AI Technical Summary

Technical Problem

Existing electrical bushings for enclosures, such as those used in electric compressors, are material-intensive and require complex forming processes, leading to significant waste and reduced bending stiffness, while also posing challenges in achieving hermetic seals.

Method used

The design of an electrical feedthrough with a base body having a length greater than its width and thickness, aligned fiber orientation parallel to the longest side, and rounded or chamfered edges, which allows for efficient material use and improved bending stiffness, and incorporates a fixing material for hermetic sealing.

Benefits of technology

This design minimizes material waste, enhances bending stiffness, and ensures hermetic seals with reduced tooling requirements, maintaining mechanical stability and preventing damage during handling.

Abstract

An electrical bushing (2) is provided, comprising a base body (10) with at least one opening (12) and an electrical conductor (30) passing through the opening (12), wherein the conductor (30) is held in the opening (12) by a fixing material (20) and the fixing material (20) seals the opening (12), and wherein the base body (10) has a shape with a longitudinal side of length L, a transverse side of width D and a thickness D, where the length L is greater than the width B and the width B is greater than the thickness D. Furthermore, it is provided that the base body (10) is made of a metal material whose fiber orientation (16) is aligned parallel to the longitudinal side and that the base body (10) is provided, at least along the edges of the longitudinal side, with a rounding (18) having a radius r in the range of 0.5 mm to 2 mm.
