NOVELTY - The system (100) has a power line system (104) which is provided with one or more cell connectors (116) for electrically conductive connection of cellular terminals of various electrochemical cells. A signal line system (106) has one or more signal lines (152) for electrically conductive connection of a signal source (154) having a signal line connector (144) of the cell contact system. A support element (102) carries the power line system and the signal line system. The signal line connector comprises a connection housing (176) coupled to the support element.    USE - Cell contact system for electrochemical device used as accumulator e.g. lithium ion secondary battery for use in motor vehicle.    ADVANTAGE - The forces affecting the signal line terminal are not transmitted directly on the signal line system. The connection pins are elastically deformable, so that relative movement between the connector housing and signal lines of the signal cable system is possible without transmission of significant forces from the terminal box on the signal lines. The electrically conductive connections between the terminal pins of the signal line connection and the signal lines of signal cable system can be enabled with very little mechanical stress. The reliability and durability of the electrical connection between the signal lines and the connection pins of connector signal line can be improved. The connector pins are designed to be elastically deformable to support the mechanical decoupling between circuit board and signal line connection. The damage to the power line system and the signal line system during transport and assembly of the electrochemical device is prevented.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for manufacturing cell contact system.
