Electrical terminal connector with rotatable mounting features

An electrical system comprising:

• a conductive structure having a post extending therefrom
• an electrical connector for electrically coupling with the conductive structure, the electrical connector including:
• a terminal assembly having a conductive body terminating in a conductive tongue having an aperture for receiving the conductive structure post for coupling with the conductive structure;
• a socket assembly having a conductive body with a portion configured for receiving a conductor;
• the terminal assembly including a pin and the socket assembly including a socket portion configured for receiving the pin for mating the terminal and socket assemblies, the pin and socket portion forming a rotational interface for the terminal and socket assemblies;
• an outer groove formed on an outer surface of the terminal assembly;
• an inner groove formed in an inner surface of the socket assembly;
• an expandable ring positioned in the outer groove, the expandable ring configured for being compressed to fit inside of the outer groove for mating the terminal and socket assemblies;
• the inner groove and the outer groove positioned to align when the terminal and socket assemblies are mated for allowing the ring to decompress from the outer groove into at least part of the inner groove to secure the mated terminal and socket assemblies together in the rotational interface.
