the process for disconnecting the female terminal from the resilient locking arm 8 that is pushing the terminal extracting block b by a driver d or a finger causes the point r of the resilient locking arm 8 to slidably move on the arm disconnecting face 12a which permits the arm 8 to bend toward the bottom wall 6 39 as a result the engagement between the locking projections 8b and the locking holes 18 and the locking pieces 19 and the locking claws 8c are released fig5 c shows a condition in which the resilient locking arm 8 fully bends in the vacant space v 39 to release the engagement with the female terminal c and then the terminal c is extracted from a rear portion of the housing when the terminal extracting block b is slightly drawn under the condition described above so as to be moved downward the state shown in 4a is again obtained which permits the terminal c to be used repeatedly fig6 to 10 show an electrical connector according to another embodiment of the present invention in this embodiment a terminal extracting block b 39 is designed so as to have a function as a terminal holder also in fig6 a housing a is the same as that of fig1 the difference between the terminal extracting block b 39 and the terminal extracting block b is only in that the terminal extracting block b 39 is formed to have a full length longer than that of the terminal extracting block.
