Composite clamping shell for electric cigar lighters |
摘要 |
A composite clamping shell for securing the socket of an electric cigar lighter to a panel of an automobile, has a rolled sheet-metal body of tubular shape, with open ends and a clinched seam. Attached to the body is a drawn, sheet metal sleeve having a rolled screw thread. The body has inwardly displaced stop shoulders to position the sleeve, which latter has an annular out-turned flange abutting the stop shoulders. Edge portions of the body end are laid over the out-turned flange of the sleeve to hold it captive and prevent relative movement. The body is stamped out of a piece of flat sheet metal stock and thereafter rolled into the desired cylindrical shape. The sleeve is produced by drawing operations, from flat stock. Reduced manufacturing cost is thus realized.
