Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding method that can efficiently wind wires in a short time on a divided bobbin having a plurality of flanges and a plurality of winding grooves.

Generally, when constructing a coil with a large number of turns, a split bobbin provided with a plurality of flanges is used.

This is often used in the secondary winding of flyback transformers and the secondary coil of ignition units in combustion appliances. A conventional method for winding wire on this type of split bobbin is as shown in FIGS. 1 and 2.

That is, a plurality of flanges 2a to 2e are provided at regular intervals on the circumferential surface of the cylindrical body 1, winding crossover grooves 3a to 3d are provided in the flanges 2a to 2d, and terminal pins are provided in the flanges 2a and 2e at both ends. Taking as an example a split bobbin 6 having four winding grooves 5a to 5d formed by planting wires 4 and 4, first, the beginning of the winding of the conductor 7 to be wound is wound around the terminal pin 4 of the collar 2a and fixed. , connect the conductor 7 to the guard 2a
A predetermined amount of wire is wound in the winding groove 5a between the flanges 2a and 2b through the connecting groove 3a, and then a predetermined amount of wire is wound in the winding groove 5e between the flanges 2b and 2c through the connecting groove 3b of the brim 2b. Then, a predetermined amount of wire is wound in the winding groove 5d through the crossing groove 3d of the collar 2d, and the conductor 7 at the end of the winding is wound around the terminal pin 4 of the collar 2e.

After winding, the 7 parts of the conductive wire wound around the terminal pin 4 were soldered to complete the coil. In this method, the time required for winding is the time required for winding the wires 7 to the two terminal pins 4.
the winding time, the time required to pass through the four transfer grooves 3a to 3d, and the loss time required to reduce and stop the rotation speed of the winding machine in order to pass through the transfer grooves 3a to 3d, and then increase the rotation speed again. The total winding time required to apply a prescribed number of turns to the four winding grooves 5a to 5d takes a considerable amount of time, resulting in poor productivity.

The present invention seeks to eliminate the above-mentioned drawbacks of the prior art.

Embodiments of the present invention will be described below with reference to J in FIGS. 3 to 5.

First, FIG. 3 shows the structure of the split bobbin used in the present invention.

8 is a cylindrical body, and the outer peripheral surface of this cylindrical body 8 is provided with five flanges 9a to 9e at regular intervals.
It is configured to have four winding grooves 10a to 10d by a to 9e.

Moreover, the bridge grooves 11a, 11b,
11d is provided, and terminal pins 1 are provided on the collars 9a, 9c, and 9e.
2a, 12c, and 12e are planted, and a J-shaped wiring groove 13 is formed in the collar 9c extending from the terminal pin 12c to the winding groove 10c.

A method of winding wire using the divided bobbin 14 having such a configuration will be explained with reference to FIGS. 4 and 5. Independent conductor wires 15 and 16 are attached to the terminal pins 12a and 12c of the collars 9a and 9c, respectively.
The conductor 15 is passed through the outside of the collar 9a and guided into the winding groove 10a through the crossing groove 11a.
6 is guided to the winding groove 9c through the wiring groove 13 of the collar 9c, and the split bobbin 14 is rotated to simultaneously wind the winding grooves 10a and 10c. When this winding is completed, each conductor 1
5 leads to the winding groove 10b through the connecting groove 11b of the collar 9b, and the conductor 16 passes through the connecting groove 11d of the collar 9d to the winding groove 10d.
the winding groove 10b by rotating the split bobbin 14 again.
, 10d are simultaneously wound.

When this winding is completed, the end of the winding of the conducting wire 15 is wound around the terminal pin 12c of the collar 9d, and the end of the winding of the conducting wire 16 is wound around the terminal pin 12e of the collar 9e, thereby completing the winding work. Thereafter, the coil is completed by soldering the wound portions of the conductive wires 15 and 16 of the terminal pins 12a, 12c, and 12e.

According to the method of this embodiment, since the number of terminal pins 12c is increased, the time for winding the conducting wires 15 and 16 is increased;
The loss time required for transferring the windings of windings b and 12d and lowering, stopping, and raising the rotational speed of the winding machine for that purpose is halved, and the time for winding the four winding grooves 10a to 10d is also halved, making it extremely efficient. winding is possible.

Although the above embodiment describes a split bobbin with four winding grooves, a bobbin with an even number of winding grooves such as two, six, eight, etc. can be wound in the same manner. Even in the case of an odd number of wires, if the same method is used to separately wind one winding groove, the winding work can be considerably shortened.

As described above, the winding method of the present invention has advantages such as significantly shortening the winding work, improving productivity, and being extremely advantageous in reducing costs. It has great industrial value.
