Description
Technical field
The utility model relates to a kind of detonator igniter head, thereby particularly relates to a kind of novel point duration and degree of heating that can strictly control bridge silk and ignition powder raising electrical detonator delay precision.
Technical background
Traditional electrical detonator igniter head bridge silk has two kinds of welding processs: the one, the bridge silk is welded direct to the detonator payment to a porter; The 2nd, earlier the bridge wire bond is received on the metal connecting piece, again metal connecting piece is welded to the detonator payment to a porter.Can igniter head reliably get angry has relation with bridge wire resistance size and ignition powder, and simultaneously, igniter head ignition consistence is relevant with the medicament homogeneity with the effective resistance of bridge silk.Because the bridge filament diameter is very little, therefore, light a fire for first two welding process for the traditional electrical detonator, all can not effectively control bridge filament length degree, just the bridge wire resistance consistence is poor, causes that igniter head is reliable gets angry required energy region and require wide; In addition, igniter head bridge silk is wrapped in the ignition powder the inside, and two kinds of electrical detonator igniter head ignition powders of tradition are stained with sticking by the bridge silk, owing to do not have retaining plate around the bridge silk, under action of gravity, ignition powder flows, thereby cause the ignition powder inequality, influence igniter head ignition energy and delay precision.
For the electric detonator of high precision, long time delay, if use the employed igniter head of traditional electrical detonator, or use for reference electrical detonator igniter head production technique, do not carry out texture improvement, there is following defective:
1. because igniter head bridge silk need wrap up ignition powder, if igniter head bridge silk directly is welded on the electric detonator electronic delay circuit board body, bridge filament length weak point can't be unified, the bridge silk is exposed outside in addition, might cause the fracture of bridge silk;
2. owing to do not have retaining plate around the bridge silk, under action of gravity, ignition powder flows, thereby causes ignition powder parcel bridge silk inhomogeneous;
3. electric detonator makes energy that igniter head gets angry from the electric capacity in the electronic delay body, is subjected to the restriction of detonator size, and capacitance is limited, if igniter head bridge wire resistance is too small, under long time delay, the energy of electric capacity can't make igniter head get angry, and causes detonator not quick-fried; If igniter head bridge wire resistance is excessive, may causes igniter head ignition required voltage to be lower than electric detonator operating on low voltage voltage, thereby influence the electric detonator safety in utilization;
Bridge wire resistance value instability, ignition powder is inhomogeneous must influence the electric detonator delay precision.
The utility model content
The purpose of this utility model provides a kind of ignition reliability height, and high conformity and the suitable novel point duration and degree of heating of producing in batches when being used for electric detonator, can effectively improve the delay precision of electric detonator, for the electric detonator energy management provides safer guarantee.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel point duration and degree of heating, comprise a printed circuit board, bridge silk and ignition powder, and its jackshaft wire bond is connected on the printed circuit board (PCB), and ignition powder drops on the printed circuit board (PCB) and wraps the bridge silk.
Described printed circuit board (PCB) comprises pad one, pad two, pad three and pad four, wherein pad one is electrically connected with pad three, pad two and pad four are electrically connected, and pad one is connected with external device respectively with pad two, and the two ends of bridge silk are welded on respectively on pad three and the pad four.
Printed circuit board (PCB) between described pad three and the pad four is provided with a groove, and the middle part of bridge silk places in the groove, and ignition powder drops in the groove and wraps the bridge silk.
Described ignition powder is covered with one deck damp-proof paint outward.
From above-mentioned constitutional features of the present utility model as can be seen, its advantage is:
1. the bridge wire bond is connected on the printed circuit board (PCB), relies on recess width between printed circuit board pads three and the pad four to determine the useful length of bridge silk, can unify igniter head bridge filament length like this and lack, make igniter head bridge silk resistance be controlled at one very among a small circle in.
2. ignition powder drops in the groove, can not flow, and not only can wrap the bridge silk fully, and can guarantee the ignition powder consumption basically identical of every igniter head.
3. igniter head change in resistance scope is little consistent with the ignition powder consumption, but guarantee point duration and degree of heating ignition reliability and consistence have improved the detonator delay precision.
4. this igniter head is simple in structure, and the bridge wire bond connects conveniently, and stationkeeping, so, can reduce because of foozle cause igniter head apart from the blasting cap initiation medicine apart from inequality.
5. by the research to bridge wire resistance and ignition powder, igniter head that the utility model provides is used in high safe electronic detonator.As everyone knows, ignition powder is responsive more, easy more realization igniting, but may make simultaneously the antistatic and stray current ability of detonator reduce, ignition powder is got over insensitiveness, and is antistatic high more with the stray current ability, but the ignition condition requirement is high more, improve electric detonator reservoir capacitance energy, restricted by factors such as detonator volume, security of system voltage.Igniter head that the utility model provides voltage of misfiring is not less than 9V, and the operating on low voltage voltage of general electric detonator, can improve electric detonator greatly and manipulate security in the process so this igniter head applies to the electric detonator portfire less than 6V.
