Electrical connector having lossy spacers

摘要

An electrical connector includes a housing stack having a first housing and a second housing stacked together with the first housing. The housing stack defines a mating end and a mounting end opposite the mating end. The housing stack defines signal contact cavities and ground contact cavities that extend continuously through the housings. At least one of the first housing and the second housing has pockets around the ground contact cavities with lossy spacers disposed therein each having a groove aligned with the corresponding ground contact cavity. Signal contacts are disposed in corresponding signal contact cavities. Ground contacts are disposed in corresponding ground contact cavities. The ground contacts are disposed in the grooves of the corresponding lossy spacers such that the ground contacts are coupled to the corresponding lossy spacers.

1. An electrical connector comprising:
a housing stack comprising a first housing and a second housing stacked together with the first housing, the housing stack defining a mating end configured for mating with a mating connector and a mounting end configured for mounting to a circuit board, the mounting end being opposite the mating end, the second housing disposed rearward of the first housing, the housing stack defining signal contact cavities and ground contact cavities that extend continuously through the first housing and the second housing between the mating end and the mounting end, at least one of the first housing and the second housing having pockets around the ground contact cavities; lossy spacers disposed in corresponding pockets, the lossy spacers each having a groove aligned with the corresponding ground contact cavity; signal contacts disposed in corresponding signal contact cavities of the housing stack and being provided at or near the mating and mounting ends for electrical connection to the mating connector and the circuit board, respectively; and ground contacts disposed in corresponding ground contact cavities of the housing stack and being provided at or near the mating and mounting ends for electrical connection to the mating connector and the circuit board, respectively, the ground contacts being disposed in the grooves of the corresponding lossy spacers such that the ground contacts are coupled to the corresponding lossy spacers.
