Definitions
- the lead wires 40, 42 are passed through the bores 60, 62 and connected to the connection ends of the winding 32 in the free spaces 64, 66 formed between the ring flange 48 and the third section 58.
- the coil former 34 is provided with edge extensions 67 which, as will be described below, serve for guiding and frictionally clamping the lead wires 40, 42.
- the lead wires 40, 42 are passed through a cable duct 90 in the nozzle holder 10, which consists of a central duct section 92 arranged coaxially with the induction coil 30 and two outer duct sections 94, 96, which are designed as narrow bores. These are diametrically opposite and each form an obtuse angle a with the central channel section 92.
- the channel sections 94, 96 open out in the region of recesses 98, 100 in the jacket of the nozzle holder 10.
- Each channel section 94, 96 is sealed to the outside by an O-ring 102 and a plastic plug 104.
- the line wires 40, 42 are connected in a suitable manner to further lines.
- a cylindrical section 120 is attached to section 110 of cable guide body 44, the diameter of which corresponds approximately to the parallel spacing of bores 116, 118. These continue in section 120 as grooves 122, 124 with an approximately semicircular cross-section, which also serve for cable routing.
- the length of the section 120 is dimensioned such that the cable guide body 44 fills most of the central channel section 92.
- two diametrically opposed wall grooves 126, 128 for guiding the lead wires 40, 42 are formed on the inside.
