Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
92 words
An electrical terminal for aluminum wire, comprising a barrel portion and a contact portion, tines directed inwardly of the barrel portion adjacent one end adapted mechanically to grip an insulated wire having an aluminum core receivable in the barrel, at least two inwardly extending cutting edges spaced apart longitudinally and extending transversely of the barrel portion between the tines and the contact portion adapted to penetrate the insulation electrically to contact the aluminum core on crimping the terminal and the wire, the cutting edges being inclined apart longitudinally of the barrel portion.
Claim 2
Dependent Claim
92 words
An electrical terminal for aluminum wire, comprising a barrel portion and a contact portion, tines directed inwardly of the barrel portion adjacent one end adapted mechanically to grip an insulated wire having an aluminum core receivable in the barrel, at least two inwardly extending cutting edges spaced apart longitudinally and extending transversely of the barrel portion between the tines and the contact portion adapted to penetrate the insulation electrically to contact the aluminum core on crimping the terminal and the wire, the cutting edges being inclined apart longitudinally of the barrel portion.
Claim 3
Dependent Claim
91 words
An electrical terminal for installed aluminum wire, including a wire-receiving portion, tines directed inwardly of the wire-receiving portion adjacent one end thereof, the tines being adapted mechanically to grip an insulated wire having an aluminum core receivable in the wire-receiving portion, at least two inwardly extending cutting edges spaced apart longitudinally and extending transversely of the wire-receiving portion to penetrate the insulation electrically to contact the aluminum core on crimping, the cutting edges being formed from the floor of the wire-receiving portion and being inclined apart longitudinally of the wire-receiving portion.
Claim 4
Dependent Claim
91 words
An electrical terminal for installed aluminum wire, including a wire-receiving portion, tines directed inwardly of the wire-receiving portion adjacent one end thereof, the tines being adapted mechanically to grip an insulated wire having an aluminum core receivable in the wire-receiving portion, at least two inwardly extending cutting edges spaced apart longitudinally and extending transversely of the wire-receiving portion to penetrate the insulation electrically to contact the aluminum core on crimping, the cutting edges being formed from the floor of the wire-receiving portion and being inclined apart longitudinally of the wire-receiving portion.
