TERMINAL CONNECTION STRUCTURE

To provide a terminal connection structure capable of securing holding power while suppressing an insertion force low.SOLUTION: A terminal connection structure comprises: a male terminal fitting including a male connector; a female terminal fitting 20 including a female connector 21; and a holding structure 30 which generates holding power therebetween. The holding structure includes: two first holders 31 which are disposed between the male connector and the female connector in an area A1 and become contacts therebetween; two second holders 32 which are disposed between the male connector and the female connector in an area A2 and become contacts therebetween; and a third holder 33 which is disposed at a reverse side of the first holders in a tube axis direction with respect to the second holders and becomes a contact between the male connector and the female connector. The first holders are disposed at the side of a first opening 21a and in areas A1a and A1b. The second holders are disposed at a second opening side and in areas A2a and A2b. The third holder is disposed so as to be positioned between the first holders in a view in the tube axis direction.SELECTED DRAWING: Figure 3 【課題】挿入力を低く抑えつつ保持力を確保することが可能な端子接続構造を提供する。【解決手段】雄型接続体を有する雄端子金具と、雌型接続体２１を有する雌端子金具２０と、これらの間で保持力を発生させる保持構造体３０とを備え、保持構造体は領域Ａ１で雄型接続体と雌型接続体との間に配置され、かつ、その間での接点となる２つの第１保持体３１と、領域Ａ２で雄型接続体と雌型接続体との間に配置され、かつ、その間での接点となる２つの第２保持体３２と、第２保持体に対して筒軸方向で第１保持体とは逆側に配置され、雄型接続体と雌端子金具との間での接点となる第３保持体３３とを備え、それぞれの第１保持体は、第１開口２１ａ側で、かつ、領域Ａ１ａ，Ａ１ｂに各々配置し、それぞれの第２保持体は第２開口側で、かつ、領域Ａ２ａ，Ａ２ｂに各々配置し、第３保持体は筒軸方向に見て、それぞれの第１保持体の間に位置させるように配置する。【選択図】図３
