FIG. 1 shows a schematic view of an exemplary embodiment of an electrical charging arrangement 100 according to the present application. Specifically, the electrical charging arrangement 100 is shown in the form of a charging station 100 that is set up to charge electric vehicles 112. For this, the

Electric vehicle 112 are connected in a known manner via a charging cable 110 to the electrical charging device 100.

In order to be able to deliver electrical power to a vehicle 112 in particular, the electrical charging arrangement 100 is connected to a current source 108, in the present case

(public) power grid 108, connected. For connection to the power grid 108, the electrical charging arrangement 100 has an electrical connection unit 106. The electrical connection unit 106 is coupled to the power network 108 via a cable. In particular for the delivery of the electrical power to an electric vehicle 112, the electric charging arrangement 100 has an electrical charging control unit 104. The charge control unit 104 may also have a charge controller (not shown) for controlling the output.

As can further be seen from FIG. 1, the charge control unit 104 is electrically (and mechanically) connected to the electrical connection unit 106 in FIG intended use of the electrical charging device 100 coupled via an electrical charging connector 102.

The only schematically shown in the present embodiment

Charging connector 102 includes a receptacle having a plurality of first contacts and a connector having a plurality of second contacts corresponding to the first contacts, the receptacle having at least one slidable protection plate having a plurality of openings corresponding to contact openings of the first contacts; wherein the protective plate is arranged to close the contact openings of the first contacts in an unconnected state, and wherein the protective plate is arranged to cooperate with the plug, that by inserting the plug in the

Socket a displacement of the protective plate is effected such that the second contacts are inserted through the openings of the protective plate in the contact openings of the first contacts. A more detailed description of exemplary charging connectors 102 according to the application is provided below.

Figures 2a and 2b each show a schematic sectional view of a

Embodiment of an electrical charging connector 202 according to the present application in an unconnected state of the charging connector 202 (Fig. 2a) and in a connected state of the charging connector 202 (Fig. 2b). The illustrated charging connector 202 may be used in the

electric charging device 100 are used according to the figure 1.

The charging plug connection 202 comprises a plug 218 and a plug socket 216 corresponding to the plug 218. This is to be understood as meaning that the plug 218 can be electrically and mechanically coupled to the plug socket 216.

The plug 218 comprises a plurality of second contacts 222, in particular in the form of second contact pins 222. By way of example, four second contacts 222 are shown here by way of example. It is understood that more or less contacts 222 can be provided. In addition, the plug 218 comprises a plug guide module 232, which according to a preferred embodiment in the present case is formed as a receptacle 232. The receptacle 232 has at least one second abutment surface 236, which in the present case is formed by a side wall of the receptacle 232. In particular, the abutment surface 236 may have a stop edge 237 to at least partially contact a corresponding first abutment surface 234 during the insertion process. The function of the illustrated plug guide module 232 will be described in more detail below.

The socket 216 includes a plurality of first contacts 220, each having a contact opening 224. The first contacts 220 correspond to the second contacts 222 in this case. In other words, the second contact pins 222 can be inserted into the first contacts 220 to allow current to flow from the first contacts 220 to the second contacts 222 (or vice versa). In addition, the socket 216 has a sliding protective plate 226. The protective plate 226 is in particular movable on the

Top of the socket 216 stored so that it is displaceable in a direction of displacement 240. For example, the female connector 216 may have a groove for guiding the protective plate 226.

The sliding protective plate 226 (also called shutter) has a plurality of openings 228. The openings 228 of the protective plate 226 correspond to the contact openings 224 of the first contacts 220. This is to be understood in particular that the position of the openings 228 to each other to the position of

Contact openings 224 corresponds to each other, the number of openings 228 corresponds to the number of contact openings 224 (it is understood that more openings may be provided) and the shape, in particular the diameter, of the openings 228, substantially identical to the shape, in particular the Diameter, which is contact openings 224. As can further be seen from FIGS. 2 a and 2 b, the plug socket 216, in particular the protective plate 226, has a socket guide module 230. The

Jack guide module 230 corresponds (from its shape and location on top of guard plate 226) to plug guide module 232 of plug 218. The jack guide module 230 is presently in accordance with a

preferred embodiment formed as a projection 230 which is disposed on the surface of the protective plate 226. The projection 230 in this case extends from the surface of the protective plate 226 parallel to the insertion direction 238.

The projection 230 has a first abutment surface 230. In this case, the first abutment surface 234 is formed in particular by a taper, for example a bevel, of the protrusion 230 in the direction of the free end of the protrusion 230. The abutment surface 234 is formed in particular by an obliquely formed side surface of the projection. By this is meant that the angle between the plane of displacement (or here the surface of the guard plate 226) is less than 90 ° (e.g., between 5 ° and 85 °, especially between 15 ° and 75 °).

In addition, at least one return element 242 is attached to the protective plate 226. In the present case, the restoring element 242 is a spring element which is arranged in particular between the socket 216 and the protective plate 226 and is fastened to the corresponding elements. The return element 242 is arranged to apply a force to the protective plate 226 in opposite directions

Exercise displacement direction 240. In this way, it can be achieved in an automatic manner that in the unconnected state (FIG. 2 a) the first contacts 220 or their contact openings 224 are closed.

The operation of the position plug connection 202 will be described in more detail below

described.

To change from the unconnected state of the position plug connection 202 in the

connected state of the position plug connection 202 is the plug 218 during insertion in the insertion direction, for example, by a user moves. By this insertion, the projection 230 engages in the receptacle 232. Here, the plug 218 relative to the socket (not shown means) initially be aligned such that the second abutment surface 236 sections contacted the first abutment surface 234. In other words, an operative connection between plug 218 and protective plate 226 is made during the insertion process. Thus, preferably, a first contact by the insertion in the region of the stop edge 237 of the second stop surface 236 and the abutment portion 235 of the first abutment surface 234 take place. Due to the further insertion of the plug 218 in the insertion direction 238 is due to the formation of the first stop surface 234 as a slope, a displacement of the protective plate 226 in the displacement direction 240 causes in particular a

Force deflection from the insertion direction 238 in the direction of displacement 240 by the illustrated interaction of plug 218 and socket 216

provided. The abutment surfaces 234, 236 can be matched to one another such that a certain (desired) displacement path 1 is achieved. In other words, the female guide module 230 is particularly so on the

Plug guide module 232 tuned that the protective plate 226 (exactly) so far in the direction of displacement 240 is displaced by the insertion of the plug 218 that the contact openings 224 are accessible through the openings 228 of the protective plate In particular, the contact openings 224 are so accessible or released that the second contacts 222 can be inserted or used in the first contacts. This connected state is shown here in FIG. 2b.

It is understood that the force exerted by the insertion of the plug 218 must exceed the force exerted by the return element 242 force. It is further understood that for effecting the displacement of the protective plate 226 in FIG

Displacement direction 240 of the plug 218 during insertion (almost) no shift in the direction of displacement 240 may perform. Appropriate (not shown) fixing means, such as stop surfaces, which prevent a corresponding movement, in the charging arrangement and / or the charging connector be provided. Finally, it is understood that according to other variants of the application other forms of projections, recordings, etc. may be provided.

In a separation of the plug 218 from the socket 216, the plug 218 is separated from the selbigen in particular by a manual execution of the socket 216. The arranged return element 242 causes an automatic closure of the contact openings 224th

FIG. 3a shows a schematic plan view of an exemplary embodiment of a socket 316 according to the present application. The female connector 316 shown is in particular a component of an electrical according to the application

Charging connector (e.g., as shown in Figures 2a and 2b). As can be seen, the illustrated receptacle 316 has a plurality (nine in the present case) of FIG

Contact openings 324 a corresponding number of first contacts 320.

The contact openings 324 are all in the same plane, which runs in particular parallel to a displacement plane. Further, in the present case, the outer shape of the

Plug socket 316 formed by way of example rectangular. The contact opening 324 with the largest diameter compared to the eight others shown

Contact openings 324 has a diameter of d _max .

FIG. 3b shows a schematic plan view of an embodiment of a protective plate 326 for a socket 316. The substantially planar

formed protective plate 326 has a plurality of openings 328 (nine in the present case), which correspond to the contact openings 324 of the socket 316 in the manner previously described. It is understood that the respective diameter of the openings 328 may preferably be formed substantially equal to or alternatively greater than the respective diameter of the contact openings 324. Further, the top of the guard plate 326 has a projection 330 (previously described) with a stopper surface 334 (previously described). Figures 3c and 3d show the previously described embodiments of a socket 316 and a corresponding protective plate 326 schematically in an assembled state. For a better overview was on the

Presentation of a plug omitted. In particular, Figure 3c shows a schematic plan view of a

Embodiment, in which on the socket 316 of Figure 3a a

Protective plate 324 is arranged according to Figure 3b in a released position. In other words, in this position, all the contact openings 324 of the first contacts 320 are accessible through the openings 328 of the protective plate 326. As a result, second contacts (not shown) can be inserted into the contact openings 324.

FIG. 3d shows a schematic top view of an exemplary embodiment in which a protective plate 326 according to FIG. 3b is arranged in a closed position on the socket 316 according to FIG. 3a. In other words, all are

Contact openings 324 of the first contacts 320 covered by the protective plate 326 or closed. A high level of security can be provided thereby.

In order to ensure that all the contact openings 324 of the first contacts 320 in an unconnected state are completely covered by the protection plate 326 in the closed position, it is necessary that the displacement path 1 is greater than the maximum diameter d _max . It is understood that this

may be provided in particular for the case when the respective diameters of the openings 328 of the protective plate 326 substantially correspond to the respectively corresponding diameters of the contact openings 324. In the event that the

Diameter of the openings 328 are greater than the diameter of the contact openings 324, a corresponding increase in the displacement path 1 is required (by a corresponding configuration of the guide modules, such as the stop surfaces).
