IN THE MATTER OF an Australian Application corresponding to PCT Application PCT/EP2003/007675 I, Jacqueline Michelle HARDY BA (Hons), translator to RWS Group Ltd, of Europa House, Marsham Way, Gerrards Cross, Buckinghamshire, England, do solemnly and sincerely declare that I am conversant with the English and German languages and am a competent translator thereof, and that to the best of my knowledge and belief the following is a true and correct translation of the PCT Application filed under No. PCT/EP2003/007675. Date: 17 February 2005 J. M. HARDY For and on behalf of RWS Group Ltd WO 2004/010536 - I - PCT/EP2003/007675 CONNECTOR FOR PATCH CABLES This invention relates to an electrical connector, an electrical connector element and a deflector element which forms part of, or is for use with, an electrical connector. 5 US Patent 6159020 describes an electrical connector having a hinged portion which can be moved from one position, in which access may be gained to the electrical contacts of the connector, to another position in which it is easier to pull the connector and an attached flexible cable through a space occupied by numerous wires. When in the latter 10 position, the hinged portion has a sloping surface which deflects wires as the connector is pulled through the space in order to prevent the wires from becoming tangled owing to the connector. While this arrangement is reasonably effective in use, it is relatively complex to manufacture products with hinged portions. 15 One aspect of the invention provides a deflector element for use with an electrical connector which can be attached to an electrical cable, the deflector element having a deflector surface, and it being possible to attach said deflector element to the cable when used with said connector such that it can slide on the cable to a first position, which is adjacent to the connector, such that the deflector surface is angularly disposed with 20 respect to the direction of extent of the cable so as to converge towards the cable away from the connector in order to deflect the electrical cable around the connector when the connector is moved, by the lead being pulled, through interstices in the electrical cabling, and such that it can slide to a second position on the cable so as to be spaced apart from the connector. In the second position, the deflector element may allow access to electrical 25 contacts of the connector. The invention also provides an electrical connector having an above-described deflector element. 30 Electrical contacts of an electrical connector for making external connections to the connector may be borne by an insulating body of the connector. Internal connections between the electrical contacts and electrical conductors to the contacts may be made in any suitable way, such as crimping the conductors to the connectors. Particularly in those WO 2004/010536 - 2 - PCT/EP2003/007675 cases where the external contacts are inside the connector, but remote from the location at which the conductors extend into the connector, separate, internal, conductive elements may be provided in the connector in order to provide connections between the conductors and the contacts. It may be difficult to position these elements and the conductors in the 5 connector during manufacture, particularly in cases where the contacts are in a relatively inaccessible part of the connector interior. One aspect thus provides an electrical connector element having a plurality of insulation displacement contacts and a plurality of electrical contacts, the insulation displacement 10 contacts and the electrical contacts being interconnected by electrical conductors, it being possible for the connector element to be received in a socket structure of a connector body of an electrical connector such that the insulation displacement contacts displace the electrical insulation of insulated wires received by the connector body in order to establish an electrical connection between the electrical conductors of the wires and the 15 insulation displacement contacts. This connector element may simplify coupling of the electrical contacts to wires leading to the connector. The connector element may be formed by a laminar, insulating substrate which bears the insulation displacement contacts. 20 The connector element is particularly useful when manufacturing a connector in which the externally accessible contacts are positioned in a part of the connector which is remote from, and overall parallel to, a part of the incoming cable when receiving the connector. Thus, the invention provides an electrical connector having a first portion 25 which has a cable receiving portion, for receiving an end portion of an electrical cable, so that the cable extends away from the first portion, on a first side thereof, in a direction transverse to the first portion, insulated wires of the cable being received by the first portion, said first portion having, at a location which is spaced apart from the cable receiving portion, a mounting structure which receives a first end portion of a connector 30 element such that the insulation displacement contacts of the connector element receive and make electrical contact with said wires, said connector element having, at a second end portion which lies opposite said first end portion, electrical contacts for making electrical connections to electrical contact members of a mating connector device, said WO 2004/010536 - 3 - PCT/EP2003/007675 connector element extending away from said first portion of the connector, on said first side thereof, so as to be overall parallel to said transverse direction. In one form, the connector is designed for mating assembly with a connector device in 5 the form of a connector module having openings for receiving said electrical contacts; said electrical connector, when assembled with the connector module, being arranged with said side of the first portion, which is adjacent to and extends transversely over part of the module, adjacent to said openings, and with the connector element extending therefrom into the module such that said electrical contacts of the connector engage with 10 the contact members of the module, and with said cable receiving portion being positioned for receiving the cable such that it extends away from the first portion which is adjacent to one side of the module. The invention also provides an electrical connector and a cable, the connector having a 15 first portion which has a cable receiving portion, which receives an end portion of the electrical cable, so that the cable extends away from the first portion, on a first side thereof, in a direction transverse to the first portion, insulated wires of the cable being received by the first portion, said first portion having, at a location which is spaced apart from the cable receiving portion, a mounting structure which receives an end portion of a 20 connector element such that the insulation displacement contacts of the connector element receive and make electrical contact with said wires, said connector element having, at an end portion which lies opposite said first end portion, electrical contacts for making electrical connections to electrical contact members of a mating connector device, said connector element extending away from said first portion of the connector, 25 on said first side thereof, so as to be overall parallel to said transverse direction. The invention also provides an insulation displacement contact having a structure, which defines a slot formed between two spaced-apart, opposing portions of the structure, in order to receive an insulated wire, by means of a lateral movement of the wire, so that the 30 wire is gripped between the opposing portions, and the insulation of the wire is displaced by means of the engagement with at least one of the opposing portions such that an electrical connection is established between an inner conductor of the insulated wire and said at least one opposing portion, the opposing portions being formed from an insulating material, a conductive edge portion being disposed on the insulating material at said at WO 2004/010536 - 4 - PCT/EP2003/007675 least one opposing portion at a location thereof in order to make said electrical connection. Preferably, said conductive edge portion is disposed on the insulating material at said at 5 least one opposing portion at an edge surface thereof which defines one side of the slot. Preferably, the insulation displacement contact is designed to displace the wire insulation by engaging with both of the opposing portions, a conductive edge portion being disposed on the insulating material at the other of said opposing portions in order to 10 establish an electrical connection between said inner conductor and the other said opposing portion. Preferably, the conductive edge portion is disposed on said at least one opposing portion at said at least one opposing portion at an edge surface thereof which defines one side of 15 the slot. Preferably, the conductive edge portions on the insulating material at each said opposing portion are disposed at edge surfaces of the opposing portions, which surfaces define respective sides of the slot. 20 Preferably, the structure is formed from a laminar, insulating substrate to which one or each said conductive edge portion is applied. The insulation displacement contact may be in the form of a printed circuit board, 25 conductor tracks being formed on the printed circuit board and being electrically coupled to one or each said conductive edge portion. The invention also provides an electrical connector made from a hollow body and a portion for receiving a connector element having insulation displacement contacts at one 30 end which are electrically connected to contacts on fingers at the other end, the fingers extending from openings in the hollow body, the hollow body being in two parts, one having said openings and an entry passageway for an electrical cable having insulated WO 2004/010536 - 5 - PCT/EP2003/007675 wires, and the other having a socket structure for receiving said one end of said connector element and said wires, the method including the steps of: (a) passing said wires through said entry passageway and arranging them such that they are received in said socket structure, 5 (b) assembling said connector element such that said one end is received and retained in said socket structure such that the insulation of the wires is displaced by said insulation displacement contacts in order to establish an electrical connection to the conductors of the wires and thus to the finger contacts, (c) assembling the parts of the body such that the connector element is 10 retained in said body, with said fingers extending externally thereof, and said finger contacts being positioned externally. The invention further provides an electrical connector having a hollow body which receives a connector element having insulation displacement contacts at one end which 15 are electrically connected to contacts on fingers at the other end, the fingers extending from openings in the hollow body, the body being in two parts, one having said openings and an entry passageway for an electrical cable having insulated wires, and the other having a socket structure, said wires passing through said entry passageway and being received in said socket structure, said connector element at said one end being received 20 and retained in said socket structure such that the insulation of the wires is displaced by said insulation displacement contacts in order to establish an electrical connection to the conductors of the wires and to the finger contacts, the connector element being retained in said body, with said fingers extending externally thereof such that said finger contacts are positioned externally. 25 The invention is described below, by way of example, with reference to the following, accompanying drawings, in which: figure I is a perspective view of the top of an electrical connector which is designed in 30 accordance with the present invention, the deflector element of the connector being shown in a position for use of the connector when making an electrical connection to a mating component; WO 2004/010536 - 6 - PCT/EP2003/007675 figure 2 is a view from below of an upper casing part of the connector in figure 1, an internal connector element of the connector, and an attached cable, the connector element being shown disassembled from the upper casing part; 5 figure 3 is a view as in figure 2, but showing the connector element assembled on the upper casing part; figure 4 is a perspective view as in figure 1, but showing a deflector element of the connector in a position for use in which it makes it easier to pull the connector through 10 interstices in a cable wiring space; figure 5 is a perspective view of the connector in figure 1 from the opposite side with a modified deflector element, in condition for use; 15 figure 6 is a side view of the connector and of the deflector element in figure 5; figure 7 is a front view of the deflector element shown in figure 5; figure 8 is a rear view of the deflector element in figure 5; 20 figure 9 is a side view of the deflector element in figure 5; figure 10 is a cross section substantially along the line 10-10 in figure 9; 25 figure I1 is a front view of the deflector element integrated in the connector in figure 1; figure 12 is a cross section along the line 12-12 in figure 11; figure 13 is a cross section substantially along the line 13-13 in figure 6; 30 figure 14 is a partial view of an end portion of the connector in figures I I and 12, in the position as shown in figure 2, in the region in which it engages with internal wires, when viewed in the rearward direction from a front main surface of the connector element as shown in figure 2; WO 2004/010536 - 7 - PCT/EP2003/007675 figure 15 is a partial cross section substantially along the line 15-15 in figure 14; figure 16is a perspective view of a connector which is formed in accordance with the 5 invention and is coupled to a connector module; figure 17is a transverse cross section through the module and the connector in figure 16 in the region in which the connector engages with the module; and 10 figure 18 is a vertical cross section through the connector in figure I and the deflector element interacting therewith. The connector 10 shown in figures I to 4 is designed to mate, in a manner described later, with the connector module 100, shown in figures 16 and 17. 15 The connector 10 has a hollow, electrically insulating connector body 12 and a separately formed deflector element 14. The deflector element 14 is retained such that it can slide on an electrical cable 16 which is connected to the connector body 12. 20 The connector body 12 is formed in two parts, an upper part 18 and a lower part 20. These are connected to one another by three snap fasteners 22, each comprising an aperture 24 on the body part 18, and a latching post 26, interacting therewith, on the body part 20. The posts 26 each have an inclined, leading guide surface 26a in order to deflect the posts by means of a guiding action against the edges of the apertures as the posts are 25 passed into the apertures, after which the guide surfaces pass through the apertures in order to allow the posts to return to a substantially undeflected position in which release of the two parts 18, 20 is prevented by the engagement of transverse locking surfaces 26b on the posts 26 at the edges of the apertures 24. 30 The connector body 12 overall defines a first bridging portion 30 having at one end a downwardly pointing portion 32, from which project contact portions 34 of the connector 10. As is best shown in figure 4, at the end of the first portion 30 opposite the portion 32, the body 12 has a cable receiving portion 36 (figure 4) which is formed on the lower body WO 2004/010536 - 8 - PCT/EP2003/007675 part 20 and which receives an end portion of the cable 16 such that the cable extends into the interior of the connector body. The cable receiving portion 36 is in the form of a downwardly projecting spigot having an overall cylindrical passageway 38 (figure 18). 5 The lower body part 20 defines the protruding portion 32, a lower part of the first portion 30 as well as the cable receiving portion 36 and the passageway 38. The body part 18 forms an upper closure for the connector body 12. At a location on the underside of the part 18 there is an internal, protruding spigot 40 10 which fits into the upper part of the passageway 38. The cable 16 passes into the connector 10 on the underside, through the spigot 40. Insulated wires 70 of the cable 16 extend out of the spigot via a side slot 42 in the spigot and into the interior of the body 12. 15 As is best shown in figure 3, the underside of the part 18 has, at its end lying opposite the spigot 40, a socket structure 44 which extends from side to side. This protrudes downwards from the underside of the part 18 and is formed as a rectangular wall 46 which defines therewithin an elongate, rectangular socket 48. In the assembled connector 10, the socket 48 extends internally across the connector 12 immediately above the 20 protruding portion 32 of the connector body part 20. As viewed from the side, in the case of the connector body 12 the cable 16 extends from a first side 49 adjacent to one end, and the portion 32 extends overall parallel on the same side, but adjacent the opposite end of the connector body 12. The cable receiving portion 25 36 also extends from the side 49 overall parallel to portion 32. One end of a connector element 50 of overall rectangular, planar form is accommodated within the socket 48 and is frictionally retained therein. The connector element 50 is shown in more detail in figures I1 and 12. It is formed as a printed circuit board having 30 an insulating substrate 52 having, overall, a rectangular configuration with conductive material arranged thereon so as to form the components as next described. Particularly, at a first end portion 55 of the substrate which is received in the socket 48, the substrate has insulation displacement contacts 54 formed thereon, which are arranged at the end edge WO 2004/010536 - 9 - PCT/EP2003/007675 of the substrate 52. At the opposite, second end portion 57, the substrate 52 is formed with an array of fingers 56 which extend such that they are spaced apart from, and parallel to, one another. 5 The IDCs 54 are formed by opposing portions 60 at the end of the substrate 52, adjacent pairs of which forming in each case individual IDCs. These portions 60 are in the form of protruding tongues. Each IDC has an outwardly open slot 58 which is defined between the pair of opposing portions 60 which form that IDC. This forms a gap between the portions 60. Edge surfaces of the slots 58 have electrically conductive edge portions 62. 10 These are formed in any suitable way, such as used when forming printed circuit boards using conventional techniques. By pressing an individual wire 70 of the cable 16 into an IDC slot 58, the insulation 72 surrounding the inner conductor 74 of the wire is cut by the edges of the IDC which are formed by the conductive edge portions 62 such that an electrical connection is made between the conductive edge portions 62 and the inner 15 conductor 74 (figures 14 and 15). To facilitate entry of the wire into the IDCs, the slots 58 have outwardly opening entry portions 58a which are wider at the edge of the substrate than at the inner ends of the slots. The socket structure 44 is designed to receive the wires 70 so that an electrical connection 20 is made between them and the IDCs 54 as the end of the connector element 50 at which the IDCs are located is positioned in the socket 48 of the socket structure 44. In particular, the wall 46 has, in portions thereof on opposite sides of the connector element 50, notches 76 which are arranged at an angle of 450 with respect to the longitudinal direction of the socket structure 44. With the connector element 50 removed from the 25 socket, the wires 70 are led from the cable 16, after it has been passed into the connector 10 via the cable receiving portion 36, so as to lie across the socket 48. Each wire 70 is thus received in two opposing notches 76 in the manner shown most particularly in figure 15. Pursuant to the angled alignment of the notches .76, the wires 70 thus lie at an angle with respect to the direction of extent of the socket 48. After this, the connector element 30 50 is placed in position and pressed downwards into the socket 48 so that the IDCs 54 make a connection with the wires 70 in the manner described above. The wires are then held in electrically conductive contact with the insulation displacement contacts 54 by virtue of the connector element 50 being frictionally retained within the socket 48.
WO 2004/010536 - 10 - PCT/EP2003/007675 The fingers 56 of the connector element 50 have bifurcated free ends, each forming two spaced-apart prongs 80. The prongs 80 have electrical contacts 82 therein, formed as conductive layers on opposite sides of the insulating substrate 52. Conductor tracks 78 on the printed circuit board, on each side, interconnect one of the contacts 82 with one of the 5 insulation displacement contacts 54. Of the contacts 82, in each case two are disposed on each prong 80, one on the side of the substrate 52 shown in figure 11, and one on the opposite side. On the substrate 52, however, only one of each pair on a single prong 80 is connected to a track 78, to be 10 precise in each case the contact on the side shown in figure 11. The conductive tracks 78 are formed partly on the side of the substrate 52 shown in figure I I and partly on the end side. Parts of the tracks on the opposite side are illustrated using dashed lines. Connections between parts of the tracks on both sides are made by annular, conductive portions 81 on the surfaces of through-holes through the substrate. The arrangement 15 results in the tracks 78 crossing over between adjacent pairs thereof. This may contribute to a reduction in the amount of crosstalk in signals passing on the tracks 78. When the connector 10 is assembled, the connector element 50 extends downwards within the connector body 12 from the socket structure 44 into the downwardly 20 protruding portion 32 of the body 12 so that the fingers 56 project downwards through openings 95 in a lower end wall 97 of the body portion 32 (figures 13 and 18). The portions, projecting in this manner, of the fingers 56 form the contact portions 34 of the connector 10. 25 As is best shown in figure 18, the connector element 50 is retained in position by the socket structure 44 by means of the engagement at the end portion 55 and by means of the engagement of inwardly directed steps 52a on the substrate 52 with projections 93 formed on the internal side walls of the connector body 12. This arrangement makes assembly of the connector 10 relatively simple. For example, the cable 16 may first be 30 passed through the deflector element 14, then through the passageway 38 in the cable receiving portion 36 of the body part 20 and into the spigot 40. End portions of wires 70 from the cable 16 may then be laid into the notches 76 on the socket structure 44, as shown in figure 3. Then, the connector element 50 may be assembled with the socket structure and the upper body part 18. After that, assembly may be completed by passing WO 2004/010536 - 11 - PCT/EP2003/007675 the fingers 56 through the openings 95 in the body part 20, and the body parts 18, 20 snapped together by being pressed towards each other so as to bring the snap fasteners 22 into engagement. The assembly may be performed with the upper wall portion 99 of the body part 18 (figure 13) facing downwards, as shown in figure 3. 5 The deflector element 14 has a body 84 which is made of, for example, plastic material. At one end, it has an entry portion 86 with a central passageway 94, by means of which the cable 16 extends through the deflector element 14. From the portion 86, the body 84 extends upwards, as viewed in figures I and 4, into an outwardly and upwardly opening 10 hollow portion 88. The portion 88 has a slightly conical form, but is flat on one side. Referring to figure 18, the passageway 94 is arranged so as to frictionally grip the cable 16 so that the deflector element 14 may be moved lengthwise on the cable, but still maintain a set position along the length of the cable owing to the frictional contact 15 therewith. In a position in which the deflector element 14 is moved on the cable 16 so as to be close to the connector body 12 and the deflector element 14 is appropriately rotated on the cable 16 (figures 1 and 18), the cable receiving portion 36 is received in an enlarged upper end of the passageway 94. In this state, the portion 88 of the deflector element 14 encompasses the underside of the connector body 12, and an overall planar 20 side surface 98 of the body 84 lies parallel to an inner, planar surface 28 of the body portion 32 such that it is spaced apart from it. The deflector element can, however, be moved away from this position downwards on the cable as seen in figure 1, and then to the side, to the right as viewed in figure 1, so that the cable 16 bends, so to pass below the lower end of the contact portions 34. It can then be moved upwards to the upper position 25 shown in figure 4 so that the contact portions 34 of the connector 10 are received in pockets 92 which are open at the top and are formed adjacent to, but inside, the side surface 98 of the deflector element 14. As a result, the portion 88 has a sloping, slightly conical deflector surface 88a around the contact portions 34. 30 With the element 14 positioned as shown in figure 4, the cable 16 may be used to pull the connector 10 through a space having numerous electrical wires without the connector being caught on the wires. As described, the portion 88 has a smooth, conical deflector surface 88a and, by means of this deflector surface 88a, as the cable and the connector are pulled through in this manner, either lines on both sides of the connector 10 are pushed 35 laterally outwards by the guiding action against the surface 88a of the deflector element WO 2004/010536 - 12 - PCT/EP2003/007675 14 or else, by a similar guiding action, the connector 10 itself and the deflector element 14 are in this manner moved to the side in order to enable the connector 10 and the deflector element 14 to pass easily. It will be appreciated that, because the connector 10 and the attached cable 16 on the other hand have a slightly U-shaped configuration, from 5 one end of which the cable extends, the connector may otherwise easily become tangled on surrounding wiring by it being caught between the portion 32 or the projecting contact portions 34 and the cable or the cable receiving portion 36. The deflector element 14 effectively bridges the portion 32 and the cable and the cable receiving portion 36. 10 Referring particularly to figures 16 and 17, the connector 10 is used to make connections to a module 100 by it being positioned such that the portion 30 and the projecting contact portions 34 extend to a central trough 104, which extends lengthwise, in the connector module, with the portion 30 extending laterally from the trough over the top of the module on one side, and with the cable 16 and the deflector element 14 being positioned 15 adjacent to an outer, upright surface 106 of the module. The trough 104 is defined between two opposing rows of upright posts 108 extending lengthwise along the upper part of the module. Between adjacent pairs of these posts are positioned insulation displacement contacts 112 (figure 17). These make it possible for 20 external connections to the module to be made by positioning wires (not shown) in them. The IDCs 112 are formed as parts of respective individual contact members 120 which have, at locations below the trough 104, upright spring contact portions 114. Opposing, associated IDCs 112 in each of these rows of said IDCs 112 have contact portions 114 in the immediate vicinity below the trough 104. The associated pairs of contact portions 114 25 may, for example, normally be engaged so as to interconnect associated contact members 120 across the rows or may normally be disconnected, that is to say not touching each other, so as to isolate the associated contact members 120. In any event, the trough 104 has, in a lower portion thereof, openings 122 into which the contact portions 34 project when the connector 10 is positioned on the module 100 in the manner shown in figures 30 16 and 17. The upper ends of the contact portions 114 are positioned such that they are displaced outwards as a contact portion 34 enters between them, and such that they interconnect with respective ones of the contacts 82 of the contact portions 34, across the module. Accordingly, when the connector 10 is assembled with the module 100 in this manner, electrical connections are made between the wires 70 of the cable 16, via the WO 2004/010536 - 13 - PCT/EP2003/007675 connector contact portions 34, and the contact members 120 of the module, via the contacts 82 and the contact portions 114. Figures 5 to 10 illustrate an alternative form of the deflector element 140 formed in 5 accordance with the invention. In these figures, like reference numerals denote like parts in figures 1 to 4 and I I to 18, and the following description is confined to differences between the deflector elements 14 and 140. In particular, the body 142 of the deflector element 140 has an extended, overall flat portion 144 on one side, the other side being overall partially conical with an outer surface similar to the surface 88a of the deflector 10 element 14 (figures 1 and 4). The portion 144 has, on its inside, pockets 92 for receiving the contact portions 34. The portion 144 is positioned immediately outside the contact portions 34 of the connector 10 when the deflector element is positioned for use for pulling through. In this configuration, an outer, overall flat surface 146 on the portion 144 lies substantially flush with an adjacent, overall planar surface 150 (figure 5) of the 15 connector body 12, and the fingers 56 of the connector element 50 are, as in the case of the deflector element 14, received in the pockets 92. Figure 10 illustrates the manner in which the fingers 56 of the connector 50 fit into the pockets 92. In this figure, the connector element 50 is shown by dashed lines in the pockets 92. The deflector element 140 can, however, be moved to the position shown in figure 6, in which the overall flat 20 portion 144 and the surface 146 lie overall parallel to, and spaced apart from, the portion 34 of the connector body 12. Embodiments of the invention can be used as connectors for patch cables, where the cable 16 is in the form of a patch cable. The patch cable may have connectors 10 at each 25 end, for example.
