Electric connector with connector position assurance

1. An electric connector comprising:

a connector housing including a latch that is movable between an opened position and a closed position; and

a connector position assurance supported on the connector housing for rotational movement relative to the connector housing between a locked position and an unlocked position such that when the connector position assurance is in the locked position, the latch is prevented from moving from the closed position to the opened position, and

wherein the connector position assurance includes an assurance catch that is located in a circumferential catch slot on the connector housing, and the assurance catch is located on a resilient bridge on the connector position assurance.

2. The electric connector of claim 1 , wherein when the latch is in the opened position, the connector position assurance is prevented from moving from the unlocked position to the locked position.

3. An electric connector assembly comprising:

a first electric connector including a first connector housing having a latch that is movable between an opened position and a closed position;

a second electric connector movable relative to the first electric connector between an initial position and a mated position, the second electric connector including a second connector housing having a connector catch that is engaged by the latch to retain the second electric connector in the mated position when the latch is in the closed position; and

a connector position assurance supported on the first connector housing for rotational movement relative to the first connector housing between a locked position and an unlocked position such that when the connector position assurance is in the locked position, the latch is prevented from moving from the closed position to the opened position,

wherein the connector position assurance includes an assurance catch that is located in a circumferential catch slot on the first connector housing.

4. The electric connector assembly of claim 3 , wherein when the latch is in the opened position, the connector position assurance is prevented from moving from the unlocked position to the locked position.

5. The electric connector assembly of claim 3 , wherein the assurance catch is located on a resilient bridge on the connector position assurance.

6. The electric connector assembly of claim 3 , wherein the first connector housing includes a lock channel that extends from a mate end of the first connector housing through the catch slot and an unlock channel that extends from the mate end of the first connector housing through the catch slot.

7. The electric connector assembly of claim 6 , wherein when the connector position assurance in the locked position, the assurance catch is located in the lock channel, and wherein when the connector position assurance in the unlocked position, the assurance catch is located in the unlock channel.

8. The electric connector assembly of claim 7 , wherein the second connector housing includes an unlock stop that is located in the unlock channel when the second electric connector in the mated position and a lock stop that is located in the lock channel when the second electric connector in the mated position.

9. The electric connector assembly of claim 8 , wherein when the connector position assurance is in the unlocked position and the second electric connector is moved from the mated position toward the initial position, the assurance catch engages the unlock stop to prevent movement of the second electric connector relative to the first electric connector at an interlock open position.

10. The electric connector assembly of claim 9 , wherein when the connector position assurance is in the locked position and the second electric connector is moved from the mated position toward the initial position, the assurance catch engages the lock stop to prevent movement of the second electric connector relative to the first electric connector.

11. The electric connector assembly of claim 9 , wherein when the connector position assurance is in the unlocked position and the second electric connector is moved from the initial position toward the mated position, the assurance catch engages the unlock stop and biases the unlock stop out of the unlock channel.

12. An electric connector comprising:

a connector housing including a latch that is movable between an opened position and a closed position; and

a connector position assurance supported on the connector housing for rotational movement relative to the connector housing between a locked position and an unlocked position such that when the connector position assurance is in the locked position, the latch is prevented from moving from the closed position to the opened position, and

wherein the connector position assurance includes an assurance catch that is located in a circumferential catch slot on the connector housing, and the connector housing includes a lock channel that extends from a mate end of the connector housing through the catch slot and an unlock channel that extends from the mate end of the connector housing through the catch slot.

13. The electric connector of claim 12 , wherein when the latch is in the opened position, the connector position assurance is prevented from moving from the unlocked position to the locked position.

14. An electric connector comprising:

a connector housing including a latch that is movable between an opened position and a closed position; and

a connector position assurance supported on the connector housing for rotational movement relative to the connector housing between a locked position and an unlocked position such that when the connector position assurance is in the locked position, the latch is prevented from moving from the closed position to the opened position, and

wherein a shielded cable is attached to the connector housing, an electromagnetic shield is supported in the connector housing and electrically connected to a shield layer of the shielded cable, a cable seal is supported on an inner surface of the electromagnetic shield, and a housing seal is supported on an outer surface of the electromagnetic shield.

15. The electric connector of claim 14 , wherein when the latch is in the opened position, the connector position assurance is prevented from moving from the unlocked position to the locked position.
