Description

Technical Field

[0001] The utility model belongs to the technical field of voltage stabilizers, and in particular relates to a mounting structure of a voltage stabilizer annular coil. Background Art

[0002] The toroidal coil of a voltage stabilizer is relatively bulky, so its installation method is very important, requiring comprehensive consideration of stability, insulation, and heat dissipation. In the prior art, the toroidal coil of a voltage stabilizer is typically fixed directly to a flat baseplate, with the bottom of the toroidal coil isolated from the baseplate using insulating paper. This installation method lacks an anti-shift mechanism on the baseplate, and during use, the toroidal coil will inevitably shake due to vibration and other reasons, affecting the performance of the voltage stabilizer. There is no gap between the bottom of the toroidal coil and the baseplate, and it relies on insulating paper for isolation from the baseplate, resulting in poor insulation performance and poor heat dissipation, which also affects the performance of the voltage stabilizer. Summary of the Invention

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a mounting structure for a toroidal coil of a voltage stabilizer.

[0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: a mounting structure of a toroidal coil of a voltage stabilizer, comprising a mounting frame, a bottom plate being provided at the bottom of the mounting frame, the toroidal coil being mounted and fixed on the bottom plate, an upward boss being provided in the middle of the bottom plate, an insulating pad being provided on the boss, an insulating paperboard being provided on the insulating pad, the toroidal coil being fixed on the boss via a plurality of long screws, the insulating pad comprising a flange base and a vertical convex ring, the vertical convex ring being adapted to the boss, and after assembly, the lower port of the middle hole of the toroidal coil being adapted to the vertical convex ring, the vertical convex ring being tightly fitted on the boss, the through-hole edge in the middle of the insulating paperboard being pressed against the flange base, the flange base being pressed against the bottom plate, and a gap being formed between the insulating paperboard and the bottom plate.

[0005] Preferably, the boss is formed by punching the bottom plate upward as a whole, the insulating pad is made of rubber or silicone, and the insulating paperboard is made of DMD insulating paper.

[0006] Preferably, the height of the boss is 5-10mm, the vertical convex ring is 3-5mm higher than the boss, the outer diameter of the flange base is 15-25mm larger than the diameter of the hole in the annular coil, the outer diameter of the insulating paperboard is 10-15mm larger than the outer diameter of the annular coil, and the thickness of the insulating paperboard is 0.1-0.3mm.

[0007] Preferably, the insulating paperboard is coated with insulating thermally conductive adhesive.

[0008] Preferably, a plurality of mutually spaced convex teeth and grooves are provided on the edge of the through hole in the middle of the insulating paperboard, the tooth tops of the convex teeth are adapted to the vertical convex ring, and the base circle diameter of the groove bottom is smaller than the outer diameter of the flange base. After assembly, the edge of the through hole in the middle of the insulating paperboard is pressed against the flange base, and the tooth tops of the convex teeth are pressed against the vertical convex ring.

[0009] Preferably, the number of the protruding teeth and the grooves is 3-6, and the protruding teeth are square teeth.

[0010] The present invention features an upward-facing boss in the center of the base plate, which is equipped with an insulating pad. The insulating pad is then topped with insulating cardboard. The toroidal coil is secured to the boss via several long screws. This allows the toroidal coil to be positioned on the base plate, preventing it from shaking due to vibrations and other factors. After assembly, a gap is formed between the insulating cardboard and the base plate. The insulating cardboard is coated with an insulating, thermally conductive adhesive. The insulating cardboard and the gap provide dual electrical isolation, ensuring stable and reliable insulation performance. This also significantly facilitates heat dissipation and improves the performance of the voltage regulator. The through-hole edge in the center of the insulating cardboard is provided with several spaced-apart protrusions and grooves. After assembly, the tops of the protrusions rest against the vertical protrusions, facilitating the positioning of the insulating cardboard on the insulating pad. Furthermore, since the insulating pad is made of a soft material such as rubber or silicone, the protrusions sink into the flange base after assembly. The bottom of the toroidal coil directly contacts the flange base through the grooves, creating a high friction force between the two, further preventing the toroidal coil from shaking. Therefore, the present invention features a simple structure and a rational design. BRIEF DESCRIPTION OF THE DRAWINGS
