Abstract
MOUNTING BASE FOR ELECTRICAL CIRCUIT BLOCKS
Abstract of the Disclosure A mounting base for securing electrical circuit blocks to the wall of a building comprising a generally rectangular base having side walls which extend upwardly a predetermined distance from substantially the entire periphery of the rectan-gular base. The base and block are attached to a wall of the building by screws which may be inserted from face of block through bushings provided on two of the walls of the base. An electrical circuit block having electrical connectors which have wire-wrap tails protruding therefrom is secured to the base by screws which fit within bushings provided along two walls of the mounting base. The base according to the present invention will completely protect the wire-wrap tails of elec-trical circuit blocks from being shorted out by paper clips, water, and other debris. The base also protects wired tails of previously wired circuit blocks from being contacted or short circuited when additional circuit blocks are mounted in the vicinity of the previously wired circuit blocks. In order to more fully insulate the wire-wrap tails of the circuit block, an insulating compound may be injected into and seal the space between the circuit block and the mounting base when the circuit block is used in corrosive or high humidity locations.

Description
M.OUNrrING Bi~SE FOR ELECTRIC~L CIRCUIT BLOCKS
Background of the Invention (1) Field of the Invention The present invention relates to the mounting of cir-cuit blocks having electrical connectors which have wire-wrap tails protruding rom the bottom surface o the block. More specifically, the present invention relates to mounting bases for mounting such circuit blocks to a wall to provide for insul-ation of the protruding electrical connectors from the external environment and to provide a self-extinguishing mounting base.
(1) Description of the Prior Art In large buildings such as office buildings and resi-dential buildings, a large number of telephones are installed.
Part of the equipment used in installing the telephones are elec-trical circuit blocks which allow connection of various electri-cal circuits on a single block. Typically, one surface of the electrical circuit block has a series of electrical connectors which protrude from the surface. The connectors are interconnec-ted by wires which may be simple insulated wires or which may also be diodes or resistors.
The electrical circuit block having conductive wires protruding therefrom is mounted to the wall of a building by the use of brackets. However, there exists a significant drawback to mounting the electrical circuit blocks to the wall of a build ~5 ing with open mounting brackets. By using brackets, a space is provided between the wall of the building and the protruding elec-trical connectors. Debris such as paper clips, water and the like may come into contact with the electrical connectors of the blocks and cause undesirable short circuiting between the connectors. In--~0 stallers may also accidentally short circuit the connectors.
~3~
Thus, it is one object oE the present invention to provide a mounting base which insulates the protruding elec-trical connectors of the block from the debris which may be present in the environment surrounding the block.
It is another ob]ect of the present invention to pro-vide a mounting base which allows for easy attachment of the base and bloc]c to the wall of the building as a single unit.
It i5 a furthex object of the present invention to pro-vide a mounting base which allows ~or electrical insulating mat-erial such as "gun]~" to be interposed between the electrical cir-cuit bloc]c and the mounting base to seal the electrical connec-tors protruding from the electrical circuit block from the exter-nal environment. It is a further object of the present invention to provide a self-extinguishing mounting base and block so that the presently used fire-retardant back boards can be eliminated.
Summary of the Invention The present invention provides a mounting base for elec-trical circuit blocks which have electrical connectors protruding therefrom. The mounting base functions to separate the electrical connectors of the electrical circuit block from the environment external to the mounting base in order to reduce or eliminate the possibility of short circuiting of the electrical connectors due to debris being placed accidentally between the connectors. The mounting base comprises a generally rectangular floor having side walls extending upwardly therefrom around substantially the entire perimeter of the rectangular floor. The walls extend upwardly a predetermined distance so as to shield the electrical connectors of an electrical circuit block mounted on the mounting base. Two of the walls of the mounting base include bushings for screws which hold the mounting base and block to the wall of the building.
A second two walls include bushings which provide for screws which mount the electrical circuit block to the mounting base.
When the electrical circuit block is mounted to the mounting base, the protruding electrical connectors of the circuit block are separated spatially, that is, insulated from the environment external to the mounting base so that debris such as paper clips and water does not short circuit the electrical connectors on the - , ~
1~L37;~'1 blocks and the wire-wrap tails are protected from physical damage. Moreover, the above described structure allows for the use of an insulating material such as, for example, "gunk" which may be interposed between the circuit block and the mounting base to seal the electrical connectors of the circuit block from the environment external to the base. Because the electrical connectors of the circuit block are sealed, should a fire begin within the mounting base, the fire will be extinguished for lack of air.
According to a further broad aspect of the present invention, there is provided a mounting base for securing an electrical connector to a surface comprising:
an imperforate planar floor, said floor having a peripheral edge and being of generally rectangular shape;
two pair of oppositely disposed side walls extending transversely outwardly from the said edge of said floor in a first direction, the side walls of each pair being parallel, said walls being integral with said floor to thereby define a region above said floor for receiving conductor elements extending from a connector, said floor and side walls being formed of a material which is impervious to fluid whereby said region is isolated from the conditions to which the side of said floor which face~ in a second direction opposite to said first direction is exposed, the outwardly disposed edges of said side walls lying in a common plane which is parallel to said floor;
means for securing said mounting base to a supporting surface, said securing means including a first apertured pro-trusion extending from each of the walls of a first pair of said parallel side walls into the said region defined by said side walls and floor, said first protrusions being integral with said side walls of said first pair and with said floor and extending from the plane defined by the outwardly disposed edges of said walls to said floor, the apertures in said first protrusions extending through said floor to said plane within - the protrusions;
