Abstract:
In an electrical connector, a non-grounded, electrically conductive material (such as copper foil or other sheet of metal) may be located adjacent to at least one differential signal pair. An example includes a ring of material that circumscribes a leadframe assembly. Ring-shaped structures placed around, but not in contact with, the signal and ground contacts effectively mitigate cross-talk resonances in the interconnection structure.
Abstract:
Example electπcal connectors are provided including a plurality of electrical contacts configured to communicate between electrical devices. The plurality of electrical contacts includes a plurality of ground contacts. A ground coupling assembly is configured to electrically connect ground contacts of an electrical connector to adjust a performance characteristic of the electrical connector as desired.
Abstract:
Methods for setting contact height in an electrical connector are disclosed. Each of a plurality of electrical contacts (10) may be seated in a connector housing (20) such that each contact (10) has a respective initial height relative to the housing. At least one of the contacts (10) is pressed on such that, after the pressing, each of the contacts has approximately the same height relative to the connector housing (20). The pressing may bend the at least one contact at least until it has set. Before the pressing, the initial contact heights have a first tolerance. After the pressing the pressed contact heights have a second tolerance that is smaller than the first tolerance.
Abstract:
Electrical connectors and contacts for transmitting power are provided. One power contact embodiment includes a first plate that defines a first non-deflecting beam and a first deflectable beam, and a second plate that defines a second non-deflecting beam and a second deflectable beam. The first and second plates are positioned beside one another to form the power contact.
Abstract:
Electrical connectors and contacts are disclosed. An electrical connector may include a housing (120) having a contact receiving well (122) that extends along a contact receiving direction, the contact receiving well having a generally T-shaped cross-section along a direction transverse to the contact receiving direction. An electrical contact (100) may be received in the contact receiving well. The contact may include a generally planar body portion (102), a first contact portion (104) extending from a first end (102A) of the body portion, and a second contact portion (106) extending from a second end (102B) of the body portion. The contact is adapted to be received into a generally T-shaped contact receiving well (122) such that the contact receiving well prevents movement of the electrical contact within the contact receiving well.
Abstract:
Disclosed is an electrical connector that includes a dielectric leadframe housing and a differential signal pair of electrical contacts extending through the leadframe housing. The leadframe housing defines an air pocket adjacent to the pair of electrical contacts. The size of the air pocket may be predetermined to provide for no more than a predefined amount of signal skew between the pair of electrical contacts. The size of the air pocket may be predetermined to provide for a predefined connector impedance.
Abstract:
An electrical connector includes a dielectric housing, a plurality of electrical signal contacts carried by the dielectric housing, and a ground plate carried by the dielectric housing. The electrical signal contacts are arranged along a first plane, wherein the signal contacts define signal pairs such that a respective gap is disposed between adjacent signal pairs. The signal contacts further define respective mating and mounting ends. The ground plate includes a ground plate body oriented in a second plane that is substantially parallel to the first plane and offset from the first plane. The ground plate includes at least one rib that defines first and second opposed surfaces, wherein the first surface of the rib projects from the first surface of the ground plate body in a direction toward the gap, and the second surface is recessed into the second surface of the ground plate body.
Abstract:
An electrically-conductive contact for an electrical connector is disclosed. Such a contact may include a lead portion, an offset portion extending from an end of the lead portion, and a mounting portion that may extend from a distal end of the offset portion. The lead portion and the distal end of the offset portion may each define an imaginary plane that may intersect at a non-zero, acute angle. An electrical connector that is suitable for orthogonal connector applications may include a connector housing securing two such electrical contacts. The distance between the respective mounting portions of the two such contacts may be defined independently of the contact pitch.
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.
