DETAILED DESCRIPTION

[0026] FIG. 1 shows an example of a conductor connection terminal 1. The conductor connection terminal 1 has a housing 2 with a first end face 3 and a second end face 4 opposite the first end face 3. The two end faces 3, 4 are connected to each other via a first side face 5 and a second side face 6 opposite the first side face 5. Further, the housing 2 has an underside 7 and a top side 8, wherein the top side 8 is located opposite the underside 7. The underside 7 and the top side 8 connect the two end faces 3, 4 as well as the two side faces 5, 6 with each other. The extension from the first end face 3 to the second end face 4 or vice versa defines a longitudinal direction L of the conductor connection terminal 1.

[0027] On the first and second end faces 3, 4 there is at least one conductor insertion opening 9, above which an electrical conductor, not shown, can be fed to a conductor terminal, which is arranged in the housing 2 of the conductor connection terminal 1 and not shown in more detail. For example, the respective conductor terminal is designed as a spring-loaded terminal connection with a deflectable clamping spring, wherein the clamping spring or each of the clamping springs can be operated by the actuating lever 10 arranged, for example, on the top side 8 of the housing 2.

[0028] FIG. 1 also shows two form-fitting elements 11, 12 on the first side face 5, wherein a first form-fitting element 11 is formed as a protrusion 111. The second form-fitting element 12 has a depression 121. For example, the depression 121 can be formed by two ribs 15 protruding from the first side face 5. The two form-fitting elements are complementary to each other. The form-fitting elements 11, 12 have an extension in a vertical direction H that is essentially perpendicular to the longitudinal extension L. In this case, the form-fitting elements 11, 12 do not extend over the entire height H1 of the side face 5, but only over part of the height H1. For example, the form-fitting elements 11, 12 are spaced from the underside 7 and the top side 8. The advantage of this design is that the mounting distance or displacement distance between the conductor connection terminal 1 and another conductor connection terminal can be kept relatively small.

[0029] Between the first form-fitting element 11 and the second form-fitting element 12, a fastener 16 is also arranged, for example in the form of a gutter-shaped depression.

[0030] On the second, non-visible side face 6, there is a form-fitting element 13, which is also not visible and is formed as a protrusion 131, and a fourth form-fitting element 14, which is formed as a depression 141. The third form-fitting element 13 is also complementary to the fourth form-fitting element 14. The first form-fitting element 11 is preferably arranged point-symmetrically to the third form-fitting element 13 relative to an axis of symmetry S aligned perpendicular to the longitudinal direction L and parallel to the side faces 5, 6. Furthermore, the second form-fitting element 12 is arranged point-symmetrically to the fourth form-fitting element 14 relative to the axis of symmetry S. At a distance from the protrusion 111, 131, a boundary wall 17 is provided, which, together with the protrusion 111, 131, forms a further depression 18, which is suitable for accommodating a rib 15 of another conductor connection terminal. By means of the boundary wall 17, a lateral boundary of the depression 18 can be achieved in a simple way without increased effort.

[0031] On the second side face 6, between the third form-fitting element 13 and the fourth form-fitting element 14, a further fastener 19 is also arranged, for example in the form of a gutter-shaped depression.

[0032] The underside 7 of the housing 2 can preferably be flat and it serves advantageously as a support on a mounting plane that is not shown. It is also conceivable that depressions or snap-in hooks are provided on the underside, by means of which the conductor connection terminal 1 can be attached to a mounting plane.

[0033] FIGS. 2 to 5 show an inventive conductor connection terminal arrangement with a first conductor connection terminal 1 and a second conductor connection terminal 1 in an example, wherein the first conductor connection terminal 1 and the second conductor connection terminal 1 may be essentially identical. In particular, both conductor connection terminals 1, 1, each have a first, a second, a third and a fourth form-fitting element 11, 12, 13, 14. The first form-fitting element 11 of the first conductor connection terminal 1 interacts with the complementary fourth form-fitting element 14 of the second conductor connection terminal 1; in particular, the form-fitting elements 11, 14 are connected to each other in a form-fitting manner. The second form-fitting element 12 of the first conductor connection terminal 1 interacts with the complementary third form-fitting element 13 of the second conductor connection terminal 1; in particular, the form-fitting elements 11, 14, are connected to each other in a form-fitting manner. The first and the second conductor connection terminal 1, 1, are connected to each other by inserting the form-fitting elements 11, 14, 12, 13, in the vertical direction H, so that they are form-fittingly connected to each other in a direction of alignment A, which is oriented perpendicular to the longitudinal direction L and perpendicular to the vertical direction H (perpendicular to the planes of the side faces 5, 6). The two conductor connection terminals 1, 1, preferably form a common support plane with their undersides 7, 7. This can be achieved, for example, by providing a stop 28, 29 on one or both side faces 5, 6, which limits the insertion of a protrusion 111, 131 into a depression 121, 141. For example, two complementary protrusions 28, 29 protruding from the side face 5, 6, which are each provided with a mutually aligned stop surface perpendicular to the vertical direction H, are provided as a stop.

[0034] FIG. 2 also shows that the fasteners 16, 19 of the first conductor connection terminal 1 and the second conductor connection terminal 1, which are formed as a gutter-shaped depressions and are opposite each other in the assembled state, form a circumferential predominantly closed mount 20. For example, a snap-in mounting foot 21 can be inserted into the mount 20, which protrudes on the underside 7 of the conductor connection terminals 1, 1. For example, the end of the snap-in mounting foot 21 protruding on the underside 7 of the conductor connection terminal can be inserted into a snap-in opening of a mounting plate that is not shown and snapped into place there to fix the conductor connection terminal arrangement to the mounting plate.

[0035] FIGS. 3 and 4 each show a top view of a conductor connection terminal arrangement formed of a first conductor connection terminal 1 and a second conductor connection terminal 1. In particular, it can be seen that the circumferential mount 20, which is preferably circular at least over a section in the vertical direction H, is formed from the fasteners 16, 19 opposing each other. The fasteners 16, 19 each have a semi-circular gutter-shaped depression for this purpose. However, it is also conceivable that the cross-sectional shape of the mount 20 deviates from the circular shape, and is, for example, square, rectangular or star-shaped.

[0036] The section shown in FIG. 5 illustrates once again the form-fitting connection of a first conductor connection terminal 1 and a second conductor connection terminal 1. It becomes clear that the first form-fitting element 11 of the first conductor connection terminal 1 and the third form-fitting element 13 of the second conductor connection terminal 1 each have a dovetail-like or T-shaped cross-sectional contour. The protrusions 111, 131 protruding from the side faces 5, 6, have sections 22 protruding longitudinally in opposite directions in an area distanced from the side face 5, 6, which are connected to the side face via a rib section 23. In this way, a contour with an undercut is realized, which can be brought into engagement with a complementary mount contour of the corresponding fourth form-fitting element 14 of the second conductor connection terminal 1 and the corresponding second form-fitting element 12 of the first conductor connection terminal 1. The contours of the form-fitting elements 11, 12, 13, 14 can be rounded.

[0037] The sectional view in FIG. 6 shows a section through the dividing plane of a first conductor connection terminal 1 and a second conductor connection terminal 1, with a view of the side face 5 of the second conductor connection terminal 1. The cut protrusion 111 can be seen here of the first form-fitting element 11 of the second conductor connection terminal 1, as well as the cut protrusion 131 of the third form-fitting element 13 of the first conductor connection terminal 1. The protrusions 111, 131 are surrounded in the longitudinal direction L by two ribs 15 each of the respective complementary fourth form-fitting element 14 and the second form-fitting element 12 of the first conductor connection terminal 1.

[0038] FIG. 6 also shows a snap-in mounting foot 21 inserted and mounted in the mount 20 with a preferably essentially cylindrical base body 24, which on the one end first has snap-in hooks 25 that can be deflected resiliently, which are suitable for locking with counter snap-in sections on the housing of the conductor connection terminals 1, 1. On the other end, when assembled, the snap-in mounting foot 21 has a second, preferably resiliently deflectable snap-in hook 26 that protrudes from the underside 7, 7 of the conductor connection terminal arrangement. The second snap-in hooks 26 are suitable for attaching the conductor connection terminal arrangement to a mounting plate with a snap-in opening that is not shown.

[0039] The snap-in mounting foot 21 is preferably inserted into the mount 20 from the underside 7, 7, of the conductor connection terminal arrangement in a plug-in direction E. A stop 27 on the base body 24 of the snap-in mounting foot 21 interacting with the housing shoulder limits the insertion depth and enables a defined position of the snap-in mounting foot. The housing shoulder can preferably be formed by the ribs 15.

[0040] Such a conductor connection arrangement can be extended via the form-fitting elements 11, 12, 13, 14 with any number of other conductor connection terminals 1. The conductor connection terminals do not always have to be identical or of the same design, but they can differ from each other in terms of size, shape and/or type of conductor connection, for example. It is only necessary to have corresponding form-fitting elements 11, 12, 13, 14 on the conductor connection terminals 1 that are to be connected to each other. The various conductor connection terminals 1 can be mounted together independent of the direction.

[0041] FIG. 7 shows another example of a conductor connection terminal arrangement with a first and a second conductor connection terminal 1, 1, wherein in the mount 20 formed here, a marking carrier 30 is inserted for the inclusion of markings that are not shown.

[0042] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
