Изобретение относитс к области пайки, в частности к электропа льникам , и может быть использовано при пайке изделий машиностроительной промышленности.The invention relates to the field of soldering, in particular to electric flax, and can be used when soldering products of the engineering industry.

Известен па льник, содержащий ручку и нагреватель, смонтированный в теплопередающей трубке, образованной двум полукольцами, обхватывающими нагреватель, и соединенный с па льным стержнем и ручкой посредством несущей трубки l.A steam bath is known, containing a handle and a heater mounted in a heat transfer tube formed by two half-rings encircling the heater, and connected to the steam core and handle by means of a carrier tube l.

Однако низка теплопроводность между нагревателем и теплопередающей трубкой возникает из-за отсутстви прижати между ними, поэтому температура нагревател намного выше температуры теплопроводной трубки, а допустима плотность тока в нагревателе низка. Нагреваема поверхность па льного стержн не прижимаетс к теплопередающей трубке.However, low thermal conductivity between the heater and the heat transfer tube arises due to the lack of pressure between them, so the temperature of the heater is much higher than the temperature of the heat-conducting tube, and the current density in the heater is low. The heated surface of the solder rod is not pressed against the heat transfer tube.

Известен также па льник, содержащий нагреватель, смонтированный в теплопередающей трубке, и конический па льный стержень 2.Also known is a steam rail containing a heater mounted in a heat transfer tube and a conical pallet 2.

Недостатком этого па льника также вл етс низка теплопроводность между нагревателем и па льным стержнем, а также между спиралью и корпусомThe disadvantage of this fuse is also the low thermal conductivity between the heater and the solder rod, as well as between the coil and the body.

из-за отсутстви прижати спирали к стержню и корпусу.due to the lack of pressing the helix to the rod and the body.

Цель изобретени - снизит температуру нагревател , повысить допустимую плотность тока в нагревателе и увеличить теплопроводность от нагревател к па льному стержню.The purpose of the invention is to reduce the temperature of the heater, to increase the allowable current density in the heater and to increase the thermal conductivity from the heater to the saline.

Это достигаетс уем, что теплопередающа трубка выполнена в виде This is achieved by the fact that the heat transfer tube is in the form of

o двух втулок, имеющих цилиндрические и конические поверхности сопр жени , при этом цилиндрические поверхности соединены -между собой жестко, а конические поверхности расположены o two sleeves having cylindrical and conical mating surfaces, with the cylindrical surfaces connected - rigidly between each other, and the conical surfaces located

5 с зазором, в котором размещен нагреватель .5 with a gap in which the heater is placed.

На чертеже показана конструкци па льника.The drawing shows the design of the flax pa.

Электропа льник содержит ручку 1, Electric flax contains handle 1,

0 несущую трубку 2, па льный стержень 3, нагреваема часть которого выполнена конической, и нагреватель 4, Нагреватель 4 состоит из однор дной спирали, намотанной виток к витку, 0 carrier tube 2, the steam rod 3, the heated part of which is made conical, and heater 4, Heater 4 consists of a single-helix coil wound to turn,

5 и тонких пластин изол тора 5.5 and thin plates of the insulator 5.

Claims

The heater 4 is located in the gap between the conical surfaces of the sleeves 6 and 7 connected with the aid of the thread 8. The inner sleeve 7 is fastened to the steam rod 3 with the help of thread 9. The current leads 10 installed in the groove II of the sleeve 6 are made of made of heat-resistant metal and insulated, for example, with glass tape. The sleeve 6 is installed in the carrier tube 2 up to the chimes 12 and is folded. Such an electrical design of the electric flax ensures that the heat transfer surface of the tube is pressed against the heating & 4. And the execution of the heated part of the steam rod is conical in contact with the surface of the internal sleeve of the heat transfer tube, and it is fully pressed together with the thread All this increases the thermal conductivity from the heater to the solder rod and reduces the temperature of the heater. 1 Claim of the invention The electric flax comprising a heater mounted in a heat transfer tube and a conical solder rod, characterized in that, in order to reduce the temperature of the heater, the heat transfer tube is made in the form of two sleeves having cylindrical and conical interface surfaces, while they are rigidly interconnected, and the conical surfaces are arranged with a gap in which the heater is placed.
