Abstract
An improved EMI shield assembly for transceivers is provided in the form of a metal shielding cage that has interengaging cover and base portions. The cover portion has two sidewalls that include leading edges that flare outwardly so that the cover portion sidewalls ride up and over the sidewalls of the base portion. Catches are formed in the base portion sidewalls that have curved surfaces which engage the flared portions to further facilitate the assembly of the shielding cage assembly.
Claims20
A shielding cage for a transceiver, comprising:
- an elongated body portion for mounting to a circuit board, the body portion including a plurality of walls that cooperatively define a channel extending longitudinally of said body portion, said body portion including a bottom wall and two sidewalls extending upwardly from the bottom wall, said body portion having a plurality of mounting pins formed therewith and extending therefrom, the mounting pins being received within mounting holes in said circuit board when said body portion is mounted to said circuit board, said body portion sidewalls including a plurality of retainer elements integrally formed therein, said retainer elements including arcuate engagement surfaces that are curved in a horizontal direction along said body portion sidewalls, the arcuate engagement surfaces extending outwardly with respect to said body portion sidewalls;
- an elongated cover portion for covering said body portion channel, the cover portion including a top wall and two sidewalls spaced apart from each other and extending downward therefrom, the cover portion sidewalls having height dimensions which are less than corresponding height dimensions of said body portion sidewalls such that parts of said cover portion sidewalls overlie said body portion sidewalls when said cover portion is applied to said body portion, said cover portion further including a plurality of slots aligned with said body portion retainer elements, the slots being larger in size than said retainer elements such that said retainer elements are captured within said slots when said cover portion is fully engaged on said body portion, said cover portion sidewalls including leading edge portions which are flared outwardly with respect to said cover portions sidewalls, said leading edge portions directing said cover portion sidewalls over said body portion sidewalls when said cover portion is applied to said body portion.
A shielding cage for shielding an electronic component contained therein from electromagnetic interference, comprising:
- an elongated body member for mounting the cage to a surface of a circuit board, the body member including a bottom wall and two sidewalls extending upwardly therefrom and terminating in free ends, the bottom and sidewalls cooperatively defining a channel extending longitudinally through said body member, the sidewall free ends defining two spaced apart leading edges of said body member, said body member including a plurality of pin members extending therefrom which are received within mounting holes disposed in a circuit board when said body member is mounted to said circuit board;
- and,
- an elongated cover member for closing off a top of said body member channel, the cover member and said body member cooperatively defining a hollow receptacle for receiving at least one electronic component therein, said cover member including a top wall and two sidewalls disposed along opposite sides of said cover member top wall and extending downward therefrom, said cover member sidewalls terminating in downwardly extending free ends, said free ends including flared leading edges that extend outwardly relative to both said body member sidewalls and said cover member sidewalls, said flared leading edges, facilitating engagement of said cover member to said body member by riding up said body member leading edges and over said body member sidewalls when said cover member is applied to said body member.
