Claim 9
Independent Claim
107 words
A method of shortening a selected electrical contact, comprising the steps of: inserting multiple electrical contacts along respective contact receiving cavities in an insulating housing of an electrical connector with a selected contact being inserted farther from a mating end of the housing than each other contact, and shortening a rear portion on the selected contact by a bend that is not present in at least one other contact such that a front end of the selected contact remains recessed rearwardly relative to a front end of said at least one other contact while the rear portion of the selected contact is translated to a selected location.
Claim 10
Independent Claim
107 words
A method of shortening a selected electrical contact, comprising the steps of: inserting multiple electrical contacts along respective contact receiving cavities in an insulating housing of an electrical connector with a selected contact being inserted farther from a mating end of the housing than each other contact, and shortening a rear portion on the selected contact by a bend that is not present in at least one other contact such that a front end of the selected contact remains recessed rearwardly relative to a front end of said at least one other contact while the rear portion of the selected contact is translated to a selected location.
Claim 11
Dependent Claim
33 words
A method as recited in claim 7 comprising the steps of: forming the multiple contacts identical with one another prior to the step of inserting the multiple contacts along respective contact receiving cavities.
Claim 12
Dependent Claim
169 words
A method as recited in claim 7 comprising the steps of: forming said initially identical contacts to have first portions insertable into respective said cavities in an interference fit; forming prior to said contact insertion step, right angle bends in all said initially identical contacts and defining contact second portions; and providing a tool for inserting said selected contact wherein said tool includes a relief recess adjacent said right angle bend and aligned with said front end of said selected contact, and said tool further includes a support surface engaging during contact insertion said contact second portion spaced from said right angle bend, whereby, during insertion of said selected contact as said tool engages and supports said contact second portion to urge said contact first portion into said contact receiving cavity, said interference fit urges said right angle bend rearwardly into said tool relief recess such that a front end of said selected contact is spaced rearwardly from front ends of other said initially identical contacts upon full insertion.
Claim 13
