Description

The invention relates to a connector according to the preamble of independent claim 1.

Such connectors, such as RJ45 connector sockets, are used to transmit high frequency data signals.

State of the art

The publication DE69927451T2 discloses a modular electrical connector with reduced crosstalk. In this case, the use of a printed circuit board is disclosed, which can be equipped with first conductors and second conductors. Between the second conductors, eg insulation displacement terminals, which are provided for the cable connection, and the first conductors, for example plug contacts, the printed circuit board has conductor tracks on the outer layers. On an inner layer, the printed circuit board has capacitors in order to capacitively couple the printed conductors in order to influence the cross-talk behavior of the connector. The targeted capacitive coupling thus takes place in the field of printed conductors.

The publication WO9952182A1 discloses a modular electrical connector (male) and a corresponding cable connector assembly. Channels for cable reception are provided in the cable connection area. These channels may comprise electrically conductive material, eg a copper foil or an electrically conductive coating, in particular a metallised plastic, in order to correspond in the channels make capacitive couplings. The targeted capacitive coupling to compensate for crosstalk thus takes place in the cable.
The publication US7850492 discloses a communication connector with improved crosstalk compensation. In addition to the use of a rigid printed circuit board, the use of a flexible printed circuit board is disclosed, wherein both printed circuit boards have structures for compensating the crosstalk. The flexible printed circuit board is arranged on the otherwise free-standing contact ends of the spring-elastic contacts. It has tracks on both sides. On one side each conductor track arranged thereon contacts one of the contacts. However, there are fewer traces on this page than contacts, so some contacts are not electrically connected to any trace. By means of plated-through holes on further strip conductors, which are located on the other side of the flexible printed circuit board, capacitive couplings to other contacts are produced, wherein the flexible printed circuit board acts as a spacer and a dielectric. The contacts are grouped into symmetrically connected contact pairs 1-2, 3-6, 4-5 and 7-8. Then, for example, the particularly strong crosstalk between the contact pairs 3-6 and 4-5 is compensated by the contact 3 is capacitively coupled to the contact 5. By using a flexible circuit board directly to the contact ends a particularly high accuracy is achieved without restricting the functionality of the resilient contacts.

US Pat. No. 7,857,667 B1 A disadvantage in this prior art that it is very expensive in the manufacturing process of the connector, the required flexible printed circuit board at the ends of the otherwise free-standing contacts in the final position with the to position the necessary accuracy and finally fix it and optionally electrically conductively connect, eg to solder. On the other hand, has measurements and simulations show that the closer the targeted capacitive coupling is arranged to the free-standing ends of the contacts, the more precisely the crosstalk compensation can be set.

task

The object of the invention is therefore to provide a connector which can be produced on the one hand with the least possible effort, but at the same time also ensures good data transmission, in particular according to the Connector Categogy 6 _A (CAT6 _A ) according to the specification ISO / IEC 11801.

This object is achieved with a connector of the type mentioned by the features of the characterizing part of independent claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

The connector is a comparatively easy to manufacture connector, in particular an RJ45 socket, which preferably has eight contacts. These contacts are advantageously equipped with four symmetrical signal pairs. The following given pairwise summary of the contacts numbered consecutively in the contact sequence is defined as follows: 1. pair: contacts 1-2; 2. pair: contacts 3-6; 3. pair: contacts 4-5; 4. pair: contacts 7-8. In order to counteract the naturally resulting particularly harmful crosstalk between the contacts 2-3, 6-7, 3-4 and 5-6, such a connector has a coupling matrix which is suitable, for example, the contact 3 capacitive with the contacts 1, 5 and 7, so with the other odd contacts to couple so as to significantly reduce this crosstalk. As an alternative or in addition thereto, for reasons of symmetry following a comparable consideration, the contact 6 can also be capacitively coupled with the further even-numbered contacts, namely with the contacts 2, 4 and 8, in order to compensate for the said crosstalk.
On the one hand, the contact carrier of a connector according to the invention with comparatively little effort, for example in the so-called "MID" - (Molded Interconnected Device) technology, especially in the so-called "LDS" (laser Direct Structuring) method or, depending on the design, in the so-called "2K" (two-component) - be made method, and thus realize the need for crosstalk compensation capacitive couplings in the contact carrier and thus relatively close to the contact areas of the contacts. It is particularly advantageous that thereby eliminates the need for using a flexible circuit board with the appropriate connection and mounting effort. On the other hand, the capacitive coupling through the contact carrier, as measurements to simulations prove, at the same time a very good fine tuning of the capacitive crosstalk attenuation and thus a high data transmission rate. In particular, the transmission characteristics of the connector comply with the requirements of CAT6 _A.

In this case, the at least one compensation coating according to the invention is electrically conductively connected to one of the contacts and capacitively coupled to at least one other contact. The electrically conductive connection between the compensation coating and the one contact can be produced, for example, by pressing this contact directly against the compensation coating, for example, by the shape of the insulating body and, in particular, by joining two correspondingly shaped insulating body halves.

Furthermore, the compensation coating to the at least one other contact, with which it is capacitively coupled, have a predetermined distance which is less than 100 microns, preferably less than or equal to 50 microns and in particular less than or equal to 25 microns and of course greater than 0 microns , whereby, inter alia, by this small distance, the capacitive coupling is ensured to a sufficient extent. This predetermined distance is realized according to the invention by an electrically insulating layer, which consists, for example, in an insulating lacquer, but advantageously in an electrically insulating foil, the electrically insulating layer between the compensation coating and the at least one other contact, with which it is capacitively coupled , is arranged. Advantageously, this insulating layer, in particular the film, acts not only as a spacer between the compensation coating and the respective contact but also as a dielectric, which correspondingly enhances the capacitive coupling.
In an advantageous embodiment, the contact carrier can be made in one piece. Then, for example, the 2K method can be used as the MID method. But even in this one-piece design, for example, the LDS method can be used for coating, namely by the contact carrier has corresponding recesses through which a laser can make the corresponding activations of LDSgeeigneten substrate from which the contact carrier consists before the structured thereby electrically conductive coating is at least partially obscured by the inserted contacts. This one-piece design of the contact carrier has the advantage that a particularly precise guidance of the contacts is possible. This ultimately benefits the accuracy of decoupling.

In another advantageous embodiment, the contact carrier consists of two mateable contact carrier parts, for example a first and a second contact carrier part, and is thus made in two parts. This is advantageous in order to introduce the capacitive couplings and the contacts in the contact carrier with little effort and to simplify the assembly. Then, the contacts between the two contact carrier parts can be arranged and held in respectively designated channels of the contact carrier parts. The contact carrier parts can each have a connection surface and joined together with these connection surfaces and secured to each other, for example, glued or welded. In this case, a channel is provided in each connection surface of each contact carrier part for each contact. Such a channel may, for example, have two edges, each in the form of a collar, between which the associated contact can be inserted in a form-fitting manner. When assembling the contact carrier parts whose connecting surfaces are arranged together, wherein the associated channels are directly adjacent to each other and arranged the contacts in their respective channels each contact carrier part and in particular by the edges and / or adjacent webs form and locks are fixed therein. An advantage of the two-part embodiment of the contact carrier consists in the comparatively simple production, namely the simplification of the process of laser structuring of the first open connection surfaces of the individual contact carrier parts and the subsequent simplified assembly of the contact carrier with the contacts.

On each contact carrier part may further be provided a separate electrically conductive compensation coating, which extends over a plurality of channels of the respective contact carrier part. Each contact carrier part may have webs with the height d. Some of the channels can be arranged on such webs. In particular, each contact carrier part can have eight channels corresponding to the preferred number of contacts. Of these, for example, four channels can be located on bars. The webs may be distributed over the channels alternately, so that, for example, every second channel, that is, for example, each even-numbered or every odd-numbered channel, is arranged on a web. But it can also contacts each other between the assembled contact carrier parts, ie in the contact carrier, cross, ie that they change their channels within the contact carrier. This is taken into account in this design by a slightly more complex form of the contacts and the webs, the shape is chosen so that the contacts can make the channel change without touching each other.

The two contact carrier parts can be made substantially complementary to one another with respect to their webs, so that when the two contact carrier parts are assembled, one web of the one contact carrier part always engages in a web-free region of the other contact carrier part.

The contacts advantageously have a connection region, a holding region, a curvature region, a contact region and preferably an end region. But they can also be designed differently.

The holding regions of the contacts can be arranged between the two contact carrier parts. Thus, the contacts are held at their holding areas of the contact carrier. One reason for the good adjustability of the compensation is thus to be seen in the fact that the compensation by the compensation coating accordingly takes place at the holding areas and thus significantly closer to the contact areas of the contacts than would be the case if they were at the terminal areas, or even before would take place on connected cables or corresponding tracks. The holding regions of the various contacts may vary from channel to channel, for example alternately, in two different planes, namely a first plane and a second one Plane, lie, wherein the two planes have the distance d, ie in the first channel is the first contact and its holding area is in the first plane; in the second channel is the second contact and its holding area is in the second level.

The terminal areas of the contacts may be outside the contact carrier. As a result, these connection areas can be shaped so that they are located independently of the course of the holding areas and regardless of the configuration of the contact carrier in the desired plane, which is provided for their connection, for example on a printed circuit board.

In an advantageous embodiment, a region of the contiguous electrically conductive compensation coating can be regarded as a connection surface. This connection surface is intended to be electrically conductively connected to one of the contacts, preferably at its holding region. Furthermore, at least one further region of the compensation coating can be regarded as a coupling surface, and at least one further region can serve as a conductor track. The at least one conductor track can then connect the at least one coupling surface with the connection surface directly or indirectly, ie via one or more other coupling surfaces, in an electrically conductive manner. Each coupling surface is in each case provided for capacitively coupling with one of the further contacts. This is advantageous because this opens up the possibility of capacitively coupling the contact, which is electrically conductively connected to the pad, via the conductive compensation coating, namely the respective printed conductor, in an electrically conductive manner, for example with at least one further contact. By an advantageous selection and dimensioning of this capacitive coupling so the undesirable crosstalk can be counteracted so particularly effective because this capacitive coupling preferably takes place at the holding areas of the contacts.

Furthermore, each contact carrier part in at least one web, preferably in a plurality of webs, have a first recess, which connects in each case the two channels adjacent to the web. At least one contiguous electrically conductive compensation coating can be provided on each contact carrier half, whereby a part of the respective electrically conductive compensation coating in the form of the said conductor track can run through these first recesses. For example, if the lands are distributed among the even-numbered channels, then the compensation coating may extend over the odd-numbered channels by passing their trace through said first recesses in the lands of the even-numbered channels. The odd-numbered channels are provided, for example, for receiving the contacts 1, 3, 5 and 7. As a result, as already mentioned by way of example, the contact 3 in the second contact carrier part 22 can be capacitively coupled capacitively to the contacts 1, 5 and 7, whereby such an arrangement corresponds to the coupling matrix which is particularly advantageous for crosstalk compensation, and this arrangement is therefore also of particular advantage , Additionally or alternatively, the contact 6 in the first contact carrier part can be capacitively coupled to the contacts 2, 4 and 8. The latter can be realized in that the second contact carrier part is largely complementary to the first contact carrier part and thus coated analogously to the first contact carrier part, whereby a mirror-symmetrical decoupling matrix is formed in the contact carrier by the final joining of the two contact carrier parts with their connecting surfaces by the two associated compensation coatings in the contact carrier can.

Between each coupling surface and the associated contact, an electrically insulating layer, in particular a film formed from an electrically insulating material or a part of such a film can be arranged, which thus between the respective contact and the associated Coupling surface acts as a dielectric and spacers. For each contact carrier part, an additional one-piece film can be provided in each case. In order to enable the positive insertion of such a one-piece film, the two contact carrier parts between the channels and their adjacent channels may each have second recesses and the films may be performed for example E-shaped. Furthermore, a slight depression can also be provided, the depth of which preferably corresponds to the thickness of the film and whose shape preferably corresponds to the shape of the film, and into which the film can thus be inserted in a form-fitting manner.

In an advantageous embodiment, the connector has, as already mentioned, eight contacts. The contacts are electrically conductive and consist of a resilient material. As already mentioned, they have at least one connection region, a holding region, a curvature region and a contact region, and preferably an end region. In the bending area they are bent so that between the connection area and the contact area an angle exists that is smaller than 90 ° and greater than 0 ° and in particular between 30 ° and 60 °. The contacts can each be held with their holding area in the contact carrier, in particular between the two contact carrier parts. The curvature region and the connection region can be located outside the contact carrier.

The holding regions of the contacts can be arranged in the contact carrier in each case in one of the two said mutually parallel planes in the associated channels, wherein the two planes to each other have the distance d. This has the advantage that at least two contacts can cross each other without contact within the contact carrier, so that their positions in the order of the contact regions can be interchanged with respect to their positions in the order of their connection regions. By this crossing can be advantageously already realize a rough crosstalk compensation. In order to simultaneously ensure an alternating arrangement of the terminal regions with respect to the two planes, in the case of the two intersecting contacts, the terminal regions can again be offset by the distance d relative to the retaining regions. Then, the terminal region of such a contact lies in one of the planes and the holding region of the same contact lies in the respective other plane. However, their connection areas remain alternating, and thus match the usual connection profile of a given circuit board.

In an advantageous embodiment, the two mateable contact carrier parts each have an inner side. This has the advantage that the compensation coating can be applied, for example, in LDS (Laser Direct Structuring) technology, ie an MID (Molded Interconnect Device) technique. By inserting the contacts and joining the contact carrier parts then the capacitive coupling described above can be realized. The contacts can be arranged between the contact carrier parts in their designated channels. In order to avoid electrical contacting of the contacts with the coupling surface at their coupling regions, it is furthermore advantageous if at least one film is provided for each contact carrier part, which can advantageously be positively inserted into some channels and the compensation coating at the required locations, ie at least at the coupling surfaces, covering to avoid unwanted electrical contact with the corresponding contacts. For exact positioning of the film, as already mentioned, the corresponding depression can be provided into which the film can be inserted in a form-fitting manner. This film has a thickness which is less than or equal to 100 .mu.m, preferably less than or equal to 50 .mu.m, in particular less than or equal to 25 .mu.m. Their use on the coupling surfaces in addition to the electrical insulation also has the advantage as a dielectric and spacers, so that the capacitance of the respective capacitive coupling is adjustable inter alia by its material and its thickness.

Furthermore, the fully assembled connector, which additionally has an advantageously shielding housing can be mounted with the terminal portions of its contacts on a rigid circuit boards. In addition, other compensation structures on the connection side, e.g. in the form of printed conductors, be present on the rigid printed circuit board, are additionally selectively capacitively coupled via the terminal areas in order to initially roughly compensate for the unwanted crosstalk. For this purpose, as already mentioned, the holding areas of two contacts within the contact carrier can cross each other. Thus, a coarse targeted capacitive coupling can be made in advance for compensation, but can not be set with sufficient accuracy. The above-described capacitive coupling matrix through the compensation coating then additionally serves as a fine-tuning to ensure the accuracy of the capacitive couplings to reduce crosstalk and thus achieve a high data rate. Only then are the aspired high data rates possible.

The Fig. 1a, 1b, 1c and 1d All the contacts 1, 1 ', 1 ", 1'" are made in one piece, consist of an electrically conductive, resilient material and each have a connection area 11th , 11 ', 11 ", 11'", then a holding region 12, 12 ', 12 ", 12'", then a curvature region 13, 13 ', 13 ", 13'", then a contact region 14, 14th ', 14 ", 14'" and then an angled end portion 15, 15 ', 15 ", 15'". The connection region 11, 11 ', 11 ", 11'" delimits itself from the holding region 12, 12 ', 12 ", 12'" in that it is narrower.

The 1a shows a straight contact 1. Its holding area 12 represents a linear extension of the connection area 11. The holding area 12 and the connection area 11 extend in the X direction in a first plane E1, which is not shown in the drawing for reasons of clarity.

The Fig. 1b shows a staggered contact 1 '. This has in its basic design for straight contact 1 the essential difference that both the terminal portion 11 'and the holding portion 12' are arranged offset in the positive Z direction by the distance d, ie instead of in the first plane E1 in a second Level E2 lie, wherein the first plane E1 and the second plane E2 parallel to the XY plane and each other have the distance d. The second level E2 is not shown in the drawing for reasons of clarity.

The Figure 1C shows a bridging contact 1 ". This has in its basic design to the offset contact 1 'the difference that the holding portion 12" and the connection portion 11 "relative to the curvature region and the contact region 14" are additionally arranged offset in the positive Y direction and that the connection region 11 "is offset relative to the holding region 12" again by the distance d in the negative Z direction, so that the connection region 11 "lies again in the first plane E1.

The Fig.1d This differs from the straight contact 1 in that its holding area 12 "'and its terminal area 11"' are arranged offset in the negative Y direction together, and furthermore that the holding area 12 "'in the first Level E1 is guided, whereas the connection area 11 '"out in the positive Z-direction in the second plane E2 is guided .. The two levels E1 and E2 are not shown in this and in the other representations for reasons of clarity.

The Fig. 2a shows an arrangement consisting of four straight contacts 1 and four staggered contacts 1 'of the connector in a perspective view. For ease of understanding, the eight contacts C are arranged freely standing in their final position to each other. In this case, a straight contact 1 and an offset contact 1 'are always arranged in an alternating sequence. The contacts C are numbered consecutively in the order of their connection regions 11, 11 'with the reference symbols C1, C2, C3, C4, C5, C6, C7, C8.

The terminal areas 11 and holding areas 12 of the straight contacts 1 are arranged together in the first plane E1. The connection areas 11 'and holding areas 12' of the offset contacts 1 'are offset in the second plane E2, ie in the positive Z direction by the distance d to those of the straight contacts 1, arranged. All contacts C are aligned parallel to each other. Such an arrangement will be referred to hereinafter as "non-crossed" or "uncrossed" contacts because none of the associated contacts C intersect each other.

• C1' - aus einem geraden Kontakt 1,
• C2' - aus einem versetzten Kontakt 1',
• C3' - aus einem geraden Kontakt 1,
• C4' - aus einem gewinkelten Kontakt 1"',
• C5' - aus einem überbrückenden Kontakt 1",
• C6' - aus einem versetzten Kontakt 1',
• C7' - aus einem geraden Kontakt 1, und
• C8' - aus einem versetzten Kontakt,

wobei deren Anschlussbereiche 11, 11', 11", 11"' in der Reihenfolge dieser Aufzählung parallel zueinander und nebeneinander angeordnet sind. Eine solche Anordnung soll im Folgenden als "gekreuzt angeordnete Kontakte" bezeichnet werden, da sie mindestens zwei Kontakte C4', C5' besitzt, die einander kreuzen, indem sie in Form eines gewinkelten Kontaktes 1"' und eines überbrückenden Kontaktes 1" ausgeführt sind. Dadurch sind die Positionen ihrer Anschlussbereiche 11", 11"' gegenüber der Positionen der dazugehörigen Kontaktbereiche 14", 14"' gegeneinander vertauscht.The Fig. 2b shows an arrangement consisting of the following, with C1 ', C2', 'C3, C4', C5 ', C6', C7 ', C8' in the order of their terminal areas numbered contacts C '. It exists

• C1 '- from a straight contact 1,
• C2 '- from an offset contact 1',
• C3 '- from a straight contact 1,
• C4 '- from an angled contact 1 "',
• C5 '- from a bridging contact 1 ",
• C6 '- from an offset contact 1',
• C7 '- from a straight contact 1, and
• C8 '- from a staggered contact,

wherein their terminal portions 11, 11 ', 11 ", 11"' in the order of this list are arranged parallel to each other and side by side. Such an arrangement will hereinafter be referred to as "crossed contacts" since it has at least two contacts C4 ', C5' which intersect each other by being in the form of an angled contact 1 "'and a bridging contact 1". As a result, the positions of their connection areas 11 ", 11"'with respect to the positions of the associated contact areas 14 ", 14"' interchanged.

The Fig. 3a and 3b show a first contact carrier 2, consisting of a first contact carrier part 21 and a second contact carrier part 22, in a plan view of their respective connection surface V21, V22. Of the Contact carrier 2 serves to receive an arrangement of uncrossed, ie straight contacts 1 and offset contacts 1 'in an alternating sequence, as in Fig. 2a is shown. These two contact carrier parts 21, 22 are intended to be assembled after inserting the contacts C with their connecting surfaces V21, V22.

The first contact carrier part 21 has for this purpose first fastening means, namely in particular four fastening recesses 211, 211 ', 211 ", 211"', which are provided with second fastening means, in particular fastening pins 221, 221, '221 ", 221"' of the second contact carrier part 22 to cooperate. In particular, during assembly of the two contact carrier parts 21, 22, the first contact carrier part is oriented in such a way that the first attachment pin 221 of the first contact carrier part 21 is inserted into the first attachment recess 211 of the second contact carrier part 22, the second attachment pin 221 'of the first contact carrier part 21 into the second attachment recess 211 'Inserted the third contact pin 221' of the first contact carrier part 21 in the third mounting recess 211 'of the second contact carrier part 22 and the fourth mounting pin 221' 'of the first contact carrier part 21 in the fourth mounting recess 211' 'of the second contact carrier part 22 inserted becomes.

Furthermore, each of these two contact carrier parts 21, 22 eight parallel channels K, K 'on. The channels K of the first contact carrier part 21 are numbered from the connection side view with respect to the corresponding contact side from right to left with the reference numerals K21, K22, K23, K24, K25, K26, K27, K28. The corresponding channels K 'of the second contact carrier part 22 are from the connection side view with respect to the associated contact side accordingly from left to right with the reference numerals K21', K22 ', K23', K24 ', K25', K26 ', K27', K28 ' numbered. For the final assembly of these two contact carrier parts 21, 22, the first contact carrier part 21 is thus, as described above with reference to the fastening means, placed on the second contact carrier part 22 in such a way that the equal-numbered channels, ie the channels K21 and K21 'and the channels K22 and K22', etc., face each other come to rest and together form the channels of the first contact carrier 2 in order to fix the corresponding contacts C therein.

The even-numbered channels K22, K22 ', K24, K24', K26, K26 ', K28, K28' are each provided for receiving an offset contact 1 '. For this purpose, the even-numbered channels K22, K22 ', K24, K24', K26, K26 ', K28, K28' in relation to the odd-numbered channels K21, K21 ', K23, K23', K25, K25 ', K27, K27' in Z-direction offset by the distance d arranged. For this purpose, webs 225, 228 of the height d are arranged in the second contact carrier part 22 in the even-numbered channels K22 ', K24', K26 ', K28', wherein not all webs are each provided with a reference numeral. In this case, which is the web 228 in the channel K28 'running continuously, so is interrupted by any recess. In the channel K22 ', the web 225, as well as two further webs in the channels K24' and K26 ', interrupted by a first recess 226 and a second recess 227. These two recesses are exemplarily provided with reference numerals. Comparable recesses also appear in other webs, without being provided with a reference numeral. Similarly, the first contact carrier part 21 in the first channel K21 also has a continuous web 218 with two collars 212, 212 'and a web interrupted by two recesses 216, 217.

In the first contact carrier part 21 corresponding webs in the odd-numbered channels K21, K23, K25, K27 are arranged and are partially interrupted by recesses 316, 317, 326, 327.

When joining the two contact carrier parts 21, 22 is thus in each case a channel having a web K21, K22 ', K23, K24', K25, K26 ', K27, K28 'arranged in a channel which has no web, K21', K22, K23 ', K24, K25', K26, K27 ', K28. Thus, when joining each web of a contact carrier part 21, 22 in a web-free region of the other contact carrier part 22, 21 is arranged. Furthermore, each channel has at its two edges in each case a collar, so that the contacts 1, 1 'with their holding portions 12, 12' between these collar at least partially form-fitting manner can be inserted. For example, has the channel K28 'at the two edges of its web 228 each have a collar 222, 222' and the channel K21 has at the two edges of its web 228 each have a collar 212, 212 '. For reasons of clarity, the further collars of the second and third contact carrier are not provided with reference numerals.

Even those channels which have no webs, have at their edges such collars, but which are optionally interrupted by the first and second recesses 216, 217, 226, 227.

The Fig. 3c and 3d alternatively show a second contact carrier 3, consisting of a third contact carrier part 31 and a fourth contact carrier part 32 in a plan view of the respective connection surface V31, V32 of the two contact carrier parts 31, 32.
