Abstract
Abstract A connector having ESD protection is disclosed having a housing, and a first and second set of connector contacts. First set of connector contacts provide discharge of static charge prior to the engagement of second set of connector contacts. Connector may be adapted to provide protection against static charge transfer in applications ranging from an RJ-45 connector realization to a PCB edge connector application.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
143 words
An electrical connector comprising: a jack housing having an external cavity for receiving a mating plug, said mating plug comprising a plug housing having at least one plug electrical contact, said external cavity having a first position of engagement with said plug housing when said plug is partially inserted in said external cavity, and a final position of engagement with said plug housing when said plug is fully inserted in said external cavity; a first set of jack electrical contacts located in said jack housing and extending into said external cavity and making contact with said plug electrical contacts exclusively during said first position of engagement; a second set of jack electrical contacts located in said jack housing and extending into said external cavity and making contact with said plug electrical contacts exclusively when said plug is in said final position of engagement.
Claim 2
Dependent Claim
143 words
