Description

FIELD OF THE INVENTION

The present invention generally relates to connecting twisted conductor pairs of a communications connector.

BACKGROUND OF THE INVENTION

As is known, communications patch panels frequently incorporate the use of jack modules, like that shown at 100 in FIG. 1, that can be readily attached to and removed from the patch panel. Typically, existing jack modules 100 include a housing 102 having a front portion 104 and a back portion 110. The front portion 104 is visible to the user of the patch panel and includes one or more jack openings 106 configured to receive a communication connector (not shown). The front and back portions 104, 110 engage and mate with each other and serve to protect internal components, such as a printed wiring board 130, one or more jack receptacles 136, and/or a plurality of insulation displacement connectors (IDCs) 138. The jack receptacles 136 are mounted to the front side 132 of the printed wiring board 130, while the IDCs 138 are mounted to the back side 134. Traces (not shown) on the printed wiring board 130 electrically connect the IDCs 138 to electrical contacts 137 (see FIG. 2) housed within the jack receptacles 136. As assembled, each jack receptacle 136 aligns with a jack opening 106 in the front portion 104 of the housing 102, and the IDCs 138 are aligned with a terminal connection region 112 disposed on the back portion 110. As shown, the front portion 104 and the back portion 110 of the housing are secured together with assembly tabs 108 on the front portion 104 that engage assembly notches 109 on the back portion 110.

FIG. 2 illustrates the jack module 100 as it would be seen by a user of a typical communications patch panel. FIGS. 3 and 4 show the terminal connection region 112 in greater detail. As shown in FIG. 4, the terminal connection region 112 includes two substantially parallel rows 114 of alternating wire guide posts 116 and wire guide splitters 117. As best seen in FIG. 3, adjacent wire guide posts 116 and wire guide splitters 117 have a terminal slot 118 disposed therebetween. Each terminal slot 118 provides access to one of the IDCs 138 disposed within the parallel rows 114. Physical and electrical contact is made between a conductor (not shown) and an IDC 138 by urging the conductor into the terminal slot 118 until the conductor passes between the opposed prongs 139 of the IDC (FIG. 1). Opposed portions of the prongs 139 cut through insulation disposed around the conductor, thereby making electrical contact.

To electrically connect a cable including a plurality of twisted pairs to an existing jack module 100, first a technician determines which IDCs 138 are associated with the desired jack receptacle 136 (see FIGS. 1 and 4). In FIG. 1, the IDCs of interest are accessed by way of the pairs of terminal slots labeled 115a, 118b, 118c, and 118d, each of the pairs of the terminal slots 118 being configured to receive the conductors from one of the cable's twisted conductor pairs. Once the desired IDCs 138 have been determined, the technician urges the desired conductor into the appropriate IDC, typically using a device such as a punch-down tool. As shown, one twisted pair would be inserted into each pair of terminal slots 118a-118d. The wire guide splitters 117 assist the technician in separating the conductors of each twisted conductor pair, thereby making it easier for the technician to insert the desired conductor into the desired IDC 138.

Until recently, such methods of routing twisted pairs on the back of existing jack modules 100 were adequate for existing performance levels. This was because in the past variation of the routing of twisted pairs, from pair to pair, had little effect, if any, on performance. However recent developments, such as patch panels requiring category 6 performance levels, are much more sensitive to variations in twisted pair termination and routing. One approach to reducing variation in termination and routing is illustrated in U.S. Pat. No. 6,767,241 to Abel et al., the disclosure of which is hereby incorporated herein in its entirety. This patent discusses a termination cap that receives the conductors from the cable, then routes the conductors through apertures and slots in the cap in an organized fashion. The cap is attached to the back portion of the jack module, at which time the organized conductors can be routed to their respective IDCs. Another proposed solution is discussed in U.S. patent application Ser. No. 11/360,733; filed Feb. 23, 2006 and entitled Device for Managing Termination of Conductors with Jack Modules, the disclosure of which is hereby incorporated herein by reference. The device discussed therein includes a block with upper and lower surfaces, first and second opposing end walls that define a longitudinal axis, and first and second opposing side walls. The block further includes two apertures extending from the upper surface toward the lower surface, the apertures being sized and configured to receive each of the plurality of twisted pairs of a cable. Each of the side walls includes at least one open-ended slot opening downwardly, the slots being sized and configured to receive a respective twisted pair of conductors and hold them in place. From there the conductors can be punched into place with a punch tool to connect to the IDCs of a terminal connection region.

Although these solutions are adequate, it may in some instances be desirable to provide even more control of the positions of the conductors in order to further reduce variation in their seating with the IDCs, which in turn can improve electrical performance and reliability. It may also be desirable to simplify the interconnection process between the cable and the IDCs.

Referring now to the figures, a termination device, designated broadly at 200, is illustrated in FIGS. 5 and 6. The device 200 includes a body 202 that is generally cylindrical and defined by an outer wall 204. A circumferential flange 206 extends from one end of the body 202. Also, a central bore 203, shown herein as being generally square, extends along the longitudinal axis A of the body 202.

Referring again to FIGS. 5 and 6, four pairs of channel walls 207a, 207b extend radially outwardly from the body 202. Each pair of channel walls 207a, 207b lines a respective open-ended channel 208 that extends generally parallel to the longitudinal axis A and recedes radially inwardly into the body 202. The channels 208 are generally spaced circumferentially equidistant from each other (i.e., in this embodiment having four channels 208, the channels 208 are spaced approximately 90 degrees from each other about the longitudinal axis of the body 202). The channel walls 207a, 207b and the channel 208 are shaped such that at each end the channel 208 has a respective narrow necked portion 212a, 212b, and at its center the channel 208 has an expanded portion 210. Also, the floor of the channel 208 has curved indentations 209a, 209b that are arcuate in cross-section. A looped hook 214 is positioned over the necked portion 212a. In some embodiments, the channel 208 is between about 0.230 and 0.270 inches in length and/or between about 0.125 and 0.145 inches in depth, with the necked portions 212a, 212b being between about 0.043 and 0.053 inches in width and the expanded portion 210 being between about 0.087 and 0.097 inches in width.

Referring still to FIGS. 5 and 6, the channel walls 207a, 207b between adjacent channels 208 form pockets 216 that are open on one end (the other end being closed by the flange 206). Two circumferentially-extending blade slots 218a, 218b are located in the channel walls 207a, 207b near the necked portions 212a, 212b, the slots 218a, 218b being generally normal relative to the longitudinal axis A.

In the illustrated embodiment, the device 200 is formed as a unitary member. In some embodiments, the device is formed of a polymeric material, such as polycarbonate or ABS.

Referring now to FIGS. 7 and 8, the device 200 is shown engaging a twisted pair of conductors 230a, 230b of a cable 229. The cable 229 may be a typical twisted pair cable, the construction and operation of which are well-known to those skilled in this art and need not be described in detail herein. The conductors 230a, 230b are twisted such that each twist 232 has a length of between about 0.200 and 0.220 inches. As used herein, a “twist” of a twisted pair of conductors refers to a segment of the twisted pair between crossover points; thus, looking at the twisted pair as a double helix, a “twist” would extend for approximately 180 degrees, or one-half revolution, of the conductors. The twist size or rate may vary for some or all of the twisted pairs of the cable 229. The twist 232 and channel 208 (including the indentations 209a, 209b) are sized such that the crossover points 234a, 234b of the twist 232 (in which one conductor overlies the other conductor) reside in the necked portions 212a, 212b of the channel 208. As a result, in the necked portion 212a, the conductor 230b is positioned radially outwardly from the conductor 230a (and therefore, at a shallower depth in the channel 208), and in the necked portion 212b, the conductor 230a is positioned radially outwardly from the conductor 230b. Conversely, in the expanded area 210, the conductors 230a, 230b lie generally side-by-side. The hook 214 deflects away from the channel 208 upon insertion of the conductors 230a, 230b but recovers to engage the crossing point 234a in order to help to maintain the conductors 230a, 230b in place in the channel 208.

The interconnection of the conductors 230a, 230b to mating IDCs can be understood with reference to FIGS. 9-14. Four pairs of IDC blades 240, 242 (only one pair of which is shown in FIGS. 9-14) are mounted in a housing 238 which includes an aperture 239 of sufficient size to receive the device 200. The housing 238 may be a portion of a patch panel, a Jack outlet, or other device to which twisted pair conductors are typically connected. For example, the housing 238 may be the back portion 110 of the jack module 100 shown in FIGS. 1 and 4 modified to have apertures 239 and blades 240, 242. Each pair of blades 240, 242 is mounted in generally stacked, spaced apart alignment, with the four pairs being generally equally circumferentially spaced from each other, such that they extend into the aperture 239 (see FIGS. 13 and 14).

The device 200 is inserted into the aperture 239 by orienting the longitudinal axis A of the device 200 to be collinear with the longitudinal axis of the aperture 239 (FIG. 9). The device 200 is then pushed into the aperture 239 such that the pairs of blades 240, 242 are received in respective pockets 216 (FIGS. 10 and 11). Once the blades 240, 242 are aligned with the slots 218 in the device 200 (FIGS. 10 and 11), the device 200 is then rotated within the aperture 239 (clockwise from the vantage point of FIGS. 12-14) about its longitudinal axis until the blades 240, 242 slide into the slots 218a, 218b to engage, respectively, the conductors 230a, 230b. This rotation can be facilitated with the use of a tool, for example, a square-headed driver, that is inserted into the central bore 203 of the device 200. Upon engagement with the conductors 230a, 230b, the blades 240, 242 pierce the insulation of the conductors 230a, 230b and engage the conductive portion of the conductors at engagement locations 246, 248 (FIGS. 12 and 14).

As can be seen in FIG. 14, rotation of the device 200 causes the blades 240, 242 to engage the conductors 230a, 230b. The blades 240, 242 extend radially inwardly only a sufficient distance to engage the “top” or radially outwardly positioned conductor 230a, 230b at the respective necked portion 212a, 212b. Because the channel 208 is sized and configured to receive one twist of a pair of conductors, opposite conductors are on “top” at opposite ends of the channel 208. Thus, at the necked portion 212a, the blade 240 engages and makes electrical contact with the conductor 230a without making electrical contact with the conductor 230b. The reverse is true at the opposite necked portion 212b, where the blade 242 contacts and makes electrical contact only with the conductor 230b without making electrical contact with the conductor 230a.

The device 200 can be advantageous for multiple reasons. First, it enables the connection of one conductor of each twisted pair of conductors to one blade of a pair of IDC blades for multiple different pairs of conductors with a single movement of the device 200. Second, because each channel 208 is configured to receive a single twist of the conductors 230a, 230b and the engagement locations 246, 248 are positioned in the twist 234 (i.e., within the channel 208), the positions of these conductors are very predictable, which can assist in attempting to control the electrical properties of the conductors and the IDCs (such as crosstalk).

Those skilled in this art will recognize that the device 200 may take other forms that receive a single twist of conductors and/or permit the interconnection of multiple pairs of conductors at once within the length of the twist. For example, a square or rectangular device with two pairs of conductors retained on opposite sides may be inserted into an aperture in a housing slid sideways to engage IDCs mounted in a housing.

Alternatively, a single twist of conductors may be presented on the bottom surface of a device, and the device could be punched into IDC blades oriented and positioned to accept such twists. As another alternative, the blades of a pair of IDCs may be positioned on opposite sides of the channel that houses the twist of conductors, and the IDCs may engage the conductors in the expanded portion of the channel rather than adjacent the necked portions.

An alternative embodiment of a device having these two features is illustrated in FIG. 15 and designated broadly at 300. The device 300 includes a body 302 with a lower surface 304. Four channels 308 are recessed into the bottom surface 304. Each of the channels 308 includes curved indentations 309a, 309b, which define an expanded portion 310 and necked portions 312a, 312b. Each of the channels 308 also includes indentations 318a, 318b that are configured to receive IDC blades 340, 342.

As can be seen in FIG. 15, a pair of conductors 330a, 330b is inserted through an aperture 303 and received in the upper right-hand channel 308, with each of the conductors 330a, 330b residing in a respective indentation 309a, 309b. Crossover points 334a, 334b of the conductors 330a, 330b are received in the necked portions 312a, 312b. When one or more pairs of conductors have been received in their respective channels, the device 300 can be inserted into a receiving aperture in a mating housing that includes IDC blades 340, 342. As can be seen in FIG. 15, each of the IDC blades 340, 342 engages a respective conductor 330a, 330b within the twist of the conductors.

As with the device 200, the device 300 can advantageously enable the connection of one conductor of each twisted pair conductors to one blade of a pair of IDC blades for multiple different pairs of conductors with a single movement of the device 300. Also, because each channel is configured to receive a single twist of the conductors, and the engagement locations are positioned within the twist, the positions of the conductors, and in turn the positions of the engagement locations, are very predictable, which is conducive to controlling electoral properties of the conductors and the IDCs.

As a further alternative, the guide slots 218a, 218b and/or indentations 318a, 318b may be omitted entirely, or the another IDC guide structure, such as guide pins or posts or even use of the flange 206 to register the positions of the IDC blades, may be employed. An additional embodiment may include a channel that does not taper between the expanded portion and the necked portions, but instead is generally rectangular with narrowed slots at either end.

The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims.
