Abstract:
A shroud that forms a guide channel for a connector is disclosed and it has the shape of an inverted U-shape, with a press tab for engaging a mating connector. The shroud has notches and tabs formed on it that serve to orient the mating connector for entry into the shroud. A placement member is also described and it serves to hold the connector and the shroud together as a single unit for robotic placement of the shroud and connector in preselected positions on the circuit board.
Abstract:
A plug connector is disclosed that has a body portion and a circuit card extending forwardly of a mating face of the connector. The circuit card is protected in place by a pair of protective flanges that extend forwardly from the body portion and which flank the circuit card to protect it from stubbing and to provide a first means for aligning the plug connector with the receptacle connector. One or more projections formed on the exterior of the plug connector provide second means for aligning the plug connector with the receptacle connector.
Abstract:
A connector assembly for connecting differential signal circuits on two different circuit boards has a connector housing formed from an insulative material with a conductive coating on the surfaces thereof and with cavities formed therein to receive terminal assemblies. Each internal cavity may have an elongated portion that extends transversely across the housing and a plurality of leg portions in communication with the elongated portion to define passages between opposite sides of the connector. Each cavity is suited for holding a terminal assembly having at least one pair of differential signal terminals. The terminals have opposing compliant tail portions, and interconnecting portions that are partially encapsulated by an insulative outer shell. Two shells are combined together to form a single terminal assembly. The terminal assemblies are identical in shape so that they may be inserted into any of the cavities of the housings, thereby imparting a measure of modularity to the connectors.
Abstract:
A connector assembly is provided with opposing and interengageable first and second connector components. Each of the two components preferably includes upper and lower housing formed from an insulative material, with cavities formed therein that receive terminal assemblies. The upper and lower housings are formed with internal cavities that extend in different directions. These cavities are aligned together when the upper and lower housings are assembled together to define a plurality of internal cavities that extend through the first and second connector components. Each cavity contains a terminal assembly with differential signal terminals. The terminals have contact portions, tail portions and interconnecting portions that are partially encapsulated by an insulative outer shell. The exterior surfaces of the connector components are plated with a conductive material so that the connector components serve as grounds for the differential signal terminals.

Abstract:
A card edge connector assembly is adapted for receiving a printed circuit card having an insertion edge insertable into and removable from the connector assembly. The assembly includes an elongated dielectric housing having a card-receiving slot. A lever is pivotally mounted on the housing near an end of the slot. The lever includes a front face, a latch portion extending forwardly of the front face for engaging a notch in a side edge of the card, an ejector portion extending rearwardly of the front face for engaging the insertion edge of the circuit card at a corner thereof and ejecting the card from the slot in response to pivoting of the lever. A limiting portion limits longitudinal movement of a side edge of the card when the card is in the slot. A hollow area is provided between the ejector portion and the limiting portion for receiving the corner of the card when the lever is pivoted and the card is ejected.
Abstract:
An IC card includes a generally rectangular frame. A circuit board assembly is mounted on the frame, with the circuit board assembly including a generally planar dielectric substrate having circuit traces and at least one electrical component mounted thereon. A receptacle connector including terminals is mounted at an edge of the circuit board assembly, with the terminals being adapted to mechanically and electrically engage the circuit traces on the circuit board assembly. Complementary interengaging latches are provided between the frame and the receptable connector for securing the receptacle connector at the edge of the circuit board assembly and for ensuring a mechanical and electrical connection between the terminals and the circuit traces on the circuit board assembly. The invention also contemplates a method of fabricating the IC card according to the above.
Abstract:
A thermoelectric cooler that includes a hot side thermally conducting/electrically insulating cover plate with electrical connectors on the inner surface, a cold side thermally conducting/electrically insulating cover plate, the hot side thermally conducting/electrically insulating cover plate being displaced away from the cold side thermally conducting/electrically insulating cover plate with electrical connectors on the inner surface, one or more thermoelectric elements, each thermoelectric element comprising a p-doped semiconductor element and an n-doped semiconductor element, each one of the p-doped semiconductor element and the n-doped semiconductor element being disposed between the hot side thermally conducting/electrically insulating cover plate and the cold side thermally cover plate, and means for improving thermal conductance to the hot side thermally conducting/electrically insulating cover plate.
Abstract:
A connector includes a cage that has two side walls, a top cover and a rear wall that are combined to form a hollow enclosure. The enclosure is separated into two module-receiving bays by at least one spacer with a top and bottom wall that extends between the sidewalls to form a central portion between a top and bottom bay, the central portion acting as an air passage between a front face and the sides of the connectors. Air openings are formed in the sidewalls of the cage assembly and they communicate with the central portion. The bottom wall of the spacer is provided with a large opening that extends a substantial distance of module-receiving bay and provides an air flow path from the air openings to the bottom module-receiving bay. An insert with apertures in communication with the central portion can be positioned.
Abstract:
A connector utilizes a latching assembly that has a structure that connects horizontal movement of an actuator to vertical movement of a latching arm. If desired, a 2X ganged plug can be inserted into any two adjacent bays of a ganged receptacle assembly that includes at least three bays.
