    Those.

    I have one item, where one of the wires has pulled free of its plug. Male plug, if that matters. And, just so's I can't 'just buy another one and solder that in place'; Would ye believe This swine's at the four foot end of a Plug In Charger wire! 😬 Sealed lump at the other end. I sort this single wire, or the whole unit is binned.

    Is there any way I might sort this, please?

    JST XH series connectors? Google and see. They are pretty common on cheaper chinese stuff.

    Male is usually a solid square pin, maybe you can solder it back..? You could cut away the all the plastic and solder directly to the pins and set in epoxy.

    @whizbang;

    " JST XH series connectors? "

    Dunno, mate :| What ever I showed, above? That's just a random screen grab of what 'looks very much like' what I have in my gear.

    I did find a place that sells them. Certainly see what ye mean about the implication that they can differ! Wow! Now, ye have me wondering if the two items I have have the exact same types?

    Ooh!

    https://www.digikey.ie/en/product-highlight/j/jst/xh-series-connectors

    They've got the lot! Guess I'll have to now dig out the two bits of kit I have, needing them. (Charger and alarm, by the way. Just in case I start needing to discuss them further) Try to make sure of what sort(s) I have. Then, take it from there?

    Soldering? Yep. I'm the only guy in all of Co. Leitrim who Can't weld. Can't even Solder! Probably know a man who can though. 'Cake' certainly welds. See him any day now. I'll ask him.

    Okay; So, we might be able to get my mate to just mess about with a soldering iron? I was gonna ask 'how' they go in. That site suggests ye crimp their little attachments on the wire. Then stick that in a fresh, 'empty' plug?

    Now, I need to buy half a dozen of those. Possibly a 'crimping tool'? Oh. And empty boxes. And / or collar Cake? Thinking what I'm thinking?

    Only, Who or What should I ask for, please? Local Electricians don't really sound like the type? Dunno. We have a lad, fixes computers. Do these things occur in computers? Now, just thinking about the ubiquitous 'Technics' type shop we have in the village. Phones. Computers. I'm starting to like the sound of this! 😁

    Hell, yeah! Wouldn't That be the Ideal place to see? I was thinking of a nice, walk in TV Repair shop. Last saw one about forty years ago though.

    Sorry to have rambled. Ye called me away from, literally, explaining to a mate, on here, how I'm utterly dead on my feet now. Having worked 'hard' for three hours there! Then, I'd admonish him to wait till He gets to my bloody age! 😂

    But, yeah! Inspired! I'll have a word with Mo'. Thankyou!

    I have various sizes and wire count JST connecters that I'll be happy to send you on. Drop me a PM and I'll stick a selection of them in the post to you.

    If you're local to Limerick? I'll lend you the crimp tool too.



  • Registered Users, Registered Users 2 Posts: 3,692 ✭✭✭Stigura


    @banie01 Gentleman and a scholar, sir! Thanks!

    What I'll do, I'll get decent shots of what I'm dealing with, here. Maybe ye can recognise them and just match what needs matching? I'll have a go now. If the light's no good, I'll do it tomorrow and shoot ye them in pm 👍️



  • Registered Users, Registered Users 2 Posts: 19,168 ✭✭✭✭banie01


    I have a whole pile of molex and JST connectors, male and female so if I don't have an exact match? I should still be able to sort you a matching pair to get back up and running.

    No rush on getting a photo sorted, I'll be in the post office tmrw and on Monday anyway.

    It can be hard to figure out the pitch (spacing between pins) which is the important bit. The numbers are millimeters, you might recognise '2.54' as 10 pins per inch.

    My post office isnt open till monday, waiting patiently to post a late christmas present!!

    @whizbang & @banie01

    😮 Bloody hell, guys; I haven't had a thread This 'good' in a long while! Thanks! 👏

    Now; I've studied my plugs. Studied the ones on Whizbangs site. Wow! I'm So glad I asked!

    Hard to tell, with my eyes. But, mine Look like 2.54 - 2p. It's the 'Arrows' I couldn't see on any others. Ye reckon, lads? Here's mine, best I could get them:

    Plug Front.JPG Plug Back.JPG

    The site also mentions looking at ye Charger, for info? Ok:

    Charger.JPG

    Incidentally; I have absolutely No Idea which power setting I'm supposed to be on, for the thing I'm trying to charge! I just picked that as 'average ish'!

    Plugs though; Will those shots do? I could do it again, with a tape measure?

    Whoah! And, I've just tried to strip a bit of this wire? How in blazes to we deal with this stuff, so it gets a connection ~ if we ever manage to get it in the hole? Heh! I have my beloved 'Crimps' and that glorious set of pliers, to do it with? Somehow don't think they'll fit This though! 😦 😄

    What Is the craic, with these things, please? Do we poke them in? Stick those fancy crimps on them and poke Them in? Poke and solder? This is all getting frighteningly like threading a needle, isn't it? May have to call in a younger set of eyes!

    Sorry so many questions. These things are fiendish and fascinating!

    I have those connectors handy, both male and female. As for your charger settings, I always set it to a step below the battery charge setting. e.g if the battery charge capacity is 500mah I'll set it 400mah. I just like to work below peak capacity on tech that doesn't have smart charging or load/voltage detection built in.

    Regarding how to wire up to the prong/connecters. The "crimp" has 2 sets of wings, 1 for the wire & 1 for the insulation and much like making pancakes, the 1st effort is often a sacrifice 😂



  • Registered Users, Registered Users 2 Posts: 3,692 ✭✭✭Stigura


    @banie01

    " the battery charge capacity " 😶

    Chinese remote receiver unit? I randomly guessed it'd have one of these 18650 things in it? Got one here; 3000mAh 3.7V. All Chinese, to me, of course. Now I've told ye that? Still nothing. (Doesn't matter, till I can get these plugs on, anyway! 😂)

    Watched that vid. Thanks. Led me others ….. to Amazon ….. Got my eye on a soldering iron kit! Saw a glimpse of some dude soldering something. He's saying, " We heat both components and touch the solder to them, which …" Blob! Perfect little solder! Reckon I could manage that 🤔

    I realised the two, F ports, on this half? They're both to Charge the devices battery. Hidden inside). Only, One port is for this charger? The other port is just for some postage sized 'solar panel', set in the casing / other half, which is out there.

    Bottom line? I only Need this charger fixed. New, M plug, on the end of its wires! 😁 (I'm happy, because that removes the nightmare I'd realised was lurking in the other half of the unit! That could very well have killed this, in the water!)

    Only, that's still gonna need Crimpers (I only have the 'wrong' sorts). I can't remember where I got the soldering idea from. But, of course, I can't solder a plastic plug! Crimpers I shall get 🙂

    Surely a Wago connector is the simplest fix.



  • Registered Users, Registered Users 2 Posts: 3,692 ✭✭✭Stigura


    @Lumen; Hullo, mate! 😁 (Sorry, lads. I've been busy ferreting! It's all go, here 😎)

    Wago's, of course! Brilliant. I'd been gagging to ask about them. Entirely different project. Still all about joining wires though. I'm fascinated with the things!

    Trouble is. Lumen; They won't do, as a swift fix, on this particular job. I've just snatched a shot which'll explain more:

    Alarm Job.JPG

    See? It's the Solar Cell points I need to feed. Yeah? Obviously, they need male connectors, of their same type. Their own wires are beneath the plate. I'm just not going in there!

    Wago's though? Sexy as all get out, eh? I loved 'em from the moment I saw them! Only; I really, simply haven't yet been able to fathom quite how we'd use them 😐️ Only able to see them via this thing, see? Never actually picked one up and looked. It'd be brilliant, if ye could, please, shed a little understanding?

    I'm on Major Tom's, as we speak: " Inline splicing connector ". Looks, to me, like ye put two wires together. Contiguous flow. Okay. Cool.

    Only, next to that? " 221-2411 Terminal 2 Conductor ". Looks, for all the world, like same purpose? How do they differ, particularly? Next to Those are " Splicing Connector Conductor's ". What?!? 😱

    I want to stitch a yard of flex onto this thing? Which type of Wago should I now use, where I would have used an old Blocks and Screws deal and tape. (I wouldn't, actually. I'm not a savage. But … 😂)
