Abstract

An electrical connector for receiving a central conductor of a coaxial cable adapter includes first and second body portions, a first electrical contact, and a coupling element. The first body portion has a first tubular portion disposed about a first axis and defines a first bore. The second body portion has a second tubular portion disposed about a second axis, which intersects the first axis, and defines a second bore. The second bore is configured to receive a coaxial adapter. The first electrical contact is secured within the first bore and has a first end within the first body portion and a second end outside of the first bore, and the first end of the first electrical contact has an opening in a side wall thereof. The coupling element is disposed in the opening in the side wall of the first electrical contact and extends in a direction of the second axis. The coupling element has a tubular wall and includes a plurality of spring members extending inward from the tubular wall such that the coupling element is configured to securely receive a central conductor of the adapter. The coupling element is configured to have a first diameter defined by the spring members in a rest position and a second diameter, greater than the first diameter, defined by an inner surface of the tubular wall of the coupling element when the spring member are urged outwardly by the central conductor of the adapter.
