Problems solved by technology

For example, in the case of installing a battery module for a vehicle, up to 120 connection elements are simultaneously in contact with each corresponding contact element, which requires a high installation force, which in the case of inhomogeneity in the connection may Leads to a localization of the mounting forces in some small numbers of components, which are thus damaged due to the high mounting forces

Embodiment Construction

[0036] In the figures, identical or functionally identical elements are provided with the same reference signs.

[0037] Figure 1a Shows a top view of a conventional crown as connecting element according to the prior art with six contact lugs arranged in a star shape with the same height and contact surfaces at the same height . It can be seen that the contact lugs have not yet been bent, but according to Figure 1a The contact lugs already have corresponding curved curved edges. The contact lugs are arranged equidistantly on the contact base and have the same rectangular shape and the same length. For many applications, such as in battery modules of vehicles, these shapes of the crowns are used in combination with corresponding contact elements as electrical and mechanical connection elements.

Abstract

The invention relates to a connecting element for electrical contact with a corresponding contact element of an electrical storage unit, comprising a contact base and at least one first and one secondcontact lug for direct mechanical and electrical contact of the connecting element with a side wall of the corresponding contact element of the electrical storage unit, wherein the contact lugs have,at the upper ends, lead-in ramps for the lead-in of corresponding contact elements of the electrical storage cell, are connected at the lower ends to the contact base, and have inner contact surfacesat the contact lugs of different heights.

Description

technical field [0001] The invention relates to a connection element for making electrical contact with a corresponding contact element of an electrical storage unit, and to a method for producing the corresponding connection element. Background technique [0002] The output voltage of an electrical storage unit, such as an electrochemical cell, can be increased to a desired voltage level by successive connection of individual electrical storage units. For this purpose, the electrical storage unit has contact elements for making electrical and mechanical contacting of the electrical storage unit within the corresponding circuit arrangement and thus supplying the electrical energy storage system with defined electrical power. [0003] One of the fields of use of such electrical energy storage systems is in electric vehicles as the sole electric drive source or in combination with a fossil drive source (eg an internal combustion engine) as a hybrid drive. Other possible areas...
