Description

The invention relates to the field of soldering, in particular, to the construction of a soldering iron for disassembling, for example, microradioelements, and can be used in electronic and electrical engineering.

The purpose of the invention is to simplify the changeover of the blade.

The drawing shows the proposed PA lnik mode desoldering, cut.

The electric rail contains a detachable housing of two parts 1 and 2 interconnected by means of a threaded connection 3. On part 1 of the housing a handle 4 is fixed to hold the heater through which the electric wire 5 and the hose 6 connected to a suction pump (not shown) are passed . Inside the case there is a movable element. ment 7 is movable along the axis 8 of the body in the directions 9 and 9.

, On the element 7 with a displacement along the axis 8 there are made recesses 10, by means of which the element 7 interacts with the ball retainer 11 attached to the part 2 of the housing. The latch 11 includes a ball 12, spring-loaded with respect to part 2 of the housing by the spring 13. On the element 7 there is a collection of solder 14 with side holes 15, connected by means of a tube 16 of a material not wettable by solder with a ribbed heating tip 17. On the element 7 on the side opposite to the location tip 17, placed additional heating tip 18. The tips 17 and 18 are missed in answer 19 and 20, respectively. At the same time in the hole

19, a sealing tube 21 is disposed, and a gap 22 is made between the tip 18 and the walls of the housing. At the tips 17 and 18 are located

5 heaters 23 connected to the electric wire 5.

The distance between the free ends of the tips 17 and 18 is equal to the length of the body and the distance between the recesses 10. The collection 14 of the solder is made detachable. In the guides 9 there are holes - nozzles 24, overlapped with a flap 25 mounted on the element 7.

Pa lnik works as follows.

When operating in the soldering mode, tip 18 is removed from the housing. In this case, air is sucked through the gap 22 and the holes 24 ,. which leads to cooling of the elements adjacent to the part to be stripped off and at the same time suction of gaseous products from the soldering point occurs. If necessary

25 to transfer the switch to desoldering mode, the tip 18 is pressed with the force required to move the ball lock 11 to the desoldering position, and the element 7 is moved along the axis 8 with the hand pieces 17 and 18 along the axis 8. In pesyjfbTaTe of this tip 18 is inserted into the body, and the tip 17 extends from the housing, and the flap 25 closes the orifices 24. Thereafter, the blade is turned by the tip 17 to the part to be unplugged. At the same time, the air is sucked off together with the molten solder through the tube 16 through the holes 15, and the solder accumulates in the solder collector 14. Switching to soldering mode is done by pressing the tip.
