た。2. Description of the Related Art FIG. 9 shows a deflection yoke mounted on a television receiver or a display device. In this type of deflection yoke, a horizontal deflection coil is attached along the inner peripheral surface of a bobbin 2 having a bosh-like shape, and a vertical deflection coil and a core are attached outside the bobbin. The deflection coil of this deflection yoke has been formed by a method of winding a single conductor wire as a single core wire into a predetermined shape using a die or a bobbin. However, according to this method, there is a problem that the winding distribution varies, and it is difficult to wind according to the design instruction. On the other hand, recently, the size of television receivers has become larger and high-definition televisions have advanced. Also, with the advent of high-definition display devices, etc., there is a standard such as color shift of the screen of the cathode ray tube of these devices, that is, convergence etc. It is becoming more and more severe, and accordingly, more precise control of the deflection magnetic field is desired. Therefore,
In the conventional method of winding a single conductor wire to form a deflection coil, it is difficult to wind the wire according to the design instruction, and a new problem arises in that the above requirements cannot be met.

Since the multi-core parallel conductive wire 15 is used and the multi-core parallel conductive wire 15 is wound around the coil winding groove 5 in a laminated manner, a large displacement of the conductive wire 8 can be eliminated. The production of deflection coils can be expected.

問題があった。As described above, winding a multi-core parallel conductor 15 around the saddle-shaped bobbin 2 to fabricate a deflection coil requires complicated winding work, and particularly, the crossover portions on the head side and the neck side are complicated. Since the winding operation is complicated to control the winding operation and it takes a long time, the work efficiency is poor and the productivity of the deflection coil is low.

When the multifilamentary parallel conductor 15 is wound from the crossover portions 12 and 13 to the coil winding groove 5 of the coil distribution portion 14, the multifilar parallel conductor 15 is not wound along the coil winding groove 5 while adjusting the guide 17. As a result, the multifilamentary parallel conductor 15 is difficult to fit in the coil winding groove 5 and has a problem of being twisted. Further, as shown in FIG. 6B, the corners 16 of the crossover portions 12 and 13 are connected to the cathode ray tube side.

【００３１】さらに、提案例のような高価な専用の巻線
機を用いる必要がなく、安価な従来のフライヤー方式の
巻線機で巻けるので、鞍型の偏向コイルを安価に形成す
ることができる。Furthermore, since it is not necessary to use an expensive dedicated winding machine as in the proposed example and the winding can be performed by an inexpensive conventional flyer winding machine, a saddle type deflection coil can be formed at a low cost. .
