Description

The present invention relates to a system comprising a plug-in module for an electrical switchgear, with at least one connection contact for spring-loaded, electrical contacting of a busbar of the electrical switchgear, and a plug-in module guide for the electrical switchgear.

Plug-in modules of the generic type are widely used in the field of electrical energy supply, namely the electrical power distribution, especially in electrical switchgear. Plug-in modules may be covered by standardization, for example DIN EN 61439-2 and more. In addition, for the requirements of plug-in modules and electrical switchgear to take into account that supplementary standards in terms of electrical safety, for example DIN VDE 0100 . DIN VDE 0110 and others may be considered. Plug-in modules include electrical control devices, by means of which an energy flow and / or an energy distribution can be controlled and / or regulated.

In order to optimize an electrical switchgear with respect to creation and maintenance, different design principles are used in the prior art. A special design principle provides that an electrical control device is designed in the manner of a plug-in module for the electrical switchgear and plug-in technology can be plugged into an at least one slot for the electrical control device providing frame of the electrical switchgear. For this purpose, the plug-in module has at least one connection contact for spring-loaded, electrical contacting of a busbar of the electrical switchgear. In the inserted state, the connection contact makes contact with the busbar, so that an electrical connection to the insertion is made automatically. By plugging in, the electrical connection can therefore be automatically established. Accordingly, the electrical connection can also be automatically interrupted again when the plug-in module is removed from the slot of the electrical switchgear. Often the terminal contact protrudes for this purpose from a housing, a frame or the like of the plug-in module.

With the insertion of the plug-in module in the slot thus usually in addition to a mechanical connection to the electrical switchgear also an electrical connection of the plug-in module is made to the electrical switchgear. Other assembly or connection activities that go beyond the plugging are usually not required in this regard. Only a connection of a consumer to the plug-in module itself may still be required.

The plug-in module is not only easy to install in the electrical switchgear in this way, but it can also just as easily be removed from the electrical switchgear, for example, to adapt the electrical switchgear to other requirements or a disturbed plug-in module from the remove electrical switchgear and replace it if necessary by a functional plug-in module.

Electrical switchgear are often implemented with the aid of cabinets that accommodate at least part of the electrical switchgear. The electrical switchgear can also be arranged completely in one or more cabinets. In addition to plug-in modules electrical switchgear usually also include busbars, sometimes called busbars, can be passed through the current flow through electrical energy to the plug-in modules connected to them or from which the electrical energy can be dissipated via the busbars.

The plug-in module can be, for example, a load switch, a circuit breaker, a fuse unit, a consumer connection unit or the like or have such components. Although plug-in technology has proven its worth in the field of electrical switchgear, there are still some problems. In particular, it proves to be disadvantageous that functional checks of the plug-in module when it is plugged into the electrical switchgear can not be performed.

From the DE 10 2004 043 469 B4 is a mounting device with a switching device mounted thereon known. The mounting device and the switching device are provided with latches, so that the switching device can be held both in a contacting position and in an electrically non-contacted position. The locking lugs are formed by resilient plastic webs.

From the DE 100 03 349 B4 a mounting device for mounting an electrical switching device on a profile support rail is known, which mounting device has a snap-on the top hat rail support base on which the switching device is slidably mounted. In this way, the switching device can be moved from an electrical contacting position to an electrically separate position.

From the DE 197 38 705 A1 is designed as a slide rail trained, at which a device of the switching technology from an electrical contacting position is displaced in an electrically non-contacted position.

The devices known from the prior art enable the method of a plug-in module from an electrically contacted functional position in an electrically non-contacted test position. However, they offer no way to secure the units against unintentional manipulation or manipulation.

It is therefore the object of the invention to improve plug-in modules of the known type and to secure against unintentional displacement.

For technical solution of this problem, a system with the features of claim 1 is proposed. Further advantages and features emerge from the subclaims.

According to the invention, the plug-in module, which is arranged on the control cabinet by means of a plug-in module guide, can be moved relative to the plug-in module guide between an electrically contacted and an electrically non-contacted position. To secure the plug-in module in a respective position, this has a rod lock, which locks the plug-in module relative to the plug-in module guide.

The invention thus provides that in addition to the equipment of the plug-in module for its intended function, a test position is provided by the plug-in module, for which purpose the plug-in module is set up accordingly by means of the separating device. The plug-in module can be positioned and / or locked in different positions. The test position is a function provided in addition to the intended function of the plug-in module. The plug-in module is designed to be plugged into a frame of the electrical switchgear that provides at least one slot for the plug-in module and generally has at least one connection contact by means of which at least one bus bar of the electrical switchgear can be contacted.

Preferably, several slots can be provided. In addition, the slots can be formed by screening or have a screening, so that plug-in modules of different geometric dimensions can be arranged in a simple manner combined with each other. In particular, an arrangement density of plug-in modules can be optimized. The use of plug-in modules makes it possible to build an electrical switchgear modular and designed in a very flexible manner and to adapt to individual requirements even later. The device for separating and / or locking may in particular be a separating device.

With the invention, a disconnected position is provided, in which a consumer connected to the electrical control device in the inserted state of the plug-in module is electrically tested. The adoption of the separation position is reversible, so that after completion of tests, the operating position can be easily taken again. In the disconnected position, at least one connection contact, in particular all connection contacts of the plug-in module, is preferably separated from the busbar arrangement. This can be achieved by arranging the connection contact mechanically away from the busbar, so that there is no longer any electrical contact. For this purpose, the connection contact can be designed to be movable. The mobility is given to the busbar. In particular, the mobility can also be given with respect to the housing or the frame of the stretching module. Of course, it can also be provided that the disconnected position can be achieved by remote placement of the plug-in module of the power rail, the plug-in module, however, remains at its slot within the electrical system. In addition, it can also be provided that the rod lock introduces an electrically insulating element in the contact area in order to cancel the electrical contact. The element may be, for example, a plastic sheet or foil. It may also be a plate made of a ceramic material, an insulating composite material or the like. The element is movably mounted so that it can be moved by means of a drive of the means for separating and / or locking in the desired position. Of course, the above measures are reversible, so that in the same simple manner the intended operation can be resumed after completion of the test. For this purpose, the electrical contact between the terminal contact and the busbar is restored.

The plug-in module has at least one connection contact, with which it is in proper operation in electrical connection with the electrical switchgear. Of course, the plug-in module can have more than one connection contact. The disconnected position may relate to one or more or all terminal contacts. Preferably, however, the plug-in module is electrically released in the disconnected position, that is, the electrical connection to the electrical switchgear is interrupted. As long as such an electrical connection exists, the functional test can often, among other things, for safety reasons, for reasons practicability or other reasons. Due to the electrical connection to the electrical switchgear no selected circuits can be tested. For this purpose, it would be necessary to at least partially cancel the electrical connection to the electrical switchgear. In the case of plug-in modules of the prior art, however, this is generally only possible by completely removing the slot.

This shows an advantage of the invention that namely the plug-in module has a rod lock, by means of which in a disconnected position, the electrical control device can be electrically separated from the electrical switchgear. By means of the rod lock a test position can be provided. In this case, the invention allows the plug-in module to remain essentially in its position in the electrical switchgear, namely the slot occupied by it. If necessary, the rod lock can be designed to separate only the connection contacts of the plug-in module required for the functional test from the electrical switchgear, so that the functional test can be carried out as intended.

This is advantageous, for example, if the plug-in module is designed as a load switch, which has two connection contacts, which each contact a bus bar of the electrical switchgear in the inserted state of the circuit breaker. In order to check the switching function, it may be appropriate that only one of the two terminals is disconnected.

In addition, the electrical control device can have connections, in particular an auxiliary connection or a plurality of auxiliary connections, to which auxiliary devices can be connected, for example in order to be able to supply test voltages, test signals or the like, or also to be able to electrically tap corresponding measurement signals. It can be provided that such a connection is enabled or released only in the disconnected position of the rod lock. For this purpose, suitable locking means may be provided which can be actuated by the rod lock according to its condition. The test may involve or comprise the plug-in module and / or one or more consumers connected to the electrical control device.

The slot for the plug-in module, which may be provided by the frame of the electrical switchgear, has a guide, so that mounting of the plug-in module in the region of the slot is facilitated. The guide can also serve to align the plug-in module relative to the slot in the intended manner, so that a simple reliable and correct plugging the plug-in module can be achieved at the slot. The frame itself may be formed by a frame, a housing, guide rails, combinations thereof or the like. The frame may be formed integrally with the guide. Likewise, the leadership can also form the frame. The plug-in module can accordingly have lubricant. The lubricants may be sliding blocks or the like.

The bar lock may comprise actuating means which allow the separating position to be taken or left again. The actuating means may be mechanical in nature and include, for example, a manual or an automatic drive. The drive may include, for example, a knob, a lever, a handle or the like. The lock ensures that the plug-in module can only be moved by authorized personnel by means of the device for separating and / or locking in the disconnected position. Likewise, this can be achieved by the fact that the disconnected position is left only by authorized personnel again to allow the intended operation of the plug-in module again. Especially this state change can be important for the question of electrical safety, so that with the lock additional security can be achieved.

According to a development, a switching element may be provided. The switching element may be formed as an electrical or mechanical switch. The switching element can act on the connection contact and move it. Thereby, the electrical contact between the terminal contact and the busbar can be made or separated. It may be formed by a mechanical switch, an electronic switch, for example a lifting magnet or the like. The switching element is preferably controllable, for example manually or electromechanically by means of a drive or by a control signal, by means of which a drive for the switching element can be actuated. The control signal can be provided by the means for separating and / or locking, if it is to be moved into the disconnected position or to be moved again out of the disconnected position. The switching element is preferably part of the plug-in module. It can be arranged in a housing of the plug-in module. Preferably, the switching element is part of the device for separating and / or locking and can be integrated into the device for separating and / or locking. The switching element may further provide a bias voltage for the terminal contact, in particular for the operating state of the plug-in module.

With the rod lock used according to the invention, on the one hand, the previously mentioned safety with respect to the assumption of the disconnected position or the leaving of the disconnected position can be achieved. The same can of course be provided for the one operating position of the plug-in module, in which the plug-in module is released for normal operation.

With the rod lock can be achieved to set the plug-in module at the slot in predetermined positions, so that in one position the intended operation (operating position) and in another position, the electrical separation (disconnected position) is possible. In addition, a third position may be provided for a test position. In addition, the removal of the electronic control device from the slot of the electrical system (removal position) may be possible in a further position. For this purpose, the rod lock may comprise at least one movable rod, which may preferably protrude from the electrical control device or a housing of the electrical control device and is actuated in the longitudinal direction. With the rod, the different positions or positions of the plug-in module can be specified and / or fixed.

The bar lock can be actuated by means of a key. This can be achieved that only authorized personnel operate the rod lock and can move the plug-in module in the desired positions. Preferably, the rod lock is rotatably actuated by means of the key. In addition, it can be provided that the rod of the rod lock is manually operable, wherein the manual operation is released or locked by operating the key.

Advantageously, the rod lock is secured against unauthorized manipulation from the outside. A manipulation of the rod lock is often done by the rods are pressed or pulled from the outside to a desired position. In order to prevent such manipulation of the rods of the rod lock, the invention provides in the rod lock a spring-loaded detent, which locks the rod lock with the key removed. The catch protrudes into the bar lock so that the bars can no longer be moved. Only inserted into the rod lock key pushes the catch back out of this, so that this is released and the rod lock can now be moved by means of the key.

A further embodiment of the invention provides that the plug-in module has a locking element. The locking element makes it possible to lock the rod lock in a state, in particular in the state of the disconnected position or to fix this state. The locking element can be actuated for example by the rod lock. Preferably, the locking element may be formed by a rod of the rod lock. In addition, the locking element can of course also be formed by a separate element, which in particular allows the locking of the device for separating and / or locking in the disconnected position. It can thereby be achieved that the disconnected position is secured and can not be accidentally changed to the operating position or the removal position. For this purpose, the locking element can interact with the frame in the area of the slot, for example, in that the locking element can engage in a recess of the frame, in particular the guide. The locking element can also serve to prevent actuation of the plug-in module or to release. It can thus be provided that the locking element releases or blocks the actuation of the lock, in particular of the bar lock. Of course, locking may also be provided in the operating position. For example, it can be provided that the locking element allows the taking of different states of the plug-in module only in the deactivated state of the plug-in module. It can thus be provided that the locking element only allows the operation of the lock, in particular of the rod lock, when the plug-in module is deactivated. This can be achieved that the plug-in module can only be moved when the plug-in module is disabled. The locking element may be formed by a lever, a plate or the like. The locking element is for example displaceable and / or rotatably mounted.

As an alternative to the use of an aforementioned locking element, a forced release element can be provided which can be actuated as a function of the locking state of the rod lock. By actuating the forced release element, the connection contact of the plug-in module is automatically disconnected from the electrical contact of the busbar. This forced release thus ensures that the plug-in module is deactivated when it is moved to another position. Thus, the separation position is always secured and it can not be accidentally changed to the operating position or the removal position. When using a rod lock for determining a specific position of the plug-in module, for example, the position of the rod of the rod lock is transmitted by means of a lever on the positive triggering element of the plug-in module switch. As soon as the Rods are out of the bar lock procedure, the forced release is released by means of the lever. The switch of the plug-in module can then be activated. If, however, the rods are moved into the rod lock with the switch on, the forced release element is actuated by means of the lever and thus the switch is deactivated before the plug-in module can be moved to another position. This configuration thus always ensures that the switch has been deactivated before a movement of the plug-in module.

By the rod lock providing a test position for the plug-in module can be achieved by a plug-in module of the invention is used. Of course, it can also be provided that the provision of the test position by the electrical switchgear itself takes place outside the plug-in module. Likewise it can be provided that the provision of the test position is realized by the plug-in module in connection with the electrical switchgear.

The plug-in module is designed to be plugged into the at least one slot and has at least one connection contact by means of which at least one bus bar of the electrical switchgear can be contacted. It has the rod lock, which provides a disconnected position for the plug-in module, in which the plug-in module and / or a consumer connected to the plug-in module are electrically testable in the inserted state of the plug-in module. With the insertion of the plug-in module at the slot is also realized in addition to a mechanical connection at the same time also an electrical connection of the plug-in module to the electrical switchgear. For this purpose, the plug-in module can have at least one spring-loaded connection contact, by means of which at least one busbar of the busbar arrangement can be contacted.

In particular, the plug-in module can be completely electrically separated from the electrical switchgear by means of the rod lock. In the test position, which can be provided by means of the rod lock, the plug-in module and / or a consumer connected to the plug-in module can be electrically tested in the inserted state of the plug-in module. For this purpose, the device for separating and / or locking provides a disconnected position for the plug-in module.

The invention thus makes it possible to carry out a testing of the plug-in module and / or the consumer, without a complete disassembly of the plug-in module would be required. Rather, the invention makes it possible to leave the plug-in module arranged, preferably plugged in to leave the slot and perform the test after taking the disconnected position of the device for separating and / or locking. This simplifies inspection and maintenance operations, especially for consumers connected to the cartridge. Of course, this can also be achieved that the plug-in module itself can be tested. After completion of the test, the intended operation can be resumed immediately without the need for extensive assembly work. This is achieved by the reversibility of the separation. Thus, the invention makes it possible to provide a simple testability within an electrical switchgear. Connected consumers may be, for example, electrical machines, heaters, electro-galvanic devices, lighting systems and / or the like. Of course, an electrical load can also be an electrical generator that provides power to the distribution system via the switchgear. For the purpose of the test, the consumer can remain connected to the plug-in module.

The plug-in module has a rod lock, whose at least one rod cooperates with a recess, in particular a link, of the frame. Of course, if the frame has a guide, the rod may also cooperate with a recess in the guide. This makes it possible to allow different positions of the plug-in module in the slot for the plug-in module in a mechanical manner, for example, an operating position in which the plug-in module provides its intended operation in the electrical switchgear, a disconnected position of the operating position, for example by mechanical displacement the plug-in module along the guide of the frame can be achieved and in which the terminal contact of the busbar is electrically isolated, and optionally also a removal position, which allows removal of the plug-in module from the electrical switchgear by removal from the slot. Preferably, the rod of the rod lock engages in the recess of the frame, in particular in the disconnected position and optionally also in the operating position. The recess may be formed adapted to the cross-sectional dimensions of the rod. As a result, the respective position of the plug-in module can be determined at the slot by means of the rod. Of course, the recess may also be formed by a backdrop or a plurality of openings, which allows different locking options for fixing the plug-in module in the region of the slot. Of course, a kinematic reversal can be provided, for example by the rod lock on the frame or on the guide and the recess are provided on the plug-in module. Advantageously, the rod lock on a detent, which a Manipulation on the bars of the bar lock prevented. A spring-loaded catch engages the bar lock as soon as the key is removed from the bar lock.

This catch locks the bar lock with the key removed. As a result, the rods can no longer be moved. Only when the key is reinserted into the bar lock and thus pushes the catch out of the bar lock, the rods of the bar lock can be moved again.

It is advantageous if the plug-in module has a switching element, by means of which in a disconnected position, at least one connection contact of the plug-in module is electrically separated from the busbar of the busbar arrangement. This can be achieved, for example, in a mechanical manner in that the connection contact is movable, in particular resilient, and can be actuated by means of an actuating element in order to be able to reach the separate position from the busbar. The actuator may be formed by a handle for manual operation but also by a drive for automatic operation, for example in the form of a solenoid or the like. Of course, the actuator may also be configured to urge the terminal contact in the operative position against the bus bar to establish the spring-loaded electrical contact. In addition, it can be provided that with the switching element and the plug-in module can be moved in order to achieve the separation of the terminal contact of the busbar can. For this purpose, a drive for manual operation or for an operation in electrical, pneumatic, hydraulic or the like may be provided in addition.

A development provides that the electrical switchgear, in particular the plug-in module has a locking element, in particular for the rod lock. This can ensure that the rod lock can only be actuated under specifiable conditions. In particular, it can be provided that the disconnected position and / or the operating position can be approached or left again only under predefinable conditions. The locking element may be formed by a mechanical lever or the like. Preferably, the locking element is movable between an interlocking and / or an unlocking position, in particular displaceable or rotatable. The locking element can be actuated by a unit of the plug-in module, for example a switch, a circuit breaker or the like. The locking element can detect the operating state of the plug-in module and, for example, enable or disable the operation of a lock depending on the operating state.

As an alternative to the above-described locking element, the electrical switchgear can have a forced release element which can be actuated as a function of the locking state of the device for separating and / or locking. For example, when using the bar lock, the position of the bar is transmitted to the forced-release element by means of a lever. As soon as the rods are moved out of the bar lock, the forced release element releases the switch of the plug-in module. The switch can thus be turned on. If, on the other hand, when the switch is turned on, the rods are moved into the bar lock, the forced release element is actuated by means of the lever and thus the switch is deactivated so that the plug-in module can be moved to another position without danger.

The invention enables a method for testing a plug-in module and / or a consumer connected to the plug-in module, which is arranged in normal operation at a slot of a frame of an electrical switchgear and electrically contacted with at least one terminal contact a busbar of the electrical switchgear, wherein the electrical contact of the terminal contact with the busbar is reversibly separated by means for separating and / or locking.

This makes it possible to ensure that the testing at the slot of the plug-in module, in particular in the plugged state of the plug-in module in the electrical switchgear, is made possible without the need for extensive assembly work. The plug-in module can be moved by moving in the region of the slot of the frame, for example along a guide. In the disconnected position, the plug-in module can be positioned at the slot such that a terminal contact of the plug-in module does not contact a bus bar of the electrical switchgear. Thus, the test can be carried out in a simple manner promptly with little effort. The mechanical procedure of the plug-in module takes place between an operating position and a disconnected position.

In the disconnected position, a connection contact of the plug-in module is disconnected from a busbar of the electrical switchgear. As a result, operating voltage can be switched off the plug-in module, so that a test can be achieved with simple means. In particular, a high level of security can be achieved, although that Plug-in module is still positioned or arranged on the slot.

The plug-in module is deactivated for the purpose of the method. This feature proves to be particularly advantageous in connection with the separation of the connection contact from the busbar, since in the deactivated state the formation of dangerous arcs can be largely avoided. Overall, this can increase the safety with respect to the process implementation of the invention. The deactivation can be achieved by a switching element or the like.

Deactivation is locked. This provides additional security, since accidental activation of the plug-in module can be largely prevented. The locking of the deactivated state of the plug-in module can take place by means of a locking element, for example in the form of a lever, which lever acts on the rod lock or the like. The locking element can act on a component by means of which an activation of the plug-in module can be effected in the operating state. The locking can also be achieved or supported by a lock, in particular bar lock. The rod lock can also be secured against manipulation of the rods by means of a spring-loaded catch, wherein the catch projects with the key removed into the rod lock, so that the rods can not be moved. Only inserted into the rod lock key pushes the catch back out of this, so that the rod lock can be moved by means of the key again.

In the disconnected position, an auxiliary connection can be connected. With the auxiliary connection, the plug-in module can be electrically connected to other devices and / or facilities. It is thus possible to apply or record control, test and / or measured variables to the plug-in module via the auxiliary connection. This not only the function of the plug-in module itself, but also the function of the consumer connected to it can be checked. Of course, the auxiliary connection can also be provided to receive measured variables and to evaluate them in external devices and / or devices.

The plug-in module can be locked in the disconnected position. This can ensure that the disconnected position is not left accidentally. An improved security can be ensured. In addition, this can be achieved that in the area of the auxiliary terminal no dangerous conditions can occur. Particularly advantageously, the locking can serve to block a contacting of the auxiliary terminal in the operating position. This can further improve safety. The locking can be realized by means of a locking element, in particular by means of the rod lock.

The plug-in module can be activated or deactivated by actuating the rod lock. The current position of the rod of the rod lock is transmitted by means of a lever on a forced release element of the plug-in module. If the rods have moved out of the rod lock, the forced release of the switch is released. The switch can thus be turned on. If the rods are moved into the bar lock when the switch is switched on, the forced release of the switch is actuated by means of the lever and thus the switch is deactivated. The plug-in module can then be moved to another position. By this configuration it is achieved that the switch is always activated when the rods are retracted into the lock to move the plug-in module in another position.

Further advantages and features will be apparent from the following description of an embodiment.

1 shows the application of the invention in an electrical cabinet 26 in open position. The control cabinet 26 contains a not further described electrical switchgear with a busbar assembly, the busbars 12 includes. In the schematic representation in 1 is a perspective view of a section of the open cabinet 26 , At the bottom of the 1 are each in pairs parallel busbars 12 seen. It can be seen that on the power rails 12 a plug-in module 42 as an electrical control device with a switch 40 is arranged. The desk 40 is in this case a circuit breaker. But it can also be a load switch, a circuit breaker or the like. The plug-in module 42 is via a plug-in module guide 44 guided and on a distribution rail system 66 plugged. The plug-in module guide 44 is part of a framework 14 , which in turn is part of the control cabinet 26 is.

By means of the plug-in technology, it is possible plug-in modules such as the plug-in module 42 even to assemble or disassemble when the busbars 12 perform their intended function of the power distribution, that is, are subjected to electrical voltage.

To when mounting or dismounting the plug-in module 42 To be able to avoid arcs, it is provided in the present case that the switch 40 only in the off state, a mounting or dismounting of the plug-in module 42 allowed. Unsigned contact lugs of the plug-in module 42 , the connection contacts of the plug-in module 42 form, spring-loaded contact in an operating position in the fully inserted state of the plug-in module 42 at the slot 10 the corresponding busbars 12 through contact openings 38 a cover 36 , by means of the busbars 12 protected in the control cabinet 26 are arranged. For this purpose, the connection contacts are in the present case designed as spring elements themselves.

2 shows the plug-in module 42 in a perspective view, in which the switch 40 is off. In this switch position is a keyhole 52 a bar lock 56 accessible or released. The bar lock 56 forms together with a still described below 62 a device for separating and / or locking 16 , The device for separating and / or locking 16 provides a disconnect position, which is present at the same time a test position, and an operating position ready in both the plug-in module 42 as well as a consumer connected to it. By means of the device for separating and / or locking 16 is the electrical contacting of the bills 12 reversibly separable with the connection contact, as will be explained in more detail below.

A sliding plate 48 serves the position of a drive 46 of the switch 40 to pick up and on a telescopic rail 50 transferred to. The telescopic rail 50 serves to adjust the position of the drive 46 of the switch 40 capture and the keyhole 52 depending on the operating position of the drive 46 to obscure or release. The plate 48 thus forms together with the telescopic rail 50 a locking element. This is the operation of the bar lock 56 only possible if the switch 40 is off. 2 shows that in the keyhole 52 a key 54 is introduced by means of which the bar lock 56 is operable. At the same time it is achieved that the drive 46 can only be operated if no key 54 in the keyhole 52 is plugged in.

In the present case it is envisaged that the keyhole 52 only in the off position of the drive 46 of the switch 40 is accessible as it is in 2 is shown. Out 2 is also apparent that in the keyhole 52 a key 54 is inserted, which is the bar lock described in detail below 56 ( 4 ).

In the present embodiment, it is further provided that the key 54 in the keyhole 52 introduced only in a preferred position or out of the keyhole 52 can be removed. This is the preferred position in which the bar lock 56 locked or unlocked. An inserted key 54 continues to hamper a method of telescopic rail 50 , so the switch 40 can not be operated. As long as the key 54 is plugged, this is how a switch-on protection guaranteed.

3 shows the plug-in module 42 with the switch 40 when switched on. How out 2 can be seen is the keyhole in this state 52 through the telescopic rail 40 covered. An operation of the bar lock 56 by means of the key 54 is therefore not possible in this position.

4 now shows in the sectional plan view of the substantially for the bar lock 56 required parts. Essentially, the bar lock points 56 two bars 58 on, by means of the bar lock 56 are displaceable in the longitudinal direction. The bars 58 are mounted longitudinally displaceable. The displacement takes place by an actuation of the keyhole 52 introduced key 54 , Depending on the direction of rotation of the key 54 become the rods 58 either in the plug-in module 42 pulled in or out. End of the housing of the plug-in module 42 Outstanding are the ends of the rods 58 Multiple bends on. These multiple bends act in the mounted state with the plug module guide 44 , especially with the backdrop 62 , together and lock the plug-in module 42 in a predetermined position or position. In addition, it is achieved that the key 54 can not be further rotated by further rotation in a further non-locking key position after reaching a locking key position. With regard to the positions or positions will be further elaborated below.

5 shows in perspective a side view of the plug-in module 42 according to 1 , and plugged in at the slot 10 of the control cabinet 26 together with the plug-in module guide 44 , Is shown in 5 the operating position of the plug-in module 42 ,

It can be seen that the plug module guide 44 an unspecified opening with a stop 60 as well as a backdrop 62 for the bars 58 having. The bars 58 protrude in the inserted state of the plug-in module 42 the non-designated recess formed as an opening, the stop 60 as well as the scenery 62 provides. This also results in the possibilities of movement of the rods 58 That is a setting of the plug-in module 42 or a release of the plug-in module 42 in the control cabinet 26 allow or block.

How out 5 can be seen, the plug-in module 42 in the slot 10 be arranged in two spatially separate preferred positions, namely in an operating position, as in 5 is shown, as well as in a position at which the rod 58 at the stop 68 is applied. In this disconnected position is the plug-in module 42 opposite the busbars 12 arranged away, so that not shown in detail terminal contacts of the plug-in module 42 from the busbars 12 are electrically isolated.

Accordingly, the plug module guide 44 over the backdrop-shaped opening, by means of the scenery 62 pretends these two privileged positions. The operating position and the disconnected position are by interaction of the rods 58 with the backdrop 62 given.

In the operating position is the plug-in module 42 inserted in such a way that its terminals in the intended manner the corresponding busbars 12 Contact spring-loaded. In this position is the plug-in module 42 ready for its intended use.

Furthermore, it is off 5 you can see that the rod 58 has assumed its maximum outward position in the operating position. In this position is the plug-in module 42 through the pole 58 in cooperation with the scenery 62 locked. This position is also in the same time 2 and 3 shown. In this position is also a removal of the key 54 from the keyhole 52 of the bar lock 56 possible so that the telescopic rail together with the plate 48 is freely movable. That's why the drive can 46 of the switch 40 with the key removed 54 be operated arbitrarily in the desired manner.

To the plug-in module 42 To move into the disconnected position, is first the drive 46 of the switch 40 to switch to the "off" position. At the same time this operation on the plate 48 and the telescopic rail 50 the keyhole 52 released, so that, as in 2 represented, the key 54 can be introduced. With the key 54 becomes the bar lock 56 pressed, so the rods 58 in the plug-in module 42 be in process. In this state is an area 18 the pole 58 in a backdrop area 20 , which is a procedure of the plug-in module 42 allowed from the operating position to the disconnected position. The plug-in module 42 can thus by manual partial extraction in the slot 10 be moved into the disconnected position. The process is done until the rods 58 at the stop 68 attacks. So that in the disconnected position a test is possible by means of the key 54 the bar lock 56 press again in the opposite direction so that the rods 58 again from the plug-in module 42 will be out. This will be the plug-in module 42 set or locked in the release position, the rods 58 now at the stop 68 issue. In this position can be the key 54 back out of the keyhole 52 be removed, so that in this position the drive 46 of the switch 40 is operable. This is necessary for the desired tests to be carried out. In the disconnected position, the connection contacts, not shown, of the plug-in module 42 from the corresponding busbars 12 disconnected so that there is no electrical connection. Via the auxiliary connection, not shown, external devices and devices can be connected in order to carry out the test in the desired manner.

To the plug-in module 42 from the slot 10 It is necessary to remove the bar lock completely 56 in the disconnected position again by means of the key 54 to press. In the disconnected position can namely the rod 58 with its multiple bends due to the backdrop of the backdrop 62 completely into the plug-in module 42 be in process. Prevent in the operating position this the multiple bends, with the backdrop 62 interact so that the rods 58 not completely in the plug-in module 42 can be recovered ( 5 ). This will get the rods 58 out of engagement with the opening of the plug-in module guide 44 so that the plug-in module 42 manually from the slot 10 can be pulled out. In the present case it is provided that a removal of the plug-in module 42 from the slot 10 only possible from the disconnected position and not from the operating position. This is by shaping the ends of the rods 58 and the shape of the opening ( 5 ). For removing the plug-in module 42 from the slot 10 is the plug-in module 42 thus first to transfer from the operating position to the release position.

Should only the plug-in module 42 From the disconnected position are moved back to the operating position, so is the switch 40 over the drive 46 to switch to the "off" position. In this position is the keyhole 52 accessible again, leaving the key 54 plugged in and the bar lock 56 can be operated. At the same time the bars become 58 again so far in the plug-in module 42 proceed that area 18 back in the scenery area 20 can protrude. In this position, the plug-in module 42 be pressed back into the operating position. Has the plug-in module 42 the operating position is reached by re-operating the rod lock 56 in the opposite direction the rods 58 moved to the fully extended state, so that the operating position is locked. In this position can be the key 54 removed again and thus the plug-in module 42 be released for its intended operation. In this position, contact the connection contacts of the plug-in module 42 spring-loaded again the busbar 12 , As a result, the reversibility is established. The spring load can be provided by a separate spring element, but also by the terminal contacts themselves. But it can also by the means for separating and / or locking 16 to be provided.

For mounting an unplugged plug-in module 42 at the slot 10 is first by means of the key 54 the bar lock 56 to operate such that the rods 58 completely into the plug-in module 42 are in-process. The desk 40 is of course switched off. In this position, the plug-in module 42 into the plug-in module guides 44 be introduced until the separation position is reached. In this position, by operating the rod lock 56 the bars 58 from the plug-in module 42 be moved out, so they into the the scenery 62 forming opening of the plug-in module guide 44 intervention. In the first intermediate position of the bar lock 56 the rods protrude 58 with her area 18 in the scenery area 20 so that the plug-in module 42 between the separation position and the operating position is movable. Will the bar lock 56 in the disconnected position further actuated, the disconnected position is locked as described above.

The plug-in module 42 can be moved by further impressions but also directly, that is, without prior Verrieglung in the disconnected position, in the operating position and then a further actuation of the rod lock 46 the complete moving out of the bars 58 effect in the operating position. This is the plug-in module 42 set in the operating position. The key 54 can be removed both in the locked disconnected position and in the locked operating position, so that the switch 40 of the plug-in module 42 is released for actuation.

A direct plug in the operating position is through the scenery 62 and the multiple bends of the ends of the rods 58 prevented, so in the present case for the insertion of the plug-in module 42 at the slot 10 always first take the disconnected position.

The locking by means of the telescopic rail 50 and the plate 48 allows the plug-in module 42 in the disabled state can be locked by the key 54 in the keyhole 52 is inserted.

6 shows an enlarged view of the pole lock 56 and a corresponding key 54 , The bar lock 56 has two bars 58 , To secure the bar lock 56 against a manipulative moving the rods 58 is a catch 69 arranged, which is a shifting of the rods 58 prevented and only by means of the key 54 from the bar lock 56 can be removed.

7 shows a plug-in module 42 in a sectional view. The plug-in module 42 has a bar lock 56 with two bars 58 and a forced release element 70 on which a lever 71 with the rods 58 connected is. This variant is an alternative to that in the 1 to 3 illustrated locking element 48 . 50 This is the switch 40 of the plug-in module 42 automatically based on the current position of the pole 58 on or off. For this purpose, the position of the rod 58 over the lever 71 on the forced triggering element 70 of the switch 40 transfer. Once the rods 58 from the bar lock 56 be moved out, the forced trigger element 70 of the switch 40 over the lever 71 Approved. The desk 40 can then be turned on. When switched on 40 the bars 58 in the bar lock 56 be driven in, the forced release element 70 by means of the lever 71 actuated. As a result, the switch becomes 40 disabled, leaving the plug-in module 42 can be moved to another position without danger. This automatic positive release ensures that the switch 40 Always off when the plug-in module 42 is moved to another position. The locking element 48 . 50 eliminated.
