Abstract
Uniquely positioned slots are provided in the receptacle and uniquely positioned bosses are provided in the plug of a connector pair. These features are designed to prevent the plug from being inserted midspan and damaging the exposed contacts of the receptacle. The bosses may be located near outside corners of the plug, and may protrude sufficiently from the face of the plug to prevent the corners of the plug from being inserted into the receptacle, except when the bosses are aligned with the boss-receiving slots in the receptacle.
Claims17
A device comprising:
- a receptacle connector comprising a pair of boss-receiving slots at opposite ends of an opening and polarization slots for receiving polarization keys;
- and
- a plug that mates with the receptacle connector by insertion of an insert portion of the plug into the opening of the receptacle connector, wherein the insert portion comprises a pair of bosses at opposite ends and polarization keys that comprise respectively a pair of curved side surfaces, wherein the pair of curved side surfaces of a given polarization key has different curvatures for a proximal curved sides surface of the pair of curved side surfaces and distal curved side surface of the pair of curved side surfaces.
A device comprising:
- a receptacle connector comprising a pair of boss-receiving slots at opposite ends of an opening and polarization slots for receiving polarization keys;
- and
- a plug that mates with the receptacle connector by insertion of an insert portion of the plug into the opening of the receptacle connector, wherein the insert portion comprises a pair of bosses at opposite ends and polarization keys that comprise respectively a pair of curved side surfaces, wherein the respective pair of curved side surfaces of the polarization keys are configured to allow the polarization keys to enter corresponding polarization slots when the plug is pivoted about one of the bosses of the pair of bosses that has been inserted into a corresponding boss receiving slot of the pair of boss-receiving slots.
