Environmental seal and alignment means for an electromagnetically formed backshell
First Claim
1. An article of manufacture comprising:
- a hollow cylindrical metal tube;
a cylindrical member of outer diameter less than the tube inner diameter, said member having end portions received within an end of the tube and uniformly spaced from facing tube inner wall surfaces, said member further having a radially outwardly extending flange lying directly opposite and spaced from the member end portions;
an annular resilient seal of generally L-shaped cross-section located between both the tube inner wall surfaces and member end portions and between and in contact with the tube end and the member flange;
said metal tube being magnetically clamped onto the member end portions over the seal compressing the same.

Abstract
A cylindrical rubber or elastomeric gasket which is L-shaped in cross-section having an outwardly extending rim or flange is initially located between a cylindrical backshell and a connector part which the backshell is to be magnetically clamped. The internal diameter of the seal closely approximates the major diameter of the connector part. The backshell end is slid onto the connector part and, more particularly, onto and over the seal with the seal flange extending around the end of the backshell with its outermost surface abutting against a flange on the connector part. The seal in this way accomplishes both aligning of the backshell with the axis of the connector part for the electromagnetic forming step and, as well, effects environmental sealing after the backshell is fully in place.

2. A method of electromagnetically deforming a metal shell into clamping engagement with a cylindrical member having an end portion received within an open end of said shell, said member having an outwardly directed flange on its peripheral surface spaced inwardly from the member end portion, comprising the steps of:
-
locating a resilient non-metallic annular seal about the cylindrical member end portion and abutting against the flange, said seal having a first diametral portion which closely approximates the inner cross-sectional dimensions of the shell and a second diametral portion larger than the first diametral portion, said second diametral portion extending between the shell end and the flange; positioning the shell on the first diametral portion of the seal; aligning an annular magnetic field concentrator on the shell directly opposite the cylindrical member end portion; and energizing the magnetic field concentrator to clampingly deform the shell and compress the seal causing it to expand against the cylindrical member end portion and flange. - View Dependent Claims (3, 4)
