[Industrial applications]

  The present invention is a computer word processor based on a television and a CRT system. The present invention relates to a deflection yoke used for a display such as.

[0002]

[Prior art]

  In recent years, computer CRT displays and televisions have high performance and high resolution. High-performance deflection yoke used for this display and television Is being developed.

[0003]   The conventional deflection yoke will be described below. FIG. 4 is a vertical cross section of a conventional deflection yoke. It is a figure. 1 is a horizontal coil, 2 is a horizontal coil insulation frame, 3 is a core for a vertical deflection coil Reference numeral 4 denotes a ridge formed on the outside of the side wall of the horizontal coil insulating frame.

[0004]   The operation of the deflection yoke configured as described above will be described below. . The ridge portion 4 is in contact with the vertical deflection coil core 3 arranged further outside thereof. And a gap is formed between the vertical deflection coil core 3 and the horizontal coil insulating frame 2, Moreover, the position of the vertical deflection coil core 3 is regulated.

[0005]

[Problems to be solved by the device]

  However, in the above-described conventional configuration, the ridge portion contacts the surface of the vertical deflection coil core. The vertical deflection coil core is moved up and down, tilted and left. It is difficult to adjust to the shift to the right, and it is difficult to maintain convergence and optimum yoke position. It is difficult, and neck shadows and distortions occur, and the image on the CRT display is bad. It had a problem of affecting.

[0006]   The present invention solves the above-mentioned problems of the prior art by focusing on the convergence and optimum yoke. Secures the position and causes shadows on the image of CRT displays such as neck shadows and distortion. An object of the present invention is to provide a deflection yoke that suppresses the generation of various factors that affect the sound. .

[0007]

[Means for Solving the Problems]

  In order to achieve this object, the deflection yoke according to claim 1 of the present invention is a horizontal coil. And a protrusion formed on the outer side wall of the insulating frame or on the inner side wall of the vertical deflection coil core. , Formed inside the vertical deflection coil core side wall or outside the horizontal coil insulation frame side wall And a locking portion that locks the protrusion. The deflection yoke according to claim 2 is the outer wall of the small-diameter portion of the horizontal coil insulating frame, Is erected on either side wall of the inner wall of the small diameter part of the vertical deflection coil core, and A protrusion formed so as to abut the side wall on one side, the tip of the protrusion being formed. It has a structure in which a flexible elastic portion is formed.

[0008]   Here, the ridges are parallel or orthogonal to the large-diameter portion of the horizontal coil insulation frame, or are inclined. It is formed so as to be obliquely provided over the entire circumference or a part of the side wall at equal intervals. In addition, the ridge The parts may be formed not only in the radial direction of the horizontal coil insulating frame but also in the vertical direction. Mating The locking part, which consists of recesses and locking projections, projects the vertical deflection coil core at the optimum position. It is formed so as to be engaged with or locked to the starting portion. The depth of the recess and the The height is 1 to several mm, and the depth and height of the vertical deflection coil core are easy to mount. It The protrusions are formed in the shape of ribs or protrusions by dividing the entire circumference of the small diameter portion or dividing it at equal intervals. Be done. When forming the elastic part on the horizontal coil insulation frame, make sure that it is bent downward. When forming the core for the vertical deflection coil, bend it upward to form a deflection It is preferable in terms of workability that the protrusion does not become an obstacle during assembly of the yoke.

[0009]

[Action]

  With this configuration, the ridges formed on either side wall and the side wall on the other side are formed. By fitting or locking the recessed part or the locking part for fitting, or a small diameter Since the protruding part that has the elastic part at the tip of the part presses while having the elasticity of one side wall It is possible to regulate the movement of the vertical deflection coil core up and down, tilt, and left and right. Yes, maintaining convergence, optimum yoke position, neck shadow, distortion, etc. Can be prevented, and the best image can be formed on a CRT display or the like.
