摘要
A unitary metal connector pin formed by a cold heading die has a body with a disc-like expanded portion on a first end thereof which is adapted to engage and retain a first body when the pin is inserted through a first aperture in the first body. On a second, opposed end of the pin are disposed plural spaced flexible fingers each having a respective outwardly projecting, radially expanded portion. The radially expanded portions form a segmented outer ring on the pin capable of first undergoing inward deflection, followed by outward radial expansion for engaging a second body when the fingered end of the pin is inserted through a second aperture in the second body for securely coupling the two bodies together. The cold heading die includes a first stage for forming in a connector pin blank a first hollowed-out end portion with the flexible fingers and a second stage for forming the second radially expanded end portion and the outer projections on the flexible fingers.
