Abstract
An electrical connector with electrically lossy materials bridging ground members. The lossy conductive members may be formed by filling a settable binder with conductive particles, allowing the partially conductive members to be formed through an insert molding process. Connectors assembled from wafers that contain signal conductors held within an insulative housing may incorporate lossy conductive members by having filled thermal plastic molded onto the insulative housing. The lossy conductive members may be used in conjunction with magnetically lossy materials. The lossy conductive members reduce ground system do resonance within the connector, thereby increasing the high frequency performance of the connector.
Claims32
An electrical connector comprising:
- a plurality of contact elements;
- a plurality of discrete conductive elements each disposed adjacent at least one of the contact elements;
- insulative material securing at least the plurality of contact elements;
- and
- electrically lossy material including,
- a first portion adjacent and spaced apart from the plurality of contact elements and the plurality of discrete conductive elements, and
- a plurality of second portions, each of the plurality of second portions extending between the first portion and at least one of the plurality of discrete conductive elements and spaced apart from the plurality of contact elements.
An electrical connector comprising:
- a first plurality of conducting members, each connected to a ground structure;
- a second plurality of conducting members, each connected to at least one of a plurality of signal traces with at least two conducting members of the first plurality of conducting members positioned adjacent to conducting members of the second plurality of conducting members;
- and
- an electrically lossy material including,
- a first portion adjacent and spaced apart from the first plurality of conducting members and the second plurality of conducting members, and
- a plurality of second portions, each of the plurality of second portions extending between the first portion of the electrically lossy material and at least one of the first plurality of conducting members and spaced apart from the second plurality of conducting members;
- wherein at least one of the plurality of second portions of the electrically lossy material makes direct contact with one of the first plurality of conducting elements.
