A module connector includes a first connection part and a second connection part that can be electrically conductively connected with the first connection part. The first connection part has a first attachment element and the second connection part has a second attachment element; the first attachment element can be inserted into the second attachment element. Each of the first connection part and the second connection part has a contact protection at a side facing the other connection part. The contact protection has an outer electrically insulating collar and an electrically insulating protection pin surrounded by the outer electrically insulating collar. At least one of the first connection part and the second connection part has a current bridge between the outer electrically insulating collar and the electrically insulating protection pin. The outer electrically insulating collar and the electrically insulating protection pin extend beyond the current bridge.
