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

[0002] During cable processing, crimping equipment is used to press the cable and terminals together, a key process that achieves a permanent connection between the conductor and the terminal through physical compression. The ultimate goal is to ensure good electrical conductivity, reliable mechanical strength, and long-term stable use at the connection point.

[0003] In the process of crimping cables and terminals, the cut cables are often manually fed into the designated position of the crimping equipment before being crimped. Although manual feeding can ensure a high quality rate, the processing efficiency is low and there are certain dangers involved.

[0013] As an optional embodiment of the terminal and cable crimping device of the present invention, the limiting groove further includes an opening to prevent the ball head from getting stuck, and the opening is disposed at the joint of the smooth groove and the transverse groove.

[0014] As an optional embodiment of the terminal and cable crimping device of the present invention, a baffle that is rotatably connected to the processing table is installed at the joint between the inclined groove and the reset groove to limit the sliding of the ball head. One end of a torsion spring is fixed to the outer wall of the baffle, and the other end of the torsion spring is fixed to the processing table.

[0015] As an optional embodiment of the terminal and cable crimping device of the present invention, wherein: a sliding rod penetrating the interior of the traction arm and a top support spring fixed to one side of the traction arm are respectively installed on the inner side of the traction seat, the top support spring is sleeved on the outside of the sliding rod, and a crossbar penetrating the interior of the sliding seat is fixed on the outer wall of the traction seat.

[0016] As an optional embodiment of the terminal and cable crimping device of the present invention, wherein: a clamping plate for holding the cable is slidably installed inside the sliding seat, a connecting screw is threaded inside the clamping plate, a motor is fixedly mounted on the outer wall of the sliding seat, and the output end of the motor is fixedly connected to the connecting screw.

[0017] As an optional embodiment of the terminal and cable crimping device of the present invention, wherein: a mounting base fixed to the outer wall of the processing table is installed on the side of the sliding seat away from the pulling seat; a drive screw threadedly connected to the sliding seat is movably installed inside the mounting base; one end of the drive screw is connected to a drive motor fixed to the outer wall of the mounting base; and a guide seat for guiding the cable is installed on the top of the mounting base.

The guide plate guides the cable, and the staggered guide plates move closer to each other to achieve the centering and positioning of the cable. The clamping plates then clamp and feed the cable.

[0022] 2. This terminal and cable crimping equipment straightens the cable by controlling the movement of the limiting mechanism, preventing the bent cable from affecting the subsequent crimping process. It also uses a flexible pulling arm to prevent over-stretching of the cable, thus protecting the cable during the straightening process.

[0023] 3. This terminal and cable crimping equipment uses a limiting groove to adjust the clamping force between the clamping plate and the cable. It achieves a larger initial clamping force to straighten the middle of the cable, and then reduces the clamping force to allow the cable and clamping plate to slide relative to each other, thus straightening the cable end.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figures 1 to 12 It includes a processing table 1 and a pressing device 3 mounted on its top, with a sliding seat 7 slidably mounted on one side of the pressing device 3 on the processing table 1; it also includes:

[0039] The tensioning seat 12 is installed between the pressing device 3 and the sliding seat 7. A first hydraulic rod 11 is fixed on the sliding seat 7, and the driving end of the first hydraulic rod 11 extends out from the inside of the sliding seat 7 and is fixed to the tensioning seat 12. A tensioning arm 16 is installed on the tensioning seat 12 to allow the cable to pass through its interior. A limiting mechanism 17 for limiting the cable is installed inside the tensioning arm 16.

[0040] An air chamber 19 is located inside the traction seat 12. An air pipe 18 is connected between the air chamber 19 and the limiting mechanism 17. A push rod 20 and a docking spring 21 are installed inside the air chamber 19. One end of the push rod 20 is fixed to the docking spring 21, and the other end extends out of the traction seat 12 and is fixed with a ball head 22. The processing table 1 is provided with a connecting groove 23 for the push rod 20 to slide and a limiting groove 24 for guiding the movement of the push rod 20. The limiting mechanism 17 includes a connecting cavity 171 located inside the traction arm 16. A push block 172 is slidably installed inside the connecting cavity 171. A return spring 173 is fixed at one end of the push block 172, and the other end extends out of the traction arm 16 and is fixed with a clamping piece 174.

[0041] The limiting groove 24 includes a smooth groove 241, a horizontal groove 242, an inclined groove 244 and a reset groove 245 connected in sequence. The horizontal height of the smooth groove 241 is higher than that of the horizontal groove 242. The limiting groove 24 also includes an opening 243 to prevent the ball head 22 from getting stuck. The opening 243 is located at the joint of the smooth groove 241 and the horizontal groove 242. The sliding seat 7 is mounted on the side away from the pulling seat 12 and is fixed to the outer wall of the processing table 1. The interior of the mounting seat 4 is movably mounted with a drive screw 6 that is threadedly connected to the sliding seat 7. One end of the drive screw 6 is connected to a drive motor 5 that is fixed to the outer wall of the mounting seat 4. The top of the mounting seat 4 is mounted with a guide seat 31 for guiding cables.

[0042] A cutting table 27 is installed between the mounting base 4 and the sliding base 7. A third hydraulic rod 30 is fixed to the outer side wall of the cutting table 27 and is fixed to the mounting base 4. A second hydraulic rod 28 is fixed to the outer top wall of the cutting table 27. The output end of the second hydraulic rod 28 passes through the cutting table 27 and is fixed with a cutting blade 29. A wire spool 2 that fixes the outer wall of the processing table 1 is installed on one side of the mounting base 4. A clamping plate 8 for holding the cable is slidably installed inside the sliding base 7. A connecting screw 9 is threaded inside the clamping plate 8. A mounting motor 10 is fixed to the outer wall of the sliding base 7. The output end of the mounting motor 10 is fixedly connected to the connecting screw 9.

[0043] First, the cable on the reel 2 is passed through the guide seat 31 fixed on the mounting base 4, and the end of the cable is positioned at the cutting blade 29 inside the cutting table 27. Initially, the cutting table 27 and the cable are not on the same initial plane. This setting ensures that when the sliding seat 7 moves closer to and fits against the mounting base 4, it will not collide with the cutting table 27. When the sliding seat 7 fits against the mounting base 4, one end of the cable is located in the circular hole on the pulling arm 16. At this time, there is a gap between the sliding seat 7 and the pulling seat 12. By controlling the movement of the first hydraulic rod 11 fixed on the sliding seat 7, the pulling seat 12 is driven to fit against the sliding seat 7. During the process of the sliding seat 7 fitting against the pulling seat 12, the push rod 20 and the ball head 22 move synchronously, allowing the push rod 20 to slide inside the connecting groove 23 while the ball head 22 slides inside the smooth groove 241. When the sliding seat 7 and the pulling seat 12 are in contact, the ball head 22 slides to the docking point of the smooth groove 241 and the transverse groove 242. At this time, the docking spring 21, which is in a compressed state, drives the push rod 20 to slide downward along the axis of the push rod 20 inside the air chamber 19. In order to make the ball head 22 slide quickly, an opening 243 is provided at the smooth groove 241 and the transverse groove 242, so that the push rod 20 and the ball head 22 are acted upon by the docking spring 21, allowing the ball head 22 to slide quickly to the bottom of the opening 243. And because the opening 243 has a large space, when the ball head 22 moves closer to the inclined groove 244, it avoids the situation where the ball head 22 gets stuck due to the small connection gap between the smooth groove 241 and the transverse groove 242. It should be noted that when the ball head 22 moves to the bottom of the transverse groove 242, the docking spring 21 is still in a compressed state that is not fully released.

[0044] When the push rod 20 slides inside the air chamber 19, it compresses the gas inside the air chamber 19 and allows the gas to enter the connecting cavity 171 inside the traction arm 16 through the air pipe 18. As the gas inside the connecting cavity 171 increases, it drives the push block 172 to slide inside the connecting cavity 171 and drives the clamping piece 174 to move, so that the clamping pieces 174 on both sides move closer to each other and finally clamp and position the cable.

[0045] The connecting cavity 171 is also equipped with a reset spring 173. When the push block 172 moves, it will stretch the reset spring 173 simultaneously. By using the reset spring 173, the push block 172 can be reset quickly and stably.

[0046] After the clamping plate 174 clamps the cable, the first hydraulic rod 11 is moved again by controlling its movement. This causes the first hydraulic rod 11 to drive the pulling arm 16 on the pulling seat 12 to move away from the sliding seat 7. This setup pulls the cable and uses the through hole on the guide seat 31, which is slightly larger than the cable's passage, to initially flatten the cable coiled on the reel 2. As the pulling arm 16 moves, the cable clamped by the clamping plate 174 moves synchronously. The cable stops when the sliding seat 7 and the pulling seat 12 reach a specific distance, which can be 20 centimeters. Those skilled in the art can select the appropriate distance based on the required cable length. At this point, the mounting motor 10 on the sliding seat 7 is controlled to move, causing the connecting screw 9 to rotate. The connecting screw 9 and the clamping plate 8 are connected by threads, and the threads at both ends of the connecting screw 9 are set in opposite directions. The movement of the connecting screw 9 causes the clamping plates 8 on both sides to move in opposite directions. The cable is brought close and clamped for positioning. Subsequently, the drive motor 5 is controlled to move the drive screw 6, moving the sliding seat 7 away from the mounting seat 4 to reserve space for the cutting table 27 to move. Then, the third hydraulic rod 30 is controlled to move the cutting table 27, positioning the cutting blade 29 above the cable. The second hydraulic rod 28 is controlled to move the cutting blade 29 downward to cut the cable. The drive motor 5 is then controlled to rotate the drive screw 6, driving the sliding seat 7 and the pulling seat 12 to move the cut cable synchronously and transport the cable end to the pressing device 3 to achieve the pressing process of the cable and terminal. It should be noted that the pressing device is an integrated stripping and pressing device, which is existing technology. Those skilled in the art can select it according to actual needs. This application only relates to how to achieve automatic cable feeding and does not involve any improvement to the pressing device.

[0047] Example 2 is an improvement upon Example 1, which solves the problem of stable clamping and positioning of the cable end. For details, please refer to [link / reference]. Figures 1 to 12 The clamping piece 174 has two guide pieces 175 fixed at both ends to guide the sliding of the cable. The guide pieces 175 are arranged in an alternating manner.

[0048] To ensure stable clamping and positioning of the cable by the clamping plate 174, guide plates 175 are provided at both ends of the clamping plate 174. The trajectory of the guide plates 175 is arc-shaped, and there are two of them. With this arrangement, when the return spring 173 moves, it will synchronously drive the guide plates 175 to move. Since the guide plates 175 are staggered, when the guide plates 175 move synchronously and stagger, the deflected cable will be guided by the staggered guide plates 175 and gradually move towards the center position, that is, the clamping plate 174 closes its clamping position. Through this arrangement, the wire is finally guided into the clamping plate 174. The thickness of the clamping plate 174 is greater than the thickness of the guide plates 175, which eventually causes the guide plates 175 to close, thus clamping and positioning the cable.

[0049] Example 3 is an improvement on Example 1, making the cable straighter. For details, please refer to [link / reference]. Figures 1 to 12 The inner side of the traction seat 12 is respectively equipped with a slide rod 14 that penetrates the interior of the traction arm 16 and a top support spring 15 fixed to one side of the traction arm 16. The top support spring 15 is sleeved on the outside of the slide rod 14. The outer wall of the traction seat 12 is fixed with a crossbar 13 that penetrates the interior of the sliding seat 7.

[0050] To ensure the cable enters the pressing device 3 more smoothly, during the synchronous movement of the sliding seat 7 and the pulling seat 12 driven by the drive screw 6, the first hydraulic rod 11 is controlled to move the pulling seat 12 away from the sliding seat 7. This setup straightens the cable between the clamping plate 8 and the clamping piece 174. To prevent excessive force on the cable, a sliding rod 14 and a top support spring 15 are provided. When the cable is subjected to excessive force, the pulling arm 16 slides on the sliding rod 14, compressing the top support spring 15 to prevent excessive force and cable damage. A displacement sensor is installed on the 6. When the pulling arm 16 slides on the top support spring 15 for more than a certain distance, the movement of the first hydraulic rod 11 stops, thereby protecting the cable from over-tension. This setting can effectively ensure that the cable is in a straight state. It should be noted that when this operation is completed, the ball head 22 is still sliding inside the transverse groove 242 and has not moved to the inclined groove 244. The drive screw 6 drives the sliding seat 7 to not slide to the center position of the processing table 1. The displacement sensor is existing technology and is not shown in the figure. It is existing technology and can be selected by those skilled in the art according to actual needs.

[0051] Example 4 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 12 A baffle 25, which is rotatably connected to the processing table 1, is installed at the joint between the inclined groove 244 and the reset groove 245 to restrict the sliding of the ball head 22. One end of the torsion spring 26 is fixed to the outer wall of the baffle 25, and the other end of the torsion spring 26 is fixed to the processing table 1.

[0052] As the drive screw 6 drives the sliding seat 7 to slide on the processing table 1, and the sliding seat 7 slides to the center position of the processing table 1, the ball head 22 moves to the end of the transverse groove 242. As the sliding seat 7 drives the pulling seat 12 to continue moving synchronously, the ball head 22 slides from the transverse groove 242 into the inclined groove 244, and moves upward slightly to reduce the pressure in the connecting cavity 171. Since the pushing block 172 in the connecting cavity 171 is propelled by gas, the slight upward movement of the ball head 22 reduces the pushing force on the pushing block 172. At this time, the clamping plate 174 is still in contact with the cable. However, the clamping pressure is less than the clamping pressure when it is in the push block 172. As the ball head 22 continues to move, the ball head 22 moves to the baffle 25 and supports the baffle 25, causing the baffle 25 to rotate to one side. When the baffle 25 rotates, it will torsion spring 26 to store force. When the ball head 22 passes the baffle 25, the reset force of the torsion spring 26 will reset the baffle 25. By using the baffle 25, when the ball head 22 resets, it will move upward along the baffle 25 into the reset groove 245 and finally enter the smooth groove 241 to complete the reset of the ball head 22.

[0053] When the ball head 22 passes the baffle 25, the first hydraulic rod 11 is controlled to move, causing the pulling seat 12 to move away from the sliding seat 7. As the pulling seat 12 gradually moves away from the sliding seat 7, the clamping force of the clamping plate 174 on the cable is relatively small. As the pulling force on the cable increases, the cable and the clamping plate 174 can slide relative to each other. Using this relative sliding, the end of the cable is straightened, that is, the cable at the clamping point of the clamping plate 174 and the cable passing through the clamping plate 174. This setting keeps the end of the cable straight. When the pulling arm 16 separates from the cable, the pulling arm 16 is divided into two parts, the top and the bottom. The first hydraulic rod is fixedly installed at the bottom of the pulling arm 16, and the output end is connected to the pulling arm 16. With the top fixed, the fourth hydraulic rod 32 is controlled to move, causing the bottom of the pulling arm 16 to move downwards, and the cable to be positioned above the pulling arm 16. When the sliding seat 7 passes the junction of the inclined groove 244 and the reset groove 245, the first hydraulic rod 11 drives the pulling seat 12 to move towards the sliding seat 7 to the initial position, so as to avoid the pulling seat 12 affecting the subsequent insertion of the cable into the pressing device 3. It should be noted that the cable is a wire with a certain degree of rigidity, not a soft wire formed by multiple strands of guide wires. Those skilled in the art can set up a conveying mechanism on the processing table 1 to convey the processed cable. When the clamping plate 8 moves to the conveying mechanism, it releases the clamp on the cable, thereby realizing the automatic conveying of the processed workpiece.

[0054] As another alternative to the limiting groove 24, an electric telescopic rod is fixed at the bottom of the traction seat 12. The output end of the electric telescopic rod is fixed to the ball head 22. The output stroke of the electric telescopic rod is divided into three segments: a, b, and c. Segment a is when the ball head 22 enters the horizontal groove 242 from the smooth groove 241; segment b is when the ball head 22 enters the inclined groove 244 from the horizontal groove 242; and segment c is when the ball head 22 returns to the smooth groove 241 from the inclined groove 244. This sequence controls the sliding of the push rod 20 in the air chamber 19.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
