Abstract
Abstract A housing has a groove-like terminal-receiving cavity. The terminal-receiving cavity receives a female terminal therein. The female terminal has a first engagement portion at a longitudinal end thereof and a second engagement portion at a longitudinally intermediate position thereof. The terminal-receiving cavity is formed with a third engagement portion therein at one longitudinal end thereof, the third engagement portion engaging the first engagement portion when the terminal is fully inserted into the terminal receiving cavity. The terminal-receiving cavity is formed with a fourth engagement portion at a longitudinally intermediate position thereof, the fourth engagement portion engaging the second locking portion when the terminal is fully inserted into the terminal receiving cavity. When assembling the terminal into the terminal-receiving cavity, the first engagement portion of the terminal is first engaged the third engagement portion and thereafter the terminal is pivotally rotated about an engagement between the first and third engagement portions into the terminal-receiving cavity unit the second engagement portion firmly engages the fourth engagement portion.
