Abstract

A winding aid for an annular iron core winding comprises: a stick body having a first end and a second end opposite to each other along the length direction, each having a notch at the first end and the second end, each notch providing positioning for the enameled wire when it is repeatedly wound along the length direction. Since the width of the stick body is smaller than the inner diameter of the annular iron core, the stick body can pass through the annular iron core, so that the several-meter-long enameled wire wound on the winding aid for the annular iron core winding can pass through the annular iron core at the same time, so as to assist the user to wind the annular iron core winding more easily.

Description

Winding aid for toroidal core windings

This invention relates to a toroidal iron core, and in particular to a winding aid of a toroidal iron core winding.

Ring core is a common type of core. When forming a winding, it is not easy to manually wind the enameled wire around the ring core. For example, when forming a winding with 100 turns, the length of the enameled wire required is about three meters, which is much longer than the length of the arm. It is difficult to repeatedly pass the enameled wire through the ring core, and it is difficult to control the position of the enameled wire on the ring core, resulting in uneven winding.

Therefore, the purpose of the present invention is to provide a winding aid for a ring-shaped iron core winding to assist the user to wind the ring-shaped iron core winding more easily.

The technical means adopted by the present invention to solve the problem of the prior art is to provide a winding aid for an annular iron core winding, comprising: a rod body having a first end and a second end opposite to each other along the length direction, each having a notch at the first end and the second end, each of the notches providing positioning for the enameled wire when it is repeatedly wound around the notch along the length direction, and the width of the rod body being smaller than the inner diameter of the annular iron core so as to be able to pass through the annular iron core.

In one embodiment of the present invention, a winding aid for an annular iron core winding is provided, wherein the first end is Y-shaped.

In one embodiment of the present invention, a winding aid for an annular iron core winding is provided, wherein the second end is Y-shaped.

In one embodiment of the present invention, a winding aid for an annular iron core winding is provided, wherein the rod body is a bent metal wire.

Through the technical means adopted by this invention, several meters of enameled wire taken from the enameled wire reel can be transferred to the winding aid of the ring-shaped iron core winding of this invention. Since the winding aid of the ring-shaped iron core winding can pass through the ring-shaped iron core, the several meters of enameled wire wound on the winding aid of the ring-shaped iron core winding can pass through the ring-shaped iron core at the same time, so as to assist the user to wind the ring-shaped iron core winding more easily. Furthermore, since it is easier to control the position of the enameled wire on the ring-shaped iron core, the winding is formed to be flat.

The following describes the implementation of the present invention based on Figure 1 and Figure 2. The description is not intended to limit the implementation of the present invention, but is an example of the implementation of the present invention.

As shown in FIG. 1 and FIG. 2 , a winding aid 100 of a ring-shaped iron core winding in an embodiment of the present invention includes: a rod body 1 having a first end 11 and a second end 12 opposite to each other along the length direction.

The rod body 1 has notches 111 and 121 at the first end 11 and the second end 12. Each notch 111 and 121 is used to provide positioning for the enameled wire W when it is repeatedly wound around the notches 111 and 121 along the length direction d1.

The width w1 of the rod body 1 is smaller than the inner diameter w2 of the annular iron core C so that the rod body 1 can pass through the annular iron core C.

The rod body 1 is a bent metal wire to form a rod-shaped profile. The metal wire can be a galvanized iron wire of American Wire Gauge (AWG) No. 16. Of course, in other embodiments, the metal wire can be other wire diameters and/or other materials.

As shown in FIG. 1 and FIG. 2, in the winding aid 100 of the ring-shaped iron core winding of the embodiment of the present invention, the first end 11 is Y-shaped and has a V-shaped notch 111, and the second end 12 is also Y-shaped and has a V-shaped notch 121. In other embodiments, the shapes of the notches 111 and 121 can be U-shaped, U-shaped, etc. The shape of the notch 111 of the first end 11 and the shape of the notch 121 of the second end 12 can also be different.

In this embodiment, a stabilizer 2 is further included, which surrounds and is fixed to the middle section of the stick body 1 to prevent the position of the metal wire of the stick body 1 from being misaligned.

By means of the above structure, several meters of enameled wire W taken off from the enameled wire reel can be transferred to the winding aid 100 of the ring-shaped iron core winding of the present invention. Since the winding aid 100 of the ring-shaped iron core winding can pass through the ring-shaped iron core C, the several meters of enameled wire W wound on the winding aid 100 of the ring-shaped iron core winding can pass through the ring-shaped iron core at the same time, so as to assist the user to wind the ring-shaped iron core winding more easily. Furthermore, since it is easier to control the position of the enameled wire on the ring-shaped iron core, the winding is formed to be flat.

The above description and explanation are only the description of the preferred embodiment of this creation. Those with common knowledge of this technology can make other modifications according to the scope of the patent application defined below and the above explanation. However, these modifications should still be for the creative spirit of this creation and within the scope of rights of this creation.
