Type C Cable Clamping
This system has an earthing sleeve
and a collet
which is compressed by the collet nut
to ensure a good clamp
onto the cable. When assembling the connector, the cable shield is gripped between the earthing sleeve and the collet.
Cable Fixing
Cable fixing onto LEMO connectors is determined by the
connector model. This is achieved either with a cable
collet system or with hexagonal crimping (MIL-C-22520F,
type 2).
The collet system cable fixing is made without any spe-
cial tooling. The crimping method guarantees a good
electrical continuity of the shield which improves greatly
the shielding efficiency of the cable/connector link.
