Description

The invention relates to an arrangement with a plug and a complementary mating connector for making and / or separating a connection of the plug with the mating connector, wherein on the plug a pivotable about an axis lever is arranged. The connection of the plug with the mating connector is separable upon pivoting of the lever in a separation position and / or produced at a pivoting of the lever in a connection position. The plug is in particular a switch module, for example a trigger module for a mating plug designed as a circuit breaker,

Such arrangements of plugs and a complementary mating connectors, in particular of Schulzschaltern with release modules, are used inter alia in switching devices, switches and in particular switches with accessories, for example with adapters. The connection of a plug with a complementary mating connector, each with a plurality of plug contacts, which are connectable to electrical conductors, is usually made or disconnected by plugging or unplugging by hand.

The use of a pivotable lever in the connection of a plug with a complementary mating connector is for example from DE 94 04 295 U1 known and serves to lock the connection as soon as it is made. By pivoting the lever, which is arranged on the plug or on the mating connector, this engages behind with a locking cam a latching pin on the respective other component and thus locks plug and mating connector in the connected position. A disadvantage is that the plugging of the plug depending on the type of connector and, for example, according to the number and design of the plug contacts to be connected requires a considerable effort on the mating connector, which must be applied to make the lock can. In the course of Aufsteckvorgangs on, since the plug contacts increasingly engage, thereby increasing the friction At a force of, for example, 120 Newton in the range of a few millimeters from the fully inserted position when connecting and especially when disconnecting the connector of Hand a significant risk of injury. For example, if a tripping module in a structurally unfavorable position of a switchgear, possibly upside down by a person standing on a ladder, should be removed from a circuit breaker, the sudden release of the connection can easily lead to a fall.

An object of the invention is to facilitate the production of a connection and / or the separation of a connection of a plug with a complementary mating connector, especially in that area in which a particularly high force required for the connection or disconnection.

The object is achieved with regard to the preparation or the separation of the compound in each case by an arrangement according to one of the claims 1 or 2. An arrangement with a combination of the features of claims 1 and 2 represents a preferred embodiment, which solves the problem with respect to the preparation and the separation of the compound. In the remaining subclaims further preferred embodiments and advantageous developments are given, which relate partly to one of the claims 1 or 2, partly to both.

The inventive arrangement with a plug and a complementary mating connector is provided for making and / or separating a connection of the plug with the mating connector, wherein on the plug a pivotable about an axis lever is arranged. It is in the sense of the invention with the names plug and mating connector made no determination to that effect, which is a plug and wherein a plug receptacle. Preferably, the plug is a generally replaceable switch module, in particular a trigger module, which particularly preferably cooperates with a circuit breaker, wherein the circuit breaker forms or has the mating connector.

The plug is designed in particular for receiving a plug insert with a plurality of plug contacts and the mating plug for receiving a mating plug insert with a plurality of complementary plug contacts, wherein the plug contacts are each connected to electrical conductors.

Characterized in that a projection is provided on the lever, the connection of the plug with the mating connector during pivoting of the lever in a separation position by a power transmission from the projection on the mating connector is separable. An advantage of the solution according to the invention is that overcoming large insertion or extraction forces the projection transmits a lever force on the mating connector, which advantageously allows a simplified and secure separation of the connection.

The projection is in particular so shaped and arranged that the plug and the mating connector are removed from each other by one stretch from its connected position, that further pulling by hand without risk of injury, ie in particular without considerable effort is possible. This distance by which the plug and the mating connector are removed from each other from their connected position is preferably less than 10 millimeters and more preferably less than 6 millimeters. In general, the distance is optimally about 4 millimeters. The person skilled in the art recognizes that distances of less than 1 millimeter generally do not permit a meaningful separation of the plug from the mating plug.

According to a preferred embodiment, it is provided that the power transmission from the projection on the mating connector takes place directly on a housing of the mating connector. It is so vorteilhatterweise no additional counter bearing on the mating connector needed.

As an alternative or preferred solution to the problem, an arrangement is provided which has the plug and the complementary mating connector and is also provided for making and / or separating a connection of the plug with the mating connector, wherein on the plug a pivotable about an axis lever is arranged and according to the invention a connecting contour is provided on the lever and a pin is provided on the mating connector, wherein the connection of the plug with the mating connector can be produced upon pivoting of the lever into a connecting position by a force transmission from the connecting contour to the journal. An advantage of the arrangement is that high insertion forces, which occur in particular on a route of the insertion path immediately before reaching the final connected position, are applied simply and reliably by actuating the lever in the connection position. The connection contour is shaped so that the pin and thus the mating connector are used on the plug, or vice versa. With a latching recess arranged in the pivoting direction behind the connection contour, a latching of the lever can preferably be achieved when the connection of plug and mating plug is made when the journal can be latched into the latching recess. However, locking is not essential to the solution of the object of the invention. Rather, the arrangement preferably has a locking device which is independent of the lever and which can only be locked after the connection has been established or which can not be opened in a switched-on state of a mating connector designed as a circuit breaker, so that an exchange of a switch module, in particular Trigger module, running plug is not possible.

According to a preferred embodiment of both variants, it is provided that the lever, on the one hand, of the axle has an actuating handle for pivoting the lever about the axis, the connecting contour and / or the projection being arranged on the opposite side of the lever. In a combination of both variants, it is preferably provided that the lever has a fork, wherein the connecting contour and the projection are arranged on different arms of the fork.

According to a further preferred embodiment of both variants, it is provided that the lever between the connection position and the separation position Ober is an angular range of less than 90 ° pivotally, preferably over an angular range of less than 60 ° and more preferably over an angular range of less than 45 ° , Smaller swivel angle allow guiding the operating handle along only one side of the housing connector, which is advantageous in confined space conditions, as they are often found in switchgear, for example, industrial plants.

According to a further preferred embodiment of both variants, it is provided that an actuating handle of the lever is guided in a guide slot on an actuating side of the plug. Particularly preferably, the actuating handle can be latched in the connection position and / or in the separation position. As a result, it is clearly recognizable from the actuation side of the plug, whether the connection is made or disconnected or optionally undefined in an intermediate position. The actuation side of the plug is usually facing an operator and is opposite the plug contacts, for example.

According to a further preferred embodiment of both variants, it is provided that the actuating side of the plug is at least partially covered by a pivotable cover, wherein the cover has a lock, so that the cover is pivotable only in a position covering the operating side when the operating handle in the connection position or in the separation position, that is in particular locked. If the state of the connector is unclear, then the operating handle is in an intermediate position, so that the lock prevents covering the operating side. A preferred embodiment, which advantageously prevents incorrect operation, provides that the barrier has ramps at its edge regions, wherein the ramps are intended to displace the actuating handle into the connection position or into the separation position. This is recognizable only possible if the operating handle is already almost in the connecting position or almost in the separation position and only over a very small angular range of For example, less than 10 °, in particular less than 5 ° must be relocated.

In a designed as a switch, especially as a circuit breaker mating connector is provided that only when the cover of the operating side of the plug or the switch module, the switch is switched on. The closed cover guarantees a defined state of the connector, either completely connected or disconnected, so that when switching on the switch there is no risk that an incomplete connection is present, which can lead to damage to the electrical system. In a separate state, when the cover is closed in the release position, the lever is preferably additionally used as a transport lock.

The invention will be explained in more detail according to an embodiment with reference to drawings. The statements are exemplary and do not limit the general idea of the invention.

The FIG. 1 shows an embodiment of an inventive arrangement with a plug 11 and a complementary mating connector 12 for making and / or separating a connection of the plug 11 with the mating connector 12. An the plug 11 is a pivotable about an axis 32 lever 31 is arranged. In the illustrated embodiment, the plug 11 is a generally replaceable switch module, in particular a trigger module, which particularly preferably cooperates with a circuit breaker, wherein the circuit breaker forms the mating connector 12. The lever 31 with a longitudinal axis A is shown in an intermediate position in which the connection between the plug 11 and mating connector 12 is neither made nor separated. With the actuating handle 33 of the lever 31, this can be adjusted, wherein the adjustment is limited by a link 34 in which the actuating handle 33 is guided on an actuating side 14 of the plug 11. If the lever 31 is pivoted into a release position T, in which the axis A is approximately on the line designated T, is characterized in that on the lever 31, a projection 39 is provided, the connection of the plug 11 with the mating connector 12 by a Power transmission from the projection 39 to the mating connector 12 separately. The power transmission from the projection 39 to the mating connector 12 is preferably carried out directly on a housing 37 of the mating connector 12. The lever 31 is designed in particular as a flat component, which is aligned substantially parallel to a housing wall of the plug 11 or the mating connector 12.

On the lever 31 is still a connecting contour 38 and on the mating connector 12, a pin 36 is provided, wherein the connection of the plug 11 with the mating connector 12 can be produced upon pivoting of the lever 31 in a connection position corresponding to the designated V line. When pivoting the lever 31 into the connecting position V, the shaping of the connecting contour 38 results in force transmission from the connecting contour 38 to the journal 36, as a result of which the plug 11 and the mating connector 12 are moved toward one another, for example by a distance of 4 millimeters , whereby the range of highest insertion force is overcome. With an in the pivoting direction to the connection position V behind the connecting contour 38 arranged latching recess 17 may be an additional latching of the lever 31 in the case of manufactured connection of plug 11 and mating connector 12 are realized when the pin 36 can be latched into the recess 17.

The gate 34 serves to guide the operating handle 33 of the lever 31, the majority of which is hidden. The gate 34 has latching means 35 in both end positions, which allow a latching of the actuating handle 33 in the connecting position or in the separation position. On the plug 11, a pivotally mounted cover 20 is provided, which can at least partially cover the operating side 14 in the closed state. In the FIG. 2 the cover 20 is shown in an open position. A barrier 21 with lateral ramps 22 prevents closing of the cover 20, as long as the operating handle 33 is outside the end positions. A tab 23 is used in the closed position for locking the cover 20 with the mating connector 12, as hereinafter in connection with FIG. 3 is explained.

In the FIG. 3 is another perspective view is shown on the actuating side 14, with the cover 20 in an almost closed position, in which it is seen that the lock 21 would collide with the operating handle 33, if it is not set in one of the end positions. This is advantageously prevented. that the cover 20 can be closed in unclear state of the connection between the plug 11 and the mating connector 12. Only when the cover 20 is closed can turn the rotary knob 15 turn on the mating connector 12 in its ON position. Furthermore, a mating tab 16 is provided on the mating connector 12 for latching with the tab 23 on the cover 20, whereby the cover 20 is secured in the closed position, in particular as long as the rotary knob 15 is not adjusted to the on position. In the switch-on position, the rotary knob 15 protrudes above the cover 20 and thus also secures it in the closed position.

The FIG. 4 shows a sectional view according to FIG. 1 , wherein the region of the link 34 is visible on the plug 11 in an enlarged partial view. The Cover 20 is in the closed position. Here, the function of the ramps 22 at the web-shaped barrier 21 is clear, which are intended to relocate the operating handle 33 in one of the end positions, if it is during closure of the cover 20 only in almost one of the end positions, whereby on the one hand advantageously a certain Tolerance range is created, on the other hand, by the ramp 22, the deviation is corrected immediately. Finally, by the ramps 22 and by the lock 21 and a locking of the lever 31 in the closed position or in the separation position is realized, as long as the cover 20 remains closed.
