CONNECTOR SUITABLE TO HOLD A BUSBAR IN CONTACT WITH AN ELECTRODE OF A BATTERY, SYSTEM AND METHOD AND BATTERY SET

Connector (3) suitable to hold a busbar (4) in contact with another conductor in a high current power supply system, in particular a battery unit, in particular with an electrode (5) of a battery or with a further busbar (4), the connector (3) comprising a clamp (11), • the clamp (11) having transition section (20) connecting • a first leg (22) arranged at one end of the transition section (20), • to a second leg (23) arranged at the opposite end of the transition section (20), • the transition section (20) and/or the first leg (22) being elastically deformable, • the clamp (11) having a first state, in which a reference part (24) of the first leg (22) is distanced from a reference part (25) of the second leg (23) by a first amount, • the clamp (11) having a second state, in which the reference part (24) of the first leg (22) is distanced from the reference part (25) of the second leg (24) by a second amount that is different from the first amount, • the transitions section (20) and/or the first leg (22) being further elastically deformed in the second state than in the first state, • the transition section (20) having a width in a width direction that extends at an angle to a line that connects the one end with the opposite end of the transition section (20), the connector further comprising a spacer (12), the spacer (12) being moveable between a first position and a second position, the spacer (12) being in contact with a part of the first leg (22) when the clamp (11) is in the second state and the spacer (12) is in the first position, characterized in that the spacer (12) • is designed to be rotated from the first position into the second position or • is designed to be moved linearly from the first position into the second position along a retraction direction, the retraction direction pointing at least partially in the width direction and/or at least partially pointing towards the transition section (20) or • is designed to perform a combined rotational and linear movement from the first position into the second position.
