Waterproof connector kit useful for airfield lighting applications
A waterproof electrical connector for airfield lighting applications has a connector body with a first end and an opposing second end. The first end terminates at a first end cap that has a strain/bend relief feature and a first bore for receiving a cable that extends into the first end. At least one O-Ring extends from the walls of the first bore. The opposing second end terminates at a second end cap and has a second bore extending through the second end cap and into the second end. A sleeve is affixed to an exterior surface of the second end cap. An electrically insulated cable is inserted into the first bore engaging the O-Rings to form a waterproof seal. An electrical contact engages the second end cap and the sleeve folds over the second end cap to engage a surface of this contact forming a waterproof seal.
1. An electrical connector, comprising:
a connector body having a first end and an opposing second end thereof;
said first end adapted to receive a first electrically insulated cable terminating at a first molded plastic end cap, said first molded plastic end cap having a maximum thickness adjacent said first end of said connector body and also having a through bore with a diameter greater than a diameter of said first electrically insulated cable;
said second end adapted to receive a second electrically insulated cable, wherein said second end terminates at a second molded plastic end cap formed from an electrically insulating material and having a first end portion bonded to said connector body and a second end portion extending beyond said connector body; and
a sleeve affixed to an exterior surface of said second end formed from an electrically insulating material and extending beyond said second end portion.
2. The electrical connector of claim 1 wherein said first end cap includes at least one O-ring for engaging said first electrically insulated cable proximate said first end of said connector body.
3. The electrical connector of claim 2 wherein said first end cap includes a molded bend/strain relief effective to absorb strain from cable bending and reduce stretching or opening at the back of the connector, which can create a water entry point and position the cable appropriately as the cable enters the back of the connector.
4. The electrical connector of claim 3 wherein the O-Rings are designed to make positive contact on a primary cable jacket to prevent water entry.
5. The electrical connector of claim 4 wherein the O-Rings remove debris from the primary cable jacket upon insertion and clean away excess particles to reduce the occurrence of future voids in the connection caused by foreign particles.
6. The electrical connector of claim 2 wherein said sleeve is designed to be installed and uninstalled over and over again without losing its properties and positive connection to a ridge of a primary connector of the transformer.
7. The electrical connector of claim 6 wherein the sleeve provides additional strength and support to keep the connection together as the cable is pulled and placed to prevent the connection from coming unplugged.
8. The electrical connector of claim 1 wherein the connector is a component of a kit that is completely serviceable and can be used over and over again.
9. The electrical connector of claim 1 wherein a chemical weld is disposed between said connector body and said first molded plastic end cap.
10. The electrical connector of claim 9 wherein said connector body is formed from a thermoplastic vulcanizate.
11. The electrical connector of claim 10 wherein said molded bend/strain relief includes a plurality of indentations in a circumferential exterior portion of said first end cap.
12. The electrical connector of claim 11 wherein a chemical weld is disposed between said connector body and said first molded plastic end cap.
13. The electrical connector of claim 1 wherein said molded bend/strain relief includes a plurality of indentations in a circumferential exterior portion of said first end cap.
14. The electrical connector of claim 13 wherein a chemical weld is disposed between said connector body and said first molded plastic end cap.
