[0020] Base 5, frame 2 arranged at the top center of base 5, winding 3 wound on the surface of frame 2, magnetic core 1 fixed outside winding 3, and multiple output pins 7 arranged at the bottom of base 5;

[0021] A magnetic ring inductor 4 is provided on the top of the base 5. The winding 3 is wound with copper wire and is divided into a primary coil and a secondary coil. The magnetic ring inductor 4 is an inductor inserted into the secondary coil. The model of the magnetic ring inductor 4 is 038125-15UH and is used to monitor the current at the output end.

[0022] A reinforcement protection structure 6 is provided at the bottom of the base 5. The reinforcement protection structure 6 includes a base strip 61 installed on the bottom surface of the base 5 and a plurality of protection support sleeves 62 fixed on the bottom surface of the base strip 61 corresponding to the output pins 7. The output pins 7 pass through the base strip 61, and the protection support sleeves 62 are sleeved on the top surface of the output pins 7, which can support and protect the roots of the output pins 7 to prevent the roots of the output pins 7 from bending or damage due to external forces.

[0023] Among them, the reinforcement protection structure 6 also includes side clamps 63 movably installed on the two end surfaces of the base strip 61, the top of the side clamp 63 extends to the side of the base 5, and a triangular clamping block 68 is fixed on the inner side of the top of the side clamp 63, and rectangular clamping grooves 69 corresponding to the triangular clamping blocks 68 are provided on both side surfaces of the base 5. The triangular clamping blocks 68 are embedded in the rectangular clamping grooves 69 to achieve stable positioning of the base strip 61 and complete the stable installation of the base strip 61 and the protective support sleeve 62. The reinforcement protection structure 6 also includes inner slide grooves 64 opened at both ends of the base strip 61, springs 65 and inner sliders 66 installed in the inner slide grooves 64, and connecting rods 67 fixed on the side of the inner slider 66, and the ends of the connecting rods 67 pass through the end surfaces of the base strip 61 and are fixed to the side clamps 63, so that The side card plate 63 can be smoothly pulled at the end of the base strip 61, and in daily use, under the push of the spring 65, the inner slider 66 will press the side card plate 63 to the side of the base 5 through the connecting rod 67, ensuring that the triangular card block 68 can be stably stuck in the rectangular card groove 69, thereby achieving stable installation of the base strip 61. If the reinforced protective structure 6 is to be removed later, it is only necessary to pull the side card plate 63 to the side so that the connecting rod 67 pulls the inner slider 66 and the spring 65 is gradually compressed, so that the side card plate 63 can move the triangular card block 68 out of the rectangular card groove 69, and the limit on the base strip 61 can be released. At this time, the base strip 61 can be moved down and slide down from the bottom end of the output pin 7 with the protective support sleeve 62, thereby achieving rapid removal of the base strip 61 and the protective support sleeve 62.

[0024] One end of the spring 65 abuts against the inner wall of the inner sliding groove 64 , and the other end of the spring 65 abuts against the side surface of the inner sliding block 66 .

[0026] The inner diameter of the protective sleeve 62 is adapted to the diameter of the output pin 7 , so that the protective sleeve 62 can be smoothly sleeved on the output pin 7 .
