DESCRIPTION:
BRIEF SUMMARY
The present invention relates to connectors and in particular to a wall mounting system for data communications connectors.
The proliferation of data processing and communication devices over recent years has necessitated the installation of extensive wiring in buildings housing users for such equipment. Typically a central processing unit may be located in one position on one floor of a large building whereas persons using information from the unit or keying in information to the unit may be located on another floor of the building or at a position on the same floor somewhat removed from the unit. The various components comprising a data communication system are traditionally linked by complex wiring systems and in order to facilitate the servicing of independent components of such systems and to maintain the versatility of such a system a number types of connectors are used to plug one component of the system into wiring in communication with other components of the system.
Typically the wiring for such systems may be concealed within walls, within skirting boards or even surface-mounted on a wall, ceiling or floor. Typically cover plates of the type used in relation to conventional electric plug points and light switches are utilised to locate one-half of a male/female plug system; the other half of the system being a "flying" lead.
Such cover plates are not entirely adequate for a number of reasons the first being that they result in a connector protruding from the wall or mounting surface with the wiring at ninety degrees from the wall. Such a system is wasteful of space and exposes the connectors to damage by cleaning equipment or other movement adjacent the cover plate.
It is additionally the case that a number of different types of connectors are used in relation to data communication equipment ranging from BNC type co-axial connectors to 5, 9, 15 or 25 pin D type connectors.
Conventional "plug point" type cover plates are provided with a number of different shape cut-outs to accommodate such differing connectors. Such cover plates are additionally provided with hardware in the nature of threaded "hex posts" in order to fix the peripheral flanges of female connectors to the peripheral flanges of corresponding male connectors in a satisfactory spaced relationship such that the male and female plugs may be securely, although removably united. Such hardware is expensive as it does not form part of the plastic cover plates and it is furthermore expensive to provide cover plates having differing cut-outs to suit differing connectors.
The present invention seeks to ameliorate one or more of the abovementioned disadvantages with existing data communications mounting plates or at least to provide the consumer with a choice.
According to the present invention there is provided a mounting system for data communications connectors comprising a body portion formed as a substantially rectangular frame defining a central void; the frame having a depth not less than the depth of a flange of a standard 25 pin D type connector; at least one end of a frame, when viewed in elevation, displaying a wide substantially U-shaped cut-out open to the upper surface of the frame; guide means on each of the two opposing sides of the U-shaped cut-adapted to releasably receive and guide the flange of a connector or a peripheral portion of an adaptor plate slidably introduced from the open end of the U-shaped cut-out, the guide means serving to locate the flange of the connector or the adaptor plate so as to fill in the "U" shaped cut-out while preventing movement with respect to the frame perpendicular to the direction along which such articles are slidably introduced into the frame; a cover plate for the upper surface of the frame such cover plate extending at least in part over an area above the guide means such that once the flange of a connector or an adaptor plate is introduced into the frame and the cover plate is in place the connector or adaptor plate is captive within the frame/cover plate system; means to facilitate fi
