AI Technical Summary
目前多是采用常规的U型叉固定连接器（将连接器上的线分开插在U型叉的一端），这样定位连接器在实际捆扎线束时需要将连接器从U型叉上取下来，然后工作人员依靠卷尺测量连接器距离线束需要捆扎位置的距离，然后进行捆扎，人工测量距离易出现测量和读数误差，而导致捆扎位置偏移，导致组装误差，故有待改进
该线束模块化组装定位工装，通过在U型叉上设置模具块，可以用来放置连接器，当将连接器放置在模具块的模槽内后，然后将连接线置于束线夹组件内，这样当需要捆扎连接器处的连接线时，因为事先确认好距离放置束线夹组件，束线夹组件上的束线猫头夹到连接器的距离长度就是需要捆扎的长度，即只需要将位于束线猫头夹位置处的连接线整合后捆扎即可，因为连接器不会移动，所以捆扎后的连接线不会出现明显长短不一的情况，也不需要将连接器取下，相比于现有技术中需要将连接器从U型叉上取下，同时将连接线从束线夹组件上取下，然后工作人员通过卷尺从连接器处测量连接线的长度，然后再对连接线测量好的位置进行捆扎来说更加的省时，提高了工作效率，而且不存在出现测量和读数误差而导致捆扎位置偏移，导致组装误差的情况。

Technical Field
[0001] This application relates to the field of wire harness assembly technology, and more specifically, to a modular assembly positioning tooling for wire harnesses. Background Technology
[0002] Automotive wiring harnesses have many branches and complex routing. When assembling wiring harnesses in a modular fashion, it is necessary to integrate multiple groups of wiring harnesses together. However, each group of wiring harnesses has a connector at its end. In order to facilitate the identification and use of each group of wiring harnesses later, all the wires on each group of wiring harnesses are usually bundled together at a certain distance from the connector (in actual bundling, the bundling will be carried out at a suitable distance from the connector according to the customer's order requirements). Currently, most connectors are fixed using a conventional U-shaped fork (the wires on the connector are separated and inserted into one end of the U-shaped fork). When actually bundling the wire harness, the connector needs to be removed from the U-shaped fork, and then the workers use a tape measure to measure the distance between the connector and the position where the wire harness needs to be bundled before bundling. Manual measurement of distance is prone to measurement and reading errors, which can lead to misalignment of the bundling position and assembly errors. Therefore, this method needs to be improved. Summary of the Invention
[0003] The purpose of this application is to provide a modular assembly and positioning tooling for wire harnesses to solve the problems mentioned in the background art.

The first magnetic base is magnetically connected to the positioning ring. The mold block has a mold groove on its top for placing a connector. Several connecting wires are connected to the connector. The mold block has two sockets, and the two ends of the U-shaped fork are inserted into the two sockets. The cable clip assembly is magnetically connected to the wiring board.

The two ends of the connecting block are respectively connected to the bottom of the first vertical block and the top of the second vertical block, and one end of the bottom block is connected to the bottom of the second vertical block.
[0006] Preferably, the bottom of the base block is provided with a second groove, and a second magnet is provided in the second groove. A calibration groove is provided in the middle of the other end of the base block. A third groove is provided on the side of the first vertical block near the mold block, and a third magnet is provided in the third groove. A first groove is provided in the middle of the side of the mold block near the first vertical block, and a first magnet is provided in the first groove. The first magnet and the third magnet are magnetically connected.
[0007] Preferably, the top of the upright is fixedly connected to the U-shaped fork, the top of the first magnetic base is fixedly connected to the first connecting cylinder, and the bottom of the upright is threadedly connected to the first connecting cylinder.
[0008] Preferably, the cable clip assembly includes a second magnetic base, a post, and a cable clip head; both ends of the post are detachably connected to the second magnetic base and the cable clip head, respectively.
[0009] Preferably, the cable tie clip includes a U-shaped base and two peach-shaped blocks. The U-shaped base has notches at both ends. The peach-shaped blocks include a tip and a base, with the base located in the notch. The upper and lower parts of the peach-shaped blocks are provided with arc-shaped grooves. A second pin is provided through the upper and lower parts of the notch. The middle parts of the two second pins pass through the two arc-shaped grooves respectively. A first pin is provided through the middle of the notch. The middle part of the base of the peach-shaped block is provided with a circular groove. The clip also includes a spring. One end of the spring is located in the circular groove and is connected and fixed to the inner wall of the circular groove. The other end of the spring is connected and fixed to the first pin.
[0010] Preferably, the bottom of the U-shaped base is fixedly connected to a threaded column, the top of the column is provided with a threaded groove, and the threaded column is threadedly connected in the threaded groove; the top of the second magnetic base is fixedly connected to a second connecting cylinder, and the bottom of the column is threadedly connected in the second connecting cylinder.
[0011] Compared with the prior art, the beneficial effects of this application are: This modular assembly and positioning fixture for wire harnesses uses a mold block on a U-shaped fork to hold the connector. After placing the connector in the mold slot, the connecting wire is then placed in the wire harness clamp assembly. When it's time to bundle the connecting wire at the connector location, the distance from the wire harness clip on the assembly to the connector is predetermined, meaning the bundled length is simply the length of the connecting wire at the clip's position. Since the connector doesn't move, the bundled connecting wires won't have noticeable length discrepancies, and there's no need to remove the connector. Compared to existing technologies that require removing the connector from the U-shaped fork and the connecting wire from the wire harness clamp assembly, then having workers measure the wire length using a tape measure before bundling, this method is much more time-efficient and improves work efficiency. Furthermore, it eliminates measurement and reading errors that could lead to bundling position deviations and assembly errors. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] This application provides a technical solution: A modular assembly and positioning fixture for wire harnesses, please refer to [link / reference]. Figures 1-6The wiring board 10 (only a partial schematic drawing, the actual wiring board will be larger) is made of iron. The wiring board 10 has several positioning rings 100, and some positioning rings 100 have guide lines 101 between them. The positioning rings 100 and the guide lines 101 can be lines laser-printed on the wiring board 10. U-shaped fork fixing component 20, the U-shaped fork fixing component 20 includes U-shaped fork 201, first magnetic base 202, and upright 200 connecting U-shaped fork 201 and first magnetic base 202. The first magnetic base 202 is magnetically connected to the positioning ring 100. Specifically, the top of the upright 200 is fixedly connected to the U-shaped fork 201, the top of the first magnetic base 202 is fixedly connected to the first connecting cylinder 203, and the bottom of the upright 200 is threadedly connected to the first connecting cylinder 203; the bottom of the first magnetic base 202 is provided with an installation groove, and a magnet block is glued in the installation groove, with the bottom of the magnet block flush with the bottom of the first magnetic base 202.
[0021] The cable clamp assembly 30 is magnetically connected to the wiring board 10. The cable clamp assembly 30 is located on the guide line 101 and is located on one side of the U-shaped fork fixing member 20 to limit the routing of the connecting line 51. Specifically, the cable clip assembly 30 includes a second magnetic base 302, a post 300, and a cable clip head clip; both ends of the post 300 are detachably connected to the second magnetic base 302 and the cable clip head clip, respectively.
[0022] Cable harness clips are a common cable harness structure used in automotive wiring harnesses and are considered standard technology. For ease of understanding, the following is a simplified explanation of cable harness clips: The cable clip includes a U-shaped base 304 and two peach-shaped blocks 305, with the tips of the two peach-shaped blocks 305 approximately abutting each other. Both ends of the U-shaped base 304 have notches 3040. Each peach-shaped block 305 includes a tip and a base, with the base located within the notch 3040. The upper and lower parts of each peach-shaped block 305 have arc-shaped grooves 3050. Second pins 309 are threaded through the upper and lower parts of each notch 3040, with the middle portions of the two second pins 309 passing through the two arc-shaped grooves 3050 respectively. A... The device includes a first pin 308, a circular groove at the base of the peach-shaped block 305, and a spring 307. One end of the spring 307 is located in the circular groove and is fixed to the inner wall of the circular groove. The other end of the spring 307 is fixed to the first pin 308. Specifically, both ends of the spring 307 are provided with connecting hooks, and the inner wall of the circular groove is provided with a hook groove. The connecting hook at one end of the spring 307 is located in the circular groove and hooked in the hook groove. The first pin 308 is provided with a hook groove, and the connecting hook at the other end of the spring 307 is hooked in the hook groove of the first pin 308.
[0023] It is worth noting that, without external force, the peach-shaped block 305 can be kept in an approximately horizontal state under the force of spring 307. At this time, the second pin 309 is a certain distance away from the inner wall of the arc-shaped groove 3050 near its base. When a downward force is applied to the tip of the peach-shaped block 305, it can rotate downward, and the arc-shaped groove 3050 can slide along the second pin 309. When the inner wall of the arc-shaped groove 3050 near its base abuts against the upper second pin 309, the peach-shaped block 305 can no longer rotate, and at this time, the tips of the two peach-shaped blocks 305 open. The connecting wire 51 can be placed inside the U-shaped seat 304. When the tip of the peach-shaped block 305 loses external force, the peach-shaped block 305 will return to its original position under the action of the spring 307. When it is necessary to remove the connecting wire 51 from the U-shaped seat 304, lift the connecting wire 51 upwards (it is worth noting that if the force applied to the peach-shaped block 305 when lifting the connecting wire 51 upwards is small, the peach-shaped block 305 will not rotate upwards). This will cause the peach-shaped block 305 to rotate upwards, opening the tips of the two peach-shaped blocks 305, and the connecting wire 51 can be removed from the U-shaped seat 304.
[0024] In the prior art, during modular assembly of the wire harness, the first magnetic seat 202 of the U-shaped fork fixing member 20 is placed inside the positioning ring 100. Depending on the assembly requirements, multiple U-shaped fork fixing members 20 may be needed (the number of U-shaped fork fixing members 20 corresponds to the number of wire harness groups). The connector 50 of each wire harness group is placed at the U-shaped fork fixing member 20. To facilitate subsequent identification and use of each wire harness group, all wires in each group are typically bundled together at a distance from the connector (in actual bundled bundling, the appropriate distance from the connector is chosen based on customer order requirements). Depending on actual needs, a wire harness clip assembly 30 is magnetically connected to the guide wire 101 on the wiring board 10 at an appropriate distance from each U-shaped fork fixing member 20. Figure 6 As shown, the connecting wires 51 on the connector 50 will be randomly separated and placed on one end of the U-shaped fork 201; then the connecting wires 51 will be placed inside the cable tie assembly 30. This will determine the position where the connecting wires 51 on each group of connectors 50 need to be bundled (i.e., the connecting wires 51 are located at the position of the cable tie assembly 30). Because in the existing technology, the connecting wires 51 on the connector 50 are randomly separated and placed on one end of the U-shaped fork 201, the position of the connector 50 is prone to rotation and displacement. Furthermore, when the randomly separated connecting wires 51 on both sides of the U-shaped fork 201 are bundled together, the lengths of the connecting wires 51 on both sides are easily uneven. Therefore, in actual bundling, the connector 50 needs to be removed from the U-shaped fork 201, and the connecting wires 51 need to be removed from the cable tie assembly 30. Then, the operator needs to measure the length of the connecting wires 51 from the connector 50 using a tape measure, and then bundle the connecting wires 51 at the measured position. This measurement and bundling process is time-consuming, and the connecting wires 51 need to be put back into the cable tie assembly 30, and the connector 50 needs to be placed back on the U-shaped fork 201. In addition, manual measurement is prone to measurement and reading errors, leading to bundling position deviations and assembly errors. Therefore, this application designs a mechanism that can position the connector 50 to prevent the connector 50 from moving on the U-shaped fork 201 during bundling; the details are as follows: A mold block 40 is provided, and a mold groove 400 is provided on the top of the mold block 40. The mold groove 400 is used to place the connector 50. In actual use, the mold groove 400 of each mold block 40 is designed according to the shape of different connectors 50. When the connector 50 is placed into the mold groove 400 from above, the connector 50 cannot move horizontally in the front-back, left-right and right directions within the mold groove 400. The mold block 40 is made of plastic material made from a 3D printed model. Several connecting wires 51 are connected to the connector 50. The mold block 40 is provided with two insertion holes 401. The two ends of the U-shaped fork 201 are inserted into the two insertion holes 401. The mold block 40 is inserted into the U-shaped fork 201 until it can no longer be pressed down. After the connector 50 is placed in the mold slot 400 of the mold block 40, the connecting wire 51 is placed in the cable tie assembly 30. When it is necessary to bundle the connecting wire 51 at the connector 50, since the distance of the cable tie assembly 30 is determined in advance, the distance from the cable tie clip on the cable tie assembly 30 to the connector 50 is the length to be bundled. That is, it is only necessary to bundle the connecting wire 51 located at the position of the cable tie clip. Since the connector 50 will not move, the bundled connecting wire 51 will not have obvious uneven lengths, and it is not necessary to remove the connector 50. Compared with the existing technology, which requires removing the connector 50 from the U-shaped fork 201 and the connecting wire 51 from the cable tie assembly 30, and then the worker measuring the length of the connecting wire 51 from the connector 50 with a tape measure before bundling the connecting wire 51 at the measured position, no additional measurement with a tape measure is required, which improves work efficiency.
[0025] The bottom of the U-shaped base 304 is fixedly connected to a threaded post 306, and the top of the post 300 is provided with a threaded groove 301, in which the threaded post 306 is threadedly connected; the top of the second magnetic base 302 is fixedly connected to a second connecting cylinder 303, and the bottom of the post 300 is threadedly connected to the second connecting cylinder 303; the bottom of the second magnetic base 302 is provided with an installation groove, in which a magnet block is bonded, and the bottom of the magnet block is flush with the bottom of the second magnetic base 302.
[0026] Because in the prior art, the connecting wires 51 on the connector 50 are randomly placed on one end of the U-shaped fork 201, during wire harness assembly, the connecting wires 51 are often subjected to tension, causing the connector 50 to rotate the U-shaped fork 201, resulting in the entire U-shaped fork fixing member 20 shifting in position. This requires workers to put the U-shaped fork fixing member 20 back into its original positioning ring 100. However, when placing the U-shaped fork fixing member 20, it is necessary to align it with the wire harness clamp assembly 30 (i.e., the orientation of the U-shaped fork fixing member 20 needs to be aligned with the guide line 101), which is quite time-consuming. To facilitate faster alignment of the U-shaped fork fixing member 20 with the wire harness clamp assembly 30, this application also designs the following technical solution: It also includes a calibration component 60, which is used to adjust the U-shaped fork retainer 20 to quickly align with the cable clamp assembly 30; for details, please refer to [link / reference]. Figure 3 The calibration component 60 includes a first vertical block 600, a second vertical block 601, a connecting block 602, and a bottom block 603. The two ends of the connecting block 602 are connected to the bottom of the first vertical block 600 and the top of the second vertical block 601, respectively. One end of the bottom block 603 is connected to the bottom of the second vertical block 601. The first vertical block 600, the second vertical block 601, the connecting block 602, and the bottom block 603 are all made of plastic material using a 3D printed model.
[0027] The bottom of the base block 603 is provided with a second groove, and a second magnet block 605 is bonded to the second groove. The bottom of the second magnet block 605 is flush with the bottom of the base block 603. The other end of the base block 603 is provided with a calibration groove 604. The first vertical block 600 is provided with a third groove on the side near the mold block 40. A third magnet block 606 is bonded to the third groove. The third magnet block 606 is flush with the side of the first vertical block 600 near the mold block 40. The mold block 40 is provided with a first groove in the middle of the side near the first vertical block 600. A first magnet block 402 is bonded to the first groove. The first magnet block 402 is flush with the side of the mold block 40 near the first vertical block 600. The first magnet block 402 and the third magnet block 606 are magnetically connected.
[0028] When the second magnet block 605 inside the bottom block 603 is magnetically attracted to the wiring board 10, the top height of the first vertical block 600 is lower than or equal to the height of the bottom of the inner wall of the mold groove 400.
[0029] This allows the third magnet 606 on the first vertical block 600 to be magnetically connected to the first magnet 402 on the mold block 40. Then, the second magnet 605 in the bottom block 603 is magnetically attracted to the wiring board 10, and the magnet at the bottom of the first magnetic seat 202 is magnetically attracted to the wiring board 10. By rotating the calibration assembly 60 and the U-shaped fork fixing member 20 as a whole, the calibration groove 604 on the calibration assembly 60 is aligned with the guide line 101 facing the cable clamp assembly 30, thus achieving the alignment of the U-shaped fork fixing member 20 with the cable clamp assembly 30.
[0030] Of course, in actual wire harness assembly, in addition to the wire harness clamp assembly 30 located at the U-shaped fork fixing part 20 for bundling, other wire harness clamp assemblies 30 will also be provided to facilitate the routing of connecting wires on multiple wire harnesses.
