  • Patent number: 5290191
    Abstract: A wafer-like insert has a plurality of holes therein which correspond to pins of an electrical connector. The wafer includes contacts for making electrical connection to the pins, connector shell or electrical components. In such manner, the wafer can be used for a wide variety of purposes such as conditioning signals carried by the pins and grounding selected pin(s) to each other and/or the connector shell. The wafer can be installed in any common electrical connector pair without prior modification or preparation of the connectors and without impairing the normal fit or function of the mated connector pair.

  • Patent number: 5059143
    Abstract: The present disclosure sets forth a unique contact structure for a separable electrical connector for carrying relatively high levels of current at high frequency in a high temperature environment. The contact utilizes a high loading spring design which permits a relatively low resistance and low inductance contact element. The contact element takes either of two forms. One form being a multiple wire spring formed in an open helical pattern and the other being a number of c-shaped contact elements arranged in concentric circles on a thin disk.

  • Patent number: 5023505
    Abstract: An electric lamp is provided including a sealed outer glass envelope having an arc tube therein supported from the stem of the outer glass envelope by a support frame. The support frame is attached to the stem by a stem clip to which the support frame is welded. An inert refractory fibrous material is disposed between the stem and the stem clip to provide resiliency and a friction fit therebetween.

  • Patent number: 4943247
    Abstract: An annular electrical terminal member 14 adapted to reduce resistance at a contact interface between two electrical articles has a fastener receiving aperture 16 extending therethrough, an inner edge 22 adjacent the fastener receiving aperture 16 and an outer edge 28 extending circumferentially therearound. A plurality of slots 26 are spaced around the annular section, the slots 26 defining therebetween respective spring sections 32 in an annular array. Each of the spring sections includes a respective protrusion 34 extending from one major surface thereof, the protrusion having a crest portion 36, the respective crest portions 36 being disposed substantially in a common plane. The crest portions 36 comprise a contact interface for electrical engagement with a common conductive surface 38 of the first electrical article 60. The other terminal major surface has an array of surface portions engageable by a second electrical article.

  • Patent number: 4674807
    Abstract: An electrical connector has an electrically non-conductive outer housing and connector members recessed in one end of the housing. Electromagnetic interference shielding is provided by members surrounding the components within the housing including an electrically conductive grommet circularly contacting conductive braid on the cable to which the connector is attached and a sleeve which surrounds the wires within the housing and extends axially to the connector end. One of the connector prongs is designated as the ground prong and is electrically attached to the sleeve. Embodiments accommodating three and four wires are disclosed.
