Abstract:
An RF emissions shield for grounding a chassis to an associated connector mounted on a backplane includes a shield body, mounting means for securing the shield body to the backplane, and grounding means for electrically connecting the shield body to the connector. At least one spring member is integral with the shield body and is adapted to engage the chassis such that the spring member is biased against the chassis. Preferably, the at least one spring member includes a plurality of curved, resilient fingers extending from an edge of the shield body. The mounting means may include an aperture defined in the shield body, the aperture sized and configured to receive the connector such that at least an engagement portion of the shield body along the aperture engages the connector.
Abstract:
A modular connector includes at least a pair of dielectric housing modules defining at least one conductor-receiving passage therebetween. The passage is split axially whereby a passage portion is disposed in each housing module. The housing modules are plated with conductive shielding material at least in the area of the split passage. A conductor, for example, a coaxial cable section or a differential signal pair, surrouding by a dielectric sheath is disposed in the conductor-receiving passage.
Abstract:
An electrical connector for an electrical signal transmission cable having a signal conductor and a ground shield. The connector includes a one-piece housing of electrically conductive material which is folded to form first and second enclosures that are separated by a central open section. Ground contacts extend from the front edge of each enclosure into the central open section for making contact with a ground pin. A one-piece dielectric connector body holding signal contacts slides into the one-piece housing such that a signal contact is positioned within the first and second enclosures.
Abstract:
A termination structure for mating a cable connector to a circuit board has a ground terminal (150) and two signal terminals (140, 141) arranged in triangular pattern through the connector in order to reduce the impedance through the connector. The width of the ground terminal (150) increases along its extent with respect to the signal terminals (140, 141). This increase occurs along either a transition or contact portion of the ground terminal.
Abstract:
A connector which provides an interconnect between a pin and a flat conductor. The connector employs two bundles fabricated of densely packed gold plated wire for the electrical connection to the devices. The bundles are both housed in a dielectric sleeve structure and are themselves connected by a solid conductor. A portion of one wire bundle protrudes from one end of the sleeve structure to make electrical contact with a flat conductor in a mating assembly. The second wire bundle is recessed within the sleeve structure adjacent a second end of the sleeve structure. The pin is inserted into the second end in an installation, making electrical contact with the second wire bundle. The outside body of the connector is threaded, allowing an operator to twist the connector into the mating assembly, not requiring tight tolerances to ensure proper contact. The connector provides a robust electrical connection, and also provides for misalignment of the flat connector in addition to variations in the exact location of the pin. The length of the pin in the mating part can vary considerably, and the connector device still provides a controlled impedance interconnect over microwave frequencies. The connector can be installed in a larger assembly thus providing a large number of interconnections to be mating simultaneously. This is accomplished by providing clearances and tapers in the mating housing.
Abstract:
A connector made up of a plug (1900) and outlet (1800) which, when mated, define four shielded quadrants, each of which houses a pair of contacts. Shield members (1902) within the plug overlap and shield members (1802, 1804) within the outlet when mated. Overlapping the shield members at each shield member junction provides enhanced shielding and reduced crosstalk.

Said device consists of several shielding plates and at least one base rail allocated thereto. The shielding plates (2) and the base rail (3) are formed as a single piece of sheet metal (28) and each shielding plate (2) is connected to the base rail (3) via a narrow segment (4) and is arranged at the base rail (3) being pivoted by 90 DEG in relation thereto, in order to simplify the assembly of the screening device inside said strip terminal.
Abstract:
The invention relates to an insulator for an electrical conductor provided with an outer shield, especially a so-called coaxial cable or shielded twin cable, in order to achieve an insulation at the shield that insulates against DC and low frequency AC signals transforming through the conductor and that includes a first and a second element (3, 4) formed from electrically conducting material that by means of a dielectric (5) are electrically insulated and delineated from one another and that are intended to be connected between an interruption at the shield or between the shield and an external earth connection. To achieve an insulator of the type that uses a standard type of capacitive element and that is simple and cheap to produce at the same time as it only has small dimensions, the elements (3, 4) are, according to the invention, arranged with one or several continuous openings running through them for passing the conductor through the elements and that the delineation between the elements defined by means of the dielectric (5) is crossed by one or more discrete capacitive elements (6) that are electrically connected between the first and second elements.

The invention relates to a contacting unit for a card-shaped carrying element of electronic modules, especially according to PCMCIA standards, comprising a plug-in card-shaped housing (2) which has a base plate (3) and a cover plate (6) that is congruent in at least a transverse direction. A slot-like plug-in channel (8) which opens on a face of the housing (2) and which is provided for accommodating a chip card (9) is configured between the base plate and the cover plate. In addition, said housing is provided with a plug-in connector strip (4) on the face opposite the chip card. The contacting unit also comprises a printed board (7) which is arranged parallel to the plug-in channel (8) in the housing (2) and which is electrically connected to the plug-in connector strip (4). Said printed board is provided, on the surface thereof, with a contact field for contacting the chip card (9). The plug-in channel (8) is continuously open on both sides over the entire length thereof in the direction in which the chip card (9) is plugged in. In addition, the base plate (3) and the cover plate (6) are exclusively joined to one another in a tight manner in the area which connects to the plug-in channel (8) in a plug-in direction.
