Description

Technical Field

[0001] The present invention belongs to the technical field of cable length control, and in particular relates to a device and method for controlling the length of a small and complex cable. Background Art

[0002] As equipment develops towards miniaturization and increased functionality, the cables used in these devices are also becoming smaller and more complex. Micro-compact cables have become a trend. The short branch lengths and complex shapes of these cables make their manufacture difficult. Furthermore, their suitability for installation and assembly is poor, often resulting in defects such as excessive short branch lengths and interference between cable branches after installation.

[0003] Traditional cable assembly methods pre-fabricate short branches and difficult-to-make connectors based on their installation orientation. After fabrication, the cables are then bundled using a tape measure to measure the length of the branches, based on the cable outline dimensions and wiring orientation. For flat branches, this is achieved by continuously measuring their length and width and bundling the conductors according to their orientation. Existing cable length control technologies also fail to address issues such as out-of-tolerance short branch lengths and interference after laying of partial branches during cable assembly manufacturing.

[0004] For example, the patent document with publication number CN220591420U specifically discloses a device for batch cutting cables to a fixed length, which relates to the field of cable cutting technology. The device comprises a base, a mounting plate fixedly provided on the base, a turntable rotatably provided on one side of the mounting plate, a plurality of winding rods slidingly provided on one side of the turntable, the distance between the plurality of winding rods and the central axis of the turntable being adjustable, a rotating drum for mounting the cable drum rotatably provided on one side of the mounting plate, a fixed frame fixedly provided on the base, a telescopic rod fixedly provided above the fixed frame, a cutter fixedly provided at the telescopic end of the telescopic rod, the height of the cutter being equal to the height of the central axis of the turntable. This technical solution can wind multiple turns of cable by providing a winding rod, and then the multiple turns of cable can be cut simultaneously by the cutter, thereby obtaining multiple single-segment cables of equal length. This patented technology solves the problem of automatic cutting of the length of finished cables, but does not solve the problem of length control during the production of cable assemblies, and this patented technology is complex to operate.

[0005] In summary, the existing technical solutions have the following technical problems: the length of short branches within 30mm of small and complex cables (hereinafter referred to as ultra-short branches) needs to be repeatedly measured to determine whether they meet the requirements; the width and length of flat cable branches need to be repeatedly measured; the production cycle is long and the operation is complicated.

[0046] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0047] The embodiment of the present invention provides a device and method for controlling the length of small and complex cables to solve the technical problems that the length of ultra-short branches of small and complex cables needs to be repeatedly measured to determine whether they meet the requirements, the width and length of flat cable branches need to be repeatedly measured, the production cycle is long, and the operation is complicated. Figure 1 -Attached Figure 14 The specific implementation of the present invention is described in detail.

[0048] like Figures 1-14 As shown, an embodiment of the present invention provides a device for controlling the length of small, complex cables, comprising an ultra-short branch control module 1, a flat branch control module 2, and a welding fixture 3. The flat branch control module 2 is open at one end and closed at the other. The open end is connected to the welding fixture 3 via a connecting block 6, and the closed end is connected to the ultra-short branch control module 1 via screws. Fixed brackets A4 and B5 are symmetrically provided on either side of the ultra-short branch control module 1. The arrangement of the ultra-short branch control module 1, the flat branch control module 2, and the welding fixture 3 enables length control of segments of ultra-short branches, flat branches, and complex branches to be welded, with simple operation.

[0049] In this embodiment, a through slot A11 is provided on the upper surface of the ultra-short branch control module 1. On either side of the through slot A11 are a wide and a narrow boss. A mounting platform 13 is provided on the through slot A11. On either side of the mounting platform 13 are provided a connector mounting cavity A14 for mounting the XA connector 9 and a connector mounting cavity B15 for mounting the XB connector 10. The mounting platform 13, the boss, and the upper surface of the flat branch control module 2 are on the same horizontal plane. By setting up the above structure, the ultra-short branch XA connector 9 and the XB connector 10 of the cable can be fixed and the direction can be controlled, and the ultra-short branch of the cable can be fixed, and the length can be controlled and inspected. In addition, considering the working conditions, the ultra-short branch control module 1 should be made of non-metallic materials with a smooth and flat surface that will not damage the cable bundle; according to functional requirements. The distance between the connector installation cavity A14 and the connector installation cavity B15 should be the same as the distance between the two branches after the cable is laid. According to the shape and laying requirements of the cable, the length of the ultra-short branch should be the same as the distance between the XA connector 9 and the XB connector 10 to the flat cable segment. Considering the thickness requirements of the flat branch segment, the ultra-short branch control module 1 is symmetrically provided with four mounting holes on the upper surface of both sides of the through slot A11 for installing the thickness control device 24. The ultra-short branch control module 1 after installing the XA connector 9 and the XB connector 10 is as shown in FIG. Figure 12 shown.

[0050] In this embodiment, a through slot B12 is provided on the lower surface of the ultra-short branch control module 1, and the through slot B12 is perpendicular to the opening direction of the through slot A11. The connector mounting cavity A14 and the connector mounting cavity B15 connect the through slot A11 and the through slot B12. The width of the through slot B12 is greater than the length of the connector mounting cavity A14, which facilitates the installation of the XA connector 9 and the XB connector 10.

[0051] In this embodiment, the upper end of the fixed bracket B5 has the same shape as the inclined surface of the ultra-short branch control module 1, and a through groove C16 is vertically provided on the side that contacts the wide boss of the ultra-short branch control module 1. The through groove C16 is used to install the side bracket 7. The side bracket 7 mainly plays a role in strengthening support and is mainly used to support the welding of the XA connector 9 and the XB connector 10. After assembly, the side bracket 7 can move freely. When welding the XC connector in the welding fixture 3, the side bracket 7 is placed on its side to enhance the support capacity of the entire device; the fixed bracket B5 is as shown in FIG. Figure 13 shown.

[0052] In this embodiment, fixed brackets A4 and B5 are mirror images. To enhance the stability of the ultra-short branch control module 1 and coordinate with the height of the flat branch control module 2 and welding fixture 3, the vertical distance from the highest point of fixed brackets A4 and B5 after installation to the ground matches the length of the legs 23 of the flat branch control module 2. Based on portability and the balance of the overall device structure, a height of 75 mm is preferred. Considering operating conditions, the ultra-short branch control module 1 is constructed from commonly used lightweight metal materials with a smooth, flat surface that will not damage the cable harness.

[0053] In this embodiment, the raised lower surfaces on both sides of the open end of the flat branch control module 2 are provided with square grooves 21 for installing and storing the legs 23. The square grooves 21 are provided with square holes 22 connecting the upper and lower surfaces of the flat branch control module 2 toward the tail of the closed end. The flat branch control module 2 mainly controls and inspects the width, length and thickness of the flat branch. It is mainly used to control the width, length and thickness of the flat branch segment cable and to inspect the width, length and thickness of the flat branch segment. Considering the working conditions, the control module should be made of non-metallic materials with a smooth and flat surface that will not damage the cable bundle. According to functional requirements, the width of the control part of the flat branch control module 2 is the same as the width of the flat branch of the cable; the length of the control part of the flat branch control module 2 is the same as the length of the flat branch of the cable; the design of the square grooves 21 and the square holes 22 makes the use and storage of the legs 23 more convenient and easy. The height of the legs 23 when in use is consistent with the vertical distance from the highest point of the fixed bracket A4 and the fixed bracket B5 to the ground after installation. When not in use, they can be stored in the square grooves 21. The flat branch control module 2 is as shown Figure 5-6 shown.

[0054] In this embodiment, the welding fixture 3 includes a bottom plate 31, a top plate 32, an opening and closing device, a connector mounting cavity C37 and a guide rod 35. The top plate 32 is arranged on the bottom plate 31, the opening and closing device is arranged at the connection between the bottom plate 31 and the top plate 32, and the connector mounting cavity C37 is arranged on the side of the welding fixture 3 facing away from the opening and closing device. The guide rod 35 passes through the top plate 32 and connects to the bottom plate 31. The guide rod 35 is partially sleeved with a spring 36 on the top plate 32, and the side of the bottom plate 31 is connected to the connecting block 6 by screws. The main function of the welding fixture 3 is to achieve the fixation of connectors with short cable branch lengths and high welding difficulty, facilitating welding. In addition, the welding fixture 3 is assembled together with the ultra-short branch control module 1 and the flat branch control module 2. By controlling the assembly position in the length direction, the cable branch length of the XC connector can also be controlled. The top plate 32 opens and closes along the guide rod 35. The top of the guide rod 35 is a threaded rod for easy assembly, and the tail end is a smooth rod for easy sliding of the top plate 32 along the guide rod 35. The guide rod 35 passes through the top plate 32 and is fastened to the screw hole of the bottom plate 31. It can clamp the XC connector together with the top plate 32. Aluminum alloy is selected to reduce weight. The spring 36 is used to press the top plate 32 so that the XC connector is pressed into the connector installation cavity C37 after installation. The opening and closing device is pushed to control the position of the top plate 32 and the bottom plate 31 to open and close the connector installation cavity C37. When opening, the XC connector is placed, and when closing, the XC connector is fixed. The welding fixture 3 is as shown in FIG. Figure 7-11 shown.

[0055] In this embodiment, the opening and closing mechanism includes an upper push rod 33 and a lower push rod 34. The upper push rod 33 is fixed to the bottom plate 31, and the lower push rod 34 is fixed to the top plate 32. The upper push rod 33 is inserted through the middle of the lower push rod 34. The upper push rod 33 and the lower push rod 34 are both L-shaped members with their curved portions facing each other. The top plate 32 and the bottom plate 31 are opened by pushing the upper push rod 33 and the lower push rod 34 simultaneously, and closed by the force of the spring 36.

[0056] In this embodiment, the device for controlling the length of a small and complex cable further includes a thickness control device 24. The thickness control device 24 is mounted on the upper surface of the ultra-short branch control module 1 and the flat branch control module 2. The inner width of the thickness control device 24 is greater than the width of the mounting platform 13. The mounting position of the thickness control device 24 on the flat branch control module 2 corresponds to the mounting position on the ultra-short branch control module 1. After installation, it can be determined whether the thickness of the cable meets the use requirements; the thickness control device 24 is as follows: Figure 14 shown.

[0057] In an embodiment of the present invention, a method for controlling the length of a small complex cable is provided, wherein the cable length is controlled in sections according to the characteristics of the cable, including the following steps:

[0058] Ultra-short branch length control: To control the length of the ultra-short branch cable, secure the XA connector 9 to the connector mounting cavity A14 and the XB connector 10 to the connector mounting cavity B15. First, crimp and pot the XA connector 9. Then, crimp the cable harness 8 not connected to the XA connector 10. Next, crimp and pot the cable harness 8 from XA to XB. When crimping the cable harness 8 from XA to XB, first align and secure the XA connector 9 and XB connector 10 to the corresponding branch section of the tooling according to the orientation indicated on the ultra-short branch control module 1. The ultra-short branch refers to a cable harness 8 less than 30 mm in length. The XA connector 9 may be a J30J-37ZK connector, and the XB connector 10 may be a J30J-9Z connector.

[0059] Flat branch control: After completing the ultra-short branch length control, keep the XA connector 9 and the XB connector 10 fixed on the tooling, and arrange the cable harness 8 according to the right side of the flat branch control module 2 and then tie the wires. The width of the ties is smaller than the inner cavity width of the thickness control device 24 to ensure that the width of the flat section meets the requirements. The spacing of the ties is marked on the upper surface of the flat branch control module 2 according to the binding requirements to avoid constant measurement with a ruler. The length of the flat branch control ends at the end of the flat branch control module 2; during the flat branch binding process or after the binding is completed, use the thickness control module 24 to measure the thickness to ensure that the thickness of the compiled flat section meets the requirements.

[0060] Control of the branch to be welded: After completing the flat branch control, fix the XC connector of the branch to be welded on the connector mounting cavity C37 of the welding fixture 3, and then perform welding control on the branch to be welded on the welding fixture 3. Its length is determined by the position of the welding fixture and does not need to be measured separately.

[0061] Control of other branches: When making connectors for other branches, measure the length of the cable conductors in advance, cut them to the required length, and then weld or crimp the connectors.
