Patent ID: 7789722

Claim:
A terminal connecting structure for first and second plated terminals to be connected by at least partly inserting a tab of the first terminal into a tube of the second terminal comprising: a resiliently deformable resilient contact piece in the tube and including a contact with a female contact surface for contacting the tab inserted into the tube; the tab moving forward in the tube while resiliently deforming the resilient contact piece by sliding a male contact surface of the tab in contact with the female contact surface of the contact and the terminals being connected properly when the tab moves forward to a specified depth in the tube; at least one groove formed in a part of the female contact surface that slides in contact with the tab or in a part of the male contact surface that slides in contact with the female contact surface, wherein the groove intersects the respective male or female contact surface at lateral edges extending obliquely to an inserting direction of the tab, and a position of the groove defining a maximum width of the groove is at a starting point where the contact with the contact or the tab starts, and a rear end position of the groove defines an ending position for sliding contact with the contact or the tab.
