Abstract
The utility model discloses an anti-interference inductor with long service life. The shortcomings that an existing inductor is small in insulation resistance, mutual interference exists, friction of winding turns is large during high-frequency working, and service life is short, and the like are overcome. A protective layer is arranged on the surface of an inductor body. The anti-interference inductor with the long service life is used in electronic products such as computers and mobile phones, the insulation resistance between the inductor and peripheral electronic components is increased, mutual interference of electricity, magnetism and heat is small, friction of winding turns during high-frequency working is small and low, and the service life in prolonged by 3-5 years.
Description
Technical field
The utility model relates to a kind of electronic component, is specially a kind of anti-interference long-life inductor.
Background technology
Also have with the insulation resistance of peripheral electron element littlely under the existing inductor use state, also have the phase mutual interference of electricity, magnetic, heat, during high frequency operation the friction of winding turns many, the deficiency such as useful life is long.
The utility model content
The purpose of this utility model provides a kind of anti-interference long-life inductor for above-mentioned deficiency exactly, and the insulation resistance of it and peripheral electron element increases, and the phase mutual interference of electricity, magnetic, heat is few, during high frequency operation the friction of winding turns less and light, the prolongation in useful life.
For achieving the above object, the technical solution of the utility model is that this anti-interference long-life inductor comprises the inductor body that has magnet, is wound on the winding on this magnet, is provided with overcoat on the surface of described inductor body.
Part on the surface of described inductor body is provided with the PVC overcoat.
The utility model is provided with overcoat on the surface of described inductor body, further the part (usually in the part adjacent with other electronic components) on the surface of described inductor body is provided with the PVC overcoat, improved the insulation resistance with the peripheral electron element, few with the phase mutual interference of the electricity of peripheral electron element, magnetic, heat, the friction of winding turns less and gently during high frequency operation, and the body top and the bottom there are not overcoat, make the body good heat dissipation and don't pass to peripheral cell, overcoat also plays the fixation of winding inter-turn.
The utility model is used for the electronic products such as computer, mobile phone, increases with the insulation resistance of peripheral electron element, and the phase mutual interference of electricity, magnetic, heat is few, during high frequency operation the friction of winding turns less and gently, result of the test shows that the utility model prolongs 3-5 useful life.
Description of drawings
This accompanying drawing is the utility model cross sectional representation with toroidal magnet.
Among the figure, 1, magnet, 2, winding, 3, overcoat.
Embodiment
As shown in the figure, the anti-interference long-life inductor of the utility model, comprise the inductor body that has magnet 1, is wound on the winding 2 on this magnet 1, magnet 1 is annular, winding 2 is wound on this toroidal magnet 1, is provided with PVC overcoat 3 at the outer surface (namely with respect to the Outboard Sections adjacent with other electronic components) of this inductor body.This PVC overcoat 3 is in the outside of outside winding.
Claims (2)
1. anti-interference long-life inductor, comprise have magnet (1), be wound on the inductor body of the winding (2) on this magnet (1), it is characterized in that, be provided with overcoat (3) on the surface of described inductor body.
