is rectangular in shape, with a through hole 8 having a U-shaped cross section in the left and right direction.
A has vertical holes 8b on its upper surface, and a pair of grooves 8c on its front and rear outer surfaces. Five pin-shaped terminals 11 are implanted on the lower surface of the substrate 8.

It is wound and fixed to the terminal 11 via the groove 8c. At this time, if the tension of the lead wire 14 is made strong, the capacitor 10
is fixedly positioned within the hole 8a without wobbling.
Further, when the capacitor 10 is inserted into the hole 8a and stored, the holding plate portion 13 of the bobbin 10 only protrudes parallel to the insertion direction and does not get in the way.

くして高周波コイル１が完成する。 The thus completed coil unit 7 is case 2.
When installing the case 2, the board 8 is inserted from the bobbin 9 side until the top surface of the case 2 comes into contact with an inner cut-and-raised part (not shown), and then the bottom end of the case 2 is moved toward the bottom surface of the board 8 and locked. At this time, the pair of presser plate parts 13 abut against the lower end of the side wall 5 of the case 2, and the flexible part 1
3a deforms and is restricted from bending downward, unit 7
After fitting, as shown in FIG. 1, it covers both end surfaces of the capacitor 10, covers part of the openings at both ends of the through hole 8a, and is interposed between both end surfaces of the capacitor 10 and the side wall 5 of the case 2. (The holding plate part 13 can be rotated slightly until it comes into contact with the side wall 5.) Therefore, even if the lead wire 14 becomes loose due to its pulling out, poor wiring work, or external shock, and becomes misaligned with the capacitor 10, , it is shielded by the holding plate part 13 and does not come into contact with the case 2 and shoot. In this way, the high frequency coil 1 is completed.

付け固定出来るという特長を有するものである。 As mentioned above, according to the high frequency coil of the present invention, the insulating plate portion is interposed between both end surfaces of the capacitor provided in the through hole of the substrate and the side wall of the metal case, so that the lead wire of the capacitor is Even if the capacitor becomes loose due to a wiring mistake or an external shock, the lead wire and capacitor are shielded by the insulating plate and there is no risk of them hitting the case and being shot, improving the reliability of the circuit. Also, since the insulating plate part is integrally molded with the coil bobbin, there are no additional parts and the configuration is simple. Furthermore, since the insulating plate part is formed to be bendable, it is extremely thin. As a result, the space for accommodating the capacitor can be made relatively large, and a large-sized capacitor, that is, a capacitor with a large capacitance, can be provided, which is advantageous when setting the resonance frequency low. Since the capacitor is housed in a through hole formed in the board so that the left and right sides are open, the capacitor is not exposed on the bottom of the board.
When fixing the high frequency coil to the printed circuit board by soldering, it is possible to reliably prevent flux and even molten solder from adhering to the capacitor, and therefore the capacitor can be soldered and fixed to the printed circuit board without the risk of damaging it. It is something.
