Patent ID: 7537466

Claim:
Plug ( 1 ) comprising a bushing ( 2 ) and an insulating body ( 3 ) arranged in the position of use in the bushing ( 2 ), and also with elongated contacts ( 4 ), which are held in perforations or boreholes ( 6 ) of the insulating body that extend in an axial direction, wherein one of the contacts is arranged as a ground contact ( 5 ) parallel to other ones of the contacts ( 4 ) within one of the perforations or boreholes ( 6 ), which has a lateral opening ( 8 ) for an electrically conductive retainer spring ( 9 ) that fixes the ground contact ( 5 ) in the position of use in the perforation or borehole ( 6 ), the retainer spring ( 9 ) has a plug-in part ( 10 ), which allows passage in an axial direction and which is arranged in the position of use within the one of the perforations or boreholes ( 6 ) of the insulating body ( 3 ) and has an open inner cross section that corresponds approximately to an outer cross section of the ground contact ( 6 ) which is generally pin-shaped and which is located in the position of use within the insulating body ( 3 ) in alignment with or coaxial to the one of the openings or perforations ( 6 ) of the insulating body ( 3 ) for the ground contact ( 5 ), so that the ground contact can be plugged in during the insertion into the perforation or borehole ( 6 ) for the ground contact in the plug-in part ( 10 ), and the plug-in part ( 10 ) of the retainer spring ( 9 ) fits and is insertable through the lateral opening ( 8 ) in a direction perpendicular to the perforations or boreholes ( 6 ) of the insulating body ( 3 ) and carries at least one spring arm ( 11 ), which extends in the axial direction on an outside thereof and which has, on a free end of the spring arm ( 11 ) projecting past the plug-in part ( 10 ), a projection ( 12 ) that is directed inwardly in a radial direction and that extends into a plug-in path of the ground contact ( 5 ) and acts on the ground contact ( 5 ) in the position of use in a fixing manner, and the ground contact ( 5 ) has, at the position acted upon by the projection ( 12 ) of the spring arm ( 11 ), a recess or depression ( 7 ) and a pivot path of the spring arm ( 11 ) corresponds at least to an engagement depth of the projection ( 12 ) into the recess or depression ( 7 ).
