Description

TECHNICAL FIELD

[0001] The utility model relates to the field of initiating explosive, especially to a circuit substrate structure, an electronic detonator control module containing the same and an electronic detonator. BACKGROUND

[0002] At present, electronic detonators are widely used in tunneling, danger-removal blasting, demolition blasting, mine rock separation, open-pit mine blasting and other occasions. The existing electronic detonator mainly includes a foot line, a plastic plug, a control module, an ignition bridge wire with a primer, a base drug and a base tube shell. In addition, during the production of the electronic detonator, the control module needs to be assembled into a protective shell for protection.

[0003] Further, in the electronic detonator industry, the outer diameter size specification of the electronic detonator is generally 7.0mm-7.2mm, and the protective shell for assembling the control module has certain specification and size limitation. The width size precision of the control module directly affects the smoothness and reliability of assembling the control module into the protective shell. When the width size of the control module is greater than the inner diameter of the protective shell, it is difficult to assemble the control module into the protective shell.

[0004] Further, the outside of the control module needs to be injection molded with a rubber layer to form an encapsulation layer for packaging. The thickness size of the rubber layer needs to at least wrap the energy storage capacitor mounted on the circuit board, and the thickness size of the rubber layer can be controlled within a certain thickness range. Therefore, the width size of the control module is mainly determined by the width size of the circuit board and the protruding size of the energy storage capacitor mounted on the circuit board. After the energy storage capacitor is mounted on the circuit board, the profile protruding size of the energy storage capacitor from the circuit board affects the width size of the control module.

[0005] In order to reduce the profile protruding size of the energy storage capacitor from the circuit board, the energy storage capacitor is mounted in the capacitor placement groove provided on the circuit board in the prior art, which can limit the width size of the control module within a suitable width size range to a certain extent. However, the width size of the circuit board for the control module is narrow, and the structure of the existing circuit board has its own defects due to the design of the structure. The energy storage capacitor mounted in the capacitor placement groove on the circuit board is prone to damage or even failure, which further leads to damage or even failure of the control module, reduces the yield of the control module, and reduces the blasting effect of the electronic detonator blasting operation. Therefore, ensuring the reliability and stability of the energy storage capacitor mounted in the capacitor placement groove on the circuit board has become a new problem. In addition, the circuit board is obtained by building a complete electronic connection system based on a circuit substrate, and the structure of the circuit substrate largely determines the structure of the circuit board. Therefore, there is an urgent need for a circuit substrate structure that is conducive to reducing the size of the energy storage capacitor protruding from the circuit board and improving the reliability and stability of the energy storage capacitor.

[0060] In order to more clearly illustrate the technical solutions in the present application, the drawings needed in the embodiment description will be briefly introduced. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor.

[0061] ​​Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other embodiments that can not be described in detail herein, and the present application is not limited to the embodiments described herein.

[0062] In one aspect of the present application, a circuit substrate structure is provided, as shown in Figures 1 to 4 comprising:

[0063] The body 1 is in a long plate structure, and the body 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 body 1. The body 1 forms a wide bridge 13 on one side in the width direction of the placement slot 10. The body 1 forms a narrow bridge 14 on the other side in the width direction of the placement slot 10. The narrow bridge 14 is arranged opposite to the wide bridge 13. The width dimension of the wide bridge 13 is greater than the width dimension of the narrow bridge 14. 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.

[0064] In the present embodiment, as shown in Figures 1 to 4 The body 1 in the present embodiment forms the wide bridge 13 on one side in the width direction of the placement slot 10, and forms the narrow bridge 14 on the other side in the width direction of the placement slot 10. Therefore, when the circuit is arranged on the body 1, the conductive circuit constituting the circuit can be arranged on the wide bridge 13. It is convenient to arrange the conductive circuit on the wide bridge 13 on one side of the placement slot 10 on the body 1. It is also advantageous to increase the spacing between the conductive circuit arranged on the wide bridge 13 on one side of the placement slot 10 and the energy storage capacitor 2 placed in the placement slot 10. Therefore, it is advantageous to avoid the adverse effects of static electricity or other electric energy flowing through the conductive circuit arranged on the wide bridge 13 on one side of the placement slot 10 on the energy storage capacitor 2. The reliability and stability of the energy storage capacitor 2 are improved. It is also advantageous to reduce the difficulty of arranging the conductive circuit on one side of the placement slot 10. Further, the narrow bridge 14 in the present embodiment can provide support for the outer side wall of the energy storage capacitor 2 arranged opposite to it. The energy storage capacitor 2 can be limited between the wide bridge 13 and the narrow bridge 14 in the width direction and can be lifted and positioned by the wide bridge 13 and the narrow bridge 14. The precision of the installation of the energy storage capacitor 2 on the body 1 is improved. It is also advantageous to reduce the size of the energy storage capacitor 2 protruding from the body 1 and to improve the reliability of the energy storage capacitor 2 limited in the placement slot 10. Therefore, the electronic detonator control module is produced by using the circuit substrate structure in the present embodiment. It is advantageous to improve the yield of the electronic detonator control module and to improve the blasting effect of the electronic detonator blasting operation.

[0065] In the present embodiment, as shown in Figure 1 and Figure 2As shown, the body 1 is in a long plate structure, specifically, the length dimension of the body 1 is three times or more than the width dimension, and the body 1 in the embodiment is approximately in a rectangular plate structure with a groove.

For example, if the width dimension of the body 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 body 1 through the placement through groove 10 can only be arranged within a width range of 0.7 mm in width dimension; it should be noted that the width dimension values of the body 1 in the above examples are only used to explain the present application, and are not used to limit the actual width dimension of the body 1.
