Contact resistance with relation to the number
of mating cyles
(measured according to IEC 60512-2 test 2a)
Maximum values measured after the mating cycles and
the salt spray test according to IEC 60512-6 test 11f.
Solder contacts
The conductor bucket of these contacts is machined at an
angle to form a cup into which the solder can flow.
See page 9 for the range of cable dimensions that can be
soldered.
Crimp contacts
The square form crimp method is used (MIL-C-22520F,
class I, type 2) photo 1 for unipole contacts.
For multipole contacts the standard four identer crimp
method is used, MIL-C-22520F, class I, type 1), photo 2.
The crimp method requires a controlled compression to
obtain a symmetrical deformation of the conductor strand and
of the contact material. The radial hole in the side of the contact
makes it possible to check whether the conductor is correctly
positioned within the contact. A good crimping is characte-
rized by only slightly reduced conductor section and prac-
tically no gap.
For optimum crimping of bronze or brass contacts they are
annealed to relieve internal stress and reduce material har-
dening during the crimping process.
Only the crimping zone is annealed with the help of an
induction heating machine designed by the LEMO Research
and Development Department (see photo 3).
Crimp contacts
The crimp contacts can be with two forms: a standard crimp
barrel for large conductors (see fig. 1) or with a reduced
crimp barrel for smaller conductors (see fig. 2).

Insulation resistance between the contacts and
contact/shell
(measured according to IEC 60512-2 test 3a)
Note:
1)
Advantages of crimping
– practical, quick contact fixing outside the insulator
– possible use at high temperature
– no risk of heating the insulator during the conductor-
– high tensile strength
Crimp contacts are available in standard version (form 1) for
mounting maximum size conductors.
For some dimensions, these crimp contacts can be produ-
ced with reduced crimp barrels (form 2) for mounting redu-
ced size conductors.
The range of cable dimensions that can be crimped into
our contacts are indicated on the table on page 9.
