Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the following, exemplary embodiments are further elucidated on the basis of the schematic drawings which are not to scale. It is shown in:

[0024] FIG. 1 a side view of an exemplary embodiment of a high voltage connection with a crimped plug connection,

[0025] FIG. 2 a representation of a longitudinal cut of the high voltage connection of FIG. 1 and

[0026] FIG. 3 a magnified representation of a longitudinal cut of a sealing of the high voltage connection of FIGS. 1 and 2.

DETAILED DESCRIPTION

[0027] FIGS. 1 to 3 show a high voltage connection 1 between a first line 2 of a traveling wave tube 3 shown in FIGS. 1 and 2 on the right and a second line 4 of a voltage supply unit 5 for the traveling wave tube 3 shown in FIGS. 1 and 2 on the left.

[0028] As is apparent from FIG. 2, a space flight qualified plug 6 is connected to an end section 7 of the first line 2 by a crimp connection 8, and a space flight qualified socket 9 is connected to an end section 10 of the second line 4 by a crimp connection 11. Plug 6 is stuck into socket 9. The first end section 7 is formed by a first strand 21 of the first line 2, and the second end section 10 is formed by a second strand 22 of the second line 4.

[0029] Plug 6 and socket 9 are shrunk over with a space flight qualified and high voltage resistant shrinking hose 12, e.g., made of polyethylene. Shrinking hose 12 overlaps plug 6 and socket 9 and firmly lies on a first isolation surface 13 of a first isolation 15 of the first line 2 and on a second isolation surface 14 of a second isolation 16 of the second line 4. Opposing end sections 17, 18 of the shrinking hose 12 are sealed with the respective isolation surface 13, 14 of the first line 2 and of the second line 4 by means of an adhesive 19, e.g., on the basis of epoxy resin or polyurethane. For an especially good adhesion of the adhesive 19, the isolation surfaces 13, 14 may be pretreated correspondingly in accordance with known methods.

[0030] Plug 6 and socket 9 are directly shrunk over with a shrinking hose 20 which has low outgas and which is conductive on its inside, and which, in turn, is shrunk over with a space flight qualified and high voltage resistant shrinking hose 12 which overlaps the shrinking hose 20 that is conductive on its inside.

[0031] The first strand 21 is located inside the first isolation 15 and the second strand 22 is located inside the second isolation 16. As especially good apparent from FIG. 3, an end face 23 of the first isolation 15 is sealed by means of an adhesive 24, e.g., on the basis of low outgasing, strain hardening epoxy resin or polyurethane. The adhesive 24 forms a ring-shaped sealing which adheres circumferentially at a section 25 of the first end section 7, which section 25 is adjacent to an end adjacent to the end face 23 as well as axially at the end face 23 and which flares conically in direction of the end face 23. Furthermore, the adhesive 24 has a lower volume conductivity than the first isolation 15 of the first lines 2.

[0032] The shown high voltage connection may be established by first providing the first line 2 of the traveling wave tube 3 and the second line 4 of the voltage supply unit 5. Subsequently, the crimp connection 8 between the plug 6 and the end section 7 of the first line 2 is made. Likewise, the crimp connection 11 between the socket 9 and the end section 10 of the second line 4 is made. Connecting the plug 6 with the socket 7 follows. Subsequently, the plug 6 and the socket 9 are shrunk over with the shrinking hose 20 which is conductive on its inside.

[0033] The end sections 7, 10 with plug 6, socket 9, isolations 15, 16, and the shrinking hose 20 which is conductive on its inside are then heated, and sealing of the end face 23 and of the section 25 by means of the adhesive 24 takes place in the heated state, wherein beforehand a treatment of the surfaces to be moistened with the adhesive 24 was done. Subsequently, it is cooled down to room temperature, wherein the adhesive 24 partially infiltrates the first isolation 15 due to capillary effect where it fills porous sections and cures. Curing takes place at overpressure as to widely reduce the size of possible occurring blows. Subsequently, the shrinking hose 20 which is conductive on its inside is shrunk over with the space flight qualified and high voltage resistant shrinking hose 12.
