Abstract
A connecting device may be provided comprising a positive connecting element and a negative connecting element, wherein the positive connecting element has an elevation arranged on a base surface and the negative connecting element has a depression introduced into a contact surface, into which the elevation of the positive connecting element can be introduced, wherein the positive and the negative connecting element may be connected to one another by rotation relative to one another.
Claims16
A connecting device comprising:
- a positive connecting element and
- a negative connecting element,
- wherein the positive connecting element has a base area and an elevation arranged on the base area,
- wherein the elevation has n pegs, where n is greater than or equal to two, wherein the n pegs are arranged about a common center axis which is perpendicular to the base area,
- wherein each of the pegs has an end face which delimits said peg in the radial direction with respect to the center axis,
- wherein the end faces enclose at least one angle of less than 90° with the base area,
- wherein the negative connecting element has a contact surface with a depression which is introduced in the contact surface,
- wherein the depression is delimited in the radial direction with respect to a depression axis perpendicular to the contact surface by an inner wall of the depression,
- wherein the inner wall has n insert portions with an insert radius with respect to the depression axis,
- wherein the inner wall has 2n retaining portions, wherein each side of each of the n insert portions is adjacent to one of the 2n retaining portions along the inner wall such that a retaining state can be achieved by rotating the positive connecting element with respect to the negative connecting element in either direction about the depression axis or the center axis;
- wherein the inner wall of the depression has a stop region adjoining each of the retaining portions to delimit the respective retaining portion at its end facing away from that insert portion to which the retaining portion is adjacent
- wherein the inner wall in a region of each of the retaining portions encloses an angle of greater than 270° with the contact surface and has a maximum spacing at a point at which the inner wall adjoins the contact surface, referred to as the retaining spacing, from the depression axis that is smaller than the insert radius,
- wherein a spacing between the end faces and the center axis is smaller than or the same as the insert radius and greater than the retaining spacing.

A connecting device comprising a negative connecting element,
- wherein the negative connecting element has a contact surface with a depression which is introduced in the contact surface,
- wherein the depression is delimited in a radial direction with respect to a depression axis perpendicular to the contact surface by an inner wall of the depression,
- wherein the inner wall has n insert portions with an insert radius with respect to the depression axis, where n is greater than or equal to two,
- wherein the inner wall has 2n retaining portions, wherein each side of each of the n insert portions is adjacent to one of the 2n retaining portions along the inner wall such that a retaining state can be achieved by rotating the positive connecting element with respect to the negative connecting element in either direction about the depression axis or the center axis;
- wherein the inner wall of the depression has a stop region adjoining each of the retaining portions to delimit the respective retaining portion at its end facing away from that insert portion to which the retaining portion is adjacent
- wherein the inner wall in a region of each of the retaining portions encloses an angle of greater than 270° with the contact surface and has a maximum spacing at a point at which the inner wall adjoins the contact surface, referred to as the retaining spacing, from the depression axis that is smaller than the insert radius.
