Verfahren zur Montage eines ersetzbaren elektro-magnetischen Abschirmungsfederstreifens.

摘要

A plug-like conductive shell (10) of an electrical connector includes a peripheral recess (20) therearound in which is disposed a metal strip (50) having a plurality of spring fingers (66,68) for EMI protection upon mating with a receptacle-like conductive shell of a mating connector. The EMI strip (50) is held in place by one or two elastomeric rings (52). A first system includes a ridge (24) in the shell recess bottom (22) and a corresponding formed ridge (60) in the metal strip (50) disposed thereover, with a pair of rings (52) one on each side of the formed ridge (60) securing the strip (50) against axial movement. A second system includes a groove (102) in the shell recess bottom (104) and a corresponding formed ridge (106) in the metal strip (108) disposed therein, defining a corresponding groove (114) within which is disposed a single ring (112), securing the strip (108) against axial movement. The EMI strip (50) is easily assembled to the shell (10) and is easily removable and replaceable, and retrofitting preexisting in-service connectors is possible to replace damaged EMI spring strips even if originally conventionally secured to the shell.
