Abstract:
A connector module for mounting on a circuit board includes a housing and at least one plug-receiving opening for receiving an RJ-45 or other similar jack. Each plug-receiving opening includes contact portions that make electrical contact with individual conductors, e.g., twisted pair conductors, connected to the RJ-45 jack. A plurality of connection pins protrude from a bottom surface of the housing and facilitate mounting of the modular connector onto the circuit board. Protection/filtering circuitry, located within vertical space inside of the housing so as to reside adjacent the connection pins, electrically couples and minimizes the electrical distance between the contact portions associated with each plug-receiving opening and the plurality of connection pins. The protection/filtering circuitry includes at least one ring-shaped ferrite core. Light emitting diodes may also be included as an integral part of the module, but are mounted for viewing so as to be outside of the shielded portions of the module.
Abstract:
Either of a pair of adjacent plug holes in a computer network hub is automatically closed by a swinging door plate whenever a connector of a signal line is inserted into the other plug hole to prevent the simultaneous insertion of two connectors into both plug holes.
Abstract:
Connector (10) includes a shell (14) having a forward end (18) exposing a mating face of an insulative housing (12) for mating. Shell (14) is stamped and formed from a blank to define four walls surrounding the housing upon assembly, with an open seam (88) defined in one of the walls by opposed edges of the blank. Tabs (60) of the shell adjacent the one wall extend toward each other from edges of the adjacent shell walls, and include end portions bent inwardly toward the housing to be seated within slots (62) in the housing, holding the adjacent shell walls against the housing and preventing inadvertent opening of the seam (88).
Abstract:
An auto-termination network cable connector which includes an auxiliary connector for connection to network cable, a main connector for connection to workstation computer, and coaxial cables connected between the auxiliary connector and the main connector, wherein the auxiliary connector has a resistor of predetermined impedance at the center and a metal spring plate at each end to automatically form a terminator at each end upon the removal of the BNC plug therefrom; a metal shield is installed in the auxiliary connector surrounding the resistor, the central terminal of the auxiliary connector, and the central conductors of the coaxial cable to protect against electromagnetic interference.
Abstract:
A zone distribution adapter 2 for use as a breakout or tap with twisted pair cables provides a compact configuration that can be employed as a standalone component with a cover 22 enclosing a printed circuit board assembly, or the printed circuit board assembly can be mounted in standard distribution boxes or beneath a low profile access floor. The preferred embodiments of the zone adapter printed circuit board assembly includes a twenty-five pair vertical mount electrical connector 12 soldered to a printed circuit board 8 with four-pair electrical connectors, such as right angle modular jacks 16 or punchdown blocks 20 soldered on the sides of the twenty-five pair connector. Printed circuit board traces 10 connect corresponding positions in the twenty-five pair connector 12 and the four-pair connectors 16, 20. The cover 22 includes a central channel 26 between two raised side sections 28 with an opening 24 through which the mating portion 14 of the twenty-five pair connector extends. Twenty-five pair cable connectors 42 mated to the vertical mount printed circuit board connector 12 are thus positioned on the outside of the cover 22 so that the zone adapter retains a low profile which permitting the use of different cable connector configurations.
Abstract:
The invention concerns a carrier arrangement (10) comprising a longitudinal column-type carrier (15), whereby a coupling arrangement is provided to establish a mechanical and simultaneously electrical connection to a medical apparatus (40). The coupling arrangement comprises two guide rails (20, 30) which are electrically insulated against each other and extend along the entire length of the carrier (15).
Abstract:
A modular jack for a 10BASE-T standard Ethernet-type local area network connection to a printed circuit board edge includes a body portion, a plug receptacle, a PC board mounting apparatus, and a cavity for receiving a LED to indicate the status of the LAN connection. The LED preferably is embedded in the front face of the body portion of the jack. Alternatively, the body portion of the jack may be molded from a transparent or a translucent resin, and the cavity may be formed in the underside of the body portion, whereby the LED may be mounted on the PC board and the jack inserted on the PC board over the LED, with the body portion of the jack conducting light from the LED to the front face of the jask.
Abstract:
An electrical connector component assembly (10) provides for shielding as between components of the connector. An electrically conductive outer housing (12) includes a plurality of discrete bounded compartments (30). A plurality of electrically insulative terminal support elements (14, 16) are supported individually in the bounded compartments. Plural electrical contacts are supported in at least one of the support elements. The electrical contacts supported in the one support element are electrically shielded from the components of the other support element by the bounded compartments. The electrical connector component assembly (10) may be interconnected to an identical connector in hermaphroditic fashion such that mating contact surfaces (74) engage one another locking the contact to the like contact.
Abstract:
An electrical shielded data connector includes an inner terminal support housing (4, 404, 520) carrying a plurality of electrical terminals such as (30, 560) where the terminal support housing includes shield members (130, 160; 330, 360; 460; 516, 518) surrounding the terminal support housing (4, 404,520). The shielded sub-assembly is insertable into an outer housing (70; 512, 514) and is latchably attached therein and a rear support plate (95) and cable support member (110) can be assembled around a cable after the termination of the multi-conductor cable. The cable support member (110) can be positioned in one of two orientations to provide for either a straight through or an angled cable exit. A cross talk shield (200, 524) is positioned in a stuffer cap (180, 522) and is situated between adjacent terminals (30, 560) when in the final position. Another cross talk shield (220, 320) is positioned in a slot (50, 450) intermediate the terminals (30) at the lower side thereof.
Abstract:
A data bus coupler includes a plated composite housing and a plurality of twin axial contacts, the shielding portions of each contact being connected to the housing by a conductive insert which serves to retain the contacts in the connector. The coupler also includes a printed circuit board carrying transformers and isolation resistors for providing stub connections to a data bus line.
