US Patent 11289838 Connector assembly

Each of plug contacts and each of receptacle contacts come into electrical contact with each other by mating a plug connector and a receptacle connector. Each of the receptacle contacts includes a receptacle contact guide part that has a receptacle contact guide hole into which each plug contact can be inserted in a direction toward a receptacle side board, and two spring pieces that are elastically deformed when each plug contact is inserted into the receptacle contact guide hole. The two spring pieces come into contact with each plug contact inserted into the receptacle contact guide hole by a spring restoring force.
