Specific embodiment
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used to explain the utility model, but is not intended as the improper restriction to the utility model.
A kind of insulation inductance improved service life, including toroidal core 10 and coiling copper wire 20, toroidal core are metal
Powder core, the coiling copper wire are enamel covered wire, are separated between toroidal core and coiling copper wire by insulating paper layer 30；The insulation
Paper layer includes rectangular first insulating paper ontology 31, and two long sides of first insulating body are connected to respectively in trapezoidal transition
Side 32 and transition following 33；Transition top and transition are provided with the first fold line between the first insulating paper ontology respectively below
34；When the first insulating paper ontology is rolled into the first cylindrical body, transition top and the first fold line of transition lower edge are directed toward center of circle folding
It is 90 ° folded；Transition top and transition is allowed to be respectively formed seamless upper and lower disc below；Wherein the top edge of transition top is connected to
Two insulating paper ontologies 35 have the second fold line 36, the second insulating paper ontology edge between second insulating paper ontology and transition top
After second fold line is directed toward lower 90 ° of disc folding, the second cylindrical body with the first cylindrical-concentric is formed；Second insulating paper this bodily form
At the second cylindrical body connect with the lower disc that transition is formed below；Insulating paper layer is set to form internal cavities toroidal core is complete
Package does not leak；Coiling copper wire is wrapped in outside toroidal core outside insulating paper layer, forms insulation inductance.
