Abstract

PROBLEM TO BE SOLVED: To enable a choke coil to be continuously assembled and lessened in positioning cost by a method wherein a winding coil is continuously wound without being cut off into unit winding coils, and the unit winding coils are linked together at a continuous part between the adjacent coils so as to cope with a forward feed process. SOLUTION: A continuous winding coil 10 is composed of unit winding coils 11 which are continuously formed without cutting off a straight angle copper wire 1. At this point, the winding coil 10 can be surely fed without slipping through such a manner that feed holes made in the continuous parts 13 of the winding coils of the straight angle copper wire are engaged with the teeth of a toothed wheel. The continuous winding coil 10 is composed of the unit winding coils 11 arranged in bilateral symmetry about the continuous part 13, whereby cores are assembled to the two lateral unit winding coils 11 at the same time in a forward feed process in the manufacture of a choke coil.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a wound coil and a choke coil used as an electronic device.

[0002]

2. Description of the Related Art Conventionally, in the production of choke coils,
The winding coil which is the component was wound for each winding coil, and was supplied separately. The choke coil composed of the wound coil and the core has a small number of components, but since each wound coil is supplied separately, when assembling the wound coil and the core, the positioning of the wound coil and the core is performed one by one. Had to do.

[0003]

However, in order to perform positioning of the wound coil and the core, positioning equipment for performing the assembly one by one and a long time for positioning are indispensable, which causes an increase in cost. There was a problem.

Accordingly, the present invention eliminates the need for a positioning device for each winding coil and the core when assembling a choke coil, and assembles the choke coil continuously, thereby reducing the cost for positioning. An object of the present invention is to provide a method for manufacturing a wound coil and a choke coil.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a choke coil mainly composed of a rectangular coil made of a rectangular copper wire and a choke coil composed of a core, the coil being wound in parallel with the long side of the cross section of the rectangular copper wire. A winding coil characterized by being able to easily cope with the progressive feeding process by winding the coil continuously without cutting it for each winding coil, and connecting it at a continuous portion between each winding coil. is there. In addition, the wound coil is formed into a choke coil by punching a hole in a continuous portion of a wound coil connecting each wound coil and engaging with a gear, thereby reliably feeding the coil, and inserting and assembling a core into each wound coil. Things. In addition, you may distribute each winding coil left and right with respect to a winding coil continuous part.

That is, the present invention relates to a wound coil for a choke coil, wherein the wound coil is formed by winding a rectangular copper wire in parallel with the long side of its cross section, and cutting the wound coil for each wound coil. This is a continuous winding coil characterized by being formed continuously without being connected to each other and connecting each winding coil by a continuous portion of the winding coil so as to correspond to a progressive feeding step.

[0007] The present invention provides the continuous winding coil,
A continuous winding coil, characterized in that a hole is provided in a continuous portion of the continuous winding coil so that the winding of the winding coil can be reliably performed by meshing with the gear teeth.

[0008] The present invention provides the continuous winding coil,
The continuous winding coil is characterized in that each winding coil is distributed left and right with respect to a continuous portion of the continuous winding coil.

The present invention is a method for manufacturing a choke coil, wherein a core is incorporated into the continuous winding coil and then separated at a continuous portion between the winding coils.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a continuous winding coil according to an embodiment of the present invention, in which each winding coil has a continuous shape. FIG.
In the continuous winding coil 10, the winding coil 11 is continuously produced without cutting the rectangular copper wire 1. At this time, the angle θ between the direction axis X of the continuous portion 13 of the winding coil connecting the winding coil 11 and the direction axis S passing through the winding center 14 of the winding coil and parallel to the foot 12 of the winding coil is arbitrary. is there.

Since the continuous winding coils 10 are arranged at equal intervals, the position of the first winding coil 11 is determined and is sent at a predetermined length, so that positioning of the second and subsequent winding coils is unnecessary. is there.

FIG. 2 shows a continuous winding coil according to another embodiment of the present invention. In FIG. 2, the continuous winding coil 10
The punched hole 15 is formed in the continuous portion 13 of the winding coil 11 of the flat copper wire 1 and meshes with the gear teeth 16 so that the winding coil 11 can be fed without slip.

FIG. 3 shows a continuous winding coil according to another embodiment of the present invention. In FIG. 3, two continuous winding coils 10 are arranged on the left and right winding coils 11 in the sequential feeding process of manufacturing the choke coil by arranging the winding coils 11 alternately on the left and right sides of the continuous portion 13.
At the same time, it is possible to improve the manufacturing capacity by assembling the core.

Next, a method of manufacturing a choke coil will be described. The method for manufacturing a choke coil according to the present invention includes a step of inserting a core one after another in the center of the winding coil 11 of the continuous winding coil 10 according to the above-described embodiment of the present invention, continuously assembling the choke coil, and This is a manufacturing method of obtaining a desired choke coil by cutting and separating at an arbitrary position of the portion 12 or the continuous portion 13 of the wound coil. This manufacturing method has made it possible to reduce costs.

[0016]

As described above, according to the present invention,
When assembling a choke coil, a method for manufacturing a continuously wound coil and a choke coil that eliminates the need for a positioning device for each wound coil and the core, enables continuous assembly of the choke coil, and reduces the cost for positioning the wound coil Can be obtained.
