Abstract
Description
- The present invention relates generally to electrical connectors and in particular to high transmission speed communication connectors.
- It is well known to transmit data over twisted-pair cabling for communication signal transmissions. A particular application where this cabling finds wide-spread use is in building wiring. In order to provide the flexibility necessary to utilize various pieces of equipment, which may have different interface requirements, it is desirable to have a flexible interconnect to the building wiring, as opposed to attempting to hard wire the equipment into the building wiring or to provide dedicated plugs for one particular interface requirements.
- One particularly advantageous flexible interconnect system is set out in EP 274 487. In this system, the building wiring is terminated in an edge-card connector. The edge-card connector is then mounted in a wall box. An interface insert that includes a common printed circuit board (PCB) with a standardized edge-card interface corresponding to the edge-card connector is provided. This insert further includes a communications connector mounted thereupon that is set in a mounting bezel so that as the insert is plugged into the edge-card, the bezel is received in the box. Depending upon the interface required, an insert with a different connector is incorporated onto the PCB and by exchanging the inserts, access to the building wiring is provided for various equipment interfaces. This provides the flexibility necessary to accommodate the many different types of equipment that are used within buildings today.
- Since this particularly flexible interconnection system has been introduced, the signal transmission speeds of copper-based communication systems have risen dramatically. As the signal transmission speeds have increased, so has the susceptibility of the signals being carried by the system to degradation from such things as the electro-magnetic interference from other electrical devices or cabling within the building and even adjacent signal line cross-talk.
- In order to accommodate the new signal transmission speeds, improved twisted-pair cabling has been developed. This cabling is known as foil shielded twisted-pair, screened foil shielded twisted-pair and pair in metal foil twisted-pair. These various shielding or screening techniques are used in order to try to prevent any outside influences from effecting the signal being transmitted along the cable and/or a particular twisted-pair. It is not uncommon, over the life of the building, for the internal wiring to be upgraded.
- In addition, improvements have been made to other parts of the system. For example, in EP 525 703 proposals to improve on an insert are set out. In addition, there has been much study relating to improving basic data connectors, such as the common modular jack receptacle. An example of this improvement is set out in US 5,186,647. Finally, it has been known to utilize metallized plastic boxes from US 5,484 308 or metal boxes for housing the cable termination and the edge-card connector. It is further known to electrically close the box by metallizing at least one side of the plastic adapter that fits around the connector mounted upon the PCB so that the interface with the building wiring is generally protected from the outside.
- However, signal speeds have continued to increase and further improvement on the existing system has brought the requirement to provide an improved edge-card connector. This improved edge-card connector should retain the desirable flexibility of the existing system and work with the already improved components thereof. Additionally, it is desirable that the improved edge-card connector would have backward compatibility so that it could be installed within existing systems. These goals have been met by the present invention, which while particularly attractive in an edge-card form, may be useful with other interfaces and outside of building wiring systems.
- The present invention addresses the aforementioned objects by providing a high frequency connector with: a main housing having an open mounting side, a cable side and a partition at the cable side defining two compartments where each compartment is in communication with the mounting side and the cable side; a plurality of contacts, where a pair of contacts are positioned in the compartments such that the contacts are exposed for mating with a complementary electrical interface on the mating side and wires of a cable on the cable side; and a rear cover that is fittable to the main housing on the cable side in order to close the open cable side and cover the exposed contacts therein where the cover further includes a second partition configured to mechanically and electrically engage the partition of the main housing where the two partitions are conductive and act as a shield between the two compartments.
- It is advantageous that this connector can be configured as an edge-card connector.
- It is further advantageous that the main housing and the cover can be conductive or metallized plastic to provide complete shielding of the interconnections within the connector and in particular individually shield the compartments.
- It is yet further advantageous that the compartments can be provided with a wire exit having a metallized saddle where any foil or screening about a twisted wire pair would sit such that shielding continuity would exist between the cable and the screening at a given compartment.
- It is still further advantageous that the partitions are formed with tongues having chamfered surfaces thereupon that abut with one another along the chamfers to assure shielding continuity between the compartments.
- An exemplary embodiment of the present invention will be described below with reference to the following figures, wherein:
- Figure 1 is an exploded perspective view of a building interface system utilizing a connector according to present invention;

- With reference first to Figure 1, a building wiring system interface utilizing the present invention is shown generally at 2. This building wiring system consists of a
cable 4 havingmultiple signal conductors 6 in the form oftwisted wires 8 that are surrounded byindividual shielding 10, which could take on the form of a foil. Theconductors 6 are terminated by anelectrical connector 12 incorporating the present invention. Theelectrical connector 12 includes amain housing 14 having an edge-card receivingslot 16 and arear cover 18. Theconnector 12 further includes alatch 20 for retaining theconnector 12 in anaccess box 22. While theconnector 12 utilizes an integrally moldedlatch 20, for snapping theconnector 12 into thebox 22, other mounting techniques may be used, such as a screw or other fastener. Thebox 22 is a rectangular shell having aforward opening 24, arear end 26 and acable exit 28. The forward end includeslatches 30 for retaining aninsert 32 therein. Theinsert 32 includes a PCB 34 having arear end 36 formed as a card edge with multiple conductors 38 thereupon. Aconnector 40 is incorporated onto the PCB 34. In particular, thisconnector 40 is a modular jack receptacle and provides aninterface 42 for receiving a modular jack plug (not shown). Theinterface 42 is surrounded by abezel 44 that includeslatch arms 46 to engagelatches 30 inbox 22 when theinsert 32 is placed within thebox 22. - A
rear cover 48 is provided to close therear end 26 of thebox 22 once theconnector 12 is mounted therein. Therear cover 48 includes atab 50 that is received within theslot 28 ofbox 22 when thecover 48 is affixed thereto. Thetab 50, in cooperation with the edges of theslot 28, engages thecable 4 to provide strain relief and possibly grounding of any general shielding of thecable 4 to thebox 22. - With reference now to Figure 2, the
electrical connector 12 according to the present invention is shown mounted within thebox 22. Thebox 22 includes amounting wall 52 which is engaged by thelatch 20 for retaining theconnector 12 therein. If theconnector box 22 is conductive, either by having been formed from a conductive material or a metallized plastic, and theconnector 12 is also advantageously formed of conductive material, such as metallized plastic, by placing theconnector 12 within thebox 22, theconnector 12 will be electrically commoned thereto. This will have further advantageous effects. - With reference now to Figure 3, the
electrical connector 12 will now be described in greater detail. Theelectrical connector 12 incorporates amain housing 14. Themain housing 14 has amating side 54 which in this example includes the card receiving slot 16 (Figure 1). It is important to note that while the present invention can be advantageously used in a card-edge connector style, that the invention should not be limited. Themain housing 14 also includes anopen cable side 56 that is divided into a plurality ofcompartments 58 bypartitions 60. Advantageously, themain housing 14 will be formed from a conductive material or metallized plastic. - A plurality of
contact carrying modules 62 are constructed to be received withincompartments 58. Thecontact carrying modules 62 include opposinglatches 64 so that they can be snapped in place within themain housing 14. Thecontact carrying module 62 is advantageously formed of insulative material although selective metallization could be used if desired. Eachcontact carrying module 62 includes twocontacts 66 that are best seen and described in Figures 4 and 5. Thesecontacts 66 include a mating end and awire termination end 70. - The
connector 12 further includes arear cover 18 that is fittable to themain housing 14 by a pair oflatch arms 72 designed to engage correspondingcatches 74 upon themain housing 14. Thecover 18 further includes multipleU-shaped cable tabs 76. It is also envisioned thattabs 76 may be omitted. Therear cover 18 will also be manufactured from a conductive material or advantageously a metallized plastic. - With reference now to Figures 4 and 5, the
contact 66 will be described in greater detail. Thecontact 66 includes amating end 68 that, in this embodiment, is a resilient tongue for engaging the conductive pads 38 of thecard edge 36. Various configurations of thismating end 68 may be realized depending on the interface desired. Thecontact 66 further includes acable termination end 70 that is formed as an insulation displacement contact (IDC). The IDC includes awire receiving slot 78 for receiving an insulated wire and making connection thereto, as is well known in the industry. Thewire termination end 70 could take on various other configurations, such as a crimp connection or a solder termination. Abody section 80 is located between themating end 68 and thewire termination end 70. Thebody portion 80 includes aretention lance 82 for incorporating thecontact 66 into thecontact carrying module 62. Various materials may be used for thecontact 66 as desired and it may be advantageous to include a preciousmetal contact patch 84 for engaging the conductive pads 38 of thecard edge 36. - With reference now to Figure 6, a
body 84 that substantially makes up thecontact carrying module 66 will be described in detail. Thebody 84 carries the twolatches 64 extending from afront surface 86 thereof. Thelatches 64 retain acontact carrying module 62 within themain housing 14 in a manner best seen in Figure 10. Thebody 84 includes arear IDC portion 88 having a pair ofcontact passageways 90 that extend through thebody 84 and open at thefront surface 86 so that acontact 66 may be disposed therein (best seen in Figure 10). Awire receiving slot 92 extends across theIDC termination portion 88 and the associatedcontact passageways 90 and is constructed for receiving theindividual wires 8 of the twisted-pair conductors 6 therein. Additionally, on either side of thecontact carrying passageway 90 areguide slots 94 that extend into themodule 84 basically parallel to thecontact receiving passageways 90. These guideslots 94, along withlarge chamfers 96 on both sides of thewire receiving slots 92, are useful for stabilizing a wire termination tool (not shown) that would be used to stuff the insulated wires into theIDC contact slot 70 of thecontact 66 in a manner well known in industry. - With reference now to Figure 7, the
main housing 14 will be described in greater detail. Theopen cable side 56 of themain housing 14 is shell-like and defined by alower wall 98, opposingside walls upper wall 103. This shell-likeopen cable side 56 is further divided into a row ofcompartments 58 bypartitions 60 that extend between thelower wall 98 and theupper wall 103. Advantageously, in this embodiment, thepartitions 60 are formed as tongues having a chamferedsurface 104 extending on a side thereof to anend 106 of thetongue 60. Theend 106 oftongue 60 is slightly recessed from theopen cable side 56 of theconnector 14. - Each
compartment 58 further includes a table 108 having an inverted, U-shaped, end 110 defining apassageway 112 thereunder and apassageway 114 thereover. Thepassageway 114 extends through thehousing 14 to themating side 54 while thepassageway 112 exposes alatch 116 for retaining thecontact carrying module 62. The table 108 is used to position thecontact module 62 within themain housing 14. - The
upper wall 103 is considerably thicker than thelower wall 98 or theside walls upper wall 103 carries at least a first portion of awire exit saddle 118. The first portion of thiswire exit saddle 118 includes a pair of scalloped saddle surfaces 120 that are separated by atab receiving trough 122 that extends into thewall 103 for receiving theU-shaped tabs 76 of thecover 18, as will be described below. As mentioned above, themain housing 14 would either be manufactured from a conductive material or molded from plastic and metallized such that themain housing 14 would provide shielding or anything received therein. - With reference now to Figure 8, the
end cover 18 that is constructed to close theopen cable side 56 of themain housing 14 will be described in greater detail. Theend cover 18 includeslatches 72 to engage thecatches 30 of the main housing in order to fix thecover 18 to themain housing 14. Thecover 18 includes abody portion 124 having arearward side 126 and aconnector side 128. Aninterior surface 130 of therearward side 126 faces theconnector side 128. Combined withside walls lower wall 136 andupper wall 140, a trough-like structure is formed. The trough-like structure is further divided into compartments 58A by second partitions 60A that correspond to thepartitions 60 of themain housing 14, as will be described below with reference to Figures 11 and 12. The second partition 60A also include chamfers 104A that extend along sides of the partition 60A to ends 142. It is important to note that at least a portion of the chamfer 104A of the partition 60A extends beyond theconnector surface 128 in order to provide theends 142 of thepartition 60 with some flexibility. In this particular embodiment, the second partition 60A itself extends asmall distance 144 beyond theconnector edge 128. Further, theend 142 of the partitions extends upwards to aledge 146 such that the second partitions 60A would be received between thelower wall 98 and theupper wall 103 of themain housing 14 when thecover 18 is fitted thereto. Advantageously, thecover 18 would be manufactured from a conductive material or a metallized plastic mold. Aportion 148 of the partition 60A extends above theledge 146 to be received withinslots 150 formed in theupper wall 103 of themain housing 14 that correspond to thepartition 60 therein. In addition, located along theupper wall 140 of thecover 18 are a plurality ofU-shaped tabs 76 constructed to be received within thetroughs 122 of themain housing 14. These legs of theU-shaped tabs 76 may take on various lengths as desired and provide some strain relief for the twisted-pair wire 6 and discontinuity in any pathway. As mentioned above, thesetabs 76 are optional. At the base of theU-shaped tab 76 is asecond saddle portion 152 that will be disposed opposite thefirst saddle portion 118 in themain housing 14. - With reference now to Figure 9, the
electrical connector 12 is shown in partially assembled form. Thecontact carrying modules 62, with thecontacts 66 therein, are shown received within themain housing 14. Thecover 18 is positioned to be mounted upon themain housing 14. As can be seen, the partition 60A will be received between adjacentcontact carrying modules 62 and theupper portions 148 of the partition 60A will be received in theslots 150. Additionally, if desired to improve the flexibility of thecover 18,reliefs 154 may be provided in therear surface 126. - With reference now to Figure 10, the
electrical connector 12 is shown in assembled form. Thecontact carrying module 62 with thecontact 66 is fitted to thehousing 14 by thelatch members 64 engagingcorresponding latches 116 formed in themain housing 14. Thecontact 66 extends through thecontact carrying passageway 90 such that themating end 68 is disposed in the cardedge receiving slot 16 on themating end 54 of themain housing 14. Thecontact 66 is retained therein by the lockinglance 82 that is received in arecess 156 of thebody 84 in order to further retain thecontact 66. A staking operation can be performed that utilizes therecess 158 above thecontact lance 82 prior to assembling of themodule 62 with themain housing 14 to further assure contact retention. At this point, the main housing has been assembled to the extent shown in Figure 9. - With the
cover 18 attached to themain housing 14 as shown in Figure 10, theopen cable side 56 of themain housing 14 has been closed. Awire exit 160 is defined by the twosaddle portions main housing 14 and cover 18 respectively for each of thecompartments 58. Thiswire exit 160 is configured to be slightly smaller than that of the wires exiting such that an interference will exist. This interference is advantageously taken advantage of by allowing the shielding 10 that surrounds thewires 8 to extend into the compartment and be terminated only slightly above therear IDC portion 88 of thecontact module 62 when thevarious conductors 6 are being terminated. Once thecover 18 is attached to themain housing 14, it is easily recognized that thesaddle portions main housing 14 and thecover 18 are manufactured from either conductive material or metallized plastic, the saddle surfaces 120, 152 are electrically commoned to the shielding 10. - Returning to Figure 1 and Figure 2, it can be seen that as a result of closing of the
rear cover 18 upon themain housing 14 with theconductors 6 extending therefrom, the shielding 10 of the individual conductors is slightly compressed in theregion 161 indicating engagement with thehousing 14 andcover 18. - With reference now to Figures 11 and 12, in addition to providing for the commoning of the conductive
main housing 14 andrear cover 18 to the shielding 10 of theindividual conductors 6 by way of thesaddle portions adjacent compartments 58 are completely isolated from one another. This is reliably achieved by thefirst partitions 60 of themain housing 14 and the second partition 60A of thecover 18 being provided withrespective chamfers 104, 104A and configured such that the respective ends 106, 142 also overlap and result in aslight interference 162 within thespace 164 betweenadjacent modules 84 contained within theirrespective compartments 58. As can be imagined, thisspace 164 and the associated partition walls are extremely thin and, hence, some flexibility of thepartitions 60, 60A is realized. Furthermore, it is this space requirement that prevents easily manufacturing these partitions as a single piece extending outward from either thecover 18 or thehousing 14 exclusively. As each of thepartitions 60, 60A are conductive, a shielding partition is formed betweenadjacent compartments 58. - Advantageously then, what is realized from the present invention is a structure that continues the shielding 10 provided to the twisted pair of
wires 8 to acompartment 58 within aconnector 12 such that a fully shielded twisted-pair interconnection is provided, thereby greatly reducing the effect of cross-talk fromadjacent signal conductors 6 and any spurious electro-magnetic fields.
