Embodiment Construction

[0040] figure 1 Shown is a device 10 embodied as a bushing through a metal wall 1 , which is welded with a weld seam 2 to the metal wall 1 through which the device 10 is led through. The device 10 has an inner conductor 11 arranged within the tube interior space of a tubular metal sheath 12 and electrically insulated from the tubular metal sheath 12 using a compacted electrical insulating material 13 . The connecting section 11 a of the inner conductor 11 protrudes from the tubular metal sheath 12 and is provided on the end side with a thread introduced into the connecting section 11 a of the inner conductor 11 , on which thread the electrical contact 4 is fixed using a nut 3 . Consequently, the device 10 is subjected to considerable torques M, which must be absorbed by the electrically insulating material 13 , when temporarily used as intended, ie especially when the nuts 3 are tightened with the screw wrench 5 to fix the contacts 4 .

[0041] This is achieved in that the elec...

Abstract

The invention provides a device (10, 20, 30) and a method for manufacturing the device. A device is disclosed with an internal conductor (11, 21, 31), which is arranged within the tube interior of a tubular metal sheath (12, 22a, 22b, 32) and is electrically insulated from this sheath with a compacted, electrically insulating material (13, 23, 33), in which the compacted electrically insulating material is a compacted magnesium oxide granulate made from magnesium oxide grains (14, 24, 34) of different sizes with edges and projections (24a, 34a), and that sections, especially edges and projections of magnesium oxide grains are pressed, under local deformation of the internal conductor and / or the tubular metal sheath, into the internal conductor or into the tubular metal sheath.

Description

technical field [0001] There is a range of devices having an inner conductor arranged within the tube interior space of a tubular metal sheath and electrically insulated from the tubular metal sheath using an electrically insulating material. In particular, these include mineral insulated sheathed pipelines, which have been widely used in various applications, for example as electrical bushings through metal walls. Background technique [0002] Here, it has been shown in practical use that the mechanical stability of such devices is often not yet sufficient for the high demands of many technical environments. When the device is subjected to torsion, tension, impact, pressure and / or vibration to a large extent in use, and / or when the inner conductor is used as a suspension for a structure such as a honeycomb structure used in exhaust gas cleaning systems This is especially the case when installing. Contents of the invention [0003] It is therefore an object of the presen...
