Endoscope having crimped and soldered cable terminator
First Claim
1. An endoscope having an insertion tube with a bending section at its distal end, said insertion tube further includinga viewing head contained at the distal end of the insertion tube in front of the bending section,a stop plate positioned between the viewing head and the bending section,at least one control cable having a distal end that passes through both the bending section and the stop plate, andterminating means mounted on the distal end of the cable adjacent the stop plate, the terminating means including a helically wound spring that is mounted entirely upon the distal end of the cable and is crimped inwardly along its entire axial length to form a first mechanical joint against the cable and open spaces between adjacent turns of the spring, and a flowable bonding material filling the spaces between the cable and the spring to form a fused bond second joint between the spring and the cable.

Abstract
An Endoscope having at least one control cable wherein a helically wound cylindrical spring is passed over one end of the cable and is crimped into deforming contact against the cable. Melted solder is flowed over and through the spring to wet the spring and the cable surfaces. The solder is allowed to solidify thus creating a strong joint between the cable and the spring.
