Description

Socket and plug connection

The invention relates to a socket and a

Plug connection, in particular a combined AC / DC socket for applications in electromobility (E-

Mobility) and a plugged into this socket or plug.

In the field of electromobility are different

Charging plug systems for the power supply of electrically operated vehicles known. These serve e.g. for charging on the AC mains (AC) or for fast charging

Direct current (DC). In this case, such sockets are also known, which have both an AC mating face and a DC ^¬ mating face.

To protect the mating faces of a combined AC / DC power outlet from contamination and unauthorized access, the mating faces are often protected with separate protective plugs. The AC stopper usually overlaps the DC stopper. Before a

The appropriate protective plug is removed from the socket and an AC, DC or AC / DC plug can always be plugged into the corresponding plug

Plug face of the socket are inserted. So far, no separate DC plug for a DC charging are common, so that when DC charging always a combined AC / DC plug

is used. Nevertheless, it is of course conceivable that pure DC plugs will also be used in the future.

The problem is that, for a charge with an AC plug zstopfen both the AC-Schut and the DC-Schut zstopfen could be removed from the socket and thus during charging with an AC plug, the high-voltage contacts of the DC socket would be unprotected.

The same applies to the situation during the journey, as in a combined AC / DC socket, due to the

Overlap the AC guard plug over the DC guard, only plug the AC guard over one

electromechanical device is locked. at

A plugged AC guard would not plug one

plugged in DC-Schut zstopfen not recognized, which would have the consequence that the high-voltage contacts of the DC socket would be unprotected while driving.

It is the object of the invention to provide such a socket for e-mobility applications, the one

Safety mechanism for a reliable protection of the high-voltage contacts has.

This object is solved by the subject matter of patent claim 1. Preferred developments are in the

Subclaims specified.

According to the invention, a socket is thus provided, with a first mating face for receiving a first

Plug, a second mating face for receiving a second plug, a first protective plug to protect the first mating face when not plugged first

Plug, a second protective plug to protect the second mating face with not plugged in second connector and a pawl, wherein the pawl between a

Locking position and an unlocking position is pivotally mounted and the pawl executed and

is arranged so that it is not plugged in the first protective plug or not plugged first plug in the blocking position and plugged in the first protective plug or plugged first connector is in the unlocked position and they are in the locked position an insertion of the second connector in the second

Mating face prevented.

In the present case we talked about a first connector and a second connector. These plugs can be separate, ie separate plugs from each other. On the other hand, these two plugs can also act together as a single

be provided combined plug.

It is thus an essential point of the invention to provide a socket with a pawl, wherein the pawl has an unlocking position and a

Has blocking position. In the locked position, the pawl prevents the insertion of the second protection plug or the second plug into the second mating face of

Socket. A release of the pawl of the

Locking position in the unlocking is done by inserting a first protective plug or a first plug into the first mating face of the socket. This means, for example, that only with the insertion of the first protective plug in the first mating face the

Pawl from the locked position into the

Unlocking position transitions and allows insertion of the second protection plug or the second plug in the second mating face. For the embodiment of the socket according to the invention is preferably provided that the pawl is designed and arranged so that by inserting the first

Protective plug or the first plug in the first

Mating face the pawl from the locked position into the Unlocked position is pivoted. It is also envisaged that the pawl so executed and

is arranged by inserting a combined connector for the first mating face and the second

Mating face the pawl is pivoted from the locked position to the unlocked position.

In this context, it is preferably provided that in the blocking position the contour of the pawl protrudes into the first mating face and by inserting the first protective plug or first plug into the first

Mating face the contour of the pawl in the

Unlocked position is pivoted. The term "mating face" is thus at least the area of one

Socket meant to be plugged into the parts of a plug or corresponding to these parts. The

Mating face thus includes besides the actual

Plug contacts, e.g. also a possibly provided the

Plug contacts surrounding circumferential groove into which an optionally provided outer collar of a plug can be inserted.

In this case, a preferred embodiment of the invention further provides that the pawl in the region of the first mating face has a ramp-like contour with a flat angle, so that upon impact of the first protective plug or first plug on the ramp-like contour of

Pawl, the pawl is pivoted from the locked position to the unlocked position. The ramp-like contour of the pawl allows easy pivoting of the pawl upon insertion of the first protective plug or first plug into the first mating face of the

Socket, since the pawl with it, similar to the case of a door lock when hitting the strike plate a door frame, easily recedes. Equally positive, the ramp-like contour of the pawl also affects the insertion of a combined connector for the first

Mating face and the second mating face of the socket off.

Basically, geometry and tilt angle of the

Pawl vary. Thus, the contour of the pawl in the unlocking position does not have to be outside the second mating face, especially not if a corresponding recess is provided in the second plug for the second mating face. In a preferred

Further development of the invention provides that in the blocking position, the contour of the pawl protrudes into the second mating face and in the unlocked position, the contour of the pawl outside the second mating face

Mating face lies.

Furthermore, in a preferred embodiment of

Invention provided that the pawl is rotatably mounted against a force, a magnetic force or preferably against a spring force, and the restoring force, preferably namely the restoring force of the spring, in

Direction of the blocking position acts. In this way it is ensured that the pawl after removal of the first protective plug or first plug or the

combined connector by the force of the

Unlocking position is pivoted to the locked position.

In a preferred embodiment of the invention it is provided that the pawl has a torsion spring and a spring in the axial direction, wherein the restoring force of the torsion spring acts in the direction of the locking position and the restoring force of the spring in the axial direction opposite

Insertion direction of the plug. That way is the Pawl pivotally mounted on the one hand against spring pressure and also allows the spring in the axial direction of an axial displacement of the pawl. It sees a further preferred embodiment of

Invention that the pawl on the

Socket bottom facing side a groove contour

and this groove contour in a groove contour of the socket base to increase the blocking effect of

Pawl engages. In this way, a pivoting of the pawl from the locked position to the unlocked position is prevented in an axial displacement of the pawl in the locked position. The security of manipulation of the pawl is thus increased.

To protect the socket from contamination, the first protective plug protects the first mating face and the second protective plug protects the second mating face. In a preferred embodiment of the invention, it is provided that the contour of the second protective plug the contour of the first

Protective plug overlaps, so that the first protective plug can not be removed from the socket before the second protective plug. In this way, it is ensured that the safety mechanism of the pawl can not be circumvented, since the first protective plug can not be removed without the second protective plug or not independently of the second protective plug from the socket This provides a further preferred embodiment of

Invention that a locking device

is provided, with the second protective plug or

second plug is lockable. In this way, the second protective plug while driving and the second

Plugs are locked during a charging process.

The invention further relates to a plug connection,

comprising a socket having a first mating face for receiving a first plug, a second mating face for receiving a second plug and a pawl, a first protective plug for protecting the first

Plug face when not plugged first connector, a second protective plug to protect the second mating face when not plugged in second connector, a second connector for inclusion in the second mating face at

plugged first protective plug and a combined plug with a first plug for receiving in the first mating face and a second plug for receiving in the second mating face, wherein the contour of the second plug overlaps the contour of the first protective plug, so that the first protective plug not during a charging process with the second plug can be removed from the socket. Thus, a further security is provided which prevents a circumvention of the functional task of the pawl.

In a preferred embodiment of the invention it is provided that the second plug is offset from the first plug of a combined plug in the insertion, so that when inserting the combined plug into a combined socket with a first mating face and a second mating face the pawl by the offset of the blocking position in the

Unlocked position is pivoted. Likewise, to achieve this function according to a preferred

Development of the invention be provided that the two connectors are each provided with an outer collar, wherein the outer collar are offset in the insertion direction to each other and / or different lengths. In this way, it is ensured that even with a combined connector with two mating faces, the pawl can be pivoted from the locked position to the unlocked position.

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

Embodiment of the invention and Fig. 6 is a side view of a combined socket with a first mating face and a second mating face and a combined connector with a first connector and a second connector according to the preferred embodiment of the invention.

From Figure 1 is a socket 1 with a first

Mating face 2 and a second mating face 3, a pawl 4 with a torsion spring 5 and a first

Protective plug 6 and a second protective plug 7 according to a preferred embodiment of the invention

seen. The pawl 4 with the torsion spring 5 is between the first mating face 2 and the second

Plug face 3 is arranged and mounted pivotably between the socket 1 and the plug-8. To protect the contacts from contamination, the first protective plug 6 can be inserted into the first mating face 2 and the second protective plug 7 into the second mating face 3. In Figure 2, the pawl 4 is shown in the locked position. The contour of the pawl 4 protrudes into the first mating face 2 and into the second mating face 3 of the socket 1. The two grooves that surround the actual plug contacts of the two mating faces 2, 3 and in the By inserting a not shown here first protective plug 6 or a first plug 13 in the first mating face 2, the pawl 4 is pivoted from the locked position to the unlocked position.

As can be seen from FIG. 3, by inserting a first protective plug 6 into the first mating face 2, the pawl 4 moves from the blocking position into the locking position

Unlocked pivoted position. In unlocking position of the pawl 4, the second plug 9 can be inserted into the second mating face 3 of the socket 1.

As can further be seen from FIGS. 4 a and 4 b, the pawl 4 has a ramp-like contour 10. The

Ramp-like contour 10 is used for easy pivoting of the pawl 4 from the locking position in the

Unlocking position when inserting the first

Protective plug 6 or the first plug 13 in the first mating face 2, since the pawl thus, similar to the case of a door lock when hitting the strike plate of a door frame, easily recedes. The torsion spring 5 serves to pivot the pawl 4 of the

Unlocking position in the locked position when removing the first protective plug 6 or first connector 13 from the first mating face. 2

Figure 5 is removable, that the contour of the second

Protective plug 7 has a backsplash 11. The

Upstand 11 overlaps the contour of the first

Protective plug 6. The upstand 11 thus prevents removal of the first protective plug 6 from the first

Mating face 2 before not the second protective plug 7 has been removed from the second mating face 3. As can be seen from FIG. 6, the combined plug 12 has a first plug 13 and a second plug 9. The second plug 9 is offset from the first plug 13. As a result, the length offset of the first connector 13 relative to the second connector 9, the first connector 13 is inserted into the first mating face 2 when inserting the combined connector 12 into the socket 1, and thus the pawl 5 from the locked position in the first

Unlocked pivoted position. As a result, the second plug 9 of the combined plug 12 can also be inserted into the second plug face 3. LIST OF REFERENCE NUMBERS
