Abstract:
A bearing (24, 86) adapted to support and allow controlled relative movement with an opposed bearing surface. The bearing is constructed to have a long life by incorporating a locally compliant surface that addresses many causes of friction and wear. The bearing (24, 86) includes a plurality of support members (28) extending from a base. Together, the plurality of support members (28) can support a load applied perpendicular to the base through an opposed bearing. Additionally, the plurality of support members (28) allow sliding contact between the opposed bearings. The support members (28) can move independently to accommodate irregularities located between the support member and the opposed bearing, such that plowing is reduced and wear to the bearings is minimized. Also, the support members (28) maintain the distance between the opposed bearing when any foreign particle or asperity causes one or more of the support members to flex independently on a localized basis.

These support members (28) can move independently to accommodate irregularities located between the support member (28) and the opposed bearing, such that plowing is reduced and wear to the bearings is minimized. The support members (28) may also be configured to allow certain non-sliding modes of motion between opposed bearing surfaces while resisting other non-sliding modes of motion.
Abstract:
The present disclosure is directed to electrical switches that utilize conductors that are woven onto loading fibers and a mating conductor that has a contact mating surface. Each conductor has at least one contact point. The loading fibers are capable of delivering a contact force at each contact point of the conductors. Electrical connections are established between the contact points of conductors and the contact mating surface of the mating conductor when the conductor-loading fiber weave is engaged with the mating conductor and the electrical connections are terminated when the conductor-loading fiber waeve is disengaged from the mating conductor. In one embodiment, the portion of the contact mating surface of the mating conductor where arcing between the conductors and the mating is expected to occur is plated with a conductive arc-tolerant material, such as silver, for example. In another embodiments, the portions of the conductors where arcing is expected to occur are plated with a conductive arc-tolerant material. In an alternate embodiment, the conductors are made thicker where arcing between the conductors and the mating conductor is expected to occur. The contact mating surface of the mating conductor can include a non-conductive portion that assists in guiding the conductor-loading fiber weave when its being engaged and disengage from the mating conductor.

Abstract:
An electrical connector that has an array of conductors each having a contact point to make contact with a mating conductive surface. Upon engaging the contact points in a sliding manner with the mating surface, the conductors are displaced, which, in turn, tensions a loading fiber within the connector. Tensioning of the loading fiber provides a contact force between the contact points and the mating surface.
Abstract:
Electrical connectors are adapted to provide a reliable electrical connection to mating elements of a mating connector. The connector can have sockets that accept mating elements of the mating connector. Conductors of the connector are associated with each socket and make electrical contact with mating elements received therein. A loading band of the connector is tensioned to provide a contact force between the conductor and the mating element when the mating connector is in the socket. Electrical connectors constructed in this manner can provide increased current density and/or a more reliable connection between the conductors and the mating element.

An electrical connector having one or more electrical contacts for providing an electrical connection to an inserted pin is provided. The electrical connector includes a spring made of electrically conductive material and a loading element attached to the spring and arranged to define an opening for pin insertion. The spring is physically arranged relative to the loading element to create a tension on the loading element. The electrical connector includes at least one conductive wire in electrical communication with the spring. The wire is wound around the spring and the loading element, providing multiple electrical contact points radially inward relative to a center of the opening to provide electrical contact to the inserted pin. When the pin is inserted into the opening, the loading element is tensioned such that the loading element generates a contact force at each contact point.
