Description
Technical field
The utility model is related to explosive, specifically a kind of detonating needle.
Background technology
Blasting system is mainly by initiator+electric wire+detonating needle+preposition safe detonator+propagation of explosion Nonel detonator.
Low pressure is switched to high pressure, high-frequency pulse current by initiator bulky capacitor and high-power switch tube, and voltage is reachable
Then detonator detonating needle is connected on initiator by 1300v by blasting wire, with realize electric energy is remotely conveyed to lead it is quick-fried
Pipe detonating needle fires detonator propagation of explosion.
Detonating needle is front end, and initiator is rear end, and energy is released by rear end initiator, reaches front end detonating needle, quick-fried leading
Electric spark is generated in pipe, to realize the long-range percussion of detonator, improves the reliability remotely fired.In order to protect detonating needle,
The preposition detonator of one section of 15m can be set per separate explosion, detonating needle is arranged in home.
Detonating needle conductive structure is mainly made of two electrodes, and the metal circular tube of detonating needle is an electrode, inside pipe
Plain conductor be another conductive electrode, between the two poles of the earth are insulated by inner lead insulating layer.The syringe needle insertion of detonating needle is led
It combines closely with the explosive of detonator in booster.Since the distance between detonating needle the two poles of the earth are in 2mm, high pressure is exported in initiator
Under the action of electricity, air breakdown between two electrodes is caused to generate electric discharge phenomena, generated in discharge process high temperature excitation lead it is quick-fried
The explosive charge of tube wall, this explosion enter Nonel detonator, and excite Nonel detonator quick-fried along pipe propagation of explosion to its end
It is fried.
The problem of detonating needle exists in use at present cannot be used continuously after igniting a detonator.
1, non-serviceable main cause is detonating needle when exciting priming in detonator, and electric discharge high temperature is made between the two poles of the earth
At pipe surface electric injury, while during explosive initiation, will produce high temperature causes the syringe needle of detonating needle to black, conductivity pole
Normal use next time cannot be met by drastically declining.
2, non-serviceable second at a high temperature of detonation the reason is that can cause the insulating layer between two electrodes to damage,
It is short-circuit between two electrodes, next step use can not be carried out.
3, an electrode of the pipe as detonating needle, the connection with lead are squeezed mainly by the gap of plastics grinding tool,
Lead can be caused to be contacted with pipe after the deformation of plastics grinding tool unreal, be unable to ignition charge.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of detonating needle, the repetition which can solve detonating needle makes
With, ignite it is reliable.
In order to solve the above technical problems, the utility model uses following technological means：
A kind of detonating needle, including box body, the interspersed conducting wire being fixed in box body of setting, the conducting wire are divided into anode and connect
Line, negative terminal, positive terminal, negative terminal are the Cu alloy material of resistance to electric injury, and positive terminal, negative terminal are equipped with
High temperature resistant, erosion resisting insulation layer, positive terminal and negative terminal by box body the mutually isolated introducing box body in one end, positive terminal with
Negative terminal is mutually intertwined in the other end of box body in twisted shape.
The beneficial effects of the utility model are：
（1）After the pipe of detonating needle is removed, mounting process is simplified, while avoiding the contact between conducting wire and pipe
It is bad to cause to virtually connect, it cannot reliable exciting explosive.
（2）Insulating materials uses heat-resisting material, avoids caused by high temperature that short circuit cannot use between the two poles of the earth.
（3）Conductive material has used Cu alloy material to avoid electric injury, unlimited number of can use.
（4）While technique is simplified, reliability greatly improves, and may be reused, and greatlys save cost.
It is further improved as to the technical program；
A diameter of 1.5mm of the positive terminal, negative terminal.Above-mentioned setting can meet wanting of using infinitely
It asks, while material will not be caused to waste.
The alloy material is the black alloy of copper silver.
The thickness of the insulating layer is 1mm.Above-mentioned setting makes insulating layer have preferable insulation performance, meanwhile, in height
When pressure, and it can be discharged with ionized air.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Reference sign：1- positive terminals；2- negative terminals；3- box bodys.
Specific implementation mode
With reference to embodiment, the utility model is further illustrated.
Referring to Fig. 1, a kind of detonating needle, by box body 3, the interspersed conducting wire composition being fixed in box body 3 of setting；Conducting wire is divided into just
Pole wiring 1, negative terminal 2, positive terminal 1, negative terminal 2 are the Cu alloy material of resistance to electric injury, positive terminal 1, cathode
Wiring 2 is equipped with high temperature resistant, erosion resisting insulation layer, and positive terminal 1 is with negative terminal 2 by the mutually isolated introducing in one end of box body 3
Box body 3, the other end of the positive terminal 1 with negative terminal 2 in box body 3 are mutually intertwined in twisted shape.
A diameter of 1.5mm of the positive terminal 1, negative terminal 2.
The alloy material is the black alloy of copper silver.
The thickness of the insulating layer is 1mm.
The advantageous effect of the present embodiment is：
（1）After the pipe of detonating needle is removed, mounting process is simplified, while avoiding the contact between conducting wire and pipe
It is bad to cause to virtually connect, it cannot reliable exciting explosive.
（2）Insulating materials uses heat-resisting material, avoids caused by high temperature that short circuit cannot use between the two poles of the earth.
（3）Conductive material has used Cu alloy material to avoid electric injury, unlimited number of can use.
（4）While technique is simplified, reliability greatly improves, and may be reused, and greatlys save cost.
The foregoing is merely specific embodiment of the utility model, but the protection of the utility model is without being limited thereto, Ren Heben
Those skilled in the art the thinkable variation being equal with the technical program technical characteristic or replacement, all cover in this reality
Within novel protection domain.
