Use of CHAMP connector
systems involves other
important decisions; choice
of locking hardware, and
choice of strain relief system/covers.
Since the
finished connection
includes two connector
halves (plug/male and
receptacle/female), careful
planning is essential to
mechanically protect contact
terminations and to
maintain electrical integrity
of mated connectors.
Locking Hardware Options
Locking hardware is used
to secure mating CHAMP
connectors and to prevent
unintentional separation.
The following choices grew
from widely-varied application
needs—for reasons of
economics, convenience,
sophistication, or standardization,
for example. Refer
to Instruction Sheet
IS 3160.
Locking Latch (CHAMP-LOK
Connector Design)
Standard CHAMP connectors
(except those for IEEE
and shielded applications)
are provided with guide
tracks and slots (on plugs)
and lead-in ramps (on
receptacles) to allow use of
a simple metal locking clip
for securing mated connectors.
The U-shaped locking
latch is designed in three
sizes—with the same basic
part number, but with different
dash numbers: No.
552723-1 is used for 36-
and 50-position connectors,
552723-2 for 14- and
24-position connectors,
and 552723-3 for 64-position
connectors.
No tools are required for
this locking system. Simply
slide the latch onto guide
tracks until tabs snap into
slots. As connector halves
are mated, tabs engage
with lead-in ramps and
spring over locking shoulder
into receptacle slots.
Locking is assured by an
audible click. To release,
push the latch forward to
free tabs from slots. Note
that locking latches cannot
be used in rear-panelmount
applications
because of panel interference,
nor can they be used
with CHAMP shielded
and competitive connectors.
However, when
CHAMP-LOK latches are
used in conjunction with
snap-in strain relief covers
(panel-mount applications
only), no other hardware is
necessary.
Screw Lock Hardware
Screw lock hardware is
generally used in sensitive
or sophisticated applications
where positive locking
is required—to secure connectors
to PC boards, to
panels, and/or to each
other. In cable-to-cable
applications, two captive
screws threaded into pretapped
holes are generally
the only screw lock requirements.
In mounted
applications, receptacle
assemblies are usually fastened
to boards or
panels—with standoff
screws, nuts, and bolts.
The head of this special
standoff screw has a
threaded hole that accepts
a captive screw, used to
secure the mating connector.
Screw lock hardware
kits vary with connector
types and applications—
panel or board thickness,
front- or rear-panel mount,
for example.
Bail Lock Hardware
(Standard or Bent)
Bail Lock hardware provides
both locking and
quick-release capabilities
at both ends of mated connectors.
Flanges on
CHAMP plug connectors
must be open ended for all
bail lock applications. The
open-end flanges accept
bail clips (straight or bent
90°) mounted to a mating
receptacle connector.
Standard bail clips are
used where access to lock
and release is not a problem.
Bent bail locks are
used primarily with right
angle (90°) cable terminations
where space is
limited. Typical hardware
kits include bail clips, flat
and lock washers, mounting
screws and nuts.
CHAMP Connectors with
Integral Latches
These special CHAMP connectors
are designed with
an integral latching system
that eliminates the need for
additional locking hardware.
Receptacle
assemblies are preassembled
with two plated steel
spring catches (one at
each end) that latch into
cutout slots in mating plug
connectors. To release a
mated pair, simply depress
catches into recessed
areas and disengage.
Note, however, that integral
latches are not repairable
or replaceable. Integrallatch
connectors are
presently available in 24-,
36-, 50- and 64-position
sizes.
J-Hook Hardware
The J-hook is a precisionformed
metal bracket used
as an alternate quick-fastening
method for
assembly hardware. Two
tabs fit into recesses in the
connector housing flange
for screw-fastening. The
inverted end of the J-hook
snaps on the end of a mating
connector, and holds it
in place. This hardware is
also used in confined areas
instead of bent bail lock—
with 90° two-piece, low- or
standard-profile strain relief
covers.
