１３は中央に空間を有し撓み易くなつているため
に、容易に弾性変形することができる。 Assembling the terminals to the connector of this embodiment configured as above is the same as that of the conventional connector described above, so the explanation thereof will be omitted, but when the terminal fixing member 13 is press-fitted into the opening 6, As shown in FIGS. 1 and 2, the arm-shaped terminal fixing member 13 has a space in the center and is flexible, so that it can be easily elastically deformed.
従つて、保持突起１４及び開口１６には圧入に
際して過大な荷重を受けることがないために塑性
変形を生ずることがない。 Therefore, the holding protrusion 14 and the opening 16 are not subjected to an excessive load during press-fitting, so that no plastic deformation occurs.
