Abstract

PURPOSE:To improve positioning accuracy when a horizontal coil bobbin is inserted into an integrated core around which vertically deflecting coil is wound by directly connecting the protrusion provided on the horizontal coil bobbin to the inner surface of the integrated core. CONSTITUTION:Four protrusions 10 are provided on the bell-shape taper part 1a of a horizontal coil bobbin 1. When an integrated core 5 around which a vertically deflecting coil is wound into a saddle form is fitted to the bobbin 1, the front end of each protrusion 10 is brought into contact with the inner surface of the core 5, which is held therewith accurately, by providing the protrusion 10 on the outer surface of the bobbin 1. When a small protrusion is provided on the front end of each protrusion 10, and when the core is to be inserted, since the core is pressed in while the small protrusion is abrased, even when the inner diameter of the core 5 is uneven, this unevenness can be absorbed, and the core 5 is held more accurately and more easily. A spacer made of rubber is not needed, and the positioning accuracy when the bobbin 1 is inserted into the core 5 can thus be improved.

になるという長所がある。The method of assembling such a conventional deflection yoke is as follows. First, the vertical deflection coil 6 has a saddle shape that creates a desired magnetic field distribution on the inner surface of the magnetic core 9 while hooking the enamel wire on the large-diameter end side hook 7 and the small-diameter end side hook 8 of the integrated core 5 in order. Wound to form. On the other hand, the horizontal deflection coil 2 hooks the enamel wire on the large-diameter end side hook 3 and the small-diameter end side vertical groove 4 of the horizontal coil bobbin 1 in order, similarly to the vertical deflection coil 6.
The inner surface is wound so as to form a saddle shape that produces the desired magnetic field distribution. When the winding is completed, the horizontal coil bobbin 1 is fixed in one direction by inserting the horizontal deflection bobbin 1 in one direction from the large diameter end side of the integrated core 5 wound with the vertical deflection coil 6 to the small diameter end side. Complete. As described above, the use of the integral bobbin 1 and the integral core 5 has the advantages that the number of parts is smaller than in the case of the divided bobbin and the core, and the unidirectional assembly is possible and the assembly is easy.

う問題点があった。As described above, in the conventional deflection yoke, the horizontal coil bobbin 1 is inserted in one direction from the large diameter end portion side of the integrated core 5 to the small diameter end portion side, and at that time, the horizontal coil bobbin 1 is inserted. Since a rubber spacer is used for positioning between the core coil 5 and the integrated core 5, the thickness of the rubber spacer is difficult to control and the manufacturing variation is large. However, there is a problem in that the accuracy of positioning with respect to each other becomes low, and convergence on the screen is likely to occur, and it takes a lot of time to adjust convergence in a subsequent process.
