Embodiment Construction

[0027] figure 1 It shows a plan view of a star-shaped end fitting 1 with eight arcuately formed edges 4 a to 4 h as well as respective grooves 2 a to 2 h and respective groove center 3 a to 3h. In addition, in the star-shaped end fitting 1 arc-shaped contour lines 6a to 6h are also drawn, so that when the same force is exerted on the body outer edge 5 of the end fitting all over, it can be pressed evenly. Rod 7 (not shown). The curved edges 4 a to 4 h are equidistant and evenly distributed on the outer edge of the end fitting 1 with respect to the center 8 of the end fitting 1 .

[0028] exist figure 2 , the end fitting 1 is shown as a cross having four arcuately formed edges 4a to 4d. The shape of the curved edge is configured relative to the respective groove center 3a to 3d such that the distance between points on the curved edge and the respective groove center is an equal distance. The distance of the pitch.

Abstract

The invention relates to an end fitting (1) of a surge arrester (11) having a recess (2a-2h) for receiving a rod (7), wherein the rod can be pressed inside the recess by applying an outer force to the end fitting. Furthermore, a corresponding device for pressing an end fitting and a method for pressing an end fitting are described. The end fitting comprises a plurality of body edges (4a-4h) delimited in an arc shape. Spaces between points on the body edge delimited in an arc shape and a center point of the recess are equidistant. Thus it is possible to exert a uniform force on all sides on a recess and thus provide an even deformation on all sides of the recess during pressing. As a result, accordingly pressed items, for example rods within the recess, are pressed within the recess on all sides.

Description

technical field [0001] The invention relates to an electrical component, in particular an end fitting of a surge protector, having a recess for receiving a rod, wherein said rod can be pressed against said end fitting by the action of an external force applied to the end fitting. In the groove. Furthermore, the invention relates to a device and a method for clamping an end fitting of a surge protector. Background technique [0002] Electrical components for high voltage applications, especially surge protectors, consist of different components and materials. Here, there is often the inconvenience of having to connect metal parts, in particular electrical components, to other parts. One method that is suitable for this is the so-called compression of metal parts by the action of external forces on said metal parts in order to connect them to other parts made of other materials. Thus, for example in electrical technology, electrical conductors and wires are connected by cri...
