Crimp Splice Housing
The
crimp splice housing is designed to protect the Norland Optical
Splice and provide full cable strength when splicing either
simplex cable or duplex zipper cable. Cable strength is achieved
by crimping the Kevlar strength member fibers between a metal
collet and the central housing. Shrink tubing is added to
the ends to provide additional strain relief and a weather
tight seal.
This device requires a hexagonal
crimp tool for 1/4" stock such as a Daniels HX4 with
Y205 die. Final crimp diameter is 0.213". It also requires
a heat gun with temperatures to 125°C.
Assembly Procedure
A. Before making splice.
1. Insert one shrink tube and
one collet on each cable section. Slide these pieces up out
of the way. Slide central housing onto one of the cable sections.
2. Strip 2 inches of outer
cable jacket from each cable. Fold Kevlar fibers back out
of the way of the buffered fiber.
3. Strip buffer coating off
each optical fiber and cleave to give approximately 1/2"
of bare fiber extending from buffer.
4. Remove additional outer
cable jacket to give a total of 1 3/4" of optical fiber
extending from jacket.
5. Complete splice following
splice assembly procedure.
B. After splice is completed.
1. Start with the collet which
is on opposite side from central housing. Slide it down to
the end of the cable. Split Kevlar into two equal bundles.
Push collet 1/4" forward over Kevlar and slip Kevlar
to the back of the slots on collet. Pull Kevlar snug so that
cable end is flush with the back of the slots. Fold Kevlar
back and hold on collet.
2. Still holding collet and
Kevlar, slide central housing down onto collet and Kevlar.
Push cable and collet further into housing until Kevlar from
opposite cable appears at opposite end.
3. Pull kevlar out. Split into
two equal bundles. Slide second collet forward until it is
about 1/4" forward over Kevlar. Slip Kevlar into back
of slots on collet. Pull snug and fold back and hold on collet.
4. Slide central housing back
down over second collet. Do not tug on cable. If fit is tight,
gently push collet into housing while pulling on cable at
other side. Adjust both collets so they are equidistant from
ends of housing.
5. Crimp central housing to
collets. Leave 1/16" lip on end of housing. Trim excess
kevlar off.
6. Slide shrink tubing over
crimp area. Shrink down using low heat (125°C) until adhesive
inner wall melts and bonds to cable. Be careful not to melt
cable insulation.
