description

The invention relates to an electrical

Plug-in device system comprising a first and a second plug-in device element and a

Locking device, seen in the insertion direction of the second connector element, before the first

Plug device element is arranged.

Electrical plug-in devices such as connectors or couplings for power current according to DIN VDE 0623, EN 60309-2 ("CEE plug-in devices") typically contain a contact block with electrical in a housing

Contacts (pins or sockets). The contact module can be complemented by an access side

trained plug-in device element (coupling / socket or plug) are introduced to make electrical contact with the contact elements. It is known that

Access side of such plugs with a

To provide hinged lid to protect it in the unused state against the ingress of dirt and moisture and to prevent unwanted contact with live components. Before inserting a

complementary plug-in device element, such a hinged lid must be manually transferred by the user in an open position.

Furthermore, according to IEC 62196 (plugs, sockets, vehicle couplings and vehicle connectors - Conductive charging of electric vehicles), in particular to IEC 62196-1, or according to DIN EN 61851-1 (Electrical equipment of electric road vehicles - Conductive charging systems for

Electric vehicles) touchable conductive parts under

usual conditions, i. in error-free operation under normal use, and under

 Single fault conditions not too dangerous active

Be part of. The protection against electric shock is accordingly by the application of appropriate

To ensure protection in both normal operation and in case of failure, the protection against direct contact must consist of one or more measures that under normal conditions, a touch of

dangerous active parts. One at the

Power supply connected

Power supply unit must not have accessible,

dangerous active parts, even after removing parts that can be removed without tools. From DE 10 2012 101 755 AI is a

 Steckvorrichtungssystem known, which is a first

Plug-in device element and a compatible second plug-in device element, which with the first

Plug device element by movement in one

Plug-in direction can be joined together to connect electrical lines. The

 In this case, plug-in device elements are 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-in devices for

Electric vehicles act. The plug-in device system known from DE 10 2012 101 755 A1 has a Locking device, seen in the insertion direction of the second connector element, before the first

Plug device element is arranged and therefore the

Control of access to the first connector element is used. For this purpose, this closure device includes a rotatably mounted rotary ring with a

Passage opening into which the second

Plug device element can intervene rotatably,

at least one aperture, which between a

Lock position in which they are the first

 Plug device element (seen from the insertion direction) at least partially obscured, and an opening position in which it gives access to the first plug device element is free to move, and coupling means, via which a rotational movement of the rotary ring in a movement of the diaphragm from the closed position into its

Opening position is converted. The handling of the electrical plug-in device system of DE 10 2012 101 755 AI is therefore based on the fact that the rotational movement of the rotary ring by the second plug-in device element by means of further coupling means a diaphragm of the

 Closing device transferred to 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, the disadvantage of this solution is in particular the complexity of the system due to the large number to call together interacting components.

Furthermore, in the electrical plug-in device system of DE 10 2012 101 755 A1 locking means are provided by which the mobility of the diaphragm and / or the rotary ring is blocked in the closed position, wherein the

Blocking is solved only by acting in the direction of insertion pressure on the panel. For this purpose, however, the aperture is additionally against a restoring force in

Store plug-in direction displaceable, so that the panel must ultimately be movably mounted in several dimensions or along several levels, which can easily lead to an unwanted jamming and subsequent jamming of the panel, so that this total

shortened life of this plug-in device system results.

Against this background, an object of the present invention, for a generic

Plug-in device system, which is a first

 Plug-in device element and a compatible second plug-in device element, which with the first

Plug device element by movement in one

Plug-in direction can be joined together to connect electrical lines, a secure,

in particular 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 to this problem are in particular by a electrical connector system and a

Locking device given with the features of claim 1 or claim 2. Further functional

Embodiments are included in the subclaims.

The invention is based on an electrical

Plug-in device system, which is a first

Plug-in device element and a compatible second plug-in device element, which with the first

Plug-in device element in a plug-in direction

can be joined together, as well as a

 Locking device, which, viewed in the insertion direction, is arranged in front of the first plug-in device element. The invention now proposes that the

Closure device for such

 Plug-in device a sliding bezel with a

Passage opening contains, 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

Direction of insertion, between a closed position, i. in which the sliding panel, the first connector element seen in the insertion direction, at least partially hidden, and an opening position, i. in which the sliding panel the access to the first plug device element is free, is displaced. Furthermore, the closure device contains at least one locking means, by which the

Displaceability of the sliding diaphragm in the

Lock position is blocked and that by in

Compression direction acting on the locking means is released, wherein the locking means in the Closing position and viewed in the insertion direction, behind the sliding bezel is arranged and extends into the

Area of the passage opening extends. The plug-in device elements are alike

typically designed as a "can" or "coupling" on the one hand and as a "plug" on the other hand, wherein it is preferably in the context of the present invention to

Power plug devices or charging devices for electric vehicles according to the standards IEC 62196 and DIN EN 61851 acts.

Although the passage opening of the sliding panel can basically be of any desired design, as long as it passes the second plug-in device element up to the latter

Assembling with the first connector element allows. For a preferred rotationally fixed engagement of the plug-in device element in the passage opening, this may have an inner contour, which at least partially a non-circular outer contour of the second

 Plug device element corresponds, so that suitably the rotationally fixed engagement again takes place by positive engagement of the passage opening itself. Characterized in that also the at least one locking means through the passage opening with pressure to

is acted upon to effect its release, the closure device can be designed with high security against misuse by a release of the locking means and a displacement of the sliding panel can be possible only by the "right" second connector element generate. Also, by choosing the arrangement of the at least one locking means are ruled out with high reliability that can be released by a tool or by a one-handed operation when unplugged the second plug-in 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 rotary movement of the rotary ring in a

Movement of the aperture is converted, are not required. Further, since the at least one locking means in the closed position and viewed in the insertion direction, is arranged behind the sliding panel and extends into the region of the passage opening, thus directly and directly on the latter a pressure for releasing the second plug device element

Arresting be exercised, so that the

 Sliding diaphragm must be movably mounted only in one dimension or along a plane. An unintentional

Tilting or jamming of the sliding bezel can thus be substantially ruled out. The

Plug-in device system according to the invention thus comes with compliance of the standards IEC 62196 and DIN EN 61851 with a much smaller number of components and is less complex overall. The handling to control the access of the second

Plug-in device element in a direction of insertion to the complementary first plug-in device element, wherein the Sliding shutter in the closed position blocks access to the first plug device element, takes place in that the second plug device element brought into engagement, in particular rotationally fixed engagement with the arranged in the aperture passage opening and then pressed in the insertion direction until the resulting pressure of the second plug device element at least one or each locking means for

Release of the displaceability of the sliding panel transversely to the direction of insertion, in particular perpendicular to the direction of insertion triggers, then the second plug-in device element is moved transversely to the direction of insertion, and thus in particular perpendicular to the direction of insertion, so that the resulting

Displacement of the second connector element, the sliding panel from the closed position in the

 Open position transferred in which it gives access to the first connector element free, whereupon finally the second connector element by

Movement along the direction of insertion into the first

Plug device element can be inserted.

According to a preferred embodiment it is proposed that the at least one or each locking means against a restoring force to first spring means

Movable and stored in the

 Closing position of the sliding panel is engaged with a recess formed on this.

In addition, the at least one or each locking means expediently has a run-on slope which points towards the opening position and / or the sliding cover for the at least one or each locking means

Direction of the closing position looking starting slope, and the at least one or each locking means can by displacing the sliding panel from the

 Opening position in the closed position from the released state back into engagement with one each

associated recess are transferred to the sliding bezel. As a result, a renewed engagement of the at least one or each locking means for

Blocking the shutter position by alone

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, there is thus a return displacement of the sliding panel from the opening position to the closing position solely by pulling the second plug-in device element out of the second

Plug device element allows.

According to a preferred embodiment, it is proposed that the closure device at least two

 Locking means, in particular decoupled from each other locking means comprises, which in the

Closing position coming from opposite directions to the area of the passage opening

extend. Consequently, each locking means must be operated separately, but all at the same time, around the

Move sliding panel in the open position. In conjunction with the opposing arrangement is thus again increased security against uncontrolled access to the first connector element given. In principle, however, can also be another

Arrangement of the locking means provided and / or be sufficient. According to a preferred embodiment, it is proposed that the closure device be an actuator, in particular an electric servomotor, for locking the

Closing position of the sliding diaphragm is assigned. This can e.g. mechanically driving a blocking element, which for locking the closure position the

 Move option locks, e.g. 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 is further

suggested that the actuator also when dissolved

Blocking the at least one or each

 Arresting agent is effective in the closed position, wherein with the actuator, for. also one

 Signaling device can be signal-coupled, which forwards a switching signal to the actuator, whereupon the actuator, the blocking element mechanically

drives to release the engagement of the locking element in the recess.

According to a preferred embodiment, it is proposed that with the closure device a connector lock is coupled, which is completely in the first

Plug-in element inserted second

Plug device element the second

Steckvorrichtungselement in this position initially to Release of a current flow between the first and the second plug-in device element locked. To

Termination of the current flow can then, e.g. by means of a signaling device coupled to the connector locking signaling device, a release of the second

Plug device element done.

The invention will be described below with reference to a preferred embodiment with reference to the figures

exemplified in more detail. Showing:

Lock position in the opening position and back.

The Fign. 1 to 3 show various 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 plug device element 20, which in a plugging direction "x" with the first

Plug device element 10 can be joined together. The second connector element is e.g. to see in Figures 4 to 6.

Fig. 1 shows a view in the insertion direction "x" seen, Fig. 2 is a along the section line AA of Figure 1 at least partially cut view sketch, wherein the plugging direction "x" is displayed, and Figure 3 is a perspective view of the sketch Embodiment of Figure 1. The figures 1 to 3 can also be seen that the plug-in device system shown a

Closure device 100, which, again in

Plug direction "x" considered before the first

Plug-in device element 10 is arranged. The

Closure device 100 includes a sliding panel 110 with a through hole 111 into which the second

Plug device element 20 can engage, in particular can engage rotationally. The closure device can, as shown in the figures, one of several

Form housing parts composite housing, in which the sliding panel is inserted and as described below, is suitably performed. The sliding panel is in Figures 1 to 3 in a closed position and thus at least partially obscured access to the first connector element. The passage opening 111 serving as a passage for the second plug-in device element for joining both plug-in device elements is laterally offset in this position of the sliding panel to the first plug-in device element 10, according to figures 1 to 3 above the first plug device element 10, and expediently conceals at least the plug device contacts of the first

Plug-in element completely. The

 Plug-in device contacts are thus completely inaccessible and in the Fign. 1 to 3 therefore not visible.

As will be described below, the

Sliding panel 110, however, transversely to the direction of insertion, in the illustrated embodiment, perpendicular to the insertion direction "x", between the closed position shown and an open position slidably, in particular along the arrows shown on the sliding panel 110, i. 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 released to release the displaceability. Appropriately contains the

Closure device 100 at least two

Locking means 120. The at least one or each locking means 120 is preferably arranged so that it is considered according to the figures 1 to 3 in the closed position and in the plugging direction "x", conveniently located behind the sliding panel and into the region of the passage opening 111th extends.

The at least one or each locking means 120 is also useful against a restoring force on an associated first spring means 125th

displaced and stored in the

Locking position of the sliding panel 110 preferably in each case a recess 115 on the sliding panel 110 a. Any displacement of the sliding panel in the direction of the arrows shown on the sliding panel 110 is thus

initially prevented. Furthermore, it can already be seen from FIGS. 1 to 3 that the sliding panel 110 is expediently displaceably mounted against a restoring force on a second spring device 130 in the direction of the opening position. However, the at least one or each locking means 120 must first be released from the engagement in order to shift the sliding panel 110 accordingly

enable. Moreover, in the case of at least two locking means 120, these are expedient of one another

decoupled, so that consequently each locking means must be operated separately, but all must be operated simultaneously to the sliding panel in the

To move the opening position. Furthermore, the locking means 120 in the

Embodiment according to FIGS. 1 to 3 at least two locking means, which come in the closed position coming from opposite directions to the

Area of the passage opening 111 extend. Basically, however, is another arrangement of

Arrestierungsmittel 120 possible, if this in

Plug direction "x" acting pressure on the

Arrestierungsmittel 120 can be solved.

The second spring means 130 may be, for example, as shown in FIGS

Figures indicated, a be arranged between the sliding panel 110 and a housing wall enclosed by the closure device compression spring, their restoring force

Direction of the lock position acts. Such

Compression spring in the relaxed state, the first

Plug device element at least partially

cover. However, in a modification, e.g. also one

Tension spring be provided as spring means 130, which is then to be arranged such that their restoring force

can act accordingly from the direction of the opening position.

In order to move the sliding panel from the closed position to the open position, in which the mating or merging of the first and second

Plug-in device elements is possible, it is first necessary to insert the second plug-in device element 20 in the through hole 111, as shown in FIGS. 4 to 6 shown. In this case, it can be seen in particular from FIG. 5 that the locking device or locking means 120 is or are still in its blocking position. Only by further pressure exerted by the second plug device element 20 in the plugging direction "x" are the or the locking means 120 is actuated, 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 shutter 110 released to allow her a corresponding displacement in the direction of opening position.

By preferentially laying out the passage opening 111 such that a rotationally fixed engagement of the second

 Plug device element 20 is given in this through hole 111, the security can be increased so that only a "right" or uniquely fitting 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 can already correct positioning or alignment of the second

Plug-in device element 20 with respect to the first

Plug-in device element 10 permanently preset.

If each locking means 120 is released from its blocking position (FIG. 8), the sliding panel can then be moved simply by moving the second connector element 20 in the direction of the open position, as shown in FIGS. 7 to 9 to see. Is the sliding panel, as shown in Figs. 10 to 12, to see in the

Opening position shifted, is the first

Plug-in device element 10 no longer from the

Sliding panel covered and the second

Plug-in device element 20 can easily continue through the Through opening 111 in the direction of the first

 Plug-in device element 10 are guided until the second plug-in device element 20 with the first

Plug-in device element 10 is joined together. One

Current flow between the first and the second

 Plug-in device element, e.g. for charging batteries of electric vehicles, can then be released.

Preferably, as shown sketchily in the figures, further comprises a connector lock 40 with the

 Locking device 100 coupled, in such a way that in the opening position of the sliding panel 110 and fully inserted into the first connector element 10 second connector element 20, the second connector element in this position initially locked to enable a flow of current between the first and the second connector element. For this, e.g. at least one recess 25 (Figures 5, 8) may be provided on the second plug-in device element 20, into which of the plug lock 40 in the opening position of

Sliding panel 110 and at fully into the first

Plug-in device element 10 inserted second

Plug device element 20 is engaged for locking. After completion of the current flow, then, e.g.

by means of a signaling device coupled to the connector latch signaling device (not shown in the figures), again a release of the second

Plug device element 20 done. If the second plug-in device element 20 is pulled out, it being expedient for the second plug-in device element 20 to be able to be pulled out first, if the current flow was previously is finished, 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 means 130, wherein the sliding panel 110 against the restoring force of the spring means 130 in

 Direction opening position is moved movable and thus the restoring force of the spring means 130 acts in the direction of the closure position, the sliding panel 110 alone by this restoring force in the direction

Closing position to be shifted, as shown in Figures 13 to 15.

Further, as described, each locking means 120 mounted displaceably displaceable against a restoring force to spring means 125, is also suitably each locking means 120 with a in the direction of

Opening slant view 128 and / or the sliding panel 110 for each locking means 120 with a view in the direction of the closure position

Run-on slope 118 provided (Fig. 14). each

 Locking means 120 can thus be transferred from the released state back into engagement with a respective recess 115 on the sliding panel in succession by solely moving the sliding panel 110 from the open position to the closed position. This is thus a renewed engagement of each locking means 120 for

Blocking the shutter position by alone

Return movement of the sliding panel from the open position to the closed position. A new 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 each associated spring device 125 possible.

It can also be seen from FIG. 13, with the second plug-in device element 20 pulled out correspondingly, that the first plug-in device element 10, e.g. is designed as a "can" or "clutch", and the second

Plug-in device element 20 consequently as a "plug".

As can be seen in particular in FIGS. 3, 6, 9, 12 and 15, the closure device 100 is optionally also assigned an actuator 30, in particular an electric servomotor, for locking the closure position of the sliding diaphragm. This can e.g. one in the figures

For clarity, not shown blocking element mechanically drive, which is used to lock the

 Lock position locks the possibility of displacement, e.g. in which the blocking element can engage in a recess (not visible in the figures) disposed on the panel and can be released therefrom for releasing the closing position. In this case, provision is made in particular for the actuator 30 to be open even when the blockage is released

Locking means 120 in the closed position

regardless of this is effective. Thus, e.g. with the

Actuator also be signal technically coupled (not shown in the figures) signaling device, which only upon receipt of a certain signal pulse out, for. 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.

In the following, further reference is made to FIGS. 16a and 16b or in the figures 17a to 22b illustrated preferred embodiments of a plug-in device system

Ladesteckvorrichtungen according to type 1 standard IEC 62196-2, which for single-phase charging up to 32 A (Europe) for the

Electric vehicles of the first generation from Japan, USA, etc. are designed to have, in addition to the necessary for the flow of current, i. E. which is the load or main stream

providing contacts (L, N and PE) over two

additional control contacts (CP and CS) for data transmission and interlock indication.

Is thus in such, designed as a coupling or plug charging device a

Locking mechanism for locking the

Charging plug device provided in the inserted state with a complementary to the plug charging device, this locking mechanism

Usually coupled to comply with required standards with the control contacts to indicate about this in the mated state, whether he is locked or not.

FIGS. 16a and 16b as well as FIGS. 17 to 22 also show that the plug-in device systems illustrated in these figures also each contain a closure device 100 which, in turn, in the plug-in direction "x".

considered, is arranged in front of the first plug-in device element 10. The closure device 100 in turn 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, in particular the

Figures 16a and 16b, one of several Form housing parts composite housing, in which the sliding panel is inserted and as described below, is suitably performed. For example, FIGS. 16a and 16b show a housing composed of a plurality of housing parts

Closing device 100, which in addition to the sliding panel 110, first arranged in front of the first plug-in device element 10 and this partially cladding

Housing body 112 includes and a Abdeckblende 113, wherein the sliding panel 110 is disposed between the housing body 112 and the Abdeckblende 113. At the

Cover panel 113 facing away from the housing body 112 may preferably be disposed 114 a seal. Furthermore, the closure device 100 includes in possible

 Execution of a hinged lid 116, which then expediently on the side facing away from the sliding panel 110

Abdeckblende 113 is held hinged, e.g. by means of a rivet 117a and / or a hinged lid spring 117b. Furthermore, the closure device 100 includes in possible

 Execution of a hinged lid seal 119 a, which is suitably inserted into a corresponding seal receptacle 119 b on the hinged lid 116. The access side of the

 Plug device element 10 is thus suitably protected in the unused state against the ingress of dirt and moisture.

The sliding panel 110 is, as shown in Figures 16a and 16b referenced, formed in such a way that

Closing position at least partially obscured access to the first connector element. In particular, the sliding panel 110 is in such a closed position 17a, 18a and 22a and thus at least partially obscures the access to the first plug-in device element. The passage opening 111 serving as a passage for the second plug-in device element for joining both plug-in device elements is located in this

Closing position of the sliding bezel in turn laterally offset to the first plug-in device element 10, according to Figures 16a and 16b and according to Figures 17c and 18c upward in

Relative to the first connector element 10 offset. In addition, the sliding panel 110 is particularly preferably designed in such a way that in the closed position it only hides access to the contacts of the first plug-in device element required for the flow of current, i. According to the embodiments of Figures 16a and 16b and Figures 17a to 22b of the contacts 11, as well as the embodiment according to FIGS. 17, 18 and 22 can be seen .. At least the necessary for the flow of current, i. which provide the load or main stream

Connector contacts, which according to the

 Embodiments of Figures 16a and 16b and Figures 17a to 22b, the contacts 11 are thus completely

inaccessible and in the Fign. 17a, 18a and 22a are therefore not or only partially to see.

As will be described below, the

Sliding panel 110, however, transversely to the direction of insertion, in the embodiments shown in Figures 16a to 22 perpendicular to the plugging direction "x", between the illustrated closure position and an opening position displaceable, in particular along the on the sliding panels 110th

illustrated arrows, ie in the illustrated Embodiments from top to bottom.

Due to the fact that the sliding panel 110 in the

Closure position only covers plug-in device contacts and in particular only the contacts 11, which are necessary for the flow of current and thus provide the load or main current, e.g. for providing a charging current, but not additional control contacts 12, the path to be covered between a

Closing position of an opening position considerably

reduced and a compact design allows.

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 which is released by acting in the direction of insertion "x" pressure on the locking means 120 to release the displaceability. Appropriately contains the

Closure device 100 at least two

Locking means 120. The at least one or each

Locking means 120 is preferably arranged so that it according to the figures 16a and 16b and 17c, 18c and 22b viewed in the closed position and in the plugging direction "x", conveniently located behind the sliding panel and extends into the region of the through hole 111.

The at least one or each locking means 120 is also useful against a restoring force on an associated first spring means 125th

displaced and stored in the

Locking position of the sliding panel 110 preferably in each case a recess 115 on the sliding panel 110 a. Any displacement of the sliding panel in the direction of the arrows shown on the sliding panel 110 is thus

initially prevented. Furthermore, it can be seen from FIGS. 16a, 16b and 17 to 22 that the sliding panel 110

expedient against a restoring force on a second

Spring device 130 in the direction of the opening position

is displaceably stored. In the figures 17a, 18a, 19a, 20a, 21a and 22a, such a second spring means 130 is always visibly sketched to better illustrate the sequence of movements during the insertion process.

However, the at least one or each locking means 120 must first be disengaged from the engagement to the

Sliding panel 110 a corresponding move too

enable. Moreover, in the case of at least two locking means 120, these are expedient of one another

decoupled, so that consequently each locking means must be operated separately, but all must be operated simultaneously to the sliding panel in the

To move the opening position. Further, a retaining device 126 may be provided, such as

For example, in Figs. 16a and 16b, with which the locking means or locking means e.g. can be held and protected on the side facing away from the cover 113 113 of the housing body.

Furthermore, the locking means 120 include in the

Embodiments according to FIGS. 16a and 16b and 17 to 22, at least two locking means, which extend in the closed position coming from opposite directions into the region of the passage opening 111. Basically, however, is another

Arrangement of the locking means 120 possible, if they in the plugging direction "x" acting pressure on the

Arrestierungsmittel 120 can be solved.

The second spring means 130 may be, for example, as shown in FIGS

Figures indicated, one between the sliding panel 110 and a covered by the closure device housing wall, in Fig. 16a occupied by the reference numeral 140, be 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. However, in a modification, e.g. Also, a tension spring may be provided as spring means 130, which is then to be arranged such that their restoring force corresponding to from the direction of

Opening position can act.

In order to move the sliding panel from the closed position to the open position, in which the mating or merging of the first and second

Plug-in device elements is possible, it is first necessary to insert the second plug-in device element 20 in the through hole 111, as shown in FIGS. 17c to 18c shown. It can be seen in particular from FIG. 17c that the one or more locking means 120 is or are still in its blocking position. Only by further pressure exerted by the second plug device element 20 in the plugging direction "x" (see Fig. 18c) are the or the locking means 120 is actuated, as shown expediently opposite

Restoring force of the first spring means 125, and thus released from the blocking position thereof and in consequence the sliding panel 110 released to her a allow appropriate displacement in the direction of opening position.

By preferentially laying out the passage opening 111 such that a rotationally fixed engagement of the second

 Plug device element 20 is given in this through hole 111, the security can be increased so that only a "right" or uniquely fitting 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 can already correct positioning or alignment of the second

Plug-in device element 20 with respect to the first

Plug-in device element 10 permanently preset.

If each locking means 120 is released from its blocking position (see Figures 18a to 18c), the

Sliding shutter then simply by moving the second connector element 20 in the direction of

Opening position to be moved, as in the Fign. 19a to 19c to see. Is the sliding panel, as shown in Figs. 19a to 20c to see in the open position

shifted, the first plug-in device element 10 is no longer covered by the sliding panel and the second

Plug-in device element 20 can easily continue through the passage opening 111 in the direction of the first

Plug-in device element 10 are guided (see Figures 20a to 20c) until the second plug-in device element 20 is joined to the first plug-in device element 10. A current flow between the first and the second Plug-in device element, eg for charging batteries of electric vehicles, can then be released.

Preferably, although not shown in detail in Figures 16a to 22 for reasons of clarity, in turn, a connector lock with the

Locking device be coupled, in such a way that in the opening position of the sliding panel 110 and when completely inserted into the first connector element 10 second connector element 20, the second connector element in this position initially locked to release a current flow between the first and the second connector element. For this, e.g. at least one recess 25 (Fig. 20c) may be provided on the second plug-in device element 20, into which of the plug lock in the opening position of

Sliding panel 110 and at fully into the first

Plug-in device element 10 inserted second

Plug device element 20 is engaged for locking. After completion of the current flow, then, e.g.

by means of a signaling device coupled to the connector latch signaling device (not shown in the figures), again a release of the second

Plug device element 20 done. Such

Signaling device may e.g. also with the

Control contacts 12 may be coupled.

If the second plug-in device element 20 is pulled out, it being expedient for the second plug-in device element 20 to be able to be pulled out only when the current flow has previously ended, the sliding bezel can simply be moved back again in the direction of the closure position. through the functional mounting of the sliding panel 110 on the spring means 130, wherein the sliding panel 110 against the restoring force of the spring means 130 in

Direction opening position is moved movable and thus the restoring force of the spring means 130 acts in the direction of the closure position, the sliding panel 110 alone by this restoring force in the direction

Closing position can be moved, as seen in Figures 21a to 22b.

Further, as described, each locking means 120 mounted displaceably displaceable against a restoring force to spring means 125, is also suitably each locking means 120 with a in the direction of

Opening slant view 128 and / or the sliding panel 110 for each locking means 120 with a view in the direction of the closure position

Run-up slope 118 provided (see Figures 16a, 16b and 19c). Each locking means 120 can thus in succession by solely shifting the sliding panel 110 from the

 Opening position in the closed position from the released state back into engagement with a respective

Recess 115 are transferred to the sliding panel.

As a result, there is a renewed intervention each

Locking means 120 for blocking the

 Closure position solely by backward displacement of

Sliding panel from the opening position into the

Given closure position. A new shift of the sliding panel 110 is then again only after

simultaneous actuation of each locking means 120 against the acting on this restoring force of the respective associated spring means 125 possible. FIGS. 16a to 22b also show that, even in the embodiments shown there, the first

Plug-in device element 10 e.g. is designed as a "can" or "clutch", and the second plug-in device element 20 consequently as a "plug".

Optionally, the closure device 100 still a

Actuator 30, in particular an electric servomotor, be assigned to lock the locking position of the sliding panel, as has been described with reference to Figures 3, 6, 9, 12 and 15.
