Abstract
Abstract A tool is shown into which two rows of aligned contacts may be inserted. The contacts are connected at one end to a selvedge strip that may be cut to a given length to include a predetermined number of contacts. An insulator housing mounts upon the tool and around the contacts to form a preassembled connector. The housing also functions as a support and guide for the contacts as they are inserted into apertures in a printed circuit board.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A method for preassembling an electrical connector for mounting upon a printed circuit board, comprising the steps of: loading a plurality of contacts into a preassembly tool to form at least one row of aligned contacts; placing an insulator housing upon said preassembly tool about said plurality of aligned contacts to preassemble said connector; and pushing said preassembly tool down against said printed circuit board for placing the said preassembled connector upon said board by inserting said aligned contacts into apertures in said board wherein said contacts hold said insulator housing against said board.
Claim 2
Independent Claim
94 words
A method for preassembling an electrical connector for mounting upon a printed circuit board, comprising the steps of: loading a plurality of contacts into a preassembly tool to form at least one row of aligned contacts; placing an insulator housing upon said preassembly tool about said plurality of aligned contacts to preassemble said connector; and pushing said preassembly tool down against said printed circuit board for placing the said preassembled connector upon said board by inserting said aligned contacts into apertures in said board wherein said contacts hold said insulator housing against said board.
Claim 3
Dependent Claim
52 words
A method for preassembling an electrical connector as claimed in claim 1, including the additional steps of: cutting selvedge strips that support a predetermined number of said contacts to desired lengths; and loading at least two precut selvedge strips supporting said contacts into said preassembly tool to form facing rows of contacts.
Claim 4
Dependent Claim
40 words
A method for preassembling an electrical connector as claimed in claim 2, including the further steps of: pulling said preassembly tool up from said printed circuit board to release said preassembled connector; and removing said selvedge strips from said contacts.
Claim 5
Independent Claim
185 words
A method for preassembling an electrical connector for mounting upon a printed circuit board, comprising the steps of: cutting a selvedge strip supporting a plurality of parallel contacts from one end thereof to a desired length; loading said precut length of selvedge strip-supported contacts into a preassembly tool; cutting a second length of a selvedge strip supporting a like number of parallel contacts; loading said second length of selvedge strip-supported contacts into said preassembly tool; placing an insulator housing upon said preassembly tool about said loaded first and second rows of contacts to preassemble said connector; aligning said printed circuit board under said preassembled connector having at least two rows or apertures therein corresponding in number to and aligned with said first and second rows of loaded contacts; pushing said preassembly tool and said preassembled connector therein against said printed circuit board for securing said contacts within said apertures in said board and said housing thereon; removing said preassembly tool; and removing said selvedge strips from said first and second rows of contacts, thereby leaving said preassembled connector in place upon said printed circuit board.
Claim 6
Independent Claim
185 words
A method for preassembling an electrical connector for mounting upon a printed circuit board, comprising the steps of: cutting a selvedge strip supporting a plurality of parallel contacts from one end thereof to a desired length; loading said precut length of selvedge strip-supported contacts into a preassembly tool; cutting a second length of a selvedge strip supporting a like number of parallel contacts; loading said second length of selvedge strip-supported contacts into said preassembly tool; placing an insulator housing upon said preassembly tool about said loaded first and second rows of contacts to preassemble said connector; aligning said printed circuit board under said preassembled connector having at least two rows or apertures therein corresponding in number to and aligned with said first and second rows of loaded contacts; pushing said preassembly tool and said preassembled connector therein against said printed circuit board for securing said contacts within said apertures in said board and said housing thereon; removing said preassembly tool; and removing said selvedge strips from said first and second rows of contacts, thereby leaving said preassembled connector in place upon said printed circuit board.
Claim 7
Dependent Claim
86 words
Apparatus for preassembling an electrical connector for mounting upon a printed circuit board having apertures therein, comprising: means for retaining a plurality of contacts in at least one aligned row; means for retaining an insulator housing in a preassembled connector configuration about said row of aligned contacts on said means for retaining said contacts; and means for inserting said contacts in said preassembled connector into at least one aligned row of said apertures in said printed circuit board for completing the assembly of said pressembled connector.
Claim 8
Dependent Claim
