Definitions
- the invention relates to a screwless clamping device, where a resilient element is to be connected Element jammed against a base element.
- a resilient element is to be connected Element jammed against a base element.
- This principle work both electrical and mechanical terminals in many forms. Usually deflects Spring element laterally along a longer bending line, see above that special shapes and limitations for harder springs the travel over longer spring structures were provided (DE-A-3 526 494, DE-U-8 601 687).
- the invention has for its object a screwless Clamping device with a resilient element to create the developed a large contact force due to its special shape and is compact.
- the solution to the described problem is solved according to the invention by a screwless clamping device according to claim 1.
- the resilient element is essentially ring-shaped trained and shaped such that a movable Leg across its cross-section onto its other leg of the resilient element transverse to its cross section during the clamping process Transmits power, the flexibility of the element limited to the cross-section and in the cross-sectional plane is.
- power transmission across or perpendicular to the cross-section can be combined with the limitation of the Hard springs made of comparatively soft spring material on the way to work achieve.
- cross as in the drawing illustrated, understood: strung together imaginary cross-sections, in particular perpendicular to the cross-sectional area.
- clamps of this type can as mechanical fasteners or at Provision for sufficient electrical conductivity also as electrical connecting elements are used.
- FR-A-2 694 846 In another known clamping device (FR-A-2 694 846) is in principle the well-known ball snap lock used to hold terminal blocks on mounting rails.
- a essentially annular spring element is in one Recording held and snaps in the working state Support rail by the spring element engages behind it and does not act resiliently on this.
- a spring element rolled from sheet metal is also known (US-A-3 968 323), one leg of which abuts the other. It is not a clamping device in terms of of the spring element.
- the spring element is under load in its mobility not even across its cross-section limited.
- this is resilient Element designed in a ring, but in one sector interrupted.
- the legs of the resilient element are in theirs Mobility in a direction across the cross-section up to limited to a work area by stops, or by a clamping point.
- the mobility is in the cross-sectional plane of the resilient element through a guide channel limited.
- Such a resilient element can because of its Shaped as a C-shaped element with a round clamping area be understood.
- the resilient element be circular in cross section. It on the other hand, can be band-shaped in its cross section, that is flat, be formed and made of ribbon-shaped material will.
- the screwless clamp in the listed versions can be used in a PE terminal block like a terminal block be used on the support foot for a mounting rail.
- Edge side for mounting on the mounting rail can be via a slot for a mounting rail edge above an oblique holding contour the described screwless clamp can be arranged so that they are clamped onto an inserted mounting rail edge the mounting rail edge jammed against the holding contour or clamped.
- the screwless clamp can be in one of the designs described also in an N disconnect terminal opposite one Rail guide channel can be arranged so that a to be connected Busbar or a slide switch to hold a track in different working positions can be.
- the screwless Clamps each consist of a resilient element 2, the is compact and is shaped such that a movable Leg 3 of the resilient element transverse to his Cross section when clamping force on his other leg transmits.
- the mobility of the resilient element 2 is here across the cross-section except for a work area limited by stops 4.
- the resilient elements are annular executed, interrupted in one sector.
- the resilient elements 2 can be circular in cross section be executed or band-shaped.
- the screwless clamp is in the embodiment according to the Drawing at the top left as a terminal for connecting a busbar 6 used.
- the resilient element 2 is for this purpose electrically conductive material, for example in the manner of a Bronze spring, made or made of harder material with electric conductive coating.
- the screwless one Clamp used in a slide valve 7, for the a left connector position and a right disconnect position is illustrated.
- the screwless clamp in the middle above works against a base element 8, which is caused by saddles the slide gate in certain working positions Moving saves. Such a structure described you can find it in principle for connecting to a power rail with N disconnect terminals.
- the screwless clamps allow you to rebound their springy ones Elements 2 an emigration of the legs within one Work area until it stops on one or both of the stops 4 queue. The force effect increases accordingly the screwless clamp.
