Description

Technical Field

[0001] This application relates to the field of cable terminal crimping technology, and in particular to a cable terminal crimping device. Background Technology

[0002] Cable terminals are the interface parts for connecting or branching wires and cables, and they play a vital role in electrical engineering.

[0003] When using crimping tools to crimp terminals, specifically when using a crimping device to crimp cables onto cable terminals, it is necessary to control and determine the crimping depth, the length of the wire or cable conductor that is gripped by the terminal, which is usually the exposed length of the wire. An appropriate crimping depth can ensure close contact between the terminal and the wire and improve the efficiency of current conduction.

[0004] There are various types of cable terminals on the market, which are widely used in electrical connections such as motors, transformers, and shielded cables. Different terminals and wire specifications require the use of corresponding crimping tools and molds.

[0005] Existing crimping devices require different crimping tools for different types of cable terminals. Users place the cable conductor at the designated position on the cable terminal and insert the cable terminal with the cable into the crimping tool. The cable terminal and cable are then crimped together using pneumatic methods. However, this crimping method requires waiting for a sensor to detect whether the positioning is qualified after the cable terminal is placed and positioned, and then the pneumatic structure will respond. This waiting time is relatively long. In addition, multiple crimping devices need to be set up simultaneously for crimping different cable terminals, which increases costs. Summary of the Invention

[0006] This application provides a cable terminal crimping device that solves the problem that existing methods require multiple crimping devices for different cable terminals, resulting in high costs and slow response.

[0007] The technical solution of this application is as follows: A cable terminal crimping device for crimping a cable into a cable terminal, comprising:

[0008] A foldable base, comprising a vibrating plate and a fixed plate, wherein the vibrating plate and the fixed plate are rotatably connected on one side by a hinge, and an elastic element is provided above the fixed plate;

[0009] A crimping device, which is fixedly mounted on the base, is used to crimp the cable terminal;

[0010] A swing arm structure, one end of which is rotatably mounted on the upper end of the crimping device, and the other end extends to the outside of one side of the crimping device.

[0011] A drive structure is mounted on one side of the upper end of the fixed plate and located above the other end of the swing arm structure. It is used to drive the swing arm structure to swing and to drive the pressing device to perform pressing.

[0012] A retractable straightening structure, one end of which is rotatably mounted on the vibrating plate, and the other end of which is rotatably connected to the other end of the swing arm structure.

[0013] A positioning element, which is detachably mounted on the crimping device, is used to position the cable terminal.

[0014] By adopting the above scheme, the device can select matching positioning parts according to different types of cable terminals and assemble them on the crimping device. The drive structure drives the swing arm structure to swing, thereby driving the crimping device to crimp the cable terminals to the cables. The device can position and crimp different types of cable terminals, saving costs. At the same time, the direct drive method of the control drive structure avoids the positioning detection and response process, resulting in higher crimping efficiency. In addition, when the drive structure drives the swing arm structure to swing, it can also drive the vibrating plate to press against the fixed plate. After the crimping is completed, the vibrating plate rebounds quickly under the action of the elastic element. The vibration effect during the rebound facilitates the quick separation of the crimped terminal from the positioning part.

[0015] In one embodiment of this application, the crimping device includes:

[0016] A crimping seat is fixedly mounted on the upper end of the vibration plate;

[0017] A crimping ring is fitted into one side of the upper end of the crimping seat. An annular mating groove is formed between the outer edge of the crimping ring and the crimping seat. The crimping ring is used to crimp the cable terminal so that the cable terminal is crimped onto the cable.

[0018] An annular rotating groove is provided on the other side of the upper end of the pressing seat, and the annular rotating groove is concentric with the mating groove.

[0019] In one embodiment of this application, the crimping ring includes:

[0020] A fixing ring is fitted into one side of the upper end of the crimping seat. The outer edge of the fixing ring is provided with four expansion grooves at intervals, and the four expansion grooves are equidistantly distributed along the circumference of the fixing ring.

[0021] A mating block, one end of which is embedded in the telescopic groove and slidably connected to the telescopic groove, and the other end of which has an arc surface and extends to the outside of the fixing ring;

[0022] A movable rod, one end of which is fixedly mounted on one end of the mating block, and the other end extends toward the center of the fixed ring and passes through the fixed ring. A telescopic spring is sleeved on the outside of the movable rod. One end of the telescopic spring is connected and fixed to one end face of the mating block, and the other end is connected and fixed to the bottom wall of the telescopic groove.

[0023] An extrusion block is mounted on the other end of the moving rod.

[0024] By adopting the above scheme, the swing arm structure drives the mating blocks set on the fixed ring to perform synchronous extrusion, thereby enabling the mating blocks to drive the extrusion blocks to extend synchronously and uniformly crimp the cable terminals located at the center of the four extrusion blocks, so as to ensure the accuracy of crimping.

[0025] In one embodiment of this application, the positioning element includes:

[0026] A positioning stud is threaded onto the upper end of the crimping seat and is concentric with the annular rotating groove and the mating groove. A positioning groove is provided at the end of the positioning stud near the extrusion block. The positioning groove is adapted to the crimping terminal so that the crimping terminal enters the positioning groove to achieve positioning.

[0027] A lever, which is mounted on the other end of the positioning bolt.

[0028] By adopting the above solution and using a positioning stud that is threadedly connected to the crimping seat, positioning studs with different positioning grooves can be selected when facing different types of crimping terminals. The positioning stud that is compatible with the crimping terminal is screwed into the center of the crimping seat to realize the crimping of the device.

[0029] In one embodiment of this application, the swing arm structure includes:

[0030] The first arm plate is disposed on one side of the upper end of the pressing seat. A mating ring is fixedly connected to one end of the first arm plate near the pressing seat. The mating ring rotates in the mating groove. The inner edge of the mating ring is distributed with four mating gaps that correspond one-to-one with the positions of the four mating blocks along the circumferential direction of the mating ring.

[0031] The second arm plate is disposed on the other side of the crimping seat. A rotating ring is fixedly connected to one end of the second arm plate near the crimping seat. The rotating ring is rotatably assembled in the annular rotating groove.

[0032] A connecting shaft, the two ends of which are respectively connected and fixed to the first arm plate and the second arm plate;

[0033] A roller is rotatably mounted between the first arm plate and the second arm plate, with the upper end of the roller protruding from the first arm plate and the second arm plate.

[0034] By adopting the above scheme, when controlling the operation of the crimping device, the swing of the swing arm structure allows the mating rings to cooperate with each other, so that the swing arm structure can simultaneously squeeze the four mating blocks when rotating and swinging. The mating blocks drive the squeezing blocks to squeeze the cable terminals, thereby realizing the crimping of the cable terminals.

[0035] In one embodiment of this application, a circular through hole is provided at one end of both the first arm plate and the second arm plate, and the circular through hole is concentric with the crimping ring.

[0036] By adopting the above solution, circular through holes concentric with the crimping ring are opened on the first arm plate and the second arm plate, which makes it convenient for the user to pass the cable terminal through the circular through hole on the first arm plate for crimping the cable terminal, or to remove the positioning member from the circular through hole on the second arm plate.

[0037] In one embodiment of this application, the cable terminal crimping device further includes a coil spring, which is concentrically disposed outside the mating ring. One end of the coil spring is connected and fixed to the outer edge of the mating ring, and the other end is connected and fixed to the inner wall of the mating groove.

[0038] By adopting the above solution, after the swing arm structure receives external traction and swings, the coil spring retracts. After the pressing is completed, it can automatically return to the correct position under the elastic force of the coil spring, which facilitates the next pressing operation.

[0039] In one embodiment of this application, the driving structure includes:

[0040] A support frame, which is fixedly assembled onto the fixing plate;

[0041] A cylinder, which is fixedly mounted on the vertical frame in the vertical direction;

[0042] A push rod, one end of which is fixedly connected to the drive shaft of the cylinder and extends and retracts vertically under the drive of the cylinder.

[0043] By adopting the above solution, when driving the swing arm structure, the cylinder drives the push rod to press down on the other end of the swing arm structure, thereby causing the swing arm structure to swing, so as to drive the crimping device to crimp the cable terminal, thus improving the working efficiency of the device during crimping.

[0044] In one embodiment of this application, the straightening structure includes:

[0045] The first expansion joint, one end of which is rotatably mounted on the vibration plate via a rotating shaft;

[0046] The second expansion joint has one end coaxially inserted into the first expansion joint and slidably connected to the first expansion joint, and the other end rotatably connected to the connecting shaft.

[0047] A columnar spring is sleeved on the second telescopic joint, with one end of the columnar spring connected and fixed to the second telescopic joint and the other end connected and fixed to the first telescopic joint.

[0048] By adopting the above scheme, by setting up a first and second telescopic joint that can elastically extend and retract, and rotatably connecting them to the other end of the swing arm structure, the first and second telescopic joints rebound under the elastic force of the columnar spring after the swing arm structure swings, thereby improving the return speed of the swing arm structure.

[0049] In one embodiment of this application, the cable terminal crimping device further includes a limiting post, which is fixedly mounted on the crimping seat and located below the swing arm structure.

[0050] By adopting the above solution, and by setting a limiting post at a designated position, when the swing arm structure is swung to its lowest point by the drive structure, the limiting post can stop the swing arm structure from continuing to swing, thereby avoiding the situation where the swing arm structure cannot rebound smoothly due to excessive swing angle.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. By employing detachable positioning components, the device can accurately position different types of crimped terminals by easily replacing the positioning components, thus improving the applicability of the device.

[0053] 2. By using a drive structure to drive the swing arm structure to swing, after the crimping terminal and the positioning component are positioned, the drive structure can be directly activated to drive the swing arm structure to swing, thereby driving the extrusion block inside the crimping device to extend synchronously and perform crimping work on the crimping terminal. This eliminates the need to sense the crimping terminal and drive the pneumatic component to move, making the workflow simpler and the crimping efficiency higher.

[0054] 3. By setting up a vibrating plate and a fixed plate, after the drive structure drives the swing arm structure to swing to the lowest point, it simultaneously drives the vibrating plate to press against the fixed plate and complete the pressing work. After the pressing work is completed, the elastic element can lift the vibrating plate to a certain angle under its own elastic force, so that the vibrating plate vibrates on the fixed plate, and thus the entire pressing device vibrates continuously, which makes it convenient for the pressing terminals set inside the pressing device to quickly disengage from the positioning element.

[0064] The following is in conjunction with the appendix Figure 1-8 The present application provides a further detailed description of a cable terminal crimping device.

[0065] Please see Figure 1 This application provides a cable terminal crimping device for crimping cables into cable terminals 8. It includes: a base 1, a crimping device 2, a swing arm structure 3, a drive structure 5, a straightening structure 4, and a positioning element 6. The base 1 is foldable and includes a vibrating plate 12 and a fixed plate 11. The vibrating plate 12 and the fixed plate 11 are rotatably connected on one side via a hinge. Alternatively, the vibrating plate 12 and the fixed plate 11 can be rotatably connected on one side via a rotating shaft. An elastic element 13 is provided above the fixed plate 11, which can be an elastic metal protrusion or a rubber protrusion. The crimping device 2 is fixedly mounted on the base 1 and used to crimp the cable terminal. The swing arm structure 3 has one end rotatably mounted on the upper end of the crimping device 2 and the other end extending to the outside of one side of the crimping device 2 for driving the crimping device 2 to perform crimping. The drive structure 5... Structure 5 is mounted on one side of the upper end of the fixed plate 11 and located above the other end of the swing arm structure 3. It is used to drive the swing arm structure 3 to swing. The straightening structure 4 is telescopic. One end of the straightening structure 4 is rotatably mounted on the vibration plate 12, and the other end is rotatably connected to the other end of the swing arm structure 3. The positioning member 6 is detachably mounted on the crimping device 2 and is used to position the cable terminal 8. By setting different types of positioning members 6 and setting the positioning members 6 on the crimping device 2, the device can position different types of cable terminals 8. After the cable terminal 8 is manually positioned on the positioning member 6, the swing arm structure 3 is directly driven to swing through the drive structure 5 to complete the crimping work. The structure is simple, the response is fast, and the work efficiency is higher. At the same time, after the crimping is completed, the base 1 can return to the straightening position of the swing arm structure 3 and rely on inertial vibration to facilitate the cable terminal 8 to detach from the positioning member 6.

[0066] Please see Figure 2 , Figure 3 and Figure 4 The crimping device 2 includes a crimping seat 21, a crimping ring 23, and an annular rotating groove 24. The crimping seat 21 is fixedly mounted on the upper end of the vibrating plate 12. The crimping ring 23 is embedded in one side of the upper end of the crimping seat 21. An annular mating groove 22 is formed between the outer edge of the crimping ring 23 and the crimping seat 21. The crimping ring 23 is used to crimp the cable terminal 8, so that the cable terminal 8 is crimped onto the cable. The annular rotating groove 24 is located on the other side of the upper end of the crimping seat 21. The annular rotating groove 24 is concentric with the mating groove 22. By cooperating with the swing arm structure 3, the swinging motion of the swing arm structure 3 is converted into the circumferential crimping motion of the crimping ring 23 on the cable terminal 8, which enables the cable terminal 8 to be crimped quickly and efficiently.

[0067] The crimping ring 23 includes a fixing ring 231, a mating block 232, and a pressing block 233. The fixing ring 231 is embedded in the upper side of the crimping seat 21. The outer edge of the fixing ring 231 is provided with four telescopic grooves 2311 at intervals. The four telescopic grooves 2311 are equidistantly distributed around the circumference of the fixing ring 231. One end of the mating block 232 is embedded in the telescopic groove 2311 and slidably connected with the telescopic groove 2311. The other end is provided with an arc surface 2321 and extends to the outside of the fixing ring 231. One end of the moving rod 234 is fixedly mounted on one end of the mating block 232, and the other end extends toward the center of the fixing ring 231 and passes through the fixing ring 231. A telescopic spring 2341 is sleeved on the outside of the moving rod 234. One end of the telescopic spring 2341 is connected to the mating block 232. One end face of block 232 is fixed, and the other end is fixed to the bottom wall of the telescopic groove 2311. The pressing block 233 is assembled on the other end of the moving rod 234. The distance of the arc surface 2321 of the mating block 232 extending to the outside of the fixed ring 231 can be converted into the distance of movement of the pressing block 233. Therefore, the device can customize the distance of the arc surface 2321 of the mating block 232 extending to the outside of the fixed ring 231 according to the actual working conditions. Under the rotation of the swing arm structure 3, the pressing block 233 can press the cable terminal 8 after the mating block 232 retracts into the telescopic groove 2311, deform it and fasten it to the cable conductor, so as to realize the crimping of the cable and the cable terminal 8.

[0068] In other embodiments, the number of expansion grooves 2311 can also be set to six or other even numbers. Similarly, the number of mating blocks 232 and pressing blocks 233 can be set to six or other even numbers in sync with the expansion grooves 2311. According to the crimping requirements of different cable terminals 8, different numbers of pressing blocks 233 are selected to press the crimping terminals 8 to complete the crimping work between the cable and the cable terminal 8.

[0069] Please see Figure 6The positioning component 6 includes a positioning stud 61 and a lever 62. Multiple positioning studs 61 can be provided, each customized to correspond to different types of cable terminals 8. The positioning stud 61 is threaded onto the upper end of the crimping seat 21 and is concentric with the annular rotating groove 24 and the mating groove 22. A positioning groove 611 is formed at the end of the positioning stud 61 near the pressing block 233. The positioning groove 611 is adapted to the crimping terminal 8, allowing the crimping terminal 8 to enter the positioning groove 611 for positioning. The lever 62 is mounted on the positioning... On the other end of the positioning bolt 61, multiple positioning elements 6 are provided, each adapted to different types of cable terminals 8. Each positioning element 6 is provided with a positioning groove 611 that matches the shape of the end of the cable terminal 8. Different types of positioning grooves 611 can be customized according to the crimping requirements of the corresponding cable terminal 8, including but not limited to parameters such as shape, depth and width. This allows the device to perform crimping work on different types of crimping terminals 8 by replacing the positioning studs 61 with different types of positioning grooves 611.

[0070] Please see Figure 2 and Figure 3 The swing arm structure 3 includes: a first arm plate 31, a second arm plate 32, a connecting shaft 33, and a roller 34. The first arm plate 31 is disposed on one side of the upper end of the pressing seat 21. A mating ring 311 is fixedly connected to one end of the first arm plate 31 near the pressing seat 21. The mating ring 311 rotates in the mating groove 22. Four mating gaps 3111 are distributed circumferentially along the inner edge of the mating ring 311, corresponding one-to-one with the positions of the four mating blocks 232. The positions of the mating gaps 3111 are such that when the swing arm structure 3 is not swinging, the mating blocks 232 are located inside the mating gaps 3111. When the swing arm structure 3 swings, the mating gaps 3111 and the mating blocks 232 rotate relative to each other, and the mating blocks 232 are squeezed back into the telescopic groove 2311. The second arm plate 32 is disposed on the other side of the crimping seat 21. A rotating ring 321 is fixedly connected to one end of the second arm plate 32 near the crimping seat 21. The rotating ring 321 is rotatably assembled in the annular rotating groove 24. The two ends of the connecting shaft 33 are respectively connected and fixed to the first arm plate 31 and the second arm plate 32. The roller 34 is rotatably assembled between the first arm plate 31 and the second arm plate 32. The upper end of the roller 34 protrudes from the first arm plate 31 and the second arm plate 32. When the swing arm structure 3 swings, the internal mating ring 311 rotates during the swing of the swing arm structure 3, thereby pressing and engaging with the mating block 232 outside the fixed ring 231. This allows the mating ring 311 to use its own rotational movement to drive the mating block 232 to make linear displacement inside the telescopic groove 2311, thereby realizing the crimping of the crimping terminal 8.

[0071] Both the first arm plate 31 and the second arm plate 32 have a circular through hole 320 at one end. The circular through hole 320 is concentric with the crimping ring 23. By setting the circular through hole 320 on the first arm plate 31, the operator can visually determine the positioning member 6 through the circular through hole 320, which makes it convenient for the user to insert the crimping terminal 8 into the positioning member 6 for positioning. At the same time, the circular through hole 320 on the second arm plate 32 makes it convenient for the user to remove the positioning member 6 from the circular through hole 320.

[0072] Please see Figure 5 The cable terminal crimping device also includes a coil spring 312, which is concentrically disposed outside the mating ring 311. One end of the coil spring 312 is connected and fixed to the outer edge of the mating ring 311, and the other end is connected and fixed to the inner wall of the mating groove 22. When the swing arm structure 3 swings, it can drive the coil spring 312 to coil up. When the swing arm structure 3 is no longer pressed down by the driven structure 5, the spring force is released through the coil spring 312, thereby enabling the swing arm structure 3 of the device to quickly rebound.

[0073] Please see Figure 1 The driving structure 5 includes a stand 51, a cylinder 52, and a push rod 53. The stand 51 is fixedly mounted on the fixed plate 11. The cylinder 52 is fixedly mounted on the stand 51 in the vertical direction. One end of the push rod 53 is connected and fixed to the drive shaft of the cylinder 52, and extends and retracts up and down under the drive of the cylinder 52. When the push rod 53 is pressed down, it contacts the roller 34 of the swing arm structure 3, causing the swing arm structure 3 to deflect. Thus, when the cylinder 52 drives the push rod 53 to move downward, it can drive the swing arm structure 3 to swing, thereby using the swing of the swing arm structure 3 to realize the rapid crimping of the crimp terminal 8.

[0074] Please see Figure 8 The straightening structure 4 includes: a first telescopic joint 41, a second telescopic joint 42, and a columnar spring 43. One end of the first telescopic joint 41 is rotatably mounted on the vibrating plate 12 via a rotating shaft. One end of the second telescopic joint 42 is coaxially inserted into the first telescopic joint 41 and slidably connected to it, while the other end is rotatably connected to the connecting shaft 33. The columnar spring 43 is sleeved on the second telescopic joint 42, with one end fixedly connected to the second telescopic joint 42 and the other end fixedly connected to the first telescopic joint 41. While the coil spring 312 causes the swing arm structure 3 to swing, the straightening structure 4, which can extend and deflect, provides a certain elastic force when the swing arm structure 3 returns to center, thereby further improving the return speed of the swing arm structure 3. At the same time, the straightening structure 4 can provide certain support for the swing arm structure 3, reducing the burden on the coil spring 312 and making the swing arm structure 3 more stable when swinging.

[0075] Please see Figure 1 The cable terminal crimping device also includes a limiting post 7, which is fixedly mounted on the crimping seat 21 and located below the swing arm structure 3. By setting the limiting post 7, the maximum downward swing amplitude of the swing arm structure 3 is limited, thereby avoiding the situation where the internal mating ring 311 and the mating block 232 disengage due to excessive downward swing of the swing arm structure 3, thus improving the stability of the device during operation.

[0076] In summary, when using the cable terminal crimping device described in this application to crimp a cable and a cable terminal 8, the cable conductor inside the cable is first stripped out using conventional methods and placed at a designated position on the cable terminal 8. Simultaneously, the positioning member 6 corresponding to the cable terminal 8 is assembled onto the crimping device 2. By inserting the cable terminal 8 into the positioning groove in the positioning hole, the cable terminal 8 is placed stably in the positioning groove. At this time, the cylinder 52 is activated, driving the push rod 53 to press down. The push rod 53 abuts against the roller 34. As the pressing proceeds, the roller 34 rolls on the lower end face of the push rod 53, simultaneously driving the swing arm structure 3 to rotate around the annular groove 24. When the shaft swings, the vibrating plate 12 is also subjected to downward pressure, which drives the elastic element 13 to compress until the vibrating plate 12 is in close contact with the fixed plate 11. At this time, the mating ring 311 inside the swing arm structure 3 rotates in the mating groove 22. The edge of the mating gap 3111 presses the arc surface 2321 of the mating block 232, so that the mating block 232 can retract into the telescopic groove 2311 under the pressing action. During the process of the mating block 232 retracting into the telescopic groove 2311, it drives the moving rod 234 to move towards the center of the crimping ring 23, which in turn drives the pressing block 233 to press the specific position of the crimping terminal 8, causing the crimping terminal 8 to deform and tighten the internal cable conductor.

[0077] After the crimping is completed, the cylinder 52 retracts. At this time, the swing arm structure 3 is no longer pressed down by the push rod 53. The swing arm structure 3 can return to the center under the elastic force of the coil spring 312 and the straightening structure 4. At the same time, the vibrating plate 12 rebounds under the elastic force of the elastic element 13, thereby driving the entire crimping device 2 to rebound and vibrate, which facilitates the internal crimping terminal 8 to disengage from the positioning element 6.

[0078] 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.
