Description

ASSEMBLY OF ASSEMBLY FOR ELECTRICAL COMPLETION BLOCKS FIELD OF THE INVENTION The present invention relates to the field of connectors for communications applications and, in particular, to a assembly assembly for terminal blocks such as terminal blocks with physical connectors for fastening-indenting points. BACKGROUND OF THE INVENTION When an electrical connection must be made with a wire between two distant points, it is often not practical to use a single wire. This is especially true in the field of telephone and computer communications (data). Often, it is easier to individually wire portions of a distance between two points and then connect the portions. This is especially so, when an individual telephone is connected to the switching apparatus of the telephone company.

It would be very impractical to connect a single individual wire from the apparatus in the central switching office to an individual telephone. Therefore, a single cable is often extended from the building where the switching apparatus is located to the building where the individual telephone is located. The separate wires are laid inside the building, from the telephone to the outer cable.

Therefore, the inner cable must be connected to the outer cable. It is also possible that the outer cable is divided into smaller outer cables that need to be individually connected. In order to facilitate the connection of the inner cables to the outer cables, the terminal blocks are used. The terminal blocks are designed to make it easy to electrically connect the wires from the outer cable to the terminal block and then connect the inner wires to the terminal block so that the inner wires make the electrical connection with the corresponding outer wires. In large buildings, which have many individual telephone lines and computerized data lines, the connections between the interior lines and the exterior lines and even the connections between the lines that are vertically extended in a building, to those lines that lie horizontally in each floor, can be very large. Therefore, wiring closets are installed to contain the electrical termination blocks for the connections between the wires. Frequently, assembly assemblies are provided that can accommodate a plurality of electrical termination blocks. The mounting assembly can be mounted on a wall and include two parallel mounting means or profile rails on which the termination block is attached with mounting connectors as described in Patent Applications 08 / 279,436 and 08 / 179,360 filed at United States by the Applicant that are in cooperation and that are incorporated herein by reference. Because the assembly assembly is relatively inexpensive with respect to the terminal block and that a mounting assembly can be difficult to mount on a wall, the custom often is to use a mounting assembly that can retain a plurality of blocks of construction. termination. The mounting assembly is mounted on the wall and the termination blocks are added to the mounting assembly as needed. Electrical termination blocks come in many sizes, such as termination blocks that can accommodate 8 pairs of wires, 10 pairs of wires, 25 pairs of wires or blocks that hold 100 pairs of wires. Such different termination blocks require that the mounting rails be spaced at different distances. Therefore, different assembly assemblies are needed for different termination blocks. Also, because it is relatively difficult and it takes time to assemble a mounting assembly on a wall, it is often desirable to assemble all the assembly assemblies that may be needed over time. This has the disadvantage that a large number of assembly assemblies, for all different sizes, they must be manufactured or purchased and may never be used. OBJECTS OF THE INVENTION The object of the present invention is to overcome the problem of requiring different assembly assemblies for different sizes of termination blocks, as well as to reduce the cost of a mounting assembly to make it less expensive to buy, store and assemble assemblies of additional assembly to accommodate future expansion. The present invention achieves these objects by providing a mounting assembly that is composed of two identical brackets. The brackets are designed in such a way that they have a sliding connection. Each of the brackets has a mounting means such as a rail, and the sliding connection allows the mounting means or rails to be spaced apart from each other with the other, although the brackets are connected to each other. In this way, the assembly assembly of the present invention can be used for any size of electrical termination block. This reduces the cost since only one assembly assembly is needed for all termination block sizes. Thus, the purchase and maintenance costs of machines of different sizes and the search for parts of different size are avoided since only machinery and search of a single type of assembly assembly is needed. The two parts of the assembly assembly of the present invention are preferably substantially identical, except for those factors such as manufacturing tolerances. Since it uses a single molding component, a multicomponent assembly assembly can be produced with only the machinery and search costs required for a single assembly of components. This, then, further reduces the costs of a mounting assembly. Each bracket has a base portion and a mounting portion. The mounting portion preferably extends perpendicularly in the plane of the base, and the base is clamped to a wall. The brackets also have a sliding connection means which, preferably, is formed integrally with the base. The sliding connecting means of each bracket is formed of a first part and a second part. The first part is positioned at the first end of the base and the second part is positioned at the second end of the base. These sliding connection parts are designed in such a way that when a bracket is rotated 180 ° near the normal axis to the base, the first sliding part of a bracket is connected by sliding with the second sliding part of the second bracket. In this way, each end of the brackets are connected by sliding on the other bracket without the need for different components. Preferably, support means are incorporated in the sliding connection at predetermined distances in order to facilitate adjustment of the distance between the mounting rails for the normal size termination blocks. Link means can be provided on the end sides and on a side side of a bracket so that the brackets connected by sliding can be joined to the adjacent brackets on the end and side sides. In this way, several assembly assemblies can be mounted easily and efficiently on the wall of a wiring closet.

The present invention also includes cable carriers that can be formed integrally with the individual brackets and / or can be separate components that can be removably mounted on the brackets. The cable dies are positioned on the outer side side of the bracket and / or on the end sides of the bracket. In this way, the cables that go in the termination blocks can be positioned easily and neatly. The individual brackets also define a cable shaft opening at the base of the bracket so that the cables can enter from the back of the bracket or the portion of the bracket that is mounted on the wall. This is very beneficial when the cables enter the wiring closet from behind the wall or when the brackets are mounted on a frame such as an EIA / TIA equipment frame, preferably via a metal backing. Individual mounts are also provided with mounts or cable ties so that the cable ties can pass through these cable tie assemblies and then around the cables to securely secure the cables to the brackets. Also, each bracket contains a mounting structure for mounting an optional grounding bar on the side of the bracket. All of the aforementioned features combine to form a mounting assembly for the electrical termination blocks that are easy to manufacture and install, while being very versatile in many different situations and that have many accessories that are useful for making the connections between the separate cables. It is also an object of the present invention to provide a mounting assembly that is simple in design, rugged in construction and economical to manufacture. The various features of novelty that characterize the invention are set forth in detail in the appended claims and which form a part of this disclosure.
