Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A spade terminal having one end and an opposite end, said one end having a pair of parallel slits extending longitudinally along the center of said terminal forming a spring strip and a pair of margins on opposing sides of said strip, said strip being bulged outwardly from the plane of said terminal and said margins being bulged outwardly from the plane of said terminal in a direction opposite from that of said strip thereby forming a loop and whereas said bulging of said margins are suitable to engage with a female spade connector.
Claim 2
Dependent Claim
94 words
A spade terminal having one end and an opposite end, said one end having a pair of parallel slits extending longitudinally along the center of said terminal forming a spring strip and a pair of margins on opposing sides of said strip, said strip being bulged outwardly from the plane of said terminal and said margins being bulged outwardly from the plane of said terminal in a direction opposite from that of said strip thereby forming a loop and whereas said bulging of said margins are suitable to engage with a female spade connector.
Claim 3
Dependent Claim
20 words
A spade terminal as defined in claim 1, in which said opposite end is U-shaped to receive a mating terminal.
Claim 4
Dependent Claim
32 words
A spade terminal as defined in claim 2, in which said U-shaped end is curled outwardly and cantilevered from the main body off the axis of the main body of said terminal.
Claim 5
Dependent Claim
43 words
A spade terminal as defined in claim 3, in which legs of said U-shaped end are spring loaded; whereby said U-shaped end applies pressure to mating terminal from three sides and passage of current is distributed over the full area of said U-shape.
Claim 6
Dependent Claim
38 words
A spade terminal as defined in claim 1 whereas the said bulged portions are spring loaded and therefore elastically deform when fit into a conventional female spade connector, thereby generating a pressure between said terminal and said connector.
Claim 7
Dependent Claim
95 words
A spade terminal for connecting electrical leads formed with a U-shape on one end in combination with a mating terminal embraced by the legs of said U, whereas the opening of said U, which removably receives said mating terminal, is curled outwardly and cantilevered from main body of said terminal; and whereas said curled U is off axial position with main body of said terminal; and whereas said U is spring loaded, wherefore current passes into said mating terminal through both legs of said U shape and said U clamps with pressure said mating terminal.
Claim 8
Dependent Claim
95 words
A spade terminal for connecting electrical leads formed with a U-shape on one end in combination with a mating terminal embraced by the legs of said U, whereas the opening of said U, which removably receives said mating terminal, is curled outwardly and cantilevered from main body of said terminal; and whereas said curled U is off axial position with main body of said terminal; and whereas said U is spring loaded, wherefore current passes into said mating terminal through both legs of said U shape and said U clamps with pressure said mating terminal.
