Description

Technical Field

[0001] This invention relates to an electronic detonator coil, specifically an electronic detonator coil without a busbar.

[0002] This invention is applicable to all industries or fields that typically require the use of at least one detonator for blasting. Typical applications include mining, quarrying, seismic exploration, and construction. Prior Technology

[0003] Detonators without a busbar, for example, consist of two functional parts: a fuse and an electronic control module.

[0004] A fuse typically consists of an explosive component and an electronic module, the latter of which can communicate with an electronic control module, for example, via cables connecting them.

[0005] When using detonators, the fuse is placed inside the explosive casing (often called the booster), which is then placed in a location that can receive it and allow the explosive to be loaded, namely the blasting wall, such as a floor or wall, or even a hole drilled in the ceiling.

[0006] The electronic control module is connected to the fuse via a cable. In use, it is placed at the exit of the blast hole to receive signals for testing or detonation, such as signals from the signal control console and / or encoder.

[0007] These signals can be exchanged wirelessly; for example, the signal control console and / or encoder can communicate with the electronic module via radio waves or light signals.

[0008] To install the fuse and electronic module, the cable connecting them can be coiled on a spool; and to unwind the coil, simply insert a tool such as a screwdriver or a simple stick through the central hole of the spool and rotate the coil around its axis to loosen it.

[0009] In addition, for busless detonators, the positioning of the electronic control module must be as precise as possible, especially as close as possible to the signal control console and / or encoder; otherwise, the communication range may be reduced, communication may not be established, or the signal may be interrupted.

[0010] Therefore, it is clear that we need to improve the installation of electronic detonators or make their operation more convenient, especially in the absence of busbars or surface connections.

[0011] However, this improvement should obviously aim to minimize the impact on the user experience. Summary of the Invention

[0012] In this context, one of the objectives of the present invention is to make up for its shortcomings as much as possible and introduce new conveniences.

[0013] Therefore, we first introduce detonator coils, whose design includes at least one cylindrical spool for winding cables, especially cables used to connect the detonator's fuse and electronic control module.

[0014] Its innovative feature is that the spool body design has at least one tube shell that serves as a holder for the fuse.

[0015] Its innovative feature is that the spool body includes at least one electronic control module housing for accommodating the electronic control chip module.

[0016] Its innovative feature is that the spool has a hollow axis, allowing the spool to rotate around its axis.

[0017] Therefore, the optimal position of the axis should be located in the center of the coil.

[0018] In one implementation example, the core portion includes a housing that can accommodate the fuse.

[0019] This arrangement allows the fuse to be placed more centrally on the coil, and when multiple detonators (including multiple coils) are stored, such as in a cardboard box, the fuses can be as far apart as possible from each other.

[0020] For example, the electronic control module housing has at least one slot extending along the axis of the spindle.

[0021] For example, in the case of an electronic control module housing, and / or as a housing for accommodating a fuse, at least one end of the online shaft is open.

[0022] A distinctive feature of this invention is that the coil design includes at least one housing containing a wedge, and the wedge is designed to form a pivotal connection with the spool.

[0023] The position of the wedge can be maintained by simple mechanical adjustments, for example, the size of the wedge can be adjusted to match the corresponding compartment by a sliding system inside the corresponding compartment cavity of the spool body or by the tube shell at one end of the wedge.

[0024] Another distinctive feature of the invention is that the coil includes a sealing plug connected to the first end of the spool body.

[0025] For example, a sealing plug has an inner surface and a corresponding outer surface.

[0026] For example, the inner surface has a fastening bayonet system that can fix the sealing plug to the first end of the coil body.

[0027] For example, the coil has a blade plug that surrounds the first end of the coil body.

[0028] For example, the sealing plug includes an electronic control module fastening system that secures the electronic control module to the sealing plug.

[0029] For example, the inner surface of the sealing plug includes a fastening system for an electronically controlled module.

[0030] For example, the sealing plug includes a first fastening system for the wedge, which is the first point at which the wedge is attached to the sealing plug.

[0031] For example, the first fastening system is used to secure the wedge to the sealing plug and is located on one side of the inner surface of the sealing plug.

[0032] For example, the sealing plug includes a second fastening system for the wedge, that is, a second point at which the wedge is fixed to the sealing plug, particularly located on one side of the outer surface of the sealing plug.

[0033] It should be noted that the second instance differs from the first.

[0034] Therefore, the sealing plug is designed to place the electronic control module on one side, i.e., the inner surface side, while fixing the wedge on the other side, i.e., the outer surface side.

[0035] When the wedge is embedded in the blast wall, the electronic control module fixed to the sealing plug can be maintained at the required height and orientation, and can be removed from the coil if necessary.

[0036] According to another example, the coil includes a blade-shaped plug, which includes a central portion, namely a circular flange, and an annular flange surrounding the central portion.

[0037] For example, the blade plug is designed as the second end of the fixed-line shaft, especially in layout configurations.

[0038] Therefore, the general structure of the coil is not significantly affected, but the redesign of the layout of each tube shell is beneficial to optimizing the detonator function.

[0039] Furthermore, we found that as the ambient temperature decreases, especially when the temperature drops below 0°C, the relatively small diameter spool makes it more difficult to loosen the cable.

[0040] Therefore, considering environmental factors and other possible design limitations, the diameter of the spool should ideally be as large as possible.

[0041] However, the thicker the spool, the greater the internal space loss.

[0042] Therefore, from all the above aspects, the present invention is valuable because it utilizes this internal space, thereby avoiding space loss.

[0043] In one particular implementation example, the coil includes a wedge.

[0044] For example, a wedge includes a portion designed to mate with a central bore to form a pivot connection, and at least one stop block to limit the wedge insertion depth.

[0045] For example, the conical portion of a wedge is designed as a stop block.

[0046] For example, a wedge-shaped stop block is designed to extend from the portion that forms a pivot connection from the axial hole.

[0047] According to another idea, the wedge includes an electrical connector.

[0048] For example, electrical connectors are designed to connect the power supply section to the functional section of a circuit.

[0049] At least the functional components included in the electronic control module.

[0050] The electrical connector of the wedge includes a metal plate, such as a laminated spring.

[0051] According to one implementation example, the wedge includes a power supply section.

[0052] For example, a coil has a layout configuration in which a wedge is inserted into its housing.

[0053] For example, the wedge is secured at the first point by the first fastening system on the sealing plug.

[0054] On the other hand, we have also introduced an electronic detonator, comprising an electronic control module, an explosive fuse, and a connecting cable connecting the fuse and the electronic control module, and the detonator also having a coil with the features described in any of the above.

[0055] Here, electronic control module refers to surface module of electronic detonator without connecting bus, such as functional module of electronic chip with integrated circuit, such as radio wave and / or optical signal communication module.

[0056] When necessary, the electronic module may have a protective cover, such as a housing, as an alternative for its mechanical support, which can fix its functional modules in the corresponding housing of the coil.

[0057] According to one implementation example, an electronic control module, particularly a functional module, includes at least some functional components of a circuit.

[0058] When the circuitry of the functional components and the power supply components are electrically connected, the electronic control module can be activated.

[0059] Here, "power supply component" refers to the part of the circuit that includes the power source, such as a battery.

[0060] For example, a functional component of a circuit includes an electrical contact surface.

[0061] For example, a power supply component includes an electrical contact surface.

[0062] For example, the electronic control module, particularly its circuitry, includes at least one connection interface, which is specifically designed to connect to the electrical connector of the wedge described later.

[0063] For example, the interface of an electronic control module includes the electrical contact surfaces of functional components within the electronic control module.

[0064] For example, the interface of an electronic control module, or more specifically, the electrical contact surface of a functional component, including a button.

[0065] In a creative option, the electronic control module, especially its functional modules, also includes power supply components for the circuitry. For example, the interface of the electronic control module also includes contact surfaces for the power supply components.

[0066] One particularly interesting implementation example is that this detonator has a specific layout configuration.

[0067] In its unique layout, the electronic control module is located in the corresponding position of the coil, that is, in the electronic control module housing of the coil.

[0068] For example, the electronic control module is completely concealed within the coil housing.

[0069] For example, the electronic control module is fixed inside the casing by a clip.

[0070] For example, the fuze is located in the corresponding housing of the coil.

[0071] For example, the connecting cable between the electronic control module and the fuse is coiled on the spool of the cable.

[0072] One creative option is to seal the first end of the shaft on the line.

[0073] A creative option is to fix the blade plug at the second end of the shaft on the line.

[0074] For example, the electronic control module is fixed to the inner surface of the sealing plug.

[0075] For example, the wedge is fixed to the inner surface of the sealing plug and secured by a first fastening system.

[0076] For example, the wedge is located inside the corresponding tube shell of the spool body.

[0077] According to another creative example, detonators have their own installation configurations.

[0078] The difference is that in this installation configuration, the wedge is located outside the corresponding housing of the coil.

[0079] The difference is that the fuse is also removed from its corresponding housing in the coil.

[0080] In the installation configuration, for example, a portion of the wedge is inserted into the hollow shaft hole of the coil, thus forming a pivotal connection between the wedge and the hollow shaft, allowing the coil body to rotate around the wedge, thereby allowing the cable to be released if needed.

[0081] In another creative example, the detonator has its own configuration for use.

[0082] In the configuration, for example, the fuse is placed at the bottom of the borehole on the blast wall and connected by a cable to an electronic control module located at the borehole exit, such as the surface of the blast wall.

[0083] The electronic control module can therefore be placed in the desired location (including orientation and height) and can be directed to the signal control console and / or encoder.

[0084] In this configuration, the electronic control module can be started by the signal control console and / or encoder.

[0085] For example, the electronic control module can be removed, or partially removed, from its housing within the spool body.

[0086] For example, at least part of the electronic control module may remain in the corresponding housing, such as in the corresponding housing of the shaft on the clamped fixing line.

[0087] If the cable is completely unplugged, the electronic control module can remain in the spindle.

[0088] For example, the electronic control module is fixed to the inner surface of the sealing plug.

[0089] In a particular application scenario, especially if the cable has been completely detached, the electronic control module connected to the inner surface of the sealing plug is further submerged into the corresponding housing of its inline spool, meaning the sealing plug remains connected to the first end of the inline spool, and the coil is secured at the outlet of the rupture by a blade plug that wraps around the first end of the inline spool. In this case, the wedge is not required.

[0090] According to one option, the wedge is fixed to the sealing plug, or to its outer surface, i.e., fixed by a second fastening system.

[0091] For example, the wedge is thus connected to the sealing plug through the wedge tip.

[0092] In this configuration, the wedge can be embedded within the blast wall to accommodate the electronic control module, particularly the electronic control chip module connected to the inner surface of the sealing plug.

[0093] Another creative option is to fix the wedge to the blade plug.

[0094] If necessary, the blade plug can be separated from the spool, such as by inserting it into the outlet of a borehole into which the fuse has been inserted.

[0095] For example, a wedge is fixed to a blade plug by its wedge post.

[0096] In one implementation example, the wedge is secured to the blade plug by its wedge post and to the outer surface of the sealing plug by its top.

[0097] When the blade plug is fixed at the exit of the borehole, the sealing plug can maintain a certain distance from the exit of the borehole.

[0098] For example, the electronic control module is also fixed to the sealing plug, particularly the inner surface of the sealing plug as described above.

[0099] Therefore, according to the present invention, a detonator incorporating a coil structure can potentially integrate a tool (here referring to a wedge) inside the coil, thereby enabling it to be used, when necessary, to release the coil and / or to establish a safe distance between the detonator and the electronic control module on the ground (or on the blast wall). This wedge also allows for better control of the electronic control module's position, including dimensions such as height and orientation, thereby facilitating better communication with the signal control console and / or the programming programmer.

[0100] In one implementation example, as described above, the wedge includes an electrical connector.

[0101] For example, electrical connectors are designed as functional components that connect power supply components and circuits, particularly for use in circuits that shut down electronic control modules.

[0102] For example, when the wedge is fixed to the sealing plug and the electronic control module is fixed to the inner surface of the sealing plug, the wedge will shut off the circuit of the electronic control module and trigger it to be powered on.

[0103] For example, particularly in the configuration in which the wedge's electrical connector is electrically connected to the interface of the electronic control module.

[0104] The power supply section and the functional parts of the electronic control module are then electrically connected.

[0105] In one implementation example, the functional module includes a functional part and a power part, and the electrical connector allows the contact surface of the functional part to be electrically connected to the contact surface of the power part.

[0106] According to another implementation example, the wedge includes a power supply component, and an electrical connector is connected to the power supply component within the wedge.

[0107] Therefore, for example, particularly in the use configuration, the wedge's electrical connector is electrically connected to the interface of the electronic control module, which includes the contact surface of the functional components.

[0108] The embodiments illustrate the present invention well, and the advantages of this invention will be described in more detail below with numerous detailed illustrations. Please refer to the accompanying drawings: Simple Explanation of the Diagram

[0120] Figure 12 shows the assembly of the blade plug, wedge, and sealing plug that secures the electronic module. Implementation

[0121] Figure 1 shows an example of the detonator coil 10 of the present invention, displayed from perspective (Figure 1A), cross-section (Figure 1B), and by definition from below (Figure 1C) and above (Figure 1D).

[0122] The coil 10 mainly includes a spool 11.

[0123] The spool 11 is a cylindrical tube with a circular outer edge in cross section, extending longitudinally between the first end 12 and the second end 13 of the cylinder.

[0124] Figure 1B better shows that there is a perforation 110 on one side of the spool body 11.

[0125] The perforation 110 is part of the fastening system 210 for hooking the sealing plug 20, as shown in Figure 2.

[0126] By definition, the first end is considered the "bottom" of the coil, while the second end is considered the "top" of the coil.

[0127] The terms "top" and "bottom" are used here for convenience of description only and have no other meaning.

[0128] The first end 12 is shown in Figure 1C from the bottom view directly below the coil.

[0129] Thus, as shown in Figures 1A and 1C, this coil has a flange blade 120 that wraps around the first end 12 of the spool body.

[0130] In particular, the flange blade 120 is designed as a shaft head to facilitate the restraint of the cable on the shaft 11 of the winding line.

[0131] In addition, the design of the flange blade 120 facilitates the placement of the coil, which can be placed on the blast wall or even at the exit of the blast hole as needed.

[0132] The second end 13 is shown from the front in Figure 1D, i.e., a top view of the coil.

[0133] As shown in Figures 1A and 1D, this coil includes a flange 130 that wraps around the second end 13 of the spool body.

[0134] Similarly, this flange 130 is clearly designed as a shaft head; forming an axial constraint relative to the cable on the coiled wire shaft 11.

[0135] Therefore, the coiled cable is fixed between the two shaft ends of the flange blade 120 and the flange 130.

[0136] Flange 130 also has a hook 131.

[0137] In particular, hook 131 is used to secure one end of the cable on the winding bobbin to prevent it from being accidentally loosened, especially in detonator layout configurations.

[0138] For example, hook 131 includes two arc-shaped baffles 132 that extend from flange 130.

[0139] The coil also includes a hollow shaft hole 14, which is formed by a tube along the central axis of the coil body.

[0140] Therefore, the hollow shaft hole 14 is configured as a pivot, and with the wedge 40 shown in FIG4 inserted therein, to form a pivotal connection for rotating the spool body, which can be used to loosen the cable.

[0141] Furthermore, the hollow shaft hole 14 can also be designed to accommodate the detonator fuse in a detonator layout configuration. The fuse is thus protected during transport.

[0142] Furthermore, the fuse can be pre-removed to allow for the insertion of a wedge, if necessary.

[0143] Figures 1C and 1D clearly show that the coil includes several reinforcing members 15.

[0144] The reinforcing member 15 here connects the central hole of the spool to the outer shell of the spool body.

[0145] The reinforcing member 15 is also divided into different compartments inside the shaft body 11, forming three tube shells 16 inside the coil.

[0146] Therefore, the cavity space formed between the shell 16 and the reinforcing member 15.

[0147] The radial compartment formed by the two reinforcing members 15, namely the shell 16a, is larger than the other two compartments. The larger shell 16a facilitates the accommodation of the electronic control module.

[0148] The other two compartments, namely the housing 16b, are the same size, and both can accommodate the wedge 40. In this case, as will be described later, which housing 16b is configured to accommodate the wedge 40 is inferred from the position of the fastening element used to secure the wedge to the sealing plug 20.

[0149] Therefore, depending on the orientation of the sealing plug 20 relative to the spool body (which includes various housings that can accommodate different components), each component enters its corresponding compartment.

[0150] Therefore, the housing 16a, which is separated radially by the outer shell of the spool body 11 and the two reinforcing members 15, is configured here to house the electronic control module 50, as shown in Figure 5.

[0151] The tube shell 16b, which is separated radially by the spool body housing 11 and two other reinforcing members 15, is designed to accommodate the wedge 40 in this layout configuration, especially for detonators.

[0152] Figure 2 is a schematic diagram of an example of the sealing plug 20 in this invention.

[0153] The sealing plug 20 includes an inner surface 21 and a corresponding outer surface 22.

[0154] As shown in Figures 2A and 2C, the sealing plug includes a fastening system 210 for securing the sealing plug to the coil, and in particular, for sealing the spool at the first end 12.

[0155] In particular, the fastening system 210 is located on the inner surface 21 of the sealing plug and mates with the perforation 110 located on the side of the spool body.

[0156] The inner surface 21 of the sealing plug also includes a fastening system 220 for securing the electronic control module 50.

[0157] It also includes a groove for inserting the electronic control module.

[0158] The sealing plug 20 also has a first fastening system 230 for the wedge. The first fastening system 230 for the wedge is located on the inner surface 21 of the sealing plug and is used to fix the wedge 40 to the sealing plug 20 at a first point on the inner side.

[0159] The first fastening system 230 of the wedge includes spaced clips for securing the wedge 40 by means of clamps, such as locking the wedge top.

[0160] Furthermore, the sealing plug 20 also has an opening 231.

[0161] The opening 231 penetrates the sealing plug 20, and is located on the inner surface 21 and is surrounded in this position by the first fastening system 230 of the wedge, in particular its several clips.

[0162] Therefore, when the wedge 40 is fixed to the sealing plug at the first point, it can be disengaged by inserting a tool or finger into the opening 231 and pushing the wedge 40 out.

[0163] The sealing plug 20 further includes a second fastening system 240 with a wedge.

[0164] The second fastening system 240 of the wedge is used to secure the wedge 40 to the sealing plug at a second location. This fastening system is located on the outer surface 22 of the sealing plug, on the same outer side of the sealing plug as the wedge, unlike the first location.

[0165] In particular, the second fastening system 240 of the wedge includes an irregularly shaped opening 24 located in the center of the sealing plug and penetrating the sealing plug.

[0166] Therefore, when the sealing plug is installed on the spool body, the irregular opening 24 is located directly opposite the hollow shaft hole 14.

[0167] The irregular opening 24 has a central circular body and two symmetrical ears of the same diameter.

[0168] As shown in Figures 2A and 2C, the second fastening system 240 of the wedge also includes a pair of blocks 242, which are located opposite each other on the central circle, and each is close to the ear cut 241 of the irregular opening 24 on its inner surface 21.

[0169] The stop block 242 is used to prevent the wedge from rotating and specifies the direction of rotation of the wedge at its second connection.

[0170] In the illustrated embodiment, the second fastening system 240 of the wedge also includes a pin 243, which is a hemispherical shape protruding from the inner surface 21 to limit the rotation of the wedge. Therefore, it helps to hold the wedge in place by means of a clamp.

[0171] Therefore, as described below, the top of the wedge 40, which is complementary to the shape of the irregular opening 24, is designed to be inserted through the irregular opening 24 and locked in the corresponding position by its own rotation.

[0172] Figure 3 is a schematic diagram of the blade plug 30.

[0173] The blade plug 30 is fixed to the second end of the coil spool.

[0174] The blade plug 30 includes a flange 31 at its center and a ring of blades 32 around it.

[0175] The flange 31 here includes a ring 33 and a cylinder 34 located at the center of the ring, and the ring 33 and the cylinder 34 are connected by a number of reinforcing members 35.

[0176] The cylinder 34 here includes a fastening system 340 for securing the wedge to the blade plug.

[0177] The fastening system 340 includes a column wall 345 that extends longitudinally through the cylinder 34. It includes a central hole 341 and a circular main cut 342 with four regularly spaced ear cuts 343.

[0178] Figure 3C shows the inner surface. The column wall 345 also includes at least one stop block 344 extending from an ear cut 343 along the edge of the main cut 342 of the column bore 341. Like the sealing plug 20, the stop block 344 is designed to prevent the wedge from rotating, and also determines the direction of the wedge's rotation, and can lock it onto the blade plug 30.

[0179] On the same surface, the pillar wall 345 also includes at least one protrusion 346. The protrusion 346 is also a hemispherical protrusion extending from the pillar wall 345 to prevent the wedge from rotating back. Therefore, it helps to hold the wedge in position by means of a clamp.

[0180] As described below, the fastening system 340 allows the wedge 40 to be inserted into and secured to the blade plug, particularly the wedge post 42 of the wedge 40.

[0181] The raised blade 32 is designed to mate with the flange 130 of the coil 10.

[0182] In particular, some blades of blade 32 are shorter than the others and form grooves throughout the impeller. These grooves are positioned opposite to the arcuate baffle 132 of flange 130.

[0183] Then, the blade is inserted and clipped onto the fixed shaft of the 30-inch line.

[0184] Figure 4 is a schematic diagram of the installation of wedge 40.

[0185] The wedge 40 here mainly includes a wedge top 41 and a wedge post 42 that extends from the top and terminates at the tip 43.

[0186] Generally speaking, the cross-section of this wedge 40 is a cross shape formed by right-angled intersections.

[0187] A preferred embodiment is that at least one of the four arms of the cross is rounded, so that at least a portion of the wedge 40 can rotate about an axis in the hollow shaft hole 14 of the coil.

[0188] The wedge apex 41 has a conical section that extends upward from the wedge post and terminates at the wedge head plate 413.

[0189] As shown in Figure 4A, the wedge plate 413 is elliptical.

[0190] Then, the conical part has, for example, two pairs of arms in centrally symmetrical positions, one pair having a greater height relative to the center of the wedge than the other pair.

[0191] It protrudes from the wedge head plate, and the wedge top includes the locking pin 410.

[0192] The locking pin 410 includes a main body 411, which is a column with a mainly circular cross-section and two fingers 412 extending from the opposite side of the circle, protruding from the surface of the wedge plate 413.

[0193] Therefore, the locking pin 410 is designed with an irregular opening 24 into which the blade plug can be inserted, and the two fingers 412 can fix the rotation of the wedge 40. The two fingers 412 slide on the inner surface 21 until they are pressed tightly against the block 242, while the wedge plate 413 is pressed tightly against the outer surface 22 of the sealing plug 20.

[0194] The locking pin 410 is also designed to be wedge-fitted into the first fastening system 230, at which point the upper surface of the body 411 is directly opposite the opening 231.

[0195] This makes it easy to move the wedge by pressing the upper surface of the body 411 through the opening 231, and to pull it out of the coil 10.

[0196] Starting from the top 41, the wedge post 42 has a main trunk 420 with a stable cross section, which is the part that mates with the hollow shaft of the spool body and allows the spool body to rotate.

[0197] The wedge post 42 also includes a circumferential groove 421 located between the main body 420 and the tip 43.

[0198] The circumferential groove 421 thus forms a double axial block because the wedge 42 is axially fixed relative to the blade plug 30 when the wedge 42 is inserted into the core hole 341 of the blade plug 30 and rotates.

[0199] In particular, the circumferential groove 421 is designed to mate with the cylindrical wall 345 of the blade plug 30.

[0200] In fact, by inserting the wedge into the core hole 341 on the wall 345 of the blade plug 30, the arm extending between the tip 43 and the circumferential groove 421 passes through the ear cut 343, and the main shaft 420 comes into contact with the wall 345. Then, by rotating the wedge, one end of the arm extending from the tip 43 engages with and slides against the inner surface of the wall 345 until they stop on the stop block 344.

[0201] The column wall 345 is wedged into the circumferential groove 421.

[0202] Therefore, we can pull out the wedge 40, thereby driving the blade plug 30 to separate it from the main body of the coil 10.

[0203] It should be noted here that the wedge 40 includes an electrical connector 414.

[0204] The electrical connector 414 has a metal plate embedded in the surface of the finger 412.

[0205] Figure 5 is a schematic diagram of the electronic control module 50.

[0206] The electronic control module 50 includes functional modules 51, such as electronic chips, including at least one radio signal communication module for communicating with a signal control center such as a console or encoder, or an optical signal communication module.

[0207] In addition, it has a protective layer 52 (optional) for protecting the functional module 51.

[0208] The protective layer 52 may be a plastic coating on the functional module 51.

[0209] Here, the protective layer 52 partially covers the functional module 51, while the portion of the functional module 51 outside the protective layer 52, particularly the lower plate 53, can be inserted into the fastening system 220 of the sealing plug 20, particularly into its groove, to fix the electronic module in the corresponding position of the sealing plug 20.

[0210] Here, the electronic control module 50, and especially its functional module 51, includes circuit functional components and power supply components.

[0211] Power supply components include, for example, battery 54.

[0212] As shown in Figure 5C, in this example, the circuit functional component includes an electrical contact surface 55, while the power supply component includes an electrical contact surface 56.

[0213] The electrical contact surfaces 55 and 56 here constitute the connection interface 57 of the electronic control module.

[0214] Interface 57 is therefore used to connect to the electrical connector 414 of the wedge, thereby enabling the power supply component to form an electrical connection with the functional components of the functional module when the detonator is used in the configuration.

[0215] Here, a portion of the protective layer 52 covers the interface, with the protruding portion 58 covering the interface 57.

[0216] When the interface 57 contacts the electrical connector 414 of the wedge, the protrusion 58 helps to achieve insulation protection (as shown in Figure 4).

[0217] Figures 6 to 11 are assembly suggestions of the components of a detonator manufactured according to the present invention, as shown in Figures 1 to 5.

[0218] Therefore, as shown in Figure 6A, a perspective view of the coil 10 is presented, in which the electronic module 50 and the wedge 40 are placed and secured by the sealing plug 20.

[0219] Except for the fuze, which is not shown in the diagram, and the cable connecting the fuze and module 50, the coil configuration conforms to the layout configuration of the detonator.

[0220] In Figure 6A, the blade plug 30 seals the second end of the spool body, while in Figure 6B, it is separate from the spool body.

[0221] Figure 7 illustrates the layout of the wedge 40 and the electronic module 50 fixed to the sealing plug 20, especially its inner surface 21, as shown in Figure 6 when they are concealed inside the spool body.

[0222] As described above, to remove the wedge, one can push its top through the opening 231 of the sealing plug, or pull it out directly with the wedge post 42.

[0223] The electronic control module 50 is also at least partially fixed in the shaft body of the line by a sealing plug.

[0224] However, the sealing ring is not essential and can be replaced by a simple sliding system in the main compartment of the spool body, which can be adjusted to fix the electronic module.

[0225] Figure 8 shows the position of the wedge, for example, in the installation configuration of the detonator, indicating how to rotate the spool.

[0226] Therefore, when the wedge post 42 of the wedge is inserted into the irregular opening 24, the conical part of the wedge tip 41 abuts against the central part of the irregular opening 24 and stops.

[0227] In this way, coil 10 can be rotated around wedge 40.

[0228] Figure 9 illustrates the fixation of the wedge 40 at its second location and shows how the electronic module can be disassembled from the spool body.

[0229] When the locking pin 410 of the wedge is inserted, its finger 412 should be aligned with the ear cut 241 of the irregular opening 24 (Fig. 9A).

[0230] Then, the locking pin 410 can be pushed into the irregular opening 24 until the wedge plate 413 contacts the outer surface 22 of the sealing plug (Fig. 9B).

[0231] Next, twist the wedge. Finger 412 slides on the inner surface 21 until it contacts the stop block 242 (Fig. 9C).

[0232] The wedge is thus locked in place.

[0233] By pulling the wedge, the fastening system 210 of the sealing plug is released from the spool 11 of the coil 10, so that the sealing plug 20 can at least partially detach the electronic control module 50 from the spool 11 (Fig. 9D).

[0234] Meanwhile, as shown in Figure 10, the electrical connector 414 of the wedge contacts the interface 57. In this configuration, similar to that of a detonator, the electrical connector 414 electrically connects the electrical contact surface 55 of the circuit functional component and the electrical contact surface 56 of the power supply component in the functional module 51. The electronic control module 50 is thus activated.

[0235] Therefore, the main function of the sealing plug 20 is to maintain the position of the electronic module and connect it to the wedge 40.

[0236] The wedge 40 is locked onto the sealing plug 20 supporting the electronic module 50, which also keeps it at a distance from the blast wall.

[0237] This function can also be achieved through a simple sliding system (located on the wedge and sealing plug) without the need for locking.

[0238] If the cable has been completely detached from the spool, it is not necessary to pull the electronic module out of the spool; otherwise (as in the Faraday cage effect), the wedge attached to the sealing plug can remove the electronic module from the spool, as described above.

[0239] Furthermore, the shape of the wedge facilitates the embedding of the wedge, electronic module, and sealing plug element (including or excluding the spool) into the blast wall (e.g., in a pile of fine stones, drilling residue, etc.).

[0240] In addition, or as shown in Figure 11, the wedge 40 can be fixed to the blade plug 30.

[0241] For this purpose, the wedge post 42 of the wedge can be inserted into the core hole 341 of the blade plug wall 345 (Fig. 11A) until a portion of the wedge post 42 abuts against the wall 345 (Fig. 11B).

[0242] Then, the wedge is twisted (Fig. 11C), and the column wall 345 is locked in the circumferential groove 421.

[0243] It is still possible to detach the blade plug 30 from the spool body by pulling the wedge 40 (Fig. 11D).

[0244] Finally, Figure 12 illustrates the layout combination shown in Figures 10 and 11.

[0245] The wedge 40 is connected to both the sealing plug 20 supporting the electronic module 50 and the blade plug 30.

[0246] For example, the blade plug 30 can be conveniently fixed at the exit of the borehole, such as a borehole where a fuse has been placed deep inside.

[0247] Furthermore, this configuration ensures the predetermined height between the electronic module 50 and the blasting wall. In fact, the blade plug 30 prevents the wedge 40 from being buried too deep in the blasting wall, or even submerged at the bottom of the borehole.

[0248] Figure 12 is a schematic diagram of the configuration without the coil; however, the sealing plug 20 can still remain on the spool as the cable is loosened.

[0249] For underground blasting applications (such as horizontal drilling in tunnels or vertical drilling in arches), the shape of the blade plug 30, which is the same as the flange blade 120 of the spool, has design advantages.

[0250] Based on the first example, if the cable is completely detached, the spool containing the electronic module can be placed at the entrance of the borehole using either the blade plug 30 or the flange blade 120. The specific choice depends on the dimensions of the borehole, the blade plug 30, and / or the flange blade 120.

[0251] According to the second example, if some of the remaining coiled cable is left on the spool, it is best to first lock the wedge onto the blade plug 30, and then lock the new component onto the sealing plug 20 supporting the electronic module (as shown in Figure 12), so that the final assembled component can be placed at the borehole (whether the electronic module 50 is removed from the spool body 11 is not necessary, depending on the remaining cable on the coiled spool).

[0252] Since the flange blades 120 and blade plugs 30 of the spool body have different diameters, either one can be used for embedding, adapting to boreholes of different diameters. The blades of the blade plug 30 or the flange blades 120 have relative structural flexibility, further enhancing the adaptability of the blade plug 30 or the flange blades 120 to boreholes drilled under different conditions.

[0253] The above regulations on the design of the various functions integrated into the spool can limit modifications to the detonator coil.

[0254] All of these features are also compatible with the fuse inserted into the spool, and provide secure protection for the fuse, especially during transport.

[0255] This design also avoids the need for external tools to loosen the coil or install the detonator, as the wedge, which serves as a tool for loosening the cable, has been integrated into the coil.
