Cable Guide And Method Of Cable Termination

US Patent:
8525034, Sep 3, 2013
Filed:
Feb 28, 2011
Appl. No.:
13/036064
Inventors:
Alan L. Roath - Madison OH, US
Corinne W. Baumann - Mentor OH, US
Assignee:
Ohio Associated Enterprises, LLC - Painesville OH
International Classification:
H01B 7/00, H02G 3/04, H02G 3/00, H05K 1/00, H01R 43/00
US Classification:
174135, 174 681, 174 70 R, 174250, 29868
Abstract:
A cable guide is used to constrain and locate wires or cables for preparation for and for connection to a circuit board or connector, for termination. The cable guide has openings that receive and secure wires during the termination process. A shaft of the cable guide may be used to secure, in a repeatable manner, a predetermined length of the wires with ends offset from a cable jacket, or other reference on or near the end of the cable. The cable guide and the cable/wires may be secured in a fixture that allows the wire ends to be repeatably scored to remove insulation.

Fastener For A Printed Circuit Board Mounted Connector

US Patent:
5316500, May 31, 1994
Filed:
Jan 11, 1993
Appl. No.:
8/002659
Inventors:
Alan L. Roath - Madison OH
Assignee:
Ohio Associated Enterprises, Inc. - Painesville OH
International Classification:
H01R 1373
US Classification:
439567
Abstract:
A fastener for securing a connector body over a hole in a printed circuit board comprises a clip rigidly supported by the connector body and a wedge supported by the connector body for sliding movement along the clip. In one form, the clip includes a pair of resilient arms having free ends extending outside the body. The resilient arms have teeth or other means near their free ends for engaging the inner surfaces of the hole. The arms converge toward each other near their free ends to retract the teeth when the arms are in an unengaged condition. The wedge includes a portion which extends between the arms for spreading the arms and teeth as the wedge slides along the clip toward the free ends of the arms. The fastener is secured in the hole by inserting the clip arms into the hole and pressing the wedge into the hole toward the free ends of the arms. Advantages of the fastener include no protrusion through the opposite surface of the board, low insertion force and relative insensitivity to tolerance stack-ups.

Oct 3, 1986
Appl. No.:
6/914803
Inventors:
John N. Tengler - Chico CA
Alan L. Roath - Madison OH
John T. Venaleck - Madison OH
Assignee:
Minnesota Mining and Manufacturing Company - Saint Paul MN
International Classification:
H01R 1718

Electrical Contact With Redundant Contact Points

US Patent:
2013010, Apr 25, 2013
Filed:
Oct 22, 2012
Appl. No.:
13/657211
Inventors:
Alan L. Roath - Madison OH, US
Assignee:
OHIO ASSOCIATED ENTERPRISES, LLC - Painesville OH
International Classification:
H01R 13/28
US Classification:
439295
Abstract:
An electrical connection between hermaphroditic contacts includes redundant contact points. Each of the contacts may have ridges on bent or curved portions, for making contact with straight portions of the other contact. The ridges may be parallel to one another. The mating allows both pairs of contact points to be maintained even when there is some misalignment between the contacts, due to beam rotation caused by torsional compliance. The connection provides great reliability.

High Performance Test Interface

US Patent:
6316954, Nov 13, 2001
Filed:
Jul 13, 1999
Appl. No.:
9/352797
Inventors:
John T. Venaleck - Painesville OH
John Tengler - Chico CA
Alan L. Roath - Madison OH
Assignee:
Ohio Associated Enterprises, Inc. - Painesville OH
International Classification:
G01R 3102
US Classification:
324761
Abstract:
A test interface is used to connect an electronic device under test ("DUT"), such as a computer chip, to a tester. The interface utilizes a combination of spring forces and air pressure forces to extend and retract pogo pins, respectively. The pogo pins when extended contact conductive pads which are electrically connected to the DUT, perhaps via a DUT board. Springs are biased to extend the pins to contact the pads, and air pressure is used to retract the pins. Thus no air pressure or vacuum is required to maintain the pins in contact with the pads. When retracted, the pogo pins are shielded from damage by a shield, such as a board with holes in it for the pogo pins to pass through.

Press-Fit Pins For Making Electrical Contact With Vias

US Patent:
2007000, Jan 11, 2007
Filed:
Jul 8, 2005
Appl. No.:
11/177564
Inventors:
Alan Roath - Madison OH, US
John Venaleck - Painesville OH, US
International Classification:
H01R 12/06
US Classification:
174267000, 439082000
Abstract:
A press-fit pin for making electrical contact with a via is a self-supporting pin having a serpentine shape. The pin may have at least two bends therein, so as to make contact with the via at multiple pairs of contact points separated longitudinally along the length of the pin. This use of a single-member contact with the via may allow use of smaller vias. In a direction longitudinally down the pin, successive pairs of contact points may be on opposite sides of the pin, so as to provide normal forces on opposite sides of the via and the pin, thus tending to provide some degree of balance in forces between the pin and the via. The pin may have rounded, coined corners and a tapered tip, in order to facilitate insertion of the pin into the via, without undue force, and without damage to either the pin or the via.

Zero Insertion Force Cable Interface

US Patent:
7316579, Jan 8, 2008
Filed:
Sep 18, 2006
Appl. No.:
11/522685
Inventors:
Alan L. Roath - Madison OH, US
John T. Venaleck - Painesville OH, US
Assignee:
Ohio Associated Enterprises, LLC - Painesville OH
International Classification:
H01R 13/15
US Classification:
439260, 439265, 439267, 439268
Abstract:
An electrical connector includes a cable end connector which mates with a board mount connector. The cable end connector includes a plurality of header modules that each include pivotal contact-bearing headers. The headers are coupled to ribbon conductors in a parallel planar array. One end of each of the headers has conductors prepared to accept the welding of ribbonized coaxial cables. The other end of the conductors form compliant contacts for engagement with other compliant contacts or with pads arranged on the edge of a circuit board. Headers of each module have posts that emanate from lateral sides of a header body, distal from the compliant contact ends, that function as cam sliders. The cam sliders are located in slots, and engage ramps, which may be moved to urge the contacts of the headers together or apart.

Zero Insertion Force Cable Interface

US Patent:
7291031, Nov 6, 2007
Filed:
Jul 8, 2005
Appl. No.:
11/177658
Inventors:
Larry M. Crofoot - Perry OH, US
Alan L. Roath - Madison OH, US
John T. Venaleck - Painesville OH, US
Assignee:
Ohio Associated Enterprises, LLC - Painesville OH
International Classification:
H01R 13/15, H01R 13/62
US Classification:
439265, 439259
Abstract:
A connector assembly includes a female dual row connector, and a male dual row connector configured to be inserted into the female dual row connector. The female connector is configured to be compression mounted onto a circuit card, and has conductive tails for being brought into contact with traces on the card or circuit board. The female connector may have a stiffener to help it maintain its shape. The rows of contacts of the male connector may be selectively brought together (collapsed) or moved apart (expanded). The rows of contacts are collapsed during insertion or removal of the male connector from the female connector, thus allowing zero force insertion of the male connector into the female connector. The collapsing and expanding of the rows for the male connector may be accomplished through any of a variety of mechanisms.
