Description
【考案の詳細な説明】
本考案は、たとえば中間周波変成器やろ波器などのよう
に、同調コンデンサを内蔵した高周波コイルに関するも
のである。[Detailed Description of the Invention] The present invention relates to a high frequency coil having a built-in tuning capacitor, such as an intermediate frequency transformer or a filter.

場合は、細かいコイルのリード線５が引張られて断線す
るという事故がおきやすい。As shown in FIG. 1, such a high-frequency coil generally has a tuning capacitor 7 built into the base 2 of the coil bobbin 1, and the coil 8 is wound around the lead wire 6 of the tuning capacitor 7, which is wrapped around the base of the terminal pin 3. As a result, the lead wire 5 of the coil 8, which is later tied to the terminal pin, is slightly raised from the bottom of the base due to the relatively thick capacitor lead wire 6, as shown in Figure 2, and is not printed. If the terminal pin is moved in the direction of arrow A when inserting it into the circuit board, the fine coil lead wire 5 is likely to be pulled and broken.
本考案の目的は、このような断線事故を防止して高周波
コイルの信頼度を高めることにある。The purpose of the present invention is to prevent such disconnection accidents and increase the reliability of high-frequency coils.

けてからげたコイルのリード線の上に、同調コンデンサ
のリード線６をからげて半田付けしたものである。The present invention, as illustrated in FIG.
A recessed hole 4 is provided around the base of the terminal pin 3, and a guide groove 4' is provided in the recessed hole 4 to pass the coil lead wire through. The lead wire 6 of the tuning capacitor is twisted and soldered onto the lead wire of the coil that is twisted from the vicinity of the entrance of the recessed hole 4 to the outside.
なお、図中９は半田、１０はベース側面に設けた周゛知
のリード用溝を示す。In the figure, 9 indicates solder, and 10 indicates a well-known lead groove provided on the side surface of the base.
以上の如く、コイルのリード線５のからげ部の一部を凹

状態にあるため、端子ピン３を動かしてもコイルのリー
ド線５が緊張することがなく、したがって断線すること
もない。As described above, when a part of the tangled part of the coil lead wire 5 is pushed into the inside of the recessed hole 4, the coil lead wire 5 is wired with some slack at the bottom of the guide groove 4'. Furthermore, since the portion that has entered the recessed hole 4 is in a free state without being soldered, the coil lead wire 5 will not be tensed even if the terminal pin 3 is moved, and therefore will not be disconnected.
また、同調コンデンサの太目のリード線６が凹穴４の入
口をふさいで、半田９の凹穴４への流入を防ぐと共に内
部のコイルのリード線５を保護するという効果もある。Further, the thick lead wire 6 of the tuning capacitor blocks the entrance of the recessed hole 4, thereby preventing solder 9 from flowing into the recessed hole 4 and protecting the lead wire 5 of the internal coil.

た高周波コイル。The base 2 of the coil bobbin 1 is provided with a recessed hole 4 that leaves the base of the terminal pin 3 blank and a guide groove 4' through which the coil lead wire is passed. This is a high-frequency coil in which a part of the lead wire 5 of the tuning capacitor is inserted, and a lead wire 6 of a tuning capacitor is tied and soldered onto the lead wire 5 of the coil, which is twisted from the vicinity of the entrance of the recessed hole 4 to the outside.
