摘要： An improved electromagnetic interference shield (200) for a module (300) includes springs (202) in which the compression force pushes the springs (202) in a direction that is approximately parallel to the optic axis. The springs (202) allow significantly looser tolerances on the placement of the module (300) on its associated printed circuit board. The shield (200) also includes an opening near its center, the edge of which includes a plurality of teeth (206). When the shield (200) is placed onto the module (300), the teeth (206) bend along the negative optic axis direction and prevent the shield (200) from being pulled away from the module (300). Accidental removal of the shield (200) is thus prevented. The shield (200) splits the enclosure ground from the internal signal ground, decreasing the capacitance between them, in turn decreasing another possible source of electromagnetic radiation. In addition, the shield (200) is more cost efficient to manufacture since it only requires a one step assembly process.
