Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
174 words
A method of securing a coil carrying bobbin to a printed circuit board having conductors thereon, said bobbin having a pair of integral post-like extensions of a length to pass through apertures having copper linings in said board and each of said extensions having a pair of opposed grooves therein for accommodating one or the other end of a coil wire, comprising the steps of placing one end of the coil wire into one of the grooves and across the tip of one extension and into the other groove therein, placing the other end of the coil wire into one of the grooves and across the tip of the other extension and into the other groove therein, inserting the extensions with the ends of the coil wire in the grooves thereof into the apertures in said board, and soldering the wired tips of the extensions for securing thereof to the copper linings in the apertures in said board and for connecting the ends of the coil wire to the respective conductors of said board.
Claim 2
Independent Claim
174 words
A method of securing a coil carrying bobbin to a printed circuit board having conductors thereon, said bobbin having a pair of integral post-like extensions of a length to pass through apertures having copper linings in said board and each of said extensions having a pair of opposed grooves therein for accommodating one or the other end of a coil wire, comprising the steps of placing one end of the coil wire into one of the grooves and across the tip of one extension and into the other groove therein, placing the other end of the coil wire into one of the grooves and across the tip of the other extension and into the other groove therein, inserting the extensions with the ends of the coil wire in the grooves thereof into the apertures in said board, and soldering the wired tips of the extensions for securing thereof to the copper linings in the apertures in said board and for connecting the ends of the coil wire to the respective conductors of said board.
Claim 3
Dependent Claim
43 words
The method of claim 1 wherein said bobbin includes a plurality of raised portions on one end thereof for engaging with and seating on one surface of said board and leaving a space between said one bobbon end and said one board surface.
Claim 4
Dependent Claim
42 words
The method of claim 1 wherein the bobbin is generally rectangular in shape and said post-like extensions are located on corners of the bobbin for accommodating the ends of the coil wire in the assembly of the bobbin and the circuit board.
Claim 5
Dependent Claim
49 words
The method of claim 1 wherein the bobbin is generally rectangular in shape and the post-like extensions are located substantially along the centerline of and on the ends of the bobbin for accommodating the ends of the coil wire in the assembly of the bobbin and the circuit board.
Claim 6
Dependent Claim
107 words
A solenoid coil arrangement comprising a substrate having a plurality of copper-lined apertures therethrough, conductive material on one surface of the substrate and individually associated with the apertures, a coil carrying member having posts integral therewith and extending from one end thereof and positioned to be inserted into the apertures in the substrate, said posts having a pair of opposed grooves therein for accommodating the end of a coil wire in the grooves on the sides of each post and across the tip thereof, and means for fusing the end of the coil wire with the copper lining of each aperture and with the respective conductive material.
Claim 7
Dependent Claim
107 words
A solenoid coil arrangement comprising a substrate having a plurality of copper-lined apertures therethrough, conductive material on one surface of the substrate and individually associated with the apertures, a coil carrying member having posts integral therewith and extending from one end thereof and positioned to be inserted into the apertures in the substrate, said posts having a pair of opposed grooves therein for accommodating the end of a coil wire in the grooves on the sides of each post and across the tip thereof, and means for fusing the end of the coil wire with the copper lining of each aperture and with the respective conductive material.
Claim 8
Dependent Claim
21 words
The arrangement of claim 5 wherein said substrate is a printed circuit board for carrying a plurality of coil carrying members.
Claim 9
Dependent Claim
18 words
The arrangement of claim 5 wherein said conductive material comprises runs of copper terminating at the individual apertures.
Claim 10
Dependent Claim
31 words
The arrangement of claim 5 wherein said coil carrying member comprises a generally rectangular-shaped bobbin having shaped posts substantially along the centerline thereof for accommodating the ends of the coil wire.
Claim 11
Dependent Claim
107 words
The combination of a printed circuit board having a plurality of copper-lined apertures therethrough and conductive material on the surface of the circuit board and individually and operably associated with the copper lining of the apertures, and a wire coil carrying member having a pair of posts integral therewith and extending through the apertures and having a pair of opposed grooves along the sides of the posts for accommodating the ends of the coil wire wherein the wire is placed within the grooves and across the tip of the respective post and exposed to enable soldering thereof with the copper lining for connection with the conductive material.
Claim 12
Dependent Claim
107 words
The combination of a printed circuit board having a plurality of copper-lined apertures therethrough and conductive material on the surface of the circuit board and individually and operably associated with the copper lining of the apertures, and a wire coil carrying member having a pair of posts integral therewith and extending through the apertures and having a pair of opposed grooves along the sides of the posts for accommodating the ends of the coil wire wherein the wire is placed within the grooves and across the tip of the respective post and exposed to enable soldering thereof with the copper lining for connection with the conductive material.
Claim 13
Dependent Claim
27 words

Claim 14
Dependent Claim
51 words
The combination of claim 10 wherein said bobbin includes a plurality of raised portions on one end thereof for engaging with and seating on one surface of the circuit board and substantially encircling said apertures and providing a space between said one bobbin end and said one surface of the board.
Claim 15
Dependent Claim
27 words
The combination of claim 9 wherein the wire coil carrying member comprises a generally rectangular shaped bobbin and the posts are positioned on ends of the bobbin.
