1. Technical Field
The present disclosure is directed to electrical connector assemblies for use with electrical wires/cables that include at least one plug member, particularly preterminated wires/cables. The present disclosure is further directed to connector assemblies (e.g., port replication connector assemblies) and associated plugs and cables that are adapted for use in multi-connector panels and with patch panels, e.g., for distributing data to computers and computer networks.
2. Background Art
With the continued evolution of data communications equipment, performance standards and requirements continue to advance. The structured cabling industry has experienced a progression from Category 3 level performance standards/requirements, through Category 5/5E, Category 6, and, more recently, Category 6A performance standards/requirements. At each stage, manufacturers of cabling and connector technologies have been required to address data communication capabilities and limitations of their existing product offerings. Of importance in meeting industry requirements is the control/minimization of noise/cross-talk encountered in cabling and connector assemblies. In general, noise/cross-talk issues become more pronounced as data communication frequencies are increased.
Typical connector assemblies include a jack and a plug that are adapted to detachably engage to effect a data communication connection. Common RJ 45 connector assemblies include a jack and a plug, each of which includes eight conductors in a predefined side-by-side orientation. Various techniques have been developed to control/address noise and crosstalk that are generated in the jack/plug interface, including capacitive compensation in the jack and/or plug. Noise/crosstalk compensation may be introduced through physical arrangements of the conductors within the jack and/or plug, as well as compensation introduced on printed circuit boards associated with the jack and/or plug.
Alternative conductor layouts for purposes of jack/plug combinations have been proposed. For example, U.S. Pat. No. 6,162,077 to Laes et al. and U.S. Pat. No. 6,193,533 to De Win et al. disclose male/female connector designs wherein shielded wire pairs are arranged with a plurality of side-by-side contacts and additional contact pairs positioned at respective corners of the male/female connector housings. The foregoing arrangement of contacts/contact pairs for shielded cables is embodied in an International Standard—IEC 60603-7-7—the contents of which are incorporated in their entirety herein by reference. The noted IEC standard applies to high speed communication applications with 8 position, pairs in metal foil (PIMF) shielded, free and fixed connectors, for data transmissions with frequencies up to 600 MHz.
In completing cabling installations, it is generally necessary to feed wiring/cabling from location-to-location, e.g., through conduits and/or in open spaces behind walls, above ceilings and below floors. Frequently, the wire/cable is fed from spools, introduced through the back/side of a wiring box, and terminated by an installation professional, e.g., by punching down individual wires with respect to insulation displacement connectors (IDCs) or the like. According to this conventional installation technique, the installer is able to define the length of each wiring/cabling run at the time of installation, thereby maintaining flexibility. However, the termination process is time-consuming and it is necessary to test/confirm system performance after the installation is complete.
As an alternative installation technique, preterminated wires/cables may be employed to achieve point-to-point wiring connectivity. A preterminated wire/cable generally includes a plug that is pre-mounted with respect to at least one end of a predetermined length of wire/cable. The plug is generally mounted with respect to the wire/cable by the manufacturer and, as part of the manufacturer's quality control procedures, performance at the interface between the wire/cable and the pre-mounted plug is verified before shipment to the installation site.
One type of cabling task is the connection of server(s)/switch(es) to a computer or network of computers. This is sometimes accomplished through the use of rack-mounted patch panels. Patch panels allow establishing and re-routing connections, i.e., by re-arranging the connections, e.g., by removing plugs from jacks and inserting them in alternative jacks. While this type of connectivity provides flexible connections, the plug/jack connections are subject to wear and distortion leading to defective connections and requiring replacement of the jack, cable and/or plug. In instances where the jack is attached to an expensive piece of electronic equipment, such as a server or switch, replacement of a jack can be both inconvenient and expensive and/or places expensive equipment at risk due to the necessity to move and disassemble the equipment.
Despite efforts to date, a need remains for connector assemblies and associated plugs/cables and related methods of use that provide enhanced flexibility and/or performance. These and other needs are satisfied by the connector assemblies, plugs/cables, techniques and methods disclosed herein.

Additional advantageous features, functions and benefits of the disclosed connectors, cable/plug assemblies and techniques will be apparent from the detailed description which follows, particularly when read in conjunction with the appended figures.
To assist those of skill in the art in making and using the disclosed connectors and plug/cable assemblies, reference is made to the accompanying figures, wherein:
In general, improved connectors and cable/plug assemblies are provided for use in distributing data. In exemplary embodiments, the present disclosure provides for advantageous electrical connector assemblies for use with electrical wires/cables (e.g., preterminated wires/cables) that include at least one plug member. More particularly, the present disclosure provides for improved connector assemblies (e.g., port replication connector assemblies) and associated plugs/cables that are adapted for use in multi-connector panels and with patch panels, e.g., for distributing data to computers and computer networks.
Current practice provides that one type of cabling task is the connection of servers or switches to a computer or network of computers, which is sometimes accomplished through the use of rack-mounted patch panels. In general, patch panels allow establishing and re-routing connections by removing plugs from jacks and inserting them in alternative jacks. However, while this type of connectivity provides flexibility, the plug/jack connections are subject to wear and distortion leading to defective connections and requiring replacement of the jack, cable and/or plug. For example, where the jack is attached to an expensive or complex piece of electronic equipment (e.g., server or switch), replacement of a jack can be both inconvenient and expensive. Such replacement may also place expensive equipment at risk due to the necessity to move and disassemble the equipment. In exemplary embodiments, the present disclosure provides for improved port replication connectors and cable/plug assemblies for use between servers/switches and the like and patch panels or connectors or the like to eliminate or reduce the need to remove the jack/plug connection at the server/switch while also providing flexible re-routing connections throughout the data system, thereby providing a significant manufacturing and commercial advantage as a result.
In the description which follows, like parts are marked throughout the specification and drawings with the same reference numerals, respectively. Drawing figures are not necessarily to scale and in certain views, parts may have been exaggerated for purposes of clarity.
Referring now to the drawings,
As shown in
Stated another way, when the jack fields 126 of server/switch 120 are used regularly for cross connect administration, the ports and/or jacks 126 of server/switch 120 may become damaged. To mitigate this risk to costly active equipment (e.g., server/switch 120), port replication panel assembly 148 may be advantageously introduced between patch panel 136 and server/switch 120, via cable 156 and plugs 158, 160. This thereby creates a replicated port, providing an efficient and low cost administration point, while leaving the server/switch 120 port(s) essentially untouched.
As noted above and as shown in
Cable assembly 155 is typically a preterminated assembly, whereby plugs 158, 160 are pre-mounted to cable 156 before shipment to an installation location or distribution channel. In general, individual wires of plugs 158, 160 are brought into electrical communication with electrical contacts 157, 159 that are exposed relative to the exterior of plugs 158, 160. In exemplary embodiments, contacts 159 of plug 160 are positioned in quadrants of plug 160 such that plug 160 complies with the contact geometry set forth in the IEC 60603-7-7 standard. Plug 160 with IEC 60603-7-7 contact geometry is advantageously adapted to engage and electrically communicate with a jack assembly (e.g., jack 154 of port replication panel assembly 148). In general, contacts 157 of plug 158 are positioned in a conventional 8-position RJ 45 contact layout, although the present disclosure is not limited thereto.
Such configuration of cable assembly 155 results in exemplary plug 160 being reduced in size, thereby enabling easier routing of cable assembly 155 through the system (e.g., through the racks, cabinets, cable management systems and/or pathways) while providing a high speed connection. In addition, individual plugs 160 of bundled cable assemblies 155 can be passed through one at a time through the system or data center. When in position, exemplary plugs 160 are configured and dimensioned to snap fit, attach and/or terminate into the rear of assembly 148, completing the termination. In exemplary embodiments, cable assembly 155 allows for improved pair-to-pair isolation and improved pair balance through cable assembly 155, which results in greater channel immunity from internal and or external noise, which ensures consistently high performance links and channels. More particularly, cable assembly 155 improves crosstalk and balance performance by isolating pairs and maintaining pair geometry through the termination.
Moreover, it has been found that each use of an IEC 60603-7-7 jack/plug combination (e.g., in the system illustrated in
