We make a reliable probes for multimeter alone

Tell me, how often do you repair (change) test leads (ends) for your electrical appliances such as miltimetra? Personally, I have to travel this procedure about once every six months, until I decided to do a reliable self-ends. In this article I will describe the whole process of assembling reliable test leads.

We are preparing the necessary equipment

So in order to successfully complete the task we are with you will need:

1. Two ballpoint pens (or rather their body).

2. A pair of plug and needle contacts.

3. Shrink with building a hairdryer.

4. A flexible core wire and a solid wire. As the two pieces of flexible wire conductors MF-3 1.5 mm2 one meter in length were used. And one half-meter length of wire PV-1 cross-section of 2.5 square millimeters.

5. Soldering iron, solder, pliers, knife stationery.

So, everything you need is ready, you can start the production ends.

We do Probes

So, first of all warm up the soldering iron and ludim stripped ends of flexible wire and our connectors with you. With piece solid wire generally remove all insulation layer, and divide it in half ludim just one hand.

Next solder pin contact to the single-core hard wire.

Note. For high-quality heating and soldering the connector and solid wire solder, use a powerful 100 watts to heat the soldering point quality.

After this, take a pen, untwist and take out the rod from her. In doing so the cap is twisted hole so he could get through to you our flexible wire.

Then, instead of the hard wire rod inserted with one hand soldered connector sliced ​​closing cap and is metered rod length.

Bite off excess and solder to a measured end of the flexible wire. At the other end of the flexible conductor solder pin connector

Now take termosusadki and construction hairdryer

And isolating our with you solder joints as shown in the figure.

Now we tighten our you "handle" and check the performance of our with you new test leads.

Note. If after you have collected tips and "rod" comes out of the pen, it can be a place where you cut the plastic with a cap, in addition to fix the hot glue. This will provide a more secure fit.

conclusion

As you can see the production process is very simple and I took no more than one hour. And in the end I got quite robust and if necessary repair and suitable probes. If the article was useful to you, you will appreciate it Like. Thank you for your attention!
