[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] The crimping device of the fisheye terminal of the utility model embodiment comprises a support assembly 1, a positioning plate 2 and a crimping assembly 3. The support assembly 1 comprises a first support member 11 and a second support member 12. The first support member 11 and the second support member 12 are arranged in a first direction (such as Figure 1 The first support member 11 is provided with a positioning plate 2, which is suitable for placing a circuit board. The positioning plate 2 is provided with a positioning groove 21 that matches the conductive hole on the circuit board. The positioning groove 21 is suitable for placing the fixed end of the fisheye terminal, and the conductive hole is used to place the connecting end of the fisheye terminal. The crimping assembly 3 is connected to the second support member 12, and one end of the crimping assembly 3 passes through the second support member 12. One end of the crimping assembly 3 can approach and move away from the first support member 11 so that the connecting end of the fisheye terminal is pressed into the conductive hole.

[0024] Specifically, Figure 1 and Figure 2 As shown, the second support member 12 is located above the first support member 11, and the support assembly 1 also includes a fixing plate 13, the lower end of which is connected to the first support member 11, and the upper end of which is connected to the second support member 12. The positioning plate 2 is installed at the upper end of the first support member 11, and a positioning groove 21 is provided on the upper end surface of the positioning plate 2 to match the conductive hole of the circuit board. By placing the fixed end of the fisheye terminal in the positioning groove 21 in advance, it is ensured that the position of the fisheye terminal is kept relatively fixed when the fisheye terminal is pressed in, which is convenient for positioning and crimping the circuit board. The crimping assembly 3 is installed on the second support member 12, and the lower end of the crimping assembly 3 passes through the second support member 12, and the spacing distance between the lower end of the crimping assembly 3 and the first support member 11 is adjustable, so that the crimping assembly 3 moves downward to crimp the circuit board.

[0025] For example, the positioning plate 2 and the first support member 11 are detachably connected, so that different positioning plates 2 can be easily replaced to adapt to different circuit boards.

[0026] The crimping device of the fisheye terminal of the embodiment of the utility model is provided with a first support member 11 and a second support member 12 which are spaced apart from each other, a positioning plate 2 is provided on the first support member 11, and a crimping assembly 3 is provided on the second support member 12. When installing the fisheye terminal, the fixed end of the fisheye terminal is pre-placed in the positioning groove 21 of the positioning plate 2, and then the circuit board is placed on the positioning plate 2, and at the same time, the connecting end of the fisheye terminal is pre-inserted into the conductive hole, and pressure is applied to the circuit board by moving the lower end of the crimping assembly 3 downward, and the connecting end of the fisheye terminal is inserted into the conductive hole under the action of pressure, thereby improving the assembly accuracy.

[0027] Furthermore, there are multiple positioning grooves 21 on the positioning plate 2, which is convenient for connecting multiple fisheye terminals to the circuit board at the same time, thereby improving assembly efficiency. Moreover, under the pressure applied by the crimping assembly 3, the connecting ends of the multiple fisheye terminals are subjected to the same pressure, so that the multiple fisheye terminals are pressed into the circuit board to the same depth, thereby ensuring the consistency and stability of the pressing depth, rather than relying on the operator's experience and proficiency, thereby improving assembly accuracy and assembly efficiency.

[0028] Furthermore, in this embodiment, by adjusting the spacing distance between the crimping assembly 3 and the circuit board, the depth of the connecting end of the fisheye terminal pressed into the circuit board can be adjusted to meet different connection requirements and improve the adaptability of the crimping device.

[0029] In some embodiments, the crimping device of the fisheye terminal also includes a base plate 4, one end of which is connected to the first support member 11, and the other end of the base plate 4 is movably connected to the positioning plate 2 so that the positioning plate 2 can move closer to and away from the supporting assembly 1.

[0030] Specifically, Figure 1 As shown, the lower end of the base plate 4 is connected to the upper end of the first support member 11, and the upper end of the base plate 4 is movably connected to the lower end of the positioning plate 2. The base plate 4 extends in the front-to-back direction. Through the movable connection between the fixed plate and the base plate 4, the positioning plate 2 can be moved in the front-to-back direction relative to the base plate 4. The positioning plate 2 is moved in the direction away from the support assembly 1, that is, the positioning plate 2 is pulled backward to facilitate the placement of the fisheye terminal and the circuit board. The positioning plate 2 is moved in the direction close to the support assembly 1, that is, the positioning plate 2 is pushed forward to facilitate the crimping assembly 3 to crimp the circuit board.

[0031] For example, a slide groove is provided on the bottom plate 4 , and the slide groove extends along the front-rear direction. A sliding block that cooperates with the slide groove is provided on the positioning plate 2 , so as to realize the sliding connection between the positioning plate 2 and the bottom plate 4 .

[0032] For example, the positioning plate 2 and the bottom plate 4 are detachably connected, which is convenient for replacing different positioning plates 2. There are two positioning plates 2, which are arranged in sequence in the front-to-back direction. The arrangement of the two positioning plates 2 is convenient for adapting to two different circuit boards. When the rear positioning plate 2 is needed, the positioning plate 2 is first taken out, and the positions of the front and rear positioning plates 2 are adjusted after flipping, and the positioning plate 2 located at the rear side is adjusted to the front side, thereby improving the adaptability of the crimping device.

[0033] For example, the bottom plate 4 is an aluminum bottom plate, which is beneficial to light weight while ensuring sufficient strength and rigidity to meet the pressing operation of the crimping assembly 3 .

[0034] In some embodiments, the crimping device of the fisheye terminal further includes a limiter 5 , which is connected to the base plate 4 or the support assembly 1 , and extends along a first direction, and is used to limit the positioning plate 2 .

[0035] Specifically, Figure 2 As shown, the limit member 5 extends in the up and down directions, and the lower end of the limit member 5 is connected to the bottom plate 4 or the first support member 11. Through the setting of the limit member 5, it is convenient to limit the moving position of the positioning plate 2 moving forward, ensuring that the positioning plate 2 is located directly below the crimping assembly 3, which is convenient for crimping of the crimping assembly 3.

[0036] In some embodiments, the crimping device of the fisheye terminal also includes a first adsorption member (not shown in the figure), which is installed on the limiting member 5, and a second adsorption member (not shown in the figure) is provided on the positioning plate 2. The first adsorption member and the second adsorption member can be adsorbed and connected to fix the position of the positioning plate 2.

[0037] Specifically, the first adsorption member is installed at the rear end of the limit member 5, and the second adsorption member is installed at the front end of the positioning plate 2. The setting of the first adsorption member and the second adsorption member facilitates fixing the position of the positioning plate 2 when the positioning plate 2 moves forward to directly below the crimping assembly 3, thereby avoiding sliding of the positioning plate 2 during the crimping process and improving the stability of the positioning plate 2.

[0038] For example, the first adsorption member and the second adsorption member are magnets, and the positioning plate 2 is made of anti-static material.

[0039] In some embodiments, the crimping assembly 3 includes a rod body 31, a pressure block 32 and a handle 33. One end of the rod body 31 passes through the second support member 12 and is connected to the pressure block 32. The handle 33 is connected to the other end of the rod body 31 to drive the rod body 31 to move closer to and away from the first support member 11.

[0040] Specifically, Figure 1 and Figure 2As shown, the rod body 31 extends in the up-down direction, the lower end of the rod body 31 passes through the second support member 12 and is connected to the pressing block 32, and the handle 33 is connected to the upper end of the rod body 31. By adjusting the position of the handle 33, the different heights of the lower end of the rod body 31 can be adjusted, so that the lower end of the rod body 31 moves downward, and the pressing block 32 presses the circuit board, or the rod body 31 moves upward and the pressing block 32 moves away from the circuit board, so as to facilitate the removal of the circuit board after crimping.

[0041] For example, there are two crimping assemblies 3, which are spaced apart in the left-right direction, so as to facilitate the crimping of fisheye terminals at different positions of the circuit board at the same time. The structure is simple and easy to operate.

[0042] In some embodiments, the crimping assembly 3 also includes a transmission component 34, the transmission component 34 includes a first rod 341, a second rod 342 and a third rod 343, one end of the first rod 341 is connected to the handle 33, the other end of the first rod 341 is hinged to one end of the second rod 342 and the third rod 343, the other end of the second rod 342 is hinged to the other end of the rod body 31, and the other end of the third rod 343 is hinged to the second support member 12.

[0043] Specifically, Figure 1 and Figure 2 As shown, the number of the first rod 341, the second rod 342 and the third rod 343 are all two, the two first rods 341 are symmetrically arranged in the front-to-back direction, the two second rods 342 and the two third rods 343 are symmetrically arranged in the front-to-back direction, and the two second rods 342 are both located inside the two third rods 343, that is, the second rod 342 is arranged adjacent to the rod body 31 compared with the third rod 343. The transmission component 34 has a first state and a second state. In the first state, the first rod 341 extends in the left-right direction, the second rod 342 and the third rod 343 both extend in the up-down direction, one end of the first rod 341 is hinged to the upper end of the second rod 342 and the third rod 343, that is, the hinge point between the first rod 341 and the second rod 342 and the hinge point between the first rod 341 and the third rod 343 are the same hinge point, the lower end of the second rod 342 is hinged to the upper end of the rod body 31, and the lower end of the third rod 343 is hinged to the second support member 12.

[0044] When the first state moves to the second state, the handle 33 is rotated to the left or right around the front-back direction. Here, the handle 33 is rotated to the left as an example. The upper ends of the third rod 343 and the second rod 342 tilt to the left, and the lower end of the second rod 342 moves upward, thereby driving the rod body 31 to move upward. When the second state moves to the first state, the handle 33 is rotated to the left or right around the front-back direction. Here, the handle 33 is rotated to the right as an example. The third rod 343 moves in the vertical direction, the second rod 342 and the third rod 343 remain parallel, and the second rod 342 drives the rod body 31 to move downward. In this embodiment, through the setting of the transmission component 34, when the first state moves to the second state, the handle 33 is pulled back upward, and when the second state moves to the first state, the handle 33 is pressed downward to the lowest position, so that the handle 33 moves upward to release and moves downward to press, thereby reducing the difficulty of operating the crimping assembly 3.

[0045] In some embodiments, the crimping assembly 3 also includes a fixing member 35, which is sleeved on the rod body 31, and the rod body 31 is movable relative to the fixing member 35. The fixing member 35 is connected to the second support member 12, and the other end of the third rod 343 is hinged to the fixing member 35.

[0046] Specifically, the rod body 31 can move up and down relative to the fixing member 35 . The setting of the fixing member 35 facilitates fixing the crimping assembly 3 on the second supporting member 12 .

[0047] For example, the fixing member 35 is a nut.

[0048] In some embodiments, the rod body 31 includes a sleeve 311 and a threaded rod 312, one end of the threaded rod 312 is connected to the pressing block 32, the other end of the threaded rod 312 is threadedly connected to the sleeve 311, and the distance that the threaded rod 312 extends into the sleeve 311 is adjustable.

[0049] Specifically, the lower end of the threaded rod 312 is connected to the pressing block 32, and the upper end of the threaded rod 312 can be inserted into the sleeve 311 and threadedly connected to the sleeve 311. By adjusting the distance that the threaded rod 312 extends into the sleeve 311, the crimping assembly 3 can be adjusted to different pressing heights.

[0050] For example, the rod body 31 further includes a positioning member 313, and the positioning member 313 is sleeved on the threaded rod 312. By adjusting the height of the positioning member 313 on the threaded rod 312, it is convenient to adjust different crimping heights, thereby improving the convenience of adjustment.

[0051] In some embodiments, the crimping device of the fisheye terminal further includes a guide rod 6 , one end of the guide rod 6 is movably connected to the second support member 12 , and the other end of the guide rod 6 is connected to the pressing block 32 .

[0052] Specifically, the upper end of the guide rod 6 is movably connected to the second support member 12, and the lower end of the guide rod 6 is connected to the pressure block 32. When the pressure block 32 moves upward, the upper end of the guide rod 6 moves upward synchronously, and when the pressure block 32 moves downward, the upper end of the guide rod 6 moves downward synchronously.

[0053] For example, there are two guide rods 6 , which are symmetrically arranged in the front-to-back direction. The arrangement of the guide rods 6 improves the movement stability of the crimping assembly 3 .

[0054] In some embodiments, a avoidance hole 22 is provided on the positioning plate 2 .

[0055] Specifically, Figure 1 As shown, by providing the avoidance hole 22 on the positioning plate 2, it is convenient to avoid the electronic components on the circuit board.
