ABSTRACT:
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 32 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.
