Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A coil form comprising a center winding leg over which a coil is to be wound, at least one end plate on an end of said winding leg, terminal board means attached to said end plate and extending outwardly therefrom, said terminal board means including at least one terminal mounting platform extending generally transverse to said end plate and having an accessible bottom portion, an electrical terminal adjacent the top of said terminal mounting platform, said terminal comprising a coil of at least one turn of electrically conductive wire having an arm extending from one end thereof, at least one opening in said platform, an arm of said terminal extending through a said opening to mount the terminal to said platform.
Claim 2
Dependent Claim
121 words
A coil form comprising a center winding leg over which a coil is to be wound, at least one end plate on an end of said winding leg, terminal board means attached to said end plate and extending outwardly therefrom, said terminal board means including at least one terminal mounting platform extending generally transverse to said end plate and having an accessible bottom portion, an electrical terminal adjacent the top of said terminal mounting platform, said terminal comprising a coil of at least one turn of electrically conductive wire having an arm extending from one end thereof, at least one opening in said platform, an arm of said terminal extending through a said opening to mount the terminal to said platform.
Claim 3
Dependent Claim
37 words
A coil form as in claim 1, wherein said terminal board means includes at least a pair of walls also extending generally transverse to said end plate, said walls defining at least a portion of a compartment.
Claim 4
Dependent Claim
21 words
A coil form as in claim 2, wherein there is a said wall on each side of a terminal mounting platform.
Claim 5
Dependent Claim
234 words
Electrical apparatus comprising first and second coil forms each having a center leg on which a coil of wire is wound and an end plate on an end of each such leg; a respective terminal board means extending outwardly from said end plate of each coil form, each said terminal board means including at least a pair of elongated walls spaced apart and extending generally transverse to the respective end plate and generally transverse to the same edge of the respective end plate leaving an open space between said walls at said edge of a said plate for access to the space therebetween; means mounting said first and second coil forms with the end plates thereof opposing each other and spaced apart to align said walls of the respective terminal board means of said end plates of said first and second coil forms to form with said end plates at least one semi-enclosed compartment for housing an electrical connection in a protected relationship which is fully accessible from the exterior in the space between the said walls of each said end plate, and an opening formed in at least one of the end plates forming the semi-enclosed compartment to permit passage of a wire through said opening into the compartment, and a terminal support base projecting outwardly from at least one of said end plates generally transverse thereto and into a said semi-enclosed compartment.
Claim 6
Dependent Claim
234 words
Electrical apparatus comprising first and second coil forms each having a center leg on which a coil of wire is wound and an end plate on an end of each such leg; a respective terminal board means extending outwardly from said end plate of each coil form, each said terminal board means including at least a pair of elongated walls spaced apart and extending generally transverse to the respective end plate and generally transverse to the same edge of the respective end plate leaving an open space between said walls at said edge of a said plate for access to the space therebetween; means mounting said first and second coil forms with the end plates thereof opposing each other and spaced apart to align said walls of the respective terminal board means of said end plates of said first and second coil forms to form with said end plates at least one semi-enclosed compartment for housing an electrical connection in a protected relationship which is fully accessible from the exterior in the space between the said walls of each said end plate, and an opening formed in at least one of the end plates forming the semi-enclosed compartment to permit passage of a wire through said opening into the compartment, and a terminal support base projecting outwardly from at least one of said end plates generally transverse thereto and into a said semi-enclosed compartment.
Claim 7
Dependent Claim
13 words
Apparatus as in claim 4, wherein said support base includes an upstanding lug.
Claim 8
Dependent Claim
14 words
Apparatus as in claim 5, wherein said lug includes an upwardly rising rear portion.
Claim 9
Dependent Claim
21 words
Apparatus as in claim 5, wherein said terminal base support includes at least one hole on each side of said lug.
Claim 10
Dependent Claim
36 words
Apparatus as in claim 7, wherein one hole on one side of said lug is located further from the end plate of the corresponding terminal board than the hole on the other side of the lug.
Claim 11
Dependent Claim
58 words
Apparatus as in claim 4, further comprising a terminal connector mounted on a said terminal support base, said terminal connection of electrically conductive wire having a hollow central body portion adapted for a solder connection of another wire and an arm extending from at least one end of said coil adapted for a mechanical connection of another wire.
Claim 12
Dependent Claim
31 words
Apparatus as in claim 9, wherein an arm extends from each end of said coil, said arms being generally transverse to the central longitudinal axis of said hollow central body portion.
Claim 13
Dependent Claim
55 words
Apparatus as in claim 4, wherein two aligned walls on each of the terminal boards of said first and second coil foRms each have a portion of an opening therein which forms an opening when the two walls are aligned to permit passage of a wire through said opening into a portion of the compartment.
Claim 14
Dependent Claim
43 words
Electrical apparatus as in claim 4 further comprising a bottom wall on each said end plate extending transversely thereto and joining the pair of walls of each said terminal board at the end thereof remote from said edge of the said end plates.
