Definitions
- the present invention relates to an electrical connector.
- the present connection relates to an electrical connector having at least four elongate conductive elements each extending between a first contact at one end and a second contact at the other end, the first contacts being located in adjacent positions to a first amount thereof form, and the second contacts are arranged in adjacent positions to form a second set thereof, with first pieces of the conductive elements being different from the first
- Extend contacts from have a relatively narrow width and are arranged side by side over substantial parts of their lengths and extend substantially in the same direction, with opposite ones. Edges on adjacent ones of the first pieces are closely spaced with a substantially constant distance therebetween, and wherein second pieces of the conductive elements of at least two of the conductive elements extend alongside the respective second contacts substantially in a single plane and laterally with respect to said direction.
- the invention is characterized in that opposite edges on respective ones of the second pieces of the at least two conductive elements are spaced relatively wider than the substantially constant distance between adjacent edges of the first pieces. This can change the electrical properties of the connector.
- individual ones of the conductive elements can cross each other to provide cross-talk compensation, as described in U.S. Patents 5,186,647 and 5,310,363.
- the conductive elements may define a first, inner pair thereof and a second, outer pair thereof, wherein the conductive elements of the first pair lie side by side and intersect at locations between the second pieces thereof and the first contacts thereof, and the elements of the second pair adjacent each of the elements of the first pair and on either side of the first pair and do not cross each other, the at least two elements comprising the two conductive elements that form the individual ones of the first and second pairs and where adjacent the first and second pieces of it join, positioned on one side with respect to the direction .
- further two elements comprise the two conductive elements forming single, the first: and the second pair, which are positioned on the other side with respect to the direction in places next to those where the first and second pieces thereof connect, wherein the second pieces of the at least two elements extend angled to one side and the second pieces of the other two elements extend angled to the other side, such as at 45 "to the direction.
- each additional pair can cross.
- the characteristic impedance of the connector can be at least above an intended operating frequency applicable transmission power specifications, such as those for "Category 5" connectors under EIA568A, ISO 11801, AS / NZS 3080 and others equivalent standards are required to better match.
- the invention provides an RJ 45 type connector.
- the second contacts can, for example

- Figure 3 is a bottom view of one of the conductive elements shown in Figure 2;
- Figure 4 is a perspective view of a conductive member similar to that of Figure 3;
- Figure 5 is a diagram, the standard
- Figure 6 is a bottom view of another of the conductive elements shown in Figure 2.
- the connector 8 shown is a connector from
- Type RJ 45 has an insulating body 10 which houses eight electrically conductive elements (Figure 2). At first ends the elements are designed as respective spring contacts 30, whereby these extend into a socket 48 of the body 10 such that parts thereof are arranged for establishing an electrical connection with contact elements of a plug, not shown, when the plug is inserted into the socket.
- the elements 12, 14, 16, 18, 20, 22, 24, 26 each have forked insulation displacement contacts 28, which are designed such that the insulated wire conductors can be pressed into slots formed by the contacts, so that the insulation of the conductors is cut through the respective slots defining edges of the contacts and at the same time an electrical contact is made between the conductors and those edges.
- the contact elements 12, 14, 16, 18, 20, 22, 24, 26 each define intermediate parts which extend between the respective contacts 28, 30 and contain first pieces 40 which are connected to contacts 28 via second pieces 44.
- the elements 12, 14, 16, 18, 20, 22, 24, 26 are arranged such that when viewed transversely to their directions of extension, main parts thereof are in a linear arrangement.
- these main parts essentially comprise the entirety of each element, with the exception of only upstanding parts which define the contacts 28.
- the main parts extend more or less essentially in a common plane. It is possible to arrange the socket of a connector like that shown so that the pieces of those main parts which define the contacts 30 extend directly into a socket like the one shown in Figure 1 and for a better understanding of the nature of the elements 12, 14 , 16, 18, 20, 22, 24, 26, the elements are shown as being configured for this purpose.
- the socket 48 shown in Figure 1 is at right angles to the plane containing pieces 40 of the elements 12, 14, 16, 18, 20, 22, 24, 26, next to the contacts 28, and in this case the elements 12, 14, 16, 18, 20, 22, 24, 26 are bent approximately around the line AA in FIG. 2 at an angle of approximately 90 degrees in order to position them correctly in the socket.
- the contacts 30 are then contained in a plane which is correspondingly at approximately 90 degrees to the plane containing the pieces 40 and 44.
- the elements 12, 14, 16, 18, 20, 22, 24, 26 are connected in the usual use of the connector 8 so that they carry signals in four circuit paths 32, 34, 36, 38, as shown schematically in FIG.
- the signal path 32 thus contains the two innermost elements 18, 20, the circuit path 34 the two outermost elements 12, 14 on one side thereof, the circuit path 36 the two outermost elements 24, 26 on the other side thereof and the circuit path 38 the elements 16 and 22 between elements 14 and 18 and elements 20, 24, respectively.
- circuit path 38 This arrangement is common in the communications industry, but is known to cause problems because the resultant division of circuit path 38 so that it has signal carrying components (which are caused by pieces 40 at least of the elements 16 and 22), which are relatively far apart, but relatively close to signal-carrying components of the other three signal paths (as are formed in particular by at least the pieces 40 of the elements 14, 18, 20 and 24) are, at least at relatively high signal frequencies causes a substantial crosstalk between the circuit paths.
- crosstalk that arises in signals carried by circuit paths, such as signal paths 32, 34, 36, 38, contain significant adjacent spaced and parallel conductors as defined by elements 12, 14, 16, 18, 20, 22, 24, 26 can be reduced by crossing pairs of conductors at an appropriate point, such as in the middle along its length, or otherwise arranged to represent first and second pairs of portions of the circuit paths, before and after the crossover, introducing quenching signals when used by capacitive or inductive coupling.
- this is accomplished by crossing the pieces 40 of the inner members 18, 20 at an intersection 60 approximately midway along the lengths of these members and by crossing the pieces 40 of the members 12, 14 and the members 24, 26 towards ends of the pieces 40 of elements 12, 24 at intersections 62, 64 located at locations along the lengths of the pieces 40 of respective pairs of elements 12, 14; 24, 26 are positioned [lacuna] intersections 62, 64 are aligned transversely to the intersection 60 of the elements 18, 20.
- first and second pairs of sections of the signal paths 32, 34, 36, 38 are defined.
- a first pair of sections 34a, 38a are defined by respective adjacent sections of element 14 of circuit path 34 and element 16 of circuit path 38.
- a second pair of sections 34b, 38b of circuit paths 34, 38 are defined by respective adjacent sections of elements 12 and 16.
- a first pair of sections 38a, 32a, which are parts of the elements 16, 18, and a second pair of sections 38b, 32b, which are parts of the elements 16, 20, are defined between the circuit paths 38, 32.
- first pair of sections 32c, 38c that are part of elements 20, 22 and a second pair of sections 32d, 38d that are parts of elements 18, 22 are also defined between circuit paths 32, 38.
- a first pair of sections 38c, 36a are defined, which are parts of the elements 22, 24, and a second pair of sections 38d, 36b, which are parts of the elements 22, 26.
- the portions of the paths that comprise each pair are portions of the respective circuit paths that are in an adjacent spaced, generally parallel arrangement, but are arranged so that the relative phase of signals used between the portions of the first pair arises, which is opposite, which arises when used in sections of the second pair.
- This tool will generally result in the generation of antiphase crosstalk components in the circuit paths that typically cancel to reduce the level of crosstalk.
- This effect can be attributed to a 'capacitive coupling between the circuit paths, although there may also be a relevant inductive coupling.
- the contacts 30 and pieces 40 of the conductive elements 12, 14, 16, 18, 20, 22, 24, 26 are as shown “ “ “, side by side and relatively closely spaced.
- the pieces 44 on the contact elements 12, 16, 20 on one side of the connector are adjacent and parallel and those of the elements 18, 22, 26 on the other side are adjacent and parallel.
- the pieces 44 on the elements 12, 16 are adjacent and relatively closely spaced.
- the distance between parallel opposite edges 12a, 16b at these is indicated in FIG. 2 at "C”.
- the distance between the edges 26a, 22b of the pieces 44 on the elements 26 and 22 is also the distance "C”.
- the distance "C” is similar to the distance "D” between opposite edges of adjacent pairs of contacts 30.
- Pieces 44 of elements result in opposing edges 16a, 20a on elements 16, 20 and edges 22a, 26a on elements 22, 26 substantially a greater distance "E” than distance "D” over those of the lengths of pieces 44 are spaced therefrom. It has been found that the electrical characteristic of the connector 8 can be improved as a result.
- the contacts 30 had a width when viewed in FIG. 2 of approximately 0.4 mm, the distance "D" between them being approximately 0.56 mm.
- the pieces 44 of the elements 12, 16, 20 and 18, 22, 26 had a width of 1.9 mm, except where the recesses were present.
- the distance "C" between the pairs of edges 16a, 20a and edges 26a, 22a was 0.67 mm, the recess 42 on the pieces 44 of the elements 16, 22 having a width of approximately 0.5 mm and a length of Had 4.8 mm, the recess had a width of approximately 0.5 mm and a length of approximately 6 mm on the pieces 44 of the elements 20, 26.
- FIG. 3 shows the element 16 in the state shown in Figure 2.
- Figure 6 shows element 20.
- Figure 4 shows element 22 which is bent so that contact 30 is below 90E to piece 40, as explained above.
- the distance "E" should be present in general, over a substantial partial of time, such as 60% 'or more of the lengths of adjacent pieces 44th
- the distance “E” should preferably be substantially larger than the distance "D", for example at least 75% larger, such as in the substantial range of double to three times the distance "D". It is observed that in the arrangement described, the distance "D" between adjacent elements 12, 14, 16, 18, 20, 22, 24, 26 predominates over a substantial part of their lengths, such as at least 30% of these lengths.
- the described elements 12, 14, 16, 18, 20, 22, 24, 26 can be formed from strip material, for example by stamping and then by bending.
- blanks can be stamped out, pieces of which are bent out of the plane of the blanks to form contacts 28, and further bending is effected as required to configure the elements.
- the contacts 30 usually have curved parts Contact of the contact parts of a mating connector, and these can be shaped by appropriate bending processes.
- the contacts 30 are to be positioned in a plane at an angle to the plane containing the pieces 40 of the elements 12, 14, 16, 18, 20, 22, 24, 26, this can likewise be effected by bending.
- the blanks from which the elements 12, 14, 16, 18, 20, 22, 24, 26 are formed can be formed as a lead frame in which the blanks are substantially fully defined but are still connected so that they are can be handled together, but can be easily separated by subsequent cutting or punching.
- the connector described is an RJ45
- Connectors but it is to be understood that the invention can be applied to other types of connectors, particularly other connectors designed for use on balanced circuits.
- the purpose of improving the cross-talk characteristics of the connector for example to meet the requirements of the "Category 5" standards mentioned above, it can generally be used where mutual inductance is to be introduced into a connector, for example to improve the characteristic impedance of the connector so that it corresponds to a standard characteristic impedance of, for example, 100 ohms or 120 ohms.
