The object of the invention is to construct a simple packaging structure having few components and capable of protecting a contained product against shock impacts coming from all directions. To this end, the packaging structure according to the present invention is made of synthetic resin with an elastic quality molded into a sheet form, and includes a first tray pack and a second tray pack which face each other and are adjoined to hold the contained product securely in place; wherein the first and second tray packs are provided with sustaining portions sustaining the periphery of the contained product.

Tray pack and packaging structure

A communication device includes a sub-rack unit and a plurality of plug-in units. The sub-rack unit includes a back wiring board having first connectors arranged in lines thereon, and a frame plate including vertical ribs and placed on said back wiring board so that the vertical ribs separate the lines of the first connectors. Each of the plug-in units includes: a printed board including top and bottom sides and parallel first and second sides, the printed board having second connectors provided on the first side thereof; a metal case including top and bottom faces, and parallel first and second side faces so as to cover the printed board; and first and second spring members. Each of said plug-in units is mounted in the sub-rack unit with the first and second connectors being connected so that the first and second side faces of the metal case are pressed outward against the vertical ribs of the frame plate by resilient forces of the first and second spring members, respectively.

Communication device and plug-in unit therefor

In a mechanism for inserting and removing electronic circuit units against a shelf of an electrical device where the electronic circuit units are installed, the shelf includes a groove forming part, the electrical circuit unit includes a rotatable lever, a rotatable stopper, and a housing member, and the electrical circuit unit is locked with the shelf by rotating the lever.

Mechanism for inserting and removing electronic circuit unit

An optical unit includes photoelectric conversion modules, a plurality of adapter support members whose upper parts are rotatably supported, and a plurality of optical connector adapters attached to lower ends of the adapter support members so as to be arranged next to each other, the optical connector adapters being contained in the optical unit. The adapter support members are rotated separately so that the optical connector adapters are extracted outside from the optical unit with a space formed between each adjacent two of said optical connector adapters. Each of the optical connector adapters has insertion holes to which optical connectors of optical fibers extending from the photoelectric conversion modules and optical connectors of external optical fibers are connected.

Optical unit with increased reliability

An optical telecommunication unit includes a shielded case having a size adapted for mounting upon a standard open-rack frame, wherein the shielded case includes a rear panel carrying an interconnection pattern, a plurality of plug-in connectors provided on the rear panel at an inner side thereof in electrical connection with the interconnection pattern for holding plug-in units forming an optical telecommunication apparatus inside the optical telecommunication unit, wherein the optical telecommunication unit carries a plurality of interface connectors on the rear panel in electrical connection with the interconnection pattern for accepting external interconnection cables, and a rear cover is provided on the shielded case so as to cover the rear panel.

Optical telecommunication apparatus for use in an optical ring network

A case unit for housing printed-circuit assemblies includes a top plate made of metal, a bottom plate, made of metal, facing the top plate, side plates facing each other, the side plates being positioned between side portions of the top plate and the bottom plate so that a space surrounded by the top plate, the bottom plate and the side plates is formed, and guide rails, made of resin, integrated with the top plate and the bottom plate, the guide rails guiding the printed-circuit assemblies loaded into the space. Each of guide rails integrated with at least one of the top plate and the bottom plate has a guide rail body for guiding an edge of a printed-circuit assembly, the guide rail body being provided on an inner surface of a corresponding plate which is the top plate or the bottom plate, a flat member provided on an outer surface of the corresponding plate, and connecting portions occupying mounting holes formed through the corresponding plate, the connecting portions connecting the guide rail body and the flat member, so that the guide rail body is fixed on the corresponding plate by the connecting portions and the flat member.
