    Invaluable information! Thanks to this vid, I'm now a proud owner of a P300 Pin Insertion Machine and a 2161500 Benchtop Terminator. Had to take out a second mortgage on my home, but I was finally able to fix the right side speaker on my 1979 Honda Accord.

    It is quite true as said by Xavier, that twisting wire is not required. Many companies are adding this to their inspection check list. Many modern machine do not twist while crimping.

    Very disappointed that the important subject of whether strands should be twisted or not, is totally ignored.
    One thing I am certain about is that tightly twisting strands ensures totally unsatisfactory open barrel crimps, as demonstrated by the numerous tutorials on youtube. The wings need to be able to easily divide the strands into 2 neat bundles.

    Some additional information:
    For larger diameter stranded wire the AWG size indicated, if the diameter is measured to the outer most extent of the strands, will not give the exact diameter of the stranded cable, or be the same in comparing one stranding to another. Also, if there are many strands like on Class 5 or Class 6 (welding cable or high stranding Marine wire, all must be copper or copper core with either tin or silver plating) the lay of the windings also influences the measured outer most diameter. The important aspect of AWG sizing (current capability) is in equivalent circular mils (cross sectional area), after the crimp is made which eliminates the majority of the open space by distorting the circular cross section of the strands. So what matters is using the correct crimping die for the lug and wire used, such that the crimp essentially creates a solid cross section by distorting the circular strands.
    You should always make sure the copper wire strands are not oxidized after stripping, and if so, it should be cleaned (usually this is just wire roll end corrosion that can be eliminated by discarding the end foot of the roll. The crimp terminal wire crimp area should also be clean and without oxidation. For larger lugs (with inspection window) some users like to solder after crimping. It could be argued that if the correct liquid flux is used to make the solder joint at the correct temperature for the solder type, than there should be some flux cleaning action when the solder joint is made and any remaining space should be occupied by solder.
    For lugs and terminals for 8 AWG and larger diameter stranded wire hydraulic crimpers with a minimum of 8,000 Pounds force (15,000 Pounds is not uncommon for 3/0 and larger using a circular die) is used to completely compress and distort the round strands to eliminate any inter-strand spaces. For larger diameter lugs 2 AWG and larger, it is informative to do a test crimp and then cut through the crimp with a fine saw, fine sand the end and inspect the cross section under a stereo microscope. These test samples are periodically performed and provided to the customer if part of the contract.
    The video shows how the secondary wire insulation crimp should not distort the insulation or cut too far and make connection with the wire within. However, depending on the insulation type a slight indent to provide maximum grip is most often the best case for pull strength. Doing an individual crimp pull test is easy to do using a pull force gauge. If both the wire and insulation crimps are done correctly, both crimps will resist the pull force, and will be surprisingly strong even for small diameter wires like 18 AWG.
    If you are making electrical harnesses using crimp pins and connectors, after the harness has been made it is then tested. Before testing it is best to add a pin connection cleaner and lubricant like Deoxit D100 to the pins before the test. In this way when the test is performed the pins are cycled, cleaned (wiped) and lubricated. If the pins have been in inventory for more than three months, many times the testing procedure will call for the cycling of each connector three times before testing.

    Great video. So when you go to crimp, should a man twist his conductors together before inserting them into the terminal, or should he simply crimp with the conductors pointing straight out, just as they are naturally when stripped from the sheath without twisting them?
    Thanks

    • @fiver-hoo
      @fiver-hoo 3 роки тому

      A man should just immediately shove them in as hard as he can. A woman should gently caress each strand, slowly rub the conductor around the outside, then gently and firmly insert.
