Description

[Detailed Description of the Invention] This invention relates to a coil end processing structure in a winding frame device to which the coil is mounted.

It is desired that the terminal processing of the coil be done easily, and for this purpose conventionally, for example,
As shown in Publication No. 041, a terminal processing structure is provided in which a dovetail groove is formed on the inner surface and periphery of the collar body at the end of the winding, and an insulating plate for insertion of the coil lead wire and pressure welding to prevent removal is firmly fitted into this groove. was provided.

However, in this case, the coil lead wire rises from the bottom of the opening on the inner side of the dovetail groove, rises between the back surface of the dovetail groove and the insulating plate, and is drawn out to the end face of the collar body, so that the coil lead wire is drawn out to the end face of the collar body. When it is firmly fitted, the rising part along the insulating plate is handled by the insulating plate, which has the disadvantage of causing the thin coil lead wire to break, and it is an inconvenience that sufficient care must be taken when fitting the insulating plate. was there.

Further, since the coil lead wire is drawn out to the end face of the collar body, there are many chances for the wire to be damaged externally, which may cause the wire to break.

Furthermore, conventionally, including the above-mentioned terminal processing structure, the winding start terminal and winding end terminal of the coil are individually processed.
Therefore, there was a drawback that the number of processing steps and required parts were large.

This idea was devised based on the above-mentioned circumstances, and its purpose is to easily process the terminals of the coil with a minimum number of parts and man-hours, and to prevent disconnection at the terminals of the coil. It is an object of the present invention to provide a winding frame device as described above.

This invention will be described below with reference to an embodiment shown in FIGS. 1 and 2.

The winding frame device according to this invention is composed of a winding frame 1 and a locking plate 2. The winding frame 1 is formed by, for example, a rectangular cylindrical winding drum 3 with flanges 4 provided at both ends, and these are made of synthetic material. It is integrally molded from an insulating material such as resin.

A coil A formed by winding an electric circuit winding is mounted on the outer periphery of the winding drum 3 and its position is regulated by a flange 4.

At least one of the flanges 4, 4 (in this embodiment, both flanges 4, 4) is provided with a slit-shaped locking hole 5, respectively.

The locking hole 5 has a substantially triangular shape, for example, and has one side open to the end face of the flange portion 4, and a top portion B thereof reaches the outer peripheral edge of the winding drum 3.

Furthermore, the flanges 4, 4 have a plurality of grooves, for example, a pair of grooves 6, 7.
It intersects with the locking hole 5 for a formal appearance.

The lengths C and D of these cut grooves 6.7 are different, and the longer cut groove 6 is provided so that the bottom of the groove substantially coincides with the top B of the locking hole 5. , the other short cut groove 7
is provided so that the bottom of the groove substantially coincides with the outer periphery of the coil A.

The long cut groove 6 is used to pull out the winding start end E of the coil A so as to pass through the collar 4, and the short cut groove 7 is used to pull out the winding end end F of the coil A from the collar. It is used for drawing out the hole through the hole 4.

The locking plate 2 is made of a material such as a synthetic resin and has the same shape as the locking hole 5, so in this embodiment it is approximately triangular. This clamps the coil winding start end E between the insertion tip 2a and the bottom of the cut groove 6, and also holds the coil winding start end E between the insertion tip 2a and the bottom of the cut groove 7. The terminal portion F at the end of the coil winding is held between them.

In addition, 8 in the figure is a cylindrical part having a partition 9 integrally provided on the outer surface of the collar part 4, although it is not necessarily required.
The connecting portions between the drawn-out coil terminal portions E and F and the lead wire 10 are housed in the inner spaces 8 a and 8 b.

Therefore, in order to attach the coil A to the winding drum 3 of this winding frame device, one of the flanges 4 is arbitrarily selected, and the winding start end part E is passed through the long notch 6 of the collar part 4. The winding wire is wound while being held in place, and after completing the predetermined winding operation, the end portion F of the winding end is passed through the short notch groove 7 adjacent to the notch portion 6, and the coil A is attached.

Thereafter, processing of these coil end portions E and F is completed by simply pressing and inserting the locking plate 2 into the locking hole 5.

As a result, the coil end portions E and F are held substantially simultaneously between the bottoms of the pair of long and short notch grooves 6 and 7 and the insertion tip portion 2a or one side 2b of the locking plate 2, respectively.

In this way, the terminal processing can be easily performed with one touch, and since the coil terminal parts E and F can be processed simultaneously, only one locking plate 2 is required and the work can be done only once.

Further, since the coil terminal parts E and F are drawn out so as to pass through the flange part 4 and are not wired to the end face of the flange part 4, there is no chance of external damage and disconnection.

Furthermore, the coil end portions E and F are connected to the cut grooves 6 and 7 and the locking plate 2.
Since the coil terminals E and F are not handled when the locking plate 2 is press-fitted into the locking hole 5, the locking plate 2 can be inserted and installed very easily. At the same time, the coil terminal portions E and F will not be disconnected.

Note that this invention is not limited to the one embodiment described above, and can be implemented in various modifications.

For example, as shown in FIG. 3, an intermediate cut groove 11 of an intermediate length is formed between the cut groove 6 for drawing out the end portion at the beginning of winding and the cut groove 7 for drawing out the end portion at the end of winding. If provided, it is possible to simultaneously perform terminal processing of the intermediate draw-out terminal portion of the coil with the intermediate tap.

Further, the plurality of cut grooves may have different lengths if necessary, and the position of the tip (groove bottom) thereof is not limited to that in the above embodiment.

Furthermore, the shapes of the locking plate 2 and the locking hole are not limited to triangular shapes, but may be of any shape.

Since this invention is as explained above, all the terminal processing of the coil can be done at the same time with a one-touch operation by simply inserting the locking plate into the locking hole, so it is easy with a minimum number of parts and man-hours. It can be terminal-treated and is suitable for large quantities of charcoal, and its practical effects are extremely large.

In addition, since the coil terminal part is not wired to the end face of the flange, there is no disconnection due to external damage, and since it is not handled when inserting the locking plate, there is no disconnection and the insertion of the locking plate is easier. There are other effects.
