Terminal fitting connecting structure

A terminal fitting connecting structure, comprising:

• a female terminal (20) including a connecting tube (23), contact portions (36) being provided at positions substantially equidistant from a leading end of the connecting tube (23) on substantially facing surfaces of the connecting tube (23), the contact portion (36) on at least at one side being provided on a resilient contact piece (35) on the facing surface;
• and
• a male terminal (10) including a tab (13) with opposite front and rear ends spaced apart along forward and rearward directions (FBD) and configured for insertion into the connecting tube (23), the tab (13) resiliently contacting the contact portions (36) by being inserted between and contacting the contact portions (36) while resiliently displacing the resilient contact piece (35) so that the contact portions (36) sandwich the tab (13) in a thickness direction (TD), the tab (13) having a tip at the front end of the tab (13), flat surfaces (14A) on opposite sides of the tab (13) and spaced from the tip and inclined surfaces (15, 16) extending from the respective flat surfaces (14A) to the tip and gradually converging toward the tip, base end edges (15A, 16A) being defined on ends of the inclined surfaces (15, 16) adjacent the flat surfaces (14A), the respective inclined surfaces (15, 16) being formed so that positions where the respective base end edges (15A, 16A) connect to flat surfaces (14A) differ in the forward and backward directions (FBD).
