Description
Technical field
The utility model is related to electronic technology field, more particularly to a kind of novel magnetic ring structure.
Background technology
Absorb magnet ring, also known as ferrite bead, abbreviation magnet ring.It is common anti-interference element in electronic circuit, for
High-frequency noise has good inhibiting effect, is generally made using Ferrite Material.Magnet ring has different resistances at different frequencies
Anti- characteristic, generally the impedance very little in low frequency, when the impedance that signal frequency increases magnet ring performance drastically increases.It is equally known that
Signal frequency is higher, easier to radiate and (to buy good computer housing to be also intended to reduce electromagnetic leakage), and general letter
Number line is all not no shielded layer, then these signal wires just at good antenna, receive it is various mixed and disorderly in ambient enviroment
High-frequency signal, and these Signal averagings are on the signal transmitted originally, or even the useful signal transmitted originally can be changed.So exist
Under magnet ring effect, normal useful signal is set to pass through well, and passing through for high-frequency interferencing signal, Er Qiecheng can be inhibited well
This is cheap.
Existing magnet ring enameled wire is exposed outside, is subject to damage, and thus needs a kind of magnetic possessing shell protection
Ring.
Application No. is a kind of 201621222102.9 utility model patents to disclose a kind of magnet ring, including protective case lid and shield
Shell block is welded and fixed between the protective case lid and protective case seat, and junction offers outlet hole；The protective case lid and protective case seat are
Circular ring shape, middle part offer magnet ring hole, and magnetic core is equipped in the cavity of protective case lid and protective case seat, enameled wire is wound on magnetic core；
The enameled wire both ends are respectively connected with lead, and lead is pierced by by outlet hole.This magnet ring is improved on the original basis,
It is simple in structure, fastness is increased after improvement, extends service life.
But this design magnetic core is easy to shake in shell, and magnetic core, abrasion paint are also easily destroyed while generating noise
Resistance paint on envelope curve be easy to cause enameled wire short circuit, more straight than the inner ring of magnetic core if the annular inner wall design by shell is larger
Diameter is big, and can give and cause assembly difficult when assembly, while there is also made when assembly since enameled wire and inner walls generate friction
The danger to fall off at resistance paint.
Utility model content
The utility model provides a kind of novel magnetic ring structure, can solve the problems, such as pointed in background technology.
A kind of novel magnetic ring structure, including：
Magnetic core, the magnetic core are ring-type, and cross section is the trapezium structure that lower part is inwardly collapsed；
Protection cap comprising lid and cushion are provided with screw thread platform on the lid, are circumferentially opened up on the screw thread platform
There are external screw thread, the cushion to be fixed on the lower surface of the screw thread platform；
Protecting seat comprising pedestal and sealing ring, the pedestal are ring-type, offer in the pedestal it is circumferential, be used for
The dovetail groove of the magnetic core is stored, the bottom of the dovetail groove is inwardly collapsed, and the top that the pedestal is located at the dovetail groove is opened
Equipped with thread groove, offered in the thread groove with the matched internal thread of the external screw thread, the pedestal is towards the protection
The accommodating groove of annular is offered on the end face of lid, the sealing ring is arranged in the accommodating groove, is opened up on the pedestal useful
In the outlet hole that receiving enameled wire passes through.
More preferably, the cushion is rubber pad.
The utility model provides a kind of novel magnetic ring structure, is matched using screw thread platform and thread groove, can be easily right
Protective shell is dismantled, and cricoid magnetic core is placed in dovetail groove, can be easily by magnetic core using the cushion in protection cap
It is accommodated in shell, and since cushion squeezes magnetic core, magnetic core not will produce shaking when in use.

The protection domain of utility model is not restricted by specific implementation.
As shown in Figures 1 to 5, a kind of novel magnetic ring structure that the utility model embodiment provides, including：
Magnetic core 30, the magnetic core 30 are ring-type, and cross section is the trapezium structure that lower part is inwardly collapsed；
Protection cap 20 comprising lid and cushion 22 are provided with screw thread platform 21 on the lid, on the screw thread platform 21
External screw thread circumferentially is offered, the cushion 22 is fixed on the lower surface of the screw thread platform 21；
Protecting seat 10 comprising pedestal and sealing ring 13, the pedestal are ring-type, offer in the pedestal it is circumferential,
Dovetail groove 11 for storing the magnetic core 30, the bottom of the dovetail groove 11 are inwardly collapsed, and the pedestal is located at described trapezoidal
The top of slot 11 offers thread groove 12, offered in the thread groove 12 with the matched internal thread of the external screw thread, it is described
Pedestal offers the accommodating groove of annular on the end face towards the protection cap 20, the sealing ring 13 is arranged in the accommodating groove
It is interior, the outlet hole passed through for accommodating enameled wire is offered on the pedestal.
Further, the cushion 22 is rubber pad.
The utility model provides a kind of novel magnetic ring structure, is matched, can be facilitated using screw thread platform 21 and thread groove 12
Protective shell is dismantled on ground, and cricoid magnetic core 30 is placed in dovetail groove 11, can be with using the cushion 22 in protection cap 20
Easily magnetic core 30 is accommodated in shell, and since cushion 22 squeezes magnetic core 30, magnetic core 30 not will produce when in use
It shakes.
