• the plug-in element 3 is defined by being the part of the plug body 1 which is intended to be plugged into an opening in a wall. Plug head 2 and 3 plug element must be structurally not clearly separated from each other.
• An electrical line 4 runs through the interior of the plug body 1 from the plug head 2 to the plug element 3, where it ends in an electrical contact 5.
• a Garrungsausnaturalung 6 is formed for attachment of the external cable.
• the plug-in element 3 is of cylindrical symmetry and has a projecting support element 7, which rests on a wall 8, which is shown in section and belongs to a gear cover.
• the wall 8 is part of a housing cover of a gearbox and is preferably made of metal. Between the wall 8 and the support member 7 extends a sealing ring 9 which is fixed to the support element 7.
• a thread with a plurality of spiral-shaped projections 10 is formed on the plug-in element 3.
• the sealing ring 9 is shown in section, so that it does not partially cover the thread.
• the thread of the plug body 1 is screwed into an opening (see FIG. In this case, the helical projections 10 are inserted into recesses 11 located at the edge of the opening. Due to the cylindrical shape, the plug-in element 3 is always at the edge of the opening during insertion and is thus firmly positioned.
• a nose 12 is formed, which has a parallel to the edge of the recess 11 extending edge.
• the position of the nose 12 is chosen so that the contacts 5 are correctly positioned as soon as the nose 12 is completely in the recess 11. A further screwing in of the plug is then blocked by the support element 7. In this case, the sealing ring 9 is strongly compressed, so that the plug is well sealed, as is required for a windscreen wiper motor.
• the nose 12 When screwing in the plug 1, the nose 12 is printed against the wall 8. The wall 8 then yields elastically (this will be explained in more detail with reference to FIG.2) and returns behind the nose 12 back to its original position.
• the nose 12 hooks with the wall 8 and prevents the turning out of the plug 1.
• the pitch of the spiral projection 10 can be chosen so small and matched to the size of the recess 11 that the spiral projection 10 against the wall 8 prints. Then, however, the slope of the protrusion at the location first inserted into the recess should be steeper to facilitate screwing the protrusion under the wall 8.
• the helical projection is then completely screwed into the recess and the wall 8 returns behind the helical projection 10 to its original position.
• the end of the helical projection thus replaces the nose 12.
• the engagement of the plug element 3 and the wall 9 thus means in concrete terms that the helical projection 10 or a nose 12 attached to the helical projection 10 is located at the edge of the recess 11 is applied.

• the plug element 17 is in an opening inserted in the wall 19 and not screwed and is located at the edge of the opening, which is adapted to the rectangular shape of the male member 17, that is also rectangular. Due to its rectangular cross section, the plug element 19 is not only fixedly positioned in the opening, but also can not be twisted. However, the cross section may also be circular, as with reference to FIG. 5 will be explained.
• a recess 21 Parallel to the wall 19 extends on the male member 17, a recess 21. This may extend through the middle of the male member 17, but will preferably be formed at the edge where no electrical lines 4 extend.
• the recess 21 is positioned so that without a force-acting through which a seal 20, which is between the wall 19 and the support member 18 and is attached to the support member 18 is printed together, the recess 21 is not flush to the wall 19 connects, but a step between the wall 19 and the recess 21 is formed.
