Abstract:
A method for fabricating a cylindrical housing for a snap in cable connector from a sheet metal blank comprising:1) stamping the sheet metal blank to form a first cup about 1Â½ inches in diameter and Â¾ of an inch tall; 2) drawing the first cup further to form a second cup about 1 inch tall and 1 inch in diameter; 3) drawing the second cup yet further to form a third cup having a bottom diameter of about {fraction (31/32)} of an inch, a top diameter of about 1&frac18; inches and a height of about 1{fraction (13/32)} inches; 4) drawing the third cup to form a fourth cup having a height of about 1Â¾ inches and a bottom diameter of about {fraction (25/32)} of an inch; 5) drawing the fourth cup to form a fifth cup having a diameter of about Â¾ of an inch with a slight taper toward the bottom of the cup; 6) striking the fifth cup to extend its height about {fraction (1/16)} of an inch and punch out an about {fraction (17/64)} of an inch hole in the bottom thereof to form a first cylinder having a bottom end in the area of said punched out hole and a generally rectangular top end about 1&frac18; inches across; 7) trimming said generally rectangular top end of said fifth cup to form a product cylinder to a generally round end having a {fraction (31/32)} of an inch in diameter with one flat side; 8) striking the product cylinder of step 7 to form A) an approximately 1 inch in diameter peripheral rim having a depth of about {fraction (3/32)} of an inch about the approximate middle third of said cylinder and B) an about {fraction (1/16)} of an inch spherical depression in said bottom end; 9) shortening the product cylinder of step 8 to a height of about 1{fraction (27/64)} of an inch; 10) striking the product cylinder of step 9 to form an approximately {fraction (53/64)} of an inch in diameter by {fraction (3/32)} of an inch thick peripheral ring about the outside of said bottom end; 11) cutting a pair of 180Â° displaced cutouts about &frac38; of an inch long in the wall of the product cylinder of step 10; 12) punching or cutting an access aperture in the wall of the cylinder product of step 11 spaced about 90Â° about the periphery from said cutouts; and 13) punching a {fraction (17/32)} of an inch hole in said cylinder bottom and flattening said cylinder bottom.
