Description

[Technical field]

[0001] The present disclosure relates generally to network connectors, and more particularly to high speed network connectors with magnetics integrated into the connector. [Background technology]

[0002] In certain applications, Ethernet data travels over a transmission medium (e.g., an Ethernet UTP cable), through an Ethernet / network connector, and then through a media dependent interface (MDI) to a physical layer (PHY) or printed circuit board of a connecting device (e.g., a computer or server). A transformer is typically positioned between the transmission medium and the connecting device to condition (i.e., isolate) the electrical energy transmitted from the transmission medium to the connecting device. The transformer is typically separate from the network connector and therefore occupies valuable space on the printed circuit board. IEEE 802 is a set of local area network (LAN) technology standards that specify medium access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communications. The IEEE 802 standard establishes Data Terminal Equipment (DTE) Power over Media Dependent Interface (MDI), an international standard that defines power transmission over Ethernet infrastructure.

[0003] IX INDUSTRIAL connectors, a type of Ethernet connector, are high-speed network connectors featuring a small and robust design for use in industrial environments and on industrial equipment. IX INDUSTRIAL connectors are versatile and small I / O connectors for industrial machines. IX INDUSTRIAL connectors comply with IEC standards (IEC 61076-3-124), are compatible with high-speed data transmission, and have high EMC resistance. One such IX INDUSTRIAL connector is presented, for example, by Amphenol IC.

[0004] The Ethernet standard (set by IEEE) states that the physical layer must be galvanically isolated from the transmission medium. That is, the Ethernet standard requires that an electrical isolation transformer be positioned between the connecting device and the PHY chip that drives the signal to the connecting device. There are two basic reasons for this isolation requirement. The first is due to the possibility of ground offsets between devices located far away from each other. The second is to protect all devices from line disturbances such as shorts to high voltage rails, surge spikes, or electrostatic discharge (ESD) strikes. However, Ethernet connectors such as IX INDUSTRIAL connectors do not have a transformer as part of the connector to isolate the electronic signal, so a separate transformer is positioned between the connector and the transmission medium.

An internal printed circuit board may be supported on the core body. The internal printed circuit board may be coupled to the first set of contacts. An isolator may be mounted on the core body between the first and second sets of contacts. A shield at least partially surrounds the housing shell.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present disclosure relates to high speed network connectors including integrated magnetics. In one example of the present disclosure, the connector may be any network connector, such as a durable industrial connector, such as an IX INDUSTRIAL connector. The connector may be an A-code or B-code connector to meet the needs of a particular data or signal application. The connector may have a compact design that allows the connector to be used on smaller devices and / or to create multiple connection points in a limited space or area. The connector design may also be robust for secure connection to a mating connector, such as via metal locking tabs that are less likely to break if bumped or pulled. In one example, the connector also has shielding capabilities to block interference from nearby connectors or equipment, etc.

[0016] The connector of the present disclosure employs transformer isolation via integrated magnetics. In one example, certain magnetic components that are typically located on the PCB are instead integrated into the design of the connector itself. The integrated magnetics may provide electrical isolation between two circuits by transferring energy in magnetic form from one circuit to another and by physically and electrically isolating the two circuits. That is, the integrated magnetics may insulate the electronic circuits to protect them from electrical shock from the mains while simultaneously transferring electrical energy from one circuit to the other via magnetic coupling. As contemplated by the present disclosure, transformer isolation via integrated magnetics, when used in Ethernet applications, offers several advantages, such as: (a) there is no need for a voltage supply on the isolated side since the signals are transferred directly through the transformer; (b) transformers can accommodate Fast Ethernet signals (even at 10 Mbps) and are cheaper and more readily available than other isolation methods such as the use of optoisolators; (c) transformers, by their very nature, have a very high common mode rejection ratio (CMRR) and are therefore ideal for differential communication; (d) a voltage applied to both terminals of the transformer is sufficient to provide a stable signal; and (e) the voltage applied to both terminals of the transformer is sufficient to provide a stable signal; This may have several advantages, including: (a) all common mode voltages are rejected and only the differential voltage between the terminals is transmitted to the isolated side; (b) the impedance mismatch between the cable pair and the MDI pair is overcome, thereby allowing the signal to be transmitted without any reflections due to the matched impedance; and (c) high isolation voltage protection (standard requires withstand 1500VAC at 50 / 60Hz for 60 seconds between pairs or from one pair to chassis ground) is provided, thereby protecting the PHY or printed circuit board (PCB) side from the effects of ESD strikes.

[0017] Integrating magnetics into the connector may also have several other advantages, including reducing the manufacturing cost of the connector and / or associated PCB due to fewer BOM items, simplifying the assembly of the connector and associated PCB in the sense that the connector can be used immediately without the need for separate magnetics on the associated PCB, and simplifying the layout and design of the connector and PCB, reducing the risk of manufacturing errors. For example, for mass-produced commercial network systems, using connectors with integrated magnetics may reduce manufacturing costs and simplify the design process.

[0018] Referring to the drawings, Figures 1-8 show an example of a network connector 100 having a subassembly 101 including a core body 102, a plurality of contacts 104a, 104b, an internal printed circuit board 106, and a magnetic isolation component 110. A plurality of wires 116a (Figure 6) are coupled to the contacts 104a, 104b to provide a signal path (Figure 9) through the connector 100. The wires 116a are wrapped around the magnetic isolation component 110 to create a signal filter for the signal path, for example, to protect associated devices from line disturbances such as shorts to high voltage rails, surge spikes, or electrostatic discharge ESD strikes. Although the connector 100 is shown as a right-angle connector, the connector 100 may be a vertical connector or other connector orientations.

[0019] The core body 102 has a front end 120, a rear end 122, and a longitudinal intermediate portion 124 extending between the front end 120 and the rear end 122. The longitudinal intermediate portion 124 has a planar dividing panel 125 having a planar top 128, a planar bottom 130, and opposing sides 126a and 126b (also referred to as "side support surfaces"). The top 128 and bottom 130 extend in planes that are substantially parallel to one another, and the dividing panel extends between the top 128 and bottom 130 in a plane that is substantially perpendicular to the planes of the top and bottom 128, 130. The sides 126a, 126b are configured to support the magnetic isolation component 110. The opposing sides 126a and 126b can be substantially identical in one example. In other examples, the opposing sides 126a and 126b can be different. As seen in Figures 5, 7B and 7C, one or both side support surfaces 126a and 126b may be recessed to form respective cavities 144a, 144b.

[0020] The plurality of contacts 104a, 104b are supported by the core body 102. In one example, the plurality of contacts 104a, 104b are mounted on the core body 102 and coupled thereto, such as by an interference fit. The plurality of contacts 104a, 104b may include a first set of contacts 104a for coupling to the inner printed circuit board 106 and a second set of contacts 104b for coupling to the main outer printed circuit board 10 (FIGS. 1A and 10). Each of the contacts in the first set of contacts 104a has an exposed portion 132 (also referred to as a "post") that extends outside the core body 102, such as to the top 128 of the core body 102. Each of the contacts in the second set of contacts 104b has an exposed portion 134 (also referred to as a "post") that extends outside the core body 102, such as to the bottom 130 of the middle portion 124 of the core body 102.

[0021] 2 and 5, the internal printed circuit board 106 is supported on the core body 102, for example, at the top 128 of the core body 102, and is coupled to exposed portions or posts 132 of the first set of contacts 104a. In other examples, the internal printed circuit board 106 may be positioned elsewhere relative to the core body 102. For example, the printed circuit board 106 may be located on the bottom 130.

[0022] The magnetic isolation component 110 is supported on the core body 102, for example on one or both of the side support surfaces 126a and 126b within their respective cavities 144a, 144b, as seen in Figures 7B and 7C. As described above, the subassembly 101 of the connector 100 includes the contacts 104a, 104b mounted on the middle portion 124 of the core body 102, the magnetic isolation component 110 mounted on the side support surfaces 126a and 126b (only the side support surface 126a is shown) of the core body 102, and the internal printed circuit board 106 mounted on the upper portion 128 of the core body 102, as seen in Figure 5. The housing shell 150 of the connector 100 receives the subassembly 101.

[0023] In one example, the core body 102 is generally rectangular in shape and formed of any dielectric material. In other examples, the core body 102 may be other shapes, such as square and cube. The middle portion 124 of the core body 102 may be elongated (e.g., compared to the length of a conventional IX INDUSTRIAL connector) such that the length L of the middle portion 124 is at least twice the width W of the front and back ends 120 and 122 of the core body 102, as seen in FIG. 7A. In other examples, the length L may be more or less than twice the width W.

[0024] 7A-7D, the top 128 and bottom 130 of the intermediate portion 124 of the core body 102 each include a number of respective through holes 142a, 142b, each of which receives, such as with an interference fit, one of the first and second sets of contacts 104a, 104b. Each contact 104a, 104b extends through a respective through hole 142a, 142b such that exposed portions or posts 132 of the first set of contacts 104a are exposed at the top 128 of the core body 102 for coupling to the internal printed circuit board 106 (FIG. 2) and exposed portions or posts 134 of the second set of contacts 104b are exposed at the bottom 130 of the core body 102 for coupling to the main external printed circuit board 10 (FIG. 1A). The first and second sets of contacts 104a, 104b extend in a direction generally perpendicular to the longitudinal axis l of the core body 102, as seen in Figures 7B and 7C.

[0025] The cavities 144a, 144b formed in each of the side support surfaces 126a and 126b of the core body 102 are sized to receive the magnetic isolation component 110. In one example, each of the support surfaces 126a and 126b may be substantially flat for mounting the magnetic isolation component 110 thereon. Although two cavities 144a, 144b are shown, the core body 102 may have more or less than two cavities 144a, 144b. For example, in some examples, the core body 102 has a single cavity that holds the magnetic isolation component 110. In other examples, the two cavities 144a, 144b are further divided by one or more walls (e.g., the walls may be integral with the core body 102 and / or may be made of the same dielectric material as the core body 102), such that each pair of magnetic cores is separated by a wall from an adjacent pair of magnetic cores. Slots 148a, 148b (FIGS. 5 and 7A) may be provided in the top 128 and bottom 130 of the longitudinal intermediate portion 124 of the core body 102 above and below the cavities 144a, 144b, respectively. The slots 148a, 148b are sized and positioned to receive one of the ends 117 or 119, respectively, of the wire 116a, as seen in FIG.

[0026] In one aspect, the magnetic isolation component 110 can be multiple magnetic cores (e.g., cores of ferromagnetic material), such as cores 112, 114, around which the wire 116a can be wound. The wire 116a wound around the cores 112, 114 is coupled (e.g., both electrically and mechanically) to the first and second sets of contacts 104a, 104b, respectively, at ends 117 and 119 of the wire 116a. In one example, the cores 112, 114 are paired together, as seen in FIG. 4. In some examples, the wire is first wrapped around the core 112 and then around the core 114, or vice versa. The core 112 (T1) can be an isolation transformer that allows high speed signals to pass but rejects DC signals. The core 114 (T2) can be a common mode choke, which is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing desired DC or low frequency signals to pass. Thus, when paired together, the cores 112, 114 complement each other to filter signals passing through the wires extending between the contacts 104a, 104b of one pair. Thus, the wires may extend from the contacts 104a, wrap around the core 112, wrap around the core 114, and then couple with the contacts 104b. Referring to FIG. 7B, in one example, the magnetic isolation component 110 may include at least a first and a second pair of cores 112, 114. The first pair of cores 112, 114 includes a first isolation transformer (T1) and a first common mode choke (T2) paired together, and the second pair of cores 112, 114 includes a second isolation transformer (T1) and a second common mode choke (T2) paired together. Referring to FIG. 7C, the magnetic isolation component 110 may also include third and fourth pairs of cores 112, 114 comprising a first isolation transformer (T1) and a first common mode choke (T2) paired together, and a second isolation transformer (T1) and a second common mode choke (T2) paired together.

[0027] In some embodiments of the present disclosure, two pairs of cores 112 and 114 paired together are mounted in cavities 144a in one side support surface 126a of the dividing panel 125 of the middle portion 124 of the core body 102, as seen in FIG. 7B, and two other pairs of cores 112 and 114 paired together are mounted in cavities 144b in the other side support surface 126b of the dividing panel 125 of the middle portion 124 of the core body 102, as seen in FIG. 7C. The cores 112 and 114 can be mounted in each cavity 144 in a vertical orientation and aligned with the dividing panel 125. In other examples, the cores 112 and 114 can be mounted in each cavity 144 in an orientation other than a vertical orientation, as long as the cores 112 and 114 fit within the dimensions of the cavity 144. The cores 112 and 114 can be mounted in each cavity 144 via epoxy or resin, for example, the cores 112 and 114 can be attached to the sides 126a, 126b. In another example, the cores 112 and 114 can be mounted on one or both of the side support surfaces 126a and 126b of the core body 102 and encapsulated in resin, for example, which can protect the magnetic isolation component 110 from moving around during the life of the connector and also help provide dielectric isolation. In another example, only one pair of cores 112 and 114 can be provided on one or both of the side support surfaces 126a and 126b.

[0028] Each core 112 may have an increased outer diameter OD and a reduced thickness T (compared to a conventional magnetic core) such that the cores 112 fit within the dimensions of the cavity 144 of the core body 102, as seen in Figures 3A and 3B. In one example, the increased outer diameter OD of each core 112 (i.e., increased from the outer diameter of a standard magnetic core of 3.68 mm) may be in the range of 3.70 mm to 5.00 mm, or in another example, the range may be 4.00 mm to 4.85 mm, or in yet another example, the range may be 4.40 mm to 4.80 mm, such as about 4.60 mm. In one example, the reduced thickness T of each core 112 (i.e., reduced from a standard magnetic core thickness of 2.68 mm) may be in the range of 1 mm to 2.66 mm, or in another example, the range may be 1.25 mm to 2.50 mm, or in yet another example, the range may be 1.55 mm to 1.95 mm, such as about 1.75 mm. The foregoing include example dimensions and the increased outer diameter OD and thickness T may be other sizes in other examples.

[0029] As best shown in FIG. 2, the connector 100 may further include a shield 108. The shield 108 may be configured to surround or at least partially surround the subassembly 101 to protect the subassembly 101 from electromagnetic interference. The connector 100 may also include a housing shell 150 that receives the subassembly 101 and is covered or at least partially covered by the shield 108. The housing shell 150 may include a top 151, opposing sides 155, an interior receiving area 152 sized to receive the subassembly 101, a front end having an opening, an open rear end 153, and an open bottom 154. The open rear end 153 allows the subassembly 101 to be inserted into the interior receiving area 152 of the housing shell 150 when the connector 100 is assembled. The open bottom 154 allows the exposed portions 134 of the second set of contacts 104b to extend through the open bottom 154 for coupling to the external printed circuit board 10. Optionally, a bottom cover 156 can be provided on the open bottom 154 of the housing shell 150, and optionally, a rear cover can be provided on the open rear end 153. In one example, the bottom cover 156 and the rear cover can be made of any dielectric material. The exposed portions 134 of the second set of contacts 104b can also extend through the bottom cover 156, as seen in FIG. 1B.

[0030] In one example, the shield 108 can be made of a conductive material and can be configured to substantially surround the housing shell 150 and subassembly 101 of the core body 102, the contacts 104 (except for exposed portions or posts 134 configured for attachment to an external PCB), the internal printed circuit board 106, and the magnetic isolation component 110 to provide a generally 360 degree EMI shield for the connector 100 when the connector 100 is mounted on the external printed circuit board 10. In another example, the shield 108 can only partially surround the housing shell 150 and the subassembly 101 to provide a partial EMI shield. The shield 108 can include a top wall 170 and opposing longitudinal side walls 172 extending between a front end 174 (having an opening) and a rear wall 176 of the shield 108. The top wall 170 of the shield 108 can be sized to generally cover the top 151 of the housing shell 150, and the side wall 172 can be sized to generally cover the side 153 of the housing shell 150. The rear wall 176 of the shield 108 can be closed over the open rear end 153 of the housing shell 150 when the shield 108 is assembled onto the housing shell 150. In one example, the shield 108 can be formed of any conductive material. In other examples, a portion of the shield 108 can be open and / or formed of a dielectric material. For example, one or more of the top wall 170 or the side wall 172 of the shield 108 can be removed, have a notch, and / or be formed of a dielectric material or a semiconductive material instead of a conductive material. The shield 108 also includes one or more tails 178 at the bottom of the shield 108 for insertion into an external printed circuit board 10 for electrical and mechanical connection to the external printed circuit board 10. The tail 178 is connected to a ground circuit through the printed circuit board 10 .

[0031] Both the housing shell 150 and the shield 108 can have a generally rectangular shape. In other examples, the housing shell 150 and the shield 108 can have other shapes, such as square and cubic. Optionally, one or more EMI fingers 179 can be provided on the top wall 170 and / or side wall 172 of the shield 108 for ground connection to a mating connector and / or to an adjacent connector 100 to form a common ground.

[0032] 2 and 5, the connector 100 further includes a mating interface part 160 having a plurality of mating contacts 162 for coupling to the internal printed circuit board 106. The mating interface part 160 is designed to connect with a mating connector, such as a cable plug (at the mating connector side 12, as seen in FIG. 9), thereby electrically connecting the mating connector to the main printed circuit board 10 through the connector 100. The mating interface part 160 has an interface 163 that supports the mating contacts 162 for connecting with corresponding contacts of the mating connector. The mating interface part 160 is coupled to the front end 120 of the core body 102 in a position to mate with the mating connector. The front end 120 of the core body 102 includes an engagement feature 146 for engaging with a corresponding engagement feature 164 of the mating interface part 160, as seen in FIGS. 2 and 5. In one example, the engagement feature 146 of the core body 102 can be a catch and the engagement feature 164 of the mating interface part 160 can be a tab or protrusion that slidably and removably engages with the catch 146 of the core body 102. In other examples, the engagement features 146 and 164 can be any type of known mechanical engagement. An interface shield 166 ( FIG. 2 ) can be provided that surrounds the mating interface part 160 and electrically and mechanically connects with the shield 108.

[0033] One aspect of the disclosure is a method of manufacturing or assembling a network connector, such as the connector 100. The method may include mounting a plurality of contacts 104a, 104b onto a core body 102 of the connector 100, mounting a magnetic isolation component 110 onto the core body 102, and coupling an internal printed circuit board 106 to the plurality of contacts 104a, 104b of the core body 102. A shield 108 may be assembled over a subassembly 101 of the core body 102, the plurality of contacts 104a, 104b, the magnetic isolation component 110, and the internal printed circuit board 106, such that the shield 108 partially or substantially surrounds the subassembly 101 to provide a shield.

[0034] The method may also include inserting the subassembly 101 into the housing shell 150 by inserting the subassembly 101 through the rear end 153 of the housing shell 150 prior to assembling the shield 108 onto the subassembly 101. The method may also include coupling a mating interface piece 160 with the front end 120 of the core body 102 using corresponding engagement features 146 and 164, and coupling the internal printed circuit board 106 to mating contacts 162 of the mating interface piece 160.

[0035] The individual contacts 104a, 140b may be mounted to the core body 102 through holes 142 (FIG. 7A) for an interference fit between the contacts 104a, 140b and the core body 102. The magnetic cores 112 and 114 of the magnetic isolation component 110 may be mounted in pairs on one or both of the side support surfaces 126a and 126b of the middle portion 124 of the core body 102. In one example, four pairs of cores 112, 114 paired together may be mounted on the core body 102. For example, two pairs of cores 112, 114 paired together may be mounted in each cavity 144a, 144b of each side support surface 126a and 126b. In another example, all four pairs of cores 112, 114 paired together may be mounted on only one of the side support surfaces 126a and 126b of the core body 102. In a further example, any number of cores 112 and 114, or any number of cores 112, 114 paired together, may be mounted to one or both of the side support surfaces 126a and 126b of the core body 102. The paired together cores 112 and 114 are connected to the first set of contacts 104a and the second set of contacts 104b via wires 116a, with the magnetic cores 112 and 114 between the first set of contacts 104a and the second set of contacts 104b, as shown in Figure 9. In one example, the wires 116a may be soldered to the contacts 104a, 104b.

[0036] The mating interface part 160 is coupled to the front end 120 of the core body 102 by engaging the respective engagement features 146 and 164. The internal circuit board 106 is positioned on the top 128 of the core body 102 and coupled to both the exposed ends 132 of the first set of contacts 104a and to the mating contacts 162 of the mating interface part 160. The subassembly 101 of the core body 102 with the contacts 104a, 104b, the mating interface part 160 on the front end 120 of the core body 102, and the internal printed circuit board 106 on the top 128 is inserted into the housing shell 150 via the open rear end 153 of the housing shell 150. A mating shield 166 is added to the mating interface piece 160, and a bottom cover 156 is added to the open bottom 154 of the housing shell 150, with the exposed ends 134 of the second set of contacts 104b extending through the bottom cover 156. Finally, the shield 108 can be assembled over the housing shell 150 to cover or partially cover the housing shell 150, including the open rear end 153 of the housing shell 150.

[0037] 8A and 8B show left and right side views, respectively, of the core body 102, showing the first and second sets of contacts 104a and 104b supported by the core body 102, and showing the pin numbering of the exposed portions 132 and 134 of the contacts 104a, 104b. FIG. 9 is a schematic diagram of the circuit through the connector 100 between the main printed circuit board 10 (also referred to as the "printed circuit board side") and each of the mating connectors 12 (also referred to as the "mating connector side"). The circuit path shown in FIG. 9 corresponds to the pin numbering of the contact posts 132 and 134 shown in FIGS. 8A and 8B. The magnetic cores 112 and 114, when wrapped with the wire 116a, provide a signal filter for the signal path between the first set of contacts 104a and the second set of contacts 104b to meet the insulation requirements of current Ethernet standards. For example, four channels CHA, CHB, CHC, and CHD (required for 10GBASE-T Ethernet) may be provided for the circuit path. A channel is one of the differential signal pairs that carry signals between a main printed circuit board 10 and a mating connector side 12, such as a cable plug. Each channel CHA, CHB, CHC, and CHD includes one pair of cores 112 and 114 paired together, with a wire 116a wrapped around it, as seen in FIG. 9. In one example, three wires 116a may be wrapped around the cores 112 and 114 in each of channels CHA, CHB, CHC, and CHD. In other examples, more or less than three wires may be used in each channel. In one example, for speeds of 1000BASE-T and above, four differential pairs / channels are used for each connector 100, where the four channels can correspond to a typical network cable for Ethernet (i.e., mating connector on mating connector side 12) that has four twisted / differential pairs (a total of eight wires). In other examples, more or less than four channels can be used in the signal path of connector 100.

[0038] One end 117 (also referred to as the “first end”) of each wire 116a is electrically and mechanically coupled to an exposed portion or post 132 of the first set of contacts 104a. The other end 119 (also referred to as the “second end”) of each wire 116a is electrically and mechanically coupled to an exposed portion or post 134 of the second set of contacts 104b. In one example, the first and second ends 117 and 119 of each of the wires 116a may be soldered to the respective contact posts 132 and 134.

[0039] In operation, signals are transmitted from the main printed circuit board 10 through the connector 100 between the mating connector (mating connector side 12) coupled to the connector 100 at the mating interface 160 of the connector 100. The signal from the printed circuit board side 10 is received by the exposed portion 134 of the second set of contacts 104b (electrically connected to the board 10 and mounted on the core body 102) and then connected via wire 116a to the exposed portion 132 of the first set of contacts 104a for electrical connection with the internal printed circuit board 106. Between the connection of the wire to the contact 104b and the contact 104a, the wire is wrapped around a magnetic isolation component 110 (e.g., magnetic isolation cores 112, 114) that filters the signal as described above. The signal is then received by the mating interface component 160 from the internal circuit board 106, via mating contacts 162 electrically coupled to the internal printed circuit board 106, which is coupled (electrically and mechanically) to a mating connector on the mating connector side 12, which in turn receives the signal. The signal may travel through the connector 100 between the main printed circuit board 10 and the mating connector side 12 along a signal path through channels CHA, CHB, CHC, and CHD. For example, a signal from the printed circuit board side 10 can travel through channels CHA, CHB, CHC, and CHD via exposed contact portion or post 134, through the second end 119 of wire 116a (coupled to post 134), through the magnetic isolation component 110 including the pair of cores 112 and 114 around which wire 116a is wound, through the first end 117 of wire 116a, to the exposed contact portion or post 132 (to which first end 117 is coupled), and then to the mating connector side 12.

[0040] In one aspect, the connector 100 may be configured to provide power from the mating connector side 12 to the printed circuit board side 10. In one example, one or more wires 116b (also referred to as "power wires") for receiving and transmitting power may be included in the subassembly 101. Each power wire 116b may be coupled (electrically and mechanically) between exposed portions 132 and 134 of the first and second sets of contacts 104a and 104b on the core body 102, as seen in FIGS. 6, 8A, and 8B. The power wires 116b are separate from the wires 116a and are not associated with the magnetic isolation component 110. Rather, the power wires 116b provide a direct power line between the first set of contacts 104a and the second set of contacts 104b. 9, the power wire 116b may directly connect pins number 8 and 26 of the first and second sets of contacts 104a and 104b, may directly connect pins number 9 and 27, may directly connect pins number 17 and 35, and may directly connect pins number 18 and 36. In one example, the power wire 116b is disposed on the core body 102 near the rear end 122 of the core body 102. Thus, the power wire 116b provides a power line (separate from the signal path) between the main printed circuit board 10 and the mating connector side 12 to provide Power over Ethernet capability.

[0041] In another embodiment, one or more ground wires 116c may be provided on the core body 102 to connect to a ground plane of the main printed circuit board 10. Each ground wire 116c may also be coupled between the exposed portions 132 and 134 of the first and second sets of contacts 104a and 104b, as seen in FIGS. 6, 8A, and 8B, and may be positioned near the rear end 122 of the core body 102 separately from the wires 116a. The ground wires 116c are separate from the wires 116a and the power wires 116b, and are not associated with the magnetic isolation component 110. Rather, the ground wires 116c provide a direct ground path between the first set of contacts 104a and the second set of contacts 104b. For example, the ground wires 116c may directly connect pins 7 and 25, as seen in FIG. 9, and may directly connect pins 16 and 34 of the first and second sets of contacts 104a and 104b.

[0042] FIG. 10 shows some of the connectors 100 mounted on a main external printed circuit board 10. The pitch P between the connectors 100 is defined as the distance between the centerlines of each of two adjacent connectors 100. An advantage of some examples is that if space on the main printed circuit board 10 is limited, the pitch P between the connectors 100 can be minimized while also integrating the required magnets into each of the connectors 100 on the board 10. Another advantage is that more space is available on the board 10 since the required magnets no longer take up space on the board, but are instead integrated into each of the connectors 100. Yet another advantage is that it eliminates the step of having to mount the required magnets on the board in addition to mounting the connectors 100, since the magnets are already integrated into each connector 100. In one example, the pitch P can be maintained in a range of about 9 mm to 14 mm, in a range of about 10 mm to 12 mm, in a range of about 10 mm to 11 mm, or can be maintained at 10 mm or less, or about 10 mm.

[0043] In one example, connector 100 may have a similar configuration to a conventional IX INDUSTRIAL connector and may be used in place of a conventional IX INDUSTRIAL connector, and because a conventional IX INDUSTRIAL connector lacks an isolation transformer, using connector 100 in place of the conventional IX INDUSTRIAL connector eliminates the need to provide or mount such a transformer on a printed circuit board.
