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

Die Erfindung betrifft einen geschirmten Stecker mit einem Steckergehäuse, an dessen Kabeleinführseite ein geschirmtes Anschlußkabel mittels einer Kabelanschlußeinrichtung angeschlossen ist, die ein Crimpelement, eine über das Anschlußkabel schiebbare metallene Stützhülse und eine Überwurfmutter umfaßt, wobei die Stützhülse an einem Ende mit einem ein Außengewinde aufweisenden Gewindeteil zur Verschraubung mit der Überwurfmutter und am anderen Ende mit einem Kontaktteil für den Kabelschirm sowie zwischen dem Gewindeteil und dem Kontaktteil mit einem radial abstehenden Flansch ausgebildet ist, der Kabelschirm über das Kontaktteil umstülpt und mittels des Crimpelements fest gegen das Kontaktteil gedrückt ist und zur mechanischen Verbindung zwischen dem Steckergehäuse und der Kabelanschlußeinrichtung sowie zur Kontaktierung des Kabelschirmes mit dem Steckergehäuse die Stirnwand des Steckergehäuses zwischen dem Flansch der Stützhülse und der auf das Gewindeteil der Stützhülse aufgeschraubten Überwurfmutter fest eingespannt ist. Ein derartiger Stecker ist aus der EP-A-455 139 bekannt.The invention relates to a shielded plug with a connector housing, on the cable entry side of which a shielded connecting cable is connected by means of a cable connection device which comprises a crimping element, a metal supporting sleeve which can be pushed over the connecting cable and a union nut, the supporting sleeve at one end having a threaded part having an external thread is designed for screwing with the union nut and at the other end with a contact part for the cable shield and between the threaded part and the contact part with a radially projecting flange, the cable shield is turned over the contact part and is pressed firmly against the contact part by means of the crimping element and for the mechanical connection between the connector housing and the cable connection device and for contacting the cable shield with the connector housing, the end wall of the connector housing between the flange of the support sleeve and the on the threaded part of the Support sleeve screwed on union nut is firmly clamped. Such a plug is known from EP-A-455 139.

Durch DE-U- 87 13 046 ist ein geschirmter Stecker mit einem zweiteiligen Gehäuse und einer Kabelanschlußeinrichtung bekannt, die außer einer insbesondere als Knickschutz für das Kabel dienenden Tülle eine Doppelschelle umfaßt, wobei der eine Teil der Doppelschelle die Zugentlastung am Kabelmantel und der andere Teil die Kontaktierung des Kabelschirmes übernimmt. Die Doppelschelle ist auf den Kabelmantel und den Kabelschirm ausgerichtet, liegt auf einer Seite des Kabels auf und wird durch Festschrauben 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 zuverlässigen Zugentlastung zu stark gequetscht wird.From DE-U-87 13 046 a shielded connector with a two-part housing and a cable connection device is known which, in addition to a spout serving in particular as an anti-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 contacting the cable shield takes over. The double clamp is aligned with the cable sheath and the cable shield, lies on one side of the cable and is mechanically connected to the lower housing part by screwing, 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 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 halbkreisförmige Einführstutzenhälfte aufweisen. Mittels einer über den Einführstutzen und den Kabelschirm geschobenen Crimphülse, die mit einer Zange verformt wird, wird bei einem derartigen Stecker eine Schirmkontaktierung und gleichzeitig eine mechanische Verbindung der Gehäusehalbschalen im Bereich des Einführstutzens erreicht. Im zusammengesetzten Zustand bei verformter Crimphülse läßt sich dann das Steckergehäuse nicht mehr öffnen. Außerdem ist für die Verformung eine mit Einsätzen für unterschiedliche Durchmesser zu versehene relativ teuere Spezialzange erforderlich.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 crimp sleeve pushed over the insertion socket and the cable shield, which is deformed with pliers, shield contacting and at the same time a mechanical connection of the housing half-shells in the region of the insertion socket is achieved in 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 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 bei einem geschirmten Stecker der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß das Steckergehäuse aus zwei leitend ausgebildeten Teilen zusammengesetzt ist und die Teile des Steckergehäuses an der Kabeleinführseite jeweils mit einer Stirnwand und einer in dieser vorgesehenen, zum jeweils anderen Teil hin offenen Ausnehmung zur Einführung der Kabelanschlußeinrichtung ausgebildet sind und daß das Kontaktteil der Stützhülse spannzangenartig geschlitzt ist. Bei einem derartigen Stecker ist der Kabelanschluß mit einfachsten Werkzeugen in einem separaten Montageschritt und ergonomisch günstig in der Handhabung durchführbar, wobei bei geringstmöglicher Deformation des Kabelquerschnitts (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 die 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 öffnen. Schließlich ist bei einem derartigen Kabelanschluß auch der nachteilige Einfluß von Kalteinflußeigenschaften und Alterungserscheinungen bei Kunststoffen ausgeschlossen.This object is achieved in a shielded connector of the type mentioned according to the invention in that the connector housing is composed of two conductive parts and the parts of the connector housing on the cable entry side each with an end wall and one provided in this, to the other part open recess for the introduction of the cable connection device are formed and that the contact part of the support sleeve is slit like a collet. With such a plug, the cable connection can be carried out with the simplest tools in a separate assembly step and is ergonomically convenient to use, with a safe shield contacting with reliable mechanical strain relief being achieved with the least possible deformation of the cable cross section (circular shape). There the contact part of the support sleeve has slots and how a collet can be compressed until the slots 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. Finally, the disadvantageous influence of cold influence properties and signs of aging in plastics is also excluded with such a cable connection.

In vorteilhafter Weise ist bei einem erfindungsgemäßen Stekker das Kontaktteil der Stützhülse zumindest mit einigen Innengewindegängen versehen. Damit kann die Stützhülse mit leichter Vorspannung auf den Kabelmantel geschraubt werden, um einen definierten Sitz der Stützhülse zu gewährleisten.Advantageously, in a connector according to the invention, the contact part of the support sleeve is provided with at least some internal threads. This allows the support sleeve to be screwed onto the cable sheath with a slight pre-tension in order to ensure a defined fit of the support sleeve.

Im Hinblick auf die Verschraubung zwischen der Überwurfmutter 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 zumindest teilweise umgebender Kragen vorgesehen ist und wenn der Abstand zweier einander diametral gegenüberliegender Kragen im zusammengesetzten Zustand der Teile des Steckergehäuses kleiner ist als der Innendurchmesser der Überwurfmutter. In diesem Fall übergreift die aufgeschraubte Überwurfmutter die Stirnwand-Kragen und sichert den Zusammenhalt 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 connector 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 connector housing and if the distance two diametrically opposite collars 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 cohesion of the two parts of the connector housing.

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 Steckergehäuse 4 mit einem Steckereinsatz 5 und einer Kabelanschlußeinrichtung 6 für das Anschlußkabel 7. Die Halbschalen 2 und 3 des Steckergehäuses 4 sind zweckmäßigerweise 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 Ausnehmungen 10, 11 sind langlochartig in den zur Steckrichtung 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. 1 zeigt, ist in die eine Halbschale 3 der Steckereinsatz 5 mit dem über die Kabelanschlußeinrichtung 6 angeschlossenen Anschlußkabel 7 eingeführt, während die andere Halbschale 2 - wie die Fig. 2 zeigt - als Deckel den Stekker gechirmt abschließt.The connector 1 is - as shown in FIGS. 1 and 2 - from one of two conductive parts, for. B. 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, which each have an end wall 8 or 9 and a recess 10 or 11 provided in this and open to the other half-shell for the introduction of the cable connection device 6 are formed. 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 direction of insertion, and are each surrounded at their arcuate end by a collar 12 and 13 projecting perpendicularly to the respective end wall. As FIG. 1 shows, in one half-shell 3 the plug insert 5 with the connecting cable 7 connected via the cable connection device 6 is inserted, while the other half-shell 2 - as shown in FIG. 2 - closes the connector as a cover with a shield.

Die Kabelanschlußeinrichtung umfaßt - wie die Fig. 3 zeigt - ein ringförmiges Crimpelement 14, eine über das Anschlußkabel 7 schiebbare metallene Stützhülse 15 und eine relativ flache, ebenfalls metallene Überwurfmutter 16.The cable connection device comprises - as shown in FIG. 3 - an annular crimp element 14, a metal support sleeve 15 which can be pushed over the connection cable 7 and a relatively flat, also metal union nut 16.

Die Stützhülse 15 ist an einem Ende mit einem ein Außengewinde 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 - insbesondere wenn die Stützhülse aus einem sechskantigen Material hergestellt ist - eine Sechskant-Umfangsform 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.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 - especially if the support sleeve is made of a hexagonal material - has a hexagonal circumferential shape, the key width of the flange 22 being larger than the clear internal width - Here the width - of the recesses 10 and 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 gschraubt. Nun wird der Kabelschirm 20 über das Kontaktteil 19 umgestülpt, das ringförmige Crimpelement 14 darübergeschoben 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 Kontaktteil 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 Steckergehäuse 4 vorbereitet. Das derart mit der Kabelanschlußeinrichtung 6 vormontierte, in Fig. 4 dargestellte Anschlußkabel 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 zusammengesetzten 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 Kabelanschlußeinrichtung 6 hergestellt, wobei aufgrund einer entsprechenden lichten Außenweite der zwei einander diametral gegenüberliegenden Kragen 12, 13 die Überwurfmutter 16 diese Kragen übergreift. Außerdem ist im festgeschraubten Zustand der Überwurfmuter 16 die Kontaktierung des Kabelschirmes am Steckergehäuse 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 tensioned by means of simple 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 further penetrates into the cable sheath with its internal threads 21 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 connection cable 7 pre-assembled with the cable connection device 6, shown in FIG. 4, is now - as shown in FIG. 1 - inserted into the half-shell 3 of the plug housing 4 in such a way that the flange 22 of the support sleeve 15 is inside this half-shell, that is located under the end wall 9 thereof. After the half-shells 2 and 3 have been put 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 connector housing 4 and the cable connection device 6 is thus established, the union nut 16 engaging over these collars due to a corresponding clear outside width of the two diametrically opposite collars 12, 13. In addition, the contact of the cable shield on the connector housing 4 is made in the screwed state of the union nut 16.

Die Fig. 5 zeigt zwei Stecker für ein geschirmtes Übergabesystem 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 plugging direction. However, it is also possible - in particular in the case of cramped installation conditions - as in FIG. 6, if the end walls are at least partially inclined, for. B. are inclined at an angle of 30 ° to the direction of insertion.
