System for mechanically and electrically connecting a mobile device case to different mounts

A coupling arrangement comprising:

• a projection;
• and
• a corresponding receptacle;
• wherein:
• a proximal end of the projection has a flange;
• and
• the projection includes an integral exposed first set of electrodes,
• at least a first one thereof being formed in an exposed location on the flange, and
• at least a second one thereof being formed in an exposed location on a distal end of the projection;
• wherein:
• the receptacle includes walls that define a recess having sides and a bottom, the recess being configured to removably receive the projection;
• one or more of the walls provides one or more bearing surfaces outside the recess configured to support the flange;
• and
• the receptacle includes an integral second electrode set corresponding to the first set, respectively,
• at least a first one thereof being formed in at least one exposed location on one or more of the bearing surfaces, and
• at least a second one thereof being formed in an exposed location at the bottom of the recess;
• and
• wherein the projection and the recess are correspondingly sized so that the second electrode at the distal end of the projection is disposed in contact with the second electrode at the bottom of the recess when the first electrode at the flange is disposed in contact with the first electrode at the one or more bearing surfaces.

A coupling arrangement comprising:

• a first mating part including:
• a first base;
• a projection extending from the first base;
• and
• annular groove segments formed in the base adjacent to the projection;
• a second mating part including:
• a second base into which is formed a receptacle including walls that define a recess having sides and a bottom, the recess being configured to removably receive the projection;
• and
• tabs, located adjacent to the recess and extending from the second base, and configured to removably engage the annular groove segments;
• wherein:
• a distal end of the projection includes an integral exposed first set of electrodes;
• the bottom of the receptacle includes an integral second electrode set corresponding to the first set, respectively;
• and
• the projection and the recess are correspondingly sized so that the first and second electrode sets are disposed in contact, respectively, when the distal end of the projection abuts the bottom of the recess.
