Description

[0001] The present invention relates to a disconnect terminal with switching status indicator.

[0002] These types of disconnect terminals are used in various applications.

[0003] DE 44 44 551 A1 describes a current transformer disconnect terminal with a switching element in the form of an angle-adjustable contact disc, which, by means of a contact follow-through, ensures that the secondary side of a connected current transformer can never be open when the current path through the terminal is opened or closed. The contact disc is angle-adjustable about a pivot axis by means of a pivot lever. The actuation of the current transformer disconnect terminal, i.e., the manual pivoting of the lever from one switching position to the other for several immediately adjacent disconnect terminals en bloc, can be achieved by inserting a coupling pin into the handle knobs of the pivot levers of the immediately adjacent disconnect terminals.

[0004] DE 44 44 556 A1 relates to switchable terminal blocks with a switching lever handle made of insulating material. The handle has two viewing surfaces, one of which, in each of the two switching positions of the lever, alternately faces the operator's line of sight and the other faces away from the operator's line of sight in the same switching position. The handles of immediately adjacent terminal blocks can be coupled by means of a transparent cap that covers two or more handles.

[0005] DE 10 2008 014 176 B4 describes a terminal block and a linear disconnect switch with a disconnecting blade for pivotable arrangement in a terminal housing of the terminal block. The terminal housing contains a busbar consisting of two sections and two conductor connection elements for connecting a conductor to each section of the busbar. In a first position of the disconnecting blade, the two sections are connected to each other, and in a second position of the disconnecting blade, they are separated from each other. The disconnecting blade is partially enclosed in an insulating housing. The linear disconnect switch can be operated not only with a screwdriver, which is inserted into an operating slot in the insulating housing, but also with a switch linkage having two arms and a handle section connecting the arms.This allows two longitudinal disconnect switches of two adjacent terminal blocks to be operated simultaneously, for which one leg is inserted into the operating shaft of a longitudinal disconnect switch.

[0006] DE 197 42 785 C1 discloses a slim relay module, designed for space-saving, modular installation, in the form of a DIN rail device. The module comprises a housing open towards the operator side, containing fixed contacts, e.g., spring-loaded bushings, spaced transversely to its narrow edges. A knife-blade-like isolating bar serves to selectively connect or disconnect these contacts. The housing opening can be closed with a cover. The housing cover is pivotally mounted on the housing about an axis extending towards the narrow edges and carries the isolating bar on its underside. Opening the housing cover thus automatically causes the electrical isolation of the fixed contacts at a disconnect point in an internal electronic circuit.

[0007] The cover has a semicircular recess on one side at its movable end, which, when the cover is closed, engages with a corresponding semicircular projection on one side of the terminal housing. The sides of the terminals are not visible in a row arrangement. The semicircular opening of the cover and the semicircular projection on the side of the terminal housing form a latching mechanism for the cover when it is closed.

[0008] The familiar disconnect terminals have proven their worth in themselves.

[0009] However, it is desirable to further develop these disconnect terminals in such a way that the switching position can be easily and quickly identified.

[0010] The invention aims to solve this problem. It achieves this goal through the subject matter of claims 1 and 2.

[0011] A disconnect terminal according to the invention comprises at least one switching lever, wherein the switching lever is adjustable independently of any other switching lever from a first switching position to at least a second switching position and back. The disconnect terminal has a switching status indicator with a movable display section and a stationary display section, wherein the switching status indicator visibly displays the respective switching position or at least one further switching position of the switching lever, wherein in the first switching position these two display sections are combined in such a way that a "closed" symbol is clearly recognizable, and wherein in the second switching position this symbol is separated, from which a separation is clearly recognizable.

[0012] This enables a conveniently simple and unambiguous display of switching states.

[0013] It should be noted that such a switching status indicator can also be used for other terminal types, which, for example, have coupling elements.

[0014] An embodiment not belonging to the invention provides that at least the first switching position is indicated by a cover and / or by making a section of the display visible, and at least the second switching position is indicated by making a section of the display visible and / or by covering it. This results in a compact design.

[0015] In In a further non-inventive embodiment, the switching status indicator advantageously supports recognizability through color, symbols and / or geometry.

[0016] This is advantageous because it allows for detection even from a greater distance. Further advantageous embodiments are described in the remaining dependent claims.

[0017] In the embodiment according to the invention, one of the two display sections forms a forked circular arc and the other of the two display sections forms a circular cylinder, wherein the circular arc of one display section, in the first switching position, encloses the circular cylinder of the other display section as a closed symbol and, in the second switching position, is separated from the circular cylinder of the other display section, wherein each display section has an upwardly projecting symbol, and wherein the display sections are attached outside a housing of the disconnect terminal on the one hand to the movable switching lever or an actuating section and on the other hand to the stationary housing of the disconnect terminal.

[0018] An alternative disconnect terminal according to the invention has at least one switching lever, wherein the switching lever is adjustable from a first switching position to at least a second switching position and back, wherein the disconnect terminal has a switching status indicator with a movable display section and a stationary display section, wherein the switching status indicator visibly displays the respective switching position or at least one further switching position of the switching lever.In the first switching position, these two display sections are combined in such a way that a "closed" symbol is clearly visible, and in the second switching position, this symbol is separated, from which a separation is clearly recognizable, wherein the two display sections each form a semicircle, wherein these semicircles are joined together as a closed circle in the first switching position and separated from each other in the second switching position, wherein each display section has an upwardly projecting symbol, and wherein the display sections are attached outside a housing of the disconnect terminal on the one hand to the movable switching lever or an actuating section and on the other hand to the stationary housing of the disconnect terminal.

[0020] The terms "top", "bottom", "left", "right" refer to the respective arrangement of the components in the figures.

[0021] Fig. 1 shows a schematic perspective view of a typical disconnect terminal 1 in an arrangement 10, which here has two disconnect terminals 1, 1' (of course there can also be more than two disconnect terminals 1, 1').

[0022] To distinguish between the two disconnect terminals 1, 1', the reference numeral of the rear disconnect terminal 1' shown in the figures, including the reference numerals of its individual parts / sections, is marked with an apostrophe. The description will separately highlight the different features of the front and rear disconnect terminals 1, 1'.

[0023] Such disconnect terminals 1, 1' are also referred to as connectable disconnect terminals 1, 1', measuring disconnect terminals or series disconnect terminals.

[0024] The disconnect terminal 1, 1' comprises a housing 2, 2' with a first connection section 3, 3', a second connection section 4, 4' and a disconnect section 5, 5' arranged centrally between them.

[0025] In the first connection section 3, 3', a first terminal section (not described in detail) is arranged for connecting an electrically conductive conductor (not shown). The first terminal section is connected to a first conductor rail 3a, which extends into the separation section 5 via an unlabeled connecting section.

[0026] Similarly, in the second connection section 4, 4', a second terminal section (not shown) for connecting another electrically conductive conductor (not shown) is arranged, mirroring the first connection section 3, 3'. The second terminal section is connected to a second conductor rail 4a, which extends into the disconnect section 5, 5' via an unlabeled connecting section.

[0027] The connecting sections of the conductor rails 3a and 4a are operatively connected to a switching device (not shown) in the disconnecting section 5, 5'. The switching device has a switching lever 6, 6' which can be adjusted from a first switching position I to a second switching position II and back. In doing so, the switching lever 6, 6' pivots about a pivot axis 5a in a switching movement SB.

[0028] The pivot axis 5a runs perpendicular to the unlabelled side surfaces of the housing 2, 2' of the disconnect terminal 1, 1'.

[0029] In the first switching position I, also referred to as the connection position, the switching device electrically connects the two connection sections, thus electrically connecting the first conductor rail 3a and the second conductor rail 4a, so that the first terminal section is electrically connected to the second terminal section. In this position, the upper part of the switching lever 6 with an actuating section 7 rests against a stop section 9 of the housing 2, as shown in Fig. 1 shown for the front disconnect terminal 1.

[0030] In the second switching position II, which is also called the disconnect position, the two connecting sections are separated and isolated from each other, i.e. the electrically conductive connection of the two connecting sections and thus of the conductor rails 3a and 4a is removed or separated, whereby the conductor rail 3'a remains electrically connected to the switching lever 6'.

[0031] In this second switching position II, the actuating section 7' ​​of the shift lever 6' rests against a further stop section 9'a of the housing 2, as shown in Fig. 1 The rear disconnect terminal 1' is shown. Furthermore, in switching position II, a cross-bridge (not shown in detail) is contacted such that, in the case of switching position II of all adjacent disconnect terminals, the terminals 3 and 3' are conductively connected / short-circuited to each other via this cross-bridge. The cross-bridge is provided with contacts similar to those of the conductor rails 3a and 4a towards the switching lever.

[0032] In the example shown in Fig. 1 In the actuation section 7, 7' a receptacle 8, 8' is formed from above in a radial direction with respect to the pivot axis 5a.

[0033] The shift lever 6, 6' is operated manually and / or with a suitable tool, e.g. a screwdriver, engaging with the receptacle 8, 8'.

[0034] The actuating section 7, 7' of the shift lever 6, 6' has two opposing side sections. First, there are end sections 7a, 7'a, which point to the connection sections 4, 4' of switching position I. Opposite these are end sections 7b, 7'b, which point to the connection sections 3, 3' of switching position II. Perpendicular to these are side sections 7c, 7'c, whose surfaces are perpendicular to the pivot axis 5a. Opposite these are side sections 7d, 7'd.

[0035] In Fig. 2 Figure 10 shows a schematic perspective view of a first example of a disconnect terminal 1, 1' not according to the invention, with a coupling device 100. The arrangement 10 has two adjacent disconnect terminals 1, 1'.

[0036] The coupling device 100 serves to couple at least two adjacent switching levers 6, 6' of two adjacent disconnect terminals 1, 1'.

[0037] The term "coupling" means that at least two adjacent shift levers 6, 6' are locked to each other or connected in such a way that they can be moved together from shift position I to shift position II and back. When the "coupling" is released, the shift levers 6, 6' are separated from each other and can be operated independently.

[0038] At the in Fig. 1 At the standard disconnect terminal 1, 1' shown, a type of clip-type connector with two pins is inserted into the receptacles 8, 8' of the shift levers 6, 6' of the disconnect terminals 1, 1'. Using this clip-type connector, the two shift levers 6, 6' can be connected and adjusted together. Separate adjustment of the shift levers 6, 6' independently of each other is only possible when the clip-type connector has been removed.

[0039] The coupling device 100 of the example according to Fig. 2 In contrast, it includes a switchable or adjustable coupling element 11, which, as shown here, couples two shift levers 6, 6' together, but can also, as is easily imaginable, be designed for more than two shift levers 6, 6'.

[0040] The term "switchable" refers to the 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 be rotary and / or linear.

[0041] It is also conceivable, though not elaborated upon, that there may be further switching positions / mechanisms that could, for example, couple a central disconnect terminal to disconnect terminals located to its left or right. This is not shown, but easily imaginable.

[0042] In the actuating sections 7, 7' of the shift levers 6, 6', two adjacent receptacles 8, 8a and 8', 8'a are formed in the circumferential direction with respect 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'.

[0043] In 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 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'.

[0044] The coupling element 11 is inserted into one of the shift levers 6, 6' and held captive by a locking mechanism. Furthermore, the coupling element 11 is slidably guided within this shift lever 6, 6' and can be moved from a first coupling position A to a second coupling position B (see Fig. 4 , 6, 7 ) will be switched on. This will be explained in more detail below.

[0045] Fig. 3-9 schematic perspective partial views of the coupling device 100 are shown. Fig. 2 in different coupling positions A, B and switching positions I, II.

[0046] In Fig. 3 The coupling element 11 is shown in a so-called pre-assembly position before being inserted into the receptacles 8, 8' of the shift levers 6, 6'. The shift levers 6, 6' are both in switching position I against the stop sections 9, 9' of the respective housing 2, 2'.

[0047] 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 a lower surface 4a of the handle 14. The length of the switching pin 12 is more than twice the length of the driver 13. The switching pin 12 and the driver 13 are arranged side by side with respect to the pivot axis 5a.

[0048] Fig. 4 shows the disconnect terminals 1, 1' with the switching levers 6, 6' and the coupling device 100 in switching position I, with switching position II in Fig. 5 is shown.

[0049] The coupling element 11 is inserted here into the receptacles 8a, 8'a of the actuating sections 7, 7' of the shift levers 6, 6' linearly in a radial direction with respect to the pivot axis 5a, such that the long shift pin 12 in the receptacle 8a of the shift lever 6 of the Fig. 2 bis 9 the front disconnect terminal 1 shown is received, and the short driver 13 is received in the receptacle 8'a of the shift lever 6' of the in Fig. 2 bis 9 The rear disconnect clamp 1' shown is received or engaged with it. 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, also referred to as a locking mechanism, engages the shift lever 6, 6' (mechanically).

[0050] In this way, the shift levers 6, 6' are coupled in the first coupling position A by the coupling element 11 such that both shift levers 6, 6' can be simultaneously engaged in the shifting movement SB by manual actuation using the handle 14 of the coupling element 11. Fig. 2 ) can be adjusted from switching position I to switching position II and back. Of course, the adjustment can also be made using 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'.

[0051] Fig. 6 shows the second coupling position B of the coupling element 11 of the coupling device 100 in the first switching position I.

[0052] The coupling element 11 is moved radially in the receptacle 8a of the actuating section 7 of the front shift lever 6 from the first coupling position A by a switching stroke SH in the second coupling position B. This engages the second coupling position B.

[0053] In the second coupling position B, the driver 13 of the coupling element 11 is completely disengaged from its receptacle 8'a of the actuating section 7' ​​of the rear shift lever 6', thereby releasing the coupling between the shift levers 6 and 6'. In other words, in the second coupling position B, the driver 13 is disengaged from the receptacle 8'a.

[0054] In this way, the coupling element 11 can be switched or adjusted linearly in the radial direction with respect to the pivot axis 5a.

[0055] For example, the rear shift lever 6' can be moved independently of the front shift lever 6 into the Fig. 7 The switch position shown, II, can be adjusted.

[0056] Similarly, the front shift lever 6 can be disengaged from the rear shift lever 6' by manually (or by means of a tool) actuating the handle 14 of the coupling element 11. Fig. 8 shown switch position I in the Fig. 9 The switch position shown, II, can be adjusted.

[0057] The coupling element 11 is fixed in the corresponding receptacle 8 by means of the switching pin 12 in the first coupling position A and in the second coupling position B by means of a detent mechanism. This will be discussed in more detail below in connection with the Figuren 10 bis 13 described in more detail.

[0058] In Fig. 10-10b are schematic perspective representations of the coupling element 11 of the coupling device 100 of the first example of the disconnect terminal 1, 1' according to Fig. 2 shown.

[0059] 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 lug 12a is molded onto the switching pin 12 in a strip-like manner at a distance of approximately one-third of the length of the switching pin 12 from the underside 14a of the handle 14. In the installed state, it points towards the associated stop section 9d and runs parallel to an edge of the underside 14a of the handle 14. In the installed state of the coupling element 11, it runs parallel to the pivot axis 5a.

[0060] Approximately in the lower third of the switching pin 12, two opposing detent springs 15 are provided, each with an outwardly projecting detent lug 16 formed on its outer side in a lower region. The detent lugs 16 project in a lateral direction of the handle 14, with the lateral direction running in the direction of the pivot axis 5a when the coupling element 11 is installed.

[0061] Each detent spring 15 tapers towards its respective free end in the direction of the longitudinal axis of the switching pin 12, such that a wedge-shaped gap 15b is formed between the inner surfaces 15a of the detent springs 15. Behind this is a U-shaped recess, not visible here, which runs essentially parallel to the direction of extension (see Fig. 15a ).

[0062] A spreading section 7f can be received in this wedge-shaped gap 15b or in this U-shaped recess. The spreading 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 pushes the detent springs 15 with the detent lugs 16 outwards when the switching pin 12 is inserted into the receptacle 8a during the insertion of the coupling element 11. This has the advantage of increasing the holding effect of the detent lugs 16. This is also in connection with Fig. 11a und 11b explained again.

[0063] Furthermore, a guide rib 12b extending from the underside 14a of the handle 14 along the entire length of the switching pin 12 and the respective detent spring 15 is formed on the switching pin 12. In the example shown, two opposing guide ribs 12b are provided.

[0064] The driver 13 also has two opposing guide webs 13a, which extend over the entire length of the driver on two opposite longitudinal sides of the driver 13.

[0065] The handle 14 here has an arrow as symbol 14b, which points downwards towards the shift levers 6, 6' and thus indicates the insertion direction of the coupling element 11 towards the first coupling position A.

[0066] This principle allows for independent switching of adjacent shift levers 6, 6' 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. In that case, the Fig. 2-9 The rear gear lever 6' cannot be moved without moving / adjusting the front gear lever 6.

[0067] Fig. 11-11b schematic perspective views of the coupling device 100 of the first example of the disconnect terminals 1, 1' are shown according to Fig. 2 in different coupling positions.

[0068] In the opposing side walls 6a of the shift lever 6 (as well as of the shift lever 6', which is not shown but easily imaginable) in the respective actuating section 7, 7', a guide recess 17 is formed. The guide recess 17 is a type of elongated hole and forms a lateral opening of the receptacle 8a, 8'a with an upper retaining section 17a and a lateral retaining section 17b. The upper retaining section 17a is formed here by the upper curve of the guide recess 17. The lateral retaining section 17b is inserted laterally in approximately a semicircular shape in the upper quarter of the guide recess 17.

[0069] When the coupling element 11, with the switching pin 12 and its detent springs 15 leading the way, is inserted into the receptacle 8a of the shift lever 6, the detent springs 15 are initially compressed together. As the element is inserted further, the detent lugs 16 are engaged by the pre-tensioned detent springs 12 with the assistance of a spreading locking bar 7g, 7'g located in the receptacle 8a (see Fig. 12 ), corresponding to the spreader bar 7f, pressed outwards again into the guide recesses 17.

[0070] In the second coupling position B ( Fig. 11a ) the locking lugs 16 then come into positive contact with the upper retaining sections 17a of the guide recess 17, with at the same time the lug 12a of the switching pin 12 resting on the surface 7e of the switching lever 6.

[0071] In this way, the coupling element 11 is fixed in the second coupling position B with respect to its longitudinal movement, as the locking lugs 16, in conjunction with the upper retaining sections 17a of the guide recess 17, prevent the coupling element 11 from being pulled out (with a specific force below the breaking point), and the lug 12a also provides a specific holding force against the coupling element 11 being pushed in. In this way, the locking lugs 16 additionally provide a captive function for the coupling element 11.

[0072] The holding force of the locking lugs 16 can be increased by the spreading section 7f described above (see Fig. 10b ) are reinforced. This increases the unlosability function.

[0073] To assume the first coupling position A, the holding force of the nose 12a must be overcome. Then, the switching pin 12 of the coupling element 11 can be pushed further into the receptacle 8a until the nose 12a engages with the lateral retaining sections 17b of the guide receptacles 17, thus fixing and maintaining the first coupling position A of the coupling element A. This is described in Fig. 11b depicted.

[0074] Fig. 12-13 schematic perspective partial views in top view of the actuating sections 8, 8'; 8a, 8' of the disconnect terminals according to the first example after Fig. 2 .

[0075] In transition areas between the consecutive receptacles 8 and 8a, as well as 8' and 8'a, two opposing guide grooves 8b, 8'b are formed into the sides of the receptacles 8' and 8'a. These guide grooves 8b, 8'b extend over the entire length of each respective receptacle 8', 8'a.

[0076] The guide grooves 8b correspond to the guide ribs 12b of the switching pin 12 and engage with them when the coupling element 11 is inserted into the receptacle. Similarly, the guide grooves 8'b correspond to the guide ribs 13a of the driver 13 and engage with them as well. The guide grooves 8b, 8'b and guide ribs 12b, 13a also ensure that the coupling element 11 is inserted into the receptacles 8a, 8'a without error. This is due to Fig. 13 evident.

[0077] Fig. 14-16 show schematic representations of a variant of the coupling element 11 according to Fig. 10-10b in different coupling positions.

[0078] Fig. 14 shows how Fig. 11 the coupling element 11 before insertion. In Fig. 15 is similar to in Fig. 11a The second coupling position B is shown. Fig. 16 presents how the Fig. 11b This represents the first coupling position A.

[0079] In this variant, the guide ribs 12b extend only over half the length of the switching pin 12. The detent lugs 16 are laterally formed on the free ends of the detent springs 12. The retaining sections 17a and 17b of the guide recesses 17 merge into one another.

[0080] In the second coupling position B, which Fig. 15 As shown, the locking lug 16 is in positive contact with the upper retaining section 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 can easily be imagined.

[0081] Fig. 15a Figure 1 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 linearly guided in the guide grooves 8b. The expanding locking web 7g is engaged, demonstrating that in coupling position B the detent springs 15, also referred to as spring arms, cannot disengage.

[0082] In the first coupling position A, the nose 12a is not only engaged with the lateral retaining section 17b of the guide recess 17, but the nose 12a is also in contact with the upper retaining section 17a of the guide recess.

[0083] In the examples shown, the switching, adjusting, or movement direction of the coupling element 11 is linear in the radial direction with respect to the pivot axis 5a. However, the switching / adjusting / movement direction can also be rotational or follow a different path. This would, however, be in a different direction than the direction in which the actuating movement of the shift lever 6, 6' about the pivot axis 5a takes place; for example, a different path is also conceivable.

[0084] In the preceding examples, the coupling element 11 is shown inserted into the switching lever 6 of the front disconnect terminal 1 with the switching pin 12. Of course, the coupling element 11 can also be inserted rotated by 180°, with the switching pin 12 inserted into the receptacle 8'a of the rear disconnect terminal 1' and the driver 13 into the receptacle 8a of the front disconnect terminal 1. In this way, the switching levers 6 and 6' can be selectively connected to each other.

[0085] Not shown, but conceivable, is 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, for example, three or four or more disconnect terminals 1, 1' can be additionally connected.

[0086] These additional connections can be made all or only partially in the first coupling position A. Intermediate positions are possible between the first coupling position A and the second coupling position B, in which the switching levers 6, 6' of the further disconnect terminals 1, 1' are connected.

[0087] An unillustrated but conceivable variant of the coupling element 11 consists of the coupling element 11 having two pins of equal length that are inserted into the receptacles of the adjacent shift levers 6, 6', and the handle 14 having a separation (e.g., in the middle) that is closed when the shift levers 6, 6' are connected, i.e., in the first coupling position A. The separation is opened to disengage the connected shift levers 6, 6' and obtain the second coupling position B. This opening is achieved by pivoting the separable parts of the handle 14, together with their associated pins, apart in opposite directions about the axes of the respective pins in the receptacles of the shift levers 6, 6'. The pins remain in the receptacles of the shift levers during this pivoting. The separation is positive-locking, e.g., like two gears or gear segments that are disengaged.

[0088] In yet another variant of the coupling element 11, the switching pin 12 is rotatably mounted on the handle 14. This version is not shown, but can be seen in connection with the figures (e.g. Fig. 6 , 11This is easily conceivable. When the coupling element 11 is in the second coupling position B, the handle 14, together with the driver 13, can be rotated 180° about the longitudinal axis of the switch pin 12 remaining in the associated receptacle 8a due to the rotatably mounted switching pin 12. This is advantageous if the arrangement 10 has, for example, three disconnect terminals 1, 1', where the disconnect terminal 1 is connected to 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 disconnect terminal 1' can be selectively connected in the first coupling position A, without having to completely remove the coupling element 11 with the switching pin 12 from the associated receptacle 8a and turn it around.

[0089] In Fig. 17 is a schematic perspective view of a second example of the disconnect terminal 1, 1' according to Fig. 2 shown with a coupling device 100.

[0090] The coupling device 100 here has a coupling element 18 that can be pivoted about an axis 19. The pivotable coupling element 18 is also referred to as a switchable rotational locking element.

[0091] Furthermore, it is conceivable, but not elaborated upon, that there may be other switching positions / mechanisms that, for example, can cause a coupling of a central disconnect terminal 1, 1' to disconnect terminals 1, 1' arranged to the left or right of it.

[0092] In the actuating sections 7, 7' of the shift levers 6, 6', only the receptacles 8, 8' for an actuating tool are formed. 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', an actuating section 7, 7' projects radially.

[0093] The coupling element 18 is pivotable about the axis 19 on the radially projecting actuating section 7 of the shift lever 6 and is captive held on it. The axis 19 runs perpendicular to the pivot axis 5a of the shift lever 6, 6', and is tangential to an imaginary circle with a center point through which the pivot axis 5a of the shift lever 6, 6' lies.

[0094] The coupling element 18 can move from a first coupling position A to a second coupling position B (see Fig. 19, 19a ) can be switched by means of pivoting around axis 19. This will be explained in detail below.

[0095] Fig. 18-21 schematic perspective partial views of the coupling device 100 of the second example are shown. Fig. 17 in various coupling positions and switching states.

[0096] Fig. 18 indicates switch position I and in Fig. 18a The switching position II is shown. The coupling element 18 is in coupling position A, in which it couples the two shift levers 6, 6' or locks them together.

[0097] The coupling element 18 is a type of elongated hood and comprises a pivot section 18a, a shaft section 18b with 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 along 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 another transverse wall 18e.

[0098] The pivot section 18a is formed from the first, rounded ends of the side walls 18d, between which the shaft section 18b is attached.

[0099] The shaft section 18b has a disk-shaped solid shaft section 18i and a section that flattens towards the axis 19. This flattened section is referred to as the key surface 18j. The key surface 18j runs parallel to the lower edges of the side walls 18d and points downwards when the coupling element 18 is in the first coupling position A.

[0100] The coupling section 18c is defined by the second ends of the side walls 18d and the transverse wall 18f.

[0101] The distance between the parallel side walls 18d corresponds to a thickness of the actuating sections 7, 7' projecting radially from the shift levers 6, 6' such that the free end areas of the actuating sections 7, 7' can each be accommodated between the side walls 18d of the coupling element 18.

[0102] The pivot section 18a and the coupling section 18c thus form two interconnected hood sections.

[0103] The shaft section 18b of the pivoting section 18a of the coupling element 18 is pivotably mounted in a receptacle 20 of the projecting actuating section 7. This will be explained in detail below. An inner diameter of the receptacle 20, 20' corresponds to an outer diameter of the disk-shaped solid shaft section 18i of the shaft section 18. In this way, the coupling element 18 is pivotably mounted on the projecting actuating section 7.

[0104] In the first coupling position A, which is in Fig. 17 , 18 und 18a As shown, the coupling element 18 is pivoted over the radially projecting actuating section 7' ​​of the adjacent shift lever 6' and positively coupled to it. The coupling section 18c surrounds the radially projecting 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 18 runs parallel to the pivot axis 5a of the shift levers 6, 6'. Simultaneously, in coupling position A, the coupling section 18c is fixed to the radially projecting actuating section 7' ​​by a detent device, which will be described below.

[0105] Lever projections 18g are formed on the upper end regions of the side walls 18d of the coupling section 18c. Using these lever projections 18g as handles, the coupling element 18 can be manually pivoted from the first coupling position A to 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. The pivot angle between the two coupling positions A and B is 90°.

[0106] In the second coupling position B, the coupling element 18, or rather its longitudinal axis, is perpendicular to the actuating section 7 of the shift lever 6 and radially oriented with respect to the pivot axis 5a. The coupling element 18 is held in this second coupling position B by a detent device or detent mechanism, which will be explained in more detail below.

[0107] In Fig. 19 The switch position I is shown and in Fig. 19a The 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 to each other.

[0108] Fig. 19 The figure also shows the actuating 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 identically to 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 identical. No special versions are required.

[0109] The actuation section 7, 7' of the shift lever 6, 6' of the second example according to Fig. 17 is in Fig. 22-22a depicted in schematic perspective views. Fig. 22b shows a side view of actuation section 7.

[0110] Fig. 23-27 show schematic representations of the coupling element 18 as well as at least partial representations of the actuating section 7, 7' of the second example according to Fig. 17 .

[0111] The actuating section 7, 7' is provided with a receptacle 20, 20' at its upper end. The receptacle 20, 20' is cylindrical, has an axis 19a, 19'a and extends perpendicularly to the pivot axis 5a of the shift levers 6, 6'. The axis 19a, 19'a forms a tangent to an imaginary circle through whose center the pivot axis 5a passes.

[0112] The inner wall of the opening 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 approximately one quarter of the length of the opening 21, 21' and has a recess 20a, 20'a with an opening width corresponding 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 opening 20, 20' and has a projecting longitudinal rim LR. The opening width of this second area with the longitudinal rim LR is smaller than the diameter of the opening 20, 20'. The longitudinal rim LR of the opening 21, 21' has an undercut 20b, 20'b.

[0113] During assembly, the coupling element 18 is inserted into the receptacle 20 of the actuating section 7 of the shift lever 6, together with the shaft section 18b of the pivot section 18a, through the opening 21. This is only possible in a specific assembly position C, which is shown in Fig. 20-21 As shown, the coupling element 18 is positioned at an angle of approximately 30° to the pivot axis 5a. The mounting position is therefore approximately 150° different from the first coupling position A with respect to the axis 19. When the coupling element 18 is in mounting position C, the key surface 18j points upwards. In this position, the flattened key surface 18j of the shaft section 18b facilitates insertion into the receptacle 20 of the actuating section 7. This flattened key surface 18j reduces the outer dimension of the shaft section 18b, allowing it to be easily inserted into the receptacle 20, 20' due to the smaller opening width. The disc-shaped solid shaft section 18i fits with its diameter through the first area of ​​the opening 21, 21' into the recess 20a, 20'a provided for this purpose.

[0114] When the coupling element 18 is inserted into the receptacle 20, 20' in the mounting position C in this manner, which Fig. 21 As shown, 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 the mounting position C, the coupling element 18 is held captive via the shaft section 18b in the receptacle 20 by the undercut 20b.

[0115] 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 each other.

[0116] The coupling element 18 has two detent positions. The first detent position is formed in the first coupling position A, parallel to the pivot axis 5a of the shift levers 6, 6', by a detent device or detent mechanism. This detent 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 several are provided.

[0117] The second detent position of the coupling element 18 is the second coupling position B perpendicular to the pivot axis 5a of the shift lever 6, wherein a detent device or detent mechanism with a protruding section and a corresponding molded section is provided. In the example shown here in part, this detent device comprises a molded recess 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 inner side of the side wall 18d of the coupling element 18 in the area of ​​the pivot section 18a. The web 18k is molded 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 shown in Fig. 18 und 18a It is clearly visible where the web 18k is positioned perpendicular to the pivot axis 5a and also perpendicular to the molded-indentation 7h in the first coupling position A. In the second coupling position B, the web 18k engages with the molded-indentation 7h. This is shown in Fig. 25 to be recognized. The bridge 18k runs parallel to the pivot axis 5a and parallel to the molding 7h.

[0118] In another example, this locking device for the second coupling position B can have a 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 is / are engaged in the second coupling position B with an end of the opening 21, 21' and / or an end of the receptacle 20, 20' between the longitudinal edge LR and a lower longitudinal edge.

[0119] If another adjacent gearshift lever (e.g. in Fig. 21 Because the coupling element 18 is located in front of the front gearshift lever 6), it cannot be pivoted into mounting position C and cannot be removed. This is in Fig. 28 depicted.

[0120] In this example, the direction of movement of the coupling element 18 is rotational around the axis 19. However, the movement can also be rotationally supplemented 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.

[0121] Fig. 23 Figure 18 is a side view of the coupling element 18 in the mounting position C in relation to the actuating section 7 of the shift lever 6 shown next to it. The axis 19 runs here outside an imaginary longitudinal axis of the coupling element 18.

[0122] In Fig. 24 Figure 1 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, e.g., from a suitable plastic material. The key surface 18j is located between the left side wall 18d and the disk-shaped solid shaft section 18i. A reduction in the outer dimension of the shaft section 18b compared to the solid shaft section 18i is clearly visible.

[0123] Fig. 25 Figure 1 shows a side view of actuating section 7 of the shift lever 6 and of 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 the coupling element 18, the spherical segment-shaped projections 18h of the detent device protrude into the interior of the coupling section 18c.

[0124] In Fig. 26 The coupling element 18 of the locking device is located in the first coupling position A. A sectional view along line XXVII through the coupling section 18c is shown in Fig. 27 shown, wherein the projections 18h engage with the open ends of the receptacle 20' of the actuating section 7' ​​of the adjacent shift lever 6' and form a detent position.

[0125] In Fig. 27 An additional detent device for the first coupling position A is indicated, which (like the detent device for the second coupling position B described above) has a protruding section as a web 18'k and a molded-in section as a recess 7'h of the actuating section 7' ​​of the shift lever 6'. 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 recess 7'h and engages with the recess 7'h.

[0126] The webs 18k, 18'k and the associated recesses 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, angular, oval, cross-shaped, etc. Naturally, these locking devices for the coupling positions A, B can also be extended to include further coupling positions of the coupling element 18.

[0127] With this principle of the coupling element 18 of the second example, the independent switching of adjacent shift levers 6, 6' is possible from any position.

[0128] Fig. 28-29 schematic partial representations of coupling devices 100 of disconnect terminals 1, 1' according to the second example after Fig. 17 .

[0129] Fig. 28 Figure 1 shows two pairs of shift levers 6, 6'; 6, 6', where the two front shift levers 6, 6' are shown with the coupling element 18 of the coupling device 100 in coupling position A. The coupling element 18 of the other coupling device 100 is in the second coupling position B.

[0130] The coupling element 18 can also be configured for more than two shift levers 6, 6'. This shows Fig. 29 An example of four shift levers 6, 6'. The coupling element 18 is correspondingly longer. The areas of the coupling element 18 that couple the actuating sections 7' of the middle shift levers 6' can also be provided with corresponding projections 18h.

[0131] Fig. 30-33a represent schematic views of a coupling device 100 of a third example of disconnect terminals 1, 1'.

[0132] 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'.

[0133] Recording 23, 23' corresponds to page 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 separated by a partition 27, 27' from a further receptacle 24, 24', which in turn is also opened to the other side section 7c, 7'c of the actuating section 7, 7' via a slot 25a, 25'a.

[0134] The coupling element 22, 22' is in Fig. 33-33a The diagram is shown in perspective from various views and in its installed state. 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 radially attached 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, e.g., 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 segment. Diametrically opposite the formed hook section 22b, 22'b, a lug 22e, 22'e (a cam) is attached to the outside of the body 22a, 22'a. This nose 22a, 22'a extends from the front 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.

[0135] The receptacle 23, 23' corresponds to the shape of the coupling element 22, 22' and is closed in its lower section with a curved receptacle wall 27a, 27'a with an undercut 23a, 23'a in the area of ​​the slot 25, 25', the radius of which corresponds to the radius of the body 22a, 22'a of the coupling element 22, 22'.

[0136] 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 to engage with the hook section 22b, 22'b of the coupling element 22, 22' in the slot 25a, 25'a.

[0137] 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' openings 26, 26' for access to the slots 22d, 22'd of the coupling element 22, 22' for pivoting the same are formed in the end face section 7b, 7'b, and wherein 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 provided. In this way, the coupling element 22, 22' is guided through the bearing sections 29, 29' and the lower receiving wall 27a, 27'a and the intermediate wall 27, 27' and can be pivoted about the pivot axis 22c, 22'c in the receiving 23, 23'.

[0138] The pivot axis 22c, 22'c is perpendicular 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' passes.

[0139] The coupling element 22, 22' is clipped into the receptacle 23, 23' from the side section 7d, 7'd through the slot 25, 25', the undercut 23a, 23'a and the spherical bearing projection 22f, 22'f holding the coupling element 22, 22' captive in the receptacle 23, 23'.

[0140] Fig. 30 Figure 1 shows two coupling elements 22, 22' in adjacent actuating sections 7, 7' of adjacent shift levers 6, 6' in the first coupling position A. The hook sections 22b, 22'b are located within the receptacles 23, 23'.

[0141] Fig. 30b Figure 1 shows the receptacles 23, 23'; 24, 24' closed by the side sections 7b, 7'b with the openings 26, 26' through which the coupling elements 22, 22' can be pivoted about their pivot axes 22c, 22'c from the first coupling position A to the second coupling position B and back using a tool, preferably a screwdriver, in engagement with the actuating sections 22d, 22'd.

[0142] The openings 26, 26' are provided here with additional stops 26a, 26'a for the tool in order to restrict a pivoting of the coupling element 22, 22' to the coupling positions A and B.

[0143] In Fig. 30a and 30cThe 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 engage with the receptacle 24 of the adjacent actuating section 7, 7', thereby enabling coupling of the adjacent shift levers 6, 6'.

[0144] It is also conceivable that two opposing hook sections 22b, e.g. in the form of an anchor, are provided, wherein the coupling element 22, 22' can be pivoted in two different pivot directions, taking up a middle position in the second coupling position B.

[0145] In Fig. 31 Only one coupling element 22' is pivoted into the second coupling position B, while the other coupling element 22 remains in the first coupling position A. The coupling elements 22 and 22' can therefore be switched, adjusted, and pivoted independently of each other.

[0146] 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 into the first coupling position A, i.e., it does not perform any locking action with the adjacent shift lever(s) 6, 6'.

[0147] The underside of the recording wall 27a, 27'a is in Fig. 31a each shown with a cutout 28, 28'.

[0148] Fig. 31b shows the coupling elements 22, 22' from Fig. 31 und 31a without page breaks. In Fig. 31c Only the open recordings 23, 23'; 24, 24' without coupling elements 22, 22' are shown.

[0149] The partition wall 27, 27' also has a recess 28a, 28'a.

[0150] The recesses 28, 28'; 28a, 28'a correspond in their form to the nose 22e, 22'e of the coupling element 22, 22'.

[0151] As from Fig. 31a and 31bAs can be clearly seen, the nose 22e of the coupling element 22 located in the first coupling position A engages with the recess 28 in the lower receiving wall 27a and thus forms a locking of the coupling element 22 in the first coupling position A.

[0152] The nose 22'e of the other coupling element 22', which is in the second coupling position B, engages with the other recess 28'a in the partition wall 27. This enables the coupling element 22' to be locked in the second coupling position B.

[0153] Exclusions 28, 28' and 28a, 28'a are in Fig. 32 shown enlarged together with storage sections 29, 29'

[0154] The areas of the actuation sections 7, 7' of the shift levers 6, 6' with the molded-in receptacles 23, 23'; 24, 24' are shown here as box-shaped. These box-shaped areas are integrally formed with the shift levers 6, 6'.

[0155] In another embodiment, these box-shaped areas or receiving sections can also be designed as separate parts, which are suitably attached to the shift levers 6, 6'. Such attachment can be, for example, a clip connection, a tongue-and-groove connection, a screw connection, a plug connection, or the like.

[0156] In Fig. 34-40c Schematic views of switching status indicators 30 are shown.

[0157] The respective switching position I, II, i.e. the connecting position and the disconnecting position of the shift levers 6, 6', is visibly indicated by the switching status indicator 30.

[0158] This is implemented such that, on the one hand, a first display section 31 is arranged on the movable switching lever 6, 6' or the actuating section 7, 7', and, on the other hand, a second display section 32, corresponding to 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 a "closed" symbol is clearly visible. And in the second switching position II ("separated"), this symbol is separated, from which a separation is clearly recognizable.

[0159] The following geometric solutions are possible: Geometric fraction (e.g., two separate / merged semicircles - closed circle, fork and connection point). Arrow-shaped geometric elements that are not visible in switch position I. Switch symbols: fork with connection point or open / closed switch symbol. Surfaces flush in switch position I. Elements can be colored to indicate grouping, provide contrast, or serve as a traffic light.

[0160] Several examples of this can be found in Fig. 34-40c shown.

[0161] Fig. 34-34a show switch position II, whereby Fig. 34b-34c to indicate switching position I. According to the invention, the movable display section 31 is a fork-shaped circular arc that encloses the stationary display section 32, which is designed as a protruding circular cylinder, in switching position II.

[0162] Show the geometric inversion Fig. 35-35a in switch position II and Fig. 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 the stationary display section 32.

[0163] According to the invention, show Fig. 36-36c two separate semicircles, which are then joined together as a closed circle in switching position I.

[0164] Fig. 37-37c is a variant of the embodiment according to the invention Fig. 35-35c , wherein the stationary display section 32 has an upwardly projecting symbolism that represents the switching state I as a plug-in connector symbol.

[0165] Fig. 38-38c and Fig. 39-39c Each shows a cut-through contour that can be recognized as joined together in switching state I.
