ABSTRACT:
Disclosed is a method for manufacturing a printed circuit card edge connector having a pull through bellows contact and a lay-over insulator. Manufacturing steps include inserting contacts interconnected by a common support strip into the top openings of sleeves and positioning the projections of those contacts within alignment troughs such that the contact tails extend out of the bottom of the openings in alignment. The common support strip is removed and the tails of the contacts are inserted through apertures arranged in linear arrays through the substrate. Force is applied to the tails rigidly press-fit mounting the contacts to the substrate. Further disclosed are the forming of first and second extending ears as integral portions of the upper contactor and intermediate mounting regions of the contact, respectively, and the forming of alignment tracks configured to receive the first and second ears. Also disclosed are methods of manufacture including the use of inner and outer alignment tracks wherein the first ears are inserted into the outer alignment track and, where the outer alignment track extends through the sleeve from the top to the bottom of the insulative block, applying force to the tails of the contacts and passing the first ears along the outer alignment track. Further disclosure includes receiving the ears in interference engagement within the alignment track and sliding sub-projections in interference engagement with the troughs, retaining the contacts within the insulative block in alignment and slideably positioning the upper contactor region relative to the sleeves and slideably receiving the ears of said contacts in said troughs.
