Description

Technical Field

[0001] The present invention relates to the field of automotive wiring harness processing. Specifically, it relates to an anti-tangling device for automotive wiring harnesses and its usage method. Background Art

[0002] An automotive wiring harness is the main network of an automotive circuit. A wiring harness refers to a component formed by pressing contact terminals (connectors) made of copper into wires and cables, and then molding an insulator outside or adding a metal shell, etc., and bundling the wires and cables to form a component for connecting the circuit.

[0003] When an automotive wiring harness is being produced and processed, usually the raw material in bundles of cables is cut into different specifications first, then the ends are peeled to expose the metal ends at the cut ends, and terminals are pressed at the metal ends. After that, the cables are assembled according to the circuit diagram and bundled into a wiring harness. Therefore, cutting into different length specifications in the early stage is an essential process. After cutting and before the terminals are pressed, cables of the same specification need to be bundled and stored for later use, and then supplied to the workstations according to the requirements of different types of wiring harnesses. Therefore, the wiring harness must be prevented from tangling during storage. Otherwise, the subsequent material taking process will be delayed. Currently, bundling and storing the cables to avoid tangling are all done by using straps. Most of these straps are disposable. Bundling is convenient, but removing them requires the assistance of tools such as scissors. Since they are disposable, a lot of plastic waste will be generated for recycling. Therefore, there is an urgent need for a device that can not only prevent the wiring harnesses from tangling with each other during use but also be reused.

[0004] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0018] S2. Rotate and adjust the top ring through the handle until the arc-shaped piece moves towards the wires and stably clamps the wires.

[0019] S3. Move the connecting piece outside the wire clamping assembly towards the locking piece until the locking post is inserted into the housing body and locked.

[0020] S4. Rotate the adjusting handle to adjust the length of the folding frame until the whole wire harness is arranged in a straight line.

[0021] S5. If the folding frame in S4 has reached the length critical value and the whole wire harness still does not show a straight line, pull out the positioning pin and rotate the outer sleeve so that the whole wire harness is spirally wound around the outside of the first sleeve and the second sleeve, then insert the positioning pin into the positioning hole, and finally hoist the wire harness on the wire storage rack through the hook for later use.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

The wire clamping assembly is also installed outside the installation sleeve through the outer sleeve, and the distance between the two wire clamping assemblies can be adjusted by the folding frame. Therefore, when the lengths of the wire harnesses to be stored are different, the distance between the wire clamping assemblies at both ends can be changed to store wire harnesses of different lengths. Moreover, the wire clamping assembly can also rotate outside the installation sleeve through the outer sleeve. When the wire harness is too long, the outer sleeve can be rotated to make the wire harness spirally wound around the outside of the first sleeve and the second sleeve to avoid the wire harness from loosening. At the same time, the wire clamping assembly is connected to the locking piece provided outside the outer sleeve through the connecting piece. The setting of the locking piece enables the locking of the locking post provided at the end of the connecting piece to be achieved only by simple pushing, and the locking of the locking post can be released only by pushing again later. Thus, the quick disassembly of the wire clamping assembly can be realized, and it is also convenient for the quick picking and placing of the wire harness during subsequent use.

[0024] The wire clamping assembly provided by the present invention uses arc-shaped pieces to achieve contraction and expansion. Synchronous contraction of multiple arc-shaped pieces can effectively clamp and fix the ends of wire harnesses with different overall thicknesses. The process only requires a simple rotation of the top ring, and it is also very convenient and fast to pick up and place single wire harnesses subsequently. Brief Description of the Drawings

[0051] Next, in combination with the accompanying drawings and specific implementation manners, the invention will be further described:

[0052] Example 1: Please refer to Figures 1-4 , a wire harness anti-tangling device for an automobile according to an embodiment of the present invention includes two relatively arranged installation sleeves 1. An outer sleeve 2 is sleeved outside the installation sleeve 1. A wire clamping assembly 3 is installed on the outer wall of the outer sleeve 2. Hanging brackets 4 are fixedly installed at the ends of the two installation sleeves 1 away from each other. Hooks 5 are fixedly installed at the ends of the hanging brackets 4 away from the installation sleeves 1. A connecting plate 6 is arranged between the two installation sleeves 1. First sleeves 7 are fixedly installed on the two end faces of the connecting plate 6. Second sleeves 8 are fixedly installed inside the ends of the installation sleeves 1 facing the connecting plate 6. The second sleeves 8 are sleeved outside the adjacent first sleeves 7. A folding frame 9 is also fixedly installed inside the installation sleeves 1. The end of the folding frame 9 away from the installation sleeve 1 is fixedly installed on the connecting plate 6. An end cover 10 is also fixedly installed inside the end of the installation sleeve 1 away from the connecting plate 6.

[0053] The end of the wire harness to be assembled is clamped by the wire clamping assembly 3. The wire clamping assemblies 3 on the outer sleeves 2 sleeved outside the two mounting sleeves 1 can fix the two ends of the wire harness respectively. The distance between the mounting sleeve 1 and the connecting plate 6 can be adjusted through the folding frame 9. Therefore, the distance between the wire clamping assemblies 3 on the two outer sleeves 2 can be adjusted, and the distance between the two outer sleeves 2 can be changed according to the actual length of the wire harness, so that the wire harness can be stably arranged between the two wire clamping assemblies 3.

[0054] Please refer to Figures 5-6 , in order to enable the folding frame 9 to adjust the distance between the mounting sleeve 1 and the connecting plate 6, in this embodiment, the folding frame 9 includes a plurality of square frames 11 arranged in parallel. A connecting sleeve 12 is integrally provided at the center inside the square frame 11. A short rod 14 is hingedly installed at the middle of the outer side wall of the square frame 11 located at both ends, and a long rod 13 is hingedly installed at the middle of the outer side wall of the square frame 11 located in the middle. The ends of the long rods 13 at the middle of the outer side walls of two adjacent square frames 11 located in the middle are hinged to each other. The end of the long rod 13 at the middle of the outer side wall of the square frame 11 close to the end is hinged to the end of the short rod 14. A lead screw 15 is rotatably installed through the connecting sleeve 12 far from the connecting plate 6. A wire sleeve 16 is fixedly installed inside the connecting sleeve 12 located in the middle. The wire sleeve 16 is arranged close to the mounting sleeve 1, and the lead screw 15 is screwed with the wire sleeve 16. One end of the lead screw 15 far from the wire sleeve 16 passes through the inside of the mounting sleeve 1 and is fixedly installed with an adjusting handle 17. Rotate the adjusting handle 17. The adjusting handle 17 can drive the lead screw 15 to rotate. The rotation of the lead screw 15 will drive the connecting sleeve 12 connected to the wire sleeve 16 to move through the wire sleeve 16. The connecting sleeve 12 can drive the square frame 11 located in the middle to move synchronously. The lead screw 15 is also rotatably connected to the connecting sleeve 12 located at the end. Therefore, the distance between the square frame 11 at the end and the square frame 11 in the middle will be changed, and then the distance between the connecting plate 6 and the mounting sleeve 1 will be changed.

[0055] In order to enable the folding frame 9 to be stably connected to the connecting plate 6, in this embodiment, a positioning column 18 is fixedly installed in the middle of the connecting plate 6. The connecting sleeve 12 far from the mounting sleeve 1 is fixedly installed on the positioning column 18, and the square frame 11 far from the connecting plate 6 can be fixedly installed inside the mounting sleeve 1. With such a setting, when the lead screw 15 is rotated and adjusted, the distance between the mounting sleeve 1 and the connecting plate 6 can be stably adjusted.

[0056] Please refer to Figures 7-9, in order to enable the wire clamping assembly 3 to be rotationally adjusted in position outside the mounting sleeve 1, in this embodiment, an annular groove 22 is formed in the outer wall of the mounting sleeve 1. One end of the outer sleeve 2 facing the connecting plate 6 is arranged in the annular groove 22. Rotating the outer sleeve 2 can make the outer sleeve 2 move in the annular groove 22, thereby changing the position of the wire clamping assembly 3. The adjusted folding frame 9 can store and limit a longer wire harness. If the wire harness is even longer, the position of the wire clamping assembly 3 can be changed so that the wire harness is spirally wound around the outside of the first sleeve 7 and the second sleeve 8, thus enabling the storage and limitation of an even longer wire harness. A plurality of positioning holes 19 are formed in the side wall of the mounting sleeve 1, and positioning pins 20 are inserted into the side wall of the outer sleeve 2. After rotating the outer sleeve 2, the position of the outer sleeve 2 can be positioned by inserting the positioning pins 20 into the positioning holes 19.

[0057] , in order to enable the lead screw 15 to more stably adjust the telescopic folding of the folding frame 9, in this embodiment, a mounting hole 21 is formed in the center of the end cap 10. The lead screw 15 passes through the mounting hole 21 and is also rotatably connected to the end cap 10 through a mounting bearing (not shown in the figure).

[0058] , in order to ensure that the folding frame 9 can be stably connected to the mounting sleeve 1, in this embodiment, an assembly plate 23 is fixedly installed inside the mounting sleeve 1. The assembly plate 23 is annularly arranged, and a clamping plate 24 is fixedly installed at the bottom of the end face of the assembly plate 23 facing the connecting plate 6. The square frame 11 arranged away from the connecting plate 6 is fixedly installed on the assembly plate 23 through the clamping plate 24.

[0059] Please refer to Figures 10-17, in order to enable the quick disassembly between the wire clamping component 3 and the outer sleeve 2, in this embodiment, an annular protrusion 25 is integrally provided on the outer wall of the outer sleeve 2, and a plurality of protrusions 26 are fixedly installed on the outer wall of the annular protrusion 25. A locking member 27 is fixedly installed at one end of the protrusion 26 away from the annular protrusion 25. A connecting member 28 is fixedly installed on the outer side wall of the wire clamping component 3, and one end of the connecting member 28 away from the wire clamping component 3 is connected to the locking member 27. The locking member 27 includes an outer shell 29. One end of the outer shell 29 is open, and the other end of the outer shell 29 is fixedly installed on the protrusion 26. An insertion block 30 is slidably arranged inside the outer shell 29. Clamping blocks 31 are integrally provided on both sides of one end of the insertion block 30 facing the opening of the outer shell 29. A limiting hole 32 is opened on one side wall of the outer shell 29, and a sliding hole 41 is opened on the other side wall of the outer shell 29 opposite to the limiting hole 32. A retaining groove 321 is provided in the middle of the inner wall of one side of the limiting hole 32 close to the opening of the outer shell 29, and a guiding block 322 is provided on the inner wall of the other side of the limiting hole 32 away from the opening end of the outer shell 29. The guiding block 322 faces the retaining groove 321. A sliding outlet 323 located inside the outer shell 29 is opened at one end of the limiting hole 32 away from the guiding block 322. A first raised block 33 and a second raised block 34 are integrally provided on the inner wall of the outer shell 29 where the limiting hole 32 is opened, and the sides of the first raised block 33 and the second raised block 34 facing the limiting hole 32 are arranged along the length direction of the limiting hole 32. A swing rod 37 is installed on the outer wall of one side of the insertion block 30 facing the limiting hole 32. One end of the swing rod 37 facing the clamping block 31 is swingably connected to the insertion block 30, and a guide post 38 is fixedly installed at the other end of the swing rod 37 away from the clamping block 31. The guide post 38 is arranged away from the insertion block 30. An inclined surface 341 is opened on one side surface of the second raised block 34 away from the first raised block 33. A top groove 39 is opened on one side surface of the insertion block 30 away from the swing rod 37. A spring 36 is arranged in the top groove 39, and one end of the spring 36 away from the top groove 39 abuts against the inner wall of the top end of the outer shell 29.

[0060] Move the end of the connecting member 28 away from the wire clamping assembly 3 towards the inside of the housing 29. At this time, the end of the connecting member 28 can push the insertion block 30 to squeeze the spring 36 and penetrate deeper into the housing 29. When the insertion block 30 moves, it will drive the swing rod 37 to move synchronously. When the guide post 38 at the end of the swing rod 37 contacts the inclined surface 341, the swing rod 37 can be swung by the guide post 38 until the guide post 38 moves into the limit hole 32 through the inclined surface 341. At this time, continuing to push the insertion block 30 will cause the guide post 38 to contact the guide block 322. Then release the force applied to the wire clamping assembly 3. The spring 36 will give the insertion block 30 a reverse acting force. When the insertion block 30 moves in the reverse direction, the swing rod 37 will drive the guide post 38 to return to its original position. However, due to the effect of the guide block 322, the guide post 38 will move towards the retaining groove 321 until the guide post 38 moves into the retaining groove 321 and is limited. At this time, the insertion block 30 will be limited within the housing 29, and the two clamping blocks 31 integrally provided at the end of the insertion block 30 will approach each other due to the size of the open end of the housing 29. The end of the connecting member 28 is clamped by the two clamping blocks 31, so that the wire clamping assembly 3 is positioned outside the outer sleeve 2. When a force is applied to the connecting member 28 towards the wire clamping assembly 3 again, the insertion block 30 will drive the swing rod 37 to move again. The swing rod 37 will also drive the guide post 38 to move towards the first protrusion block 33. Then release the force applied to the connecting member 28. At this time, due to the effect of the guide block 322, the guide post 38 cannot return to its original position along the original position, and the guide post 38 can only slide out through the sliding outlet 323. When the guide post 38 leaves the limit hole 32, the insertion block 30 will also drive the clamping block 31 to move out of the housing 29, and then release the clamping of the end of the connecting member 28.

[0061] In order to ensure the stable installation of the spring 36, in this embodiment, an insertion post 35 is fixedly installed on the inner wall of the end of the housing 29. One end of the spring 36 away from the top groove 39 is inserted outside the insertion post 35. On the opposite side surfaces of the two clamping blocks 31 away from the insertion block 30, a clamping head 311 is integrally provided. On the side surface of the insertion block 30 away from the swing rod 37, a sliding block 40 is also integrally provided. The sliding block 40 slides in the sliding hole 41.

[0062] Please refer to Figure 18, in order to enable the connecting member 28 to stably connect the wire clamping assembly 3 and the locking member 27, in this embodiment, the connecting member 28 includes a plug board 42. The side surface of the plug board 42 facing the wire clamping assembly 3 is provided with an arc-shaped groove. And an insertion rod 43 is integrally provided on the outer wall of the plug board 42 facing the wire clamping assembly 3. A positioning groove 44 is formed at the top of the plug board 42, and a positioning plate 45 is inserted into the positioning groove 44. A locking column 46 is integrally provided on the side wall of the plug board 42 away from the insertion rod 43, and a trapezoidal head 47 is integrally provided at one end of the locking column 46 away from the plug board 42. The insertion rod 43 is connected to the wire clamping assembly 3. The locking column 46 can drive the trapezoidal head 47 to insert into the inner part of the outer shell 29, and the trapezoidal head 47 is clamped by the chuck 311 at the end of the clamping block 31, so as to realize the locking and limiting between the connecting member 28 and the locking member 27. Only by simple pushing can rapid assembly and disassembly be achieved.

[0063] Through the above solution of the present invention, the wire clamping assembly 3 provided by the present invention can clamp both ends of the wire harness, so as to stably store the wire harness to be assembled. The wire clamping assembly 3 is also installed outside the mounting sleeve 1 through the outer sleeve 2, and the distance between the two wire clamping assemblies 3 can be adjusted by the folding frame 9. Therefore, when the lengths of the wire harnesses to be stored are different, the storage of wire harnesses with different lengths can be realized by changing the distance between the two wire clamping assemblies 3 at both ends. Moreover, the wire clamping assembly 3 can also rotate outside the mounting sleeve 1 through the outer sleeve 2. When the wire harness is too long, the wire harness can be spirally wound around the outside of the first sleeve 7 and the second sleeve 8 by rotating the outer sleeve 2 to prevent the wire harness from becoming loose. At the same time, the wire clamping assembly 3 is connected to the locking member 27 provided outside the outer sleeve 2 through the connecting member 28. The setting of the locking member 27 enables the locking column 46 provided at the end of the connecting member 28 to be locked only by simple pushing, and the locking of the locking column 46 can be released only by pushing again later. Thus, the rapid disassembly of the wire clamping assembly 3 can be realized, and it is also convenient for the rapid taking and placing of the wire harness during subsequent use.

[0064] Embodiment Two: Please refer to Figures 19-23, for the first embodiment, the thickness of the wire harnesses with different lengths will also be different. In order to enable the wire clamping assembly 3 to effectively clamp wire harnesses with different overall thicknesses, in this embodiment, the wire clamping assembly 3 includes a bottom ring 48 and a top ring 49. Between the bottom ring 48 and the top ring 49, there are several arc-shaped pieces 50. One end of the arc-shaped piece 50 is fixedly installed with a mounting shaft 51 towards one side of the top ring 49. There are several shaft holes 52 opened on the top ring 49. The mounting shaft 51 is rotatably installed in the shaft holes 52. On the side of the bottom ring 48 facing the top ring 49, there are several guide grooves 53 opened. One end of the arc-shaped piece 50 far from the mounting shaft 51 is fixedly installed with a sliding column 54 arranged towards the bottom ring 48. The sliding column 54 is slidably arranged in the guide groove 53. By externally rotating the top ring 49, the top ring 49 can drive the mounting shaft 51 to move synchronously through the shaft holes 52. The mounting shaft 51 then drives one end of the arc-shaped piece 50 to move, so that the arc-shaped piece 50 can move towards the center of the bottom ring 48 and the top ring 49. When the wire harness passes through the centers of the top ring 49 and the bottom ring 48, the moving arc-shaped piece 50 will contract and clamp the wire harness, thereby ensuring the stability of the wire harness. Moreover, the provided guide grooves 53 can also be adapted to the insertion rods 43, and then the bottom ring 48 is clamped by the positioning plate 45, so as to realize the stable assembly of the insertion plate 42 and the bottom ring 48.

[0065] In order to enable the bottom ring 48 and the top ring 49 to be stably assembled, in this embodiment, a first connecting block 55 is integrally arranged on the outer wall of the bottom ring 48. On the outer side of the side of the top ring 49 far from the bottom ring 48, there is a retaining edge 56. On the outside of the retaining edge 56, there is a pressing ring 57. On the outer side wall of the pressing ring 57, a second connecting block 58 is integrally arranged. The first connecting blocks 55 and the second connecting blocks 58 are in one-to-one correspondence and are oppositely arranged. The first connecting block 55 and the second connecting block 58 arranged oppositely are fixedly connected by a locking nail 59. A handle 60 is also fixedly arranged on the outer wall of the top ring 49.

[0066] Through the above scheme of the present invention, the wire clamping assembly 3 provided by the present invention uses the arc-shaped pieces 50 to achieve contraction and expansion. The synchronous contraction of multiple arc-shaped pieces 50 can effectively clamp and fix the ends of wire harnesses with different overall thicknesses. The process only requires a simple rotation of the top ring 49, and it is also very convenient and fast to pick up and place single wire harnesses subsequently.

[0067] Embodiment Three: For the first embodiment and the second embodiment, in order to better reflect the use effect of the above-mentioned automobile wire harness anti-tangling device, this embodiment also discloses a use method of the above-mentioned automobile wire harness anti-tangling device, including the following steps:

[0068] S1. Pass multiple wire harnesses of the same type with terminals crimped at the ends through the inside of the wire clamping assembly 3, and pass a fixed number of wire harnesses according to the specifications, and make the wire clamping assembly 3 close to the ends of the wire harnesses;

[0069] S2. Rotate the handle 60 to adjust the top ring 49 until the arc-shaped piece 50 moves towards the wire harness and stably clamps the wire harness.

[0070] S3. Move the connecting piece 28 outside the wire clamping assembly 3 towards the locking piece 27 until the locking post 46 is inserted into the outer housing 29 and locked.

[0071] S4. Rotate the adjusting handle 17 to adjust the length of the folding frame 9 until the entire wire harness is arranged in a straight line.

[0072] S5. If the folding frame 9 in S4 has reached the length critical value and the entire wire harness still does not present a straight line, pull out the positioning pin 20, rotate the outer sleeve 2 so that the entire wire harness is spirally wound around the outside of the first sleeve 7 and the second sleeve 8, then insert the positioning pin 20 into the positioning hole 19, and finally hoist the wire harness on the wire storage rack for standby through the lifting hook 5.

[0073] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0074] The wire clamping assembly 3 provided by the present invention can clamp both ends of the wire harness, so as to stably store the wire harness to be assembled. The wire clamping assembly 3 is also installed outside the mounting sleeve 1 through the outer sleeve 2, and the distance between the two wire clamping assemblies 3 can be adjusted through the folding frame 9. Therefore, when the lengths of the wire harnesses to be stored are different, the storage of wire harnesses of different lengths can be realized by changing the distance between the two wire clamping assemblies 3 at both ends. Moreover, the wire clamping assembly 3 can also rotate outside the mounting sleeve 1 through the outer sleeve 2. When the wire harness is too long, the outer sleeve 2 can be rotated to make the wire harness spirally wound around the outside of the first sleeve 7 and the second sleeve 8 to prevent the wire harness from loosening. At the same time, the wire clamping assembly 3 is connected to the locking piece 27 provided outside the outer sleeve 2 through the connecting piece 28. The setting of the locking piece 27 enables the locking of the locking post 46 provided at the end of the connecting piece 28 to be realized only by simple pushing, and the locking of the locking post 46 can be released only by pushing again later. Thus, the quick disassembly of the wire clamping assembly 3 can be realized, and it is also convenient for the quick picking and placing of the wire harness during subsequent use.

[0075] The wire clamping assembly 3 provided by the present invention uses the arc-shaped pieces 50 to realize contraction and expansion. The synchronous contraction of multiple arc-shaped pieces 50 can effectively clamp and fix the ends of wire harnesses with different overall thicknesses. The process only requires a simple rotation of the top ring 49, and it is also very convenient and fast when picking and placing single wire harnesses subsequently.
