Description

BACKGROUND

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.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

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, FIGS. 1 and 2 show a connector assembly 10 having a first housing 12 and second housing 14 that are adapted to latch together, e.g., by latching members 18, 20 extending from the top surface of first housing 12 and latching member 24 (FIG. 2) extending from a bottom surface of housing 12. Such latching members 18, 20, 24 detachably engage mating slots formed in second housing 14. Second housing 14 has a jack opening 26 on a face 28 thereof. A label slot 30 is provided above jack opening 26 on face 28 to permit an installer to label the electrical connection associated with jack opening 26 for future reference. A jack opening 32 (FIG. 2) is formed on face 34 of first housing 12. A set of contacts 36, 38, respectively, are presented at jack openings 26, 32. In the embodiment shown in FIGS. 1 and 2, the contacts 36, 38 are configured to define two different types of standard jacks, namely, an IEC 60603-7-7 jack at jack opening 26 and an RJ 45 jack at jack opening 32. First housing 12 and second housing 14 are typically fabricated from a plastic material, e.g., polycarbonate.

FIG. 3 illustrates a connector assembly 40 having a pair of housings 42, 44 like those of the embodiment shown in FIGS. 1 and 2. The housings 42, 44 capture a contact subassembly 46 therein when snapped/attached together. Contact subassembly 46 has printed circuit board 48 which electrically connects a first set of electrical contacts 50 to a second set 52 (shown in dotted lines). In the embodiment shown in FIG. 3, the first set of electrical contacts 50 have a configuration suitable for an IEC 60603-7-7 jack and the second set of electrical contacts 52 are in the form of an RJ 45 jack. As described more fully in the applications incorporated herein by reference above (e.g., the parent patent applications), a plurality of contact support members 54, 56, 58, 60 provide mechanical support for the first set of contacts 50 and the printed circuit board 48 provides electrical connectivity between the contact sets 50 and 52, e.g., through circuit traces and/or cross-talk compensation circuitry.

FIG. 4 shows an alternative connector 70 similar to those described above relative to FIGS. 1-3, but having first and second jacks 72, 74 of the same type, illustrating that the present disclosure is intended to encompass a connector 70 having two jacks of the same type. While jacks 72, 74 have features indicative of an IEC 60603-7-7 jack, i.e., the contacts 76 are longitudinally opposed, the jacks 72, 74 could be in any form, e.g., both could be RJ 45 jacks or they could be two different types of jacks. FIG. 5 diagrammatically shows the contact configuration 90 for an IEC 60603-7-7 jack and FIG. 6 diagrammatically shows the contact configuration 92 for an RJ 45 jack. Referring again to FIG. 4, variations in the housing 78 may be made, e.g., by providing a housing bifurcated at the plane of the cross-section, as illustrated in FIG. 4, and capturing a printed circuit board 80 (that intermediates between the jacks 72, 74) in an internal groove 82, when conjoined to form the housing 78.

FIG. 7 shows a multi-connector panel assembly 100 having a first housing 102 with a plurality of jack openings 104, each for receipt of a mating plug (not shown). A second housing 106 has a corresponding plurality of jack openings 108. A contact subassembly 110 includes a PCB board 112 upon which is mounted a plurality of contact inserts 114 and a plurality of contact supports 116, which are grouped in sets like those shown in FIG. 3 to configure a plurality of contacts in a standard configuration, such as those of IEC 60603-7-7 jacks. The contact inserts 114 house a plurality of contacts like contacts 52 of FIG. 3 and insert into jack openings 108. The contact supports 116 provide mechanical support for a plurality of contacts (e.g., similar to contacts 50 of FIG. 3), and the contact supports 116 are slideably received in first housing 102 providing jack openings 104 with the contacts required of a standard jack, e.g., an IEC 60603-7-7 jack. FIG. 7 therefore illustrates that the connector technology described above in reference to FIGS. 1-6 can be replicated in multiple, side-by-side units to yield a multi-connector panel 100. As noted above with respect to the individual connectors of FIGS. 1-6, the connector configuration available at jack openings 104 and 108 can be the same or may be different, e.g., one or both may be RJ 45 or IEC 60603-7-7 jacks, and the jacks at jack openings 104 are in electrical communication with corresponding jacks present at jack openings 108 (e.g., via PCB board 112).

FIGS. 8 and 10 show diagrams of the connection of a server or switch 120 to a computer 121 or a computer network (not shown) via intermediating elements ending in a cable 122 and plug 124 that may be connected to jack 125 on the computer 121 or computer network. The server 120 has a plurality of outlet jacks 126, e.g., RJ 45 jacks that may receive a mating plug, such as plug 128 on cable 130. Cable 130 has another plug 132 at the other end, which is plugged into a mating jack 134 of a first patch panel 136. The jack 134 is connected at the rear of patch panel 136 to an intermediate cable 138, typically by a punch-down IDC (insulation displacement connector) 137 (See FIG. 10). The intermediate cable 138 runs to and connects to the rear of a jack 140 of a second patch panel 142, again typically by a punch-down IDC connector 139. The jack 140 to which cable 138 connects may receive a plug 144 of cable 122, the other end of which 124 plugs into jack 125 of computer 121. Typically all plugs 124, 128, 132 and 144 in this arrangement are RJ 45 plugs. As shown in FIG. 10, in the event that it is desirable to re-rout cable 122 to another jack 140a, i.e., to occupy the position shown in dotted lines and labeled 122a, it would be necessary to either break the connection 139 and move cable 138 to connection 139a, or to put a new cable 146 to connection 137a associated with jack 134a. This would further require unplugging plug 132 from jack 134 and moving it to position 132a in socket 134a. It is possible to do this without harm, but each instance of unplugging/plugging a plug into a jack risks bending, breaking or otherwise disturbing the contacts of the plug/jack. While the breakage of a jack 134 or a plug 132 is relatively inconsequential in itself, if the plug 132 is broken, then the cable 130 would need to be replaced, necessitating removal of plug 128 from jack 126 which is located on the server/switch 120. As noted before, each instance of unplugging/plugging into the jack 126 increases the risk that the jack 126 will be compromised. In the event that jack 126 is compromised, it would be necessary to remove and replace the jack 126 in the server/switch 120, thereby necessitating the removal, disassembly, re-assembly and/or replacement of the server/switch 120, thereby placing the expensive server/switch 120 at risk of damage.

FIGS. 9 and 11 show an embodiment in accordance with the present disclosure wherein an advantageous port replication panel assembly 148, like multi-connector panel assembly 100 shown in FIG. 7 (or like connector assemblies shown in FIGS. 1-4), is used to intermediate between the server/switch 120 and the patch panel 136. In one embodiment, port replication panel assembly 148 has more connectors or grouped contacts 150, each with front and rear jacks 152, 154, respectively, than are shown in the multi-connector panel assembly 100 of FIG. 7, but is otherwise constructed with similar features and functionality. A cable assembly 155 (FIG. 12) with a connector cable 156 has a plug 158 at one end with the appropriate configuration for reception by the jack 126 (e.g., RJ 45 jack) of the server/switch 120, which is unchanged from the example shown in FIGS. 8 and 10, and a plug 160 at the other end for reception in jack 154 (e.g., IEC 60603-7-7 jack) of the port replication panel assembly 148. (FIGS. 9 and 11). Typically, jack 126 of server/switch 120 is an RJ 45 jack, although the present disclosure is not limited thereto.

FIG. 12 shows exemplary cable assembly 155 including cable 156 having a male plug 158, 160, respectively, at each end. As shown in FIG. 11, cable assembly 155 is advantageously configured and dimensioned to connect server/switch 120 to the port replication panel assembly 148. In the embodiment shown, plug 158 typically has an RJ 45 configuration, and plug 160 typically has an IEC 60603-7-7 configuration. Thus, rear jack 154 utilized in exemplary port replication panel assembly 148 is an IEC 60603-7-7 jack that is configured and dimensioned to matingly receive plug 160 of cable assembly 155. Front jack 152 of port replication panel assembly 148 could be either an IEC 60603-7-7 jack or another type of jack, e.g., an RJ 45 jack. Cable 156 typically features shielded twisted pair (STP), fully shielded twisted pair (FTP) or unshielded twisted pair (UTP) wires.

As shown in FIG. 11, in the event that it is desirable to re-rout cable 122 to another jack 140a, i.e., to occupy the position shown in dotted lines and labeled 122a, it would be necessary to either break the connection 139 and move cable 138 to connection 139a, or to put a new cable 146 to connection 137a associated with jack 134a. This would further require unplugging plug 132 from jack 134 and moving it to position 132a in jack 134a. As noted above, each instance of unplugging/plugging a plug into a jack risks bending, breaking or otherwise disturbing the contacts of the plug/jack. However and in distinct contrast to the prior art system described above in FIGS. 8 and 10, if plug 132 in the disclosed advantageous system of FIG. 11 is broken and cable 130 needs to be replaced, this would only necessitate the removal of plug 128 from front jack 152 of port replication panel assembly 148, and not from jack 126 of the expensive server/switch 120 as is the case with the prior art system illustrated in FIGS. 8 and 10. The improved system disclosed in FIGS. 9 and 11 thereby reduces the risk that jack 126 of expensive server/switch 120 is damaged/compromised, thereby providing a significant manufacturing and commercial advantage as a result. In the event that port replication panel assembly 148 becomes damaged over time, the general replacement cost and network downtime would be significantly less than the expense of replacing/repairing server/switch 120.

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 FIG. 12, plug 158 typically has an RJ 45 contact layout configuration, and plug 160 typically has an IEC 60603-7-7 contact layout configuration. In exemplary embodiments, cable assembly 155 utilizes a modular plug termination (RJ 45) at plug 158 and a cable termination (IEC 60603-7-7 standard) at plug 160.

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 FIG. 11) reduces cross-talk over other types of jack/plug combinations, such as an RJ 45 jack/plug combination. Thus, it may be beneficial to utilize port replication panels 148 to replace the patch panels, e.g., patch panels 136 and 142 shown in FIG. 11, in each instance using an IEC 60603-7-7 jack/plug combination at each interface where it can be used (e.g., at 132/134, 137, 139 and/or 140/144). With such configuration, cable 122 could be replaced with a cable similar to cable 156, i.e., with the computer/computer network 121 typically utilizing an RJ 45 jack for receiving an RJ 45 plug.
