An electrical connector assembly includes an electrical connector and a metal shielding shell. The electrical connector includes an insulating body and a number of conductive terminals. The insulating body includes a slot. Each conductive terminal includes an elastic abutting portion for abutting against the circuit board. The metal shielding shell includes a receiving cavity for receiving a mating connector. When the mating connector is inserted into the receiving cavity and has not yet made contact with the conductive terminals of the electrical connector, a better shielding effect can be achieved. Besides, by electrically connecting the conductive terminals and the circuit board in a mutually abutting manner, the requirement on the complexity of the circuit board manufacturing process is reduced.

A connector assembly is disclosed to include a shielding cage and a receptacle connector. The shielding cage forms at least one insertion space and a front end port communicatively coupled to the insertion space, the insertion space is defined by a top wall, a bottom wall and two side walls which cooperate with each other. The receptacle connector is provided to a rear segment of the shielding cage and includes a receptacle housing. The shielding cage further includes at least one stopping piece and at least one support stopping block which extend into the insertion space, the support stopping block is interposed between the stopping piece and the receptacle housing and supports the stopping piece. In another manner, the shielding cage may include a withdrawing stop portion and a rear stopping piece, the withdrawing stop portion is used to limit the receptacle housing to displace rearwardly, the rear stopping piece is used to stop the receptacle housing from behind the receptacle housing.

An optical port shielding and fastening apparatus is configured to be installed in the optical module. The optical module includes a housing assembly and an optical component located in the housing assembly.
