[0004] A connector assembly 11 shown in FIG. 17 is attached to the substrate 7 on which the terminals 10 are mounted as described above. As shown in FIG. 17, the mounting method is as follows. First, the lead wire 9 'is wrapped around the terminal 10 through the connector lead 9 through the hole 7c formed in the substrate 7. The state in FIG. 17 in which the connector assembly 11 is attached to the substrate 7 is hereinafter referred to as a “substrate assembly”. Next, the substrate 7
Is attached to the separator 1. At this time, the substrate 7 may be carried into the deflection yoke assembling process in a state where the connecting portion between the lead wire 9 'and the terminal 10 is temporarily soldered. Some are carried in a state in which the lead wire 9 'is merely tied. In the process of assembling the substrate 7 to the separator 1, first, the substrate 7 is attached to the separator 1 as described with reference to FIG. Next, as shown in FIG. 15, the lead wire of each coil, which has a necessary length to facilitate the ganging operation, is passed through a groove 7b provided at the end of the substrate 7 in the distal direction of the terminal 10. While pulling slightly, the extra lead wire is cut off from the root to the tip of the terminal 10. Then, the solder bath shown in FIG. 18B having a shape along the arrangement of the terminals 10 mounted on the board 7 is placed in FIG.
As shown in (A), each lead wire and the terminal 10 are soldered by immersing the deflection yoke device from above the solder bath.

[0005]

As shown in FIG. 16, the terminal 10 of the conventional terminal 10 has a substantially cylindrical shape at the portion 10c for leading the lead wire, so that the surface of the terminal is slippery.
As shown in FIG. 9, for example, after the lead wire 9 ′ of the connector wire 9 is wrapped around the terminal 10 and an extra lead wire is cut, the buckled portion of the lead wire 9 ′ tends to return to the original position. The force will cause some loosening.
In the case of a board assembly which is carried into the deflection yoke assembling process in a state where the lead wire 9 'of the connector wire 9 is merely wrapped around the terminal 10 shown in FIG. In some cases, the barbed portion of the lead wire 9 ′ slips out from the tip of the terminal 10 as shown at 20. Further, when a force F ″ for pushing the connector 8 toward the board is applied as shown in FIG. 13 during a boxing operation for transporting the board assembly, for example, the force for pushing the connector wire 9 toward the distal end of the terminal 10. F 'is generated, and the lead wire 9' is
There has been a problem that the barb portion slips out of the tip of the terminal 10 so as to slip. If the board assembly is put into the assembly process of the deflection yoke device with the bulging portion remaining disconnected from the terminal, the lead wire 9 ′ of the connector wire 9 is attached at the time when the board assembly of FIG. In some cases, it is necessary to perform a wasteful operation of fixing the terminal to the terminal 10. FIG.
An example will be described in which the lead wire 4 'of the vertical deflection coil 4 is tied to the terminal 10 shown in FIG. In the deflection yoke assembling operation, the operator moves the vertical deflection coil 4 to the terminal 13 until the lead wire 4 ′ of the vertical deflection coil 4 is tied to the terminal 10 and soldered, for example, when carrying the deflection yoke device. The portion 4a from which the lead wire 4 'is pulled out (hereinafter referred to as a lead wire drawing portion) may be touched, and a force F may be generated such that the kinked portion is displaced toward the distal end of the terminal 10. Depending on the degree of the force F, the barbed portion of the lead wire 4 'slips off from the tip of the terminal 10 as shown in FIG. 21B, and the lead wire 4' is connected to the terminal 10 in the same manner as described above. In some cases, it was necessary to perform a wasteful work of healing.

As described above, the work of tying the lead wire that has fallen out of the terminal 10 to the terminal 10 is performed by a worker in a different stroke from the worker who first ties the lead wire as shown in the drawing. Since most of the work is performed, a troublesome work such as checking the wiring drawing is required for the operator who performs the repair, and there is also a problem that the risk of erroneous wiring is very high depending on the worker. Further, as shown in FIG.
When a relatively thin lead wire such as the lead wire 6 'of the 4P coil 6 is tied to the conventional terminal 10 and an extra length of the lead wire is cut, the kinked portion becomes coil-shaped and the shrinkable terminal 10 In some cases, it was concentrated at the root (see reference numeral 50 in FIG. 22). Therefore, as shown in FIG.
In the soldering of No. 0, the soldered portion of each lead wire was immersed in the solder bath up to the root of the terminal 10 in order to securely solder. However, immersing the base of the terminal 10 in the solder bath as shown in FIG. 23 also causes the substrate itself to approach the heated solder by several hundred degrees. As a result, the substrate 7 and electric components on the substrate 7 may be damaged by heat, which causes a problem that the assembled deflection yoke device cannot be used. In addition, there is a problem that the amount of solder used is increased more than necessary by soldering to the root.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be specifically described with reference to FIGS. FIG. 1 is a view showing a main part of a first embodiment of the present invention, and shows a state of a board assembly in which a connector assembly 11 is attached to a terminal 13. FIG. 2 is an enlarged view of the terminal 13 of the first embodiment.
FIG. 3 is a diagram showing a state where the lead wire 4 ′ of the vertical deflection coil 4 is wrapped around the terminal 13. FIG. 4 is a view showing a state where the lead wire 6 ′ of the 4P coil 6 is wrapped around the terminal 13. FIG. 5 is a diagram showing an example in which the terminals 13 are soldered (the solder portion is a cross section). FIG. 6 is a view of the deflection yoke device viewed from the neck side, for explaining a method of soldering the terminals 13 (the cross section of the solder bath is shown). FIG. 7 is a view showing another mode of soldering the terminal 13. FIG. 8 is a view showing still another mode of soldering the terminals 13. For example, as shown in FIG. 2, the present invention relates to a substantially columnar terminal 13 which is mounted on a substrate 7, to which a lead wire or the like is tied and soldered.
It is characterized in that flange portions 13d and 13e, which are convex portions, are provided on a cylindrical portion 13c for winding a lead wire. Accordingly, the present invention solves the problem that, in the board assembly state shown in FIG. 17, a portion where the lead wire 9 ′ of the connector wire 9 is detached from the terminal end due to a long-time vibration due to vehicle transportation or the like. Therefore, a very effective improvement effect can be obtained. In the terminal 13 of the first embodiment shown in FIG. 2, reference numeral 13a denotes a flange-shaped pedestal portion provided near the root of the terminal 13, and the root portion 1 to be fitted into the substrate.
The length of 3b is regulated. 13c is the pedestal 1 of the terminal 13
Although it is a substantially columnar portion for leading the lead wire on the tip side from 3a, the columnar portion 13c has flange-shaped protrusions 13d, 1d.
3e (hereinafter, referred to as a flange portion) is provided. In addition, the cylindrical portion 13c is separated from the flange portions 13d and 13e by 3
Is divided into two parts, and each part is
1, 13c2 and 13c3. The method of attaching the connector assembly 11 to the terminal 13 is the same as the conventional method.
Connect the lead wire 9 'of the connector wire 9 to the terminal 13 as shown in FIG.
After pulling a few times in the direction of the tip of the terminal 13 into the substantially cylindrical portion 13c1 at the base of the terminal 13, the cylindrical portion 13c
2 and wrap the lead wire 9 'several times in order to the cylindrical portion 13c3,
Finally, cut off the extra lead wires.

As a result, the entangled portion of the lead wire 9 'on the terminal 13 is slightly loosened as in the case of the conventional terminal 10. However, in the terminal 13 of this embodiment,
A flange portion 13d is provided at a portion where the lead wire 9 'is entangled.
Since the flange 13e is provided, the loosened portion of the lead wire 9 'is hooked on the flanges 13d and 13e. Therefore, in the board assembly state in which the lead wire is merely tied to the terminal, even if a long-time vibration is applied due to vehicle transportation or the like, the kinked portion as shown in FIG. There is no escape from the tip of 13. In the present embodiment, since a plurality of flange portions which are not in contact with the substrate 7 are provided on the terminal 13 so as to be separated from each other in the longitudinal direction of the terminal, the flange portion can be more reliably prevented from coming off than a single terminal, and at the same time, the lead wire can be prevented. It is also possible to reliably control the position of the kinked portion. For example, the position of the barb portion can be restricted to only the position of the cylindrical portion 13c1 or only the position of the cylindrical portion 13c2. In the terminal 13 of the present embodiment, for example, when assembling the deflection yoke device described with reference to FIG. 21, the flared portion where the lead wire 4 ′ of the vertical deflection coil 4 is flared from the terminal comes off from the tip of the terminal. It is also very effective for problems. As shown in FIG. 3, a force F is applied to the portion of the lead wire 4 ′ that is tangled to the terminal 13 by touching the lead lead-out portion 4 a of the vertical deflection coil 4, which shifts to the tip of the terminal 13. Even if lead 4 '
The flared portion is not caught by the flange portions 13 d and 13 e of the terminal 13 and does not come off from the tip of the terminal 13. Further, when a relatively thin lead wire such as the lead wire 6 'of the 4P coil 6 is tangled to the conventional terminal 10 described in FIG. The problem of concentration can also be effectively solved. As shown in FIG. 4, in the terminal 13 of the present embodiment, even if the portion where the lead wire 6 'is tied to the cylindrical portion 13c of the terminal 13 tries to shrink like a spring, the tied portion is the terminal 1
The third terminal 13 is caught by the flanges 13 d and 13 e, so that the bent portion of the lead wire 6 ′ of the 4P coil 6 does not concentrate on the base of the terminal 13 unlike the conventional terminal 10.
Therefore, as shown in FIG. 4, the cylindrical portion 13 c 3 on the most distal end side of the terminal 13 always has the connecting portion of each lead wire. Therefore, the portion to which the terminal 13 is soldered can be a bulging portion of the cylindrical portion 13c3 which is the tip portion of the terminal 13 as shown in FIG. Thereby, the distance between the liquid surface of the solder bath and the substrate 7 when soldering the terminals 13 as shown in FIG. 6 can be set to be much longer (see FIG. 6) than in the conventional case (see FIG. 23). In addition, the problem that the electric components mounted on the substrate 7 and the substrate itself, which occur when the conventional terminal 10 is used, can be solved. Further, since it is not necessary to solder to the root of the terminal, the amount of solder used can be reduced.

The above-mentioned soldering of the terminal 13 is not limited to the cylindrical portion 13c3 at the end of the terminal. If the soldering is performed up to the cylindrical portion 13c2 as shown in FIG. 7, the soldering can be performed more firmly. . Also, as shown in FIG. 8, for example, when the distance between the liquid surface of the solder bath and the substrate 7 can be set sufficiently long by providing the flange 13d on the substrate side of the terminal 13 at a position sufficiently distant from the substrate 7, as shown in FIG. May be soldered to the position of the cylindrical portion 13c1 on the substrate side. Also, considering only from the viewpoint of preventing the bulging portion from coming off from the terminal 13, at least the portion of the terminal 13 between the flange portion 13 e, which is the outermost projection as viewed from the substrate 7, and the substrate 7. Since the lead wire only needs to be tangled, the cylindrical portion 1
It may be wrapped around only the column 3c1 or the column 13c2. The flange portions 13d and 13e provided on the cylindrical portion 13c of the terminal 13 shown in FIG. 2 may be provided as protrusions so that the kinked portion of the lead wire does not shift in the longitudinal direction of the terminal. Flange portion 14 of terminal 14 of second embodiment
d, 14e and 14f may be provided.
Like the terminal 16 of the third embodiment shown in FIG. 0, the protrusions 16d and 16e may be provided apart from each other in the longitudinal direction and the circumferential direction of the terminal 16.

Although the flange portions 13d and 13e of the terminal 13 described with reference to FIG. 1 are formed so as to raise a part of the cylindrical portion 13c, like the terminal 17 of the fourth embodiment shown in FIG. The grooves (recesses not in contact with the substrate 7) 17d and 17e into which the lead wires are inserted so that the lead wires connected to the columnar portion 17c do not move in the longitudinal direction of the terminal may be provided, as shown in FIG. The constriction 18d may be long enough in the longitudinal direction of the terminal as in the terminal 18 in the example. The lead is to be stripped at least over a portion of the recess.

[0012]

As described above, in the deflection yoke device of the present invention, in a state where the lead wire is merely wound on the terminal on the substrate, the deflection yoke device may be subjected to long-time vibration or deviation toward the tip end of the lead wire of the terminal. Even if a force is applied, it is possible to securely prevent the lead wire from coming off the terminal. Therefore, the deflection yoke device according to the present invention does not require useless work of tying and healing the lead wire to the terminal, thereby greatly improving productivity. Further, in the deflection yoke device of the present invention, the position of the tang portion of the lead wire can be reliably regulated by the convex portion or the concave portion of the terminal.
