View Full Version : Hitachi plug experts

I've crimped RJ-11, RJ-45, coax (compression and standard), and various other electrical connections.
I've never done the Hitachi style. I have my plugs from EC (http://electricalconnection.com/index2.htm) along with a brand spanken' new crimper.
Now, does anyone have some directions and photo's on how to do this? I can probably figure it out but would like to keep from wasting too many of the pins.

A picture is worth a 1000 words, but I do not have a camera on hand.
1.thread the wire through the plastic part.
2.strip the wire and place it on the pin, into the 'u' shaped part
3.optional. solder in place
4.now the crimper...it is a little counterintuitive but- place the open side of the 'u' into the most appropriate size of the 'u' side of the crimper tool, not the way it kinda fits, but with the open side of the pin 'u' towards the open side of the crimper 'u'
5. now as you close the crimper tool it will push the arms of the pin 'u' around the wire, when done correctly the arms will be bent around the wire with the bent ends of the pin 'u' seated tightly against the bottom of the tool 'u'. Look closely at the base of the crimper 'u' , it is not flat, it is a the shape that the crimped pin will be when finished.

Here's some tips:
the pin terminals go into the female half, the socket terminals into the male half. They go in from the outside of the plug/socket. The lineup at 90 degees into their slots.
Strip enough wire to a bit more than the length of the wire crimp but not the insulation crimp. Insert terminal into crimper and pinch enough to hold it while inserting the wire strands so they all go into the crimp area. Crimp.
You'll notice the crimper dies have two crimp areas. The larger area is for the insulation crimp. Make sure you put the terminal into the crimper with the outer, insulation crimp tabs in the larger die cavity.
Hopefully you have a few extra terminals to practise with. If so, practise first on an extra wire. The wire should not be able to be pulled out.
Crimping is a practised art so don't be surprised if you don't get it perfect the first time. If in doubt, do a bit of a tack solder on the wire strand ends only. Do not overheat.
Show a similar crimp terminal and what it should look like.

Thanks for the information. :)
