Abstract
The invention discloses a magnet ring choking coil. The magnet ring choking coil comprises a magnet ring and a varnished wire wound around a magnetic core and is characterized in that the magnetic core is made of a T106-52 powdered iron core magnet ring. The method for producing the magnet ring choking coil comprises the steps of wire breaking, wire wrapping, forming, pin shearing, tin coating, pin cutting, pressure resistance testing, external examination, detection and packaging. The varnished wire is wound around the magnetic core by 16-18 mm. According to the magnet ring choking coil, required large current can be obtained on the premise that the size of the magnetic core is not increased, inductance can be as low as 140 uH min, and resistance does not exceed 0.04 ohm.
Description
Technical field
The present invention relates to choke technical field, be specifically related to a kind of magnet ring choke.
Background technology
Choke, as the core of choke, is anti-inductive coil of gripping alternating current, utilizes coil reactance and the proportional relation of frequency, can control high-frequency ac current, low frequency and direct current are passed through.It stops alternating component, only allows the inductance element that direct current passes through.Common choke structure and winding process are all comparatively simple, and leakage field is large, and distributed capacitance is little, and inductance value is little, and frequency characteristic difference and DC impedance are without lifting, and efficiency is low and do not reach complete machine decrease of noise functions.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides the large and a kind of magnet ring choke that resistivity is little of a kind of inductance value.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of magnet ring choke, comprise magnet ring and be wound in the enamelled wire on magnetic core, described magnetic core is ferrocart core magnet ring, the material of described magnetic core is T106-52 ferrocart core magnet ring, it has following technical process: broken string, coiling, shaping, cut pin, ward off tin, cutting, withstand voltage, test, outer inspection, packaging after inspection, the described enamelled wire width be wound on magnetic core is 16-18mm.
Further, draw after a circle again after during described coiling, ending line moves corresponding surface to from magnetic core top.
Further, the external diameter of described magnetic core after enamelled wire reeled is no more than 33mm.
Further, the initial and tail sections of described enamelled wire all reserves 5.2 ~ 6.8mm, and stitch does not weld part and is no more than 0.5mm.
Structure of the present invention is simple, and the prerequisite that a kind of magnet ring choke of gained can not increase at magnetic core size is issued to required big current, and the most I of its inductance reaches 140uH min, and resistance is maximum is no more than 0.04 Ω.Withstand voltage, can 1250VAC/2mA/min be reached between L-core.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is magnetic core, and 2 is enamelled wire.
