This invention relates to an electric soldering iron that is highly safe and easy to maintain without the risk of electric shock.

[Conventional technology]

Various electric soldering irons have been provided in the past, such as an electric soldering iron (Japanese Utility Model Publication No. 53-47067) in which only the tip can be attached and detached without using any tools.

However, no iron tip, handle, or power cord that can be easily and safely disassembled and assembled without using tools has been provided.

For this reason, it has the disadvantage that it is bulky and inconvenient when carried, for example when stored in a tool box, etc., and maintenance is also troublesome.

[Problem that the invention attempts to solve]

The present invention provides an electric soldering iron that can be easily disassembled and assembled into the tip, handle, and power cord without using any tools, and is convenient to carry. , which is highly safe since there is no risk of electric shock during assembly, and is intended to facilitate maintenance.

[Means for solving problems]

In order to solve the above problems, the present invention consists of a iron part, a cylindrical handle, and a power cord part, and a threaded part is provided at the tip and rear end of the handle, respectively, and a rotating part is provided inside the handle. It is movable, has connectors on the tip and rear end surfaces, and is provided with a relay body that can be freely pulled out to an appropriate position in the tip direction, and the rear end of the iron part fits into the threaded part at the tip of the handle. A connector that fits the threaded part and the connector on the front end surface of the relay body is provided, and a connector that fits the connector on the rear end face of the relay body and a connector on the threaded part at the rear end of the handle are provided on the handle side of the power cord part. It is constructed by providing a slip-off prevention cover that is screwed together to prevent the power cord connector from coming off.

[Effect]

According to the present invention, when assembling, the relay body is first pulled out from within the handle to an appropriate position, and the connector at the rear end of the soldering iron tip is fitted into the connector on the front end surface of the relay body.

Then, the threaded part at the rear end of the iron tip is threaded into the threaded part at the tip of the handle. In this case, the relay body will be housed within the handle.

Furthermore, the connector of the power cord section is fitted into the connector on the rear end surface of the relay body.

Finally, the retaining cover is screwed into the threaded portion at the rear end of the handle.

As described above, the electric soldering iron of the present invention can be assembled very easily without using any tools.

Next, when disassembling it, the process is completely reversed to the assembly process, and it can be disassembled very easily without using any tools.

Note that even if you try to assemble the power cord part to the handle in the reverse order as described above, that is, to assemble the power cord part to the handle before the iron tip part, the power supply will not be removed because the relay body can be freely pulled out from inside the handle towards the tip end to the appropriate position. Since the connector on the cord part cannot be fitted to the connector on the rear end surface of the relay body, assembly cannot be performed.

Also, even if you disassemble the iron tip in the opposite order to the above, that is, if you try to remove the iron tip from the handle before the power cord, the relay body and power cord will rotate as the iron tip rotates, so you will not be able to disassemble it. is extremely difficult.

Therefore, even if the rear end of the power cord is connected to the power source, when assembling, the iron tip that is farthest from the power source is always assembled, and when disassembling, the power cord section that is closest to the power source is always disassembled. Therefore, there is no risk of electric shock, etc.

〔Example〕

In the drawings, a is a soldering iron tip, b is a handle, and c is a power cord.

The handle b has a cylindrical shape, and has threaded portions 1 and 2 provided at its tip and rear ends, respectively. In the case of the embodiment shown in the drawings, the threaded portion 1 has a female thread, and the threaded portion 2 has a male thread.

Further, inside the handle b, there is provided a relay body 3 which is rotatable and can be freely pulled out to an appropriate position in the distal direction, and a connector 4 is provided on the distal and rear end surfaces thereof.
5 is provided. The connectors 4 and 5 are electrically connected inside the relay body 3. In addition,
The outside of the handle b is shaped into a suitable shape, for example, a shape that is easy to grip.

In the case of the embodiment shown in the drawings, the relay body 3 is formed into a cylindrical shape with a smaller diameter than the inside of the handle b and is rotatable, and furthermore, the diameters of its front end 6 and rear end 7 are slightly larger, and the front end 6 and rear end 7 are slightly larger in diameter. The part 6 and the rear end part 7 are the handle b
By engaging with a protrusion 8 provided at an appropriate position inside the handle b, the relay body 3 can be freely pulled out from within the handle b in the distal direction to an appropriate position.

Next, the rear end of the soldering iron tip a is provided with a threaded part 9 that fits the threaded part 1 at the tip of the handle b, and a connector that fits the connector 4 on the tip end surface of the relay body 3. 10 are provided. The connector 1
0 is electrically connected to a heater (not shown) inside the soldering iron tip a.

Furthermore, a connector 11 that fits the connector 5 on the rear end surface of the relay body 3 is provided on the side of the handle b of the power cord part c, and is screwed into the threaded part 2 on the rear end of the handle b to connect the connector. A slip-off prevention cover 12 is provided to prevent the slider 11 from falling off.

In the case of the embodiment shown in the drawings, a power cord protector 13 is further provided on the power cord portion c to protect the handle b side of the power cord 14.

In the case of the illustrated embodiment, the connector 10 at the rear end of the soldering iron tip a is a male pin type, the connector 4 at the front end of the relay body 3 is a female socket type, and the connector 5 at the rear end face of the relay body 3 is of a female socket type. is a male pin type,
The connector 11 of the power cord section c is of a female socket type, and is designed to prevent the energized part on the power supply side from coming undone by the human body.

According to the present invention having the above structure, when assembling, the relay body 3 is first pulled out from inside the handle b to an appropriate position as shown in FIG. Connector 10 at the rear end of tip a
are fitted.

Then, the threaded part 9 at the rear end of the iron tip a is connected to the handle b.

Next, when disassembling, the process is completely reversed to the assembly, and as shown in the first figure, it can be disassembled very easily without using any tools.

Note that even if the assembly order is reversed to that described above, that is, if you try to assemble the power cord part c to the handle b before the iron tip part a, the relay body 3 will still be able to be pulled out from inside the handle b toward the tip to the appropriate position. As a result, the connector 11 of the power cord part c cannot be fitted to the connector 5 on the rear end surface of the relay body 3, and therefore assembly cannot be performed.

Also, even if the order of disassembly is reversed to the above, that is, if you try to remove the iron tip part a from the handle b before the power cord part c, the relay body 3 and the power cord 14 will rotate as the iron tip part a rotates. Therefore, it is very difficult to disassemble.

Therefore, even if the rear end of the power cord section c is connected to the power source, when assembling, the iron tip section a, which is far from the power source, is always assembled, and when disassembling, the power cord section closest to the power source is always assembled. Since it will be disassembled starting from c, there is no risk of electric shock or the like. Furthermore, maintenance can be easily carried out by disassembling it, and in some cases, it is only necessary to replace parts, which is economical.
