Description

Die Erfindung betrifft ein Koaxial-Steckverbinderelement zur Verbindung mit einer Stiftleiste.The invention relates to a coaxial connector element for connection to a pin header.

Bei Geräten der Nachrichten- und Übertragungstechnik, z.B. bei modernen Geräten der Telekommunikationstechnik, werden in zunehmendem Maße HF-Signale über NF-Steckverbinder-Kontakte übertragen. In diesem Fall müssen die für die Übertragung von HF-Signalen verwendeten Koaxialkabel an NF-Stiftleisten angeschlossen werden können.In devices for communication and transmission technology, e.g. With modern devices in telecommunications technology, RF signals are increasingly being transmitted via NF connector contacts. In this case, the coaxial cables used for the transmission of RF signals must be able to be connected to NF pin headers.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Koaxial-Steckverbinderelement in einer zur Verbindung mit einer Stiftleiste geeigneten Weise auszubilden.The invention is therefore based on the object of designing a coaxial connector element in a manner suitable for connection to a pin header.

Diese Aufgabe wird gemäß der Erfindung durch folgende Merkmale gelöst:

  • a) das Steckverbinderelement ist am Außenumfang seines mit der Stiftleiste verbindbaren Endes zur Kontaktherstellung mit zwei einander diametral gegenüberliegenden oder mit vier an den Eckpunkten eines Quadrats liegenden Stiften der Stiftleiste in korrespondierender Weise mit zwei einander diametral gegenüberliegenden bzw. mit vier in gleichem Abstand voneinander angeordneten, nach außen vorstehenden, federnden Kontakt-Lamellen ausgebildet,
  • b) zur Kontaktierung mit einem weiteren Stift (Mittelstift), der zwischen den diametral gegenüberliegenden zwei Stiften bzw. mittig innerhalb der an den Eckpunkten eines Quadrats liegenden Stifte angeordnet ist, ist im Inneren des Steckverbinderelementes eine gegenüber den Kontakt-Lamellen fest positionierte Innenleiterbuchse vorgesehen.
This object is achieved according to the invention by the following features:
  • a) the connector element is on the outer periphery of its end which can be connected to the pin header for making contact with two diametrically opposite pins or with four pins of the pin header lying at the corner points of a square in a corresponding manner with two diametrically opposite pins or with four arranged at the same distance from one another, resilient contact blades projecting outwards,
  • b) for contacting with another pin (center pin), which is between the diametrically opposite two pins or in the middle within the corner points of one Arranged square pins, an inner conductor socket is provided in the interior of the connector element in relation to the contact lamellae.

Ein derartiges Koaxial-Steckverbinderelement ist entweder mit zwei oder mit vier Kontakt-Lamellen ausgebildet. Eine in manchen Fällen ausreichende Kontaktierung läßt sich bereits mit zwei Kontakt-Lamellen herstellen, vorzugsweise ist das Steckverbinderelement jedoch mit vier Kontakt-Lamellen ausgebildet.Such a coaxial connector element is designed either with two or with four contact blades. Sufficient contacting in some cases can already be achieved with two contact blades, but the connector element is preferably designed with four contact blades.

Das erfindungsgemäße Koaxial-Steckverbinderelement ist mit den äußeren Kontakt-Lamellen und der inneren Innenleiterbuchse in einer zum Anschluß eines Koaxialkabels an die Stifte einer Stiftleiste gut geeigneten Weise ausgebildet, wobei die Kontaktherstellung mit den Stiften ohne zusätzliche Maßnahmen einfach durch Aufstecken des Koaxial-Steckverbinderelementes auf die Stiftleiste in sicherer Weise erfolgt. Beim Aufstecken des Steckverbinderelementes z.B. auf ein 9er-Stiftfeld einer Stiftleiste werden entsprechend der Ausbildung und Anordnung mit Kontakt-Lamellen zwei oder vorzugsweise vier Stifte und ein Mittelstift kontaktiert. Bei Ausbildung eines Steckverbinderelementes mit vier Kontakt-Lamellen kann dann also mit einem 8-fach-Stecker ein Stiftfeld von 9 x 5 Stiften auf engstem Raum kontaktiert werden. Das erfindungsgemäße Steckverbinderelement bedarf trotz Ausbildung mit Kontakt-Lamellen an seinem Außenumfang praktisch keiner größeren Dimensionierung, so daß es besonders kompakt ausgebildet werden kann und für den Anschluß von Koaxialkabeln an NF-Stiftleisten mit einer Vielzahl von eng benachbarten Stiften besonders gut geeignet ist.The coaxial connector element according to the invention is formed with the outer contact lamellae and the inner inner conductor bushing in a manner which is well suited for connecting a coaxial cable to the pins of a pin strip, the contact with the pins being established without additional measures simply by plugging the coaxial connector element onto the Pin header is done in a safe manner. When plugging the connector element, for example on a 9-pin field of a pin header, two or preferably four pins and a center pin are contacted with contact lamellae in accordance with the design and arrangement. When designing a connector element with four contact lamellae, a pin array of 9 x 5 pins can then be contacted with an 8-way connector in a very confined space. The connector element according to the invention, in spite of its formation with contact lamellae, requires practically no larger dimensions on its outer circumference, so that it can be made particularly compact and is particularly well suited for connecting coaxial cables to NF pin headers with a large number of closely adjacent pins.

Zweckmäßigerweise sind die Kontakt-Lamellen von Federarmen einer verdrehgesichert auf dem Außenumfang des Steckverbinderelementes fixierten Hülse gebildet. In diesem Fall ist das Steckverbinderelement in besonders einfacher Weise mit Kontakt-Lamellen ausgebildet.The contact lamellae are expediently formed by spring arms of a sleeve secured against rotation on the outer circumference of the connector element. In this case, the connector element is designed in a particularly simple manner with contact lamellae.

Hinsichtlich der Kontaktsicherheit zwischen einem Koaxial-Steckverbinderelement und den Stiften einer Stiftleiste ist es vorteilhaft, wenn sich die federnden Kontakt-Lamellen vom Ende des Steckverbinderelementes weg in dessen Längsrichtung erstrecken und im unbelasteten Zustand schräg zu dessen Längsachse abstehen.With regard to the security of contact between a coaxial connector element and the pins of a pin header, it is advantageous if the resilient contact lamellae extend away from the end of the connector element in its longitudinal direction and project obliquely to its longitudinal axis in the unloaded state.

Bei einem erfindungsgemäßen Koaxial-Steckverbinderelement ist es besonders zweckmäßig, wenn an der der Stiftleiste zugewandten Seite der Kontakt-Lamellen ein Ring auf dem Steckverbinder fixiert, z.B. aufgepreßt ist, der mit einer der Anzahl der Kontakt-Lamellen entsprechenden Anzahl von nach außen offenen und zu den Kontakt-Lamellen fluchtenden Nuten versehen ist. Ein derartiger Ring dient mit seinen Nuten der Vorpositionierung des Steckverbinderelementes beim Steckvorgang, so daß die Kontakt-Lamellen sicher auf die Stifte der Stiftleiste Zugeführt werden und nicht in die Zwischenräume zwischen den Stiften geraten.In the case of a coaxial connector element according to the invention, it is particularly expedient if a ring is fixed on the connector on the side of the contact lamella facing the pin strip, e.g. is pressed on, which is provided with a number corresponding to the number of contact blades of outwardly open and aligned with the contact blades grooves. Such a ring is used with its grooves to pre-position the connector element during the plugging process, so that the contact lamellae are securely fed onto the pins of the pin header and do not get into the spaces between the pins.

Es ist auch vorteilhaft, wenn vor der Innenleiterbuchse ein Isolierteil mit einer Vorzentrierbohrung für den Mittelstift angeordnet ist, so daß auch ein sicherer Eingriff des Mittelstiftes in die Innenleiterbuchse gewährleistet ist.It is also advantageous if an insulating part with a pre-centering hole for the central pin is arranged in front of the inner conductor bushing, so that a secure engagement of the central pin in the inner conductor bushing is also ensured.

Zweckmäßigerweise ist das erfindungsgemäße Koaxial-Steckverbinderelement so aufgebaut, daß es eine Außenleiterhülse aus leitendem Material aufweist, an deren einem Ende außen die Kontakt-Lamellen vorgesehen und innen die Innenleiterbuchse angeordnet ist und an deren anderem Ende ein Koaxialkabel angeschlossen ist.The coaxial connector element according to the invention is expediently constructed such that it has an outer conductor sleeve made of conductive material, on one of which The contact lamellae are provided on the outside and the inner conductor socket is arranged on the inside and a coaxial cable is connected to the other end.

Wie bereits ausgeführt, ist das erfindungsgemäße Koaxial-Steckverbinderelement besonders gut für den Anschluß von Koaxialkabeln an eine NF-Stiftleiste geeignet. In diesem Fall ist es zweckmäßig, wenn das Steckverbinderelement zusammen mit weiteren gleichartigen Steckverbinderelementen in einem Steckergehäuse zu einer Einheit zusammengefaßt ist. Hinsichtlich der Verbindung des Koaxial-Steckverbinderelementes mit einer Stiftleiste ist es in solchen Fällen von Vorteil, wenn das Steckergehäuse mit einem zusammen mit einer Stiftleiste an einer Montageplatte vorgesehenen Übergabe-Stecker koppelbar ist.As already stated, the coaxial connector element according to the invention is particularly well suited for the connection of coaxial cables to an NF pin header. In this case, it is expedient if the connector element is combined to form a unit together with other similar connector elements in a connector housing. With regard to the connection of the coaxial connector element to a pin header, it is advantageous in such cases if the connector housing can be coupled to a transfer connector provided on a mounting plate together with a pin header.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes des Anspruchs 1 sind in den übrigen Unteransprüchen angegeben.Further advantageous embodiments of the subject matter of claim 1 are specified in the remaining subclaims.

Das Koaxial-Steckverbinderelement nach Fig. 1 besteht aus einer Außenleiterhülse 1 aus leitendem Material, an deren einem Ende ein Koaxialkabel 2 angeschlossen ist und deren anderes Ende in einer zur Verbindung mit einer NF-Stiftleiste geeigneten Weise ausgebildet ist. Hierzu ist das Steckverbinderelement am Außenumfang seines mit der Stiftleiste verbindbaren Endes mit vorzugsweise vier in gleichem Abstand voneinander angeordneten, nach außen vorstehenden, federnden Kontakt-Lamellen 3 ausgebildet, die bei der in Fig.1 dargestellten Ausführungsform von den Federarmen einer verdrehgesichert auf der Außenleiterhülse 1 fixierten Hülse 4 aus leitendem Material gebildet sind, sich vom Ende des Steckverbinderelementes weg in dessen Längsrichtung erstrecken und in unbelastetem Zustand schräg zu dessen Längsachse abstehen. Es sind jedoch auch andere Ausführungsformen von nach außen vorstehenden Kontakt-Lamellen möglich. Die Kontakt-Lamellen 3 dienen beim Aufstecken des Koaxial-Steckverbinderelementes auf eine Stiftleiste zur Kontaktherstellung mit Stiften, wobei bei vier in der dargestellten Weise angeordneten Kontakt-Lamellen vier an den Eckpunkten eines Quadrats liegende Stifte kontaktiert werden. Dieses Kontaktprinzip ist in Fig.2 veranschaulicht. Bei dem dort dargestellten 9er-Stiftfeld 5 werden die vier Stifte 6 durch Kontakt-Lamellen 3 kontaktiert und so mit der Außenleiterhülse 1 des Koaxial-Steckverbinderelements verbunden. Wie zu sehen ist, sind die Stifte des Stiftfeldes 5 hier mit gleichen Zwischenabständen von z.B. etwa 2,5 mm angeordnet und quadratisch ausgebildet, wobei sie einen Querschnitt von z.B. etwa 0,55 bis 0,65 mm haben können. Die Stifte können auch rund sein. Zur Verbindung des Koaxial-Steckverbinderelementes mit einer Stiftleiste ist es im Unterschied zur dargestellten Ausführungsform auch möglich, zwischen nur zwei einander diametral gegenüberliegenden Stiften und dementsprechend nur zwei in korrespondierender Weise an der Außenleiterhülse 1 vorgesehenen Kontakt-Lamellen einen Kontakt herzustellen.1 consists of an outer conductor sleeve 1 made of conductive material, at one end of which a coaxial cable 2 is connected and the other end of which is designed in a manner suitable for connection to an LF pin header. For this purpose, the connector element is formed on the outer circumference of its end which can be connected to the pin header, preferably with four resilient contact lamellae 3 which are arranged at the same distance from one another and which, in the embodiment shown in FIG fixed sleeve 4 are formed of conductive material, extend away from the end of the connector element in its longitudinal direction and project obliquely to its longitudinal axis in the unloaded state. However, other embodiments of outwardly projecting contact lamellae are also possible. The contact lamellae 3 are used when plugging the coaxial connector element onto a pin strip for making contact with pins, with four pins lying at the corner points of a square being contacted in the case of four contact lamellae arranged in the manner shown. This contact principle is illustrated in Fig.2. In the 9-pin array 5 shown there, the four pins 6 are contacted by contact lamellae 3 and thus connected to the outer conductor sleeve 1 of the coaxial connector element. As can be seen, the pins of the pin field 5 are arranged here with the same spacing of, for example, approximately 2.5 mm and are square, whereby they can have a cross section of, for example, approximately 0.55 to 0.65 mm. The pins can also be round. To connect the coaxial connector element to a pin header, it is also possible, in contrast to the embodiment shown, to connect only two diametrically opposite pins and accordingly only two in a corresponding manner on the External conductor sleeve 1 provided contact blades to make a contact.

An derjenigen Seite der Kontakt-Lamellen 3, welche der Stiftleiste zugewandt ist, ist auf der Außenleiterhülse 1 ein Ring 7 fixiert, z.B. aufgepreßt, der mit einer der Anzahl der Kontakt-Lamellen 3 entsprechenden Anzahl von Nuten 8, hier also mit vier Nuten versehen ist, die zu den Kontakt-Lamellen fluchten und nach außen offen sind. Dieser Ring dient mit seinen Nuten 8 der Vorpositionierung des Steckverbinderelementes, d.h. der Lagezuordnung zwischen den Kontakt-Lamellen 3 und den Stiften 6 des 9er-Stiftfeldes 5.On the side of the contact lamellae 3 which faces the pin strip, a ring 7 is fixed on the outer conductor sleeve 1, e.g. pressed on, which is provided with a number of grooves 8 corresponding to the number of contact blades 3, here here with four grooves, which are aligned with the contact blades and are open to the outside. With its grooves 8, this ring serves to preposition the connector element, i.e. the position assignment between the contact lamellae 3 and the pins 6 of the 9-pin field 5.

Zur Kontaktierung mit einem weiteren Stift, nämlich mit einem Mittelstift 9 des in Fig.2 dargestellten 9er-Stiftfeldes 5, der mittig innerhalb der Stifte 6 angeordnet ist, ist im Inneren des Steckverbinderelementes eine Innenleiterbuchse 10 aus leitendem Material vorgesehen, die gegenüber den Kontakt-Lamellen 3 fest positioniert ist. Hierzu ist die Innenleiterbuchse 10 von einem als Stützscheibe ausgebildeten Isolierteil 11 umgeben und durch deren Positioniernase 12 in der Außenleiterhülse 1 zentriert. Das Isolierteil 11 ist von der Kabelseite her in die Außenleiterhülse 1 eingeführt, wobei die Positioniernase 12 in einem Längsschlitz 13 der Außenleiterhülse geführt ist. Zwischen dem Isolierteil 11 und einem Durchmesserabsatz 14 an der Innenwandung der Außenleiterhülse 1 ist ein weiteres als Isolierhülse 15 ausgebildetes Isolierteil fixiert, deren vor der Innenleiterbuchse 10 liegende Stirnseite 16 eine Vorzentrierbohrung 17 für den in die Innenleiterbuchse einzuführenden Mittelstift 9 aufweist. An dem kabelseitigen Ende ist die Innenleiterbuchse 10 leitend mit dem abisolierten Innenleiter 18 des Koaxialkabels 2 verbunden, z.B. verlötet. Der von der Außenisolierung 19 befreite, z.B. aus einem Schirmgeflecht bestehende Außenleiter 20 des Koaxialkabels ist leitend mit der Außenleiterhülse 1 verbunden, z.B. ebenfalls verlötet, wozu die Außenleiterhülse mit einer geeigneten Anzahl von Lötlöchern 21 ausgebildet ist.In order to make contact with a further pin, namely with a center pin 9 of the 9-pin field 5 shown in FIG. 2, which is arranged centrally within the pins 6, an inner conductor socket 10 made of conductive material is provided in the interior of the plug connector element. Slats 3 is firmly positioned. For this purpose, the inner conductor socket 10 is surrounded by an insulating part 11 designed as a support disk and centered in the outer conductor sleeve 1 by its positioning lug 12. The insulating part 11 is inserted into the outer conductor sleeve 1 from the cable side, the positioning lug 12 being guided in a longitudinal slot 13 of the outer conductor sleeve. Between the insulating part 11 and a diameter shoulder 14 on the inner wall of the outer conductor sleeve 1, another insulating part designed as an insulating sleeve 15 is fixed, the end face 16 of which lies in front of the inner conductor socket 10 has a pre-centering hole 17 for the center pin 9 to be inserted into the inner conductor socket. At the cable end is the Inner conductor socket 10 conductively connected to the stripped inner conductor 18 of the coaxial cable 2, for example soldered. The outer conductor 20 of the coaxial cable, which is freed from the outer insulation 19, for example consisting of a shield braid, is conductively connected to the outer conductor sleeve 1, for example also soldered, for which purpose the outer conductor sleeve is formed with a suitable number of solder holes 21.

Ein Anwendungsbeispiel eines erfindungsgemäßen Koaxial-Steckverbinderelementes ist in Fig. 3 bzw. in Fig.6 gezeigt. Dort ist ein nach Fig. 1 mit vier Kontakt-Lamellen ausgebildetes Steckverbinderelement zusammen mit sieben weiteren gleichartigen Steckverbinderelementen jeweils als 8-fach-Stecker 30 in einem gemeinsamen Steckergehäuse 31 zu einer Einheit zusammengefaßt, welche jeweils zur Verbindung mit einem Feld von 9 x 5 - Stiften einer Stiftleiste 32 an einer Montageplatte 33, z.B. einer Geräterückwand oder einer Leiterplatte, dient, wobei das Steckergehäuse 31 mit einem Übergabe-Stecker 34 gekoppelt ist. Die Stiftleiste 32 ist wie in Fig.3 mit einer Baugruppe 35, z.B. einer Leiterplatte, oder wie in Fig.6 mit einer Federleiste 36 verbunden. Bei derartigen Anwendungsfällen ist es zweckmäßig, wenn die Außenleiter der Koaxialkabel mit dem jeweiligen Steckergehäuse 31 verbunden werden, so daß ein HF-dichter Koax-Schnittstellenübergang realisiert wird. Bei der Ausführungsform in Fig.3 sind die Kontakt-Lamellen 3a durch einen Kontaktbuckel 37 als nach außen vorstehend ausgebildet.An application example of a coaxial connector element according to the invention is shown in FIG. 3 or in FIG. 6. There, a connector element designed according to FIG. 1 with four contact lamellae, together with seven further similar connector elements, is combined as an 8-way connector 30 in a common connector housing 31 to form a unit, each for connection to a field of 9 × 5 mm. Pins a pin header 32 on a mounting plate 33, for example a rear wall of the device or a printed circuit board, the connector housing 31 being coupled to a transfer connector 34. The pin header 32 is as in Figure 3 with an assembly 35, e.g. a circuit board, or as connected in Figure 6 with a female connector 36.
