TERMINAL CONNECTION UNIT

To hold a conducting wire with a leaf spring in a more secure manner.SOLUTION: A terminal connection unit 10 includes: a housing; a terminal hole 15 which guides a conducting wire from an exterior of the housing to an interior; an operation hole 16 which guides a driver 20 from the exterior of the housing to the interior; a terminal plate 36 having a conductive contact part 36a which contacts with the conducting wire 12 inserted into the terminal hole 15; and a leaf spring 38 which biases the conducting wire 12 to the conductive contact part 36a side with an elastic force and which is located on an extension line of a center axis of the operation hole 16. The terminal plate 36 has a bent piece 36b which is bent from a tip of the conductive contact part 36a and is parallel to the conductive contact part 36a in an F1 direction in which the leaf spring 38 presses. The housing includes: a front wall 26b supporting the bent piece 36b from the back side in the F1 direction; and a front wall 28b supporting the conductive contact part 36a from the back side in the F1 direction. A protruding part 18 of the bent piece 36b is press-fitted in an input hole 34 of an additional unit.SELECTED DRAWING: Figure 5 【課題】板バネによる導線の保持を一層確実に行う。【解決手段】端子接続ユニット１０は、ハウジングと、ハウジングの外部から導線を内部に導く端子孔１５と、ハウジングの外部からドライバ２０を内部に導く操作孔１６と、端子孔１５に挿入された導線１２と接触する導電接触部３６ａを有する端子板３６と、導線１２を弾性力により導電接触部３６ａ側に付勢し、操作孔１６の中心軸の延長線上に位置する板バネ３８とを備える。端子板３６は、導電接触部３６ａの先端から折り曲げられて、板バネ３８が押圧するＦ１方向について導電接触部３６ａと並列する折曲片３６ｂを有する。ハウジングは、Ｆ１方向について折曲片３６ｂを裏側から支持する前壁２６ｂと、Ｆ１方向について導電接触部３６ａを裏側から支持する前壁２８ｂとを備える。折曲片３６ｂの突出部１８は、付随ユニットの入力孔３４に圧入する。【選択図】図５
