Description

Technical Field

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

[0002] Cable crimping is a process that uses mechanical pressure to plastically deform metal terminals, tightly wrapping them around the cable conductor to form a reliable electrical connection and mechanical fixation. Cable crimping is a crucial step in power transmission and communication connections to achieve a fixed connection between conductors and terminals; it is simple to operate and highly efficient. Manual crimping devices are often used in cable crimping because they require no external power or hydraulic source and offer advantages such as low operational barriers and adaptability to mobile field operations, making them the preferred tool for small-batch wiring and emergency repairs.

[0003] In existing technologies, most manual crimping devices use rigid, fixed handles that cannot be folded for storage. This results in a large space occupation when not in use, affecting the device's portability and storage convenience. Furthermore, the lack of a dedicated storage locking mechanism means that the handle is prone to accidental rotation when touched by external force while idle, potentially causing the crimping block to move and posing a risk of hand injury if the block accidentally closes, thus reducing the device's effectiveness. Therefore, we propose a manual crimping device for cables. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a manual crimping device for cables. It solves the problems that most manual crimping devices use a rigid, fixed connection method for the handle, which cannot be folded and stored. When not in use, they occupy a large space, affecting the convenience of carrying and storing the device. Furthermore, they lack a dedicated storage and locking mechanism. When not in use, the handle is prone to accidental rotation when touched by external force, which in turn drives the crimping block to move. This can easily lead to the risk of the operator's hand being squeezed due to the unexpected closure of the crimping block.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A manual crimping device for cables includes a housing, a fixed seat fixedly connected to the inner wall of the housing, a sliding seat slidably connected to the inner cavity of the housing, crimping blocks installed on the sides of the sliding seat and the fixed seat that are close to each other, a sliding rod symmetrically fixedly connected to the side of the sliding seat away from the crimping block, the sliding rod being slidably connected to the housing, one end of the sliding rod passing through the housing and fixedly connected to an adjusting seat, and a connecting rod symmetrically rotatably connected to the side of the adjusting seat away from the sliding rod. The outer side of the housing is symmetrically connected to a rotating frame. The end of the connecting rod away from the adjusting seat is rotatably connected to the rotating frame. The inner cavity of the rotating frame is rotatably connected to a rotating shaft through a bearing. The outside of the rotating frame is provided with a locking mechanism for locking the position of the rotating shaft. A handle is fixedly sleeved on the outside of the rotating shaft. The inside of the housing is provided with a limiting mechanism for fixing the position of the sliding seat.

[0006] In a preferred embodiment, a fixing rod is fixedly connected to the outer side of the housing, the adjusting seat is slidably sleeved on the fixing rod, and a first spring is sleeved on the outer side of the fixing rod and on the side of the adjusting seat near the slide rod.

[0007] The technical effect of adopting the above-mentioned further solution is that the movement of the adjusting seat can be limited by the setting of the fixing rod, so that the adjusting seat slides along the fixing rod to prevent deviation, and the adjusting seat can be moved and reset by the setting of the first spring.

[0008] In a preferred embodiment, the locking mechanism includes an annular cover fixedly connected to the outer side of the rotating frame. A limiting rod is symmetrically slidably connected inside the annular cover. A second limiting plate is fixedly connected to one end of the limiting rod. The end of the limiting rod away from the second limiting plate extends to the outside of the annular cover. One end of the rotating shaft passes through the rotating frame and extends into the annular cover. A first limiting plate that cooperates with the second limiting plate is fixedly connected to the end of the rotating shaft that enters the annular cover. Multiple teeth are fixedly connected to the opposite side of the first and second limiting plates in an annular array.

[0009] The technical effect of adopting the above-mentioned further solution is that the movement of the second limiting plate can be limited by setting two sets of limiting rods. The movement of the second limiting plate can make its outer teeth close to or separate from the outer teeth of the first limiting plate. When the outer teeth of the second limiting plate are close to the outer teeth of the first limiting plate, the position of the rotating shaft can be locked. When they are separated, the position of the rotating shaft is no longer locked, and it can be rotated.

[0010] In a preferred embodiment, the annular cover is internally threaded with a threaded rod, one end of which is rotatably connected to the second limiting disc via a round shaft, and the end of the threaded rod away from the second limiting disc passes through the annular cover and is fixedly connected to a knob.

[0011] The technical effect of adopting the above-mentioned further solution is that the screw rod is rotated by the knob at one end of the screw rod, and the rotation of the screw rod causes the second limit plate to slide.

[0012] In a preferred embodiment, the limiting mechanism includes a lifting rod slidably connected inside the housing. One end of the lifting rod extends outside the housing and is fixedly connected to a lifting ring. The sliding seat has an insertion hole for use with the lifting rod, and the lifting rod is movably inserted into the insertion hole.

[0013] The technical effect of adopting the above-mentioned further solution is that when the handle is rotated to bring it close to the shell, the handle will contact the lifting ring and squeeze it to move the lifting ring. The lifting ring will drive the lifting rod to move into the insertion hole, thereby locking the position of the sliding seat and preventing accidental operation and shaking of the rotating frame during storage.

[0014] In a preferred embodiment, the housing has an internal receiving groove, and a limiting ring is slidably connected inside the receiving groove. The limiting ring is fixedly sleeved on the lifting rod, and a second spring is sleeved on the outer side of the lifting rod, on the side of the limiting ring away from the lifting ring.

[0015] The technical effect of adopting the above-mentioned further solution is that the movement of the lifting rod can be limited by the setting of the limiting ring, and the movement of the limiting ring can be driven by the setting of the second spring to move and reset. The limiting ring drives the lifting rod to move away from the insertion hole, thereby releasing the locking state of the sliding seat. At this time, the device can be used normally.

[0016] In a preferred embodiment, positioning blocks are symmetrically fixedly connected to the outer surface of the pressing block, and positioning grooves that cooperate with the positioning blocks are symmetrically opened inside the fixed seat and the sliding seat, and the positioning blocks are movably inserted into the positioning grooves.

[0017] The technical advantage of adopting the above-mentioned further solution is that the positioning block and positioning groove can be used to position the pressing block during installation, which facilitates its subsequent installation and fixation.

[0018] In a preferred embodiment, both the interior of the fixed base and the interior of the sliding base are provided with rectangular grooves. A mounting block is symmetrically slidably connected inside the rectangular groove. One end of the mounting block passes through the rectangular groove and extends into the positioning groove. The interior of the positioning block is provided with a mounting groove that cooperates with the mounting block. The mounting block and the mounting groove are movably inserted into each other.

[0019] The technical effect of adopting the above-mentioned further solution is that the position of the positioning block can be locked or unlocked by moving the mounting block into or out of the mounting slot, which facilitates quick assembly and disassembly of the crimping block.

[0020] In a preferred embodiment, a sliding block is slidably connected to the inner wall of the rectangular groove, and a rotating rod is symmetrically rotatably connected to the outer side of the sliding block. The end of the rotating rod away from the sliding block is rotatably connected to the mounting block. A lead screw is rotatably connected to the inside of the rectangular groove through a bearing. The sliding block is threadedly connected to the lead screw. One end of the lead screw passes through the sliding seat and is fixedly connected to a knob. A protrusion is fixedly connected to the inside of the rectangular groove, and one end of the lead screw is rotatably connected to the protrusion through a bearing.

[0021] The technical effect of adopting the above-mentioned further solution is that the rotation of the lead screw drives the sliding block to slide, and the movement of the sliding block drives the two sets of rotating rods to rotate, thereby driving the mounting block to slide.

[0022] This invention provides a manual crimping device for cables. Compared with the prior art, it has the following advantages: 1. This manual cable crimping device features a rotating shaft, a handle, and a locking mechanism, enabling both foldable storage and rigid locking of the handle. This effectively secures the handle in its unfolded or folded state. When folded, the handle rests close to the housing, significantly reducing the overall size of the device and minimizing the space it occupies, making it convenient for storage and carrying. Furthermore, when the handle rotates close to the housing, it engages with a limiting mechanism to fix the position of the sliding seat, preventing the risk of the crimping block being squeezed due to accidental rotation of the handle when idle, thus improving safety during use.

[0023] 2. This manual crimping device for cables enables quick disassembly and replacement of the crimping blocks by incorporating a sliding block, rotating rod, mounting block, positioning block, and mounting groove. The precise fit between the positioning block and the positioning groove facilitates quick positioning, making subsequent installation and fixing of the crimping blocks convenient. Furthermore, no auxiliary tools are required during disassembly and assembly, making the operation easy. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1 to 10 The present invention provides a technical solution: A manual crimping device for cables includes a housing 1. A fixed seat 11 is fixedly connected to the inner wall of the housing 1. A sliding seat 4 is slidably connected to the inner cavity of the housing 1. Crimping blocks 12 are installed on the sides of the sliding seat 4 and the fixed seat 11 that are close to each other. A sliding rod 42 is symmetrically fixedly connected to the side of the sliding seat 4 away from the crimping block 12. The sliding rod 42 is slidably connected to the housing 1. One end of the sliding rod 42 passes through the housing 1 and is fixedly connected to an adjusting seat 41. A connecting rod 21 is symmetrically rotatably connected to the side of the adjusting seat 41 away from the sliding rod 42. When crimping the cable, the insulation layer of the cable is first stripped to expose the conductor. Then, the wire is completely inserted into the special terminal. The terminal is placed between the corresponding die holes of the two sets of crimping blocks 12. The adjusting seat 41 drives the sliding seat 4 to move through the sliding rod 42. The sliding seat 4 drives the crimping block 12 on its side to move closer to the other crimping block 12. Thus, pressure is applied through the two sets of crimping blocks 12, causing the terminal to undergo plastic deformation and tightly wrap the wire, completing the cable crimping operation. A rotating frame 2 is symmetrically rotatably connected to the outer side of the housing 1. The end of the connecting rod 21 away from the adjusting seat 41 is rotatably connected to the rotating frame 2. The inner cavity of the rotating frame 2 is rotatably connected to the rotating shaft 23 through the bearing. The outside of the rotating frame 2 is provided with a locking mechanism for locking the position of the rotating shaft 23. A handle 22 is fixedly sleeved on the outside of the rotating shaft 23. The inside of the housing 1 is provided with a limiting mechanism for fixing the position of the sliding seat 4. A flip groove is opened on the side of the rotating frame 2 that is far away from each other. The side of the flip groove that is far away from the housing 1 is open. The rotating shaft 23 passes through the flip groove. An ear block is fixedly connected to the end of the handle 22 near the rotating frame 2. The ear block is fixedly sleeved on the outside of the rotating shaft 23 by welding. The ear block is in rotatable contact with the flip groove through the rotating shaft 23. When the rotating frame 2 and the handle 22 are in the same straight line, that is, when the handle 22 is opened, the ear block abuts against the bottom of the flip groove. When the two handles 22 are pressed close to each other, the two handles 22 push the two rotating frames 2 close to each other and rotate through the two ear blocks respectively.

[0028] In this design, the handle 22 drives the rotating frame 2 to rotate towards the adjusting seat 41. The rotation of the rotating frame 2 drives the connecting rod 21 to rotate, thereby squeezing and driving the adjusting seat 41 to slide towards the housing 1. The locking mechanism can lock and fix the position of the rotating shaft 23. When not in use, the handle 22 can be rotated and stored close to the housing 1 with the rotating shaft 23 as the center. When normal use is required, the handle 22 can be rotated out for use. The limiting mechanism can cooperate with the limiting mechanism when the handle 22 rotates and presses against the housing 1, thereby fixing the position of the sliding seat 4 and preventing accidental operation and shaking of the rotating frame 2 during storage.

[0029] like Figures 1 to 4As shown: In this scheme, a fixing rod 14 is fixedly connected to the outer side of the housing 1. The adjusting seat 41 is slidably sleeved on the fixing rod 14. A first spring 13 is sleeved on the outer side of the fixing rod 14 and on the side of the adjusting seat 41 near the sliding rod 42. The first spring 13 applies a spring force to the adjusting seat 41, and the adjusting seat 41 is moved and reset by the spring force of the first spring 13. The locking mechanism includes an annular cover 3 fixedly connected to the outer side of the rotating frame 2. A limit rod 32 is symmetrically slidably connected inside the annular cover 3. A second limit plate 33 is fixedly connected to one end of the limit rod 32. The end of the limit rod 32 away from the second limit plate 33 extends to the outside of the annular cover 3. One end of the rotating shaft 23 passes through the rotating frame 2 and extends into the annular cover 3. The end of the rotating shaft 23 that enters the annular cover 3 is fixedly connected to... A first limiting plate 24 is used in conjunction with the second limiting plate 33. The first limiting plate 24 and the second limiting plate 33 are both fixedly connected in a ring array on opposite sides. The teeth on the side of the first limiting plate 24 and the teeth on the side of the second limiting plate 33 engage to lock the position of the rotating shaft 23. A threaded rod 31 is threadedly connected inside the annular cover 3. One end of the threaded rod 31 is rotatably connected to the second limiting plate 33 through a round shaft. The diameter of the round shaft is larger at the end closer to the second limiting plate 33 to limit the rotation of the threaded rod 31, so that the threaded rod 31 can only rotate along the inner wall of the second limiting plate 33 and will not disengage from the inside of the second limiting plate 33. The end of the threaded rod 31 away from the second limiting plate 33 passes through the annular cover 3 and is fixedly connected to a knob.

[0030] In this design, when the device needs to be stored after use, the threaded rod 31 is rotated. The rotation of the threaded rod 31 causes the second limiting plate 33 to slide, so that the teeth on the outer side of the second limiting plate 33 are separated from the teeth on the outer side of the first limiting plate 24, and the position of the rotating shaft 23 is no longer locked. The handle 22 is rotated to bring it close to the housing 1. After it is close, the threaded rod 31 is rotated in the opposite direction. The reverse rotation of the threaded rod 31 causes the second limiting plate 33 to move and reset, so that the teeth on the outer side of the second limiting plate 33 are tightly engaged with the teeth on the outer side of the first limiting plate 24, preventing the rotating shaft 23 from rotating.

[0031] like Figures 5 to 7As shown: In this scheme, the limiting mechanism includes a lifting rod 53 slidably connected inside the housing 1. One end of the lifting rod 53 extends outside the housing 1 and is fixedly connected to a lifting ring 54. The sliding seat 4 has an insertion hole 43 inside that cooperates with the lifting rod 53. The lifting rod 53 is movably inserted into the insertion hole 43. The housing 1 has a receiving groove 5 inside. A limiting ring 52 is slidably connected inside the receiving groove 5. The lifting rod 53 passes through the inner cavity of the receiving groove 5. The limiting ring 52 is fixedly sleeved on the lifting rod 53. A second spring 51 is sleeved on the outer side of the lifting rod 53 and on the side of the limiting ring 52 away from the lifting ring 54. The second spring 51 applies a spring force to the limiting ring 52. The spring force of the second spring 51 drives the limiting ring 52 to move and reset. The limiting ring 52 drives the lifting rod 53 to disengage from the insertion hole 43.

[0032] In this solution, as the handle 22 is rotated to bring it close to the housing 1, the handle 22 will contact the lifting ring 54 and squeeze it to move the lifting ring 54. The lifting ring 54 drives the limiting ring 52 to move through the lifting rod 53, the second spring 51 is compressed, and at the same time, the lifting rod 53 will move into the insertion hole 43, thereby locking the position of the sliding seat 4 to prevent accidental operation and shaking of the rotating frame 2 during storage. When the handle 22 is rotated away from the housing 1, the second spring 51 will move and reset the limiting ring 52 due to the elastic force. The limiting ring 52 will move the lifting rod 53 away from the insertion hole 43, thereby releasing the locking state of the sliding seat 4. At this time, the device can be used normally.

[0033] like Figure 8 and Figure 9As shown: In this scheme, convex positioning blocks 16 are symmetrically fixedly connected to the outer surface of the crimping block 12. Positioning grooves 45, which cooperate with the positioning blocks 16, are symmetrically opened inside the fixed seat 11 and the sliding seat 4 for positioning during crimping block 12 installation. The positioning blocks 16 are movably inserted into the positioning grooves 45. Rectangular grooves 49 are opened inside the fixed seat 11 and the sliding seat 4. Mounting blocks 44 are symmetrically slidably connected inside the rectangular grooves 49, and the mounting blocks 44 are in contact with the inner wall of the rectangular grooves 49, so that the mounting blocks 44 can only slide along the inner wall of the rectangular grooves 49. One end of the mounting block 44 passes through the rectangular groove 49 and extends into the positioning groove 45. The positioning block 16 has an mounting groove 15 that cooperates with the mounting block 44. The rectangular groove 49 is movably connected to the mounting slot 15; a sliding block 47 is slidably connected to the inner wall of the rectangular groove 49, and a rotating rod 46 is symmetrically rotatably connected to the outer side of the sliding block 47. The end of the rotating rod 46 away from the sliding block 47 is rotatably connected to the mounting block 44. A lead screw 48 is rotatably connected to the inside of the rectangular groove 49 through a bearing. The sliding block 47 is threadedly connected to the lead screw 48. One end of the lead screw 48 passes through the sliding seat 4 and is fixedly connected to a knob. A protrusion 410 is fixedly connected to the inside of the rectangular groove 49. One end of the lead screw 48 is rotatably connected to the protrusion 410 through a bearing. The end of the lead screw 48 away from the protrusion 410 is rotatably connected to the sliding seat 4 or the fixed seat 11 through a bearing. An adjustment groove is opened on the side of the sliding seat 4 and the fixed seat 11 that is away from each other. The knob is rotatably installed in the adjustment groove.

[0034] In this solution, when it is necessary to replace the crimping block 12 for use, turn the knob at one end of the lead screw 48 to drive the lead screw 48 to rotate, which in turn drives the sliding block 47 to slide along the inner wall of the rectangular groove 49. The movement of the sliding block 47 drives the rotating rod 46 to rotate, thereby driving the two sets of mounting blocks 44 to move away from the mounting groove 15, releasing the locking state of the positioning block 16, and the crimping block 12 can be removed for replacement. When installing the crimping block 12, push the positioning block 16 into the positioning groove 45, rotate the screw 48 in the opposite direction, and drive the sliding block 47 to move and reset through the reverse rotation of the screw 48. The movement of the sliding block 47 drives the rotating rod 46 to rotate, thereby moving the mounting block 44 into the mounting groove 15, which can lock the position of the positioning block 16 and complete the replacement operation of the crimping block 12.

[0035] Working principle: When using this device, first strip the cable insulation to expose the conductor. Then, fully insert the wire into the dedicated terminal and place the terminal between the corresponding die holes of the two sets of crimping blocks 12. During normal use, the second limiting disc 33 will lock the position of the first limiting disc 24 through its teeth, thereby preventing the rotating shaft 23 from rotating. At this time, rotating the handle 22 can drive the rotating frame 2 to rotate. Rotating both sets of handles 22 will cause the two sets of rotating frames 2 to rotate in opposite directions. The rotation of the rotating frame 2 will drive the connecting rod 21 to rotate. The rotation causes the adjusting seat 41 to slide along the fixed rod 14, compressing the first spring 13. The adjusting seat 41 moves the sliding seat 4 via the slide rod 42, and the sliding seat 4 moves the crimping block 12 on its side closer to another crimping block 12. Pressure is applied through the two sets of crimping blocks 12, causing the terminal to undergo plastic deformation and tightly wrap the wire, thus completing the cable crimping operation. When the handle 22 is released, the first spring 13 will move and reset the adjusting seat 41 due to its elasticity, thereby driving the rotating frame 2 to rotate and reset. When storing the device after use, hold the adjusting seat 41 and the fixing rod 14 with one hand to prevent the adjusting seat 41 from moving, thus aligning the lifting rod 53 with the insertion hole 43. Rotate the threaded rod 31, which causes the second limiting plate 33 to slide outward, disengaging the teeth of the second limiting plate 33 from the teeth of the first limiting plate 24, thus removing the locking of the rotating shaft 23. Flip the handle 22 outward to bring it close to the housing 1. During this process, the handle 22 will contact the lifting ring 54 and squeeze the belt. The moving lifting ring 54 moves, and the lifting ring 54 drives the limiting ring 52 to move through the lifting rod 53. The second spring 51 is compressed. At the same time, the lifting rod 53 moves into the insertion hole 43, thereby locking the position of the sliding seat 4 to prevent accidental operation and shaking of the rotating frame 2 during storage. The threaded rod 31 is rotated in the opposite direction, and the reverse rotation of the threaded rod 31 drives the second limiting plate 33 to move and reset, so that the teeth on the outside of the second limiting plate 33 are tightly attached to the teeth on the outside of the first limiting plate 24, preventing the rotating shaft 23 from rotating. When the device needs to be unfolded for use, rotate the threaded rod 31. The rotation of the threaded rod 31 causes the second limiting plate 33 to slide, so that the teeth on the outer side of the second limiting plate 33 are separated from the teeth on the outer side of the first limiting plate 24, and the position of the rotating shaft 23 is no longer locked. Rotate the handle 22 away from the housing 1, and rotate the threaded rod 31 in the opposite direction. The reverse rotation of the threaded rod 31 causes the second limiting plate 33 to move and reset, so that the teeth on the outer side of the second limiting plate 33 are pressed against the teeth on the outer side of the first limiting plate 24, preventing the rotating shaft 23 from rotating. At the same time, when the handle 22 is away from the housing 1, the second spring 51 will drive the limiting ring 52 to move and reset due to the elastic force. The limiting ring 52 drives the lifting rod 53 to move away from the insertion hole 43, thereby releasing the locking state of the sliding seat 4. At this time, the device can be used normally. When it is necessary to replace the crimping block 12, turn the knob at one end of the screw 48 to rotate the screw 48, which in turn causes the sliding block 47 to slide along the inner wall of the rectangular groove 49. The movement of the sliding block 47 causes the rotating rod 46 to rotate, which in turn causes the two sets of mounting blocks 44 to move away from the mounting groove 15, releasing the locking state of the positioning block 16. The crimping block 12 can then be removed for replacement. When installing the crimping block 12, push the positioning block 16 into the positioning groove 45, and rotate the screw 48 in the opposite direction. The reverse rotation of the screw 48 causes the sliding block 47 to move and reset. The movement of the sliding block 47 causes the rotating rod 46 to rotate, which in turn causes the mounting block 44 to move into the mounting groove 15. The position of the positioning block 16 can then be locked, completing the replacement operation of the crimping block 12.
