Abstract: A protection cap for an electrical connector with several terminals extending from a first end thereof. The cap includes a body having a cavity for releaseably receiving a second end of the connector which is opposite the first end, at least one arm extending from the body for wrapping partially around the connector, and a terminal retainer arranged on the free end of the arm for engaging at least some of the terminals.

Abstract: A backplane assembly for a line replaceable module enclosure or rack includes an electrical backplane and a fiber optic backplane separately attachable to a single frame. The frame serves as a common datum for the electrical and fiber optic backplanes, and includes integral mating interface features for enabling line replaceable module connectors having a common shell to mate with the separate electrical and fiber optic connector structures on the backplane. The optical backplane is a one-piece structure to which pairs of individual fiber optic connectors, including input/output connectors, may be directly secured via a simple retention plate arrangement, the fiber optic connectors all having the same orientation to enable direct routing of fiber ribbons between rows of connectors serving different line replaceable modules.

Abstract: A circuit board module includes a plurality of high density edge connectors in which the contacts are arranged in rows, with contact tails extending from the connectors for electrical connection to a circuit board carrying electrical components. Instead of terminating the contacts directly to pads or terminals on the principal surface of the circuit board on which the electrical components are situated, however, the contact tails are terminated to pads or terminals on pairs of intermediate circuit boards connected to the main boards, the intermediate circuit boards each providing two termination surfaces rather than one, thereby effectively doubling the space available for termination. The intermediate circuit boards are connected to the main circuit board by a rigid-flex interconnection, thus facilitating assembly of the connectors to a heatsink or frame of the circuit board following termination of the contact tails to the intermediate circuit boards.

Abstract: A device for assisting in and maintaining erection of the human penis, comprising: a relatively rigid arc member and an elastic cord extending from each end of the arc member and joined to form a large loop.
