And lances (100a, 100b) for locking the terminals, Side walls (96a, 96b) that define the terminal accommodating chambers are disposed to face each other across a side wall (S) that defines the adjacent terminal accommodating chambers, Each of the two side walls arranged opposite to each other includes an arm (106a, 106b) that is elastically deformable in a rising direction of the side wall as a part of the side wall, The arms are connected by a connecting portion (110), The lance is supported by the arm which is a part of the side wall of the terminal accommodating chamber provided with the lance.
- Terminal locking structure (2) Slits (104a, 104b) extending from the rear end toward the front side are formed on the two oppositely arranged side walls, The arm is a part of the side wall located in a direction in which the side wall rises from the slit.
- (3) Ribs (112a, 112b) projecting from the arm toward the lance and extending forward are connected to each of the two side walls arranged opposite to each other, The lance is supported by the arm via the rib, The terminal locking structure according to the above (1) or (2).
- the two opposingly arranged side walls are connected by a bottom plate (108) that defines the space together with the side walls, and the connecting portion positioned to face the bottom plate, The surface of the connecting portion that faces the bottom plate is formed such that the tip of an unlocking jig (114) inserted into the space can contact.
- the terminal locking structure according to any one of (1) to (3) above.
- the work of pulling out the terminal from the terminal accommodating chamber can be shortened.
- the present invention exhibiting this effect is useful for a terminal locking structure accommodated in a connector housing and a connector having the locking structure.
