Description

Technical Field

[0001] This utility model relates to the field of blasting materials, and more specifically, to a split-type electronic detonator structure. Background Technology

[0002] Current electronic detonator structures generally consist of a base detonator, an electronic control module, and a plug with leads. Typically, the electronic control module and plug are connected and inserted together into the base detonator, secured using a bayonet process to form the overall electronic detonator structure, improving its sealing and waterproofing. In existing electronic detonator structures, only a certain amount of external energy needs to be input to the detonator's leads. The electronic control module's transducer converts electrical energy into heat energy to ignite the base charge, completing the detonation process. Therefore, this presents a certain degree of danger. Furthermore, because detonators are specialized products, they require specially qualified transport vehicles. Current electronic detonator structures, including the leads, significantly occupy transport space and increase weight, leading to higher transportation costs. Moreover, existing split-type electronic detonators generally only rely on sealing rings for waterproofing, which can be unreliable. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] Example 1

[0026] like Figures 1-4 As shown, the first aspect of this utility model provides a split electronic detonator structure, including: a base detonator 1, a lead wire sleeve 3, and an electronic control module 9;

[0027] The electronic control module 9 is installed inside the base detonator 1; the electronic control module 9 has an irregular structure.

[0028] One end of the electronic control module 9 is provided with a plug-in part 12; the tail end of the electronic control module 9 is also a plug-in part 12, which is used to connect with the female connector inside the lead wire sleeve 3 to ensure the overall circuit continuity.

[0029] One end of the electronic control module 9 is inserted into the lead wire sleeve 3. The lead wire sleeve 3 is provided with a plug-in female head 13. The plug-in female head 13 is connected to the plug-in part 12. One end of the plug-in female head 13 is provided with a lead wire 4.

[0030] According to an embodiment of the present invention, a plurality of protrusions 2 are provided on the outer side of one end of the electronic control module 9, and a locking hole 5 is provided on the outer side of the lead wire sleeve 3, with the protrusions 2 cooperating with the locking hole 5.

[0031] According to an embodiment of the present invention, a guide protrusion 6 is provided on one side of the electronic control module 9, and a guide groove 7 is provided on one side of the lead wire sleeve 3. When one end of the electronic control module 9 is inserted into the lead wire sleeve 3, the guide protrusion 6 moves inside the guide groove 7.

[0032] It should be noted that a guide protrusion 6 has been added to the injection molding structure of capacitor section 15 to match the groove on lead sleeve 3, so as to clearly define the insertion direction of electronic control module 9 and ensure the consistency and correspondence of the direction. At the same time, there are multiple sets of oblique insertion protrusions 2 in different directions around the injection molding surface, which play an anti-detachment function when electronic control module 9 is combined with lead sleeve 3, and ensure the structural firmness.

[0033] According to an embodiment of this utility model, the basic detonator 1 is equipped with a high explosive or an initiating explosive.

[0034] According to an embodiment of the present invention, a sealing ring 11 is provided inside the lead wire sleeve 3, and the sealing ring 11 is located at one end of the plug-in female 13.

[0035] It should be noted that the sealing ring 11 can improve the overall sealing and waterproof performance of the structure.

[0036] According to an embodiment of the present invention, the electronic control module 9 includes an ignition section 8, an intermediate section 14, and a capacitor section 15. The ignition section 8 is in direct or indirect contact with a high explosive or detonating agent. The intermediate section 14 is disposed between the ignition section 8 and the capacitor section 15. The capacitor section 15 is provided with a capacitor. The capacitor section 15 is connected to a plug-in part 12. The plug-in part 12 includes a plug-in piece or a plug-in post.

[0037] It should be noted that the ignition section 8 adopts a quasi-sharp-angle shape, and uses an ignition resistor as a transducer at the very tip. Compared with ordinary ignition resistors, the resistance wire of this ignition resistor ignites in the forward direction, which is more conducive to igniting the explosive in the base detonator 1 and improving the reliability of the explosive detonation.

[0038] The intermediate section 14 is used for insertion into the detonator casing, and the outer diameter of the injection-molded capacitor section 15 is slightly larger, possibly serving as a limit for casing insertion. The spring contact 10 can directly contact the casing wall for direct electrostatic discharge, etc.

[0039] Compared to the front end, the PCB board at the rear of the middle section 14 is narrower to accommodate the external injection molding layer and the detonator casing, preventing the PCB board from breaking due to excessive clamping force. The electronic control module 9, by clamping the detonator casing, further enhances the sealing and waterproofing of the detonator charge.

[0040] The capacitor is located at the rear, which can reduce the difficulty of component layout at the front of the PCB board. At the same time, the lead sleeve 3 can also add an extra layer of protection.

[0041] According to an embodiment of the present invention, a spring piece 10 is provided on the middle section 14, and a circuit board is provided inside the middle section 14.

[0042] According to the embodiments of this utility model, the plug-in female head 13, the lead wire 4 and the lead wire sleeve 3 are integrally formed by injection molding.

[0043] In summary, this application enables the transport of the hazardous basic detonator 1 separately, while other ordinary components can be transported in a conventional manner. After on-site assembly at the place of use, a complete electronic detonator can be formed. On the one hand, this can greatly increase the transport quantity of the basic detonator 1 and reduce costs, and on the other hand, it can reduce the dangers during transportation.
