Abstract

PURPOSE:To prevent the occurrence of current leak due to the direct action of mechanical stress on a soldered section, and improve reliability by clamping and soldering a vertical coil pin and a horizontal coil to a terminal block fixture on a terminal block. CONSTITUTION:A terminal block fixture 11 is constituted in such a way that a material applied with brass nickel plating and solder plating is bent into V-shape, and a slit is formed on the bottom of the V shape. Then, the horizontal coil 7 and the vertical coil pin 4 of a deflection yoke are inserted in the slit of the fixture 11 secured to a terminal block 12, and soldered in a condition where the coil 7 and pin 4 are held under the clamping force of the fixture 11. In this case, solder is deposited on the bottom of the V-shape section of the fixture 11 and a solder amount can be increased. In addition, the soldered section becomes free from direct mechanical stress. Thus, the danger of current leak due to the occurrence of a crack can be eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke having a terminal plate provided with connector pins effective for assembling a television receiver (hereinafter referred to as TV) set.

[0002]

2. Description of the Related Art In recent years, in the deflection yoke, a coupler lead has been mainly used in consideration of rationalization at the time of assembling a TV set.

A conventional deflection yoke of this type will be described with reference to FIGS. As shown in the figure, in the vertical coil 21, a copper wire is wound around a ferrite core 22, and the winding start and the winding end of the copper wire are fixed to a vertical coil pin 24 provided in a pin guide 23 attached to the ferrite core 22,
In the horizontal coil 25, a copper wire is wound around the insulating frame 26, and the start and end of the winding are fixed to the horizontal coil pin 27 attached to the insulating frame 26.

The vertical coil 21 is fixed on the horizontal coil 25 by a cover A28, and the insulating frame 2
As shown in FIG. 5, a terminal plate 32 having a board body 29, a plurality of connector pins 30, and a plurality of terminal plate fittings 31 is provided on the plate 6.
Are attached with the terminal plate fitting 31 and the connector pin 30 connected to each other.

The horizontal coil 27 and the vertical coil pins 24 are soldered to the terminal plate fitting 31 of the terminal plate 32 by soldering.
The connection was made by soldering with No. 3, and then the insulating frame 26 was attached to the cover B34 to form a deflection yoke.

In the above structure, when electric power is supplied to the connector pin 30, the connector pin 30 causes the terminal plate metal fitting 31.
After that, a current flows through the horizontal coil pin 27, the vertical coil pin 24, the horizontal coil 25, and the vertical coil 21 to generate a magnetic field in the horizontal and vertical directions.

[0007]

In such a conventional deflection yoke structure, the connection of the horizontal coil pin 27 and the vertical coil pin 24 to the terminal plate fitting 31 is held by the holding force of the solder 33 alone, and Since the terminal plate fitting 31 is in contact with the horizontal coil pin 27 and the vertical coil pin 24 from only one side, the solder easily flows down during the automatic solder dipping, and the amount of the solder 33 soldered is small.

Therefore, when a large vibration or impact is applied to the deflection yoke, mechanical stress causes cracks in the soldering portions of the horizontal coil pins 27 and the vertical coil pins 24 with respect to the terminal plate fitting 31 to cause current leakage. There was a problem with danger.

In Japanese Utility Model Laid-Open No. 61-139560, terminals for vertical and horizontal coils are wound around terminals provided on a terminal plate and then soldered for connection, and connection is made without relying only on the holding force of solder. A configuration is shown that strengthens the.

However, in such a structure, the lead wires for the vertical and horizontal coils must be wound around the terminals, which is not suitable for automation, and the outflow of solder from the soldering portion is not taken into consideration. It was

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a deflection yoke having a highly reliable adhesion of a soldering portion to be soldered to a terminal plate fitting of a terminal plate.

[0012]

In order to achieve the above object, the present invention provides a vertical coil provided with a vertical coil pin, a horizontal coil provided with a horizontal coil pin, and a terminal provided with a terminal plate fitting connected to a connector pin. A plate is provided, and the terminal plate fitting is soldered by sandwiching the vertical coil pin or the horizontal coil pin.

[0013]

According to the present invention, the vertical coil pin and the horizontal coil pin are sandwiched between the terminal plate fittings and held by the above-mentioned structure,
After that, since the vertical coil pins and the horizontal coil pins are soldered to the terminal plate fittings, they can be connected in a firmly held state and adapted to automation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. As shown in the figure, in the vertical coil 1, a copper wire is wound around a ferrite core 2, and the winding start and the winding end of the copper wire are fixed to a vertical coil pin 4 provided in a pin guide 3 attached to the ferrite core 2, and a horizontal coil 5
Winding a copper wire around the insulating frame 6, and fixing the winding start and winding end to the horizontal coil pin 7 attached to the insulating frame 6.

The vertical coil 1 is fixed on the horizontal coil 5 by a cover A8, and on the insulating frame 6, as shown in FIG. 2, a substrate body 9, a plurality of connector pins 10 and a plurality of terminal plates are provided. The terminal plate 12 provided with the metal fitting 11 is attached in a state where the terminal plate metal fitting 11 and the connector pin 10 are connected to each other.

Further, the terminal plate fitting 11 is made by bending a material plated with brass nickel and solder into a substantially V shape, and a slit 13 for holding the vertical coil pin 4 or the horizontal coil pin 7 is formed in the valley bottom portion. A pair of tongue pieces 14 are provided, and a cut-and-raised piece 15 for attaching to the substrate body 9 is provided.

Then, the horizontal coil pin 7 and the vertical coil pin 4 are inserted into the slits 13 formed in the terminal plate fitting 11 attached to the substrate body 9 forming the terminal plate 12 as shown in FIG. After being held by the sandwiching terminal plate metal fitting 11 by the clamping force, the solder 16 is attached to the terminal plate metal fitting 1
Soldering is performed in a state where a solder pool is formed on the valley bottom portion of 1 and the insulating frame 6 is attached to the cover B17 to form a deflection yoke.

As described above, according to the deflection yoke of the embodiment of the present invention, the terminal plate fitting 11 holds the horizontal coil pin 7 and the vertical coil pin 4, so that the terminal plate fitting 11 holds the horizontal coil pin 7 and the vertical coil pin 4. Therefore, it is possible to prevent the stress from being directly applied to the solder 16.

Further, since a solder pool is formed in the V-shaped valley bottom portion of the terminal plate fitting 11, the amount of solder can be increased.

[0020]

As is apparent from the above embodiments, according to the present invention, the terminal plate fittings provided on the terminal plate are configured to sandwich the vertical coil pins or the horizontal coil pins for soldering. Soldered and fixed in the state of being sandwiched between terminal plate fittings, the mechanical stress is not applied directly to the soldered part, cracks occur, and the risk of current leakage is prevented. You can provide a yoke.
