I am replacing all the cables in this ultrasound head (my daughter's beauty parlor/don't ask) as the insulation, shield and one wire have broken in one cable and all the cables are stiff presumably from heat near the ultrasound head.
Was wondering whether anyone has any idea how I could improve the strain relief/lessen the wearing of the cable(s).
Let me explain the photos:
Photo 1 - Here we see the ultrasound head with top shell
removed and the cable which is broken (arrow points just after
it's strain relief). The break occurs somewhere just after
what I named as the "coupling" as it couples the top and middle
shell. This cable as well as four other cables and the
polyurethane pipe pass through the flexible plastic conduit
which is strengthened/supported with steel wire as can be
seen on the photo. These cables/pipe pass tightly through the
conduit i.e. little space for movement. The plastic tie near end of the conduit
I presume both helps a little so there is less motion of the
cables and stops the conduit from moving back through
the coupling.
Photo 2 - Here we can see the break in cable and the
flexible spring like support for the whole cable (same
support is at other end)
There are traces of some type of grease along the
wires presumably for pulling the cables/tube through
(not looking forward to this) and maybe to lessen wear
in case of any movement.
What is strange to me is that although I see a slight wear on the
conduit at exit from coupling, I don't see / feel any abrasive
surface and the wires are quite tight in there not being able
to move - what could cause such a break in the cable and is there any
wise I could do to avoid or reduce reccurence ?
