First Claim
1. A sealed electrical connector assembly, said assembly comprising:
- a connector position assurance device (CPA) including at least one CPA support rail and a CPA latch finger;
a plug housing having a body section with a mating interface on one end thereof, said mating interface retaining a plurality of plug contacts, said plug housing further including a shroud extending about at least a portion of said body section, said shroud being spaced apart from said body section by a gap, said mating interface extending outwardly from and beyond said shroud;
a header having a base retaining a plurality of header contacts adapted to electrically engage said plug contacts, said header having walls defining a plug receptacle adapted for receiving said mating interface, said walls being received in said gap between said shroud and said body section;
a seal mounted to one of said plug housing and header, said seal forming a hermetic seal between said plug housing and header when said plug housing and header are fully mated with one another; and
a CPA retention assembly mounted to at least one of said plug housing and said header, said CPA being slidably mounted to said CPA retention assembly and movable between a retracted position and a locked position, said CPA permitting engagement and disengagement of said header and plug housing when in said retracted position, said CPA preventing engagement and disengagement of said header and plug housing when in said locked position.

Abstract
A sealed electrical connector assembly is provided having a connector position assurance device (CPA) including at least one CPA support rail and a CPA latch finger. A plug housing is provided with a body section having a mating interface on one end thereof that retains a plurality of plug contacts. The plug housing includes a shroud extending about at least a portion of the body section and is spaced apart from the body section by a predefined gap. A header is provided having a base retaining a plurality of header contacts adapted to electrically engage the plug contacts. The header includes walls defining a plug receptacle adapted for receiving the mating interface. The walls are received in the gap between the shroud and the body section of the plug housing. A seal is mounted to one of the plug housing end header to form a hermetic seal between the plug housing and header when fully mated with one another. A CPA retention assembly is mounted to at least one of the plug housing and header. The CPA is slidably mounted to the CPA retention assembly and moveable between a retracted position and a locked position. The CPA permits engagement and disengagement of the header and plug when in the CPA retracted position and prevents engagement and disengagement of the header plug assembly when in the CPA locked position.

16. An electrical connector comprising:
-
a connector position assurance device (CPA) having a CPA guideway and a CPA retention lever;
a first connector housing having a first connector interface containing at least one contact;
a second connector housing having a second connector interface containing at least one contact, said contacts of said first and second connector interfaces being mated with one another;
a shroud mounted to said first connector housing and arranged to surround said second connector housing when said first and second connector housings are fully mated, said first connector interface extending outwardly from and beyond said shroud, said first connector interface being received within said second connector housing when said first and second connector housings are fully mated;

24. A sealed electrical connector housing assembly, said assembly comprising:
-
a connector position assurance device (CPA);
a first housing having a shroud, said first housing defining a mating interface extending outwardly from and beyond said shroud;
a second housing defining an opening receiving said mating interface of said first housing;
a latch located on one of said first or second housings;
a latch mating element, on another of said first and second housings, positioned to securely engage said latch when said first and second housings are fully mated with one another;
a seal mounted on one of the first and second housings wherein said CPA is slidably mounted to one of said first and second housings to be movable between a retracted position and a locked position, said assembly being configured such that when said first and second housings are attempted to be mated with said CPA in said locked position, said CPA will be forced back to said retracted position. - View Dependent Claims (25, 26, 27, 28, 29)
