Abstract
Electrical bushing, in particular for pressure applications, with a housing with at least one housing passage and with at least one electrical conductor, which is passed through the housing passage, protrudes at both ends on two housing sides, which are spaced apart from one another, out of in each case one opening of the housing passage out of the housing and is fixed in the housing by means of a tightly sealing material which fills at least the majority of the housing passage.
Claims34
An electrical bushing, for pressure applications, comprising a housing with a housing passage extending at least between two housing sides at a distance from one another, at least one electrical conductor leading through the housing passage and embedded and fastened in a material that fills and tightly seals the housing passage wherein the housing passage comprises on a first housing side at least one first opening, which is provided on a section of a housing periphery extending around a housing axis (L), and the housing passage comprises at least one second opening on a second housing side, and wherein the at least first opening is oriented with an axis radial to the housing axis (L).
A method for manufacturing an electrical bushing for pressure applications, comprising a housing with at least one housing passage, at least one electrical conductor extending through the housing passage and protruding at both ends from the housing from a respective opening of the housing passage on two housing sides at a distance from one another, said at least one electrical conductor being embedded and fastened in a material that forms a glass body and fills and tightly seals the housing passage whereby the housing being provided with the at least one housing passage, which is formed by at least one second bore or bore hole extending in a housing axis (L), and by at least one first bore hole opening into said second bore or bore hole and executed radially or essentially radially to the housing axis (L), by inserting the at least one conductor made of an electrically conductive material so that the conductor is accommodated with a partial length in the second bore or bore hole and with a further angled partial length in the first bore or bore hole, by inserting at least one glass bead in the holes, respectively and by melting the glass beads to form the glass body.
