Description

The present invention relates to an arrangement of isolating terminals with at least one coupling device according to the preamble of claim 1. The invention also relates to an isolating terminal with a coupling device and to an isolating terminal with a switching status display.

Such disconnect terminals are used in different applications.

DE 44 44 551 A1 describes a current transformer isolating terminal with a contact piece in the form of an angle-adjustable contact disc, which uses a contact trailing distance to ensure that the secondary side of a connected current transformer can never be open when the current passage through the terminal is disconnected or closed. The contact disk can be adjusted in angle about an axis of rotation by means of a pivot lever. The actuation of the current transformer disconnect terminal, i.e. the manual pivoting of the pivot lever from one switching position to the other in the case of several immediately adjacent disconnect terminals en bloc, can be done by inserting a coupling pin into the handle knobs of the pivot lever of the immediately adjacent disconnect terminals.

DE 44 44 556 A1 refers to switchable terminal blocks with a switch lever handle made of insulating material. The handle is provided with two visible surfaces, of which, in each of the two switching positions of the shift lever, the one visible surface alternately faces the operator's line of sight and the other seat faces away from the operator's line of sight in the same switch position. The grips of directly adjacent terminal blocks can be coupled by means of a transparent cap that overlaps two or more grips.

DE 10 2008 014 176 B4 describes a terminal block and also a longitudinal disconnector with a cutting blade for pivoting arrangement in a terminal housing of the terminal block, with a terminal housing, wherein a busbar consisting of two sections and two conductor connection elements for connecting one conductor each to a section of the busbar are arranged in the terminal housing the two sections are connected to one another in a first position of the cutting knife and are separated from one another in a second position of the cutting knife. The cutting knife is partially surrounded by an insulating housing. An actuation of the line disconnector can not only be done with the help of a screwdriver, which is inserted into an actuating shaft of the insulating housing for this purpose, but also take place with the aid of a switch connection which has two legs and a handle section connecting the legs. In this way, two line disconnectors of two series terminals arranged next to one another can be actuated at the same time, for which purpose one leg is inserted into the actuation shaft of a line disconnector.

The known isolating terminals have proven themselves. It is considered to be disadvantageous that a separate adjustment of the shift levers connected to connecting elements is only possible independently of one another when the connecting element is removed again.

However, it is desirable to develop these isolating terminals further, allowing a simple, fast and reversible switch connection and maintaining or improving a compact design and a small number of components, and at the same time also enabling the switch position to be recognized.

The object of the invention is to solve this problem. The invention achieves these objects by the subject matter of claim 1 and by the subject matter of claims 20 and 24.

An arrangement according to the invention comprises at least two isolating terminals and at least one coupling device, the at least two isolating terminals each having at least one switching lever, each switching lever being adjustable from a first switching position to at least one second switching position and back independently of the other switching lever, the switching lever being adjustable by means of the at least one coupling device can be connected. The at least one coupling device connects the shift levers to one another when the at least one coupling device is switched into at least one first coupling position, and the at least one coupling device separates the shift levers from one another when the at least one coupling device is switched into at least one second coupling position.

This results in an advantageously simple and quick connection of the switching levers of the disconnecting terminals as well as an equally simple and quick release of the connection of the switching levers by means of the coupling device in two different coupling positions. In addition, other coupling configurations can be made possible by further coupling positions.

Another advantage is that all disconnect terminals can be used with the same structure.

In addition, it is possible that not just two, but switching levers of several isolating terminals can be connected in an advantageously simple manner.

An isolating terminal according to the invention has the coupling device described above.

Another isolating terminal according to the invention, in particular for the arrangement specified above, comprises at least one switching lever, the switching lever being adjustable from a first switching position to at least a second switching position and back independently of the other switching lever. The isolating terminal has a switching status display with a movable display section and a stationary display section, the switching status display visibly indicating the respective switching position or at least one further switching position of the shift lever, with these two display sections being combined in the first switching position in such a way that "closed" symbols are unambiguously is visibly recognizable, and this symbolism is separated in the second switch position, from which a separation is clearly recognizable.

This enables an advantageously simple and unambiguous display of switching states.

It should be pointed out here that such a switching status display can also be used for other types of terminals that do not have any coupling elements. Such a terminal with switching status display can also be the subject of a separate application.

In one embodiment, the at least one coupling device has at least one coupling element which can be switched from the at least one first coupling position into the at least one second coupling position or into at least one further coupling position and back. It is advantageous that the coupling element can be switched, since this enables clear switching states.

It is also advantageous that the at least one coupling element is held captive on the switching lever of one of the at least two isolating terminals.

One embodiment provides that the at least one coupling element is linear in the radial direction with respect to a pivot axis of the shift lever from the at least a first coupling position can be switched into the at least one second coupling position or into the at least one further coupling position and back. Switching is thus achieved with an advantageously simple linear pulling and pushing process.

Another arrangement provides that the at least one coupling element linearly in the radial direction with respect to a pivot axis of the shift lever from the at least one first coupling position into the at least one second coupling position or into the at least one further coupling position and back vertically or at an angle in relation can be switched to the direction of movement of a shift lever.

In one embodiment, the at least one coupling element comprises at least one switching pin, at least one driver and at least one handle, the at least one switching pin being longer than the at least one driver. This is advantageous because the longer switch pin can thus remain in its arrangement in both coupling positions, even if the driver is no longer in engagement.

For this purpose, a further embodiment provides that the at least one coupling element with the at least one switching pin is received in a receptacle of the one switching lever of the at least one isolating terminal so that it can be displaced and in the at least one first coupling position and in the at least one second coupling position or in the at least one further Coupling position is fixed in each case by a locking mechanism. In this way, the coupling positions can advantageously be determined in a simple manner.

It is also advantageous that the at least one switching pin of the at least one coupling element comprises a lug and at least one detent spring with at least one detent as a detent mechanism, since a simple and compact detent mechanism is formed in this way.

In a further embodiment, the at least one driver in the at least one first coupling position engages at least one receptacle of the adjacent or at least one closest or at least one shift lever located a multiple of a grid away, and the at least one driver is in the at least one second coupling position or in the at least one further coupling position out of engagement with the at least one receptacle of the adjacent or at least one closest or at least one shift lever arranged at a multiple of a grid away. One advantage here is the simple and compact structure.

An alternative embodiment provides that the at least one coupling element can be switched rotationally about an axis from the at least one first coupling position into the at least one second coupling position or into the at least one further coupling position and back, the axis being tangential to an imaginary circle with a center point , through which a pivot axis of the shift lever runs, or the axis is coaxial or at an angle with respect to the direction of movement of a shift lever. This is advantageously simple and space-saving.

In a further embodiment, the at least one coupling element is a kind of elongated hood and comprises a pivot section, a shaft section with the axis and at least one coupling section, the shaft section of the at least one coupling element being received and pivotable about the axis in a receptacle of a radially protruding actuation section of the shift lever is held captive by a suitable means, for example an undercut. It is also advantageous here that the coupling device can be retrofitted in a simple manner.

It is advantageous that the at least one coupling element is pivoted in the at least one first coupling position via the radially protruding actuation section of at least one of the adjacent or at least one closest or at least one shift lever located a multiple of a grid away and is positively coupled to at least this one, wherein the At least one coupling section of the at least one coupling element surrounds the radially protruding actuation section of at least one of the adjacent or at least one closest or at least one shift lever located a multiple of a grid away like a hood, since in this way the switching state of the shift lever is particularly clearly visible.

In a further embodiment, the at least one coupling element is held in the at least one first coupling position in a first latching position, with at least one projection on the inner sides of side walls of the at least one coupling section of the at least one coupling element in engagement with ends of the receptacle of the actuating section of at least the adjacent or at least one shift lever closest to it or at least one shift lever located a multiple of a grid away, and the at least one coupling element is held in the at least one second coupling position in a second latching position, at least one latching device with a protruding section and a corresponding molded section being provided .. The protruding section is in one version on the attached movable coupling element and the molded portion is located on a stationary part, for example on the actuating portion. Of course, it is also possible for the protruding section to be arranged on the stationary part and for the molded-in section to be located on the movable coupling element. It is also conceivable that a combination of two or more such latching devices is provided. The protruding section of the one latching device can be attached to the movable coupling element, and the protruding section of the other latching device is stationary. An advantage here is a simple structure and the usability of identically designed isolating terminals.

In another alternative embodiment, the at least one pivotable coupling element is arranged in a receptacle in at least one actuating section of the at least one shift lever so that it can pivot about at least one axis and cannot be lost, the respective receptacle having at least one slot through which the at least one coupling element can be mounted. One advantage here is the space-saving and particularly compact design.

Another embodiment provides that the at least one coupling element in each case comprises a cylindrical body with an associated pivot axis and at least one arm attached to the body with at least one hook section. A narrow and space-saving structure is thus possible.

In yet another embodiment, the at least one hook section extends in the at least one first coupling position through the at least one slot and is in at least one further receptacle of the actuating section of at least one of the adjacent or at least one closest or at least one shift lever arranged a multiple of a grid away Engagement, wherein the at least one hook portion remains in the at least one second coupling position in the respective corresponding receptacle. This is advantageous because a particularly compact structure can be made possible.

For an advantageous definition of the coupling positions, it is provided that the at least one coupling element in the at least one first coupling position and in the at least one second coupling position or in the at least one further coupling position each by means of at least one nose, which in the respective coupling position in engagement with a respective stationary recess is locked.

It is also advantageous that the at least one coupling element can be switched by means of a tool, since no additional functional parts have to be introduced from the outside of the switch lever and enlarge the switch lever.

In yet another embodiment, the at least one actuation section of the at least one shift lever with the corresponding receptacles with the at least one coupling element and the corresponding receptacles can be designed as at least one box-shaped area or receptacle section as a separate part, which is suitably attached to the at least a shift lever is attached. This enables advantageous retrofitting and assembly. The actuation section can thus be manufactured and assembled separately.

It is also advantageous that the isolating terminal has a switching status display with a movable display section and a stationary display section, which visibly displays the respective switching position or at least one further switching position of the switching lever, with these two display sections being combined in the at least one first switching position so that one "Closed" symbols are clearly visible, and in the at least one second switch position these symbols are separated, from which a separation can be clearly recognized.

A further embodiment provides that at least the first switch position is indicated by a cover and / or a display section and at least the second switch position is displayed by a cover and / or a display section. This results in a compact structure.

In yet another embodiment, the switching status display advantageously supports recognizability by means of coloring, symbols and / and geometry.

In one embodiment of the isolating terminal, at least the first switch position is displayed by a cover and / or a display section and at least the second switch position is displayed by a cover and / or a display section. Such a structure is advantageously compact.

In a further embodiment of the isolating terminal, the switching status display can support recognizability by means of coloring, symbols and / and geometry. This is advantageous because it can also be seen from a greater distance. Further advantageous refinements can be found in the remaining subclaims.

The terms “top”, “bottom”, “left”, “right” relate to the respective arrangement of the components in the figures.

Fig. 1 shows a schematic perspective view of a conventional isolating terminal 1 in an arrangement 10, which here has two isolating terminals 1, 1 '(there can of course also be more than two isolating terminals 1, 1').

To distinguish between the two isolating terminals 1, 1 ', the reference symbols of the rear isolating terminal 1' arranged in the figures, including the reference symbols of their individual parts / sections, are each identified with an apostrophe. In the description, different features of the front and rear isolating terminal 1, 1 'are shown separately.

Such isolating terminals 1, 1 'are also referred to as sequential isolating terminals 1, 1', measuring isolating terminals or series isolating terminals.

The isolating terminal 1, 1 'comprises a housing 2, 2' with a first connection section 3, 3 ', a second connection section 4, 4' and a separating section 5, 5 'arranged centrally between them.

In the first connection section 3, 3 'there is arranged a first clamping section (not described in more detail) for connecting an electrically conductive line (not shown). The first clamping section is connected to a first conductor rail 3a, which extends into the separating section 5 with a connecting section (not designated).

In a similar way, a second terminal section (not described in more detail) for connecting a further electrically conductive line (not shown) is arranged in the second connection section 4, 4 'in a mirror image of the first connection section 3, 3'. The second clamping section is connected to a second conductor rail 4a, which extends with a connecting section (not designated) into the separating section 5, 5 '.

The connecting sections of the conductor rails 3a and 4a are in operative connection with a switching device (not shown) in the separating section 5, 5 '. The switching device has a switching lever 6, 6 'which can be adjusted from a first switching position I into a second switching position II and back. The switching lever 6, 6 'pivots in a switching movement SB about a pivot axis 5a.

The pivot axis 5a here runs perpendicular to the side surfaces (not designated) of the housing 2, 2 'of the isolating terminal 1, 1'.

In the first switch position I, which is also referred to as the connection position, the switching device connects the two connection sections and thus the first conductor rail 3a and the second conductor rail 4a in an electrically conductive manner, so that the first clamping section is electrically conductively connected to the second clamping section. The upper region of the shift lever 6 with an actuating section 7 rests against a stop section 9 of the housing 2, as in FIG Fig. 1 for the front isolating terminal 1 is shown.

In the second switching position II, which is also called the disconnected position, the two connecting sections are separated and insulated from one another, ie the electrically conductive connection of the two connecting sections and thus the conductor rails 3a and 4a is canceled or separated, with the conductor rail 3'a continuing here is electrically connected to the shift lever 6 '.

In this second switching position II, the actuating section 7 'of the switching lever 6' rests on a further stop section 9'a of the housing 2, as in FIG Fig. 1 for the rear isolating terminal 1 'is shown. Furthermore, in switching position II, a cross-bridge (not shown) is contacted in such a way that, in the case of switching position II, all adjacent isolating terminals are conductively connected / short-circuited to one another via this cross-bridge. The cross bridge is provided with similar contacts as the conductor rails 3a, 4a towards the switch lever.

In the example shown in Fig. 1 a receptacle 8, 8 'is formed in the actuating section 7, 7' from above in the radial direction in relation to the pivot axis 5a.

The switching lever 6, 6 'is here operated manually and / or with a suitable tool, e.g. a screwdriver in engagement with the receptacle 8, 8'.

The actuating section 7, 7 'of the shift lever 6, 6' each has two opposite side sections. There are first of all end face sections 7a, 7'a, which point to the connection sections 4, 4 'of switching position I. These face sections 7b, 7'b lie opposite, which point to the connection sections 3, 3 'of the switching position II. Side sections 7c, 7'c, the surfaces of which run perpendicular to the pivot axis 5a, lie at right angles thereto. And respective side sections 7d, 7'd lie opposite these.

In Fig. 2 is a schematic perspective view of a first embodiment of a disconnect terminal 1, 1 'according to the invention with a coupling device 100 according to the invention. The arrangement 10 has two adjacent isolating terminals 1, 1 '.

The coupling device 100 is used to couple at least two adjacent shift levers 6, 6 'of two adjacent isolating terminals 1, 1'.

The term “coupling” is to be understood as meaning that at least two adjacent shift levers 6, 6 'are locked together or connected in such a way that they can be moved together from shift position I into shift position II and back. When the "coupling" is canceled, the shift levers 6, 6 'are separated from one another again and can be actuated independently of one another.

At the in Fig. 1 The usual disconnect terminal 1, 1 'shown, a type of bracket plug with two plug pins is inserted into the receptacles 8, 8' of the switch levers 6, 6 'of the disconnect terminals 1, 1'. The two switching levers 6, 6 'can be connected and adjusted together by means of this bracket connector. A separate adjustment of the switch levers 6, 6 'independently of one another is only possible if the bracket plug is removed again.

The coupling device 100 of the exemplary embodiment according to FIG Fig. 2 comprises, in contrast, a switchable or adjustable coupling element 11 which, as shown here, couples two shift levers 6, 6 'with one another, but, as is easy to imagine, can also be designed for more than two shift levers 6, 6'.

The term “switchable” is to be understood as an adjustment of the respective coupling element 11, 18, 22 of the coupling device 100 from a first position to a second position and back. This adjustment can take place rotationally and / or linearly.

It is also conceivable, but not further elaborated, that there may be further switching positions / mechanisms which, for example, can bring about a coupling of a central isolating terminal to isolating terminals arranged next to it on the left or right. This is not shown, but it is easy to imagine.

In the actuating sections 7, 7 'of the shift levers 6, 6', two receptacles 8, 8a and 8 ', 8'a lying next to one another are formed in the circumferential direction in relation to the pivot axis 5a. The receptacles 8a, 8'a serve to receive the coupling element 11 and are arranged between the receptacles 8, 8 'and end-face sections 7a, 7'a of the actuating section 7, 7'.

In the switching position I, the end face sections 7a, 7'a are each in contact with a stop 9, 9 'of the housing 2, 2'. In the switching position II, further end face sections 7b, 7'b of the actuating sections 7, 7 'of the switching levers 6, 6' are each in contact with the further stop 9a, 9'a of the housing 2, 2 '.

The coupling element 11 is inserted into one of the shift levers 6, 6 'and held captive in this locking behind. Furthermore, the coupling element 11 is slidably guided in this shift lever 6, 6 'and can be moved from a first coupling position A into a second coupling position B (see FIG Fig. 4 , 6, 7 ) can be switched. This is explained in detail below.

Fig. 3-9 show schematic perspective partial views of the coupling device 100 according to FIG Fig. 2 in different coupling positions A, B and switch positions I, II.

In Fig. 3 the coupling element 11 is shown in a so-called pre-assembly position before it is inserted into the receptacles 8, 8 'of the shift levers 6, 6'. The switching levers 6, 6 'are both in switching position I on the stop sections 9, 9' of the respective housing 2, 2 '.

The coupling element 11 comprises a switching pin 12, a driver 13 and a handle 14. The switching pin 12 and the driver 13 are attached to an underside 4 a of the handle 14. A length of the switching pin 12 is more than twice as great as a length of the driver 13. The switching pin 12 and the driver 13 are arranged next to one another with reference to the pivot axis 5a.

Fig. 4 shows the isolating terminals 1, 1 'with the switching levers 6, 6' and the coupling device 100 in the switching position I, the switching position II in FIG Fig. 5 is shown.

The coupling element 11 is inserted here in the receptacles 8a, 8'a of the actuating sections 7, 7 'of the shift levers 6, 6' linearly in the radial direction with respect to the pivot axis 5a that the long shift pin 12 in the receptacle 8a of the shift lever 6 the in Figures 2 to 9 front isolating terminal 1 shown is received, and the short driver 13 in the receptacle 8'a of the shift lever 6 'of the in Figures 2 to 9 shown rear disconnect terminal 1 'is received or is in engagement with this. The underside 4a of the handle 14 of the coupling element 11 rests on surfaces 7e, 7'e of the actuating sections 7, 7 '. This position of the coupling element 11 corresponds to the first coupling position A ( Fig. 4 ), in which a coupling, which is also referred to as a lock, the shift lever 6, 6 '(mechanically) is switched on.

In this way, the switching levers 6, 6 'in the first coupling position A are coupled by the coupling element 11 in such a way that both switching levers 6, 6' are simultaneously by manual actuation by means of the handle 14 of the coupling element 11 with the latter in the switching movement SB ( Fig. 2 ) can be adjusted from switching position I to switching position II and back. Of course, the adjustment can also take place by means of a tool, preferably a screwdriver, which is inserted into one of the receptacles 8, 8 'of the actuating sections 7, 7' of the shift levers 6, 6 '.

Fig. 6 shows the second coupling position B of the coupling element 11 of the coupling device 100 in the first switching position I.

In the second coupling position B, the coupling element 11 is displaced radially out of the first coupling position A by a switching stroke SH in the receptacle 8a of the actuating section 7 of the front switching lever 6. The second coupling position B is thus switched on.

In the second coupling position B, the driver 13 of the coupling element 11 is completely out of its receptacle 8'a of the actuating section 7 'of the rear Shift lever 6 'moved out, whereby the coupling between the shift levers 6, 6' is canceled. In other words, the driver 13 is in the second coupling position B out of engagement with the receptacle 8'a.

In this way, the coupling element 11 can be switched or adjusted linearly in the radial direction with respect to the pivot axis 5a.

Thus, for example, the rear shift lever 6 'can be moved into the position shown in FIG. 3 independently of the front shift lever 6 by means of a tool W, preferably a screwdriver, which is inserted into the receptacle 8' Fig. 7 Switch position II shown can be adjusted.

In a similar way, the front shift lever 6 can be operated manually (or by means of a tool) of the handle 14 of the coupling element 11 independently of the rear shift lever 6 ′ from the position shown in FIG Fig. 8 switch position I shown in the in Fig. 9 Switch position II shown can be adjusted.

The coupling element 11 is fixed by means of the switching pin 12 in the associated receptacle 8 in the first coupling position A and in the second coupling position B by a latching mechanism. This is discussed below in connection with the Figures 10 to 13 described in more detail.

In Figures 10-10b are schematic perspective views of the coupling element 11 of the coupling device 100 of the first embodiment of the isolating terminal 1, 1 'according to the invention Fig. 2 shown.

The switching pin 12 of the coupling element 11 comprises a lug 12a and at least one detent spring 15 with a detent lug 16 as a detent mechanism. The nose 12a is arranged at a distance of approximately one third of the length of the switch pin 12 from the bottom 14a of the handle 14 on the switch pin 12 in the form of a strip, in the installed state it points to the associated stop section 9d and here runs parallel to an edge of the Underside 14a of the handle 14 and in the installed state of the coupling element 11 parallel to the pivot axis 5a.

Here two opposing locking springs 15 are provided approximately in the lower third of the switching pin 12, on the outside of which in a lower area each one outwardly protruding locking lug 16 is integrally formed. The latching lugs 16 protrude in a width direction of the handle 14, the width direction in the installed state of the coupling element 11 running in the direction of the pivot axis 5a.

Each detent spring 15 tapers in its course in the direction of the longitudinal axis of the switching pin 12 towards its respective free end in such a way that a wedge-shaped gap 15b is formed between inner surfaces 15a of the detent springs 15. Behind it there is a U-shaped recess which cannot be seen here and which runs essentially parallel to the stretching direction (see Figure 15a ).

A spreading section 7f can be received in this wedge-shaped intermediate space 15b or in this U-shaped recess. The expansion section 7f can be arranged in the receptacle 8a and interacts with the inner surfaces 15a or with the U-shaped recess in such a way that it presses the locking springs 15 with the locking lugs 16 outwards when the switching pin 12 when the coupling element 11 is inserted the receptacle 8a is inserted. This has the advantage that a holding effect of the latching lugs 16 is reinforced. This is also related to Figures 11a and 11b explained again.

Furthermore, starting from the underside 14a of the handle 14, guide web 12b extending over the entire length of the switching pin 12 and the respective detent spring 15 is integrally formed on the switching pin 12. In the example shown, two opposing guide webs 12b are provided.

The driver 13 also has two opposite guide webs 13 a, which extend over the entire length of the driver on two opposite longitudinal sides of the driver 13.

The handle 14 here has an arrow as a symbol 14b, which points downwards to the shift levers 6, 6 'and thus indicates the insertion direction of the coupling element 11 in the direction of the first coupling position A.

With this principle, an independent connection of adjacent shift levers 6, 6 'is possible from almost any position. The exception is when both shift levers 6, 6 'are in the second switching position II and the coupling element 11 is in the coupling position B. Then the in Fig. 2-9 lying rear shift lever 6 'cannot be moved without moving / adjusting the front shift lever 6.

Figures 11-11b show schematic perspective representations of the coupling device 100 of the first exemplary embodiment of the isolating terminals 1, 1 ′ according to the invention Fig. 2 in different coupling positions.

In the opposite side walls 6a of the shift lever 6 (as well as of the shift lever 6 ', which is not shown but is easy to imagine) in the respective actuating section 7, 7 'a guide recess 17 is formed in each case. The guide recess 17 is a type of elongated hole and forms a lateral opening of the receptacle 8a, 8'a with an upper holding section 17a and a lateral holding section 17b. The upper holding section 17a is formed here from the upper rounding of the guide recess 17. The lateral holding section 17b is introduced approximately in the upper quarter of the guide recess 17 laterally in an approximately semicircular manner.

When the coupling element 11 with the switching pin 12 with its detent springs 15 first is inserted into the receptacle 8a of the switching lever 6, the detent springs 15 are initially pressed together towards one another. With further insertion, the latching lugs 16 are released by the pretensioned latching springs 12 with the support of an expanding locking web 7g, 7'g located in the receptacle 8a (see FIG Fig. 12 ), corresponding to the expansion web 7f, pushed outward again into the guide recesses 17.

In the second coupling position B ( Figure 11a ) the latching lugs 16 are then in positive contact with the upper holding sections 17a of the guide recess 17, the lug 12a of the switching pin 12 resting on the surface 7e of the switching lever 6 at the same time.

In this way, the coupling element 11 is fixed in its longitudinal movement possibility in the second coupling position B by the locking lugs 16 in connection with the upper holding sections 17a of the guide recess 17 preventing the coupling element 11 from being pulled out (with a certain force below the destruction limit) and the nose 12a also opposes a certain holding force when the coupling element 11 is pushed in. In this way, the latching lugs 16 also form a captive function of the coupling element 11.

The holding force of the locking lugs 16 can be strengthened by the expansion section 7f already described above (see FIG Figure 10b ) are reinforced. This increases the captivity function.

To assume the first coupling position A, the holding force of the nose 12a must be overcome. The switching pin 12 of the coupling element 11 can then be pushed further into the receptacle 8a until the lug 12a engages the lateral holding sections 17b of the guide receptacles 17 and in this way defines and maintains the first coupling position A of the coupling element A. This is in Figure 11b shown.

Fig. 12-13 show schematic perspective partial representations in plan view of the actuating sections 8, 8 '; 8a, 8 'of the isolating terminals according to the first embodiment Fig. 2 .

In the transition areas between the receptacles 8 and 8a and 8 'and 8'a lying one behind the other, two opposite guide grooves 8b, 8'b are formed in the sides of the receptacles 8' and 8'a. These guide grooves 8b, 8'b each extend over the entire length of a respective receptacle 8 ', 8'a.

The guide grooves 8b correspond to the guide webs 12b of the switching pin 12 and are in engagement with these when the coupling element 11 is and is inserted into the receptacle. In the same way, the guide grooves 8'b correspond to the guide webs 13a of the driver 13 and are also in engagement with them. The guide grooves 8b, 8'b and guide webs 12b, 13a also form a confusion-free insertion of the coupling element 11 into the receptacles 8a, 8'a. This is over Fig. 13 evident.

Figures 14-16 show schematic representations of a variant of the coupling element 11 according to FIG Figures 10-10b in different coupling positions.

Fig. 14 shows how Fig. 11 the coupling element 11 before insertion. In Fig. 15 is similar to in Figure 11a the second coupling position B is shown. Fig. 16 poses like that Figure 11b represents the first coupling position A.

In this variant, the guide webs 12b extend only over half the length of the switching pin 12. The latching lugs 16 are formed laterally on the free ends of the latching springs 12. The holding sections 17a and 17b of the guide recesses 17 merge into one another.

In the second coupling position B, the Fig. 15 shows, the locking lug 16 is in positive contact with the upper holding portion 17a of the guide recess 17. This is also the case on the other side of the shift lever 6, which is not shown, but is easy to imagine.

Figure 15a shows a cross-sectional view through the actuating section 7 of the shift lever 6 in the second coupling position B of the coupling element 11. The guide webs 12b are received linearly guided in the guide grooves 8b. The expanding locking web 7g is engaged and shows that in the coupling position B, the locking springs 15, which are also referred to as spring legs, cannot evade.

In the first coupling position A, the nose 12a is not only in engagement with the lateral holding section 17b of the guide recess 17, but the nose 12a is also in contact with the upper holding section 17a of the guide recess.

In the examples shown, the switching or adjusting or moving direction of the coupling element 11 is straight in the radial direction with respect to the pivot axis 5a. The switching / adjustment / movement direction can, however, also run rotationally or in a different trajectory. However, this takes place in a different direction than the direction in which the actuation movement of the shift lever 6, 6 'runs around the pivot axis 5a, e.g. also conceivable along a different trajectory.

In the above examples, the coupling element 11 is shown plugged into the switching lever 6 of the front isolating terminal 1 with the switching pin 12. Of course, the coupling element 11 can also be inserted rotated by 180 °, the switching pin 12 being inserted into the receptacle 8'a of the rear isolating terminal 1 'and the driver 13 being inserted into the receptacle 8a of the front isolating terminal 1. In this way, the shift levers 6, 6 'can optionally be switched on to one another.

Not shown, but it is conceivable that the coupling element 11 has a switching pin 12 and two or more drivers 13. These drivers 13 can be arranged on one side to the right or left of the switching pin 12 or evenly or unevenly distributed on both sides. In this way, the switching levers 6, 6 'of e.g. three or four or more isolating terminals 1, 1' can be additionally connected.

All or only some of these additional connections can be made in the first coupling position A. Intermediate positions between the first coupling position A and the second coupling position B are possible, in which the switching levers 6, 6 'of the further isolating terminals 1, 1' are connected.

A not shown, but conceivable variant of the coupling element 11 is that the coupling element 11 has two pins of the same length that are inserted into the receptacles of the adjacent shift levers 6, 6 'and the handle 14 has a separation (e.g. in the middle) that in the connected state, the shift lever 6, 6 ', that is to say in the first coupling position A, is closed. The separation is opened to cancel the connected state of the shift levers 6, 6 'in order to obtain the second coupling position B. The opening takes place in that the separable parts of the handle 14 together with the associated pins in opposite pivoting directions about the axes of the respective pins in the respective receptacles the shift lever 6, 6 'are pivoted apart. The pins remain in the shifter mounts. The separation is positive, for example like two gears or tooth segments that disengage.

In yet another variant of the coupling element 11, the switching pin 12 is rotatably attached to the handle 14. This version is not shown, but in connection with the figures (e.g. Fig. 6, 11 ) easy to imagine. When the coupling element 11 is in the second coupling position B, in this variant the handle 14 together with the driver 13 can be rotated 180 ° around the longitudinal axis of the switch pin 12 remaining in the associated receptacle 8a due to the rotatably attached switch pin 12. This is advantageous if the arrangement 10 has, for example, three isolating terminals 1, 1 ', in which the isolating terminal 1 with the receptacle 8a in which the coupling element 11 with the switching pin 12 is inserted. In this way, by rotating the handle 14 with the driver 13 in the second coupling position B, one of the switching levers 6 'of the adjacent isolating terminal 1' can optionally be connected in the first coupling position A without the coupling element 11 with the switching pin 12 being completely removed from the associated Recording 8a must be pulled out and turned over.

In Fig. 17 is a schematic perspective view of a second embodiment of the inventive isolating terminal 1, 1 'according to FIG Fig. 2 shown with a coupling device 100 according to the invention.

The coupling device 100 here has a coupling element 18 which can be pivoted about an axis 19. The pivotable coupling element 18 is also referred to as a switchable rotation locking element.

Furthermore, it is conceivable, but not further elaborated, that there may be further switch positions / mechanisms which, for example, can bring about a coupling of a central isolating terminal 1, 1 'to isolating terminals 1, 1' arranged next to it on the left or right thereof.

In each of the actuating sections 7, 7 'of the shift levers 6, 6', only the receptacles 8, 8 'for an actuating tool are formed here. An actuating section 7, 7 'protrudes radially between the receptacles 8, 8' and the further end face sections 7b, 7'b of the actuating sections 7, 7 'of the shift levers 6, 6'.

The coupling element 18 is pivotable about the axis 19 on the radially protruding actuating section 7 of the shift lever 6 and is held captive on this. The axis 19 runs at right angles to the pivot axis 5a of the shift lever 6, 6 ', the axis 19 being tangential to an imaginary circle with a center through which the pivot axis 5a of the shift lever 6, 6' lies.

The coupling element 18 can move from a first coupling position A into a second coupling position B (see FIG Figures 19, 19a ) can be switched by pivoting about the axis 19. This is explained in detail below.

Figures 18-21 represent schematic perspective partial views of the coupling device 100 of the second exemplary embodiment Fig. 17 in different coupling positions and switching positions.

Fig. 18 shows the switch position I and in Figure 18a switching position II is shown. The coupling element 18 is in each case in the coupling position A, in which it couples the two shift levers 6, 6 'or locks them together.

The coupling element 18 is a type of elongated hood and comprises a pivot section 18a, a shaft section 18b with the axis 19 and a coupling section 18c. The pivot section 18a and the coupling section 18c are connected by two parallel side walls 18d. The side walls 18d are connected centrally on their upper longitudinal sides by a transverse wall 18e. In the end region of the coupling section 18c, the ends of the side walls 18d are connected by a further transverse wall 18e.

The pivot section 18a is formed from first, rounded ends of the side walls 18d, between which the shaft section 18b is attached.

The shaft section 18b has a disk-shaped solid shaft section 18i and a section which is flattened thereon in the direction of the axis 19. This flattened portion is referred to as a key surface 18j. The key surface 18j here runs parallel to the lower edges of the side walls 18d and points downward when the coupling element 18 is in the first coupling position A.

The coupling section 18c is defined from the second ends of the side walls 18d and the transverse wall 18f.

The distance between the parallel side walls 18d corresponds to a thickness of the actuating sections 7, 7 'protruding radially from the shift levers 6, 6' such that the free end regions of the actuating sections 7, 7 'can each be received between the side walls 18d of the coupling element 18.

The pivot section 18a and the coupling section 18c thus form two interconnected hood sections.

The shaft section 18b of the pivot section 18a of the coupling element 18 is received in a receptacle 20 of the protruding actuation section 7 so as to be pivotable. This is explained in detail below. An inside diameter of the receptacle 20, 20 ′ corresponds to an outside diameter of the disk-shaped solid shaft section 18i of the shaft section 18. In this way, the coupling element 18 is pivotably attached to the protruding actuating section 7.

In the first coupling position A, which is in Fig. 17 , 18 and 18a is shown, the coupling element 18 is pivoted over the radially protruding actuating section 7 'of the adjacent shift lever 6' and coupled to it in a form-fitting manner. The coupling section 18c surrounds the radially protruding actuating section 7 'of the adjacent shift lever 6' like a hood. In the first coupling position A, a longitudinal axis of the coupling element 14 runs parallel to the pivot axis 5a of the shift levers 6, 6 '. At the same time, the coupling section 18c is fixed in the coupling position A on the radially protruding actuating section 7 'with a latching device, which will be described below.

Lever projections 18g are formed on the upper end regions of the side walls 18d of the coupling section 18c. By means of the lever projections 18g as handle sections, the coupling element 18 can be pivoted manually from the first coupling position A into the second coupling position B by lifting the coupling section 18c and pivoting the coupling element 18 about the shaft section 18b and its axis 19. A pivot angle between the two coupling positions A and B is 90 ° here.

In the second coupling position B, the coupling element 18 or its longitudinal axis is perpendicular to the actuating section 7 of the shift lever 6 and radially with respect to the pivot axis 5a. The coupling element 18 is held in this second coupling position B by a latching device or a latching mechanism, which will be explained in more detail below.

In Fig. 19 the switching position I is shown and in Figure 19a switching position II is shown. The coupling element 18 is in the coupling position B, in which the two shift levers 6, 6 'are neither coupled nor locked with one another. Fig. 19 also shows the actuation section 7 'of the shift lever 6', which is free in the second coupling position B of the coupling element 18. This actuating section 7 'is designed in exactly the same way as the other actuating section 7 of the other shift lever 6. In other words, the shift levers 6, 6' and the actuating sections 7, 7 'are the same. No special designs are required.

The actuating section 7, 7 'of the shift lever 6, 6' of the second embodiment according to Fig. 17 is in Figures 22-22a shown in schematic perspective views. Figure 22b shows a side view of the operating section 7.

Fig. 23-27 show schematic representations of the coupling element 18 and at least partial representations of the actuating section 7, 7 'of the second exemplary embodiment according to FIG Fig. 17 .

The actuating section 7, 7 'is provided with a receptacle 20, 20' in its upper end region. The receptacle 20, 20 'is circular-cylindrical, has an axis 19a, 19'a and extends at right angles to the pivot axis 5a of the shift levers 6, 6'. The axis 19a, 19'a forms a tangent to an imaginary circle, through the center of which the pivot axis 5a runs.

The inner wall of the receptacle 20, 20 'is interrupted by an opening 21, 21' running parallel to the direction of the axis 19a, 19'a. The opening 21, 21 'has two areas with different opening widths. The first area (in Fig. 22 arranged on the left) corresponds to about a quarter of the length of the opening 21, 21 'and has a recess 20a, 20'a with an opening width which corresponds to the diameter of the receptacle 20, 20'. The second area (in Fig. 22 adjoining the first area on the right) extends over a length of approximately three quarters of the total length of the receptacle 20, 20 'and has a protruding longitudinal edge LR. The opening width of this second area with the longitudinal edge LR is smaller than the diameter of the receptacle 20, 20 '. The longitudinal edge LR of the opening 21, 21 'has an undercut 20b, 20'b

During assembly, the coupling element 18 is inserted into the receptacle 20 of the actuating section 7 of the shift lever 6 with the shaft section 18b of the pivoting section 18a through the opening 21. This is only possible in a certain mounting position C, which is shown in Figures 20-21 is shown. The coupling element 18 is at an angle of approximately 30 ° with respect to the pivot axis 5a. The assembly position is thus about 150 ° to the first coupling position A in relation to the axis 19. When the coupling element 18 is in the assembly position C, the key surface 18j points upwards. In this position there is an onset of the shaft section 18b into the receptacle 20 of the actuating section 7 due to the flattened key surface 18j of the shaft section 18b, since the flattened key surface 18j reduces the outer dimension of the shaft section 18b so that the shaft section 18b is easily pushed into the receptacle 20, 20 'due to the smaller opening width can be. The disk-shaped solid shaft section 18i fits with its diameter through the first region of the opening 21, 21 'into the recess 20a, 20'a, which is provided for it.

When the coupling element 18 is inserted in the mounting position C into the receptacle 20, 20 'in this way, what Fig. 21 shows, the coupling element 18 is pivoted into the second coupling position B. In this second coupling position B, in the first coupling position A and in all other positions except for the assembly position C, the coupling element 18 is held captive via the shaft section 18b in the receptacle 20 through the undercut 20b.

In the assembled state of the coupling element 18, the axis 19 of the shaft section 18a of the coupling element 18 and the axis 19a of the receptacle 20 run coaxially to one another.

The coupling element 18 has two locking positions. The first latching position is formed in the first coupling position A parallel to the pivot axis 5a of the shift levers 6, 6 'by a latching device or by a latching mechanism. This latching device comprises at least one spherical segment-shaped projection 18h. In the example shown, a spherical segment-shaped projection 18h on the inner sides of the side walls 18d in the area of the coupling section 18c of the coupling element 18 engages with the ends of the receptacle 20 'of the actuating section 7' of the adjacent shift lever 6 '. It is also possible that only one spherical segment-shaped projection 18h or also several are provided.

The second latching position of the coupling element 18 is the second coupling position B perpendicular to the pivot axis 5a of the shift lever 6, a latching device or a latching mechanism with a protruding section and a corresponding molded section being provided. In the example shown here in part, this latching device comprises an indentation 7h, 7'h in the form of an elongated groove as a section molded into one side of the actuating section 7, 7 'and a web 18k as a protruding section on an inside of the side wall 18d of the coupling element 18 in the area of the pivot section 18a. The web 18k is formed in the end region of the side wall 18d of the coupling element 18 in the pivot section 18a perpendicular to the longitudinal edges of the side walls 18d. This is in Figures 18 and 18a easy to see where the bridge 18k in the first coupling position A is perpendicular to the pivot axis 5a and also perpendicular to the indentation 7h. In the second coupling position B, the web 18k is in engagement with the indentation 7h. This is in Fig. 25 to recognize. The web 18k runs parallel to the pivot axis 5a and parallel to the indentation 7h.

This latching device for the second coupling position B can in a further example have a not shown but easily imaginable projection (or two or more, similar to the projections 18h) on the inner sides of the side walls 18d in the pivot section 18a of the coupling element 18, which / which in the second coupling position B is / are in engagement with one end of the opening 21, 21 'and / or one end of the receptacle 20, 20' between the longitudinal edge LR and a lower longitudinal edge.

If another adjacent gear lever (e.g. in Fig. 21 located in front of the front shift lever 6), the coupling element 18 cannot be pivoted into the assembly position C and cannot be dismantled. This is in Fig. 28 shown.

The direction of movement of the coupling element 18 in this embodiment is rotatory about the axis 19. The movement can also be designed in a rotational manner by a different type of trajectory, but in a different plane than the actuation plane of the shift lever 6. The movement is also conceivable along a different trajectory .

Fig. 23 13 is a side view of the coupling element 18 in the assembly position C in relation to the actuating section 7 of the shift lever 6 shown next to it. The axis 19 here runs outside an imaginary longitudinal axis of the coupling element 18.

In Fig. 24 shows a cross section through the coupling element 18 in the area of the pivot section 18a through the shaft section 18b. The shaft section 18b, the disk-shaped solid shaft section 18i and the side walls 18d are formed in one piece here, for example from a suitable plastic material. The key surface 18j is arranged here between the left side wall 18d and the disk-shaped solid shaft section 18i. A reduction in the outer dimensions of the shaft section 18b in relation to the solid shaft section 18i can be clearly seen.

Fig. 25 shows a side view of the actuating section 7 of the shift lever 6 and the coupling element 18 located in the second coupling position B. From the inner sides of the side walls 18d in the area of the coupling section 18b of FIG Coupling element 18, the spherical section-shaped projections 18h of the latching device protrude into the interior of the coupling section 18c.

In Fig. 26 the coupling element 18 of the latching device is in the first coupling position A. A sectional view along line XXVII through the coupling section 18c is shown in FIG Fig. 27 shown, wherein the projections 18h with the open ends of the receptacle 20 'of the actuating portion 7' of the adjacent shift lever 6 'in engagement and form a latching position.

In Fig. 27 an additional latching device is indicated for the first coupling position A, which (like the latching device for the second coupling position B described above) has a protruding section as a web 18'k and a molded-in section as an indentation 7'h of the actuating section 7 'of the shift lever 6' having. The web 18'k is arranged in the coupling section 18c of the coupling element 18 on its side wall 18d parallel to its longitudinal edge. In the first coupling position A, the web 18'k runs parallel to the pivot axis 5a and parallel to the indentation 7'h and is in engagement with the indentation 7'h.

The webs 18k, 18'k and the associated indentations 7h, 7'h can of course also be arranged at other angles to the pivot axis 5a for the two coupling positions A, B. They can also have other shapes, e.g. spherical segment, square, oval shape, cross shape, etc. Of course, these latching devices for the coupling positions A, B can also be expanded for further coupling positions of the coupling element 18.

With this principle of the coupling element 18 of the second embodiment, the independent connection of adjacent shift levers 6, 6 'is possible from any position.

Figures 28-29 show schematic partial representations of coupling devices 100 of isolating terminals 1, 1 ′ according to the second exemplary embodiment according to FIG Fig. 17 .

Fig. 28 shows two pairs of shift levers 6, 6 '; 6, 6 ', in which the two front shift levers 6, 6' with the coupling element 18 of the coupling device 100 are shown in the coupling position A. The coupling element 18 of the other coupling device 100 is in the second coupling position B.

The coupling element 18 can also be designed for more than two shift levers 6, 6 '. Here shows Fig. 29 an example of four shift levers 6, 6 '. The coupling element 18 is made correspondingly longer. The areas of the coupling element 18, which couple the actuating sections 7 'of the middle shift levers 6' can also be provided with corresponding projections 18h.

Figures 30-33a represent schematic views of a coupling device 100 of a third exemplary embodiment of isolating terminals 1, 1 '.

This coupling device 100 comprises a rotatable or pivotable coupling element 22, 22 'which is arranged in a receptacle 23, 23' in the actuating section 7, 7 'of a shift lever 6, 6'.

The receptacle 23, 23 'is to the side section 7d, 7'd (see Fig. 1 ) of the actuating section 7, 7 'is opened via a slot 25, 25'. Towards the other side section 7c, 7'c, the receptacle 23, 23 'is connected by an intermediate wall 27, 27' from a further receptacle 24, 24 ', which in turn faces the other side section 7c, 7'c of the actuating section 7, 7' is also open through a slot 25a, 25'a.

The coupling element 22, 22 'is in Figures 33-33a shown in perspective from different views and installed. It comprises a cylindrical body 22a, 22'a with a pivot axis 22c, 22'c. An arm with a hook section 22b, 22'b is attached radially to the body 22a, 22'a. The body 22a, 22'a has an actuating section 22d, 22'd, here in the form of a slot, for a suitable tool, for example a screwdriver, on one end face. The other end face of the body 22a, 22'a is provided with a centrally formed bearing projection 22f, 22'f, which here is a spherical section. A lug 22e, 22'e (a cam) is attached on the outside of the body 22a, 22'a diametrically to the integrally formed hook section 22b, 22'b. This nose 22a, 22'a extends from the end face of the body 22a, 22'a with the bearing section 22f, 22'f parallel to the pivot axis 22c, 22'c to about half the length of the body 22a, 22'a.

The receptacle 23, 23 'corresponds to the shape of the coupling element 22, 22' and is closed in its lower section with a curved receiving wall 27a, 27'a with an undercut 23a, 23'a in the area of the slot 25, 25 ' The radius corresponds to the radius of the body 22a, 22'a of the coupling element 22, 22 '.

The receptacle 24, 24 'corresponds to the hook section 22b, 22'b of the coupling element 22, 22' and has an undercut 24a, 24'a in its lower area, which is intended for engagement with the hook section 22b, 22'b of the coupling element 22 , 22 'is provided in the slot 25a, 25'a.

The receptacles 23, 23 'and 24, 24' are closed with the end face sections 7a, 7'a and 7b, 7'b of the actuating sections 7, 7 ', wherein in the area of the body 22a, 22'a of the coupling element 22, 22' In the end face section 7b, 7'b openings 26, 26 'for access to the slots 22d, 22'd of the coupling element 22, 22' for pivoting the same are formed, and in the opposite end face section 7a, 7'a bearing sections 29, 29 'for supporting the bearing projections 22f, 22'f of the coupling elements 22, 22' are introduced. In this way, the coupling element 22, 22 'guided by the bearing sections 29, 29' and the lower receiving wall 27a, 27'a and the intermediate wall 27, 27 'can be pivoted about the pivot axis 22c, 22'c in the receptacle 23, 23' .

The pivot axis 22c, 22'c is at right angles to the pivot axis 5a of the shift levers 6, 6 'and tangential to an imaginary circle with a center point through which the pivot axis 5a of the shift levers 6, 6' runs.

The coupling element 22, 22 'is clipped from the side section 7d, 7'd through the slot 25, 25' into the receptacle 23, 23 ', the undercut 23a, 23'a and the spherical section-shaped bearing projection 22f, 22'f the Hold the coupling element 22, 22 'captive in the receptacle 23, 23'.

Fig. 30 shows two coupling elements 22, 22 'in adjacent actuation sections 7, 7' of adjacent shift levers 6, 6 'in the first coupling position A. The hook sections 22b, 22'b are inside the receptacles 23, 23'.

Figure 30b shows the receptacles 23, 23 'closed by the side sections 7b, 7'b; 24, 24 'with the openings 26, 26', through which the coupling elements 22, 22 'each about their pivot axes 22c, 22'c from the first coupling position in engagement with the actuating sections 22d, 22'd with a tool, preferably a screwdriver A can be pivoted into the second coupling position B and back.

The openings 26, 26 'are provided here with additional stops 26a, 26'a for the tool in order to limit pivoting of the coupling element 22, 22' to the coupling positions A and B.

In Figure 30a and 30c the second coupling positions B are shown. The coupling elements 22, 22 'are pivoted such that the hook sections 22b, 22'b extend through the slots 25, 25' and with the receptacle 24 of the adjacent one Actuating portion 7, 7 'are engaged, whereby a coupling of the adjacent shift lever 6, 6' is made possible.

It is also conceivable that two opposing hook sections 22b, e.g. in the form of an anchor, are provided, the coupling element 22, 22 'being pivotable in two different pivoting directions, whereby it assumes a middle position in the second coupling position B.

In Fig. 31 only one coupling element 22 'is pivoted into the second coupling position B, the other coupling element 22 has remained in the first coupling position A. The coupling elements 22, 22 'can thus be switched or adjusted or pivoted independently of one another.

Thus, independent movements of the shift levers 6, 6 'are possible as soon as the coupling element 22, 22' on the respective adjacent shift lever 6, 6 'is switched to the first coupling position A, i.e. does not lock with the adjacent shift lever (s) 6, 6' .

The underside of the receiving wall 27a, 27'a is in Figure 31a each shown with a recess 28, 28 '.

Figure 31b shows the coupling elements 22, 22 'from Figures 31 and 31a without side sections. In Figure 31c are only the open receptacles 23, 23 '; 24, 24 'shown without coupling elements 22, 22'.

The intermediate wall 27, 27 'also has a recess 28a, 28'a.

The recesses 28, 28 '; 28a, 28'a correspond in their shape to the nose 22e, 22'e of the coupling element 22, 22 '.

How out Figure 31a and 31b As can be clearly seen, the nose 22e of the coupling element 22 located in the first coupling position A is in engagement with the recess 28 in the lower receiving wall 27a and thus forms a latching of the coupling element 22 in the first coupling position A.

The nose 22'e of the other coupling element 22 ', which is in the second coupling position B, is in engagement with the other recess 28'a in the intermediate wall 27. This enables the coupling element 22' to be locked in the second coupling position B.

The recesses 28, 28 'and 28a, 28'a are in Fig. 32 shown enlarged together with the bearing sections 29, 29 '

The areas of the actuating sections 7, 7 'of the shift levers 6, 6' with the molded-in receptacles 23, 23 '; 24, 24 'are shown here in the form of a box. These box-shaped areas are made in one piece with the shift levers 6, 6 '.

In another embodiment, these box-shaped areas or receiving sections can also be designed as separate parts which are attached to the shift levers 6, 6 'in a suitable manner. Such an attachment can be, for example, as a clip connection, tongue and groove connection, screw connection, plug connection or the like. be trained.

In Figures 34-40c schematic views of switching status displays 30 are shown.

The respective switch position I, II, i.e. the connection position and the disconnected position of the switch levers 6, 6 'is visibly indicated by the switch status display 30.

This is done in such a way that on the one hand a first display section 31 is arranged on the movable shift lever 6, 6 'or the actuation section 7, 7', and on the other hand a second display section 32 that matches this is attached to the stationary housing. In the first switching position I (“closed”), these two display sections 31 and 32 are combined in such a way that “closed” symbols are clearly visible. And in the second switch position II ("separated") these symbols are separated, from which a separation can be clearly recognized.

• Geometrischer Bruch
  (z.B. getrennte/zusammengeführte zwei Halbkreise - geschlossener Kreis
• Gabel und Anschlusspunkt
• Pfeilartig ausgebildete Geometrieelemente, die in der Schaltstellung I nicht sichtbar sind.
• Schaltsymbole: Gabel mit Anschlusspunkt oder Schaltersymbol offen/geschlossen
• Oberflächen in Schaltstellung I bündig
• Elemente können farbig sein, um Zusammengehörigkeit darzustellen, Kontrast oder Ampelfunktion zu bieten.

The following geometric solutions are possible for this:

• Geometric break
  (e.g. separated / merged two semicircles - closed circle
• Fork and connection point
• Geometrical elements designed like arrows, which are not visible in switching position I.
• Switching symbols: fork with connection point or switch symbol open / closed
• Surfaces in switch position I flush
• Elements can be colored to show what they belong together, to offer contrast or a traffic light function.

Different examples are in Figures 34-40c shown.

Figures 34-34a show the switch position II, where Figures 34b-34c show the switch position I. Here, the movable display section 31 is a fork-shaped circular arc which encloses the stationary display section 32, which is designed as a protruding circular cylinder, in the switching position II.

Show the geometric inversion Figures 35-35a in switch position II and Figures 35b-35c in switching position I. The circular cylinder is now the movable display section 31 which, in switching position I, is enclosed by a corresponding receptacle as a stationary display section 32.

Figures 36-36c show the separated two semicircles, which are then brought together in switch position I as a closed circle.

Figures 37-37c is a variant of the execution according to Figures 35-35c , wherein the stationary display section 32 has an upwardly protruding symbolism, which represents the switching state I as a plugged-together plug connection circuit symbol.

Figures 38-38c and Figures 39-39c each show a cut contour, which can be recognized as joined in switching state I.

Figures 40-40a shows a colored circuit symbol of an open switch as a movable display section 31. The stationary display section 32 is an opening in the form of the circuit symbol for a closed switch. In the switch position I, the circuit symbol of the open switch can no longer be seen, the opening being represented in the form of the circuit symbol for the closed switch by the colored background of the movable display section 31 located below.

The switching status display can also be designed with a kind of traffic light function.
