Connector and connector assembly

A connector, comprising:

• a housing (10) with at least one cavity (1 1) and a deformation space (21) substantially adjacent the cavity (11);
• at least one terminal fitting (30) insertable into the cavity (11);
• at least one resiliently deformable lock (15) extending substantially along an inner wall of the cavity (11), the lock (15) being deformed towards the deformation space (21) due to interference with the terminal fitting (30) as the terminal fitting (30) is inserted into the cavity (11), the lock (15) being restored resiliently to engage the terminal fitting (30) and to retain the terminal fitting (30) when the terminal fitting (30) is inserted properly;
• and
• a jig insertion opening (52) being formed in a front wall of the housing (10) for receiving a jig (J) for disengaging the lock (15) from the terminal fitting (30), an area of the edge of the jig insertion opening (52) corresponding to the deformation space (21) being formed by an opening forming member (40′) separate from the housing (10) and displaceable relative to the housing (10) in a direction as to widen the jig insertion opening (52).

A connector assembly, comprising:

• at least one terminal fitting (107) with a terminal connecting portion (109) for connection with a mating terminal fitting (108) and a wire connection portion (110) behind the terminal connecting portion (109) for connection with a wire and being cross-sectionally larger height from a lateral surface than the terminal connecting portion (109),
• a first housing (101) for accommodating the terminal fitting (107),
• a bulge (111) formed at the outer surfaces of the first housing (101) at a part for accommodating the wire connection portion (110), and bulging out from a part of the first housing (107) for accommodating the terminal connecting portion (109) via a an enlarging portion (111A), and
• a second housing (108) including a receptacle (126) for receiving the first housing (107),
• wherein an escaping portion (142) is formed at an opening edge (126OE) of the receptacle (126) of the second housing (108) for receiving the bulge (111) when the two housings (107,108) are connected.

A connector, comprising:

• a housing (10;
• 101) with at least one cavity (11;
• 106) for receiving at least one terminal fitting (30;
• 107),
• at least one lock (15;
• 112) at least partly exposed at a side surface of the housing (10;
• 101) and engageable with the terminal fitting (30;
• 107) while being resiliently deformed outward of the side surface of the housing (10;
• 101), and
• a retainer (40;
• 40′;
• 115) mountable to the housing (10;
• 101) and being movable between a first position (1P) where the terminal fitting (30;
• 117) is insertable into and withdrawable from the cavity (11;
• 106) and a second position (2P) where the retainer (40;
• 40′;
• 115) engages and retains the terminal fitting (30;
• 107), the retainer (40;
• 40′;
• 115) including a terminal lock (45;
• 120) for locking the terminal fitting (30;
• 107) and an excessive deformation preventing portion (41;
• 116) at a resiliently deforming side of the lock (15;
• 112) for preventing excessive deformation of the lock (15;
• 112) when the retainer (40;
• 40′;
• 115) is at the first position (1P).
