Abstract

PURPOSE:To prevent the short circuit by the contact between the drawing lead of a vertical coil and the copper wire of the vertical coil in a deflection yoke used for a cathode-ray tube. CONSTITUTION:A lead 5 for connecting upper and lower coils to each other is drawn around in a gap between the recessed part in the core 3 outer circumferential surface center part of a vertical coil 4 and the copper wire of the vertical coil 4 to prevent the short circuit by the contact between the lead 5 and the copper wire of the vertical coil 4, and a machine for drawing work of the vertical coil 4 can be omitted in the production line.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke used in cathode ray tubes such as television receivers.

0002

2. Description of the Related Art In recent years, deflection yokes of this type have been produced in large quantities on automated lines.

A conventional deflection yoke will be explained below with reference to FIG. In the figure, the winding has a horizontal coil 2 wound in a saddle shape around an insulating frame 1, and a vertical coil 4 wound around a core 3 in a toroidal shape. wire or another lead wire 7,
It is designed to be connected to the terminal board 6.

0004

[Problems to be Solved by the Invention] However, in the above configuration, since the lead wire 7 of the vertical coil 4 runs along the outside of the vertical coil 4, it comes into contact with the copper wire of the vertical coil 4, and is not under pressure. Since this may cause a short circuit, the lead wire 7 is either sufficiently slackened or a guide is provided for the lead wire 7. In addition, when assembling an automated machine line, vertical coil 4
There is a problem in that a machine for the routing work must be installed inside the line.

SUMMARY OF THE INVENTION The present invention solves the above problems, and aims to provide a deflection yoke that prevents short circuits caused by contact between the lead wire of the vertical coil and the copper wire of the vertical coil.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention connects the upper and lower coils to the gap between the vertical coil copper wire and the recess in the center of the outer peripheral surface of the core of the vertical coil before winding the vertical coil. It is made by routing lead wires.

[0007]

[Function] In the above-described configuration, the present invention has the lead wire of the vertical coil located in the gap between the recess in the center of the outer peripheral surface of the core and the copper wire of the vertical coil, so that short-circuiting between the lead wire and the copper wire of the vertical coil is prevented. Prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the deflection coil of the present invention will be described below with reference to FIGS. 1 to 4. Note that the same numbers are used for the same constituent members as those explained in the conventional example.

As shown in the figure, the difference from the conventional example is that the lead wire 5 of the vertical coil 4 is routed in advance along the recess in the center of the outer peripheral surface of the core 3 and connected before winding the vertical coil 4. It's about keeping it. Therefore, there is no contact between the copper wire of the wound vertical coil 4 and the lead wire 5, and a machine for drawing the vertical coil can be omitted from the automated line.

0010

As is clear from the description of the embodiments above, the deflection yoke of the present invention has a lead wire for connecting the upper and lower coils before winding the vertical coil in the gap between the core of the vertical coil and the vertical coil copper wire. By routing the vertical coil, it is possible to prevent contact with the wound copper wire, and when setting up a machine-based automated line, it is possible to omit the machine for the vertical coil routing work from the line.
