Abstract

In a plug (1) with a two-part plug housing (4), the cable connecting arrangement (6) has a supporting sleeve (15) slidable over the connection cable (7) and provided with a contact part (19) for the cable shield (20) which is reversed on the contact part and clamped thereon by means of a ring-shaped crimping element (14). The supporting sleeve (15) is further designed with a flange (22) and is screwed with a coupling ring (16) in such a way that the front walls (8, 9) of the plug housing (4) are clamped between the flange and the coupling ring. A shielded cable connection with a reliable strain relief is thus obtained for a reopenable plug housing.

Description

Geschirmter Stecker mit KabelanschlußShielded plug with cable connection

Die Erfindung betrifft einen geschirmten Stecker mit einem aus zwei leitend ausgebildeten Teilen zusammengesetzten Steckergehäuse, an dessen Kabeleinführseite ein geschirm¬ tes Anschlußkabel mittels einer ein Cri pelement aufwei- senden Kabelanschlußeinrichtung angeschlossen ist.The invention relates to a shielded plug with a connector housing composed of two conductive parts, on the cable entry side of which a shielded connecting cable is connected by means of a cable connecting device having a crimp element.

Durch das DE-G 87 13 046 ist ein geschirmter Stecker mit einem zweiteiligen Gehäuse und einer Kabelanschlußein¬ richtung bekannt, die außer einer insbesondere als Knick- schütz für das Kabel dienenden Tülle eine Doppelschelle umfaßt, wobei der eine Teil der Doppelschelle die Zugent¬ lastung am Kabelmantel und der andere Teil die Kontaktie- rung des Kabelschirmes übernimmt. Die Doppelschelle ist auf den Kabelmantel und den Kabelschirm ausgerichtet, liegt auf einer Seite des Kabels auf und wird durch Fest¬ schrauben mechanisch mit dem Gehäuseunterteil verbunden, wobei der Kabelschirm elektrisch mit dem Schirmblech des Gehäuseunterteiles kontaktiert wird. Bei einem derartigen Kabelanschluß ergibt sich keine geschlossen umlaufende Kontaktierung des Kabelschirmes. Außerdem besteht die Möglichkeit, daß das Kabel zur Erzielung einer zuver¬ lässigen Zugentlastung zu stark gequetscht wird.DE-G 87 13 046 discloses a shielded plug with a two-part housing and a cable connection device which, in addition to a grommet serving in particular as a kink protection for the cable, comprises a double clamp, one part of the double clamp relieving the strain on the cable jacket and the other part takes over the contacting of the cable shield. The double clamp is aligned with the cable jacket and the cable shield, lies on one side of the cable and is mechanically connected to the lower housing part by means of screws, the cable shield being electrically contacted with the shield plate of the lower housing part. With such a cable connection there is no closed peripheral contacting of the cable shield. There is also the possibility that the cable is squeezed too much to achieve a reliable strain relief.

Ferner ist ein Stecker für ein geschirmtes Übergabesystem im Handel, der zwei U-förmige metallene Gehäusehalbschalen besitzt, die am Kabeleinführende jeweils eine halbkreis¬ förmige Einführstutzenhälfte aufweisen. Mittels einer über den Einführstutzen und den Kabelschirm geschobenen Crimp- hülse, die mit einer Zange verformt wird, wird bei einem derartigen Stecker eine Schirmkontaktierung und gleich¬ zeitig eine mechanische Verbindung der Gehäusehalbschalen im Bereich des Einführstutzens erreicht. Im zusammenge¬ setzten Zustand bei verformter Crimphülse läßt sich dann das Steckergehäuse nicht mehr öffnen. Außerdem ist für die Verformung eine mit Einsätzen für unterschiedliche Durch¬ messer zu versehende relativ teuere Spezialzange erforder- lieh.Furthermore, a connector for a shielded transfer system is on the market, which has two U-shaped metal housing half-shells, each of which has a semicircular entry socket half at the cable entry. By means of a The crimp sleeve pushed into the insertion socket and the cable shield, which is deformed with pliers, achieves shield contacting and, at the same time, mechanical connection of the housing half-shells in the region of the insertion socket with such a plug. In the assembled state with the crimp sleeve deformed, the plug housing can then no longer be opened. In addition, a relatively expensive special pliers to be provided with inserts for different diameters is required for the deformation.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Stecker der eingangs genannten Art auf einfache Weise, bei zuverlässiger Zugentlastung, aber geringstmöglicher Deformation des Kabelquerschnittes eine gute Schirmung des Kabelanschlusses zu erreichen.The invention has for its object to achieve good shielding of the cable connection in a plug of the type mentioned in a simple manner, with reliable strain relief, but the least possible deformation of the cable cross section.

Diese Aufgabe wird gemäß der Erfindung durch folgende Merkmale gelöst:This object is achieved according to the invention by the following features:

a) Die Kabelanschlußeinrichtung umfaßt außer dem Crimp- element eine über das Anschlußkabel schiebbare metallene Stützhülse und eine Überwurfmutter, b) die Stützhülse ist an einem Ende mit einem ein Außen- gewinde aufweisenden Gewindeteil zur Verschraubung mit der Überwurfmutter und am anderen Ende mit einem spann¬ zangenartigen geschlitzten Kontaktteil für den Kabelschirm sowie zwischen dem Gewindeteil und dem Kontaktteil mit einem radial abstehenden Flansch ausgebildet, c) der Kabelschirm ist über das Kontaktteil umgestülpt und mittels des Crimpelementes fest gegen das Kontaktteil gedrückt, d) die Teile des Steckergehäuses sind an der Kabelein¬ führseite jeweils mit einer Stirnwand und einer in dieser vorgesehenen, zum jeweils anderen Teil hin offenen Ausnehmung zur Einführung der Kabelanschlußeinrichtung ausgebildet, e) zur mechanischen Verbindung zwischen dem Steckerge¬ häuse und der Kabelanschlußeinrichtung sowie zur Kontak- tierung des Kabelschirmes mit dem Steckergehäuse sind die Stirnwände der zusammengesetzten Teile des Steckergehäuses zwischen dem Flansch der Stützhülse und der auf das Gewinde- teil der Stützhülse aufgeschraubten Überwurfmutter fest eingespannt.a) In addition to the crimping element, the cable connection device comprises a metal support sleeve which can be pushed over the connection cable and a union nut, b) the support sleeve is at one end with a threaded part having an external thread for screwing with the union nut and at the other end with a tensioning member pliers-like, slotted contact part for the cable shield and between the threaded part and the contact part with a radially projecting flange, c) the cable shield is turned over the contact part and pressed firmly against the contact part by means of the crimping element, d) the parts of the plug housing are each formed on the cable entry side with an end wall and a recess provided therein, which is open towards the other part for the insertion of the cable connection device, e) for the mechanical connection between the plug housing and the cable connection device and for Contacting the cable shield with the connector housing, the end walls of the assembled parts of the connector housing are firmly clamped between the flange of the support sleeve and the union nut screwed onto the threaded part of the support sleeve.

Bei einem derartigen Stecker ist der Kabelanschluß mit einfachsten Werkzeugen in einem separaten Montageschritt und ergonomisch günstig in der Handhabung durchführbar, wobei bei geringstmöglichster Deformation des Kabelquer¬ schnitts (Kreisform) eine sichere Schirmkontaktierung bei zuverlässiger mechanischer Zugentlastung erreicht wird. Da das Kontaktteil der Stützhülse Schlitze hat und wie eine Spannzange zusammengedrückt werden kann, bis dieIn the case of such a plug, the cable connection can be carried out with the simplest tools in a separate assembly step and is ergonomically favorable to handle, with the least possible deformation of the cable cross-section (circular shape) ensuring reliable shield contacting with reliable mechanical strain relief. Since the contact part of the support sleeve has slots and can be compressed like a collet until the

Schlitze geschlossen sind, ergibt sich ein geschlossener Durchmesser, so daß das Kontaktteil als geschlossener Ring in den Kabelmantel gedrückt werden kann und eine gute umlaufende Schirmung erreicht wird. Außerdem läßt sich trotz Einsatzes eines Crimpelementes der Kabelanschluß einfach vom Steckergehäuse bzw. von dessen Teilen abnehmen und das Steckergehäuse wieder öffnen. Schließlich ist bei einem derartigen Kabelanschluß auch der nachteilige Ein¬ fluß von Kaltflußeigenschaften und Alterungserscheinungen bei Kunststoffen ausgeschlossen. In vorteilhafter Weise ist bei einem erfindungsgemäßen Stecker das Kontaktteil der Stützhülse zumindest mit einigen Innengewindegängen versehen. Damit kann die Stütz¬ hülse mit leichter Vorspannung auf den Kabelmantel ge¬ schraubt werden, um einen definierten Sitz der Stützhülse zu gewährleisten.Slits are closed, there is a closed diameter, so that the contact part can be pressed as a closed ring in the cable jacket and a good all-round shielding is achieved. In addition, despite the use of a crimping element, the cable connection can easily be removed from the connector housing or its parts and the connector housing opened again. Finally, the disadvantageous influence of cold flow properties and signs of aging in plastics is also excluded with such a cable connection. In an advantageous manner, in a connector according to the invention the contact part of the support sleeve is provided with at least some internal threads. The support sleeve can thus be screwed onto the cable sheath with a slight prestress in order to ensure a defined fit of the support sleeve.

Im Hinblick auf die Verschraubung zwischen der Überwurf¬ mutter und der Stützhülse sowie die mechanische Verbindung der beiden Teile des Steckergehäuses ist es von Vorteil, wenn an der Stirnwand der Teile des Steckergehäuses jeweils ein senkrecht abstehender, die Ausnehmung zumin¬ dest teilweise umgebender Kragen vorgesehen ist, und wenn der Abstand zweier einander diametral gegenüberliegender. Kragen im zusammengesetzten Zustand der Teile des Stecker- gehauses kleiner ist als der Innendurchmesser der Überwurf¬ mutter. In diesem Fall übergreift die aufgeschraubte Über¬ wurfmutter die Stirnwand-Kragen und sichert den Zusammen¬ halt der beiden Teile des Steckergehäuses zuverlässig.With regard to the screw connection between the union nut and the support sleeve and the mechanical connection of the two parts of the plug housing, it is advantageous if a vertically protruding collar, which at least partially surrounds the recess, is provided on the end wall of the parts of the plug housing , and if the distance between two diametrically opposite one another. Collar in the assembled state of the parts of the connector housing is smaller than the inside diameter of the union nut. In this case, the screwed-on union nut overlaps the end wall collar and reliably secures the two parts of the connector housing together.

Der Stecker 1 besteht - wie die Fig. 1 und 2 zeigen - aus einem aus zwei leitend ausgebildeten Teilen, z.B. aus zwei metallenen Halbschalen 2 und 3 zusammengesetzten Stecker- gehäuse 4 mit einem Steckereinsatz 5 und einer Kabelan¬ schlußeinrichtung 6 für das Anschlußkabel 7. Die Halb¬ schalen 2 und 3 des Steckergehäuses 4 sind zweckmäßiger¬ weise von Blechstanzbiegeteilen gebildet, welche an der Kabeleinführseite jeweils mit einer Stirnwand 8 bzw. 9 und einer in dieser vorgesehenen, zur anderen Halbschale hin offenen Ausnehmung 10 bzw. 11 zur Einführung der Kabelanschlußeinrichtung 6 ausgebildet sind. Die Aus¬ nehmungen 10,11 sind langlochartig in den zur Steck¬ richtung hier senkrechten Stirnwänden 8 und 9 vorgesehen und an ihrem bogenförmigen Ende jeweils von einem senkrecht zu der jeweiligen Stirnwand abstehenden Kragen 12 bzw. 13 umgeben. Wie die Fig.l zeigt, ist in die eine Halbschale 3 der Steckereinsatz 5 mit dem über die Kabel- anschlußeinrichtung 6 angeschlossenen Anschlußkabel 7 ein- geführt, während die andere Halbschale 2 - wie die Fig. 2 zeigt - als Deckel den Stecker geschirmt abschließt.The connector 1 - as shown in Figs. 1 and 2 - consists of one of two conductive parts, e.g. from two metal half-shells 2 and 3 assembled connector housing 4 with a plug insert 5 and a cable connection device 6 for the connecting cable 7. The half-shells 2 and 3 of the connector housing 4 are expediently formed by sheet metal stamping parts, each on the cable entry side are formed with an end wall 8 and 9 and a recess 10 and 11 provided therein, which is open toward the other half-shell, for introducing the cable connection device 6. The recesses 10, 11 are provided in the manner of an elongated hole in the end walls 8 and 9 which are perpendicular to the plug-in direction and are each surrounded at their arcuate end by a collar 12 and 13 projecting perpendicularly to the respective end wall. As shown in FIG. 1, the plug insert 5 with the connecting cable 7 connected via the cable connection device 6 is inserted into one half-shell 3, while the other half-shell 2 — as FIG. 2 shows — closes the plug in a shielded manner as a cover .

Die Kabelanschlußeinrichtung umfaßt - wie die Fig.3 zeigt - ein ringförmiges Crimpelement 14, eine über das Anschluß- kabel 7 schiebbare metallene Stützhülse 15 und eine rela¬ tiv flache, ebenfalls metallene Überwurfmutter 16. Die Stützhülse 15 ist an einem Ende mit einem ein Außen¬ gewinde 17 aufweisenden Gewindeteil 18 zur Verschraubung mit der Überwurfmutter 16 und am anderen Ende mit einem spannzangenartigen geschlitzten Kontaktteil 19 für den Kabelschirm 20 ausgebildet, welches hier zumindest mit einigen Innengewindegängen 21 versehen ist. Zwischen dem Gewindeteil 18 und dem Kontaktteil 19 weist die Stützhülse 15 einen radial abstehenden Flansch 22 auf, der - ins¬ besondere wenn die Stützhülse aus einem sechskantigen Material hergestellt ist - eine Sechskant-U fangsform hat, wobei die Schlüsselweite des Flansches 22 größer ist als die lichte Innenweite - hier die Breite - der in den Stirnwänden 8,9 vorgesehenen Ausnehmung 10 bzw. 11.As shown in FIG. 3, the cable connection device comprises an annular crimp element 14, a metal support sleeve 15 which can be pushed over the connection cable 7 and a relatively flat, likewise metal union nut 16. The support sleeve 15 is formed at one end with an external thread 17 having a threaded part 18 for screwing with the union nut 16 and at the other end with a collet-like slotted contact part 19 for the cable shield 20, which here is provided with at least some internal threads 21. Between the threaded part 18 and the contact part 19, the support sleeve 15 has a radially projecting flange 22 which, in particular if the support sleeve is made of a hexagonal material, has a hexagonal U-shaped shape, the width across flats 22 being greater than the clear inside width - here the width - of the recess 10 or 11 provided in the end walls 8, 9.

Die Kabelanschlußeinrichtung 6 wird in einem separaten Montageschritt an dem Anschlußkabel 7 vormontiert. Dazu wird die Stützhülse 15 samt Überwurfmutter 16 über das abisolierte Anschlußkabel 7 geschoben und mit seinen Innengewindegängen 21 auf den Kabelmantel geschraubt. Nun wird der Kabelschirm 20 über das Kontaktteil 19 umgestülpt, das ringförmige Crimpelement 14 darüberge- schoben und mittels einer einfachen Zange an zwei einander diametral gegenüberliegenden verformten Stellen 23,24 weiter zusammengedrückt und gespannt. Dadurch drückt das Crimpelement 14 den Kabelschirm 20 fest auf das Kontakt- teil 19, welches mit seinen Innengewindegängen 21 weiter in den Kabelmantel eindringt, bis die Schlitze geschlossen sind und ein geschlossener Durchmesser entsteht. Das Anschlußkabel ist damit für den Einbau in das Steckerge- häuse 4 vorbereitet. Das derart mit der Kabelanschlußein¬ richtung 6 vormontierte, in Fig. 4 dargestellte Anschlu߬ kabel 7 ist nun - wie Fig. 1 zeigt -so in die Halbschale 3 des Steckergehäuses 4 eingeführt, daß der Flansch 22 der Stützhülse 15 sich innerhalb dieser Halbschale, d.h. unter deren Stirnwand 9, befindet. Nach dem Zusammenstecken der Halbschalen 2 und 3 wird dann die Überwurfmutter 16 festgeschraubt, so daß die Stirnwände 8,9 der zusammen¬ gesetzten Teile des Steckergehäuses zwischen dem Flansch 22 der Stützhülse 15 und der auf das Gewindeteil 18 der Stützhülse aufgeschraubten Überwurfmutter 16 fest eingespannt sind. Damit ist die mechanische Verbindung zwischen dem Steckergehäuse 4 und der Kabelanschlußein¬ richtung 6 hergestellt, wobei aufgrund einer entsprechen- den lichten Außenweite der zwei einander diametral gegen¬ überliegenden Kragen 12,13 die Überwurfmutter 16 diese Kragen übergreift. Außerdem ist im festgeschraubten Zustand der Überwurfmutter 16 die Kontaktierung des Kabelschirmes am Steckgehäuse 4 hergestellt.The cable connection device 6 is preassembled on the connection cable 7 in a separate assembly step. For this purpose, the support sleeve 15 together with the union nut 16 is pushed over the stripped connecting cable 7 and screwed with its internal threads 21 onto the cable sheath. Now the cable shield 20 is turned over the contact part 19, the ring-shaped crimp element 14 is pushed over it and further compressed and stretched by means of a simple pair of pliers at two diametrically opposed deformed points 23, 24. As a result, the crimping element 14 presses the cable shield 20 firmly onto the contact part 19, which with its internal threads 21 penetrates further into the cable sheath until the slots are closed and a closed diameter is created. The connection cable is thus prepared for installation in the connector housing 4. The connecting cable 7 shown in FIG. 4 and thus pre-assembled with the cable connection device 6 is now - as shown in FIG. ie under whose end wall 9 is located. After the half-shells 2 and 3 have been plugged together, the union nut 16 is then screwed tight, so that the end walls 8, 9 of the assembled parts of the connector housing are firmly clamped between the flange 22 of the support sleeve 15 and the union nut 16 screwed onto the threaded part 18 of the support sleeve . The mechanical connection between the plug housing 4 and the cable connection device 6 is thus established, the union nut 16 engaging over these collars due to a corresponding clear outer width of the two diametrically opposite collars 12, 13. In addition, the contact of the cable shield on the plug housing 4 is made in the screwed state of the union nut 16.

Die Fig. 5 zeigt zwei Stecker für ein geschirmtes Über¬ gabesystem mit geradem Kabelausgang, der sich ergibt, wenn die Stirnwände 8,9 der Halbschalen 2,3 des Steckergehäuses 4 senkrecht zur Steckrichtung verlaufen. Es ist jedoch auch - insbesondere bei beengten Einbauverhältnissen - wie bei Fig. 6 ein abgewinkelter Kabelausgang möglich, wenn die Stirnwände zumindest teilweise schräg, z.B. in einem Winkel von 30°, zur Steckrichtung geneigt sind. 5 shows two plugs for a shielded transfer system with a straight cable outlet, which results when the end walls 8, 9 of the half-shells 2, 3 of the plug housing 4 run perpendicular to the plug-in direction. However, an angled cable outlet is also possible, particularly in the case of cramped installation conditions, as in FIG. are inclined at an angle of 30 ° to the direction of insertion.
