In FIG. 6, reference numeral 4 denotes an electric wire. FIG. 7 is a view in the same direction as FIG. 6 after the electric wire 4 is wound.

Regarding the conventional winding frame configured as described above, a method of winding the electric wire 4 will be described below.

The electric wire 4 is, for example, an electric wire guide wall 3e → 3d shown in FIG.
→ 3c → 3b → 3a in the order specified number of turns (for example, 14
For a deflection coil for an inch cathode ray tube, 8 turns → 10
Winding → 14 winding → 14 winding → 18 winding). At this time,
For example, when winding around the electric wire guide wall 3c, as shown in FIG. 5, the electric wire 4 is hooked on the electric wire guide claw 2c in the direction of the arrow shown in the figure, and inserted into the electric wire guide wall 3c.

Problems to be Solved by the Invention However, as shown in FIG. 7, in the vicinity of the final winding portion having the specified number of turns (for example, in the case of the wire guide wall 3d, the number of turns is 8 since the specified number is 10 turns). In addition, the electric wire 4 is not uniform in the electric wire guide wall 3, and the electric wire 4 is distorted in the electric wire introduction direction. Also, conventionally, in order to solve the above-mentioned phenomenon, the space between a certain winding guide claw 2 and an adjacent wire guide claw 2 has been devised so as to be shortened. Due to the thickness of the introduction nozzle, it was impossible.

The present invention has been made in view of such a problem,
It is an object of the present invention to allow wires to be evenly distributed within a wire guide wall after a specified number of turns and to be wound so as to eliminate stacking and offset of the wires.

Means for Solving the Problems In order to achieve the above object, the present invention has an electric wire guide wall bent and formed on an inner surface extending from one end to the other end of the winding frame to form a coil in an intended shape, An electric wire is wound around a portion of the winding frame between the electric wire guide walls, and winding guide claws for introducing the electric wire between the electric wire guide walls are formed at both ends of the winding frame. The winding guide claw is such that the tip of the winding guide claw is located at an intermediate position between the ends of the wire guide walls, and the tip of the wire guide wall and the tip of the winding guide claw are on the same line in the circumferential direction of the winding frame. The end of the wire guide wall in the vicinity of the winding guide claw is formed so as to be inclined so that the height from the winding frame gradually changes.

Operation According to such a configuration, the electric wire is wound around the winding frame portion between the wire guide walls formed by bending the inner surface from one end to the other end of the winding frame, so that the wire is adjusted to the winding distribution. Uniform winding is possible, and the tip of the wire guide wall and the tip of the winding guide claw are arranged on the same line in the circumferential direction of the winding frame, and the winding guide claw is located at an intermediate position between the tips of the wire guide walls. Because the tip of is located
The winding guide pawl divides the electric wire in the electric wire guide wall into two parts, so that stable winding can be performed without dislodging or offsetting of the electric wire, and the leading end of the electric wire guide wall and the leading end of the winding guide pawl. Are arranged on the same line in the circumferential direction of the winding frame, uniform winding is possible over the entire length of the wire guide wall, and furthermore, the end of the wire guide wall in the vicinity of the winding guide claw is separated from the winding frame. Is formed so that the height of the wire gradually changes, the wire is smoothly bent, the wire is not damaged, and disconnection and insulation failure can be prevented.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows one of the winding frames 1 according to the present invention. 2
Is a winding guide claw, and 3 is an electric wire guide wall. Here, the tip of the winding guide claw 2 is located at an intermediate position between the tips of the wire guide walls 3, and the tip of the wire guide wall 3 and the tip of the winding guide claw 2 are the same in the circumferential direction in the winding frame 1. It is configured to be arranged on a line. Specifically, the tip of the winding guide claw 2b is located at an intermediate position between the tip of the wire guide wall 3a and the tip of the wire guide wall 3b, and is located between the tip of the wire guide wall 3b and the tip of the wire guide wall 3c. The tip of the winding guide claw 2c is located at the position
The tip of the winding guide claw 2d is located at an intermediate position between the tip of 3c and the tip of the wire guide wall 3d. As shown in the figure, the ends of the wire guide walls 3a, 3b, 3c, 3d and the ends of the winding guide claws 2a, 2b, 2c, 2d are arranged on the same line in the circumferential direction of the winding frame 1. ing.

FIG. 2 is a front view showing the vicinity of the electric wire guide walls 3a and 3b in order to explain the deflection coil of the present invention in detail.

As is clear from FIG. 2, the electric wire 4 wound around the gap between the electric wire guide walls 3a and 3b is divided into two groups by the winding guide claws 2b. That is, for example, the wire guide walls 3a and 3b
If the wire 4 is wound 10 times in the gap between
Until the winding is wound between the winding guide claws 2b and 2c,
Six to ten turns are wound between the winding guide claws 2b and 2a.

With the above-described configuration of the deflection coil of the present embodiment, all the electric wires 4 housed in the two electric wire guide walls 3 as in the conventional deflection coil can be connected to the respective electric wire guide walls 3.
Instead of being wound through only one of the winding guide claws 2 (on the wire introduction direction side) provided on an extension of the above, the wire is divided into two winding guide claws 2 and wound. The electric wire 4 is
After passing through the winding guide claws 2 at both ends of the winding frame 1 and guided to the wire guide wall 3, the tip of the winding guide claw 2 is located at an intermediate position between the ends of the wire guide walls 3 and the wire guide Since the end of the wall 3 and the end of the winding guide claw 2 are arranged on the same line in the circumferential direction of the winding frame 1, stable winding can be achieved without dislocation or deviation of the electric wire 4. It is possible, and electric wire 4
Are wound in a state of being uniformly distributed over the entire length of the wire guide wall 3 in the adjacent wire guide wall 3.

Advantageous Effects of the Invention As is apparent from the above description, the deflection coil of the present invention has a configuration in which the tip of the wire guide wall and the tip of the winding guide claw are arranged on the same line in the circumferential direction of the winding frame, and Since the tip of the winding guide claw is located at an intermediate position between the tips of the wires, stable winding is possible without losing or misaligning the wire, and the wire is bent to the inner surface from one end to the other end of the winding frame. Since the wire is wound around the portion of the winding frame between the formed wire guide walls, and the tip of the wire guide wall and the tip of the winding guide claw are arranged on the same line in the circumferential direction of the winding frame. In addition to being capable of uniform winding over the entire length of the wire guide wall, the shape of the coil can be regulated over the inner surface of the winding frame, and uniform winding according to the winding distribution is possible. Since the end of the wire guide wall in the vicinity of the guide claw is formed in an inclined shape in which the height from the winding frame gradually changes, the wire is smoothly bent, the wire is not damaged, and there is no breakage. Insulation failure can be prevented.
