Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A shielded multiple-conductor cable comprising: a plurality of insulated wires forming a conductor bundle and wound in a contra-helical direction; a first layer of insulative material wrapped around the conductive bundle; a first tie wrap, wound in a spaced spiral around the conductor bundle and overlying the insulative layer; a plurality of closely spaced, uninsulated, untwisted, parallel wires extending along the longitudinal axis of the cable overlying the first tie wrap; a second tie wrap, wound in a spaced spiral around the wires and positioned alternately of the first tie wrap; and a second layer of abrasion resistant insulative material providing a covering for the shield and conductor bundle.
Claim 2
Dependent Claim
109 words
A shielded multiple-conductor cable comprising: a plurality of insulated wires forming a conductor bundle and wound in a contra-helical direction; a first layer of insulative material wrapped around the conductive bundle; a first tie wrap, wound in a spaced spiral around the conductor bundle and overlying the insulative layer; a plurality of closely spaced, uninsulated, untwisted, parallel wires extending along the longitudinal axis of the cable overlying the first tie wrap; a second tie wrap, wound in a spaced spiral around the wires and positioned alternately of the first tie wrap; and a second layer of abrasion resistant insulative material providing a covering for the shield and conductor bundle.
Claim 3
Dependent Claim
86 words
A shielded multiple-conductor cable comprising: a plurality of insulated wires forming a conductor bundle and wound in a contra-helical direction; a first layer of insulative material wrapped around the conductive bundle; a first tie wrap wound in a spaced spiral around the conductor bundle and overlying the insulative layer; and a plurality of closely spaced, uninsulated wires extending along the longitudinal axis of the cable overlying the first tie wrap, wound in a spaced spiral around the wires and positioned alternately of the first tie wrap.
Claim 4
Dependent Claim
86 words
A shielded multiple-conductor cable comprising: a plurality of insulated wires forming a conductor bundle and wound in a contra-helical direction; a first layer of insulative material wrapped around the conductive bundle; a first tie wrap wound in a spaced spiral around the conductor bundle and overlying the insulative layer; and a plurality of closely spaced, uninsulated wires extending along the longitudinal axis of the cable overlying the first tie wrap, wound in a spaced spiral around the wires and positioned alternately of the first tie wrap.
