Description

Schraubenlose Steckverbindung Screwless connector
Die Erfindung bezieht sich auf einen Steckverbinder, der an ein Anschlußende mit frei beweglichen Adern eines Kabels anschließbar ist und mit einem Gegensteckverbinder gekoppelt werden kann, nach dem Oberbegriff des Anspruches 1. Der Steckverbinder folgt den Normen ICE 309-1, ICE 309-2 und EN 60 309 1 + 2 und ist für Kraftstrom gebaut.The invention relates to a connector that can be connected to a connection end with freely movable wires of a cable and can be coupled with a mating connector according to the preamble of claim 1. The connector follows the standards ICE 309-1, ICE 309-2 and EN 60 309 1 + 2 and is built for power current.
Derartige Steckverbinder sind aus den deutschen Gebrauchsmustern 297 07 710.4 und 297 07 711.2 begannt . Mit diesen werden Steckverbinder bereitgestellt, bei denen ein normgerechter Zusammenbau im Wesentlichen ohne den Einsatz von Schrauben gewährleistet wird. Die Zugentlastungseinrichtung ist jedoch so gestaltet, daß sie eine Knebelmutter beinhaltet und somit Schraubflächen aufweist. Der Erfindung liegt die Aufgabe zugrunde, einen total schraubenlosen Steckverbinder zu schaffen, bei dem die Zugentlastung im Gehäuse des Steckverbinders angeordnet ist. Die gestellte Aufgabe wird aufgrund der Merkmale des Anspruches 1 und des Anspruches 6 gelöst und durch die weiteren Merkmale der abhängigen Ansprüche ausgestaltet und weiterentwickelt . Der Steckverbinder, der als Stecker oder Kupplung (Dose) ausgebildet sein kann, weist ein erstes, im Wesentlichen rohrformiges Gehäuseteil aus isolierendem Kunststoff auf, das einen inneren, im wesentlichen zylindrischen Kontaktträger umfaßt. Das Anschlußende des Kabels, bei dem der Kabelmantel teilweise entfernt ist, um die isolierten Adern frei beweglich zu machen, kann mit diesen Adern, deren Enden freigelegt worden sind, durch ein zweites, im Wesentlichen rohrformiges Gehauseteil aus isolierendem Kunststoff gezogen werden, das mit dem ersten Gehauseteil verbindbar ist. Dieses weist eine Halteplatte auf, die zur Befestigung an dem ersten Gehauseteil vorgesehen ist, um Kontaktelemente m einem Kontakttrager des ersten Gehauseteiles zu halten. Die freien Aderenden werden in die Kontaktelemente gesteckt, welche schraubenlose Klemmeinrichtungen für die Enden der Adern aufweisen und diese festklemmen und danach werden erstes und zweites Gehauseteil durch Zusammenstecken und Drehen nach Art eines Bajonettverschlusses miteinander verbunden, wobei die Zugentlastungseinrichtung wirksam wird und das Kabel an seinem Mantel festklemmt. Zu diesem Zweck weist die Halteplatte oder ein mit ihr verbundenes Teil einen Kranz von Schragflachen an Nocken auf, die sich im kurzen Abstand zur Innenseite des zweiten Gehauseteiis und entlang dieser erstrecken. Die Zugentlastungseinrichtung umfaßt ein kafigartiges Klemmfutter, das einen Betatigungsπng mit daran angebrachten Schragflachen an Nocken aufweist, die mit dem Kranz der Schragflachen der Halteplatte zusammenarbeiten, wenn das erste und zweite Gehauseteil zusammengesteckt und gegeneinander gedreht werden. Das Klemmfutter umfaßt Klemmarme, die um das Anschlußende des Kabels herum verteilt angeordnet sind und eine Bogenkrummung zu dem Anschlußende hin sowie von diesem weg aufweisen, wobei jeweils ein radial innerer Scheitel gebildet wird, an dem Zahne oder Krallen angebracht sind, die sich im Kabelmantel festbeißen können. Die Klemmarme weisen freie Enden auf, die sich an Abstutzflachen des zweiten Gehauseteiis abstutzen, wenn das erste und das zweite Gehauseteil zusammengesteckt und verriegelt werden. Das kafigartige Klemmfutter wird also zwischen den beiden Gehauseteilen gestaucht, wodurch sich die radial inneren Scheitel der Klemmarme radial nach innen bewegen bis das Kabel dieser Bewegung ein Ende setzt, nachdem die Zähne oder Krallen der Klemmarme gegriffen haben. Je nach der Dicke des Kabels können die freien Enden der Klemmarme mehr oder weniger weit radial nach außen auf denSuch connectors are known from German utility models 297 07 710.4 and 297 07 711.2. These are used to provide connectors in which a standard-compliant assembly is essentially guaranteed without the use of screws. However, the strain relief device is designed so that it contains a toggle nut and thus has screw surfaces. The invention has for its object to provide a totally screwless connector, in which the strain relief is arranged in the housing of the connector. The stated object is achieved on the basis of the features of claim 1 and claim 6 and is designed and further developed by the further features of the dependent claims. The connector, which can be designed as a plug or coupling (socket), has a first, essentially tubular housing part made of insulating plastic, which comprises an inner, essentially cylindrical contact carrier. The connector end of the cable, with the cable jacket partially removed, free the insulated wires To make it movable, these wires, the ends of which have been exposed, can be pulled through a second, essentially tubular housing part made of insulating plastic, which can be connected to the first housing part. This has a holding plate which is provided for fastening to the first housing part in order to hold contact elements in a contact carrier of the first housing part. The free wire ends are inserted into the contact elements, which have screwless clamping devices for the ends of the wires and clamp them, and then the first and second housing parts are connected to one another by plugging and rotating in the manner of a bayonet lock, the strain relief device becoming effective and the cable on its jacket stuck. For this purpose, the holding plate or a part connected to it has a ring of inclined surfaces on cams which extend at a short distance from and along the inside of the second housing part. The strain relief device comprises a cage-like clamping chuck, which has a actuation with bevels attached to cams, which cooperate with the rim of the bevels of the holding plate when the first and second housing parts are plugged together and rotated against one another. The clamping chuck comprises clamping arms which are arranged distributed around the connection end of the cable and have an arcuate curvature towards and away from the connection end, in each case forming a radially inner apex on which teeth or claws are attached which bite into the cable sheath can. The clamping arms have free ends which are supported on the support surfaces of the second housing part when the first and second housing parts are plugged together and locked. The cage-like chuck is thus compressed between the two parts of the housing, whereby the Move the radially inner apex of the clamping arms radially inwards until the cable ends this movement after the teeth or claws of the clamping arms have gripped. Depending on the thickness of the cable, the free ends of the clamping arms can be more or less radially outward on the

Die Klemmplatte umgreift die Kontaktplatte mit einer Fensteröffnung, die einen Betätigungsrand (an der Kontaktplatte) und einen freien Rand (an der Bügelfeder) aufweist. Die Bügelfeder wirkt als Zugfeder auf die Klemmplatte und zieht den Betätigungsrand gegen die Kontaktplatte.

By moving the locking slide into the release position of the bow spring, the bow spring pulls the operating edge of the window opening against the inserted wire end and presses it against the contact plate of the respective contact element.
Der neue schraubenlose Steckverbinder hat den Vorteil, daß er ohne Werkzeug montiert werden kann. Durch das Prinzip der Klemmung sowohl der Aderenden als auch des Kabels erfolgt eine automatische Anpassung an den jeweiligen Querschnitt. Dies ermöglicht, ein und dieselben Steckverbinder für unterschiedlich bemessene flexible Leitungen bzw.

Eine schlaufenförmige Bügelfeder 8 weist zwei sich kreuzende Schenkel 9 und 10 auf, wobei der Schenkel 10 eine Fensteröffnung 11 besitzt, durch welche der Schenkel 9 hindurchreicht. Das Fenster umfaßt einen Betätigungsrand 12 und einen freien Rand 13. Durch Zusammendrücken derTo connect an exposed wire 41 of the cable 40, the contact elements 5 have a contact plate 7 (FIG. 2), which is integrally connected to the body of the contact element 5 together with a support leg 18. A loop-shaped bow spring 8 has two intersecting legs 9 and 10, the leg 10 having a window opening 11 through which the leg 9 extends. The window includes an operating edge 12 and a free edge 13. By compressing the
Bügelfeder 8 in Richtung auf den freien Rand hin läßt sich die Kontaktplatte 7 durch die Fensteröffnung schieben und durch Loslassen am Befestigungsrand 12 festklemmen und die Bügelfeder wird so von dem Kontaktelement 5 getragen.Bow spring 8 in the direction of the free edge, the contact plate 7 can be pushed through the window opening and clamped by releasing the fastening edge 12 and the Bow spring is carried by the contact element 5.
Wie aus Fig. 3 ersichtlich, reichen die Kontaktplatten 7 und die Bügelfedern 8 jeweils in einzelne Kammern 14 einer Halteplatte 15 hinein, die aus isolierendem Material besteht und mit dem Kontaktträger 4 verrastbar oder sonstwie verbindbar ist. Die Halteplatte 15 ist mit ersten Zugangsöffnungen 16 versehen, durch die sich jeweils ein Rastschieber 36 als Kontaktöffner erstreckt. Zweite Zugangsöffnungen 17 münden zu den Kontaktelementen im Bereich der Fenster 11. Der Rastschieber 36 weist eine Aussparung 37 auf, in welcher das bauchartig ausgebildete Verbindungsteil 8a der Bügelfeder 8 sitzt, wenn der Steckverbinder fertig montiert ist. Der Rastschieber 36 hat die Funktion eines Niederdrückwerkzeuges, das zwei Stellungen einnehmen kann, nämlich eine Freigabestellung, wie dargestellt, und eineAs can be seen from FIG. 3, the contact plates 7 and the bow springs 8 each extend into individual chambers 14 of a holding plate 15, which is made of insulating material and can be latched or otherwise connected to the contact carrier 4. The holding plate 15 is provided with first access openings 16, through each of which a locking slide 36 extends as a contact opener. Second access openings 17 open to the contact elements in the area of the windows 11. The locking slide 36 has a recess 37 in which the bell-shaped connecting part 8a of the bow spring 8 is seated when the plug connector is fully assembled. The locking slide 36 has the function of a depressing tool that can assume two positions, namely a release position, as shown, and one
Niederdrückstellung, bei der die Schrägfläche der Aussparung 37 den gebogenen Teil des Verbindungsschenkels 8a niederdrückt und das Fenster 11 öffnet, so daß das freie Aderende 41 in das Fenster 11 geschoben werden kann. Die beiden erwähnten Stellungen des Rastschiebers 36 werden durch Anschläge 38 und 39 bestimmt, die an jeweiligen Schultern der Halteplatte 15 anliegen. Um den Rastschieber 36 zwischen seinen beiden Öffnungen leicht verschieben zu können, ist eine Betätigungsöffnung 36a vorgesehen, an der man beispielsweise mittels eines Schraubendrehers den RastSchieber vor und zurück schieben kann.Depressed position, in which the inclined surface of the recess 37 presses down the bent part of the connecting leg 8a and opens the window 11 so that the free wire end 41 can be pushed into the window 11. The two mentioned positions of the locking slide 36 are determined by stops 38 and 39 which abut the respective shoulders of the holding plate 15. In order to be able to easily move the locking slide 36 between its two openings, an actuating opening 36a is provided, at which one can push the locking slide back and forth, for example by means of a screwdriver.
Um die Gehäuseteile 1 und 2 miteinander zu verbinden, ist ein schraubenloses Rastsystem 20 vorgesehen, das durch Ineinanderstecken und Drehen betätigbar ist und hierzu vier Riegelpaare 21 aufweist, die nach Art eines Bajonetts ineinander greifen und die Gehäuseteile 1 und 2 fest aufeinander pressen, so daß diese Teile wasserdicht gegeneinander verschlossen sind. Bei der Drehbewegung wird 7In order to connect the housing parts 1 and 2 to each other, a screwless locking system 20 is provided which can be actuated by inserting and rotating one into the other and for this purpose has four pairs of bolts 21 which engage in the manner of a bayonet and press the housing parts 1 and 2 firmly against one another, so that these parts are sealed watertight against each other. During the rotary movement 7
außerdem eine Zugentlastungseinrichtung 50 betätigt, die nachfolgend beschrieben wird.also operated a strain relief device 50, which will be described below.
Die Zugentlastungseinrichtung 50 umfaßt ein kafigartiges Klemmfutter 51, das zwischen Schragflachen 52 und gewölbten Abstützflachen 53 eingeklemmt wird. Die Schragflachen 52 werden durch einen Kranz von beispielsweise vier Nocken gebildet, der an der Halteplatte 15 angebracht ist und der sich im kurzen Abstand zu der Innenseite des zweiten Gehauseteils 2 und entlang dieser erstreckt. Die Abstutzflachen 53 sind umlaufend ausgebildet und stellen im Querschnitt ein Gewölbe dar.The strain relief device 50 comprises a cage-like clamping chuck 51 which is clamped between inclined surfaces 52 and curved support surfaces 53. The inclined surfaces 52 are formed by a ring of, for example, four cams, which is attached to the holding plate 15 and which extends at a short distance from and along the inside of the second housing part 2. The support surfaces 53 are formed all around and represent a vault in cross section.
Das käfigartige Klemmfutter 51 besitzt einen Betätigungsring 54, an dem Nocken zur Bildung von Schragflachen vorgesehen sind, die mit den Schragflachen 52 zusammen arbeiten. Der Betatigungsring 54 ist gegenThe cage-like clamping chuck 51 has an actuating ring 54 on which cams are provided to form inclined surfaces, which cooperate with the inclined surfaces 52. The actuation ring 54 is against
Verdrehung gesichert, indem eine oder mehrere Rippen 55 des Gehauseteils 2 in entsprechende Nuten im Betatigungsring 54 eingreift. Wenn demgemäß die Gehauseteile 1 und 2 durch Ineinanderstecken und Drehen miteinander verrastet werden, greifen die Schragflachen des Betatigungsringes 54 in die Schragflachen 52 der Halteplatte 15 ein, wodurch der Betatigungsring 54 in achsialer Richtung weg vom Gehauseteil 1 verschoben wird.Secured rotation by one or more ribs 55 of the housing part 2 engages in corresponding grooves in the actuating ring 54. Accordingly, when the housing parts 1 and 2 are locked together by inserting and rotating them, the inclined surfaces of the actuating ring 54 engage in the inclined surfaces 52 of the holding plate 15, whereby the actuating ring 54 is displaced in the axial direction away from the housing part 1.
Das käfigartige Klemmfutter 51 besitzt vier Klemmarme 56, die im Winkelabstand von 90° zueinander verteilt um das Kabel 40 herum angeordnet sind und die insgesamt S-formig gebogen sind. Dabei wird ein radial innerer Scheitel 57 gebildet, an welchem Zahne oder Krallen 58 sitzen. Die Arme 56 weisen freie Enden 59 auf, die sich an der gewölbten Flache 53 abstützen.The cage-like chuck 51 has four clamping arms 56, which are arranged at an angular distance of 90 ° from one another around the cable 40 and which are bent overall in an S-shape. A radially inner apex 57 is formed, on which teeth or claws 58 are seated. The arms 56 have free ends 59 which are supported on the curved surface 53.
An dem zweiten Gehauseteil 2 ist eine Schutztulle 60 angespritzt, die aus einem biegsamen Material besteht und Abdichtlippen 61 besitzt, die an dem Kabel 40 anliegen, um Feuchtigkeit und Staub vom Inneren des Gerätes fernzuhalten. Die Schutztülle dient auch dem Knickschutz des Kabels.A protective sleeve 60, which consists of a flexible material and has sealing lips 61, which bear against the cable 40, is injection molded onto the second housing part 2 Keep moisture and dust away from the inside of the device. The protective sleeve also serves to protect the cable from kinking.
Die Montage des Kabels an dem Steckverbinder wird wie folgt durchgeführt: Zuerst wird ein Stück des Mantels 42 des Kabels 40 entfernt, um einzelne isolierte Adern 43 zu gewinnen. Das vordere Ende dieser frei beweglichen isolierten Adern 43 wird abisoliert, um blanke Aderenden 41 zu gewinnen, über die gegebenenfalls noch Adernendhülsen geschoben werden. Das so vorbereitete Anschlußende des Kabels wird durch die an den Lippen 61 gebildete Öffnung in das Innere desThe assembly of the cable on the connector is carried out as follows: First, a piece of the jacket 42 of the cable 40 is removed in order to obtain individual insulated wires 43. The front end of these freely movable insulated wires 43 is stripped in order to obtain bare wire ends 41, over which wire end sleeves may also be pushed. The thus prepared connection end of the cable is through the opening formed on the lips 61 into the interior of the
Gehäuseteils 2 geschoben, bis die freien Aderenden 41 in Reichweite der Bügelfedern 8 gelangen. Der Rastschieber 36 wird in die Stellung zum Zusammendrücken der Bügelfeder 8 gebracht, sofern er nicht bereits in dieser Stellung angeliefert worden ist, in welcher das Fenster 11 geöffnet ist. Deshalb kann das Aderende 41 in das geöffnete Fenster 11 hineingeschoben werden, wobei es dann zwischen der Kontaktplatte 7 und dem Abstützschenkel 18 des Kontaktelements 5 anliegt. Durch Verschieben des Schiebers 36 in die dargestellte Freigabestellung wird dieHousing part 2 pushed until the free wire ends 41 reach the range of the bow springs 8. The locking slide 36 is brought into the position for compressing the bow spring 8, provided that it has not already been delivered in this position in which the window 11 is open. Therefore, the wire end 41 can be pushed into the open window 11, where it then lies between the contact plate 7 and the support leg 18 of the contact element 5. By moving the slide 36 in the release position shown, the
Zusammendrückung der Bügelfeder 8 aufgehoben und diese zieht das gefangene Aderende 41 fest gegen die Platte 7.Compression of the bow spring 8 is lifted and this pulls the captured wire end 41 firmly against the plate 7.
Nunmehr wird das Gehäuseteil 2 mit dem Gehäuseteil 1 verrastet, was durch achsiales Ineinanderstecken und Drehen erfolgt. Dabei kommen die Schrägflächen des Betätigungsringes 54 und die Schrägflächen 52 an der Halteplatte 15 zur Wirkung, d.h. das Klemmfutter 51 wird in achsialer Richtung relativ zu den Gehäuseteilen 1 und 2 in der Zeichnung nach oben gedrängt. Das freie Ende 59, das an der Abstützflache 53 anliegt, erlaubt jedoch keine reine Verschiebung desNow the housing part 2 is locked with the housing part 1, which is done by axially plugging and rotating. The inclined surfaces of the actuating ring 54 and the inclined surfaces 52 on the holding plate 15 come into effect, i.e. the chuck 51 is urged in the axial direction relative to the housing parts 1 and 2 in the drawing upwards. The free end 59, which rests on the support surface 53, however, does not allow a pure displacement of the
Klemmfutters 51. Dieses wird vielmehr gestaucht, wobei sich die Scheitel 57 der Klemmarme 56 radial nach innen bewegen. Bei dieser Bewegung graben sich die Zähne oder Krallen 58 in den Mantel 42 des Kabels ein, der daraufhin weiterer Bewegung der Klemmarme 56 einen solchen Widerstand entgegensetzt, daß die weitere Stauchung des Klemmfutters 51 zu einer Auswartskrümmung der Klemmarme im Bereich zwischen dem Scheitel 57 und dem Betatigungsring 54 führt. Diese Krümmung radial nach außen ist um so starker, je dicker das Kabel 40 ist, wie der Vergleich zwischen Fig. 1 und Fig. 3 zeigt.Clamping chuck 51. Rather, this is compressed, the apices 57 of the clamping arms 56 moving radially inwards. During this movement, the teeth or claws 58 dig in the jacket 42 of the cable, which then opposes further movement of the clamping arms 56 such a resistance that the further compression of the clamping chuck 51 leads to a forward curvature of the clamping arms in the area between the apex 57 and the actuating ring 54. This radially outward curvature is greater, the thicker the cable 40 is, as the comparison between FIGS. 1 and 3 shows.
Wenn an dem Kabel 40 gezogen wird, versuchen die Zahne 58 noch weiter in den Kabelmantel 42 einzudringen, so daß die Klemmung des Kabels 40 erhöht wird. Bei Schub auf das Kabel in Richtung des Gehauseinneren wird der Bewegung durch Verbiegen der Klemmarme 56 Widerstand entgegengesetzt, d.h. das Kabel ist auch in Einschubrichtung festgehalten. Das Gerat kann dadurch geöffnet werden, daß die Gehauseteile 1 und 2 entgegen ihrer Montagerichtung gedreht und dadurch entrastet werden. Dabei wird die Zugentlastung 50 entspannt und durch Zurückziehen des Gehauseteils 1 kann man bequemen Zugang ins Innere des Gehäuses erhalten. When the cable 40 is pulled, the teeth 58 attempt to penetrate further into the cable sheath 42, so that the clamping of the cable 40 is increased. If the cable is pushed towards the interior of the housing, the movement is resisted by bending the clamping arms 56, i.e. the cable is also held in the direction of insertion. The device can be opened by rotating the housing parts 1 and 2 against their mounting direction and thereby unlocking them. The strain relief 50 is relaxed and by pulling back the housing part 1 you can get easy access to the interior of the housing.
