  • Patent number: 7118414
    Abstract: A computer input/output connector assembly which uses connector port holders that can easily be snapped into a metal retaining bracket. In one preferred embodiment, the bracket of the present invention is mounted on the front of a personal computer tower. Connected to the bracket is a first connector port holder with two USB connector ports, a second connector port holder with an IEEE 1394 high speed communication port, a third connector port holder with three audio ports (e.g., audio in, audio out and microphone) and a fourth connector port holder with two video ports (e.g., RCA composite video and S-video). The connector port holder is preferably made of a durable, heat resistant plastic. This connector port holder includes movable cantilever strips with lock tabs which can firmly snap into holes in the bracket for mounting.

  • Patent number: 5702263
    Abstract: A system for releasably locking and unlocking a connector and backshell combination for supporting conductors that extend from the connector includes a threaded clamping ring in an assembly having facing first and second detent rings that are formed with respective multiplicities of mating detent members. The first detent ring is angularly fixed relative to the clamping ring; the second detent ring is affixed to or integral with a flange ring that is affixed to a body of the backshell. The backshell body can have an enlargement such as for a conductor clamp, in which case the detent ring is affixable subsequent to location of at least the first detent ring between the flange ring and the enlargement when the enlargement would block assembly from that direction. A nested plurality of cone-shaped spring washer axially holds the detent rings in facing engagement, whereby a total surface contacting area of engagement between the detent members is at least 0.
