Definitions
- the invention relates to a busbar crocodile clip, as it is from DE 20 2011 000 622 U1 and the DE 10 2012 203 554 A is known, that is, a connection device for contacting a busbar, referred to below for short as a busbar, usually a copper bar or a bar made of an otherwise suitable electrically conductive material, in particular with a rectangular or square cross section.
- the busbar crocodile clip creates an electrically conductive contact with the respective busbar.
- the busbar crocodile clip enables the potential made available via the busbar to be tapped, for example in a switch cabinet or the like, and the potential that is supplied centrally can be routed to other locations in the switch cabinet, switch box, etc. via the busbar crocodile clip, for example to electrical ones located there Devices, e.g. fuse holders, automatic circuit breakers, motor protection switches, contactors, sockets and the like, to provide the respective potential.
- One object of the innovation proposed here is to provide a further embodiment of a basically from the DE 20 2011 000 622 U1 or the DE 10 2012 203 554 A known busbar alligator clip.
- a busbar crocodile clip with the features of claim 1.
- the busbar alligator clamp and its clamp body comprise means for electrically conductive contacting of a busbar.
- the busbar alligator clip is on the busbar by means of an extension in its function as a stop comprehensive clamping device fixable.
- this includes means for electrically conductive contact between a conductor brought to the busbar crocodile clip and the clamping body using spring-clamp technology, for example at least one spring-loaded terminal.
- the housing of the busbar crocodile clip for example a housing part, has means for ensuring a defined relative position of at least three components of the busbar crocodile clip. These components are at least the housing of the busbar crocodile clip, the clamping body and the means or means for electrically conductive contacting of a conductor, for example a spring-loaded terminal or several spring-loaded terminals.
- the busbar crocodile clip is fixed to the respective busbar, for example, by means of a clamping screw screwed into the clamping body. Alternatively, this fixation can also be realized by means of a clamping device based on spring force.
- Clamping body holding means act on the one hand in or on the housing and on the other hand in or on the clamping body as a means for ensuring the defined relative position explained above at least of the named components of the busbar crocodile clip.
- recesses in the clamping body and lugs on the housing intended to engage in these recesses come into consideration as clamping body holding means.
- the housing holds, for example, spring-loaded terminals, which are mentioned in the following for better readability, but without waiving further generality instead of means for electrically conductive contacting of a conductor brought up to the busbar crocodile clip, which, however, can still always be read, in a defined position .
- the clamping body is also held in a defined position in relation to the housing by clamping body holding means in the form of recesses and lugs. Overall, this ensures that the spring-loaded terminals, the clamping body and the housing are located in a defined relative position to one another, which enables the function of the busbar crocodile clip.
- a major advantage of the busbar crocodile clip according to the invention is its structure, which is optimized with regard to simple manufacture. This is also evident in a method for producing a busbar crocodile clip of the type described here and below.
- spring-loaded terminals or other actuating means using spring-clamp technology are placed in the interior of the housing in recesses provided for this purpose as means for electrically conductive contact with a conductor brought up to the busbar crocodile clip.
- the clamping body is placed in the inner part of the housing. In the process, the clamping body holding means come into engagement with one another (the clamping body is placed in the housing inner part with the clamping body holding means engaging in one another).
- the clamping body is placed in the inner part of the housing first or in a second step.
- the housing inner part can with the components attached therein / thereon as a whole inserted into the housing outer part and latched there, for example.
- busbar alligator clip can also be developed by means of individual or several method features which enable or promote the execution of the method, and the manufacturing method can also be developed in accordance with one or more device features necessary for executing the method.
- the advantage of the innovation is that the fixation of the busbar alligator clip on the respective busbar can be permanently loaded both electrically and mechanically. Because the clamping body with its hook-shaped extension is a solid component, the clamping screw can be used to fix the busbar alligator clip on the respective busbar, as is known from a screw clamp or the like.
- the fixation on the busbar is therefore extremely mechanically resilient and is also suitable, for example, for environments in which the busbar alligator clip is exposed to particular mechanical stresses, such as vibrations, as often occur during the operation of electrical devices. Because the clamping body with its hook-shaped extension is designed as a solid component, there is a large-area contact at least between that part of the extension that functions as a stop for the clamping device and the busbar.
- Such a large-area mechanical contact also results in reliable electrical contacting of the respective busbar, with the entire surface of the part of the extension acting as a stop and the entire underside of the clamping screw as contact points and thus points for electrical charge transfer available stand.
- a possibility for connecting electrical conductors in spring clip technology is also very mechanically and electrically resilient.
- a connection using clamping spring technology makes contact with a hard vein (wire), for example a copper wire or the like, by means of an effective spring force in a mechanically permanent and electrically safe manner in a retaining profile of a spring mechanism.
- the mechanical and electrical connection is based on self-locking of the respective spring mechanism and, if necessary, the wire can be easily released by actuating the respective spring mechanism accordingly.
- connection point made using spring clip technology is characterized by a connection that can be established quickly and easily while at the same time being easy to detach.
- a connection point in particular a connection point of this type implemented in the form of a spring-loaded terminal, avoids sources of error, such as those that can arise in classic screw connections due to the development of heat or vibrations.
- spring-loaded terminals act as means for electrically conductive contacting of a conductor, which have a leg fixed in the housing or by means of the housing and a movable leg, with a free end of each fixed leg engaging the recess in the clamping body.
- the spring-loaded terminals are thus also connected to the clamping body (at least mechanically) and the clamping body holding means, for example in the form of the recesses in the Clamping bodies also directly ensure a defined position of the clamping body relative to the spring-loaded terminals.
- the overall result is that the spring-loaded terminals, the clamping body and the housing are in a defined position relative to one another, which enables the busbar crocodile clip to function.
- the clamping body for electrically conductive contacting of a conductor comprises lateral contact surfaces and on their surfaces at least one notch means, for example a notch means in the form of at least one rib running transversely to the longitudinal axis of an inserted conductor end.
- a notch means or means ensure an increase in the holding force acting on a conductor connected to the busbar crocodile clip.
- the clamping body is a solid, one-piece component with at least one clamping screw threaded hole
- the clamping device comprising at least one clamping screw guided in the clamping screw threaded hole and wherein the busbar alligator clip can be fixed to the busbar by means of the clamping screw by the busbar is clamped by means of the clamping screw and the part of the extension acting as a stop.
- the clamping body can be produced in one operation and the extension is mechanically sufficiently firmly connected to the clamping body to prevent the when a busbar is clamped, in particular when clamping a busbar between a clamping screw and the clamping body extension to be able to absorb forces that occur.
- the clamping device for fixing the busbar crocodile clip to the busbar is independent of one or more spring-loaded terminals, conductors can be connected to the busbar crocodile clip or detached from it without loosening the fixation of the busbar crocodile clip to the busbar and vice versa.
- a solution for fixing the busbar crocodile clip from the busbar comes e.g. then into consideration if their position on the busbar is to be changed, for example to attach more busbar alligator clips to the busbar. For such a situation, too, it is advantageous if electrical conductors that may already be connected to the busbar crocodile clip do not have to be released and have to be reconnected later.
- the housing is an at least two-part housing with an inner housing part and an outer housing part that accommodates the inner housing part, and that the housing-side clamping body holding means, i.e., for example, the lugs engaging the recesses in the clamping body, are part of the housing inner part are.
- the spring-loaded terminals and the clamping body can be attached to the housing inner part, the housing inner part ensuring the defined relative position between the housing inner part, the clamping body and the spring-loaded terminals, and the resulting combination can be introduced as a whole into the housing outer part, whereby the Insertion into the outer part of the housing completes the production of the busbar crocodile clip.
- the outer part of the housing fixes the spring-loaded terminals placed in the inner part of the housing and the clamping body in their relative position provided for the function of the busbar crocodile clip.
- the housing inner part and the housing outer part are optionally detachably connected to one another, for example by locking. Overall, a tool-free and easily automatable production of the busbar crocodile clip is thus possible.
- a recess determined by the geometry of the hook-shaped extension between the part of the extension that functions as a stop and an underside of the other clamping body, in particular in the area of a screw threaded hole is a combination of the busbar crocodile clip with busbars of different thicknesses and width allowed.
- a maximum thickness of busbars, on which a busbar crocodile clip of the type described here and below can be fixed, is a thickness that corresponds to a clear distance between the part of the extension acting as a stop and an opposite underside of the other clamping body, in particular the area with the clamping screw threaded bore , corresponds.
- the busbar crocodile clip can be combined with busbars of lesser thickness, for example by screwing a clamping screw into the thread formed in the clamping screw threaded bore until it makes contact with an upper side of the busbar.
- a minimum thickness of a busbar on which a busbar crocodile clip of the type described here and below can be fixed is a thickness that results from a clear width of the type described above minus a free length of the thread of the clamping screw. Theoretically, the free thread of the clamping screw extends even without a busbar inserted into the recess formed by the extension to the part of the extension that functions as a stop, so that even very thin busbars can be reliably contacted.
- busbars have a minimum thickness determined by static considerations, which can be achieved even without the busbar, e.g. to bend or the like a fixation of one or more busbar crocodile clips allowed. Based on this premise, the busbar crocodile clip can be securely connected to busbars of any thickness below the maximum thickness described above.
- the housing also encloses the hook-shaped extension apart from the recess for combining with the busbar, the current-carrying parts are protected as much as possible.
- the extension with the housing section formed there can be incorporated into the design in this way the busbar alligator clip must be included as a whole, so that the result is an attractive appearance.
- the contact protection can be improved even further if the busbar is equipped with covers, e.g. cover caps, which are combined with the busbar adjacent to the busbar crocodile clip, e.g. by sliding on, snapping on, etc.
- busbar alligator clip with its housing covers a surface of the busbar when it is attached to a busbar, effective protection against contact is also achieved.
- Operating personnel e.g. slips off when connecting or disconnecting electrical conductors from a busbar crocodile clip with a screwdriver, cannot come into contact with the area of the surface of the busbar covered by the housing of the busbar crocodile clip, so that a risk for operating personnel is reduced.
- the busbars are also equipped with appropriate cover caps, the power distribution can be made almost fingertip safe.
- a clamping screw or the like intended for fixing the busbar alligator clip to the busbar is reset by actuating elements provided in the area of the upper part of the housing for fixing electrical conductors to the busbar alligator clamp, for example spring-loaded clamps
- contact protection is created in a simple manner and also provides a possibility for operating personnel to identify those parts (clamping screw, actuating element, etc.) which are provided for fixing the busbar crocodile clip on the one hand or for connecting electrical conductors to the busbar crocodile clip on the other hand. Incorrect operation is largely ruled out and operating personnel will intuitively use the clamping screw, actuating element, etc. on the top of the busbar crocodile clip correctly.
- FIG. 1 shows an isometric side view of an embodiment of an already known busbar crocodile clip 10 ( DE 20 2011 000 622 U1 , DE 10 2012 203 554 A ).
- the busbar alligator clip is attached to a busbar 12.
- FIG. 13 shows a sectional illustration of the embodiment of the busbar alligator clip 10 according to FIG Fig. 1 .
- the busbar alligator clip 10 has a clamping body 16 in a housing 14, which is characterized by a hook-shaped extension 18.
- the busbar crocodile clip 10 is by means of the extension 18 in its function as a stop Clamping device can be fixed on busbar 12.
- this clamping device further comprises at least one clamping screw 22 guided in a clamping screw threaded bore 20 in the clamping body 16.
- the clamping body 16 is a solid component, for example a brass block, an aluminum block or generally a block made of an electrically conductive metal.
- the busbar crocodile clip 10 has conductor insertion openings 26 on opposite connection sides 24.
- the hook-shaped extension 18 is made in one piece and is connected in one piece to the clamping body 16.
- the clamping body 16 thus forms a shaped metal block with its hook-shaped extension 18.
- the busbar crocodile clip 10 can be fixed to the busbar 12 with the clamping screw 22, in that the busbar 12 is clamped by means of the clamping screw 22 and the part of the extension 18 functioning as a stop.
- the busbar 12 is located in a recess 30 formed by the clamping body 16 and its hook-shaped extension 18 ( Fig. 3 ) and is clamped there with the clamping screw 22 against the hook-shaped extension 18 of the clamping body 16 as in a screw clamp.
- This fixation of the busbar crocodile clip 10 on the busbar 12 produces a mechanically very strong and resilient contact between the busbar crocodile clip 10 and the busbar 12.
- the illustrated embodiment of the busbar alligator clip 10 is used to fix one end of a conductor 32 inserted through a conductor insertion opening 26 into a bore in the clamping body 16 (in Fig. 2 Not shown; please refer Fig. 4 ) shown as actuating element 34 each have a clamping screw.
- FIG. 3 shows an isometric view of an embodiment of the busbar crocodile clip 10 according to the invention.
- This also has a clamping body 16 in a housing ( Fig. 5 ) with a hook-shaped extension 18, by means of which the busbar alligator clip 10 on a busbar 12 ( Fig. 1 , Fig. 2 ) can be fixed to obtain an electrically conductive contact with the busbar 12.
- the preceding explanations on the clamping body 16 and its extension 18 and on the fixing of the busbar crocodile clip 10 on a busbar 12 apply accordingly to the busbar crocodile clip 10 presented for the first time in the description presented here. Due to the geometry of the hook-shaped extension 18 and the resulting width of the recess 30, a combination of the busbar crocodile clip 10 with busbars 12 of different cross-sections is possible.
- the busbar crocodile clip 10 has one or more conductor insertion openings 26 on an upper side 28 facing away from the extension 18 - in the example shown, two conductor insertion openings 26, namely one conductor insertion opening each on both sides of a central axis in the area of the clamping screw 22 26.
- a tool insertion opening 36 belongs to each conductor insertion opening 26. In the exemplary embodiment shown, the tool insertion openings 36 are located, starting from the central axis of the busbar crocodile clip 10, following each conductor insertion opening 26.
- FIG. 4 shows the busbar alligator clip 10 according to Figure 3 with conductors 32 connected to the busbar crocodile clip 10 and inserted into the conductor insertion openings 26.
- the representations in Figure 5 and Figure 6 show the busbar alligator clip 10 according to Figure 3 in a partially sectioned view.
- the representation in Figure 5 shows the busbar alligator clip 10 in an isometric view as in FIG Figure 3 .
- the representation in Figure 6 shows the busbar alligator clip 10 in a side view. To maintain the sectional view, one of the two must be aligned with the vertical axis (sheet level in the illustration in Figure 6 ) the busbar crocodile clip 10 parallel side walls of the housing 14 has been removed.
- the view of the clamping body 16 in the interior of the housing 14 and the actuating elements 34 of the busbar crocodile clip 10 becomes clear.
- the busbar crocodile clip 10 has actuating elements 34 using spring clip technology.
- a spring-loaded terminal 34 acts as the actuating element 34 using spring-clamp technology.
- Spring-loaded terminals 34 are basically known per se and are known to be sometimes also referred to as cage clamps, cage clamps or spring clamps.
- the spring-loaded terminal 34 functions as an actuating element 34 because when a conductor 32 is connected to the busbar crocodile clip 10, its end actuates the spring-loaded terminal 34 and because when a conductor 32 connected to the busbar crocodile clip 10 is loosened, the spring-loaded terminal 34 is opened by means of a tool 38 inserted into a tool insertion opening 36 ( Fig. 8 ) the spring-loaded terminal 34 is actuated to release the end of the conductor.
- the housing 14 is an at least two-part housing 14. This comprises a preferably one-piece housing inner part 40 and an outer housing part 42 accommodating the inner housing part 40.
- a detachable connection can be used to combine the inner housing part 40 with the outer housing part 42.
- Shown as an example of basically any means for releasably fixing the housing inner part 40 in the housing outer part 42 are a latching hook formed on the housing inner part 40 and a corresponding latching hook receptacle formed in the housing outer part 42 for receiving the respective latching hook.
- the housing inner part 40 carries the or each actuating element 34 of the busbar crocodile clip 10 and the clamping body 16.
- a spring-loaded seat contour is formed in the housing inner part 40 for at least some sections of the form-fitting receiving and fixing of a spring-loaded terminal 34.
- the housing inner part 40 in the embodiment shown has two lugs 44 which engage in corresponding recesses 46 in the clamp body 16 (in the illustration in FIG Figure 5 only one nose 44 and only one recess 46 is designated).
- the lugs 44 on the side of the housing inner part 40 and the recesses 46 in the clamping body 16 are examples of clamping body holding means 44, 46.
- a lug 44 functioning as a clamping body holding means 44 can also be part of the clamping body 16 and to engage in a clamping body holding means 46 acting recess 46 in the housing inner part 40 be determined. It is essential that the clamping body 16 is detachably connected to the housing inner part 40 by means of the clamping body holding means 44, 46 and a defined relative position of the housing inner part 40 and the clamping body 16 is ensured by means of the clamping body holding means 44, 46.
- a basically optional configuration is shown in which one of the free ends of the clamping spring / spring-loaded terminal 34 also engages in the recess 46 in the clamping body 16.
- This free end of the spring-loaded terminals 34 connects to one of the illustration ( Fig. 6 ) horizontal Legs of the spring-loaded terminals 34.
- This leg which is horizontal in the illustration, rests on a support surface 48 which is likewise horizontal in the illustration and is formed in the housing inner part 40.
- spring-loaded terminals 34 Since these free ends of the spring-loaded terminals 34 also engage in the recesses 46 in the clamping body 16, they also function as clamping body holding means 44, 46 and guide tensile and / or compressive forces due to the clamping body 16 onto the housing inner part 40, in particular by tensile and / or compressive forces be distributed on the support surface 48 of the housing inner part 40 due to the clamping body 16. This relieves the noses 44 of the housing inner part, especially when metallic spring-loaded terminals 34 are used as spring-loaded terminals.
- FIG. 7a , 7b shows a side view of a further sectional view of the busbar alligator clip 10 according to Figure 3 .
- the cutting plane is in comparison to the cutting plane in Figure 5 and Figure 6 deeper and runs approximately in the middle through the busbar crocodile clip 10.
- a connection space 50 adjoins the conductor insertion openings 26.
- the stripped end of a conductor 32 to be connected to the busbar crocodile clip 10 is led into this area (the illustration in Figure 8 shows a connected conductor 32).
- the stripped end of the conductor 32 is passed through an eyelet in one of the two legs of the spring-loaded terminal 34 in a manner known per se.
- This eyelet is part of the retaining profile of the spring-loaded terminal 34 and is intended for passing the end of the conductor through.
- the eyelet is in the leg that is horizontal in the illustration.
- the conductor end is passed through this and reaches the connection space 50 in the process.
- the connection space 50 the conductor end is pressed by means of the other leg (leg without eyelet) against a side surface of the clamping body 16 functioning as a contact surface 52.
- the clamping body 16 optionally has one or more notch means on its contact surface 52 to improve the holding of a conductor end, for example in the form of the ribs shown (not designated).
- the respective notch means in particular the or each rib, notches the surface of the conductor end with its surface or edge facing the conductor end.
- a similar notch effect is associated with the end of the movable leg of the spring clamp 34. With at least one such rib on the contact surfaces 52 of the clamping body 16, the conductor end is additionally held by notches on both sides.
- clamping screw 22 is shown clearly above the clamping screw threaded bore 20. With a clamping screw 22 screwed into the clamping screw threaded bore 20, the head of the clamping screw 22 is located well below the top 28 of the busbar alligator clip 10, which is defined by the surface of the housing inner part 40. After tightening the clamping screw 22 to fix the busbar alligator clamp 10 on a busbar 12, the head is the clamping screw 22 is set back even further from the top 28.
- the busbar alligator clip 10 can be briefly released from the busbar 12, for example, in order to change a position of the busbar alligator clip 10 on the busbar 12 without having to disconnect any electrical conductors 32 that may already be connected to the busbar crocodile clip 10.
- FIG. 8 shows the sectioned busbar alligator clip 10 according to FIG Figure 7 with conductor ends inserted into the conductor insertion openings 26 and into the connection spaces 50. It can be seen that the conductor ends are pressed against one of the contact surfaces 52 of the clamping body 16 by means of the movable leg of the respective spring-loaded terminal 34 in order to maintain an electrically conductive contact with the clamping body 16. It can also be seen that a conductor 32 connected to the busbar crocodile clip 10 can be released again from the busbar crocodile clip 10 by means of a tool 38, for example the blade of a screwdriver (not shown to scale).
- the movable leg of the respective spring-loaded terminal 34 is deflected further (further than by the conductor end itself) by means of the tool 38, so that the free end of the movable leg of the spring-loaded terminal 34 disengages from the surface of the conductor end.
- the conductor end can then be pulled out of the connection space 50 and the conductor insertion opening 26.
- the representation in Figure 9 shows on the one hand the busbar alligator clip 10 in a representation as in FIG Figure 7 as well as in a sectional view along the cutting line labeled AB.
- the section along the section line AB runs just above the leg of the spring-loaded terminals 34, which is horizontal in the illustration. In the sectional illustration, the view of this is accordingly Legs of the spring-loaded terminals 34 and the eyelet therein and on the connection space 50 connected below are free. The cut, movable leg of the spring-loaded terminals 34 can also be seen.
- FIG. 10 shows, in a schematically simplified manner, snapshots during the manufacture / assembly of a busbar crocodile clip 10. It is shown that in a first step the spring-loaded terminals 34 are first placed in the housing inner part 40, namely each in a clamping spring seat contour provided for this purpose. In a subsequent second step, the clamping body 16 is placed in the housing inner part 40. The lugs 44 of the housing inner part 40 and the recesses 46 in the clamping body - or generally the respective clamping body holding means 44, 46 - come into engagement with one another. A component with three different components, namely the housing inner part 40, the clamping body 16 and the spring-loaded terminals 34, is thus created. The order of steps 1 and 2 can also be reversed for its production.
- This component 40, 16, 34 is combined as a whole with the outer housing part 42 and pushed into the outer housing part 42 for this purpose.
- the housing inner part 40 can be connected to the housing outer part 42 in a latching manner. The production / assembly of the busbar crocodile clip 10 is thus completed without tools.
- a busbar crocodile clip 10 is specified according to FIG DE 20 2011 000 622 U1 or the DE 10 2012 203 554 A with a clamp body 16 that can be fixed to a busbar 12 in the manner of a screw clamp or optionally according to FIG DE 20 2011 000 622 U1 or the DE 10 2012 203 554 A with means 34 for electrically conductive contacting of a conductor 32 brought up to the busbar crocodile clip 10 with the clamping body 16 using spring clip technology, that is to say a busbar crocodile clip 10 using spring clip technology

Description
Die Erfindung betrifft eine Sammelschienenabgreifklemme, wie sie aus der
Eine Aufgabe der hier vorgeschlagenen Neuerung besteht darin, eine weitere Ausführungsform einer grundsätzlich aus der
Diese Aufgabe wird erfindungsgemäß mittels einer Sammelschienenabgreifklemme mit den Merkmalen des Anspruchs 1 gelöst. Dazu ist bei einer Sammelschienenabgreifklemme mit einem in einem Gehäuse angeordneten Klemmkörper mit einem vom Klemmkörper umfassten hakenförmigen Fortsatz Folgendes vorgesehen: Die Sammelschienenabgreifklemme sowie deren Klemmkörper umfassen Mittel zum elektrisch leitenden Kontaktieren einer Sammelschiene. Die Sammelschienenabgreifklemme ist an der Sammelschiene mittels einer den Fortsatz in seiner Funktion als Anschlag umfassenden Klemmvorrichtung fixierbar. Zum Anschluss elektrischer Leiter an die Sammelschienenabgreifklemme umfasst diese Mittel zum elektrisch leitenden Kontaktieren eines an die Sammelschienenabgreifklemme herangeführten Leiters mit dem Klemmkörper in Klemmfedertechnik, zum Beispiel zumindest eine Federkraftklemme. Das Gehäuse der Sammelschienenabgreifklemme, zum Beispiel ein Gehäuseteil, weist Mittel zur Gewährleistung einer definierten Relativposition von zumindest drei Komponenten der Sammelschienenabgreifklemme auf. Bei diesen Komponenten handelt es sich zumindest um das Gehäuse der Sammelschienenabgreifklemme, den Klemmkörper sowie das oder die Mittel zum elektrisch leitenden Kontaktieren eines Leiters, also zum Beispiel eine Federkraftklemme oder mehrere Federkraftklemmen. Die Fixierung der Sammelschienenabgreifklemme an der jeweiligen Sammelschiene erfolgt zum Beispiel mittels einer in den Klemmkörper eingeschraubten Klemmschraube. Alternativ kann diese Fixierung ebenfalls mittels einer auf Federkraft basierenden Klemmvorrichtung realisiert sein.According to the invention, this object is achieved by means of a busbar crocodile clip with the features of
Als Mittel zur Gewährleistung der oben erläuterten definierten Relativposition zumindest der genannten Komponenten der Sammelschienenabgreifklemme fungieren Klemmkörperhaltemittel einerseits im oder am Gehäuse und andererseits im oder am Klemmkörper. Als Klemmkörperhaltemittel kommen zum Beispiel Ausnehmungen im Klemmkörper sowie zum Eingriff in diese Ausnehmungen bestimmte Nasen am Gehäuse in Betracht. Das Gehäuse hält zum Beispiel Federkraftklemmen, die im Folgenden zur besseren Lesbarkeit, aber ohne Verzicht auf eine weitergehende Allgemeingültigkeit anstelle von Mitteln zum elektrisch leitenden Kontaktieren eines an die Sammelschienenabgreifklemme herangeführten Leiters genannt sind, welche aber nach wie vor stets mitzulesen sind, in einer definierten Position. Durch Klemmkörperhaltemittel in Form von Ausnehmungen und Nasen wird auch der Klemmkörper in Relation zum Gehäuse in einer definierten Position gehalten. Damit ist insgesamt sichergestellt, dass die Federkraftklemmen, der Klemmkörper und das Gehäuse sich in einer definierten, die Funktion der Sammelschienenabgreifklemme ermöglichenden Relativposition zueinander befinden.Clamping body holding means act on the one hand in or on the housing and on the other hand in or on the clamping body as a means for ensuring the defined relative position explained above at least of the named components of the busbar crocodile clip. For example, recesses in the clamping body and lugs on the housing intended to engage in these recesses come into consideration as clamping body holding means. The housing holds, for example, spring-loaded terminals, which are mentioned in the following for better readability, but without waiving further generality instead of means for electrically conductive contacting of a conductor brought up to the busbar crocodile clip, which, however, can still always be read, in a defined position . The clamping body is also held in a defined position in relation to the housing by clamping body holding means in the form of recesses and lugs. Overall, this ensures that the spring-loaded terminals, the clamping body and the housing are located in a defined relative position to one another, which enables the function of the busbar crocodile clip.
Ein wesentlicher Vorteil der erfindungsgemäßen Sammelschienenabgreifklemme besteht in ihrem im Hinblick auf eine einfache Herstellung optimierten Aufbau. Dies zeichnet sich auch in einem Verfahren zur Herstellung einer Sammelschienenabgreifklemme der hier und im Folgenden beschriebenen Art ab. Bei einem solchem Verfahren ist Folgendes vorgesehen: Es werden als Mittel zum elektrisch leitenden Kontaktieren eines an die Sammelschienenabgreifklemme herangeführten Leiters fungierende Federkraftklemmen oder sonstige Betätigungsmittel in Klemmfedertechnik im Gehäuseinnenteil in dafür vorgesehenen Ausnehmungen platziert. Des Weiteren wird der Klemmkörper im Gehäuseinnenteil platziert. Dabei kommen die Klemmkörperhaltemittel miteinander in Eingriff (der Klemmkörper wird unter Eingriff der Klemmkörperhaltemittel ineinander im Gehäuseinnenteil platziert). Grundsätzlich kommt es dabei nicht darauf an, ob der Klemmkörper zuerst oder erst in einem zweiten Schritt im Gehäuseinnenteil platziert wird. Nachdem der Klemmkörper und die Betätigungsmittel/Federkraftklemmen im Gehäuseinnenteil platziert sind und durch das Gehäuseinnenteil in einer definierten Relativposition zueinander und zum Gehäuseinnenteil selbst gehalten werden, kann das Gehäuseinnenteil mit den darin/daran angebrachten Komponenten insgesamt in das Gehäuseaußenteil eingeführt und dort zum Beispiel verrastet werden.A major advantage of the busbar crocodile clip according to the invention is its structure, which is optimized with regard to simple manufacture. This is also evident in a method for producing a busbar crocodile clip of the type described here and below. In such a method, the following is provided: spring-loaded terminals or other actuating means using spring-clamp technology are placed in the interior of the housing in recesses provided for this purpose as means for electrically conductive contact with a conductor brought up to the busbar crocodile clip. Furthermore, the clamping body is placed in the inner part of the housing. In the process, the clamping body holding means come into engagement with one another (the clamping body is placed in the housing inner part with the clamping body holding means engaging in one another). In principle, it does not matter whether the clamping body is placed in the inner part of the housing first or in a second step. After the clamping body and the actuating means / spring-loaded terminals are placed in the housing inner part and are held by the housing inner part in a defined position relative to one another and to the housing inner part itself, the housing inner part can with the components attached therein / thereon as a whole inserted into the housing outer part and latched there, for example.
Für die weitere Beschreibung gilt zur Vermeidung unnötiger Wiederholungen, dass Merkmale und Details, die im Zusammenhang mit dem genannten Verfahren zur Herstellung einer Sammelschienenabgreifklemme sowie eventueller Ausgestaltungen beschrieben sind, selbstverständlich auch im Zusammenhang mit und im Hinblick auf die gegenständliche Sammelschienenabgreifklemme und umgekehrt gelten, so dass die Sammelschienenabgreifklemme auch mittels einzelner oder mehrerer Verfahrensmerkmale fortgebildet sein kann, welche die Ausführung des Verfahrens ermöglichen oder befördern, und das Herstellungsverfahren ebenso entsprechend einzelner oder mehrerer zur Ausführung des Verfahrens notwendiger Vorrichtungsmerkmale fortgebildet sein kann.For the further description, in order to avoid unnecessary repetition, features and details that are described in connection with the above-mentioned method for producing a busbar alligator clip as well as possible configurations naturally also apply in connection with and with regard to the busbar alligator clamp in question and vice versa, so that the busbar alligator clip can also be developed by means of individual or several method features which enable or promote the execution of the method, and the manufacturing method can also be developed in accordance with one or more device features necessary for executing the method.
Der Vorteil der Neuerung besteht auch darin, dass die Fixierung der Sammelschienenabgreifklemme an der jeweiligen Sammelschiene sowohl elektrisch wie auch mechanisch dauerhaft belastbar ist. Dadurch, dass der Klemmkörper mit seinem hakenförmigen Fortsatz ein massives Bauteil ist, lässt sich mit der Klemmschraube eine Fixierung der Sammelschienenabgreifklemme an der jeweiligen Sammelschiene erreichen, wie sie von einer Schraubzwinge oder dergleichen bekannt ist. Die Fixierung an der Sammelschiene ist damit mechanisch außerordentlich belastbar und eignet sich z.B. auch für Umgebungen, in denen die Sammelschienenabgreifklemme besonderen mechanischen Beanspruchungen ausgesetzt ist, z.B. Vibrationen, wie sie sich häufig im Betrieb elektrischer Geräte ergeben. Dadurch, dass der Klemmkörper mit seinem hakenförmigen Fortsatz als massives Bauteil ausgeführt ist, ergibt sich ein großflächiger Kontakt zumindest zwischen demjenigen Teil des Fortsatzes, der als Anschlag für die Klemmvorrichtung fungiert, und der Sammelschiene. Durch einen solchen großflächigen mechanischen Kontakt ergibt sich auch eine sichere elektrische Kontaktierung der jeweiligen Sammelschiene, wobei die komplette mit der Sammelschiene in Kontakt stehende Oberfläche des als Anschlag fungierenden Teils des Fortsatzes sowie die komplette Unterseite der Klemmschraube als Kontaktstellen und damit Stellen zur elektrischen Ladungsübertragung zur Verfügung stehen. Eine Möglichkeit zum Anschluss elektrischer Leiter in Klemmfedertechnik ist ebenfalls mechanisch und elektrisch sehr belastbar. Eine Verbindung in Klemmfedertechnik kontaktiert bekanntlich eine Hartader (Draht), zum Beispiel einen Kupferdraht oder dergleichen, mittels einer jeweils wirksamen Federkraft mechanisch dauerhaft und elektrisch sicher in einem Halteprofil eines Federmechanismus. Die mechanische und elektrische Verbindung beruht auf einer Selbsthemmung des jeweiligen Federmechanismus und im Bedarfsfall ist der Draht durch eine entsprechende Betätigung des jeweiligen Federmechanismus einfach lösbar. Eine in Klemmfedertechnik ausgeführte Anschlussstelle zeichnet sich durch eine schnell und einfach herstellbare Verbindung bei gleichzeitiger einfacher Lösbarkeit aus. Eine solche Anschlussstelle, insbesondere eine in Form einer Federkraftklemme realisierte derartige Anschlussstelle, vermeidet Fehlerquellen, wie sie sich bei klassischen Schraubverbindungen mitunter aufgrund von Wärmeentwicklungoder Vibrationen ergeben können.The advantage of the innovation is that the fixation of the busbar alligator clip on the respective busbar can be permanently loaded both electrically and mechanically. Because the clamping body with its hook-shaped extension is a solid component, the clamping screw can be used to fix the busbar alligator clip on the respective busbar, as is known from a screw clamp or the like. The fixation on the busbar is therefore extremely mechanically resilient and is also suitable, for example, for environments in which the busbar alligator clip is exposed to particular mechanical stresses, such as vibrations, as often occur during the operation of electrical devices. Because the clamping body with its hook-shaped extension is designed as a solid component, there is a large-area contact at least between that part of the extension that functions as a stop for the clamping device and the busbar. Such a large-area mechanical contact also results in reliable electrical contacting of the respective busbar, with the entire surface of the part of the extension acting as a stop and the entire underside of the clamping screw as contact points and thus points for electrical charge transfer available stand. A possibility for connecting electrical conductors in spring clip technology is also very mechanically and electrically resilient. As is known, a connection using clamping spring technology makes contact with a hard vein (wire), for example a copper wire or the like, by means of an effective spring force in a mechanically permanent and electrically safe manner in a retaining profile of a spring mechanism. The mechanical and electrical connection is based on self-locking of the respective spring mechanism and, if necessary, the wire can be easily released by actuating the respective spring mechanism accordingly. A connection point made using spring clip technology is characterized by a connection that can be established quickly and easily while at the same time being easy to detach. Such a connection point, in particular a connection point of this type implemented in the form of a spring-loaded terminal, avoids sources of error, such as those that can arise in classic screw connections due to the development of heat or vibrations.

Dabei verwendete Rückbeziehungen weisen auf die weitere Ausbildung der Sammelschienenabgreifklemme durch die Merkmale des jeweiligen Unteranspruches hin.

They are not to be understood as a waiver of the achievement of an independent, objective protection for the features of the subclaims, regardless of any reference. Furthermore, with regard to an interpretation of the claims and the description in a more detailed specification of a feature in a subordinate claim, it can be assumed that such a restriction does not exist in the respective preceding claims and in a more general embodiment of the busbar crocodile clip.

Da die Gegenstände der Unteransprüche im Hinblick auf den Stand der Technik am Prioritätstag eigene und unabhängige Erfindungen bilden können, behält die Anmelderin sich vor, sie zum Gegenstand unabhängiger Ansprüche oder Teilungserklärungen zu machen. Sie können weiterhin auch selbständige Erfindungen enthalten, die eine von den Gegenständen der vorhergehenden Unteransprüche unabhängige Gestaltung aufweisen.Since the subjects of the subclaims with regard to the state of the art can form their own and independent inventions on the priority date, the applicant reserves the right to make them the subject of independent claims or declarations of division. They can also contain independent inventions which have a design that is independent of the subject matter of the preceding subclaims.
Bei einer besonderen Ausführungsform der Sammelschienenabgreifklemme fungieren als Mittel zum elektrisch leitenden Kontaktieren eines Leiters Federkraftklemmen, welche einen im Gehäuse oder mittels des Gehäuses fixierten Schenkel sowie einen beweglichen Schenkel aufweisen, wobei ein freies Ende jedes fixierten Schenkels in die Ausnehmung im Klemmkörper eingreift. Damit sind auch die Federkraftklemmen mit dem Klemmkörper (zumindest mechanisch) verbunden und die Klemmkörperhaltemittel, zum Beispiel in Form der Ausnehmungen im Klemmkörper, gewährleisten unmittelbar auch eine definierte Relativposition des Klemmkörpers zu den Federkraftklemmen. Durch die Halterung des Klemmkörpers und der Federkraftklemmen durch das Gehäuse ergibt sich insgesamt, dass sich die Federkraftklemmen, der Klemmkörper und das Gehäuse in einer definierten, die Funktion der Sammelschienenabgreifklemme ermöglichenden Relativposition zueinander befinden.In a particular embodiment of the busbar crocodile clip, spring-loaded terminals act as means for electrically conductive contacting of a conductor, which have a leg fixed in the housing or by means of the housing and a movable leg, with a free end of each fixed leg engaging the recess in the clamping body. The spring-loaded terminals are thus also connected to the clamping body (at least mechanically) and the clamping body holding means, for example in the form of the recesses in the Clamping bodies also directly ensure a defined position of the clamping body relative to the spring-loaded terminals. As a result of the holding of the clamping body and the spring-loaded terminals by the housing, the overall result is that the spring-loaded terminals, the clamping body and the housing are in a defined position relative to one another, which enables the busbar crocodile clip to function.
Bei einer weiteren besonderen Ausführungsform der Sammelschienenabgreifklemme umfasst der Klemmkörper zum elektrisch leitenden Kontaktieren eines Leiters seitliche Kontaktflächen und auf deren Oberflächen jeweils zumindest ein Kerbmittel, zum Beispiel ein Kerbmittel in Form zumindest einer quer zur Längsachse eines eingeführten Leiterendes verlaufenden Rippe. Ein solches Kerbmittel oder solche Kerbmittel gewährleisten eine Erhöhung der auf einen an die Sammelschienenabgreifklemme angeschlossenen Leiter wirkenden Haltekraft.In a further special embodiment of the busbar alligator clip, the clamping body for electrically conductive contacting of a conductor comprises lateral contact surfaces and on their surfaces at least one notch means, for example a notch means in the form of at least one rib running transversely to the longitudinal axis of an inserted conductor end. Such a notch means or means ensure an increase in the holding force acting on a conductor connected to the busbar crocodile clip.
Bei einer weiteren Ausführungsform der Sammelschienenabgreifklemme ist vorgesehen, dass der Klemmkörper ein massives, einstückiges Bauteil mit zumindest einer Klemmschraubengewindebohrung ist, wobei die Klemmvorrichtung zumindest eine in der Klemmschraubengewindebohrung geführte Klemmschraube umfasst und wobei mittels der Klemmschraube die Sammelschienenabgreifklemme an der Sammelschiene fixierbar ist, indem die Sammelschiene mittels der Klemmschraube sowie dem als Anschlag fungierenden Teil des Fortsatzes eingespannt wird.In a further embodiment of the busbar alligator clip, it is provided that the clamping body is a solid, one-piece component with at least one clamping screw threaded hole, the clamping device comprising at least one clamping screw guided in the clamping screw threaded hole and wherein the busbar alligator clip can be fixed to the busbar by means of the clamping screw by the busbar is clamped by means of the clamping screw and the part of the extension acting as a stop.
Wenn der hakenförmige Fortsatz im Bereich seiner hakenförmigen Kontur einstückig ist und auch mit dem Klemmkörper einstückig verbunden ist, kann der Klemmkörper in einem Arbeitsgang hergestellt werden und der Fortsatz ist mit dem Klemmkörper mechanisch ausreichend fest verbunden, um die beim Einspannen einer Sammelschiene, insbesondere beim Einspannen einer Sammelschiene zwischen einer Klemmschraube und dem Klemmkörperfortsatz, auftretenden Kräfte aufnehmen zu können.If the hook-shaped extension is in one piece in the area of its hook-shaped contour and is also integrally connected to the clamping body, the clamping body can be produced in one operation and the extension is mechanically sufficiently firmly connected to the clamping body to prevent the when a busbar is clamped, in particular when clamping a busbar between a clamping screw and the clamping body extension to be able to absorb forces that occur.
Wenn die Klemmvorrichtung zum Fixieren der Sammelschienenabgreifklemme an der Sammelschiene unabhängig von einer oder mehreren Federkraftklemmen ist, lassen sich Leiter mit der Sammelschienenabgreifklemme verbinden oder von dieser lösen, ohne die Fixierung der Sammelschienenabgreifklemme mit der Sammelschiene zu lösen und umgekehrt. Eine Lösung der Fixierung der Sammelschienenabgreifklemme von der Sammelschiene kommt z.B. dann in Betracht, wenn deren Position an der Sammelschiene verändert werden soll, um zum Beispiel weitere Sammelschienenabgreifklemmen an der Sammelschiene anzubringen. Auch für eine solche Situation ist es vorteilhaft, wenn dann mit der Sammelschienenabgreifklemme eventuell bereits verbundene elektrische Leiter nicht gelöst und später wieder neu verbunden werden müssen.If the clamping device for fixing the busbar crocodile clip to the busbar is independent of one or more spring-loaded terminals, conductors can be connected to the busbar crocodile clip or detached from it without loosening the fixation of the busbar crocodile clip to the busbar and vice versa. A solution for fixing the busbar crocodile clip from the busbar comes e.g. then into consideration if their position on the busbar is to be changed, for example to attach more busbar alligator clips to the busbar. For such a situation, too, it is advantageous if electrical conductors that may already be connected to the busbar crocodile clip do not have to be released and have to be reconnected later.
Bei einer nochmals weiteren, bevorzugten Ausführungsform der Sammelschienenabgreifklemme ist vorgesehen, dass das Gehäuse ein zumindest zweiteiliges Gehäuse mit einem Gehäuseinnenteil und einem das Gehäuseinnenteil aufnehmenden Gehäuseaußenteil ist und dass die gehäuseseitigen Klemmkörperhaltemittel, also zum Beispiel die in die Ausnehmungen im Klemmkörper eingreifenden Nasen, Teil des Gehäuseinnenteils sind. Bei einer solchen Ausführungsform der Sammelschienenabgreifklemme können die Federkraftklemmen und der Klemmkörper am Gehäuseinnenteil angebracht werden, wobei das Gehäuseinnenteil die definierte Relativposition zwischen dem Gehäuseinnenteil, dem Klemmkörper und der Federkraftklemmen gewährleistet, und die sich ergebende Kombination kann insgesamt in das Gehäuseaußenteil eingeführt werden, wobei durch das Einführen in das Gehäuseaußenteil die Herstellung der Sammelschienenabgreifklemme abgeschlossen ist. Das Gehäuseaußenteil fixiert dabei die im Gehäuseinnenteil platzierten Federkraftklemmen und den Klemmkörper in deren zur Funktion der Sammelschienenabgreifklemme vorgesehenen Relativposition. Das Gehäuseinnenteil und das Gehäuseaußenteil sind optional lösbar miteinander verbunden, zum Beispiel durch Verrasten. Insgesamt ist damit eine werkzeuglose und gut automatisierbare Herstellung der Sammelschienenabgreifklemme möglich.In yet another preferred embodiment of the busbar crocodile clip, it is provided that the housing is an at least two-part housing with an inner housing part and an outer housing part that accommodates the inner housing part, and that the housing-side clamping body holding means, i.e., for example, the lugs engaging the recesses in the clamping body, are part of the housing inner part are. In such an embodiment of the busbar crocodile clip, the spring-loaded terminals and the clamping body can be attached to the housing inner part, the housing inner part ensuring the defined relative position between the housing inner part, the clamping body and the spring-loaded terminals, and the resulting combination can be introduced as a whole into the housing outer part, whereby the Insertion into the outer part of the housing completes the production of the busbar crocodile clip. The outer part of the housing fixes the spring-loaded terminals placed in the inner part of the housing and the clamping body in their relative position provided for the function of the busbar crocodile clip. The housing inner part and the housing outer part are optionally detachably connected to one another, for example by locking. Overall, a tool-free and easily automatable production of the busbar crocodile clip is thus possible.
Für weitere Ausführungsformen der Sammelschienenabgreifklemme ist vorgesehen, dass eine durch eine Geometrie des hakenförmigen Fortsatzes bestimmte Ausnehmung zwischen dem Teil des Fortsatzes, der als Anschlag fungiert, und einer Unterseite des sonstigen Klemmkörpers, insbesondere im Bereich einer Klemmschraubengewindebohrung, eine Kombination der Sammelschienenabgreifklemme mit Sammelschienen unterschiedlicher Stärke und Breite erlaubt. Eine maximale Stärke von Sammelschienen, an denen eine Sammelschienenabgreifklemme der hier und nachfolgend beschriebenen Art fixierbar ist, ist eine Stärke, wie sie einem lichten Abstand zwischen dem als Anschlag fungierenden Teil des Fortsatzes und einer gegenüberliegenden Unterseite des sonstigen Klemmkörpers, insbesondere dem Bereich mit der Klemmschraubengewindebohrung, entspricht. Mit Sammelschienen geringerer Stärke lässt sich die Sammelschienenabgreifklemme kombinieren, indem zum Beispiel eine Klemmschraube in das in der Klemmschraubengewindebohrung gebildete Gewinde bis zu einem Kontakt mit einer Oberseite der Sammelschiene eingeschraubt wird. Eine minimale Stärke einer Sammelschiene, an der eine Sammelschienenabgreifklemme der hier und nachfolgend beschriebenen Art fixierbar ist, ist also eine Stärke, wie sie sich aus einer lichten Weite der oben beschriebenen Art abzüglich einer freien Länge des Gewindes der Klemmschraube ergibt. Theoretisch reicht das freie Gewinde der Klemmschraube auch ohne eine in die von dem Fortsatz gebildete Ausnehmung eingeführte Sammelschiene bis zu dem als Anschlag fungierenden Teil des Fortsatzes, so dass auch sehr dünne Sammelschienen sicher kontaktierbar sind. In der Praxis haben Sammelschienen allerdings eine durch statische Erwägungen bestimmte Mindeststärke, die auch ohne die Sammelschiene z.B. zu verbiegen oder Ähnliches ein Fixieren einer oder mehrerer Sammelschienenabgreifklemmen erlaubt. Ausgehend von dieser Prämisse lässt sich die Sammelschienenabgreifklemme mit Sammelschienen beliebiger Stärke unterhalb der oben beschriebenen maximalen Stärke sicher verbinden.For further embodiments of the busbar crocodile clip it is provided that a recess determined by the geometry of the hook-shaped extension between the part of the extension that functions as a stop and an underside of the other clamping body, in particular in the area of a screw threaded hole, is a combination of the busbar crocodile clip with busbars of different thicknesses and width allowed. A maximum thickness of busbars, on which a busbar crocodile clip of the type described here and below can be fixed, is a thickness that corresponds to a clear distance between the part of the extension acting as a stop and an opposite underside of the other clamping body, in particular the area with the clamping screw threaded bore , corresponds. The busbar crocodile clip can be combined with busbars of lesser thickness, for example by screwing a clamping screw into the thread formed in the clamping screw threaded bore until it makes contact with an upper side of the busbar. A minimum thickness of a busbar on which a busbar crocodile clip of the type described here and below can be fixed is a thickness that results from a clear width of the type described above minus a free length of the thread of the clamping screw. Theoretically, the free thread of the clamping screw extends even without a busbar inserted into the recess formed by the extension to the part of the extension that functions as a stop, so that even very thin busbars can be reliably contacted. In practice, however, busbars have a minimum thickness determined by static considerations, which can be achieved even without the busbar, e.g. to bend or the like a fixation of one or more busbar crocodile clips allowed. Based on this premise, the busbar crocodile clip can be securely connected to busbars of any thickness below the maximum thickness described above.
Wenn das Gehäuse auch den hakenförmigen Fortsatz abgesehen von der Ausnehmung zum Kombinieren mit der Sammelschiene umschließt, ist ein weitestmöglicher Berührungsschutz der stromführenden Teile gegeben. Zudem kann auf diese Weise der Fortsatz mit dem dort gebildeten Gehäuseabschnitt in die Gestaltung der Sammelschienenabgreifklemme insgesamt einbezogen werden, so dass sich ein ansprechendes Äußeres ergibt. Der Berührungsschutz kann noch weiter verbessert werden, wenn die Sammelschiene mit Abdeckungen, z.B. Abdeckkappen, ausgerüstet wird, die angrenzend an die Sammelschienenabgreifklemme mit der Stromsammelschiene kombiniert werden, z.B. durch Aufschieben, Aufrasten usw.If the housing also encloses the hook-shaped extension apart from the recess for combining with the busbar, the current-carrying parts are protected as much as possible. In addition, the extension with the housing section formed there can be incorporated into the design in this way the busbar alligator clip must be included as a whole, so that the result is an attractive appearance. The contact protection can be improved even further if the busbar is equipped with covers, e.g. cover caps, which are combined with the busbar adjacent to the busbar crocodile clip, e.g. by sliding on, snapping on, etc.
Wenn die Sammelschienenabgreifklemme mit ihrem Gehäuse im an einer Sammelschiene angebrachten Zustand eine Oberfläche der Sammelschiene abdeckt, ist ebenfalls ein wirksamer Berührungsschutz erreicht. Bedienpersonal, das z.B. beim Anschließen oder beim Lösen elektrischer Leiter von einer Sammelschienenabgreifklemme mit einem Schraubendreher abrutscht, kann nicht mit den von dem Gehäuse der Sammelschienenabgreifklemme abgedeckten Bereich der Oberfläche der Sammelschiene in Kontakt kommen, so dass eine Gefahr für Bedienpersonal verringert ist. Wenn zudem die Sammelschienen mit entsprechenden Abdeckkappen ausgerüstet werden, kann die Stromverteilung annähernd fingerkuppensicher gestaltet werden.If the busbar alligator clip with its housing covers a surface of the busbar when it is attached to a busbar, effective protection against contact is also achieved. Operating personnel, e.g. slips off when connecting or disconnecting electrical conductors from a busbar crocodile clip with a screwdriver, cannot come into contact with the area of the surface of the busbar covered by the housing of the busbar crocodile clip, so that a risk for operating personnel is reduced. If the busbars are also equipped with appropriate cover caps, the power distribution can be made almost fingertip safe.
Wenn eine zum Fixieren der Sammelschienenabgreifklemme an der Sammelschiene bestimmte Klemmschraube oder dergleichen von im Bereich des Gehäuseoberteils vorgesehenen Betätigungselementen zum Fixieren elektrischer Leiter an der Sammelschienenabgreifklemme, zum Beispiel Federkraftklemmen, zurückgesetzt ist, ist auf einfache Art und Weise ein Berührungsschutz und zudem für Bedienpersonal eine Möglichkeit geschaffen, diejenigen Teile (Klemmschraube, Betätigungselement etc.) zu identifizieren, die für eine Fixierung der Sammelschienenabgreifklemme an der Sammelschiene einerseits oder zum Anschluss elektrischer Leiter an die Sammelschienenabgreifklemme andererseits vorgesehen sind. Fehlbedienungen sind so weitestgehend ausgeschlossen und Bedienpersonal wird eine korrekte Verwendung von Klemmschraube, Betätigungselement etc. an der Oberseite der Sammelschienenabgreifklemme intuitiv vornehmen.If a clamping screw or the like intended for fixing the busbar alligator clip to the busbar is reset by actuating elements provided in the area of the upper part of the housing for fixing electrical conductors to the busbar alligator clamp, for example spring-loaded clamps, contact protection is created in a simple manner and also provides a possibility for operating personnel to identify those parts (clamping screw, actuating element, etc.) which are provided for fixing the busbar crocodile clip on the one hand or for connecting electrical conductors to the busbar crocodile clip on the other hand. Incorrect operation is largely ruled out and operating personnel will intuitively use the clamping screw, actuating element, etc. on the top of the busbar crocodile clip correctly.

Bei der in
Der hakenförmige Fortsatz 18 ist einstückig ausgeführt und einstückig mit dem Klemmkörper 16 verbunden. Der Klemmkörper 16 bildet also mit seinem hakenförmigen Fortsatz 18 einen geformten Metallblock. Mit der Klemmschraube 22 ist die Sammelschienenabgreifklemme 10 an der Sammelschiene 12 fixierbar, indem die Sammelschiene 12 mittels der Klemmschraube 22 sowie dem als Anschlag fungierenden Teil des Fortsatzes 18 eingespannt wird. Die Sammelschiene 12 befindet sich dabei in einer durch den Klemmkörper 16 und seinen hakenförmigen Fortsatz 18 gebildeten Ausnehmung 30 (
Durch diese Fixierung ist aber gleichzeitig auch ein elektrisch ausgesprochen belastbarer und dauerhafter Kontakt zwischen der Sammelschienenabgreifklemme 10 und dem Klemmkörper 16 hergestellt. Bei einer elektrisch leitenden Klemmschraube 22 ergibt sich ebenfalls über den mechanischen Kontakt der Klemmschraube 22 mit der Sammelschiene 12 ein elektrisch leitender Kontakt zwischen dem Klemmkörper 16 und der Sammelschiene 12. Indem die Sammelschiene 12 mittels der Klemmschraube 22 und des als Anschlag fungierenden Teils des Fortsatzes 18 eingespannt wird, ergibt sich also ein großflächiger elektrisch leitender Kontakt zu unterschiedlichen Oberflächenabschnitten der Sammelschiene 12, nämlich zwischen einem Oberflächenabschnitten der Sammelschiene 12 und einem Oberflächenabschnitt des Klemmkörpers 16 im Bereich des hakenförmigen Fortsatzes 18 sowie zwischen einem weiteren Oberflächenabschnitt der Sammelschiene 12 und einem Oberflächenabschnitt der Klemmschraube 22, die aufgrund ihrer Führung in der in dem Klemmkörper 16 gebildeten Klemmschraubengewindebohrung 20 selbst elektrisch leitend mit dem Klemmkörper 16 verbunden ist.This fixation, however, also creates a permanent contact between the

Die Sammelschienenabgreifklemme 10 weist auf einer von dem Fortsatz 18 abgewandten Oberseite 28 eine oder mehrere Leitereinführöffnungen 26 auf - beim gezeigten Beispiel zwei Leitereinführöffnungen 26, nämlich auf beiden Seiten einer Mittelachse im Bereich der Klemmschraube 22 jeweils eine Leitereinführöffnung 26. Zu jeder Leitereinführöffnung 26 gehört eine Werkzeugeinführöffnung 36. Beim gezeigten Ausführungsbeispiel befinden sich die Werkzeugeinführöffnungen 36 ausgehend von der Mittelachse der Sammelschienenabgreifklemme 10 im Anschluss an jede Leitereinführöffnung 26.The

Das Gehäuseinnenteil 40 trägt das oder jedes Betätigungselement 34 der Sammelschienenabgreifklemme 10 sowie den Klemmkörper 16. Zur Aufnahme jeweils einer Federkraftklemme 34 ist im Gehäuseinnenteil 40 eine Klemmfedersitzkontur zur zumindest abschnittsweise formschlüssigen Aufnahme und Fixierung einer Federkraftklemme 34 gebildet. Zur Halterung des Klemmkörpers 16 weist das Gehäuseinnenteil 40 bei der gezeigten Ausführungsform zwei Nasen 44 auf, die in entsprechende Ausnehmungen 46 im Klemmkörper 16 eingreifen (in der Darstellung in
Beim gezeigten Ausführungsbeispiel ist eine grundsätzlich optionale Konfiguration gezeigt, bei der auch jeweils eines der freien Enden der Klemmfeder/Federkraftklemme 34 in die Ausnehmung 46 im Klemmkörper 16 eingreift. Dieses freie Ende der Federkraftklemmen 34 schließt an einem in der Darstellung (

Bei der in den Figuren gezeigten Ausführungsform weist der Klemmkörper 16 auf seiner Kontaktfläche 52 zur Verbesserung der Halterung eines Leiterendes optional ein oder mehrere Kerbmittel auf, zum Beispiel in Form der gezeigten Rippen (nicht bezeichnet). Das jeweilige Kerbmittel, insbesondere die oder jede Rippe, kerbt mit ihrer dem Leiterende zugewandten Oberfläche bzw. Kante die Oberfläche des Leiterendes ein. Eine ähnliche Kerbwirkung ist mit dem Ende des beweglichen Schenkels der Federkraftklemme 34 verbunden. Bei zumindest einer derartigen Rippe auf den Kontaktflächen 52 des Klemmkörpers 16 wird das Leiterende durch beidseitige Einkerbung zusätzlich gehalten.In the embodiment shown in the figures, the clamping
Hinzuweisen ist noch darauf, dass die Klemmschraube 22 deutlich oberhalb der Klemmschraubengewindebohrung 20 gezeigt ist. Bei einer in die Klemmschraubengewindebohrung 20 eingeschraubten Klemmschraube 22 befindet sich der Kopf der Klemmschraube 22 deutlich unterhalb der durch die Oberfläche des Gehäuseinnenteils 40 definierten Oberseite 28 der Sammelschienenabgreifklemme 10. Nach dem Anziehen der Klemmschraube 22 zum Fixieren der Sammelschienenabgreifklemme 10 an einer Sammelschiene 12 ist der Kopf der Klemmschraube 22 noch weiter von der Oberseite 28 zurückgesetzt. Dies wirkt als Berührungsschutz und mit einem passenden Querschnitt der zum Einführen der Klemmschraube 22 vorgesehenen Öffnung in der Oberseite 28 der Sammelschienenabgreifklemme 10 ist diese fingersicher, zumal die Federkraftklemmen 34 im Innern des Gehäuses 14 ebenfalls weit von der Oberseite 28 zurückgesetzt sind.It should also be pointed out that the clamping
Mit der Klemmschraube 22 zum Fixieren der Sammelschienenabgreifklemme 10 an der jeweiligen Sammelschiene 12 einerseits und Federkraftklemmen 34 zum Fixieren angeschlossener Leiterenden andererseits kann die Sammelschienenabgreifklemme 10 zum Beispiel kurzzeitig von der Sammelschiene 12 gelöst werden, um etwa eine Position der Sammelschienenabgreifklemme 10 an der Sammelschiene 12 zu ändern, ohne dass dafür an die Sammelschienenabgreifklemme 10 eventuell bereits angeschlossene elektrische Leiter 32 ebenfalls gelöst werden müssten.With the clamping
