Description

Technical Field

[0001] This utility model relates to the field of pyrotechnics technology, and in particular to a circuit board structure and an electronic detonator control module and an electronic detonator containing the same. 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, plastic plugs, control modules, ignition bridge wires with ignition charge, base charge, and base casing. In addition, during the production of electronic detonators, the control module needs to be assembled into a protective casing to protect the control module.

[0003] Furthermore, in the electronic detonator industry, the outer diameter of electronic detonators is generally specified as 7.0mm-7.2mm. The protective 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 protective housing. Moreover, when the width of the control module is greater than the inner diameter of the protective housing, it is difficult to assemble the control module into the protective housing.

[0004] Furthermore, the outer side of the control module needs to be encapsulated by injection molding to form an encapsulation layer. The thickness of the encapsulation layer must at least cover the energy storage capacitor mounted on the circuit board, and the thickness of the encapsulation layer can be controlled within a certain range. Therefore, the width of the control module is mainly determined by the width of the circuit board and the protrusion of the energy storage capacitor mounted on the circuit board. After the energy storage capacitor is mounted on the circuit board, the size of the protrusion of the energy storage capacitor from the circuit board affects the width of the control module.

[0005] To reduce the protrusion of the energy storage capacitor from the circuit board, existing technologies mount the energy storage capacitor in a capacitor placement slot on the circuit board. This can limit the width of the control module to a suitable range to some extent. However, the circuit board used for the control module is relatively narrow, and due to inherent design flaws in the existing circuit board structure, the energy storage capacitor mounted in the capacitor placement slot is easily damaged or even fails, leading to damage or failure of the control module, reducing the yield rate of the control module, and also reducing the blasting effect of electronic detonators. Therefore, ensuring the reliability and stability of the energy storage capacitor mounted in the capacitor placement slot on the circuit board has become a new challenge.

[0006] Furthermore, to ensure the capacitor placement slot has a suitable width to accommodate the energy storage capacitor, the sides of the circuit board used in the control module often have a narrow width, which can easily lead to breakage of these sides. This affects the reliability of the circuit board structure and consequently the reliability and stability of the energy storage capacitor installed in the slot. Additionally, the circuit board is built upon a circuit board substrate to create a complete electronic connection system; the structure of the circuit board substrate largely determines the structure of the circuit board. Therefore, there is an urgent need for a circuit board structure that minimizes the size of the energy storage capacitor protruding from the circuit board substrate while improving its reliability and stability. Summary of the Invention

[0007] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a circuit board structure that is advantageous in reducing the size of the energy storage capacitor protruding from the circuit board structure and improving the reliability and stability of the energy storage capacitor; in addition, it also provides an electronic detonator control module and an electronic detonator.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0009] According to one aspect of this application, a circuit board structure is provided, comprising:

[0010] The body is a long plate-shaped structure with a placement slot for placing an energy storage capacitor. The placement slot extends along the length of the body. A wide-side bridge is formed on one side of the placement slot in the width direction, and a narrow-side bridge is formed on the other side of the placement slot in the width direction. The narrow-side bridge is positioned opposite the wide-side bridge. The width of the wide-side bridge is greater than the width of the narrow-side bridge. When the energy storage capacitor is placed in the placement slot, it is located inside the placement slot in the horizontal direction.

[0011] A narrow-side strength enhancement structure is disposed on the narrow-side bridge, and the narrow-side strength enhancement structure is used to enhance the strength of the narrow-side bridge.

[0012] The beneficial effects of this utility model are as follows: In this embodiment, a wide-side bridge is formed on one side of the body in the width direction of the placement slot, and a narrow-side bridge is formed on the other side of the body in the width direction of the placement slot. The narrow-side bridge is provided with a narrow-side strength reinforcement structure to enhance its strength. This facilitates strengthening the narrow-side bridge through the narrow-side strength reinforcement structure, ensuring its strength. In addition, the width dimension of the wide-side bridge is relatively wider than that of the narrow-side bridge. The wide-side bridge can ensure its strength through its relatively wider width dimension, which helps to prevent the wide-side bridge and the narrow-side bridge from breaking. Furthermore, when arranging the circuit on the body, the conductive lines constituting the circuit can be arranged on the wide-side bridge. This facilitates the arrangement of conductive lines on the wide-side bridge passing through one side of the placement slot on the body, and also helps to increase the distance between the conductive lines arranged on the wide-side bridge on one side of the placement slot and the energy storage capacitor placed in the placement slot. This helps to avoid the adverse effects of static electricity or other electrical energy flowing through the conductive lines arranged on one side of the placement slot on the energy storage capacitor, thereby improving the reliability and stability of the energy storage capacitor. It also helps to reduce the difficulty of arranging conductive lines on one side of the placement slot. Furthermore, the narrow-side bridge in this embodiment can provide support for the outer wall of the energy storage capacitor that is directly opposite it. The energy storage capacitor can be confined between the wide-side bridge and the narrow-side bridge in the width direction and can achieve the lifting and positioning of the wide-side bridge and the narrow-side bridge, improving the accuracy of the energy storage capacitor installed on the body. It also helps to reduce the size of the energy storage capacitor protruding from the body and improve the reliability of the energy storage capacitor confined in the placement slot. Therefore, the production of the electronic detonator control module using the circuit board structure in this embodiment helps to improve the yield of the electronic detonator control module and improve the blasting effect of electronic detonator blasting operations.

[0013] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0014] According to one embodiment of the present invention, the narrow-side strength enhancement structure includes:

[0015] A copper cladding layer is applied to the narrow side bridge along the length of the narrow side bridge.

[0016] The narrow-side strength enhancement structure in this embodiment includes a copper-clad layer, which facilitates the application of copper foil on the narrow-side bridge to obtain the copper-clad layer, thereby reducing the setup cost of the narrow-side strength enhancement structure.

[0017] According to one embodiment of the present invention, the copper cladding layer is applied to the upper and / or lower surface of the narrow-side bridge.

[0018] In this embodiment, when the copper clad layer is applied to the upper or lower surface of the narrow-side bridge, the copper clad layer is applied only to one side of the narrow-side bridge, which helps to reduce the workload of applying the copper clad layer. When the copper clad layer is applied to both the upper and lower surfaces of the narrow-side bridge, the copper clad layer is applied to both the upper and lower surfaces of the narrow-side bridge, which helps to further enhance the strength of the narrow-side bridge through the copper clad layer, thereby further improving the fracture resistance of the narrow-side bridge.

[0019] According to one embodiment of the present invention, the two ends of the copper cladding layer extend beyond the placement slot in the length direction.

[0020] In this embodiment, the copper cladding layer extends beyond the placement slot at both ends along its length, so that the ends of the narrow bridge near the placement slot have a copper cladding layer to enhance its strength. This ensures the strength of the ends of the narrow bridge near the placement slot along its length, which is beneficial to improving the fracture resistance of the narrow bridge.

[0021] According to one embodiment of the present invention, the narrow-side strength enhancement structure includes:

[0022] A strength-enhancing colloid, which is bonded to the narrow-side bridge, and is formed by curing a strength-enhancing adhesive or strength-enhancing glue added to the narrow-side bridge.

[0023] The narrow-edge strength enhancement structure in this embodiment includes a strength enhancement colloid, which facilitates the flexible addition of strength enhancement adhesive or strength enhancement glue to the narrow-edge bridge to cure and form a strength enhancement colloid, and also helps to reduce the amount of processing required for the circuit board structure.

[0024] According to one embodiment of the present invention, the narrow-side strength enhancement structure includes:

[0025] A narrow-edge strength reinforcement strip is connected to the upper and / or lower surface of the narrow-edge bridge, and both ends of the narrow-edge strength reinforcement strip extend beyond the placement slot in the length direction.

[0026] In this embodiment, by connecting narrow-side strength reinforcement strips to the upper and / or lower surfaces of the narrow-side bridge, it is advantageous to flexibly select suitable narrow-side strength reinforcement strips according to the strength requirements of the narrow-side bridge, and it is also convenient to connect narrow-side strength reinforcement strips to the narrow-side bridge to increase its strength.

[0027] According to one embodiment of the present invention, the placement channel has a rectangular shape and is perpendicular to the body in the width direction. The body is provided with a pair of conductive connecting parts, which are located near the placement channel and on one side of the placement channel in the length direction of the body. The pair of conductive connecting parts are used to connect and conduct electricity with a pair of conductive connecting feet on the energy storage capacitor. After the pair of conductive connecting feet on the energy storage capacitor are connected to the pair of conductive connecting parts, the energy storage capacitor can be placed in the placement channel. When the energy storage capacitor is placed in the placement channel, the upper and lower sidewalls of the energy storage capacitor in the vertical direction protrude from the placement channel.

[0028] In this embodiment, the placement slot is perpendicular to the main body in the width direction. The wide and narrow bridges formed on both sides of the main body in the width direction of the placement slot are elongated, which is beneficial for providing support and constraint for the energy storage capacitor placed in the placement slot, improving the reliability of the energy storage capacitor being confined in the placement slot, and also facilitating the arrangement of conductive lines on the wide bridges, reducing the difficulty of arranging conductive lines on the wide bridges. Furthermore, in this embodiment, a pair of conductive connecting parts are provided on the main body near the placement slot, which facilitates the connection of a pair of conductive connecting feet on the energy storage capacitor to the pair of conductive connecting parts, making it easy to install the energy storage capacitor on the main body and place the energy storage capacitor in the placement slot. Furthermore, in this embodiment, the upper and lower sidewalls of the energy storage capacitor in the vertical direction protrude from the placement slot, which is beneficial for the vertical center plane of the energy storage capacitor to be close to the vertical center plane of the main body. The dimensions of the upper and lower sidewalls of the energy storage capacitor protruding from the placement slot in the vertical direction are equal or equivalent, which helps to reduce the size of the energy storage capacitor protruding from the main body.

[0029] According to one embodiment of the present invention, the width of the wide-side bridge is any value between 0.6mm and 1.6mm, and the width of the narrow-side bridge is any value between 0.3mm and 0.8mm.

[0030] In this embodiment, the width of the wide-side bridge is any value between 0.6mm and 1.6mm, which helps to ensure that the wide-side bridge has a suitable width for arranging conductive lines and reduces the difficulty of arranging conductive lines on the wide-side bridge. Furthermore, the width of the narrow-side bridge is any value between 0.3mm and 0.8mm, which helps to ensure that the narrow-side bridge can provide reliable support for the outer wall of the energy storage capacitor placed opposite it, and improves the reliability of confining the energy storage capacitor within the placement slot. In addition, the suitable width of the wide-side bridge and the narrow-side bridge also helps to ensure that the placement slot has sufficient space in the width direction to accommodate the energy storage capacitor.

[0031] According to another aspect of this application, an electronic detonator control module is provided, comprising:

[0032] The circuit board structure described above;

[0033] The energy storage capacitor is placed in the placement slot. A pair of conductive connecting pins on the energy storage capacitor are connected to the main body, and the energy storage capacitor is electrically connected to the control circuit on the main body through the pair of conductive connecting pins.

[0034] A control chip is disposed on the main body, and the control chip is electrically connected to the control circuit.

[0035] Multiple electronic components are provided and disposed on the main body, and the electronic components are electrically connected to the control circuit.

[0036] A terminal block is connected to one end of the body along its length and is electrically connected to the control circuit.

[0037] An ignition element is connected to the other end of the body along its length and is electrically connected to the control circuit.

[0038] The electronic detonator control module in this embodiment includes the aforementioned circuit board structure, which facilitates the placement of the energy storage capacitor within the placement slot. Furthermore, when arranging the control circuit on the main body, the conductive lines constituting the control circuit can be arranged on the wide-side bridge. This facilitates the arrangement of conductive lines on the wide-side bridge passing through the placement slot on the main body, and increases the distance between the conductive lines arranged on the wide-side bridge and the energy storage capacitor placed within the placement slot. This helps prevent static electricity or other electrical energy flowing through the conductive lines on the wide-side bridge from adversely affecting the energy storage capacitor, improving its reliability and stability. It also reduces the difficulty of arranging conductive lines on one side of the placement slot. Further, the narrow-side bridge is provided with narrow... The edge strength reinforcement structure is beneficial for enhancing the strength of the narrow-side bridge through the narrow-side strength reinforcement structure, ensuring the strength of the narrow-side bridge. In addition, the width dimension of the wide-side bridge is relatively wider than that of the narrow-side bridge. The wider-side bridge can ensure its strength through its relatively wider width, which helps to prevent the wide-side bridge and the narrow-side bridge from breaking. It also helps to provide support for the outer wall of the energy storage capacitor that is placed opposite it through the narrow-side bridge. The energy storage capacitor can be confined between the wide-side bridge and the narrow-side bridge in the width direction and can be lifted and positioned by the wide-side bridge and the narrow-side bridge, improving the accuracy of the energy storage capacitor installation on the body. It also helps to reduce the size of the energy storage capacitor protruding from the body and improve the reliability of the energy storage capacitor being confined in the placement slot. In this way, the quality and yield of the electronic detonator control module are improved, and the blasting effect of electronic detonator blasting operations is improved.

[0039] According to one embodiment of the present invention, the control circuit includes:

[0040] A control circuit unit is arranged on the main body and located on one side of the placement slot in the longitudinal direction of the main body;

[0041] Control circuit section two is arranged on the main body and located on the other side of the placement slot in the length direction of the main body;

[0042] Control circuit section three is arranged on the wide-side bridge and electrically connected between control circuit section one and control circuit section two.

[0043] In this embodiment, by arranging control circuit section one on one side of the placement slot of the main body, control circuit section two on the other side of the placement slot of the main body, and control circuit section three on the wide-side bridge, it is beneficial to distribute the control circuits on the main body, avoiding excessively dense control circuit layout which could lead to leakage between conductive lines on the control circuits and affect the stability and reliability of the control circuits. It is also convenient to arrange electronic components at both ends of the main body, making full use of the usable area of ​​the main body to arrange conductive lines and electronic components. Furthermore, it is beneficial to further reduce the size of the main body while meeting the space requirements for circuit layout.

[0044] According to one embodiment of the present invention, the wide-side bridge has a gap between itself and the outer wall of the energy storage capacitor disposed opposite it in the width direction, forming a gap I. The size of the gap I is any value between 0.1mm and 0.3mm. After the body and the energy storage capacitor are injection molded and sealed, a sealing layer I is formed in the gap I.

[0045] The narrow-sided bridge has a gap two between its width direction and the outer wall of the energy storage capacitor directly opposite it, the size of the gap two being any value between 0.1mm and 0.3mm. After the body and the energy storage capacitor are injection molded and sealed, a sealing layer two is formed in the gap two, and the outer wall of the energy storage capacitor directly opposite the narrow-sided bridge is supported by the sealing layer two and the narrow-sided bridge.

[0046] In this embodiment, the size of gap one is any value between 0.1mm and 0.3mm. The size of gap one is suitable. After the body and the energy storage capacitor are injection molded and sealed, a sealing layer one is formed in gap one. This is beneficial for the sealing layer one formed after injection molding to have a suitable thickness. It is also beneficial for the sealing layer one to block the static electricity or other electrical energy flowing through the conductive lines arranged on the wide side bridge on one side of the placement slot, so as to avoid the static electricity or other electrical energy flowing through the conductive lines arranged on the wide side bridge on one side of the placement slot from having an adverse effect on the energy storage capacitor, thereby improving the reliability and stability of the energy storage capacitor. Furthermore, in this embodiment, the size of gap two is any value between 0.1mm and 0.3mm. The size of gap two is suitable. After the body and the energy storage capacitor are injection molded and sealed, a sealing layer two is formed in gap two. This is beneficial for the sealing layer two formed after injection molding to have a suitable thickness, and it is also beneficial for the sealing layer two and the narrow side bridge to provide reliable support for the outer wall of the narrow side bridge of the energy storage capacitor.

[0047] According to one embodiment of the present invention, the peripheral sidewalls of the energy storage capacitor in the width direction abut against the inner sidewalls of the wide-side bridge and the narrow-side bridge respectively, and the energy storage capacitor is able to be supported and positioned by the wide-side bridge and the narrow-side bridge in the width direction, thereby being confined between the wide-side bridge and the narrow-side bridge.

[0048] In this embodiment, the peripheral sidewalls of the energy storage capacitor in the width direction abut against the inner sidewalls of the wide-side bridge and the narrow-side bridge, respectively. This is beneficial for the energy storage capacitor to be supported and positioned by the wide-side bridge and the narrow-side bridge in the width direction. It is also beneficial for the energy storage capacitor to be supported and positioned by the wide-side bridge and the narrow-side bridge before it is fixed in the placement slot. This makes it easier to accurately install the energy storage capacitor on the body, especially when the energy storage capacitor is attached to the body in a patch-type orientation.

[0049] According to another aspect of this application, an electronic detonator is provided, comprising:

[0050] A housing, wherein a mounting cavity is provided within the housing;

[0051] The aforementioned electronic detonator control module is installed within the mounting cavity.

[0052] The electronic detonator in this embodiment includes the aforementioned electronic detonator control module. This helps to prevent static electricity or other electrical energy flowing through the conductive lines arranged on one side of the placement slot from adversely affecting the energy storage capacitor. It also helps to improve the strength of the wide and narrow bridges, thereby improving the reliability and stability of the energy storage capacitor. In addition, it helps to ensure that the overall width of the electronic detonator control module is within a suitable size range, so that the overall width of the electronic detonator control module matches the size of the mounting cavity in the housing. This facilitates the smooth installation of the electronic detonator control module into the mounting cavity, thereby improving the assembly efficiency of the electronic detonator control module and the quality of the electronic detonator.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] One aspect of this application provides a circuit board structure, such as Figures 1 to 4 As shown, it includes:

[0062] The main body 1 has a long plate-shaped structure and a placement slot 10 for placing the energy storage capacitor 2. The placement slot 10 extends along the length direction of the main body 1. A wide side bridge 13 is formed on one side of the width direction of the placement slot 10, and a narrow side bridge 14 is formed on the other side of the width direction of the placement slot 10. The narrow side bridge 14 is positioned opposite the wide side bridge 13. The width dimension of the wide side bridge 13 is greater than the width dimension of the narrow side bridge 14. When the energy storage capacitor 2 is placed in the placement slot 10, the energy storage capacitor 2 is located inside the placement slot 10 in the horizontal direction.

[0063] A narrow-side strength reinforcement structure is provided on the narrow-side bridge 14 to enhance the strength of the narrow-side bridge 14.

[0064] In this embodiment, as Figures 1 to 4As shown, in this embodiment, the main body 1 forms a wide-side bridge 13 on one side of the width direction of the placement slot 10, and a narrow-side bridge 14 on the other side of the width direction of the placement slot 10. The narrow-side bridge 14 is provided with a narrow-side strength reinforcement structure to enhance its strength. This structure helps to strengthen the narrow-side bridge 14 and ensure its strength. Furthermore, the width of the wide-side bridge 13 is relatively wider than that of the narrow-side bridge 14, allowing the wide-side bridge 13 to maintain its strength and preventing breakage of both the wide-side bridge 13 and the narrow-side bridge 14. Moreover, when arranging circuits on the main body 1, the conductive lines constituting the circuit can be arranged on the wide-side bridge 13. This facilitates the arrangement of conductive lines on the wide-side bridge 13 passing through one side of the placement slot 10 on the main body 1, and increases the interaction between the conductive lines on the wide-side bridge 13 on one side of the placement slot 10 and the energy storage capacitor 2 placed in the placement slot 10. The spacing between the components helps to prevent static electricity or other electrical energy flowing through the conductive lines arranged on the wide-side bridge 13 on one side of the placement slot 10 from adversely affecting the energy storage capacitor 2, thereby improving the reliability and stability of the energy storage capacitor 2. It also helps to reduce the difficulty of arranging conductive lines on one side of the placement slot 10. Furthermore, the narrow-side bridge 14 in this embodiment can provide support for the outer wall of the energy storage capacitor 2 that is directly opposite it. The energy storage capacitor 2 can be confined between the wide-side bridge 13 and the narrow-side bridge 14 in the width direction and can be lifted and positioned by the wide-side bridge 13 and the narrow-side bridge 14, improving the accuracy of the energy storage capacitor 2 installed on the body 1. It also helps to reduce the size of the energy storage capacitor 2 protruding from the body 1 and improve the reliability of the energy storage capacitor 2 confined within the placement slot 10. Therefore, the production of the electronic detonator control module using the circuit board structure in this embodiment helps to improve the yield of the electronic detonator control module and improve the blasting effect of the electronic detonator blasting operation.

[0065] In this embodiment, as Figure 1 and Figure 2 As shown, the body 1 has a long plate-like structure, specifically meaning that the length of the body 1 is three times or more the width. In this embodiment, the body 1 is approximately a rectangular plate-like structure with grooves.

[0066] In this embodiment, the placement slot 10 is formed by cutting. The placement slot 10 can also be formed by other slotting methods. Furthermore, in this embodiment, the body 1 is specifically a PCB substrate. The conductive lines arranged on the body 1 can be designed based on this application and with reference to the PCB substrate in the prior art as needed.

[0067] In this embodiment, as Figure 1 and Figure 2As shown, given a fixed width of the main body 1, in order to ensure that the placement slot 10 can accommodate the energy storage capacitor 2 with a certain width, and given that the width of the energy storage capacitor 2 has a lower limit, if the energy storage capacitor 2 is too small, it will be difficult to ensure that it can provide sufficient power, and it will increase the manufacturing and design cost of the energy storage capacitor 2; therefore, if the width of the narrow side bridge 14 is increased, the width of the wide side bridge 13 needs to be reduced to ensure that the placement slot 10 can accommodate the energy storage capacitor 2 with a certain width. For example, if the width of the body 1 is 4.0 mm and the width of the energy storage capacitor 2 is 3.0 mm, then the sum of the widths of the wide-side bridge 13 and the narrow-side bridge 14 is 1.0 mm. When the width of the narrow-side bridge 14 is 0.3 mm, then the width of the wide-side bridge 13 is 0.7 mm. The conductive lines on the wide-side bridge 13 that pass through the placement slot 10 on the body 1 can only be arranged within a width range of 0.7 mm. It should be noted that the width values ​​of the body 1 in the examples above are only used to explain this application and are not used to limit the actual width of the body 1.

[0068] Furthermore, such as Figure 1 and Figure 2 As shown, the thickness of the body 1 in this embodiment is generally in the range of 0.8mm-1.0mm. The body 1 is relatively thin, and the width of the body 1 and the width of the narrow side bridge 14 are also limited. When the energy storage capacitor 2 is supported by the narrow side bridge 14, the narrow side bridge 14 is prone to breakage without a narrow side strength reinforcement structure. In addition, if a higher strength material is used to produce the body 1, the cost of the circuit board structure will increase. Therefore, in this embodiment, a narrow side strength reinforcement structure is provided on the narrow side bridge 14 to enhance the strength of the narrow side bridge 14 and ensure its strength. The circuit board structure in this embodiment is used to produce the electronic detonator control module, which is beneficial to improving the yield rate of the electronic detonator control module and reducing the production cost of the electronic detonator control module.

[0069] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the narrow-side strength-enhancing structure includes:

[0070] A copper clad layer 141 is applied to the narrow side bridge 14 along the length of the narrow side bridge 14.

[0071] In this embodiment, as Figure 1 and Figure 2 As shown, the narrow-edge strength enhancement structure in this embodiment includes a copper-clad layer 141, which facilitates the application of copper foil on the narrow-edge bridge 14 to obtain the copper-clad layer 141, thereby reducing the setup cost of the narrow-edge strength enhancement structure.

[0072] Furthermore, in this embodiment, a copper-clad layer 141 is obtained by covering the narrow-side bridge 14 with copper foil. The specific process of covering the copper foil on the narrow-side bridge 14 can refer to the prior art process of covering the copper foil on the circuit board. Alternatively, other methods can be used to cover the copper foil on the narrow-side bridge 14 to obtain the copper-clad layer 141. Furthermore, other suitable methods can also be used to cover the copper-clad layer 141 on the narrow-side bridge 14, so that the strength of the narrow-side bridge 14 can be achieved by strengthening the copper-clad layer 141.

[0073] One embodiment of this utility model is as follows: Figures 1 to 4 As shown, the copper clad layer 141 is applied to the upper or lower surface of the narrow-side bridge 14; further, the copper clad layer 141 is applied to both the upper and lower surfaces of the narrow-side bridge 14.

[0074] In this embodiment, as Figures 1 to 4 As shown, when the copper clad layer 141 is applied to the upper or lower surface of the narrow-side bridge 14, the copper clad layer 141 is applied to only one side of the narrow-side bridge 14, which helps to reduce the workload of applying the copper clad layer 141. When the copper clad layer 141 is applied to both the upper and lower surfaces of the narrow-side bridge 14, the copper clad layer 141 is applied to both the upper and lower surfaces of the narrow-side bridge 14, which helps to further enhance the strength of the narrow-side bridge 14 through the copper clad layer 141, thereby further improving the fracture resistance of the narrow-side bridge 14.

[0075] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the two ends of the copper cladding layer 141 extend beyond the placement slot 10 in the length direction.

[0076] In this embodiment, as Figure 1 and Figure 2 As shown, in this embodiment, the two ends of the copper cladding layer 141 in the length direction extend beyond the placement slot 10, so that the two ends of the narrow bridge 14 in the length direction near the placement slot 10 have copper cladding layer 141 to enhance its strength, thereby ensuring the strength of the two ends of the narrow bridge 14 in the length direction near the placement slot 10, which is beneficial to improving the fracture resistance of the narrow bridge 14.

[0077] In one embodiment of this utility model, the narrow-side strength enhancement structure includes:

[0078] A strength-enhancing colloid is bonded to the narrow-sided bridge 14. The strength-enhancing colloid is formed by curing a strength-enhancing adhesive or strength-enhancing glue added to the narrow-sided bridge 14.

[0079] In this embodiment, the narrow-edge strength enhancement structure includes a strength enhancement colloid, which facilitates the flexible addition of strength enhancement adhesive or strength enhancement glue to the narrow-edge bridge 14 to cure and form a strength enhancement colloid, and also helps to reduce the amount of processing required for the circuit board structure.

[0080] Furthermore, there are various ways to add the strength-enhancing adhesive or strength-enhancing glue to the narrow-side bridge 14. The specific operation of adding the strength-enhancing adhesive or strength-enhancing glue to the narrow-side bridge 14 can also be combined with existing technology to facilitate the addition of the strength-enhancing adhesive or strength-enhancing glue to the narrow-side bridge 14, and to facilitate the adhesion of the strength-enhancing colloid formed by the cured strength-enhancing adhesive or strength-enhancing glue to the narrow-side bridge 14, thereby enhancing the strength of the narrow-side bridge 14. Furthermore, the strength-enhancing colloid formed by the cured strength added to the narrow-side bridge 14 is not illustrated in this embodiment. Furthermore, the narrow-side strength-enhancing structure in this embodiment can also adopt other strength-enhancing structures that can enhance the strength of the narrow-side bridge 14. It should be noted that "enhancing the strength of the narrow-side bridge 14" in this embodiment refers to improving the fracture resistance of the narrow-side bridge 14.

[0081] In one embodiment of this utility model, the narrow-side strength enhancement structure includes:

[0082] Narrow-sided strength reinforcing strip is connected to the upper or lower surface of the narrow-sided bridge 14, and both ends of the narrow-sided strength reinforcing strip extend beyond the placement slot 10 in the length direction; further, the narrow-sided strength reinforcing strip is connected to the upper and lower surfaces of the narrow-sided bridge 14.

[0083] In this embodiment, by connecting narrow-side strength reinforcing strips to the upper or lower surface of the narrow-side bridge 14, it is advantageous to flexibly select suitable narrow-side strength reinforcing strips according to the strength requirements of the narrow-side bridge 14, and it is convenient to connect narrow-side strength reinforcing strips to the narrow-side bridge 14 to increase the strength of the narrow-side bridge 14. Furthermore, when narrow-side strength reinforcing strips are connected to the upper and lower surfaces of the narrow-side bridge 14, the strength of the narrow-side bridge 14 can be increased by two narrow-side strength reinforcing strips. In addition, the number of narrow-side strength reinforcing strips connected to the upper or lower surface of the narrow-side bridge 14 can also be adjusted as needed.

[0084] Furthermore, in this embodiment, the narrow-side strength reinforcing strip can be made of metal wire, metal strip, etc. The narrow-side strength reinforcing strip can be bonded to the upper or lower surface of the narrow-side bridge 14 with adhesive. Alternatively, the narrow-side strength reinforcing strip can be bonded to the upper or lower surface of the narrow-side bridge 14 using other suitable connection methods. This facilitates increasing the strength of the narrow-side bridge 14 by connecting the narrow-side strength reinforcing strip to the narrow-side bridge 14. It should be noted that the narrow-side strength reinforcing strip is not illustrated in this embodiment.

[0085] One embodiment of this utility model is as follows: Figures 1 to 4 As shown, the placement channel 10 has a rectangular shape and is perpendicular to the body 1 in the width direction. The body 1 has a pair of conductive connecting parts. The pair of conductive connecting parts are located near the placement channel 10 and on one side of the placement channel 10 in the length direction of the body 1. The pair of conductive connecting parts are used to connect with a pair of conductive connecting feet 20 on the energy storage capacitor 2 and conduct electricity. After the pair of conductive connecting feet 20 on the energy storage capacitor 2 are connected with the pair of conductive connecting parts, the energy storage capacitor 2 can be placed in the placement channel 10. When the energy storage capacitor 2 is placed in the placement channel 10, the upper and lower sidewalls of the energy storage capacitor 2 in the vertical direction protrude from the placement channel 10.

[0086] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the placement channel 10 is perpendicular to the body 1 in the width direction. The wide-side bridges 13 and narrow-side bridges 14 formed on both sides of the placement channel 10 in the width direction are both elongated. This facilitates the support and confinement of the energy storage capacitor 2 placed in the placement channel 10 through the wide-side bridges 13 and narrow-side bridges 14, improving the reliability of confining the energy storage capacitor 2 in the placement channel 10. It also facilitates the arrangement of conductive lines on the wide-side bridges 13, reducing the difficulty of arranging conductive lines on the wide-side bridges 13. Furthermore, in this embodiment, by providing a channel close to the placement channel 1 on the body 1... The pair of conductive connecting parts provided at 0 facilitates the connection of the pair of conductive connecting feet 20 provided on the energy storage capacitor 2 to the pair of conductive connecting parts, which facilitates the installation of the energy storage capacitor 2 on the body 1 and allows the energy storage capacitor 2 to be placed in the placement slot 10. Furthermore, in this embodiment, the upper and lower sidewalls of the energy storage capacitor 2 in the vertical direction protrude from the placement slot 10, which is beneficial for the vertical center plane of the energy storage capacitor 2 to be close to the vertical center plane of the body 1. The dimensions of the upper and lower sidewalls of the energy storage capacitor 2 protruding from the placement slot 10 in the vertical direction are equal or equivalent, which is beneficial for reducing the size of the energy storage capacitor 2 protruding from the body 1.

[0087] In this embodiment, as Figures 1 to 4As shown, in this embodiment, the energy storage capacitor 2 has a cylindrical structure, and the width of the placement slot 10 in the horizontal direction is greater than the outer diameter of the energy storage capacitor 2. In addition, the placement slot 10 in this embodiment can also be designed as an approximately rectangular structure, and the structure of the placement slot 10 can also be designed into other shapes according to the shape of the energy storage capacitor 2.

[0088] Furthermore, such as Figures 1 to 4 As shown, the energy storage capacitor 2 in this embodiment has a cylindrical structure, meaning that the main body of the energy storage capacitor 2 has a cylindrical structure, and the energy storage capacitor 2 is also connected to a conductive connection pin 20; in addition, the energy storage capacitor 2 can also be designed into other shapes as needed.

[0089] In this embodiment, as Figure 1 and Figure 2 As shown, the body 1 is also provided with an avoidance recess 17. The avoidance recess 17 is recessed from the outside to the inside of the body 1 in the width direction of the body 1. The avoidance recess 17 is located on the side where the through groove 10 is placed in the length direction of the body 1. When the body 1 is injection molded and sealed, a channel structure that can pass through the hot glue is formed in the avoidance recess 17.

[0090] In this embodiment, as Figure 1 and Figure 2 As shown, in this embodiment, a pair of conductive connection parts specifically include a pair of metallized vias 15, which extend vertically out of the body 1; in this embodiment, a pair of conductive connection pins 20 on the energy storage capacitor 2 are soldered to the pair of metallized vias 15; in addition, the conductive connection parts in this embodiment can also adopt pads or other conductive connection structures.

[0091] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the body 1 in this embodiment is also provided with a relief recess 17. When the body 1 is injection molded and sealed, a channel structure that allows the hot adhesive to pass through is formed in the relief recess 17. The relief recess 17 adds a channel structure for the hot adhesive to pass through the body 1 placed in the injection cavity of the injection mold, which is conducive to the flow of the hot adhesive between the upper and lower sides of the body 1. It also improves the smoothness of the flow of the hot adhesive between the upper and lower sides of the body 1, which is conducive to reducing the injection pressure, thereby improving the stability of the injection molding and sealing quality of the body 1, and is conducive to forming a high-quality sealant on the outside of the body 1.

[0092] In this embodiment, during the injection molding and sealing process of the body 1, the body 1 is first placed in the injection cavity of the injection mold. The injection mold module is provided with an injection channel, which is located on the upper or lower side of the body 1. When hot adhesive is introduced into the injection cavity through the injection channel, the hot adhesive entering the injection cavity is mainly located on one side of the upper or lower side of the body 1, and then enters the other side of the upper or lower side of the body 1 through the gap between the body 1 and the inner wall of the injection cavity. In this embodiment, the avoidance recess 17 forms a channel structure that allows the hot adhesive to pass through. The hot adhesive can flow through the avoidance recess 17, which is beneficial for the hot adhesive to flow between the upper and lower sides of the body 1.

[0093] In this embodiment, as Figure 1 and Figure 2 As shown, multiple recessed grooves 17 are provided, which helps to further improve the smoothness of the flow of hot glue between the upper and lower sides of the body 1, thereby further reducing the injection pressure, thus further improving the stability of the injection molding sealing quality of the body 1, and helping to form an aesthetically pleasing sealing body on the outside of the body 1; furthermore, in this embodiment, two recessed grooves 17 are provided, and the two recessed grooves 17 are arranged back to back on the left and right sides of the body 1. The number of recessed grooves 17 can also be three, four, etc.

[0094] One embodiment of this utility model is as follows: Figures 1 to 4 As shown, the width of the wide-side bridge 13 is any value between 0.6mm and 1.6mm, and the width of the narrow-side bridge 14 is any value between 0.3mm and 0.8mm.

[0095] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the width of the wide-side bridge 13 is any value between 0.6mm and 1.6mm, which helps to ensure that the wide-side bridge 13 has a suitable width for arranging conductive lines and reduces the difficulty of arranging conductive lines on the wide-side bridge 13. Furthermore, the width of the narrow-side bridge 14 is any value between 0.3mm and 0.8mm, which helps to ensure that the narrow-side bridge 14 can provide reliable support for the outer wall of the energy storage capacitor 2 that is directly opposite it, thereby improving the reliability of confining the energy storage capacitor 2 within the placement slot 10. In addition, the suitable width dimensions of the wide-side bridge 13 and the narrow-side bridge 14 also help the placement slot 10 to have sufficient space in the width direction to accommodate the energy storage capacitor 2.

[0096] In this embodiment, given a fixed width of the main body 1, to ensure that the slot 10 can accommodate the energy storage capacitor 2 with a certain width, and given that the width of the energy storage capacitor 2 has a lower limit, if the energy storage capacitor 2 is too small, it is difficult to ensure that it can provide sufficient electrical energy, and it increases the manufacturing and design cost of the energy storage capacitor 2; if the width of the wide-side bridge 13 is equal to the width of the narrow-side bridge 14, then the width of the wide-side bridge 13 is insufficient to provide enough space for arranging conductive lines or increases the difficulty and cost of arranging conductive lines on the wide-side bridge 13; for example, if the width of the main body 1 is... If the width of the energy storage capacitor 2 is 3.0 mm and the width of the wide-side bridge 13 is 4.0 mm, then the sum of the widths of the wide-side bridge 13 and the narrow-side bridge 14 is 1.0 mm. When the width of both the wide-side bridge 13 and the narrow-side bridge 14 is 0.5 mm, it is considered that the width of the wide-side bridge 13 is insufficient to provide enough space for the arrangement of conductive lines or increases the difficulty and cost of arranging conductive lines on the wide-side bridge 13. It should be noted that the width values ​​of the body 1 in the above examples are only used to explain this application and are not used to limit the actual width of the body 1.

[0097] It should be noted that the narrow-side bridge 14 can provide support for the outer wall of the energy storage capacitor 2 that is directly opposite it. This can include direct support provided by the narrow-side bridge 14 directly abutting against the outer wall of the energy storage capacitor 2, or indirect support provided by the narrow-side bridge 14 to the outer wall of the energy storage capacitor 2, where a pad is provided between the narrow-side bridge 14 and the outer wall of the energy storage capacitor 2.

[0098] Another aspect of this application provides an electronic detonator control module, such as... Figure 3 and Figure 4 As shown, it includes:

[0099] The circuit board structure described above;

[0100] The energy storage capacitor 2 is placed in the placement slot 10. A pair of conductive connecting pins 20 on the energy storage capacitor 2 are connected to the body 1, and the energy storage capacitor 2 is electrically connected to the control circuit on the body 1 through a pair of conductive connecting pins 20.

[0101] The control chip is mounted on the main body 1 and is electrically connected to the control circuit.

[0102] Multiple electronic components are provided and mounted on the main body 1, and the electronic components are electrically connected to the control circuit.

[0104] Ignition element 4 is connected to the other end of the body 1 along its length and is electrically connected to the control circuit.

[0105] In this embodiment, as Figure 3 and Figure 4 As shown, the electronic detonator control module in this embodiment includes the aforementioned circuit board structure, which facilitates the placement of the energy storage capacitor 2 within the placement slot 10. Furthermore, when arranging the control circuit on the main body 1, the conductive lines constituting the control circuit can be arranged on the wide-side bridge 13. This facilitates the arrangement of conductive lines on the wide-side bridge 13 passing through one side of the placement slot 10 on the main body 1, and increases the distance between the conductive lines arranged on the wide-side bridge 13 on one side of the placement slot 10 and the energy storage capacitor 2 placed within the placement slot 10. This helps to prevent static electricity or other electrical energy flowing through the conductive lines arranged on the wide-side bridge 13 on one side of the placement slot 10 from adversely affecting the energy storage capacitor 2, improving the reliability and stability of the energy storage capacitor 2. It also reduces the difficulty of arranging conductive lines on one side of the placement slot 10. Further, the narrow-side bridge 14 is provided with narrow... The edge strength enhancement structure helps to strengthen the narrow side bridge 14, ensuring its strength. Furthermore, the width of the wide side bridge 13 is relatively wider than that of the narrow side bridge 14, allowing it to maintain its strength and preventing breakage of both bridges. The narrow side bridge 14 can also provide support for the outer wall of the energy storage capacitor 2, which is positioned opposite it. The energy storage capacitor 2 is confined between the wide and narrow side bridges 13 and 14 in the width direction, achieving proper support and positioning. This improves the accuracy of the energy storage capacitor 2's installation on the body 1, reduces its protrusion from the body 1, and enhances its reliability within the placement slot 10. Ultimately, this improves the quality and yield of the electronic detonator control module and enhances the blasting effect of the electronic detonator.

Furthermore, this embodiment has multiple electronic components. The selection of each electronic component can be appropriately made according to the functions required by the electronic detonator, referring to the prior art in the field.

[0111] In this embodiment, the electronic detonator control module needs to be injection molded and sealed before being assembled into the housing. Therefore, the electronic detonator control module in this embodiment may also include a sealing body wrapped around the outside of the electronic detonator control module. The sealing body is not shown in the illustration of the electronic detonator control module in this embodiment. The structure of the sealing body and the injection molding process can be referred to the existing electronic detonator control modules in the art, and will not be described in detail here.

[0112] One embodiment of this utility model is as follows: Figures 1 to 4 As shown, the control circuit includes:

[0113] The control circuit section 1 is arranged on the main body 1 and located on one side of the through slot 10 in the length direction of the main body 1;

[0114] The second control circuit is arranged on the main body 1 and is located on the other side of the placement slot 10 in the length direction of the main body 1.

[0115] The third control circuit is arranged on the wide-side bridge 13 and electrically connected between the first control circuit and the second control circuit.

[0116] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, by arranging control circuit section one on one side of the placement slot 10 of the main body 1, control circuit section two on the other side of the placement slot 10 of the main body 1, and control circuit section three on the wide-side bridge 13, it is beneficial to distribute the control circuits on the main body 1, avoiding excessively dense control circuit layout which could lead to leakage between conductive lines on the control circuits and affect the stability and reliability of the control circuits. It is also convenient to arrange electronic components at both ends of the main body 1, making full use of the usable area of ​​the main body 1 to arrange conductive lines and electronic components. Furthermore, it is beneficial to further reduce the size of the main body 1 while meeting the space requirements for circuit layout.

The distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer wall of the energy storage capacitor 2 facing it is any value between 0.2mm and 0.5mm. This helps to ensure that there is a suitable distance between the control circuit section three and the outer wall of the energy storage capacitor 2, thereby helping to avoid the adverse effects of static electricity or other electrical energy flowing through the control circuit section three on the energy storage capacitor 2, and improving the reliability and stability of the energy storage capacitor 2.

[0120] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer wall of the energy storage capacitor 2 in the width direction is 0.3mm.

Furthermore, when the distance between the control circuit section three and the outer wall of the energy storage capacitor 2 is less than 0.2mm, the anti-static capability of the energy storage capacitor 2 is less than 10KV, and the energy storage capacitor 2 is easily broken down under the action of electrostatic discharge, resulting in damage or even failure.

The increased width facilitates the arrangement of the second circuit control unit three within the second circuit arrangement area three. Furthermore, it increases the distance between the first and second circuit control units three and the energy storage capacitor 2 placed in the placement slot 10, thereby helping to prevent static electricity or other electrical energy flowing through the first and second circuit control units three from adversely affecting the energy storage capacitor 2 and improving the reliability and stability of the energy storage capacitor 2.

[0135] In this embodiment, the front circuit and the back circuit are electrically connected to form a control circuit, which facilitates the arrangement of electronic components on the two sides of the body 1, making full use of the available area of ​​the body 1 to arrange conductive lines and electronic components, and also helps to further reduce the size of the body 1 while meeting the space requirements for circuit arrangement.

[0136] In this embodiment, as Figure 3 and Figure 4 As shown, the front end of the main body 1 is component placement end 11, and the rear end of the main body 1 is component placement end 2 12. In this embodiment, the first control circuit part 1 is arranged on the upper side of component placement end 11, the second control circuit part 1 is arranged on the lower side of component placement end 11, the first control circuit part 2 is arranged on the upper side of component placement end 2 12, the second control circuit part 2 is arranged on the lower side of component placement end 2 12, the first circuit control part 3 is arranged on the upper side of the wide-side bridge 13, and the second circuit control part 3 is arranged on the lower side of the wide-side bridge 13. Furthermore, the specific structure of the control circuit is not illustrated in this embodiment, and the specific structure and wiring method of the control circuit can be flexibly adjusted according to the functional requirements of the electronic detonator control module. The specific structure and wiring method of the control circuit can also be various, which will not be elaborated here.

[0137] One embodiment of this application, such as Figures 1 to 4 As shown, the control circuit section three is arranged along the length direction of the wide side bridge 13, and the distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer side wall of the energy storage capacitor 2 facing it is any value between 0.2mm and 0.5mm.

[0138] In this embodiment, as Figures 1 to 4As shown, in this embodiment, the control circuit section three is arranged along the length direction of the wide-side bridge 13, which helps to increase the distance between the control circuit section three and the outer wall of the energy storage capacitor 2 directly opposite it. Furthermore, the distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer wall of the energy storage capacitor 2 in the width direction is any value between 0.2mm and 0.5mm, which helps to ensure that there is a suitable distance between the control circuit section three and the outer wall of the energy storage capacitor 2, thereby helping to avoid the adverse effects of static electricity or other electrical energy flowing through the control circuit section three on the energy storage capacitor 2, and improving the reliability and stability of the energy storage capacitor 2.

[0139] Furthermore, in this embodiment, the distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer wall of the energy storage capacitor 2 in the width direction is 0.3mm. The distance between the side of the control circuit section three facing the energy storage capacitor 2 and the outer wall of the energy storage capacitor 2 can also be designed as any value between 0.2mm and 0.5mm as needed, and can better ensure that the anti-static capability of the energy storage capacitor 2 reaches more than 10KV, ensuring that the energy storage capacitor 2 is not broken down by 10KV electrostatic discharge, thus meeting the electrostatic protection requirements of the electronic detonator. Furthermore, when the distance between the control circuit section three and the outer wall of the energy storage capacitor 2 is less than 0.2mm, the anti-static capability of the energy storage capacitor 2 is less than 10KV, and the energy storage capacitor 2 is easily broken down under the action of electrostatic discharge, resulting in damage or even failure.

[0140] One embodiment of this utility model is as follows: Figures 1 to 4 As shown, the wide-side bridge 13 has a gap between its width direction and the outer wall of the energy storage capacitor 2, which is directly opposite to it, forming a gap. The size of the gap is any value between 0.1mm and 0.3mm. After the body 1 and the energy storage capacitor 2 are injection molded and sealed, a sealing layer is formed in the gap.

[0141] The narrow-side bridge 14 has a gap in the width direction between itself and the outer wall of the energy storage capacitor 2 that is directly opposite it, forming a gap two. The size of the gap two is any value between 0.1mm and 0.3mm. After the body 1 and the energy storage capacitor 2 are injection molded and sealed, a sealing layer two is formed in the gap two, and the outer wall of the energy storage capacitor 2 facing the narrow-side bridge 14 is supported by the sealing layer two and the narrow-side bridge 14.

[0142] In this embodiment, as Figures 1 to 4As shown, in this embodiment, the size of gap one is any value between 0.1mm and 0.3mm. The size of gap one is suitable. After the body 1 and the energy storage capacitor 2 are injection molded and sealed, a sealing layer one is formed in gap one. This is beneficial for the sealing layer one formed after injection molding to have a suitable thickness. It is also beneficial for the sealing layer one to block the static electricity or other electrical energy flowing through the conductive lines arranged on the wide side bridge 13 on one side of the placement slot 10 through the block, so as to avoid the static electricity or other electrical energy flowing through the conductive lines arranged on the wide side bridge 13 on one side of the placement slot 10 from having an adverse effect on the energy storage capacitor 2, thereby improving the reliability and stability of the energy storage capacitor 2. Furthermore, in this embodiment, the size of gap two is any value between 0.1mm and 0.3mm. The size of gap two is suitable. After the body 1 and the energy storage capacitor 2 are injection molded and sealed, a sealing layer two is formed in gap two. This is beneficial for the sealing layer two formed after injection molding to have a suitable thickness, and it is also beneficial for the sealing layer two and the narrow side bridge 14 to reliably support the outer wall of the energy storage capacitor 2 facing the narrow side bridge 14.

[0143] In this embodiment, a sealing layer is formed after injection molding and sealing within a gap of any value between 0.1mm and 0.3mm. A sealing layer of any value between 0.1mm and 0.3mm is formed on the outer wall of the energy storage capacitor 2. The sealing layer covers the energy storage capacitor 2, and the outer wall of the energy storage capacitor 2 and the wide-side bridge 13 can be blocked by the sealing layer from the static electricity or other electrical energy flowing through the conductive lines arranged on one side of the placement channel 10 of the wide-side bridge 13. This further improves the protection capability of the energy storage capacitor 2 against static electricity or other electrical energy flowing through the conductive lines arranged on one side of the placement channel 10 of the wide-side bridge 13.

[0144] In this embodiment, as Figure 3 and Figure 4 As shown, the energy storage capacitor 2 in this embodiment has a cylindrical structure. The gap 1 specifically refers to the distance between the point where the plane of the energy storage capacitor 2 and the center plane of the body 1 in the vertical direction intersects with the left arc line of the energy storage capacitor 2 and the left side wall of the narrow side bridge 14 after the energy storage capacitor 2 is placed in the placement slot 10.

[0145] It should be noted that after the electronic detonator control module is injection molded, the encapsulated body formed by the injection molding will encapsulate the entire energy storage capacitor 2, and the encapsulated body will also encapsulate the electronic components installed on the main body 1, with the wiring terminal 3 and ignition element 4 exposed on the outside of the encapsulated body.

[0146] One embodiment of this utility model is as follows: Figure 3 and Figure 4As shown, the peripheral sidewalls of the energy storage capacitor 2 in the width direction abut against the inner sidewalls of the wide side bridge 13 and the narrow side bridge 14 respectively, and the energy storage capacitor 2 can be lifted and positioned by the wide side bridge 13 and the narrow side bridge 14 in the width direction, thus being confined between the wide side bridge 13 and the narrow side bridge 14.

[0147] In this embodiment, as Figure 3 and Figure 4 As shown, in this embodiment, the peripheral sidewalls of the energy storage capacitor 2 in the width direction abut against the inner sidewalls of the wide side bridge 13 and the narrow side bridge 14, which is beneficial for the energy storage capacitor 2 to be lifted and positioned by the wide side bridge 13 and the narrow side bridge 14 in the width direction. This is beneficial for the energy storage capacitor 2 to be lifted and positioned by the wide side bridge 13 and the narrow side bridge 14 before it is fixed in the placement slot, which makes it easier to accurately install the energy storage capacitor 2 on the body 1, especially when the energy storage capacitor 2 is attached to the body 1 in a patch-like direction.

[0148] It should be noted that, in this embodiment, when the peripheral sidewalls of the energy storage capacitor 2 in the width direction do not abut against the inner sidewalls of the wide-side bridge 13 and the narrow-side bridge 14, a positioning tool can be used to assist in lifting and positioning the energy storage capacitor 2 when installing it onto the body 1. However, when the peripheral sidewalls of the energy storage capacitor 2 in the width direction abut against the inner sidewalls of the wide-side bridge 13 and the narrow-side bridge 14, the positioning tool can be omitted when installing the energy storage capacitor 2 onto the body 1; the wide-side bridge 13 and the narrow-side bridge 14 can be used to lift and position the energy storage capacitor 2. It should be noted that there can be various positioning tools in this embodiment, and existing technologies can also be referenced; these will not be described in detail here.

[0151] The aforementioned electronic detonator control module is installed inside the mounting cavity.

[0152] In this embodiment, the electronic detonator includes the aforementioned electronic detonator control module. This helps to prevent static electricity or other electrical energy flowing through the conductive lines on the wide-side bridge 13 arranged on one side of the placement slot 10 from adversely affecting the energy storage capacitor 2. It also helps to improve the strength of the wide-side bridge 13 and the narrow-side bridge 14, thereby improving the reliability and stability of the energy storage capacitor 2. In addition, it helps to ensure that the overall width of the electronic detonator control module is within a suitable size range, so that the overall width of the electronic detonator control module matches the size of the mounting cavity in the housing. This facilitates the smooth installation of the electronic detonator control module into the mounting cavity, thereby improving the assembly efficiency of the electronic detonator control module and the quality of the electronic detonator.

[0153] It should be noted that, within a suitable size range, the "overall width size" of the electronic detonator control module in this embodiment refers to the size in the width direction of the electronic detonator control module.
