Sockets for soldering into PCB, intended for clasping and releasing one wire only


DougF VK4OE
 

Greetings to all readers!

First of all, does anyone know the electronics industry name given to small single-conductor 'sockets' which are usually soldered into a PCB, designed to mechanically clasp a stiff wire (c. 0.7 mm dia.) and later to release that wire as whatever that wire is connected to is pulled away from the PCB?

I have seen such things in some boards taken from pieces of HP test equipment where there is a small 'daughter' board fitted to the parent board but still able to be removed from it.

Discovering the 'normal' name given to these is a first step towards possibly acquiring some....and the obvious next question is whether anyone knows a current source for this type of item....

Thanks in anticipation,

--Doug Friend, VK4OE.

When I was repairing boards we used to call them ‘Harwin sockets’, a single gold plated socket that was soldered directly into a hole in the PCB. Would take a fine wire, resistor lead, or IC pin.
I believe they are Available from Farnell.

If you only need one or two, you can take the pins out of turned pin DIL sockets.
A bit of heat and they push out.

The ones I like are the Wago ones, they use a spring loaded thing to hold the wire, so you just press down on the little plastic lever to release the wire. Quite robust really.

Greetings to all readers again, and thanks to those folk who have pointed me in at least one good direction on this subject.

Attached are two mechanical diagrams of two versions of the Harwin company's "1-way straight through-hole PCB connector contact" as found on RS Components' and Element 14/Farnell's web pages.

From those drawings it is apparent that one species is intended for a wire diameter of approximately 0.5 mm whilst the recommended wire diameter for the other one is approximately 1.0 mm.

To complicate my situation, the measured diameter of the pins on some OCXOs which I have and which have caused me to go searching in the first place, is 0.7 mm, right in between the recommended wire diameters of these two Harwin products.  I am guessing and hoping that the ''3163' connector intended for a wire of 1.0 mm diameter will not leave a 0.7 mm diameter floating around in mid-air.....the inserted wire should still be in contact, but not as firmly clasped as a 1.0 mm diameter wire would be.  Any comments about that?

The down-side of selecting this '3163' version is that RS Components' minimum order size is 100 units....whereas the smaller '3153' is a little over half the cost and the minimum order is only 25 units.  In this respect, Digi-Key do better deals than RS or Element-14/Farnell.

Thanks for your further consideration of this issue.

Cheers and 73,

--Doug Friend, VK4OE.

p.s.  I have just discovered that Harwin also make an intermediate sized 'H8504' connector, and Digi-Key have 9K+ in stock.

Amateur assembly tolerances will usually ensure that an undersize pin is sufficiently off-centre to make contact. (Obviously not reliable for long-term use, but usually OK for something like a component test jig.)

As someone else suggested, a cheaper route would be to buy turned pin IC sockets such as RS part number 813-115 and extract the individual pins. By cutting off the pin and mounting through the board these can be fitted in the same way as Harwin sockets.

Hi Doug,
What sort of cost are we talking about? I was thinking if only a few were required, then they could be
gleaned from an old bread board like S-dec especially if you have a damaged one lying around.

Thanks for that suggestion, Colin.

I think that those 'pins' in machined IC sockets are specifically designed for clasping 'wires' (IC pins) that are considerably smaller than what I'm looking at and thus would not be a good proposition.

I am happy that  I have now sought out and ordered 'sockets' designed for my immediate needs.

Hi All

I have a lot of skelleton turned pin IC sockets which can be dismantled from the holder without the need to sacrifice plastic IC sockets. If anyone wants any, let me know.

G'dday John.

I purchased relatively small numbers of three different sizes of these 'connectors' from Digi-Key, a total quantity (including some other items as well) which allowed for 'free' shipping of the order.  Shipping can be an expensive add-on....

The 'socket' size which takes 0.7 mm wire were around AUD $0.50 each; the size which takes 1.0 mm wire were around AUD 0.75 each; and the size which takes 2.0 mm wire were just under AUD 1.00 each.  I'm sure that if I was purchasing 100s and 1000s of them, the prices would be considerably less, but my needs are modest.

And I don't presently have any old 'junque' which has similar sockets and, even if I did, there would always be the probability that it/they is/are not the right size for my current project's needs.

Cheers and 73,

--Doug, '4OE.

G'dday Doug,
I've bought stuff from Dick Smith in the past when I've been in Oz, but I've got a feeling they no longer
exist. They were useful for buying all sorts of connectors & things including rechargeable batteries to power my FT-817 -
easier to do that than face awkward questions in Dubai. If they were confiscated on the way back it was no great loss.
Having said that I did manage to buy some really good batts. for my camera in a battery specialists shop in Albury
last time I was there.

Tnx fer the update Bob,
It prompted me to look at their solar charge controllers. I bought some cheapo Chinese
ones ( all that came up in a search at the time) Two have failed; the third is still in its box until I re-mount the
panels on the roof. I'm wondering if it is worth the bother & should I try to order one from Dick Smith.
