Abstract: A combination of a connector (12) and an armored cable (14), where several inches of the front end of the cable armor tube (20) are stripped away to allow a front portion of the cable to bend up to about 90°. A flexible polymer overmold (50) is molded around the front of the armor tube and the rear of the connector and the several inches of wire extending forward of the armor tube. The wire front portions (54) are twisted at least a full turn about the cable axis (44) prior to the overmolding, to reduce wire tension when the front portion of the cable is bent. The overmold has flanges (102) that bottom on one another at a 90° bend of a moderate radius of curvature (R). A wire mesh braiding (80) has a rear end clamped (92) and soldered to the armor and a front end clamped (96) to the connector. An air valve (130) is automatically opened when connectors mate.
