[0055] In one aspect of the present application, an electronic detonator control module is provided, as shown in Figures 1 to 4 The electronic detonator control module comprises:

[0056] The control circuit board 1 is in a long plate structure, the control circuit board 1 is provided with a placement slot 10 for placing an energy storage capacitor 2, the placement slot 10 extends along the length direction of the control circuit board 1, the control circuit board 1 forms a wide edge bridge 13 on one side in the width direction of the placement slot 10, the control circuit board 1 forms a narrow edge bridge 14 on the other side in the width direction of the placement slot 10, the narrow edge bridge 14 is arranged opposite to the wide edge bridge 13, the width size of the wide edge bridge 13 is greater than the width size of the narrow edge bridge 14, and when the energy storage capacitor 2 is placed in the placement slot 10, the energy storage capacitor 2 is located on the inner side of the placement slot 10 in the horizontal direction;

[0057] The first end in the length direction of the control circuit board 1 is provided with a circuit arrangement area one on one side of the placement slot 10, the second end in the length direction of the control circuit board 1 is provided with a circuit arrangement area two on the other side of the placement slot 10, and the wide edge bridge 13 is provided with a circuit arrangement area three;

[0058] The control circuit board 1 is provided with control circuits, which include control circuit section one, control circuit section two and control circuit section three. Control circuit section one is arranged in circuit arrangement area one, control circuit section two is arranged in circuit arrangement area two, and control circuit section three is arranged in circuit arrangement area three and is electrically connected between control circuit section one and control circuit section two.

[0059] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the control circuit board 1 forms a wide-side bridge 13 on one side of the width direction of the slot 10 and a narrow-side bridge 14 on the other side of the width direction of the slot 10. This facilitates the formation of circuit arrangement area one, circuit arrangement area two, and circuit arrangement area three on the control circuit board 1. Therefore, when arranging circuits on the control circuit board 1, control circuit part one can be arranged in circuit arrangement area one, control circuit part two in circuit arrangement area two, and control circuit part three in circuit arrangement area three. This facilitates the dispersed arrangement of control circuits on the control circuit board 1, avoiding excessively dense control circuit layout that could lead to leakage between conductive lines and affect the stability and reliability of the control circuit. It also facilitates the arrangement of electronic components at both ends of the control circuit board 1, fully utilizing the usable area of ​​the control circuit board 1 for arranging conductive lines and electronic components. Furthermore, it helps to further reduce the size of the control circuit while meeting the space requirements for circuit arrangement. The dimensions of the circuit board 1 are adjusted; furthermore, this increases the distance between the control circuit section 3 and the energy storage capacitor 2 placed in the placement slot 10, thereby helping to avoid the adverse effects of static electricity or other electrical energy flowing through the control circuit section 3 on the energy storage capacitor 2, improving the reliability and stability of the energy storage capacitor 2, and also reducing the difficulty of arranging the control circuit section 3 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, and the energy storage capacitor 2 can be limited between the wide side bridge 13 and the narrow side bridge 14 in the width direction and can achieve the lifting and positioning of the wide side bridge 13 and the narrow side bridge 14, improving the accuracy of the energy storage capacitor 2 installed on the control circuit board 1, and also helping to reduce the size of the energy storage capacitor 2 protruding from the control circuit board 1 and improve the reliability of the energy storage capacitor 2 being limited in the placement slot 10; thus, it can improve the quality and yield of the electronic detonator control module and improve the blasting effect of the electronic detonator blasting operation.

For example, if the width dimension of the control circuit board 1 is 4.0 mm, and the width dimension of the energy storage capacitor 2 is 3.0 mm, the sum of the width dimensions of the wide side bridge 13 and the narrow side bridge 14 is 1.0 mm, when the width dimension of the narrow side bridge 14 is 0.3 mm, the width dimension of the wide side bridge 13 is 0.7 mm, and the conductive circuit arranged on the wide side bridge 13 on one side of the control circuit board 1 passing through the placement through slot 10 can only be arranged within a width range of 0.7 mm in width; it should be noted that the numerical value of the width dimension of the control circuit board 1 in the above example is only used to explain the present application, and is not used to limit the actual width dimension of the control circuit board 1.

[0073] In one embodiment of the present application, the first control circuit part one, the first control circuit part two and the first control circuit part three form a front circuit, the second control circuit part one, the second control circuit part two and the second control circuit part three form a back circuit, and the front circuit and the back circuit are electrically connected to constitute the control circuit.

[0074] In the embodiment, the front circuit and the back circuit in the embodiment are electrically connected to form the control circuit, so as to arrange the electronic components on the two sides of the control circuit board 1, make full use of the available area of the control circuit board 1 to arrange the conductive circuit and the electronic components, and further reduce the size of the control circuit board 1 while meeting the space requirement of the circuit arrangement.

[0075] In the embodiment, as shown in Figure 1 and Figure 2 , the front end of the control circuit board 1 is a component arrangement end one 11, and the rear end of the control circuit board 1 is a component arrangement end two 12.

Further, the specific structure of the control circuit is not shown in the embodiment, and the specific structure of the control circuit and the wiring mode of the control circuit can be flexibly adjusted according to the functional requirements of the electronic detonator control module. The specific structure of the control circuit and the wiring mode of the control circuit can also have multiple forms, which will not be described here.

[0076] In one embodiment of the present application, as shown in Figures 1 to 4 , the control circuit part three is arranged along the length direction of the wide bridge 13. The distance between the side of the control circuit part three in the width direction and the outer side wall of the energy storage capacitor 2 opposite to the control circuit part three is any value in the range of 0.2mm-0.5mm.

[0077] In the embodiment, as shown in Figures 1 to 4 , the control circuit part three in the embodiment is arranged along the length direction of the wide bridge 13, which is beneficial to increase the distance between the control circuit part three and the outer side wall of the energy storage capacitor 2 opposite to the control circuit part three. Further, the distance between the side of the control circuit part three in the width direction and the outer side wall of the energy storage capacitor 2 is any value in the range of 0.2mm-0.5mm, which is beneficial to ensure that the control circuit part three has a suitable distance from the outer side wall of the energy storage capacitor 2, thereby avoiding the adverse effects of static electricity or other electric energy flowing through the control circuit part three on the energy storage capacitor 2, and improving the reliability and stability of the energy storage capacitor 2.

[0078] 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.

[0079] One embodiment of this application, such as Figures 1 to 4 As shown, there is a gap between the outer wall of the energy storage capacitor 2 and the inner wall of the placement slot 10, forming a gap. The size of the gap is any value between 0.1mm and 0.3mm. After the control circuit board 1 and the energy storage capacitor 2 are injection molded and sealed, a sealing layer is formed in the gap.

[0080] In this embodiment, as Figures 1 to 4 As 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 control circuit board 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 beneficial for the sealing layer one to block the static electricity or other electrical energy flowing through the control circuit section three arranged on one side of the placement slot 10, so as to avoid the static electricity or other electrical energy flowing through the control circuit section three arranged 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.

[0081] 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.

[0082] One embodiment of this application, such as Figures 1 to 4 As shown, the width dimension of the wide-side bridge 13 is A, and the width dimension of the narrow-side bridge 14 is B. The relationship between the width dimensions of the wide-side bridge 13 and the narrow-side bridge 14 is as follows:

[0083] A = M * B;

[0084] Where M is any value between 1.2 and 3.0.

[0085] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the width relationship between the wide-side bridge 13 and the narrow-side bridge 14 is A=M*B, where M is any value between 1.2 and 3.0. This is beneficial for making the dimensions of the wide-side bridge 13 and the narrow-side bridge 14 suitable, ensuring that the wide-side bridge 13 has a suitable width for arranging the control circuit section 3, and reducing the difficulty of arranging the control circuit section 3 on the wide-side bridge 13.

[0086] In this embodiment, given a fixed width of the control circuit board 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 power, 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 control circuit board 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 control circuit board 1 in the examples above are only used to explain this application and are not intended to limit the actual width of the control circuit board 1.

[0088] In this embodiment, as Figure 1As shown, the width dimension of the wide side bridge 13 in the embodiment is any value within 0.6mm-1.6mm, which is conducive to ensuring that the wide side bridge 13 has a suitable width for arranging the control circuit part three and reducing the difficulty of arranging the control circuit part three on the wide side bridge 13; further, the width dimension of the narrow side bridge 14 is any value within 0.3mm-0.8mm, which is conducive to ensuring that the narrow side bridge 14 can provide reliable support to the outer side wall of the energy storage capacitor 2 arranged opposite to the narrow side bridge 14, and improving the reliability of the energy storage capacitor 2 being limited in the placement through slot 10; in addition, the width dimensions of the wide side bridge 13 and the narrow side bridge 14 are suitable, which is also conducive to the placement through slot 10 having sufficient space to accommodate the energy storage capacitor 2 in the width direction.

[0089] It should be noted that the narrow side bridge 14 can provide support to the outer side wall of the energy storage capacitor 2 arranged opposite to the narrow side bridge 14, which can include that the narrow side bridge 14 directly abuts against the outer side wall of the energy storage capacitor 2 to provide direct support to the outer side wall of the energy storage capacitor 2, or can include that a pad layer is arranged between the narrow side bridge 14 and the outer side wall of the energy storage capacitor 2, and the narrow side bridge 14 provides support to the pad layer arranged between the narrow side bridge 14 and the outer side wall of the energy storage capacitor 2, and then the narrow side bridge 14 provides indirect support to the outer side wall of the energy storage capacitor 2.

[0090] An embodiment of the present application is as shown in Figure 2 and Figures 1 to 4 When the energy storage capacitor 2 is placed in the placement through slot 10, the upper side wall and the lower side wall of the energy storage capacitor 2 in the vertical direction respectively protrude out of the placement through slot 10.

[0091] In the embodiment, as shown in Figure 1 the upper side wall and the lower side wall of the energy storage capacitor 2 in the vertical direction in the embodiment respectively protrude out of the placement through slot 10, which is conducive to the vertical central surface of the energy storage capacitor 2 being close to the vertical central surface of the control circuit board 1, and the upper side wall and the lower side wall of the energy storage capacitor 2 in the vertical direction protruding out of the placement through slot 10 have equal or similar dimensions, which is conducive to reducing the size of the energy storage capacitor 2 protruding out of the control circuit board 1.

[0092] An embodiment of the present application is as shown in Figure 2 and Figure 1 The narrow side bridge 14 has a gap two formed between the outer side wall of the energy storage capacitor 2 arranged opposite to the narrow side bridge 14 in the width direction, and the size of the gap two is any value within 0.1mm-0.3mm, when the control circuit board 1 and the energy storage capacitor 2 are injection molded with the encapsulation glue, the gap two is formed with an encapsulation glue layer two, and the outer side wall of the energy storage capacitor 2 opposite to the narrow side bridge 14 is supported by the encapsulation glue layer two and the narrow side bridge 14.

[0093] In the embodiment, as shown in Figure 2 and Figure 1As shown, the size of the gap two in the embodiment is any value in 0.1mm-0.3mm, and the size of the gap two is suitable for forming a second encapsulation layer in the gap two after the control circuit board 1 and the energy storage capacitor 2 are injection molded, which is beneficial to the second encapsulation layer formed after injection molding to have a suitable thickness, and is beneficial to the reliable support of the energy storage capacitor 2 to the outer side wall of the narrow edge bridge 14 opposite to the narrow edge bridge 14 through the second encapsulation layer and the narrow edge bridge 14.

[0094] In the embodiment, as shown in Figure 2 and Figure 1 , the energy storage capacitor 2 in the embodiment has a cylindrical structure, and the width of the placement through groove 10 in the horizontal direction is greater than the outer diameter of the energy storage capacitor 2; in addition, the placement through groove 10 in the embodiment can also be designed to be approximately rectangular structure, and the structure of the placement through groove 10 can also be designed to other shapes according to the shape of the energy storage capacitor 2.

[0095] Further, as shown in Figure 2 and Figure 1 , the energy storage capacitor 2 in the embodiment has a cylindrical structure, which means that the main part of the energy storage capacitor 2 has a cylindrical structure, and the energy storage capacitor 2 is also connected with a conductive connecting pin 20; in addition, the energy storage capacitor 2 can also be designed to other shapes according to the needs.

[0096] In the embodiment, as shown in Figure 2 and Figures 1 to 4 , the energy storage capacitor 2 in the embodiment has a cylindrical structure, and the gap one specifically refers to the distance between the point where the vertical center plane of the energy storage capacitor 2 and the control circuit board 1 coincides with the left side arc line of the energy storage capacitor 2 and the left side wall of the narrow edge bridge 14 after the energy storage capacitor 2 is placed in the placement through groove 10.

[0097] It should be noted that after the electronic detonator control module is injection molded, the encapsulation formed by the injection molding encapsulates the entire energy storage capacitor 2, and the encapsulation formed by the injection molding also encapsulates the electronic elements mounted on the control circuit board 1, and the terminal 3 and the ignition device 4 are exposed outside the encapsulation.

When the control circuit board 1 is injection molded and sealed, the avoiding recessed groove 17 forms a channel structure through which the hot glue can pass. The avoiding recessed groove 17 increases the channel structure through which the hot glue can pass for the control circuit board 1 placed in the injection molding cavity of the injection mold, which is beneficial to the flow of the hot glue between the upper and lower sides of the control circuit board 1. It also improves the smoothness of the flow of the hot glue between the upper and lower sides of the control circuit board 1, which is beneficial to reduce the injection pressure, thereby improving the stability of the injection molding and sealing quality of the control circuit board 1, and is beneficial to form a high-quality sealing body on the outside of the control circuit board 1.

[0100] In the embodiment, during the injection molding and sealing of the control circuit board 1, the control circuit board 1 is first placed in the injection molding cavity of the injection mold. The injection mold has an injection channel on the mold. The injection channel is located on the upper side or the lower side of the control circuit board 1. When the hot glue is introduced into the injection molding cavity through the injection channel, the hot glue introduced into the injection molding cavity is mainly located on one of the upper side or the lower side of the control circuit board 1.
