    摘要: An assembly for passing controlled impedance electrical signals between two different environments via feedthroughs in an electrically-conductive feedthrough block. The feedthrough has a signal coupling, a dielectric spacer surrounding the signal coupling, and a ground coupling surrounding the dielectric. The feedthrough is sealed to hermetically separate the two environments. One or both ends of the dielectric are recessed from the face of the block forming a gap. The gaps is filled with a potting material to form the hermetic seal.

    摘要: A cable termination that enables the attachment of SMA connectors to controlled-impedance cables with a conductive foil wrap shield; for the separate ferrule embodiment, the sheath is stripped back on the cable, exposing the foil shield surrounding the dielectric; a ferrule is slid or clamped over the foil shield and bonded; the face of the ferrule is dressed so that the foil shield and dielectric are flush with the ferrule face and the signal conductor protrudes from the face this cable subassembly is installed in the boss of a housing that prevents movement of the ferrules relative to each other and so that each ferrule face is aligned with an opening in the boss through which an SMA connector barrel is attached to the ferrule a cover secures the cable subassembly in the housing.

    摘要: An apparatus for terminating a controlled-impedance cable using compliant electrical contacts to provide an interface to another device. The terminator includes a conductive ground block for securing the cable by its ground shield and providing a common ground. Once the cable is anchored in the ground block, the block face and cable ends are dressed to make a reliable electrical contact with the compliant signal contact that electrically connects the cable center conductor to the device. An insulating or conductive plate mounted to the ground block holds the signal contact and optional ground contacts that electrically connect the ground block to the ground plane of the device. The ground contacts surround the signal contact in a pattern that closely mimics the impedance environment of the cable. When using a conductive plate, the signal contact is insulated from the plate by an insulating centering plug or a non-conductive coating. A controlled-impedance cable terminator using compliant electrical contacts to provide an interface to another device. The terminator includes a conductive plate with a face surface and a device surface. Signal through holes extend between the face surface and device surface. Each signal through hole has an insulating centering plug with a signal through aperture that has openings in the face surface and the device surface. The signal through aperture holds a skewed coil signal contact with contact points extending from each signal through aperture opening. Optionally, the plate includes ground through apertures that surround the signal through aperture. Each ground through aperture has openings in the face surface and device surface. The ground through aperture holds a skewed coil ground contact with contact points extending from each ground through aperture opening.

    摘要: A fixture for probing circuit boards and microcircuits. A guide plate provides indexing for positioning a probe assembly in one or two dimensions. The guide plate has two opposed mounting sides connected by one or two indexing sides and is mounted to the test unit by screws. The indexing sides and, optionally, the mounting sides have column mounting holes and column markings. A bridge mounts to the indexing sides with its column pointer aligned with the desired column marking. The bridge has row mounting holes and row markings. The probe assembly mounts to the bridge with its row pointer aligned with the desired row marking. Optionally, the bridge is part of the probe assembly and without row indexing elements to be used in one dimension. The probe assembly has a terminator platform and connector plate with electrical cable assemblies extending therebetween.

    摘要: An apparatus for terminating a controlled-impedance cable using compliant electrical contacts to provide an interface to another device. The terminator includes an anchor block for securing the cable. Optionally, the anchor block is electrically non-conductive. A conductive ferrule is installed on the cable shield and the cable end is dressed. The ferrule/cable assembly is installed in a through hole in the anchor block so the cable end is flush with the anchor block face. An insulating or conductive plate mounted to the anchor block holds the signal contact that electrically connects the center conductor to the device and optional ground contacts that electrically connect the ferrule to the device. The ground contacts surround the signal contact in a pattern that closely mimics the impedance environment of the cable. When using a conductive plate, the signal contact is insulated from the plate by an insulating centering plug or a non-conductive coating.

    摘要: An assembly for passing controlled impedance electrical signals between two different environments via feedthroughs in a feedthrough block. The feedthrough has a signal coupling, a dielectric surrounding the signal coupling, and a ground coupling surrounding the dielectric. An electrically insulating block has an electrically conductive signal link and discrete electrically conductive ground links surrounding the signal link. An electrically conductive block has a separate dielectric spacer and signal link through the spacer. The junctions between the block, links, and spacer are sealed to hermetically separate the two environments. In one method, the components are press fit, leaving no gap between adjacent components. In another method, potting material is forced into the junctions between components.

    摘要: A controlled-impedance cable termination that minimizes the effects of cable expansion and contraction on impedance matching. The terminator has an anchor block, an expansion/contraction compensator (ECC) attached to the cable, a compliant signal contact for making the electrical connection between the cable center conductor and the electrical device. The ECC has an electrically-conductive ferrule with a bore. The ferrule bore may be formed in the anchor block instead of in a separate ferrule. The cable shield is attached at the bore. A solid dielectric insert fits into the ferrule bore. An electrically-conductive center pin fits into a bore in the dielectric insert and has a bore that accepts the center conductor such that the center conductor can expand and contracting while maintaining electrical contact with the center pin. A plate abuts the anchor block face and holds the compliant contacts through apertures.
