Description

Technical Field

[0001] This utility model relates to the field of pyrotechnics technology, and in particular to a PCB board structure, board assembly, control module, and electronic detonator for an electronic detonator control module. Background Technology

[0002] Currently, electronic detonators are widely used in tunneling, hazard removal blasting, demolition blasting, rock separation, and open-pit mine blasting. Existing electronic detonators mainly consist of lead wires, plastic plugs, control modules, basic explosives, and basic casings. The control module is the detonation control part of the electronic detonator, and its stability directly affects the stability of the electronic detonator. The control module mainly includes electronic components such as an integrated control chip, igniter, and energy storage capacitor mounted on a circuit board. In addition, during the production process, the control module needs to be injection molded to protect the electronic components mounted on the circuit board, providing moisture and dust protection. Furthermore, the injection-molded control module is assembled into a protective casing, which then protects the injection-molded control module.

[0003] Furthermore, in existing technologies, to achieve injection molding and sealing of the control module, the control module is placed into the injection cavity of an injection mold, and then injection molded into shape using an injection molding and sealing process. Further, in existing technologies, the injection cavity has a sprue for injecting hot glue on one side of the control module's width. After the control module is injection molded and sealed, sprue material forms at the sprue. Since control modules are often injection molded and sealed in batches, the spacing between adjacent control modules is small, and the sprue material at the sprue can only be removed manually, which is prone to residue and has high removal costs. The spacing between adjacent control modules is mainly determined by the spacing between the PCB boards within the adjacent control modules. The PCB board structure affects the protrusion size of the sprue material and the method of sprue material removal. Therefore, there is an urgent need for a PCB board structure that facilitates the removal of sprue material. Summary of the Invention

[0004] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a PCB board structure for an electronic detonator control module that facilitates the removal of glue inlet material; in addition, it also provides a board assembly for an electronic detonator control module, a control module for an electronic detonator control module, and an electronic detonator.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] According to one aspect of this application, a PCB board structure for an electronic detonator control module is provided, comprising:

[0007] The body is a long plate-shaped structure. At its first end along its length is a mounting portion one for mounting terminals, and at its second end along its length is a mounting portion two for mounting an igniter. Between the first and second ends along its length is an electronic component mounting portion for mounting electronic components. The body has a concave hot glue injection channel along its width. When the body is placed in the injection cavity of an injection mold for injection molding and sealing, a hot glue injection channel is formed at the hot glue injection channel, allowing the hot glue used for injection molding and sealing to be injected into the injection cavity.

[0008] The beneficial effects of this utility model are as follows: In this embodiment, the body has a concave hot colloid injection channel in the width direction. When the body is placed in the injection cavity of the injection mold for injection sealing, a hot colloid injection channel is formed at the hot colloid injection channel on the body. This facilitates setting the inlet directly opposite the hot colloid injection channel, and increases the depth of the inlet in the width direction of the body, thereby increasing the thickness of the sprue material formed after injection sealing. This makes it easier to remove the sprue material by punching with a punching tool, thus facilitating the removal of the sprue material and reducing the difficulty of removing it. Furthermore, the concave hot colloid injection channel in the width direction of the body ensures that the hot colloid injection channel still has a suitable colloid thickness after the sprue material is punched and removed.

[0009] 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.

[0010] According to one embodiment of the present invention, the two ends of the body in the width direction are respectively provided with the thermocolloid injection flow port facing each other.

[0011] In this embodiment, the two ends of the main body in the width direction are respectively provided with hot glue injection passages facing each other. When the control module containing the PCB board structure in this embodiment is injection molded in batches, it is beneficial for the hot glue injection passages on the main body of two adjacent control modules to be facing each other, thereby further increasing the distance between the hot glue injection passages on the two adjacent main bodies, and further increasing the thickness of the sprue material formed after injection molding. This makes it easier to use a punching tool to punch and remove the sprue material, thereby facilitating the removal of the sprue material, avoiding residual sprue, and further reducing the difficulty of removing the sprue material.

[0012] According to one embodiment of the present invention, the thermocolloid injection ports provided at both ends of the body in the width direction are symmetrically arranged with respect to the width center plane of the body in the width direction.

[0013] In this embodiment, the hot glue injection port on the main body is symmetrically arranged with respect to the width center plane of the main body. When the main body is injected and sealed into the injection cavity placed in the injection mold, it is beneficial for the hot glue to flow symmetrically into the injection cavity, reducing the impact pressure of the hot glue on the injection mold and improving the smoothness of the hot glue flowing into the injection cavity.

[0014] According to one embodiment of the present invention, a first end of the body in the length direction is provided with a connecting portion for connecting the wiring terminal, and the first mounting portion includes the connecting portion; a second end of the body in the length direction is provided with a mounting portion for mounting the igniter, and the second mounting portion includes the mounting portion.

[0015] In this embodiment, the first end of the body in the length direction is provided with a connecting part for connecting the wiring terminal, which facilitates the connection of the wiring terminal to the first end of the body in the length direction and helps to improve the stability of the wiring terminal connection to the body; furthermore, the second end of the body in the length direction is provided with a mounting part for mounting the igniter, which facilitates the mounting of the igniter to the second end of the body in the length direction using a surface mount process.

[0016] According to one embodiment of the present invention, the width of the first end of the body in the length direction is equal to the width of the electronic component mounting part, and the width of the second end of the body in the length direction is smaller than the width of the electronic component mounting part.

[0017] In this embodiment, the width of the second end in the length direction of the main body is smaller than the width of the electronic component mounting part. This is beneficial for subsequently using a propellant head protective sleeve to cover the outer periphery of the igniter mounted on the second end in the length direction of the main body to protect the igniter. Furthermore, the width of the first end in the length direction of the main body and the width of the electronic component mounting part are equal, which helps to ensure the strength of the first end in the length direction of the main body and the electronic component mounting part, and facilitates the improvement of the stability of the terminal block connection on the first end in the length direction of the main body, as well as the stability of the electronic components mounted on the electronic component mounting part.

[0018] According to one embodiment of the present invention, the second end of the hot colloid injection passage near the length direction of the body is disposed in the width direction of the electronic component mounting part of the body. The sum of the length dimensions of the first end of the body in the length direction and the electronic component mounting part is L1, and the length dimension of the second end of the body in the length direction is L2, wherein L1=N*L2, and N is any value from 2 to 5.

[0019] In this embodiment, the sum of the lengths of the first end of the body in the length direction and the electronic component mounting part is L1, and the length of the second end of the body in the length direction is L2, where L1 = N * L2, and N is any value from 2 to 5, so that the total length of the first end of the body in the length direction and the electronic component mounting part is suitable, so that sufficient space is provided on the electronic component mounting part for arranging electronic components.

[0020] According to another aspect of this application, a board assembly for an electronic detonator control module is provided, comprising a board body, the board body including:

[0024] A left longitudinal connecting edge is provided on the left side of the plate along the longitudinal direction. The left longitudinal connecting edge is perpendicularly connected to the front transverse connecting edge, the multiple middle transverse connecting edges, and the rear transverse connecting edge.

[0025] Multiple intermediate longitudinal connecting edges are provided. These intermediate longitudinal connecting edges are arranged in the middle of the plate body along the longitudinal direction and parallel to the left longitudinal connecting edge. The intermediate longitudinal connecting edges are perpendicularly connected between the front transverse connecting edge and the intermediate transverse connecting edge, between two adjacent intermediate transverse connecting edges, and between the front transverse connecting edge and the intermediate transverse connecting edge.

[0026] A right longitudinal connecting edge is provided on the right side of the plate body along the longitudinal direction and parallel to the middle longitudinal connecting edge. The right longitudinal connecting edge is perpendicularly connected to the front transverse connecting edge, multiple middle transverse connecting edges, and rear transverse connecting edge.

[0027] The aforementioned PCB board structure for the electronic detonator control module includes multiple bodies, each of which is vertically connected between the front lateral connecting edge and the adjacent and opposite middle lateral connecting edge, between two adjacent middle lateral connecting edges, and between the rear lateral connecting edge and the adjacent and opposite middle lateral connecting edge, with the multiple bodies spaced apart in the lateral direction.

[0028] The board assembly for the electronic detonator control module in this embodiment includes multiple PCB board structures as described above. This facilitates the arrangement of electronic components on multiple bodies to obtain multiple control modules. It is convenient to place the obtained multiple control modules into the injection cavity of the injection mold, and then injection mold the control modules placed in the injection cavity through the injection molding and sealing process. When the multiple bodies placed in the multiple injection cavities of the injection mold are injection molded and sealed, it is beneficial to form hot glue injection channels at the hot glue injection flow port. It is also beneficial to set the glue inlet directly opposite the hot glue injection flow port. The depth dimension of the glue inlet is increased in the width direction of the body, and the thickness of the glue gate material formed after injection molding and sealing is increased. This makes it easier to use a punching tool to punch and remove the formed glue gate material, thereby facilitating the removal of the glue gate material and reducing the difficulty of removing the glue gate material. In addition, it is convenient to realize batch sealing and improve the sealing speed.

[0029] According to one embodiment of the present invention, the board assembly for the electronic detonator control module further includes:

[0030] A transverse pre-break structure is provided in multiple places. The transverse pre-break structure is set opposite to the end face of the first end in the length direction of the body. The transverse pre-break structure passes through the left longitudinal connecting edge, the middle longitudinal connecting edge, the right longitudinal connecting edge and the end face of the first end in the length direction of the body in the transverse direction.

[0031] The second transverse pre-break structure is provided in multiple ways. The second transverse pre-break structure is set opposite to the end face of the second end in the length direction of the body. The second transverse pre-break structure passes through the left longitudinal connecting edge, the middle longitudinal connecting edge, the right longitudinal connecting edge and the end face of the second end in the length direction of the body in the transverse direction.

[0032] In this embodiment, by providing a first transverse pre-break structure and a second transverse pre-break structure, it is convenient to break or mechanically separate the components along the first transverse pre-break structure and the second transverse pre-break structure respectively in subsequent processing steps, thereby obtaining an electronic detonator control module including the main body, which provides convenience for subsequent processing steps.

[0033] According to one embodiment of the present invention, the board assembly for the electronic detonator control module further includes:

[0034] The process edge is connected to the front side of the front transverse connecting edge and / or the rear side of the rear transverse connecting edge. The process edge is used to provide clamping support. A transverse pre-break structure is provided between the front transverse connecting edge and / or the rear transverse connecting edge and the process edge.

[0035] In this embodiment, when a process edge is connected to the front side of the front side or the rear side of the rear side of the front lateral connecting edge, it is beneficial to match the reflow carrier with the process edge when mounting electronic components onto the body using the surface mount process. This facilitates the improvement of the reliability of the reflow carrier in clamping and supporting the board assembly for the electronic detonator control module. Furthermore, when a process edge is connected to the front side of the front side and the rear side of the rear lateral connecting edge, it is beneficial to further improve the applicability of the board assembly for the electronic detonator control module to the reflow carrier.

[0036] According to another aspect of this application, a control module for an electronic detonator control module is provided, comprising:

[0037] The PCB board structure for the electronic detonator control module described above includes a control circuit on the main body.

[0038] An energy storage capacitor is mounted on the main body and electrically connected to the control circuit.

[0039] A control chip is mounted on the electronic component mounting part of the main body, and the control chip is electrically connected to the control circuit.

[0040] The electronic components are provided in multiple portions and are respectively mounted on the electronic component mounting portion of the main body, and the electronic components are electrically connected to the control circuit;

[0041] The wiring terminal is connected to the first end in the length direction of the body and is electrically connected to the control circuit.

[0042] The igniter is connected to the second end of the body along its length and is electrically connected to the control circuit.

[0043] The control module for the electronic detonator control module in this embodiment includes the PCB board structure for the electronic detonator control module described above, which facilitates the production of the control module through surface mount technology and reduces the production cost of the control module.

[0044] According to one embodiment of the present invention, the control module for the electronic detonator control module further includes:

[0045] The encapsulant is injection molded by an injection molding process. The encapsulant covers the outer periphery of the body, the energy storage capacitor, the control chip, and the plurality of electronic components. The encapsulant covers the portion of the terminal block near the first end of the body in the length direction. The portion of the terminal block protruding outward from the first end of the body in the length direction is exposed outside the encapsulant. The igniter is exposed outside the encapsulant.

[0046] The sealant forms a recessed groove that is concave from the outside to the inside at the location of the hot glue injection port.

[0047] In this embodiment, when the control module is placed in the injection mold for injection molding and sealing, multiple bodies are located in multiple injection cavities. The hot glue injection flow port on the body forms a hot glue injection flow channel, which is beneficial for setting the glue inlet directly opposite the hot glue injection flow port. The depth dimension of the glue inlet is increased in the width direction of the body, thereby increasing the thickness of the glue gate material formed after injection molding and sealing. This facilitates the removal of the formed glue gate material by punching with a punching tool, which is beneficial for removing the glue gate material and forming a recessed groove from the outside to the inside. This helps to prevent the glue gate from remaining protruding width dimension and affecting the positioning accuracy of subsequent processing steps of the control module.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] One aspect of this application provides a PCB board structure for an electronic detonator control module, such as... Figures 1 to 6 As shown, it includes:

[0063] The body 18 is a long plate-shaped structure. The first end of the body 18 in the length direction is provided with a mounting part 1 for mounting the terminal block 182, and the second end of the body 18 in the length direction is provided with a mounting part 2 for mounting the igniter 183. The area between the first end and the second end of the body 18 in the length direction is an electronic component mounting part for mounting electronic components. The body 18 in the width direction is provided with a hot glue injection passage 181 that is recessed from the outside to the inside. When the body 18 is placed in the injection cavity of the injection mold for injection sealing, a hot glue injection passage 181 is formed at the hot glue injection passage 181, and the hot glue used for injection sealing can be injected into the injection cavity through the hot glue injection passage.

[0064] In this embodiment, as Figures 1 to 6As shown, in this embodiment, the body 18 has a concave hot glue injection passage 181 in the width direction. When the body 18 is placed in the injection cavity of the injection mold for injection molding and sealing, a hot glue injection passage 181 is formed on the body 18, which is beneficial to align the inlet with the hot glue injection passage 181. The depth of the inlet is increased in the width direction of the body 18, thereby increasing the thickness of the sprue material formed after injection molding and sealing. This makes it easier to remove the sprue material by punching with a punching tool, which is beneficial for removing the sprue material and also reduces the difficulty of removing the sprue material. Furthermore, the concave hot glue injection passage 181 in the width direction of the body 18 is beneficial to ensure that the hot glue injection passage 181 still has a suitable glue thickness after the sprue material is punched and removed.

[0065] In this embodiment, as Figure 1 and Figure 6 As shown, the body 18 has a long plate-like structure, specifically meaning that the length of the body 18 is greater than its width. Furthermore, in this embodiment, the hot glue injection flow port 181 has an arc-shaped concave structure. Correspondingly, after the punching tool in this embodiment punches and removes the formed glue inlet material, the electronic detonator control module obtained in production forms a concave groove 20 from the outside to the inside at the position of the hot glue injection flow port 181. The concave groove 20 has an arc-shaped concave groove structure.

[0066] One embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 6 As shown, the two ends of the body 18 in the width direction are respectively provided with hot colloid injection flow ports 181 facing each other.

[0067] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the two ends of the body 18 in the width direction are respectively provided with hot glue injection passages 181 facing each other. When the control module containing the PCB board structure in this embodiment is injection molded in batches, it is beneficial that the hot glue injection passages 181 on the body 18 of two adjacent control modules are facing each other, thereby further increasing the distance between the hot glue injection passages 181 on the two adjacent body 18, and further increasing the thickness of the sprue material formed after injection molding. This makes it easier to use a punching tool to punch and remove the sprue material, thereby facilitating the removal of the sprue material, avoiding residual sprue, and further reducing the difficulty of removing the sprue material.

[0068] One embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 6 As shown, the thermocolloid injection ports 181 provided at both ends of the body 18 in the width direction are symmetrically arranged with respect to the width center plane of the body 18 in the width direction.

[0069] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the hot glue injection port 181 on the body 18 is symmetrically arranged with respect to the width center plane of the body 18. When the body 18 is injected and sealed into the injection cavity placed in the injection mold, it is beneficial for the hot glue to flow symmetrically into the injection cavity, reducing the impact pressure of the hot glue on the injection mold and improving the smoothness of the hot glue flowing into the injection cavity.

[0070] One embodiment of this utility model is as follows: Figures 1 to 6 As shown, the first end of the body 18 in the length direction is provided with a connecting part for connecting the terminal block 182, and the first mounting part includes the connecting part; the second end of the body 18 in the length direction is provided with a mounting part for mounting the igniter 183, and the second mounting part includes the mounting part.

[0071] In this embodiment, as Figures 1 to 6 As shown, in this embodiment, the first end of the body 18 in the length direction is provided with a connecting part for connecting the terminal block 182, which facilitates connecting the terminal block 182 to the first end of the body 18 in the length direction and helps to improve the stability of the terminal block 182 connected to the body 18; furthermore, the second end of the body 18 in the length direction is provided with a mounting part for mounting the igniter 183, which facilitates mounting the igniter 183 to the second end of the body 18 in the length direction using a surface mount process.

[0072] One embodiment of this utility model is as follows: Figure 1 and Figure 6 As shown, the width of the first end of the body 18 in the length direction is equal to the width of the electronic component mounting part, and the width of the second end of the body 18 in the length direction is smaller than the width of the electronic component mounting part.

[0073] In this embodiment, as Figure 1 and Figure 6As shown, in this embodiment, the width of the second end of the body 18 in the length direction is smaller than the width of the electronic component mounting part. This is beneficial for subsequently using a propellant head protective sleeve to cover the outer periphery of the igniter 183 mounted on the second end of the body 18 in the length direction to protect the igniter 183. Furthermore, the width of the first end of the body 18 in the length direction and the width of the electronic component mounting part are equal, which helps to ensure the strength of the first end of the body 18 in the length direction and the electronic component mounting part. This facilitates improving the stability of the terminal block 182 connected to the first end of the body 18 in the length direction and also improves the stability of the electronic components mounted on the electronic component mounting part.

[0074] One embodiment of this utility model is as follows: Figure 1 and Figure 6 As shown, the second end of the hot colloid injection port 181 near the length direction of the body 18 is located in the width direction of the electronic component mounting part of the body 18. The sum of the length dimensions of the first end of the body 18 in the length direction and the electronic component mounting part is L1, and the length dimension of the second end of the body 18 in the length direction is L2, where L1=N*L2, and N is any value in 2-5.

[0075] In this embodiment, as Figure 1 and Figure 6 As shown, in this embodiment, the sum of the lengths of the first end of the body 18 in the length direction and the electronic component mounting part is L1, and the length of the second end of the body 18 in the length direction is L2, where L1=N*L2, and N is any value from 2 to 5, so that the total length of the first end of the body 18 in the length direction and the electronic component mounting part is suitable, so that sufficient space is provided on the electronic component mounting part for arranging electronic components.

[0076] Another aspect of this application provides a board assembly for an electronic detonator control module, such as... Figure 1 and Figure 2 As shown, it includes plate 1, which includes:

[0077] The front transverse connecting edge 10 is set on the front side of the plate 1 in the transverse direction;

[0079] The rear transverse connecting edge 12 is provided on the rear side of the plate 1 along the transverse direction and parallel to the front transverse connecting edge 10.

[0080] The left longitudinal connecting edge 13 is set on the left side of the plate 1 along the longitudinal direction. The left longitudinal connecting edge 13 is perpendicularly connected to the front transverse connecting edge 10, multiple middle transverse connecting edges 11 and the rear transverse connecting edge 12.

[0081] Multiple intermediate longitudinal connecting edges 14 are provided. These multiple intermediate longitudinal connecting edges 14 are arranged in the middle of the plate body 1 along the longitudinal direction and parallel to the left longitudinal connecting edge 13.

[0084] In this embodiment, as Figure 1 and Figure 2 As shown, the board assembly for the electronic detonator control module in this embodiment includes multiple PCB board structures as described above for the electronic detonator control module. This facilitates the arrangement of electronic components on multiple bodies 18 to obtain multiple control modules. It is convenient to place the obtained multiple control modules into the injection cavity of the injection mold, and then injection mold the control modules placed in the injection cavity through the injection molding and sealing process. When the multiple bodies 18 placed in the multiple injection cavities of the injection mold are injection molded and sealed, it is beneficial to form hot glue injection flow channels at the hot glue injection flow port 181. It is also beneficial to set the glue inlet directly opposite the hot glue injection flow port 181. The depth dimension of the glue inlet is increased in the width direction of the body 18, which increases the thickness of the glue gate material formed after injection molding and sealing. This makes it easier to use a punching tool to punch and remove the formed glue gate material, thereby facilitating the removal of the glue gate material and reducing the difficulty of removing the glue gate material. In addition, it is convenient to achieve batch sealing and improve the sealing speed.

The first transverse pre-cut structure is set directly opposite the end face of the first end in the length direction of the body 18. The first transverse pre-cut structure passes through the left longitudinal connecting edge 13, the middle longitudinal connecting edge 14, the right longitudinal connecting edge 15 and the end face of the first end in the length direction of the body 18 in the transverse direction.

[0089] The second transverse pre-cut structure is provided in multiple ways.

In this embodiment, the ninth brittle line 19 is a brittle line with a groove structure. It should be noted that the brittle line in this embodiment can be formed by cutting the material using tools such as knives or lasers. The formation of the brittle line can refer to the prior art in this field.

[0095] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the board assembly for the electronic detonator control module also includes:

[0096] The front side of the front transverse connecting edge 10 and the rear side of the rear transverse connecting edge 12 are connected to the process edge. The process edge is used to provide clamping support. A transverse pre-break structure is provided between the front transverse connecting edge 10 and the rear transverse connecting edge 12 and the process edge.

[0097] Furthermore, in this embodiment, a process edge may be connected only to the front side of the front side of the horizontal connecting edge 10 or the rear side of the horizontal connecting edge 12, and a horizontal pre-break structure three is provided between the front side of the horizontal connecting edge 10 or the rear side of the horizontal connecting edge 12 and the process edge; in this embodiment, the board assembly for the electronic detonator control module with a process edge connected only to the front side of the front side of the horizontal connecting edge 10 or the rear side of the horizontal connecting edge 12 is not illustrated.

[0098] In this embodiment, as Figure 1 and Figure 2 As shown, in this embodiment, when a process edge is connected to the front side of the front side of the transverse connecting edge 10 or the rear side of the transverse connecting edge 12, it is beneficial to match the reflow carrier with the process edge when mounting electronic components onto the body 18 by surface mount technology, thereby improving the reliability of the reflow carrier in clamping and supporting the board assembly for the electronic detonator control module. Furthermore, when a process edge is connected to the front side of the front side of the transverse connecting edge 10 and the rear side of the transverse connecting edge 12, it is beneficial to further improve the applicability of the board assembly for the electronic detonator control module to the reflow carrier.

[0101] In another aspect, this application provides a control module for an electronic detonator control module, such as... Figure 2 and Figure 3As shown, it includes:

[0102] The PCB board structure for the electronic detonator control module described above has a control circuit on the main body 18.

[0103] The energy storage capacitor is mounted on the main body 18 and electrically connected to the control circuit.

[0104] The control chip is mounted on the electronic component mounting section of the main body 18, and the control chip is electrically connected to the control circuit.

[0105] The electronic components are provided in multiple parts and are respectively mounted on the electronic component mounting part of the body 18. The electronic components are electrically connected to the control circuit.

[0106] Terminal 182 is connected to the first end of the body 18 along its length and is electrically connected to the control circuit.

[0107] Igniter 183 is connected to the second end of the body 18 along its length and is electrically connected to the control circuit.

[0108] In this embodiment, as Figure 2 and Figure 3 As shown, the control module for the electronic detonator control module in this embodiment includes the PCB board structure for the electronic detonator control module described above, which facilitates the production of the control module through surface mount technology and reduces the production cost of the control module.

[0109] In this embodiment, as Figure 2 and Figure 3 As shown, energy storage capacitors, control chips, wiring terminals 182, igniters 183, and multiple electronic components are respectively mounted on the body 18 of the board 1 used for electronic detonator control modules to obtain the control module in this embodiment. Furthermore, the control module in this embodiment has three rows of bodies 18, with twenty bodies 18 in each row, enabling the production of sixty electronic detonator control modules in a single batch. Further, in order to reduce the length of the injection mold and to arrange multiple bodies 18 along the length direction while maintaining a fixed length, it is necessary to reduce the lateral spacing between adjacent bodies 18 to arrange twenty bodies 18 on one row of a single board 1. For example, the lateral spacing between two adjacent bodies 18 on the board 1 is 2.5 mm.

[0110] In this embodiment, as Figures 3 to 5As shown, the terminal block 182 in this embodiment includes two conductive connecting leads 1821 and a connecting block 1822. The rear ends of the two conductive connecting leads 1821 are respectively installed in two conductive connecting holes 184, and the rear ends of the conductive connecting leads 1821 are encapsulated on the body 18 by the connecting block 1822. In this embodiment, the connecting block 1822 is a sealing block. The connecting block 1822 is formed by injection molding. The forming of the connecting block 1822 is not the focus of this application, and the forming of the connecting block 1822 can also refer to the prior art in this field, and will not be described in detail here.

[0111] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the igniter 183 is mounted on the rear end of the body 18 using a surface mount technology (SMT) process. The specific process of mounting the igniter 183 on the rear end of the body 18 using the SMT process can be referred to the prior art in this field. Furthermore, the structure and working principle of the igniter 183 can also be referred to the prior art in this field, and will not be described in detail here. In addition, the surface mount technology in this embodiment is specifically the STM surface mount technology.

[0112] In this embodiment, the specific process of mounting the energy storage capacitor, control chip, and multiple electronic components onto the body 18 using a surface mount technology can be referred to existing technologies in the art. It should be noted that the electronic components in this embodiment can be selected based on existing technologies to meet the detonation control and functional requirements of the electronic detonator. The arrangement and selection of the energy storage capacitor, control chip, and multiple electronic components are not the focus of this application and will not be elaborated upon here. Furthermore, the control circuit arranged on the body 18 is not illustrated in this embodiment. The structure of the control circuit can have various forms and can be designed as needed, and will not be elaborated upon here.

[0113] One embodiment of this utility model is as follows: Figure 4 and Figure 5 As shown, the control module for the electronic detonator control module also includes:

[0114] The encapsulant 2 is injection molded by an injection molding process. The encapsulant 2 covers the outer periphery of the body 18, the energy storage capacitor, the control chip and multiple electronic components. The encapsulant 2 covers the portion of the terminal 182 near the first end of the body 18 in the length direction. The portion of the terminal 182 that protrudes outward from the first end of the body 18 in the length direction is exposed on the outside of the encapsulant 2. The igniter 183 is exposed on the outside of the encapsulant 2.

[0115] The sealing body 2 forms a recessed groove 20 that is concave from the outside to the inside at the position of the hot glue injection flow port 181.

[0116] In this embodiment, as Figure 4 and Figure 5 As shown, when the control module is placed in the injection mold for injection molding and sealing, multiple bodies 18 are located in multiple injection cavities. A hot glue injection flow channel is formed at the hot glue injection flow port 181 on the body 18, which is beneficial to set the glue inlet directly opposite the hot glue injection flow port 181. The depth dimension of the glue inlet is increased in the width direction of the body 18, thereby increasing the thickness of the glue gate material formed after injection molding and sealing. This makes it easier to use a punching tool to punch and remove the formed glue gate material, which is beneficial to remove the glue gate material and form a recessed groove 20 from the outside to the inside. This helps to prevent the glue gate from remaining protruding width dimension and affecting the positioning accuracy of the subsequent processing steps of the control module.

[0117] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, the body 18 has two hot glue injection ports 181 facing each other in the width direction, and the sealing body 2 has two opposite recessed grooves 20; furthermore, in the production of such... Figure 4 During the process of controlling the electronic detonator as shown, it is necessary to... Figure 1 and Figure 2 The control module for the electronic detonator shown is constructed by mounting a storage capacitor, a control chip, a terminal block 18, an igniter 183, and multiple electronic components onto the board 1. This results in the control module described in this embodiment. The control module is then further disassembled into the following configuration: Figure 3 The injection molding module unit shown is to be injection molded and sealed. It is then placed into the injection cavity within the injection mold for injection molding and sealing, resulting in ten electronic detonator control modules. It should be noted that placing the injection molding module unit to be injection molded and sealed into the injection cavity within the injection mold is not the focus of this application, and the related injection molding and sealing process can be referenced from existing technologies in the field, or designed based on existing injection molding technologies in the field, and will not be elaborated further here. Furthermore, the structure of the injection mold can also be designed based on existing injection mold technologies in the field, and will not be elaborated further here. Additionally, in this embodiment… Figure 4 The single control module shown is the final electronic detonator control module.

[0118] In this embodiment, as Figure 3 and Figure 4 As shown, after the injection molding module unit to be sealed is placed in the injection cavity of the injection mold and sealed, a sealed control module including ten electronic detonator control modules is obtained. The sealed control module is then disassembled and other supporting components are removed to obtain the following... Figure 4 The electronic detonator control module shown is illustrated. It should be noted that in this embodiment, the single control module that has completed the sealing process is the electronic detonator control module that needs to be produced.

[0119] In this embodiment, after the injection molding module unit to be sealed is placed in the injection cavity of the injection mold for injection sealing, the sprue material and the sprue material need to be removed to obtain a control module including ten electronic detonator control modules to complete the sealing. In this embodiment, the sprue material and the sprue material are removed by punching with a punching tool set in the injection module. The structure of the punching tool can be various, and the structure of the punching tool can also be designed based on this application. Moreover, the punching tool is not the focus of this application and will not be described in detail here.

[0120] In this embodiment, when the lateral spacing between two adjacent bodies 18 on the plate 1 is small, for example, the lateral spacing between two adjacent bodies 18 on the plate 1 is 2.5mm, and the thickness requirement of the sealant 2 is 0.8mm, then without a recessed hot glue injection passage 181 on the body 18, the punching tool can only punch through a 0.7mm thick glue, requiring a very fine punching tool. Furthermore, a small punching tool makes it difficult to guarantee its strength or increases the cost of using the punching tool. In this embodiment, by providing a recessed hot glue injection passage 181 on the body 18, for example, with a recess depth of 1mm, the spacing between the two hot glue injection passages 181 of two adjacent bodies 18 is 4.5mm. A punching tool with a thickness of 2.9mm can be used, which helps to enhance the strength of the punching tool and reduce the punching difficulty. It should be noted that there are various types of lateral spacing between two adjacent bodies 18 on the plate 1. The numerical examples above are only used to explain this application. In addition, the left side of the leftmost body 18 of every ten bodies 18 has a large space for arranging the cutting tool, and the right side of the rightmost body 18 of every ten bodies 18 also has a large space for arranging the cutting tool. When the bodies 18 at these two positions are provided with hot colloid injection flow ports 181, it is also easier to remove them by punching with a punching tool.

[0121] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the electronic detonator control module obtained during production includes: Figure 6 The body 18 shown is formed on the plate 1 by cutting or other processing techniques in the early stage of production.

[0122] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the front end of the body 18 in this embodiment is provided with two conductive connection holes 184. The terminal block 182 in this embodiment includes two conductive connection leads 1821 and a connecting block 1822. The rear ends of the two conductive connection leads 1821 are respectively installed in the two conductive connection holes 184, and the rear ends of the conductive connection leads 1821 are encapsulated on the body 18 by the connecting block 1822. The connecting block 1822 in this embodiment is a sealing block. The connecting block 1822 is formed by injection molding. The forming of the connecting block 1822 is not the focus of this application, and the forming of the connecting block 1822 can also refer to the prior art in this field, and will not be described in detail here.

[0124] The housing has an internal mounting cavity.

[0125] The aforementioned control module for the electronic detonator control module is installed inside the mounting cavity.

[0126] In this embodiment, the electronic detonator includes the control module for the electronic detonator control module described above.

[0127] It should be noted that the overall width dimension of the control module used for the electronic detonator control module includes both the width and height dimensions of the control module used for the electronic detonator control module; furthermore, the electronic detonator is not illustrated in this embodiment.
