Abstract

[Technical Field]

Work shoes for various special purpose workshops including semiconductor industry

[Technical problem to be solved]

The resistance with constant resistance of 1MΩ, which is used to effectively discharge static electricity generated from worker's body, clothing, etc. to the semiconductor, is grounded on the insulation coated lead wire and placed on the upper surface of the insulation auxiliary outsole. Since the resistance and the lead wire are easily broken, it cannot be used for a long time, and when the resistance is damaged by the overcurrent, the resistance cannot be easily replaced.

[Summary of solution]

The operator works under the volume resistivity condition (current holding condition of 10 ⁶ -10 ⁸ Ω), which is the most suitable for the work that is damaged by the generation of static electricity in semiconductor chip manufacturing work, so that the static electricity does not affect the semiconductor and In order to effectively discharge the gas and to prevent the overcurrent in the workplace from flowing back to the human body, a resistance of 1MΩ that induces static electricity generated in the human body of the worker is installed outside the energized and cut-off working shoes.

Description

Energization, current blocking work shoes

The present invention is designed to apply electricity and cut-off operation to effectively remove static electricity generated by human body or external friction in various special-purpose workplaces including the semiconductor industry and to fundamentally remove the effect on the workers due to overcurrent of the workplace. It is about.

Conventionally, the work shoes for ignition in a special-purpose workplace were worn in the form of an oversized cover made of fiber fabric, but this has been released to the workplace without removing dust and static electricity displayed from the human body of the oversized wearer.

And by these means did not effectively remove the static electricity generated in the human body and clothes.

Due to this drawback, in Korean Utility Model Publication No. 94-5511, a plurality of carbon fine wires 10 are arranged and woven into a sole 4 formed of urethane or synthetic resin incorporating an antistatic agent, as shown in the accompanying drawings. It has been disclosed to form an energized working shoe made by adhering the insole 3 having) to the electrically conductive adhesive 5.

However, since the work shoes are fixed to the inner part of the sole 4, that is, the ignition part, by attaching the insole 3 as an electrically conductive adhesive 5, the static electricity generated in the body is finally transferred to the outside through the sole, that is, the lower part of the special workplace Although it can be discharged to the outside through the overcurrent of the workplace, the electricity is delivered to the worker as it is, there was a fear of causing a fatal injury such as the human shank.

In order to prevent this problem, the applicant filed Utility Model Registration Application No. 28199 dated September 5, 1996.

This allows 1MΩ to flow through the semiconductor without the influence of static electricity generated in the human body of the worker, and also effectively blocks even when overcurrent occurs in the workplace so that the overcurrent does not fall on the human body and discharges static electricity generated from the human body and clothes. The resistance of 1MΩ above is grounded to the insulation coated lead wire and placed on the upper surface of the insulation auxiliary outsole, so that the resistance and the lead wire can be easily damaged by the weight of the operator. If the resistance is damaged by the overcurrent, the replacement of the resistor was not easy.

Therefore, the present invention has been devised in consideration of the above problems, and its purpose is not to have a direct impact on the weight of the worker, such as the weight of the worker, and to be easily exchanged even if the resistance is damaged by overcurrent. To make it work.

In order to achieve this purpose, it was possible to solve the problem by installing a resistance of 1MΩ to induce static electricity generated in the human body of the worker outside of the energized and energized cut-off work shoes.

30: first binding hole 26: conductive metal plate

27: conductive second binding port 19: resistance

The present invention is as shown in Figure 1 to the accompanying drawings to solve the above technical problem.

An insole 3 having a work shoe upper 20 having a conventional shape and a carbon fiber 2 in which a plurality of fine carbon wires 1 are arranged and woven in a sole 4 made of a conductive material. In which the insulating pallet 21 is adhered;

The conductive first binding hole 30 and the conductive metal plate 26 installed to communicate with the inside and the outside of the upper 20 by placing a conductive electrically conductive pallet 25 having a predetermined size inside the upper 20. );

A portion of the second conductive fastener 27 is embedded in the sole 4 so as to protrude outward, and thus the conductive properties of the first and second fasteners 30 and 27 are respectively attached and detached. The lead wire 16 connecting the resistor 19 having a resistance of 1 MΩ is grounded between the third and fourth binding ports 28 and 29 to form an earth ring 31 covered by an insulator.

The energization of the present invention, the energization cut-off work shoes are the conductive pallet 25 or a plurality of carbon fine wires (1) which are in contact with it through the soles or socks by the static electricity generated by the friction of the human body or work clothes or the outside is arranged and woven The carbon fine wire 10 of the insole 3 having the carbon fibers 2 is energized from the conductive metal plate 26 to the conductive first binding device 30 through the conductive pallet 25.

At this time, the conductive first binding hole 30 is transferred to the conductive third binding hole 28, and the lead line 16 again leads through the resistance 19 having a resistance of 1 MΩ through the lead wire 16 again. The line 16 leads to the fourth conductive fastener 29.

As such, the static electricity that reaches the fourth conductive fastener 29 is grounded to the sole 4 made of an electrically conductive material through the second conductive fastener 27 fixed thereto. It is emitted through the outside.

Due to this action, the resistance 19 corresponding to 1 MΩ is maintained so as to maintain the state of the volume resistance (10 ⁶ -10 ⁹ kPa) which does not affect the semiconductor by static electricity such as a human body generated in the semiconductor chip manufacturing workshop. As described above, the electricity is supplied to the human body, thereby excluding the influence of the semiconductor on the semiconductor by the static electricity of the human body.

In addition, when an overcurrent occurs due to a short circuit or the like in the workplace, it is rather reversed to the worker at the workplace, which causes a great physical impact on the worker.

At this time, if a current of at least 1MΩ flows, the overcurrent of the floor of the work place is transmitted through the sole 4, and then through the conductive second binding hole 27 embedded therein, the conductive fourth binding hole (which is bound thereto). 29), the lead wire 16 is reached, but the overcurrent is blocked by reaching the resistance 19 of 1MΩ to maintain the resistance 10 ⁶ -19 ⁹ kΩ.

Eventually, the overcurrent of 1MΩ or more is cut off in the resistor 19, so that no more energization is possible, and the overcurrent is completely blocked by the insulation pallet 21 installed between the sole 4 and the insole 3, so that the worker The effect of overcurrent is no effect at all.

When the resistance 19 of 1 MΩ is damaged by such an overcurrent, the earth ring 31 attached to the conductive first and second binding holes 30 and 27 is removed as described above, thereby providing a new earth ring. By replacing with (31), it becomes possible to immediately energize and re-energize the energization blocking work shoes.

The energization and energization cut-off working shoes of the present invention can be used according to the needs of the operator by penetrating the conductive auxiliary plate 33 on a proper position on the auxiliary pallet 32 as shown in FIG. .

As described above, the conductive pallet 25 or the plurality of conductive pallets may be transferred through the conductive subplate 33 of the auxiliary pallet 32 in which the static electricity generated by the friction of the human body or the work clothes or the outside is brought into contact with the sole through the sole or the socks. The carbon fine wire 1 of the insole 3 having the carbon fibers 2 on which the fine carbon wires 1 are arranged is connected to the conductive first fastener 30 at the conductive metal plate 26 through the conductive pallet 25. ) Will be energized so that it can be used.

The present invention allows 1M 상기 to flow through the semiconductor without affecting static electricity, etc. generated by the human body of the worker, and also effectively blocks the overcurrent even in the workplace so that the overcurrent does not fall on the human body and occurs in the human body, clothing, etc. It can effectively discharge static electricity, and by installing the resistance of 1MΩ outside the energized and energized cut-off work shoes to induce static electricity generated from the human body, the load of the human body of the worker does not directly reach the resistance of 1MΩ and is also damaged. It is a very useful design that can take the change of 1MΩ resistor very quickly.
