RJ45 CONNECTOR
BACKGROUND
Field of the Invention The present invention relates to the field of connectors. More particularly, the present invention relates to the field of connectors used in communications infrastructure.
Description of the Related Art
Currently available RJ45 connectors are available in male or female connector types. To complete a connection, a male connector must be joined with a female connector.
Male to male and female to female connectors are, by design, not possible.
One way of connecting a cable terminating in a male connector to a similar cable also terminating in a male connector is to use a female bridge cable or in-line coupler. A female bridge or in-line coupler has a female connector on each end. The female connectors are connected to the male connectors, thereby providing an electrical connection between the two male connectors. While this method allows an electrical connection to be made between the two male connectors, it may require the use of additional lengths of cable, thereby adding to the cost of the installation. Additionally, in applications where space is at a premium, the addition of two female connectors and a length of cable may be undesirable.
Another method of interconnecting two cables terminating in male connectors is to remove one of the male connectors and replace it with a female connector. This is a potentially time consuming process, especially in installations when many male to male connections need to be made. The time associated with the replacement of male connectors with female connectors can add significantly to the cost of completing the installation and can also result in delays in the completion of the installation. Additionally, the greater the number of connectors the greater the number of points of failure.
These same problems occur when trying to connect two cables terminating in female connectors.
Accordingly, it is desired that the present invention overcome the limitations of currently available connectors.
SUMMARY OF THE INVENTION The present invention provides connectors for interconnecting standard male and standard female RJ45 connectors. In one embodiment, a in-line connector having two RJ45 male connector ends is used to couple a standard female RJ45 connector to another standard female RJ45 connector.
In an alternate embodiment of the present invention a hermaphroditic connector having a male RJ45 connector end and a female RJ45 punch-down body. The hermaphroditic connector coupling to a standard female RJ45 connector.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a pair of connectors for interconnecting standard male and standard female RJ45 connectors. In the following description, numerous details are set forth in order to enable a thorough understanding of the present invention. However, it will be understood by those of ordinary skill in the art that these specific details are not required in order to practice the invention. Further, well-known elements, devices, process steps and the like are not set forth in detail in order to avoid obscuring the present invention.
In the following figures like objects are given the same numbers in an effort to aid the reader in understanding the features of the present invention.
Figure 1 is a perspective view of a hermaphroditic connector (2) having a male RJ45 connector end (4) and a female RJ45 punch-down body (6). The male RJ45 connector end (4) is formed to allow interconnection with a standard RJ45 female connector (not shown). The male RJ45 connector end (4) is coupled to the female RJ45 punch-down body (6). Cable splines (30) protrude from the top of the female RJ45 punch- down body (6). The cable splines (30) connect to a cable (not shown) attached to the hermaphroditic connector (2).
Figure 2 is a side view of the male-to-female hermaphroditic connector (2) shown in Figure 1. Figure 3 is a bottom view of the hermaphroditic connector (2) shown in Figures 1 and 2. Figure 4 is an end view of the male end (4) of the hermaphroditic connector (2) shown in Figures 1-3.
Figure 5 is a side cross-sectional view of the hermaphroditic connector (2) shown in Figure 1-4. The contact blades (8) of the male connector end (4) are each individually connected to the paired cable spline (30). In this manner an electrical connection exists between the cable spline (30) of the standard female punch-down body (6) and the standard
male connector end (4). A cable installed on the standard female punch-down body is then in electrical contact with the contact blades of the male end.
Internally, each of the eight cable splines (30) of the female punch-down body (6) individually connect to the corresponding contact blade (8) of the male connector end (4). Each of the contact blades (8) is electrically insulated from all of the other contact blades and all of the cable splines (30), excepting the corresponding cable spline which it is electrically connected to.
As shown in Figure 2, the male connector end (4) of the hermaphroditic connector (2) is positioned along an axis (A- A) which runs through the female punch-down body (6). Alternatively, the male end (4) and female end (6) of the connector (2) can be positioned along either different parallel, or different non-parallel, axes.
As shown in Figure 4, the male end (4) is formed such that it fits into a standard female RJ45 punch-down body (not shown). The male end (4) is positioned relative to the female punch-down body (6) such the top face of the male end (4) points in the same direction as the top of the female punch-down body (6). In this manner the relative axial position of the male end and the female end are in alignment. Alternatively, the relative axial positions of the male end and female end can be formed in any position.
In an alternate embodiment of the present invention, the standard female punch- down body can be formed with the cable molded into the body. The female punch-down body (6) may include clasps, tabs or other retaining devices to keep the male end (4) from accidental separation with a standard female punch- down body.
Figure 6 is a perspective view of a in-line female-to-female RJ45 connector (20) having a first male RJ45 connector end (24) and a second male RJ45 connector end (26). Each male connector end (24) and (26) has a set of eight contact blades (28) for establishing electrical contact with the contact blades of a standard female RJ45 punch- down body (not shown) when the that male connector end is inserted into a standard female RJ45 punch-down body.
The interconnection body (25) positioned between the first male end (24) and the second male end (26) may include clasps, tabs or other retaining devices to keep the respective male end from accidental separation with a standard female punch-down body.
Figure 7 is side view of the in-line female to female connector (20) shown in Figure 6. The first male connector end (24) of the connector (20) is positioned along an axis (B-B) which runs through the second male connector end (26). Alternatively, the first and second male ends (24) and (26) of the connector (20) can be positioned along either different parallel, or different non-parallel, axes.
Figure 8 is a top view of the female-to-female connector (20) shown in Figures 6 and 7.
Figure 9 is an end view of the first male end (24) of the female-to-female connector (20) shown in Figures 6-8. The male end (24) is formed such that it fits into a standard female RJ45 punch-down body (not shown). The first male end (24) is positioned relative to the second male end (26) such the top face of the first male end (24) points in the same direction as the top face of the second male end (26). In this manner the relative axial position of the first male end and the second male end are in alignment. Alternatively, the relative axial positions of the first male end and the second male end can be formed in any position.
Figure 10 is a side cross-sectional view of the connector (20) shown in Figure 6-9. The contact blades (28) of the first male connector end (24) are each individually connected to the paired contact blade (28) of the second male connector end (26). In this manner an electrical connection between the contact splines of two female punch-down bodies (not shown) is established when the female-to-female connector (20) is installed.
While the above embodiments have been shown with eight contact blades per connector end, alternate embodiments could use more or fewer contact blades.
Although the invention has been described in conjunction with particular embodiments, it will be appreciated that various modifications and alterations may be made by those skilled in the art without departing from the spirit and scope of the invention.
