TERMINAL CONNECTION STRUCTURE

To provide a terminal connection structure capable of regulating movement of a rod-like part after mating suitably, while reducing insertion force during insertion of a male terminal.SOLUTION: A terminal connection structure 1 includes a male terminal 10 having a columnar rod-like part 11, a female terminal 20 having a cylinder part 21 into which the rod-like part 11 of the male terminal 10 is inserted, and an elastic member 30 attached in the cylinder part 21 of the female terminal 20, and energizing the rod-like part 11 of the male terminal 10 when the rod-like part 11 of the male terminal 10 is inserted into the cylinder part 21 of the female terminal 20. The elastic member 30 has multiple leaf springs 33 bending inward of the cylinder part 21, where the position of the maximum protrusion protruding most to the inside of the cylinder part 21 by bending inward of the cylinder part 21 is misaligned for other leaf springs 33 in the axial direction of the cylinder part 21.SELECTED DRAWING: Figure 1 【課題】雄端子の挿入時における挿入力の低減を図りつつも、嵌合後における棒状部の動きを好適に規制することが可能な端子接続構造を提供する。【解決手段】端子接続構造１は、円柱形状の棒状部１１を有する雄端子１０と、雄端子１０の棒状部１１が挿入される筒部２１を有する雌端子２０と、雌端子２０の筒部２１内に取り付けられ、雄端子１０の棒状部１１が雌端子２０の筒部２１に挿入された場合において、雄端子１０の棒状部１１を付勢する弾性部材３０とを備え、弾性部材３０は、筒部２１の内側に向かって湾曲した複数の板バネ３３を有し、複数の板バネ３３は、筒部２１の内側への湾曲により最も筒部２１の内側に突出した最大突出部の位置が他の板バネ３３に対して、筒部２１の軸方向にずれている。【選択図】図１
