[0002] In many fields such as electric power, communication and electronics, cable connection is a key link in system construction. As a common connection method, cable crimping directly affects the electrical performance, mechanical strength and reliability of the system. Good cable crimping can ensure low resistance and high mechanical strength connection between the cable and the terminal, thereby ensuring the stability of signal transmission and the efficiency of power transmission.
[0003] The existing cable crimping device is bulky and heavy, and needs auxiliary equipment such as external power supply or hydraulic source to crimp the cable. It can only crimp the cable in a specific environment. However, due to the volume and weight of such devices, it is inconvenient to carry and use in special environments such as wild, high altitude and narrow space. When crimping is needed outdoors, special transportation tools are needed to transport such devices for on-site crimping, affecting work efficiency and progress.

DETAILED DESCRIPTION
[0028] The advantages and features of the present application will be more apparent from the following detailed description of preferred embodiments of the present application, taken in conjunction with the accompanying drawings, in which:
[0029] Please refer to Figure 1 - Figure 3 A portable high-precision cable crimping device, comprising a crimping box 1, a crimping jaw 2 and a display screen 3 are slidably connected to the front end of the crimping box 1, and a cable 4 is installed at the rear end of the crimping box 1, one end of the crimping jaw 2 is sleeved with the outer wall of one end of the cable 4, and the crimping jaw 2 and the cable 4 are tightly attached through the sleeving mode, which can better transmit pressure during the crimping process, and form a reliable mechanical connection between the cable 4 and the crimping jaw 2 and other components, and a pressing block 5 is slidably connected to the top of the crimping box 1.
[0030] As Figure 4As shown, the bottom of the pressing block 5 is provided with a pressing mechanism 6, the pressing mechanism 6 includes two connecting strips 601 fixedly connected to the bottom of the pressing block 5, the outer walls of the two connecting strips 601 are fixedly connected with fixing plates 602, the inside of the crimping box 1 is fixedly connected with two limiting plates 603, the inside of the limiting plate 603 is provided with a through hole corresponding to the connecting strip 601, the connecting strip 601 can move up and down in the through hole, the through hole provides a clear path and direction for the movement of the connecting strip 601, ensures that the connecting strip 601 will not deviate or shake during movement, makes the movement of the pressing mechanism 6 more stable and accurate, the first spring 604 is installed between the two limiting plates 603 and the fixing plate 602, the other end of one of the connecting strips 601 is fixedly connected with a connecting ring 605, when a downward pressure is applied to the pressing block 5, the pressing block 5 will drive the two connecting strips 601 at the bottom to move downward together, the fixing plate 602 fixedly connected to the outer wall of the connecting strip 601 will also move downward, because the first spring 604 is installed between the fixing plate 602 and the limiting plate 603, during the downward movement of the fixing plate 602, the first spring 604 will be compressed, thereby generating elastic potential energy, when the external force applied to the pressing block 5 disappears, the first spring 604 will try to restore to the original length, that is, release the elastic potential energy, push the fixing plate 602 and the connecting strip 601 to move upward, so that the pressing block 5 returns to the initial position.
[0031] As shown in the figure, Figure 5 The inside of the crimping box 1 is provided with a crimping mechanism 7, the crimping mechanism 7 includes a fixed circular block 701 installed in the inside of the crimping box 1, a plurality of sliding grooves 702 are formed in the front end of the fixed circular block 701, a plurality of sliding strips 703 are slidingly connected in the inside of the plurality of sliding grooves 702, one end of the plurality of sliding strips 703 is fixedly connected with an arc-shaped crimping block 704, the outer wall of the plurality of arc-shaped crimping blocks 704 is attached to the outer wall of the crimping jaw 2, the outer wall of the plurality of arc-shaped crimping blocks 704 attached to the outer wall of the crimping jaw 2 can apply pressure to the crimping jaw 2 from multiple directions, so that the crimping jaw 2 is more evenly stressed during crimping, which can ensure that the connection between the cable 4 and the connecting terminal and other components is more tightly and stably, improve the crimping quality, reduce the problem of poor connection caused by uneven pressure, the front end of the plurality of sliding strips 703 is fixedly connected with a fixed block 705, the bottom of the plurality of fixed blocks 705 is fixedly connected with a second spring 706, the outer wall of the fixed circular block 701 is rotatably connected with a rotating ring 707, a plurality of slide grooves 708 corresponding to the sliding strip 703 are formed in the front end of the rotating ring 707.
[0032] As shown in the figure, Figure 5As shown, when the connecting bar 601 with the connecting ring 605 pushes the rotating ring 707 to rotate, the sliding groove 708 at the front end of the rotating ring 707 will rotate accordingly. Since the sliding groove 708 corresponds to the sliding bar 703, the rotation of the sliding groove 708 will cause the sliding bar 703 to slide radially within the sliding groove 702. The arc-shaped crimping block 704, which is fixedly connected to one end of the sliding bar 703, will move closer to the cable 4 and the crimping jaws 2 as the sliding bar 703 moves. After the arc-shaped crimping block 704 contacts the cable 4 and the crimping jaws 2, pressure will continue to be applied to rotate the rotating ring 707, which will cause the arc-shaped crimping block 704 to apply pressure to the object to be crimped, thereby realizing the crimping operation. When the pressure disappears, the second spring 706 will push the fixed block 705 to move upward, and the fixed block 705 will then cause the sliding bar 703 to slide in the opposite direction within the sliding groove 702, thereby causing the arc-shaped crimping block 704 to move away from the object to be crimped and return to its initial position.
[0033] like Figure 2 As shown, a contact pressure sensor 8 and a power supply 9 are installed inside the crimp box 1, and an interface 10 corresponding to the power supply 9 is provided on one side of the crimp box 1.
[0034] In use, the stripped cable 4 and crimping jaws 2 are inserted into the designated position on the crimping box 1, ensuring that the cable portion of the cable 4 is inside the crimping jaws 2. Then, pressure is applied to the pressing block 5. This pressure causes the two connecting strips 601 at the bottom to move downwards. When the connecting strip 601 with the connecting ring 605 pushes the rotating ring 707 to rotate, the groove 708 at the front end of the rotating ring 707 rotates accordingly. Since the groove 708 corresponds to the sliding strip 703, the rotation of the groove 708 causes the sliding strip 703 to slide radially within the groove 702. The arc-shaped crimping block 704, fixedly connected to one end of the sliding strip 703, moves closer to the cable 4 and crimping jaws 2 as the sliding strip 703 moves. When the arc-shaped crimping block 704 and the cable... After line 4 contacts the crimping jaws 2, continued pressure is applied to rotate the rotating ring 707, which causes the arc-shaped crimping block 704 to apply pressure to the object to be crimped, thereby realizing the crimping operation. At the same time, the connecting strip 601 begins to contact the contact pressure sensor 8, which transmits the pressure value to the display screen 3 so that the operator can easily check the pressure level. When the pressure disappears, the second spring 706 pushes the fixed block 705 to move upward. The fixed block 705 then drives the sliding strip 703 to slide in the opposite direction in the sliding groove 702, thereby causing the arc-shaped crimping block 704 to move away from the object to be crimped and return to its initial position. The first spring 604 attempts to return to its original length, that is, to release elastic potential energy, pushing the fixed plate 602 and the connecting strip 601 to move upward, so that the pressing block 5 returns to its initial position, waiting for the next crimping operation.
[0035] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made according to the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
