Abstract
Abstract In an electrical interconnection assembly of the type which comprises a conductive plate having elongated contacts mounted in respective apertures thereof by means of respective thermoplastic insulating bushings, a removable sleeve is provided for grounding any contact to said plate without damaging the plate, the bushing, or the contact. The sleeve comprises a cylindrical member having a sharpened lead-in edge at a first end, a fluted body portion, and at the other end, a plurality of arcuate fingers shaped to grip said contact when said sleeve is inserted thereover. To ground any contact, the sleeve is slipped over the contact, first end downward, and the lead-in portion is driven between the plate and bushing such that the fluted body portion makes a good connection with the plate and the gripping fingers make a good connection with the contact.
