초록 ▼

A weld stud having a cylindrical section permitting engagement by a stud welding gun, joined by a shoulder on to a threaded shank covered up to the shoulder by a cap nut made of plastics, wherein the cylinder section changes through a chamfer into a shoulder and the cap nut is provided with a resilient lip, which stretches to cover the chamfer when the cap nut is brought into contact with the shoulder. The threaded shank may have a ridge close to the shoulder which engages in a corresponding annular recess inside the cap nut. The cap nut may have a coaxial, preferably conical, projection at its end opposite the lip.

대표청구항 ▼

A weld stud with a protective cap nut which comprises: a weld stud portion having an cylindrical section with a diameter larger than that of said cap nut wherein said cylindrical section can be contacted by gripping jaws of a stud welding gun; an extension with a conical projection located on one side of said cylindrical section to form a subsequent welding point; a shoulder formed with a chamfer located on the other side of said cylindrical section, opposite said extension, the shoulder having a diameter smaller than the diameter of the cylindrical section; and a shank protruding from said shoulder having an externally threaded section and having a ridge axially spaced from the externally threaded section and formed like a thread for engaging an annular recess on the inside of said cap nut; and a plastic cap nut portion having an internally threaded section threadably engaged to said weld stud portion and having a cylindrical body with an inside diameter sized to threadingly engage said threaded shank, a flange located at an open end of said cap nut to which is attached a resilient lip which stretches to cover the chamfer of said stud when the cap nut is brought into contact with said shoulder, the outer diameter of said lip being smaller than that of said cylindrical section of said weld stud; an annular recess inside said cap nut axially spaced from said internally threaded section to engage said ridge on said threaded shank; a conical projection located at a closed end of said cap nut opposite said lip wherein said cap nut is automatically aligned coaxially with the stud welding gun as said projection is embraced by a holding arrangement inside the weld gun; and fins located circumferentially about said body and sized so as not to protrude beyond the outer diameter of said cylindrical section of said stud.
