Description

The present invention relates to a plug-in system according to the preamble of claim 1 and a plug according to the preamble of claim 31.

An inventive plug-in system or a plug according to the invention are used to produce an electrical plug-in connection by plugging together two connectors of the plug-in system or by plugging the plug into a socket or socket complementary thereto.

A "plug connection" in the sense of the present invention is a connection between a first connector and a second connector, wherein the first and the second connector are electrically connectable or connected to each other, that the connectors are inserted into each other. Preferably, at least one of the connectors has at least one contact pin and the other connector has at least one opening for the contact pin. The connectors may be formed, for example, as a plug and socket or socket.

A "plug" in the sense of the present invention is preferably a connector for establishing an electrical connection with at least one, preferably two or more, contact pins. However, a plug may have openings for contact pins of a complementary connector in addition to the contact pins.

A "socket" in the context of the present invention is a complementary to a plug means for producing the electrical connector. Accordingly, a socket has at least one, preferably two or more, openings for the contact pin or the contact pins of the complementary connector. In particular, a socket may be designed as a socket and / or be arranged or recessed in a wall.

A "plug-in system" in the context of the present invention is a system with two or more connectors for producing an electrical plug connection, wherein the connectors are complementary to each other and can be electrically connected to each other by plugging.

In particular, when using protective contact plugs, also called Schuko plug, there is often the problem that they sit relatively firmly in the socket, so that removal of the plug from the socket is possible only with great effort. This is particularly problematic for weak users such as ill or elderly people. Furthermore, the high force required can also be due to the fact that the socket or the plug is located in a hard to reach place.

It is an object of the present invention to provide a solution in which the release of an electrical connector is facilitated, in which a particularly simple structure is realized, and / or in the operating error when releasing the connector can be reliably avoided.

The above object is achieved by a plug-in system according to claim 1 or a plug according to claim 31. Advantageous developments are the subject of the dependent claims.

As already explained at the beginning, a plug connection is a particularly electrical connection between a first connector and a second connector. A connector according to the present invention is preferably a plug, a socket or socket and / or an adapter.

In the present invention, one of the connectors, in particular the connector, which is referred to below primarily as the first connector, is designed as a plug. The features of the first connector described below are therefore preferably also features of the (inventive) connector.

An inventive plug-in system has a first connector and a second connector, wherein an electrical plug connection can be produced between the connectors.

The connector according to the invention can form part of the plug-in system according to the invention.

The plug-in system according to the invention or the plug according to the invention has a force reduction device for reducing the force required to release the plug connection between the connectors. Preferably, by the force reduction means a release of the connector between the connectors, in particular a movement apart of the connectors, facilitated. Particularly preferred can be facilitated by the force reduction device pulling out a plug from a power outlet.

The force reduction device preferably has a mechanism that defines a first stable state and a second stable state of the force reduction device. The stable conditions ensure simple and safe operation of the force reduction device. In addition, the stable states prevent the two connectors from being disconnected, if not desired.

Hereinafter, the first stable state and the second stable state are mostly abbreviated as the first state and the second state.

Furthermore, the force reduction device has a preferably axially movable actuating part or a plurality of actuating parts. Preferably, an operation or actuation of the force reduction device takes place by means of the actuating part or the actuating parts. Particularly preferably, the force reduction device is actuated exclusively via the actuating part or the actuating parts.

According to a first aspect of the present invention, the first connector, the force reduction device, wherein the actuating part is preferably formed at least substantially bolt-like. The actuating part is preferably arranged on the first connector, that in a position of the connectors to each other, starting from which the connector is produced by axially merging the connectors, both in the first and in the second state, the actuating member axially toward the second Connector protrudes from the first connector. Furthermore, the actuating part is preferably arranged on the first connector such that in this position, both in the first and in the second state, at least one axial end side of the actuating part is arranged between an end face of the first connector and an end face of the second connector. This allows a simple structure.

Alternatively or additionally, the actuating part or the actuating parts are arranged in the second connector in such a way that the actuating part or the actuating parts are simultaneously actuated by two contact pins of the first connector during production of the plug connection, wherein the force reducing device is designed to that by a, preferably at least substantially complete, first movement of the first connector in the insertion direction when producing the plug connection, the force reduction device is transferred to the first state and that by a, preferably at least substantially complete, renewed movement in the insertion direction, the force reduction means the first stable state leaves. In this way, a simple and safe operation of the plug-in system or the force reduction device is guaranteed or supported. In particular, the force reduction device can thus be reliably transferred to the first state. Furthermore, such a one-handed operation is possible.

In other words, the actuating part or the actuating parts are arranged in the second connector such that the actuating part or the actuating parts are simultaneously actuated in a production of the connector by at least two contact pins of the first connector or, wherein the force reducing means is adapted to that by a first movement of the first connector via a relative position of the connectors, which corresponds to the first stable state, out in the plug-in direction in the manufacture of the connector, the force reducing means is converted to the first state and that by a renewed movement of the first connector on the relative position of the connectors , which corresponds to the first stable state, out in the insertion direction, the force reducing device leaves the first stable state.

The force reduction device is preferably designed such that the force reduction device is transferred to the first state by a first movement of the first connector in the insertion direction during the production of the plug connection and that the force reduction device leaves the first stable state by a renewed movement in the insertion direction.

By leaving the first stable state, the force reducer is triggered, thereby exerting a force that forces the connectors apart to achieve or facilitate disconnection of the connector.

Preferably, between the first movement and renewed movement of the first connector in the insertion direction, a slight movement of the first connector against the insertion direction, whereby the renewed movement in the insertion direction and thereby leaving the first stable state is possible.

In particular, therefore, a movement of the first connector in the same direction is required both for transferring into the first state and for leaving the first state. This is conducive to easy operation. Furthermore, such a one-handed operation is possible.

The force reduction device is preferably designed to reduce the force required to release the connector by moving the connectors apart. In this way, the release of the connector is facilitated. For this purpose, the force reduction device is preferably designed to effect, starting from the first stable state or when leaving the first stable state, a force which forces the connectors apart. This force can be generated or stored in the production of the connector. In particular, will a tensioning means, in particular a spring, stretched, the spring force causes the release of the connector is facilitated.

The force reduction device is preferably designed to exert a force upon release of the plug connection to the connector, which does not have the force reduction device, so that the connectors are moved apart and / or separated from one another.

In particular, the actuating part is adapted to press when releasing the connector against one of the connectors, in particular against the opposite side of the actuating member. A disassembly of the connectors is preferably facilitated or supported in this way.

Preferably, the first stable state of the force reduction device corresponds to a first stable axial position of the operating part and the second stable state of the force reduction device corresponds to a second stable axial position of the actuating part.

Hereinafter, the first stable position and the second stable position are mostly abbreviated as the first position and the second position.

The actuating part preferably has two end positions, between which the actuating part is movable. A movement of the actuating part from the second stable position into the first end position preferably results in reaching the first stable position. In this case, the first stable position is preferably a position of the actuating part, which is offset relative to the insertion direction, preferably slightly, in relation to the first end position. In the first stable position of the actuating part or in the first stable state, the connectors therefore preferably have a spacing, preferably a slight one, in the sense that a movement of the first connector in the direction of insertion opposite the second connector is made possible.

To achieve the first stable position, the actuating part is preferably moved beyond the axial position, which corresponds to the first stable axial position, in the insertion direction and with slight movement in the opposite direction, the actuating member enters the first stable axial position. As a result, the connectors are or are correspondingly slightly spaced from each other.

By renewed movement of the actuating part or first connector in the insertion direction, a movement of the actuating part in the direction and / or up to the second stable axial position is released. As a result, the actuating part acts in such a way that a separation of the connector is supported. In this case, the connectors are preferably pressed apart. The separation of the electrical connector is accompanied by a separation of the electrical connection between the connectors. Under release or disconnection of the connector, the actuating member then passes into the second end position, which preferably corresponds to the second stable axial position.

A slight movement, a slight offset or slight distance is for example less than 3 mm, preferably less than 2 mm, in particular less than 1.5 mm. Slightly, a movement, an offset or a distance between the connectors is preferably when an electrical contact surface between the connectors, which is not changed at fully or to a final stop made connector despite the slight distance is or will not.

The activation of the force reduction device is preferably carried out in that the connectors, which were previously moved slightly away from the end stop, leaving the contact area between contact elements and contact pins unchanged, are again approximated to one another. For this purpose, the first connector is again moved in the insertion direction.

This makes it possible while maintaining a low-impedance or proper electrical connection to trigger the force reduction device by re-movement of the first connector in the insertion direction, so to cause the force reduction means the first stable state and the actuating member leaves the first stable axial position and movement of the Operating part in the direction of the second stable axial position applies a force for separating the connector. A corresponding force preferably also brings the force reduction device between the end stop and the first stable state, but not beyond the first axial position corresponding thereto, so that only the slightest distance results here.

"End stop" in this context preferably means that the connector is made and the connectors are supported on the front side or in the insertion direction to each other, abut each other or block further movement in the direction of insertion. In the end stop, the first connector can therefore no longer approach the second connector. The end stop of the connector or connectors corresponds to this preferably the first end position of the actuating element.

In particular, contact pins of a connector in manufactured connector to contact elements of the other connector and the case generated surface in which the pins directly abut the contact elements and thus is relevant for a contact resistance, is completely up to a terminal made a connector (without the slightest distance) and at the slightest distance the same.

If, starting from the end stop movement of the connectors apart in the first stable state, so a contact surface of contact pins with complementary or complementary contact elements is not changed. This movement to reach the first stable position is preferably caused by the force reduction device.

In fact, it is the case that contact pins generally have a contact region with contact elements complementary thereto. Although this contact area or the surface thereof changes during the manufacture and release of the connector, but not with insignificant or minor movements of the connectors to each other in at least substantially completely interconnected connectors, while the electrical connection is made. This is preferably used to be able to effect activation of the force reduction device.

Particularly preferably, a transition of the force reduction device from the first state to the second state by a movement of the actuating part from the first position to the second position and / or corresponds to the transition from the first state to the second state of movement of the actuating part from the first position in the second position.

The force reduction device is preferably designed and / or arranged such that upon manufacture and / or release of the plug connection actuation of the force reduction device and / or movement of the actuating part, in particular relative to the housing, takes place in that the connectors relative to each other in the axial direction to be moved. In particular, the actuating part or the force reduction device is actuated or moved by one of the connectors. This offers the advantage that a manual operation of the force reduction device is not required, so that the operation is facilitated. Furthermore, it is thus possible to produce and / or release the plug connection one-handedly.

The force reduction device is preferably designed and / or arranged such that upon connection of the connectors of the operating part opposite connector acts on the actuating part such that the actuating member moves axially, in particular in a housing of the force reduction device is inserted. In particular, in this way an automatic actuation of the force reduction device when connecting the connectors is made possible, so that a separate manual operation of the force reduction device is not required. This in turn is conducive to easy operation.

The force reduction device is preferably designed to exert a force upon release of the plug connection on the connector opposite the force reduction device or on the connector which does not have the force reduction device, in particular so that the connectors are moved apart and / or separated from one another. In this way, a release of the connector or separating or moving apart of the connectors is supported.

Preferably, the actuating member is adapted to press upon release of the connector against one of the connectors, in particular against the connector opposite the actuator, in particular so that a movement apart of the connectors is facilitated or supported. Preferably, therefore, the force required to move apart the connectors is reduced by the fact that the actuating part presses against one of the connectors or pushes the connectors apart.

The force reducer is preferably configured to automatically transition the force reducer to the second state when the force reducer exits the first stable state or when the force reducer is not fully transitioned to the first state. This facilitates operation of the plug-in system and / or plug or force reducer since a user or operator immediately notices the automatic transition to the second state if the force reducer has not been transferred to the first state as desired.

The force reduction device is preferably designed to transition to the first stable state when the actuating part is at least substantially complete for a first time moved in the direction of actuation, preferably inserted into a housing of the force reduction device, is. This allows a simple and intuitive procedure when producing a plug connection, since the connection of the connectors can take place in that the connectors are inserted or inserted at least substantially completely into each other. After such an at least substantially complete movement, the force reduction device preferably automatically transitions into the first stable state. In particular, when the connection between the connectors is made, no separate actuation of the force reduction device is necessary in addition to connecting the connectors by plugging in order to convert the force reduction device into the first stable state.

Further, the force reduction means is preferably adapted to leave the first stable state and / or to go into the second stable state when the actuating part a, preferably on the first time (directly) subsequent and / or starting from the first stable position, second time completely moved in the direction of actuation, preferably inserted into the housing, is. In this way, unwanted actuations of the force reduction device can be avoided or an undesirable transition to the second stable state can be avoided, as to a renewed movement in the direction of actuation is required. Thus, it is particularly excluded that by pulling on a plug with a force reducing means a transition to the second stable state and thus ejection of the plug is induced from a power outlet.

The force reduction device is preferably designed such that

• - By at least substantially complete movement of the actuating part in the direction of actuation, the force reduction device is displaceable in the first state, and / or
• - After the at least substantially complete movement in the direction of actuation, the actuating member is first moved back by means of a clamping element such as a spring against the operating direction a short distance and is then preferably held positively in the first position, so that the force reduction device is in the first state, and / or
• is effected by a renewed at least substantially complete insertion of the actuating part starting from the first state, that the actuating part is moved by means of the clamping element or the spring counter to the actuating direction, and / or
• - By the movement of the actuating part by means of the clamping element or the spring against the operating direction starting from the first state, the force required to release the connector is reduced.

The force reduction device can be arranged completely inside the second connector and / or the second connector can have openings for contact pins of the first connector, wherein the actuating part can be actuated only through the openings. In this way, a - intentional or unintentional - manual actuation of the force reduction device or the operating part is avoided. Furthermore, the safety of operation of the force reducing device is increased since manual operation of the force reducing device is neither possible nor necessary, and thus a user does not have to grasp a socket to operate or operate the force reducing device. Consequently, there is also no risk of electric shock in the operation of the force reduction device.

The following is on the mechanism 5 discussed in more detail. Details of the mechanism 5 are in 9 shown. The explanations to the mechanism 5 preferably apply to all embodiments.

Preferably, the mechanism 5 a feather 14 on. The feather 14 is preferably designed as a compression spring and / or adapted to the actuating part 6 to move towards the second position and / or the actuating part 6 to bias toward the second position. Instead of the spring 14 However, here are other solutions, in particular clamping means conceivable, with which the actuating part 6 can be moved.

Preferably, the spring 14 stretched and / or compressed in the first position. In the second position is the spring 14 preferably less tensioned or compressed than in the first position. It is also possible that the spring 14 in the second position is not curious. However, it is preferred that the spring 14 is biased in the second position, since so the actuating part 6 by means of the spring 14 can be kept better or stable in the second position.

The force reduction device 4 is preferably designed so that after a (first) - explained above - at least substantially complete movement in the direction of actuation, the actuating part 6 first by means of the spring 14 against the direction of actuation B is moved back a short distance and then held positively in the first position. In particular, the force reduction device is located 4 that is, in the first state after the operating part 6 from the spring 14 a short distance against the direction of actuation B was moved back.

The actuating part 6 preferably has two end positions. A first end position is preferably assigned to the first position, while the second end position preferably corresponds to the second position.

The first end position is characterized in that in this the connectors 1A . 1B are completely inserted into each other, so that they abut each other frontally. Alternatively or additionally, the actuating part 6 in the first end position at least substantially completely in the housing 8th sunk or flush with the housing 8th from.

The first end position is preferably located on a side of the first position facing away from the second position or second end position. In other words, the actuating part arrives 6 starting from the second position by movement in the direction of actuation B to a position corresponding to the first position, over to the first end position.

Starting from the first end position, the actuating part 6 preferably automatically, in particular by the spring 14 or any other drive or tensioning element is moved counter to the actuating direction in the first position. Here, the actuating part acts 6 preferably on the (other) connector 1A . 1B So on the connector 1A . 1B , the force reducer 4 does not have, so the connectors 1A . 1B slightly opposite to the insertion direction e or moved away from each other.

In the first position are the connectors 1A . 1B so slightly spaced apart. This may be a distance of less than 3 mm, preferably less than 2 mm, in particular less than 1.5 mm or 1 mm. In this way, a reliable contact or electrical connection can be realized, although the first connector 1A due to the small distance to the second connector 1B then again in the insertion direction e is movable, namely the previously described slight distance.

Due to the small distance, the force reduction device 4 get out of the first stable position, creating a force on the other of the connectors 1A . 1B , the force reducer 4 does not have, by the force reduction device 4 is feasible, so that a disconnection of the connector or the connectors 1A . 1B by the force reduction device 4 is supported.

The force reduction device 4 is preferably designed so that is effected by a renewed at least substantially completely insertion of the actuating part, in particular starting from the first state, that the actuating part 6 by means of the spring 14 against the direction of actuation B is moved. In particular, a movement of the actuating part takes place 6 by means of the spring 14 automatically and / or by the fact that the spring 14 in the first position of the operating part 6 or in the first state of the force reduction device 4 compressed and / or curious.

The movement of the operating part 6 by means of the spring 14 against the direction of actuation B , in particular starting from the first state or the first position, preferably takes place until the actuating part 6 is in the second position.

The force reduction device 4 is preferably adapted to that by the movement of the actuating part 6 by means of the spring 14 against the direction of actuation B starting from the first state, the force required to release the connector is reduced.

In particular, the force that results in the actuating part 6 when releasing the connector on one of the connectors 1A . 1B or the connectors 1A . 1B exerts, from the spring force of the tensioned or compressed spring 14 ,

The mechanism 5 preferably has a preferably hook-like form-fitting element 15 and a guide 16 for guiding the positive-locking element 15 on.

The leadership 16 is preferably asymmetrically shaped and / or asymmetrical in the actuating part 6 arranged, in particular in 9 is recognizable.

The feather 14 , the leadership 16 and the positive-locking element 15 preferably cooperate in such a way that in two successive movements of the operating part 6 in the same direction, with the operating part 6 each at least substantially completely in the direction of actuation B is moved, the actuating part 6 is held in a form-fitting manner after the first movement in the first position or engages and reaches the second position after the second movement.

Between the movements of the operating part 6 in the direction of actuation B or the same direction is preferably carried out an opposite movement, whereby the actuating part 6 in the first position. This opposite or opposite to the direction of actuation B directed movement is preferably by the spring 14 or any other clamping device or drive device caused and / or makes it possible that the actuating part 6 starting from the first position again in the direction of actuation B can be moved. Through this second movement in the Actuation direction causes the mechanism 5 by an asymmetry, preferably in cooperation with the positive-locking element 15 in that the first position is left and the force of the spring 14 or another clamping element or drive element against the insertion direction e on the first connector 1A or the connectors 1A . 1B divergence becomes. As a result, a disconnection of the connector is facilitated.

The above-mentioned "at least substantially complete" movement of the operating part 6 preferably takes place so far that the positive-locking element 15 so far in the lead 16 It is that when releasing the operating part 6 is not moved back the same way, but is moved on until it is form-fitting in the lead 16 is held or locks. An at least substantially complete movement is thus a movement in which this further movement instead of a return movement of the positive-locking element 15 he follows.

The actuating part 6 is preferably adapted to be by the force of the spring 14 out of the case 8th is pushed out and thereby reduces the force required to disconnect the connector is reduced. In the illustrated example, the actuating part for this purpose a stop 17 for the spring 14 on, over which the spring 14 on the actuating part 6 against the direction of actuation B acts. This stop 17 is formed in the illustrated example as a particular ring-like projection. However, it may also be a step or other structure for supporting the spring 14 act.

Furthermore, the stop defines 17 or another constructional measure, such as a step of the operating part 6 preferably a (second) end position of the actuating part 6 im out of the case 8th pushed out state, such as in 8th shown. In this position of the operating part 6 can the stop 17 or an appropriate measure cause the operating part 6 through the spring 14 not further out of the case 8th is postponed. At the stop 17 It can be an adjustable stop 17 act. For example, the stop 17 by turning the operating part 6 be adjustable. Here, however, other solutions are possible.

The feather 14 is preferably configured by biasing the operating part 6 in the direction of the second position to cause a reduction in force when releasing the connector. In one variant is the spring 14 designed as Evolutfeder. This allows a compact design. In the illustration example is a coil spring.
