Device for connecting a terminal of a battery module to an electrical conductor

A connection device for connecting a terminal of a battery module to an electrical conductor, the connection device comprising:

• a longitudinal insulation body in which the electrical conductor is disposed, the longitudinal insulation body having at least one terminal receiving housing, the longitudinal insulation body having, on a first face, a first opening for insertion of the terminal into the receiving housing and, on a second face opposite the first face, a second insertion opening for insertion of an electrical connector, the second insertion opening opening into the receiving housing;
• and
• a connection arrangement including:
• an electrical connector configured to fit into the second insertion opening and to electrically contact the terminal and the electrical conductor so as to electrically connect them together;
• a latch arranged at least on the second face of the longitudinal insulation body and adapted to move longitudinally between a first latch position in which the second insertion opening is exposed to allow the insertion of the electrical connector, and a second latch position in which the latch at least partially overhangs the second insertion opening to lock the electrical connector in the receiving housing;
• and
• a visual lock indicator disposed on the longitudinal insulation body so as to be at least partially concealed by the latch in the first latch position and fully exposed in the second latch position.
