Trigger element in the utility model trigger circuit and be between the two-plate that tinfoil paper or conductive rubber, conductive fabric make, clamp thin plastics or insulating paper and constitute.Conversion transformer B1 primary coil L2, the L3 number of turn are respectively 25～35,90～110 in the high-tension circuit, and the number of turn of secondary coil L1 is 340～360; The primary coil L4 number of turn of high-tension transformer B2 is 50～70, and the secondary coil L5 number of turn is 3650～3800.

Its principle of work is: at first cipher switch K3～K5 is allocated to duty, when the suitcase face is scratched, two-plate ac short circuit in its interlayer is LH9561 through relay J 1, power supply E1, K switch 3～K5 to audio manifold block U(model), send alarm sound.Can not rest on for a long time on the suitcase owing to scratch the steel edge or the sharp device of surface, when cutter left suitcase, relay J 1 can quit work, and alarm sound also stops simultaneously, is head it off, and the normally opened contact J1-2 of relay J 1 realizes self-locking.After pole plate was connected, electric current flow through J1, normally opened contact J1-2 adhesive, and the J1-1 normally opened contact also continues adhesive simultaneously, makes 1 pin, the 5 pin conductings of alarm sound integrated package U, and U work makes loudspeaker y send alarm sound.When in a single day anti-theft switch K1 or the K2 back contact in being installed on suitcase band or suitcase lid be disconnected (as being cut off), relay J 2 discharges, the normally closed contact J2-1 of J2 connects, and it is equivalent to the connection of pole plate, and its alarm sound integrated package U work loudspeaker stereo is reported to the police.When relay J 1 has electric current to pass through, the J1-3 normally closed contact disconnects, when electric current begins charging and makes J1-3 closed by resistance R 1, capacitor C 1, open circuit in capacitor C 1 two ends, delay circuit is connected, and after the certain hour charging, produces the collector conducting that voltage drop makes triode T1 in the rising of resistance R 2 both end voltage, make relay J 3 normally opened contact adhesives, connect high-tension circuit.High-tension circuit is to finish transformation of electrical energy by a common emitter push-pull type self-excited oscillator, and T2, T3 are two high power valve 3AD6C among the figure.After power supply is connected by J3-1, make two emitter junction forward bias by all means by R3, but because the duty of two pipes symmetry fully, so a first conducting is always arranged, as the conducting of T2 elder generation, collector current makes L2 produce self-induction electromotive force, because the positive feedback effect of coil L3, make T2 base potential step-down, the base potential of T3 raises, through repeatedly feeding back, T2 enters state of saturation, T3 enters cut-off state, and this process is very fast, only in a flash.Because the increase of T2 collector potential is very fast, on L2, produce a very big self-induction electromotive force, so on L1, respond to one 130 volts voltage, after T2 is in a single day saturated, collector current no longer increases, self-induction electromotive force on the L2 goes to zero, then the rising of T2 base potential, because the positive feedback effect of L3, collector current is reduced, at this moment be in the base stage of the T3 of cut-off state, polarity is opposite owing to connect two of same coil L3 with T2, so the base potential of T3 descends, through repeatedly feeding back, the T3 collector current is increasing, and the saturated T2 of T3 ends, and at this moment L1 goes up and produces 130 volt voltages opposite with front direction, so repeatedly, just form the voltage of approximate rectangular ripple on the L1, finished direct current and become the change action that exchanges, rectification is after capacitor C 3 filtering form direct current more stably.R5, R6 and R4 provide forward voltage to unijunction transistor T5 emitter, also are the path of power supply to capacitor C 4 chargings, and R9 and R8 provide operating voltage for respectively two base stages.When controllable silicon after triggering and conducting, capacitor C 5 causes controllable silicon to turn-off by controllable silicon T5 and coil L4 discharge, and the electric current on the L4 of coil in a flash that turn-offs changes fast especially, so at the high pressure that can produce on the coil L5 about 10,000 volts, C5 repeats said process again by current charges then, just obtains high voltage pulse like this on L5, make that skin is partly with high pressure on the suitcase, criminal has to suitcase is lost after getting an electric shock, and has played anti-sudden and violent means by force.

The cipher switch box is to make with metal or plastics, three dial positions equidistantly are placed in the box, only expose little part outside box, whether the number that is used to observe on the dial is corresponding with little trigpoint on the lid, three positions corresponding (coaxial) of three dials and base plate.When rotating driver plate makes L type conductor spring leaf turn to the position of two contact chips of fixed base plate, 2 conductings of a, b.Be exposed at the outer number of housing this moment and be the circuit turn-on number, this numerical ciphers switch can be placed on any place on the suitcase, it is Trinitarian interlock switch, have only the L type conductor spring leaf of dial 1,2,3 all with three a of relative base plate, when the b contact chip contacts, circuit stops or starting working.
