Abstract
Disclosed is an arrangement for electrically contacting a component, in particular a capacitor for a power converter of a rail vehicle, wherein the component includes a protruding pin for applying and/or positioning parts in order to produce the electrical contact. The arrangement a first element which has a through-bore extending in a longitudinal direction therethrough for inserting the pin, a second element which has a through-bore extending in a longitudinal direction therethrough for inserting the pin, and a contact plate of an electrically conductive material, which comprises a contact plate end region. The contact plate end region has a slot extending from a free end into the contact plate end region and the width of the slot is sufficiently large to accommodate the pin.

An arrangement for electrically contacting an electrical component, in particular, a capacitor for a power converter of a rail vehicle wherein the electrical component has a protruding pin for applying and/or positioning parts of the arrangement in order to produce the electrical contact, and wherein the arrangement comprises:
- a) a first element having a first through-hole extending in a longitudinal direction through the element for inserting the pin,
- b) a second element having a second through-hole extending in a longitudinal direction through the element for inserting the pin,
- c) a contact sheet, made of an electrically conducting material, that has a contact sheet end region used to produce the electrical contact with the electrical component wherein the contact sheet end region has a slot extending from one free end into the contact sheet end region, this slot being wide enough to accommodate the pin, and
- d) a fastening element;
- wherein the first element and/or the second element is formed of an electrically conducting material;
- wherein the first element has a first surface and the second element has a second surface;
- wherein the first element and/or the second element has at least one region protruding parallel to the longitudinal direction, this region having a contact surface facing the through-hole;
- and wherein, when the arrangement is assembled:
- the contact sheet end region makes contact with one side to the first surface and a second side opposite the first side makes contact to the second surface such that the contact sheet end region is accommodated in a sandwich-like fashion between the first and second surfaces;
- the contact sheet end region makes contact with a surface region running between the first side and the second side with the contact surface of the first and/or second element;
- the pin extends perpendicular to the first surface and the second surface through the first element, the slot of the contact sheet end region and the second element;
- and
- the fastening element is supported on the pin and presses the first and the second surfaces against the contact sheet end region.
A method for electrically contacting an electrical component, in particular a capacitor for a power converter of a rail vehicle wherein the electrical component has a protruding pin and wherein:
- a) a first element having a first through-hole extending in a longitudinal direction through the element is slipped onto the pin so that the pin extends through the first through-hole;
- b) a second element having a second through-hole extending in a longitudinal direction through the element is slipped onto the pin so that the pin extends through the second through-hole;
- c) a contact sheet end region of a contact sheet consisting of an electrically conducting material wherein the contact sheet end region has a slot extending from one free end into the contact sheet end region, extends between the first element and the second element or in contact with the first element before the second element, the contact sheet end region is slipped over the pin at an end position so that the contact sheet end region makes contact with a first side to a first surface of the first element and with a second side opposite the first side to a second surface of the second element so that the contact sheet end region is accommodated in a sandwich-like fashion between the first and second surfaces wherein the pin extends perpendicular to the first surface and the second surface through the first element, the slot of the contact sheet end region and the second element, and
- d) a fastening element is supported on the pin so that the first and the second surfaces are pressed against the contact sheet end region,
- wherein the first element and/or the second element consist is formed of an electrically conducting material and wherein the first element and/or the second element has at least one region protruding in parallel with the longitudinal direction, this region having a contact surface facing the through-hole, so that the contact sheet end region makes contact with a surface region running between the first side and the second side at the contact surface of the first and/or second element.
