## Background
FIELD OF THE INVENTION
The present invention relates generally to an enclosure for telecommunication equipment, and more specifically to an enclosure system for installation over existing voice and data cabling equipment without disconnecting and re-terminating connections.
DESCRIPTION OF THE PRIOR ART
Sensitive electronic equipment for commercial buildings is typically mounted on a wall or installed in a rack or enclosure pursuant to the Telecommunications Industry Association (“TIA”) and Electronic Industries Alliance (“EIA”) standards. The TIA/EIA standards specify the minimum requirements for mounting telecommunications cabling. The telecommunications equipment includes, but is not limited to, computer network interfaces, junction boxes and other forms of voice and data cabling equipment. Electronic enclosures are typically used to limit access to electronic equipment and when security is an issue. Sometimes electronic enclosures are also installed for aesthetic purposes or for moisture protection.
There have been attempts to improve telecommunications enclosures such that the water resistance is improved. By way of example, note U.S. Pat. No. 6,527,135 to Braun et al., that discloses a water resistant enclosure providing protection to low voltage system or electronic equipment by using a three-sided removable cover and an enclosure door that covers the front opening. A shortcoming of this prior art is that to provide a retrofit installation, the existing cabling that is terminated at the equipment must be removed and re-terminated, which interrupts the service.
Another example is U.S. Pat. No. 5,568,362, to Hansson that discloses a cabinet comprised of a central casing, a door, and a partition wall defining a connector chamber inside the central casing behind the door and housing the jacks. However, Hansson is not adaptable to mount on a rack or mounting over existing electronic equipment installations.
U.S. Pat. No. 4,823,381 to Olson discloses a security cover for a conventional telephone installation backboard, characterized by use of a pair of mounting members attachable to the backboard, one of which includes a hinged door panel. A shortcoming of this prior art is that it is not adaptable to installation on either a backboard or an electronics rack thereby limiting its application. Similarly, U.S. Publication No. US 2002/0195261 to Harrison et al., discloses an enclosure, which has a back, front, and side walls, with all connections internal. However, it is limited in application.
Another example is U.S. Publication No. US 2006/0103270 to Bergesch et al., that discloses a containment bracket and enclosure for low voltage components. A shortcoming of this prior art is that it is not adaptable to enclose existing electronics installed on a backboard.
U.S. Pat. No. 4,729,614 to Nadler et al. discloses a cover for a cabinet having an exposed portion to which access can be controlled. Again, this prior art is not adaptable to different application of a backboard installation or rack installation of electronics equipment.
Notwithstanding the existence of such prior art telecommunications enclosures, there is a need for an improved enclosure that is adaptable to retrofit existing equipment and cabling installations and a telecommunications enclosure having improved security capabilities.
It is, therefore, to the effective resolution of the aforementioned problems and shortcomings of the prior art that the present invention is directed.
However, in view of the prior art at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.
