４が割れだりするおそれがあった。Problems to be Solved by the Invention However, with such a structure, fixing the sleeve core 4 is time-consuming and difficult to work with, and furthermore, depending on the amount of adhesive applied, the fixing may not be completed completely and may cause wobbling. There is. Furthermore, due to the dimensional accuracy from the ceiling of the shield case 5 to the protruding part 5' and the shape of the protruding part 5', there is a risk that the terminal board 2 may not be completely installed, resulting in looseness or cracking of the sleeve core 4. was there.
そこで、本発明はスリーブコアを接着剤等で固定しなく
ても、きわめて簡単な構造でスリーブコアを固定し、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 fix the sleeve core with an extremely simple structure without using an adhesive or the like to hold the terminal board stably and reliably.
問題点を解決するだめの手段
そして上記問題点を解決する本発明の技術的な手段は、
スリーブコアを螺合させるコア保持モールドの下部に下
方へ突出する弾性舌片を設けるものである。Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
An elastic tongue protruding downward is provided at the lower part of the core holding mold into which the sleeve core is screwed.
作用 この技術的手段による作用は、次のようになる。action The effect of this technical means is as follows.

の弾性力で圧接されがたを生ずることもない。That is, the sleeve core is fixed within the core holding mold by press-fitting the sleeve core from the top or bottom into the core holding mold, which has ribs for fixing the sleeve core on its inner surface. An elastic tongue piece that protrudes downward is provided at the bottom of this core holding mold, and the dimension from the top of the core holding mold to the elastic tongue piece is determined from the dimension from the ceiling of the shield case to the protrusion at the bottom of the shield case. By making the terminal board longer than the dimension r obtained by subtracting the dimension from the upper part of the terminal board to the step part of the terminal board, the terminal board will not be pressed by the elastic force of the elastic tongue of the core holding mold and will not cause any backlash.
