Abstract
Abstract Before crimping, a flat wire connector has a cross-section which is somewhat U-shaped with upstanding side plates having serrations on the top and a rosette of upstanding tines in the floor. When the connector is crimped, the flat wire is pressed down over the rosette, the tines of which pierce the insulation. The two upstanding side walls are rolled in toward the middle of the U, and the serrations are driven downwardly to pierce the insulation and stake the flat wire. The length of the side walls is such that the flat wire may be badly out of alignment with respect to the connector and yet insure a good electrical connection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A flat wire connector comprising a terminal member and an integral ferrule member, said ferrule being U-shaped in crosssection having upstanding side walls connected by a floor section, the top edges of said side walls being serrated along at least a partial length, said serrations extending longitudinally from a position adjacent said terminal, said ferrule including a non-serrated gripping portion extending from a position adjacent the opposite end of said ferrule and along the top edges of said side walls, said gripping portion terminating in an outwardly extending edge portion having an outwardly decreasing crosssectional thickness for relieving mechanical fatigue at the point where said flat wire enters said connector.
Claim 2
Dependent Claim
110 words
A flat wire connector comprising a terminal member and an integral ferrule member, said ferrule being U-shaped in crosssection having upstanding side walls connected by a floor section, the top edges of said side walls being serrated along at least a partial length, said serrations extending longitudinally from a position adjacent said terminal, said ferrule including a non-serrated gripping portion extending from a position adjacent the opposite end of said ferrule and along the top edges of said side walls, said gripping portion terminating in an outwardly extending edge portion having an outwardly decreasing crosssectional thickness for relieving mechanical fatigue at the point where said flat wire enters said connector.
Claim 3
Dependent Claim
33 words
The flat wire connector of claim 1 and means for physically separating Said serrated edges and said gripping portion to provide separate ferrule parts having independent mechanical gripping and electrical contact making functions.
Claim 4
Dependent Claim
41 words
The connector of claim 1 and a rosette of upstanding sharp pointed tines in the floor of said U-shaped section, said rosette of tines being positioned to pierce a flat wire positioned in said U-shaped section when said ferrule is crimped.
Claim 5
Dependent Claim
40 words
The connector of claim 1 and means for rolling the side wall portion with serrated edges to curl over toward the center of the U-shaped section and pierce the insulation of a flat wire in the bottom of said U-shape.
Claim 6
Dependent Claim
57 words
The connector of claim 4 and at least one upstanding tine in the floor of said U-shaped section, said upstanding tine being positioned under the serrations of said side walls when in said rolled position whereby the driving of said serrations into said insulation during a crimping operation tends to crimp the top of the upstanding tine.
Claim 7
Dependent Claim
88 words
A flat wire connector comprising a ferrule portion having somewhat U-shaped cross-section with serrations extending longitudinally along a first section on the tops of the side walls of the U-shaped cross-section and at least one upstanding sharp pointed tine in the bottom of the U-shaped cross-section, said side walls rolling over during crimping to drive said serrations and said tine through said flat wire, and having chamfered means at the end of said ferrule for relieving mechanical fatigue at the point where said flat wire enters said connector.
Claim 8
Dependent Claim
88 words
A flat wire connector comprising a ferrule portion having somewhat U-shaped cross-section with serrations extending longitudinally along a first section on the tops of the side walls of the U-shaped cross-section and at least one upstanding sharp pointed tine in the bottom of the U-shaped cross-section, said side walls rolling over during crimping to drive said serrations and said tine through said flat wire, and having chamfered means at the end of said ferrule for relieving mechanical fatigue at the point where said flat wire enters said connector.
Claim 9
Dependent Claim
29 words
The connector of claim 6 and means comprising the tine at the bottom of the U-shape for riveting or stapling the flat wire to the bottom of the connector.
Claim 10
Dependent Claim
23 words
The connector of claim 7 and gripping ears formed in said walls for holding said flat wire in mechanical connection with said connector.
