- a contacting element for the electrical connection of a contact terminal of an electrical cell, in particular a battery cell comprising a deformation section and at least two clamping edges, which are supported on opposite end portions of the at least one deformation section.
- the deformation section has the property that it can change its shape, if appropriate while providing a force. This leads to a change in the relative position of the two opposite end portions of the deformation section. Since the two clamping edges are supported on the end sections, their relative position to one another is also caused by a deformation of the deformation section.
- the deformation section can be changed in such a way that the two clamping edges move towards one another and thus pinching of a clamping edge arranged between two clamping edges.
- Neten contact terminal in particular an electrode or a cable lug allow.
- the clamping creates a sufficiently stable connection between the contacting element and the contact connection.

- ing end portions are changed in a change in shape of the deformation section.

Subsequently, a contacting element is inserted into the bore and brought into its axial position, so that the electrodes 18 are at the same axial height to the corresponding receiving spaces 12. Thereafter, the Kontak- t istselement is rotated by 45 °, whereby the receiving spaces 12 overlap with the projections 28 of the electrodes 18. The guessed the Clamping edges 8, 9, 10, 11 of the contacting unit 1 in contact with the electrodes 18, but still without jamming. A small distance or clearance between the clamping edges and the electrodes 18 may be present.
- the contacting unit 1 is treated with heat, as a result of which the deformation section 2 changes its shape, which in particular leads to the clamping edges 8, 9 and 10, 11 moving towards each other, thereby jamming the electrodes 18 in the receiving spaces 12.
- the contacting unit ⁇ ⁇ and 1 4 is inserted into the bore 21 of a cable lug 20 during the assembly process, which is connected in the same way with the contacting element, as the electrode 18th
- an insulator 26 can be introduced between two contacting units 1, which on the one hand forms an insulation between two contacting units 1 arranged together in a bore.
- the insulator 26 can serve as a mechanical spacer of two contacting units 1.
