- a tensile force of 900 N +/- 20 N is achieved according to the standard, which can be maintained even over a minute and ensures a mobility of less than one millimeter.
- a higher current carrying capacity is achieved because no mobility in the axial direction is possible because of the positive connection between the

- Thread forming rib is formed, which protrudes from the inside of the sleeve sheath of the connection cap.
- a thread sufficient to form a relatively far projecting from the sleeve shell rib. If several threads are provided, which forms correspondingly protruding ribs, the ribs do not have to protrude so far, in order nevertheless to achieve and ensure the positive connection between the connection cap and the insulation.
