Abstract
Description
Technical Field
[0001] This utility model relates to the field of pyrotechnics technology, and in particular to an ignition assembly for an electronic detonator, an electronic detonator control module containing the assembly, and an electronic detonator. Background Technology
[0002] Currently, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, rock and ore separation, open-pit mine blasting, and other applications. Existing electronic detonators mainly include lead wires, control modules, ignition bridge wires with ignition charge, base charge, and detonator housings. In addition, during the production of electronic detonators, the control module needs to be assembled into the detonator housing, which protects the control module.
[0003] Furthermore, in the electronic detonator industry, the outer diameter of electronic detonators is generally 7.0mm-7.2mm. The detonator housing used to assemble the control module has certain specifications and size limitations. The width accuracy of the control module directly affects the smoothness and reliability of assembling the control module into the detonator housing. Moreover, when the width of the control module is greater than the inner diameter of the detonator housing, it is difficult to assemble the control module into the detonator housing.
[0004] Furthermore, the main ignition transducer used in existing electronic detonators to achieve ignition is the ignition bridge wire assembly, such as... Figure 1 As shown, the ignition bridge wire assembly mainly includes a pair of parallel metal connecting bridges 7 and an ignition bridge wire 8 connected between the pair of metal connecting bridges 7. The middle part of the ignition bridge wire 8 is suspended. The pair of metal connecting bridges 7 are connected to one end of a circuit board with a control circuit. The ignition bridge wire 8 is controlled by the control circuit to achieve ignition. However, due to the size requirements of the control module, the size of the metal connecting bridges 7 is relatively small. Furthermore, due to the limitations of the structure and processing technology of the metal connecting bridges 7, the metal connecting bridges 7 have poor rigidity. During the production process, such as the dipping process in the production of electronic detonators, they are easily subjected to external forces and may bend or deform, which can easily lead to damage to the ignition bridge wire 8. In addition, during the detonation of the electronic detonator, the ignition bridge wire 8 is easily affected by the blasting vibration produced by the detonation of the preceding electronic detonator. The ignition bridge wire 8 is easily broken by impact, which can lead to mis-detonation of the electronic detonator and pose a significant safety risk.
[0005] Furthermore, another ignition transducer primarily used in existing electronic detonators is the ignition bridge diaphragm. This ignition bridge diaphragm is typically bonded to one end of a circuit board containing control circuitry using a heating film bonding process. Ignition of the ignition bridge diaphragm is controlled by the control circuitry, and the ignition bridge diaphragm possesses good rigidity. However, since the heating film is bonded to only one side of the circuit board, there is a problem of one-sided ignition during heating film ignition, which can easily lead to partial explosion of the detonator tip, resulting in insufficient ignition power and the detonator tip failing to ignite the electronic detonator, thus causing misfires. Therefore, there is an urgent need for an ignition component that can effectively prevent misfires in electronic detonators. Summary of the Invention
[0006] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide an ignition component for an electronic detonator that helps to avoid misfires; in addition, it also provides an electronic detonator control module and an electronic detonator.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: According to one aspect of this application, an ignition assembly for an electronic detonator is provided, comprising: The support body has a plate-like structure, a first conductive connection part is provided on a first surface in the thickness direction of the support body, and a second conductive connection part is provided on a second surface in the thickness direction of the support body. An ignition bridge wire is provided, wherein the first end of the ignition bridge wire is electrically connected to the first conductive connection portion, the ignition bridge wire is wound from the first surface of the support body in the thickness direction to the second surface of the support body in the thickness direction, and the second end of the ignition bridge wire is electrically connected to the second conductive connection portion.
[0008] The beneficial effects of this utility model are as follows: In this embodiment, the ignition bridge wire winds from the first surface of the support body to the second surface of the support body in the thickness direction. The first end of the ignition bridge wire is electrically connected to the first conductive connection part, and the second end is electrically connected to the second conductive connection part. This facilitates support for the ignition bridge wire through the support body, reducing the length of the ignition bridge wire suspended or even preventing it from being suspended. By placing the ignition assembly inside the electronic detonator, when the ignition assembly in this embodiment is subjected to blasting vibrations from the previously blasted electronic detonator during the blasting process, the support body provides support for the ignition bridge wire and improves its vibration and damage resistance, preventing the ignition bridge wire from being broken by impact, thereby preventing the electronic detonator from mis-blasting due to the breakage of the ignition bridge wire; further... Furthermore, in this embodiment, the support body has a plate-like structure. During the production process, such as the dipping process in the production of electronic detonators, the support body is not easily bent or deformed by external forces. It also facilitates the support of the ignition bridge wire, which helps to improve the rigidity of the ignition bridge wire and thus helps to prevent damage to the ignition bridge wire. In addition, a portion of the length of the ignition bridge wire is provided on the first side in the thickness direction of the support body, and a portion of the length of the ignition bridge wire is also provided on the second side in the thickness direction of the support body. This means that the length of the ignition bridge wire is provided on both sides in the thickness direction of the support body. This is beneficial for setting the ignition assembly in this embodiment inside the electronic detonator and achieving double-sided ignition through the ignition bridge wire. It avoids the problem of partial explosion of the charge head caused by single-sided ignition and provides sufficient ignition power to detonate the electronic detonator through double-sided ignition, thereby preventing the electronic detonator from mis-exploding.
[0009] In addition, based on the above technical solution, this application can be further improved as follows, and can also have the following additional technical features.
[0010] According to one embodiment of this application, the first conductive connection portion and the second conductive connection portion are arranged back to back in the thickness direction of the support body, and the ignition bridge wire has a U-shaped structure.
[0011] In this embodiment, the ignition bridge wire has a U-shaped structure. The structure of the ignition bridge wire is simple and easy to produce. Furthermore, the first conductive connection part and the second conductive connection part are arranged back to back in the thickness direction of the support body. This is beneficial for connecting the first end of the ignition bridge wire to the first conductive connection part and the second end of the ignition bridge wire to the second conductive connection part. It also makes it easier for the U-shaped ignition bridge wire to be set close to the support body, so that the support body can provide support for the ignition bridge wire.
[0012] According to one embodiment of this application, an agent-adhesive section for adhering ignition agent is formed between the first end and the second end of the ignition bridge wire.
[0013] In this embodiment, a propellant dipping and adhesion section is formed between the first and second ends of the ignition bridge wire for adhering the ignition agent. In the dipping process of producing electronic detonators, this facilitates the contact and adhesion of the ignition agent with the propellant dipping and adhesion section.
[0014] According to one embodiment of this application, the drug-adhesive segment includes: The first medicine-dipped adhesive segment has a first end that is electrically connected to the first conductive connection portion, and a second end that extends away from the first conductive connection portion to form an extension portion one. The second drug-adhesive section has a first end that is electrically connected to the second conductive connection portion, and a second end that extends away from the second conductive connection portion to form an extension portion two. The third drug-adhesive section is connected between the first extension and the second extension, and the third drug-adhesive section bypasses the support body in the thickness direction of the support body.
[0015] In this embodiment, the first end of the first agent-dipped adhesive section is electrically connected to the first conductive connection portion, and the first end of the second agent-dipped adhesive section is electrically connected to the second conductive connection portion. This improves the reliability of the connection between the first and second agent-dipped adhesive sections. Furthermore, the third agent-dipped adhesive section is connected between the first extension portion and the second extension portion, and the third agent-dipped adhesive section bypasses the support body in the thickness direction of the support body. This allows the first, second, and third agent-dipped adhesive sections to be exposed on the outside of the support body. In the dipping process during the production of electronic detonators, this facilitates the contact and adhesion of the ignition agent with the first, second, and third agent-dipped adhesive sections.
[0016] According to one embodiment of this application, the first conductive connection portion and the second conductive connection portion are arranged back to back in the thickness direction of the support body, the first drug-adhesive segment and the second drug-adhesive segment are arranged back to back in the thickness direction of the support body, the third drug-adhesive segment is connected between the first extension portion and the second extension portion, and the vertical center planes of the first drug-adhesive segment, the second drug-adhesive segment and the third drug-adhesive segment are located in the same vertical plane in the thickness direction of the support body.
[0017] In this embodiment, the first and second chemical adhesive sections are arranged back-to-back in the thickness direction of the support body. The vertical center planes of the first, second, and third chemical adhesive sections are located on the same vertical plane in the thickness direction of the support body. This facilitates a compact arrangement of the first, second, and third chemical adhesive sections in the width direction of the support body, reducing their distribution range in the width direction. Furthermore, this reduces interference from other components during the chemical dipping process in the production of electronic detonators.
[0018] According to one embodiment of this application, the first drug-adhesive segment abuts against a first surface in the thickness direction of the support body, and the first surface in the thickness direction of the support body provides support for the first drug-adhesive segment. The second drug-adhesive section abuts against the second surface of the support body in the thickness direction, and the second surface of the support body in the thickness direction provides support for the second drug-adhesive section. The third drug-adhesive section abuts against the end face of the support body along its length, and the end face of the support body along its length that abuts against the third drug-adhesive section provides support for the third drug-adhesive section.
[0019] In this embodiment, the first surface of the support body in the thickness direction provides support for the first chemical coating and adhesion section, which helps ensure the rigidity of the first chemical coating and adhesion section; the second surface of the support body in the thickness direction provides support for the second chemical coating and adhesion section, which helps ensure the rigidity of the second chemical coating and adhesion section; the end face of the support body in the length direction, which abuts against the third chemical coating and adhesion section, provides support for the third chemical coating and adhesion section, which helps ensure the rigidity of the third chemical coating and adhesion section; in the production process such as the chemical coating process in the production of electronic detonators, the first chemical coating and adhesion section, the second chemical coating and adhesion section, and the third chemical coating and adhesion section are supported by the support body, which helps to avoid ignition bridge wire. Furthermore, in this embodiment, the ignition assembly is placed inside the electronic detonator. When the ignition assembly in this embodiment is subjected to blasting vibrations from the previous electronic detonator during the blasting process, the support body provides support for the first, second, and third agent-dipping adhesion sections, thereby improving the vibration resistance and damage resistance of the first, second, and third agent-dipping adhesion sections, preventing them from being broken by impact, and thus preventing the ignition bridge wire from breaking and causing the electronic detonator to misfire.
[0020] According to one embodiment of this application, the first drug-adhesive segment is a straight segment, the second drug-adhesive segment is a straight segment, and the third drug-adhesive segment is a straight segment or a curved segment.
[0021] When the first, second, and third drug-adhesive segments in this embodiment are all straight segments, it is beneficial for them to be set close to the support body, making it easier for the support body to fully support the first, second, and third drug-adhesive segments, thereby improving their vibration resistance and damage resistance. When the first and second drug-adhesive segments in this embodiment are straight segments and the third drug-adhesive segment is curved, it is beneficial to reduce the degree of bending at the connection between the third drug-adhesive segment and the first and second drug-adhesive segments, thereby preventing the connection between the third drug-adhesive segment and the first and second drug-adhesive segments from being excessively bent and breaking.
[0022] According to one embodiment of this application, the length of the first drug-adhesive section is any value between 2.0mm and 5.0mm, the length of the second drug-adhesive section is any value between 2.0mm and 5.0mm, and the length of the third drug-adhesive section is any value between 0.8mm and 3.0mm.
[0023] In this embodiment, the length of the first agent-dipping adhesive section is any value between 2.0mm and 5.0mm. This suitable length ensures that the first agent-dipping adhesive section has sufficient length to pick up the ignition agent while preventing it from becoming excessively long. Furthermore, in this embodiment, the length of the second agent-dipping adhesive section is any value between 2.0mm and 5.0mm. This suitable length ensures that the second agent-dipping adhesive section has sufficient length to pick up the ignition agent while preventing it from becoming excessively long. Firstly, the length of the third agent-dipping and adhering section is any value between 0.8mm and 3.0mm. The suitable length of the third agent-dipping and adhering section is beneficial for the third agent-dipping and adhering section to wrap around from the first surface in the thickness direction of the support body to the second surface in the thickness direction of the support body. This ensures that the third agent-dipping and adhering section has sufficient length to dip into the ignition agent while avoiding excessive length. Furthermore, the suitable lengths of the first, second, and third agent-dipping and adhering sections are beneficial for ensuring that the ignition bridge wire has sufficient length to achieve reliable ignition.
[0024] According to one embodiment of this application, the width of the ignition bridge wire is any value between 0.15mm and 0.50mm, and the width of the support body is any value between 2.0mm and 4.0mm.
[0025] In this embodiment, the width of the support body is any value between 2.0mm and 4.0mm, and the width of the ignition bridge wire is any value between 0.15mm and 0.50mm. The width of the support body is larger than the width of the ignition bridge wire, which is beneficial for placing the ignition bridge wire on the support body and for the support body to provide reliable support for the ignition bridge wire. Furthermore, in the dipping process of electronic detonators, and during the contact between the ignition bridge wire and the ignition agent, it is convenient for the part of the support body near the ignition bridge wire to also contact the ignition agent, increasing the area of the ignition agent dipped by the ignition component. This is beneficial for increasing the amount of ignition agent dipped by the ignition component in one dipping process, thereby facilitating the ignition component to quickly dip and obtain an appropriate amount of ignition agent, which is beneficial for improving the dipping efficiency of the ignition component, and also helps to ensure that sufficient ignition agent is ignited when ignited by the ignition component in the subsequent ignition, thereby achieving reliable ignition.
[0026] According to one embodiment of this application, the ignition assembly for an electronic detonator further includes: The circuit board substrate has a long plate-like structure, and one end of the circuit board substrate extends along its length to form the support body.
[0027] In this embodiment, one end of the circuit board substrate extends along its length to form a support body, which facilitates the integral connection between the support body and the circuit board substrate, makes it easier to process and obtain the support body, and can eliminate the workload and cost required to connect the support body to the circuit board substrate, and can also improve the reliability of the connection between the support body and the circuit board substrate.
[0028] According to one embodiment of this application, the ignition assembly for an electronic detonator further includes: A circuit board substrate, wherein the circuit board substrate has a long plate-like structure, and the support body is connected to one end of the circuit board substrate along its length.
[0029] In this embodiment, the support body is connected to one end of the circuit board substrate along its length, which facilitates the separate production of the support body and the circuit board substrate. The ignition bridge wire is placed on the support body, and then the support body with the ignition bridge wire is dipped in a chemical coating process. The dipped support body is then connected to the circuit board substrate. This process optimizes the production process of the electronic detonator and allows the support body with the ignition bridge wire to be used as an intermediate product.
[0030] According to another aspect of this application, an electronic detonator control module is provided, comprising: The aforementioned ignition assembly for electronic detonators; The circuit board substrate is a long plate-shaped structure. One end of the circuit board substrate extends in the length direction to form the support body or the support body is connected to one end of the circuit board substrate in the length direction. A control circuit is provided on the circuit board substrate, and part of the circuit of the control circuit is provided on the support body. An energy storage capacitor is placed on the circuit board substrate.

[0031] The electronic detonator control module in this embodiment includes the aforementioned ignition assembly for the electronic detonator. This facilitates support for the ignition bridge wire via the support body, reducing or even eliminating the ignition bridge wire from being suspended. By placing the electronic detonator control module inside the electronic detonator, when the ignition assembly is subjected to blasting vibrations from a previously blasted electronic detonator during detonation, the support body provides support for the ignition bridge wire and improves its vibration and damage resistance, preventing it from breaking due to impact and thus avoiding misfires caused by the broken ignition bridge wire. In one step, a portion of the length of the ignition bridge wire is provided on the first side of the support body in the thickness direction, and a portion of the length of the ignition bridge wire is also provided on the second side of the support body in the thickness direction. This means that the length of the ignition bridge wire is provided on both sides of the support body in the thickness direction. This is beneficial for setting the ignition component in this embodiment inside the electronic detonator and achieving double-sided ignition through the ignition bridge wire. This avoids the problem of partial detonation of the detonator due to single-sided ignition. It is also beneficial for providing sufficient ignition power to detonate the electronic detonator through double-sided ignition, thereby avoiding mis-detonation of the electronic detonator. This is beneficial for improving the reliability and stability of the detonation of the electronic detonator containing the electronic detonator control module of this embodiment.

[0033] In this embodiment, the first conductive contact for resistance detection is electrically connected to the first conductive connection via circuit one, and the second conductive contact for resistance detection is electrically connected to the second conductive connection via circuit two. This facilitates the detection of the resistance of the ignition bridge wire by having a pair of resistance detection probes connected to the resistance detection device contact the first and second conductive contacts for resistance detection, thereby enabling the verification of the resistance of the ignition bridge wire.
[0034] According to another aspect of this application, an electronic detonator is provided, comprising: The detonator housing has an interconnected mounting cavity, an initiating explosive filling cavity, and a base explosive filling cavity. The initiating explosive filling cavity is filled with initiating explosive, and the base explosive filling cavity is filled with base explosive. The aforementioned electronic detonator control module is installed in the mounting cavity. The ignition bridge wire extends into the detonator filling cavity and contacts the detonator filling cavity. The ignition bridge wire is electrically connected to the electronic detonator control module and can be ignited under the control of the electronic detonator control module. When the ignition bridge wire is ignited under the control of the electronic detonator control module, the ignition bridge wire detonates the detonator filling cavity, and the detonated detonator can detonate the base charge filling cavity.
[0035] The electronic detonator in this embodiment includes the aforementioned electronic detonator control module. The ignition bridge wire extends into the detonator filling cavity and contacts the detonator filling the cavity. During the detonation process, when the ignition assembly is subjected to the blasting vibration produced by the previous electronic detonator, the support body provides support for the ignition bridge wire and improves its vibration and damage resistance, preventing the ignition bridge wire from being broken by impact, thereby preventing the electronic detonator from mis-detonating due to the breakage of the ignition bridge wire; furthermore, the first [missing information - likely a measurement or feature] in the thickness direction of the support body... The first side has a portion of the length of the ignition bridge wire, and the second side in the thickness direction of the support body also has a portion of the length of the ignition bridge wire. This means that both sides in the thickness direction of the support body have lengths of the ignition bridge wire, which is beneficial for setting the ignition assembly in this embodiment inside the electronic detonator and achieving double-sided ignition through the ignition bridge wire.

It avoids the problem of partial explosion of the charge head caused by single-sided ignition and provides sufficient ignition power to detonate the electronic detonator through double-sided ignition, thereby avoiding mis-explosion of the electronic detonator.

When the ignition assembly in this embodiment is subjected to the blasting vibration produced by the blasting of the electronic detonator in the process of blasting, the support body 10 provides support for the first agent-dipping adhesion section 40, the second agent-dipping adhesion section 41, and the third agent-dipping adhesion section 42, thereby improving the vibration resistance and damage resistance of the first agent-dipping adhesion section 40, the second agent-dipping adhesion section 41, and the third agent-dipping adhesion section 42, and avoiding the first agent-dipping adhesion section 40, the second agent-dipping adhesion section 41, and the third agent-dipping adhesion section 42 from being broken by impact, thereby avoiding the ignition bridge wire 4 breaking and causing the electronic detonator to misfire.
[0056] In this embodiment, as Figures 2 to 6 As shown, the first surface of the support body 10 in the thickness direction is the upper surface of the support body 10, which abuts against the lower surface of the first drug-adhesive section 40, providing support for the first drug-adhesive section 40; the second surface of the support body 10 in the thickness direction is the lower surface of the support body 10, which abuts against the upper surface of the second drug-adhesive section 41, providing support for the second drug-adhesive section 41; the rear end surface of the support body 10 abuts against the front surface of the third drug-adhesive section 42, providing support for the third drug-adhesive section 42.
[0057] Furthermore, such as Figures 2 to 6 As shown, in this embodiment, the first drug-adhesive section 40, the second drug-adhesive section 41, and the third drug-adhesive section 42 are all cylindrical. The shapes of the first drug-adhesive section 40, the second drug-adhesive section 41, and the third drug-adhesive section 42 can also be set to other shapes as needed.

[0059] Furthermore, in this embodiment, the third drug-adhesive segment 42 can also be set as a curved segment.
[0060] In this embodiment, as Figures 2 to 6 As shown, when the first drug-adhesive segment 40, the second drug-adhesive segment 41, and the third drug-adhesive segment 42 in this embodiment are all straight segments, it is beneficial for the first drug-adhesive segment 40, the second drug-adhesive segment 41, and the third drug-adhesive segment 42 to be set against the support body 10. This facilitates the support body 10 to fully support the first drug-adhesive segment 40, the second drug-adhesive segment 41, and the third drug-adhesive segment 42, thereby improving the adhesion of the first drug-adhesive segment 40, the second drug-adhesive segment 41, and the third drug-adhesive segment 42. The vibration resistance and damage resistance of the drug-adhesive segment 42; when the first drug-adhesive segment 40 and the second drug-adhesive segment 41 in this embodiment are straight segments and the third drug-adhesive segment 42 is a curved segment, it is beneficial to reduce the degree of bending of the connection between the third drug-adhesive segment 42 and the first drug-adhesive segment 40 and the second drug-adhesive segment 41 respectively, and to avoid excessive bending and breakage of the connection between the third drug-adhesive segment 42 and the first drug-adhesive segment 40 and the second drug-adhesive segment 41 respectively.
[0061] It should be noted that in this embodiment, the ignition bridge wire 4 with the third agent dipping and adhesion section 42 set as a curved section is not illustrated. When the third agent dipping and adhesion section 42 is set as a curved section, the third agent dipping and adhesion section 42 can be set as an arc shape, etc.
[0062] One embodiment of this application, such as Figure 2 and Figure 3 As shown, the length of the first drug-adhesive section 40 is any value between 2.0mm and 5.0mm, the length of the second drug-adhesive section 41 is any value between 2.0mm and 5.0mm, and the length of the third drug-adhesive section 42 is any value between 0.8mm and 3.0mm.
[0063] In this embodiment, as Figure 2 and Figure 3As shown, in this embodiment, the length of the first agent-dipping adhesion section 40 is any value between 2.0mm and 5.0mm. This suitable length ensures that the first agent-dipping adhesion section 40 has sufficient length to absorb the ignition agent while preventing it from becoming excessively long. Furthermore, in this embodiment, the length of the second agent-dipping adhesion section 41 is any value between 2.0mm and 5.0mm. This suitable length ensures that the second agent-dipping adhesion section 41 has sufficient length to absorb the ignition agent while preventing it from becoming excessively long. The length of the third agent-dipping adhesion section 42 is any value between 0.8mm and 3.0mm. The suitable length of the third agent-dipping adhesion section 42 is beneficial for the third agent-dipping adhesion section 42 to wrap around from the first surface of the support body 10 in the thickness direction to the second surface of the support body 10 in the thickness direction. This ensures that the third agent-dipping adhesion section 42 has sufficient length to dip in the ignition agent while avoiding the third agent-dipping adhesion section 42 being too long. Furthermore, the suitable lengths of the first agent-dipping adhesion section 40, the second agent-dipping adhesion section 41, and the third agent-dipping adhesion section 42 are beneficial for ensuring that the ignition bridge wire 4 has sufficient length to achieve reliable ignition.
[0064] In this embodiment, as Figure 2 and Figure 3 As shown, in the production process of electronic detonators, such as the dipping process, the ignition bridge wire 4 is inserted into the dipping container storing the ignition agent, so that the first agent dipping adhesion section 40, the second agent dipping adhesion section 41, and the third agent dipping adhesion section 42 of the ignition bridge wire 4 come into contact with the ignition agent stored in the dipping container, and the ignition agent adheres to the first agent dipping adhesion section 40, the second agent dipping adhesion section 41, and the third agent dipping adhesion section 42. Furthermore, in subsequent production processes, the ignition agent adhering to the first agent dipping adhesion section 40, the second agent dipping adhesion section 41, and the third agent dipping adhesion section 42 is dried, so that the ignition agent adhering to the first agent dipping adhesion section 40, the second agent dipping adhesion section 41, and the third agent dipping adhesion section 42 is dry. It should be noted that the relevant operations of the dipping process and the ignition agent can refer to the prior art in this field, and will not be described in detail here.
[0065] One embodiment of this application, such as Figures 2 to 6 As shown, the width of the ignition bridge wire 4 is any value between 0.15mm and 0.50mm, and the width of the support body 10 is any value between 2.0mm and 4.0mm.
[0066] In this embodiment, as Figures 2 to 6 As shown, in this embodiment, the width of the support body 10 is any value between 2.0mm and 4.0mm, and the width of the ignition bridge wire 4 is any value between 0.15mm and 0.50mm. The width of the support body 10 is greater than the width of the ignition bridge wire 4, which is beneficial for setting the ignition bridge wire 4 on the support body 10 and for the support body 10 to provide reliable support for the ignition bridge wire 4. Furthermore, in the dipping process of the electronic detonator, and during the contact between the ignition bridge wire 4 and the ignition agent, it is convenient for the part of the support body 10 near the ignition bridge wire 4 to also contact the ignition agent, increasing the area of the ignition agent dipped by the ignition component. This is beneficial for increasing the amount of ignition agent dipped by the ignition component in one dipping process, thereby facilitating the ignition component to quickly dip and obtain an appropriate amount of ignition agent, which is beneficial for improving the dipping efficiency of the ignition component and ensuring that sufficient ignition agent is ignited when ignited by the ignition component in the subsequent process, thus achieving reliable ignition.
[0067] The ignition assembly in this embodiment, compared to the traditional ignition bridge wire assembly, such as Figure 1 As shown, a traditional ignition bridge wire assembly includes a pair of parallel metal connecting bridges 7 and an ignition bridge wire 8 connected between the pair of metal connecting bridges 7. The middle of the ignition bridge wire 8 is suspended. The pair of metal connecting bridges 7 are connected to one end of a circuit board equipped with a control circuit. The ignition bridge wire 8 is controlled by the control circuit to achieve ignition. However, the metal connecting bridges 7 are small in size and have a small area, which is insufficient to provide enough area for the ignition agent to adhere. Multiple dipping is required to meet the requirements, resulting in low dipping efficiency. Moreover, the small size of the metal connecting bridges 7 results in poor rigidity. During the dipping process in the production of electronic detonators, they are easily subjected to external forces, causing bending and deformation, which can easily lead to damage to the ignition bridge wire 8. Therefore, the ignition assembly in this embodiment avoids the problem of easy breakage of traditional ignition bridge wire assemblies and improves the dipping efficiency of the ignition assembly.

[0069] In this embodiment, as Figures 2 to 6 As shown, in this embodiment, one end of the circuit board substrate 1 extends in the length direction to form a support body 10, which is beneficial for the support body 10 to be integrally connected with the circuit board substrate 1, facilitates the processing of the support body 10, and can eliminate the workload and cost required to connect the support body 10 to the circuit board substrate 1, and can also improve the reliability of the connection between the support body 10 and the circuit board substrate 1.
[0070] In this embodiment, as Figures 2 to 6 As shown, the circuit board substrate 1 has a long plate-like structure, specifically meaning that the length of the circuit board substrate 1 is three times or more the width. In this embodiment, the circuit board substrate 1 is approximately rectangular.
[0071] In this embodiment, as Figures 2 to 6 As shown, the support body 10 and the circuit board substrate 1 are integrally formed. The support body 10 is a part of the circuit board substrate 1. The support body 10 is formed during the processing of the circuit board substrate 1. It should be noted that the width of the support body 10 in this embodiment is designed to be smaller than the width of the circuit board substrate 1. If necessary, the width of the support body 10 can also be designed to be equal to the width of the circuit board substrate 1.
[0072] In one embodiment of this application, the ignition assembly for an electronic detonator further includes: The circuit board substrate 1 has a long plate-shaped structure, and the support body 10 is connected to one end of the circuit board substrate 1 along its length.
[0073] In this embodiment, the support body 10 is connected to one end of the circuit board substrate 1 along its length, which facilitates the separate production of the support body 10 and the circuit board substrate 1. The ignition bridge wire 4 is placed on the support body 10. The support body 10 with the ignition bridge wire 4 is then dipped in a chemical coating process. The dipped support body 10 is then connected to the circuit board substrate 1. This optimizes the production process of the electronic detonator and allows the support body 10 with the ignition bridge wire 4 to be used as an intermediate product.
[0074] In this embodiment, the ignition assembly consisting of the support body 10 as an independent component connected to the circuit board substrate 1 is not illustrated. When the support body 10 is an independent component, there are various ways to connect the support body 10 to the circuit board substrate 1, which will not be described in detail here.

The control chip is mounted on the circuit board substrate 1 and is electrically connected to the control circuit. The electronic components are provided in multiple forms and are disposed on the circuit board substrate 1. The electronic components are electrically connected to the control circuit. The wiring terminal is connected to the other end of the circuit board substrate 1 along its length and is electrically connected to the control circuit.
[0076] In this embodiment, as Figures 2 to 6 As shown, the electronic detonator control module in this embodiment includes the aforementioned ignition assembly for the electronic detonator. This facilitates support for the ignition bridge wire 4 via the support body 10, reducing or even eliminating the suspended length of the ignition bridge wire 4. By placing the electronic detonator control module inside the electronic detonator, when the ignition assembly is subjected to blasting vibrations from a previously blasted electronic detonator during detonation, the support body 10 provides support for the ignition bridge wire 4 and enhances its vibration and damage resistance, preventing it from breaking due to impact. This avoids the ignition bridge wire 4 breaking and causing a misfire in the electronic detonator. Furthermore, the first surface of the support body 10 in the thickness direction is provided with a portion of the length of the ignition bridge wire 4, and the second surface of the support body 10 in the thickness direction is also provided with a portion of the length of the ignition bridge wire 4. This means that both surfaces of the support body 10 in the thickness direction are provided with the length of the ignition bridge wire 4. This is beneficial for setting the ignition component in this embodiment inside the electronic detonator and achieving double-sided ignition through the ignition bridge wire 4, avoiding the problem of partial detonation of the detonator due to single-sided ignition. It is also beneficial for providing sufficient ignition power through double-sided ignition to detonate the electronic detonator, thereby avoiding mis-detonation of the electronic detonator. This is beneficial for improving the reliability and stability of the detonation of the electronic detonator containing the electronic detonator control module of this embodiment.

The specific way in which each electronic component is connected to the circuit board substrate 1 can also refer to the prior art, and will not be described in detail here.
[0080] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the electronic detonator control module in this embodiment also includes a sealing body 6, which is formed by injection molding. The sealing body 6 formed by injection molding encapsulates the entire energy storage capacitor and also encapsulates the electronic components mounted on the circuit board substrate 1. The wiring terminals are exposed on the outside of the sealing body 6. The injection molding process can refer to the existing electronic detonator control modules in the art, and will not be described in detail here.
[0081] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the outer side of the sealant body 6 is formed with a first groove 60, a second groove 61, and a third groove 62. There are two first grooves 60, which are located on the left and right sides of the sealant body 6, respectively. The second groove 61 and the third groove 62 are located on the lower side wall of the sealant body 6. The second groove 61 and the third groove 62 are crescent-shaped. The second groove 61 and the third groove 62 can also be set to other shapes.
[0082] One embodiment of this application, such as Figure 5 and Figure 6 As shown, the circuit board substrate 1 is provided with a first conductive contact 11 for resistance detection and a second conductive contact 12 for resistance detection. The first conductive contact 11 for resistance detection is electrically connected to the first conductive connection 2 through a circuit 1, and the second conductive contact 12 for resistance detection is electrically connected to the second conductive connection 3 through a circuit 2.

This facilitates the detection of the resistance of the ignition bridge wire 4 by having a pair of resistance detection probes connected to the resistance detection device contact the first conductive contact 11 and the second conductive contact 12, thereby facilitating the verification of the resistance of the ignition bridge wire 4.
[0084] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the first conductive contact 11 for resistance detection is specifically a first conductive pad, and the second conductive contact 12 for resistance detection is specifically a second conductive pad. The first conductive pad and the second conductive pad are soldered to the lower side of the circuit board substrate 1, and the first conductive pad and the second conductive pad are exposed on the outside of the encapsulant 6. The first conductive contact 11 and the second conductive contact 12 for resistance detection can also be configured as other conductive contact structures. Furthermore, the first circuit and the second circuit can be configured in various ways. The first circuit and the second circuit can be configured as part of the control circuit, or the first circuit and the second circuit can be configured independently relative to the control circuit. It should be noted that the first circuit and the second circuit are not illustrated in this embodiment.
[0085] In another aspect, this application provides an electronic detonator comprising: The detonator casing contains an interconnected mounting cavity, an initiating explosive filling cavity, and a base explosive filling cavity. The initiating explosive filling cavity is filled with initiating explosive, and the base explosive filling cavity is filled with base explosive. The aforementioned electronic detonator control module is installed in the mounting cavity. The ignition bridge wire 4 extends into the detonator filling cavity and contacts the detonator filling cavity. The ignition bridge wire 4 is electrically connected to the electronic detonator control module and can be ignited under the control of the electronic detonator control module. When the ignition bridge wire 4 is ignited under the control of the electronic detonator control module, the ignition bridge wire 4 detonates the detonator filling cavity, and the detonated detonator can detonate the basic charge filling cavity.
[0086] In this embodiment, the electronic detonator includes the aforementioned electronic detonator control module. The ignition bridge wire 4 extends into the detonating charge filling cavity and contacts the detonating charge filling the cavity. During the detonation process, when the ignition assembly is subjected to the blasting vibration produced by the previous electronic detonator blast, the support body 10 provides support for the ignition bridge wire 4 and improves its vibration resistance and damage resistance, preventing the ignition bridge wire 4 from being broken by impact, thereby preventing the electronic detonator from mis-blasting due to the breakage of the ignition bridge wire 4. Furthermore, the thickness of the support body 10 is... The first side of the support body 10 has a portion of the length of the ignition bridge wire 4, and the second side of the support body 10 in the thickness direction also has a portion of the length of the ignition bridge wire 4. This means that the ignition bridge wire 4 is provided on both sides of the support body 10 in the thickness direction.
