Definitions
- the invention relates to a plug-in device element such as a (power) socket with a plug-in collar. Furthermore, it relates to a method for locking such a plug-in device element.
- Electrical plug-in device elements as they are based, for example, the standard DIN EN 60309, have a circular cylindrical or sleeve-shaped plug collar, in which a radially outwardly pointing unmistakable groove is formed.
- the plug-in device element with the Unver Cauleysnut a socket (coupling), in which a complementary plug can be inserted.
- An on-plug located, radially outwardly facing guide nose must then lie when mating in the Unvercicanssnut, as can and plug fit only together. In this way, a wrong, "twisted” mating can be prevented in multi-pin plug devices.
- the WO 01/31750 A1 an electrical plug-in device with a plug and a coupling, wherein the plug collar of the coupling has a transverse to the insertion direction through opening. Through this passage opening the bracket of a padlock can be inserted to lock a connector connected to the connector in the inserted state.
- the plug has for this purpose on its outer side a circumferential groove which receives said bracket of the padlock.
- a printed circuit board connector which is anchored on a printed circuit board by means of rotatable locking bolts.
- the locking bolts carry an eccentrically mounted locking head, which can engage behind the circuit board.
- the mentioned "complementary" plug-in device elements have a nose or the like which has to traverse the space occupied by the locking section or the recess in the plug-in collar during the plugging operation. Then can be selectively blocked or released by a rotation of the locking pin about its longitudinal axis of the plug collar for the passage of the complementary plug-in device element. In particular, it can be prevented in the se way that an inserted complementary plug-in device element is unintentionally or unauthorized withdrawn. If the locking pin for the change between closed position and open position only has to be rotated about its longitudinal axis (and not additionally shifted), this has the advantage that its spatial position remains essentially the same.
- the longitudinal axis of the locking pin preferably extends through the interior of the plug collar or contacts it at least. In this way, the most compact design possible.
- the longitudinal axis of the locking pin is preferably transverse (i.e., not parallel) to the direction of insertion of the connector device element.
- the "plug-in direction” is understood to be the direction in which a complementary plug-in device element is moved when it is plugged into the plug-in collar.
- the longitudinal axis may extend at an angle of about 45 ° to 135 °, particularly preferably of about 90 ° to the insertion direction.
- the locking pin is mounted on two opposite sides of the recess and / or the Sperrabs chnittes. The pen is then stored safely against strong forces and protected against bending or breaking off.
- the locking pin in the general case can take on virtually any shape, it is preferably formed substantially cylindrical, wherein said longitudinal axis of rotation coincides with the cylinder axis. Particularly preferably, it is a circular cylindrical shape, which is rotationally symmetrical about the longitudinal axis.
- the recess and the locking portion of the locking pin are centered on different sides with respect to the longitudinal axis of the locking pin (ie on different sides of a plane containing the longitudinal axis). In this case, by a (180 °) rotation of the locking pin about its longitudinal axis, the recess and the locking portion to swap their position.
- a rotational movement of the locking pin can be achieved in various ways.
- the locking pin can project freely outwardly with one end, so that a user can grasp this end and turn the locking pin.
- engagement surfaces eg screwdriver slot, wrench surfaces, teeth, etc.
- the locking pin is verbu with a transverse (in particular perpendicular) extending to the longitudinal axis lever. About such a radially to the longitudinal axis of the lever can then be effected with relatively small forces rotation of the locking pin.
- the lever can either be formed integrally with the locking pin or preferably represent a separate component which engages in a transverse hole of the locking pin. By a screw thread on the lever and the transverse hole can be taken care of a positive, tight fit of the lever.
- the above-mentioned lever can engage according to an embodiment of the invention on one side of the locking pin in a pocket which limits the possibilities of movement of the lever.
- a previously mounted locking pin can be stored captive on the plug device element in this way.
- the locking pin is coupled to a spring element which biases him into a given rest position.
- the rest position can correspond in particular to the opening position, in which an unhindered mating (or separating) of two plug-in device elements is possible.
- the plug-in device element described above can optionally be developed so that the edge of the recess of the locking pin is in its rest position so inclined to the direction of insertion of the plug device element that a force acting on this edge in the insertion direction force can cause a rotation of the locking pin.
- This embodiment fixes the associated with component tolerances risk that the locking pin in its opening position still something in the plug collar protrude and could block it.
- the locking pin is in fact inclined so that a complementary plug device element when plugged together can push it aside if necessary.
- the plug-in collar of the plug-in device element is preferably provided with a Uncicleysnut. As already explained, this serves to receive the guide nose of an inserted complementary plug-in device element and thus to guarantee a correct angular position of the socket and plug.
- the locking portion or the recess of the locking pin preferably engage in the unmistakable groove, usually in an axially central region of the groove, so that the guide nose of a complementary plug device element which has already been fully inserted does not collide with the locking portion.
- the longitudinal axis of the locking pin preferably extends transversely to and / or through the unmistakable groove or at least touches it.
- the plug-in device element hereinafter referred to as a "sensor” (one or more parts) assembly, which is “activated” by a complementary plug-in device element, when the latter was (completely or at least partially) inserted into the plug-in device element.
- the "activation” of the sensor can in particular consist of a change in position (displacement, rotation, etc.) of the sensor, which can be exploited to recognize the inserted state.
- the said sensor may in particular be coupled to a locking mechanism which prevents movement of the locking pin when the sensor is not activated. In the activated state of the sensor, the movement of the locking pin is released accordingly.
- This embodiment makes sense in a latching pin biased to the open position. because it prevents unintentional inadvertent or improper locking of the plug collar.
- the senor can be coupled to a closing mechanism which can transfer the locking pin into the closed position or at least transfer it when the sensor is activated.
- a closing mechanism which can transfer the locking pin into the closed position or at least transfer it when the sensor is activated.
- an automatic locking can take place after the mating of two plug-in device elements.
- the embodiment described above is developed such that the locking mechanism can only transfer the locking pin (with the sensor activated) into the closed position when an electrical voltage is applied to the plug-in device element. In the de-energized state, therefore, no locking of the plug-in device is possible even when the sensor is activated, which makes sense, as a Verriegelu ng then safety is not necessary.
- the aforementioned voltage-sensitive closing mechanism may in particular include an electromagnet which is operated by voltage applied to the plug-in device element.
- the solenoid may cause the locking pin to rotate when connected to an existing voltage by activation of the sensor.
- the senor may also comprise at least one electrical contact component of the plug-in device element, ie a typically metallic part with a freely accessible (“contactable”) surface.
- An “activation” of the sensor can then take place in that the contact component (mechanical and in particular electrical) gets contact with an electrically conductive component of an inserted complementary plug-in device element.
- the contact component mechanical and in particular electrical
- an electrically conductive component of an inserted complementary plug-in device element for example, could be provided in an outlet two spaced plug-in contact components between which upon insertion of a plug an electrical connection is made, closed by a circuit and a desired effect is triggered.
- contact devices plugets, plug pins
- plug-and-socket devices they can advantageously be used simultaneously for the realization of the sensor in the described embodiment.
- those of the "normal" contact components are used for the realization of the sensor, which are touched as the last (towards the end of the mating process) of its counter-contact.
- the locking pin is designed so that it can exert on a plugged into the plug collar, complementary plug device element a force acting in (or opposite) the plugging direction.
- the locking portion like the tooth of a gear, may press on a complementary male member to move it in the insertion direction.
- An active support of the insertion process can in particular ensure that the electrical contact components get in the plug-in device egg nen sufficient overlap for a secure power transmission.
- the locking pin can optionally be designed so that it can be manually rotated by a user about its longitudinal axis.
- the plug-in device element may also include an active drive, which can move the locking pin from the open position to the closed position and / or vice versa from the closed position to the open position.
- the energy for this drive can be taken in particular of the plug-in device element usually applied voltage.
- the active drive of the locking pin has z. B. the advantage that the lock can be done automatically, which is comfortable and prevents accidental forgetting.
- the drive can also be used for this purpose ensure that a force is actively exerted in (or against) the direction of insertion on a complementary plug-in device element, in order to convert this into an electrically safe plug state.
- the mentioned active drive may optionally include an end position sensor, which detects the reaching of a predefined end position of the locking pin. In this way it can be verified that the locking pin is in a desired target position - for example, the closed position - is. Furthermore, the detection of the end position can be used to control the drive and to change it, for example, from a control operation to a (energy-saving) holding operation.
- the invention relates to a plug-in device element with a plug-in sleeve, which has a notch on its outer side.
- This notch is preferably geometrically designed so that it can accommodate a transverse to the direction of insertion cylindrical body.
- the notch may be formed as a circumferential groove around the socket.
- the plug-in device element is a plug, but in principle it can also be a can / coupling.
- the described plug-in device element can in particular be used together with a plug-in device element according to the first aspect of the invention.

- the invention further relates to a method for locking the plug-in collar of a plug-in device element, in particular a plug-in device element of the type described above.
- the method is characterized in that a locking pin is rotated about its longitudinal axis, whereby optionally a recess or a locking portion of the locking pin come to rest in the plug collar.
- the method generally corresponds to the operation of the above-described plug-in device element, so that reference may be made to the description given there for the explanation of its details and advantages.
- the locking mechanism according to the invention is located on the plug-in socket 100 or a coupling of a force plug-in device. It should be noted, however, that in principle it could also be formed on a plug.
- Steckvoriquessdose 100 has in a known manner a circular cylindrical plug collar 101, which surrounds a bushing insert 103 (shown dotted in the sectional views) to form an annular gap.
- the socket insert 103 contains the usual electrical devices, such as contact sockets for various phases, conductor terminals, etc. in a manner which is of no further interest here.
- FIG. 3 shows in this regard a complementary plug 200 (in the FIGS. 3 and 4 shown with black cut surfaces and otherwise cross-hatched), in which a cylindrical plug-in sleeve 201, the current-carrying connector pins (not shown) protectively surrounds.
- said plug-in sleeve 201 fits exactly into the annular gap in the plug-in collar 101.
- a guide nose 202 located radially outward at the front end of the plug-in sleeve 201 must be received by the uniqueness groove 102 so that the plug-in process is in the correct relative angular position of the can 100 and plug 200 can be done.
- a locking pin 10 is provided according to the invention, which is designed substantially as an elongated circular cylinder and rotatably in a cylindrical bearing sleeve 20 of the socket housing about its longitudinal axis D ( FIG. 2 ) is housed.
- the locking pin 10 extends transversely through the unmistakable groove 102, at an axially approximately central position of this groove.
- the locking pin 10 has a recess 12, wherein the recess opposite material of the locking pin corresponding to a so-called "lock portion" 11 forms ( FIG. 7 ).
- a torsion spring 22 can be seen, which biases the locking pin in a certain rest position.
- this rest position corresponds to in FIG. 1 shown opening position PP.
- the recess 12 In this opening position ⁇ P the recess 12 is in the Unver Caullleysnut 102 so that a guide nose can pass freely through this groove.
- the locking pin is preferably positioned with the edge of the recess 12 slightly obliquely to the axis of the unmistakable groove 102, so that he even in unavoidable component and dimensional tolerances in no case hinrag in the near-open area in the Unvercicleysnut, which could inadvertently block a guide lug.
- FIG. 1 upper (opening away) end of the locking portion 11 in the unmistakable groove 102 only the in FIG. 1 upper (opening away) end of the locking portion 11 in the unmistakable groove 102 in, but this does not bother, since it can be easily pushed aside by a guide lug during insertion.
- FIG. 3 shows a state in which a plug 200 is inserted by movement in the direction of insertion S about halfway into the can 100.
- the above-mentioned state is recognizable that the guide lug 202, if necessary, pushes aside an optionally in the way blocking portion 11 aside.
- FIG. 4 shows the socket 100 after the plug 200 has been fully inserted.
- the guide lug 202 has moved through the unmistakable groove 102 to behind the locking pin 10.
- the locking pin 10 has been rotated after passing through the guide nose 202 in its "closed position" SP, in which the locking portion 11 protrudes into the unmistakable groove 102.
- the locking portion 11 protrudes into the guide groove 102 at the opening remote side, so that a retraction of the plug 200, the locking pin 10 (unlike plugging) could not push aside.
- the bearing of the locking pin 10 on both sides of the unmistakable groove 102 ensures high stability even in the event that high forces are exerted on the locking pin 10 by retracting the plug 200 (improperly).
- FIGS. 5 and 6 show the corresponding exterior views FIG. 3 (half plug 200) or FIG. 4 (completely plugged in 200). It can be seen in particular, as the movement of the locking pin 10 between the open position ⁇ P and closing position SP, ie the rotation of the locking pin 10 about its longitudinal axis D.
- the lever 13 is realized by a threaded pin, which is guided in a through hole with internal thread in the locking pin 10. That in the FIGS. 5 and 6 right end of the lever 13 engages in a pocket 21 of the bearing 20 (the front surface of the pocket 21 is not visible due to the sectional view).
- the pocket 21 prevents axial displacement of the locking pin 10 and limits its rotatability to a certain angular range.
- the locking pin 10 When the solenoid 110 is de-energized, the locking pin 10 is rotated under the action of the spring 22 in a clockwise direction in the opening position ⁇ P and the plunger 112 is raised ( FIG. 5 ). In the de-energized state of the plug-in device thus no locking takes place, and the opening position ⁇ P is simultaneously determined by the spring tension as the rest position.
- the switching on of the electromagnet 110 takes place in the illustrated embodiment via a sensor 111, which is attached to the bottom of the unmistakable groove 102.
- the sensor 111 is displaced from the guide nose 202, whereby a switch (not shown) is closed and the solenoid 110 can be energized.
- the solenoid 110 then brings the locking pin 10 in the closed position SP and ensures a locking of the plug-in device.
- the entire plug-in device must either be de-energized (the locking pin 10 then assumes by the action of the spring 22 its rest position, ie the opening position ⁇ P), or the locking pin 10 must be manually rotated by a user back to the open position ,
- suitable mechanical actuating means such as a rotary handle, which is not shown in detail in the figures.
- the described function of the sensor 111 could also be fulfilled by at least one of the electrical contact components of the plug-in device element.
- this could be the contact socket of the socket 100th be the last with an associated contact pin of the plug 200 gets electrical contact. Since a sensor realized in this way is activated directly at the first contact of the contact components, but on the other hand a certain minimum overlap of the electrical contacts is desirable for a safe current transmission, the above-mentioned active support of the insertion is additionally preferred. This means that after the first electrical contact of the sensor, an automatic, active support of the insertion process takes place until the desired minimum overlap is established.
- the socket 100 has a plug-in collar 101 with a Unvercicleysnut 102, in which engages the guide nose 202 of the complementary plug 200.
- the show FIGS. 8 to 10 three embodiments of connectors, which instead of a guide nose (at least) have a notch into which a locking pin can engage. The matching with these plugs outlet with such a locking pin results readily by appropriate modification of the circular cylindrical socket 100 from the FIGS. 1 to 6 and is not shown here.
- FIG. 8 shows as a first embodiment of a connector 1200 in which electrical contact pins 1210 are housed in a socket 1201.
- the triangular shape of the receptacle 1201 ensures that the plug 1200 can only be assembled in a single (correct) angular position with a complementary box.
- one of the three edges extending in the plug-in direction S has a notch 1202 in the front region (ie near the opening of the plug-in sleeve 1201).
- this notch 1202 the locking pin 10 (FIG. FIG. 7 ) of a complementary socket to lock the plug 1200 in the inserted state.
- FIG. 9 shows a modification in the form of a plug 2200, in which the triangular receptacle 2201 has notches 2202 on all three edges.
- This embodiment can thus provide up to three separate locking pins for a particularly secure locking of the inserted state. If an actively supported plugging (or separating) is provided by a drive of the locking pins, this can be done correspondingly more uniformly when using a plurality of locking pins.
- FIG. 10 shows a plug 3200, in which the triangular plug-in collar 3201 has a notch in the form of a circumferential groove 3202.
- one or more locking pins engage not only at the edges, but along the entire straight extension of a groove portion and thus ensure a particularly strong locking (or vigorous active movement of the plug).
- FIGS. 8 to 10 Illustrated use of notches on a socket can of course be provided in other forms of the socket, for example in rotationally symmetric receptacles.

Description
Die Erfindung betrifft ein Steckvorrichtungselement wie beispielsweise eine (Kraft-)Steckdose mit einem Steckkragen. Ferner betrifft sie ein Verfahren zur Verriegelung eines solchen Steckvorrichtungselementes.The invention relates to a plug-in device element such as a (power) socket with a plug-in collar. Furthermore, it relates to a method for locking such a plug-in device element.
Elektrische Steckvorrichtungselemente, wie sie beispielsweise der Norm DIN EN 60309 zugrunde liegen, weisen einen kreiszylindrischen bzw. hülsenförmigen Steckkragen auf, in dem eine radial nach außen weisende Unverwechselbarkeitsnut ausgebildet ist. Nachfolgend wird von dem in der Praxis üblichen Fall ausgegangen, dass das Steckvorrichtungselement mit der Unverwechselbarkeitsnut eine Steckdose (Kupplung) ist, in die ein komplementärer Stecker eingesteckt werden kann. Eine am Stecker befindliche, radial nach außen weisende Führungsnase muss dann beim Zusammenstecken in der Unverwechselbarkeitsnut liegen, da Dose und Stecker nur so zusammen passen. Auf diese Weise kann bei mehrpoligen Steckvorrichtungen ein falsches, "verdrehtes" Zusammenstecken verhindert werden.Electrical plug-in device elements, as they are based, for example, the standard DIN EN 60309, have a circular cylindrical or sleeve-shaped plug collar, in which a radially outwardly pointing unmistakable groove is formed. Below is assumed from the usual practice in the case that the plug-in device element with the Unverwechselbarkeitsnut a socket (coupling), in which a complementary plug can be inserted. An on-plug located, radially outwardly facing guide nose must then lie when mating in the Unverwechselbarkeitsnut, as can and plug fit only together. In this way, a wrong, "twisted" mating can be prevented in multi-pin plug devices.

Vor diesem Hintergrund war es Aufgabe der vorliegenden Erfindung, Steckvorrichtungen bereitzustellen, welche im zusammengesteckten Zustand gegen ein ungewolltes Trennen gesichert werden können.Against this background, it was an object of the present invention to provide plugs, which can be secured against accidental disconnection in the assembled state.
Diese Aufgabe wird durch ein Steckvorrichtungselement nach Anspruch 1 bzw. 13, durch eine Steckvorrichtung nach Anspruch 14, sowie durch ein Verfahren nach Anspruch 15 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.This object is achieved by a plug-in device element according to
Gemäß einem ersten Aspekt der Erfindung umfasst das erfindungsgemäße Steckvorrichtungselement, welches typischerweise eine Steckdose oder Kupplung ist (aber im Prinzip auch ein Stecker sein kann), neben den üblichen, elektrischen Bauteilen eines Steckvorrichtungselementes (Kontakte, Leiteranschlüsse etc.) die folgenden Komponenten:
- a) Einen Steckkragen. Dieser ist typischerweise hülsenförmig ausgebildet und umgibt schützend elektrische Bauteile.
- b) Einen Verriegelungsstift, der derart um eine körpereigene Längsachse drehbar am Steckvorrichtungselement gelagert ist, dass
- b1) in einer "Schließposition" des Verriegelungsstiftes ein Sperrabschnitt des Verriegelungsstiftes in den Steckkragen eingreift (d. h. in den Innenraum des Steckkragens), um das Passieren eines komplementären Steckvorrichtungselementes zu blockieren,
- b2) oder alternativ in einer "Öffnungsposition" des Verriegelungsstiftes eine Ausnehmung des Verriegelungsstiftes in dem Steckkragen liegt und Letzteren somit für die Passage eines komplementären Steckvorrichtungselementes freigibt.
- a) A plug collar. This is typically sleeve-shaped and surrounds protective electrical components.
- b) a locking pin which is mounted so as to be rotatable about a body's own longitudinal axis on the plug-in device element, that
- b1) in a "closed position" of the locking pin engages a locking portion of the locking pin in the plug collar (ie in the interior of the plug collar) to block the passage of a complementary plug-in device element,
- b2) or alternatively in a "open position" of the locking pin is a recess of the locking pin in the plug collar and thus releases the latter for the passage of a complementary plug device element.
Die erwähnten "komplementären" Steckvorrichtungselemente weisen eine Nase oder dergleichen auf, die beim Steckvorgang den vom Sperrabschnitt bzw. der Ausnehmung im Steckkragen eingenommenen Raum durchqueren muss. Dann kann durch eine Drehung des Verriegelungsstiftes um seine Längsachse der Steckkragen für das Passieren des komplementären Steckvorrichtungselementes wahlweise blockiert oder freigegeben werden. Insbesondere kann auf die se Weise verhindert werden, dass ein eingestecktes komplementäres Steckvorrichtungselement unbeabsichtigt oder unautorisiert abgezogen wird. Wenn der Verriegelungsstift für den Wechsel zwischen Schließposition und Öffnungsposition ausschließlich um seine Längsachse gedreht (und nicht zusätzlich noch verschoben) werden muss, hat dies den Vorteil, dass seine räumliche Lage im Wesentlichen gleich bleibt. Bei einem rotationssymmetrisch um die Längsachse ausgebildeten Verriegelungsstift ändert sich der vom Stift eingenommene Raum sogar überhaupt nicht. Dies minimiert den Platzbedarf für den Verriegelungs stift und ermöglicht andererseits eine robuste, stabile Lagerung im Gehäuse des Steckvorrichtungselementes.The mentioned "complementary" plug-in device elements have a nose or the like which has to traverse the space occupied by the locking section or the recess in the plug-in collar during the plugging operation. Then can be selectively blocked or released by a rotation of the locking pin about its longitudinal axis of the plug collar for the passage of the complementary plug-in device element. In particular, it can be prevented in the se way that an inserted complementary plug-in device element is unintentionally or unauthorized withdrawn. If the locking pin for the change between closed position and open position only has to be rotated about its longitudinal axis (and not additionally shifted), this has the advantage that its spatial position remains essentially the same. In a rotationally symmetric about the longitudinal axis even if the lock pin is formed, the space occupied by the pin does not change at all. This minimizes the space required for the locking pin and on the other hand allows a robust, stable storage in the housing of the connector element.
Die Längsachse des Verriegelungsstiftes verläuft vorzugsweise durch den Innenraum des Steckkragens oder berührt diesen zumindest. Auf diese Weise wird eine möglichst kompakte Bauweise erreicht.The longitudinal axis of the locking pin preferably extends through the interior of the plug collar or contacts it at least. In this way, the most compact design possible.
Des Weiteren verläuft die Längsachse des Verriegelungsstiftes vorzugsweise quer (d. h. nicht parallel) zur Steckrichtung des Steckvorrichtungselementes. In diesem Zusammenhang wird unter der "Steckrichtung" diejenige Richtung verstanden, in die ein komplementäres Steckvorrichtungselement bewegt wird, wenn es in den Steckkragen eingesteckt wird. Insbesondere kann die Längsachse in einem Winkel von ca. 45° bis 135°, besonders bevorzugt von ca. 90° zur Steckrichtung verlaufen.Furthermore, the longitudinal axis of the locking pin is preferably transverse (i.e., not parallel) to the direction of insertion of the connector device element. In this context, the "plug-in direction" is understood to be the direction in which a complementary plug-in device element is moved when it is plugged into the plug-in collar. In particular, the longitudinal axis may extend at an angle of about 45 ° to 135 °, particularly preferably of about 90 ° to the insertion direction.
Des Weiteren ist es von Vorteil, wenn der Verriegelungsstift auf zwei gegenüberliegenden Seiten der Ausnehmung und/oder des Sperrabs chnittes gelagert ist. Der Stift ist dann auch gegenüber starken Krafteinwirkungen sicher gelagert und vor einem Verbiegen oder Abbrechen geschützt.Furthermore, it is advantageous if the locking pin is mounted on two opposite sides of the recess and / or the Sperrabs chnittes. The pen is then stored safely against strong forces and protected against bending or breaking off.
Während der Verriegelungsstift im allgemeinen Fall quasi jede beliebige Form annehmen kann, ist er vorzugsweise im Wesentlichen zylinderförmig ausgebildet, wobei die erwähnte Längsachse der Drehung mit der Zylinderachse zusammenfällt. Besonders bevorzugt handelt es sich um eine kreiszylindrische Form, welche rotationssymmetrisch um die Längsachse ist.While the locking pin in the general case can take on virtually any shape, it is preferably formed substantially cylindrical, wherein said longitudinal axis of rotation coincides with the cylinder axis. Particularly preferably, it is a circular cylindrical shape, which is rotationally symmetrical about the longitudinal axis.
Bei einer bevorzugten Ausführungsform liegen die Ausnehmung und der Sperrabschnitt des Verriegelungsstiftes schwerpunktmäßig auf verschiedenen Seiten in Bezug auf die Längsachse des Verriegelungsstiftes (d. h. auf verschiedenen Seiten einer die Längsachse enthaltenden Ebene). In diesem Falle können durch eine (180°-) Drehung des Verriegelungsstiftes um seine Längsachse die Ausnehmung und der Sperrabschnitt ihre Position vertauschen.In a preferred embodiment, the recess and the locking portion of the locking pin are centered on different sides with respect to the longitudinal axis of the locking pin (ie on different sides of a plane containing the longitudinal axis). In this case, by a (180 °) rotation of the locking pin about its longitudinal axis, the recess and the locking portion to swap their position.
Eine Drehbewegung des Verriegelungsstiftes kann auf verschiedene Arten erreicht werden. Beispielsweise kann der Verriegelungsstift mit einem Ende frei zugänglich nach außen ragen, so dass ein Benutzer dieses Ende fassen und den Verriegelungsstift drehen kann. Des Weiteren können am Verriegelungsstift Angriffsflächen (z. B. Schraubendreherschlitz, Schlüsselflächen, Zähne etc.) ausgebildet sein, an welchen andere Bauteile ansetzen können. Bei einer bevorzugten Ausführungsform ist der Verriegelungsstift mit einem quer (insbesondere senkrecht) zur Längsachse verlaufenden Hebel verbu nden. Über einen solchen radial zur Längsachse liegenden Hebel kann dann mit verhältnismäßig geringen Kräften eine Drehung des Verriegelungsstiftes bewirkt werden. Der Hebel kann dabei entweder einstückig mit dem Verriegelungsstift ausgebildet sein oder aber vorzugsweise ein separates Bauteil darstellen, welches in ein Querloch des Verriegelungsstiftes eingreift. Durch ein Schraubengewinde an Hebel und Querloch kann dabei für einen formschlüssigen, festen Sitz des Hebels gesorgt werden.A rotational movement of the locking pin can be achieved in various ways. For example, the locking pin can project freely outwardly with one end, so that a user can grasp this end and turn the locking pin. Furthermore, engagement surfaces (eg screwdriver slot, wrench surfaces, teeth, etc.) may be formed on the locking pin, to which other components can attach. In a preferred embodiment, the locking pin is verbu with a transverse (in particular perpendicular) extending to the longitudinal axis lever. About such a radially to the longitudinal axis of the lever can then be effected with relatively small forces rotation of the locking pin. The lever can either be formed integrally with the locking pin or preferably represent a separate component which engages in a transverse hole of the locking pin. By a screw thread on the lever and the transverse hole can be taken care of a positive, tight fit of the lever.
Der vorstehend erwähnte Hebel kann gemäß einer Weiterbildung der Erfindung auf einer Seite des Verriegelungsstiftes in eine Tasche eingreifen, welche die Bewegungsmöglichkeiten des Hebels begrenzt. Bei einem nachträglich eingesetzten Hebel kann auf diese Weise auch ein zuvor montierter Verriegelungsstift verliersicher am Steckvorrichtungselement gelagert werden.The above-mentioned lever can engage according to an embodiment of the invention on one side of the locking pin in a pocket which limits the possibilities of movement of the lever. In a subsequently used lever, a previously mounted locking pin can be stored captive on the plug device element in this way.
Gemäß einer anderen Weiterbildung der Erfindung ist der Verriegelungsstift mit einem Federelement gekoppelt, welches ihn in eine gegebene Ruhestellung vorspannt. Die Ruhestellung kann dabei insbesondere der Öffnungsposition entsprechen, in welcher ein ungehindertes Zusammenstecken (oder Trennen) von zwei Steckvorrichtungselementen möglich ist.According to another embodiment of the invention, the locking pin is coupled to a spring element which biases him into a given rest position. The rest position can correspond in particular to the opening position, in which an unhindered mating (or separating) of two plug-in device elements is possible.
Das vorstehend beschriebene Steckvorrichtungselement kann optional so weitergebildet werden, dass der Rand der Aussparung des Verriegelungs stiftes in dessen Ruhestellung derart geneigt zur Steckrichtung des Steckvorrichtungselementes steht, dass eine auf diesen Rand in Steckrichtung einwirkende Kraft eine Drehung des Verriegelungsstiftes bewirken kann. Diese Ausführungsform behebt die mit Bauteiltoleranzen verbundene Gefahr, dass der Verriegelungs stift in seiner Öffnungsposition doch noch etwas in den Steckkragen hineinragen und diesen blockieren könnte. Der Verriegelungsstift wird nämlich derart schräg gestellt, dass ihn ein komplementäres Steckvorrichtungselement beim Zusammenstecken nötigenfalls beiseite schieben kann.The plug-in device element described above can optionally be developed so that the edge of the recess of the locking pin is in its rest position so inclined to the direction of insertion of the plug device element that a force acting on this edge in the insertion direction force can cause a rotation of the locking pin. This embodiment fixes the associated with component tolerances risk that the locking pin in its opening position still something in the plug collar protrude and could block it. The locking pin is in fact inclined so that a complementary plug device element when plugged together can push it aside if necessary.
Der Steckkragen des Steckvorrichtungselementes ist vorzugsweise mit einer Unverwechselbarkeitsnut versehen. Wie bereits erläutert dient diese dazu, die Führungsnase eines eingesteckten komplementären Steckvorrichtungselementes aufzunehmen und so eine korrekte Winkelstellung von Dose und Stecker zu garantieren. Bei dieser Ausführungsform greifen der Sperrabschnitt bzw. die Ausnehmung des Verriegelungsstiftes vorzugsweise in die Unverwechselbarkeitsnut ein, und zwar in der Regel in einem axial mittleren Bereich der Nut, so dass die Führungsnase eines bereits ganz eingesteckten komplementären Steckvorrichtungselementes nicht mit dem Sperrabschnitt kollidiert. Weiterhin verläuft die Längsachse des Verriegelungsstiftes vorzugsweise quer zu und/oder durch die Unverwechselbarkeitsnut oder berührt diese zumindest.The plug-in collar of the plug-in device element is preferably provided with a Unwechselbarkeitsnut. As already explained, this serves to receive the guide nose of an inserted complementary plug-in device element and thus to guarantee a correct angular position of the socket and plug. In this embodiment, the locking portion or the recess of the locking pin preferably engage in the unmistakable groove, usually in an axially central region of the groove, so that the guide nose of a complementary plug device element which has already been fully inserted does not collide with the locking portion. Furthermore, the longitudinal axis of the locking pin preferably extends transversely to and / or through the unmistakable groove or at least touches it.
Gemäß einer anderen Weiterbildung der Erfindung weist das Steckvorrichtungselement eine nachfolgend als "Fühler" bezeichnete (ein- oder mehrteilige) Baugruppe auf, welche von einem komplementären Steckvorrichtungselement "aktiviert" wird, wenn Letzteres (ganz oder zumindest teilweise) in das Steckvorrichtungselement eingesteckt wurde. Die "Aktivierung" des Fühlers kann insbesondere in einer Lageveränderung (Verschiebung, Drehung etc.) des Fühlers bestehen, welche dazu ausgenutzt werden kann, den eingesteckten Zustand zu erkennen.According to another embodiment of the invention, the plug-in device element hereinafter referred to as a "sensor" (one or more parts) assembly, which is "activated" by a complementary plug-in device element, when the latter was (completely or at least partially) inserted into the plug-in device element. The "activation" of the sensor can in particular consist of a change in position (displacement, rotation, etc.) of the sensor, which can be exploited to recognize the inserted state.
Der genannte Fühler kann insbesondere mit einem Sperrmechanismus gekoppelt sein, welcher eine Bewegung des Verriegelungsstiftes verhindert, wenn der Fühler nicht aktiviert ist. Im aktivierten Zustand des Fühlers ist die Bewegung des Verriegelungsstiftes dementsprechend freigegeben. Diese Ausführungsform macht bei einem in die Öffnungsposition vorgespannten Verriegelungsstift Sinn, da sie im ungesteckten Zustand ein unbeabsichtigtes oder missbräuchliches Verriegeln des Steckkragens verhindert.The said sensor may in particular be coupled to a locking mechanism which prevents movement of the locking pin when the sensor is not activated. In the activated state of the sensor, the movement of the locking pin is released accordingly. This embodiment makes sense in a latching pin biased to the open position. because it prevents unintentional inadvertent or improper locking of the plug collar.
Alternativ oder zusätzlich kann der Fühler mit einem Schließmechanismus gekoppelt sein, welcher den Verriegelungsstift in die Schließposition überführt bzw. zumindest überführen kann, wenn der Fühler aktiviert ist. Bei dieser Ausführungsform kann ein automatisches Verriegeln nach dem Zusammenstecken zweier Steckvorrichtungselemente erfolgen.Alternatively or additionally, the sensor can be coupled to a closing mechanism which can transfer the locking pin into the closed position or at least transfer it when the sensor is activated. In this embodiment, an automatic locking can take place after the mating of two plug-in device elements.
Vorzugsweise wird die vorstehend beschriebene Ausführungsform so weitergebildet, dass der Schließmechanismus den Verriegelungsstift (bei aktiviertem Fühler) nur dann in die Schließposition überführen kann, wenn an dem Steckvorrichtungselement eine elektrische Spannung anliegt. Im stromlosen Zustand ist demnach auch bei aktiviertem Fühler keine Verriegelung der Steckvorrichtung möglich, was sinnvoll ist, da eine Verriegelu ng dann sicherheitstechnisch auch nicht nötig ist.Preferably, the embodiment described above is developed such that the locking mechanism can only transfer the locking pin (with the sensor activated) into the closed position when an electrical voltage is applied to the plug-in device element. In the de-energized state, therefore, no locking of the plug-in device is possible even when the sensor is activated, which makes sense, as a Verriegelu ng then safety is not necessary.
Der vorstehend erwähnte spannungssensitive Schließmechanismus kann insbesondere einen Elektromagneten enthalten, der von am Steckvorrichtungselement anliegender Spannung betrieben wird. Der Elektromagnet kann beispielsweise eine Drehung des Verriegelungsstiftes bewirken, wenn er durch Aktivierung des Fühlers an eine vorhandene Spannung angeschlossen wird.The aforementioned voltage-sensitive closing mechanism may in particular include an electromagnet which is operated by voltage applied to the plug-in device element. For example, the solenoid may cause the locking pin to rotate when connected to an existing voltage by activation of the sensor.
Gemäß einer anderen Ausführungsform der Erfindung kann der Fühler auch mindestens ein elektrisches Kontaktbauteil des Steckvorrichtungselementes umfassen, d. h. ein typischerweise metallisches Teil mit einer frei zugänglichen ("kontaktierbaren") Fläche. Eine "Aktivierung" des Fühlers kann dann dadurch erfolgen, dass das Kontaktbauteil (mechanischen und insbesondere elektrischen) Kontakt zu einem elektrisch leitfähigen Bauteil eines eingesteckten komplementären Steckvorrichtungselementes bekommt. Beispielsweise könnten in einer Steckdose zwei in Steckrichtung beabstandete Kontaktbauteile vorgesehen sein, zwischen denen bei Einführen eines Steckers eine elektrische Verbindung hergestellt wird, durch die ein Stromkreis geschlossen und ein gewünschter Effekt ausgelöst wird. Durch die Verwendung elektrischer Kontaktbauteile kann die Fühlerfunktion ohne bewegliche Teile und damit besonders robust ausgebildet werden. Da in Steckvorrichtungen im Übrigen immer schon Kontaktbauteile (Buchsen, Steckerstifte) vorhanden sind, können diese bei der beschriebenen Ausführungsform vorteilhafterweise gleichzeitig zur Realisierung des Fühlers verwendet werden. In diesem Falle ist es bevorzugt, wenn von den "normalen" Kontaktbauteilen solche für die Realisierung des Fühlers eingesetzt werden, die als Letzte (gegen Ende des Steckvorganges) von ihrem Gegenkontakt berührt werden.According to another embodiment of the invention, the sensor may also comprise at least one electrical contact component of the plug-in device element, ie a typically metallic part with a freely accessible ("contactable") surface. An "activation" of the sensor can then take place in that the contact component (mechanical and in particular electrical) gets contact with an electrically conductive component of an inserted complementary plug-in device element. For example, could be provided in an outlet two spaced plug-in contact components between which upon insertion of a plug an electrical connection is made, closed by a circuit and a desired effect is triggered. By using electrical Contact components, the sensor function without moving parts and thus be made very robust. Moreover, since contact devices (sockets, plug pins) are always already present in plug-and-socket devices, they can advantageously be used simultaneously for the realization of the sensor in the described embodiment. In this case, it is preferred if those of the "normal" contact components are used for the realization of the sensor, which are touched as the last (towards the end of the mating process) of its counter-contact.
Bei einer anderen bevorzugten Ausführungsform der Erfindung ist der Verriegelungsstift so ausgebildet, dass er auf ein in den Steckkragen eingestecktes, komplementäres Steckvorrichtungselement eine Kraft ausüben kann, die in (oder entgegen) der Steckrichtung wirkt. Beispielsweise kann bei einer Drehung des Verriegelungsstiftes um seine Längsachse der Sperrabschnitt ähnlich wie der Zahn eines Zahnrades auf ein komplementäres Steckvorrichtungselement drücken, um dieses in Steckrichtung zu bewegen. Durch die Drehung des Verriegelungsstiftes kann somit der Einsteck- und/oder der Trennvorgang unterstützt werden. Eine aktive Unterstützung des Einsteckvorganges kann dabei insbesondere sicherstellen, dass die elektrischen Kontaktbauteile in der Steckvorrichtung ei nen ausreichenden Überlapp für eine sichere Stromübertragung bekommen.In another preferred embodiment of the invention, the locking pin is designed so that it can exert on a plugged into the plug collar, complementary plug device element a force acting in (or opposite) the plugging direction. For example, upon rotation of the locking pin about its longitudinal axis, the locking portion, like the tooth of a gear, may press on a complementary male member to move it in the insertion direction. By the rotation of the locking pin thus the insertion and / or the separation process can be supported. An active support of the insertion process can in particular ensure that the electrical contact components get in the plug-in device egg nen sufficient overlap for a secure power transmission.
Der Verriegelungsstift kann optional so ausgelegt werden, dass er von einem Benutzer manuell um seine Längsachse gedreht werden kann. Zusätzlich oder alternativ kann das Steckvorrichtungselement auch einen aktiven Antrieb enthalten, welcher den Verriegelungsstift von der Öffnungsposition in die Schließposition und/oder umgekehrt von der Schließposition in die Öffnungsposition bewegen kann. Die Energie für diesen Antrieb kann insbesondere der am Steckvorrichtungselement üblicherweise anliegenden Spannung entnommen werden. Der aktive Antriebes des Verriegelungsstiftes hat z. B. den Vorteil, dass die Verriegelung automatisch erfolgen kann, was komfortabel ist und ein versehentliches Vergessen verhindert. In Verbindung mit der vorstehend beschriebenen Ausführungsform kann der Antrieb ferner dafür sorgen, dass aktiv eine Kraft in (oder entgegen) der Steckrichtung auf ein komplementäres Steckvorrichtungselement ausgeübt wird, um dieses in einen elektrisch sicheren Steckzustand zu überführen.The locking pin can optionally be designed so that it can be manually rotated by a user about its longitudinal axis. Additionally or alternatively, the plug-in device element may also include an active drive, which can move the locking pin from the open position to the closed position and / or vice versa from the closed position to the open position. The energy for this drive can be taken in particular of the plug-in device element usually applied voltage. The active drive of the locking pin has z. B. the advantage that the lock can be done automatically, which is comfortable and prevents accidental forgetting. In connection with the embodiment described above, the drive can also be used for this purpose ensure that a force is actively exerted in (or against) the direction of insertion on a complementary plug-in device element, in order to convert this into an electrically safe plug state.
Der erwähnte aktive Antrieb kann optional einen Endlagensensor enthalten, welcher das Erreichen einer vordefinierten Endlage des Verriegelungsstiftes erkennt. Auf diese Weise kann verifiziert werden, dass sich der Verriegelungsstift in einer gewünschten Zielposition - beispielsweise der Schließposition - befindet. Weiterhin kann das Erkennen der Endlage dazu verwendet werden, den Antrieb zu steuern und ihn beispielsweise von einem Stellbetrieb auf einen (energiesparenderen) Haltebetrieb umzustellen.The mentioned active drive may optionally include an end position sensor, which detects the reaching of a predefined end position of the locking pin. In this way it can be verified that the locking pin is in a desired target position - for example, the closed position - is. Furthermore, the detection of the end position can be used to control the drive and to change it, for example, from a control operation to a (energy-saving) holding operation.
Gemäß einem zweiten Aspekt betrifft die Erfindung ein Steckvorrichtungselement mit einer Steckhülse, welche an ihrer Außenseite eine Einkerbung aufweist. Diese Einkerbung ist dabei vorzugsweise geometrisch so ausgestaltet, dass sie einen quer zur Steckrichtung verlaufenden zylinderförmigen Körper aufnehmen kann. Gemäß einer bevorzugten Ausführungsform kann die Einkerbung als eine um die Steckhülse umlaufende Nut ausgebildet sein. Typischerweise handelt es sich bei dem Steckvorrichtungselement um einen Stecker, es kann jedoch im Prinzip auch eine Dose/Kupplung sein.According to a second aspect, the invention relates to a plug-in device element with a plug-in sleeve, which has a notch on its outer side. This notch is preferably geometrically designed so that it can accommodate a transverse to the direction of insertion cylindrical body. According to a preferred embodiment, the notch may be formed as a circumferential groove around the socket. Typically, the plug-in device element is a plug, but in principle it can also be a can / coupling.
Das beschriebene Steckvorrichtungselement kann insbesondere zusammen mit einem Steckvorrichtungselement gemäß dem ersten Aspekt der Erfindung verwendet werden. Dazu sind die beiden Steckvorrichtungselemente von ihren Dimensionen und Formen her so komplementär auszubilden, dass die Steckhülse in den Steckkragen passt und dass im eingesteckten Zustand der Sperrabschnitt des Verriegelungsstiftes in die Einkerbung der Steckhülse eingreifen kann, um den eingesteckten Zustand zu verriegeln.The described plug-in device element can in particular be used together with a plug-in device element according to the first aspect of the invention. For this purpose, the two plug-in device elements of their dimensions and shapes are so complementary form, that the socket fits into the plug collar and that in the inserted state of the locking portion of the locking pin can engage in the notch of the socket to lock the inserted state.
Die Erfindung betrifft ferner ein Verfahren zur Verriegelung des Steckkragens eines Steckvorrichtungselementes, insbesondere eines Steckvorrichtungselementes der oben beschriebenen Art. Das Verfahren ist dadurch gekennzeichnet, dass ein Verriegelungsstift um seine Längsachse gedreht wird, wodurch wahlweise eine Aussparung oder ein Sperrabschnitt des Verriegelungsstiftes in dem Steckkragen zu liegen kommen.The invention further relates to a method for locking the plug-in collar of a plug-in device element, in particular a plug-in device element of the type described above. The method is characterized in that a locking pin is rotated about its longitudinal axis, whereby optionally a recess or a locking portion of the locking pin come to rest in the plug collar.
Das Verfahren entspricht in allgemeiner Form dem Betrieb des oben beschriebenen Steckvorrichtungselementes, so dass für die Erläuterung seiner Einzelheiten und Vorteile auf die dortige Beschreibung verwiesen werden kann.The method generally corresponds to the operation of the above-described plug-in device element, so that reference may be made to the description given there for the explanation of its details and advantages.

In dem in den Figuren dargestellten Beispiel befindet sich der erfindungsgemäße Verriegelungsmechanismus an der Steckvorrichtungsdose 100 bzw. Kupplung einer Kraftsteckvorrichtung.

Zu diesem Zweck ist erfindungsgemäß ein Verriegelungsstift 10 vorgesehen, der im Wesentlichen als ein länglicher Kreiszylinder ausgebildet ist und in einer zylindrischen Lagerungshülse 20 des Steckdosengehäuses drehbeweglich um seine Längsachse D (

Der Verriegelungsstift ist dabei vorzugsweise mit dem Rand der Aussparung 12 leicht schräg zur Achse der Unverwechselbarkeitsnut 102 positioniert, so dass er selbst bei unvermeidbaren Bauteil- und Maßtoleranzen in keinem Falle im öffnungsnahen Bereich in die Unverwechselbarkeitsnut hinragt, was eine Führungsnase unbeabsichtigt blockieren könnte.

Um die Verriegelung wieder aufzuheben, muss die gesamte Steckvorrichtung entweder stromlos geschaltet werden (der Verriegelungsstift 10 nimmt dann durch die Wirkung der Feder 22 seine Ruhestellung, d. h. die Öffnungsposition ÖP an), oder der Verriegelungsstift 10 muss durch einen Benutzer manuell in die Öffnungsposition zurückgedreht werden. Letzteres ist über geeignete mechanische Betätigungsmittel wie etwa einen Drehgriff ohne Weiteres möglich, was in den Figuren nicht näher dargestellt ist.To cancel the lock again, the entire plug-in device must either be de-energized (the locking
Alternativ könnte die erläuterte Funktion des Fühlers 111 auch durch mindestens eines der elektrischen Kontaktbauteile des Steckvorrichtungselementes erfüllt werden. Insbesondere könnte dies diejenige Kontaktbuchse der Steckdose 100 sein, die als Letzte mit einem zugehörigen Kontaktstift des Steckers 200 elektrischen Kontakt bekommt. Da ein solchermaßen realisierter Fühler unmittelbar bei der ersten Berührung der Kontaktbauteile aktiviert wird, andererseits jedoch für eine sichere Stromübertragung eine gewisse Mindestüberdeckung der elektrischen Kontakte wünschenswert ist, erfolgt vorzugsweise zusätzlich das oben erwähnte aktive Unterstützen des Einsteckens. Das heißt, dass nach dem ersten elektrischen Kontakt des Fühlers ein automatisches, aktives Unterstützen des Steckvorganges erfolgt, bis der gewünschte Mindestüberlapp hergestellt ist.Alternatively, the described function of the
