A saddle-shaped core is installed at the periphery of the bobbin 18. Thus, the winding can be carried out surely and quickly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deflection yoke used in cathode ray tubes such as television receivers and displays.

2. Description of the Related Art A conventional deflection yoke was constructed as shown in FIGS. 6 and 7.

That is, 1 is a core made of saddle-shaped ferrite, etc.;
is a funnel-shaped vertical coil bobbin with outer circumferential winding grooves 3 at both ends, 4 is a vertical coil wound on this vertical coil bobbin 2, and 6 is a funnel-shaped bobbin with outer circumferential winding grooves 6 at both ends. A horizontal coil bobbin 7 is a horizontal coil wound around the horizontal coil bobbin 6.

In the above, the outer diameter dimensions of the respective flanges 8 and 9 forming the outer circumferential winding groove 3 of the vertical coil bobbin 2 and the outer circumferential winding groove 6 of the horizontal coil bobbin 6 were configured to be the same.

Problems to be Solved by the Invention In the conventional configuration described above, as shown in FIG. 7, when winding the vertical coil 4 and the horizontal coil 7 on the respective coil bobbins 2. In addition, the guide nozzle must be reliably swung in order to insert the wire into the outer circumferential winding grooves 3 and 6, which requires a considerable amount of time and effort to wind the wire, resulting in poor productivity.

It is an object of the present invention to provide a deflection yoke that eliminates the above-mentioned conventional drawbacks and allows winding work to be performed reliably and quickly.

Means for Solving the Problems In order to solve the above problem, the present invention comprises a horizontal coil bobbin wound with a horizontal coil, a horizontal coil bobbin wound with a vertical coil v'c, and a saddle-shaped core. The entire outer end face side of the flange, which constitutes the entire outer circumferential winding groove provided at both ends of both coil bobbins, is configured to have a large diameter.

Effect: With the above configuration, the winding work when winding the vertical coil and the horizontal coil on their respective coil bobbins can be performed extremely efficiently.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4 of the drawings.

First, in FIGS. 1 and 2, 12 is a horizontal coil bobbin formed in a funnel shape, and two flanges 13 are provided at each end.
．． 14 forms an outer circumferential winding groove 16, and a plurality of winding grooves 16 are formed on the inner surface of the funnel-shaped portion. Furthermore, the flanges 13 and 14 forming the outer circumferential winding groove 16 are configured such that the flanges 14 on the outer end surface side have a larger outer diameter than the flanges 13 on the inner side.
A horizontal coil 17 is wound around 2.

A vertical coil bobbin 18 similarly formed in a funnel shape is attached to the outer peripheral surface of the horizontal coil bobbin 12. This vertical coil bobbin 18 also has two tsuba 19 on each end.
．． 20 forms an outer circumferential winding groove 21, and a plurality of winding grooves 22 are formed on the inner surface of the funnel-shaped portion. The flanges 19 and 20 forming the outer circumferential winding groove 21 are configured such that the outer diameter of the flanges 2o on the outer end surface side is larger than that of the flanges 19 on the inner side. A vertical coil 23 is wound around this vertical coil bobbin 18 .

A saddle-shaped core 24 is incorporated in the outer circumference of the vertical coil bobbin 17.

With this configuration, the situation when winding a coil around each coil bobbin 12, 18 will be explained with reference to FIGS. 3 and 4. In FIGS. 3 and 4, the horizontal coil bobbin 12
An example of winding the horizontal coil 1A will be explained below.

The conducting wire 26 drawn out from the winding groove 16 of the horizontal coil bobbin 12 is fitted into the outer circumferential winding groove 15, and then fitted into the next winding groove 16 and wound. At this time, among the flanges 13 and 14 that form the outer circumferential winding groove 16, the outer diameter of the outer end side flanges 14 is larger than the inner flanges 13. The conductive wire 26 can be reliably fitted into the wire 16, and the efficiency of the winding work can be significantly improved. In addition, in FIG. 4, the outer diameter of the collar 14 is configured so that the lead-in side of the lead-in wire 26 has a larger diameter than the lead-out side of the lead-in wire 26, so that the lead-in wire 26 can be fitted into the outer circumferential winding groove 16 more reliably. The system is designed to perform the following tasks.

Effects of the Invention As described above, in the deflection yoke of the present invention, the outer diameter of the collar constituting the outer circumferential winding groove of the coil bobbin around which each coil is wound is configured such that the outer end surface side has a larger diameter. The coil winding work can be done extremely efficiently and productivity can be improved, making it a valuable tool in industry.
