Module connector for electrically connecting to a module pole connection of a battery module, module pole connection and connecting assembly

A module connector for electrically connecting to a module pole connection of a battery module by producing a plug connection in a connecting direction, wherein the module connector comprises:

• an electrically conductive busbar with a busbar through-opening for passing through a fastener in the connecting direction;
• an electrically conductive contact socket having a socket part with an insulation-free end face providing a contact surface for electrically contacting the module pole connection, wherein the contact socket has a socket opening which is arranged below the busbar and coaxially aligned with the busbar through-opening with respect to the connecting direction, so that the fastener can be passed through the busbar through-opening and the socket opening simultaneously in the connecting direction;
• and
• an electrically insulating housing with an insulation collar that surrounds at least a part of the busbar and at least a part of the contact socket in a radial direction;
• wherein the insulation-free socket part of the contact socket, which comprises the end face with the contact surface, protrudes from the housing in the connecting direction,
• wherein the module connector has a slot-like recess on the end face of the contact socket.
