A connector assembly configured to electrically connect a first substrate with a second substrate is provided. The connector assembly includes an insulating support member including an array of apertures, and terminal assemblies disposed in the apertures. Each terminal assembly includes a hollow cylindrical body, and first and second terminals disposed on opposed ends of the body. The body is split by an opening extending between opposed ends, and resiliency of the body biases the first and second terminals in opposed directions along the longitudinal axis.
