Abstract
The utility model relates to a novel electronic igniter for an electronic detonator. The novel electronic igniter structurally comprises an electronic detonator chip, a bus interface and an ignition device, wherein the electronic detonator chip and the ignition device are respectively arranged on a small main plate body; a first bonding pad and a second bonding pad which are used for welding the bus interface are arranged at one end of the small main plate body; a first powder head and a second powder head are arranged at the other end of the small main plate body; two ends of the bridge wire of the ignition device are respectively welded on the first powder head and the second powder head. According to the novel electronic igniter, integrated connection between the electronic detonator chip and the ignition device is realized through the small main plate body, so that the whole structure of the electronic detonator is firm, thereby avoiding the risk of falling off and improving the safety and stability of the electronic detonator product; the bridge wire of the ignition device is electrically mounted on the small main plate body, and thus the working efficiency of assembling the ignition device and the initiation rate of the electronic detonator are both improved.
Description
Technical field
The utility model relates to a kind of electric detonator, specifically a kind of novel electron detonator electronic ignition tool.
Background technology
The research of electric detonator starts from early 1980s, is the development trend of delay detonator technology.Electric detonator is technique and the designing technique based on integrated circuit, with electronic chip, replaces the time delay gunpowder in common electric cap, realizes a kind of Novel detonator of accurate timing, security control.Electric detonator is that electric detonator chip, energy-storage travelling wave tube, interface device and igniter etc. are all incorporated on a platelet, reaches the function that realizes accurate delay, safe initiation.But electric detonator also has the problem that production efficiency is not high at present, and the link of igniter jackshaft silk is easily out of shape, and causes bridge silk resistance to change, thereby has the risk that igniter cannot normally be got angry.
Utility model content
The purpose of this utility model is just to provide a kind of novel electron detonator electronic ignition tool, to improve the production efficiency of electric detonator product, improves stability and the security of electric detonator.
The utility model is achieved in that a kind of novel electron detonator electronic ignition tool, comprise electric detonator chip, EBI and igniter, described electric detonator chip and described igniter are separately positioned in platelet main body, in one end of described platelet main body, be provided with for welding the first pad and second pad of described EBI, the other end in described platelet main body is provided with the first medicine head and the second medicine head, and the two ends of the bridge silk in described igniter are welded on respectively on described the first medicine head and described the second medicine head.
In described platelet main body, be provided with one section of edge section of inside contracting, described igniter is arranged in the described edge section of inside contracting.
The both sides of the described edge section of inside contracting are hyperbola or splayed.
In the described edge section of inside contracting, by shell, be connected with the ignition portion of nonpriming material detonator.
Platelet main body employing rigid structure due to electric detonator, the spacing of the first medicine head and the second medicine head does not change when being subject to External Force Acting, thereby the resistance of bridge silk can be controlled in an accurate scope, guaranteed the uniformity of bridge silk resistance, evaded because bridge silk resistance is excessive or the too small risk that causes that medicine head is misfired.Complete after bridge silk Denso, can partly coat ignition powder in the igniter of platelet main body.The platelet main body of electric detonator adopts integrated structure, has saved the step of assembling igniter and platelet main body, has reduced production process one, has improved the production efficiency of electric detonator product.
Nonpriming material detonator is the trend of following detonator development.Due to the particularity of nonpriming material detonator sparking gear, traditional platelet and nonpriming material detonator are incompatible.The utility model arranges one section of edge section of inside contracting in platelet main body, when assembling, the igniter of nonpriming material detonator is stuck in this edge section of inside contracting, igniter can be fitted together with platelet main body more securely, increase the stability of detonator integral body, realized the compatibility of nonpriming material detonator.
The utility model has been realized integrated connection the between electric detonator chip and igniter by platelet main body, electric detonator chip is connected respectively by two pads in platelet main body with EBI, make thus the overall structure of electric detonator firmer, avoid original igniter to hold caducous risk, improved security and the stability of electric detonator product; On the first medicine head and the second medicine head by the bridge silk Denso in igniter in platelet main body, improved the operating efficiency of assembling igniter, the link of having avoided traditional igniter jackshaft silk is easily out of shape, causes bridge silk resistance to change and risk that igniter cannot normally be got angry, has improved the percentage of initiation of electric detonator.
The utility model has increased the scope of application of electric detonator platelet, has strengthened the versatility of platelet.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the structural representations of two kinds of specific implementations of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the parts such as electric detonator chip 3, EBI (not shown), igniter 5 and platelet main body 2.Electric detonator chip 3 and igniter 5 are separately positioned in platelet main body 2, make electric detonator chip 3 and igniter 5 can adopt integrated connected mode to be connected.In one end of platelet main body 2, be provided with the first pad 1 and the second pad 4, EBI is welded on the first pad 1 and the second pad 4, and is electrically connected to electric detonator chip 3 by the first pad 1 and the second pad 4.The other end in platelet main body 2 is provided with the first medicine head 7 and the second medicine head 9, and the two ends of the bridge silk 8 in igniter 5 are welded on respectively on the first medicine head 7 and the second medicine head 9.In platelet main body 2, be provided with one section of edge section of inside contracting 6, the both sides of this edge section of inside contracting are hyperbola (Fig. 1) or splayed (Fig. 2), and igniter 5 is arranged in this edge section of inside contracting 6.In this edge section of inside contracting 6, can pass through the ignition portion of the shell clamping nonpriming material detonator of detonator.
Operation principle of the present utility model is: electric detonator chip 3 is controlled energy storage devices by 8 electric discharges of bridge silk, by electric energy conversion, is heat energy, makes to get angry medicament detonation and then detonating primer.
