The object of the invention is to be achieved through the following technical solutions:
A kind of magnetic screen inductance element manufacture method, comprises the steps:
Material preparation process: material comprises semi-finished product and the magnetic sleeve pipe of winding around in the middle part of I-type core, the external diameter that described magnetic sheath bore and semi-finished product contain coiler part adapts, the length of magnetic sleeve pipe wraps semi-finished product coiler part, and described I-type core two outer end is covered with silver coating;
Sleeve pipe socket step: magnetic sheath pipe box is connected on semi-finished product, just in time wraps half-finished coiler part;
Heating steps: the inductance element that cover connects magnetic sheath pipe is placed in heater and carries out heat treated, heating-up temperature is 125 DEG C ± 10 DEG C, heating time is: 25Mins ± 10Mins;
Cooling step: after the inductance element after heating is taken out, carry out cooling processing, after temperature reaches natural temperature, namely become finished product magnetic screen inductance element.
Technical scheme of the present invention also comprises a kind of magnetic screen inductance element, described magnetic screen inductance element is according to above-mentioned manufacture method manufacture, described magnetic screen inductance element comprises I-type core, be wound in the coil in the middle part of I-type core, be located at the silver coating of I-type core two outer end, be socketed on the magnetic sleeve pipe of coil outer, described magnetic sleeve pipe both ends are adjacent with I-type core end.
By the technical scheme of the invention described above, the present invention is very effective solves the problems such as existing product rate of finished products is low, manufacturing cost is high, and it is simple that magnetic screen inductance element manufacture method of the present invention has technique, and cost is low; Manufactured magnetic screen inductance element has the successful that structure is simple, shield magnetic, the features such as long service life.
