Definitions
- the invention relates to a screwless clamp, in which a resilient element clamps an element to be connected against a base element.
- a resilient element clamps an element to be connected against a base element.
- both electrical and mechanical connection terminals work in many forms.
- a spring element springs out laterally along a longer bending line, so that special shapes and limitations of the spring travel over longer spring structures have been provided for harder springs (DE-A-3 526 494, DE-U-8 601 687).
- the invention has for its object to form a resilient element that develops large contact forces compact by special shape.
- the described object is achieved according to the invention by a screwless clamp according to claim 1.
- the resilient element is shaped such that a movable leg across its cross-section on another leg of the resilient element transmits force transversely to its cross-section during the clamping process, the mobility of the element is limited transversely or perpendicular to the cross-section and in the cross-sectional plane.
- the force transmission across or perpendicular to the cross-section in conjunction with the limitation of the travel, enables hard springs to be obtained from comparatively soft spring material.
- Such clamps can be used as mechanical connecting elements or, if sufficient electrical conductivity is provided, also as electrical connecting elements.
- the resilient element is ring-shaped, but is interrupted in one sector.
- the legs of the resilient element are movable in a direction transverse to the cross-section limited to a work area by stops, or by a clamping point.
- the mobility of the resilient element is limited by a guide channel.
- a resilient element can be understood as a C-shaped element with a round clamping area because of its shape.
- the resilient element can have a circular cross section.
- its cross-section can be in the form of a band, that is to say flat, and can be produced from band-shaped material.
- the screwless terminal in the versions listed can be used in a PE connection terminal in the manner of a terminal block on the holding foot for a mounting rail.
- the screwless clamp described above can be arranged above a slot for a mounting rail edge above an oblique holding contour, so that it clamps or clamps the mounting rail edge against the holding contour on an inserted mounting rail edge.
- the screwless terminal can also be arranged in one of the described embodiments in an N disconnect terminal opposite a rail guide channel, so that a busbar to be connected or a disconnect slide for holding a busbar can be fixed in various working positions.
- the screwless clamps each consist of a resilient element 2, which is compact and is shaped such that a movable leg 3 of the resilient element transverse to it Cross-section transfers force to his other leg during the clamping process.
- the mobility of the resilient element 2 is limited transversely to the cross section except for a working area by stops 4.
- the resilient element 2 is delimited by a guide channel 5.
- the resilient elements are designed ring-shaped, wherein they are interrupted in one sector.
- the resilient elements 2 can be circular in cross section or band-shaped.
- the screwless terminal is used in the exemplary embodiment according to the drawing at the top left as a terminal for connecting a busbar 6.
- the resilient element 2 is made of electrically conductive material, for example in the manner of a bronze spring, or of harder material with an electrically conductive coating.
- the screwless clamp is inserted in a disconnect slide 7, for which a left connection position and a right disconnection position are illustrated.
- the screwless clamp in the middle at the top works against a base element 8, which secures the separating slide in certain working positions against shifting.
- Such a structure described for connection to a busbar can be found in principle in the case of N isolating terminals.
- screwless terminal 1 In the drawing, another area of use for screwless terminal 1 is shown at the bottom right.
- the screwless terminal 1 In order to establish mechanical connection and electrical contact to a mounting rail 9, as is desirable in the case of a PE connecting terminal, the screwless terminal 1 is arranged on the edge side of the mounting rail 9 via a slot 10 for a mounting rail edge and above an oblique holding contour 11.
- the terminal block In the slot 10, the terminal block can be raised to the top left as shown in the drawing, that is to say inserted obliquely on the edge of the mounting rail 9 and clamped between the spring element and the inner corner of the oblique holding contour 11 by pressing against the resilient element 2.
- the screwless clamps allow the legs to migrate within a working area when their resilient elements 2 rebound until they abut one or both of the stops 4. The force of the screwless clamp increases accordingly.
