[0003] Growing demand for data transfer reliability, speed, and capacity has emphasized the capabilities of a distributed network. As more users of a distributed network utilize signal carrying components to transfer data, network delays and errors may occur more frequently, which prompts consistent expansion and improvement of assorted aspects of the distributed network to provide sufficient bandwidth and reliability. Such network expansion and improvement may include the installation of wired cables that provide robust environmental resistance and reliable signal carrying performance.
[0004] With more cables being utilized in distributed networks, cables of different sizes, types, and capabilities have been developed to accommodate diverse installation environments, such as residential, commercial, and industrial sites, as well as diverse connectivity and signal carrying capabilities. However, the diversity of cables and cable connections that may be employed to form a distributed network may present installation efficiency and accuracy issues along with potential for degraded operation over time as cables, and cable connections, incur movement and environmental conditions.
[0005] For example, to make a jack or plug connection, it is often needed to basically splice cables together. For single pair ethernet cables, for example, data signals and power must be transferred to a printed circuit board that will serve a mating to another printed circuit board.
[0006] Thus, it may be desirable to provide the assorted embodiments of the present disclosure, which are generally directed to provide a secure connection between a cable and a printed circuit board in field terminated applications.SUMMARY

[0052] Embodiments provide connectivity for a single pair ethernet cable by employing a connector structured and adapted to connect to the single pair Ethernet cable. The use of a printed circuit board to as a portion of the connector may providereliable, and repeatable, physical engagement for cable connections that promote stable signal carrying pathways in a relatively small form factor.
[0053] Reference will now be made in detail to presently preferred embodiments and methods of the present disclosure, which constitute the best modes of practicing the present disclosure presently known to the inventors. However, it is to be understood that the disclosed embodiments are merely exemplary of the present disclosure that may be embodied in various and alternative forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for any aspect of the present disclosure and / or as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
[0054] It is also to be understood that this present disclosure is not limited to the specific embodiments and methods described below, as specific components and / or conditions may, of course, vary. Furthermore, the terminology used herein is used only for the purpose of describing particular embodiments of the present disclosure and is not intended to be limiting in any way.
[0055] The proliferation of wired cables and connections has allowed distributed networks to provide reliable signal transmission to greater numbers of users. The availability of different signal carrying cables, and cable terminations, allows for customized physical arrangements and signal carrying capabilities. However, such diversity in cable configurations may present a variety of different termination, and connection, options that have different installation efficiencies and / or reliability risks over time. Accordingly, various embodiments are directed to a wired cable termination that employs a printed circuit board to provide increased installation efficiency and robust reliability over time.
[0056] The assorted embodiments of a connector may be practiced in a distributed network. FIG. 1 is a block representation of a distributed network environment 100 that may employ one or more connectors to form signal pathways 110 between one or more sources 120 and one or more destinations 130. The distributed network 100 may employ any number, and type, of signal pathway 110 to supply one-way or two-way signal transmission.
[0057] In some embodiments, a wireless signal pathway 112 is utilized to transmit data while other embodiments employ a wired signal pathway 114. It is noted that thewired signal pathway 114 is not limited to a particular type, size, or signal carrying speed. As such, the wired signal pathway 114 may transfer signals with fiber optic aspects or conductive wires packaged in an environmentally protected jacket. In contrast to the wireless signal pathway 112 that converts signals into a form that may be distributed without physical aspects of wired signal pathway 114, transmitting data via a wired cables may provide greater performance and / or capabilities, such as signal integrity, reliability, speed, and cost.
[0058] While wired signal pathways 114 may provide some operational advantages over wireless signal pathways 112, the presence of a physical cable to house, guide, and protect signal carrying aspects may present operational challenges. For instance, a wired cable may not be long enough, or physically compatible with, some installation sites, such as multi-residence complexes. Multiple wired cables may form a stable wired signal pathway 116 with the incorporation of an interconnect 140, such as a server, switch, cassette, or splitter. The use of an interconnect 140 may provide the ability to employ different wired cables to customize the physical delivery and electrical capabilities, provided to a destination 130. However, employing separate wired cables to form a signal pathway 114 introduces additional physical connections that may present installation and / or operational challenges.
[0059] FIG. 2 illustrates a cross-sectional line representation of a wired cable connection 200 that may be present in the distributed network 100 of FIG. 1 to establish a stable signal pathway 114. A first wired cable 210 is physically and electrically connected to a second wired cable 220 via a coupling interconnect 230. The respective wired cables 210 / 220 may have matching, or dissimilar, constructions and / or capabilities. In the non-limiting embodiment of FIG. 2, each wired cable 210 / 220 is structurally adapted as an ethernet cable that presents a single pair of signal conducting wires 240. Such cable construction may be characterized as a single pair ethernet (SPE) cable that may provide a relatively small physical form factor and sufficient signal carrying capabilities to service a diverse variety of destinations, such as sensors, devices, components, and computing systems.
[0060] The coupling interconnect 230, in some embodiments, has conducting portions 232 that provide a transition between wires 240 of the respective cables 210 / 220. However, the physical attachment of a cable 210 / 220 to the coupling interconnect 230 may present an electrical connection that has limited capabilities.Even with an ideal installation of the cables 210 / 220 on the coupling interconnect 230, environmental conditions, such as movement and vibrations over time, may degrade the physical and electrical connections from cable 210 to cable 220.
[0061] These installation and operational concerns for a cable connection may be addressed by various embodiments of a connector structured and adapted to connect to a cable, such as a single pair Ethernet cable. In some embodiments, a connector portion may be structured and adapted to connect to a cable at a first end and receive a printed circuit board at a second end. In certain embodiments, the printed circuit board may be a printed circuit board or lead frame. FIGS. 3A and 3B respectively illustrate perspective views of portions of a connector portion 300 that may be employed in the cable connection 200 of FIG. 2 and the distributed network 100 of FIG. 1 and other embodiments to provide enhanced installation and operational efficiency, accuracy, and reliability. To clarify, the perspective view of FIGS. 3A conveys a frontal side of the connector portion 300 while the perspective view of FIG.3B conveys a side or perspective view of the connector portion 300.
[0062] The connector portion 300 may be structured and adapted to connect to the cable (cable portion) 310, which in some embodiments may be a single pair Ethernet cable. The connector portion 300 may include a wire manager portion 320. The cable 310 may be any size, type, or construction of signal carrying component while the wire manager portion 320 of the connector portion 300 may be structured and adapted to connect to any number of signal carrying wires 322, 324 present in the cable 310. The wire manager portion 320 may be structurally adapted to physically engage with the signal carrying wires 322, 324. For instance, the cable 310 may be an SPE cable having a pair of signal carrying conductors or wires 322, 324 packaged within a jacket 316. In various embodiments, the jacket 316 may be insulating, reinforced, flexible, or rigid to allow for diverse installation capabilities.
[0063] While not required or limiting, in some embodiments, the wires 322, 324 of the cable 310 may be structured and adapted to partially, or completely, surround at least a portion of the wire manager portion 320. The wire manager portion 320 may be in line or parallel with the direction of the cable 310. The conductors or wires 322, 324 may make a turn to be substantially perpendicular relative to the wire manager portion 320 which in some embodiments may by a printed circuit board (PCB) or other printed circuit board. The perpendicular turn of the wires 322, 324 may be structurallyadapted to assist with cable strain relief. In certain embodiments, the wires 322, 324 may be turned or bent towards each other as seen in FIG. 3A, or alternatively the wires 322, 324 may be turned or bent away from each other. The wire manager portion 320 may, in some embodiments, provide structural support for the wires 322, 324. In some embodiments, the wire manager portion 320 may include attachment features, such as tabs, grooves, ridges, or indentations 326 defined in either lateral side of the end portion 320, that may aid the physical attachment, and retention, of each of the wires 322, 324 to the wire manager portion 320. The wire manager portion 318 may also include contact portions 328 defined in a distal end of the end portion 320, each contact portion 328 being structured and adapted to accommodate or hold a respective one of the wires 322, 324 of cable 310 therein. In certain embodiments and seen in FIG. 3A, the wires 322, 324 are seen as being disposed within an indentation 326 and extending around the contact portion 328 and are structurally adapted to substantially wrap or “hug” the end portion 320. In certain embodiments, the end portion 320 may include a collar portion 330 which is structurally adapted to connect or couple the wire manager portion 320 to the cable 310.
[0064] The wire manager portion 320 may be a rigid substrate and, in some embodiments, may be formed form a material, such as a glass, silicon, or resin, which provides physical strength conducive to repeated engagement, and removal, with one or more receiving portions. For instance, the wire manager portion 320 may be structurally adapted to physically mate with a matching end portion of a separate cable, with another connector or, in some embodiments, with a port of an electronic device or network interconnect. The construction of the wire manager portion 320, which in some embodiments may be a printed circuit board, allows for various lithography and other manufacturing techniques to create electrical leads that may be directed to any number, and type, of electrical contacts. With the ability to construct stable and precise electrical leads through, or atop of, the wire manager portion 320 may be arranged with multiple different electrical contacts for each signal carrying conductor or wires 322, 324. In certain embodiments, the contact portions 328 may include one or more contact pads disposed therein which are structurally adapted to make electrical contact with the wires 322, 324.
[0065] According to certain embodiments and as seen in FIGS.4A and 4B, the connector portion 400 may include wires 422, 424 of a cable 410 that may bestructured and adapted to make partial or complete contact with a printed circuit board 420 having a plurality of edge contacts or edge plating 426 disposed on a plurality of edges which form a lateral edge of the printed circuit board 420 itself. In certain embodiments, the printed circuit board 420 may be a PCB. The printed circuit board 420 may include a number of connection portions 428 defined in a lateral edge of the printed circuit board 420, wherein each of the connection portions 428 are plated or include edge contacts 426 that are structurally adapted to make an electrical connection with each of the conductors or wires 422, 424. The edge plating 426 may be disposed on each of the internal surfaces of the connection portions 428, for example, as seen in the magnified view of FIG. 4B, edge plating 426 may be disposed on an upper surface 430a of the connection portion 428, a lower surface 430b of the connection portion 428, and / or on an inner surface 430c of the connection portion 428. In certain embodiments, the conductor or wires 422, 424 make direct contact with the edge plating 426, for example with the edge plating 426 disposed on the inner surface 430c of the connection portion 428 as seen in FIG.4B. The conductors or wires 422, 424 may be forced against the edge plating 426 of the printed circuit board 420, while in certain embodiments the edge plating 426 of the printed circuit board 420 may be forced against the conductors or wires 422, 424. In certain embodiments, both the printed circuit board 420 and the conductors or wires 422, 424 are forced against each other.
[0066] According to certain embodiments and as shown by the views of FIGS. 5A-5C and 6A-6D, the connector portion 500, 600 may include means for guiding, supporting, applying, biasing, or compressing electrical conductors or wires 522, 622 from the cable 510, 610 to at least one contact pad disposed on the printed circuit board 520, 620. In certain embodiments, the means for guiding, biasing, or compressing include at least one intermediary element, the conductor or wire 522, 622 being structurally adapted to make contact with the intermediary element before the intermediary element itself makes contact with the printed circuit board 520, 620. According to certain embodiments, the intermediary element may include but is not limited to solder, springs, insulation-displacement contact (IDC) blades, piercing blades, or a combination thereof.
[0067] For example, in certain embodiments as seen in FIGS. 5A-5C, and although not required or limiting, each conductor or wire 522 of the connector portion500 may make contact with a biasing portion 530 disposed in the wire manager portion 512. Each biasing portion 530 may at least be partially disposed within each connection portion 528 when in use, namely after the printed circuit board 520 has been connected to the wire manager portion 512. In accordance with some embodiments, the respective biasing portions 530 are positioned in the wire manager portion 512 in order to make contact with the conductors or wires 522 and provide an efficient application of force onto the edge plating 526 of the printed circuit board 520 as the printed circuit board 520 and a base or wire manager portion 512 are brought together.
[0068] Hence, according to certain embodiments, the biasing portion 530 may provide enhanced connectivity between the cable 510 and the printed circuit board 520 which may include a consistent or reliable electrical connection between the edge plating 526 and the corresponding conductor or wire 522. For example, the connector 500 may be structured and adapted to provide a secured physical connection of the conductor portions or wires 522 between the printed circuit board 520 and the cable 510 which in turn ensures that an established electrical pathway between the cable 510 and the connector 500 is maintained while the connector 500 is in use, even during movement of the cable 510, the printed circuit board 520, and / or the connector 500. In certain embodiments, each connection portion 528 may be structured and adapted with a shape to mate with, and make electrical connection with, both the biasing portion 530 and the conductor or wire 522.
[0069] According to certain embodiments, the biasing portion may be a compressive biasing portion 532 as seen in FIG. 50. The compressive biasing portion 532 may include a first end 534 that is connected or embedded into the printed circuit board 520 and a second end 536 that is structured and adapted to provide a biasing force against the conductor portion 522 so as to maintain physical contact between it and the compressive biasing portion 532 and press the conductor portion 522 against the edge plating 526.
