Reversible USB connector with compliant member to spread stress and increase contact normal force

摘要

Embodiments can provide reversible or dual orientation USB plug connectors for mating with standard USB receptacle connectors, e.g., a standard Type A USB receptacle connector. Accordingly, the present invention may be compatible with any current or future electronic device that includes a standard USB receptacle connector. USB plug connectors according to the present invention can have a 180 degree symmetrical, double orientation design, which enables the plug connector to be inserted into a corresponding receptacle connector in either of two intuitive orientations. Thus, embodiments of the present invention may reduce the potential for USB connector damage and user frustration during the incorrect insertion of a USB plug connector into a corresponding USB receptacle connector of an electronic device. Reversible USB plug connectors according to the present invention may include a compliant member or structural support for distributing stress and increasing contact normal force at the tongue of the reversible USB plug connector.

主权项

1. A reversible plug connector comprising:
a body; a dielectric base; a shell extending from the body and having an opening at a first end that communicates with a cavity defined by inner surfaces of the shell and the dielectric base; a deflectable tongue disposed within the cavity and extending from the dielectric base towards the opening, the tongue having a tip proximal the opening and first and second opposing surfaces that extend from the tip towards the base, the tongue including a first plurality of contacts exposed at the first opposing surface of the tongue proximal the tip and a second plurality of contacts exposed at the second opposing surface of the tongue proximal the tip; and a support structure that includes first and second support members disposed adjacent to the base and located on opposite sides of the tongue, the first support member having a first major surface that faces the first opposing surface of the tongue, the second support member having a second major surface that faces the second opposing surface of the tongue, the second support member defining a curved recess.
