US Patent:
20130126212, May 23, 2013
Filed:
Jul 23, 2012
Appl. No.:
13/555911
Inventors:
Rodney Ivan Martens - Mechanicsburg PA, US
Andrew Nicholas Loyd - Dillsburg PA, US
Jessica Henderson Brown Hemond - Mifflintown PA, US
Zhengwei Liu - Houston TX, US
Assignee:
Tyco Electronica Corporation - Berwyn PA
International Classification:
H01B 5/00
B32B 37/14
US Classification:
1741262, 156 622
Abstract:
A conductive member includes a metal substrate and a carbon-based substrate (CBS) network applied to the metal substrate. The CBS network includes a framework of fibers and particulates embedded in the framework that provide cathodic protection for the metal substrate. The particulates may penetrate entirely through the framework. The particulates may be iron particulates. The particulates may be metal particulates having a higher corrosion potential than the metal substrate. The CBS network may be a yarn, a sheet, or a tape. The CBS network with the particulates may be applied by coating or plating the metal substrate with the CBS network.

B82Y 40/00
B82Y 99/00
US Classification:
174257, 427122, 977890, 977734
Abstract:
A method of manufacturing an electrical conductor includes providing a substrate layer, depositing a surface layer on the substrate layer that has pores at least partially exposing the substrate layer, and forming graphene deposits in the pores. Optionally, the graphene deposits may be formed only in the pores. The graphene deposits may be formed along the exposed portions of the substrate layer. The graphene layers may be selectively deposited or may be deposited to cover an entire layer. Optionally, the forming of the graphene deposits may include processing the electrical conductor using a chemical vapor deposition process using an organic compound precursor and heat of sufficient temperature to facilitate graphene growth on the metal compound comprising the substrate layer.

Termination Of Carbon Nanotube Macrostructures

US Patent:
20130217279, Aug 22, 2013
Filed:
Nov 6, 2012
Appl. No.:
13/669817
Inventors:
Tyco Electronics Corporation - , US
Jerzy Gazda - Austin TX, US
Zhengwei Liu - Houston TX, US
Rodney Ivan Martens - Mechanicsburg PA, US
Min Zheng - Harrisburg PA, US
Assignee:
Tyco Electronics Corporation - Berwyn PA
International Classification:
H01R 4/10
B82B 1/00
US Classification:
439878, 977742
Abstract:
An electrical connector has a carbon nanotube (CNT) conductor, a terminal terminated to the CNT conductor, and a conductive intermediary electrically coupled to the CNT conductor and the terminal to enhance an electrical connection between the CNT conductor and the terminal. Optionally, the terminal may have a crimp barrel that receives the CNT conductor. The electrical connector may include a second CNT conductor where the terminal splices the CNT conductor and the second CNT conductor together.

US Patent:
20130292161, Nov 7, 2013
Filed:
May 1, 2012
Appl. No.:
13/461135
Inventors:
Zhengwei Liu - Hershey PA, US
Min Zheng - Harriisburg PA, US
Rod Martens - Mechanicsburg PA, US
Assignee:
Tyco Electronics Corporation - Berwyn PA
International Classification:
H05K 1/09
B05D 5/12
C25D 5/02
B82Y 40/00
B82Y 30/00
US Classification:
174257, 427122, 205122, 977734, 977847
Abstract:
A method of manufacturing an electrical conductor includes providing a substrate layer, depositing a graphene layer on the substrate layer and selectively depositing boundary cappings on defects of the graphene layer to inhibit corrosion of the substrate layer at the defects. Optionally, the boundary cappings may include nano-sized crystals deposited only at the defects. The selectively depositing may include electrodepositing boundary cappings on exposed portions of the substrate layer at the defects. The selectively depositing may include reacting boundary capping material with exposed portions of the substrate layer at the defects to deposit the boundary cappings only at the defects.
