ABSTRACT:
The end caps of an electric current limiting fuse are telescopingly fitted inside the end portion of a housing tube and sealed to the inside wall in at least two spaced-apart locations to isolate an annular space between the outside cylindrical cap surface and the inside cylindrical housing tube surface. A settable adhesive fills the annular space to tightly bond the cap to the housing and to form a strong hermetic seal.
Also disclosed is a method of making the seal described above, including the steps of assembling in telescoping relationship two cylindrical workpieces, providing at least two seals between the pieces to define an annular space between them, injecting a settable adhesive into the annular recess through an injection port in one of the cylinders while bleeding air out through a bleed aperture, and baking to set the adhesive.
