Universal serial bus plug and receptacle coupling arrangements

A plug configured for mating with a socket-equipped arrangement (SEA), the plug comprising:

• a plurality of plug pins;
• and
• a plug housing surrounding the plurality of plug pins, at least one surface of the plug housing having therein an aperture,
• wherein the plug housing is configured to bias a spring-loaded mechanism included in a plug-receiving cavity of the SEA when the plug is inserted into the plug-receiving cavity, and wherein the aperture is configured to mate with the spring-loaded mechanism when the plug is in a terminal mating position with the plug-receiving cavity.

A Universal Serial Bus (USB) plug configured for mating with a USB socket-equipped arrangement (USB-SEA), the USB plug comprising:

• a plurality of plug pins;
• and
• a metal plug housing surrounding the plurality of plug pins, a first side of the metal plug housing having a first aperture, a second side of the metal plug housing having a second aperture,
• wherein the metal plug housing is configured to bias a first spring-loaded mechanism and a second spring-loaded mechanism included in a plug-receiving cavity of the SEA when the plug is inserted into the plug-receiving cavity, wherein the first aperture is configured to mate with the first spring-loaded mechanism when the plug is in a terminal mating position with the plug-receiving cavity, and wherein the second aperture is configured to mate with the second spring-loaded mechanism when the plug is in the terminal mating position.
