じれ断線が発生する虞れがある。(c) Problems to be solved by the invention However, when the connecting part 12 is screwed into or removed from the cylindrical part 11, the lead wire 15 also rotates, and the board 13 also rotates accordingly. but,
As shown in FIG.
If it comes into contact with the inner end 14a of the connector, this rotation will be blocked, and there is a risk that the lead wire 15 between the connecting portion 12 and the substrate 13 will be twisted and broken.
尚、絶縁シート１４の内側端１４ａが基板１３
の回転力によつて折れ曲がらないように、この絶
縁シート１４の剛性を大きくしている。 Note that the inner end 14a of the insulating sheet 14 is connected to the substrate 13.
The rigidity of the insulating sheet 14 is increased so that it does not bend due to the rotational force of the insulating sheet 14.
(ニ) 問題点を解決するための手段
本考案は、絶縁シートの内側端を凸形状に成形
すコネクタである。(d) Means for solving the problems The present invention is a connector in which the inner end of an insulating sheet is formed into a convex shape.

Note that the same parts as in FIGS. 7 to 11 are given the same reference numerals. In the figure, 20 is an insulating sheet with one end 21 formed into a convex shape. Then, an insulating sheet is wound and installed in the cylindrical part 11 so that this one end 21 is on the inside.
