These components are at least the housing of the busbar alligator clip, the Klemmkör- per as well as or the means for electrically conductive contacting a conductor, so for example a spring terminal or a plurality of spring terminals.
- the fixing of the busbar alligator clip to the respective busbar is effected, for example, by means of a clamping screw screwed into the clamping body. Alternatively, this fixation can also be realized by means of a spring force-based clamping device.
- a significant advantage of the busbar aisle clamp according to the invention consists in its optimized design with regard to simple production. This is also evident in a method for producing a busbar aisle clamp of the type described here and below. In such a method, the following is provided: There are placed as a means for electrically conductive contacting a guided up to the busbar alligator conductor spring force terminals or other actuating means in Klemmfedertechnik in the housing inner part in recesses provided for this purpose. Furthermore, the clamping body is placed in the housing inner part.

- clamping body retaining means For example, recesses in the clamping body and, for engagement in these recesses, certain lugs on the housing come into consideration as clamping body retaining means.
- the housing holds, for example, spring terminals, which in the following for better readability, but without omission of a more general validity instead of means for electrically conductive contacting a guided up to the busbar alligator conductor are mentioned, but which are still always read, in a defined position ,
- clamping body holding means in the form of recesses and lugs and the clamping body is held in relation to the housing in a defined position. This ensures overall that the spring-loaded terminals, the clamping body and the housing are in a defined, the function of the busbar alligator enabling relative position to each other.
- the busbar alligator clamp act as a means for electrically conductive contacting a conductor spring terminals, which have a fixed in the housing or by means of the housing leg and a movable leg, wherein a free end of each fixed leg engages in the recess in the clamping body.
- the spring-loaded terminals are connected to the clamping body (at least mechanically) and the clamping body holding means, for example in the form of the recesses in Clamping, ensure immediately a defined relative position of the clamp body to the spring terminals.
- the overall result is that the spring-loaded terminals, the clamping body and the housing are located in a defined relative position with respect to each other, enabling the busbar alligator clamp to function.
- the clamping body for electrically contacting a conductor comprises lateral contact surfaces and on the surfaces thereof at least one notch means, for example a notch means in the form of at least one rib extending transversely to the longitudinal axis of an inserted conductor end.
- a notch means or such notch means ensure an increase in the holding force acting on a conductor connected to the busbar tapping terminal.

- the clamping body can be made in one operation and the extension is mechanically sufficiently firmly connected to the clamping body to the when clamping a busbar, especially when clamping a busbar between a clamping screw and the sprag extension to be able to absorb forces occurring.
- the clamping device for fixing the busbar pick-up clamp to the busbar is independent of one or more spring-loaded terminals, conductors can be connected to or detached from the busbar pick-up terminal without loosening the fixation of the busbar pick-up terminal with the busbar and vice versa.
- a solution of the fixation of the busbar alligator clip from the busbar is considered, for example, when its position on the busbar is to be changed, for example, to attach further busbar aisle clips to the busbar. It is also advantageous for such a situation when the electrical busbars that have already been connected to the busbar pickup terminal need not be loosened and later reconnected.
- the housing is an at least two-part housing with a housing inner part and the housing inner part receiving housing outer part and that the housing side KlemmISEhal- tesch, so for example the engaging in the recesses in the clamping body lugs, part of the housing inner part are.

- Clamping in particular the area with the clamping screw threaded hole corresponds.
- the busbar gripping blade can be combined by, for example, screwing a clamping screw into the thread formed in the clamping screw threaded hole up to contact with a top of the busbar.
- a minimum thickness of a busbar, to which a busbar clamp of the type described here and below can be fixed, is therefore a strength as it results from a clearance of the type described above minus a free length of the thread of the clamping screw.
- the free thread of the clamping screw extends without a busbar introduced into the recess formed by the extension up to the part of the extension which acts as a stop, so that even very thin busbars can be securely contacted.
- busbars In practice, busbars, however, have a minimum strength determined by static considerations, which, for example, allows bending without the busbar or the like allowing a fixing of one or more busbar terminals. Based on this premise, the busbar clamp can be securely connected to busbars of any size below the maximum strength described above. If the housing also encloses the hook-shaped extension apart from the recess for combination with the busbar, the widest possible contact protection of the current-carrying parts is provided.

- the head of the clamping screw 22 is clearly below the upper side 28 of the busbar tapping clamp 10 defined by the surface of the inner housing part 40. After tightening the clamping screw 22 for fixing the Samnnelschienenabgreifklennnne 10 to a busbar 12 the head of the clamping screw 22 is further set back from the top 28.
- the bus bar pickup terminal 10 can be momentarily released from the bus bar 12 to change about a position of the bus bar picking terminal 10 at the bus bar 12 , without that for the busbar alligator 10 may have already connected electrical conductors 32 would also have to be solved.
- the illustrations from Figure 3, especially the illustration in Figure 3, can be seen in a comparison with the illustration in Figure 1 and the busbar 12 shown there that the busbar aisle clamp 10 with its housing 14 in attached to a busbar 12 state part of a surface the busbar 12 covers.
- the conductor insertion openings 26 begin significantly above the busbar 12 (or at another orientation well ahead of the busbar 12), so that the risk of inadvertent contact with the surface of the busbar 12 is already significantly reduced thereby.
- the width (measured transverse to a busbar 12) of the busbar tapping terminal 10 and the lateral coverage of the respective busbar 12 caused thereby provide additional security.
- FIG. 8 shows the cut busbar alligator clip 10 according to FIG. 7 with conductor ends inserted into the conductor insertion openings 26 and into the connection spaces 50. It can be seen here that the conductor ends are pressed against one of the contact surfaces 52 of the clamping body 16 by means of the movable limb of the respective spring force terminal 34 in order to obtain an electrically conductive contact with the clamping body 16. It can be seen further that a conductor 32 connected to the busbar alligator clip 10 can be released again from the busbar alligator 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 terminal 34 by means of the tool 38 is further deflected (further than by the conductor end itself), so that the free end of the movable leg of the spring terminal 34 is disengaged from the surface of the conductor end. Then, the conductor end can be pulled out of the terminal space 50 and the conductor insertion opening 26.
- the illustration in FIG. 9 shows, on the one hand, the busbar alligator clip 10 in a representation as in FIG. 7 and in a sectional illustration along the section line labeled AB.
- the section along the section line AB runs just above the horizontal leg of the spring-loaded terminals 34 in the illustration.
- the view of the same is accordingly Legs of the spring-loaded terminals 34 and the eyelet therein and on the below connecting terminal space 50 free.
- the illustration in FIG. 10 also shows snapshots in a schematically simplified manner during the manufacture / assembly of a busbar pick-up terminal 10. It is shown that in a first step, first the spring-force terminals 34 are placed in the housing inner part 40 , namely in each case in a designated Klemmfedersitzkontur.
- 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 clamp body - or generally the respective clamp body holding means 44, 46 - engage each other.
- the sequence of steps 1 and 2 can also be reversed for its production.
- This component 40, 16, 34 is combined in total with the housing outer part 42 and pushed into the housing outer part 42 for this purpose.
- the housing inner part 40 can be connected to the housing outer part 42 latching. This completes the manufacture / assembly of the busbar aisle clamp 10 without tools.
