An LED (light emitting diode) panel. In particular, an LED panel that is part of a modular system used to construct a wall mounted LED video screen. An LED panel includes a chassis and an LED tile including a plurality of surface mount devices attached thereto. The LED tile is removably mounted to a front of the chassis, and further includes: a first power connector and a first data connector; and a connector assembly mounted on the chassis. The connector assembly includes a support board; a second power connector; a second data connector; and a biasing member arranged to urge the support board in a direction towards the front of the chassis, such that the second power connector and second data connector engage with the first power connector and first data connector, respectively.

A coaxial connector assembly has a housing with at least one contact receiving cavity which extends from a mating end to a contact assembly receiving end. The contact receiving cavity has a mounting section proximate the contact assembly receiving end. A contact assembly is positioned in the contact receiving cavity. The contact assembly has a front flange proximate a mating portion of the contact assembly. A positioning member is inserted on the mating portion of the contact assembly. The positioning member cooperates with the flange to position the positioning member on the mating portion of the contact assembly. The positioning member cooperates with a wall of the contact receiving cavity to limit the movement of the mating portion of the contact assembly in a direction which is transverse to a longitudinal axis of the contact assembly.
