Claim 13:
14. An RJ jack comprising:
a jack housing;
an opening formed in the jack housing adapted to accept an RJ plug;
a latch catch formed on a first side within said opening of said jack housing to retain a latch of the RJ plug; and
a plurality of contact terminals formed on a second side within said opening of said jack housing, each contact terminal formed to make electrical contact with a corresponding conductive blade of the RJ plug,
wherein said plurality of contact terminals includes at least two primary contact terminals which have first engagement portions positioned at least a first distance from a plane of said opening, wherein said first engagement portions of said at least two primary contact terminals are the last portions of said at least two primary contact terminals to make electrical contact with corresponding blades of the RJ plug upon removal of the RJ plug from said opening,
wherein said plurality of contact terminals includes a secondary contact terminal having a second engagement portion which is positioned at a second distance, less than said first distance, from said plane of said opening, wherein said second engagement portion of said secondary contact terminal is the last portion of said secondary contact terminal to make electrical contact with a corresponding blade of the RJ plug upon removal of the RJ plug from said opening, and
wherein said plurality of contact terminals includes a tertiary contact terminal having a third engagement portion which is positioned at a third distance, less than said second distance, from said plane of said opening, wherein said third engagement portion of said tertiary contact terminal is the last portion of said tertiary contact terminal to make electrical contact with a corresponding blade of the RJ plug upon removal of the RJ plug from said opening, wherein during removal of the RJ plug from said opening, said third engagement portion of said tertiary contact terminal breaks electrical contact with its corresponding blade of the RJ plug after electrical contact has been broken between said second engagement portion of said secondary contact terminal and its corresponding blade of the RJ plug, wherein said second engagement portion of said secondary contact terminal breaks electrical contact with its corresponding blade of the RJ plug after electrical contact has been broken between said first engagement portions of said at least two primary contact terminals and their corresponding blades of the RJ plug, wherein said first engagement portions and said third engagement portion are formed of a first material and said second engagement portion is formed of a second material different from said first material, and wherein said second material resists damage from sparks or arcs better than said first material.
