DETAILED DESCRIPTION
[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See Figures 1-4 , this utility model provides two technical solutions:
[0024] First embodiment: A universal terminal fixing structure includes a terminal block 1, a coil 3 is movably mounted on the rear side of the terminal block 1, and a fixing mechanism 2 is provided on the outer side of the terminal block 1 to ensure that the connecting components of the reactor can be stably assembled together. The fixing mechanism 2 includes:
[0025] The terminal assembly 21 is provided on the outside of the terminal block 1 and is used to connect the reactor to the circuit;
[0026] The limiting component 22 is arranged on the front side of the terminal block 1 for fixing the lead-out wire of the coil 3. The limiting component 22 includes a U-shaped groove 228 opened at the left and right ends of the bottom surface of the front side of the terminal block 1, and an arc groove 222 is opened at the left and right ends inside the terminal block 1. A connecting groove 221 is opened on the front side of the arc groove 222, and an arc plate 223 is movably installed inside the arc groove 222. A handle 224 is fixedly installed on the front side of the arc plate 223. A clamping component is provided on the front side of the terminal block 1 to fix the position of the arc plate 223. The clamping component includes a slide groove 226 opened on the front side of the terminal block 1, and a slider 225 is movably installed on the left and right ends inside the slide groove 226. A connecting block 227 is fixedly installed on the front side of the slider 225. A spring 2211 is fixedly installed on the opposite side of the slide groove 226. An insert block 2210 is fixedly installed on the side of the slider 225 away from the spring 2211. The front end of the handle 224 can be movably passed through the interior of the connecting groove 221 and extended to the front side of the terminal block 1. Pulling the handle 224 can drive the curved plate 223 to rotate so that the U-shaped groove 228 is closed to limit the lead-out line. The front side of the slider 225 can movably pass through the interior of the sliding groove 226 and be fixedly installed on the rear side of the connecting block 227. One end of the inserting block 2210 can movably pass through the interior of the sliding groove 226 and extend to the interior of the slot 229. When the curved plate 223 rotates, when the slot 229 overlaps with the inserting block 2210, the elastic force of the spring 2211 will push the slider 225 to insert the inserting block 2210 into the interior of the slot 229 to fix the curved plate 223, which is convenient and quick.
[0027] The lead-out wire can be limited by the provided arc plate 223 and the plug block 2210. When in use, the lead-out wire is placed inside the U-shaped groove 228, and then the handle 224 is rotated to drive the arc plate 223 to rotate. When the arc plate 223 rotates, the slot 229 overlaps with the plug block 2210, and the elastic force of the spring 2211 pushes the slider 225 to insert the plug block 2210 into the slot 229 to fix the arc plate 223. At the same time, the arc plate 223 will close the U-shaped groove 228 so that the lead-out wire is located inside the U-shaped groove 228, avoiding loosening and falling off, thereby improving the stability of the connection and having good practicality.
[0028] The second embodiment is mainly different from the first embodiment in that: the terminal assembly 21 includes a vertical slot 211 opened on the left and right sides of the terminal block 1, a claw-shaped connecting terminal 212 is movably installed inside the vertical slot 211, a first oblique block 213 is fixedly installed on the front side of the claw-shaped connecting terminal 212, a second oblique block 215 is opened on the front side of the vertical slot 211, a horizontal slot 214 is fixedly installed on the bottom surface of the second oblique block 215, the top surface of the vertical slot 211 passes through the interior of the terminal block 1 and extends to the top surface of the terminal block 1, and the second oblique block 215 is away from the claw-shaped connecting terminal One side of the sub-block 212 passes through the interior of the terminal block 1 and extends to the outside of the terminal block 1. The front side of the claw-shaped connecting terminal 212 movably passes through the interior of the second oblique block 215 and extends to the front side of the terminal block 1. The claw-shaped connecting terminal 212 is conveniently disassembled and assembled through the vertical groove 211 and the second oblique block 215. The rear side of the first oblique block 213 is tightly attached to the front side of the claw-shaped connecting terminal 212, and the top surface of the horizontal groove 214 is tightly attached to the bottom surface of the claw-shaped connecting terminal 212. The claw-shaped connecting terminal 212 can be fixed by the first oblique block 213 and the horizontal groove 214.
[0029] The vertical slot 211 and the second oblique block 215 are provided to facilitate the removal and replacement of the claw-shaped connecting terminal 212. When in use, the claw-shaped connecting terminal 212 is inserted into the vertical slot 211, and the front side of the claw-shaped connecting terminal 212 is inserted into the second oblique block 215. At this time, the first oblique block 213 and the horizontal slot 214 can be used to tightly adhere to the outer side of the claw-shaped connecting terminal 212 to fix the claw-shaped connecting terminal 212. At the same time, this structure adapts to the mainstream claw-shaped connecting terminals 212 on the market. When the device has a malfunction and needs to be reworked, the claw-shaped connecting terminal 212 can be directly pulled out of the vertical slot 211 to replace the claw-shaped connecting terminal 212, which improves the rework efficiency and reduces the scrap rate of the product.
[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.
[0031] When in use, the employee inserts the claw-shaped connecting terminal 212 into the vertical slot 211, and the front side of the claw-shaped connecting terminal 212 will be inserted into the second oblique block 215. At this time, the claw-shaped connecting terminal 212 can be tightly attached to the outer side of the claw-shaped connecting terminal 212 through the first oblique block 213 and the horizontal slot 214. Then the employee fits the terminal block 1 on the surface of the wire-outlet side of the coil 3 and fixes the fixing mechanism 2 with tape. Then, the lead wire is placed into the U-shaped slot 228, and then the handle 224 is rotated to drive the arc plate 223 to rotate. When the arc plate 223 rotates, the slot 229 overlaps with the plug 2210, and the elastic force of the spring 2211 will push the slider 225 to make the plug 2210 inserted into the slot 229 to fix the arc plate 223. At the same time, the arc plate 223 will close the U-shaped slot 228 so that the lead wire is located inside the U-shaped slot 228, which is convenient and quick.
