Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the distribution cabling of electrical
current in electrical apparatus. It thus concerns the connection
and routing of electrical wiring about the apparatus.
Generally such cabling and connection systems utilize multiple pin
and socket connectors, particularly rack and panel types and these
connectors have been used for many years to make electrical
connections to the unit, module or other apparatus.
In the past, commercial electrical connectors generally were used
to connect or disconnect a circuit with ease of installation and
removal. These connectors usually had equal pluralities of
terminals in the male and female portions of the connector.
Consequently it was very awkward and expensive to create more than
one wire leaving the connector for a single wire entering it.
One of the advantages of using multiple pin connectors is the speed
and ease with which the electrical connections can be made or
broken and apparatus removed from a parent system for service
and/or changes. A system can also be broken down into various
components for ease in shipping and then quickly reassembled and
reconnected. Another advantage of such connectors is that a harness
can be made separately from the wiring of the system for
interconnection within and between multiple modules. This harness
can be constructed more easily on a form board, or similar method,
apart from the parent system.
2. Description of the Prior Art
As previously noted, prior art connectors had a major disadvantage
in that only one circuit could be made through any one pin and
socket combination. In order to make multiple connections to
several modules, such as a common supply line feeding several
modules, it previously has been necessary to bring the supply lines
to binding posts on terminal boards. Thereafter, multiple single
leads were brought out from this common supply on the terminal
boards to the various modules. This, in turn, meant that a system
having requirements for such multiple circuits could not be
completely "plug in." The harness must have different types of wire
terminals, such as for example, spade lugs, etc. for use on the
terminal board binding posts. Thus to assemble the system after a
prior disassembly for shipment, the connections must be made
individually to the terminal board binding posts. This type of
reassembly of course brings with it the possibility of making
incorrect connections. It is possible in some cases to incorporate
the terminal blocks into the harness, but when the blocks are large
or the mounting position is such that the fastening means are
inaccessible, this solution is not feasible.
BRIEF SUMMARY OF THE INVENTION
The purpose of this invention is to provide means of making common
connections to several modules, utilizing connectors similar to the
connectors usually incorporated in such systems. Thus instead of
going to a terminal block to create the additional lines from the
common supply, as was previously done, the wire is merely connected
to another identical connector hereafter called the distributor or
jumper connector, and a plurality of wires are returned from this
connector to the cable. A jumper is inserted into a portion of this
identical connector body to provide as many additional wires from a
common supply as is desired.
It is therefore an object of the present invention to provide an
electrical distribution connector for use in a cabling assembly for
electrical apparatus which is capable of providing a plurality of
output terminal contacts for an individual input terminal
contact.
It is also an object of this invention to provide an electrical
connector wherein one or more feed and source distribution
connections may be made through one side of the connector.
It is still a further object of the present invention to provide an
electrical connector wherein one or more jumpers are inserted in
one portion of the shell of the connector and all of the
distribution circuit wiring is accomplished through the second
portion of the connector shell.
It is also an object of the present invention to accomplish these
aforementioned objectives through the compatible use of presently
available commercial connectors.
A still further object of this invention is to provide an
electrical distribution system having a plurality of electrical
connectors, including said jumper means, which system is entirely
"plug in."
It is still a further object to provide an electrical wiring
distribution system which system may be preconstructed upon a form
board or some similar "jig" type means.
These and other objects will become more readily apparent upon
consideration of the remainder of this specification together with
the accompanying drawings. A specific embodiment which the inventor
considers to be the preferred one is set forth in the following
detailed description .
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an isometric illustration showing the overall
configuration of the suggested embodiment;
FIG. 2 is an exploded isometric view of the distribution
connector;
FIG. 3 is a partial, cut away, isometrical view of the
connector;
FIG. 4 is an isometric view of the jumper means used in the
distribution connector.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 illustrates the electrical distribution connector and the
switch connector in the overall distribution system. It is readily
seen that it is utilized to provide a plurality of output wiring
connections 1-20, 1-22, 1-24, 1-26 and 1-28 for each input wire
1-18 connected to it. Thus the distribution connector shell has a
first 1-14 and a second 1-16 portion. In the present scheme, the
female portion of the connector is included in the second portion
1-16 of the shell, while the male portion is created in the first
shell portion 1-14 by the insertion in the shell of the jumper. The
distribution connector also may be said to have a fixed portion
1-14 mounted, for example, to a module housing, and it also has a
removable portion 1-16 which is permanently wired into the cabling
of the distribution system. In FIG. 1, for illustrative purposes,
the two connectors are shown mounted to a base plate 1-1. More
specifically, the fixed members 1-10 and 1-14 of the two connectors
are mounted to the base plate 1-1 via a pair of insulative bases
1-2 and 1-4 respectively. When it is desired to remove the cabling
from the system for repair, servicing of the module or for
dismantling the system for shipment, the cabling can be almost
instantaneously unplugged. Conversely when the system is being
reconstructed the cabling can be speedily installed. It bears
repeating that this installation is not only rapid but foolproof,
as well, in that the proper wire must go to the correct
connection.
The remaining connector (herein called the switch connector) also
has a fixed portion 1-10 and a removable portion 1-12 for ready
installation and removal. However, in this connector although a
multiplicity of wires 1-30, 1-32, 1-34, 1-36 and 1-38 are connected
simultaneously, only a single wire in the fixed portion of the
connector goes to a single wire in the removable portion.
From the removable portion of this switch connector selected wires
may be separated from the cable and wired to the distribution
connector. One of these selected wires 1-18 enters the movable
portion 1-16 of the distribution connector for connection to the
jumper inserted in the fixed portion. From this jumper shown in
detail in FIG. 4 five additional fingers enter the fixed portion
1-14 of the connector to provide five additional common connections
to the single wire entering the movable portion. These five wires
1-20, 1-22,1-24,1-26 and 1-28 thereafter leave the distribution
connector and reenter the cable. Thus at this point five wires are
now in the cable for each selected original one 1-18. It is readily
seen that a plurality of these jumpers can be used in the
distribution connector to provide almost any combination of wire
pluralities.
This, of course, is a vast improvement over the prior art method of
having each wire leave the cable and enter a terminal block from
which a plurality of common leads had to be derived. The advantages
are obvious; ease of installation and removal, lack of mistakes due
to rewiring of the terminal block after each disassembly and the
capability of prewiring the entire cable on a separate "jig" or
form board.
FIG. 2 illustrates a plurality of such jumpers 2-50 and 2-52
inserted through the fixed portion 2-14 of the distribution
connector. The fixed portion 2-14 is mounted, in turn, to an
insulative base 2-2. As indicated, these inserted jumpers 2-50 and
2-52 become the male prongs of the distribution connector. Thus
upon installation of the removable portion 2-16 of the distribution
connector, these prongs are engaged by the female socket
connections housed in connector portion 2-16.
The insertion of the jumper in the fixed portion of the connector
is shown in detail in FIG. 3, wherein a portion of the insulative
base 3-2 is removed. Thus in the cut away portion of the drawing,
the jumper 3-50 is shown inserted in the fixed portion 3-14 of the
distribution connector.
FIG. 4 illustrates a detailed portrayal of a preferred jumper. It
goes without saying that this jumper can have numerous
configurations and is therefore not limited to one input finger and
five output fingers shown in the figure. Similarly many
configurations of the fingers themselves are possible in the
existing connector art. Thus they may be round, for example, and
they may be held in the connector shell in numerous ways.
What has been shown and described is an electrical connector with a
first and a second portion in which a plurality of output terminals
are derived from one of the portions for each input wire entering
the same portion. This is accomplished through the use of an
inserted jumper means on the opposite portion of the connector
shell.
Obviously many modifications and variations of the present
invention are possible in the light of the above teachings. It is
therefore to be understood that within the scope of the appended
claims, the invention may be practiced other than as specifically
described and illustrated.
