International Classification:

H01R 13648

US Classification:

439608

Abstract:

A high-density connector utilizes a plurality of terminal assemblies that are assembled together into a block, or single unit, to form a connector. Each terminal assembly of the connector utilizes a plurality of conductive terminals having contact portions for mating with an opposing connector, and body portions held within an insulative body portion of the assembly. The terminal assemblies support arrays of terminals arranged in a specific order of signal-ground-signal arrays. The terminal assemblies have at least two insulative housing portions that support the signal terminal arrays and an intervening ground terminal array, which may or may not be supported by an associated insulative housing. The ground members have a series of grounding tabs formed therewith with extend out from the plane of the ground members, on opposite sides thereof into contact with ground reference terminals of the signal terminal arrays. In this manner, a ground path is enabled between the signal terminal and ground terminal arrays.

International Classification:

US Classification:

439637, 439608, 439108

Abstract:

A differential signal connector that is used for edge card application has a plurality of differential signal terminals and associated ground terminals arranged in âtripletsâ, i. e. , distinct sets of three conductive terminals, each such triplet including a pair of differential signal terminals and one associated ground terminal. The ground terminal is flanked by the two differential signal terminals and each triplet is spaced apart from an adjacent triplet by a spacing which is greater than any single spacing between adjacent terminals within a triplet. Circuit boards to which such a connector is mounted are also disclosed and they have a particular pattern of termination traces, commonly taking the form of plated vias extending through the circuit board. These vias are arranged in a triangular pattern and the ground reference plane of the circuit board is provided with voids, one void being associated and encompassing a pair of the differential signal vias of a single terminal triplet. This reduces the capacitance of the signal vias and thereby increases the impedance of the circuit board within the launch area to lessen impedance discontinuities in the connector-circuit board interface.

International Classification:

H10R 13648

US Classification:

439608

Abstract:

A high-density connector utilizes a plurality of terminal assemblies that are assembled together into a block, or single unit, to form a connector. Each terminal assembly of the connector utilizes a plurality of conductive terminals having contact portions for mating with an opposing connector, tail portions for mounting to a circuit substrate and body portions held within an insulative body portion of the assembly. The body portions are supported within a housing in the form of a wafer which is plated with a conductive material so as to provide an all encompassing ground structure that surrounds the terminals and their insulative supporting terminal assemblies. In this manner a reference ground is provided around each signal terminal between its contact and tail portions that emulates a coaxial cable. The tails of the terminals and the ground structure have wide body portions with narrow contact portions to promote wicking of solder onto the tails for establishing a reliable solder mounting of the connector to a circuit board.

US Classification:

439608, 439246, 439439, 439625

Abstract:

A connector assembly is suitable for connecting circuit boards together. The connector assembly includes a series of ground and signal terminal sets assembled in composite wafers that may be held within a housing. The ground terminals include pairs of flat contact blades that are aligned together in abutting contact to form a column of ground contacts blades of double width, and the signal terminals are arranged in sets on opposite sides of the ground terminal blades and the signal terminals have general L-shapes that are arranged in sets of two pairs of contacts to form a cruciform pattern. One of the two connectors has solid L-shaped contacts, while the other of the two connectors has a pair of split contact arms that lie and extend in two different planes project from an associated terminal body in a manner so as to mate with the contact portions of the solid L-shaped contacts. The use of L-shaped contacts provides a redundant contact mating arrangement.

International Classification:

H01R 12/00

US Classification:

439 79, 439947

Abstract:

An electrical power connector is mountable on a printed circuit board. The connector includes an outer terminal and an inner terminal, both of which are of generally inverted U-shaped configurations, with the inner terminal nested in the outer terminal. Solder tails project downwardly from bottom edges of side walls of the two terminals. Both terminals have a pair of blade portions projecting forwardly from the respective side walls of the terminals, whereby the blade portions of each terminal are spaced from each other. The blade portions of one terminal are generally coplanar with the blade portions of the other terminal. A dielectric housing is overmolded about the side walls of the outer terminal, leaving the solder tails and the outside surfaces of the blade portions exposed. The housing has a projecting portion extending into the spacing between the blade portions of the two terminals against the inside surfaces of the blade portions, leaving the outside surfaces of the blade portions exposed.

Each metal layer includes a joining section, a contact section and a terminating section. A plurality of projections on the joining sections of the layers are interengaged within a respective plurality of recesses in adjacent layers to align the layers and provide a strong mechanical and good electrical joint between the layers. Solder tails extend linearly along the bottom edge of each joining section to form a plurality of rows of solder tails, and the terminating portions of the metal layers are bent outwardly to separate the rows of solder tails from each other. The contact section of one metal layer may include a generally planar finger which is coplanar with a planar finger of another of the metal layers.
