US Patent:
6443745, Sep 3, 2002
Filed:
Sep 5, 2000
Appl. No.:
09/582847
Inventors:
John R. Ellis - Harrisburg PA
Timothy A. Lemke - Dillsburg PA
Assignee:
FCI Americas Technology, Inc. - Reno NV
International Classification:
H01R 13648
US Classification:
439101, 439608, 439 83
Abstract:
An electrical connector having an insulating housing, a plurality of first contacts ( ), a plurality of second contacts ( ), wherein the connector exhibits a desired characteristic impedance. The second contacts are angled relative to the first contacts and each has an edge ( ) disposed adjacent to an edge or side of first contacts. An electrical connector as described above where the first contacts are signal contacts, the second contacts are power or ground contacts, and the desired impedance is approximately less than 50 ohms.

Cable Connector With A Low Inductance Path

US Patent:
4984992, Jan 15, 1991
Filed:
Nov 1, 1989
Appl. No.:
7/430701
Inventors:
Robert E. Beamenderfer - Palmyra PA
Raymond R. Buchheister - Fairfield PA
John R. Ellis - Harrisburg PA
Charles A. Miller - York New Salem PA
Stanford C. Moist - Hummelstown PA
William E. Zelko - Dauphin PA
Assignee:
AMP Incorporated - Harrisburg PA
International Classification:
H01R 13648
US Classification:
439108
Abstract:
A cable 3 connector 1 comprising, a housing block 2 and an electrical cable 3 having a signal wire 13 connected to a corresponding signal contact 4, and at least one reference wire 14 connected to a reference conductor 5 extending beside the signal contact 4, a housing 6 coupled to the housing 6 block 2 and receiving the signal contact 4 in one of multiple contact positions 7 in the housing 6, and a reference contact 10 received in the housing 6 and connected to the reference conductor 5.

Connector For Electrical Isolation In A Condensed Area

US Patent:
6227882, May 8, 2001
Filed:
Mar 20, 1998
Appl. No.:
9/045660
Inventors:
Jose L. Ortega - Camp Hill PA
John R. Ellis - Harrisburg PA
Assignee:
Berg Technology, Inc. - Reno NV
International Classification:
H01R 466, H01R 13648
US Classification:
439101
Abstract:
An interconnection system having a first connector with a plurality of contacts; and a second connector with a plurality of contacts. The contacts of the first connector engage the contacts on the second connector, creating unbalanced resultant forces an the contacts of the second connector. The unbalanced resultant forces caused by a set of the contacts of the second connector generally offset the unbalanced forces caused by another set of contacts on the second connector. Thus, the contacts balance the forces created during mating, providing a generally balanced interconnection system.

Electrical Cable With Improved Shield

US Patent:
5416268, May 16, 1995
Filed:
Jul 14, 1993
Appl. No.:
8/091577
Inventors:
John R. Ellis - Harrisburg PA
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01B 734
US Classification:
174 36
Abstract:
A transmission cable for transmitting differential logic signals is disclosed having an improved shielding. The cable includes a pair of insulated signal conductors in side by side relation with a layer of electrically conductive material wrapped around the two signal conductors. A non-insulated drain wire is disposed axially along the outside of the wrap of shielding material adjacent one of the signal conductors. The layer of conductive material is continued around the outside of the drain wire thereby forming an additional wrap of the shielding about at least a part of the cable assembly. The drain wire is in electrical engagement with the shielding material.

Connector For Electrical Isolation In Condensed Area

US Patent:
2001001, Aug 2, 2001
Filed:
Feb 13, 2001
Appl. No.:
09/782367
Inventors:
Jose Ortega - Camp Hill PA, US
John Ellis - Harrisburg PA, US
International Classification:
H01R012/00
US Classification:
439/079000
Abstract:
An electrical connector, comprising: a housing; a plurality of signal contacts extending from said housing; and a plurality of ground contacts. Each ground contact has: an L-shaped section located within the housing that shields at least one signal contact from the other signal contacts; and a mating section extending from said housing. The header could have a differential pair arrangement of pairs of columns of signal contacts extending from the housing; and columns of ground contacts flanking the pairs of columns of signal contacts. Two columns of ground contacts preferably flank each side of two columns of signal contacts.
