Radial jack

A method for producing an electrical plug-in connector jack, comprising a cylindrical jack sleeve, wherein the jack sleeve has a receiving space in which a cylindrical contact lamination lattice with a plurality of contact laminations extending parallel to one another is inserted, comprising the steps of:

• a. producing an essentially flat sheet-metal part comprising of first and second end sections and a central portion situated between them, wherein the sheet-metal part has two longitudinal side edges which extend, in each case, from the first end section to the second end section, and a transverse side edge which, in each case, delimits one of the first and second end sections,
• wherein in an extension of the longitudinal side edges, two retaining arms project from the transverse side edge of the sheet-metal part, from the first end section, wherein the retaining arms have, at respective free retaining arm ends thereof, a latching lug for engagement in an undercut which, in each case, takes the form of a corresponding recess in the second end section of the sheet-metal part,
• wherein two retaining tabs project from the transverse side edge of the second end section, and
• wherein a first centering element protrudes from the transverse side edge of the first end section and is located between the retaining arms and a second centering element protrudes from the transverse side edge of the second end section and is located between the retaining tabs;
• b. introducing an intended bending point for each of the retaining arms in the respective longitudinal side edge outwardly delimiting the respective retaining arm;
• and
• c. rolling the sheet-metal part to form a cylindrical jack sleeve such that the retaining arms bear against a front side of the retaining tabs on the second end section of the sheet-metal part, so that each of the retaining arms is first sprung or bent outward about the intended bending point thereof until the latching lug thereof springs into the corresponding recess and the first and second centering elements align the first and second end sections.
