Embodiment Construction

[0017] figure 2 The pluggable sleeve 10 shown in includes a sleeve body 12 made of insulating material, and an electrical conductor 14 is inserted into the sleeve body, and the electrical conductor extends to the outside of the sleeve ( figure 2 Middle is the upper) end. The sleeve body 12 has a cylindrical shank section 16 which defines the central axis M and is connected to the shank section with an outer cone 18 whose maximum diameter is smaller than the diameter of the cylindrical shank section 16 . The outer contour of the sleeve 10 therefore has a constriction 20 .

[0018] Arranged within the sleeve body 12 is an electric field control element 22 which surrounds the conductor 14 in the region of the section in which the electric field control element 22 is embedded in the insulating material of the sleeve body 12 .

[0019] Such as figure 2 As shown, in the exemplary embodiment shown, the electric field control element 22 is arranged with most of its axial length...
