Abstract
A method for producing a connection unit (1) which has a connector with a connector shaft (6) and a disc (3) which is captively arranged on the connector shaft (6). The disc (3) has an annular disc body (23), the inner contour (33) and outer contour (34) of which have been produced by a plastic deformation of the disc body (23). The inner contour (33) is shaped such that the disc body (23) is fixed on the connector shaft (6). At the same time, the originally non-circular outer contour (34) is shaped so as to be at least substantially circular. The deformation process is carried out by introducing radial deformation forces into the outer circumferential surface (27) of the disc body (23).
Claims23
A method for producing a connection unit, wherein the connection unit comprises a connector, said connector being with a connector shank which comprises a connection structure and with a connector head which is arranged on the connector shank and projects radially beyond the connector shank, and wherein the connection unit further comprises an annular disc which comprises a plastically deformable annular disc body and a through-hole which is framed by the annular disc body and through which the connector shank passes, wherein the annular disc body has an outer peripheral surface which defines an outer contour of the disc body and an inner peripheral surface which peripherally delimits the through-hole and defines an inner contour of the disc body, wherein for the captive fixation of the disc which is seated on the connector shank, the inner contour of the disc body in the state of the disc in which it is seated on the connector shank and starting from a preliminary inner contour which permits the prior sticking of the disc onto the connector shank is reshaped by way of plastic reshaping of the disc body into a final inner contour which effects a captive fixed holding of the disc on the connector shank and which differs from the preliminary inner contour, and wherein
- wherein the annular disc body, before its plastic reshaping, is provided with a preliminary outer contour which differs from a circular shape, and is put onto the connector shank,
- and wherein the plastic reshaping of the annular disc body which creates the final inner contour of the annular disc body is carried out by way of radial deformation forces being introduced into the outer peripheral surface which has the preliminary outer contour, of the disc body which is seated on the connector shank,
- wherein the plastic reshaping of the annular disc body is designed such that the final inner contour of the annular disc body differs from a circular shape and simultaneously a final outer contour of the disc body which differs from the preliminary outer contour and which is at least essentially circular is also shaped.
A connection unit, with a connector which comprises a connector shank which is provided with a connection structure and a connector head which is arranged on the connector shank, wherein the connector head projects radially beyond the connector shank, and with an annular disc which comprises an annular disc body which consists of a plastically deformable material and which frames a through-hole through which the connector shank passes, said through-hole being peripherally delimited by an inner peripheral surface of the disc body which defines an inner contour of the disc body which is produced by the plastic material reshaping of the disc body, wherein this inner contour is designed such that the disc, by way of interaction with the connector shank, is captively held on the connector shank, and wherein the annular disc body has an outer peripheral surface which defines an outer contour-O of the disc body, and
- wherein the annular disc body is designed as a reshaping part, wherein the inner contour is based on a radial plastic reshaping of the disc body, said disc body being provided in a holed form and said reshaping having been created by the introduction of radial deformation forces into the outer peripheral surface of the disc body, and
- wherein the outer contour of the annular disc body is designed at least essentially circularly, and
- wherein the inner contour of the annular disc body is designed in a non-circular manner.
