Abstract

The work described in this paper is concerned with establishing procedures to assess the relative insertability qualities of different dual in line package electronic connectors. The measure of insert-ability chosen for comparison purposes is the maximum allowable post misalignment which will still result in successful pin insertion. An experimental insertion fixture is described which can be adjusted to correspond to different hole sizes, different board thickness and varying amounts of initial pin misalignment. Force measurements made with this insertion fixture are compared with theoretical models of the insertion process developed by the writers. The models differ from those already available in the literature for the post insertion problem in that the primary mechanism of insertion from a misaligned position results from deformation of the post and not from compliant motions of the work fixture or gripper. It is shown that even for small amount of misalignment, significant plastic deformation of the posts usually occurs during insertion. © 1987 CIRP.
