Abstract: An electrical connector includes a housing, contacts, ground shields, and a ground frame. The housing extends between a front end and an opposite rear end. The front end is configured to be mated with a mating connector. The contacts and ground shields are held by the housing. The ground shields at least partially surround the contacts to provide electrical shielding for the contacts. The ground frame has a first side coupled to the rear end of the housing and a second side facing the circuit board. The contacts have terminating ends and the ground shields have mounting ends. The terminating ends and the mounting ends extend from the rear end of the housing through the ground frame for termination to the circuit board. The ground frame engages the ground shields to electrically join the ground shields.

Abstract: A mezzanine connector assembly includes a mezzanine receptacle connector having a plurality of receptacle contacts arranged in pairs for carrying differential pair signals and each having a mating interface. The mezzanine receptacle connector has a plurality of receptacle ground shields surrounding each pair of receptacle contacts and providing electrical shielding from each other pair. The mezzanine connector assembly includes a mezzanine header connector having a plurality of header contacts arranged in pairs. Each header contact has a mating segment mated to the mating interface of the corresponding receptacle contact. The mezzanine header connector has a plurality of header ground shields surrounding each pair of header contacts and providing electrical shielding from each other pair of header contacts. The header ground shields are mechanically and electrically connected to associated receptacle ground shields to create shield boxes around the various mated pairs of header and receptacle contacts.

Abstract: A header assembly of a mezzanine connector system may include a main housing defining signal channels extending through the main housing and ground channels extending into a first surface of the main housing, a plurality of signal modules, and a plurality of ground shields. At least a portion of each of the plurality of signal modules is retained within a respective one of the signal channels. At least a portion of each of the plurality of ground shields is retained within at least one of the ground channels.

Abstract: A connector system includes a first connector comprising a housing holding a plurality of contacts, a second connector comprising a housing holding a plurality of contacts, and a metal shield having walls defining a shielded chamber. The first and second connectors are configured to be mounted to a circuit board in a stacked arrangement next to one another. The first and second connectors are configured to be arranged in a shielded configuration in which the first and second connectors are positioned within the shielded chamber and mounted to the circuit board with the metal shield. The first and second connectors are also configured to be arranged in an unshielded configuration in which the first and second connectors are mounted to the circuit board without the metal shield.
