摘要:
An interconnection device is disclosed for providing electrical connection between two conducting elements that requires less applied force than a standard ohmic connection device of the same connection area. A surface of at least a first conducting element includes a plurality of atomically sharp projections for creating a strong electric field near the tip of each projection, each projection being disposed within a locally depressed portion of an insulating layer that serves to maintain a space between each tip and a second conducting element that contacts the insulating layer. The strong electric field at each tip induces a variety of conduction modes each contributing to an aggregate current flow from the first conducting element to the second. In an alternate embodiment, a plurality of projections are disposed on the peaks and valleys of a rough surface without an insulating layer, the projections providing a variety of conduction modes.

A radio frequency coupler connector includes a housing having first and second housing portions. The first housing portion includes a first open-ended launcher operatively connected to a first connection terminal, and the second housing portion includes a second open-ended launcher operatively connected to a second connection terminal. When the first and second housing portions are assembled, the first and second open-ended launchers are overlapped and separated by a dielectric, thereby providing a non-contact connection by capacitive coupling.

A connector assembly utilizes improved capacitive coupling for connecting together electrical circuits on two substrates (7, 8). The connector assembly includes first (2) and second (3) connectors respectively attached to first and second circuit substrates. The first connector includes a plurality of first conductors (25) connected to circuits (75) on the first circuit substrate and these conductors have exposed contact surfaces with a dielectric material (4) disposed thereon. The first conductors and associated dielectric material confront second, opposing conductors (35) supported by the second connector frame when the connector frames are engaged together. A liquid dielectric material (45) is interposed between the terminals and the dielectric portions that fills minute gaps which may occur in the dielectric portions to improve the capacitive coupling ability of the connector assembly.
摘要:
A device for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band), signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components.

A kit of parts (1) comprising an electric cable (3) comprising hermetically sealed electric conductors, a connection device (5) comprising a first (9a) and a second connection part (9b), the first and second connection part each comprising a cavity (12) in which a respective secondary conduction coil (14) is arranged and connected to respective electrical contacts. In a connected arrangement of the connection device and the electric cable, the wire is wound around both the first connection part in a first winding sense and around the second connection part in a second, opposite winding sense. Thus, a watertight electric connection between the cable and the connection device is established.

Various contact systems and methods for manufacturing and using such are disclosed herein. Examples of the contact systems include a surface with one set of pads biased at a first voltage level, and another set of pads biased at a second voltage level. Such a contact system can be used, for example, to transfer power to an electromechanical device disposed thereon. In one particular example, the electromechanical device can include a power storage element and two or more couplings. When one of the couplings contacts a pad biased at the first voltage level, and another of the couplings contacts a pad biased at the second voltage level, a circuit is completed where some derivative of the differential between the first voltage level and the second voltage level is placed across the power storage element. Completion of the circuit causes the power storage element to charge. Power can be drawn from the power storage element to operate the electromechanical device.
