Materials: car cigarette lighter, network wire with a cross section of 1.5 mm2 – 1 meter, a wooden handle from a burnt-out soldering iron, terminals with an inner diameter of 3 mm -2 pcs, two male plugs for connecting to the output connector of the power supply, bolts and nuts M 3, cambric.
Tools: soldering iron, tweezers, solder, wire cutters, pliers, power supply for 12V * 5-10A, drill and drills.
Now we start assembling.
Step -1 . We completely disassemble the body of the car cigarette lighter. Everything is shown in the photo.
We only leave the spiral with the ceramic washer.
Brass strip size 5 * 30 * 0.5 mm with a hole in the center, bend a ring with a diameter slightly less than the outer diameter of the spiral.
Then we put this ring on the outer circumference of the spiral. See photos.
Step -2 . In the center of this ring, using a nut and an M3 bolt, we attach a terminal in which the power wire will be crimped and soldered. The center of the spiral is attached to the ceramic washer with a small pin.
The positive power cable must be connected to it. We bite off the center of the round terminal with pliers and with pliers we squeeze it under our pin.
Step -3 … We drill a metal tube, which was fixed on a ceramic washer, into a lower hole in it up to 6 mm. We insert this tube up the wooden handle of the soldering iron, it fits there very tightly. We pass the network wire through the handle. We crimp the upper ends of the wire in our terminals.
Solder the male plug to the second ends of the wires to connect to the power supply.
Step-4 . Superglue the spiral with a ceramic washer to the top of the metal tube.
our soldering iron from the 12V power supply, and we check the operation of the device Shown in the photo.
