Patent attributes
A communication system includes first and second circuit card assemblies each having a PCB and an electrical connector having a mating end and contacts. The first electrical connector has a receptacle housing and a mating housing received in the receptacle housing with cam levers therebetween. The second electrical connector has a header housing and driving elements interfacing with the cam levers to actuate the mating housing relative to the receptacle housing. The PCB includes a slot receiving the other PCB in a board loading direction and the header housing is coupled to the receptacle housing in the board loading direction to interface the driving elements with the cam levers. The mating housing is movable away from the second mating end to a preloaded position by the driving elements and is movable toward the second mating end to a mated position by the driving elements.
