10-pin ribbon cable mount connector with strain relief
The two ribbon cables, one with 10 conductors and one with 34 conductors, may require
assembly or may have the connectors already installed. If the connectors are not already
installed, assemble the two cables with a connector at each end. Align the red conductor with
pin 1 on both connectors
See illustrations below:
(left) 10C cable shown with red conductor at top
(right) Connector top and front view shows position of pin 1 on 10-pin connector. The first and
last pins are marked on the front of the connector but the numbers cannot be seen without a
magnifying glass. The 34-pin connector has the same configuration
Insert the cable between the cable clamp and the connector body with the red conductor on the
side where pin 1 is located. Squeeze the clamp and body together in a small vise. If necessary,
cover the vise faces with hard wood to keep from marring the connectors. Be careful to align the
cable at right angles to the clamp and body. After assembly, trim the cable with a razor blade or
hobby knife
After the connectors are installed, fold the cable over the top of the connector and snap the
strain relief into place
