Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A fusible terminal means having a body portion provided with cable insulation crimping means for connecting the body portion to a cable insulation, a head portion provided with terminal connecting means for connecting the head portion to a mating terminal connecting means, a throat portion connecting the head and body portion together and having cable wire crimping means for connecting the throat portion to a bare cable wire, the throat portion further having a fuse bridge means of reduced cross-sectional area, and a rigid insulator bridge support means connected to the throat portion across the fuse bridge means for rigidifying the fuse bridge means and for preventing the separation of the head portion from the body portion in the event of fusing of the fuse bridge means, the rigid insulator bridge support means comprising a cylindrical insulator connected across the reduced cross-sectional area by axial spaced apart insulator grip means on the throat portion.
Claim 2
Dependent Claim
154 words
A fusible terminal means having a body portion provided with cable insulation crimping means for connecting the body portion to a cable insulation, a head portion provided with terminal connecting means for connecting the head portion to a mating terminal connecting means, a throat portion connecting the head and body portion together and having cable wire crimping means for connecting the throat portion to a bare cable wire, the throat portion further having a fuse bridge means of reduced cross-sectional area, and a rigid insulator bridge support means connected to the throat portion across the fuse bridge means for rigidifying the fuse bridge means and for preventing the separation of the head portion from the body portion in the event of fusing of the fuse bridge means, the rigid insulator bridge support means comprising a cylindrical insulator connected across the reduced cross-sectional area by axial spaced apart insulator grip means on the throat portion.
Claim 3
Dependent Claim
38 words
A fusible terminal means according to claim 1 wherein the insulator grip means comprise two pairs of axially spaced apart crimping fingers on opposite sides of the reduced cross-sectional area adapted to be crimped around the cylindrical insulator.
Claim 4
Dependent Claim
42 words
A fusible terminal means according to claim 2 wherein a band of color coated insulating material is connected to the cable adjacent the body portion of the fusible terminal means for insulating the body portion and identifying the terminal means as fusible.
Claim 5
Dependent Claim
49 words
A fusible terminal means according to claim 3 wherein the cable crimping means comprise a pair of gripping fingers adapted to be crimped to the cable insulation, and the cable wire crimping means comprise a pair of wire gripping fingers adapted to be crimped to the bare cable wire.
