Abstract
An electrical connector assembly having shielded cage assembly with at least one port for receiving modules, and methods of manufacture and use thereof. In one embodiment, the modules comprise SFP-type (small form-factor pluggable) modules, and the shielded cage assembly comprises an EMI shield member that is disposed at a port opening for the electrical connector assembly. In one variant, the EMI shield member can be disposed on the electrical connector cage assembly without the need for secondary processing techniques such as soldering, or resistance welding. This is accomplished via for example the utilization of mechanical snap features.
Claims19
An electrical connector assembly, comprising:
- an insulative housing;
- and
- a shield assembly at least partly enclosing the insulative housing and comprising a body shield member having one or more port openings, and a noise shield member disposed at least partly around the body shield member adjacent the one or more port openings;
- wherein the noise shield member comprises one or more snap features that cooperate with a respective feature on the body shield member, the cooperation obviating a need for one or more secondary processing techniques when disposing the noise shield member around the body shield member;
- and
- wherein at least one of the one or more snap features comprises a generally C-shaped element, the C-shaped element configured to fit substantially around at least a portion of an edge of the body shield member such that the one or more snap features contact both an internal and external face of the noise shield member.
A noise shield member for use on an electrical connector assembly, the noise shield member comprising an attachment feature, the attachment feature comprising:
- a substantially arcuate portion, the substantially arcuate portion extending outward from the noise shield member and configured to house a front edge of a port opening of the electrical connector assembly;
- and
- a protruding portion that extends inward toward the interior of the port opening when the noise shield member and the electrical connector assembly are assembled.
An electrical connector assembly, comprising:
- an insulative housing;
- and
- a shield assembly at least partly enclosing the insulative housing and defining a plurality of port openings, the shield assembly comprising:
- an external shield member;
- a noise shield member disposed about the external shield member and adjacent the plurality of port openings;
- and
- a divider shield member that at least partly separates at least two of the plurality of port openings;
- wherein the noise shield member comprises an attachment feature that cooperates with a respective feature at the port openings defined by the shield assembly to secure the noise shield member to the external shield member;
- and
- wherein the attachment feature comprises a shield receiving portion, the shield receiving portion configured to fit substantially round a front edge that defines at least one of the port openings of the shield assembly.
