In the main body 10, for example, a main body guide hole 11 that guides the linear solder M is provided to extend from the rear end side toward the front end side.

  The tip portion 20 includes, for example, a hollow heat transfer body 21 formed so as to decrease in size from the main body portion 10 toward the distal end portion, and a heater 22 that heats the heat transfer body 21. ing. The heat transfer body 21 is preferably composed of a metal such as a pure cylinder or a copper alloy, for example. At the tip of the heat transfer body 21, for example, a melting hole 21 </ b> A for guiding and melting the linear solder M is formed. It is preferable that the melting hole 21 </ b> A is configured to come into contact with the linear solder M, for example. The length of the melt hole 21A is preferably about 2 mm to 3 mm, for example.

  The heater 22 is preferably disposed, for example, inside the heat transfer body 21 and may be provided on the main body 10 side as shown in FIG. 1, but from the position shown in FIG. May also be provided on the tip side. An example of the heater 22 is an electrothermal type. Although not shown, the heater 22 is provided with a conductive wire that connects the heater 22 to a power source, and can be turned on and off by a switch (not shown). Inside the heat transfer body 21 and the heater 22, a tip guide hole 24 for guiding the linear solder M from the main body guide hole 11 to the melting hole 21 </ b> A via the heat insulating member 23 is provided. The heat insulating member 23 preferably has heat resistance in addition to heat insulating properties, and is preferably made of ceramic, for example.

  The delivery mechanism 30 includes, for example, a rotating body 31 containing a one-way clutch disposed so as to contact the linear solder M inside the main body 10 and a part protruding from the main body 10. The pushing lever 32 that can be pressed toward the inside of the portion 10 and a conversion mechanism that changes the linear motion caused by pressing the pushing lever 32 into a rotating motion and transmits it to the rotating body 31 incorporating the one-way clutch. 33.

  The rotating body 31 incorporating the one-way clutch is configured so as to transmit the rotational force in the direction in which the linear solder M is moved toward the tip portion 20 and not transmit the rotational force in the opposite direction, for example. Yes. For example, a non-slip member such as a rubber sheet is disposed on the outer periphery of the rotating body 31 incorporating the one-way clutch so that the linear solder M does not slip, and the linear solder M is attached using friction. It can be moved. The outer periphery of the rotating body 31 incorporating the one-way clutch is configured to come into contact with the linear solder M through, for example, the opening 12 provided in the main body guide hole 11.

  The pushing lever 32 has, for example, a moving member 32 </ b> A that is extended in the extending direction of the main body 10 and is arranged to be movable in the extending direction with respect to the main body 10. For example, the moving member 32 </ b> A has a front end portion positioned in the vicinity of the rotating body 31 containing the one-way clutch, and a rear end portion protruding from the main body portion 10 and positioned behind the main body portion 10. At the rear end portion of the moving member 32A, for example, a flat plate-like pressing portion 32B is disposed. The conversion mechanism 33 may use friction or a wire, or may use a rack and pinion mechanism.

  The delivery mechanism 30 also preferably has a lever urging member 34 that urges the pushing lever 32 in a direction protruding from the inside of the main body 10. This is because when the pushing of the pushing lever 32 is stopped, the pushing lever 32 can be automatically returned to the position before the pushing. The lever urging member 34 is constituted by, for example, a spring. One end of the lever urging member 34 is disposed with respect to the main body 10, and the other end is disposed with respect to the pressing portion 32 </ b> B of the pushing lever 32.

  The pen type soldering iron 1 is preferably provided with a solder fixing mechanism 40 for fixing the movement of the linear solder M. When the linear solder M coming out of the main body 10 is pushed in the direction entering the inside of the main body 10, the rotating body 31 incorporating the one-way clutch of the delivery mechanism 30 rotates, and the molten solder is melted into the melting hole. This is because there is a risk of dripping from 21.

  For example, the solder fixing mechanism 40 is disposed inside the main body 10 so as to be rotatable with respect to the main body 10 and a non-slip part 41 made of a rubber ball or the like disposed so as to contact the linear solder M. It has the rotation support part 42 which supports the anti-slip | skid part 41 so that rotation is possible. Further, the push lever 32 is provided with, for example, a pressing rotation member 32 </ b> C that extends in the extension direction of the main body 10, moves in the extension direction together with the moving member 32 </ b> A, and presses and rotates the rotation support portion 42. Yes. The front end portion of the pressing rotation member 32C is positioned in the vicinity of the rotation support portion 42, the rear end portion is disposed in the pressing portion 32B, and the push lever 32 is not pressed, as shown in FIG. As shown in FIG. 3B, when the pushing rotation member 32C is not pressed by the pressing rotation member 32C and the pushing lever 32 is pressed, the pressing rotation member 32C is rotated by the rotation support portion. It is preferable that a part of 42 is pressed and rotated.

  Thereby, for example, when the pushing lever 32 is pressed, the rotation support portion 42 is pressed and rotated by the pressing rotation member 32C as shown in FIG. The linear solder M is configured to be moved away from the linear solder M so that the linear solder M can move. Further, the anti-slip portion 41 is configured to contact the linear solder M through the opening 13 provided in the main body guide hole 11, for example. For example, a non-slip urging member 43 that urges the anti-slip portion 41 to return from a state in which the anti-slip portion 41 is separated from the linear solder M to a state in contact with the linear solder M is disposed on the rotation support portion 42. It is preferable to be provided. The anti-slip urging member 43 is constituted by, for example, a spring, and one end portion is disposed with respect to the rotation support portion 42 and the other end portion is disposed with respect to the main body portion 10.

  In the pen-type soldering iron 1, first, for example, the pusher lever 32 is pressed to release the solder fixing mechanism 40, and the main body guide hole 11 and the tip guide hole 24 are opened from the rear end portion of the main body guide hole 11. A linear solder M is inserted therein. Next, the heater 22 is turned on to heat the melting hole 21A. Subsequently, the push lever 32 is pressed. Thereby, for example, the moving member 32A of the pushing lever 32 moves to the distal end side, and the pressing rotation member 32C moves to the distal end side, and the rotation support portion 42 is rotated to move the anti-slip portion 41 to the linear shape. Separate from the solder M and release the fixing. Further, the linear motion of the moving member 32A is transmitted as a rotational motion by the conversion mechanism 33 to the rotating body 31 incorporating the one-way clutch, and the one-way clutch is fixed and transmits the rotational force, and the linear solder M is moved to the tip side. Let The leading end of the linear solder M moves to the melting hole 21A, is melted by the melting hole 21A, and is attached to the soldering portion.

  When the pressing of the pushing lever 32 is stopped, for example, the moving member 32A and the pressing rotation member 32C are moved to the rear end side by the lever urging member 34 and returned to the position before the pressing. As a result, the pressing rotation member 32C returns to a state in which the rotation support portion 42 is not pressed, the rotation support portion 42 is rotated by the anti-slip urging member 43, and the anti-slip portion 41 contacts the linear solder M. Returning to this state, the movement of the linear solder M is fixed. The linear motion of the moving member 32A is transmitted as a rotational motion by the conversion mechanism 33 to the rotating body 31 containing the one-way clutch, but the one-way clutch rotates and does not transmit the rotational force, and the linear solder M moves. do not do.

Since the mechanism 30 is provided, the soldering operation can be performed while holding the pen-type soldering iron 1 with one hand and moving the linear solder M toward the tip 20 by the feeding mechanism 30. it can. Therefore, it is not necessary for the operator to bring the solder close to the soldering iron, the risk of burns and the like can be reduced, and safety can be improved. Further, since the soldering operation can be performed with one hand, workability can be improved.

  Furthermore, the tip 20 includes a hollow heat transfer body 21 in which a melting hole 21A for guiding and melting the linear solder M is formed at the tip, and a heater 22 for heating the heat transfer body 21. Since the tip guide hole 24 is provided inside the heat transfer body 21 and the heater 22 through the heat insulating member 23 to guide the linear solder M from the main body guide hole 11 to the melting hole 21A. The linear solder M can be melted and soldered in the holes 21A. In addition, the lands and elements before soldering can be easily heated. In addition, it is possible to suppress the melting of the linear solder M inside the tip guide hole 24, and more than necessary molten solder leaks from the melting hole 21A, or unmelted solder remains after soldering. It is possible to suppress dripping from the melting hole 21A.

  Furthermore, the delivery mechanism 30 is arranged so as to contact the linear solder M, and has a built-in one-way clutch that transmits a rotational force in a direction to move the linear solder M toward the tip portion 20. If the linear motion caused by pressing the push lever 32 is changed to rotational motion and transmitted to the rotary body 31 incorporating the one-way clutch, the one-way clutch is pressed by pushing the push lever 32. Is fixed, the rotational force is transmitted, and the linear solder M can be reliably moved toward the tip portion 20. Further, when the push lever 32 is returned to the state before it is pressed, the one-way clutch rotates and the rotational force is not transmitted, so that the linear solder M does not move, so that the linear solder M is used. Can be replenished.

  Furthermore, the anti-slip portion 41 is arranged so as to contact the linear solder M, and when the push lever 32 is pressed, the anti-slip portion 41 is rotated and separated from the linear solder M. By doing so, the linear solder M can be moved when the push lever 32 is pressed, and the linear solder M can be fixed and not moved when the push lever 32 is not pressed. Therefore, it is possible to prevent the linear solder M from moving when the push-out lever 32 is not pressed and being melted and leaked in the melting hole 21A.

  In addition, if the feeding mechanism 30 is provided with a lever biasing member 34 that biases the pushing lever 32 in a direction protruding from the inside of the main body 10, the feeding mechanism 30 automatically stops when the pushing of the pushing lever 34 is stopped. The pushing lever 34 can be restored to the position before the pushing. Therefore, a complicated operation is not necessary, and the soldering operation can be easily performed.
