Definitions
- the invention relates to a tension spring terminal for electrical conductors, with a busbar and a tension spring, which has a leg resting on the conductor rail, has a curved back area and a clamping leg in which a Passage opening for the busbar is located, the lower limit of the Passage an inserted electrical conductor at the bottom of the The busbar is stuck.
- tension spring clamps are in their basic construction known (DE 296 08 178 U1, DE 42 377 33 C1).
- the passage opening in the clamping leg is through which the busbar is inserted and through which the electrical Head is inserted, window-shaped, the lower straight Boundary edge of the window the clamping edge for clamping the inserted Conductor forms at the bottom of the busbar.
- the conductor can only be used with such a spring clamp electrical conductor can be connected.
- the present invention is based on the object, the possible uses such tension spring terminals to enlarge significantly.
- the solution according to the invention is that the lower limit of the passage opening through to free end of the clamping leg converging bevels towards the center of the conductor is trained.
- Corresponding recesses are provided, in which the bevels at Ladder clamping can occur.
- the essentially loop-shaped tension spring 1 of the tension spring clamp has one leg lying on the cooperating busbar 2 3, a back area 4 and an adjoining clamping leg 5.
- the clamping leg 5 there is a passage opening 6 through which the busbar 2 occurs when the tension spring is placed on the busbar becomes.
- Figure a illustrates that this centering a particularly secure clamping for a single conductor 10 to be connected and thus contacting, because in relation to the clamping leg 5 result in several clamping points, indicated by arrows in Figure a are.
- Figure b of Figure 3 illustrates the reliable clamping and thus contacting two conductors of the same diameter, their position to each other, to Clamp legs and to the busbar in the clamping phase thanks to the centering and compaction results automatically.
- Figure c of the clamping scheme according to Figure 3 illustrates the also guaranteed reliable clamping thanks to the centering and compacting in the Taper zone also for two conductors of different diameters.
- the illustration d of the clamping scheme according to FIG. 3 illustrates that under extensive conditions Entry of the bevels 7 of the passage opening 6 of the clamping leg 5 into the Recesses 8 also a very small conductor in the bottom area of the taper zone can be reliably clamped and contacted.
- the rejuvenation zone can also be reliable and easy too Multi-wire conductors, especially fine-wire conductors, reliably connected become.
- the underside of the busbar 2 is possible Conductor connection area provided with a corrugation 11, which is particularly good Down the ladder.
- the center can a bulge 12 may be provided on the underside of the busbar 2 in which in some applications is a conductor with part of its outer sheath can insert, which can also contribute to secure fixing.
- it may be appropriate to the bottom of the busbar insofar as to be left in the possible clamping zone as a whole, as in FIG 4 shown.
