【考案の詳細な説明】
本考案は、中間周波変成器や済波器などの如き小型高周
波コイルに内蔵されている同調用コンデンサの格納に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the storage of a tuning capacitor built into a small high frequency coil such as an intermediate frequency transformer or a transducer.

ためベースに格納できる数も2個程度に限られるという
欠点がある。The tuning capacitor built into such a high-frequency coil is generally housed in a recess provided at the bottom of the base of the coil, and its lead wire is tied to a terminal pin and soldered. Since there is a process of attaching them to pins, this is disadvantageous in terms of mass production, and since the size is relatively large, the number that can be stored in the base is limited to about two.

接続するには色々な工夫が必要になってくる。In order to improve these drawbacks, it is desirable to use small, large-capacity chip capacitors as tuning capacitors from the viewpoint of product miniaturization and performance improvement. Since it only has electrodes exposed at both ends and does not have lead wires like normal ones, various ingenuity is required to connect it to the terminal pin of the high-frequency coil.

ようにしたものである。The present invention allows such chip capacitors to be easily temporarily attached between terminal pins before soldering, thereby improving the mass productivity of capacitor mounting work and stably attaching chip capacitors without lead wires. It is designed so that it can be installed on.
以下、本考案を図面について説明する。Hereinafter, the present invention will be explained with reference to the drawings.

コンデンサを直接挾持させ、その状態でチップコンデン
サの電極7と端子ピン2とが半田付けされている。In the figure, 1 indicates the base of the coil, and 2 indicates the terminal pin embedded in it. However, in the present invention, a part of the terminal pin 2 to which the capacitor is connected is processed by crushing, bending, etc. The chip capacitor 4 is directly sandwiched between the terminal pins by fitting the end of the chip capacitor 4 into the recess of the bump 3, and in this state, the electrode 7 of the chip capacitor and the terminal pin 2 are connected. It is soldered.
なお、チップコンデンサ4を格納する場所は、第1図の
ように、ベース1の底面に設けた凹部5でもよいし、ま
た第2図のように、ベース1の側面に設けた凹部5′(
穴または溝)でもよい。The chip capacitor 4 may be stored in the recess 5 provided on the bottom of the base 1 as shown in FIG. 1, or in the recess 5' (provided on the side surface of the base 1 as shown in FIG.
hole or groove).
但しチップコンデンサはきわめて小型でうすいものであ
るから、必ずしも凹部に格納するとは限らず、例えばベ
ース1の底面にそのま\取付けることもできる。However, since the chip capacitor is extremely small and thin, it is not necessarily necessary to store it in the recess, and for example, it can be attached directly to the bottom surface of the base 1.
第3図ないし第5図は、端子ピン2の一部に曲げ加工を
施して凹凸部3を形成させた例であり、また第6図と第
7図は端子ピンの一部をつぶして凹凸部3を作った例を
示す。Figures 3 to 5 show examples in which a portion of the terminal pin 2 is bent to form an uneven portion 3, and Figures 6 and 7 are examples in which a portion of the terminal pin 2 is bent to form an uneven portion 3. An example of creating part 3 is shown below.
また、チップコンデンサの両端部を接続する2本の端子
ピンのうちの片方は、第8図に示す如く通常の端子ピン
2′を用いてもよい。Furthermore, one of the two terminal pins connecting both ends of the chip capacitor may be a normal terminal pin 2' as shown in FIG.

取付は作業を量産的に行なえるという効果がある。Even if the terminal pin 2 falls down, the end of the chip capacitor 4 can be easily fitted into the recess of the uneven part 3 of the terminal pin 2 and temporarily attached using the elasticity of the terminal pin 2. The process of temporarily attaching the capacitor can be omitted, and the capacitor mounting process can be carried out in mass production.
また、リード線のないチップコンデンサ4を安定的に取
付けできるという利点もある。Another advantage is that the chip capacitor 4 without lead wires can be stably mounted.
なお、図中6は端子ピンとチップコンデンサとを接続し
