Abstract
Abstract Making a branch connection with a flat cable and affording shielding is afforded by removing insulation at three longitudinally spaced locations transversely of the cable, folding the cable at the intermediate location, making connection to the signal leads at the intermediate location, cutting ground leads, folding ground leads at other two locations, and joining a portion of a conductive member to the ground leads on each side of the cable and by straps at the fold joining the portions of the conductive member affording ground contacts.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
188 words
A method of forming branch connection of a flat cable, having earth leads and signal leads comprising the steps of: removing an insulation coating of a flat cable in a transverse direction relative to the flat cable at three longitudinal portions thereof, thereby exposing all of the leads of the flat cable at said three portions; folding the flat cable at the intermediate exposed lead portion of said three portions; cutting the earth leads of the flat cable at the intermediate exposed lead portions; causing each of the earth leads of the flat cable at the exposed portions to project toward and beyond an outside surface of the folded cable; causing the signal leads of the leads of the flat exposed lead portions to project toward the folded ends thereof keeping the folded condition thereof; electrically connecting the earth leads on both surfaces of overlapped portions to a common earth lead connecting means at said both surfaces; and electrically connecting each of the folded projecting portions of the signal leads and of the common earth lead connecting means to a corresponding connection terminal of branch signal output means.
