Connector assembly

A receptacle connector, comprising:

• a receptacle housing having a first curved wall portion, a second curved wall portion, a first side wall portion, and a second side wall portion that at least partially define a cavity having an open end, the first curved wall portion and the second curved wall portion spaced in a height direction of the receptacle housing, and the first side wall portion and the second side wall portion spaced in a width direction of the receptacle housing;
• and
• pin contacts located along the first curved wall portion of the receptacle housing and spaced from each other in the width direction of the receptacle housing,
• wherein the pin contacts include a first group of two or more contacts at a first angular orientation relative to the receptacle housing, a second group of two or more contacts at a second angular orientation relative to the receptacle housing, and a third group of two or more contacts at a third angular orientation relative to the receptacle housing, wherein the first angular orientation, the second angular orientation, and the third angular orientation are different from each other.

A receptacle connector, comprising:

• a receptacle housing having a convex wall portion and a concave wall portion that at least partially define a cavity having an open end;
• first pin contacts spaced along the convex wall portion of the receptacle housing and each configured to deflect along a respective line of action that is normal to a convex curvature of the convex wall portion at each of the first pin contacts;
• and
• second pin contacts spaced along the concave wall portion of the receptacle housing and each configured to deflect along a respective line of action that is normal to a concave curvature of the concave wall portion at each of the second pin contacts.

A plug connector, comprising:

• a connector body having a convex wall portion and a concave wall portion;
• first contact pads spaced along the convex wall portion of the connector body;
• and
• second contact pads spaced along the concave wall portion of the connector body.

A headband, comprising:

• a first plug connector having a first convex wall portion, a first concave wall portion, and first connector pads that are located on at least one of the first convex wall portion or the first concave wall portion;
• a second plug connector having a second convex wall portion, a second concave wall portion, and second connector pads that are located on at least one of the second convex wall portion or the second concave wall portion;
• and
• an intermediate portion that extends between the first plug connector and the second plug connector.
