う問題を解決することを目的としている。[0005] In the conventional deflection yoke as described above, the auxiliary coil and, either the deflection of the horizontal deflection coils and vertical deflection coils that are electrically connected in series with the said auxiliary coil Since the coil and the coil are wound in a winding form different from that of the slot bobbin, it is necessary to attach the auxiliary coil to the slot bobbin and connect it to one of the deflection coils. Furthermore, since the auxiliary coil is simply fitted into the groove of the slot bobbin and fixed to the groove with an adhesive or the like, there is a risk that the auxiliary coil may stick out of the groove and come into contact with the cathode ray tube. Further, when the deflection yoke is attached to the cathode ray tube, the auxiliary coil protrudes from the groove portion, so that the deflection yoke can be attached in a smaller dimension in the cathode ray tube in the tube axis direction. Therefore, it is deflected when the deflection yoke is fully filled on the face plate side, that is, at the foremost position where the deflection yoke is in close contact with the cone portion of the cathode ray tube, and when the deflection yoke is retracted to the neck rear end side from this close contact position. The distance from the position of the deflection yoke when the electron beam hits the inner glass of the cathode ray tube and starts to form a shadow on the face plate (hereinafter, this distance is abbreviated as "neck shadow tolerance") There is a problem in that it is remarkably reduced as compared with a non-deflecting yoke.
Further, since the work of attaching the auxiliary coil to the groove portion and the work of connecting the auxiliary coil and one of the deflection coils are necessary, there is a possibility that a manufacturing error may occur and the quality of the deflection yoke is not stable. The present invention has been made in order to solve the above-mentioned problems, and connects an auxiliary coil for fine adjustment of deflection to at least one of the horizontal deflection coil and the vertical deflection coil. aims at neck shadow tolerance to solve the problem of lowered by solve inefficiency on the work, and the auxiliary coil strikes the cathode ray tube protrudes on the face plate side of the cathode ray tube that.

下するのを防止することが出来る。According to the present invention, the first plate holding the crossover portion on the face plate side of at least one of the horizontal deflection coil and the vertical deflection coil electrically connected in series with the auxiliary coil. The first connecting wire portion of the auxiliary coil is held by sharing the engaging portion, and the second connecting wire portion of the auxiliary coil is attached to the second engaging portion provided on the surface corresponding to the shape of the cathode ray tube. Since the auxiliary coil is wound around the slot bobbin in a fan shape while holding, the winding can be continuously performed without connecting the auxiliary coil and each end of one deflection coil. Furthermore, since the first crossover part and the second crossover part of the auxiliary coil are held by the first locking part and the second locking part, respectively, and do not directly face the cathode ray tube, the auxiliary coil The coil does not hit the cathode ray tube. Therefore, it becomes possible to install the deflection yoke so as to fill up the face plate side of the cathode ray tube, and it is possible to prevent the neck shadow margin from decreasing.
