Description

Technical Field

[0001] The invention belongs to the technical field of blasting tools, and in particular relates to an assembling method of an electronic detonator. Background Art

[0002] Detonators are the main explosive materials in blasting projects. Their function is to generate detonation energy to detonate various explosives, detonating cords, and booster tubes. Detonators are divided into two types: ordinary detonators and digital electronic detonators.

[0003] Traditional electronic detonators basically have a reinforcing cap and an ignition head. The working principle is to connect to the detonator through a wire, receive the detonation information, and the capacitor provides energy to ignite the ignition head through the electronic control module. The ignition head then ignites the primer, which then drives the positive detonator to ignite the detonator, and finally drives the explosive wrapped in the detonator to explode.

[0004] For example, publication number CN117589018A discloses a high temperature resistant electronic detonator with a vacuum insulation layer, comprising a tube shell, the tube shell comprising an insulation outer shell and an insulation inner shell arranged inside the insulation outer shell, a vacuum insulation layer is provided between the insulation outer shell and the insulation inner shell, the inner bottom of the tube shell is provided with a primary charge of high temperature resistant explosive, a secondary charge of high temperature resistant explosive and a high temperature resistant detonator in sequence from bottom to top, a reinforcing cap is provided on the upper side of the high temperature resistant detonator, a high temperature resistant rubber plug is clamped on the upper part of the tube shell, and a PCB circuit board installed inside the tube shell is provided below the high temperature resistant rubber plug. An electronic control module is installed on the PCB circuit board, a high temperature resistant electric ignition head is provided at the lower end of the PCB circuit board, a soldering point is provided at the upper end of the PCB circuit board, a high temperature resistant foot line is provided in the middle of the high temperature resistant rubber plug, a buckle is connected to the upper end of the high temperature resistant foot line, and the lower end of the high temperature resistant foot line is welded to the soldering point through a wire, and a tube shell bayonet is installed at the upper end of the tube shell.

[0005] The technical solution disclosed in the above patent document is an integrated structure of high-temperature resistant leg wire detonators. The integrated structure is to directly weld the high-temperature resistant leg wire to the detonator during the production and assembly process. Therefore, during packaging and transportation, the wires and detonators need to be packaged and transported together. Since detonators are special controlled products, they require specific packaging and specific transportation equipment, which increases the cost of packaging and transportation. In addition, the workshops and equipment for the production of electronic detonators are also specific workshops and equipment that need to meet safety requirements, and the production and assembly of detonating wires and detonators in the same workshop will increase the production input cost. Summary of the invention

[0006] The object of the present invention is to provide an assembly method of an electronic detonator, aiming to solve the problem of high production and transportation costs of electronic detonators in the prior art.

[0007] To achieve the above-mentioned purpose, an embodiment of the present invention provides an assembly method of an electronic detonator, wherein the electronic detonator includes a basic detonator, an electronic control module and a detonating wire, the basic detonator is filled with explosive medicine, the electronic control module extends into the basic detonator and seals the mouth of the basic detonator to form an electronic detonator detonating body; the electronic control module is provided with a first connecting piece, and the detonating wire is provided with a second connecting piece; the electronic detonator detonating body and the detonating wire are independent of each other, and during the production process, the electronic detonator detonating body and the detonating wire are produced in different workshops, and the electronic detonator detonating body is assembled and produced in a riot-proof workshop; the electronic detonator detonating body and the detonating wire are separately packaged and transported; at the detonation site, the second connecting piece of the detonating wire is connected to the first connecting piece of the electronic detonator detonating body; the electronic detonator detonating body can be connected to detonating wires of different lengths.

[0008] Furthermore, the first connecting member is a socket provided at the end of the electronic control module, and the second connecting member is a plug.

[0009] Furthermore, both sides of the socket are provided with card connectors protruding inwards, and the plug is provided with a card slot and a rubber ring.

[0010] Furthermore, the basic detonator includes a detonating tube and a protective shell, the electronic control module has a detonating end and a connecting end, the detonating end extends into the detonating tube, and the connecting end extends out of the detonating tube; the protective shell is tightly sleeved on the connecting end, and one end of the protective shell is sleeved on the end of the detonating tube, and the first connecting piece is arranged at the other end of the protective shell.

[0011] Furthermore, the protective shell includes a first section, a second section and a transition section, which connects the first section and the second section; the cross section of the first section is smaller than the cross section of the second section, the first section is sleeved on the detonator tube, and the connecting end extends into the second section.

[0012] The above one or more technical solutions in the assembly method of the electronic detonator provided by the embodiment of the present invention have at least one of the following technical effects:

[0013] 1. The basic detonator and the electronic control module are assembled to form the electronic detonator detonating body, which is independent of the detonating wire. At the detonation site, the second connecting piece of the detonating wire can be connected to the first connecting piece of the electronic detonator detonating body, which is simple and convenient to operate.

[0014] 2. The detonating cord and the electronic detonator detonating body are independent of each other and are assembled and connected only when needed. Therefore, the electronic detonator detonating body and the detonating cord can be packaged and transported separately. Therefore, under the same volume, more electronic detonator detonating bodies can be packaged and transported, while the detonating cord can be packaged and transported in conventional packaging, so the packaging and transportation costs are low.

[0015] 3. Detonating wire is a conventional product and does not need to occupy the production workshop of detonators; and it can be produced nearby, which can reduce production and transportation costs.

[0016] 4. Since the detonating wire is independent, it can be equipped with detonating wires of different lengths. When actually used, the corresponding length of wire can be used. Compared with the traditional reserve electronic detonator that detonates the main body and connects the detonating wires of different lengths, the electronic detonator has lower cost and wider application.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0024] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, an assembly method of an electronic detonator is provided, wherein the electronic detonator includes a basic detonator 110, an electronic control module 120 and a detonating wire 200. The basic detonator 110 is filled with detonating medicine, and the electronic control module 120 extends into the basic detonator 110 and seals the mouth of the basic detonator 110 to form an electronic detonator detonating body 100. The electronic control module 120 is provided with a first connecting member 121, and the detonating wire 200 is provided with a second connecting member 210, and the second connecting member 210 is used to be plugged with the first connecting member 121. At the detonation site, the detonating wire 200 is connected to the electronic detonator detonating body 100 by docking the second connecting member 210 with the first connecting member 121. Specifically, the electronic detonator detonating body 100 and the detonating wire 200 are packaged and transported independently; when detonating the electronic detonator detonating body 100, a detonating wire 200 is taken, and the second connecting piece 210 of the detonating wire 200 is plugged into the first connecting piece 121, so that the detonating wire 200 and the electronic detonator detonating body 100 are assembled into one, and the other end of the detonating wire 200 is connected to the detonation control power supply. The operation is simple and convenient. The detonating wire 200 and the electronic detonator detonating body 100 are independent of each other, and the two are assembled and connected only when needed. Therefore, the electronic detonator detonating body 100 and the detonating wire 200 can be packaged and transported separately, so that more electronic detonator detonating bodies 100 can be packaged and transported under the same volume, and the detonating wire 200 can be packaged and transported in conventional packaging, so the packaging and transportation costs are low. In addition, the detonating wire 200 is a conventional product and does not need to occupy the production workshop of the detonator; and it can be produced nearby, which can reduce the production and transportation costs. Furthermore, since the detonating wire 200 is independent, detonating wires of different lengths can be provided, and when actually used, wires of corresponding lengths can be used. Compared with the traditional reserve electronic detonator, the electronic detonator that detonates the main body and connects detonating wires of different lengths has lower cost and wider application.

[0025] Furthermore, the first connecting member 121 is a socket provided at the end of the electronic control module 120, and the second connecting member 210 is a plug. The plug and the socket are connected to realize the assembly of the detonating wire 200 and the electronic detonator detonating body 100. The operation is simple, and the connection is stable after assembly.

[0026] Furthermore, the two sides of the socket are provided with a clamping piece 122 protruding inward, and the plug is provided with a clamping groove 211 and a rubber ring 212. When the plug is inserted into the socket, the clamping piece 122 is clamped into the clamping groove 211, and the rubber ring 212 is tightly fitted in the socket to prevent the detonating line 200 from loosening and falling off, thereby ensuring the stability of the connection.

[0027] Furthermore, the basic detonator 110 includes a detonating tube 111 and a protective shell 112, and the electronic control module 120 has a detonating end and a connecting end, the detonating end extends into the detonating tube 111, and the connecting end extends out of the detonating tube 111. The protective shell 112 is tightly sleeved on the connecting end, and one end of the protective shell 112 is sleeved on the end of the detonating tube, and the first connecting member 121 is provided at the other end of the protective shell 112. This embodiment can shorten the length of the detonating tube 111, reduce the processing difficulty of the detonating tube 111, and also reduce its processing cost. In addition, by providing the protective shell 112, and one end of the protective shell 112 is sleeved on one end of the detonating tube 111. Therefore, the electronic control module 120 can be better protected by the protective shell 112.

[0028] Furthermore, the protective shell 112 includes a first section 101, a second section 102 and a transition connecting section 103. The two ends of the transition connecting section 103 are respectively connected to the first section 101 and the second section 102. Moreover, the cross section of the first section 101 is smaller than the cross section of the second section 102, and the first section 101 is sleeved on the detonating tube 111, and the connecting end extends into the second section 102. In this embodiment, the first section 101 is sleeved on the mouth of the detonating tube 111, so that the strength of the mouth of the detonating tube 111 can be increased to avoid deformation due to force and squeezing to the electronic control module 120. In addition, the external dimensions of the connecting end can be further increased. Specifically, the amount of rubber coating can be increased at this position, thereby increasing its strength.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
