When a tunnel, subway, or building structure is dismantled with explosives, excavation works are carried out using industrial explosives when excavating basic rock foundations of civil structures, rocks such as quarries and mines. Explosives used to prevent safety accidents are very insensitive to explosions and are manufactured not to detonate on their own. Therefore, in order to detonate industrial explosives manufactured in this way, a primer acting as a detonator must be used. That is, in order to detonate the industrial powder, the detonator is detonated from the ignition device (blaster), and then the industrial powder is detonated and detonated to break down and destroy the rock.

As such, as a means of detonating the explosive, a blast line blasting, an electric primer blasting, a non-electrical primer blasting, and an electronic method are used.

The primer detonator 1 according to the present invention can be protected by the outer cover 3 and the cover 5 as shown in Figs. 1 and 2 (A), and if necessary, ignition a part of the outer cover 3 It can be described as a structure or configuration in which a portion 7 is formed, and a portion of the outer shell 3 has a wire 71 through which additional electricity required for blasting is input.

The ignition part 7 may have various shapes, and when the signal tube 88 used for the non-electric primer is used as shown in FIG. 2(B), it is formed to extend further from a portion of the outer shell 3 and inserts therein 9 ) Is formed. Here, the signal tube 88 or the gunpowder 89 can be used to be in contact.

That is, the inside of the outer shell (3) is a PCB substrate 25 is accommodated, it is a primer detonation device (1) characterized in that the discharge electrode 31 is formed on a portion of the PCB substrate (25).

If necessary, an electrode portion 25 is further formed on a portion of the PCB substrate 25, and a discharge electrode 31 having a discharge or spark function is formed on a portion of the electrode portion 25.

The purpose of the primer detonator 1 of the present invention can be achieved even by simply designing and manufacturing the discharge electrode 31 on a part of the PCB substrate 31. This is because the PCB substrate 21 is made of various materials such as soft, vinyl, and solid materials.

The PCB substrate 21 is characterized in that the coating layer 13 is formed of a waterproof or anti-corrosive, non-conductive adhesive or plastic or silicone material or material.

In this case, the discharge electrode 31, which naturally discharges or sparks, prevents the coating layer 13 from being formed.

4 is a cross-sectional view taken along line A-A in FIG. 3.

6 is a view showing a state of using a safety wire as a ground wire.

A wire 71 connecting the electricity supplied from the outside is connected to the PCB substrate 21 so that various electronic components 41 such as resistors and capacitors can be connected in parallel. In addition, the diode 51 may be connected to the discharge electrode 31 in the reverse direction. At this time, the zener diode 51 is preferred.

The zener diode 51 or the diode has a function of blocking a constant voltage from flowing to the reverse voltage.

The diode 51 is composed of a semiconductor p-type and an n-type junction, and conducts when the pn junction is forward, and has a characteristic of blocking the reverse direction of the pn junction. And even if a voltage is applied in the reverse direction of the pn junction, the current does not flow and is in a blocking state. When a reverse voltage of a certain value or more is applied, it increases rapidly due to the Zener effect, resulting in almost zero operating resistance. This phenomenon is called Zener breakdown, and the voltage at which breakdown occurs is called the Zener voltage.

A structure capable of discharging to the discharge terminal 31 with the Zener voltage and the current flowing through the Zener breakdown is preferable.

The reverse diode 51 is secured by blocking a constant voltage flowing from the outside.

In addition, one line of the diode 51 is separately provided with a safety line 81 extending to the outside.

It is configured to short-circuit between the discharge electrodes 31 using the safety line 81.

At this time, it is sufficient to use a short wire 82 or to connect or short-circuit the electric wires 71 and 71' as shown in the drawing.

When the discharge electrode 31 is short-circuited in this way, the discharge electrode 31 is not discharged from thunder or lightning, lightning, static electricity, or an abnormal current or voltage flowing from the outside to ensure safety.

In addition, when the other line of the reverse diode 51 connected to the discharge electrode 71 is connected to the discharge electrode 31, the safety line 81 extending in parallel is connected by installing a ground rod 85 on the ground or underground in the field. It is possible to securely manage the site by measuring or observing the connection state of the electric wire 71 by testing or measuring at a remote location while ensuring safety or checking or observing the test 100. In addition, when it is necessary to continue blasting, the earthing rod 85 is continuously installed in the soil or the basement to connect the extension line 81 to use it as an electrical neutral point to maintain a common earth ground between the site and the remote tester 100 to safely site the site. Management and status measurement and management are convenient. Even if the distance between the site and the place to be managed is far, the test is conducted while ensuring the safety by testing at a remote site, such as whether the primer detonator 1 is well installed, in good condition, or in a safe state in consideration of ground resistance. And it helps to conduct and supervise the construction such as work progress and blasting.

In particular, in rainy weather or when it is raining, lightning or lightning, thunderbolt weather or surroundings of high voltages or power transmission towers, radar bases emitting strong electromagnetic waves, etc. Construction can proceed. In addition, it is easy to carry out and manage the blasting construction safely and is beneficial.
