Description

TECHNICAL FIELD

[0001] The present invention relates to a disconnect terminal with a switching state display.

[0002] Disconnect terminals of this type are used in different applications. BACKGROUND

[0003] DE 44 45 551 A1 describes a current transformer disconnect terminal with a switching element in the form of an angularly adjustable contact disc, which ensures that the secondary side of a connected current transformer is never disconnected when the current path is opened or closed by the terminal, by means of a contact drag wire. The contact disc can be adjusted in angle by means of a pivoting lever about a rotation axis. The operation of the current transformer disconnect terminal, i.e. in the case of a plurality of directly adjacent disconnect terminals, the pivoting lever can be pivoted manually from one switching position to another switching position, since a connecting pin is inserted into the handle of the pivoting lever of the directly adjacent disconnect terminal.

[0004] DE 44 45 556 A1 relates to a switchable terminal box with a switching lever handle made of insulating material. The handle is provided with two visible surfaces, in each of the two switching positions of the switching lever, one visible surface faces the viewing direction of the operator, and the other visible surface faces away from the viewing direction of the operator in the same switching position. The handles of directly adjacent terminal boxes can be connected by means of a transparent cap which overlaps two or more handles.

[0005] DE 10 2008 014 176 B4 describes a terminal box and a series disconnect switch with a knife switch, for a pivotably arranged in a terminal housing of the terminal box, with one terminal housing, in which a busbar consisting of two parts and two conductor connection elements is arranged for connecting a conductor to each part of the busbar, wherein the two parts are connected to each other in a first position of the knife switch and are separated from each other in a second position of the knife switch. The knife switch is partially surrounded by an insulating housing. Not only can the series disconnect switch be operated by means of a screwdriver, for which purpose the screwdriver is inserted into an operating shaft of the insulating housing, but also by means of a switching connection which comprises two legs and a handle part of a connecting leg. Thus, two series disconnect switches of two terminal connections arranged next to each other can be simultaneously manipulated, for which purpose one foot is inserted into the operating shaft of each series disconnect switch.

[0006] The known disconnect terminals have proven themselves.

[0007] However, there is a need to perfect these disconnect terminals in order to achieve a simple, quick recognizability of the switching positions. SUMMARY

[0008] The object of the present application is to solve this problem. The present application achieves these objects by the subject matter of claim 1.

[0009] A circuit-breaking terminal according to the present application comprises at least one switching lever, wherein the switching lever can be adjusted independently of a further switching lever from a first switching position at least to a second switching position and back. The circuit-breaking terminal comprises a switching state display with a movable display part and a fixed display part, wherein the switching state display visually displays the respective switching position or at least one further switching position, wherein in the first switching position the two display parts are unified so that a "closed" symbol is clearly visible, and wherein in the second switching position the symbol is separated, from which the separation is clearly visible from the symbol.

[0010] An advantageous simple and unambiguous switching state display is thereby achieved.

[0011] It is noted here that such a switching state display can also be used for other terminal types, for example those with coupling elements.

[0012] A further embodiment provides that at least the first switching position is displayed by covering the display part and / or making the display part visible, and at least the second switching position is displayed by making the display part visible and / or covering the display part. This achieves a compact construction.

[0013] In a further embodiment, the switching state display is advantageously assisted in recognition by coloring, symbols and / or geometric shapes.

[0014] This is advantageous because recognition is also possible from greater distances.

[0015] Further advantageous designs can be derived from the remaining dependent claims. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] The terms "top", "bottom", "left", "right" refer to the respective arrangement of components in the drawing.

[0019] Figure 1 schematic perspective view of a conventional circuit-breaking terminal 1 in a device 10, which here comprises two circuit-breaking terminals 1, 1' (of course, there can also be more than two circuit-breaking terminals 1, 1'). ​​​​​​​​

[0020] In order to distinguish between the two disconnection terminals 1, 1', in the following the reference signs of the disconnection terminal 1' arranged behind in the figures are identified by an apostrophe, including the reference signs of the individual parts / sections thereof. In the description the different functions of the front and rear disconnection terminals 1, 1' are shown separately.

[0021] Such disconnection terminals 1, 1' are also referred to as scalable disconnection terminals 1, 1', measurement disconnection terminals or series disconnection terminals.

[0022] The disconnection terminals 1, 1' comprise a housing 2, 2' having a first terminal section 3, 3', a second terminal section 4, 4' and a separating section 5, 5' arranged in between.

[0023] In the first connection section 3, 3' a first clamping section (not described in detail) for connecting a conductor wire (not shown) is arranged.

[0024] The first clamping section is connected to a first conductor track 3a which extends through a connecting section (not determined) into the separating section 5.

[0025] In a similar manner, in the second terminal section 4, 4' a second clamping section (not described in detail) for connecting another conductor wire (not shown) is arranged in a mirror image to the first terminal section 3, 3'. The second clamping section is connected to a second conductor track 4a which extends through a connecting section (not shown) into the separating section 5, 5'.

[0026] The connecting sections of the conductor tracks 3a and 4a are operatively connected to a switching device (not shown) in the separating section 5, 5'. The switching device comprises a switching lever 6, 6' which is adjustable from a first switching position I to a second switching position II and back. Here, the switching lever 6, 6' is pivoted about a pivot axis 5a in a switching movement SB.

[0027] The pivot axis 5a here extends perpendicular to a side face (not shown) of the housing 2, 2' of the disconnection terminal 1, 1'.

[0028] In the first switching position I, which here is also referred to as the coupling position, the switching device electrically connects the two connecting sections and the first conductor track 3a and the second conductor track 4a, so that the first clamping section is connected to the second clamping section in an electrically conductive manner. The upper region of the switching lever 6 here adjoins a stop section 9 of the housing 2 which has an actuation section 7, as Figure 1 in the case of the front disconnection terminal 1 in.

[0029] In the second switching position II, which is also referred to herein as the disengaged position, the two connection portions are separated and isolated from one another, i.e. the electrically conductive connection of the two connection portions and of the conductor tracks 3a and 4a is eliminated or separated, wherein the conductor track 3’a is still electrically connected to the switching lever 6’ here.

[0030] In this second switching position II, the actuating portion 7’ of the switching lever 6’ abuts a further stop portion 9’a of the housing 2, as is shown in the rear off-circuit terminal 1’. Figure 1 In addition, in the switching position II, a contact bridge (not shown in detail) is contacted in such a way that, in the case of the switching position II, all of the terminals 3, 3’ of the off-circuit terminals positioned adjacent to one another are electrically conductively connected to one another / short-circuited by means of the contact bridge. The contact bridge is provided with contacts facing the switching lever similar to the conductor tracks 3a, 4a.

[0031] In the example shown in Figure 1 the accommodation 8, 8’ is recessed into the actuating portion 7, 7’ in the radial direction from above with respect to the pivot axis 5a.

[0032] The switching lever 6, 6’ is actuated here manually and / or using a suitable tool, for example a screwdriver which engages in the accommodation 8, 8’.

[0033] The actuating portion 7, 7’ of the switching lever 6, 6’ comprises two opposite face portions each. Firstly, there is an end face portion 7a, 7’a which faces the terminal portion 4, 4’ of the switching position I. Opposite this, an end face portion 7b, 7’b faces the terminal portion 3, 3’ of the switching position II. A face portion 7c, 7’c is perpendicular to the surface which extends perpendicular to the pivot axis 5a. And opposite this, a face portion 7d, 7’d.

[0034] Figure 2 A schematic perspective view of a first exemplary embodiment of an off-circuit terminal 1, 1’ according to the application is shown, which has a coupling device 100 according to the application; the device 10 comprises two adjacent off-circuit terminals 1, 1’.

[0035] The coupling device 100 is used to couple at least two adjacent switching levers 6, 6’ in the two adjacent off-circuit terminals 1, 1’.

[0036] The term “coupling” is to be understood as meaning that the at least two adjacent switching levers 6, 6’ are locked and / or connected to one another, such that they can be switched together from the switching position I to the switching position II and back again. When the “coupling” is eliminated, the switching levers 6, 6’ are separated from one another again and can be actuated independently of one another.

[0037] In the example shown in Figure 1In the conventional circuit-breaking terminal 1, 1' shown, a bracket plug with two plug pins is inserted into the receiving portion 8, 8' of the switching lever 6, 6' of the circuit-breaking terminal 1, 1'. The two switching levers 6, 6' can be connected and adjusted by means of the bracket plug. Only with the bracket plug removed again is it possible to adjust the switching levers 6, 6' independently of one another.

[0038] In contrast thereto, the coupling device 100 according to exemplary embodiments of the application comprises a switchable or adjustable coupling element 11, as shown, which couples the two switching levers 6, 6' to one another, but can also embody more than two switching levers 6, 6', as will be readily apparent. Figure 2

[0039] The term "switchable" is to be understood as meaning that the respective coupling element 11, 18, 22 of the coupling device 100 is adjusted from a first position to a second position and back again. The adjustment can take place rotationally and / or linearly.

[0040] In addition, it is conceivable, but not explained in more detail, that there can be further switching positions / mechanisms, which can for example enable the coupling of an intermediate circuit-breaking terminal to a circuit-breaking terminal arranged adjacent to the left or right thereof. This is not shown, but is readily conceivable.

[0041] In the actuation portion 7, 7' of the switching lever 6, 6', two adjacent receiving portions 8, 8a and 8', 8'a are formed in the circumferential direction with respect to the pivot axis 5a, respectively. The receiving portions 8a, 8'a serve for receiving the coupling element 11 and are arranged between the receiving portions 8, 8' and the end face portion 7a, 7'a of the actuation portion 7, 7'.

[0042] The end face portion 7a, 7'a is in contact with a stop 9, 9' of the housing 2, 2', respectively, in the switching position I. In the switching position II, a further end face portion 7b, 7'b of the actuation portion 7, 7' of the shaft lever 6, 6' is in contact with a further stop 9a, 9'a of the housing 2, 2', respectively.

[0043] The coupling element 11 is inserted into one of the switching levers 6, 6' and is held captive in this position by engagement behind it. In addition, the coupling element 11 is movably guided in this switching lever 6, 6' and can be switched from a first coupling position A to a second coupling position B (see Figure 4 , 6 , 7). This will be explained in more detail hereinafter.

[0044] Figures 3-9 Schematic partial perspective views of the coupling device 100 according to the application in various coupling positions A, B and switching positions I, II are shown. Figure 2 ​​

[0045] exist Figure 3 The image shows the coupling element 11 before it is inserted into the receiving portions 8, 8' of the switching levers 6, 6' in the so-called pre-installation position. In the switching position I, the switching levers 6, 6' are both adjacent to the stops 9, 9' of the corresponding housings 2, 2'.

[0046] The coupling element 11 includes a switching pin 12, an actuator 13, and a handle 14. The switching pin 12 and the actuator 13 are attached to the lower side 4a of the handle 14. Here, the length of the switching pin 12 is more than twice the length of the actuator 13. The switching pin 12 and the actuator 13 are arranged adjacent to each other relative to the pivot axis 5a.

[0047] Figure 4 The circuit-breaking terminals 1 and 1' with switching levers 6 and 6' and coupling device 100 are shown in switching position I, wherein switching position II is as follows: Figure 5 As shown.

[0048] Here, the coupling element 11 is linearly inserted radially into the receiving portions 8a, 8'a of the actuating portions 7, 7' of the switching levers 6, 6' in the radial direction. Therefore, the long switching pin 12 is accommodated within... Figures 2 to 9 The switching lever 6 of the front circuit breaker terminal 1 is housed in the receiving portion 8a. The short-circuit driver 13 is housed in... Figures 2 to 9 The switch lever 6' shown is housed in or engaged with the receiving portion 8'a of the rear disconnect terminal 1'. In this case, the lower side 4a of the handle 14 of the coupling element 11 is placed on the surfaces 7e, 7'e of the actuating portions 7, 7'. This position of the coupling element 11 corresponds to the first coupling position A ( Figure 4 In the first coupling position A, the coupling (also known as the lock) of the switching levers 6 and 6' is (mechanically) engaged.

[0049] In this way, the switching levers 6 and 6' are coupled by the coupling element 11 in the first coupling position A, so that the two switching levers 6 and 6' use the handle 14 of the coupling element 11 to perform a switching motion SB from switching position I to switching position II. Figure 2 The adjustment can be performed manually and then reversed. Alternatively, it can be adjusted using a tool, preferably a screwdriver, which is inserted into one of the receiving portions 8 or 8' of the actuating portions 7 or 7' of the switching levers 6 or 6'.

[0050] Figure 6 The second coupling position B of the coupling element 11 of the coupling device 100 in the first switching position I is shown.

[0051] In the second coupling position B, the coupling element 11 is radially adjusted in the receiving portion 8a of the actuation portion 7 of the front switching lever 6 by the switching stroke SH, outside the first coupling position A. The second coupling position B is thus activated.

[0052] In the second coupling position B, the driver 13 of the coupling element 11 is completely moved out of the accommodation 8'a of the actuation portion 7' of the rear switching lever 6', so that the coupling between the shaft levers 6, 6' is eliminated. In other words, the driver 13 is disengaged from the accommodation 8'a in the second coupling position B.

[0053] In this way, the coupling element 11 can be linearly switched or adjusted in the radial direction with respect to the pivot axis 5a.

[0054] Thus, for example, the rear switching lever 6 can be adjusted by means of a tool W, preferably a screwdriver, which is inserted into the accommodation 8' independently of the front switching lever 6 Figure 7 the switching position II shown.

[0055] Likewise, the front switching lever 6 can be adjusted from Figure 8 the switching position I shown to Figure 9 the switching position II shown, independently of the rear switching lever 6'.

[0056] In each case, the coupling element 11 is fixed in the first coupling position A by means of the switching pin 12 in the associated accommodation 8 and in the second coupling position B by means of the stop mechanism in the respective accommodation 8. In the following Figures 10 to 13 is described in more detail.

[0057] Figures 10-10b A schematic perspective view of a coupling element 11 of a coupling device 100 according to a first exemplary embodiment of a circuit-breaking terminal 1, 1' according to the application is shown in accordance with Figure 2 .

[0058] The switching pin 12 of the coupling element 11 comprises a lug 12a and at least one stop spring 15 with a stop spring 16 as a stop mechanism. The lug 12a is arranged on the switching pin 12 in a strip-shaped form 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 faces the associated stop portion 9d and here extends parallel to the edge of the underside 14a of the handle 14 and parallel to the pivot axis 5a in the installed state of the coupling element 11.

[0059] Here, two opposing stop springs 15 are provided approximately at the lower third of the switching pin 12, an outwardly protruding stop lug 16 being formed in the lower region on the outer side of each stop spring. The stop lugs 16 protrude in the width direction of the handle 14. Therein, in the installed state of the coupling element 11, the width direction extends in the direction of the pivot axis 5a.

[0060] Each stop spring 15 tapers towards its respective free end in the direction of the longitudinal axis of the switching pin 12, so that a wedge-shaped intermediate space 15b is formed between the inner surfaces 15a of the stop springs 15. A U-shaped recess (not shown) which extends essentially parallel to the direction of extension (see Figure 15a ) is located behind it.

[0061] The expansion 7f can be accommodated in this wedge-shaped intermediate space 15b and / or in this U-shaped recess. The expansion 7f can be arranged in the accommodation 8a and interact with the inner surfaces 15a and / or with the U-shaped recess, so that if the switching pin 12 is inserted into the accommodation 8a during the insertion of the coupling element 11, it pushes the stop spring 15 with the stop lug 16 outwards. The advantage of this is that the holding effect of the stop lug 16 is strengthened. This will also be explained in connection with Figure 11a and 11b .

[0062] Furthermore, starting from the lower side 14a of the handle 14, a guide web 12b which extends over the entire length of the connecting pin 12 and a corresponding positioning spring 15 are formed on the switching pin 12. In the example shown, two opposite guide webs 12b are provided.

[0063] The driver 13 also comprises two opposite guide webs 13a which extend over the entire length of the driver 13 on two opposite longitudinal sides of the driver 13.

[0064] The handle 14 here comprises an arrow as a symbol 14b which points downwards to the switching lever 6, 6' and thus indicates the insertion direction of the coupling element 11 in the direction towards the first coupling position A.

[0065] With this principle, it is possible to switch adjacent switching levers 6, 6' independently from almost any position. The only exception is that both switching levers 6, 6' are in the second switching position II, while the coupling element 11 is in the coupling position B. Then, it is not possible to move Figures 2-9 the switching lever 6' located behind in

[0066] Figures 11-11b Schematic perspective views of a coupling device 100 of a first exemplary embodiment of a circuit-breaking terminal 1, 1' according to the application according to Figure 2 are shown in various coupling positions.

[0067] In the respective actuation portion 7, 7', a guide recess 17 is recessed in the opposite side wall 6a of the switching lever 6 (and in the opposite side wall 6a of the switching lever 6', which is not shown but is readily conceivable). The guide recess 17 is an elliptical hole and forms a lateral opening of the receiving portion 8a, 8'a with an upper retaining portion 17a and a lateral retaining portion 17b. Here, the upper retaining portion 17a is formed by the upper rounding of the guide recess 17. The lateral retaining portion 17b is introduced approximately in a half circle laterally, which is approximately at the upper quarter of the guide recess 17.

[0068] When the coupling element 11 with the switching pin 12 is inserted with its stop spring 15 in front into the receiving portion 8a of the switching lever 6, the stop spring 15 is first compressed towards each other. After further insertion, the stop lug 16 is pressed again outwards into the guide recess 17 by the expanded locking web 7g, 7'g with the help of the pre-tensioned stop spring 12 (see Figure 12 ), corresponding to the expanded web 7f in the receiving portion 8a.

[0069] Then, in the second coupling position B (see Figure 11a ), the stop lug 16 is in form-fitting contact with the upper retaining portion 17a of the guide recess 17, wherein the lug 12a of the switching pin 12 is at the same time on the surface 7e of the switching lever 6.

[0070] In this way, the coupling element 11 is fixed in its longitudinal movement selection in the second coupling position B, wherein the stop lug 16 together with the upper retaining portion 17a of the guide recess 17 prevents the coupling element 11 from retracting (with a defined force lying below the breaking limit), the lug 12a also pushes the coupling element 11 in with a defined retaining force. In this way, the stop lug 16 additionally forms a capture function of the coupling element 11.

[0071] The retaining force of the stop lug 16 can be strengthened by the above-mentioned expansion 7f (see Figure 10b ). The capture function is thus enhanced.

[0072] In order to reach the first coupling position A, the retaining force of the lug 12a must be overcome. The switching pin 12 of the coupling element 11 can then be pushed further into the receiving portion 8a until the lug 12a engages with the lateral retaining portion 17b of the guide recess 17 and in this way fixes and holds the first coupling position A of the coupling element A. This is shown in Figure 11b .

[0073] Figures 12-13 Schematic partial perspective view of the actuation portion 8, 8' of a circuit-breaking terminal according to the first exemplary embodiment of Figure 2 .

[0074] In the transition area between the successive housings 8 and 8a and 8' and 8'a, two opposite guide grooves 8b, 8'b are respectively shaped as the side faces of the housings 8' and 8'a. These guide grooves 8b, 8'b respectively extend over the entire length of the corresponding housings 8', 8'a.

[0075] The guide groove 8b corresponds to the guide web 12b of the switching pin 12 and engages with the guide web 12b when the coupling element 11 is inserted and inserted into the housing. In the same way, the guide groove 8'b corresponds to the guide webs 13a of the driver 13 and also engages with them. Furthermore, the guide grooves 8b, 8'b and the guide webs 12b, 13a form the way in which the coupling element 11 is inserted into the housings 8a, 8'a without fusion. From Figure 13 It can be clearly seen Figures 14 to 16 A schematic representation of a variant of the coupling element 11 according to the application is shown in different coupling positions. Figures 10 to 10b

[0076] Analogous to Figure 11 , Figure 14 The coupling element 11 is shown before insertion. The second coupling position B is shown in Figure 15 analogous to Figure 11a . Figure 16 A first coupling position A is shown analogous to Figure 11b .

[0077] In this variant, the guide web 12b extends only over half the length of the switching pin 12. The stop lug 16 is formed laterally on the free end of the stop spring 12. The holding portions 17a and 17b of the guide recess 17 merge into one another.

[0078] In the second coupling position B shown, the stop lug 16 is in positive contact with the upper holding portion 17a of the guide recess 17. The same is true on the other side of the switching lever 6, not shown, but easily conceivable. Figure 15

[0079] Figure 15a A sectional view through the actuating portion 7 of the switching lever 6 in the second coupling position B of the coupling element 11 is shown. The guide web 12b is linearly accommodated in the guide groove 8b. The extended locking web 7g is engaged and shows that in the coupling position B the stop spring 15, also called spring leg, cannot be deflected.

[0080] In the first coupling position A, the lug 12a not only engages with the lateral holding portion 17b of the guide recess 17, but the lug 12a also comes into contact with the upper holding portion 17a of the guide recess.

[0081] ​​In the example shown, the switching or adjustment or movement direction of the coupling element 11 is linear in the radial direction relative to the pivot axis 5a. However, the switching / adjustment / movement direction can also extend rotationally or along another trajectory. However, this can occur in a direction which differs from the direction in which the actuation movement of the switching lever 6, 6' extends about the pivot axis 5a, for example along another trajectory.

[0082] In the preceding example, the coupling element 11 is shown which has a switching pin 12 which is inserted into the switching lever 6 of the front circuit-breaking terminal 1. Of course, the coupling element 11 can also be inserted by 180° rotation, wherein the switching pin 12 is inserted into the receptacle 8'a of the rear circuit-breaking terminal 1', and the driver 13 is inserted into the receptacle 8a of the front circuit-breaking terminal 1. In this way, the switching levers 6, 6' can be connected to one another alternately.

[0083] Not shown, but conceivable, is a coupling element 11 which comprises one switching pin 12 and two or more drivers 13. These drivers 13 can be arranged on one side, right or left of the switching pin 12, or on both sides, uniformly or non-uniformly distributed. In this way, the switching levers 6, 6' can additionally be connected by, for example, three or four or more circuit-breaking terminals 1, 1'.

[0084] All these additional connections or only some of them can be established 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 additional circuit-breaking terminals 1, 1' are connected therein.

[0085] Not shown, but conceivable, is a variant of the coupling element 11 which comprises two pins of equal length which are inserted into the receptacles of adjacent switching levers 6, 6', and the handle 14 has, for example, a gap in the middle which is closed in the connected state of the switching levers 6, 6', i.e. in the first coupling position A. This gap is opened to eliminate the connected state of the switching levers 6, 6' to obtain the second coupling position B. The opening occurs because the separable parts of the handle 14 are pivoted away from one another in opposite pivot directions about the axis of the respective pin in the respective receptacle of the switching lever 6, 6' together with the associated pin. In this case, the pegs remain in the receptacles of the switching levers. The separation is form-fitting, for example as two disengaged gears or tooth segments.

[0086] In a further variant of the coupling element 11, the switching pin 12 is attached to the handle 14 rotationally. This embodiment is not shown, but is described in conjunction with the figures, for example, Figure 6 , 11It is easily conceivable that, if the coupling element 11 is in the second coupling position B, in this variant, due to the rotatable attachment of the switching pin 12 about the longitudinal axis of the switching pin 12 which is held in the associated receptacle 8a, the handle 14 can be pivoted 180° together with the driver 13. This is advantageous if the device 10 comprises, for example, three circuit-breaking terminals 1, 1’, wherein the circuit-breaking terminal 1 has a receptacle 8a into which the coupling element 11 with the switching pin 12 is inserted. In this way, by pivoting the handle 14 together with the driver 13 into the second coupling position B, alternatively one switching lever 6’ of the adjacent circuit-breaking terminal 1’ can be connected in the first coupling position A, without the switching pin 12 of the coupling element 11 having to be completely pulled out of the associated receptacle 8a and turned over.

[0087] Figure 17 A schematic perspective view of a second exemplary embodiment of a circuit-breaking terminal 1, 1’ according to the application with a coupling device 100 according to the application is shown. Figure 2

[0088] The coupling device 100 here comprises a pivotable coupling element 18 which can be pivoted about an axis of rotation 19. The pivotable coupling element 18 is also referred to as a switchable rotary locking element.

[0089] Furthermore, it is conceivable, but not explained in detail, that there can be further switching positions / mechanisms, for example, which can enable the coupling of an intermediate circuit-breaking terminal 1, 1’ with circuit-breaking terminals 1, 1’ arranged to the left or right thereof.

[0090] Here, the receptacles 8, 8’ for the manipulation tools are each recessed in the actuation portion 7, 7’ of the switching lever 6, 6’. One actuation portion 7, 7’ projects radially between the receptacle 8, 8’ and the other end face portion 7b, 7’b of the actuation portion 7, 7’ of the switching lever 6, 6’.

[0091] The coupling element 18 can be pivoted about the axis of rotation 19 on the radially projecting actuation portion 7 of the switching lever 6 and is held captive thereon. The axis of rotation 19 extends perpendicular to the pivot axis 5a of the switching lever 6, 6’, wherein the axis of rotation 19 is tangential to an imaginary circle having a centre point through which the pivot axis 5a of the switching lever 6, 6’ extends.

[0092] The coupling element 18 can be switched from the first coupling position A to the second coupling position B (see Figure 19 , 19a ) by pivoting about the axis of rotation 19. This will be explained in more detail in the following.

[0093] Figures 18-21 A schematic perspective view of a second exemplary embodiment of a circuit-breaking terminal 1, 1’ according to the application with a coupling device 100 according to the application is shown. Figure 17 ​Fig. 2 shows a schematic perspective view of the coupling device 100 of the second exemplary embodiment.

[0094] Figure 18 Fig. 1 shows a switching position I, Figure 18a Fig. 2 shows a switching position II. The coupling elements 18 are in the coupling position A, respectively, in which the coupling elements 18 couple and / or lock the two switching levers 6, 6' to each other.

[0095] The coupling element 18 is an oval-shaped housing and comprises a pivot portion 18a, a shaft portion 18b with an axis 19 and a coupling portion 18c. The pivot portion 18a and the coupling portion 18c are connected by two side walls 18d which are arranged in parallel. The side walls 18d are connected in the middle of their upper longitudinal side by a transverse wall 18e. In the end region of the coupling portion 18c, the ends of the side walls 18d are connected by a further transverse wall 18e.

[0096] The pivot portion 18a is formed by the first, circular ends of the side walls 18d between which the shaft portion 18b is attached.

[0097] The shaft portion 18b comprises a disc-shaped solid shaft portion 18i and a portion which is flattened in the direction of the axis 19. This flattened portion is referred to as a key surface 18j. Here, the key surface 18j extends parallel to the lower edge of the side walls 18d and faces downwards when the coupling element 18 is in the first coupling position A.

[0098] The coupling portion 18c is determined by the second ends of the side walls 18d and the transverse wall 18f.

[0099] The distance between the parallel side walls 18d corresponds to the thickness of the actuation portions 7, 7' which protrude radially from the switching levers 6, 6', so that the free end regions of the actuation portions 7, 7' can be accommodated between the side walls 18d of the coupling element 18, respectively.

[0100] The pivot portion 18a and the coupling portion 18c thus form two housing portions which are connected to each other.

[0101] The shaft portion 18b of the pivot portion 18a of the coupling element 18 is accommodated pivotably in the accommodation 20 of the protruding actuation portion 7. This will be explained in more detail below. The inner diameter of the accommodation 20, 20' corresponds to the outer diameter of the disc-shaped solid shaft portion 18i of the shaft portion 18. In this way, the coupling element 18 is pivotably attached to the protruding actuation portion 7.

[0102] In Figure 17 , 18In the first coupling position A shown in Fig. 18a, the coupling element 18 is pivoted and coupled in a form-fitting manner to the radially protruding actuation portion 7' of the adjacent switching lever 6'. The coupling portion 18c here surrounds the radially protruding actuation portion 7' of the adjacent switching lever 6' like a hood. The longitudinal axis of the coupling element 18 extends in the first coupling position A parallel to the pivot axis 5a of the switching lever 6, 6'. At the same time, the coupling portion 18c is fixed on the radially protruding actuation portion 7' in the engagement position A by means of a detent device, which will be described below.

[0103] On each upper end region of the side wall 18d of the connecting portion 18c, a lever extension 18g is formed. By means of the overhanging lever extension 18g as a handle portion, the coupling element 18 can be manually pivoted from the first coupling position A to the second coupling position B by lifting the coupling portion 18c and pivoting the coupling element 18 about the shaft portion 18b and its axis 19. Here, the pivoting angle between the two coupling positions A and B is 90°.

[0104] In the second coupling position B, the coupling element 18 or its longitudinal axis is perpendicular to the actuation portion 7 of the switching lever 6 and radial with respect to the pivot axis 5a. The coupling element 18 is held in this second coupling position B by means of a detent device or detent mechanism, which will be described in more detail below.

[0105] Figure 19 The switching position I is shown, and the switching position II is shown in Figure 19a The coupling element 18 is in the coupling position B in each case, in which the two switching levers 6, 6' are neither coupled nor locked.

[0106] Figure 19 The actuation portion 7' of the switching lever 6' is also shown, which is free in the second coupling position B of the coupling element 18. This actuation portion 7' is formed here exactly like the other actuation portion 7 of the other switching lever 6. In other words, the switching levers 6, 6' and the actuation portions 7, 7' are identical. No special embodiment is required.

[0107] In Figures 22-22a the actuation portions 7, 7' of the switching levers 6, 6' according to the second exemplary embodiment of the Figure 17 is shown in a schematic perspective view. Figure 22b A side view of the actuation portion 7 is shown.

[0108] Figures 23-27 A schematic view of the coupling element 18 according to the second exemplary embodiment of the Figure 17 is shown together with at least a partial schematic view of the actuation portions 7, 7'.

[0109] The actuating portion 7, 7' is provided in its upper end region with a receptacle 20, 20'. The receptacle 20, 20' is cylindrical, comprises an axis of rotation 19a, 19'a and extends perpendicular to the pivot axis 5a of the switching lever 6, 6'. The axis of rotation 19a, 19'a extends through the centre of an imaginary circle, the tangent of which is the pivot axis 5a.

[0110] The inner wall of the receptacle 20, 20' is interrupted by an opening 21, 21' which extends parallel to the direction of the axis of rotation 19a, 19'a. The opening 21, 21' has two regions with different opening widths. A first region (arranged to the left of Figure 22 the opening 21, 21') corresponds to approximately one quarter of the length of the opening 21, 21' and has a recess 20a, 20'a which has an opening width corresponding to the diameter of the receptacle 20, 20'. A second region (in the vicinity of the first region to the right of Figure 22 the opening 21, 21') extends over approximately three quarters of the total length of the receptacle 20, 20' and comprises a protruding longitudinal edge LR. The opening width of this second region with the longitudinal edge LR is smaller than the diameter of the receptacle 20, 20'. The longitudinal edge LR of the opening 21, 21' comprises here an undercut 20b, 20'b.

[0111] The coupling element 18 is inserted into the receptacle 20 of the actuating portion 7 of the switching lever 6 by means of the shaft portion 18b of the pivot portion 18a through the opening 21 when assembled. This is only possible in a specific mounting position C as shown in Figures 20-21 In this case, the coupling element 18 is angled at approximately 30° with respect to the pivot axis 5a. The mounting position is thus positioned at approximately 150° with respect to the axis 19 with respect to the first coupling position A. If the coupling element 18 is in the mounting position C, the key surface 18j faces upwards. In this position, the key surface 18j of the shaft portion 18b is flattened, facilitating the insertion of the shaft portion 18b into the receptacle 20 of the actuating portion 7, since the flattened key surface 18j reduces the outer dimensions of the shaft portion 18b in such a way that, due to the smaller opening width, the shaft portion 18b can be easily inserted into the receptacle 20, 20'. The diameter of the disc-shaped solid shaft portion 18i is fitted through the first region of the opening 21, 21' into the recess 20a, 20'a provided for this purpose.

[0112] If the coupling element 18 is inserted in this way into the receptacle 20, 20' in the mounting position C, as shown in Figure 21 , the coupling element 18 is pivoted into the second coupling position B. In this second coupling position B, the coupling element 18 is held captive in the receptacle 20 via the shaft portion 18b via the undercut 20b, as in the first coupling position A and in all other positions except the mounting position C.

[0113] In the mounted state of the coupling element 18, the axis 19 of the shaft portion 18a of the coupling element 18 and the axis 19a of the receptacle 20 extend coaxially to one another.

[0114] The coupling element 18 has two stop positions. A first stop position is formed in the first coupling position A parallel to the pivot axis 5a of the switching lever 6, 6' by a stop device or stop mechanism. This stop device comprises at least one protrusion 18h in the form of a spherical section. In the example shown, in the region of the coupling portion 18c of the coupling element 18, a protrusion 18h in the form of a spherical section is present on the inner side of each side wall 18d and engages with the end of the receptacle 20' of the actuation portion 7' of the adjacent switching lever 6'. It is also possible to provide only one protrusion 18h in the form of a spherical section or several protrusions 18h.

[0115] The second stop position of the coupling element 18 is the second coupling position B perpendicular to the pivot axis 5a of the switching lever 6. There is provided a stop device or stop mechanism there, which has a protruding portion and a corresponding recessed portion. In the example shown in part, this stop device comprises recesses 7h, 7'h in the form of elongate grooves, which recesses are present as recessed portions on one side of the actuation portion 7, 7'. On the inner side of the side wall 18d of the coupling element 18 in the region of the pivot portion 18a, there is a web 18k as a protruding portion. The web 18k is formed in the end region of the side wall 18d of the coupling element 18 in the pivot portion 18a perpendicular to the longitudinal edge of the side wall 18d. This is evident in Figure 18 and 18a , in which, in the first coupling position A, the web 18k is perpendicular to the pivot axis 5a and also to the recess 7h. In the second coupling position B, the web 18k engages with the recess 7h. This is evident in Figure 25 . The web 18k here extends parallel to the pivot axis 5a and parallel to the recess 7h.

[0116] In another example, this stop device for the second coupling position B can comprise a protrusion (or two or more, similar to the protrusion 18h), which is not shown but is readily conceivable on the inner side of the side wall 18d in the pivot portion 18a of the coupling element 18, which engages with one end of the opening 21, 21' and / or one end of the receptacle 20, 20' between the longitudinal edge LR and the lower longitudinal edge in the second coupling position B.

[0117] If another switching lever (for example, the front switching lever 6 in front of the Figure 21 , is arranged adjacent, the coupling element 18 cannot be pivoted into the mounted position C nor can it be removed. As Figure 28 is shown.

[0118] In this embodiment, the movement direction of the coupling element 18 extends rotationally about the axis 19. However, this movement can also be designed rotationally by another trajectory, but in a plane different from the actuation plane of the switching lever 6. A movement along another trajectory can also be considered.

[0119] Figure 23 is a side view of the coupling element 18 in the installed position C relative to the actuation portion 7 of the adjacent shown switching lever 6. Here, the axis 19 extends outside the imaginary longitudinal axis of the coupling element 18.

[0120] In Figure 24 is shown in a cross section through the coupling element 18 in the region of the pivot portion 18a through the shaft portion 18b. The shaft portion 18b, the disc-shaped solid shaft portion 18i and the side wall 18d are here made integrally, for example, from a suitable plastic material. The key surface 18j is arranged here between the left-hand side wall 18d and the disc-shaped solid shaft portion 18i. The reduction in the outer dimensions of the shaft portion 18b relative to the solid shaft portion 18i is apparent.

[0121] Figure 25 is shown in a side view of the actuation portion 7 of the switching lever 6 and the coupling element 18 in the second coupling position B. The protrusion 18h of the spherical cross section of the stop device protrudes from the inside of the side wall 18d into the interior of the coupling portion 18c in the region of the coupling portion 18b of the coupling element 18.

[0122] In Figure 26 is shown in a side view of the coupling element 18 of the stop device in the first coupling position A. In Figure 27 is shown in a cross section along the line XXVII to the coupling portion 18c, in which the protrusion 18h engages with the open end of the receptacle 20' of the actuation portion 7' of the adjacent switching lever 6' and forms a stop position.

[0123] In Figure 27 is shown an additional stop device for the first coupling position A (similar to the stop device of the second coupling position B described above), comprising a protruding part as a web 18'k and a recessed part as a recess 7'h of the actuation portion 7' of the switching lever 6'. The web 18'k is arranged in the coupling portion 18c of the coupling element 18 parallel to its longitudinal edges on its side wall 18d. In the first coupling position A, the web 18'k extends parallel to the pivot axis 5a and parallel to the recess 7'h and engages with the recess 7'h.

[0124] For both coupling positions A, B, the webs 18k, 18'k and the associated recesses 7h, 7'h can of course also be arranged at other angles with respect to the pivot axis 5a. They can also have other shapes, for example a spherical cross-section, a polygon, an oval, a cross, etc. Of course, these stop means for the coupling positions A, B can also be extended for further coupling positions of the coupling element 18.

[0125] Using the principle of the coupling element 18 of the second exemplary embodiment, the adjacent switching levers 6, 6' can be switched independently from any position.

[0126] Figures 28-29 A schematic partial view of a coupling device 100 of a circuit-breaking terminal 1, 1' is shown according to a second exemplary embodiment of the coupling element 18. Figure 17

[0127] Figure 28 Two pairs of switching levers 6, 6'; 6, 6' are shown, wherein two front switching levers 6, 6' are shown, which have a coupling element 18 of a coupling device 100 in the coupling position A. A coupling element 18 of the other coupling device 100 is in the second coupling position B.

[0128] The coupling element 18 can also be designed for more than two switching levers 6, 6'. Figure 29 Here, an example of four switching levers 6, 6' is shown. The coupling element 18 is correspondingly longer in construction. The region of the coupling element 18, in which the actuation portion 7' of the middle switching lever 6' is coupled, can also be provided with a corresponding protrusion 18h.

[0129] Figures 30-33a A schematic view of a coupling device 100 of a third exemplary embodiment of a circuit-breaking terminal 1, 1' is shown.

[0130] The coupling device 100 comprises rotatable or pivotable coupling elements 22, 22', which are arranged in a receiving portion 23, 23' in the actuation portion 7, 7' of the switching lever 6, 6'.

[0131] The receiving portion 23, 23' opens via a slot 25, 25' towards a side portion 7d, 7'd of the actuation portion 7, 7' (see Figure 1 ). Towards the other side portion 7c, 7'c, the receiving portion 23, 23' opens through an intermediate wall 27, 27' of a further receiving portion 24, 24', which in turn opens via a slot 25a, 25'a towards the other side portion 7c, 7'c of the actuation portion 7, 7'.

[0132] The coupling elements 22, 22' are shown in perspective from various angles and mounted in Figures 33-33a ​The coupling element comprises a cylindrical body 22a, 22'a with a pivot axis 22c, 22'c. An arm with a hook-shaped portion 22b, 22'b is attached radially to the body 22a, 22'a. The body 22a, 22'a comprises on one end face an actuating portion 22d, 22'd, which here is in the form of a slot, for a suitable tool, for example a screwdriver. The other end face of the body 22a, 22'a is provided with a bearing protrusion 22f, 22'f formed centrally, here in the form of a spherical cross-section. A lug 22e, 22'e (cam) is attached diametrically to the formed hook-shaped portion 22b, 22'b on the outside of the body 22a, 22'a. The lug 22a, 22'a extends from the end face of the body 22a, 22'a. The bearing portion 22f, 22'f extends to approximately half the length of the body 22a, 22'a parallel to the pivot axis 22c, 22'c.

[0133] The accommodation 23, 23' corresponds to the shape of the coupling element 22, 22' and is closed in its lower part with a curved accommodation wall 27a, 27'a, which in the region of the slot 25, 25' has an undercut 23a, 23'a, the radius of which corresponds to the radius of the body 22a, 22'a of the coupling element 22, 22'.

[0134] The accommodation 24, 24' corresponds to the hook-shaped portion 22b, 22'b of the coupling element 22, 22' and has in its lower region an undercut 24a, 24'a, which is arranged to engage with the hook-shaped portion 22b, 22'b of the coupling element 22, 22' in the slot 25a, 25'a.

[0135] The accommodations 23, 23' and 24, 24' are closed by the end face portions 7a, 7'a and 7b, 7'b of the actuating portion 7, 7', wherein the openings 26, 26' for access to the slot 22d, 22'd of the coupling element 22, 22' to pivot it are recessed in the end face portion 7b, 7'b in the region of the body 22a, 22'a of the coupling element 22, 22', wherein the bearing portion 29, 29' is introduced into the opposite end face portion 7a, 7'a for mounting the bearing protrusion 22f, 22'f of the coupling element 22, 22'. In this way, the coupling element 22, 22' is pivotably guided by the bearing portion 29, 29' and the lower accommodation wall 27a, 27'a and the intermediate wall 27, 27' around the pivot axis 22c, 22'c in the accommodation 23, 23'.

[0136] The pivot axis 22c, 22'c is perpendicular to the pivot axis 5a of the switching lever 6, 6' and tangential to an imaginary circle with a centre point, through which the pivot axis 5a of the switching lever 6, 6' extends.

[0137] The coupling elements 22, 22' are clamped into the receptacles 23, 23' from the side portions 7d, 7'd through the slots 25, 25', wherein the undercuts 23a, 23'a and the bearing protrusions 22f, 22'f in the form of a spherical cross section captively hold the coupling elements 22, 22' in the receptacles 23, 23'.

[0138] Figure 30 Two coupling elements 22, 22' in adjacent actuating portions 7, 7' of adjacent switching levers 6, 6' in the first coupling position A are shown. The hook-shaped portions 22b, 22'b are inside the receptacles 23, 23'.

[0139] Figure 30b The receptacles 23, 23', 24, 24' are shown closed by the side portions 7b, 7'b, which have openings 26, 26' through which, using a tool, preferably a screwdriver, they can be brought into engagement with the actuating portions 22d, 22'd, around which the coupling elements 22, 22' can be pivoted from the first coupling position A into the second coupling position B and back.

[0140] The openings 26, 26' are here provided with additional stops 26a, 26'a for the tool in order to limit the pivoting of the coupling elements 22, 22' to the coupling positions A and B.

[0141] In Figure 30a and 30c the second coupling position B is shown. The pivoting coupling elements 22, 22' are such that the hook-shaped portions 22b, 22'b extend through the slots 25, 25' and engage the receptacles 24 of the adjacent actuating portions 7, 7', thus enabling the coupling of the adjacent switching levers 6, 6'.

[0142] It is also conceivable to provide two opposing hook-shaped portions 22b, for example in the form of an anchor, wherein the coupling element 22, 22' can be pivoted in two different pivoting directions, wherein it is in an intermediate position in the second coupling position B.

[0143] In Figure 31 only one coupling element 22' is pivoted into the second coupling position B, the other coupling element 22 remains in the first coupling position A. The coupling elements 22, 22' are thus independently switchable and / or adjustable and / or pivotable from one another.

[0144] Thus, once the coupling elements 22, 22' on the respective adjacent switching levers 6, 6' are switched into the first coupling position A, independent movement of the switching levers 6, 6' can be achieved and thus no locking with the adjacent switching levers 6, 6'.

[0145] In Figure 31aIn the figures, the lower side of the accommodation walls 27a, 27'a is shown, which has the recesses 28, 28'.

[0146] Figure 31b The coupling elements 22, 22' of Figure 31 and 31a are shown without a lateral section. In Figure 31c only the open accommodation 23, 23', 24, 24' is shown without the coupling elements 22, 22'.

[0147] The intermediate walls 27, 27' also comprise recesses 28a, 28'a.

[0148] The shape of the recesses 28, 28', 28a, 28'a corresponds to the lugs 22e, 22'e of the coupling elements 22, 22'.

[0149] From Figure 31a and 31b it is apparent that the lug 22e of the coupling element 22 in the first coupling position A engages with the recess 28 in the lower accommodation wall 27a, thereby locking the coupling element 22 in the first coupling position A.

[0150] The lug 22'e of the other coupling element 22' in the second coupling position B engages with the other recess 28'a in the intermediate wall 27. Thus, the coupling element 22' can be locked in the second coupling position B.

[0151] The recesses 28, 28' and 28a, 28'a together with the bearing portions 29, 29' are shown enlarged in Figure 32 .

[0152] Here, the regions of the actuation portions 7, 7' of the toggle levers 6, 6' with the recessed accommodations 23, 23', 24, 24' are shown. These box-shaped regions are formed integrally with the toggle levers 6, 6'.

[0153] In another embodiment, these box-shaped regions or accommodations can also be formed as separate components, which are attached to the toggle levers 6, 6' in a suitable manner. Such attachments can be formed, for example, as a clip connection, a tongue-and-groove connection, a screw connection, a plug connection, etc.

[0154] Figures 34-40c A schematic view of the switching status display 30 is shown.

[0155] The individual switching positions I, II, i.e. the coupling positions and the decoupling positions of the toggle levers 6, 6', are visually displayed by the switching status display 30.

[0156] This is achieved by arranging the first display part 31 on the movable switching lever 6, 6' or actuation part 7, 7' on the one hand and the second display part 32, which is matched thereto, is attached to the fixed housing on the other hand. In the first switching position I ("closed"), the two display parts 31 and 32 are unified in such a way that the "closed" symbol is clearly visible. And in the second switching position II ("separated"), the symbol is separated, which is clearly visible from the separation of the symbol.

[0157] For this purpose, the following geometric solutions can be employed: - geometric break (e.g. two half circles separate / merge - closed circle) - fork and connection point - geometric element designed in the form of an arrow, not visible in switching position I.

[0158] - switching symbol: fork with open / close connection point or switching symbol - surfaces flush in switching position I - the elements can be colored to indicate unity, provide contrast or communication light function.

[0159] Figures 34-40c Different examples of such embodiments are shown.

[0160] Figures 34-34a Switching position II is shown, in which Figures 34b-34c Switching position I is shown. In this case, the movable display part 31 is a fork-shaped circular arc, which in switching position I surrounds the fixed display part 32, which is formed as a protruding cylinder.

[0161] The geometric inversion is shown in Figures 35-35a switching position II and Figures 35b-35c switching position I. Now, the cylinder is the movable display part 31, which in switching position I is surrounded by its corresponding housing as the fixed display part 32.

[0162] Figures 36-36c The separation of the two half circles is shown, which are then merged into one closed circle in switching position I.

[0163] Figures 37-37c is a variant according to Figures 35-35c the embodiment, in which the fixed display part 32 comprises a symbol protruding upwards, which represents the switching state I as a plug-in connection circuit symbol plugged together.

[0164] Figures 38-38c and Figures 39-39cThe cut-in profile is shown separately and can be identified as being engaged in switching state I.

[0165] Figures 40-40a The color circuit symbol of the break switch as a movable display part 31 is shown. The fixed display part 32 is an opening in the form of a circuit symbol for a make switch. In switching position I, the circuit symbol of the break switch is no longer visible, wherein the opening in the form of a circuit symbol for a make switch is represented by the colored background of the movable display part 31 located below.

[0166] The switching state display can also be designed to have a certain traffic signal function.
