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 the insertion direction of the second plug device element, in front of the first plug device element.

Electrical plug devices such as connectors or couplings for power after DIN VDE 0623 . EN 60309-2 ("CEE plug-in devices") typically include in a housing a contact block with electrical contacts (pins or sockets). In the contact module can be inserted from an access side forth a complementary trained plug device element (coupling / socket 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.

Furthermore, z. B. after IEC 62196 (Plugs, sockets, vehicle couplings and vehicle connectors - Conductive charging of electric vehicles), especially after IEC 62196-1 , or after DIN EN 61851-1 (Electrical equipment of electric road vehicles - Conductive charging systems for electric vehicles) touchable conductive parts under normal conditions, ie when operated correctly under normal conditions of use, and under single fault conditions not to dangerous active parts. The protection against electric shock is to be ensured accordingly by the application of appropriate protective measures both during normal operation and in the event of a fault, the protection against direct contact must consist of one or more measures that prevents contact of dangerous active parts under normal conditions. A power supply unit connected to the power supply network must not contain any accessible, dangerous active parts, even after parts that can be removed without the aid of tools have been removed.

From the DE 10 2012 101 755 A1 For example, a plug-and-socket system is known which includes a first plug-in device element and a second plug-in device element compatible therewith that can be mated with the first plug-in device element by movement in a plugging direction to connect electrical leads together. The plug-in device elements are hereby typically designed as a "can" or "clutch" on the one hand and as a "plug" on the other hand, which are in particular power plug devices or charging plug devices for electric vehicles. The plug-in device system known from DE 10 2012 101 755 A1 has a closure device which, viewed in the plug-in direction of the second plug-in device element, is arranged in front of the first plug-in device element and thus controls the access to the first plug-in device element. For this purpose, this closure device includes a rotatably mounted rotary ring having a through hole into which the second plug device element can engage rotatably, at least one aperture which between a closure position in which it at least partially covers the first plug device element (seen from the insertion direction), and an opening position which allows access to the first plug-in device element, and coupling means, via which a rotational movement of the rotary ring is converted into a movement of the diaphragm from the closed position to its open position. The handling of the electrical plug-in device system of DE 10 2012 101 755 A1 is therefore based on the fact that the rotational movement of the rotary ring by the second plug device element by means of further coupling means converts a shutter of the closure device in an open position. Although this approach requires the rotationally fixed engagement of the second plug-in device element in a rotary ring, so that a high level of security against abuse can be given by a rotation of the rotary ring can only be generated by the "right" plug device element as possible and not abusive by a tool or Hand.

However, a disadvantage of this solution is in particular the complexity of the system due to the large number of interacting components.

Furthermore, in the electrical plug-in device system of DE 10 2012 101 755 A1 Locking means provided by which the mobility of the diaphragm and / or the rotary ring is blocked in the closed position, wherein the blocking is released only by acting in the direction of insertion pressure on the panel. For this purpose, however, the aperture is additionally slidably mount against a restoring force in the insertion direction, so that the aperture must ultimately be movably mounted in several dimensions or along several levels, which can easily lead to an unintentional Verkannte and subsequent jamming of the aperture, so that this Overall, a shortened life of this plug-in device system has the consequence.

Against this background, an object of the present invention is to provide a secure plug-in system having a first connector element and a second plug-in device member compatible therewith that can be mated with the first connector element by movement in a plugging direction to interconnect electrical leads , especially the Standards IEC 62196 and DIN EN 61851 sufficient yet more robust control of the authorized access to the first connector element with a reduced number of means than the previously described prior art.

Solutions of this object are given in particular by an electrical plug-in device system and a closure device having the features of claim 1 and claim 2, respectively. Further expedient refinements are contained in the subclaims.

The invention is based on an electrical plug-in device system which comprises a first plug-in device element and a second plug-in device element compatible therewith, which can be joined together with the first plug-in device element in a plug-in direction, and a closure device, which, viewed in the plugging direction, is arranged in front of the first plug-in device element.

The invention now proposes that the closure device for such a plug-in device system includes a sliding panel with a through opening, in which the second plug device element can engage, in particular rotationally engageable, and wherein the sliding panel transversely to the direction of insertion, in particular perpendicular to the insertion direction, between a closed position, d. H. in which the sliding panel, the first plug-in device element seen in the insertion direction, at least partially hidden, and an open position, d. H. in which the sliding panel the access to the first plug device element is free, is displaced. Further, the closure device includes at least one locking means by which the displaceability of the sliding panel is blocked in the closed position and which is solved by acting in the direction of insertion pressure on the locking means, wherein the locking means in the closed position and in the insertion direction, behind the sliding panel is arranged and extends into the region of the passage opening.

The plug-in device elements are likewise 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, they are preferably power plug devices or charging plug devices for electric vehicles according to FIGS Standards IEC 62196 and DIN EN 61851 is.

Although the passage opening of the sliding panel can basically be of any desired design, as long as it allows the second plug-in device element to pass through until it is joined to the first plug-in device element. For a preferred rotationally fixed engagement of the plug-in device element in the through hole, this may have an inner contour which at least partially corresponds to a non-circular outer contour of the second plug device element, so that expediently the rotationally fixed engagement takes place again by positive engagement at the passage opening itself.

Due to the fact that, in addition, the at least one locking means is to be pressurized through the passage opening in order to effect its release, the closure device can be designed with high security against misuse by detaching the locking means and displacing the sliding panel as far as possible only through the Create "right" second connector element. Also can be ruled out by the choice of the arrangement of the at least one locking means with high security that is solvable by a tool or by a one-handed operation when unplugged the second plug device element and the sliding panel is displaceable in the open position. In particular, for this purpose, the closure device can particularly suitably further comprise at least two locking means.

As a few significant advantages are therefore to be mentioned that due to the formation of a through hole directly on the sliding bezel, a rotary ring and coupling means, via which a rotational movement of the rotary ring is converted into a movement of the diaphragm, are not required. Further, since the at least one locking means is arranged in the locking position and in the insertion direction, behind the sliding panel and extends into the region of the passage opening, thus directly and directly on this a pressure for releasing the locking means can be exercised by the second connector element that the sliding panel must be movably mounted only in one dimension or along a plane. Unintentional jamming or jamming of the sliding diaphragm can thus be substantially ruled out. The plug-in device system according to the invention thus comes even with the fulfillment of the Standards IEC 62196 and DIN EN 61851 with a significantly smaller number of components and is less complex overall.

The handling for controlling the access of the second plug-in device element in a plug-in direction to the complementary first plug device element, wherein the sliding panel blocks access to the first plug device element in the closed position, takes place in that the second plug device element in an engagement, in particular rotationally fixed engagement with the in brought the aperture disposed through opening and then pressed in the insertion direction until the resulting pressure of the second connector element, the at least one or each locking means for releasing the displaceability of the sliding panel transversely to the direction of insertion, in particular perpendicular to the direction of insertion, then the second connector element transversely to the direction of insertion, and thus in particular is moved perpendicular to the plug-in direction, so that the resulting displacement of the second plug-in device element, the sliding panel from the closed position in transferred the opening position in which it gives access to the first connector element free, whereupon finally the second connector element can be introduced by movement along the direction of insertion into the first connector element.

According to a preferred embodiment, it is proposed that the at least one or each locking means is displaceably mounted against a restoring force on first spring means and is in the closed position of the sliding panel with a recess formed on this engaged. In addition, the at least one or each locking means expediently has a run-on slope which points in the direction of the opening position and / or the sliding cover for the at least one or each locking means has a run-on slope which points in the direction of the closure position, and the at least one or each locking means can be displaced by sliding Sliding panel from the open position to the closed position from the released state are again transferred into engagement with a respective zugeodneten recess on the sliding panel. As a result, a re-engagement of the at least one or each locking means for blocking the closure position is thus provided solely by return movement of the sliding panel from the open position to the closed position.

According to a preferred embodiment, it is proposed that the sliding panel is displaceably mounted against a restoring force on a second spring device in the direction of the opening position. As a result, a return movement of the sliding panel from the open position into the closed position is thus made possible solely by pulling the second plug-in device element out of the second plug-in device element.

According to a preferred embodiment, it is proposed that the closure device comprises at least two locking means, in particular decoupling means which are decoupled from one another and which extend in the closing position from opposite directions into the region of the passage opening. Consequently, each locking means must be operated separately, but all at the same time to move the sliding panel in the open position can. In conjunction with the opposing arrangement, a further increased security against uncontrolled access to the first plug-in device element is thus provided. In principle, however, a different arrangement of the locking means may be provided and / or sufficient.

According to a preferred embodiment, it is proposed that the closure device is assigned an actuator, in particular an electric servomotor, for locking the closure position of the sliding panel. This can z. B. mechanically driving a blocking element, which locks the possibility of displacement for locking the closure position, for. B. in which the blocking element engage in a recess arranged on the aperture and can be released to release the closure position from this.

According to a preferred embodiment, it is further proposed that the actuator is effective even when the blocking of the at least one or each locking means in the closed position, wherein with the actuator z. B. also a signaling device can be signal-coupled, which forwards a switching signal to the actuator, whereupon the actuator mechanically drives the blocking element to release the engagement of the blocking element in the recess.

According to a preferred embodiment, it is proposed that a plug lock be coupled to the closure device, which first locks the second plug device element in this position for releasing a current flow between the first and the second plug device element when the second plug device element is completely inserted into the first plug device element. After completion of the current flow can then, for. B. by means of a signaling device coupled to the connector latch signaling device, a release of the second connector element done.

The invention will be explained in more detail by way of example with reference to a preferred embodiment with reference to the figures. Showing:

The 1 to 3 show various elevational views of a preferred embodiment of a plug-in device system with a first plug-in device element 10 but still without a compatible second connector element 20 , which in a plugging direction "x" with the first plug-in device element 10 can be joined together. The second connector element is z. Tie 4 to 6 to see.

The 1 shows a view seen in the insertion direction "x", the 2 one along the section line AA of 1 at least partially cut view sketch, wherein the plugging direction "x" is displayed with, and the 3 a perspective view sketch of the embodiment according to 1 ,

The 1 to 3 It can also be seen that the plug-in device system shown a closure device 100 contains, in turn, in the direction of insertion "x" considered before the first connector element 10 is arranged. The closure device 100 contains a sliding panel 110 with a passage opening 111 into which the second connector element 20 can engage, in particular can engage rotationally. The closure device can, as can be seen from the figures, form a housing composed of several housing parts into which the sliding panel is inserted and, as described below, is suitably guided. The sliding panel is at the 1 to 3 in a closed position and thus at least partially obstructs access to the first connector element.

The passage opening serving as a passage for the second plug-in device element for joining both plug-in device elements 111 is in this position of the sliding panel laterally to the first connector element 10 offset, according to 1 to 3 above the first connector element 10 , and expediently completely conceals at least the plug-in device contacts of the first plug-in device element. The plug-in device contacts are thus completely inaccessible and in the 1 to 3 therefore not to be seen.

As will be described below, the sliding bezel 110 However, transversely to the direction of insertion, in the illustrated embodiment, perpendicular to the plugging direction "x", between the closed position shown and an open position slidably, in particular along the on the sliding panel 110 illustrated arrows, ie in the illustrated embodiment from top to bottom.

The closure device 100 further includes at least one locking means 120 , by which the displaceability of the sliding panel 110 is initially blocked in the closed position and by acting in the direction of insertion "x" pressure on the locking means 120 is solved to release the displacement. The closure device expediently contains 100 at least two locking means 120 , The at least one or each locking means 120 is preferably arranged to be in accordance with 1 to 3 considered in the closed position and in the insertion direction "x", conveniently located behind the sliding panel and into the region of the passage opening 111 extends.

The at least one or each locking means 120 is also expedient against a restoring force on an associated first spring means 125 displaceably mounted and engages in the closed position of the sliding panel 110 preferably in each case a recess 115 on the sliding bezel 110 one. Any movement of the sliding panel in the direction of the sliding panel 110 shown arrows is thus initially prevented. Furthermore, already is the 1 to 3 to see that the sliding bezel 110 expedient against a restoring force on a second spring device 130 is mounted displaceably movable in the direction of the opening position. The at least one or each locking means 120 however, must first be disengaged from the engagement to the sliding bezel 110 to allow a corresponding move. At least two locking means 120 Moreover, these are expediently decoupled from each other, so that consequently each locking means must be operated separately, but all simultaneously, in order to be able to displace the sliding panel into the open position.

Furthermore, the locking means comprise 120 in the embodiment of the 1 to 3 at least two locking means, which come in the closed position from opposite directions to the region of the passage opening 111 extend. In principle, however, is also another arrangement of the locking means 120 possible, provided that in the plugging direction "x" acting pressure on the locking means 120 can be solved.

The second spring device 130 can z. B., as indicated in the figures, one between the sliding panel 110 and one of the closure device enclosed housing wall arranged compression spring whose restoring force acts from the direction of the closure position. Such a compression spring can at least partially cover the first plug-in device element in the relaxed state. In a modification, however, z. B. also a tension spring as a spring device 130 be provided, which is then to be arranged such that the restoring force can act accordingly from the direction of the opening position.

In order to be able to move the sliding panel from the closed position to the open position, in which the insertion or merging of the first and second plug-in device elements is made possible, it is first necessary to use the second plug-in device element 20 in the passage opening 111 introduce, as in the 4 to 6 shown. Here is in particular the 5 to see that the one or more locking 120 still in its or its blocking position is or are. Only by further pressure exerted by the second connector element 20 in the plugging direction "x" are the or the locking means 120 operated, as shown expediently against the restoring force of the first spring means 125 , And thus released from the blocking position thereof and in consequence the sliding diaphragm 110 released to allow her a corresponding displacement in the direction of opening position.

By preferred laying out the passage opening 111 such that a rotationally fixed engagement of the second plug-in device element 20 in this passage opening 111 given, the security can be increased so that only a "right" or clearly matching second plug device element 20 can be used correctly and / or only such a separate but simultaneous pressing each locking means 120 can cause. Apart from that, this already allows the correct positioning or alignment of the second plug device element 20 with respect to the first connector element 10 permanently preset.

Is every locking device 120 released from its blocking position ( 8th ), the sliding panel can then simply by moving the second connector element 20 be moved in the direction of the opening position, as in the 7 to 9 to see. Is the sliding panel, as in the 10 to 12 to see moved to its open position, is the first plug-in device element 10 no longer covered by the sliding bezel and the second plug-in device element 20 just keep going through the through hole 111 in the direction of the first plug-in device element 10 be guided until the second connector element 20 with the first connector element 10 is joined together. A current flow between the first and the second plug device element, for. B. for charging batteries of electric vehicles, can then be released.

Preferably, as shown in the figures sketchy, also a connector lock 40 with the closure device 100 coupled, in such a way that it in the open position of the sliding panel 110 and completely into the first connector element 10 inserted second connector element 20 in that position first locks the second connector element in this position to enable current flow between the first and second connector elements. For this purpose, z. B. on the second connector element 20 at least one recess 25 ( 5 . 8th ), in which of the connector lock 40 in opening position of the sliding panel 110 and completely into the first connector element 10 inserted second connector element 20 is intervened for locking. After completion of the current flow can then, for. B. by means of a signaling device coupled to the connector latch signaling device (not shown in the figures), again a release of the second connector element 20 respectively.

Will be the second connector element 20 pulled out, expediently the second plug device element 20 can only be pulled out when the flow of current is completed before, the sliding panel can easily be moved back towards the shutter position. By means of the appropriate storage of the sliding panel 110 on the spring device 130 in which the sliding panel 110 against the restoring force of the spring device 130 is movable in the direction of opening position and thus the restoring force of the spring device 130 acting in the direction of the shutter position, the sliding bezel 110 be moved back towards the lock position only by this restoring force, as in the 13 to 15 to recognize.

Is also, as described, also any locking means 120 against a restoring force on spring devices 125 displaceably mounted, is also suitably any locking means 120 with a starting slope looking in the direction of the opening position 128 and / or the sliding bezel 110 for each locking device 120 with a start-up slope looking in the direction of the closure position 118 Mistake ( 14 ). Each locking device 120 can thus in consequence by solely moving the sliding panel 110 from the open position into the closed position from the released state again into engagement with a respective recess 115 be transferred to the sliding panel. As a result, there is thus a renewed intervention of each locking means 120 for blocking the closing position solely by shifting back the sliding panel from the opening position to the closing position. Another shift of the sliding panel 110 is then again only after simultaneous actuation of each locking means 120 against the force acting on this restoring force of the respectively associated spring device 125 possible.

Of the 13 Here is in accordance with pulled out second connector element 20 Furthermore, it can be seen that the first plug-in device element 10 z. B. is designed as a "can" or "clutch", and the second plug device element 20 hence as a "plug".

As in particular in the 3 . 6 . 9 . 12 and 15 to see is optional of the closure device 100 another actuator 30 , In particular, an electric servomotor, assigned to lock the locking position of the sliding panel. This can z. B. a in the figures for reasons of clarity not shown blocking element mechanically drive, which locks the possibility of displacement to lock the closure position, z. B. in which the blocking element in a arranged on the panel (not visible in the figures) recess and can be released to release the closure position from this. In this case, it is provided in particular that the actuator 30 even with dissolved blocking of each locking means 120 is independently effective in the closed position. So z. B. with the actuator and a (not shown in the figures) signaling device to be signal-coupled, which only after the receipt of a specific signal pulse out, z. B. by means of a coded chip card, a switching signal to the actuator forwards, whereupon the actuator mechanically drives the blocking element to release the engagement of the blocking element in the recess.
