The present invention is a high-power, spring-actuated connector device. The device has a male terminal and a female connector. The male terminal has a metallic tubular member that provides a contact surface for the female connector. The female connector fits inside the male terminal, when making an electrical connection. The female connector has a contact element, with a plurality of contact beams. A spring actuator is nested inside the contact element. The spring has spring arms that map, one-to-one, to the contact beams. The spring-actuator spring arms force the contact beams into electrical contact with the inner surface of the metallic tubular member of the male terminal. Thermal expansion and residual material memory create a more secure connection in this configuration.
