How to Crimp Connectors | RobotShop Community

This is a little how-to guide on crimping connectors for various electronics projects. The art of crimping is sometimes a difficult one, but necessary for 1) reliable and 2) decent looking connections. Breadboards are nice for quick wiring projects but in the long run they are unreliable and look p

Thanks for info.

I find I get a stronger connection if I double over the stripped wire and run half of it under the insulated bit in the insulation channel. This way I have doubled over bit in the wire channel and the stripped conductor making contact along the full length of the bottom of both channels. It more difficult to pull the terminal off as it is then pulling against the grain of the wire strand as well as having to unloop the wire.

That 4-pin black plug housing looks like AMP part number 104503-3.

Thanks, couldnt find anything on youtube for this!

good one this crimping method has helped me to improve my crimping work

Here are some Jameco part numbers I have used:

100766 - Female Pins
145358 - Male Pins
103191 - 10 Pin Housing
100812 - 2 Pin Housing
159266 - Crimp Tool

The links to the Jameco catalog are broken. Since vendors tend to constantly change their websites, it’s probably better to simply mention part names and numbers instead of directly linking to their catalog.

Heya just wanted to give you a brief heads up and let you know a
few of the images aren’t loading correctly. I’m not sure why but I
think its a linking issue. I’ve tried it in two different internet browsers and both show the same results.

we found some images missing from the server indeed. We uploaded a bunch so the problem should be solved now. Let us know if some are still missing.

This is a great how-to. I find that sometimes the crimp over the insulation will actually pinch the wire and cause it to separate from the pin. Typically I eschew using the crimper and use smooth face pliers to wrap the insulation channel around the insulated part of the wire to avoid this problem.

Another good technique is to tin the wire before crimping, then reflow the solder after you crimp. This normally involves using a fine point on the iron and very fine solder.

Also, for Elmer Arguedas, I found the waterproof f-types to be no good. I use a fixed coaxial stripper like ht-302b and a hex crimper like ht-336g for rg-58. They work for 59 as well as crimp rg-6, however, you will need a stripper for rg-6. In a pinch, you can use a razor blade and measure your strips by hand, just be careful not to nick the wire or shielding!

can we crimp 4 wires in a d-sub crimp, For ex: 3 wires of 26 awg needs to be crimped in a 22-28 awg crimp, is that possible

@sharmila That’s potentially possible, but easier with multi-strand wire.
