Definitions

  • the present invention relates to an electrical connector for use in telecommunications.
  • Telecommunications utilities provide a network of cables through which the calls they handle can be routed. These cables can be of optical fibre or conductive copper, but the end of the network close to the subscriber is usually copper. As the network is usually of necessity laid prior to application for service by subscribers, it is necessary to provide a flexible network which can be reconfigured as required by the pattern of subscribers, and to allow for disconnection, reconnection, and connection of new subscribers.
  • the usual practice of a utility when laying a new local network is to install a multi-pair cable, such as a 400 pair cable, from the exchange past a number of distribution points. Each individual pair is accessible at several distribution points, so the resulting network is highly flexible. This practice is acceptable for voice telephony and low speed data use.
  • a distribution point is typically housed in a cabinet at the roadside, although other arrangements are used, and contains an array of connectors at which wire pairs leading to the consumer premises can be attached to form a spur.
  • Each spur is tapped into a pair of the cable, enabling service to be provided. If that service is discontinued, the relevant spur is removed and the connector becomes available for use in providing service to another consumer.
  • US-A-6,031,300 shows a system for mixed telephony and co-axial cabling in which a rotary switch is used on the connectors for co-axial cables to disconnect this spur.
  • US-A-5,802,170 discloses a customer bridge module for connecting telephone company wiring and subscriber telephone wiring in a telephone network interface apparatus, the customer bridge module having a plug-actuated switchable socket and an overcurrent protection circuit, a half-ringer, a maintenance termination unit or a radio frequency interference (RFI) filter.
  • RFID radio frequency interference
  • the present invention therefore provides a telecommunications connector as set out in claim 1.
  • the configuration module can also contain protective devices for the line, such as three or five pin protection, over current devices and over voltage devices, or other active electronic elements such as (but not limited to) line termination devices, remote identification devices, and so on.
  • protective devices for the line such as three or five pin protection, over current devices and over voltage devices, or other active electronic elements such as (but not limited to) line termination devices, remote identification devices, and so on.
  • the configuration module causes electrical connection between the exchange and consumer to be broken.
  • the exchange is always connected to either a consumer or a further distribution point (except at the last), but potentially never both.
  • a removable configuration module can thus be provided with seven electrical connections, being two each for the pairs leading to the exchange, further distribution point and consumer, together with an earth.
  • the present invention also relates to such a seven pin protector module for a telecommunications line.
  • the present invention also relates to a five pin protector module for a telecommunications line which is adapted to seat in a seven pin socket of a base unit.
  • designs with less than 7 pins or more than 7 pins in the base unit are again possible.
  • a typical local network includes a 400-pair cable 100 which enters the area to be served and splits into branch cables such as 102 which contain a lesser number of pairs.
  • Each branch cable is connected to a number of distribution points such as those at 104 and 106.
  • the cable branches repeatedly at branch points such as 108 so as to serve a large number of such distribution points.
  • An individual pair, such as (for example) pair number 81 of the 400 may itself branch at a number of such branching points 108 and be made available at a number of distribution points on that branch and on other branches.
  • Figure 1 shows the pair numbers which (in this example) are made available on each branch or segment of the line.
  • the distribution points at which pair no. 81 is available are indicated with a *. It will be seen that this pair is available at six distribution points and branches twice along its length.
  • FIG. 2 shows the typical electrical structure at a distribution point.
  • a wire pair 112 enters the distribution point and continues on through and out as 114.
  • Electrical connections 116 are made with each wire of the pair and brought to a connector 118 which is usually of the insulation displacement type (IDC).
  • IDC insulation displacement type
  • FIGS. 3 and 4 illustrate the principle behind the present invention.
  • a wire pair 112' enters the distribution point and departs as wire pair 114'. However, the two wire pairs are not connected together directly but instead each end at connecters 122, 124 respectively.
  • a consumer pair 120' also leaves the distribution point for the subscriber's premises but is connected to a third connector 126.
  • a configuration module is connectable to any or all of the three connectors 122, 124, 126 and contains a pair of bridging links which are able to bridge appropriate pairs. In this position illustrated at figure 3, the bridging links 128 bridge connections 122 and 124 and therefore link the incoming wire pair 122' with the outgoing wire pair 114'.
  • the subscriber pair 120' is left unconnected.
  • the conductors 128 of the configuration unit bridge connecters 122 and 126 thereby connecting the subscriber pair 120' to the incoming wire pair 112'. It is to be assumed that the incoming wire pair 112' is from the exchange and the outgoing wire pair 114' is to a further distribution point. Thus, in this disposition, the subscriber is connected to the exchange but the "tail" of unused wire pair is left isolated, not forming part of the circuit to the subscriber.
  • FIGS. 5 to 9 show a first working example of how this might be put in practice.
  • the embodiment consists of two main parts, a base unit 200 shown in figure 6 and a configuration unit 202 showing in figures 7 and 10.
  • the base unit 200 contains seven conductors 204 which are accessible on the underside of the base unit 200 via IDC connectors. These are presented within a recess 206 on the upper surface of the base unit 200 as upstanding metal blades such as 208. Of the seven blades, six are parallel and arranged in pairs, one pair at one end of the recess 206, one pair at the opposite end of the recess 206 and the third pair at the centre of the recess.
  • the seventh blade 210 is presented at right angles at the centre of the recess 206 between a pair.
  • the central pair 212 is connected to the wire pair 112' from the exchange.
  • the pair of connectors 214 at one end of the recess are connected to the ongoing pair 114' leaving two further distribution points.
  • the pair of blades 216 at the other end of the recess 206 are connected to the subscriber pair 120'.
  • the configuration unit 202 contains two conductors 218, 220. These are spaced and arranged so that they will bridge the gap between either blades 212 and 214 or blades 212 and 216.
  • the mating surfaces between the base unit 200 and the configuration unit 202 are made symmetric under a rotation of 180° and therefore the configuration unit 202 can be placed in any one of two dispositions so as to effect connection between the appropriate set of blade pairs.
  • the configuration unit when placed in the first orientation the configuration unit causes the incoming wire pair or 112' from the exchange to be connected to the outgoing wire pair 114' to further distribution points.
  • the configuration unit 202 When inserted in a rotated disposition, the configuration unit 202 causes the incoming wire pair 112' to be connected to the subscriber 120 and disconnected from the outgoing wire pair 114'.
  • the principle illustrated in figures 3 and 4 is effected.
  • Figure 8 shows the base unit 200 with the conductors 218, 220 of the configuration unit 202 in place and the remainder of the configuration unit 202 cut away. It will be seen that the conductors make electrical contact on one side of the blades 208.
  • Figure 7 shows the two units connected but with all non-conducting parts removed. It can be seen that a three pole protection module 222 such as a gas discharge tube is connected at either end to the conductors 218, 220 and at its centre to a further conductor 224 which grips the sides of the earth contact 210. Thus, the configuration unit 202 is also able to offer protection to the line if desired. It will be seen that if protection is undesired for a particular line, the protection unit 222 can simply be omitted.
  • a three pole protection module 222 such as a gas discharge tube is connected at either end to the conductors 218, 220 and at its centre to a further conductor 224 which grips the sides of the earth contact 210.
  • the configuration unit 202 is also able to offer protection to the line if desired. It will be seen that if protection is undesired for a particular line, the protection unit 222 can simply be omitted.
  • Figure 9 shows the configuration unit 202 from above.
  • a pair of recesses 226, 228 are formed into which extend the ends of the conductors 218, 220.
  • the recesses 226, 228 would normally be filled with a gel, grease, or other conformable material to allow environmental protection. Nevertheless, such material can be penetrated by crocodile clips or test leads of various types thereby allowing test access to the port.
  • an engineer will be able to make temporary contact to the line to ascertain whether or not a call is in progress. If not, he can remove the configuration unit 202 and gain access to the three wire pairs therewithin. If testing of a central pair 212 reveals no connection to the exchange, the engineer can ascertain whether the pair has been disconnected at a distribution points closer to the exchange. The engineer can also test the quality of the line from blade 216 to the subscriber, thereby achieving "look both ways testing".
  • a base unit 300 contains a pair of conductors 302, 304.
  • the first conductor 302 consists of a first lower IDC contact 306 which projects from the lower face of the base unit 300 and a first upper split beam contact 308 which projects upwardly of the base unit 300.
  • the second conductor 304 consists of a second lower IDC contact 310 which also projects from the lower face of the base unit 300, a second upper split beam contact 312 which also projects upwardly of the base unit 300 adjacent to the first upper split beam contact, and a subscriber IDC contact 314 which projects upwardly of the base unit 300 at a location displaced from the second upper IDC contact 312.
  • the first and second upper split beam contacts 308,312 project upwardly of the base unit 300 by different lengths, the second (312) being shorter.
  • a mating face 316 is formed on the upper surface of the base unit 300 around the first and second upper split beam contacts, enclosing them within a recess 318 so as to permit environmental protection by way of gel, grease or the like, and also supporting them so as to prevent unintended deformation during use.
  • a configuration module 320 is formed with a complementary mating face 322 to allow it to be joined to the base unit 300.
  • the mating faces 316, 322 are symmetrical under a 180° rotation and therefore the configuration unit can be attached in at least two dispositions.
  • the configuration module 320 contains a conductor 324 which has two legs 326, 328 extending towards the space enclosed by the mating face 322 of the configuration module 320.
  • the leg 328 is longer than the leg 326 by a length corresponding to the difference in length of the first and second upper split beam contacts 308, 312.
  • the subscriber IDC contact 314 may be supported appropriately in a suitable structure and provided with wire carrying structures to permit a wire to be inserted and removed as necessary.
  • wire carrying structures to permit a wire to be inserted and removed as necessary.
  • the precise structure of this is not germane to the present invention and will not be described in detail. Suitable structures are illustrated and described in our earlier patent publications GB 2129630 and EP0683925.
  • the base unit 300 is installed at a distribution point and a wire pair 330 from an exchange is attached to the second lower IDC contacts 310.
  • a wire pair 332 leading to a further distribution point is attached to the first lower IDC contacts 306.
  • the configuration unit 320 is attached via the mutual mating faces in a first disposition such that the longer leg 328 mates with the (shorter) second upper split beam contact 312 and the shorter leg 326 mates with the (longer) first upper split beam contact 308.
  • the wire pair 330 is connected to the wire pair 332 and the pair is in effect allowed to continue through the distribution point to a more distant distribution point.
  • a test probe can be attached to the subscriber IDC contact to ensure that a call is not then in progress. Assuming not, the configuration module is then removed, breaking the pair at that distribution point. A wire pair 334 leading to the subscriber's premises is then attached to the subscriber IDC contacts 314 and the configuration unit 320 replaced in a disposition which differs by a 180° rotation.
  • the longer leg 328 is above the first upper spilt beam contact 308 and makes contact therewith.
  • the first upper split beam contact 308 is designed so as to be able to accept the length of the leg 328.
  • the shorter leg is insufficiently long to meet the second upper split beam contact 312 and accordingly there is no electrical continuity between the conductors 302, 304.
  • the pair therefore remains broken at this distribution point, but in a reversible fashion since connection can be remade by replacing the configuration unit 320 in its original disposition.
  • the subscriber is nevertheless connected to the exchange since the second lower IDC contacts 310 and the subscriber IDC contacts 314 are parts of the same electrical conductors 304.
  • FIG. 12 to 18 show the contacts and conductors only for clarity
  • figures 19 to 21 show a physical arrangement corresponding to figures 12 to 18, and figures 22 and 13 show the necessary connections on the rear face of the arrangement shown in figures 19 to 21.
  • FIG 12 there is shown a plan view of a 7-pin connection point 400.
  • a central pin 402 is connected to earth 404.
  • a subscriber pair of connectors 406, 408 located to one side of the central earth connector 402 are connected to a wire pair 410 leading to a subscriber's premises.
  • On the other side of the earth connector 402 are two pairs of connectors, a first pair 412, 414 which are connected to a wire pair 416 leading to a subsequent distribution point and a second pair 418, 420 arranged either side of the first pair 412, 414 and which are connected to a wire pair 422 leading to the exchange.
  • a configuration module contains a pair of conductors 424,426 arranged and formed as shown in figures 13 and 14. Each is generally U-shaped with a connection point at either free end 428, 430 of the U. One free end 428 is half the width of the other 430, achieved by a step 432 along the U-profile, on one side.
  • the other conductor 424 has a like step in a mirror image configuration.
  • the free ends of the conductors 424,426 are able to mate with the connectors 406,408, 412, 414, 418 and 420 by suitable IDC formations on the latter (not shown).
  • Figures 15 and 16 show how these conductive elements can be connected.
  • Figure 16 shows a first disposition.
  • the conductors 424, 426 of the configuration unit engage with those connectors of the base unit 400 which are in an appropriate location to meet.
  • the wider free ends 430 bridge the first and second pairs of connectors 412, 418 and 414, 420 respectively whilst the narrower free ends 428 miss the subscriber pair 406, 408 since the asymmetric step 432 results in the narrower free end 428 being offset.
  • the configuration module is rotated through 180°. This places the narrower free ends 428 in the vicinity of the first and second pairs of connectors 412, 418 and 414, 420 and the wider free ends 430 in the vicinity of the subscriber pair of connectors 406, 408.
  • connection is made with the subscriber pair, but the narrower free end 428 only makes connection with the second pair 418, 420 leading to the exchange.
  • the subscriber is connected to the exchange but the spare tail of wire pair leading to the further distribution point is disconnected giving a clean copper connection to the exchange.
  • Figures 17 and 18 show the arrangement of conductors in a protected configuration module.
  • a three pole protector 432 is located above the U-conductors 424, 426 such that its end caps 434, 436 contact the conductors.
  • a further conductor 438 is arranged beneath the protector 432 in contact with its central earth contact 440, and descends downwardly to make contact with the earth connector 402 of the base unit 400, when in place.
  • FIGS 19 to 22 show an example using the conductor arrangement principle shown in figures 12 to 18. To demonstrate alternative ways of employing this principle, a physically different layout is illustrated in which the principle and mode of operation is however identical. To aid understanding, like reference numerals but incremented by 100 are employed to denote corresponding parts. Thus, figures 19 to 21 show the base unit 500 including a recess 540 in which are located the subscriber pair 506, 508, first pair 512, 514 and second pair 518, 520 of contacts. The configuration module (not shown) is able to fit into the recess and contains the U-conductors 524, 526 (shown).
  • the subscriber pair of contacts 506, 508 lead to a pair of IDC contacts 542, 544 to which a wire pair leading to the subscriber's premises may be attached.
  • the IDC contacts 542, 544 may be supported appropriately in a suitable structure and provided with wire carrying structures to permit a wire to be inserted and removed as necessary.
  • the precise structure of this is not germane to the present invention and will not be described in detail. Suitable structures are illustrated and described in our earlier patent publications GB-A-2,129,630, EP-A-0,683,925 and US-A-6,196,862.
  • the first pair of IDC contacts 512, 514 lead to IDC contacts 546, 548 which project from beneath the base unit 500. As shown in figure 22 they are connected to the IDC blades 550, 552 of a first MINI ROCKERTM connector 554 via wires 556, 558, for receiving the wire pair leading to the further distribution point.
  • MINI ROCKERTM connectors are single pair push-fit connectors for making connection to wire pairs as required. They are also shown, in a different context, in our earlier application published as GB-A-2,293,699.
  • the second pair of IDC contacts 518, 520 also lead to IDC contacts 560, 562 which project from beneath the base unit 500. As shown in figure 23 these are connected to the IDC blades 564, 566 of a second MINI ROCKERTM connector 568 for receiving the wire pair from the exchange.
  • the base unit 500 is fitted in a distribution point and wire pairs to the exchange and a further distribution point fitted to the MINI ROCKERTM connectors.
  • the configuration unit is then inserted in a first disposition, connecting the first and second IDC connectors 512, 514 and 518,520, and linking the exchange pair to the further distribution point pair.
  • the configuration unit is removed and a subscriber pair connected to the blades 542, 544.
  • the configuration unit is then replaced in a reversed disposition, thereby connecting the second IDC connectors 518, 520 to the subscriber IDC connectors 506, 508, linking the subscriber pair to the exchange pair and disconnecting the further distribution point pair.
  • the configuration unit is removed, the subscriber pair removed, and the configuration unit replaced in its original orientation.
  • the original network architecture is then restored with no loss of flexibility.
  • Figure 23 shows an alternative wiring for the base unit 500.
  • the A legs 546, 560 of the first and second IDC contacts are connected to the first MINI ROCKERTM and the B legs 548, 562 of the first and second IDC contacts are connected to the second MINI ROCKERTM.
  • the engineer fits the two A legs from the exchange and further distribution point pairs to the first MINI ROCKERTM and the B legs to the second MINI ROCKERTM. In some circumstances that may be more convenient.
  • the subsequent operation of the device is identical.
  • This comprises a 5-pair base unit 600 which is modular in form allowing one or more further 5-pair base units 602 etc to be attached at an end, thereby forming a 10,15, 20 etc pair module as desired.
  • An end cap 604 is provided to close the attachment points at the end of the base unit 600.
  • a lid 605 is provided to seal the base unit against the environment when it has been installed.
  • a base with a different number of pairs could alternatively be provided, but five is a convenient number.
  • each base unit 600 five substantially identical points are provided.
  • Each point includes a formation 606 for receiving a consumer plug 608, adjacent a pair of sockets 610, 612 for the link pair and the exchange pair respectively.
  • the sockets 610, 612 each contain a pair of connectors which are terminated via IDC blades at the rear on assembly or during installation with separate wire pairs.
  • the pair to the exchange socket 612 leads back to the central exchange, possibly via other distribution points, and the pair to the link socket 610 leads onward to a further distribution point. If the unit 600 is installed at the last distribution point then the link socket 610 can be left unconnected.
  • a bridging link 614 fits into the sockets 610, 612 at the initial installation. This contains a pair of conductors which make contact with conductors in the link and exchange sockets via IDC connectors and thereby connect the exchange wire pair to the link wire pair as per figure 3.
  • the consumer plug 608 When a consumer is to be supplied with service, the consumer plug 608 is inserted. It is held in place by retention formations (not shown in fig 24). Until now the relevant formation 606 for accepting this has been left empty, allowing the service provider to minimise investment in the plant.
  • the consumer plug 608 comprises a consumer socket 616 akin to the link and exchange sockets 610, 612 and a MINIROCKERTM type connector 618 as described above. Conductors within the consumer plug 608 make the necessary links between conductors in the consumer socket and 616 and the MINIROCKERTM. A wire pair leading to the consumer premises is then connected to the MINIROCKERTM.
  • bridging link 614 is removed from the link and exchange sockets 610, 612 and re-inserted in a 180° rotated orientation into the exchange socket 612 and the newly provided consumer socket 616. Connection is therefore broken with subsequent distribution points and made with the consumer, as per figure 4.
  • a cap 620 is provided to close the link socket 610 and seal it against the environment.
  • Earth connections within the base unit 600 are provided by an earth bar 622 which runs the length of the combined units 600,602 etc.
  • an earth strip 624 is provided which connects to the earth bar via an IDC connect 626 and provides the necessary earth conductors 628 appropriately positioned for access in the link and exchange sockets 610, 612. This permits protection to be integrated into the bridging link 614 if desired.
  • other active devices could be incorporated into the bridging link 614 as envisaged in our earlier publication EP 0683925. Such active devices include line termination devices, remote identification devices, subscriber management devices, or any desired device.
  • Figure 25 shows the electrical conductors within the unit.
  • the consumer plug 608 is present and the bridging link 614 is seated in the link and exchange sockets 610, 612.
  • Either side of the earth bar 622 and earth strip 624 are two adjacent conductors 630, 632 for the exchange pair which have IDC blades 634, 636 at their lower extremities for connection to the wire pair and flat blades 638, 640 at their upper extremities for connection with the bridging link 614.
  • a similar pair of conductors 642, 644 are provided for the link socket 610 for connection with a wire pair leading to any further distribution point.
  • a pair of conductors 646,648 Each extends from over the link socket 610 to over the exchange socket 612 and includes a pair of downwardly extending IDC blades 650, 652 projecting into the respective sockets and contacting with the conductors therein.
  • a pair of contacts 654, 656 extend from the consumer socket 616 to a point beneath the MINIROCKERTM.
  • a pair of double-ended IDC blades 658, 660 lie within the MINIROCKERTM and connect at their lower end with the contacts 654, 656. Their upper IDC contact is then available for connection to a wire pair leading to a consumer.
  • the contacts 656, 648 therein will instead connect the exchange contacts 634, 636 and the consumer contacts 654, 656.
  • Fig 26 shows the unit with the bridging link 614 in the link and exchange sockets 610, 612, partially cut away. This will therefore correspond to figure 3, the system as originally installed.
  • the consumer plug 608 has not yet been fitted.
  • a latch 660 on the base unit 600 engages with a tang 662 on the bridging link 614 to retain it in place.
  • Fig 27 shows the unit with the consumer plug 608 present and the bridging link 614 in the exchange and consumer sockets 612, 616. It is retained by a further latch 664 which engages with the tang 662.
  • the cap 620 is fitted in the link socket 610 and is retained by its own tang 668 which engages with the first latch 662.
  • the retention formations 670 for retaining the consumer plug 608 are visible.
  • the multiple IDC blades of the bridging link 614 could be made multiple-use, ie able to withstand repeated insertions.
  • the bridging link could be an inexpensive disposable item intended to be replaced at each reconfiguration of the line.
  • the part will also be lightweight, enabling engineers to carry a stock of such items to replace each time one has to be removed.
  • the bridging link 614 includes an arrow device 672 (fig 27) which denotes the appropriate link.
  • An asymmetric keying arrangement prevents the bridging link 614 from being inserted into the link socket 610 or the consumer socket 616 if it is incorrectly aligned.
