【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In the description of the present embodiment, the same reference numerals will be given to the same names as those in the proposed example, and detailed description thereof will be omitted. FIG. 1 shows an explanatory view of the main configuration of the deflection yoke device according to this embodiment. A characteristic of this embodiment is that the wiring terminals 10 provided on the lead-out path of the lead-out lead of the deflection yoke device are configured to have a pair of elastic plates 15 facing each other and pressed against each other. The opposing pressure contact surfaces of the pair of elastic plates 15 are holding surfaces for the extraction leads.

Similar to the proposed example, the deflection yoke device of the present embodiment is provided with enlarged diameter portions 4a and 4b on the head side and the neck side, and a pair of FC coils 6 and a pair of FC coils 6 are provided on the enlarged diameter portion 4b side. A pair of SSC coils 13 and the like are arranged. Further, a circuit board 5 is laid over the head side and the neck side of the bobbin 2, and a conductor pattern of a wiring circuit is formed on the circuit board 5 to mount electronic components. A plurality of the wiring terminals 10 (10A, 10B, 10C) are formed on the circuit board 5, and the wiring terminals 10 are pressed against each other as shown in FIG. 2 (a). A pair of flat plate-like elastic plates 15 are arranged to face each other, and the opposing surfaces of the pair of elastic plates 15 serve as holding surfaces 17 for the lead-out lead. Further, a taper 16 is provided on the edge side of the wiring terminal 10 to facilitate insertion of a lead.

Next, the operation of wiring the lead wire of the deflection yoke according to this embodiment will be described. First, the lead-out lead 11 of the vertical deflection coil is drawn out to the neck side of the deflection yoke device, and the tip of this lead-out lead 11 is inserted into the wiring terminal 10A arranged on the circuit board 5. In this wiring terminal 10A, the lead-out lead 11 is held in pressure contact by the pressure contact surface 17 of the pair of elastic plates 15. After that, solder or the like is fused to the pressure contact holding portion, and the lead 11 is connected to the conductor pattern of the wiring circuit via the wiring terminal 10A. The lead 11 is connected to the FC coil 6 and the like via the wiring terminal 10A.

Further, the lead-out lead 12 of the horizontal deflection coil is led out to the neck side, and like the lead-out lead 11 of the vertical deflection coil, the lead-out lead 12 is inserted into the wiring terminal 10 of the circuit board 5 and soldered.

According to the present embodiment, the lead-out leads 11 and 12 of the vertical deflection coil and the horizontal deflection coil are simply inserted into the wiring terminals 10 (10A, 10B and 10C) to hold the lead-out leads 11 and 12 under pressure. As a result, unlike the proposed example, it is not necessary to tie the lead-out leads 11 and 12 to the connection terminal 9 one by one, and the lead-out leads 11 and 12 can be wired at the shortest distance instead of hanging in the aerial wiring. Therefore, the assembly can be simplified and the wiring work can be automated, and the work efficiency can be significantly improved.

Further, in the above-described embodiment, the wiring terminal 10 is configured by using a pair of flat plate-like elastic plates as shown in FIG. 2A. However, for example, in FIG. As described above, the elastic plates 15 facing each other may be formed with the uneven surface 14 and the uneven surfaces 14 may be engaged with each other. When a lead-out lead is inserted into this terminal 10, the outer peripheral surface of the lead is damaged by the engagement of the uneven surface 14 of the elastic plate 15 and is held in pressure contact. It has been found that when the solder is poured into the pressure contact holding portion of the lead wire having the scratch, the heat of the solder is easily transferred from the scratch portion of the lead wire 11, and the soldering on the scratch portion is extremely good.

Further, in the above-mentioned embodiment, the lead-out leads 11 and 12 of the vertical deflection coil and the horizontal deflection coil are directly led to the wiring terminals 10 of the circuit board 5 to be inserted and wired, but for example, as shown in FIG. , A relay wiring terminal 10D is provided at an arbitrary position on the outer peripheral wall surface of the lid-shaped bobbin 8, and the lead-out lead 11 pulled out to the neck side is once inserted into the relay terminal 10D to temporarily fix the solder, and then the relay terminal The lead 11 may be led out to the wiring terminal 10A of the circuit board 5 by inserting 10D as a relay point, and may be inserted and soldered.

Furthermore, in the above embodiment, the lead-out lead 12 of the horizontal deflection coil is led out to the neck side, and the lead-out lead 12 is inserted and connected to the wiring terminal 10B of the circuit board 5. May be pulled out to the head side and inserted and connected to the wiring terminal 10C on the head side of the circuit board 5. In addition, a relay terminal 10E may be provided on the outer peripheral wall side of the head side enlarged diameter portion 4a, and the lead lead 12 may be inserted into the relay terminal 10E to temporarily fix the solder.

[Effect of device]

 Since the present invention has a structure in which the lead-out lead is pressed and held only by inserting the lead-out lead into the wiring terminal provided in the lead-out path of the lead-out lead, the lead-out lead can be individually attached to the connection terminal as in the proposed example. This eliminates the need for automation of wiring work and greatly improves work efficiency.
