Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke device provided with a substrate having terminals to which leads such as vinyl electric wires are wound and soldered.

[0002]

2. Description of the Related Art FIG. 3 is a view showing an example of a deflection yoke device. The deflection yoke device includes a horizontal deflection coil 5, a vertical deflection coil 6, a ferrite core 7, an auxiliary coil 8, a resin frame 1 for fixing the deflection coil, and a substrate 3 on which an electric circuit is mounted and fixed to the resin frame 1. Become. FIG. 4 is a view showing a state of the substrate assembly before the deflection yoke is assembled. The lead wire 2 fixed to the substrate 3 is a vinyl electric wire, and the vinyl electric wire includes a core portion 2a and a vinyl covering portion 2b. The board 3 is provided with a hole 3a through which the vinyl electric wire 2 is passed, and a terminal 4 for winding and fixing the vinyl electric wire 2. In general, the diameter of the hole 3a is set to be one to two times the outer diameter of the vinyl covering portion of the vinyl electric wire for the purpose to be described later.

FIG. 5 illustrates the purpose of a conventional hole 3a for passing the lead wire 2 through the substrate 3 of FIG. Usually, FIG.
As shown in the figure, the core portion 2a
In order to prevent the core wire 2a from breaking or deteriorating due to direct stress, the wire is passed through the hole 3a until the vinyl covering portion of the vinyl wire penetrates, wound around the terminal 4, and soldered. By doing so, even when vibration or load is applied, stress is applied to the vinyl coating portion of the hole 3a and is not directly applied to the core wire, so that disconnection and deterioration of the core wire are prevented.

[0004]

As shown in FIG. 5, the conventional method requires a step of passing the lead wire 2 through the hole 3a.
As described above, the hole diameter of the hole 3a is 1 to the outer diameter of the vinyl electric wire.
Since it is composed of two times, the operation of passing through the hole 3a is a step requiring high accuracy, and there is a problem that the man-hour efficiency is low. FIG. 6 is a view for explaining an arrangement in which the holes 3a of FIG. 5 are replaced by linear grooves 3b. As shown in FIG.
Since the lead wire 2 is slid into the linear groove, the man-hour efficiency is better than that of FIG. However, in this case, since there is no mechanical restriction in the direction parallel to the straight groove 3b, the lead wire 2 may move because the mechanical movement is not performed, or the lead wire 2 may be disengaged from the groove 3b.

SUMMARY OF THE INVENTION The present invention makes it possible to easily perform mechanical fixing, which is required separately from electrical connection between a substrate and a lead wire, in a short time without requiring a high-precision work process, and to improve productivity. The purpose is to greatly improve

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a deflection yoke device having a horizontal deflection coil and a vertical deflection coil, and a substrate provided with lead wire terminals. Is provided with at least one notch comprising an arc-shaped hole and a substantially linear groove extending from a part of the arc-shaped hole to an end of the substrate. A lead wire penetrates and the lead wire is fixed to the lead wire terminal (claim 1).

The lead wire includes a core wire and a covering portion covering the core wire, and the outer diameter of the covering portion is larger than the width of the groove portion of the cutout portion, and the outer diameter of the arcuate hole is The outer diameter of the core wire is smaller than the inner diameter and smaller than the width of the groove.

With such a configuration, the present invention provides a deflection yoke device which can easily and semi-fix a lead wire to a substrate in a short time without requiring a high-precision work process. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be specifically described with reference to FIGS.

FIG. 2 is a view showing a main part of the present invention, and shows a board assembled state in which the lead wire 2 is attached through a keyhole-shaped notch 30 provided on the board 3. FIG.
It is an enlarged view of the keyhole-shaped notch part 30 and a vinyl electric wire.
The keyhole-shaped notch 30 includes an arcuate hole 31 and a straight groove 32 reaching the end of the substrate 3.

As shown in FIG. 1, a core portion 2 of a vinyl electric wire is provided.
a is inserted from the end of the groove 32 to the arcuate hole 31 of the keyhole-shaped notch by slide insertion, and then pulled out until the vinyl covering portion 2b of the vinyl electric wire completely protrudes from the arcuate hole 31. Then, the core wire portion 2a is wound around the terminal 4, and finally, an extra lead core wire portion is cut.

The width W of the linear groove 32 of the keyhole-shaped notch
Is configured to be larger than the outer diameter φb of the lead wire core portion 2a and smaller than the outer diameter φa of the lead wire vinyl coating portion 2b, so that the core wire portion 2a can be inserted, but the vinyl coating portion 2b
Cannot be inserted. Also, the arc-shaped hole 3
Lead wire vinyl coating 2b after being pulled out to 1
Is larger than the width W of the linear groove, and therefore does not come off the arc-shaped hole 31. After the lead wires are attached in this manner, they are soldered to the lead wire terminals 4.

A specific example of the notch and the lead wire will be described. 4
