Description
Technical Field
The utility model relates to a super high magnetic conductivity filter magnetic core technical field.
Background
The filter magnetic core belongs to a magnetic ring, the size of the filter magnetic core is larger, but the small magnetic ring can not adjust the length and the size to achieve the purpose of modifying the electrical parameters, namely, the length of the magnetic core is modified to adjust the specification of the whole product. The micro-miniature magnetic ring is more difficult to grab and wind.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide super high permeability filter magnetic core, its simple structure, it is with low costs, improved wire-wound convenience, can modify the advantage of parameter through the magnetic core of the different quantity of stack.
The utility model adopts the technical proposal that:
a ultrahigh permeability filter core, comprising:
the fixing frame comprises a plastic screw and a round block, and one end face of the round block is connected with one end face of the plastic screw;
each magnetic ring is connected with the plastic screw rod in series in sequence;
and the plastic nut is arranged at the other end of the plastic screw rod, and one end of the plastic nut is contacted with the side end face of one of the magnetic rings.
And a first metal pin and a second metal pin are arranged on the round block.
The plastic screw is sleeved with two sealing rings, namely a first sealing ring and a second sealing ring, the first sealing ring is arranged between the round block and the magnetic ring, and the second sealing ring is arranged between the magnetic ring and the plastic nut.
Each magnetic ring is a circular magnetic ring, a through hole is formed in the middle of each magnetic ring, the diameter of the circumference of the outer side of each magnetic ring is 3.5mm, the diameter of each through hole is 1.8mm, and the thickness of each through hole is 1.5 mm.
According to different parameter requirements, different numbers of magnetic rings are overlapped, and then all the magnetic rings are fixed on the plastic screw rod through plastic nuts. The first sealing ring and the second sealing ring are used for buffering, and the magnetic ring is prevented from being extruded and cracked.
The utility model has the advantages that: simple structure, it is with low costs, improved wire-wound convenience, can modify the advantage of parameter through the magnetic core of different quantity of stack.
