Abstract

PURPOSE:To obtain a core device excellent in machining and the machining time and even at cost by installing a core and a molding, which are detachably mounted at each corner section of the core and to outer circumferences of which stripe grooves for positioning the layer grains of a coil wire wound on the core are formed. CONSTITUTION:A core 14 and a molding 11, which are set up detachably at each corner section of the core 14 and to the outer circumferences of which stripe grooves for positioning the layer grains of a coil wore wound on the core 14 are shaped, are provided. The stripe grooves for positioning the layer grains of the coil wire are formed to the outer circumferences of adjacent two sides in the molding 11, and recessed sections 12 for fitting are shaped to corner sections corresponding to adjacent two sides, to which the stripe grooves are formed. The molding 11 is prepared at every coil wire having different wire diameters, and length size 13 is made longer than the winding size 15 of the core 14. On the other hand, protruding sections 16, to which the recessed sections 12 of the molding 11 are inserted, are shaped at each corner section of the core 14, and the recessed sections 16 of the molding 11 are conformed and fitted to the protruding sections 16 of the core 14 and the length 13 of the molding 11 is cut in conformity with the winding size 15 of the core 14 when the core 14 is used.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coil winding core device that enables coil winding of a transformer or the like to be perfectly aligned or nearly perfectly aligned.

2. Description of the Related Art Conventionally, in order to perfectly align or almost perfectly align the windings of coils such as transformers, windings are placed at each corner of the winding core 2 of the winding frame 1 as shown in Figure 3 (^) (B). A groove 4 is provided for positioning the layers of the coil wire 3 to be wound, and the diameter and feed pitch and gamma pitch of the coil [3 to be wound] are made uniform.

Problems to be Solved by the Invention In such a conventional structure, since precision of the grooves is required, it is difficult to process by electrical discharge machining, etc., and it also takes a lot of machining time, resulting in poor production efficiency. , the cost will also be very high.

In addition, for each coil wire 3 with a different wire diameter, the stacking thickness dimension 5, middle foot dimension 6, and winding width dimension 7 of the winding core 2 shown in FIG. 3(A) change, and the winding core 2 is prepared each time. There was a problem called ε that had to be solved.

The present invention solves these problems and aims to provide a winding core device that is excellent in terms of processing, processing time, and cost.

Means for Solving the Problems In order to solve this problem, the present invention includes a winding core, a layer of coil wire that is detachably attached to each corner of the winding core, and is wound around the core. It is equipped with a molding provided with grooves for positioning the eyes.

Effect With the above configuration, a molded product with grooves for positioning the winding core and the layer of the coil wire is made separately, and when used, the molded product is cut according to the mid-winding dimension of the winding core. This is used by attaching it to each corner of the winding core. Therefore, the winding core can be processed easily and in a short time. In addition, if you make a molded product for each coil wire with a different wire diameter, and if you make the length of the molded product longer from the beginning, you can also create cores with different wire diameters than before. There is no need to prepare one for each coil wire, and even if the winding dimension of the winding core changes in length or shortness, it can be easily accommodated, and it can be used conveniently.

Example An embodiment of the present invention will be described below based on the drawings.

FIG. 1(^)(8) is a perspective view of a molded product provided with grooves for positioning the winding core and the layers of the coil wire in a coil winding core device according to an embodiment of the present invention. In FIG. 1(B), the molded product 11 has grooves 11a for positioning the layers of the coil wire on the outer periphery of two adjacent sides, and a groove 11a for positioning the layers of the coil wire. A recess 12 is formed. Moreover, this molded product 11 is prepared for each coil wire with a different wire diameter, and the length dimension 13 is also the 1st E! I(
It is longer than the mid-winding dimension 15 of the winding core 14 shown in A).

In FIG. 1 (^), a recess 1 of a molded product 11 is provided with grooves for positioning the layers of the coil wire at each corner of the winding core 14.
The molded product 11 is removably attached to the winding core 14.

When using this winding core 14, as shown in FIG. At this time, the middle dimension of the winding core 14 is 1.
5, the length 13 of the molded product 11 is cut and used.

In this way, the molded product 11 provided with grooves for positioning the layers of the coil wire at each corner of the winding core 14 is attached in accordance with the mid-winding dimension 15 of the winding core 14, and the 21st! As shown in I (B), a molded product 11 has a winding frame 17 attached to both end faces of a winding core 14 and a coil wire 18 attached to a corner of the winding core 14.
From the second layer onwards, the wire is wound successively in multiple layers along the grooves between the wires wound on the lower side to complete the winding. Figure 2 (19.20 in ^j is the stacked thickness dimension and middle foot dimension of the winding core 14 when the molded product 11 having grooves for positioning the layers of the coil wire is attached to the winding core 14. .

Effects of the Invention As described above, according to the present invention, by using a molded product provided with grooves for positioning the layers of the coil wire, the winding core can be easily processed and the processing time can be shortened.
Since it is not necessary to prepare a winding core for each coil wire with a different wire diameter or each time the winding weight size of the winding core changes, the number of winding cores can be reduced and a coil winding device that is excellent in terms of cost can be obtained. be able to.
