Abstract
The utility model discloses a kind of detonating primer, including primer casing, primer casing top is provided with the fixing plug of exploding wire, and exploding wire is fixing is provided with two exploding wires beyond the Great Wall, and exploding wire lower end connects protected piece, and protection block is arranged in primer casing；Described protection block is outside equipped with thermal protection band, and thermal protection band lower end arranges electric match, and two electrodes of electric match and exploding wire are telescopic joint by protection；Described electric match bottom is provided with ignition charge, and ignition charge bottom is provided with time delay lead-in wire, and time delay lead-in wire bottom connects has powder charge chamber, powder charge chamber to be arranged at bottom primer casing.The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.
Description
Technical field
This utility model relates to a kind of detonating primer, belongs to mechanical component field.
Background technology
Blasting network initiation ends generally uses electric cap or Nonel detonator to detonate, use Nonel detonator as initiation ends,
Especially high intensity high precision fuse blasting cap, can cause explosive use cost to increase, and operation extremely inconvenience；Use
Electric cap is as initiation ends, but the convenient interference being easily subject to electrostatic, radio frequency electrical and stray electrical current of operation, and easily draw
Send out early quick-fried accident, there is bigger potential safety hazard.
Utility model content
The deficiency existed for prior art, technical problem to be solved in the utility model is to provide a kind of detonating primer,
Rational in infrastructure, use safety.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of detonating primer, including primer casing,
Primer casing top is provided with the fixing plug of exploding wire, and exploding wire is fixing is provided with two exploding wires beyond the Great Wall, and exploding wire lower end connects
Protected piece, protection block is arranged in primer casing；Described protection block is outside equipped with thermal protection band, thermal protection band lower end
Arranging electric match, two electrodes of electric match and exploding wire are telescopic joint by protection；Described electric match bottom is arranged
Having ignition charge, ignition charge bottom to be provided with time delay lead-in wire, time delay lead-in wire bottom connects has powder charge chamber, powder charge chamber to be arranged at detonator
Outer casing bottom；Described powder charge chamber is taper, and its tapering is 1: 15, a diameter of powder charge chamber bottom primer casing, the powder charge chamber
The diameter of maximum；Described one end igniting lead-in wire connects magnet ring I, and being provided with magnet ring II, magnet ring I in protection block is aluminum nickel
Cobalt magnet, magnet ring II is ferrite magnet.
Optimizing, above-mentioned detonating primer, described time delay lead-in wire is outside is provided with anti-overheated insulating wool, and anti-overheated insulating wool is folder
The miscellaneous asbestos cloth having fire prevention clay.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Twice electric energy conversion,
The electric energy the most simultaneously meeting two magnet ring frequency bands just can be transferred to medicine head detonating capsule, and the frequency band that therefore can realize detonating is the narrowest,
Improve Magnedat anti-electricity security feature further, eliminate the hazardness that common power detonates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1 be primer casing, 2 be the fixing plug of exploding wire, 3 be exploding wire, 4 be protection block, 5 be thermal protection band,
6 be electric match, 7 be time delay lead-in wire, 8 be powder charge chamber, 9 be magnet ring I, 10 for magnet ring II.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of detonating primer, and including primer casing, primer casing top is provided with the fixing plug of exploding wire, draws
Quick-fried line is fixing is provided with two exploding wires beyond the Great Wall, and exploding wire lower end connects protected piece, and protection block is arranged in primer casing；
Described protection block is outside equipped with thermal protection band, and thermal protection band lower end arranges electric match, two electrodes of electric match with
Exploding wire is telescopic joint by protection；Described electric match bottom is provided with ignition charge, and ignition charge bottom is provided with time delay lead-in wire,
Time delay lead-in wire bottom connects has powder charge chamber, powder charge chamber to be arranged at bottom primer casing；Described powder charge chamber is taper, and its tapering is 1:
15, the diameter of the powder charge chamber a diameter of powder charge chamber maximum bottom primer casing；Described one end igniting lead-in wire connects magnetic
Ring I, being provided with magnet ring II, magnet ring I in protection block is alnico magnet, and magnet ring II is ferrite magnet.Described time delay is drawn
Being provided with anti-overheated insulating wool outside line, anti-overheated insulating wool is the asbestos cloth being mingled with fire prevention clay.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.Twice electric energy conversion,
The electric energy the most simultaneously meeting two magnet ring frequency bands just can be transferred to medicine head detonating capsule, and the frequency band that therefore can realize detonating is the narrowest,
Improve Magnedat anti-electricity security feature further, eliminate the hazardness that common power detonates.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in essential scope of the present utility model, the change made, retrofits, adds or replaces,
All should belong to protection domain of the present utility model.
