Background

An inductor is a component that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, but has only one winding. The inductor has an inductance that only impedes the change in current. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. Inductors are also known as chokes, reactors, dynamic reactors.

The inductor is generally formed by winding a copper wire around a magnetic ring, and the general winding method is divided into close winding and space winding. In general, close winding is adopted in the medium and short wavelength range, but uniform space winding is adopted in an inductance coil used for a high-frequency resonance circuit, so that the distributed capacitance of the inductor is reduced, and the quality factor and the stability are higher.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a device for uniformly winding an inductor comprises a sleeve 1, wherein the sleeve 1 is a cylindrical cavity structure with an opening on the top surface, the bottom of the sleeve 1 is fixedly connected with a rotating shaft 2, a ring 5 is arranged on the inner bottom surface of the sleeve 1 and positioned on the outer side of the rotating shaft 2, and a magnetic ring clamping table 6 is formed between the ring 5 and the inner wall of the sleeve 1;

set up the through wires hole 3 that a plurality of is even, equidistance, encircle on the 1 periphery wall of sleeve, a wire winding groove 4 has all been seted up to the top of every through wires hole 3 corresponding, and the one end in every wire winding groove 4 all is linked together rather than corresponding through wires hole 3, and the other end in every wire winding groove 4 all communicates to 1 top surface opening part of sleeve.

In this embodiment, because the inductance coils for the high-frequency resonant circuit all adopt the uniform winding method, when the uniform winding method is used for the magnetic ring, firstly, the rotating shaft 2 is fixed on the bench vice, then the magnetic ring is sleeved into the magnetic ring clamping table 6 to start winding the magnetic ring, then the enameled wire passes through one threading hole 3 of the sleeve 1 and one winding groove 4 corresponding to the threading hole 3, then the enameled wire passes through the magnetic ring and is wound on the magnetic ring, when the first winding groove 4 is wound, the sleeve is rotated to the second winding groove 4 to the left, and the second winding is continued, so that the enameled wire is uniformly wound and distributed on the magnetic ring, the operation is simple, no technical requirement exists on the operation, and the production line is suitable for rapid production. It should be noted that the number of the winding slots 4 and the number of the threading holes 3 on the sleeve 1 are equal and corresponding, and the number of the winding slots 4 and the number of the threading holes 3 can be equally divided according to the diameter and the number of turns of the product.

Furthermore, each threading hole 3 is in a shape of a round rectangle.

In this embodiment, the through wires hole 3 of fillet rectangle makes things convenient for the enameled wire to pass, also is convenient for the staff simultaneously to carry out the wire winding operation.
