Connector suitable to hold a busbar in contact with an electrode of a battery, system and method and battery set

A connector configured to hold a busbar in contact with another conductor in a high current power supply system, especially a battery unit with an electrode of a battery or with a further busbar, the connector comprising a clamp,

• the clamp having a transition section connecting
• a first leg arranged at one end of the transition section,
• to a second leg arranged at the opposite end of the transition section,
• the transition section and/or the first leg being elastically deformable,
• the clamp having a first state, in which a reference part of the first leg is distanced from a reference part of the second leg by a first amount,
• the clamp having a second state, in which the reference part of the first leg is distanced from the reference part of the second leg by a second amount that is different from the first amount,
• the transitions section and/or the first leg being further elastically deformed in the second state than in the first state,
• the transition section 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,
• the connector further comprising a spacer, the spacer being moveable between a first position and a second position, the spacer being in contact with a part of the first leg when the clamp is in the second state and the spacer is in the first position,
• wherein the spacer
• is designed to be rotated from the first position into the second position;
• 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;
• or
• is designed to perform a combined rotational and linear movement from the first position into the second position,
• the connector further comprising a casing with an opening for inserting a part of the busbar into the casing, a clearance being arranged in the casing between the opening and a busbar abutment surface on the spacer when the clamp is in the second state and the spacer is in the first position.
