The wire connection contacts are formed by two rows of insulation displacement contacts, which are arranged parallel to the side edges of the connector at the back.

Aus der DE 20 2005 001 178 U1 ist weiter eine RJ45-Buchse bekannt, bei der die zwei Reihen von Schneid-Klemm-Kontakten auf der Oberseite des Steckverbinders angeordnet sind, wobei die Reihen jeweils im rechten Winkel zu der Oberkante, Unterkante und den Seitenkanten steht.From the DE 20 2005 001 178 U1 Further, an RJ45 socket is known, in which the two rows of insulation displacement contacts are arranged on the top of the connector, wherein the rows each perpendicular to the top edge, bottom edge and the side edges.

Aufgrund des notwendigen Abstandes zwischen den beiden Reihen ist der Steckverbinder relativ breit, was beim Einbau der Steckverbinder in fest dimensionierte Einbauten wie beispielsweise 19"-Panele die Anzahl der einbaubaren Steckverbinder begrenzt.Due to the necessary distance between the two rows, the connector is relatively wide, which limits the number of installable connectors when installing the connector in fixed-sized fixtures such as 19 "panels.

Aus der US 6,358,093 ist ein elektrischer Steckverbinder mit HF-Kontakten und Aderanschlusskontakten bekannt, die auf gegenüberliegenden Seiten einer Leiterplatte angeordnet sind.From the US 6,358,093 is an electrical connector with RF contacts and wire connection contacts are known, which are arranged on opposite sides of a circuit board.

It is further disclosed as compensation measure that the RF contacts are partially crossed in pairs.

Aus der WO 2005/101579 A1 ist ein weiterer elektrischer Steckverbinder bekannt, bei dem HF-Kontakte und Aderanschlusskontakte über eine Leiterplatte verbunden sind, wobei auf der Leiterplatte kapazitive Kopplungen über Leiterbahnen zur Reduzierung des Übersprechens realisiert werden.From the WO 2005/101579 A1 Another electrical connector is known in which RF contacts and wire connection contacts are connected via a printed circuit board, wherein on the circuit board capacitive couplings are realized via interconnects to reduce crosstalk.

Aus der EP 0 899 828 A2 ist ein elektrischer Steckverbinder bekannt. Der Steckverbinder weist HF-Kontakte und Aderanschlusskontakte auf. Dabei werden jeweils ein HF-Kontakt und ein Aderanschlusskontakt durch ein einstückiges Kontaktelement gebildet. Die Verbindungsstege zwischen den Aderanschlusskontakten und den HF-Kontakten weisen dabei auch Kreuzungen auf. Die Aderanschlusskontakte sind dabei in zwei Reihen angeordnet.From the EP 0 899 828 A2 An electrical connector is known. The connector has HF contacts and wire connection contacts.

The connecting webs between the wire connection contacts and the RF contacts also have intersections. The wire connection contacts are arranged in two rows.

Aus der EP 0 982 815 A2 ist ein gattungsgemäßer elektrischer Steckverbinder bekannt, umfassend federnde HF-Kontakte und Aderanschlusskontakte, wobei die HF-Kontakte und die Aderanschlusskontakte miteinander elektrisch verbunden sind. Mindestens die HF-Kontakte sind in einem Gehäuse angeordnet, das eine Aufnahmeöffnung für einen Gegensteckverbinder aufweist. Die Aderanschlusskontakte sind in zwei parallelen Reihen angeordnet, wobei benachbarte Aderanschlusskontakte einer Reihe einen geringeren Abstand aufweisen als Aderanschlusskontakte verschiedener Reihen. Das Gehäuse weist eine Oberkante, eine Unterkante und zwei Seitenkanten auf, wobei die beiden Reihen von Aderanschlusskontakten parallel zur Oberkante des Gehäuses angeordnet sind. Weiter sind die HF-Kontakte und die Aderanschlusskontakte auf einer gemeinsamen Leiterplatte angeordnet und die Längsachsen der Aderanschlusskontakte parallel zur Oberfläche der Leiterplatte ausgebildet, wobei die Aderanschlusskontakte der einen Reihe weiter von der Leiterplatte angeordnet sind als die Aderanschlusskontakte der anderen Reihe.From the EP 0 982 815 A2 a generic electrical connector is known, comprising resilient RF contacts and wire connection contacts, wherein the RF contacts and the wire connection contacts are electrically connected to each other. At least the RF contacts are arranged in a housing having a receiving opening for a mating connector. The wire connection contacts are arranged in two parallel rows, with adjacent wire connection contacts of one row having a smaller spacing than wire connection contacts of different rows. The housing has an upper edge, a lower edge and two side edges, wherein the two rows of wire connection contacts are arranged parallel to the upper edge of the housing. Furthermore, the HF contacts and the wire connection contacts are arranged on a common printed circuit board and the longitudinal axes of the wire connection contacts are formed parallel to the surface of the printed circuit board, the wire connection contacts being arranged one row farther from the printed circuit board than the wire connection contacts of the other row.

Der Erfindung liegt daher das technische Problem zugrunde, einen Steckverbinder zu schaffen, der von den Breitenabmessungen schmal ausgebildet werden kann und dennoch ein geringes Übersprechen aufweist.The invention is therefore based on the technical problem of providing a connector which can be made narrow by the width dimensions and yet has a low crosstalk.

Die Lösung des technischen Problems ergibt sich durch den Gegenstand mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the technical problem results from the subject matter with the features of claim 1. Further advantageous embodiments of the invention will become apparent from the dependent claims.

Hierzu umfasst der elektrische Steckverbinder federnde HF-Kontakte und Aderanschlusskontakte, wobei die HF-Kontakte und die Aderanschlusskontakte miteinander elektrisch verbunden sind, mindestens die HF-Kontakte in einem Gehäuse angeordnet sind, das eine Aufnahmeöffnung für einen Gegensteckverbinder aufweist, und die Aderanschlusskontakte In zwei parallelen Reihen angeordnet sind, wobei benachbarte Aderanschlusskontakte einer Reihe einen geringeren Abstand aufweisen als Aderanschlusskontakte verschiedener Reihen, wobei das Gehäuse eine Oberkante, Unterkante und zwei Seitenkanten aufweist, wobei die beiden Reihen von Aderanschlusskontakten parallel zur Oberkante des Gehäuses angeordnet sind. Hierdurch wird erreicht, dass der Abstand zwischen den Reihen nicht verändert werden muss, was den Vorteil hat, dass die üblichen Anschaltwerkzeuge zum Beschalten der Aderanschlusskontakte weiter verwendet werden können. Zur Reduzierung der Breite müssen dann nur die Aderanschlusskontakte einer Reihe etwas zusammengeführt werden. Die erlaubt eine schmalere Ausbildung des Steckverbinders. Dabei wird vorzugsweise nur der Abstand zwischen verschiedenen Kontaktpaaren reduziert.For this purpose, the electrical connector comprises resilient RF contacts and wire connection contacts, wherein the RF contacts and the wire connection contacts are electrically connected to each other, at least the RF contacts are arranged in a housing having a receiving opening for a mating connector, and Core Connectors Arranged in two parallel rows with adjacent vias of one row spaced closer than vias of different rows, the package having a top edge, bottom edge, and two side edges, the two rows of vias being parallel to the top edge of the package. This ensures that the distance between the rows does not have to be changed, which has the advantage that the usual connection tools for connecting the wire connection contacts can continue to be used. To reduce the width, only the wire connection contacts of a row have to be brought together a bit. This allows a narrower design of the connector. In this case, preferably only the distance between different contact pairs is reduced.

Weiter sind die HF-Kontakte und die Aderanschlusskontakte auf einer gemeinsamen Leiterplatte angeordnet.Furthermore, the HF contacts and the wire connection contacts are arranged on a common printed circuit board.

Dabei sind die Längsachsen der Aderanschlusskontakte parallel zur Oberfläche der Leiterplatte ausgerichtet.The longitudinal axes of the wire connection contacts are aligned parallel to the surface of the printed circuit board.

Dabei sind die Aderanschlusskontakte der einen Reihe weiter von der Leiterplatte angeordnet als die Aderanschlusskontakte der anderen Reihe, wobei die Verbindungen der Aderanschlusskontakte der weiter entfernt liegenden Reihe zu der Leiterplatte paarweise gekreuzt sind.In this case, the wire connection contacts of one row further from the circuit board are arranged as the wire connection contacts of the other row, wherein the connections of the wire connection contacts of the farther row to the circuit board are crossed in pairs.

In einer bevorzugten Ausführungsform sind die Aderanschlusskontakte als Schneid-Klemm-Kontakte ausgebildet.In a preferred embodiment, the wire connection contacts are designed as insulation displacement contacts.

In einer weiteren bevorzugten Ausführungsform sind paarweise zueinander gehörige Aderanschlusskontakte einer Reihe zueinander parallel ausgerichtet, wohingegen benachbarte Aderanschlusskontakte unterschiedlicher Kontaktpaare in einer Reihe um 90° um die Längsachse der Aderanschlusskontakte gedreht zueinander angeordnet sind. Hierdurch wird die kapazitive Kopplung zwischen benachbarten Kontaktpaaren reduziert, die durch die Reduzierung des Abstandes erhöht wurde. vorzugsweise ist dabei der Abstand b bzw. b' zwischen Kontakten eines Kontaktpaares kleiner als der Abstand c bzw. c' zwischen Kontakten verschiedener Kontaktpaare.In a further preferred embodiment, paired core connection contacts of a row are aligned parallel to one another, whereas adjacent core connection contacts of different contact pairs are aligned in a row by 90 ° about the longitudinal axis the wire connection contacts are arranged rotated to each other. This reduces the capacitive coupling between adjacent contact pairs, which has been increased by the reduction of the distance. Preferably, the distance b or b 'between contacts of a contact pair is smaller than the distance c or c' between contacts of different contact pairs.

In einer weiteren bevorzugten Ausführungsform sind gegenüberliegende Aderanschlusskontakte unterschiedlicher Reihen um 90° um die Längsachse der Aderanschlusskontakte gedreht zueinander angeordnet. Hierdurch wird die kapazitive Kopplung zwischen den Kontakten verschiedener Reihen reduziert, was auch das Übersprechen reduziert.In a further preferred embodiment, opposing wire connection contacts of different rows are arranged rotated by 90 ° about the longitudinal axis of the wire connection contacts to one another. This reduces the capacitive coupling between the contacts of different rows, which also reduces crosstalk.

In einer weiteren bevorzugten Ausführungsform sind die Aderanschlusskontakte über SMD-ähnliche Kontakte mit der Leiterplatte verbunden.In a further preferred embodiment, the wire connection contacts are connected via SMD-like contacts to the circuit board.

In der Fig. 1 ist eine RJ45-Buchse nach dem Stand der Technik als elektrischer Steckverbinder 1 dargestellt. Der Steckverbinder 1 umfasst ein Gehäuse 2, das eine Aufnahmeöffnung 3 aufweist, in der HF-Kontakte 4 angeordnet sind, die durch einen Gegenstecker kontaktierbar sind. Das Gehäuse weist eine Oberkante 5, eine Unterkante 6 sowie zwei Seitenkanten 7 auf. Auf der Oberseite des Steckverbinders 1 sind zwei Reihen 8, 9 von Aderanschlusskontakten 10 angeordnet, die als Schneid-Klemm-Kontakte ausgebildet sind. Die beiden Reihen erstrecken sich dabei parallel zu einer Längskante 11 des Steckverbinders. Die beiden Reihen 8, 9 haben dabei einen vordefinierten Abstand, der es erlaubt, Adern 12 mit einem Anschaltwerkzeug in die Aderanschlusskontakte 10 zu drücken.In the Fig. 1 For example, an RJ45 socket according to the prior art is shown as an electrical connector 1. The connector 1 comprises a housing 2, which has a receiving opening 3, in which RF contacts 4 are arranged, which can be contacted by a mating connector. The housing has an upper edge 5, a lower edge 6 and two side edges 7. On the upper side of the connector 1, two rows 8, 9 of wire connection contacts 10 are arranged, which are formed as insulation displacement contacts. The two rows extend parallel to a longitudinal edge 11 of the connector. The two rows 8, 9 have a predefined distance, which makes it possible to press wires 12 with a connection tool in the wire connection contacts 10.

In der Fig. 2 ist eine alternative Bauform nach dem Stand der Technik dargestellt. Dabei sind die beiden Reihen 8, 9 nicht auf der Oberseite des Steckverbinders angeordnet, sondern an der Rückseite. Die beiden Reihen 8, 9 sind dabei parallel zu den Seitenkanten und im rechten Winkel zur Oberkante 5 angeordnet. Dabei sei angemerkt, dass die in Fig. 1 eingezeichnete Oberkante 5, Unterkante 6 und Seitenkanten 7 nicht mit den Kanten gemäß der Darstellung in Fig. 2 übereinstimmen, da dies zwei unterschiedliche Bauformen sind und die sichtbaren Kanten von Vorder- und Rückseite sich unterscheiden. Dies ist aber unkritisch, da es nur um die Parallelität zu den Kanten geht.In the Fig. 2 an alternative design according to the prior art is shown. The two rows 8, 9 are not arranged on the top of the connector, but on the back. The two rows 8, 9 are arranged parallel to the side edges and at right angles to the upper edge 5. It should be noted that the in Fig. 1 drawn upper edge 5, lower edge 6 and side edges 7 not with the edges as shown in FIG Fig. 2 Since these are two different designs and the visible edges of front and back are different. But this is not critical, since it is only about the parallelism to the edges.

Der Abstand a zwischen den Reihen 8 und 9 ist dabei derart dimensioniert, dass die Aderanschlusskontakte 10 durch ein Anschaltwerkzeug beschaltet werden können. Des Weiteren ist zu erkennen, dass alle vier Aderanschlusskontakte 10 einer Reihe 8, 9 zueinander parallel ausgerichtet sind, wobei die als Schneid-Klemm-Kontakte ausgebildeten Aderanschlusskontakte 10 in einen Winkel von 45° zu den Rippen 13 angestellt sind. Jede Reihe 8, 9 umfasst vier Aderanschlusskontakte 10, die jeweils paarweise zugeordnet sind, wobei die Aderanschlusskontakte 10 eines zugehörigen Paares durch eine Rippe 13 voneinander getrennt sind, wobei benachbarte Aderanschlusskontakte 10 verschiedener Paare durch einen breiten Steg 14 voneinander beabstandet sind. Wie man sieht, ist dabei die Breite c des Steges 14 größer als die Breite b der Rippe 13. Durch den großen Abstand zwischen den Aderanschlusskontakten 10 verschiedener Kontaktpaare wird dabei das Übersprechen reduziert.The distance a between the rows 8 and 9 is dimensioned such that the wire connection contacts 10 can be connected by a Anschaltwerkzeug. Furthermore, it can be seen that all four wire connection contacts 10 of a row 8, 9 are aligned parallel to one another, wherein the insulation terminal contacts designed as insulation displacement contacts 10 are set at an angle of 45 ° to the ribs 13. Each row 8, 9 comprises four wire connection contacts 10, which are each assigned in pairs, wherein the wire connection contacts 10 of an associated pair are separated by a rib 13, wherein adjacent wire connection contacts 10 of different pairs are spaced from each other by a wide web 14. As can be seen, while the width c of the web 14 is greater than the width b of the rib 13. Due to the large distance between the wire connection contacts 10 different contact pairs while the crosstalk is reduced.

In der Fig. 3 ist nun der erfindungsgemäße Steckverbinder 1 in einer Rückansicht dargestellt. Dabei sind nun die Reihen 8, 9 parallel zur Oberkante 5 ausgerichtet, wobei die Breite b' der Rippen 13 und/oder die Breite c' des Steges 14 kleiner als die Breite b bzw. c gemäß Fig. 2 gewählt werden kann. Dabei bildet der Steg 14 auch gleichzeitig eine Rippe für die Schneid-Klemm-Kontakte. Die Verringerung der Breite b' und/oder c' kann unmittelbar dazu genutzt werden, den Steckverbinder 1 schmaler auszubilden. Der Abstand a' zwischen den Reihen 8 und 9 wird dabei mindestens so groß gewählt, wie der Abstand a gemäß Fig. 2, damit die Beschaltung mit einem Anlegewerkzeug möglich bleibt. Die zugehörigen Aderanschlusskontakte 10 eines Kontaktpaares einer Reihe 8, 9 sind dabei wieder parallel zueinander ausgerichtet. Im Unterschied zu Fig. 2 sind jetzt jedoch benachbarte Aderanschlusskontakte einer Reihe 8 oder 9, die nicht zum gleichen Kontaktpaar gehören, um 90° um die Längsachse der Aderanschlusskontakte 10 gedreht angeordnet. Damit wird die kapazitive Kopplung zwischen diesen Kontakten reduziert. Weiter erkennt man, dass gegenüberliegende Aderanschlusskontakte 10 von verschiedenen Reihen 8, 9 auch um 90° um die Längsachse der Aderanschlusskontakte 10 gedreht zueinander angeordnet sind. Dies reduziert die kapazitive Kopplung und damit das Übersprechen zwischen den Aderanschlusskontakten verschiedener Reihen 8, 9.In the Fig. 3 now the connector 1 according to the invention is shown in a rear view. The rows 8, 9 are now aligned parallel to the upper edge 5, wherein the width b 'of the ribs 13 and / or the width c' of the web 14 is smaller than the width b or c according to Fig. 2 can be chosen. The web 14 also simultaneously forms a rib for the insulation displacement contacts. The reduction of the width b 'and / or c' can be used directly to make the connector 1 narrower. The distance a 'between the rows 8 and 9 is chosen to be at least as large as the distance a according to Fig. 2 so that the wiring remains possible with a placement tool. The associated core connection contacts 10 of a contact pair of a row 8, 9 are again aligned parallel to each other. In contrast to Fig. 2 However, adjacent core connection contacts of a row 8 or 9, which do not belong to the same contact pair, are now arranged rotated by 90 ° about the longitudinal axis of the wire connection contacts 10. This reduces the capacitive coupling between these contacts. Further it can be seen that opposing wire connection contacts 10 of different rows 8, 9 are also arranged rotated by 90 ° about the longitudinal axis of the wire connection contacts 10 to each other. This reduces the capacitive coupling and thus the crosstalk between the wire connection contacts of different rows 8, 9.

In der Fig. 4a ist der Steckverbinder 1 gemäß Fig. 3 perspektivisch ohne Gehäuse dargestellt. Entsprechend ist der Steckverbinder 1 gemäß Fig. 2 perspektivisch ohne Gehäuse in Fig. 4b dargestellt. Dabei werden ähnliche Elemente mit gleichen Bezugsziffern versehen, wobei die Elemente gemäß dem Stand der Technik nach Fig. 4b zusätzlich mit einem gekennzeichnet werden. Der Steckverbinder 1 umfasst acht Schneid-Klemm-Kontakte K31-K38, die jeweils paarweise zusammengefasst werden. Dabei bilden K31, K32; K33, K36; K34, K35 und K37, K38 jeweils ein Kontaktpaar.In the Fig. 4a is the connector 1 according to Fig. 3 shown in perspective without housing. Accordingly, the connector 1 according to Fig. 2 Perspective without housing in Fig. 4b shown. In this case, similar elements are provided with the same reference numerals, wherein the elements according to the prior art Fig. 4b additionally be marked with a. The connector 1 comprises eight insulation displacement contacts K31-K38, which are combined in pairs. In this case, K31, K32; K33, K36; K34, K35 and K37, K38 each a pair of contacts.

Die Schneid-Klemm-Kontakte K31, K32, K37, K38 bilden dabei Reihe 8 (siehe Fig. 3) und die Schneid-Klemm-Kontakte K33-K36 die Reihe 9 (siehe Fig. 3). Die Schneid-Klemm-Kontakte K31-K38 sind über SMD-ähnliche Kontakte 39 mit der Leiterplatte 40 verbunden. Im vorderen Bereich der Leiterplatte 40 sind die HF-Kontakte K21-K28 angeordnet. Die HF-Kontakte K21-K28 sind ebenfalls über SMD-ähnliche Kontakte 41 mit der Leiterplatte 40 verbunden. Wie man besonders gut in Fig. 5 erkennen kann, sind die Schneid-Klemm-Kontakte K31, K32, K37, K38 weiter entfernt von der Leiterplatte 40 angeordnet und somit die Kontaktlänge zur Leiterplatte 40 größer. Zur Kompensation dieser größeren Kontaktlänge sind die Verbindungen der Schneid-Klemm-Kontakte K31, K32 bzw. K37, K38 zur Leiterplatte 40 gekreuzt. Weiter erkennt man, dass die Längsachsen L der Schneid-Klemm-Kontakte K31-K38 parallel zur Oberfläche der Leiterplatte 40 liegen. Des Weiteren sieht man deutlich, dass die Schneid-Klemm-Kontakte eines Kontaktpaares jeweils parallel zueinander ausgerichtet sind, wohingegen benachbarte Schneid-Klemm-Kontakte (z.B. K31 und K38) unterschiedlicher Paare einer Reihe um 90° um die Längsachse L gedreht zueinander angeordnet sind. Gleiches gilt für senkrecht gegenüberliegende Schneid-Klemm-Kontakte unterschiedlicher Reihen (z.B. K32 und K33). Die HF-Kontakte K21-K28 werden durch ein Kammelement 42 vorgespannt und geführt. Dabei sind die inneren HF-Kontakte K22-K27 abwechselnd jeweils zueinander gebogen. Die beiden äußeren HF-Kontakte K21, K28 hingegen sind mechanisch länger ausgebildet, wobei diese eine kurze, elektrisch wirksame Kontaktstelle aufweisen, wo der HF-Kontakt 21, 28 federnd gegen eine Kontaktstelle auf der Leiterplatte 40 aufliegt. Diese elektrische Kontaktstelle liegt unter dem Kammelement 42 und ist daher nicht sichtbar.The insulation displacement contacts K31, K32, K37, K38 form row 8 (see Fig. 3 ) and the insulation displacement contacts K33-K36 the row 9 (see Fig. 3 ). The insulation displacement contacts K31-K38 are connected to the circuit board 40 via SMD-like contacts 39. In the front region of the printed circuit board 40, the RF contacts K21-K28 are arranged. The RF contacts K21-K28 are also connected via SMD-like contacts 41 to the circuit board 40. How to be particularly good in Fig. 5 can recognize, the insulation displacement contacts K31, K32, K37, K38 are located further away from the circuit board 40 and thus the contact length to the circuit board 40 is greater. To compensate for this larger contact length, the connections of the insulation displacement contacts K31, K32 or K37, K38 to the circuit board 40 are crossed. Furthermore, it can be seen that the longitudinal axes L of the insulation displacement contacts K31-K38 are parallel to the surface of the circuit board 40. Furthermore, it can be seen clearly that the insulation displacement contacts of a contact pair are each aligned parallel to each other, whereas adjacent insulation displacement contacts (eg K31 and K38) of different pairs of a row by 90 ° are arranged rotated about the longitudinal axis L to each other. The same applies to vertically opposed insulation displacement contacts of different series (eg K32 and K33). The RF contacts K21-K28 are biased and guided by a comb member 42. The inner RF contacts K22-K27 are alternately bent to each other. The two outer RF contacts K21, K28, however, are formed mechanically longer, which have a short, electrically effective contact point where the RF contact 21, 28 rests resiliently against a contact point on the circuit board 40. This electrical contact point is below the comb element 42 and is therefore not visible.

Des Weiteren erkennt man unterhalb der Leiterplatte 40 ein federelastisches Element 43, das über ein Zwischenstück 44 die Leiterplatte 40 elastisch vorspannt. Über diese federelastische Hubbewegung der Leiterplatte 40 können Toleranzen des Gehäuses sowie des Gegensteckverbinders ausgeglichen werden, so dass die HF-Kontakte K21-K28 im Ergebnis kürzer ausgebildet werden können. Um nun Rückwirkungen einer Hubbewegung der Leiterplatte 40 auf die Verbindung an den SMD-ähnlichen Kontakten 39 zu verhindern, wird das Gehäuse vorzugsweise zweiteilig ausgebildet, wobei das Gehäuseteil, das die Schneid-Klemm-Kontakte K31-K38 aufnimmt, beweglich mit dem anderen Gehäuseteil verbunden ist, das die Aufnahmeöffnung für den Gegensteckverbinder definiert. Die Leiterplatte 40 ist dabei fest im Gehäuseteil der Schneid-Klemm-Kontakte K31-K38 gelagert.Furthermore, it can be seen below the circuit board 40, a resilient element 43 which biases the circuit board 40 via an intermediate piece 44 elastic. Tolerances of the housing and of the mating connector can be compensated for by means of this resilient stroke movement of the printed circuit board 40, so that the HF contacts K21-K28 can be formed shorter as a result. In order to prevent repercussions of a stroke movement of the printed circuit board 40 on the connection to the SMD-like contacts 39, the housing is preferably formed in two parts, wherein the housing part, which receives the insulation displacement contacts K31-K38, movably connected to the other housing part is that defines the receiving opening for the mating connector. The circuit board 40 is fixedly mounted in the housing part of the insulation displacement contacts K31-K38.

Im Gegensatz zur Ausführungsform gemäß Fig. 4a steht die Längsachse L' der Schneid-Klemm-Kontakte K31'-K38' senkrecht zur Oberfläche der Leiterplatte 40'. Des Weiteren sind die Schneid-Klemm-Kontakte K31'-K38' über Lötpins mit der Leiterplatte 40 verbunden, ebenso wie die HF-Kontakte K21'-K28', die jedoch nicht alle sichtbar sind. Da in der Ausführungsform gemäß Fig. 4b die Stirnfläche 45 parallel zur Oberkante 5 des Gehäuses liegt, erkennt man, dass die Reihe, die durch die Schneid-Klemm-Kontakte K31', K32', K37' und K38' bzw. die Reihe, die durch die Schneid-Klemm-Kontakte K33'-K36' gebildet wird, senkrecht zur Oberkante 5 und parallel zur Seitenkante bzw. -fläche 46 der Leiterplatte 40' steht. Im Gegensatz hierzu sind die Reihen in der Ausführungsform gemäß Fig. 4a parallel zur Oberkante 5 (siehe Fig. 3) ausgerichtet. Zur weiteren Klarstellung des BegrifFs Reihe ist in Fig. 5 eine virtuelle Linie 50 eingezeichnet, die der Orientierung der Reihe 8 aus Fig. 3 entspricht. Abschließend sei noch einmal klargestellt, dass die Schneid-Klemm-Kontakte K31-K38 mit den HF-Kontakten K21-K28 gleichen Indices am Ende (also z.B. K35 mit K25) miteinander elektrisch verbunden sind, vorzugsweise über Leiterbahnen auf der Leiterplatte 40.In contrast to the embodiment according to Fig. 4a the longitudinal axis L 'of the insulation displacement contacts K31'-K38' is perpendicular to the surface of the circuit board 40 '. Further, the insulation displacement contacts K31'-K38 'are connected to the circuit board 40 via solder pins, as are the RF contacts K21'-K28', which are not all visible, however. As in the embodiment according to Fig. 4b the end face 45 is parallel to the upper edge 5 of the housing, it can be seen that the series, through the insulation displacement contacts K31 ', K32', K37 'and K38' or the series, which is formed by the insulation displacement contacts K33'-K36 ', perpendicular to the upper edge 5 and parallel to the side edge or surface 46 of the circuit board 40' is , In contrast, the rows in the embodiment are according to FIG Fig. 4a parallel to the upper edge 5 (see Fig. 3 ). For further clarification of the term series is in Fig. 5 a virtual line 50, the orientation of the row 8 from Fig. 3 equivalent. Finally, it should be clarified once again that the insulation displacement contacts K31-K38 are electrically connected to one another at the end (eg K35 with K25) with the HF contacts K21-K28, preferably via conductor tracks on the printed circuit board 40.
