Description

The invention relates to an electrical plug-in device system comprising a first and a second plug-in device element and a closure device, which is arranged in front of the first plug-in device element. Furthermore, it relates to a closure device for such a plug-in device system and a method for controlling the access of a plug-in device element to another.

Electrical plug devices such as connectors or couplings for power after DIN VDE 0623 . EN 60309-2 ("CEE plug-in devices") or after IEC 62196 ("E-car charging connectors") typically include in a housing a contactor with electrical contacts (pins or sockets). In the contact module can be introduced from an access side forth a complementarily designed plug device element (coupling or plug) to make electrical contact with the contact elements. It is known to provide the access side of such connectors with a hinged lid to protect them in the unused state against the ingress of dirt and moisture and to prevent unwanted contact with live components. Prior to insertion of a complementary plug-in device element such a hinged lid must be manually transferred by the user in an open position.

Against this background, it was an object of the present invention to provide means for safe and robust control of the authorized access to a plug-in device element, which can be implemented in a small space.

This object is achieved by an electrical connector system according to claim 1, by a closure device according to claim 2, and by a method according to claim 3. Advantageous embodiments are contained in the subclaims.

• – Ein erstes Steckvorrichtungselement und ein dazu kompatibles zweites Steckvorrichtungselement, das mit dem ersten Steckvorrichtungselement durch Bewegung in einer Steckrichtung zusammengefügt werden kann. Derartige Steckvorrichtungselemente sind allgemein bekannt und dienen dazu, elektrische Leitungen miteinander zu verbinden. Die Steckvorrichtungselemente sind typischerweise als "Dose" bzw. "Kupplung" einerseits und als "Stecker" andererseits ausgebildet. Im Rahmen der vorliegenden Erfindung kann es sich insbesondere um Kraftsteckvorrichtungen oder Ladesteckvorrichtungen für Elektrofahrzeuge handeln.
• – Eine Verschlusseinrichtung, die vor dem ersten Steckvorrichtungselement angeordnet ist. Die Angabe "vor" bezieht sich dabei auf die vorstehend genannte Steckrichtung in dem Sinne, dass das zweite Steckvorrichtungselement zunächst die Verschlusseinrichtung passieren muss, bevor es das erste Steckvorrichtungselement erreicht. Die Verschlusseinrichtung dient somit der Kontrolle des Zugangs zum ersten Steckvorrichtungselement.

According to its first aspect, the invention relates to an electrical connector system comprising the following components:

• A first connector element and a second connector device compatible therewith, which can be assembled with the first connector element by movement in an insertion direction. Such plug-in device elements are well known and serve to connect electrical lines with each other. The plug-in device elements are typically designed as a "can" or "clutch" on the one hand and as a "plug" on the other hand. In the context of the present invention may be in particular power connectors or charging connectors for electric vehicles.
• - A closure device which is arranged in front of the first plug-in device element. The term "before" refers to the aforementioned plug-in direction in the sense that the second plug-in device element must first pass through the closure device before it reaches the first plug-in device element. The closure device thus serves to control the access to the first connector element.

• a) Einen drehbeweglich gelagerten Drehring mit einer Durchgangsöffnung, in die das zweite Steckvorrichtungselement drehfest eingreifen kann. Die geometrische Form des "Drehringes" kann quasi beliebig sein und muss nicht unbedingt einem geschlossenen "Ring" im engeren Sinne entsprechen. Ebenso kann die "Durchgangsöffnung" des Drehringes beliebig ausgebildet sein, solange sie ein (teilweises) Passieren des zweiten Steckvorrichtungselementes ermöglicht. Schließlich kann ein "drehfestes Eingreifen" des Steckvorrichtungselementes in den Drehring an beliebiger Stelle erfolgen, wobei die drehfeste Verbindung vorliegen muss, wenn sich das zweite Steckvorrichtungselement in der Durchgangsöffnung befindet. Besonders bevorzugt ist es, wenn die Durchgangsöffnung eine Innenkontur hat, welche zumindest teilweise einer unrunden Außenkontur des zweites Steckvorrichtungselementes entspricht; in diesem Falle erfolgt der drehfeste Eingriff durch Formschluss an der Durchgangsöffnung selbst.
• b) Mindestens eine Blende, welcher zwischen einer Verschlussposition, in der sie das erste Steckvorrichtungselement (aus Steckrichtung gesehen) zumindest teilweise verdeckt, und einer Öffnungsposition, in der sie den Zugang zum ersten Steckvorrichtungselement frei gibt, bewegen lässt. Die Blende kann geometrisch beliebig geformt und in beliebiger Richtung(verschiebe-, schwenk-, und/oder dreh-)beweglich sein. Besonders bevorzugt ist es, wenn die Blende im Wesentlichen plattenförmig ist und in der Plattenebene bewegt werden kann, da sich dann besonders flache Bauformen verwirklichen lassen. Die Bewegung der Blende erfolgt zudem vorzugsweise in einer Ebene senkrecht zur Steckrichtung.
• c) Kopplungsmittel, über welche eine Drehbewegung des Drehringes in eine Bewegung der Blende von der Verschlussposition in ihre Öffnungsposition umgewandelt wird.

Furthermore, the plug-in device system is characterized in that the closure device contains the following components:

• a) a rotatably mounted rotary ring having a through hole into which the second plug device element can engage rotatably. The geometric shape of the "turning ring" can be virtually arbitrary and does not necessarily correspond to a closed "ring" in the strict sense. Likewise, the "passage opening" of the rotary ring may be formed as long as it allows a (partial) passing of the second plug device element. Finally, a "rotationally fixed engagement" of the plug device element in the rotary ring can be made at any point, wherein the rotationally fixed connection must be present when the second plug device element is in the through hole. It is particularly preferred if the passage opening has an inner contour which at least partially corresponds to a non-circular outer contour of the second plug-in device element; In this case, the rotationally fixed engagement takes place by positive engagement at the passage opening itself.
• b) At least one panel, which between a closure position in which it at least partially conceals the first plug-in device element (seen from the insertion direction), and an opening position in which it gives access to the first plug device element, move. The diaphragm can be geometrically arbitrarily shaped and in any direction (sliding, pivoting, and / or rotatable) to be movable. It is particularly preferred if the diaphragm is substantially plate-shaped and can be moved in the plane of the plate, since then particularly flat designs can be realized. The movement of the diaphragm is also preferably in a plane perpendicular to the direction of insertion.
• c) coupling means, via which a rotational movement of the rotary ring is converted into a movement of the diaphragm from the closure position to its open position.

Since the closure device is physically and as a disposable product separable from the plug device elements, the invention further relates to an independent closure device for controlling the access of a second plug device element to a complementary first plug device element with the features of the independent claim 2.

• – Mindestens eine Blende blockiert (anfänglich) in einer Verschlussposition den Zugang zum ersten Steckvorrichtungselement.
• – Das zweite Steckvorrichtungselement wird in einen drehfesten Eingriff mit einem Drehring gebracht und anschließend gedreht, wobei es den Drehring entsprechend mitnimmt.
• – Die Drehung des Drehringes überführt die Blende in eine Öffnungsposition, in der sie den Zugang zum ersten Steckvorrichtungselement frei gibt.
• – Das zweite Steckvorrichtungselement wird durch Bewegung entlang einer Steckachse in das erste Steckvorrichtungselement eingeführt. Die Steckachse kann dabei insbesondere dieselbe Achse sein, um welche zuvor die Drehung des zweiten Steckvorrichtungselementes unter Mitnahme des Drehringes erfolgt ist.

Finally, the invention relates to a method for controlling the access of a second plug-in device element to a complementary first plug-in device element, comprising the following steps:

• - At least one shutter blocks (initially) access to the first connector element in a closed position.
• - The second plug-in device element is brought into a rotationally fixed engagement with a rotary ring and then rotated, wherein it entrains the rotary ring accordingly.
• - The rotation of the rotary ring transfers the aperture in an open position in which it gives access to the first connector element free.
• The second plug-in device element is inserted into the first plug-in device element by movement along a plug-in axis. The thru-axle may be in particular the same axis about which previously the rotation of the second plug device element is carried out with entrainment of the rotary ring.

The electrical connector system, the closure device, and the method rely on the rotational movement of a (second) connector element to open a shutter, thereby providing access to a complementary (first) connector element. Since this approach further requires the rotationally fixed engagement of the (second) connector element in a rotary ring, it can be designed with a high level of protection against abuse by rotation of the rotary ring can be produced only by the "right" connector element and not abusive by a possible Tool or by hand.

In the following, various developments of the invention will be described, which can be implemented both in the plug-in device system, in the closure device, as well as in the process.

Preferably, a plurality of panels are provided, which together cover the access to the first plug device element in its closed position. The path of a single shutter from its closed position to its open position can be reduced in this way. It is particularly preferred if there are two diaphragms which in the closed position cover one part in each case (eg in each case half) of the first plug-in device element and are preferably movable in opposite directions. By moving in opposite directions can be achieved that largely compensate for interference or resistance forces each other.

The conversion of the rotational movement of the rotary ring into a movement of the diaphragm can be generated in various ways, which depend not least on the nature of the mobility of the diaphragm. In particular, the rotary ring may have arranged on a circular arc teeth, which are in engagement with a rack on the panel. In this way, the rotational movement of the rotary ring in a linear movement of the rack - and thus the associated aperture - convert.

According to another embodiment of the invention, the closure device on locking means by which the mobility of the diaphragm and / or the rotary ring is blocked in the closed position, wherein the blockage is released only by acting in the direction of insertion pressure on the panel. Such acting in the insertion direction pressure can be generated in a natural way by applying the second plug device element to the closure device, since the second plug device element for the desired assembly with the first plug device element must be moved anyway in the direction of insertion. The normal sequence of movements when plugging leads thus almost automatically to a release of the locking means. On the other hand, simply turning the rotary ring (without pressure on the panel), as can occur during an abusive opening attempt, does not lead to an opening of the closure device, since any movement of the panel and / or rotary ring is prevented by the locking means.

The structural realization of the locking means can be done in various ways. For example, the panel may be slidably mounted against a restoring force in the insertion direction. A (sufficiently large) pressure on the panel can then lead to their displacement in the insertion direction, which in turn can be used to cancel the blockage of the locking means.

The locking means may in particular comprise projections which engage in holes. In this way, movement of the projections perpendicular to their axis can be blocked. The projections may be located, for example, on the rotary ring or on the housing of the closure device and the holes on the panel, or vice versa. A pressure on the panel in the direction of insertion then has to cause the projections to emerge from the holes and become freely movable. This can In particular, in the embodiment described above be achieved in that the aperture moves together with their holes (or projections) in the insertion direction, while the projections (or holes) remain stationary.

The locking means described prevent the closure device can be opened only by a torque on the rotary ring. However, this protection could possibly be circumvented by directly attaching to the diaphragm manipulation attempts, while a pressure is exerted on the diaphragm, which solves the blockage of the locking means. In order to prevent such manipulations, the closure device can optionally be provided with securing means, by means of which, in the closure position, movement of the orifice, which is generated solely by the direct application of force, and the orifice is blocked.

The securing means can be provided regardless of the presence of the locking means. However, particularly preferably, they are present in addition to the locking means and designed so that they are effective even when the locking means are released (i.e., when the diaphragm is pressed).

Advantageously, the securing means are further designed such that movement of the diaphragm, which is generated by an active rotation of the rotary ring, in the closed position is impossible. This means that the securing means cancel the generally effective in both directions motion and force coupling between the aperture and rotary ring at least for the closure position and possibly only in one direction can be effective (in the direction of the rotary ring to the aperture).

The above-described cancellation of the bidirectional coupling between the rotary ring and the shutter in the closed position can optionally be achieved by completely disabling the coupling near the closing position, while at the same time providing blockage of the shutter by the rotary ring (but not the other way around). In other words, in this embodiment, the securing means comprises a freewheel of the rotary ring relative to the diaphragm. Only when an active rotation of the rotary ring (by an authorized user) leaves the freewheeling area does the "normal" bidirectional coupling with the shutter (and the blockage of the shutter stop) so that further rotation of the rotary ring will produce the desired opening Can effect aperture.

A movement blockage acting only on the rotary ring on the diaphragm (without simultaneous blocking of the rotary ring) can be achieved, for example, if the securing means comprise two points of diaphragm on the one hand and rotary ring in the closed position on the other hand, with the possible directions of movement of these points being perpendicular to one another. In this case, the point of contact of the rotating ring can "block the way" of the contact point of the diaphragm and thus block movement of the diaphragm, while its own mobility (in the transverse direction) remains free. Furthermore, it is ensured by the mutually perpendicular directions of movement that a pressure of the diaphragm on the point of contact of the rotary ring has no force component, which could initiate a rotation of the rotary ring.

1 shows in a perspective exploded view the components of a closure device according to the invention 100 and the associated first plug-in device element, which in the example shown a socket 1 is (in principle, however, could be a plug). The locking device should be the access side of the socket 1 close when not in use and thus prevent unauthorized access. At the same time, however, the access to the socket 1 for a supplied in the insertion direction x complementary second plug device element (in the present case for a plug 2 ) to be possible. To achieve this, the closure device has 100 the following components:

• - A front panel 110 which terminates the closure device to the outside and which is typically integrated in the wall of a device, for example in the housing wall of a charging station for electric vehicles. The front panel 110 is in the 2 - 5 , and 10 - 12 for the sake of clarity not shown.
• - a turn ring 120 which rotates about the thru-axle x within the shutter 100 is stored. The rotary ring 120 is in 1 shown in its "opening position" in which he access the plug to the socket 1 free. On its outside, the turning ring 120 teeth arranged on a circular arc 121 on that in a freewheel 122 go over without teeth. By a spring (not shown) of the rotary ring 120 preferably in the closed position ( 2 ).
• - Two mirror images of each other arranged and otherwise identical panels 130 and 130 ' , These consist essentially of a diaphragm plate and a thus laterally connected rack 131 . 131 ' , The irises 130 . 130 ' are in 1 also shown in their open position, in which they access the socket 1 give freely. Through (with the housing 150 connected) springs 134 are the panels from the illustrated opening position to the closed position ( 2 ), in which they are at their abutting edges 135 . 135 ' touch. The abutting edges are preferably stepped in the x direction in order to close tight despite component tolerances. Other than shown, the abutting edges can optionally also be odd and have, for example, protuberances and corresponding indentations. As a result, starting from the closed position individual contact sockets of the socket 1 possibly still be covered over a longer path of movement.
• - A spring plate 140 on which the irises 130 . 130 ' are displaceably mounted in the z-direction.
• - A housing 150 in which the spring plate 140 (along with the panels 130 . 130 ' ) on springs 151 is displaceably mounted in the insertion direction x.

In the 2 to 5 is the closure device 100 (without front panel) in assembled condition. In detail shows 2 the closure device 100 with the panels 130 . 130 ' and the rotary ring 120 in the closed position. The edges 135 . 135 ' the panels touch and the access to the outlet is obscured. 3 shows the closure device 100 in the same condition with attached plug 2 ,

4 shows the closure device 100 with the panels 130 . 130 ' and the rotary ring 120 in the opening position, in which access to the socket 1 free is. 5 shows this condition with attached plug 2 ,

Opposite the closing position is the turning ring 120 rotated in the opening position by about 60 °. This rotation is with the help of the plug 2 possible, which with the non-circular outer contour of its front end in the form-fitting matching inner contour of the passage opening 126 in the rotary ring 120 rotatably engaged.

By turning the plug 2 around the thru-axle x (as well as pressure on the panels 130 . 130 ' , see below) rotates the rotary ring 120 with around the x-axis. About the engagement of his teeth 121 in the racks 131 . 131 ' the aperture 130 . 130 ' is the rotational movement of the rotary ring 120 while in opposite translation movements of the aperture 130 . 130 ' converted (in positive and negative z-direction). The panels are thereby moved to their open position.

So that the closure device 100 can not be opened without a plug by turning the rotary ring by hand or with a tool, the rotary ring runs 120 on the inner contour of the passage opening 126 very slim. Therefore, it offers hardly any attack surface for fingers or a tool. So he can essentially be safely operated only by the matching exactly to the inner contour front end of a plug.

In order to protect the rotating ring in the closed position in addition to an unauthorized confirmation, locking means are further provided, which hereinafter with the aid of 6 to 9 be explained in more detail. By the locking means is the mobility of rotary ring 120 and irises 130 . 130 ' blocked in the closed position, as long as this blockade is not solved by a special operation step. Just turning the turn ring 120 is therefore not enough to the closure device 100 to open.

In the embodiment shown in the figures, the locking means are realized in that on the back of the rotary ring 120 Protrusions in the form of locking pins 123 ( 15 ) are provided. These engage in corresponding holes 132 . 132 ' ( 1 . 13 ) of the apertures 130 . 130 ' when the bezel and bezels are in the locked position. Such a condition is in a sectional view in FIG 6 shown in which the plug 2 in the passage opening of the rotary ring 120 is inserted and depressurized on the panels 130 . 130 ' rests. A turn of the plug 2 around the piercing axis x is not possible in this state, since the locking pins 123 of the rotary ring 120 in the holes 132 . 132 ' engage the aperture and thus block the rotation.

In order to remove the blockage of rotating ring and the aperture, as in 7 shown a pressure in the insertion direction x on the panels 130 . 130 ' be exercised. Due to the sliding movement of the diaphragms 130 . 130 ' (and the spring plate 140 ) in the housing 150 Can the panels together with the spring plate 140 yield to such a pressure and move a piece (typically of the order of one millimeter) in the insertion direction x. These shifts in the direction of insertion is sufficient to the locking pins 123 of the rotary ring 120 from the holes 132 . 132 ' the aperture 130 . 130 ' pull out, so that the movement blockade is released.

The rotary ring 120 can therefore subsequently as in 8th shown rotated in the open position and the closure device are thus opened. After opening the panels, the plug can 2 then completely in the socket 1 be plugged in what 9 is recognizable.

Out 9 It is further apparent that a collar 125 on the rotary ring 120 a groove overlapped, as shown, between the front end and the handle of a plug 2 can be trained. This prevents the rotary ring 120 or the aperture 130 . 130 ' dive into this groove and thus could block a retraction of the plug.

By the described locking means is prevented by a direct rotation of the rotary ring 120 the closure device can be opened, because only by a combination of this rotation with a pressure on the aperture opening is possible.

In addition, the invention optionally provides securing means, with which also a direct manipulation of the aperture 130 . 130 ' can be prevented. The securing means are intended in particular to prevent the closure device from being able to be opened by pressure on the panels in the insertion direction x (for releasing the locking means) and subsequent sliding of the panels in the z-direction.

This goal can be achieved, for example, by the securing means according to the 10 - 12 be achieved, in which the rotary ring 120 partially transparent. The rotary ring 120 has two sets on the back 124 (see. 15 ), in each of which a guide pin 133 respectively. 133 ' the aperture 130 respectively. 130 ' intervenes. In the lower part of 10 The scenery and the associated setting pin are highlighted in the drawing. The effect of these elements will be described below using the example of the upper gate 124 and the scenery pin 133 the upper panel 130 explained, because the functionality for the lower elements 124 . 133 ' analog (mirror image) is. in the right part of 10 are the relevant "points of contact" 124 and 133 from rotary ring 120 or aperture 130 shown separately again.

10 shows the rotary ring 120 and the irises 130 . 130 ' in the closed position. The scenes 124 and the scenery pin 133 have contact points, whose principle possible directions of movement v _D (backdrop 124 or rotary ring 120 ) and v _B (gate pin 133 or aperture 130 ) are perpendicular to each other. In other words, the scenery pin lies 133 in the dead center of the scenery 124 , One in the z-direction (v _B ) on the aperture 130 acting manipulation force can therefore produce no force component, the rotation of the rotary ring 120 could initiate. Thus, a shift of the aperture 130 permanently blocked. This realizes the desired securing of the closure device 100 against an abusive force approach to the panels 130 and 130 ' ,

The securing means described are completed by the fact that the rotary ring 120 a toothless freewheel 122 is provided. In the closed position is thus still no coupling of the rotary ring 120 with the racks 131 . 131 ' the aperture 130 . 130 ' in front. If such a coupling already existed, a force acting on the diaphragms in this way could cause the turning ring to rotate 120 generate and thus the blockage between guide pin 133 . 133 ' and scenes 124 cancel. Ultimately, it would be a question of the respective component tolerances, which of the two conflicting movement mechanisms (blockage by sliding pin 133 . 133 ' and scenery 124 or bidirectional movement coupling by teeth 121 . 131 ) Prevail. Through the freewheel 122 In this regard, a clear priority for the blockage between pin and link set.
