[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a tool-free terminal block for quick wiring, including a terminal block body 1, a plurality of wiring cavities 3 on the terminal block body 1, a quick-connect wiring mechanism 2 inside each wiring cavity 3, and a protective mechanism 4 at the end of the terminal block body 1. Cables can be quickly wired through the quick-connect wiring mechanism 2 without the need for tools, effectively improving the convenience of use.

[0024] The quick-connect wiring mechanism 2 includes a base 201, a pressure block 202 on the top of the base 201, and a conductive block 203 fixedly connected to the base 201. The base 201 is fixedly installed inside the wiring cavity 3. The conductive block 203 is electrically connected to the interface end of the terminal block body 1 through a wire, so that the conductive block 203 can make contact with the wiring cable and enable the wiring cable to be energized with the interface end of the terminal block body 1. A movable column 204 is fixedly connected to the top of the pressure block 202. A guide groove 205 is opened on the movable column 204, and a fixing frame 206 is provided on the outside of the movable column 204. A guide slider 207 is fixedly connected to the fixed frame 206. The fixed frame 206 is fixedly installed inside the wiring cavity 3. The guide groove 205 matches the guide slider 207. The fixed frame 206 is slidably connected to the movable column 204, allowing the movable column 204 to move up and down along the fixed frame 206. A first spring 208 is provided on the top of the guide slider 207. The top end of the first spring 208 abuts against the inner top surface of the movable column 204, and the bottom end of the first spring 208 abuts against the guide slider 207, so that the first spring 208 can be used to move the guide slider 207 back to its original position. At the top of the movable column 204, a contact wheel 209 is installed. A rotating wheel 210 is located on the top of the contact wheel 209. The rotating wheel 210 is rotatably connected to the inner wall of the terminal block body 1, and a portion of the rotating wheel 210 extends out of the terminal block body 1, allowing it to rotate. An arc-shaped block 211 is fixedly connected to the bottom surface of the rotating wheel 210, and a connecting seat 212 is fixedly connected to the top surface of the rotating wheel 210. A movable rod 213 is located on one side of the connecting seat 212, and a limit block 214 is fixedly connected to the end of the movable rod 213. A second spring 215 is located on one side of the limit block 214. The limiting block 214 is slidably connected to the inner wall of the connecting seat 212, which can guide the movement of the movable rod 213. The second spring 215 is set between the limiting block 214 and the inner wall of the connecting seat 212, so that the limiting block 214 can be reset by the second spring 215, and at the same time, it can prevent the limiting block 214 from moving easily. A T-shaped limiting frame 216 is provided on one side of the rotating wheel 210. The T-shaped limiting frame 216 is fixed on the terminal block body 1, so that the movable rod 213 can be limited by the T-shaped limiting frame 216 to prevent it from moving upward, thereby pressing the wiring.

[0025] Please see Figure 1 and Figure 5 The protective mechanism 4 includes a protective plate 401. Multiple elastic retaining balls 402 are fixedly connected to one side surface of the protective plate 401. Multiple retaining slots are opened at the end of the terminal block body 1. An installation groove is opened on the protective plate 401. A sealing ring 403 is fixedly installed inside the installation groove. By inserting the sealing ring 403 into the installation groove and then inserting the elastic retaining balls 402 into the groove, the protective plate 401 can be secured to the end of the terminal block body 1, thereby protecting the interface end of the terminal block body 1 and preventing foreign objects from entering when idle.

[0026] During operation, the wire is placed on the conductive block 203, and then the movable rod 213 is rotated downwards. The rotation of the movable rod 213 drives the rotating wheel 210 to rotate, which in turn drives the arc block 211 to rotate. The arc block 211 uses its own arc surface to push the contact wheel 209 downwards. The movement of the contact wheel 209 drives the movable column 204 to move, which in turn drives the pressure block 202 to move, pressing the pressure block 202 onto the conductive block 203 and tightening the wire. Then, the movable rod 213 is pulled outwards, compressing the second spring 215 and allowing the movable rod 213 to move to the bottom of the T-shaped limit frame 216. After the movable rod 213 has moved into place, it is pushed into the T-shaped limit frame 216. The second spring 215 prevents the movable rod 213 from coming out, allowing for quick wiring of the cable without the need for tools, effectively improving ease of use.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
