Subconn OM Handling Procedure
Introduction
The Subconn OM series of connectors is
supplied as a quick, reliable and watertight solution
for customers who require installation of standard Subconn
connectors on a non-standard cable or for quick, efficient
field retermination. The OM connector series mates with
the compatible standard Subconn series. The connectors
are produced with a tube brass body and 7 cm pigtail
wires which are spliced and moulded to the cable using
a pre-formed "Boot" and pre-packed ambient temperature
curing polyurethane. The end result is a professional,
regged and watertight termination rated to full ocean
depth. The connector is available in 2, 3, 4, 6, 8,
& 10 pin male and female configurations together
with all specials with the same shell size.
Operational Steps
1. Ensure that the correct materials are
available for the planned job.
- The correct OM connector (e.g. OM6F)
- The correct "Boot" (e.g. OMBB)
- Adequate moulding material (e.g. CCPU 90 g)
- Primers (e.g. PR 10/PRM 10)
- Acetone for degreasing
- Crimp Sleeve and heating gun
- Soldering iron, solder, side cutters, cable strippers
and a small paint brush
2. Cut pigtail wires on OM connector
to approx. 2 cm from brass body. Trim back tapered
cable entry on boot until the cable is a snug fit
(approx. 0.5 mm less than a cable diameter.
3. Prepare cable to be connected by
stripping 3 cm off the jacket. Solder or crimp cable
wires to pigtail on OM connector and insulate using
crimp sleeve or electrical tape. Twist spliced conductors
together in same direction as lay in cable.
Degrease all moulding surfaces including
cable jacket, conductors and brass body with acetone
and allow to dry. Apply appropriate primer to brass
body conductors, cable jacket and neopren base of
connector with a small brush and allow to dry (approx.
30 min. at 20° C).
Do not touch primed surfaces after primer application.
5. Select the appropriate polyurethane
twin pack (CCPU 90 g for a single moulding or CCPU
216 g for 2 or 3 prepared mouldings).
Squeeze the twin pack until the inner
membrane ruptures and the two components can be mixed.
Work the pack vigorously by hand for about 30 seconds
to ensure thorough mixing. Cut off the corner of the
pack and squeeze the material into the boot as shown.
6. When the boot is full of material
slide it up the cable until it fits tightly over the
neoprene protrusion on the back of the connector.
Push the cable into the boot about 2 mm and wipe off
any excess visible polyurethane material. The connector
will be ready for use after 12 hours at 20°
C.
SAFE HANDLING PROCEDURES
Ensure barrier creams, gloves and a
clean, well ventilated work area are used to comply
with recommended health and safety procedures.
