is damaged, the adjacent second airbag and the closing plates on both sides are fixedly connected so that the wire harness can return to its initial position under tension.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a new energy tensile and torsion resistant wire harness. (Refer to...) Figure 1 and Figure 2 The new energy tensile and torsion resistant wire harness includes a wire harness 1 and a thermoplastic tube 2 for connecting the wire harness 1. The wire harness 1 includes multiple sub-wire harnesses 11, which are arranged in a ring and abut against each other. After the multiple sub-wire harnesses 11 are arranged in a ring, an installation space 3 is formed inside. A first airbag 4 is provided in the installation space 3. The first airbag 4 is elongated and arranged along the length direction of the wire harness 1. Further, the first airbag 4 extends along the length direction of the first airbag 4. In the initial state, the first airbag 4 is in a free state in the installation space 3. When the first airbag 4 is inflated to abut against the sub-wire harness 11, the first airbag 4 is cylindrical, and the sub-wire harness 11 is fixedly connected to the first airbag 4.

[0039] During the assembly of wire harness 1, the sub-wire harness 11 is first wound into a ring, then fixed in the above state, and then the thermoplastic tube 2 is sleeved on the outside of the sub-wire harness 11. Then, the first airbag 4 is moved into the installation space 3, and then the first airbag 4 is inflated. When the first airbag 4 is inflated, the length and diameter of the first airbag 4 increase and abut against the sub-wire harness 11. Then, the fixation of the sub-wire harness 11 is released, and the thermoplastic tube 2 is heated to install the sub-wire harness 11 between the first airbag 4 and the thermoplastic tube 2. After the wire harness 1 is installed, under the action of the first airbag 4, the twisting and stretching of the wire harness 1 are limited to a certain extent, so that the wire harness 1 has a tendency to recover its deformation after twisting and stretching, thereby improving the tensile and torsional resistance of the wire harness 1 and extending the service life of the wire harness 1.

[0040] Reference Figure 1 and Figure 2 In this embodiment of the application, the first airbag 4 and the sub-wire harness 11 are fixedly connected in two directions: the first airbag 4 and the sub-wire harness 11 are fixedly connected in the circumferential direction and in the axial direction.

[0041] Reference Figure 1 and Figure 2When the first airbag 4 and the sub-wire harness 11 are circumferentially fixedly connected, the cross-section of the first airbag 4 in the inflated state is gear-shaped, and the teeth 5 on the first airbag 4 are located between adjacent sub-wire harnesses 11 and fit against the adjacent sub-wire harnesses 11. The distance between adjacent teeth 5 is equal to the diameter of the sub-wire harness 11. When the first airbag 4 is in the inflated state, the sub-wire harness 11 is engaged in the engaging groove 6 formed between adjacent teeth 5, thereby completing the fixed connection between the sub-wire harness 11 and the first airbag 4.

[0042] Reference Figure 3 and Figure 4 To improve the stability of the circumferential fixed connection between the first airbag 4 and the sub-wire harness 11, an adhesive injection channel 7 is provided on the outer wall of the first airbag 4. Furthermore, the adhesive injection channel 7 is located within the wall thickness of the first airbag 4, between adjacent teeth 5, and directly below the snap-fit ​​groove 6. An adhesive outlet 8 is provided at the bottom between adjacent teeth 5, and the adhesive outlet 8 is connected to the adhesive injection channel 7. The adhesive outlet 8 abuts against the sub-wire harness 11. After the sub-wire harness 11 is snapped into the snap-fit ​​groove 6 on the first airbag 4, adhesive is injected into the adhesive injection channel 7. The adhesive entering the adhesive injection channel 7 flows out through the adhesive outlet 8. Under the action of the adhesive, the first airbag 4 and the sub-wire harness 11 are connected as a whole, thereby improving the connection stability between the first airbag 4 and the sub-wire harness 11.

[0043] Reference Figure 3 and Figure 5 When the first airbag 4 is axially fixedly connected to the sub-wire harness 11, both ends of the thermoplastic tube 2 are provided with closing plates 9. The closing plates 9 have notches 10 for the sub-wire harness 11 to pass through. A hanging ring 12 is fixedly provided on one closing plate 9, and the plane of the hanging ring 12 is perpendicular to the plane of the closing plate 9. A hook 13 is fixedly provided on the end of the first airbag 4 near the hanging ring 12. The hook 13 has an opening for hooking onto the hanging ring 12. A stop bar 14 with a rotatable closing opening is also provided on the hook 13. In this embodiment, the rotation axis of the stop bar 14 is parallel to... On the plane where the hanging ring 12 is located, the stop bar 14 is set directly opposite the hanging ring 12. When the stop bar 14 moves toward the hook 13, the stop bar 14 abuts against the hook 13, causing the stop bar 14 to rotate and open the opening, and the hook 13 is hooked onto the hanging ring 12. When the first airbag 4 inflates and extends, the first airbag 4 causes the hook 13 to move toward the hanging ring 12. When the stop bar 14 abuts against the hanging ring 12, the stop bar 14 rotates toward the hook 13. When the stop bar 14 disengages from the hanging ring 12, the connection between the hook 13 and the hanging ring 12 is completed, thereby completing the fixed connection between the wire harness 1 and one end of the first airbag 4.

[0044] Reference Figure 3 and Figure 5To reduce the possibility of the hook 13 and the hanging ring 12 falling off, a hinge shaft 15 is fixedly installed on the hook 13, and a stop bar 14 is fixedly installed on the hinge shaft 15. Furthermore, the stop bar 14 is located inside the hook 13, and the length of the stop bar 14 is greater than the length of the opening and less than the diameter of the hook 13. Furthermore, a torsion spring is sleeved on the hinge shaft 15, with one side of the torsion spring fixedly installed on the stop bar 14 and the other side fixedly installed on the hinge shaft 15. When the hanging ring 12 enters the hook 13, under the action of the torsion spring, the stop bar 14 is driven to rotate to abut against the hook 13, closing the opening of the hook 13, thereby reducing the possibility of the hook 13 and the hanging ring 12 falling off.

[0045] Reference Figure 3 and Figure 4 In this embodiment, the end of the first airbag 4 away from the hook 13 is fixedly mounted on the closing plate 9. The closing plate 9 is detachably mounted on the thermoplastic tube 2. The closing plate 9 is inserted into the thermoplastic tube 2 with an interference fit. The thermoplastic tube 2 is also provided with a tube clamp 16, which is used to lock the closing plate 9 and the thermoplastic tube 2. The end of the first airbag 4 away from the hook 13 is fixedly connected to the wire harness 1. The closing plate 9 is inserted into the thermoplastic tube 2. Then, the tube clamp 16 is fitted onto the thermoplastic tube 2 and made to overlap with the closing plate 9. The diameter of the tube clamp 16 is then adjusted to lock the thermoplastic tube 2 onto the closing plate 9, thus completing the fixing operation of the closing plate 9 and the fixing operation of the first airbag 4 and the thermoplastic tube 2. The operation is simple and convenient.

[0046] Reference Figure 3 and Figure 4 In this embodiment of the application, multiple notches 10 are provided, and each notch 10 is provided in a one-to-one correspondence with a sub-wire harness 11. The contact surface between the closing plate 9 and the sub-wire harness 11 is provided with rounded corners. Under the action of the rounded corners, the wear degree between the sub-wire harness 11 and the closing plate 9 is reduced, and the service life of the sub-wire harness 11 is extended.

[0047] Reference Figure 3 and Figure 4 In this embodiment of the application, the closing plate 9 of the hook 13 is provided with an injection port for injection, and the injection port is connected to the injection channel 7.

[0048] Reference Figure 3 and Figure 4 After the closing plate 9 seals both ends of the thermoplastic tube 2, in order to facilitate the addition of gas to the first airbag 4, an air core 17 is provided at the end of the first airbag 4 away from the hook 13, and the air core 17 is inserted into the closing plate 9.

[0049] Reference Figure 3 and Figure 4The first airbag 4, due to the presence of an injection channel 7 and an outlet 8, suffers damage to its integrity, reducing its lifespan and consequently decreasing its ability to restore the wire harness 1 to its original shape. To ensure the first airbag 4's constraint on the wire harness 1, it comprises multiple interconnected second airbags 41. The injection channel 7 and outlet 8 are located on the outermost second airbag 41, while the air core 17 is located on the innermost second airbag 41. The two ends of the second airbag 41 nested within the outermost second airbag 41 are fixed to the ends of the nested second airbag 41. Furthermore, a hook 13 is located at the end of the outermost second airbag 41, and the end of the outermost second airbag 41 facing away from the hook 13 is fixed to the closing plate 9. Simultaneously, the ends of the inner second airbags 41 are fixedly connected to each other. When the outermost second airbag 41 is damaged, the adjacent second airbags 41 provide a connection and constraint for the wire harness 1, improving its torsional and tensile strength.

[0050] Reference Figure 1 and Figure 3 To facilitate the integration of the sub-wire harness 11 on the outside of the thermoplastic tube 2, a fixing rod 18 is fixedly installed at the axis of the closing plate 9. The length direction of the fixing rod 18 is perpendicular to the plane where the closing plate 9 is located. The fixing rod 18 is located on the side away from the thermoplastic tube 2, and the sub-wire harness 11 is tied to the fixing rod 18.

[0051] Reference Figure 1 and Figure 3 Furthermore, after the sub-wiring harness 11 is integrated, in order to facilitate the inflation of the second airbag 41 through the sub-wiring harness 11, the fixing rod 18 is hollow and connected to the first airbag 4. The air core 17 is set on the fixing rod 18 and connected to the fixing rod 18. Furthermore, the length direction of the air core 17 is perpendicular to the length direction of the fixing rod 18, and the air inlet of the air core 17 is located outside the sub-wiring harness 11. The length direction of the air core 17 is perpendicular to the length direction of the fixing rod 18, so that the distance between the air inlet of the air core 17 and the fixing rod 18 is at its maximum value, thereby facilitating the connection between the external air source and the air core 17.

[0052] The implementation principle of a new energy tensile and torsion resistant wire harness in this application embodiment is as follows:

[0053] During the assembly of wire harness 1, the sub-wire harness 11 is first wrapped into a ring, then the sub-wire harness 11 is fixed in the above state, and then the thermoplastic tube 2 is sleeved on the outside of the sub-wire harness 11; then the first airbag 4 is moved into the installation space 3, and then the first airbag 4 is inflated. When the first airbag 4 is inflated, the length and diameter of the first airbag 4 increase and abut against the sub-wire harness 11. Then the fixation of the sub-wire harness 11 is released, and then the thermoplastic tube 2 is heated to install the sub-wire harness 11 between the first airbag 4 and the thermoplastic tube 2.

[0054] Then, one end of the thermoplastic tube 2 is closed by the closing plate 9. During the extension process, the first airbag 4 drives the hook 13 to move toward the hanging ring 12. When the stop bar 14 abuts against the hanging ring 12, the stop bar 14 rotates toward the hook 13. When the stop bar 14 is separated from the hanging ring 12, the connection between the hook 13 and the hanging ring 12 is completed, thereby completing the fixed connection between the wire harness 1 and one end of the first airbag 4.

[0055] Next, insert another closed plate 9 into the thermoplastic tube 2, and then fit the tube clamp 16 onto the thermoplastic tube 2; then inject adhesive into the adhesive channel 7 through the adhesive injection port, and the adhesive flows out through the adhesive outlet 8 to fix the first airbag 4 and the sub-wire harness 11, thus completing the installation of the wire harness 1; under the action of the first airbag 4, the tensile and torsional resistance of the wire harness 1 is improved.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
