Abstract

PURPOSE: A soldering iron is provided to effectively prevent electric short by insulating an electric contact point between wire rods with an insulting oxide film. CONSTITUTION: A soldering iron(1) comprises an insertion recess composed of a heater insertion portion, which is formed on the rear end of an iron tip(20), and a temperature sensor insertion portion, which is formed on the front end of the iron tip. The inner diameter of the temperature sensor insertion portion is smaller than that of the heater insertion portion. A temperature sensor is inserted in the temperature sensor insertion portion, contacting the inner peripheral surface of the temperature sensor insertion portion.

Description

Soldering Irons {SOLDERING IRON}

The present invention relates to a soldering iron.

In the case of heaters of very small soldering irons, the iron tip itself is very small, so that the spacing between the coil-shaped wire rods is considerably smaller than that of the normal soldering iron. This caused a problem such that the wire rods are in contact with each other, such as an electric short or disconnection. In order to solve such a problem, when a large distance between the coils wound in the coil shape is set, a problem occurs in which heat is conducted to the handle of the soldering iron.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and provides a soldering iron that is easy to work by being configured in a very small size and effectively preventing electrical problems including electric shorts, heating quickly, and maintaining a temperature suitable for soldering operations. It aims to do it.

A soldering iron tip for melting the solder at the tip, an insertion recess having a substantially cylindrical shape formed along the leading end at the rear end of the soldering tip and opening toward the rear end side, and formed in a coil shape, the surface being insulated oxide film A soldering iron, characterized in that it comprises a heater which is covered with a heater and inserted into the insertion recess.

Electrical troubles can also be easily prevented. In addition, it is possible to obtain a soldering iron suitable for an operation that can hold the handle for a long time during the soldering operation. In the soldering operation, a soldering iron capable of maintaining a suitable temperature desirable for the soldering can be obtained, and as a result, the soldering operation becomes easy.

Figure 2 is a cross-sectional perspective view of the tip of the iron in the present invention.

In the soldering iron, the insertion recess includes a heater insertion portion provided at the rear end side of the iron tip and a tip end side of the iron tip.

In addition to the diameter of the heater insert is set to be smaller than the inner diameter of the sensor is inserted into the temperature sensor insert,

A detectable temperature sensor is inserted and the temperature sensor is in contact with the inner circumferential surface of the temperature sensor insert.

It is right.

Thereby, the temperature of the iron tip can be detected preferably. Therefore, the iron tip is heated by the heater inserted into the heater insert.

In this case, it is possible to provide adequate power to the heater to maintain the iron tip at the desired temperature. Therefore, it is desirable for soldering during soldering operation.

Soldering irons can be implemented that can maintain the proper temperature, resulting in easier soldering.

A cylindrical body having an outer diameter set smaller than the inner diameter of the temperature sensor insert in the soldering iron is inserted into the temperature sensor.

The temperature sensor is inserted between the outer peripheral surface of the cylindrical body and the inner peripheral surface of the temperature sensor insertion unit.

Is preferred.

In this case, the temperature sensor is properly fitted and fixed, and the temperature sensor insert is firmly in contact with the inner circumferential surface of the temperature sensor insert so that the temperature of the iron tip is

The degree can be detected effectively. Therefore, when the iron tip is heated by the heater inserted into the heater insert,

Proper power can be supplied to the heater to maintain the temperature. Therefore, during the soldering operation, it is necessary to maintain a suitable temperature suitable for the soldering.

A soldering iron can be implemented, which results in easier soldering.

The manufacturing method of the soldering iron of this invention is a manufacturing method of the soldering iron provided with the iron tip which melt | dissolves solder at the tip, The said phosphorus

An approximately cylindrical insertion yoke formed along the tip from the rear end of the pharyngeal tip and opening toward the rear end inside the two tips.

Forming a portion, and forming a heater in which the insertion portion is inserted into the iron-chromium-based metal containing aluminum in a coil shape.

And the heater formed in the coil shape in a furnace at a predetermined temperature for a predetermined time to oxidize at a high temperature.

The key is used to insert the high temperature oxidized heater into the insertion recess and to sense the temperature of contact with the inner circumferential surface of the insertion recess.

It includes the process of raising the branch.

In this case, in the wire rod having heat resistance, the electrical contact between the wire rods is insulated by the insulating oxide film. Accordingly, the wire rods

Even in the case of contact with each other, an electric short can be avoided, so that the distance between the wires formed in the coil shape can be narrowed.

All. In addition, electrical troubles such as disconnection can be easily prevented by the insulating oxide film. In addition, the temperature sensor is inserted in the recess

Since it is provided in contact with the inner circumferential surface, it is possible to effectively detect the temperature of the iron tip.
