High Power Multi-Pin Electrical Connector

View page
US Patent:
20110059638, Mar 10, 2011
Filed:
Sep 4, 2009
Appl. No.:
12/554542
Inventors:
Graeme Richard Sandwith - Chicago IL, US
International Classification:
H01R 13/52
H01R 43/20
US Classification:
439271, 29747
Abstract:
This patent discloses an improved multi-pin electrical connector for use in wet environments. Multi-pin connectors are widely used. In some uses, the connectors may be exposed to water. The improved connector keeps external water from entering the connector and isolates any water inside the connector. A number of improvements are disclosed, including seals for the pins, seals for the wires exiting the back of the connector, and bonding internal insulator materials. The invention also incorporates an improved female receptacle design that provides a better male-to-female connection, thus improving performance of the connector. The multi-pin connector disclosed is suitable for use in almost any wet environment.

US Patent:
20150214660, Jul 30, 2015
Filed:
Jan 24, 2014
Appl. No.:
14/162943
Inventors:
- Chicago IL, US
Graeme Sandwith - Chicago IL, US
Assignee:
Electrical Equipment Corporation - Chicago IL
International Classification:
H01R 13/631
Abstract:
An electrical contact or electrical contact system includes a connector and a conductive band, the band configured to be disposed within a groove in the connector. The groove may include an undercut configured to receive and secure a portion of the band. The band may be ladder-like in structure, with a plurality of rung-like elements separating a pair of rails, and the portion of the band that may be received by the groove preferably corresponds to no more than at least a part of one rail. The system also may include a retention element, such as a snap ring, which may be configured to fill in the portion of the groove not occupied by the band, thereby holding the band in place and preventing it from becoming dislodged.

US Patent:
20140273586, Sep 18, 2014
Filed:
Mar 15, 2013
Appl. No.:
13/842395
Inventors:
- Chicago IL, US
Graeme Sandwith - Chicago IL, US
Assignee:
ELECTRICAL EQUIPMENT CORPORATION - Chicago IL
International Classification:
H01R 13/516
US Classification:
439345, 439725
Abstract:
An electrical connector system including contacts configured to electrically couple to cables at one end and to one another at the other end. Contacts may be housed in rubberized insulations, which in turn may be housed in various types of receptacles, e.g., bulkhead mounts, wall mounts, in line connectors, or caps. Male contact may be disposed within opening of female contact, but insulation surrounding male contact may be configured to envelope insulation surrounding female contact. As a result, an overall diameter of insulations and contacts may be reduced significantly, permitting the use of receptacles sized to accommodate openings previously reserved for metal-on-metal insulating connection systems.
