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 modular connector assembly includes a housing having a mating end and a mounting end opposite the mating end. The mating end is configured to be mated with a header connector and the mounting end is configured to be mounted to a circuit board. The housing has a plurality of individual chambers separated by chamber walls. Contact assemblies are received in corresponding chambers. Each contact assembly has a dielectric body holding a differential pair of receptacle signal contacts configured to be terminated to the circuit board and mated with corresponding header signal contacts of the header connector. Each contact assembly has a ground shield coupled to an exterior of the dielectric body providing electrical shielding for the differential pair of receptacle signal contacts from other pairs of receptacle signal contacts.
Abstract:
An electrical connector includes a housing stack comprising a front housing and a rear housing coupled to the front housing at a seam. The housing stack defines plural contact cavities that extend continuously through the front housing and the rear housing between mating and mounting ends. A lossy spacer is disposed at the seam between the front and rear housings. The lossy spacer has plural contact cavities aligned with corresponding contact cavities of the housing stack. Signal and ground contacts are disposed in corresponding contact cavities of the housing stack. The signal contacts extend through the lossy spacer such that the signal contacts do not directly engage the lossy spacer. The ground contacts extend through the contact cavities in the lossy spacer such that the ground contacts are coupled by the lossy spacer.
Abstract:
An electrical connector includes a housing stack and plural conductors. The housing stack includes a front housing and a rear housing. The rear housing is disposed rearward of the front housing. The housing stack defines plural cavities that extend continuously through the front housing and the rear housing. The front housing includes a forward-facing shoulder within at least some of the cavities. The rear housing includes a rear-facing shoulder associated with the cavities that include the forward-facing shoulder. The conductors are disposed in the cavities of the housing stack. At least some of the conductors have a first projecting feature that engages the forward-facing shoulder in the corresponding cavity and a second projecting feature that engages the rear-facing shoulder to secure the front housing to the rear housing.
Abstract:
An electrical connector includes a front housing and a plurality of contact modules stacked side by side along a rear side of the front housing. Each contact module comprises a housing frame, multiple signal conductors and ground conductors held in the housing frame, and a ground shield coupled to an outer side of the housing frame. The housing frame is formed by a first shell member abutting a second shell member at an interface. At least one of the shell members defines multiple openings that align with the ground conductors held in the housing frame. The ground shield includes ground tabs that extend through the openings and engage the ground conductors to electrically connect the ground shield and the ground conductors. Broad sides of the signal conductors and the ground conductors are oriented orthogonal to the interface between the first and second shell members.

Abstract:
A leadframe for a contact module includes signal contacts arranged in pairs carrying differential signals. Each pair of signal contacts includes a first signal contact and a second signal contact. Each signal contact has a mating beam at an end thereof configured to be electrically connected to a corresponding header contact of a header assembly. Each mating beam includes a stem and a branch extending from the stem. A first paddle extends from the stem and a second paddle extends from the branch. In an initial, stamped orientation, the mating beams are stamped such that the mating beams of the first and second signal contacts within the same pair of signal contacts are angled non-parallel to one another.
Abstract:
A header transition connector includes a header housing having a first end and a second end with a separating wall separating a first cavity from a second cavity. The separating wall has signal contact openings and ground shield openings therethrough. Header signal contacts are held in corresponding signal contact openings and arranged in pairs carrying differential signals. The header signal contacts have first mating ends in the first cavity and second mating ends in the second cavity for mating with first and second receptacle connectors, respectively. Header ground shields are held in corresponding ground shield openings and have walls surrounding associated pairs of header signal contacts on at least two sides thereof. The header ground shields have first mating ends in the first cavity and second mating ends in the second cavity for mating with the first and second receptacle connectors, respectively.
