Abstract
Abstract A connector for making an electrical connection with the metal shield of an electrical cable having a plurality of insulated conductors, an inner metal shield over the conductors, and an outer insulated sheath over the shield. A unitary connector of resilient metal with a central section and opposed outer sections for sliding onto the end of a cable, with the central section between the conductors and shield and with the outer sections overlying the sheath. A plurality of teeth on a tongue of the central section for engaging the shield, and lanced or sheared tips on the outer sections for engaging the sheath.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A screwless connector for making an electrical connection with the metal shield of an electrical cable having a plurality of insulated conductors, an inner metal shield over the conductors, and an outer insulating sheath over the shield, said connector comprising a single unitary metal piece having a central section and opposed outer sections joined to said central section, with said outer sections generally parallel to and spaced upward from said central section and spaced outward on opposite sides of said central section, said central section having a tongue carrying a plurality of teeth, with said teeth directed upward toward said outer sections, with said outer sections having tips directed downward toward said central section, with said tongue adapted for sliding into the cable between the conductors and shield with said teeth engaging the shield and with said outer sections overlying the sheath with said tips engaging the sheath.
Claim 2
Dependent Claim
148 words
A screwless connector for making an electrical connection with the metal shield of an electrical cable having a plurality of insulated conductors, an inner metal shield over the conductors, and an outer insulating sheath over the shield, said connector comprising a single unitary metal piece having a central section and opposed outer sections joined to said central section, with said outer sections generally parallel to and spaced upward from said central section and spaced outward on opposite sides of said central section, said central section having a tongue carrying a plurality of teeth, with said teeth directed upward toward said outer sections, with said outer sections having tips directed downward toward said central section, with said tongue adapted for sliding into the cable between the conductors and shield with said teeth engaging the shield and with said outer sections overlying the sheath with said tips engaging the sheath.
Claim 3
Dependent Claim
162 words
A connector formed of a resilient material for making an electrical connection with the metal shield of an electrical cable having a plurality of insulated conductors, an inner metal shield over the conductors, and an outer insulating sheath over the shield, said connector comprising a unitary metal piece having a central section and opposed outer sections joined to said central section, with said outer sections generally parallel to and spaced upward from said central section, said central section having a tongue carrying a plurality of teeth, with said teeth directed upward toward said outer sections, with said tongue adapted for sliding into the cable between the conductors and shield with said teeth engaging the shield and with said outer sections overlying the sheath, and with said outer sections spaced from said central section a distance less than the thickness of the sheath and shield to provide a compression force on the sheath and shield when said connector is positioned on the cable.
Claim 4
Dependent Claim
162 words
A connector formed of a resilient material for making an electrical connection with the metal shield of an electrical cable having a plurality of insulated conductors, an inner metal shield over the conductors, and an outer insulating sheath over the shield, said connector comprising a unitary metal piece having a central section and opposed outer sections joined to said central section, with said outer sections generally parallel to and spaced upward from said central section, said central section having a tongue carrying a plurality of teeth, with said teeth directed upward toward said outer sections, with said tongue adapted for sliding into the cable between the conductors and shield with said teeth engaging the shield and with said outer sections overlying the sheath, and with said outer sections spaced from said central section a distance less than the thickness of the sheath and shield to provide a compression force on the sheath and shield when said connector is positioned on the cable.
Claim 5
Dependent Claim
43 words
A connector as defined in claim 2 wherein each of said outer sections has inner and outer edges, with a downwardly projecting tip on each of said inner edges and with said tips directed toward the junction of said central and outer sections.
Claim 6
Dependent Claim
23 words
A connector as defined in claim 3 wherein the height of successive teeth of said tongue increases in the direction of said junction.
Claim 7
Dependent Claim
17 words
A connector as defined in claim 4 wherein said tongue has two spaced rows of said teeth.
Claim 8
Dependent Claim
21 words
A connector as defined in claim 4 wherein said teeth have a rake with the tips thereof inclined toward said junction.
Claim 9
Dependent Claim
29 words
A connector as defined in claim 1 wherein the height of successive teeth of said tongue increases in the direction of the junction of said central and outer sections.
Claim 10
Dependent Claim
17 words
A connector as defined in claim 7 wherein said tongue has two spaced rows of said teeth.
Claim 11
Dependent Claim
21 words
A connector as defined in claim 7 wherein said teeth have a rake with the tips thereof inclined toward said junction.
