Background Art

[0003] Electrical terminals have been known for decades and are used in millions of applications in the wiring of electrical installations and devices. The terminals are usually clipped onto a support rail, which is itself usually arranged in a switch cabinet in multiple forms. The basic type of terminal is a connection terminal with at least two conductor connection elements, which are electrically connected to each other via an electrically conductive connection rail, a busbar. In addition to this basic type, which is also often referred to as a through terminal, there are many different types of terminal that are specifically adapted to the respective application scenario. Examples include safety lead terminals, fuse terminals, component terminals, and mounting terminals.

[0004] In particular, in terminal blocks for detection and measurement technology, a variety of switching, isolating and detection tasks are usually implemented. Depending on their application, such terminal blocks are often also called isolating terminals. With the help of isolating elements arranged in the terminal housing of the isolating terminal, such as isolating blades or isolating slides, two parts of the busbar can be selectively connected to each other or isolated from each other, so that reliable isolation of two circuits can be achieved.

[0005] DE 41 06 555 A1 discloses an electrical connecting terminal in which two parts of a busbar can be separated by an isolating point. The connecting terminal described therein is a double-layer terminal having two busbars extending one above the other in a terminal housing, wherein the two busbars can be separated by an isolating point accessible from the upper side of the connecting terminal. The isolating point is designed as a blade isolating point having an isolating blade pivotably mounted in the housing.

[0006] An isolating terminal as described at the outset is known from EP 4 007 075 A1, which has not only one isolating point, but two isolating points, via which three busbar parts can be connected to one another or isolated from one another. Two bridging shafts are arranged between the two isolating points, via which the middle busbar part can be connected to the potential at the feed terminal by means of inserted bridging elements. In the known terminal, maintenance work can be simplified, since the conductor connections can be individually and independently of one another isolated from the potential connected to the second busbar part in the middle. Although such terminal has proven effective in practice, a plurality of terminal blocks are often required in order to be able to implement the desired functions and wiring. Summary of the invention

[0007] Therefore, an object of the present invention is to provide a connection terminal as mentioned at the beginning, which can realize multiple functions, so that different application scenarios can be covered with as few connection terminals as possible.

[0008] In the connection terminal described at the outset, this object is achieved by means of the features of claim 1 in that at least one functional shaft is arranged in the terminal housing between the first conductor connection part and the first isolating point, and correspondingly at least one connection possibility for a functional element is constructed in the first busbar part, and at least one functional shaft is arranged in the terminal housing between the second conductor connection part and the second isolating point, and correspondingly at least one connection possibility for a functional element is constructed in the third busbar part.

[0009] The terminal according to the invention has at least three functional shafts in addition to the two isolation points, wherein the functional shafts are arranged in such a way that at least one functional shaft is constructed on both sides of the two isolation points. Therefore, in the terminal according to the invention, at least one functional shaft is arranged between the two isolation points, and additionally at least one functional shaft is arranged between the isolation point and the conductor connection part adjacent thereto. As a result, in the terminal according to the invention, it is possible not only to connect or isolate the potential applied to the middle busbar part to one of the two conductor connections via the corresponding isolation points, but also to connect the potential to the other terminal via a bridging element inserted into one of the two other functional shafts. If, for example, a test plug is inserted into one of the two other functional shafts instead of a bridging element, there is an alternative possibility of testing the individual current paths.

[0010] According to an advantageous design of the terminal block of the present invention, two functional shafts are respectively constructed in the terminal housing not only between the first conductor connection part and the first isolating point, but also between the second conductor connection part and the second isolating point. Correspondingly, two connection possibilities for each functional element are respectively constructed not only in the first busbar part, but also in the third busbar part. In addition, according to another advantageous design, two functional shafts are also arranged in the terminal housing between the two isolating points, and correspondingly two connection possibilities for each functional element are constructed in the second busbar part. According to a preferred design, the terminal block thus has three dual-function shafts, wherein one dual-function shaft is respectively arranged between the first conductor connection part and the first isolating point, between the second conductor connection part and the second isolating point, and between the two isolating points.

[0011] The connection possibilities for the respective functional elements formed in the respective busbar parts are preferably formed as openings in the busbar, into which the ends of the respective functional elements can be inserted in such a way that they electrically contact the respective busbar parts. In this case, the shape of the openings in the busbar parts is matched to the shape of the ends of the functional elements, so that screwless assembly of the functional elements by simple insertion into the openings is possible.

[0012] The two isolating points formed in the terminal housing of the connecting terminal are designed in such a way that they are basically suitable for accommodating different functional elements. For example, a separate isolating plug can be inserted into the isolating point. Alternatively, a fuse plug or a component plug can also be inserted into the isolating point. Depending on the type of functional element inserted into the isolating point, the connecting terminal can thus assume different functions and thus be used for different application scenarios.

[0013] According to an advantageous design of the terminal block of the present invention, the isolating blade is pivotably arranged in the terminal housing as a functional element in the region of at least one of the two isolating points. Thus, in the first position of the isolating blade, two adjacent busbar components, i.e., either the first busbar component and the second busbar component at the first isolating point, or the second busbar component and the third busbar component at the second isolating point, can be connected to each other via the isolating blade. In the second position of the isolating blade, the two corresponding busbar components are separated from each other. By pivotably arranging the isolating blade in the terminal housing, the terminal block can be simply used as an isolating terminal, and the assembler does not have to use a corresponding isolating plug as a functional element.

[0014] As mentioned at the outset, the terminal according to the invention has two conductor connections. However, this does not exclude that the terminal may also have more than two conductor connections, for example, two conductor connections at each end of the terminal housing, i.e., two conductor connections each electrically conductively connected to the first busbar part or the third busbar part.

[0015] According to one embodiment of the connecting terminal according to the invention, the first conductor connection part and / or the second conductor connection part has a conductor connection element. The respective conductor connection element here respectively cooperates with the busbar part in such a way that the end of the conductor can be connected to the corresponding busbar part, that is, to the first busbar part and / or the second busbar part, by means of the conductor connection element. Different types of conductor connection elements are possible here, in particular threaded joints, tension spring joints, spring force clamping joints, crimping joints or cutting joints.

[0016] According to a preferred design of the present invention, the conductor connection element is constructed as a spring force clamping joint, which respectively has a clamping spring with a clamping leg and a busbar, and the busbar and the clamping leg together form a clamping position for the conductor to be connected. Here, the end of the first busbar component facing the first conductor connection part and the end of the third busbar component facing the second conductor connection part are respectively used as the busbars of the corresponding spring force clamping joint. In order to simply open the corresponding clamping position, an operating element, especially an operating button, can be movably arranged in the terminal housing. Alternatively or additionally, the clamping legs of the clamping spring can also be pre-tensioned so that when the conductor end is inserted into the clamping position, the conductor is automatically clamped in the clamping position.

[0017] According to an alternative design of the connection terminal, the first conductor connection part and / or the second conductor connection part can have a plug-in position for connecting a plug. Therefore, the connection terminal can be designed as a pluggable connection terminal at least on one side. Here, the plug-in position is formed by the end of the first busbar part or the third busbar part facing the first conductor connection part or the second conductor connection part. In addition, the plug-in position is preferably designed as a plug pin, onto which the corresponding contact socket in the connection plug can be plugged.

[0018] In principle, in the terminal block of the present invention, the aforementioned possible designs of the conductor connection part can be combined with each other. Therefore, in the terminal block, one conductor connection part can have a conductor connection element, while the other conductor connection part has a plug-in position. Similarly, two or all conductor connection parts can each have a conductor connection element or each have a plug-in position. If the conductor connection parts all have conductor connection elements, they are usually all constructed in the same way, that is, for example, all are constructed as spring force clamping joints or threaded joints, but the present invention is not limited to this. Therefore, different types of conductor connection elements can also be provided in the terminal block according to the application scenario.

[0019] In addition to individual connecting terminals, the invention also relates to a connecting terminal block having at least two connecting terminals arranged side by side, a feed terminal for connecting a potential, and at least one bridging element. The feed terminal has a terminal housing, two conductor connections, a busbar, and at least one functional shaft constructed in the terminal housing between the two conductor connections. Corresponding to the functional shaft, a connection possibility for a bridging element is constructed in the busbar of the feed terminal, so that the connecting terminal can be connected to the potential of the feed terminal via the at least one bridging element.

[0020] Regarding the advantageous design of the conductor connection part, at least one functional shaft, and the connection possibility in the busbar of the feed terminal, reference can be made to the above description of the connection terminal according to the invention. Here, both conductor connection parts of the feed terminal preferably have a conductor connection element, which is especially designed as a spring force clamping joint.

[0035] Figure 1A perspective view of a connection terminal 1 in the form of a blade-type isolating terminal according to the invention is shown, which can be used in particular for detection and measurement technology. The connection terminal 1 has a terminal housing 2, which is usually made of plastic, in which two conductor connections 3, 4 and a busbar consisting of three busbar parts 5, 6, 7 are arranged. The individual busbar parts 5, 6, 7 are arranged in the terminal housing 2 one behind the other in the longitudinal direction L of the connection terminal 1 at a distance from each other. Figure 1 In the view of FIG. 1 , the first conductor connection portion 3 on the left is electrically conductively connected to the first busbar component 5 , and the second conductor connection portion 4 on the right is electrically conductively connected to the third busbar component 7 .

[0036] The connecting terminal 1 shown in the drawings has two isolating points 8 and 9 arranged one behind the other, wherein the first isolating point 8 is constructed or arranged between the first busbar component 5 and the middle second busbar component 6, and the second isolating point 9 is constructed or arranged between the second busbar component 6 and the third busbar component 7. When corresponding functional elements are arranged in the corresponding isolating points 8 and 9, as in the embodiment according to Figures 1 to 4 As in the embodiment of FIG. 1 , the first bus bar component 5 can be connected to the second bus bar component 6 via the first isolation point 8 , and the second bus bar component 6 can be connected to the third bus bar component 7 via the second isolation point 9 .

[0037] exist Figures 1 to 4 In the design of the connecting terminal 1 shown in FIG. 1 , the two functional elements are respectively configured as isolating blades 10, which are arranged in a swiveling manner in the terminal housing 2. If the two isolating blades 10 are in Figure 1 and 4 In the first position shown in FIG. 1 , the first busbar component 5 is conductively connected to the second busbar component 6 via the first isolating blade 10, and the second busbar component 6 is conductively connected to the third busbar component 7 via the second isolating blade 10. On the contrary, if one of the two isolating blades 10 ( Figure 2 ) or two isolation knives 10 ( Figure 3 ) is in its second position, then the busbar parts 5 and 6 or 6 and 7 corresponding to the respective isolation points 8, 9 are not connected to each other but are separated from each other.

[0038] Figure 5 and 6 A variant of the connection terminal 1 is shown, wherein an isolating plug 11 is inserted into the first isolating point 8 as a functional element ( Figure 5 ), and the component plug 12 serves as a functional element ( Figure 6 ) is arranged in the second isolation point 9. Figure 1 and Figure 5 and 6As can be seen from the comparison, the connection terminals 1 shown in the figure are all of the same construction. The isolation points 8, 9 are respectively constructed so that they can selectively accommodate an isolation blade 10 pivotably supported in the terminal housing 2, or a pluggable functional element such as an isolation plug 11 or a component plug 12. Figure 5 and 6 The component plug 12 shown in the figure can also be inserted into a fuse plug, for example, in one or both isolation points 8, 9. By inserting the component plug 12 or the fuse plug, the connection terminal 1 can be simply converted into a corresponding functional terminal. If the isolation blade 10 is arranged in a pivotable manner in the terminal housing 2, the circuits on the various conductor connections 3, 4 can be opened and closed independently of each other, quickly and simply.

[0039] In the terminal block 1 shown in the figures, two functional shafts 13 are arranged centrally in the terminal housing 2, i.e. between the two isolating points 8, 9, and correspondingly two connection possibilities 14 are formed in the second busbar part 6 in the form of openings for inserting corresponding functional elements. The functional shaft 13 between the two isolating points 8, 9 serves to accommodate the plug contacts of the bridging elements 15, 16, via which the voltage potential fed in can be distributed to the terminal blocks arranged adjacent to each other (see Figure 8 ). The functional shaft 13 arranged between the two isolation points 8 and 9 can therefore also be called a bridge shaft.

[0040] In addition, two functional shafts 17, 20 are also arranged in the terminal housing 2 between the first conductor connection 3 and the first isolation point 8 and between the second conductor connection terminal 4 and the second isolation point 9. For the two functional shafts 17 arranged adjacent to the first conductor connection 3, corresponding connection possibilities 18 are constructed in the first busbar part 5. Correspondingly, for the two functional shafts 20 arranged adjacent to the second conductor connection 4, corresponding connection possibilities 21 are also constructed in the third busbar part 7. The connection possibilities constructed in the individual busbar parts 5, 6, 7 are respectively constructed as rectangular openings in the busbar part, into which the plug contacts of the corresponding functional element can be inserted. Here, as functional elements, for example, a bridging element 16, a test socket 19, a test plug or a test plug can be used.

[0041] Figure 2 and Figure 3 A detection socket 19 ( Figure 2 ) or with two inserted detection sockets 19 ( Figure 3 ) of the connecting terminal 1. Here, the isolating knife 10 adjacent to the corresponding inserted test plug 19 is located in its disconnected position, so that the corresponding circuit test can be performed through the test socket 19.

[0042] exist Figures 1 to 6 In the connecting terminal 1 shown in FIG. 1 , the two conductor connection parts 3 and 4 each have a conductor connection element configured as a spring force clamping joint. For this purpose, a clamping spring 22 is arranged in a corresponding recess in the terminal housing 2, and its clamping legs 23 together with the busbar 24 form a clamping location for the conductor to be connected. The busbar 24 of the two spring force clamping joints is formed by the end of the first busbar part 5 facing the first conductor connection part 3 or by the end of the third busbar part 7 facing the second conductor connection part 4. The busbar 24 of the spring force clamping joint is therefore part of the first busbar part 5 or part of the third busbar part 7.

[0043] Each conductor connection element can be configured as a screw terminal, a tension spring terminal or a cutting connection terminal. By means of the correspondingly configured conductor connection element, the end of the electrical conductor is electrically connected to the first busbar part 5 or the third busbar part 7 and thus the conductor is connected to the connection terminal 1.

[0044] As an alternative thereto, the two conductor connections 3, 4 can also be designed as plug-in locations 25, into which corresponding connection plugs 26 can be plugged, as in Fig.11 and 12 Here, the plug-in location 25 is formed directly by the end of the first busbar part 5 or the third busbar part 7 facing the first conductor connection part 3 or the second conductor connection part 4, just like the busbar in the conductor connection element, and is currently configured as a plug pin.

[0045] from Figure 1 and especially from the basis Figure 4 As can be seen from the cross-sectional view of , the three busbar parts 5, 6, 7 are each constructed in a U shape and have a connecting section extending in the longitudinal direction L of the connecting terminal 1 and two contact sections bent out from the connecting section. Here, the contact section is either a part of the conductor connection elements 3, 4 or a part of the isolation points 8, 9. In addition, it can be seen from the figure that the first busbar part 5 and the third busbar part 7 are constructed identically and are arranged in a mirror-symmetrical manner to each other in the terminal housing 2. Therefore, the same components can be used for the first busbar part 5 and the third busbar part 7, which simplifies the manufacture of the connecting terminal 1.

[0046] exist Figure 4 The connection terminal 1 shown in Figure 1 The connection terminal 1 shown in FIG. 1 differs in that a different type of spring force clamping connection is provided therein. Figure 1 The terminal blocks 1 and Figure 4 In the terminal block 1 shown in FIG. 1 , the conductor connection element has a clamping spring 22 with a clamping leg 23 and a busbar 24. However, in the embodiment according to Figure 4 In the spring force clamping joint realized in the terminal 1 of FIG. 1 , the clamping spring 22 is in a pre-tensioned state, so that the clamping part is opened. In this type of spring force clamping joint, the conductor to be connected can be easily introduced into the clamping part through the conductor introduction opening 27 in the terminal housing 2. Then, the end of the inserted conductor presses against the slider 28 which is arranged pivotably in the terminal housing 2, thereby moving the operating button 29 from its position. Figure 4 The deflected position of the clamping legs 23 shown in FIG. 2 is unlocked, so that the clamping legs 23 spring back and clamp the inserted conductor against the busbar 24 .

[0047] If the clamping point is to be opened again, for example to pull a connected conductor out of the terminal 1, then the two terminals 1 ( Figure 1 and Figure 4 ) must be pressed into the interior of the terminal housing 2, whereby the clamping legs 23 are deflected and lifted from the connected conductor.

[0048] Figures 7 to 12 Different embodiments of a terminal block 30 with a plurality of terminal blocks 1 arranged next to one another are shown. Figures 7 to 10 The terminal block 30 shown in FIG. 1 also has a feed terminal 31 for connecting a potential in addition to the connection terminal 1. The feed terminal 31 has a terminal housing 32 in which two conductor connections 33, 34 are arranged, which are electrically connected to each other via a through busbar.

[0049] In the embodiment of the feed terminal 31 shown in the drawings, the two conductor connections 33, 34 each have a conductor connection element configured as a spring force clamping joint. In addition, two functional shafts 35 are configured in the terminal housing 32 of the feed terminal 31, which are arranged between the two conductor connections 33, 34. Corresponding to the two functional shafts 35, a connection possibility in the form of an opening is configured in the busbar of the feed terminal 32, into which the plugs of the bridging elements 15, 16 can be inserted respectively. Thus, each terminal 1 can be connected to a potential via the bridging elements 15, 16 inserted into the functional shaft 13 of the terminal or into the functional shaft 35 of the feed terminal 31, which potential is connected to the feed terminal 31 via the conductor connections 33, 34.

[0050] according to Fig. 9 and Fig.10 It can be seen again that by constructing additional functional shafts 17, 20 in the individual connecting terminals 1, additional functional elements, such as further bridging elements 16 or test sockets 19, can be inserted and connected to the connecting terminals 1 or busbar parts 5, 7, so that the individual current paths can be tested or the potentials present at the individual connecting terminals 1 can be bridged.

[0051] Fig.11 and 12 The figure shows a terminal block 30, which is composed of a plurality of terminals 1 which are locked side by side on a support rail 36. The conductor connection parts 3, 4 of each terminal 1 have a plug-in position 25, so that a corresponding connection plug 26 can be plugged into the plug-in position 25, as shown in FIG. Fig.12 Here, the conductor to be connected to the connecting terminal 1 is connected to the corresponding conductor connection element of the connecting plug 26.
