Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
An electrical stab connector, comprising: (a) a plurality of electrical contact fingers disposed to make contact with an electrical bus means for supplying electrical power thereto; (b) an eddy-current bus means for carrying eddy-currents disposed in a position generally parallel with said plurality of electrical contact fingers; (c) an air gap isolating said eddy-current bus means from said plurality of electrical contact fingers; and (d) said eddy-current bus means is comprised of an electrical conducting material whereby eddy-currents are induced into said eddy-current bus means to create electromagnet forces that repel said plurality of electrical contact fingers into engagement with said electrical bus means.
Claim 2
Dependent Claim
104 words
An electrical stab connector, comprising: (a) a plurality of electrical contact fingers disposed to make contact with an electrical bus means for supplying electrical power thereto; (b) an eddy-current bus means for carrying eddy-currents disposed in a position generally parallel with said plurality of electrical contact fingers; (c) an air gap isolating said eddy-current bus means from said plurality of electrical contact fingers; and (d) said eddy-current bus means is comprised of an electrical conducting material whereby eddy-currents are induced into said eddy-current bus means to create electromagnet forces that repel said plurality of electrical contact fingers into engagement with said electrical bus means.
Claim 3
Dependent Claim
19 words
An electrical stab connector as recited in claim 1 wherein said eddy current bus means is comprised of aluminum.
Claim 4
Dependent Claim
19 words
An electrical stab connector as recited in claim 1 wherein said eddy current bus means is comprised of copper.
Claim 5
Dependent Claim
113 words
An electrical stab connector, comprising: (a) a plurality of electrical contact fingers disposed to make contact with an electrical bus means for supplying electrical power thereto; (b) an eddy-current bus means for carrying eddy-currents induced from said electrical bus means; (c) an air gap isolating said eddy-current bus means from said plurality of electrical control fingers; and (d) said eddy current bus means is generally comprised of a slot motor means having a laminated magnetic yoke disposed generally around said plurality of electrical contact fingers whereby magnetic flux generated across an air gap results in magnetic attraction for pulling said contact fingers into a slot to maintain contact pressure with the bus means.
Claim 6
Dependent Claim
113 words
