Sumitomo 110 Crimping Help Page

First strip all wires 'just right'. The strands should stick beyond the wire crimp area slightly. Practice crimping first on some extra wire and terminals.

Insert the terminal in the crimper so that the wire crimp area will not be crimped at the end towards the insulation crimp. This will give a flare on that end so that the wire strands are not cut. You can see this flare on the photo above on the wire with the finished crimp.

Insert the wire into the crimper until you feel slight resistance as the insulation comes up to the wire crimp area. Be careful as the wire strands go into the wire crimp area that all strands go in and are not bent back.

Male terminal going into the connector. Line up the terminal with the locking tab shown below towards the lock tab channel in the next photo.

Female terminal going into the connector. Again, line up the terminal with the locking tab towards the lock tab channel in the photo above.

Before inserting all the wires with crimped terminals, ensure that you have the wire colors lined up correctly. Below you see the black will meet the black.

Insert carefully making sure the pins are entering the female terminals. Do not force them if they resist you likely have bent the pins slightly and will have to manually adjust them with a small screwdriver until they mesh. A good crimp will not bend the terminals when crimping, and they will insert and stay straight for easy connection.

No Crimper:

If you have no crimper you can carefully bend over the crimp tabs onto the wire strands and the insulation, then solder on the end close to the wire strand ends. Do not overheat or you'll melt the wire insulation. You only need a bit of solder. Heat the wire crimp area near the end of the wire strands, then touch with a bit of resin core solder. Solder will wick up into the crimp area, you don't need to have a blob of solder, just a small amount will do.

Crimping is an acquired art and requires a good crimper and practice. Always order extra terminals so you can perfect your crimp/solder method before working on the actual installation wires.

I sell good crimpers here.
