[0034] See also 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 assembled on the upper end of the vibration plate 12, the crimping ring 23 is embedded in one side of the upper end of the crimping seat 21, and an annular matching 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 squeeze the cable terminal 8 so that the cable terminal 8 is crimped on the cable, and the annular rotating groove 24, the rotating groove is arranged on the other side of the upper end of the crimping seat 21, the annular rotating groove 24 is concentric with the matching groove 22, and the crimping ring 23 cooperates with the swing arm structure 3, so that the swinging motion of the swing arm structure 3 is converted into a circumferential squeezing motion of the crimping ring 23 on the cable terminal 8, so that the cable terminal 8 can be crimped quickly and efficiently.

[0035] The crimping ring 23 includes: a fixed ring 231, a matching block 232 and an extrusion block 233. The fixed ring 231 is embedded in one side of the upper end of the crimping seat 21.

[0036] In other embodiments, the number of the expansion slots 2311 can also be set to six or other even numbers. Similarly, the number of the mating blocks 232 and the extrusion blocks 233 are synchronously set to six or other even numbers with the expansion slots 2311. According to the crimping requirements of different cable terminals 8, different numbers of extrusion blocks 233 are selected to extrude the crimping terminals 8 to complete the crimping work between the cables and the cable terminals 8.

[0038] See also 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, wherein the first arm plate 31 is arranged on one side of the upper end of the crimping seat 21, and a matching ring 311 is fixedly connected to one side of the crimping seat 21 at one end of the first arm plate 31, and the matching ring 311 rotates in the matching groove 22, and the inner edge of the matching ring 311 is provided with four matching gaps 3111 corresponding to the positions of the four matching blocks 232 at intervals along the circumference of the matching ring 311, wherein the position of the matching gap 3111 can satisfy that when the swing arm structure 3 does not swing, the matching block 232 is located inside the matching gap 3111, and when the swing arm structure 3 swings, the matching gap 3111 and the matching block 232 rotate relative to each other, and squeeze the matching block 232 to retract into the telescopic groove 2311, and the first The second arm plate 32 is arranged on the other side of the crimping seat 21, and one end of the second arm plate 32 is fixedly connected with a rotating ring 321 close to the side of the crimping seat 21, and the rotating ring 321 is rotatably assembled in the annular rotating groove 24, and 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, and the roller 34 is rotatably assembled between the first arm plate 31 and the second arm plate 32, and 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 matching ring 311 rotates itself when the swing arm structure 3 swings, thereby squeezing and cooperating with the matching block 232 outside the fixed ring 231, so that the matching ring 311 uses its own rotation to drive the matching block 232 to make linear displacement inside the telescopic groove 2311, thereby realizing the crimping of the crimping terminal 8.

[0039] A circular through hole 320 is provided at one end of the first arm plate 31 and the second arm plate 32, and 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 staff can visually measure the positioning member 6 through the circular through hole 320, which is 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 can facilitate the user to remove the positioning member 6 from the circular through hole 320.

[0040] See also Figure 5 The cable terminal crimping device also includes a coil spring 312, which is concentrically arranged on the outside of the matching ring 311. One end of the coil spring 312 is connected and fixed to the outer edge of the matching ring 311, and the other end is connected and fixed to the inner wall of the matching groove 22. When the swing arm structure 3 swings, it can drive the coil spring 312 to reel. When the swing arm structure 3 is no longer pressed down by the driven structure 5, the elastic force is released by the coil spring 312, so that the swing arm structure 3 of the device can rebound quickly.

[0041] See also 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 driving shaft of the cylinder 52, and is extended and retracted 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. When the push rod 53 is driven downward by the cylinder 52, the swing arm structure 3 can be driven to swing, and then the swing of the swing arm structure 3 is used to realize the rapid crimping of the crimping terminal 8.

[0042] See also 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 assembled on the vibration plate 12 through a rotating shaft, a second telescopic joint 42, one end of the second telescopic joint 42 is coaxially inserted into the first telescopic joint 41, and is slidably connected to the first telescopic joint 41, and the other end is rotatably connected to the connecting shaft 33, a columnar spring 43, the columnar spring 43 is sleeved on the second telescopic joint 42, one end of the columnar spring 43 is connected and fixed to the second telescopic joint 42, and the other end is connected and fixed to the first telescopic joint 41. While the coil spring 312 is set to make the swing arm structure 3 swing, a straightening structure 4 that can be telescopically deflected is set to provide a certain elastic force when the swing arm structure 3 is returned, thereby further improving the return speed of the swing arm structure 3. At the same time, the straightening structure 4 can provide a certain support to the swing arm structure 3, reducing the burden of the coil spring 312, so that the swing arm structure 3 is more stable when swinging.

[0043] See also Figure 1 The cable terminal crimping device also includes a limiting column 7, which is fixedly assembled on the crimping seat 21 and is located below the swing arm structure 3. By setting the limiting column 7, the maximum downward swing amplitude of the swing arm structure 3 is limited, thereby avoiding the situation where the internal matching ring 311 and the matching block 232 are out of engagement due to the swing arm structure 3 swinging downward too much, thereby improving the stability of the device during operation.

[0044] In summary, when it is necessary to use a cable terminal crimping device involved in the present application to crimp a cable and a cable terminal 8, firstly, the cable conductor inside the cable is stripped out by conventional means and set at a specified position on the cable terminal 8. At the same time, the positioning piece 6 corresponding to the cable terminal 8 is assembled on the crimping device 2, and the cable terminal 8 is inserted into the positioning groove in the positioning hole, so that the cable terminal 8 can be placed stably in the positioning groove. At this time, the cylinder 52 is turned on, and the cylinder 52 drives the push rod 53 to press down, and the push rod 53 resists the roller 34. As the downward pressure is carried out, the roller 34 rolls on the lower end surface of the push rod 53, while driving the swing arm structure 3 to rotate in the annular groove 24. The shaft swings, and the vibration plate 12 is also subjected to downward pressure, which drives the elastic member 13 to be compressed until the vibration plate 12 is tightly attached to the fixed plate 11. At this time, the matching ring 311 inside the swing arm structure 3 rotates in the matching groove 22, and the edge of the matching gap 3111 squeezes the arc surface 2321 of the matching block 232, so that the matching block 232 can retract into the telescopic groove 2311 under the squeezing action. In the process of retracting into the telescopic groove 2311, the matching block 232 drives the moving rod 234 to move toward the center of the crimping ring 23, thereby driving the squeezing block 233 to squeeze the specific position of the crimping terminal 8, so that the crimping terminal 8 is deformed and the internal cable conductor is tightened; 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 vibration plate 12 rebounds under the elastic action of the elastic member 13, thereby driving the entire crimping device 2 to rebound and vibrate, making it convenient for the internal crimping terminal 8 to disengage from the cooperation with the positioning member 6.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
