３を固定する。In the high frequency equipment configured as described above, the metal fitting 3a
Insert the small diameter portion into the opening 1a of the shield case 1. Next, this feedthrough capacitor 5 is temporarily fixed in a fixed position using a jig. By heating in this state, the washer solder 4 is melted and the feedthrough capacitor 3 is fixed to the shield case 1.
発明が解決しようとする課題 上記の様な高周波機器においては次の課題があった。Problems that the invention aims to solve High frequency equipment such as the one described above has the following problems.
すなわち、上記貫通形コンデンサ３をシールドケース１

具を用いて設置している。この治具は、貫通形コンデン
サ３の位置決めのみならず、シールドケース１の固定も
行わなければならないので大がかりなものとなってしま
う。That is, the feedthrough capacitor 3 is placed in the shield case 1.
When soldering, the feedthrough capacitor 3 is first placed in a fixed position in the opening 1a using a jig. This jig is large-scale because it must not only position the feedthrough capacitor 3 but also fix the shield case 1.
従って本発明は、この治具を廃止し、生産性を高めるこ
とを目的とするものである。Therefore, the present invention aims to eliminate this jig and increase productivity.
課題を解決するための手段
この目的を達成する為に本発明は、開孔部の外周を切り
起こして爪を設け、この爪の先端を貫通形コンデンサに
当接させたものである。Means for Solving the Problems In order to achieve this object, the present invention provides a claw by cutting and raising the outer periphery of the opening, and the tip of the claw is brought into contact with a feedthrough capacitor.
作用
以上の手段によれば、治具を用いなくても、爪によって
貫通形コンデンサが爪とは反対側の開孔縁に当てられて
定位置に保持させるので、容易に半田付することが出来
、生産性の高いものとなる。According to the method described above, the through-type capacitor can be easily soldered without using a jig because the nails hold the through-hole capacitor in place by applying it to the edge of the hole on the opposite side of the nails. , resulting in high productivity.

ことによって第３図に示す様な爪８が形成されている。Embodiment In FIG. 1, reference numeral 5 denotes a rectangular shield case, and a high frequency circuit 6 is provided inside this shield case 5. A circular opening 7 is provided on one side of the shield case 5, as shown in FIG. A claw 8 as shown in FIG. 3 is formed by cutting and raising it.
この爪８の先端は根元よりも若干細く形成されている。The tip of this claw 8 is formed to be slightly thinner than the base.

数個設けることも考えられる。In this state, the small diameter portion of the feedthrough capacitor 9 is inserted into the opening 7. This feedthrough capacitor 9 is composed of a metal fitting 9a having a two-stage configuration, a core wire 9b passing through the center of the metal fitting 9a, and an insulator 9c provided between them. In this configuration, the small diameter part of the metal fitting 9a is inserted into the aperture 3, and when this insertion is carried out, the outer periphery of the large diameter part is held down by the claws 8 as shown in FIG. The feedthrough capacitor 9 is inserted as follows. The feedthrough capacitor 9 is inserted into the opening 3 at a slight inclination, and the rear end of the large diameter portion of the metal fitting 9a is press-fitted until it is sandwiched between the claws 8. In this state, the feedthrough capacitor 9 comes into contact with the edge of the hole 3 on the side opposite to the claw 4 and is temporarily fixed. Therefore, in this fixed position, the washer solder 10
It can be fixed extremely easily. Note that it is also possible to provide a plurality of claws 8.
