clamping the contact shoe in the cavity of the contact shoe holder by acting on the contact shoe holder with at least an external force directed onto the inserted section of the contact shoe; heating the contact shoe to a temperature sufficient to form a bonded connection with the contact shoe holder; and cooling the current collector head formed from the contact shoe and the contact shoe holder. ## Claims ### Claim 1 A method for manufacturing a current collector head for a current collector having an electrically conductive contact shoe and an electrically insulating contact shoe holder, the method comprising: inserting a section of the contact shoe into an outwardly open cavity in the contact shoe holder dimensioned to match the section; clamping the contact shoe in the cavity of the contact shoe holder by acting on the contact shoe holder with at least an external force directed onto the inserted section of the contact shoe; heating the contact shoe to a temperature sufficient to form a bonded connection with the contact shoe holder; cooling the current collector head formed from the contact shoe and the contact shoe holder. ### Claim 2 (depends on 1) The method of claim 1, wherein the action of the external force after completion of heating is maintained for a predetermined time sufficient for permanent stabilization of the bonded connection. ### Claim 3 (depends on 1) The method of claim 1, wherein heating of the contact shoe occurs inductively by an alternating magnetic field. ### Claim 4 (depends on 1) The method of claim 1, wherein heating of the contact shoe occurs by mechanical contact with at least one heated body. ### Claim 5 (depends on 1) The method of claim 1, wherein the cavity in the contact shoe holder has a form of a groove with two parallel longitudinal sides, the length of which is a multiple of a spacing between the sides, and wherein a main direction of the external force lies perpendicular to the longitudinal sides of the groove. ### Claim 6 (depends on 5) The method of claim 5, wherein action of the external force on the contact shoe holder directed onto the contact shoe occurs on one or several individual sites along the groove of the contact shoe holder. ### Claim 7 (depends on 5) The method of claim 5, wherein action of the external force on the contact shoe holder directed onto the contact shoe occurs extensively along the entire groove of the contact shoe holder. ### Claim 8 (depends on 5) The method of claim 5, wherein heating of the contact shoe occurs on a section of the contact shoe protruding from the groove in the contact shoe holder. ### Claim 9 (depends on 5) The method of claim 5, wherein heating of the contact shoe occurs on one or several individual sites along the groove of the contact shoe holder. ### Claim 10 (depends on 5) The method of claim 5, wherein heating of the contact shoe occurs extensively along the entire groove of the contact shoe holder. ### Claim 11 (depends on 6) The method of claim 6, wherein both the action of the external force on the contact shoe holder directed onto the contact shoe, as well as the heating of the contact shoe on an identical site or several identical individual sites occur relative to the longitudinal direction of groove of the contact shoe holder. ### Claim 12 (depends on 9) The method of claim 9, wherein both the action of the external force on the contact shoe holder directed onto the contact shoe, as well as the heating of the contact shoe on an identical site or several identical individual sites occur relative to the longitudinal direction of groove of the contact shoe holder. ### Claim 13 (depends on 1) The method of claim 1, wherein the contact shoe is heated to a temperature sufficient to form a bonded connection between the surfaces of the contact shoe holder pressed together by the clamping force and the contact shoe. ### Claim 14 (depends on 1) The method of claim 1, wherein the electrically insulating contact shoe holder includes a thermoplastic. ### Claim 15 (depends on 1) A current collector head for a current collector, comprising an electrically conductive contact shoe and an electrically insulating contact shoe holder, wherein the current collector head is produced by the method of claim 1. ### Claim 16 (depends on 14) The current collector head of claim 14, wherein the electrically insulating contact shoe holder includes a thermoplastic.
