Filed:

Mar 20, 2000

Appl. No.:

09/528500

Inventors:

David Oliphant - Salt Lake City UT 84120
Thomas A. Johnson - Draper UT 84020
Brent D. Madsen - Providence UT 84332

International Classification:

H01R 1700

US Classification:

439660, 439 62, 439676, 439946, 439354

Abstract:

A communications card allows computers to be electrically connected to electronic devices and communications systems. The communications card includes a modular jack with a plurality of contact pins. The contact pins include a plug engaging portion that does not include any sections that are angled more than about 90° in order to minimize the stresses in the contact pins. The contact pins also include a connector portion that allows the contact pins to be electrically connected to a printed circuit board disposed within the communications card. Preferably, the plug engaging portion includes an elongated arm that aids in absorbing stress and deflection of the contact pins. Advantageously, the contact pins are designed to minimize the height of the modular jack such that the modular jack can be used with communications cards that comply with the PCMCIA Type III standards.

International Classification:

H01R 1200

US Classification:

439 761, 361737

Abstract:

A computer card assembly for removeable insertion into a receiving/expansion slot of a host computer is presented. The computer card assembly facilitates the removal and recombination of at least one electronic card in an electronic card interface tray that includes a shared interface. An electronic card interface tray includes an external shared interface that can facilitate larger jacks and opposing sidewalls which together form bays or slots within the computer card assembly. The electronic card is sized to be received within a bay of the card tray to facilitate insertion of the computer card assembly into the host expansion slot. The electronic card supports the standard host interface while sharing and external interface, such as a network interface, with other cards within the computer card assembly.

Assignee:

3Com Corporation - Santa Clara CA

International Classification:

H01R 909

US Classification:

439131, 439676, 439329

Abstract:

A modular jack, for coupling with a physical/electrical media plug, comprises a frame, a rocker arm, electrical contacts, and a retractable cover guard for protecting the electrical contacts during nonuse. The retractable cover guard moves from a protective position to a retracted position when a physical/electrical media plug is inserted into the modular jack and returns to the protective position when the physical/electrical media plug is removed. While only a shallow insertion depth of the physical/electrical media plug is permitted, the rocker arm aligns and mechanically secures the physical/electrical media plug within the modular jack.

International Classification:

H05K 114

US Classification:

361737, 361736, 361752, 439 761, 439490

Abstract:

An electrical jack system is operable with an electrical plug, such as an RJ-type plug. In one embodiment, the electrical plug is at least partially translucent. The jack system includes a housing bounding a socket. The socket is configured to receive the electrical plug. A light source is coupled with the housing so as to selectively illuminate the socket and/or the translucent electrical plug when the translucent electrical plug is received within the socket of the housing. In one embodiment, the light source is a light emitter, such as an LED, mounted on the housing so as to be at least partially exposed to the socket of the housing. In an alternative embodiment, an opening is formed on the housing in communication with the socket. A light emitter is disposed a distance from the opening on the housing. A conduit extends between the light emitter and the opening.

International Classification:

H01Q 138

US Classification:

343702, 343700 MS

Abstract:

The present invention is a retractable/extendable diversity antenna that provides the appropriate polarization in a horizontal orientation. The antenna structure is placed within a Type II PCMCIA PC card package and may be extended or retracted with one touch. The antenna structure is large enough to provide for the diversity antenna design and may optionally be housed within a PCMCIA Type II PC Card. At least one spring-loaded mechanism is used to extend the antenna structure beyond the PCMCIA PC Card package and to provide stability while the antenna structure is in the extended position. The diversity antenna configuration may consist of either two miniature, planar antenna modules or two etched printed circuit board contours that are spaced as far apart as possible with a minimum separation of a quarter wave length distance in order to provide mitigation to radio multipath fading effects. The antenna modules have orientations perpendicular to each other such that the polar nulls representative of their radiation patterns remain spatially orthogonal.

US Classification:

174 66, 174 67, 220241

Abstract:

A system is disclosed for mounting a faceplate. The system includes a sub-plate configured to be coupled to a junction box. The sub-plate can have an interference-fit socket extending through the sub-plate. The interference-fit socket includes one or more interference fingers located adjacent to a post opening. A post extending from the faceplate can be positioned and sized such that, as the faceplate is coupled to the sub-plate, the post will be received into the post opening in the interference-fit socket and engaged by the one or more interference fingers, enabling the faceplate to be securely mounted to the sub-plate.
