Description
[0001] The present invention relates to a disconnect terminal according to the preamble of claim 1. The invention also relates to an arrangement of at least two disconnect terminals.
[0002] Such isolating terminals are used in a variety of applications. For example, document DE 197 48 640 C1 describes a measuring isolating terminal arrangement for the operation of current transformers, in which busbar sections are equipped with conductor connections and contacts. For connecting current measuring devices or external voltages, for example, an isolating contact is necessary. This is achieved by an isolating contact piece that interacts with the contacts.
[0003] DE 44 44 551 A1 describes a current transformer isolating terminal with a contact piece in the form of an angle-adjustable contact disc, which, by means of a contact trailing path, ensures that the secondary side of a connected current transformer can never be open when the current passage through the terminal is interrupted or closed.
[0004] Document DE 101 18 919 A1 describes an auxiliary switch that can be mounted on an installation switch. The movable contact pieces are mounted in a contact carrier that is coupled to one arm of a rotatably mounted first double-arm lever, while the other arm is coupled to a movable element of the installation device. The auxiliary switch has a test assembly that is coupled to the contact carrier via a freewheel such that, upon actuation of the test assembly, the contact carrier is displaced without moving the first double-arm lever.
[0005] DE29723167U1 discloses the features of the preamble of independent claim 1.
[0006] The existing isolating terminals have proven themselves to be effective. However, it is desirable to further develop these isolating terminals, allowing for simple, quick, and clear identification of the respective switching position of an isolating terminal—i.e., a connected position and a disconnected position. At the same time, a compact design and a low number of components are achieved.
[0007] Solving this problem is the object of the invention. The invention solves this problem through the subject matter of claim 1 and through the subject matter of claim 15.
[0008] A disconnect terminal according to the invention comprises a housing, a first conductor rail and a second conductor rail, a switching device, and an actuating device, wherein the switching device can be adjusted by means of the actuating device from a connected position, in which the first conductor rail and the second conductor rail are electrically connected by the switching device, into a disconnected position, in which the electrically conductive connection between the first conductor rail and the second conductor rail is severed, and back again. In the connected position, a visible portion of the actuating device is aligned with a surface of a portion of an upper side of the housing or of a part connected to the housing, and in the disconnected position, the visible portion of the actuating device protrudes clearly visible from a surface of a portion of an upper side of the housing or of a part connected to the housing.
[0009] This enables the switching state of the isolating terminal to be identified quickly and clearly.
[0010] The section of the housing is, for example, a top surface of a wall of the housing, a surface on the top side of a component of the housing or an inserted part of the housing, e.g. a bridge holder.
[0011] An arrangement according to the invention has at least two of the isolating terminals described above.
[0012] In a particularly preferred embodiment, the switching device comprises a contact plate made of an electrically conductive contact material with contact sections, one contact section forming a trailing contact. The contact plate can advantageously be manufactured simply, e.g., as a stamped part.
[0013] In the connected position, the contact plate connects the conductor rails electrically via the contact sections in a particularly simple manner. The contact plate is, for example, a type of blade contact that interacts with the contact forks of the conductor rails.
[0014] It is advantageous if, in the disconnected position, the contact plate electrically connects the first conductor rail via the contact section forming the trailing contact and the contact section with a bridge contact. This allows for a simple connection of the respective first conductor rails in the disconnected position when connecting disconnect terminals in series, which is advantageous, for example, for use as current transformer disconnect terminals.
[0015] In one embodiment, the switching device and the actuating device have a common sliding element, which is designed to be linearly movable and is connected to the contact plate. This results in an advantageously compact design with a low number of components.
[0016] It is also advantageous that the sliding element has an actuating section with the viewing section, since the viewing section does not form an additional component.
[0017] In a further embodiment, the linearly movable sliding element is coupled to a limiting slide via a gear mechanism, whereby the limiting slide determines the travel of the linearly movable sliding element in cooperation with stops of a guide section in a body of the housing. One advantage is that the travel of the sliding element can be easily limited.
[0018] In an alternative embodiment, the switching device comprises a linearly movable sliding element with the contact plate, wherein the actuating device comprises a separate actuating element coupled to the sliding element via a toothing or other positive drive mechanism. Another positive drive mechanism could be, for example, a rack and pinion coupling. This provides the advantage of simple manual actuation with minimal effort.
[0019] The actuating element of the actuating device has an actuating section with a viewing section, and the actuating element is arranged so that it can pivot about an axis. This advantageously allows for a compact design.
[0020] In another embodiment, the sliding element can have a web-shaped guide section with a front surface containing the viewing section. This can advantageously provide an additional indication of the current switching position of the disconnect terminal.
[0021] In a further alternative embodiment, the switching device comprises a linearly movable sliding element with the contact plate, wherein the actuating device comprises a separate actuating lever, which has the visible section and is coupled to the sliding element via a lever mechanism. The lever mechanism enables advantageous power transmission from a manual actuation to the sliding element. Furthermore, defined end positions can be easily achieved.
[0022] In a further embodiment, the lever mechanism comprises an actuating lever and a transmission lever, with the transmission lever being coupled to the sliding element. This results in a simple design with minimal space requirements.
[0023] In yet another alternative embodiment, the switching device comprises a switching lever with an actuating end having the visible portion, and the switching device is formed by the contact plate, wherein the contact plate has an elongated, knife-like shape. This advantageously results in a simple and space-saving design.
[0024] Another design provides for the switching lever of the actuating device to be firmly connected to the elongated, blade-like contact plate of the switching device and to be pivotable with the contact plate about a common, stationary switching lever axis. This design is advantageous because only a few components are required. Furthermore, only minimal manual force is required. Of course, a suitable tool or actuating device can also be used.
[0025] In a further embodiment, the switching lever rests with its actuating end against a housing stop in the connected position, with the visible portion being aligned with a surface of the housing stop. In the disconnected position, the switching lever with the contact plate is pivoted about the fixed pivot axis and rests against a bridge holder as a stop, with the visible portion of the actuating end of the switching lever protruding from the surface of the bridge holder as a section or component of the housing. In this way, a clear and simple detection of the switching state or switching position of the disconnect terminal can be achieved.
[0026] In one embodiment of the arrangement, the at least two isolating terminals jointly comprise a bridge holder with bridge contacts that are electrically connected to one another. This advantageously expands the application range of the isolating terminals.
[0027] A further embodiment of the arrangement provides that the respective sliding elements and / or limit slides and / or actuating elements of the at least two isolating terminals are connected to one another by detachable actuating elements to enable synchronous actuation. This advantageously allows for simple and rapid actuation.
[0028] Further advantageous embodiments can be found in the remaining subclaims.

[0030] The terms "top", "bottom", "left", "right" refer to the respective arrangement of the components in the figures.
[0031] Fig. 1 shows a schematic perspective view of an embodiment of a disconnect terminal 1 according to the invention with a block diagram of a switching device 9 and an actuating device 10.
[0032] The isolating terminal 1 comprises a housing 2 with a first connection section 2a, a second connection section 2b and a isolating section 2c arranged centrally therebetween.
[0033] A first terminal section 3 (not described in detail) for connecting an electrically conductive line (not shown) is arranged in the first connection section 2a. The first terminal section 3 is connected to a first conductor rail 4, which extends into the separating section 2c with a connecting section 5.
[0034] Similarly, a second clamping section 6 (not described in detail) for connecting another electrically conductive line (not shown) is arranged in the second connection section 2b, mirror-inverted to the first connection section 2a. The second clamping section 6 is connected to a second conductor rail 7, which extends into the separating section 2c with a connecting section 8.
[0035] The connecting section 5 of the first conductor rail 4 and the connecting section 8 of the second conductor rail 8 are operatively connected to a switching device 9. The switching device 9 has two positions. In a connecting position, the switching device 9 electrically connects the two connecting sections 5 and 8, and thus the first conductor rail 4 and the second conductor rail 8, so that the first clamping section 3 is electrically connected to the second clamping section 6.
[0036] In a disconnected position of the switching device 9, the two connecting sections 5 and 8 are separated and insulated from each other, ie the electrically conductive connection of the two connecting sections 5 and 8 and thus of the conductor rails 4 and 8 is canceled or separated.
[0037] The switching device 9 is coupled to an actuating device 10. The actuating device 10 is designed to adjust the switching device 9 from the connected position to the disconnected position and back. The actuating device 10 is actuated manually and / or with a suitable tool. The respective position, i.e. the connected position and the disconnected position of the switching device 9, is visibly indicated by the actuating device 10. This is designed such that a visible portion 102 of the actuating device 9, in the connected position, is aligned with a surface 12, 12a of a portion of an upper side of the housing 2 or with a part connected to the housing 2, and that the visible portion 102 of the actuating device 9, in the disconnected position, protrudes clearly from the surface 12, 12a of a portion of the upper side of the housing 2 or of a part connected to the housing 2.
[0038] The switching device 9 and the actuating device 10 coupled thereto are arranged in the separating section 2c as a separating unit 11, which in Fig. 1 marked by dashed double-dotted lines.
[0039] In the Fig. 1 In the example shown, two isolating terminals 1 are arranged side by side (of course, there can also be more than two isolating terminals 1). For certain applications of these isolating terminals 1, it is necessary, for example, that the first terminal sections 3 are short-circuited in the disconnected position of the isolating terminals 1, i.e., that they are electrically connected to one another. For this purpose, the switching device 9 can connect the first terminal sections 3 to one another in the disconnected position by means of a so-called short-circuit bridge. This will be described in more detail below.
[0040] In Fig. 2-2b are schematic perspective views of a first embodiment of the isolating unit 11 of the isolating terminal 1 according to the invention according to Fig. 1 shown in different positions. Fig. 3-3b show schematic perspective views of the actuating device 10 and the switching device 9 of the first embodiment according to Fig. 2-2b in different positions without housing. Fig. 4-4b represent schematic perspective views of the actuating device 10 and the switching device 9 according to Fig. 3-3b in different positions with housing. Fig. 5 shows a schematic perspective view of individual parts of the actuating device 10 and the switching device 9 of the first embodiment according to Fig. 2-2b .
[0041] Shown are the isolating units 11 of two isolating terminals 1 arranged next to each other. Fig. 2 , Fig. 3 and Fig. 4 show the connection position of the separating units 11. The separation position of the separating units 11 is shown in Fig. 2a , Fig. 3a and Fig. 4a shown. Fig. 2b , Fig. 3b and 4b Each shows a separating unit 11 of the two isolating terminals 1 in the disconnected position and a separating unit 11 in the connected position. It is clearly visible which isolating terminal is in the disconnected position and which is in the connected position.
[0042] In the first embodiment, the switching device 9 and the actuating device 10 comprise a common sliding element 101. The sliding element 101 is mounted in the separating unit 11 in a manner not shown in detail, i.e., it is longitudinally displaceable, and is arranged here at right angles to an imaginary longitudinal axis of the connecting sections 5, 8 of the conductor rails 4, 7. The sliding element 101 is rod-shaped with a substantially rectangular cross-section.
[0043] The sliding element 101 comprises an actuating portion 101a at an upper end, a switching end 101b at a lower end, a toothing 101c in the form of a rack portion on a longitudinal side, and a guide portion 101d on a longitudinal side opposite the longitudinal side with the toothing 101c.
[0044] The guide section 101d is a type of longitudinal web, which forms a locking web of the sliding element 101 in the bridge holder 13 for locking the short-circuit bridge thus formed in the disconnected position with the contact section 91 of the contact plate 90 in the bridge contact sections 14. The guide section 101d can also be extended further upwards, whereby it already engages in the guide surface (not designated) of the bridge holder 13. This is not shown, but in conjunction with the Figuren 3 bis 3b , 4 bis 4b and 5 easy to imagine.
[0045] The narrow end face (not labeled) of the guide section 101d, which points upwards towards the actuating section 101a of the sliding element 101, can form an (additional) position indicator of the isolating terminal 1 when in the disconnected position with the surface 12 of the bridge contact holder 13. Thus, in one case, this end face of the guide section 101d can be aligned with the surface 12 of the bridge contact holder 13 in the disconnected position and, for example, be colored as a visible portion, thereby indicating the disconnected position. In the other case specified above, in which the guide section 101d is extended further upwards, the connected position can be indicated by the end face being aligned with the surface 12 of the bridge contact holder 13. In the disconnected position, the upper, extended portion of the guide section 101d then protrudes clearly from the surface 12 of the bridge contact holder 13 and thus indicates the disconnected position.
[0046] The switching device 9 has a contact plate 90, which is designed as a blade contact with three contact sections 91, 91a, and 92. These three contact sections 91, 91a, and 92 are electrically connected to one another and fastened to the sliding element 101 in the region of the switching end 101a. Two contact sections 91 and 91a are arranged on one longitudinal side of the sliding element 101, which faces the first connecting section 5, and the contact section 92 is located on the opposite longitudinal side of the sliding element 101, which faces the second connecting section 8.
[0047] The contact sections 91 and 91a interact with a contact fork 5a of the connecting section 5 of the first conductor rail 4. Another contact fork 8a at the end of the connecting section 8 of the second conductor rail 8 is opposite the contact fork 5a and interacts with the contact section 92 of the contact plate 90.
[0048] A bridge contact fork 14 is arranged above the contact fork 5a. The bridge contact fork 14 is attached to a bridge holder 13 with another bridge contact fork 14 arranged parallel to it. The bridge contact forks 14 are electrically connected to each other.
[0049] The sliding element 101 is coupled to a limit slide 104 via a gear mechanism. The gear mechanism comprises the toothing 101c (rack) of the sliding element 101, a rotatable transmission element 103 with a corresponding toothing, and another toothing 104a (rack) of the limit slide 104.
[0050] The sliding element 101 engages with the transmission element 103 via its toothing 101c. The transmission element 103 is designed as a spur gear and is mounted rotatably about an axis 103a in the lateral walls 15 of the separating section 2c and in a body 15b.
[0051] Furthermore, the transmission element 103 engages with the limit slide 104 via its toothing 104a. The limit slide 104 is arranged longitudinally displaceably opposite the sliding element 101 in a guide section 15c of the separating section 2c. The guide section 15c also forms stops for the longitudinal displacement of the limit slide 104.
[0052] The sliding element 101 can be adjusted from the connecting position to the separating position and back again by means of its actuating section 101a.
[0053] In the connected position, the contact plate 90 is in electrically conductive connection with the contact fork 5a of the first conductor rail 4. At the same time, the contact section 92 of the contact plate 90 is in electrically conductive connection with the contact fork 8a of the second conductor rail 7, thus establishing an electrically conductive connection between the contact forks 5a and 8a.
[0054] In addition, the guide section 101d is slidably guided in the bridge contact fork 14 and in the bridge contact holder 13. The guide section 101d is electrically non-conductive.
[0055] In the connected position, a visible portion 102 of the actuating portion 101a of the sliding element 101 is aligned with a surface 12 of a portion of the housing 2. The portion of the housing 2 is, for example, the top side of the wall 15 of the housing 2. A surface 12 is also arranged on the top side of the bridge holder 13. The bridge holder 13 is a component of the housing 2 and is inserted therein.
[0056] By pushing the limit slide 104, the sliding element 101 is moved upward in its longitudinal direction via the transmission element 103 into the disconnected position. The longitudinal movement of the limit slide 104 is defined in the guide section 15c by a stop for the disconnected position and by a stop of the sliding element 101 for the connected position. In the disconnected position, the contact forks 5a and 8a are separated because the contact plate 90 with its contact section 92 is pulled upward out of the contact fork 8a. However, the extended contact section 91a remains in contact with the contact fork 5a and forms a so-called drag contact.
[0057] In the disconnected position, the upper contact section 91 of the contact plate 90 is in electrically conductive contact with the bridge contact fork 14. By means of the extended contact section 91a as a trailing contact, the bridge contact fork 14 and the contact fork 5a of the first conductor rail 5 are now electrically connected. The guide section 101d is guided in a longitudinal groove in the bridge contact holder 13.
[0058] In the separation position, the actuating section 101a of the sliding element 101 protrudes visibly from the surface 12 of the separation section 2c with a viewing section 102.
[0059] In the embodiment shown with the two isolating sections 2c of the two isolating terminals 1, in the isolating position of both isolating terminals 1, both first conductor rails 5 are electrically connected via the bridge contact forks 14.
[0060] Fig. 6-6b show schematic perspective views of a second embodiment of the separating unit 11 of the separating terminal 1 according to the invention according to Fig. 1 in different positions. Fig. 7-7b show schematic perspective views of the actuating device 10 and the switching device 9 of the second embodiment according to Fig. 6-6b in different positions without housing. Fig. 8-8b represent schematic perspective views of the actuating device 10 and the switching device 9 according to Fig. 7-7b in different positions with housing. Fig. 9 shows a schematic perspective view of individual parts of the actuating device 10 and the switching device 9 of the second embodiment according to Fig. 6-6b .
[0061] Shown are the isolating units 11 of two isolating terminals 1 arranged next to each other. Fig. 6 , Fig. 7 and Fig. 8 show the connection position of the separating units 11. The separation position of the separating units 11 is shown in Fig. 6a , Fig. 7a and Fig. 8a shown. Fig. 6b , Fig. 7b and 8b Each shows a separating unit 11 of the two isolating terminals 1 in the disconnected position and a separating unit 11 in the connected position. It is clearly visible which isolating terminal is in the disconnected position and which is in the connected position.
[0062] In the second embodiment, the switching device 9 and the actuating device 10 are separate. The switching device 9 comprises the linearly movable sliding element 101 with the switching end 101b, the rack toothing 101c, the guide section 101d, and the contact plate 90 with the contact sections 91, 91a, and 92. Furthermore, the separating unit 11 also has the bridge contact forks 14 with the bridge holder 13. The description of their structure and function has already been given above and will not be repeated here.
[0063] In contrast to the first embodiment, the sliding element 101 of the second embodiment has an end portion 101e without an actuating portion and without a viewing portion.
[0064] The actuating device 10 comprises a separate actuating element 105, which is coupled to the sliding element 101 via a toothed system. The actuating element 105 has an actuating section 105a with a viewing section 102 and a quarter-circle-shaped toothed segment 105c. The actuating element 105 is arranged pivotably about an axis 105b. The pivot angle of the actuating element 105 is defined by stops, e.g., contact section 15d, in the body 15b.
[0065] The toothed segment 105c engages with the rack-shaped toothing 104c of the sliding element 101.
[0066] In the connected position, the visible portion 102 of the actuating portion 105a of the actuating element 105 is aligned with a surface 12 of a portion of the housing 2. The portion of the housing 2 is, for example, the top side of the wall 15 of the housing 2. Furthermore, the portion of the housing 2 here is also the top side of the bridge holder 13, on which the surface 12 is arranged. The actuating portion 105a rests with the underside of the visible portion 102 on the end face of the end portion 101e of the sliding element 101.
[0067] The connection position of the sliding element 101 with the contact plate 90 is as described in the first embodiment.
[0068] By pivoting the actuating section 105a of the actuating element 105, the latter is pivoted (here clockwise) about the axis 105b. In doing so, the sliding element 101, which engages with the toothed segment 105c, is linearly displaced upward into the disconnected position, whereby, as described above in the first embodiment, the electrically conductive connection of the contact forks 5a and 8a is removed, i.e., separated.
[0069] In the separated position, both the actuating section 105a with the visible section 102 of the actuating element 105 and the upper end section 101e of the sliding element 101 protrude clearly from the surface 12 of a section of the housing 2 and here also from the surface 12 of the bridge holder 13.

Fig. 11-11b show schematic perspective views of the actuating device 10 and the switching device 9 of the second embodiment according to Fig. 10-10b in different positions without housing.

In Fig. 14 A schematic perspective view of components of a lever gear is shown.
[0071] Shown are the isolating units 11 of two isolating terminals 1 arranged next to each other. Fig. 10 , Fig. 11 and Fig. 12 show the connection position of the separating units 11. The separation position of the separating units 11 is shown in Fig. 10a , Fig. 11a and Fig. 12a shown. Fig. 10b , Fig. 11b and 12b Each shows a separating unit 11 of the two isolating terminals 1 in the disconnected position and a separating unit 11 in the connected position. It is clearly visible which isolating terminal is in the disconnected position and which is in the connected position.
[0072] In the third embodiment, the switching device 9 and the actuating device 10 are also designed separately. The switching device 9 comprises the linearly movable sliding element 101 with the switching end 101b and the upper end section 101e. The contact plate 90 with the contact sections 91, 91a, and 92 is implemented as in the first and second embodiments. The separating unit 11 is also provided with the bridge contact forks 14 with the bridge holder 13. The description of its structure and function has already been given above.
[0073] As in the second embodiment, the sliding element 101 of the third embodiment has the end section 101e without an actuating section and without a viewing section.
[0074] In contrast to the second embodiment, the end section 101e is laterally widened with a nose-shaped connecting section 101f.
[0075] On both long sides of the sliding element 101, which point outwards towards the wall 15, longitudinally extending guide sections 101g are formed over the entire length of the sliding element 101, with which the sliding element 101 is guided in the walls 15 in a linearly movable manner.
[0076] In contrast to the second embodiment, the actuating device 10 comprises a lever mechanism with an actuating lever 106 and a transmission lever 107.
[0077] The actuating lever 106 has an actuating end 106a with the viewing section 102 and a bearing end 106b. The actuating lever 106 is pivotally mounted on a pivot axis 106c on a body (not shown) of the separating unit 11 via the bearing end 106b. The bearing end 106b is arranged above the end section 101e of the sliding element 101, with the pivot axis 106c being aligned with a longitudinal axis of the sliding element 101.
[0078] The actuating end 106a of the actuating lever 106 is pivotally connected to a drive end 107a of the transmission lever 107 about a joint axis 106d. The transmission lever 107 extends downward from the actuating lever 106 to the nose-shaped connecting portion 101f of the sliding element 101 and is pivotally coupled to this connecting portion 101f via an output end 107b about an output joint axis 107c.
[0079] In the connecting position, both the visible portion 102 of the actuating portion 105a of the actuating lever 105a and the largest part of the surface of the actuating lever 105 are aligned with the surface(s) 12a of the walls 15 of the separating unit 11. The walls 15 can be part of the housing 2. The transmission lever 106 rests with its underside against a contact portion 15d of the separating unit 11 as a stop.
[0080] The connection position of the sliding element 101 with the contact plate 90 is as described in the first embodiment.
[0081] By pivoting the actuating portion 106a of the actuating lever 106, the lever is pivoted (here counterclockwise) about the stationary hinge axis 106c. The transmission lever 107 is thereby pulled upward and simultaneously pulls the sliding element 101 upward from the connected position into the disconnected position. As described above in the first embodiment, the electrically conductive connection between the contact forks 5a and 8a is thus severed.
[0082] In the separation position, the actuating lever 106 is pivoted upwards about the stationary joint axis 106c, wherein the actuating end 106a and the visible section 102 protrude clearly from the surface 12 of the separation unit 11 or the separation section 2c or the bridge holder 13.
[0083] The displacement path of the sliding element 101 is realized in the separated position by the end section 101e abutting the underside of the bearing end 106b of the actuating lever 106.
[0084] An assembly of the lever mechanism in the respective axes 106c, 106d, 107c with the operating lever 106 and the transmission lever 107 is the Figur 14 removable. The actuating lever 106 has laterally protruding pivot pins 108 in the axes 106c and 106d. The pivot pins 108 are provided with lateral flat surfaces 108a, which can be easily inserted into corresponding recesses on both sides of the respective pivot bores 109 on the drive end 107a of the transmission lever 107. By rotating the levers 106, 107 relative to each other, an articulated connection is then enabled. This is shown for the pivot axis 106d. The other joints are designed accordingly, which is not shown but is easily imagined. For example, the output end 107b has pivot bores 110 with a recess 110a. With respect to the stationary bearing end 106b, the walls 15 are designed in a corresponding manner.

Fig. 16-16b show schematic perspective views of the actuating device 10 and the switching device 9 of the fourth embodiment according to Fig. 15-15b in different positions without housing.

[0086] Shown are the isolating units 11 of two isolating terminals 1 arranged next to each other. Fig. 15 , Fig. 16 and Fig. 17 show the connection position of the separating units 11. The separation position of the separating units 11 is shown in Fig. 15a , Fig. 16a and Fig. 17a shown. Fig. 15b , Fig. 16b and 17b Each shows a separating unit 11 of the two isolating terminals 1 in the disconnected position and a separating unit 11 in the connected position. It is clearly visible which isolating terminal is in the disconnected position and which is in the connected position.
[0087] In contrast to the previous embodiments, the contact fork 8a of the second conductor rail 7 is not arranged opposite the contact fork 5a of the first conductor rail, but is cranked upwards, ie arranged at a distance upwards.
[0088] Furthermore, the bridge contact fork(s) 14 is / are arranged opposite the contact fork(s) 8a and bent towards them.
[0089] In the fourth embodiment, the switching device 9 and the actuating device 10 are formed together as in the first embodiment.
[0090] The switching device 9 has the contact plate 90 in an elongated, knife-like shape. The contact plate 90 consists entirely of an electrically conductive contact material and comprises the contact sections 91, 91a, and 92 as well as an electrically conductive connecting section 93.
[0091] The contact section 91a is formed on the lower end of the contact plate 90 on the side facing the contact fork 5a. The contact section 91 is formed opposite this on the other side.
[0092] The contact sections 91, 91a interact with the contact fork 5a.
[0093] The contact section 92 is formed on both sides of the upper end of the contact plate 90, like the sections 91 and 91a.
[0094] The contact sections 91, 91a and 92 are electrically connected via the connecting section 93.
[0095] The contact plate 90 is arranged in its lower region so as to be pivotable about a pivot axis 111b in the separating unit 11 between the walls 15 and is held stationary in a bearing section 15e.
[0096] The upper end of the contact plate 90 is firmly connected to the actuating device 10.
[0097] The actuating device 10 has a switching lever 111 with an actuating end 111a. The viewing section 102 is attached to the actuating end 111a.
[0098] In the connected position, the switching lever 111 is positioned with its actuating end 111 essentially vertically and rests against a housing stop 15f. The visible portion 102 is aligned with the surface 12 of the housing stop 15f. The housing stop 15f is part of the housing 2.
[0099] The right-hand side area of contact section 92 of contact plate 90 is in contact with contact fork 8a in the connected position. Contact section 91 of contact plate 90 is in contact with contact fork 5a. This creates an electrically conductive connection between contact fork 5a, contact section 91, connecting section 93, contact section 92, and contact fork 8a in the connected position.
[0100] By pivoting the actuating portion 111a of the switching lever 111, the latter is pivoted (here counterclockwise) together with the contact plate 90 about the stationary pivot axis 111b. The contact portion 92 thereby switches from the contact fork 8a to the bridge contact fork 14. The contact portion 91 leaves the contact fork 5a, but the connected contact portion 91a remains in contact with the contact fork 5a as a trailing contact.
[0101] In the disconnected position, the switching lever 111 with the contact plate 90 is pivoted to the left about the fixed pivot axis 111b, with the actuating end 111a resting against the bridge holder 13. The visible portion 102 protrudes from the surface 12a of a portion of the housing 2. The portion of the housing 2 is, for example, the top side of the wall 15 of the housing 2. Furthermore, the portion of the housing 2 here is also the top side of the bridge holder 13, on which the surface 12 is arranged.
[0102] In the disconnected position, a separation is thus established between the contact forks 5a and 8a, i.e., between the first conductor rail 4 and the second conductor rail 7. At the same time, the contact fork 5a of the first conductor rail 4 and the bridge contact fork 14 are electrically connected via the contact plate 90.
[0103] The actuating end 111a of the shift lever 111 can be adjusted manually, with a tool or with an actuating element 16. This is Fig. 19 und 19a in schematic perspective views of the separation unit 11 of the fourth embodiment according to Fig. 15-15b with the actuating element 16.
[0104] The actuating element 16 has a body 16a for manual actuation and a plug-in section 16b, with which the actuating element 16 can be inserted into the actuating end 111a provided with a recess for this purpose. The actuating element 16 can have one, two, or more plug-in sections 16b. The actuating element 16 enables the synchronous actuation of two or more separation points and is also conceivable in the principles presented so far.
[0105] Fig. 20 shows a schematic perspective view of the isolating terminal 1 according to the invention in a double row arrangement with the fourth embodiment of the isolating unit 11 according to Fig. 15-15b .
[0106] Schematic perspective views of arrangements 100 of isolating terminals 1 according to the invention with the fourth embodiment of the isolating unit 11 according to Fig. 15-15b are in the Figuren 21 und 21a shown in arrays 100.
[0107] It is clearly visible which isolating terminals 1 are in the disconnected position and which are in the connected position, since the corresponding actuating ends of the switching levers 111 with the visible sections 102 in the disconnected position clearly protrude from the surface 12, 12a of the housing 2 and the bridge support 13 of the isolating units 11, whereby they no longer lie on the housing stops 15f.
[0108] The invention is not limited by the embodiments described above, but can be modified within the scope of the claims.
