Patent number: 7015708Abstract: A spring loaded, high frequency, controlled impedance, coaxial probe assembly located within an insulated or conductive housing. A high frequency coaxial probe assembly consisting of a central contact which is fixed or axially floating within a controlled impedance connector body or assembly. A flexible, elastically de-formable, fixed or field replaceable and detachable, ground contact, snapped on and retained in place upon the controlled impedance connector body or assembly creating a fixed or axially floating reference plane or dimension from which the head of the probe contact will protrude through the controlled impedance connector body. The individual, high frequency, controlled impedance, coaxial probe assemblies are spring loaded to provide continuous axial signal contact, when deployed to a planar device such as a DUT (Device Under Test) board. The flexible, elastically de-formable, fixed or field replaceable and detachable, ground contact(s) provide a resilient and continuous wiping action.Type: GrantFiled: July 11, 2003Date of Patent: March 21, 2006Assignee: Gore Enterprise Holdings, Inc.Inventors: Frank R. Beckous, Paul A. Czikora, John J. Squires

Patent number: 5099393Abstract: An electronic package including a first circuitized substrate (e.g., printed circuit board) and a flexible circuitized substrate wherein the flexible substrate is precisely aligned in removable manner relative to the first substrate. This is accomplished utilizing a retention member and associated frame member, the flexible circuitized substrate being precisely aligned and secured to the frame member. Elastomeric pressure exertion members are utilized to exert pressure against each of a plurality of individual circuitized sections of the flexible circuit member to thus effect engagement between the flexible substrate's contacts and respective conductors which constitute part of the circuit on the first substrate. Moveable clamp members may also be used to engage extending posts of the retention member, said clamp members also possibly acting against a stiffener member located on the first substrate's opposite surface from the flexible substrate.Type: GrantFiled: March 25, 1991Date of Patent: March 24, 1992Assignee: International Business Machines CorporationInventors: James R. Bentlage, David E. Engle, Geoffrey R. Mariner, John J. Squires, John H. Williams

Patent number: 5059129Abstract: An electrical connector assembly including a bilayered elastomeric element of integral construction for providing effective contact force (pressure) between corresponding arrays of conductors located on two circuit members (e.g., one a flexible circuit and the other a more rigid, circuit board or card). High density connections are assured in a sound, effective manner. The elastomer, preferably silicon rubber, includes a base layer with several spaced openings therein and an adjacent layer of several upstanding projections (e.g., cylindrical or box-like) spacedly located relative to the adjacent openings within the first layer. The first layer openings accommodate bulged elastomeric during compression to assist in preventing undesirable elastomeric buckling, thereby assuring the desired contact force (pressure) application.Type: GrantFiled: March 25, 1991Date of Patent: October 22, 1991Assignee: International Business Machines CorporationInventors: William L. Brodsky, Thomas G. Macek, John J. Squires

Patent number: 4975068Abstract: An electrical connector for electrically connecting the circuitry on a pair of flexible cables, the connector including a base member for having the two cables located thereon, means for aligning the two cables in precise alignment (e.g., a pair of pins on the base member), a clamp member for occupying first and second positions relative to the base member (the flexible cables being compressed and the circuitry thereof being in direct contact when the clamp is in the second position), compressible means (e.g., an elastomeric member) located between the clamp and base members for engaging at least one of the flexible cables to exert a force thereagainst when compressed, and retention means for retaining the clamp member in the second (clamping) position such that a high density connection is provided between both flexible cables. In one embodiment, the clamp is pivotally located on the base member, while in another embodiment the retention means is rotationally located on the clamp member.Type: GrantFiled: December 4, 1989Date of Patent: December 4, 1990Assignee: International Business MachinesInventor: John J.

Patent number: 4953929Abstract: A fiber optic connector assembly wherein two individual fiber optic connectors are retained in a side-by-side arrangement which enables relative freedom of movement therebetween so as to facilitate positioning of the retained two (also called a duplex) within a common housing. Such movement accommodates for manufacturing tolerances within the housing and/or connectors, while still assuring successful insertion within the common housing. An adapter, having two clamping portions (one for each connector) interconnected by a resilient portion, assures this movement.Type: GrantFiled: July 21, 1989Date of Patent: September 4, 1990Assignee: International Business MachinesInventors: Joseph F. Basista, Wai M. Ma, John J. Squires

Patent number: 4907975Abstract: An assembly for interconnecting two relatively rigid circuit cards using a flexible circuit for forming this connection is provided. The assembly includes a housing which has a first pressure exerting member which has the flexible circuit reeved therearound. Second and third pressure exerting members are provided in spaced juxtaposed relationship against which the opposite legs of the flexible circuit are maintained to define therebetween a slot for the reception of a circuit card. The assembly is inserted into a card substrate with the first pressure exerting means causing the flexible circuit to be biased into contact with the contacts on a substrate. A second circuit card is inserted into the slot between the legs of the flexible circuit, and the second and third pressure exerting members urge each of the legs as the flexible circuit into contact with the second circuit board.Type: GrantFiled: December 19, 1988Date of Patent: March 13, 1990Assignee: International Business Machine CorporationInventors: David W. Dranchak, David E. Engle, David E. Hessian, Alan D. Knight, Wai M. Ma, Thomas G. Macek, John J. Squires
