High-frequency electrical connector

摘要

An electrical connector with improved high frequency performance. The connector has conductive elements, forming both signal and ground conductors, that have multiple points of contact distributed along an elongated dimension. The ground conductors may be formed with multiple beams of different length. The signal conductors may be formed with multiple contact regions on a single beam, with different characteristics. Signal conductors may have beams that are jogged to provide both a desired impedance and mating contact pitch. Additionally, electromagnetic radiation, inside and/or outside the connector may be shaped with an insert electrically connecting multiple ground structures and/or a contact feature coupling ground conductors to a stiffener. The conductive elements in different columns may be shaped differently to reduce crosstalk.

1. An electrical connector comprising:
a housing; a plurality of conductive elements disposed in a column, each of the plurality of conductive elements comprising a mating contact portion, a contact tail, and an intermediate portion between the mating contact portion and the contact tail, wherein:
the intermediate portions of the plurality of conductive elements are disposed within the housing and the mating contact portions of the plurality of conductive elements extend from the housing;the plurality of conductive elements comprises a first conductive element and a second conductive element disposed adjacent the first conductive element; anda first proximal end of a first mating contact portion of the first conductive element is spaced apart from a second proximal end of a second mating contact portion of the second conductive element by a first distance, wherein the first mating contact portion of the first conductive element comprises a first beam and a second beam, and wherein the second mating contact portion of the second conductive element comprises a third beam and a fourth beam; andthe first and second beams of the first conductive element jog away from the second conductive element and the third and fourth beams of the second conductive element jog away from the first conductive element, such that a first distal end of the first mating contact portion of the first conductive element is spaced apart from a second distal end of the second mating contact portion of the second conductive element by a second distance that is greater than the first distance.
