The  objective  is  to  gain  experience in the processes involved in mounting both CRIMP and SOLDERED types of terminals to stranded  insulated electrical cable.

Crimp  type  terminals  are  used  almost  exclusively in low voltage applications in the Automotive,  Industrial,  and  Electronic  Industries.  The claims are that they will give more reliable service through the range of  demands  put  on  them,  standing up better than soldered types to the rigours of dust and grime, vibration, heat, and corrosive  materials  likeć
   solvents and chemicals.

A CRIMPING TOOL IS REQUIRED TO ASSEMBLE BOTH TYPES OF TERMINAL IN THE KIT.

INSTRUCTIONS

  1. Set  the  adjustment  of a wire stripper to suit the wire in the kit.
  2. Strip the insulation from 6mm of each end of the wire.
  3. Take the crimp terminal and push it onto the  end  of  the  wire, making sure that the wire is pushed right home.
  4. The  anvils  of the crimp tool are colour-coded with a dot.  Use the colour of the terminal to select the correct anvil.  Line up  the anvils  over  the  section  where  the bared wire is, and squeeze the handles hard, right together.
  5.  Move the anvils over the area where the insulation is inside  the terminal and crimp this area also.  The crimps should be in line with each other.
  6. Slide  the  heatshrink tube over the wire and mount the soldered terminal to the wire.   Anvils  specially  shaped  for  the  soldered terminal are usually found in the handles section of the crimp tools. Select the size to match the terminal and squeeze tightly together.
  7. Solder the terminal using resin-cored solder from the Kit.  Keep feeding solder into the joint until you see the shiny  molten  solder appear.
  8. When  the  joint  has cooled, slide the heatshrink tube over the joint and shrink with a hot air gun.
  9. Test the "CONTINUITY" of  the  lead  with  a  circuit  tester  or  multimeter.

TECHNOLOGY   NOTE

HEATSHRINK TUBE is made from Poly  Vinyl  Chloride (P.V.C.),  a  tough  plastic  that  is  resistant to abrasion and chemical attack and has  in-built  inhibitors  that  protect  it  from  Ultraviolet (sun's) rays.  Its electrical insulating property is excellent.   The  tubing  is  heated  and expanded in manufacture, and then cooled while still expanded.  PVC is a Thermoplastic which has a "memory".   When heat is applied to the tube, it "remembers" its former size and shape, and it  tries  to  return  to  that former state, squeezing tightly around the terminal.  Specification of Heatshrink is usually to shrink to  about  one-third of its expanded size.
