Description

Die Erfindung bezieht sich auf einen Steckverbinder zur elektrisch leitenden Verbindung von Leiterbahnen einer Platine mit zumindest einem Koaxialkabei nach dem Oberbegriff des Anspruchs 1.The invention relates to a plug connector for the electrically conductive connection of conductor tracks of a circuit board with at least one coaxial cable according to the preamble of claim 1.

Derartige Steckverbinder finden Verwendung, um die Übertragung von Hochfrequenzsignalen zwischen einer Platine und einem diese kontaktierenden Kabel zu ermöglichen.Such connectors are used to enable the transmission of high-frequency signals between a circuit board and a cable contacting it.

Der Erfindung liegt das Problem zugrunde, einen baulich sehr flachen Steckverbinder zu schaffen, der eine zuverlässige Kontaktierung ermöglicht.The invention is based on the problem of creating a structurally very flat connector which enables reliable contacting.

Die Erfindung löst dieses Problem durch einen Steckverbinder mit den Merkmalen des Anspruchs 1.The invention solves this problem by a connector having the features of claim 1.

Hinsichtlich weiterer vorteilhafter Ausgestaltungen wird auf die Ansprüche 2 bis 12 verwiesen.With regard to further advantageous refinements, reference is made to claims 2 to 12.

Durch die erfindungsgemäße Ausbildung eines Steckverbinders kann dieser parallel nebeneinanderliegende Einschubkanäle aufnehmen, die ohne eine Abknickung in ihrem Verlauf auskommen und senkrecht zu ihrem Verlauf durch eingeschobene Steckkontakte zuverlässig kontaktiert sind. Die Bauhöhe des Steckverbinders kann dabei sehr gering gehalten werden; der Steckverbinder im Ausführungsbeispiel hat eine Höhe von etwa 7 mm.By designing a connector according to the invention, the connector can accommodate parallel insertion channels which manage without a kink in their course and are reliably contacted perpendicularly to their course by inserted plug contacts. The overall height of the connector can be kept very low; the connector in the embodiment has a height of about 7 mm.

Die Kontaktierung ist besonders zuverlässig, wenn für die Abschirmung eines Koaxialkabels zwei Steckkontakte vorgesehen sind, die in diese Abschirmung einschneiden, und für den Zentralleiter ein weiterer Steckkontakt vorgesehen ist.The contacting is particularly reliable if two plug contacts are provided for the shielding of a coaxial cable, which cut into this shield, and a further plug contact is provided for the central conductor.

Bei Vorsehen einer integral mit dem Gehäuse des Steckverbinders ausgebildeten Zugentlastung ist bei konstruktiv geringem Aufwand eine zuverlässige Kabelhalterung in dem Steckverbinder sichergestellt.If a strain relief is formed integrally with the housing of the connector, a reliable cable holder is ensured in the connector with little construction.

Besonders vorteilhaft sind in dem Steckverbinder mehrere Koaxialkabel und Einzelleiter, etwa zur Spannungsversorgung, in Parallellage nebeneinander angeordnet, wodurch die Bauhöhe des Steckverbinders nicht vergrößert wird. Eine vollständige Kontaktierung der Platine, die von seitlichen Randanformungen des Steckverbinders haltend umgriffen werden kann, ist dadurch ermöglicht.Several coaxial cables and individual conductors, for example for the voltage supply, are particularly advantageously arranged in parallel in the connector, as a result of which the overall height of the connector is not increased. This enables complete contacting of the circuit board, which can be held around by lateral edge formations of the connector.

Weitere Vorteile und Einzelheiten ergeben sich aus einem in der Zeichnung dargestellten Ausführungsbeispiel des Gegenstandes der Erfindung.Further advantages and details emerge from an exemplary embodiment of the subject matter of the invention shown in the drawing.

Der in der Zeichnung dargestellte Steckverbinder 1,101 weist in seinem mittleren Bereich mehrere nebeneinanderliegende Einschubkanäle 2 für Koaxialkabel auf, die über ihren Längsverlauf jeweils eine Abstufung 3 aufweisen, die einen vorderen Endbereich 4 zur Aufnahme des zentralen Innenleiters des Koaxialkabels von einem hinteren Endbereich 5 zur Aufnahme des Koaxialkabels mit Innenleiter und äußerer Abschirmung trennt.The connector 1, 101 shown in the drawing has, in its central region, a plurality of insertion channels 2 for coaxial cables lying next to one another, each of which has a gradation 3 over its longitudinal course, which has a front end region 4 for receiving the central inner conductor of the coaxial cable from a rear end region 5 for receiving the Separates coaxial cable with inner conductor and outer shield.

Der vordere Endbereich 4 weist gegenüber dem hinterem Endbereich 5 einen verringerten Durchmesser auf, derart, daß dieser den Durchmesser der Abschirmung unterschreitet, so daß von dem Koaxialkabel die Abschirmung zumindest über die Länge des vorderen Endbereiches 4 entfernt werden muß.The front end region 4 has a reduced diameter compared to the rear end region 5, such that this falls below the diameter of the shield, so that the shield must be removed from the coaxial cable at least over the length of the front end region 4.

In dem Steckverbinder 1 gemäß den Figuren 1 bis 8 sind Schlitzausnehmungen 6,7,8 vorgesehen, die zur Aufnahme von Steckkontakten 9,10 ausgebildet sind. Für jeden Einschubkanal 2 sind eine dem vorderen Endbereich 4 zugeordnete Schlitzausnehmung 6 sowie zwei dem hinteren Endbereich 5 zugeordnete Schlitzausnehmungen 7 vorgesehen, wobei die Schlitzausnehmung 6 den zentralen Leiter radial zum Endbereich 4 des Einschubkanals 2 schneidet. Die beiden hinteren Schlitzausnehmungen 7 sind derart angeordnet, daß die dort einzuschiebenden Steckkontakte 10 die Abschirmung des Koaxialkabels im wesentlichen tangential schneiden. Zur Kontaktierung werden zunächst die Koaxialkabel nach teilweiser Entfernung der Abschirmung in den Einschubkanal 2 eingeschoben, dann werden die Steckkontakte 9,10 in die Schlitzausnehmungen 6,7 eingedrückt, wodurch die jeweiligen Leiter angeschnitten und damit leitend mit den Steckkontakten 9,10 verbunden werden. Hierfür weisen die Steckkontakte 9,10 jeweils zumindest eine Spitze 11 auf. Auf der gegenüberliegenden Seite sind die Steckkontakte 9,10 mit Federbügeln 12 versehen, die auf die jeweilige Leiterbahn 23,24,25 der Platine 21 einen Druck ausüben, der für eine zuverlässige Kontaktierung sorgt.In the plug connector 1 according to FIGS. 1 to 8, slot recesses 6, 7, 8 are provided, which are designed to receive plug contacts 9, 10 are. For each insertion channel 2, a slot recess 6 assigned to the front end region 4 and two slot recesses 7 assigned to the rear end region 5 are provided, the slot recess 6 cutting the central conductor radially to the end region 4 of the insertion channel 2. The two rear slot recesses 7 are arranged such that the plug contacts 10 to be inserted there cut the shielding of the coaxial cable essentially tangentially. For contacting, the coaxial cables are first inserted into the insertion channel 2 after the shield has been partially removed, then the plug contacts 9, 10 are pressed into the slot recesses 6, 7, whereby the respective conductors are cut and thus conductively connected to the plug contacts 9, 10. For this purpose, the plug contacts 9, 10 each have at least one tip 11. On the opposite side, the plug contacts 9, 10 are provided with spring clips 12, which exert pressure on the respective conductor track 23, 24, 25 of the circuit board 21, which ensures reliable contacting.

Im Ausführungsbeispiel sind die Steckkontakte 9,10 für den Innenleiter bzw. die Abschirmung gleichartig ausgebildet, so daß hierfür nur die Bereitstellung einer Bauteilart erforderlich ist.In the exemplary embodiment, the plug contacts 9, 10 for the inner conductor or the shield are of the same design, so that only one type of component is required for this.

Neben den im Ausführungsbeispiel vier zentralen Einschubkanälen 2 für Koaxialkabel weist der Steckverbinder 1,101 in seinen Außenbereichen in der Ebene der Einschubkanäle 2 drei weitere Leitungskanäle 13 auf, die einadrige Kabel aufnehmen, beispielsweise zur Spannungsversorgung oder für eine Übertragung eines niederfrequenten Signals. Die weiteren Leitungskanäle 13 liegen symmetrisch zu den Einschubkanälen 2 und verfügen ebenfalls über Schlitzausnehmungen 8, die zur Einführung von Steckkontakten vorgesehen sind. Diese können gleichartig zu den sonstigen verwendeten Steckkontakten 9,10 ausgebildet sein.In addition to the four central insertion channels 2 for coaxial cables in the exemplary embodiment, the plug-in connector 1, 101 has three further line channels 13 in its outer regions in the level of the insertion channels 2, which receive single-core cables, for example for voltage supply or for transmission of a low-frequency signal. The other line channels 13 are symmetrical to the insertion channels 2 and also have slot recesses 8 which are provided for the insertion of plug contacts. These can be designed in the same way as the other plug contacts 9, 10 used.

Sowohl für die seitlichen Leitungskanäle 13 als auch für die zentralen Koaxialeinschubkanäle 2 sind im hinteren Bereich des Steckers Zugentlastungen 14,15 vorgesehen. Bei einteiliger Gehäuseausbildung des Steckverbinders 1, beispielsweise als Kunststoffgehäuse, ist die Zugentlastung 14 bzw. 15 jeweils einstückig mit dem Gehäuse ausgebildet und kann um ein Filmscharnier 16 in eine geschlossene Stellung verschwenkt werden, in der sie hinter einer Gegenkante 17 festgelegt ist und mit einer Spitze 18 das Kabel kraftschlüssig in dem jeweiligen Kanal 2,13 hält. Aufgrund der Einstückigkeit mit dem Gehäuse ist eine derartige Zugentlastung 14,15 in der Herstellung besonders preiswert.Strain relief devices 14, 15 are provided in the rear area of the plug both for the lateral line ducts 13 and for the central coaxial insertion ducts 2. In the case of a one-piece housing design of the connector 1, for example as a plastic housing, the strain relief 14 or 15 is formed in one piece with the housing and can be pivoted about a film hinge 16 into a closed position in which it is fixed behind a counter edge 17 and with a tip 18 holds the cable non-positively in the respective channel 2.13. Due to the one-piece construction with the housing, such a strain relief 14, 15 is particularly inexpensive to manufacture.

Bei Übertragung von Hochfrequenzsignalen, insbesondere im Bereich von Frequenzen, die größer als 1 GHz sind, ist ein Abschirmkamm 19 vorgesehen, der aus elektrisch leitendem Material ausgebildet ist und die Einschubkanäle 2 voneinander abtrennt, um damit eine Signalübertragung zwischen den Koaxialleitern zu verhindern.When transmitting high-frequency signals, in particular in the range of frequencies that are greater than 1 GHz, a shielding comb 19 is provided, which is made of electrically conductive material and separates the insertion channels 2 from one another, in order to thereby prevent signal transmission between the coaxial conductors.

Der Steckverbinder 1,101 weist unterseitige Ansätze 20 auf, die um den Randbereich einer Platine 21 greifen und dadurch den Steckverbinder 1 auf der Platine 21 halten. Die Platine kann Ansätze 22 aufweisen, die einen Anschlag für den aufzuschiebenden Steckverbinder 1,101 darstellen. Die Leiterbahnen 23,24,25 der Platine, die in Kontakt mit dem Steckverbinder 1,101 stehen, sind an die ensprechende Anordnung der Steckverbinder angepaßt; es stehen also jeweils zwei Leiterbahnen 24 für die Kontaktierung der Abschirmung symmetrisch zu einer zentralen Leiterbahn 25 für die Kontaktierung der Innenleiter. Im Außenbereich verlaufen jeweils drei Leiterbahnen 23 für die niederfrequenten bzw. eine Gleichspannung übertragenden Einzelleiter, die in die Leitungskanäle 13 eingeschoben werden.The connector 1, 101 has lugs 20 on the underside which engage around the edge region of a circuit board 21 and thereby hold the connector 1 on the circuit board 21. The circuit board can have lugs 22, which represent a stop for the plug-in connector 1, 101. The conductor tracks 23, 24, 25 of the board, which are in contact with the connector 1, 101, are adapted to the corresponding arrangement of the connectors; So there are two conductor tracks 24 for contacting the shield symmetrical to a central conductor track 25 for contacting the inner conductor. Three conductor tracks 23 each run in the outer region for the low-frequency individual conductors or for transmitting a direct voltage, which are inserted into the line channels 13.

Gemäß einem alternativen Ausführungsbeispiel (Figuren 9 bis 11) sind bei ansonsten gleichartiger Ausbildung zum ersten Ausführungsbeispiel die drei Steckkontakte 9, 10 in einer axialen Höhe des Steckverbinders 101 nebeneinander angeordnet.
Auch in dieser Anordnung kontaktiert der mittlere Steckkontakt 9 den zentralen Leiter im vorderen Bereich 4 des Einschubkanals 2, die äußeren Steckkontakte 10 hingegen kontaktieren die äußere Abschirmung im hinteren Bereich 5 des Einschubkanals 2. Durch diese Lage der Steckkontakte 9,10 nebeneinander ist das Abschirmverhalten verbessert.
Die äußeren Steckkontakte 10 weisen Kontaktspitzen 11 auf, die sich in den erweiterten Bereich des Einschubkanals 2 erstrecken, so daß hier die äußere Abschirmung des eingedrückten Kabels angeschnitten und kontaktiert werden kann. Die dem schmaleren Bereich 4 des Einschubkanals 2 zugeordneten Spitzen 11 haben dabei keine Kontaktwirkung, da sie neben dem Innenleiter liegen. Diese Spitzen 11 könnten auch entfernt werden.According to an alternative exemplary embodiment (FIGS. 9 to 11), with an otherwise similar design to the first exemplary embodiment, the three are Plug contacts 9, 10 arranged side by side at an axial height of the connector 101.
In this arrangement, too, the middle plug contact 9 contacts the central conductor in the front area 4 of the insertion channel 2, while the outer plug contacts 10 contact the outer shield in the rear area 5 of the insertion channel 2. This position of the plug contacts 9, 10 next to one another improves the shielding behavior .
The outer plug contacts 10 have contact tips 11 which extend into the expanded area of the insertion channel 2, so that the outer shield of the pressed-in cable can be cut and contacted here. The tips 11 assigned to the narrower area 4 of the insertion channel 2 have no contact effect since they lie next to the inner conductor. These tips 11 could also be removed.

Der Steckkontakt 9 zur Kontaktierung des zentralen Leiters im vorderen Bereich 4 des Einschubkanals 2 weist hingegen gemäß Fig. 11 nur in dem dem vorderen Bereich 4 zugewandten Teil Kontaktspitzen 11 auf, im anderen Seitenbereich des Steckkontaktes können diese Spitzen beispielsweise abgekniffen sein, so daß trotz dieses Unterschiedes eine zunächst gleichartige Serie von Steckkontakten 9,10 Verwendung finden kann. Bei Eindrücken des Steckkontakts 9 in die in einer Linie mit den äußeren Schlitzausnehmungen 107 liegende Schlitzausnehmung 106 wird dann nur der zentrale Innenleiter im vorderen Bereich 4 kontaktiert, die Abschirmung wird in Ermangelung von Kontaktspitzen nicht angeschnitten und somit auch nicht kontaktiert.The plug contact 9 for contacting the central conductor in the front area 4 of the insertion channel 2, on the other hand, according to FIG. 11, has contact tips 11 only in the part facing the front area 4, in the other side area of the plug contact these tips can be pinched off, so that despite this Difference an initially similar series of plug contacts 9, 10 can be used. When the plug contact 9 is pressed into the slot recess 106 lying in a line with the outer slot recesses 107, only the central inner conductor in the front region 4 is then contacted; the shield is not cut in the absence of contact tips and thus is not contacted either.

In der Fig. 12 ist ein Steckverbinder 201 mit einer modifizierten Zugentlastung 214 gezeigt, der im wesentlichen wie der in der Fig. 1 dargestellte und vorstehend beschriebene Steckverbinder ausgebildet ist. Die Zugentlastung ist jedoch so gestaltet, daß sie im eingeschwenkten Zustand den Abschluß des Steckergehäuses bildet.FIG. 12 shows a plug connector 201 with a modified strain relief 214, which is essentially designed like the plug connector shown in FIG. 1 and described above. The strain relief is designed so that it forms the end of the connector housing in the pivoted state.

Dabei zeigt Fig. 12 einen Schnitt durch den Steckverbinder, mit dem Einschubkanal 202, der in den hinteren, aufgeweiteten Bereich 205 und den vorderen Bereich 204 unterteilt ist.12 shows a section through the plug connector, with the insertion channel 202, which is divided into the rear, widened region 205 and the front region 204.

Die mittels eines am äußeren Gehäuserand angeformten Filmscharnieres 216 gehaltene Zugentlastung 214 ist mit konisch geformten Stiften 226 (von denen hier nur einer exemplarisch dargestellt ist) versehen, die beim Schließen der Zugentlastung in Ausnehmungen 227 der gegenüberliegende Gehäusewandung eintauchen und deren ggf. überstehendes Ende durch einen thermischen Prozeß (Warmschweißen) mit der Gehäusewandung verschweißt werden kann, um eine dauerhafte Klemmung eines Kabels zu gewährleisten.The strain relief 214 held by means of a film hinge 216 formed on the outer edge of the housing is provided with conically shaped pins 226 (only one of which is shown here by way of an example) which, when the strain relief is closed, are immersed in recesses 227 of the opposite housing wall and their possibly protruding end by one thermal process (hot welding) can be welded to the housing wall to ensure permanent clamping of a cable.

Die konisch geformten Stifte 226 sind horizontal so nebeneinander angeordnet, daß sie beim Schließen der Zugentlastung jeweils in Zwischenräume der Kabel bzw. Koaxialkabel geschoben werden und auf Grund der schrägen Formgebung die Kabel festklemmen, wobei die Abstände und Größe der konisch geformten Stifte 226 auf die unterschiedlichen Durchmesser der Koaxialkabel und der Einzelleiter angepaßt sind.The conically shaped pins 226 are arranged horizontally next to each other so that when the strain relief is closed they are pushed into spaces between the cables or coaxial cables and, due to the oblique shape, clamp the cables, the spacing and size of the conically shaped pins 226 depending on the different ones Diameters of the coaxial cables and the individual conductors are adapted.
