Claim 3

The electrical connector as defined in claim 1 wherein the improvement further comprises: the generally planar surface of the connector body having a pair of laterally spaced rails which are disposed on either side of the release handle for guiding the connector position assurance device into engagement with the release handle of the lock arm.

Claim 4

The electrical connector as defined in claim 2 wherein the improvement further comprises: the pair of laterally spaced rails having inwardly facing flanges, and the connector position assurance device having a pair of laterally spaced runners which are sized to fit between the pair of rails and slide beneath the respective flanges.

Claim 5

Claim 6

In an electrical connector having a pump handle lock arm which is hinged to a connector body of the electrical connector midway between its ends to provide a forward lock arm for locking the electrical connector to a mating electrical connector and a rearward release handle which is depressible to pivot the lock arm out of engagement with a cooperating lock nib of a mating electrical connector and a connector position assurance device for assuring proper engagement of the lock arm and prevent depression of the release handle, the improvement comprising: the release handle having an upper surface and a lower surface which faces a generally planar surface of the connector body, the upper surface having a lock shoulder and the lower surface having a longitudinal groove which extends to a free end of the release handle, the generally planar surface of the connector body having a pair of laterally spaced rails which are disposed on either side of the release handle and which have inwardly facing flanges, and the connector position assurance device having a pair of laterally spaced runners which are sized to fit between the pair of rails and slide beneath the respective flanges, the connector position assurance device including a tongue which is disposed between the runners and which is sized to fit in the groove of the release handle when the lock arm Is disposed in a properly locked position, and the connector position assurance device further including a lock arm which cooperates with the lock shoulder of the release handle to lock the connector position assurance device in position.

Claim 7

In an electrical connector having a connector body which has a plurality of terminal cavities extending axially through the connector body from a forward contact end to a rearward conductor end, a plurality of terminals which are attached to insulated electrical conductors and which are disposed in the respective terminal cavities with the insulated electrical conductors extending out of the rearward conductor end of the connector body, an end bell for gathering the insulated electrical conductors into a bundle which has upper and lower clam shells which are hingedly mounted on the connector body for movement between an open position providing access to the terminal cavities and a closed position providing a gathering collar for the insulated electrical conductors, and a lock arm for locking the electrical connector to a mating electrical connector which is hinged to the connector body to provide a depressible release handle which overlies one of the clam shells when it is in the closed position, and a connector position assurance device for assuring the lock arm is properly engaged and preventing depression of the release handle, the improvement comprising: the release handle having an upper surface and a lower surface which faces a generally planar surface of the one clam shell when the one clam shell is in the closed position, the upper surface having a lock shoulder and the lower surface having a longitudinal groove which extends to a free end of the handle, the generally planar surface of the one clam shell having a pair of laterally spaced rails which are disposed on either side of the release handle and which have inwardly facing flanges, and the connector position assurance device having a pair of laterally spaced runners which are sized to fit between the pair of rails and slide beneath the respective flanges, the connector position assurance device further including a tongue which is disposed between the runners and which is sized to fit in the groove of the release handle when the lock arm is disposed in a properly locked position, and the connector position assurance device further including a lock arm which cooperates with the lock shoulder of the release handle to lock the connector position assurance device in position.

Claim 8

In an electrical connector having a connector body which has a plurality of terminal cavities extending axially through the connector body from a forward contact end to a rearward conductor end, a plurality of terminals which are attached to insulated electrical conductors and which are disposed in the respective terminal cavities with the insulated electrical conductors extending out of the rearward conductor end of the connector body, an end bell for gathering the insulated electrical conductors into a bundle which has upper and lower clam shells which are hingedly mounted on the connector body for movement between an open position providing access to the terminal cavities and a closed position providing a gathering collar for the insulated electrical conductors, and a lock arm for locking the electrical connector to a mating electrical connector which is hinged to the connector body to provide a depressible release handle which overlies one of the clam shells when it is in the closed position, and a connector position assurance device for assuring the lock arm is properly engaged and preventing depression of the release handle, the improvement comprising: the release handle having an upper surface and a lower surface which faces a generally planar surface of the one clam shell when the one clam shell is in the closed position, the upper surface having a lock shoulder and the lower surface having a longitudinal groove which extends to a free end of the handle, the generally planar surface of the one clam shell having a pair of laterally spaced rails which are disposed on either side of the release handle and which have inwardly facing flanges, and the connector position assurance device having a pair of laterally spaced runners which are sized to fit between the pair of rails and slide beneath the respective flanges, the connector position assurance device further including a tongue which is disposed between the runners and which is sized to fit in the groove of the release handle when the lock arm is disposed in a properly locked position, and the connector position assurance device further including a lock arm which cooperates with the lock shoulder of the release handle to lock the connector position assurance device in position.
