DEFINITION

Classification: 439/691

Having additional resilient member cooperating with contact to increase grip on contact of mating plug:

(under subclass 682) Receptacle including a resilient means operatively associated with at least one of the contacts thereof, but not part of the contact itself, for applying pressure, over and above what the contact itself may apply, to the fingerlike counter-contact of the plug whenever the receptacle and plug are in coupled relationship so as to either help maintain the coupled relationship of the receptacle and plug or enhance the transfer of electrical current from one contact to its mating contact.
