Description

TECHNICAL FIELD The present invention relates to a winding part having a common terminal, and relates to a winding part to be used as a transformer, an inductance coil or the like.

“Prior Art” FIG. 3 shows an example of a circuit of a transformer 24 having a primary coil N ₁ as an input winding and a secondary coil N ₂ , a tertiary coil N ₃ and a quaternary coil N ₄ as output windings. Is shown.

This kind of transformer 24 is a pin-shaped first to 12-third
The bobbin to which the sixth terminal is fixed is set in the winding machine and wound.

First, the secondary coil N ₂ is wound by a winding machine that winds a wire rod having a wire diameter φ ₁ . That is, this first winding machine winds the winding start end portion to the third terminal 14, and then winds a predetermined number of windings from the winding start portion (illustration / mark) in the winding direction of the arrow 18, and the winding is performed. This wire is cut after the end portion is entangled with the fourth terminal 15.

Subsequently, the tertiary coil N ₃ is wound by the first winding machine that winds the same wire as the secondary coil N ₂ . That is, in this first winding machine, after winding the winding start end portion to the fifth terminal 16, the winding start portion (shown in the figure) moves in the same winding direction (arrow 19b) as the winding direction of the secondary coil N ₂ . After winding a predetermined number of turns and winding the end of the winding on the fourth terminal 15 common to the secondary coil N ₂ , the wire is cut.

Further, the quaternary coil N ₄ is a secondary or tertiary coil (N ₂ , N ₃ ).
It is wound by the first winding machine that winds the same wire rod as.

In other words, in this first winding machine, after winding the winding start end to the fifth terminal 16, the winding winding is wound in the same direction as the winding direction of the secondary and tertiary coils (N ₂ , N ₃ ) from the winding start (illustrated and marked). After winding a predetermined number of turns in the direction (arrow 20) and entwining the end of the winding with the sixth terminal 17, the wire is cut.

Finally, the above winding component is transferred to a second winding machine for winding a wire having a wire diameter φ ₂ , and the winding machine winds the primary coil N ₁ . That is, in the second winding machine, after winding the winding start end portion to the first terminal 12, the winding start portion (illustrated / marked) makes a predetermined number of windings in the winding direction of the arrow 21, and the winding end portion After the part is entangled with the second terminal 13, the wire is cut.

The coil end of each coil formed as described above is fixed to each terminal by soldering.

[Problems to be Solved by the Invention] In the case of the above-described transformer, the steps of winding the winding start end of the wire, winding the winding end of the wire, and cutting the wire are repeated every time each coil is formed. Be done. From this, when the winding of one coil is finished, the winding end part is twisted and cut, and the winding start end of the coil to be wound next is twisted. The winding operation of is stopped. In fact, such coil end processing requires a longer working time than winding, and the more the number of coils forming the winding, the more this working time is repeated, resulting in a longer total stop time of the winding machine. Therefore, this terminal treatment is a big problem in increasing the transformer production efficiency.

"Means for Solving the Problem" The present invention is intended to solve the above-mentioned problems, and at least two coils, one coil and the other coil formed in the same winding direction, are provided. In a winding component in which the winding start end or winding end of these coils are connected by a common terminal, one coil is wound in one direction to form a winding, and the winding end is locked to the common terminal. After that, an electric winding component including a common terminal having each coil in which the other coil is formed by continuously winding from the common terminal in another direction without cutting the winding material is proposed.

[Operation] After forming one coil, the winding end is locked to the common terminal. For example, tie it to a pin-shaped common terminal,
Or hook it.

Then, the other coil is wound without cutting the wire.

Therefore, since the coil end treatment when one coil is formed is completed in a single twisting or hooking time, as in the conventional one, the winding end portion is twisted, cut, and the next coil is cut. It is possible to provide an electric winding component with high production efficiency by significantly shortening the coil end processing time as compared with performing the bending of the winding start end.

[Examples] Next, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a circuit diagram showing an embodiment in which the present invention is applied to a transformer similar to the conventional example.

The transformer 11 of this embodiment is wound on a bobbin (not shown) as a bobbin, and the bobbin has 12 to 12 turns.
It is assumed that the first to sixth terminals consisting of 17 are fixed beforehand.

First, the bobbin is set in the first winding machine capable of winding a wire having a wire diameter φ ₁ . This first winding machine has a winding start end with a third terminal
After winding the wire in the winding direction of arrow 18 from the winding start portion (marked in the figure) to form a secondary coil N ₂ , the winding end portion is twisted to the fourth terminal 15. Here, the wire rod twisted to the fourth terminal 15 is transferred to the next winding without being cut.

That is, the wire rod twisted to the terminal 15 is drawn out as it is, and is wound a predetermined number of times from the winding start portion (marked with ◎ in the figure) in the winding direction of the arrow 19a, that is, in the direction opposite to the winding direction of the secondary coil N ₂ . And form a tertiary coil N ₃ . This coil
The winding end portion of N ₃ is entangled with the fifth terminal 16. Subsequently, the wire rod twisted to the fifth terminal 16 is not cut, but is drawn out as it is, and the wire rod is wound from the winding start portion (illustration / mark) in the winding direction of the arrow 20, that is, the same winding as the secondary coil N ₂ . A predetermined number of turns is wound in the winding direction (opposite to the winding direction of the tertiary coil N ₃ ) to form the quaternary coil N ₄ . The terminal end of the winding is the 6th terminal
Twist to 17 and cut at the end.

Next, the winding component is transferred to a second winding machine capable of winding a wire having a wire diameter of φ ₂ , and the primary coil N ₁ is wound in the winding direction of arrow 21 as in the conventional example.

The ends of each coil twisted to each terminal are fixed by soldering.

As described above, in this embodiment, the tertiary coil N ₃ has the fourth terminal 15
Winding a withdrawn wire in the direction opposite to the winding direction of the secondary coil N ₂ from formed but, in this manner, as in the tertiary coil N ₃ of the prior art, the winding starting end to the fifth terminal 16 The result is the same as when the coil is twisted and wound in the same direction as the winding direction of the secondary coil N ₂ .

In addition, in this embodiment, the secondary, tertiary, and quaternary coils (N ₂ ,
Although conducted in winding order of N _3, N _4), quaternary vice versa, tertiary, or may be coils in the order of the secondary coil _{(N 4, N 3, N} 2). In this case, the wire rod is wound on the sixth terminal 17, the winding is started, the wire is sequentially wound through the fifth terminal 16 and the fourth terminal 15, and finally the wire rod is wound on the third terminal 14 to cut the wire. Ends, but
The winding direction of each coil is opposite to the arrow direction shown. Further, after forming the primary coil N ₁ into a winding,
N ₂ , N ₃ , and N ₄ may be wound.

By the way, when the secondary to quaternary coils (N _{2 to} N ₄ ) are continuously wound with a thin wire, each coil may be disconnected from the fastening portion of each terminal 14 to 17. In such a case, it is preferable to reinforce the bent portion to the terminal by forming a double line.

Specifically, at the beginning of winding the secondary coil N ₂ , the wire is double-wired as shown in FIG. That is,
By rewinding around the two support pestle 22 and 23 with appropriate intervals, A ₁ , A ₂ and A ₃ can be rewound by _one rewinding.
Since there are three double wires, the double wire portion is wound on the third terminal 14 as the winding start end portion, and then the secondary coil N ₂ is formed. Second when the winding of the secondary coil N ₂ is approaching the end
In the same manner as the figure, a double wire is formed and entangled with the fourth terminal 15, and further, in the same manner as above, the fifth terminal 16 and the sixth terminal 17 are entangled with the double wire portion formed by the method of FIG. Aim to make the wire rod of double wire. The number of double tracks can be increased or decreased depending on the number of turns of the support punches 22 and 23.

On the other hand, in the above case, the double-wired portion is limited to the barbed portion for each terminal, but the necessary coil or all the coils may be formed by the double-wire winding.

That is, the distance between the two support punches 22 and 23 shown in FIG. 2 is widened to have a length necessary for winding the coil.
The wire rod is wound several times between 22 and 23 to form a double wire having a predetermined length, and this double wire is wound in the same manner as above.

As mentioned above, if a double wire is used, not only wire materials of the same diameter,
The windings of the coils having different wire diameters can be continuously wound by the same winding machine.

As described above, the double-wired wire is wound around it and is convenient to handle.

In addition, in the present embodiment, the present invention was carried out for three coils of secondary, tertiary and quaternary coils (N ₂ , N ₃ , N ₄ ) connected to the common terminal, but the number of coils is not limited to this number. However, the present invention can be applied to a transformer having a large number of coils by the same method as in the present embodiment, and can also be applied to an electric winding component having a common terminal in the middle of the inductance coil.

[Advantages of the Invention] As described above, according to the present invention, the winding machine temporarily stops the winding when one coil is formed, but the winding end portion is twisted or hooked to the common terminal. Since the winding is started immediately and the other coil is formed without cutting the wire after being locked, the coil end processing time by the winding machine becomes very fast.

As a result, it is possible to increase the production efficiency of the electric winding component having the common terminal and to provide the electric winding component which can be expected to reduce the cost.
