I am looking for the right crimping tool for crimp contacts that are for .100" female housing. I have seen alot of different tools just don't know which one is the right one. Thanks guys and girls.

    I bought a crimper tool from Jameco that·is supposed to work with a range of wire gages from 14 to 28.· I don't have the Jameco part number but the package part number says HT-202A from H-Tools.· I tried crimping a pin (Jameco P/N 100765CB) on to some 26 gage wire and it just falls off.· I cannot physically squeeze it tight enough to make it work.· Just to check if the problem was operator error I went to my local electronics assembly house to have them show me how it's done.· They couldn't make it work either.· But they had a ratcheting type crimper that worked very well.· The trouble is they have had it for years and don't have a spec for it.

    I've looked at other ratcheting types but haven't purchased yet.· They run around $70.

    Have you looked into Ferrels?
    They're like the little things on the end of your shoelace (can't remember the funny name)....these ferrels go on to the end of wire and you crimp them on. So you actually get a more rigid surface to put in to WAGO blocks or phoenix connectors (those green blocks with the screw that pushes down on the wire).

    Excelite sells the crimper for a few bucks!!
    The crimp looks square on the end of the wire. Can buy different sizes.

    Matt - you are correct.... there is a special crimper for the female connectors that mate to the standard .1" spaced headers.· The key is to make sure that the connectors and the crimper are designed to work together.· I purchased a bunch of female connectors from jameco.com· they also sell the crimper... the nice thing is that they tell you which female connectors the crimper is designed to work with.

    for example, if you use Jameco Part 100765·female connectors that look like this,

    100765.jpg

    then you would use Jameco Part 99442 crimper.

    Jameco actually provides all this info for each of the female connectors and crimpers they sell.

    Some good info on crimping can be found here:

    These are the crimp connector and housing that I have. It seems that jameco doesn't have the crimping tool for this crimp connector.

    I checked an older Jameco catalog and this is what it recommends for the 0.1 inch KK type

    http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=227492

    I have one and it works okay, but it's a little large and clunky·for crimping the smaller KK terminals.

    Thanks RDL2004 for the link. How many tries does it take you to get the crimp right?

    You pretty much have to get it right on the first try, if you don't the connector is usually too messed up to re-use.

    Normally if I don't like the result the first time, I'll try to salvage it by soldering.

    I don't really think that tool I linked is all that good for the KK type, but any of the better ones are going to cost a whole lot more, and it can get the job done with a little practice and patience.

    If you've never really made crimped connectors before, try to learn as much as you can first, read that web page I linked to above and do a google search on "how to crimp".

    Hey Matt,

    I really like this simple crimp tutorial that Scott Edwards has on his web site here:

    http://www.seetron.com/lcd_an2.htm

    Scott shows just how its done and what·header pins·and·crimp tool he uses - he even gives the Jameco part numbers to make it easy.· Looks like the same crimp tool that others have mentioned.

    Tim

    Edit:·Forgot to mention that you·should look·toward the bottom of that page.

    This is the KK system. There are two different socket types that are quite popular. Both of the .025 diameter pin connectors shown above can be crimped with one crimping tool. GC/Waldon makes their model W-HR-1921 tool. It will crimp both the .062 and larger .093 diameter terminals for nylon pin and socket connectors. I bought my crimping tool for $12.99 at Frys.

    The pins and sockets are used for wire sizes from #22 through #30. My experience has been when using smaller than #22 stranded wire, apply a bit of solder to the wire end to "bulk it up" so it doesn't pull out of the crimp.

    I use the connector shown in Steve Joblin's post for robot point-to-point connections. I make my connections between .025 square pin headers I mount in my circuit boards. Then, these connectors are crimped and soldered to the ends of #24 stranded wire. I cover the connector with a bit of heat shrink tubing. This connection process allows for quick and fairly secure placement of wires on a board.
