Description

The invention relates to a socket with a housing and a cover arranged on the housing with a flat extension.

Sockets are well known in the art and are used, for example, in the field of e-mobility applications on an electric vehicle and / or on a charging device to make an electrical connection to the socket for "refueling" of the electric car by means of a cable connector.

In other words, therefore, the electric car for "refueling" is connected to the charging station via a cable that can be firmly connected on one side, so either to the electric car or to the charging station, but in any case on the other side pluggable. To meet this pluggability, the aforementioned sockets have been developed, which are usually closed with a lid so that the provided in the socket electrical contacts are protected against the ingress of moisture or dirt.

In order to design the protection as efficiently as possible, the lid is often subjected to spring force, so that the lid strives in its closed position. However, this means, on the other hand, that for connecting the cable plug to the socket, ie for inserting the cable plug into the socket, the lid must first be opened manually, so with a first hand, and then must be held in the open position with the first hand so that then with the second hand or by a second person the Cable plug can be inserted into the thus opened socket.

However, as can easily be seen, this procedure is very complex, since two hands or even two persons are needed.

Based on this situation, it is the object of the invention to provide a socket with a lid into which a cable connector is particularly easy to insert, so that in particular an operation is possible only with a single hand.

The object is achieved according to the invention by the subject matter of the independent claim. Advantageous embodiments of the invention are specified in the subclaims.

Accordingly, the object of the invention is achieved by a socket having a housing and a lid arranged on the housing with a planar extension, wherein the lid between an open position and a closed position about a pivot axis, the housing has a peripheral edge, to in that the lid abuts in the closed position with its inside to cover an area lying within the edge, and the lid has a contour integrally formed with the lid, wherein in the closed position the contour lies outside the rim, the contour of the housing Direction of the planar extension at least partially surmounted, and the contour forms a sliding surface, which extends from a tip of the contour, in the direction of the flat extent of the lid and opposite to the lid is arranged, extends toward the housing and towards the inside of the lid.

The invention thus allows a comfortable opening of the lid in "one-handed operation" in that a plug which is to be plugged into the socket, is attached to the contour, so that then by pivoting the plug, the lid can be opened, namely in particular by that the contour with its sliding surface slides over the plug, so that finally in the opened position of the lid, the plug can be plugged into the socket. Because by the provision of the sliding surface, a sliding of the contour over typically provided on the plug edges and elevations is made possible, so that at the end of the pivoting movement of the plug, the plug can be inserted as previously carried out in the socket. The socket according to the invention thus enables a much more comfortable and easier plugging a plug into the socket with respect to the known from the prior art embodiments.

The housing and / or the cover can in principle be made of any material, such as a plastic. Further, the housing may be designed for insertion and / or fastening in an opening of a wall and be designed to be multi-part, so are fastened with a first housing part on the outside of the wall and with a second housing part on the inside of the wall. In the context of the invention, a planar extension of the cover is preferably to be understood to mean a planar and / or curved extension, wherein in the closed position, preferably, the cover extends completely within the housing particularly preferably provided electrical plug contacts and / or a mating face completely against ingress of moisture or dirt closes. For this purpose, furthermore, the cover and / or the peripheral edge can be configured with a seal, which is preferably also designed to be circumferential, for example as an O-ring seal.

Furthermore, it is preferred in this context that the peripheral edge forms a circular, substantially circular or polygonal opening into which a plug corresponding to the socket for establishing an electrical connection between the socket and the plug can be inserted. In this respect, an open position is to be understood in particular as the position in which the plug can be inserted into the socket for establishing the electrical connection.

Further, it is preferred that the lid is pivotally mounted at a first end to the housing, for example via a pivot axis, while particularly preferably the contour is arranged on the second end opposite the first end of the lid. More preferably, the lid and the contour each have an outer side, which are arranged corresponding to each other, very particularly preferably linearly merge into one another. The tip is preferably arranged at the farthest from the cover and / or the pivot axis and at the outermost end, so for example. In the direction of the planar extension of the lid of the pivot axis in the direction of the contour and opposite to the Verchwenkachse. More preferably, the contour projects beyond the edge in the insertion direction or in a direction of extension perpendicular to the inside of the lid and away from the lid. Also preferably, the lid completely closes the peripheral edge of the housing in the closed position, wherein the contour on the lid is preferably arranged such that the contour is in the closed position outside the edge, in other words in plan view of the socket, ie in the insertion of the plug into the socket, the housing preferably at least partially protrudes perpendicular to the direction of insertion, so at least partially "next to" the housing comes to rest. In this case, the contour is preferably arranged such that it extends away from the second end of the lid in the opposite direction to the axis of rotation of the lid and in the above plan view to a part "on" the housing and is located to another part "next to" the housing , Typically, the aforementioned pivot axis is arranged on the "top" of the socket, so that the contour comes to rest on the "bottom" of the socket, at least in the closed position of the lid.

In the context of the invention, a sliding surface is understood to be any surface which makes it possible to slide a plug over this surface, so that the cover can be pivoted from the closed position into the open position by a pivoting movement of the plug. Most preferably, the sliding surface extends linear, curved or curved from the top of the contour in the direction of the housing and perpendicular to the inside of the lid. This means that the sliding surface particularly preferably extends in a direction which lies at an angle, preferably 45 °, to the insertion direction and / or to the planar extent of the cover. More preferably, the extension of the sliding surface begins directly at the top of the contour, so preferably at the point of the cover farthest from the pivot axis of the lid.

According to a particularly preferred embodiment, the tip has a bending radius of ≥ 1 mm and ≦ 5 mm, preferably 3 mm, wherein the center of the bending radius lies on an axis parallel to the pivot axis of the lid. By providing a bending radius, the "sliding" of the plug can be further improved, because it can be achieved even at a very acute angle between the lid and the plug that the lid does not hang on a step of the plug.

According to a further embodiment, it is advantageously preferred that the sliding surface in the closed position lies outside the edge. Preferably, the sliding surface is in the closed position in plan view of the socket in the insertion completely outside the housing or "next to" the housing. For the fact that the contour partially or preferably completely or partially in the closed position "next to" the housing is arranged, so the housing protrudes perpendicular to the insertion, the tip of a plug can be attached to the sliding surface, so then by Swiveling movement of the plug, the lid is "levered". When "levering" the sliding surface slides preferably on the housing of the plug. In contrast, lids of known from the prior art sockets are designed such that they flush with the peripheral edge, so do not protrude in plan view in the insertion direction with the lid closed to the socket on the housing.

According to a further preferred embodiment, it is provided that the sliding surface extends in a direction which forms an angle ≥ 25 ° and ≦ 65 °, preferably ≥ 35 ° and ≦ 55 °, and very particularly 45 ° to the planar extent of the inside of the lid , Especially an angle of 45 ° has been found to be particularly advantageous to allow the opening of a lid designed according to the invention particularly simple in "one-handed operation".

In principle, the sliding surface can extend over any distance from the top of the contour. However, it is particularly preferred and advantageous if the sliding surface extends in the closed position up to the housing. Such a configuration allows on the one hand a particularly simple opening of the lid and on the other hand a sufficiently large sliding surface on which the plug can slide during the opening movement.

According to another preferred embodiment, it is provided that the contour for forming the sliding surface extends perpendicular to the planar extension of the lid. In other words, it is therefore preferred that the contour extends in the direction of the housing, provided that the lid is in its closed position. Since, according to this preferred embodiment, the contour does not extend straight away from the outside of the lid, the danger can be avoided that unintentional opening of the lid due to "snagging" on the contour is avoided.

In principle, according to a further preferred embodiment, a plurality of contours may also be provided which are parallel to each other in a planar manner extend and each extend in parallel from the top of the contour in an extension direction towards the housing or respectively form a sliding surface which extend in a parallel manner from the tip in the closed position towards the housing and perpendicular to the inside of the lid. Between the contours, which may for example be designed like a triangle, a gap may be present, so that a particularly material-saving design is made possible. Most preferably, the contour or the plurality of contours is hosed integrally with the lid.

In addition to the aforementioned triangular shape of the contour is very particularly preferred that the contour forms a nose-like shape in its extension perpendicular to the flat extent of the lid. In addition, any form which allows the aforesaid sliding of the plug to open the lid is advantageous.

According to yet another preferred embodiment, it is provided that the housing has a recess into which the contour engages correspondingly in the closed state. It is further preferred that the recess is arranged outside the edge. According to a still further preferred embodiment it is provided that the socket has a plug insert, for example, with electrical contacts, wherein the plug insert is disposed within the edge. Furthermore, the plug insert may have a mating face into which a plug corresponding to the socket can be inserted.

The invention will be explained in more detail below with reference to the appended drawing with reference to a preferred embodiment.

In the FIGS. 1 to 5 an outlet according to a preferred embodiment of the invention is shown. The socket is for making an electrical connection to a plug 1, shown in FIG Fig. 1 such as Fig. 4 and Fig. 5 , designed.

The socket has a housing 2, which in the present case is designed in two parts, that is inserted in an opening of a wall 3, so that a first part of the housing 2, hereinafter referred to as housing 2, is arranged on one side of the wall 3 and a second Part 4 of the housing 2 is arranged on the other opposite side of the wall.

On the housing 2, a lid 5 is pivotally arranged via a pivot axis 6. The lid 5 is between a closed position shown in FIG Fig. 4 , and an open position, shown in all other figures, pivotable. In this respect, the open position basically denotes any other position that does not correspond to the closed position, but preferably the open position is the position at which the plug 1 can be inserted into the socket.

On the housing 2, a circumferential edge 7 is provided, which is covered in the closed position of the lid 5 by the cover 5. By providing a seal 8, which is also circumferentially arranged on the edge 7, it is ensured that in the closed position of the cover 5 no moisture and / or other dirt can penetrate into the opening 9 of the housing 2 formed by the peripheral edge 7 , In order for the lid 5 to remain in its closed position, a spring, not shown, is provided, which is configured and arranged such that the lid 5 strives to its closed position.

In the opening 9 and bordered by the edge 7, a plug insert 10 is provided, which has a plurality of electrical contacts, so that the electrical contacts are protected in the closed position of the lid 5 against external influences.

Integral with the cover is now a contour 11 is provided, which at the pivot axis to the sixth opposite end of the lid 5 is arranged and extends away from the lid 5. The lid 5 has, as can be seen from the figures, a planar extension, wherein, as shown Fig. 4 it can be seen, the outside of the lid 5, so the side of the lid 5, which is not facing the plug face 10 in the closed position, is rounded. How to do that Fig. 4 further seen, go the outer sides of the lid 5 and the contour 11 linear into one another. In the closed position, the cover 5 is in contact with the edge 7.

The contour 11 now has, as for example Fig. 2 or Fig. 3 can be seen, a tip 12, which is in the closed position of the lid 5 at the outer end of the contour 11, so farthest from the housing 2, as seen from Fig. 4 is apparent. In the closed position of the lid 5, the contour 11 is outside the edge 7 and engages in a provided on the housing 2 recess 13 a.

As further out Fig. 4 can be seen, the contour 11 projects beyond the housing 2 in the closed position of the lid 5 at least partially, so located in the direction of the planar extension of the lid 5 of the pivot axis 6 in the direction of the contour 11 in a free area outside the housing 2 and outside In other words, the contour 11 projects beyond the housing 2 at least partially in a direction perpendicular to the insertion direction 14 of the plug 1 into the socket.

On the contour 11, a sliding surface 15 is further formed, which extends from the top 12 of the contour 11 to the housing 2 and perpendicular to the inside of the lid 5, namely in this case at an angle of 45 ° to the flat extent of the inside of the lid 5 and to the insertion 14. The sliding surface 15 is, as seen from Fig. 4 can be seen, completely outside the edge 7 and adjacent to the housing. 2

The tip 12 has a bending radius which is 3 mm, wherein the center or the center line of the bending radius lies on an axis parallel to the pivot axis 6 of the lid 5. From the in Fig. 3 illustrated view of the socket "from below" can be seen that two contours 11 are provided, which extend nose-like or triangular flat from the inside of the lid 5 and parallel to each other. Between the two contours 11, a gap 16 is arranged. Both contours 11 each have a jaw surface 15, also called drainage surface, which widens in a parallel manner from the tip 12 in the aforementioned angle of 45 ° to the housing 2.

To be able to plug the plug 1 into the socket, as in Fig. 1 indicated, the plug 1 is with its plug-in portion 17 at the top 12, the aforementioned bending radius, recognized, as in Fig. 4 seen. In this illustration, the lid 5 is still in its closed position, but this by a pivoting of the plug 1, as in Fig. 5 indicated by arrow 18, is pivotable in its open position.

For this purpose, the region 17 of the plug 1, which encloses the plug contacts of the plug, slides over the sliding surface 15, so that an opening of the lid 5 in "one-hand operation" is possible. Because of the provision of the sliding surface 15 and the contour 11 provided on the connector 1 edges 19 can be overcome easily because of the Providing the sliding surface 15, the tip 12 of the lid 5 does not "hang" on the edge 19. For this purpose, the contour 11 is in particular designed such that it is "higher" than the edge 19 to be overcome.

By providing the bending radius at the top 12 is further achieved that even at an acute angle between the lid 8 and the plug 1, the lid 8 does not hang on the edge 19, but the edge 19 during insertion of the plug 1 into the socket easily can overcome.
