Abstract

An electrical connector includes a housing that is adapted to mate with a corresponding electrical connector. A connector latch is attached to the housing and is adapted to retain the housing in a mounted position on the corresponding connector. A connector position assurance is also attached to the connector latch. The connector position assurance is movable from a pre-lock position to an assurance position when the housing is attached to the corresponding connector. A block engages the connector position assurance when the connector position assurance is moved from the pre-lock position to the assurance position. The block resists movement of the connector position assurance to the assurance position.

Claims (32)

1 . An electrical connector, comprising:

a housing that is adapted to mate with a corresponding electrical connector;

a connector latch provided on the housing that is adapted to retain the housing in a mounted position on the corresponding electrical connector;

a connector position assurance supported on the housing, the connector position assurance is movable from a pre-lock position to an assurance position when the housing is attached to the corresponding electrical connector; and

a block provided on a shield positioned on the housing, wherein the block engages the connector position assurance when the connector position assurance is moved from the pre-lock position to the assurance position to resist movement of the connector position assurance to the assurance position.

2 . The electrical connector of claim 1 , wherein the connector latch is positioned between the shield and a housing seat positioned on the housing.

3 . The electrical connector of claim 1 , wherein the connector latch includes a clasp, a restricted height is defined between the clasp and the block, a portion of the connector position assurance is moved through the restricted height when the connector position assurance is moved from the pre-lock position to the assurance position, and the portion of the connector position assurance has a height that is larger than the restricted height.

4 . The electrical connector of claim 3 , wherein the connector housing includes a shield such that the connector latch is between the shield and the housing seat, and wherein the block is located on the shield.

5 . An electrical connector, comprising:

a terminal housing that is adapted to hold one or more electrical terminals;

a connector housing that includes a connector seat, wherein a portion of the terminal housing is supported on the connector seat;

a connector position assurance supported on the connector housing, the connector position assurance is movable from a pre-lock position to an assurance position when the connector housing is attached to the corresponding connector, the connector position assurance including a housing block that extends toward the connector seat to limit deflection of the connector seat.

6 . The electrical connector of claim 5 , the connector housing including a step that extends from the connector seat, wherein the step is located between a stop positioned on the connector housing and the connector seat when then the connector position assurance is in the assurance position.

7 . The electrical connector of claim 6 , wherein the step is not located between the stop and the connector seat when then the connector position assurance is in the pre-lock position.

8 . The electrical connector of claim 5 , wherein the housing block does not limit deflection of the connector seat when the connector position assurance is in the pre-lock position.

9 . The electrical connector of claim 5 , the terminal housing including one or more housing catches and the connector housing including one or more housing stops, wherein the stops deflect the connector seat away from the terminal housing when the terminal housing is inserted into the connector seat, and wherein the connector housing rebounds and each of the housing stops is engaged by a housing catch when the terminal housing is in an installed position relative to the connector housing.

10 . The electrical connector of claim 9 , the connector housing including a step that extends from the connector seat, wherein the step is located between the one or more housing stops and the connector seat when then the connector position assurance is in the assurance position.

11 . The electrical connector of claim 10 , wherein the step is not located between the one or more housing stops and the connector seat when then the connector position assurance is in the pre-lock position.

12 . An electrical connector, comprising:

a terminal housing that is adapted to hold one or more electrical terminals;

a connector housing that includes a connector seat, wherein a portion of the terminal housing is held in the connector seat;

a connector latch attached to the connector housing that is adapted to retain the connector housing in a mounted position on the corresponding connector;

a connector position assurance attached to the connector latch, the connector position assurance is movable from a pre-lock position to an assurance position when the connector housing is attached to the corresponding connector, the connector position assurance including a housing block that extends toward the connector seat to limit deflection of the connector seat; and

a block that engages the connector position assurance when the connector position assurance is moved from the pre-lock position to the assurance position to resist movement of the connector position assurance to the assurance position.

13 . The electrical connector of claim 12 , the connector housing including a shield attached to housing so that the connector latch is between the shield and the housing seat, wherein the block is located on the shield.

14 . The electrical connector of claim 12 , wherein the connector latch includes a clasp, and a restricted height is defined between the clasp and the block, wherein a portion of the connector position assurance is moved through the restricted height when the connector position assurance is moved from the pre-lock position to the assurance position and the portion of the connector position assurance is of a height that is larger than the restricted height.

15 . The electrical connector of claim 12 , the connector housing including a step that extends from the connector seat, wherein the step is located between a stop positioned on the connector housing and the connector seat when then the connector position assurance is in the assurance position.

16 . The electrical connector of claim 15 , wherein the step is not located between the stop and the connector seat when then the connector position assurance is in the pre-lock position.

17 . The electrical connector of claim 12 , wherein the housing block does not limit deflection of the connector seat when the connector position assurance is in the pre-lock position.

18 . The electrical connector of claim 12 , the terminal housing including one or more housing catches and the connector housing including one or more housing stops, wherein the housing stops deflect the connector seat away from the terminal housing when the terminal housing is inserted into the connector seat, and wherein the connector housing rebounds and each of the housing stops is engaged by a housing catch when the terminal housing is in an installed position relative to the connector housing.

19 . The electrical connector of claim 18 , the connector housing including a step that extends from the connector seat, wherein the step is located between the one or more housing stops and the connector seat when then the connector position assurance is in the assurance position.

20 . The electrical connector of claim 19 , wherein the step is not located between the one or more housing stops and the connector seat when then the connector position assurance is in the pre-lock position.
