DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] like Figures 1 to 3 As shown, an isolated magnetic ring inductor includes a rectangular insulating base 1 and a circular magnetic ring 5. An insulating stand 2 perpendicular to the insulating base 1 is arranged on the top of the insulating base 1, and the cross section of the insulating stand 2 is "T" shaped.

[0021] A circular insulating support ring 3 is provided on one side of the insulating stand 2 , and the central axis of the insulating support ring 3 is perpendicular to a side of the insulating stand 2 close to the insulating support ring 3 .

[0022] The magnetic ring 5 is installed on the insulating support ring 3 , and the outer diameter of the insulating support ring 3 is equal to the inner diameter of the magnetic ring 5 , so that the magnetic ring 5 is just sleeved outside the insulating support ring 3 .

[0023] A vertical insulating isolation plate 4 is arranged in the insulating support ring 3 , and the insulating isolation plate 4 is perpendicular to a side of the insulating stand 2 close to the insulating support ring 3 .

[0024] Two groups of coils 6 are wound around the magnetic ring 5 and the insulating support ring 3 , and the insulating isolation plate 4 is located between the two groups of coils 6 .

[0025] The insulating stand 2 is provided with two left-right symmetrical first threading holes 7, the insulating seat 1 is provided with two left-right symmetrical second threading holes 8 and two left-right symmetrical third threading holes 9, one end of the coil 6 passes through the first threading hole 7 and the second threading hole 8 in sequence, and the other end of the coil 6 passes through the third threading hole 9.

[0026] In order to improve the stability of the magnetic ring 5 and prevent the insulating stand 2 and the insulating support ring 3 from deformation or tearing, an insulating support block 10 is further provided at the top of the insulating seat 1. The top of the insulating support block 10 is an arc surface matching the outer side surface of the magnetic ring 5.

[0027] The corners at both ends of the outer wall of the magnetic ring 5 are rounded, and the corners at both ends of the inner wall of the insulating support ring 3 are rounded, which increases the bending radius of the coil 6 at the corners at both ends of the outer wall of the magnetic ring 5 and the corners at both ends of the inner wall of the insulating support ring 3, reduces the stress of the coil 6, and prevents damage to the surface of the coil 6.

[0029] An insulating seat, an insulating stand, an insulating support ring and an insulating isolation plate are integrally provided. Two groups of coils are wound around the insulating support ring and the magnetic ring. The insulating isolation ring is located between the two groups of coils to isolate the two groups of coils. The insulating isolation plate does not require gluing and is firmly connected to the insulating support ring.
