BACKGROUNDThe present disclosure relates to interconnect technology. More specifically, the present disclosure relates to interconnect technology used in electrical and optical systems.
Recently, there has been unprecedented growth in communication networks. In such highly competitive markets, network providers continuously struggle to find better ways to improve the quality of service at a lower cost.
One way in which network providers have tried to improve the quality of service while reducing cost has been to deploy high density interconnect panels. Data, voice, and other communication networks are increasingly using interconnect to carry information. High-density panels are designed to consolidate the increasing volume of interconnections necessary to support the fast-growing networks into a compacted form factor, thereby increasing quality of service and decreasing costs such as floor space and support overhead. However, the deployment of high-density interconnect panels has not fully realized the stated goals.
In communication networks, such as data centers and switching networks, numerous interconnections between mating connectors are compacted into high-density panels. Panel and connector manufacturers optimize for such high densities by shrinking the connector size and/or the spacing between adjacent connectors on the panel. While both approaches are effective ways by which to increase the panel connector density, shrinking the connector size and/or spacing increases the support cost and diminishes the quality of service.
A cable is generally constructed using a transmission medium such as an optical fiber or an electrical conductor. An electrical conductor is generally a copper wire configured to carry electrical power. An optical fiber is generally a glass fiber configured to carry light. Individual cables may be grouped into a line capable of carrying large amounts of data simultaneously. When constructing a communication network, a cable assembly typically includes a jacket to protect the underlying cable, and terminating connectors at each end of the cable. These terminating connectors may be used to optically and/or electrically couple a first cable assembly to a mating connector of a second cable assembly.
A typical connector may include a latching mechanism adapted to lock the engagement of a latching connector with a mating connector, and a release mechanism adapted to disengage the first latching connector from the mating connector. In the engaged configuration, an operator may disengage the engaged connectors by applying a vertical force upon the release mechanism by squeezing the release mechanism between the operator's thumb and forefinger.
In a high-density panel configuration, adjacent connectors and cable assemblies obstruct access to the individual release mechanisms. This physical obstruction impedes the ability for the operator to minimize the stresses applied to the cables and connectors. For example, these stresses may be applied when the user reaches into a dense group of connectors and pushes aside surrounding optical fibers and connectors to access an individual connector release mechanism with the thumb and forefinger. Overstressing the cables and connectors may introduce latent defects, compromise the integrity and/or reliability of the terminations, and potentially cause serious disruptions to the network performance.
While an operator may attempt to use a tool, such as a screwdriver, to reach into the dense group of connectors, and activate the release mechanism, the adjacent cables and connectors can obstruct the operator's line of sight, making it difficult to guide the tool to the release mechanism without pushing aside the surrounding cables. Moreover, even when the operator has a clear line of sight, guiding the tool to the release mechanism is a time consuming process. Therefore using a tool is not effective at reducing support time and increasing the quality of service.
Quality of service and support time is further disadvantaged by exposure of the cable termination to the surrounding environment, and vulnerability of being scratched, chipped, cracked, or otherwise damaged by dust particles, grease, contaminants, and other foreign objects when the operator disengages the release mechanism. Such damage to the cable may potentially cause serious disruption to the network performance. While dust covers may be used to prevent such damage, small and loose hardware, such as dust covers, bears the tendency to become lost, misplaced, or otherwise not easily accessible to the operator when it is needed.

It should thus be clear that the dimensions of themating connectors150 or thecouplers120, as well as the distances in apanel100, on each side of themating connector150 orcoupler150, may vary dependent on the design.
Referring toFIGS.3A and3B, a push-pull cable assembly200 is configured to connect to themating connector150. The push-pull cable assembly200 generally includes acable assembly connector210, anadaptive release member240, and anextender260.
Referring also toFIG.4, thecable assembly connector210 includes a latching connector216, atransmission medium212, and ajacket218. The latching connector216 includes anouter housing220, aninner housing214, alever222, front stops228, and rear stops230. Thetransmission medium212 is concentrically disposed within theinner housing214 and thejacket218. Thetransmission medium212 can comprise an optical fiber or an electrical conductor. A first end of thelever222 is attached to theouter housing220. A second end of thelever222 is not attached to theouter housing220. The lever includes latches224 and an extending member226 for extending thelever222. The latches224 are symmetrically attached to and protrude from both sides of thelever222. The extending member226 is attached to the second end of thelever222, and comprises a loop. Front stops228 and rear stops230 are attached to and protrude from theouter housing220, and are symmetrically disposed along both sides of theouter housing220.
Theadaptive release member240 includes and is attached toguides242, a release252, atab248, and snapbearings250. Eachguide242 is symmetrically disposed on theadaptive release member240, protruding downwardly from theadaptive release member240 bottom surface for a length that is approximately equal to the height of theouter housing220, and curves inwardly towards the center of theadaptive release member240. The release252 includes alever space244. Thelever space244 is generally sufficiently wide enough to accommodate the width of the extending member226. The release252 also includes and is attached tosymmetrical release members246. Each of therelease members246 protrude inwardly into thelever space244, collectively forming a channel that is narrower than the width of the extending member226. Thetab248 protrudes from the top surface of theadaptive release member240. Thesnap bearings250 are symmetrically disposed on both sides of theadaptive release member240.
Theextender260 includes and is attached to an actuator261, ridges266, ajacket clamp274, and a dust cover272. The actuator261 includes snaps264 and a slot262. The slot is sized to cooperate with thetab248. The snaps264 protrude symmetrically on each side of theextender260 and are sized to cooperate with thesnap bearings250. Each ridge266 protrudes downwardly from the bottom side of theextender260. A groove268 is disposed between each pair of successive ridges266. The dust cover bearing270 is appropriately sized to cooperate with the dust cover272. The dust cover272 has an outer diameter that is appropriately sized to fit inside the housinginner surface214, and includes a cavity276 which is appropriately sized to accommodate the diameter of thetransmission medium212. The dust cover272 base is attached to a pair oflips278. Thelips278 protrude outwardly along the circumference of the dust cover272. Thelips278 are spaced to cooperate with the dust cover bearing270 thickness. Thejacket clamp274 is sized to accommodate the diameter of thejacket218.
The inner andouter housings214 and220 are configured to engage with amating connector150 along acoupling direction206. Thetransmission medium212 acts as a conduit to carry a signal over a distance spanning the length of thetransmission medium212. Thejacket218 protects thetransmission medium212 from damage during operation. Thelever222 is configured to receive a force in a direction normal to the top of theouter housing220 and to transmit a proportionate force acting in the same direction to the latches224, thereby selectively disengaging the latching connector216 from themating connector150.
Theadaptive release member240 is configured to receive a force opposite to thecoupling direction206, and to disengage the latching connector216 from themating connector150 by transmitting a component of the received force to the latching connector216. Therelease members246 are configured to cooperate with the extending members226 to compress thelever222. Thelever space244 is configured to provide a resting space for thelever222. Theguides242 cooperate with theouter housing220, front stops228 and rear stops230 in order to restrict the release252 range of motion to thecoupling axis205 of the latching connector216 and to further restrict theadaptive release member240 range of motion to the space between front stops228 and the rear stops230. Thetab248 and thesnap bearings250 mechanically couple with corresponding structures of the slot262 and the snaps264. Thesnap bearings250 cooperate with the snaps264 to provide freedom for theextender260 to move in the direction normal to thecoupling axis205.
While the extending member226 comprises a loop in this particular design, it should be understood that the extending member226 can comprise any other shape which cooperates the release252 to compress of thelever222.
Theextender260 includes an actuator261 that is configured to receive a force that is opposite to thecoupling direction206, and to transmit a component of the received force to theadaptive release member240. The ridges266 and the grooves268 provide enhanced flexibility along the length of theextender260. Thejacket clamp274 is configured to clamp thejacket218 and to prevent theextender260 from dangling. The dust cover bearing270 receives and holds the dust cover272 in place. The dust cover272 plugs the cavity between thetransmission medium212 and the housinginner surface214, thus protecting thetransmission medium212 when it is not in use.
Referring again toFIGS.2A and2B, themating connector150 receives the latching connector216 of thecable assembly200. An operator may engage the latching connector216 with themating connector150 by guiding the leading edge of the latching connector216 into themating connector150 and applying a force in thecoupling direction206. The operator applied force in turn causes the top inner surface of themating connector150 to compress thelever222, and thereby align the leading edge of each latch224 between the respectivetop rail170 andbottom rail180. When the trailing edge of each latch224 then crosses the interface between the respectivetop rail170 andbottom rail180, each latch224 becomes sandwiched in between the respectivetop rail170 andbottom rail180 thereby maintaining thelever222 in the compressed position. When the trailing edge of each latch224 crosses into therespective trap190, thelever222 becomes decompressed, thereby trapping thelever222 in thetraps190. In this trapped position, the latching connector216 is said to be engaged with themating connector150.
Thecable assembly200 is disengaged from themating connector150 by applying a force that is opposite to thecoupling direction206, to theextender260 until the latching connector216 disengages from themating connector150. Theextender260 transmits a component of this force to theadaptive release member240. Theadaptive release member240 in turn transmits a component of this force to theguides242 and to therelease members246. Accordingly, therelease members246 cooperate with the extending members226 to compress thelever222 until each of the latches224 are aligned between the respectivetop rail170 andbottom rail180. The leading edge of each latch224 then crosses the interface between the respectivetop rail170 andbottom rail180, freeing thelever222 from thetraps190. In this position, thetop rail170 and thebottom rail180 compresses thelever222, and the latching connector216 is said to be disengaged from themating connector150. The force guides the latching connector216 outside of themating connector150. In this disengaged position, thetransmission medium212 can be protected by folding theextender260 over and plugging the dust cover272 in the cavity between thetransmission medium212 and the housinginner surface214.
Referring toFIG.5, thecouplers120 are engaged with an array ofcable assemblies200. The push-pull cable assembly100 permits the spacing ofcouplers120 to be in close proximity to each other.
Referring toFIGS.6A and6B, a multi-port push-pull cable assembly300 can generally include amulti-port cable assembly310, anadaptive release member340, and anextender360.
Themulti-port cable assembly310 includes a plurality ofcable assemblies310a and310b.Cable assemblies310a and310b each can generally include a latchingconnector316, a transmission medium312, and ajacket318. The latchingconnector316 includes anouter housing320, aninner housing314, a lever322, front stops328, and rear stops330. The transmission medium312 is concentrically disposed within theinner housing314 and thejacket318. The transmission medium312 can comprise an optical fiber or an electrical conductor. A first end of the lever322 is attached to theouter housing320. A second end of the lever322 is not attached to theouter housing320. The lever includes latches324 and an extendingmember326 for extending the lever322. The latches324 are symmetrically attached to and protrude from both sides of the lever322. The extendingmember326 is attached to the second end of the lever322, and comprises a loop. Front stops328 andrear stops330 are attached to and protrude from theouter housing320, and are symmetrically disposed along both sides of theouter housing320.
