Harwin C90 User Manual

INSTALLATION PROCEDURE FOR SPRING ADAPTOR

This instruction sheet is to aid in the assembly of the following MIL-DTL-5015 connectors to
braided cable:

 C90-002-10SL
 C90-002-12S
 C90-002-14S

a) Prepare the cable making sure that a sufficient length of shield is available, so that it fits

against the front shoulder of the lip groove.

b) Before insertion of connector contacts, slide the heat-shrinkable connector boot onto the

cable, followed by the Spring Adaptor.

c) Position the heat shrinkable boot, Spring Adaptor, and braid out of the way, and insert the

connector contacts. Depending upon the shielding braid size it can either be folded back
onto itself or bunched up concertina style out of the way for easy access to the cable
conductors.

d) Slide the Spring Adaptor forward, over the braid, and pull the braid back so it is not

trapped under the Adaptor.

e) Screw the Spring Adaptor onto the connector and tighten to the torque value specified in

the table below. It is recommended that the connector threads are lubricated with a
suitable compound if a liquid thread lock is not used. The Adaptor should be hand
tightened to ensure proper thread alignment and then tightened with a strap wrench and
torque meter to the specified torque.

10SL 40 4.5

12S 40 4.5
14S 40 4.5

f) Bring the cable shield braid up onto the adaptor body so that it fits against the front

shoulder of the lip groove. Alternatively extend the braid past the lip groove.
Note: After assembly, braid can be trimmed with side cutters or folded back and secured
with high temperature tape.

g) Open up the constant force spring and wrap it around the cable braid section that is

positioned over the constant force spring slot area of the adaptor. This is most easily
accomplished by lifting up the end of the spring and trapping the braid covered adaptor
between the spring coil and raised end. The spring will now stay in place and can be
installed by simply rolling the spring coil around the braid covered adaptor.

h) Install heat shrink connector boot over braid and back of Adaptor, use industry standard

best practices.
