Abstract

A connector includes a housing (10) formed with a terminal accommodation chamber (13), a terminal fitting (21) to be inserted into the terminal accommodation chamber (13) from behind the housing (10), a locking lance (14) disposed to face the terminal accommodation chamber (13), cantilevered forward and resiliently displaceable in a direction away from the terminal accommodation chamber (13) and in a direction to enter the terminal accommodation chamber (13), and a recess (20) formed in an area on a side of the locking lance (14) opposite to the terminal accommodation chamber (13).

Claims

1. A connector, comprising:

a housing (10) formed with a terminal accommodation chamber (13);

a terminal fitting (21) to be inserted into the terminal accommodation chamber (13) from behind the housing (10);

a locking lance (14) disposed to face the terminal accommodation chamber (13), cantilevered forward and resiliently displaceable in a direction away from the terminal accommodation chamber (13) and in a direction to enter the terminal accommodation chamber (13); and

a recess (20) formed in an area on a side of the locking lance (14) opposite to the terminal accommodation chamber (13).

2. The connector of claim 1, wherein the recess (20) is disposed in a rear end part of the locking lance (14).

3. The connector of claim 2, wherein an inner surface of the recess (20) includes a curved surface.

4. The connector of claim 3, wherein the housing (10) is formed by stacking two sub-housings (11, 12), in each of which the recess (20) is exposed in an outer surface, such that the recesses (20) face each other.

5. The connector of claim 4, wherein a front surface of the locking lance (14) includes:

a first locking surface (17) for locking the terminal fitting (21) from behind with the locking lance (14) resiliently displaced; and

a second locking surface (18) for locking the terminal fitting (21) from behind with a resilient displacement amount of the locking lance (14) increased when the terminal fitting (21) is displaced rearward from a locking position by the first locking surface (17).

6. The connector of claim 1, wherein an inner surface of the recess (20) includes a curved surface.

7. The connector of claim 1, wherein the housing (10) is formed by stacking two sub-housings (11, 12), in each of which the recess (20) is exposed in an outer surface, such that the recesses (20) face each other.

8. The connector of claim 1, wherein a front surface of the locking lance (14) includes:

a first locking surface (17) for locking the terminal fitting (21) from behind with the locking lance (14) resiliently displaced; and

a second locking surface (18) for locking the terminal fitting (21) from behind with a resilient displacement amount of the locking lance (14) increased when the terminal fitting (21) is displaced rearward from a locking position by the first locking surface (17).
