Rules of repair of the electroextender
Now it is more and more made field electric devices and electric tools. These are electric drills, Bulgarians, fret saws, screw drivers, scissors - the list can be continued long. Often for their work extenders are required.
These goods in today's market are enough, from cheap to expensive.
Extenders which are more expensive can meet all necessary requirements and which are cheaper - hardly.
The basic reason of bad operation of the extender is the bad contact of the fork with the socket. But you do not hurry to throw out such extender, it can "be licked into shape".
I just have such copy: wire length three meters, section of the lake of 5 sq. mm, the cartridge of sockets on three consumers, "is in contact" badly.
For a start we remove the upper cover of sockets. There it is possible to see two rows of contacts which are two independent copper strips with roundings for fork electrodes inserted into special grooves that did not "part". At such design it is hardly possible to achieve the rigid and reliable electrical link.
We take out all these parts and we feed a liquid the network cord (if it is soldered). We take one contact block, we put with each other as they have to stand in the body. And places between roundings are wound with the adhesive insulating tape in 2-3 branch. Now these detalk are not scattered.
Further the ends of these contacts well obluzhivay tin by means of the soldering iron. Then we wind the regional fished ends with the copper single-core wire section 0.3-0.5 of sq. mm and we solder to the regional fished places.
Let's replace further and the wire of the extender with bigger section. I from recent mounting had piece of 2.5 m three-core and section 2.5 of sq. mm. Here I will also apply it to future extender. I involve all veins, so, one of wires will have bigger section. We smooth out tips and we solder to edges of contact units and the turned-out design, already monolithic, we insert on the place.
Did not close the cover yet, it is possible to check how the fork enters the socket, at some discrepancies it is possible to adjust and correct roundings in the socket. I assure you, the contact will be rather dense and the fork will be hardly inserted into the socket. Having convinced that everything works correctly, we close the cover. It was necessary to put the good fork on other end.
It is possible places which wound with the insulating tape, also to wind with the copper wire (bandage) and also пропаять. Insulating tape some kind of indicator: after long work it is possible to look at its state, having uncovered the socket.
And still small parting word: as "our" forks and "euro" differ in diameter of electrodes, for "our" forks define some place, having marked with any way. Here such there is the option on completion. This my personal, I think such handymen enough.
I photographed some moments for descriptive reasons if there is something not clear in the text
Here the socket on factory execution is so arranged
We wind average sites with the insulating tape
