Plastic cavities, designed
to Tyco Electronics
specifications, may be
molded as part of the coil
bobbin or attached to a
lamination stack in the area
of the magnet wire coil.
Each cavity is a rectangular
box with two narrow slots on
opposing walls and a
plastic cutoff or tie-off post.
During or after the winding
process, the magnet wire is
placed across the plastic
cavities and into the slots,
either manually or by coil
winding equipment.
Unraveling is prevented by
a slight friction fit, suitable
bend or by wrapping the
magnet wire around the tie-
off post.
During insertion, the
insulation displacing
terminal slot strip the film
insulation from the magnet
wire producing a stable
electrical termination.
Terminal retention is
retained in the plastic
cavities by single or multiple
locking barbs or locking
latches for large quick
disconnect FASTON tab
terminals.
Excess magnet wire is
trimmed flush with the
outside of the plastic cavity
by a shear blade traveling
with the terminal insertion
ram.
Tyco Electronics can
provide design and mold
engineering resources to
manufacture most
specifically designed
SIAMEZE cavity housings.
