Definitions

the invention relates to a sleeve-shaped clamping element the specified in the preamble of claim 1 Art.
Such clamping elements are from DE-Ausschschrift 23 39th 800 and known from DE Patent 32 39 708.
the in trained in its entirety as a metal clamping spring Sleeve body of such clamping elements has over its entire Cross-section a constant thickness, which is the case with both Contact, namely when cutting into the insulating jacket of the head concerned, as well as regarding the Space requirement of the clamping element in the associated terminal housing is disadvantageous.
It is with respect to the mechanical stress curve with applied clamping forces of the flared sleeve body does not require him to the same thickness up to the clamping slot. Rather, it should be based on the elastically deformable area, in which the stresses when the sleeve body is jammed according to the length of the lever arm from the clamping point seen increase with constant material thickness, which is by no means cheap.
the invention is therefore based on the object, a sleeve-shaped Clamping element of the generic type create its design taking into account the bending stress curve is optimized in the clamped state.
the material rejuvenation has an effect of the clamping leg on the clamping slot itself due to a lower material thickness in the cutting area of the Clamping leg out, which means that when the non-stripped electrical conductor into the clamping slot the cutting of the insulating jacket of the conductor favors becomes.
the constant miniaturization of the building blocks for the terminal technology in cross-section tapered clamping leg space advantages because it is given the available space further away from the clamping slot can expand or when space is limited Head can contact unchanged cross section without that the cutting and clamping forces are impaired.
the sleeve-shaped clamping element according to the invention the usual has a symmetrical design with two clamping legs, both of them are designed with a tapering cross-section. You get there so a uniform course of the mechanical tension in the clamping legs, the bending range of which is extended can be, whereby higher restoring forces are possible.
terminal housing 1 shows a terminal housing 1, in which there is a terminal space 2, which is perpendicular to the plane of representation extends. In it there is one with his Arranged in the same direction extending sleeve body 3, that of a metal with suitable spring properties exists and at least electrically with a busbar 7 is connected.
the sleeve body 3 represents a clamping element, which a clamping slot 4 along its upper apex region having. Through this clamping slot 4 one goes through one dash-dotted line indicated plane through to the entire sleeve body 3 is mirror-symmetrical is.
the sleeve body 3 has seen in cross section a box profile or a U-profile, the U-legs form two opposing clamping legs 5, which are integrally connected to one another via the lower U-web 6 are.
the U-web 6 is fixed, in particular electrically conductively connected to the busbar 7.
the U-web 6 goes over rounded arches 8 in the spring legs 5 over that run up to bends 9, of which from them converging towards each other, sloping roof extending leg ends 10, which end with Cut 11 limit the clamping slot 4.
the peculiarity of the sleeve body 3 is that the Clamp leg 5 upwards, that is towards the clamping slot 4 taper in cross-section.
the tapered area extends between the rounded arches 8 at the transition to the U-bridge 6 and the upper bends 9 so that the leg ends 10 from the bends 9 to the clamping slot 4 or their cutting edges 11 a substantially constant Cross section.
the electrical conductor is inserted 12 the sleeve body 3 expanded, i.e. its elastic Clamping legs 5 now have outer sides lying parallel to one another, up to their position on the clamping slot 4 between the blades 11 have a larger spring or clamping path of the two clamping legs 5 is available. Also recognizes here that the ends 10 the clamping leg 5 more easily into the insulation material 13 of the conductor 12 can penetrate.
