クタンス可変機構を有する高周波コイルに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high frequency coil having a variable inductance mechanism used in electronic equipment such as televisions and videos.
従来の技術
従来のこの種高周波コイルは、例えば実公昭６６−２２
７４６号公報に示されているように、第３図のような構
造になっていた。2. Prior Art A conventional high frequency coil of this type is, for example,
As shown in Publication No. 746, it had a structure as shown in FIG.
すなわち、端子１を植設した端子板２上にポビ６を螺合
挿入しネジコアらを上下動にエリコイル部７のインダク
タンスを可変してなる高周波コイルにおいて、端子板２
に段部２′を形成し、シールドケース４に設けた内方へ
の突出部４′により上記段部２′ヲ係正し、一方端子板
２にとりつけたボビン３の上部鍔３′の上面と７−ルド
ケース天井部に当接させることにより端子板を固定する
ものであった。That is, in a high-frequency coil formed by screwing and inserting the povi 6 onto the terminal board 2 on which the terminal 1 is implanted, and changing the inductance of the eli coil part 7 by moving the screw core and the like up and down, the terminal board 2
A step 2' is formed on the shield case 4, and the step 2' is fixed by an inward protrusion 4' provided on the shield case 4. On the other hand, the upper collar 3' of the bobbin 3 attached to the terminal plate 2 The terminal board was fixed by bringing it into contact with the ceiling of the case.
発明が解決しようとする問題点
しかし、このような構造のものではシールドケース４の
天井部から突出部４′までの寸法精度及び突出部の形状
等に工９端子板取付が完全に行なわれず、がたを生ずる
おそれがある。Problems to be Solved by the Invention However, with such a structure, the dimensional accuracy from the ceiling of the shield case 4 to the protruding part 4' and the shape of the protruding part cannot be ensured, and the terminal board cannot be completely attached. There is a risk of rattling.
そこで、本発明はシールドケースの天井部から突出部ま
での寸法精度が出なくても、きわめて簡単な構造で端子
板を安定確実に保持し得るようにするものである。Therefore, the present invention is intended to make it possible to stably and reliably hold a terminal board with an extremely simple structure even if the dimensional accuracy from the ceiling part to the protruding part of the shield case is not achieved.
問題点を解決するための手段
そして上記問題点を解決する本発明の技術的な手段は、
上記シールドケースの上面に中央部に向って切込みを形
成して内方へ曲る弾性舌片全役けるものである。Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
A notch is formed in the upper surface of the shield case toward the center to serve as an inwardly curved elastic tongue.
作 用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.
すなわち、７−ルドケース上部の弾性舌片より突出部ま
での距離を、ボビン鍔上面から端子板段部までの距離よ
り短くすることで、ボビン鍔は弾性舌片の弾性力で圧接
され、その下部にある端子板は、がｆｃを生ずることも
ない。In other words, by making the distance from the elastic tongue on the upper part of the 7-fold case to the protrusion shorter than the distance from the top surface of the bobbin collar to the stepped part of the terminal plate, the bobbin collar is pressed by the elastic force of the elastic tongue, and its lower part The terminal board located at the terminal will not cause fc.
実施例
以下１本発明の一実施例を添付の第１図、第２図の図面
にもとづいて説明する。Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings of FIGS. 1 and 2.
第２図において、端子８を植設した端子板９上にポビン

被せボビン１０に形成したボビン中空部１２にネジコア
１３を螺合挿入しネジコア１３を上下動によりコイル部
１４のインダクタンスを９変してなる構造である。In FIG. 2, a pobbin 10i is formed on the terminal plate 9 on which the terminal 8 is implanted, a shield case 11 is placed over the bobbin 10, and a screw core 13 is screwed and inserted into the bobbin hollow part 12 formed in the bobbin 10. It has a structure in which the inductance of the coil portion 14 is changed by 9 by vertical movement.
７−ルドケース１１の上面に中央部に向って切込み１６

面を下方に圧接している。第１図は略図金示している。7- A cut 16 is made on the top surface of the lead case 11 toward the center.
is provided to form an elastic tongue piece 16, and this elastic tongue piece 16 is bent inward. Numeral 17 is a spherical protrusion that is provided approximately at the center of the terminal plate 9 from the tip of the notch 16 and protrudes inwardly. The elastic force of the piece 16 presses the upper surface of the bobbin collar 18 downward. FIG. 1 is a schematic diagram.
すなわち、端子板９をシールドケース１１の下部に取付

ケース１１の開口縁近傍に設けた突起１７に係止させる
ため弾性舌片１６が常時ボビン鍔１８の上面を下方に押
圧する形をとり端子板９はがたなく強固に保持されるも
のである。That is, when attaching the terminal plate 9 to the lower part of the shield case 11, the terminal plate 9 is attached from below the shield case 11.
The upper surface of the terminal plate 9, that is, the upper surface of the bobbin collar 18, comes into contact with the tip of the elastic tongue piece 16, and after t, the terminal plate 90 is further pushed up so as to move the stepped portion 19 of the terminal plate 90 near the opening edge of the shield case 11. The elastic tongue piece 16 is always pressed downwardly against the upper surface of the bobbin collar 18 so that the terminal plate 9 can be firmly held without wobbling.
発明の効果
以上のように本発明は、きわめて簡単な構成で、端子板
を安定確実に保持でき、しかも端子板は、弾性力で圧接
されているのでがたを生ずることもない。Effects of the Invention As described above, the present invention has an extremely simple structure and can hold the terminal plate stably and reliably, and furthermore, since the terminal plate is pressed against the elastic force, no wobbling occurs.
