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 is configured to define a first bore extending in a first axial direction, and the second body portion is configured to define a second bore extending in a second axial direction, the second axial direction being angled relative to the first axial direction. The electrical contact is configured to be disposed in the first body portion, and the conductive coupling element in contact with the electrical contact. The second body portion is configured to receive a coaxial cable adapter, and the conductive coupling element is configured to receive a central conductor of the adapter, and the coupling element includes a wall having a first portion with a first inner diameter and a second portion with a second inner diameter, the second inner diameter being smaller that the first inner diameter. The conductive coupling element includes a plurality of spring fingers that, in a rest position, extend radially inward from the first portion of the coupling element to define an opening having a diameter that is smaller than the second inner diameter such that the coupling element is configured to receive the central conductor having a diameter equal to or less than the second diameter and provide an electrical connection between the electrical contact and the central conductor.
