Abstract

PURPOSE:To prevent breakage of a speed modulating coil due to play of a terminal board by disposing a terminal of the speed modulating coil independently of the terminal board. CONSTITUTION:The tip of a lead wire 32 is inserted into a hole 25 formed on a T-shaped terminal 24 disposed sideways of a yoke cover 21, and then, the lead wire 32 is twisted together with a speed modulating coil 30. These wires are wound around a winding portion 24b for fixture, followed by soldering. A portion of the lead wire covered with a lead assembly 31 with a socket is held by a lead wire holding portion 26. Furthermore, a cover 28 is provided for covering the terminal 24.

2. Description of the Related Art The structure of a conventional deflection yoke device is shown in FIG. FIG. 1 shows a deflection yoke device for projection including a velocity modulation coil, and 1 is a yoke cover integrally provided with a velocity modulation coil coil bobbin portion 2. Reference numeral 3 denotes a terminal board attached to one side surface of the yoke cover 1. The terminal board 3 has a horizontal deflection coil connection terminal 4 of the main deflection yoke, a vertical deflection coil connection terminal 5 of the main deflection yoke, and a sub deflection yoke. 1, a horizontal coil connecting terminal 6, a sub-deflection yoke vertical coil connecting terminal 7, and a velocity modulation coil connecting terminal 8 are provided. In the figure, reference numeral 9 is a velocity modulation coil winding.

The deflection yoke device and a circuit board (not shown) are connected to the terminal board 3 by mounting the lead assembly 10 with a socket, the lead assembly 10 with a socket, and the cover 11 for the live parts (each part). Cover the connection part of the terminal).

[0004]

However, in the above-mentioned conventional deflection yoke device, the terminal board 3 is only fitted and fixed on the side surface of the yoke cover 1, so that the speed modulation coil winding 9 and the speed modulation coil are formed. At the connecting portion with the coil connecting terminal 8 (see arrow A in FIG. 5),
There is a possibility that the speed modulation coil winding 9 in which a thin winding is used may be broken due to the looseness of the terminal board 3. In addition, the cover 1 that covers the live part (connection part of each terminal)
Since 1 is large, there is a problem in that the arrangement of other substrates and components is spatially restricted in the television receiver and the display device main body.

[0005]

In order to solve the above problems, the present invention provides a main deflection yoke and a yoke cover which is attached to the rear of the main deflection yoke and has a coil bobbin portion for winding a velocity modulation coil. In the deflection yoke device having the lead wire and the velocity modulation coil, the hole into which the tip of the lead wire is inserted and the lead wire inserted into the hole and the winding of the velocity modulation coil are twisted together. A substantially T-shaped terminal portion having a winding portion around which the winding wire is wound, a lead wire holding portion provided in the vicinity of the terminal portion, and a terminal portion that covers the terminal portion and faces the lead wire holding portion. And a cover having a rib that prevents the lead wire from falling off.

[0006]

With the above-described structure, the lead wire and the winding of the velocity modulation coil are connected at the terminal portion having a substantially T-shape, and the lead wire is fixed at the lead wire holding portion. Furthermore, the cover covers the terminal portion, and the ribs formed on the cover prevent the lead wires from falling off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 is a top view of the deflection yoke device of the present invention, and FIG. 2 is a side view of the deflection yoke device of the present invention. In each drawing, reference numeral 21 denotes a yoke cover attached to the rear of the main deflection yoke 22, and the coil bobbin portion 2 for the velocity modulation coil is provided to the rear of the yoke cover 21.
3 is integrally molded. Further, as shown in FIGS. 1 and 3, a substantially T-shaped terminal portion 24, a lead wire holding portion 26 for holding the lead assembly 31 with a socket, and a cover 28 are held on one side surface of the yoke cover 21. The cover holding portion 27 is formed integrally.

FIG. 4 shows an enlarged state of the terminal portion 24. The root portion of the terminal portion 24 is a winding portion 24a around which the velocity modulation coil winding 30 is wound, and the lead wire 3 of the lead assembly 31 with a socket.
A hole 25 is formed through which the tip of 2 is inserted.

To attach the lead assembly 31 with socket to the terminal portion 24, first, the two lead wires 32 excluding the coating of the tip of the lead assembly 31 with socket are removed.
The tip of each of these is inserted into each of the holes 25. Then, the winding portion 24b of the terminal portion 24 is twisted together with the winding start portion and the winding end portion of the speed modulation coil winding 30, respectively, as shown in FIG.
Wrap around. Then, as shown in FIG. 3, the covered portion of the lead wire is held by the lead wire holding portion 26. Subsequently, the lead wire 32 wound around the winding portion 24b of the terminal portion 24 and the speed modulation coil winding 30 are soldered to be fixed and electrically connected. Further, the cover 28 is attached from the direction of the arrow as shown. A rib 29 is provided on the back surface of the cover 28 so that the lead wire 32 comes into contact with the lead wire holding portion 26 so as not to fall off.

A horizontal coil connection terminal of the main deflection yoke, a vertical coil connection terminal of the main deflection yoke,
The horizontal coil connection terminal of the sub-deflection yoke and the vertical coil connection terminal of the sub-deflection yoke are provided on a terminal board 33 mounted on the other side surface of the yoke cover 21, as shown in FIG. The mounting structure of the terminal board 33 is substantially the same as that of the conventional deflection yoke device shown in FIG.

According to the present invention, the terminal portion of the velocity modulation coil is provided independently of the terminal board to prevent disconnection of the velocity modulation coil winding due to rattling of the terminal board.

[0012]

As described above in detail, according to the present invention, a deflection having a main deflection yoke and a yoke cover attached to the rear of the main deflection yoke and having a coil bobbin portion for winding a velocity modulation coil is provided. In the yoke device, a hole through which the tip of the lead wire is inserted, and the lead wire inserted through the hole and the winding of the velocity modulation coil are twisted together, and the lead wire and the velocity modulation coil are wound. A substantially T-shaped terminal portion having a winding portion around which a wire is wound, a lead wire holding portion provided in the vicinity of the terminal portion, and a lead which covers the terminal portion and faces the lead wire holding portion. Since it has a cover having ribs to prevent the wires from falling off, there is no need to separately provide a terminal board as in the conventional case, and the winding of the speed modulation coil due to rattling of the terminal board There is no disconnection.
