Electrical connectors that can be used with battery modules, such as battery modules containing one or more electrochemical cells, and that include features for precisely locating electrical conductors engaged with the electrical connectors and/or features for increasing robustness of the electrical connectors to overcurrent conditions. In some embodiments, each electrical connector includes a securing plate having multiple openings for securing the electrical connector to a positive or negative terminal of a battery module. In some embodiments, each electrical connector includes two or more tapering bridges extending between a securing plate and a pair of corresponding crimping clasps that receive corresponding respective current conductors or branches of a single current conductor during use. Electrical systems containing such electrical connectors are also disclosed.

A grounding module with a single-part grounding element is provided in order to ground a plug connector modular frame. The grounding element can be made of a resilient elastic sheet metal in the form of a stamped bent part. The single-part grounding element forms a contact spring with a contact arm for electrically contacting the plug connector modular frame as well as a busbar and a V-shaped clamping spring for connecting a grounding line to the busbar in an electric manner and so as to produce a mechanical fixation.
