With the development of the electronics industry, the application scope of terminal blocks is becoming more and more extensive, and the types are also increasing. In addition to PCB board terminals, the most widely used ones also include hardware terminals, nut terminals, spring terminals, etc. Generally, when two terminal blocks are connected, by screwing a bolt, two power connection pieces are brought closer to each other, so that the two terminal blocks on the two power connection pieces are in contact to complete power connection. However, there are still the following defects:

[0003] When making the terminal block contact and connect electricity, it is necessary to manually tighten the bolt for connection, making the connection rather troublesome. Summary of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1, given by Figures 1-5 The present utility model relates to an automatic riveting device for a wiring terminal, including two electric connection pieces 1 and a wiring terminal 2 arranged on one side where the two electric connection pieces 1 are close to each other, and an automatic riveting assembly 3 is installed on the outer sides of the two electric connection pieces 1;

[0026] The automatic riveting assembly 3 includes a bottom plate 301 which is located below the lower power connection piece 1. A guiding column 302 is fixedly installed at the top end of the bottom plate 301. Side plates 303 are symmetrically installed at the top end of the bottom plate 301. The two side plates 303 are symmetrically arranged on both sides of the guiding column 302. A top plate 304 is fixedly installed at the top end of the side plate 303. Both power connection pieces 1 are slidably installed on the outer side of the guiding column 302. Card slots 308 are equiangularly formed on the outer wall of the guiding column 302. A pressing ring 309 is slidably installed on the outer side of the guiding column 302. The pressing ring 309 is located above the upper power connection piece 1. A longitudinal guiding rod 305 is installed between the bottom plate 301 and one of the top plates 304. Transverse plates 310 are symmetrically installed on both sides of the pressing ring 309. One of the transverse plates 310 is slidably connected to the longitudinal guiding rod 305. A screw rod 306 is rotatably installed between the bottom plate 301 and the other top plate 304. The top end of the screw rod 306 is fixedly connected to the output shaft of a motor 307. The motor 307 is fixedly installed at the top end of the top plate 304. Both power connection pieces 1 are arranged below the pressing ring 309. When the motor 307 is started to rotate the screw rod 306 to drive the pressing ring 309 to move downward, thereby pushing the upper power connection piece 1 to move downward. After the two power connection pieces 1 approach each other, the two wiring terminals 2 come into contact for power connection. When the two wiring terminals 2 are in contact, the clamping rod 316 is inserted into the card slot 308 to improve the fixed power connection effect and facilitate use. An internal groove 311 is formed inside the pressing ring 309. One side of the internal groove 311 close to the screw rod 306 extends into the corresponding transverse plate 310. A communication groove 312 is formed on the transverse plate 310. The communication groove 312 runs through the transverse plate 310 from top to bottom and is connected to the internal groove 311. An internal plate 313 is movably installed inside the internal groove 311. A screw barrel 314 is installed on the internal plate 313. The position of the screw barrel 314 corresponds to the position of the communication groove 312. The screw barrel 314 is threadedly connected to the screw rod 306. Rod slots 315 are equiangularly formed on the inner wall of the internal groove 311 close to the guiding column 302. A clamping rod 316 is movably installed inside the rod slot 315. An end plate 317 is installed at one end of the clamping rod 316 located inside the internal groove 311. The other end of the clamping rod 316 contacts the outer wall of the guiding column 302. A transverse guiding rod 318 is installed on the inner wall of the internal groove 311. The transverse guiding rod 318 is slidably connected to the end plate 317. A connecting rod 319 is hinged to the top end of the end plate 317. The top end of the connecting rod 319 is hinged to the bottom wall of the internal plate 313. During the downward movement of the pressing ring 309, since the end of the clamping rod 316 contacts the outer wall of the guiding column 302, the internal plate 313 moves downward synchronously with the pressing ring 309. When the clamping rod 316 moves to a position corresponding to the card slot 308, the internal plate 313 moves downward relative to the pressing ring 309 and is inserted into the card slot 308 to facilitate fixation.

[0027] Working principle: During operation, first, when it is necessary to connect the wiring terminals 2 on the two power connection pieces 1 for power connection, the motor 307 is controlled to start, causing the screw rod 306 to rotate. The screw rod 306 is threadedly connected to the screw barrel 314 on the inner plate 313, causing the inner plate 313 to move downward. Since the bottom end of the inner plate 313 is connected to the clamping rod 316 through the connecting rod 319, and the end of the clamping rod 316 contacts the outer wall of the guiding column 302, the inner plate 313 cannot move downward relative to the corresponding pressure ring 309 at this time, but can also drive the pressure ring 309 to move downward together. When the pressure ring 309 moves downward, it pushes the upper power connection piece 1 downward until the wiring terminals 2 on the two power connection pieces 1 come into contact;

[0028] After the wiring terminals 2 on the two power connection pieces 1 are in contact, the clamping rod 316 moves to a position flush with the card slot 308 on the guiding column 302. Then, the inner plate 313 moves downward relative to the pressure ring 309, thereby pushing the clamping rod 316 toward the guiding column 302 through the connecting rod 319, causing the clamping rod 316 to be inserted into the card slot 308, thus fixing the two power connection pieces 1 and improving the power connection stability.
