Definitions

  • 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.
  • Document DE69927451 T2 discloses a modular electrical connector with reduced crosstalk.
  • a printed circuit board which can be equipped with first conductors and second conductors.

  • 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. producing capacitive couplings. The targeted capacitive coupling to compensate for crosstalk thus takes place in the cable.
  • Document US7850492 discloses a communication connector with improved crosstalk compensation.

  • 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.
  • 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 1 1801 ,
  • 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; 2nd pair: contacts 3-6; 3rd pair: contacts 4-5; 4th pair: contacts 7-8.
  • such a connector has a coupling matrix which is suitable, for example, the contact 3 capacitive with the contacts 1, 5 and 7, ie with the other odd contacts, to be copied. to significantly reduce this crosstalk.
  • 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.
  • 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, also in the so-called “2K” (two-component) method, and in this way realize the necessary for the crosstalk compensation capacitive couplings in the contact carrier and thus relatively close to the contact areas of the contacts.
  • MID Manufacturing Interconnected Device
  • LDS laser Direct structuring
  • 2K two-component
  • the at least one compensation coating is advantageously 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.
  • 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 ⁇ , preferably less than or equal to 50 ⁇ and in particular less than or equal to 25 ⁇ and of course greater than 0 ⁇ , whereby, inter alia, by this small distance, the capacitive coupling is ensured to a sufficient extent.
  • This predetermined distance can be realized 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.
  • 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.
  • the contact carrier can be made in one piece.
  • the 2K method can be used as the MID method.
  • 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 the LDS-suitable substrate from which the contact carrier consists, before the thereby structured 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.
  • 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.
  • 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.
  • 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.
  • each contact carrier part can have eight channels corresponding to the preferred number of contacts. sen. 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.
  • 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.
  • 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.
  • 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.

  • 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.
  • the compensation coating may extend over the odd-numbered channels by passing their trace through the 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.
  • 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 importance Advantage is.
  • 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.
  • 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 lies between the respective contact and the associated contact. impaired coupling surface acts as a dielectric and spacers.

  • 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. This crossing makes it easier to already realize a rough crosstalk compensation.
  • 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.
  • their connection areas remain alternating, and thus match the usual connection profile of a given circuit board.

  • 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.
  • 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.
  • 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.
  • the holding areas of two contacts within the contact carrier can cross each other.
  • a coarse targeted capacitive coupling can be made in advance for compensation, but can not be set with sufficient accuracy.

Abstract

L'invention concerne un connecteur relativement simple à fabriquer, par exemple par la technologie MID, tout en assurant une bonne compensation de la diaphonie et donc un débit de transfert de données élevé. Son support de contacts se compose de deux parties de support de contacts assemblées entre lesquelles les contacts sont disposés. Chaque partie de support de contacts peut être dotée d'un revêtement de compensation électriquement conducteur séparé. Chacun de ces revêtements de compensation électriquement conducteurs possède une surface de connexion servant à établir une liaison électriquement conductrice avec un contact associé. En outre, chacun des revêtements de compensation électriquement conducteurs possède au moins une surface de couplage servant à réaliser un couplage capacitif ciblé avec un ou plusieurs autres contacts. Entre chaque surface de couplage et le contact associé est disposé un film isolant ou une partie d'un film isolant faisant fonction de diélectrique et de séparateur. Une sélection adéquate des contacts à coupler et de la capacité du couplage permet ainsi d'obtenir de manière simple une bonne compensation de la diaphonie indésirable.
