Parts identification

GrahamM · Sep 23, 2023

Hi, I'm not an electrician and know nothing about electrical DIY. I'm looking for advice on parts I need to identify so I can buy the right things/tools. Am I in the right place?

Thanks

Thanks.
Top picture is the old wire. I pulled the clips out of the white connector. I guess I need new metal clips for the new wire. I don't know what they are called though. The old white connector seems intact. I can't find any marks or part numbers on either the metal clips or the board connector. I bought the yellow handed tool. Will this do the job of crimping the new clips onto the wires or do I need something else? I realize these are probably all really dumb questions. Thanks again for any advice.

Can you not use the contacts/wires you pulled apart, and join the other ends to cables as necessary?
The tool you have appears to be for stripping the insulation from American Gauge wires, and not a crimp tool.

Also the last but one pic seems to show tinned ends to the wires, as if prepared for soldering to a board or something. Are they just the other ends of the wires with the contacts on? You don't want to be crimping tinned ends!

Ah ok, maybe I have to strip the wires back then. They probably are supposed to be soldered. Other end of wire is a heater cartridge for 3d printer. Couldn't buy a replacement with white board connector already fitted so have to do it myself. They have to go into those metal clip things and into board connector. Probably wisest thing to go to an electrical shop actually. Thanks for your time

Identifying plug pins is a dark artform. It helps enormously if the plastic part of the plug has a name on it like Molex or JST for example. If I had to guess I'd say it's an SM series plug made by JST. You could try find an SM series spec sheet or catalogue and see it coincides dimension-wise with any of the female crimp terminal contacts listed.
