Raw substantial amounts of stray electrical current, electric blasting circuit potential safety hazard is big, at present mostly using plastic detonating tube networking, subterranean tunnel explosion base
Plastic detonating tube networking is used in sheet.
At present, the conventional firing device of shock conducting tube network priming is required to special probe and electric discharge device, after each use,
Need to polish to probe, anticorrosion etc. is safeguarded, be inconvenient, and reach and must be changed after service life, it is impossible to be convenient
And persistently use.At the construction field (site), occur probe sometimes and situation not in time is lost or purchased to electric discharge device.
The U of Chinese patent literature CN 203259076 provide a kind of easy detonator percussion meter and initiation system, including
Exploder, detonator and insulated conductor；The insulated conductor is bifilar, and its one end is inserted and secured on the detonator for needing to detonate
Disconnected detonator one end in, and exposed two-conductor need to keep can electricity sparking suitable distance, the other end and exploder
Two electrodes connection.It is preferred that scheme in, insulated conductor one end, which is closed up, twists into twisted shape, and termination is cut flat, insertion need detonation
Detonator in.But in actual mechanical process, make exposed two-conductor keep the suitable distance that electric can be struck sparks to be difficult
, employed in the document and give insulated conductor one end and close up the scheme for twisting into twisted shape, but after tested, practical operation
Cheng Zhong, there is the situation that detonation fails.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of detonator percussion element, can be led stablizing percussion
On the premise of booster, without using special probe and electric discharge device, blasting cost is saved, detonation reliability is improved.
To achieve these goals, the utility model uses following technical scheme：A kind of detonator fires element, including
Two insulated conductors, described insulated conductor one end expose it is metal-cored, the bare metal core length be 1.5cm~5cm, it is described naked
Dew is metal-cored to be connected to form percussion end in the way of contact short circuit, in percussion end insertion detonator, and uses insulating tape colligation
It is fixed；
The output end of two insulated conductors and initiator is connected respectively.
It is preferred that scheme in, the short-circuit connected mode is that two bare metal cores close up and twist into helical form.
It is preferred that scheme in, the short-circuit connected mode is that two bare metal cores and at least one external diameter identical insulate
Line, which closes up, twists into helical form.
It is preferred that scheme in, the short-circuit connected mode be two bare metal cores and two external diameter identical insulated wires simultaneously
Hold together and twist into helical form, metal-cored and insulated wire interlaced arrangement.
It is preferred that scheme in, percussion end insertion detonator 4 ~ 6cm.
It is preferred that scheme in, the initiator use special detonator non-electrical firing device or electric cap and detonator double-purpose
Initiator fires initiation net.
The utility model provides a kind of detonator percussion element, can reliably fire detonator initiation net, pass through
Test is crossed, detonation success rate can reach 100%, without using special probe and electric discharge device, without industrial detonator is used, hit
Pen etc. is sent out, blasting cost is saved, it is simple to operate.

Embodiment
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
As in Fig. 1 ~ 4, a kind of detonator fires element, including two insulated conductors, and gold is exposed in described insulated conductor one end
Belong to core, the bare metal core length is 1.5cm~5cm, and the bare metal core connects to be formed in the way of contact short circuit
In percussion end, percussion end insertion detonator, and fixed with insulating tape colligation；
The output end of two insulated conductors and initiator is connected respectively.Thus structure, it is only necessary to less voltage, you can realize
Detonate successfully, the insulated conductor in this example uses the copper core of diameter 0.5 ~ 0.7, material is very easy to obtain, detonation voltage is
300 ~ 1500V, conduction time is 3 ~ 5ms.Detonation voltage of the present utility model is relatively low.
It is preferred that scheme such as Fig. 1,2 in, the short-circuit connected mode is that two bare metal cores close up and twist into helical form.
The voltage that detonated in this example is 1000V, and conduction time is 5ms.
It is preferred that scheme such as Fig. 3 in, the short-circuit connected mode be two bare metal cores it is identical with least one external diameter
Insulated wire close up and twist into helical form.Thus structure, reduces the contact area between two bare metal cores, so as to have
Effect forms point discharge, further reduction detonation voltage, and it is 800V to improve the minimum detonation voltage in security, this example, at least
Conduction time is 4ms.
It is preferred that scheme such as Fig. 4 in, the short-circuit connected mode be two bare metal cores and two external diameter identicals it is exhausted
Edge line, which closes up, twists into helical form, metal-cored and insulated wire interlaced arrangement.Thus structure, further reduces two exposed gold
Belong to the contact area between core, reduce location of short circuit, so as to be effectively formed point discharge, further reduce detonation voltage,
The electric current of circulation in insulated conductor can be especially reduced, the minimum detonation electricity in the operating temperature of insulated conductor, this example is reduced
Press as 500V, minimum conduction time is 3ms.Explanation is needed, minimum detonation voltage and minimum conduction time are the ginseng in test
Number, should increase redundancy in actual condition.
It is preferred that scheme in, percussion end insertion detonator 4 ~ 6cm.
It is preferred that scheme in, the initiator use special detonator non-electrical firing device or electric cap and detonator double-purpose
Initiator fires initiation net.
Above-described embodiment is only optimal technical scheme of the present utility model, and is not construed as limit of the present utility model
Embodiment in system, the application and the feature in embodiment can be mutually combined in the case where not conflicting.
