きる状態となる。FIGS. 8A and 9B are a perspective view and a cross-sectional view showing the mutual relationship between the male terminal F at the temporary locking position and the final locking position of the terminal locking tool E, respectively. . The mechanism of the temporary locking and the final locking of the terminal locking member E with respect to the connector housing D is the same as that in the case of FIGS. In the temporary locking position of the terminal locking tool E,
Since the terminal locking portions 22 provided on each of the wall pieces 20 and 21 and the side plate portion 8 'are separated from the corresponding terminal accommodating chamber 1' (in the illustrated example, they are located above the terminal accommodating chamber 1 '). The male terminal F can be inserted and removed from the rear of the connector housing D.

様である。When the male terminal F is inserted into the terminal accommodating chamber 1 'at the temporary locking position, as shown in FIG. 9A, the flexible lock arm 16' in the terminal accommodating chamber 1 'is brought into contact with the electric contact portion. It engages the F 1 of the locking hole 18 'for the primary locking of the terminal. In this state,
When the terminal locking member E is moved to the final locking position, the wall pieces 20 (or the wall pieces 21 and the side plate portions 8 ') on both sides of each male terminal F are moved.
The terminal locking portion 22 provided on a state of engagement therewith are located behind the locking pieces 23 in the electrical contact portion F 1, double locking of the terminal is achieved. Note that the unlocking of the terminal locking tool E may be performed in the reverse procedure. Further, the terminal locking member E can be applied to a male connector housing for accommodating the female terminal C as in the case of the first invention.
