Described battery is 6V.The model ADXL500 of accelerometer 25.
Delay circuit can be arranged in upper cover plate mounting hole 19.
As its operation principle is：
Shown in Fig. 2, in the presence of launch environment, for delay circuit provides 6v voltages.
According to the circuit diagram shown in accompanying drawing 4, circuit board is processed（30mm long, 26mm wide, thick 1mm）, ADXL500 is accelerated
Degree meter is welded on corresponding position according to the delay circuit shown in Fig. 4, and there is the voltage of 3v at the two ends of accelerometer 25, while launching ring
Border is that accelerometer 25 provides acceleration, is reaching 78.4（m/s2）When, accelerometer 25 is closed, and can realize that voltage is defeated
Go out.Launch environment also provides acceleration to this low overload MEMS initiator, produces recoil.
In confined state：
Flame proof plate 7 shipped and resell on another market 4 and pin pulling out device 10 limit and can not move.As shown in Figure 1, recoil spring 3 assembling when at
In pre- tension state, recoil sliding block 2 is linked together with substrate 1.
Ship and resell on another market and 4 blocked by recoil sliding block 2 and can not rotated counterclockwise.In order to ensure recoil sliding block 2, flame proof plate 7, recoil spring
3 and flame proof spring 8 in the move in plane of substrate 1, with transparent polymethacrylates upper and lower cover board clamping, and with the spiral shell of M3
Nail is fixed together substrate 1 and upper and lower cover plate by screw hole.
In the presence of recoil, recoil sliding block 2 overcomes the pulling force of recoil spring 3 and the resistance of friction and complications glide.
Because recoil is persistently present, recoil sliding block 2 will not be returned behind the bottom of auxiliary safety groove 5 that time delay reaches substrate 1, i.e. recoil
Sliding block 2 is moved in place.Recoil sliding block 2 move release afterwards in place to ship and resell on another market 4 limitation, shipping and reselling on another market 4 is released, and ships and resell on another market 4 in recoil
In the presence of, the position shown in Fig. 8 can be rotated counterclockwise to, that is, ship and resell on another market 4 motions in place.And then, can prepare to discharge flame proof
Plate 7, releases secondary safety mechanism.
It in order to meet recoil sliding block 2 and ship and resell on another market after 4 motions is in place again pin pulling out device 10 that the delayed-action of delay circuit is
The voltage of 3v is provided.
When connecting delay circuit as shown in Figure 4, two leads are drawn in position 1 and 2 on Fig. 4, first is connected respectively and is led
The wire 16 of line 15 and second, exports the voltage of 3v.The mounting hole pulled pin on 20 insertion upper cover plates 23 of pin pulling out device 10, into limit
Position groove 9.The voltage of 3v is introduced by the first wire 15 and the second wire 16, is transferred to resistance wire 17, and resistance wire 17 can be annular
Resistance wire.
In the presence of 3v voltages, resistance wire 17 generates heat, and lights the gunpowder 18 in powder charge chamber.The gunpowder 18 lighted produces gas
Pressure, promotes push pedal 27, cuts off abaculus 24, pull pin 20, secondary safety mechanism of the releasing to flame proof plate 7.As shown in figure 3, on
Booster explosive is respectively provided with cover plate 23, flame proof plate 7 and substrate 1.So, usually due to ship and resell on another market 4 and pin pulling out device 10 to flame proof plate 7
Limitation, cause one-level booster explosive and three-level booster explosive to misplace, once one-level booster explosive accidental ignition, will not pass detonation energy
The third level is delivered to, so ensure that the safety of fuse.Hereafter, the upward sliding under the promotion of precompressed flame proof spring 8 of flame proof plate 7,
When reaching the top of main safety groove 6, dop 11 deforms with the extruding of substrate 1, into draw-in groove 12, is locked in draw-in groove 12
It is interior.Meanwhile, two grades of booster explosives on flame proof plate 7 as shown in Figure 8 reach position corresponding with one-level booster explosive, finally make one-level
Booster explosive and three-level booster explosive are turned on.Now, fuse arming, arm-to-arm as shown in Figure 8 is become by safety position.
When normal duties are processed, bullet the interference such as is most likely subject to carry, falls, vibrates and causing initiator misoperation.
Wherein, the influence fallen to recoil sliding block 2 is larger.When bullet drops into hardstand or soft ground such as steel plate, power supply can not be carried
Voltage supplied, pin pulling out device 10 can not be extracted, and flame proof plate 7 can not be moved in place, and one-level booster explosive and three-level booster explosive are to disconnect,
Initiator can not be made to be in arm-to-arm.Because collision impact is likely to produce the acceleration for moving recoil sliding block 2, but make
The recoil duration is but much smaller than with the time, recoil sliding block 2 can only move one in the presence of inertia force in this case
After segment displacement or motion in place, in the presence of the pulling force of recoil spring 3, recoil sliding block 2 can return to, and pin pulling out device 10 does not have
There is extraction, limit flame proof plate 7 and move, it is impossible to release main insurance, it is ensured that the security of initiator.
