Harness Design Checklist
Protection
Once the connectors and
wires have been specified,
the method of protection
must be considered.
Various jacket materials are
available to protect the
wires and these can be
extruded or heat-shrink.
Jacket material formulations
are compounded to meet a
wide range of environmental
demands.
Similarly, protection for the
wire termination must be
considered. In general, the
wires will be terminated to
connector contacts.
Protection products must
protect the joints from dam-
age caused by mechanical
stress such as flex, torque
and tensile load, and corro-
sion or electrical breakdown
from fluid ingress, while
retaining the ability to be
repaired. All these influ-

ences and more must be
considered when choosing
the termination protection
method.
Shielding and Shield
Termination
Step 3 of the component
selection process dis-
cussed later in this section
gives advice on choosing
the appropriate shielding
products for the gross
shield. Consideration must
also be given to the individ-
ual cable shield termina-
tions. Can they be pigtailed
together with a common
termination to a contact or
to earth, or should they have
individual terminations?
If using a solder device, the
correct choice is based,
not only on size, but also
temperature rating or
compatibility with the cable
braid.
Pins or sockets?
Temperature extremes?
Temperature cycling?
Voltage?
Current?
Signal transmission (impedance, velocity, frequency, etc.)?
Is circuit integrity critical? What if the circuit fails?
Sealed or unsealed?
Made of plastic or metal?
Crimp or solder contacts?

Identification
Circuit identification is
important, both in manufac-
ture, where an assembly
operator must ensure
correct wire to contact
termination, and in repair,
where a damaged
connector may need
replacing in difficult
circumstances and contact
positions have to be easily
identified. Individual wire
markers help with these
two circumstances. Where
a cable is severed and
access to the ends is
prevented, unique identifi-
cation on the wires, or wire
color coding aids repair.
Consideration given to the
identification of harness
legs is also important.
Connectors will normally be
chosen with unique keying
to prevent incorrect mating
but end identification will

speed up plugging,
particularly for multi-

It is also good practice to
label the harness with its
part numbers and other
relevant information for
traceability purposes.
