Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
A method of inserting a printed circuit board, having equally spaced conductive patterns on the edge of at least one side of the printed circuit board, into and between equally spaced opposing contact fingers on a printed circuit board edge connector, comprising the steps of; positioning the printed circuit board and card edge connector in a predetermined relation to each other and rotating the printed circuit board between the opposing contact fingers so that the conductive patterns on the edge of the printed circuit board are sequentially inserted between and come into contact with the contact fingers.
Claim 2
Independent Claim
97 words
A method of inserting a printed circuit board, having equally spaced conductive patterns on the edge of at least one side of the printed circuit board, into and between equally spaced opposing contact fingers on a printed circuit board edge connector, comprising the steps of; positioning the printed circuit board and card edge connector in a predetermined relation to each other and rotating the printed circuit board between the opposing contact fingers so that the conductive patterns on the edge of the printed circuit board are sequentially inserted between and come into contact with the contact fingers.
Claim 3
Independent Claim
123 words
A method of joining a card edge connector having two rows of equally spaced opposing contact fingers and a printed circuit board having conductive strips, on the edge of the board, with the same spacing as the opposing contact fingers, comprising the steps of; securing the card edge connector in a fixed position, positioning the printed circuit board in a predetermined position adjacent to the card edge connector, rotating the printed circuit board in a first direction between the opposing contact fingers one conductive strip at a time until each conductive strip is between opposing contact fingers, and rotating the printed circuit board in a second direction to remove the printed circuit board with the card edge connector thereon from said fixed position.
Claim 4
Independent Claim
123 words
A method of joining a card edge connector having two rows of equally spaced opposing contact fingers and a printed circuit board having conductive strips, on the edge of the board, with the same spacing as the opposing contact fingers, comprising the steps of; securing the card edge connector in a fixed position, positioning the printed circuit board in a predetermined position adjacent to the card edge connector, rotating the printed circuit board in a first direction between the opposing contact fingers one conductive strip at a time until each conductive strip is between opposing contact fingers, and rotating the printed circuit board in a second direction to remove the printed circuit board with the card edge connector thereon from said fixed position.
Claim 5
Dependent Claim
26 words
The method according to claim 2 wherein the printed circuit board is rotated about an alignment pin utilizing an indexing hole on the printed circuit board.
Claim 6
Dependent Claim
23 words
The method according to claim 2 including the step of bonding the contact fingers to the conductive strips on the printed circuit board.
Claim 7
Dependent Claim
147 words
A tool for inserting a card edge connector on a printed circuit board having equally spaced conductive areas on the edge of the printed circuit board, the edge connector having two rows of opposing contact fingers having the same spacing as the conductive areas on the edge of the printed circuit board, comprising; a mounting base, means for holding the card edge connector secured to said mounting base, indexing means mounted on said mounting base adjacent to the means for holding the connector for aligning the printed circuit board with the connector such that the printed circuit board can be rotated in one direction to insert, one at a time, the conductive areas on the printed circuit board between the opposing contact fingers of the edge connector, and then rotated in the other direction to remove the edge connector from the means for holding the edge connector.
Claim 8
Dependent Claim
147 words
A tool for inserting a card edge connector on a printed circuit board having equally spaced conductive areas on the edge of the printed circuit board, the edge connector having two rows of opposing contact fingers having the same spacing as the conductive areas on the edge of the printed circuit board, comprising; a mounting base, means for holding the card edge connector secured to said mounting base, indexing means mounted on said mounting base adjacent to the means for holding the connector for aligning the printed circuit board with the connector such that the printed circuit board can be rotated in one direction to insert, one at a time, the conductive areas on the printed circuit board between the opposing contact fingers of the edge connector, and then rotated in the other direction to remove the edge connector from the means for holding the edge connector.
Claim 9
Dependent Claim
130 words
A tool for inserting a printed circuit board, having conductors thereon and an indexing hole therein, into and in alignment with opposing contact fingers on a contact assembly, comprising; a mounting base, a contact assembly holder mounted on and secured to said mounting base, and an alignment pin, said contact assembly holder having a groove extending the length of the contact assembly holder for receiving a contact assembly, said alignment pin extending vertically from the surface of the mounting base adjacent to one end of the groove in the contact assembly holder, whereby a printed circuit board, having an indexing hole, is positioned with the alignment pin in the indexing hole, and is rotated about the indexing pin to insert the circuit board into opposing contacts in the contact assembly.
Claim 10
Dependent Claim
130 words
A tool for inserting a printed circuit board, having conductors thereon and an indexing hole therein, into and in alignment with opposing contact fingers on a contact assembly, comprising; a mounting base, a contact assembly holder mounted on and secured to said mounting base, and an alignment pin, said contact assembly holder having a groove extending the length of the contact assembly holder for receiving a contact assembly, said alignment pin extending vertically from the surface of the mounting base adjacent to one end of the groove in the contact assembly holder, whereby a printed circuit board, having an indexing hole, is positioned with the alignment pin in the indexing hole, and is rotated about the indexing pin to insert the circuit board into opposing contacts in the contact assembly.
Claim 11
Dependent Claim
49 words
The tool according to claim 6 including adjustable means attached to the contact holder assembly and having one part thereof which determines the length of the groove in the contact holder assembly open for receiving a contact assembly to position the contact assembly to accommodate assemblies of different lengths.
Claim 12
Dependent Claim
55 words
The tool according to claim 6 wherein the groove in the contact assembly holder is dimensioned to hold the contact holder in position during the insertion of the printed circuit board while permitting the contact assembly to be rotated out of the groove after the circuit board has been inserted into the opposing contact fingers.
Claim 13
Dependent Claim
37 words
The tool according to claim 6 wherein the location of the alignment pin with respect to the contact assembly is independent of the number of contact fingers in the contact assembly and the spacing between contact fingers.
