[0024] The present utility model provides two technical solutions:

[0025] Figures 1-4 The first implementation manner is shown: A current transformer that is easy to install includes a current transformer body 1, and an installation mechanism 2 is arranged at the rear side of the current transformer body 1 for conveniently installing and disassembling the current transformer body 1. The installation mechanism 2 includes:

[0026] The clamping component 21 is arranged at the rear side of the current transformer body 1 for installing and fixing the current transformer body 1. The clamping component 21 includes an installation box 211 movably installed at the rear side of the current transformer body 1. A limiting groove 212 and a connecting groove 216 are formed on the front side of the installation box 211. Two connecting rods 217 are movably installed inside the installation box 211. Clamping plates 214 are fixedly installed at the front ends of the two connecting rods 217. Clamping grooves 215 are formed on the opposite sides of the clamping plates 214. Limiting blocks 213 are fixedly installed at the rear sides of the clamping plates 214. A limiting component is arranged inside the installation box 211 to facilitate the disassembly and replacement of the current transformer body 1;

[0027] The reinforcement component 22 is arranged inside the current transformer body 1 to improve the stability of the current transformer body 1 after installation. The limiting component includes a sliding groove 2113 formed at the rear side of the inner cavity of the installation box 211. Two sliding blocks 2112 are slidably installed inside the sliding groove 2113. Two limiting rods 2114 are fixedly installed inside the sliding groove 2113. Springs 2111 are movably sleeved at the left and right ends of the two limiting rods 2114, and the positions of the springs 2111 can be limited by the two limiting rods 2114. Connecting plates 218 are movably hinged to the top surfaces of the two connecting rods 217, and the two connecting plates 218 are obliquely installed. A pressing plate 2110 is movably hinged to the top ends of the connecting plates 218. A communication groove 219 is formed on the top surface of the installation box 211. The left and right ends of the current transformer body 1 are closely attached to the inner sides of the clamping grooves 215. The front ends of the two connecting rods 217 movably penetrate through the inside of the connecting groove 216 and are fixedly installed at the rear sides of the clamping plates 214. The rear sides of the limiting blocks 213 are slidably installed inside the limiting groove 212, and the limiting blocks 213 can improve the movement stability of the clamping plates 214 through the limiting groove 212. The rear ends of the two connecting rods 217 are fixedly installed at the front sides of the two sliding blocks 2112. The left ends of the two limiting rods 2114 movably penetrate through the right sides of the two sliding blocks 2112 and are fixedly installed at the left side of the sliding groove 2113. The opposite ends of the springs 2111 are fixedly installed at one side of the two sliding blocks 2112. The ends of the springs 2111 far from the two sliding blocks 2112 are fixedly installed at one side of the sliding groove 2113. The elastic force of the springs 2111 can drive the two sliding blocks 2112 to move the two connecting rods 217 towards the opposite sides. At this time, the two connecting rods 217 will drive the clamping plates 214 to fix the current transformer body 1 through the clamping grooves 215. The top ends of the connecting plates 218 movably penetrate through the inside of the communication groove 219 and are movably hinged to the bottom surface of the pressing plate 2110. Pressing the pressing plate 2110 can drive the connecting plates 218 to press down and push the two connecting rods 217 away to facilitate the disassembly of the current transformer body 1.

[0028] By means of the provided connecting rod 217 and spring 2111, current transformer bodies 1 of different specifications can be adapted. During use, press the pressure plate 2110 to drive the connecting plate 218, causing the slider 2112 to move to the left and right sides. At this time, the slider 2112 will drive the connecting rod 217 to synchronously move the clamping plate 214. Then, place the current transformer body 1 between the clamping plates 214. Next, release the pressure plate 2110, and the elastic force of the installation box 211 will push the slider 2112 to drive the clamping plate 214 to clamp the current transformer body 1. At the same time, the left and right ends of the current transformer body 1 will be inserted into the inside of the card slots 215 to be clamped, which is convenient for installation and convenient to adjust to adapt to current transformer bodies 1 of different sizes, and has good practicability.

[0029] Figure 1 and Figures 3-4 The second embodiment is shown, and the main difference from the first embodiment is that: the reinforcement assembly 22 includes guide grooves 225 opened on the left and right sides of the inner cavity of the installation box 211. A reinforcement plate 223 is movably installed inside the installation box 211. An adjustment screw 221 is movably installed on the bottom surface of the reinforcement plate 223. A plurality of bumps 224 are fixedly installed on the top surface of the reinforcement plate 223, and the plurality of bumps 224 are linearly and evenly distributed on the top surface of the reinforcement plate 223. The friction between the fixed block 222 and the reinforcement plate 223 can be increased through the plurality of bumps 224. Fixed blocks 222 are fixedly installed on the bottom surfaces of both connecting rods 217. The bottom end of the adjustment screw 221 threadedly penetrates through the inside of the installation box 211 and extends to the bottom surface of the installation box 211. Both the left and right sides of the reinforcement plate 223 are slidably installed inside the guide grooves 225, and the lifting trajectory of the reinforcement plate 223 can be restricted through the guide grooves 225.

[0030] By means of the provided fixed blocks 222 and reinforcement plates 223, the stability of the device can be conveniently improved. During use, rotate the adjustment screw 221 to make the reinforcement plate 223 move upward through the guide grooves 225. Then, the reinforcement plate 223 will drive the bumps 224 to contact the bottom surface of the fixed block 222 to strengthen the fixation of the position of the connecting rod 217, prevent the current transformer body 1 from shaking, and improve the stability of the device.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-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.

[0032] In use, the user installs the installation box 211 at a suitable position, then presses the pressing plate 2110 to drive the connecting plate 218, causing the slider 2112 to move to the left and right sides. At this time, the slider 2112 will drive the connecting rod 217 to synchronously move the clamping plate 214. Then, the current transformer body 1 is placed between the clamping plates 214. Next, when the pressing plate 2110 is released, the elastic force of the installation box 211 will push the slider 2112 to drive the clamping plate 214 to clamp the current transformer body 1. At the same time, the left and right ends of the current transformer body 1 will be inserted into the inside of the card slot 215 and stuck. Then, rotate the adjusting screw 221 to make the reinforcing plate 223 move upward through the guiding groove 225. Next, the reinforcing plate 223 will drive the bump 224 to contact the bottom surface of the fixing block 222 to strengthen the fixing of the position of the connecting rod 217.
