Description

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.

Disconnect terminals of this type are used in different applications.

For example, describes the document DE 197 48 640 C1 a measuring disconnect terminal arrangement for the operation of current transformers, in which busbar pieces are provided with conductor connections and contacts. Separation is required to connect current measuring devices or external voltages, for example. This is done by a disconnector that interacts with the contacts.

DE 44 44 551 A1 describes a current transformer disconnect terminal block with a contact piece in the form of an angle-adjustable contact disk, which ensures by means of a contact drag line that when disconnecting or closing the current passage through the terminal, the secondary side of a connected current transformer can never be open.

The known disconnect terminals have proven themselves. However, it is desirable to further develop these disconnect terminals, with simple, quick and unambiguous detection of the respective switching position of an isolating terminal, i.e. a connection position and a separation position is made possible. At the same time, a compact structure and a small number of components are achieved.

The object of the invention is to solve this problem. The invention solves this problem by the subject matter of claim 1 and by the subject matter of claim 15.

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, the switching device by means of the actuating device from a connecting position in which the first conductor rail and the second conductor rail are electrically conductively connected by the switching device Disconnected position in which the electrically conductive connection of the first conductor rail and the second conductor rail is separated, and is adjustable back. A visible section of the actuating device is aligned in the connected position with a surface of a section of an upper side of the housing or of a part connected to the housing, and the visible section of the actuating device is in the disconnected position clearly visible from a surface of a portion of a top of the housing or a part connected to the housing.

This enables an advantageously clear and quick detection of the switching state of the disconnect terminal.

The section of the housing is, for example, a top of a wall of the housing, a surface on the top of a component of the housing or an inserted part of the housing, e.g. of a bridge holder.

An arrangement according to the invention has at least two of the disconnect terminals described above.

A further arrangement according to the invention of at least two connected disconnect terminals, each disconnect terminal having a housing, a first conductor rail and a second conductor rail, a switching device and an actuating device, the switching device by means of the actuating device from a connecting position in which the first conductor rail and the second conductor rail are electrically conductively connected by the switching device, into a disconnected position, in which the electrically conductive connection of the first conductor rail and the second conductor rail is separated, and can be adjusted back, has a view section of the actuating device, the view section in the connection position having a surface of a Section of an upper side of the housing or of a part connected to the housing is aligned, and wherein the visible section of the actuating device in the separation position from a surface of a section of an upper side e of the housing or a part connected to the housing protrudes clearly, the respective sliding elements and / or limit slides and / or actuating elements being connected to one another by detachable actuating elements in the at least two disconnect terminals in order to enable synchronous actuation. An advantageously simple and quick actuation can thus be achieved.

The switching device has a contact plate made of an electrically conductive contact material with contact sections, a contact section forming a trailing contact. The contact plate can advantageously be simple, e.g. be manufactured as a stamped part.

In the connecting position, the contact plate advantageously connects the conductor rails in an electrically conductive manner via the contact sections. The contact plate is for example a kind of knife contact, which interacts with contact forks on the conductor rails.

It is advantageous if the contact plate in the disconnected position connects the first conductor rail in an electrically conductive manner via the contact section forming the trailing contact and the contact section to a bridge contact. In this way, a simple connection of the respective first conductor rails in the disconnected position can be achieved with a series of disconnect terminals, which e.g. is advantageous for use as current transformer disconnect terminals.

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 structure with a small number of components.

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.

In a further embodiment, the linearly movable sliding element is coupled to a limit slide via a gear, the limit slide defining an adjustment path of the linearly movable slide element in cooperation with stops of a guide section in a body of the housing. An advantage is that a simple limitation of the adjustment path of the sliding element is made possible.

In an alternative embodiment, the switching device has a linearly movable sliding element with the contact plate, the actuating device having a separate actuating element which is coupled to the sliding element via a toothing or another form-fitting drive form. Another form of positive drive can e.g. be a headstock coupling. In this way, there is the advantage of simple manual actuation with little effort.

The actuating element of the actuating device has an actuating section with the viewing section, the actuating element being arranged so as to be pivotable about an axis. A compact structure can thus advantageously be achieved.

In another embodiment, the sliding element (101) can have a guide section (101d) in the form of a web with an end face with the viewing section (102). This can advantageously enable an additional display option for the respective switching position of the disconnect terminal.

In a further alternative embodiment, it is provided that the switching device has a linearly movable sliding element with the contact plate, the actuating device having a separate actuating lever, which has the viewing section and is coupled to the sliding element via a lever mechanism. By means of the lever gear mechanism, advantageous power transmission of manual actuation to the sliding element can be made possible. In addition, defined end positions are easy to achieve.

In a further embodiment, the lever gear has the actuating lever and a transmission lever, the transmission lever being coupled to the sliding element. This results in a simple construction with a small space requirement.

In a still further alternative embodiment, it is provided that the switching device has a switching lever with an actuating end with the viewing section, and that the switching device is formed by the contact plate, the contact plate having an elongated, knife-like shape. Here, an advantageously simple and space-saving design is achieved.

A further embodiment provides that the switching lever of the actuating device is firmly connected to the elongated, knife-like contact plate of the switching device and can be pivoted with the contact plate about a common, stationary switching lever axis. This structure is advantageous because only a small number of components is required. In addition, only a small amount of manual effort is required. A corresponding tool or actuating means can of course also be used.

In a further embodiment, the switching lever rests with its actuating end in the connecting position on a housing stop, the visible section being aligned with a surface of the housing stop, and that the switching lever with the contact plate is pivoted about the fixed pivot axis in the disconnected position and abuts a bridge holder as a stop , wherein the view portion of the operating end of the shift lever protrudes from the surface of the bridge holder as a portion or component of the housing. In this way, a clear and simple detection of the switching status or the switching position of the disconnect terminal can be achieved.

In one embodiment of the arrangement, it is provided that the at least two disconnect terminals jointly form a bridge holder with bridge contacts that are connected to one another are electrically conductively connected. A field of application of the disconnect terminals is thus advantageously expanded.

Further advantageous configurations can be found in the remaining subclaims.

Fig. 1 shows a schematic perspective view of an embodiment of an isolating terminal 1 according to the invention with a block diagram of a switching device 9 and an actuating device 10.

The disconnect terminal 1 comprises a housing 2 with a first connection section 2a, a second connection section 2b and a separating section 2c arranged centrally between them.

A first clamping section 3, which is not described in more detail, for connecting an electrically conductive line, not shown, is arranged in the first connection section 2a. The first clamping section 3 is connected to a first conductor rail 4, which extends with a connecting section 5 into the separating section 2c.

Similarly, in the second connection section 2b, a second clamping section 6, not described in more detail, for the connection of a further electrically conductive line, not shown, is arranged as a mirror image of the first connection section 2a. The second clamping section 6 is connected to a second conductor rail 7, which extends with a connecting section 8 into the separating section 2c.

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 connects the two connecting sections 5 and 8 and thus the first conductor rail 4 and the second conductor rail 8 in an electrically conductive manner, so that the first clamping section 3 is electrically conductively connected to the second clamping section 6.

In a disconnected position of the switching device 9, the two connecting sections 5 and 8 are separated and isolated from one another, i.e. the electrically conductive connection of the two connecting sections 5 and 8 and thus the conductor rails 4 and 8 is canceled or separated.

The switching device 9 is coupled to an actuating device 10. The actuating device 10 is designed to move the switching device 9 from the connecting position into the disconnected position and back. The actuating device 10 is actuated manually and / or with a suitable tool. The respective position, i.e. the connection position and the disconnected position of the switching device 9 are visibly indicated by the actuating device 10. This is carried out in such a way that a visible section 102 of the actuating device 9 in the connected position is aligned with a surface 12, 12a of a section of an upper side of the housing 2 or with a part connected to the casing 2, and that the visible section 102 of the actuating device 9 in the disconnected position protrudes clearly from the surface 12, 12a of a portion of the top of the housing 2 or a part connected to the housing 2.

The switching device 9 and the actuating device 10 coupled to it are arranged in the separating section 2c as a separating unit 11, which in FIG Fig. 1 is marked by dash-double-dotted lines.

In the in Fig. 1 In the example shown, two disconnect terminals 1 are lined up next to one another (it can of course also be more than two disconnect terminals 1). In certain applications of these disconnect terminals 1, it is necessary for the first clamp sections 3, for example, to be short-circuited in the disconnected position of the disconnect terminals 1, ie to be electrically conductively connected to one another. For this purpose, the switching device 9 can connect the first clamping sections 3 to one another in the disconnected position by means of a so-called short-circuit bridge. This is described in detail below.

In Fig. 2-2b are schematic perspective views of a first embodiment of the disconnecting unit 11 of the disconnect terminal 1 according to the invention Fig. 1 shown in different positions. Fig. 3-3b show schematic perspective views of the actuator 10 and the switching device 9 of the first embodiment Fig. 2-2b in different positions without housing. Fig. 4-4b represent schematic perspective representations of the actuating device 10 and the switching device 9 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 Fig. 2-2b .

The separation units 11 of two disconnection terminals 1 arranged side by side are shown in each case. Fig. 2 , Fig. 3 and Fig. 4 each show the connection position of the separation units 11. The separation position of the separation units 11 is in each case in Fig. 2a , Fig. 3a and Fig. 4a shown. Fig. 2b , Fig. 3b and 4b each show a disconnection unit 11 of the two disconnect terminals 1 in the disconnection position and in each case a disconnection unit 11 in the connection position. Here you can clearly see which disconnect terminal is switched in the disconnected position and which is connected in the connected position.

In the first exemplary embodiment, the switching device 9 and the actuating device 10 comprise a common sliding element 101. The sliding element 101 is linearly movable in the separating unit 11 in a manner not shown, i.e. mounted longitudinally displaceable and 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 an essentially rectangular cross section.

The sliding element 101 comprises an actuating section 101a at an upper end, a switching end 101b at a lower end, a toothing 101c in the form of a rack section on a long side and a guide section 101d on a long side which is opposite to the long side with the toothing 101c.

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, it already engaging in the guide surface (not designated) of the bridge holder 13. This is not shown, but in connection with the Figures 3 to 3b , 4 to 4b and 5 easy to imagine.

The narrow end face (not designated) of the guide section 101d which points upward to the actuating section 101a of the sliding element 101 can form an (additional) position indicator of the disconnect terminal 1 with the surface 12 of the bridge contact holder 13 in the disconnected position. 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 can be colored, for example, as a colored visible section, which indicates the disconnected position. In the other case indicated above, in which the guide section 101d is extended further upward, the connection position can be indicated by the end face being aligned with the surface 12 of the bridge contact holder 13. The upper, elongated section of the guide section 101d then stands in the separation position from the surface 12 the bridge contact holder 13 clearly visible and thus indicates the disconnected position.

The switching device 9 has a contact plate 90 which is designed as a knife contact with three contact sections 91, 91a and 92. These three contact sections 91, 91 a and 92 are connected to one another in an electrically conductive manner and fastened to the sliding element 101 in the region of the switching end 101a, two contact sections 91 and 91a being arranged on a longitudinal side of the sliding element 101, which faces the first connecting section 5 the contact section 92 is located on the opposite long side of the sliding element 101, which faces the second connecting section 8.

The contact sections 91 and 91 cooperate 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 faces the contact fork 5a and interacts with the contact section 92 of the contact plate 90.

A bridge contact fork 14 is arranged above the contact fork 5a. The bridge contact fork 14 is fastened to a bridge holder 13 with a further bridge contact fork 14 lying parallel to it. The bridge contact forks 14 are connected to one another in an electrically conductive manner.

The sliding element 101 is coupled to a limiting slide 104 via a gear. The gear has the toothing 101c (rack) of the sliding element 101, a rotatable transmission element 103 with a corresponding toothing and a further toothing 104a (rack) of the limit slide 104.

The toothing 101c engages the transmission element 103 with its toothing 101c. The transmission element 103 is designed as a spur gear and is rotatably mounted about an axis 103a in the side walls 15 of the separating section 2c and in a body 15b.

Furthermore, the transmission element 103 is in engagement with the limit slide 104 with its toothing 104a. The limit slide 104 is arranged to be longitudinally displaceable relative to the slide 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.

The sliding element 101 can be adjusted from the connecting position into the disconnected position and back again by means of its actuating section 101a.

In the connecting 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 and thus establishes an electrically conductive connection of the contact forks 5a and 8a.

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 not electrically conductive.

In the connected position, a visible section 102 of the actuating section 101a of the sliding element 101 is aligned with a surface 12 of a section of the housing 2. The section of the housing 2 is, for example, the top of the wall 15 of the housing 2. A surface 12 is also on the top of the housing Bridge holder 13 arranged. The bridge holder 13 is a component of the housing 2 and used in this.

By pushing the limit slide 104, the slide element 101 is moved upwards in the 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 slide element 101 for the connection position. In the disconnected position, the contact forks 5a and 8a are separated, since the contact plate 90 with its contact section 92 is pulled up 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.

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 drag contact, the bridge contact fork 14 and the contact fork 5a of the first conductor rail 5 are now connected in an electrically conductive manner. The guide section 101d is guided in the bridge contact holder 13 in a longitudinal groove.

In the disconnected position, the actuating section 101a of the sliding element 101 protrudes with a visible section 102 from the surface 12 of the separating section 2c.

In the embodiment shown with the two disconnect sections 2c of the two disconnect terminals 1, in the disconnect position of the two disconnect terminals 1, both first conductor rails 5 are electrically conductively connected via the bridge contact forks 14.

Fig. 6-6b show schematic perspective views of a second embodiment of the disconnection unit 11 of the disconnect terminal 1 according to the invention 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 Fig. 6-6b in different positions without housing. Fig. 8-8b represent schematic perspective representations of the actuating device 10 and the switching device 9 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 Fig. 6-6b .

The separation units 11 of two disconnection terminals 1 arranged side by side are shown in each case. Fig. 6 , Fig. 7 and Fig. 8 each show the connection position of the separation units 11. The separation position of the separation units 11 is in each case in Fig. 6a , Fig. 7a and Fig. 8a shown. Fig. 6b , Fig. 7b and 8b each show a disconnection unit 11 of the two disconnect terminals 1 in the disconnection position and in each case a disconnection unit 11 in the connection position. Here you can clearly see which disconnect terminal is switched in the disconnected position and which is connected in the connected position.

In the second exemplary 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, with the rack toothing 101c, the guide section 101d and the contact plate 90 with the contact sections 91, 91 a and 92. In addition, the separating unit 11 also has the bridge contact forks 14 with the Bridge holder 13 on. The description of the structure and function is already given above and should not be repeated here.

In contrast to the first exemplary embodiment, the sliding element 101 of the second exemplary embodiment has an end section 101e without an actuating section and without a viewing section.

The actuating device 10 comprises a separate actuating element 105, which is coupled to the sliding element 101 via a toothing. The actuating element 105 has an actuating section 105a with a viewing section 102 and a quarter-circular tooth segment 105c. The actuating element 105 is arranged so as to be pivotable about an axis 105b. A swivel angle of the actuator 105 is fixed in the body 15b by stops, for example contact section 15d.

The toothed segment 105c is in engagement with the rack-shaped toothing 104c of the sliding element 101.

In the connected position, the visible section 102 of the actuating section 105a of the actuating element 105 is aligned with a surface 12 of a section of the housing 2. The section of the housing 2 is, for example, the top of the wall 15 of the housing 2. In addition, the section of the housing 2 is also here Top of the bridge holder 13 on which the surface 12 is arranged. The actuating section 105a rests with the underside of the viewing section 102 on the end face of the end section 101e of the sliding element 101.

The connecting position of the sliding element 101 with the contact plate 90 is as described in the first embodiment.

The actuating section 105a of the actuating element 105 is pivoted (here clockwise) about the axis 105b by means of a pivoting actuation. The sliding element 101, which is in engagement with the toothed segment 105c, is linearly shifted upwards into the disconnected position, the electrically conductive connection of the contact forks 5a and 8a being canceled, as described above in the first exemplary embodiment, is separated.

In the disconnected 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.

The separation position of the separation units 11 is in each case in Fig. 10a , Fig. 11a and Fig. 12a shown. Fig. 10b , Fig. 11b and 12b each show a disconnection unit 11 of the two disconnect terminals 1 in the disconnection position and in each case a disconnection unit 11 in the connection position. Here you can clearly see which disconnect terminal is switched in the disconnected position and which is connected in the connected position.

In the third exemplary embodiment, the switching device 9 and the actuating device 10 are also formed 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 exemplary embodiments. The separating unit 11 is also provided here with the bridge contact forks 14 with the bridge holder 13. The description of the structure and function is already given above.

As in the second exemplary embodiment, the sliding element 101 of the third exemplary embodiment has the end section 101e without an actuating section and without a viewing section.

In contrast to the second exemplary embodiment, the end section 101 e is widened laterally with a nose-shaped connecting section 101 f.

On both longitudinal sides of the sliding element 101, which point outwards to 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 a linearly movable manner in the walls 15.

In contrast to the second exemplary embodiment, the actuating device 10 comprises a lever gear with an actuating lever 106 and a transmission lever 107.

The operating lever 106 has an operating end 106a with the viewing section 102 and a bearing end 106b. With the bearing end 106b, the actuating lever 106 is attached in a pivotable manner in a hinge axis 106c to a body of the separating unit 11, which is not designated. The bearing end 106b is arranged above the end section 101e of the sliding element 101, the hinge axis 106c here being aligned with a longitudinal axis of the sliding element 101.

The actuating end 106a of the actuating lever 106 is pivotally connected in a hinge axis 106d to a drive end 107a of the transmission lever 107. The transmission lever 107 extends downward from the actuating lever 106 to the nose-shaped connecting section 101f of the sliding element 101 and is coupled to this connecting section 101f via an output end 107b so as to be pivotable about an output joint axis 107c.

In the connecting position, both the visible section 102 of the actuating section 105a of the actuating lever 105a and the major 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 underside of the transmission lever 106 lies against a contact section 15d of the separating unit 11 as a stop.

The connecting position of the sliding element 101 with the contact plate 90 is as described in the first embodiment.

By means of a pivoting actuation of the actuating section 106a of the actuating lever 106, the latter is pivoted (here in a counterclockwise direction) about the fixed articulated axis 106c. The transmission lever 107 is pulled upwards and at the same time pulls the sliding element 101 upwards from the connecting position into the disconnected position. As described above in the first exemplary embodiment, the electrically conductive connection of the contact forks 5a and 8a is thus separated.

In the disconnected position, the actuating lever 106 is pivoted upward about the fixed hinge axis 106c, the actuating end 106a and the viewing section 102 protruding clearly from the surface 12 of the separating unit 11 or the separating section 2c or the bridge holder 13.

The displacement path of the sliding element 101 is realized in the disconnected position by the end section 101e abutting the underside of the bearing end 106b of the actuating lever 106.

An assembly of the lever gear in the respective axes 106c, 106d, 107c with the actuating lever 106 and the transmission lever 107 is the Figure 14 removable. The actuating lever 106 has pivot pins 108 projecting laterally in the axes 106c and 106d. The hinge pins 108 are provided with lateral flat surfaces 108a, which can easily be inserted into recesses, corresponding to them on both sides, of respective joint bores 109 on the drive end 107a of the transmission lever 107. By turning the levers 106, 107 against each other then an articulated connection is made possible. This is shown for the hinge axis 106d. The other joints are designed accordingly, which is not shown but is easy to imagine. The output end 107b has joint bores 110 with a recess 110a. With regard to the fixed bearing end 106b, the walls 15 are designed in a corresponding manner.

Figures 16-16b show schematic perspective views of the actuating device 10 and the switching device 9 of the fourth embodiment 15-15b in different positions without housing. Figures 17-17b represent schematic perspective representations of the actuating device 10 and the switching device 9 Figures 16-16b in different positions with housing. Fig. 18 shows a schematic perspective view of individual parts of the actuating device 10 and the switching device 9 of the fourth embodiment 15-15b .

The separation units 11 of two disconnection terminals 1 arranged side by side are shown in each case. Fig. 15 , Fig. 16 and Fig. 17 each show the connection position of the separation units 11. The separation position of the separation units 11 is in each case in 15a , Fig. 16a and Fig. 17a shown. 15b , Fig. 16b and 17b each show a disconnection unit 11 of the two disconnect terminals 1 in the disconnection position and in each case a disconnection unit 11 in the connection position. Here you can clearly see which disconnect terminal is switched in the disconnected position and which is connected in the connected position.

In contrast to the previous exemplary 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, i.e. spaced upwards.

Furthermore, the bridge contact fork (s) 14 are / are arranged opposite the contact fork (s) 8a and are bent toward them.

In the fourth exemplary embodiment, the switching device 9 and the actuating device 10 are formed together as in the first exemplary embodiment.

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 and an electrically conductive connecting section 93.

At the lower end of the contact plate 90, the contact section 91a is formed on the side facing the contact fork 5a. Opposing this on the other side, the contact section 91 is formed.

The contact sections 91, 91a cooperate with the contact fork 5a.

The contact section 92 is also formed on both sides at the upper end of the contact plate 90 like the sections 91 and 91a.

The contact sections 91, 91 a and 92 are electrically conductively connected via the connecting section 93.

In its lower region, the contact plate 90 is arranged such that it can be pivoted about a pivot axis 111b in the separating unit 11 between the walls 15 in a bearing section 15e.

The upper end of the contact plate 90 is fixedly connected to the actuating device 10.

The actuating device 10 has a shift lever 111 with an actuating end 111a. The view portion 102 is attached to the operating end 111a.

In the connected position, the shift lever 111 is essentially vertical with its actuating end 111 and bears against a housing stop 15f. The viewing section 102 is flush with the surface 12 of the housing stop 15f. The housing stop 15f is part of the housing 2.

The right side region of the contact section 92 of the contact plate 90 is in contact with the contact fork 8a in the connecting position. The contact section 91 of the contact plate 90 is in contact with the contact fork 5a. An electrically conductive connection between the contact fork 5a, the contact section 91, the connecting section 93, the contact section 92 and the contact fork 8a is thus realized in the connecting position.

By means of a pivoting actuation of the actuating section 111a of the switching lever 111, this (in the counterclockwise direction here) is pivoted together with the contact plate 90 about the stationary pivot axis 111b. The contact section 92 changes from the contact fork 8a to the bridge contact fork 14. The contact section 91 leaves the contact fork 5a, but the contact section 91a connected to it remains in contact with the contact fork 5a as a drag contact.

In the disconnected position, the switching lever 111 with the contact plate 90 is pivoted to the left about the fixed pivot axis 111b, the actuating end 111a being located on the bridge holder 13 at the stop. The view section 102 protrudes from the surface 12a of a section of the housing 2. The section of the housing 2 is, for example, the top of the wall 15 of the housing 2. In addition, the section of the housing 2 here is also the top of the bridge holder 13 on which the surface 12 is arranged.

In the disconnected position, there is a separation between the contact forks 5a and 8a, i.e. produced between the first conductor rail 4 and the second conductor rail 7. At the same time here the contact fork 5a of the first conductor rail 4 and the bridge contact fork 14 are electrically conductively connected via the contact plate 90.

The actuating end 111a of the shift lever 111 can be adjusted manually, with a tool or with an actuating element 16. This is in 19 and 19a in schematic perspective views of the separation unit 11 of the fourth embodiment 15-15b shown with the actuator 16.

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 for this purpose. The actuating element 16 can have a plug section 16b, two or more. The actuating element 16 enables the synchronous actuation of two or more separation points and is also conceivable in the principles presented so far.

Fig. 20 shows a schematic perspective view of the disconnect terminal 1 according to the invention in a double-row arrangement with the fourth embodiment of the disconnect unit 11 15-15b .

Schematic perspective views of arrangements 100 of disconnect terminals 1 according to the invention with the fourth embodiment of the disconnect unit 11 according to 15-15b are in the Figures 21 and 21a shown in rows 100.

It is clearly visible which disconnect terminals 1 are in the disconnect position and which are in the connect position, since the associated actuating ends of the shift lever 111 with the visible sections 102 in the disconnect position are clearly visible from the surface 12, 12a of the housing 2 and the bridge girder 13 of the disconnect units 11 protrude, wherein they are no longer on the housing stops 15f.
