Abstract
The utility model discloses a long service life and easy coiling's mutual-inductor iron core, iron core including the ring structure, the iron core is equipped with insulating cover for last, insulating cover is the ring structure, and this insulating cover includes outer lane and inner circle, all be equipped with the wire winding mouth that wire winding and interior outer coil opening of being convenient for align each other in outer lane and the inner circle, all be equipped with the chamfer on the wire winding mouth. The utility model discloses be equipped with insulating cover in the iron core both sides, and be equipped with the coiling mouth at the inner circle of insulating cover and outer lane edge, not only can prevent that the copper line is direct and the iron core contact is easy disconnected, still easily the coiling and guaranteed that the copper line coiling all transports and improve coiling efficiency.
Description
Technical Field
The utility model relates to a mutual-inductor technical field, concretely relates to long service life and easy coiling's mutual-inductor iron core.
Background
The mutual inductor is also called instrument transformer, and is a general name of current mutual inductor and voltage mutual inductor. The high voltage can be changed into low voltage, and the large current can be changed into small current for measuring or protecting the system. Wherein the mutual coil is an indispensable component of the transformer.
Most of the transformers on the market are directly formed by winding iron cores and copper wires. Because copper line coiling need be in the same place copper line stretch-out tightly winding, and the iron core is all approximate right angle all around by the direct coiling shaping of steel sheet, and the direct easy emergence fracture of copper line and port piece contact friction to make whole mutual-inductor coil scrap and increased the cost, and if coil coiling inhomogeneous then can make the magnetic field that the coil produced when the coiling product property ability is influenced.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to solve the problem, the utility model provides a simple structure can not break the mutual-inductor iron core of copper line and easy coiling.
(II) technical scheme
The utility model discloses a long service life and easy coiling's mutual-inductor iron core, iron core including the ring structure, the iron core is equipped with insulating cover for last, insulating cover is the ring structure, and this insulating cover includes outer lane and inner circle, all be equipped with the wire winding mouth that wire winding and interior outer coil opening of being convenient for align each other in outer lane and the interior circle, all be equipped with the chamfer on the wire winding mouth.
In some embodiments, the winding ports are disposed at an axially outer side of the outer and inner rings.
In some embodiments, the left side and the right side of the iron core are provided with insulating sleeves.
In some embodiments, the outer surface of the inner ring is in fit connection with the inner surface of the iron core, and the inner surface of the outer ring is in fit connection with the outer surface of the iron core.
(III) advantageous effects
Compared with the prior art, the utility model, it has following beneficial effect: insulating sleeves are arranged on two sides of the iron core, and winding openings are formed in the edges of the inner ring and the outer ring of each insulating sleeve, so that copper wires can be prevented from being directly contacted with the iron core and being easily broken, the copper wires can be easily wound, and the winding efficiency can be improved by ensuring that the copper wires are wound uniformly.
