Abstract
Abstract An ESD protection subassembly for a conductively-case module having an electrical connector mounted thereon, uses a conductive shield shell member formed about the connector and connected to the module conductive case; the shell member has at least one conductive door member mounted thereon by associated hinge formations having spring-like mechanisms for urging the door members to close off an opening in the shell member whenever the module is not mated with an associated receptacle connector. A substantially complete conductive peripheral enclosure is thus formed for the module and its attached connector, whether the module is mounted in a larger assembly with its complementary connector actually mated with the module-mounted connector, or if the module has been removed from the rack assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A shielding subassembly for use with a transportable electronics-containing module having a conductive case with a surface upon which is mounted an electrical connector means which is to be mated to a complementary connector means mounted on a conductive rack separate from said case, comprising: a conductive shell member completely surrounding said connector means, and having an opening through which said complementary connector means must pass to make or break connection with said connector means; said shell member being adapted for sliding telescoped movement around a portion of said case, and including means for maintaining conductive contact between the shell member and the case about which the shell member is sliding; and conductive door means for forming a conductive closure completely across said opening and cooperating with said shell member and said case for completing a conductive envelopment of said connector means and the entire attached module, whenever said complementary connector means is not present in said opening.
Claim 2
Dependent Claim
158 words
A shielding subassembly for use with a transportable electronics-containing module having a conductive case with a surface upon which is mounted an electrical connector means which is to be mated to a complementary connector means mounted on a conductive rack separate from said case, comprising: a conductive shell member completely surrounding said connector means, and having an opening through which said complementary connector means must pass to make or break connection with said connector means; said shell member being adapted for sliding telescoped movement around a portion of said case, and including means for maintaining conductive contact between the shell member and the case about which the shell member is sliding; and conductive door means for forming a conductive closure completely across said opening and cooperating with said shell member and said case for completing a conductive envelopment of said connector means and the entire attached module, whenever said complementary connector means is not present in said opening.
Claim 3
Dependent Claim
19 words
The subassembly of claim 1, wherein the contact means is located on an inner surface of the shell member.
Claim 4
Dependent Claim
67 words
The subassembly of claim 1, further comprising: a fixed member affixed to the case; and spring means connected between said shell member and said fixed member for storing energy when said shell member slides in a first direction during engagement of said complementary connector means and for urging the shell member in a second direction, opposite to said first direction, when said complementary connector means is disengaged.
Claim 5
Dependent Claim
24 words
The subassembly of claim 3, wherein said spring means includes at least one spring member connected between the shell member and the fixed member.
