Sealed connector with an extended seal sleeve and an anti-water pooling retainer
An connector includes a terminated cable, a connector body defining a cylindrical terminal cavity configured to receive the terminated cable, and a cable seal axially surrounding a portion of the terminated cable. The cable seal defines a compliant primary sealing ring that is in compressive contact with an inner wall of the terminal cavity. The cable seal further defines an extended sleeve. The connector also includes a seal retainer that is inserted within a distal end of the terminal cavity and axially surrounds at least a portion of the extended sleeve. An inner surface of the seal retainer is proximate at least a portion of the extended sleeve and an outer surface of the seal retainer is proximate the inner wall of the terminal cavity.
1. A connector, comprising:
a terminated cable;
a connector body defining a terminal cavity configured to receive the terminated cable;
a cable seal axially surrounding a portion of the terminated cable, said cable seal defining a compliant primary sealing ring in compressive contact with an inner wall of the terminal cavity, said cable seal further defining an extended sleeve; and
a seal retainer inserted within a distal end of the terminal cavity and axially surrounding at least a portion of the extended sleeve, wherein a side wall of the seal retainer is longitudinally split allowing the seal retainer to be laterally placed onto the terminated cable and wherein an inner surface of the seal retainer is proximate the at least a portion of the extended sleeve and an outer surface of the seal retainer is proximate the inner wall of the terminal cavity, wherein the side wall defines a tongue on one side of the split and a groove on the other side of the split configured to receive the tongue, wherein the tongue and groove cooperate to stabilize the side wall when the split portion is joined.
2. The connector in accordance with claim 1 , wherein the extended sleeve defines a compliant secondary sealing ring in compressive contact with the inner surface of the seal retainer.
3. The connector in accordance with claim 1 , wherein the retainer substantially fills the volume of the space within the terminal cavity from the cable seal to the distal end of the terminal cavity.
4. The connector in accordance with claim 1 , wherein the retainer provides cable motion strain relief and maintains compression between the cable seal and the cavity inner wall.
5. The connector in accordance with claim 1 , wherein a distal end of the seal retainer defines a flange having an outside diameter larger than an inside diameter of the terminal cavity.
6. The connector in accordance with claim 5 , wherein the flange of the seal retainer is also split and wherein a portion of the flange opposite the split defines a gap allowing the seal retainer to flex as it is laterally placed over the terminated cable.
7. A connector, comprising:
a terminated cable;
a connector body defining a terminal cavity configured to receive the terminated cable;
a cable seal axially surrounding a portion of the terminated cable, said cable seal defining a compliant primary sealing ring in compressive contact with an inner wall of the terminal cavity, said cable seal further defining an extended sleeve; and
a seal retainer inserted within a distal end of the terminal cavity and axially surrounding at least a portion of the extended sleeve, wherein a side wall of the seal retainer is longitudinally split allowing the seal retainer to be laterally placed onto the terminated cable and wherein an inner surface of the seal retainer is proximate the at least a portion of the extended sleeve and an outer surface of the seal retainer is proximate the inner wall of the terminal cavity, wherein the seal retainer defines a locking nib on a resilient cantilever beam that is configured to engage an indentation in the inner wall of the terminal cavity, thereby retaining the seal retainer within the terminal cavity.
8. The connector in accordance with claim 7 , wherein the connector body defines a cylindrical terminal tower containing the terminal cavity and wherein the flange cooperates with a distal end of the terminal tower to locate the locking nib and indentation relative to one another.
9. The connector in accordance with claim 7 , wherein the extended sleeve defines a compliant secondary sealing ring in compressive contact with the inner surface of the seal retainer.
10. The connector in accordance with claim 7 , wherein the retainer substantially fills the volume of the space within the terminal cavity from the cable seal to the distal end of the terminal cavity.
11. The connector in accordance with claim 7 , wherein the retainer provides cable motion strain relief and maintains compression between the cable seal and the cavity inner wall.
12. The connector in accordance with claim 7 , wherein a distal end of the seal retainer defines a flange having an outside diameter larger than an inside diameter of the terminal cavity.
13. The connector in accordance with claim 12 , wherein the flange of the seal retainer is also split and wherein a portion of the flange opposite the split defines a gap allowing the seal retainer to flex as it is laterally placed over the terminated cable.
