专利汇可以提供Method of making electrical penetrant structure专利检索，专利查询，专利分析的服务。并且An electrical penetrant structure, and a method of making the same, are disclosed for feeding sealingly one or more electrical conductors through a wall, such as the containment vessel wall in a nuclear-powered electrical generating station.，下面是Method of making electrical penetrant structure专利的具体信息内容。
1. The method of making an electrical penetrant structure, comprising the steps of arranging an incompressible metal conductor in a non-central hole extending longitudinally through an elongated body of resilient insulating material, arranging a tubular metal housing over said body, said housing having an external annular groove having a radial depth equal to at least one quarter of the wall thickness of said housing and an axial length at least equal to half the transverse dimension of the exterior of the ungrooved portion of said housing beFore swaging and swaging such assembly of conductor, body and housing at least for the length of said groove, the clearances between said conductor and body and between said body and housing prior to swaging being such that after swaging the cross-sectional area of said body has been reduced at least ten percent, whereby the transverse dimension of the exterior of said housing after swaging is substantially the same for both those portions originally provided and unprovided with said groove and said conductor is laterally offset toward the portion of the housing wall that had been grooved.
2. The method according to claim 1, wherein said housing is shorter in length than said body of insulating material.
3. The method according to claim 1, wherein one such groove is provided in said housing adjacent each end thereof and the outer end of each groove is arranged axially inwardly from the adjacent outer end of said housing a distance at least equal to the transverse dimension of the exterior of the ungrooved portion of said housing prior to swaging.
4. The method according to claim 1, wherein one such groove is provided in said housing adjacent each end thereof, and one such body of insulating material is provided at each groove, whereby after swaging a space is left between the opposing ends of such bodies of insulating material.
5. The method according to claim 1, wherein one such groove is provided in said housing adjacent each end thereof and an attaching bracket is welded to said housing intermediate such grooves prior to swaging and prior to placement over said body, and each portion of the assembly including one such groove is swaged.
