Abstract
An electrical connector may include a first connector with electrically-conductive contacts. The contacts may have blade-shaped mating ends, and may be arranged in a centerline. The electrical connector may include a second connector with electrically-conductive receptacle contacts, which may also be arranged in a centerline. The connectors may be mated such that the mating portion of a first contact in the second connector may physically contact of a corresponding blade-shaped mating end of a contact in the first connector.
Claims36
An electrical connector comprising:
- a plurality of insert molded leadframe assemblies (IMLA), each IMLA including a leadframe housing that supports four edge coupled differential signal pairs and interleaved ground contacts along a respective leadframe housing centerline, wherein the four differential signal pairs and the respective interleaved ground contacts of each IMLA fit within a 25 mm card pitch, and wherein a pair of the interleaved ground contacts are (1) separated by one of the four differential signal pairs of a first IMLA, and (2) define a distance of approximately 3.6 mm from a centerline of a first ground contact of the pair of interleaved ground contacts to a centerline of the other ground contact of the pair of interleaved ground contacts.
An electrical connector comprising:
- a plurality of IMLAs, each IMLA including a leadframe housing that supports five edge coupled differential signal pairs and interleaved ground contacts along a respective leadframe housing centerline, wherein the five differential signal pairs and respective interleaved ground contacts of each IMLA fit within a 21 mm card pitch.
An electrical connector comprising:
- a plurality of IMLAs, each IMLA including a leadframe housing that supports six edge coupled differential signal pairs and interleaved ground contacts along a respective leadframe housing centerline, wherein the six differential signal pairs and respective interleaved ground contacts of each IMLA fit within a 35 mm card pitch, and wherein a pair of the interleaved ground contacts are (1) separated by one of the six differential signal pairs of a first IMLA, and (2) define a distance of approximately 3.6 mm from a centerline of a first ground contact of the pair interleaved ground contacts to a centerline of the other ground contact of the pair of interleaved ground contacts.
