[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-2 As shown, a smart switch live and neutral wire terminal crimping structure includes a base 1, a crimping upper mold assembly 6, and a positioning connection assembly 11. A side frame 3 is fixed to the rear side of the base 1, and a cylinder 4 is installed in the middle of the side frame 3. A piston rod 5 is provided on the lower side of the cylinder 4. The crimping upper mold assembly 6 is installed at the bottom of the piston rod 5. The crimping upper mold assembly 6 includes a lifting plate 601, an upper mounting plate 602, an upper mold body 603, and a pressing block 604. The lifting plate 601 is fixedly connected to the piston rod 5, and the upper mounting plate 602 is fixed to both sides of the lower side of the lifting plate 601. The middle of the lifting plate 601... The upper mold body 603 is installed on the lower side, and the lower middle part of the upper mold body 603 is integrally fixed with a pressure block 604. The upper mold assembly 6 also includes a mating plate 605. The upper sides of the upper mold body 603 are fixed with mating plates 605, and the middle part of the mating plate 605 is provided with a positioning hole 12. The pressure block 604 of the upper mold body 603 is used to perform crimping operations on the live and neutral terminals of the smart switch. The two mating plates 605 on both sides of the upper mold body 603 can be slidably installed into the interior of the upper mounting plate 602 to facilitate the disassembly and replacement of the upper mold body 603 with pressure blocks 604 of different sizes.

[0022] like Figure 1 and Figure 3As shown, a movable mounting seat 7 is slidably installed on the upper side of the base 1, and a pressing lower mold assembly 9 is installed on the upper side of the middle part of the movable mounting seat 7. Two limiting protrusions 2 are fixed on the upper surface of the base 1, and a sliding groove 8 corresponding to the limiting protrusions 2 is opened at the bottom of the movable mounting seat 7. The pressing lower mold assembly 9 includes a lower mold body 901, a pressing groove 902 and an ear plate 903. A pressing groove 902 is opened on the inner side of the middle part of the lower mold body 901, and ear plates 903 are fixed on both the left and right sides of the lower mold body 901. A positioning hole 12 is opened in the middle of the ear plate 903. The lower mold body 901 and the pressing groove 902 are used to cooperate with the pressing block 604 to perform terminal pressing. The two ear plates 903 on both sides of the lower mold body 901 can be slidably installed into the interior of the upper and lower mounting plates 10 to facilitate the disassembly and replacement of different lower mold bodies 901.

[0023] like Figures 2-3 As shown, the upper mounting plate 602, the docking plate 605, and the lower mounting plate 10 are all L-shaped structures. The docking plate 605 is slidably connected to the inner cavity of the upper mounting plate 602, and the ear plate 903 is slidably connected to the inner cavity of the lower mounting plate 10. The lower mounting plate 10 is fixed on both sides of the upper side of the movable mounting base 7. The middle part of the lower mounting plate 10 and the middle parts of both sides of the lifting plate 601 are equipped with positioning connection components 11. The positioning connection components 11 include a threaded cylinder 1101, a threaded rod 1102, and a positioning rod 1103. The threaded cylinder 1101 is embedded in the middle part of the lower mounting plate 10 and the middle parts of both sides of the lifting plate 601, and the internal threads of the threaded cylinder 1101 are screwed with threads. The threaded cylinder 1101 has an integrally fixed positioning rod 1103 on its lower side. By rotating the threaded rod 1102 inside the threaded cylinder 1101, the position of the positioning rod 1103 can be adjusted, so that the positioning rod 1103 can be inserted into the positioning hole 12 of the mating plate 605 and the positioning hole 12 of the ear plate 903 respectively, realizing the tight installation of the upper mold body 603 and the lower mold body 901. The "L"-shaped limiting structure of the upper mounting plate 602 and the lower mounting plate 10 makes it difficult for the mating plate 605 and the ear plate 903 to come out and cannot move up, down, left, or right. The limiting effect of the positioning rod 1103 can further improve the tightness, making the installation convenient and the stability good.

[0024] like Figure 1 and Figure 3As shown, a position moving assembly 13 is installed on one side of the movable mounting base 7. The position moving assembly 13 includes a fixed frame 1301, a drive motor 1302, and a lead screw 1303. The drive motor 1302 is installed on the outer side of the fixed frame 1301, and the lead screw 1303 is rotatably mounted inside the fixed frame 1301. The position moving assembly 13 also includes a moving sleeve 1304 and a connecting block 1305. The moving sleeve 1304 is sleeved on the outer side of the lead screw 1303. 4. The inner wall of the fixed frame 1301 is slidably connected. A connecting block 1305 is fixed on the upper side of the movable sleeve 1304, and the front side of the connecting block 1305 is fixedly connected to the movable mounting base 7. The drive motor 1302 facilitates the rotation of the lead screw 1303, thereby driving the movement of the movable sleeve 1304 on the outer side of the lead screw 1303. This allows the movable sleeve 1304 to drive the movable mounting base 7 and the pressing lower mold assembly 9 to move horizontally through the connecting block 1305, thereby correcting the alignment error. This ensures that the pressing area of ​​the terminal is precisely aligned with the upper pressing block 604, ensuring that the terminal is subjected to uniform force during pressing and avoiding local stress concentration or terminal cracking caused by uneven pressing. The sliding groove 8 of the movable mounting base 7 is slidably connected to the limiting protrusion 2, making the movement of the movable mounting base 7 smooth.

[0025] In summary, as Figures 1-3 As shown, the intelligent switch's live and neutral wire terminal crimping structure, when in use, can first install the corresponding upper mold body 603 and lower mold body 901. During installation, the two mating plates 605 on both sides of the upper mold body 603 are slidably installed into the interior of the upper mounting plate 602, and the two ear plates 903 on both sides of the lower mold body 901 are slidably installed into the interior of the upper and lower mounting plates 10. Then, by rotating the threaded rod 1102 inside the threaded cylinder 1101, the position of the positioning rod 1103 can be adjusted, so that the positioning rod 1103 can be respectively inserted into the positioning hole 12 of the mating plate 605 and the positioning hole 12 of the ear plate 903, realizing the tight installation of the upper mold body 603 and the lower mold body 901. The "L"-shaped limiting structure of the upper mounting plate 602 and the lower mounting plate 10 makes it difficult for the mating plate 605 and the ear plate 903 to come out and cannot move up, down, left, or right. The limiting effect of the positioning rod 1103 can further improve the tightness, making installation convenient and with good stability.

[0026] After long-term use, the lower mold body 901 may experience slight misalignment, causing a centering deviation between the upper and lower molds. In this case, the drive motor 1302 can drive the lead screw 1303 to rotate, thereby moving the outer movable sleeve 1304 of the lead screw 1303. This causes the movable sleeve 1304 to move horizontally through the connecting block 1305, moving the movable mounting base 7 and the pressing lower mold assembly 9, thus correcting the centering error and ensuring that the crimping area of ​​the terminal is precisely aligned with the upper pressing block 604. This ensures that the terminal is subjected to uniform force during crimping and avoids local stress concentration or terminal cracking caused by misalignment. The sliding groove 8 of the movable mounting base 7 and the limiting protrusion 2 are slidably connected, making the movable mounting base 7 move smoothly. Then, the lower mold body 901 and the pressing groove 902 cooperate with the pressing block 604 to crimp the terminal. Finally, the cylinder 4 and the piston rod 5 drive the upper mold body 603 and the pressing block 604 to lift and lower, so that they can crimp the neutral and live wire terminals of the smart switch. This completes the use process of the smart switch neutral and live wire terminal crimping structure.
