Abstract
Abstract The shielding plate is particularly suited for optoelectronic transceivers. The shielding plate is a hollow body in the form of a casing and has contact springs which are formed on the hollow body in order to make contact between the hollow body and a metallic structure. Contact springs are formed by projections which are arranged on the end face of the hollow body and are bent back onto the hollow body. As a result, the shielding plate having a chimney-like structure with improved shielding and reduced emission.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
A shielding plate, comprising: a hollow body formed as a casing with a continuous outer wall surface and an end face; and a plurality of contact springs formed as projections on said end face of said hollow body and having free ends bent back through substantially 180° onto said outer wall surface of said hollow body; said free ends of said plurality of contact springs contacting said outer wall surface of said hollow body and forming an electrical contact of low resistance between said plurality of contact springs and said hollow body.
Claim 2
Dependent Claim
92 words
A shielding plate, comprising: a hollow body formed as a casing with a continuous outer wall surface and an end face; and a plurality of contact springs formed as projections on said end face of said hollow body and having free ends bent back through substantially 180° onto said outer wall surface of said hollow body; said free ends of said plurality of contact springs contacting said outer wall surface of said hollow body and forming an electrical contact of low resistance between said plurality of contact springs and said hollow body.
Claim 3
Dependent Claim
18 words
