Busbar adapter, an arrangement with a busbar, and a method for connecting a busbar adapter in a busbar

The busbar adapter in accordance with wherein

• a first of the contact elements has a cranked section, and
• a cam, which is associated with a second of the contact elements for purposes of actuating the second contact element, is arranged in a rotational position of the single camshaft in the region of the cranked section, and in another rotational position of the single camshaft outside the region of the cranked section.

A method for connecting a bus bar adapter in a bus bar, comprising:

• provision of a busbar adapter with a housing and contact elements, on each of which an electrical connection is formed, and which are displaceably arranged in the housing, in such a way that the contact elements are each arranged between an extended position, in which the electrical connection protrudes outwards in the region of a side face on the housing, and by means of the electrical connection an electrical contact can be made with a busbar, and a retracted position, in which the electrical connection is arranged in the housing and the electrical contact is broken;
• arrangement of the busbar adapter in a busbar, and
• contact made by the busbar adapter in the busbar, wherein here a single camshaft, which is arranged in the housing of the busbar adapter such that it can rotate, and has an arrangement of cams, which are each assigned to at least one of the contact elements, is rotated in such a way that at least one of the contact elements is displaced from the retracted position into the extended position, and thereby makes contact with an electrical connection of the busbar.
