Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described, the present invention includes but be not limited only to following embodiment.
In view of the present situation of domestic φ 2.5mm rank electric cap, the present invention mainly solves four deficiencies:
1) by design antistatic electrodes plug, antistatic problem (antistatic effect meets the requirement of " priming system test method the 14th part: ESD test " GJB5309.14-2004 or " test of priming system test method static induction density of electric spark workpiece " GJB736.11-1990) is solved in " releasing " mode;
2) exporting under the power prerequisite suitable with M100 electric cap, powder charge adopts technology of pressure mounting, and saving charge space, is 4.1mmmax by height reduction;
3) electrode plug adopts high strength glass sealed knot technology, and itself and shell adopt interference fit; Powder charge adopts technology of pressure mounting, and priming (lead azide) density is about 3.6g/cm
3, main charge (HMX or CL20 booster explosive) density is about 1.8g/cm
3, load pressure between each powder charge basically identical; Blaster cap outlet end adopts the external diameter cover plate close with shell internal diameter to close up, and reaches the tight fit design of electric cap inside.Anti-overload ability reaches 23 teeth, about 32000g;
4) output adopts titanium alloy cover plate, with titanium alloy fragmentation effect while output detonation wave, improves fan-out capability.
Therefore, the present invention designs a kind of micro electric detonator, is made up of shell 1, electric firing part 2, priming 3, main charge 4, titanium alloy cover plate 5, sealing paint 6, separated time sheet 7, fluid sealant 8 and insulating sleeve 9, and diameter is φ 2.54max, height 4.1max.Structural representation is shown in Fig. 1.Described shell is hollow cylinder, and all there is closing at both ends open place, loads electric firing part, priming and main charge successively in shell; The electrode of electric firing part stretches out the one end open of shell through separated time sheet, and separated time sheet sealed tube shell opener, as input, the other end opening of shell closed by titanium alloy cover plate, as output; The electrode of electric firing part stretches out bulb portion cover insulating sleeve, input coating fluid sealant, coating sealing paint between titanium alloy cover plate and shell.Manufacture process: electric firing part 2 electrode 201 is penetrated by separated time sheet 7 hole, then the two is loaded in shell 1 together, then filled by priming 2 in press-in shell, Powder pressing density is about 3.6g/cm
3, then main charge 4 is filled in press-in shell, Powder pressing density is about 1.8g/cm
3, then load titanium alloy cover plate 5, close up, give insulating sleeve 9 on input wire sleeve after completing and coat fluid sealant 8, coat sealing paint 6 to output.Structural representation is shown in Fig. 1.
The electric firing part 2 that the present invention relates to, is made up of electrode 201, circumpolar 202, high strength sealed knot glass 203 and bridge silk 204.Electrode 201, circumpolar 202 and high strength sealed knot glass 203 are carried out sealed knot, then carries out gold-plated process, between two electrodes then bridge silk 204 being welded on planar ends.Structural representation is shown in Fig. 2.
The electric firing part 2 that the present invention relates to self has antistatic effect; its know-why: under electrostatic spark effect; leakage path h is far smaller than the breakdown voltage of hazardous path H due to breakdown voltage, and electrostatic energy is preferentially reliably released by leakage path, thus protection hazardous path is not breakdown.Here, breakdown voltage >=4 of the breakdown voltage/leakage path h of hazardous path H, and the breakdown voltage of leakage path is far smaller than 3kV.And the key realizing above-mentioned purpose is ensured by the physical dimension of hazardous path H and leakage path h.
