Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deflection yoke disposed in a cathode ray tube of a television receiver or the like.

Conventional technology FIG. 4 is a side view showing a conventional deflection yoke.

In FIG. 4, 1 is a winding frame, 2 is a trumpet-shaped core attached to the side surface of the winding frame 1, and the core 2 is made of an oxide magnetic material such as ferrite.

3 is a winding wound around the core 2, and the winding 3 is divided into a coil portion 3a and lead-out portions 3b and 3c. The coil portion 3a and the core 2 constitute a vertical deflection coil.

4.5 is a winding frame attached to the front end and rear end of the core 2, respectively, and the winding frame 4 is provided with a plurality of ribs 4a, and the coil portion 3a is held between each rib 4a. ing. 6 is provided on the winding frame 1, and has a plurality of terminals 6a, 6b.
, 6c, 6d, and 6e, the lead-out portions 3b and 3c of the winding 3 on the side shown in the terminal plate 6 are terminals 6a.
, 6b, respectively. Further, lead-out portions 3d and 3e of the windings on the opposite side (not shown) are soldered to the terminals 6C26b, respectively. Also, the drawer part 3b.

The base portion and middle portion of 3c are adhered to the coil portion 3a with an adhesive. The lead-out portions 3d and 3e are similarly bonded to the coil portion of the winding on the opposite side.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, in order to fix the base part of the drawer part so that it does not move, and to fix the middle part of the drawer part to the coil part so that the drawer part does not wobble, adhesive is used. Because adhesive was used, productivity was poor because it was impossible to move on to the next process until the adhesive hardened and the pull-out part was fixed to the coil part.

The present invention solves the above-mentioned conventional problems, and aims to provide a deflection yoke that can fix the drawer portion without using adhesive and improve productivity.

Means for solving the problem In order to achieve this objective, multiple ribs were provided protruding from the winding frame attached to the core, a notch was provided in the rib, and the lead-out part of the winding was held in the notch. It has a structure.

Function: With this configuration, the drawer portion can be fixed without using adhesive.

Embodiment FIGS. 1 and 2 are side views showing a deflection yoke in an embodiment of the present invention. 1 and 2, 1 is a winding frame, 2 is a core, 3 is a winding wire, 3a is a coil portion, 3b,
3c, 3d, 3e are drawer parts, 6 is a terminal board, 6a, 6b,
Terminals 6c, 6d, and 6e are the same as the conventional structure. 8 and 9 are winding frames attached to the front and rear ends of the core 2, respectively, and the winding frame 8 is provided with a plurality of ribs, and the coil portion 3 is provided between each rib. . Some of the plurality of ribs are provided with a notch through which the drawer passes. 8a and 8b are ribs provided with notches 10 and 11, respectively, which open toward the front end of the core 2, and an enlarged side view of the rib 8a is shown in FIG. 8c, 8d
8e and sf are ribs each provided with notches 12 and 13 that opened toward the front end of the core 2; 8e and sf are ribs each provided with notches 14 and 15 that opened toward the front end of the core 2; , 8h are ribs each provided with notches 16 and 17 that open toward the rear end of the core 2.

The wiring of the deflection yoke configured as above will be explained.

First, the wiring of the winding 3 on the illustrated side will be explained. The drawn-out portion 3c is passed through the notch 13, wound around the rib 8d several times, and soldered to the terminal 6a. The drawn portion 3b is passed through the notch 16 and wound around the rib 8g several times. Next, the pull-out portion 3b is brought into contact with the end surface perpendicular to the circumferential direction of the rib 8, and the pull-out portion 3c is passed through the notch 14 and hooked onto the rib 8e. Next, the pull-out portion 3c is brought into contact with the end surface perpendicular to the circumferential direction of the rib 8, and passed through the notch 12 and the notch 10,
Hook it onto the ribs 8c and 8a, and solder it to the terminal 6b.

Next, the wiring of the winding that is not shown will be explained. After the lead-out part 3d is passed through the notch, the wires are wired in the same way as the lead-out part 3c until it is passed through the notch 12. After this rib 8
Hook the drawer portion 3d onto the terminal 6c and solder it to the terminal 6c. Moreover, the drawer part 3e is passed through the notch part 17 and hooked on the rib 8h. Next, the pull-out portion 3e is brought into contact with the end surface perpendicular to the circumferential direction of the rib, and the pull-out portion 3e is passed through the notch 15 and hooked onto the rib 8f. Next, the pull-out portion 3c is brought into contact with the end surface perpendicular to the circumferential direction of the rib, and passed through the notch 13 and the notch 11, and
Hook it onto the ribs 8d and 8b, and solder it to the terminal 6b.

As described above, according to this embodiment, a plurality of ribs are formed on the winding frame 8 attached to the front end of the core 2, a notch is provided in the rib, and the lead-out portion of the winding is held in the notch. This eliminates the need to fix the drawer portion with adhesive, improving workability and productivity.

Effects of the Invention The present invention has a plurality of ribs protruding from the winding frame attached to the core, a notch is provided in the rib, and the lead-out portion of the winding wire is held in the notch, thereby eliminating the need for adhesives. Since the pull-out part can be fixed, there is no need to move on to the next process until the adhesive hardens, which is the case with conventional methods, and productivity is improved because the time can be shortened.
