Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
182 words
An electromagnetic relay comprising relay contacts, a magnetic coil adapted to be selectively energized to operate said contacts, said coil comprising an elongated wound conductor having spaced ends, an insulating base, a supporting frame for supporting said coil on said base, said frame having a pair of spaced bores, a pair of pin terminals inserted into said bores respectively, said spaced ends of said coil conductor being connected to said pair of pin terminals respectively at positions within said bores, each of said pin terminals having a portion extending outwardly from its associated bore and projecting outwardly of said frame, a pair of spaced connecting terminals extending through said insulating base, each of said pair of connecting terminals including an interior section extending from one side of said insulating base toward said frame and defining a notch located adjacent one of said outwardly projecting pin terminal portions respectively, said projecting pin terminal portions being seated in said notches in mechanical engagement with the interior sections of said terminals to effect electrical connection between said spaced connecting terminals and said spaced coil ends.
Claim 2
Dependent Claim
182 words
An electromagnetic relay comprising relay contacts, a magnetic coil adapted to be selectively energized to operate said contacts, said coil comprising an elongated wound conductor having spaced ends, an insulating base, a supporting frame for supporting said coil on said base, said frame having a pair of spaced bores, a pair of pin terminals inserted into said bores respectively, said spaced ends of said coil conductor being connected to said pair of pin terminals respectively at positions within said bores, each of said pin terminals having a portion extending outwardly from its associated bore and projecting outwardly of said frame, a pair of spaced connecting terminals extending through said insulating base, each of said pair of connecting terminals including an interior section extending from one side of said insulating base toward said frame and defining a notch located adjacent one of said outwardly projecting pin terminal portions respectively, said projecting pin terminal portions being seated in said notches in mechanical engagement with the interior sections of said terminals to effect electrical connection between said spaced connecting terminals and said spaced coil ends.
Claim 3
Dependent Claim
35 words
The relay of claim 21 wherein each of said interior sections comprises a bifurcated element the bifurcations of which extend transversely to said pin terminals, said notch being defined between the bifurcations of said element.
Claim 4
Dependent Claim
67 words
The relay of claim 2 wherein each of said bores comprises an elongated cylindrical recess opening into an end of said frame and adapted to receive one of said pin terminals, and a slot extending laterally from said cylindrical recess through a side of said frame for permitting passage of one of said coil ends through said frame to the pin terminal portion within said cylindrical recess.
