Description

Technical Field

[0001] This application relates to the field of blasting equipment technology, specifically to an electronic detonator. Background Technology

[0002] In the field of blasting, electronic detonators can be controlled by an electronic control system to control the blasting process, ultimately detonating the electronic detonator via an initiator. In use, the electronic detonator is connected to leads via a connecting structure, then the leads are connected to a busbar, and finally the busbar is connected to the initiation device. This allows the detonation signal to be transmitted to the control circuit board via the busbar and leads. A delay chip sets a preset time delay, and then the control circuit board issues a detonation command based on the delay, thus achieving detonation control.

[0003] The related electronic detonator structure includes a lead connector, an electronic control module, and a detonator housing filled with explosive. The lead connector is connected to a lead wire and has a female connector. The electronic control module includes a control circuit board and a male connector electrically connected to the control circuit board. The electronic control module is connected inside the detonator housing, and the male connector and female connector of the electronic control module are mated together. Specifically, the male connector of the electronic control module includes a detonator plug disposed inside the detonator housing and a male connector connected to the detonator plug and electrically connected to the detonation PCB board. The detonator plug is held and fitted against the inner wall of the detonator housing by multiple annular limiting protrusions. The lead connector includes a lead housing, a lead wire head, and a connecting bracket. The end of the lead wire head away from the lead wire forms a female connector that mates with the male connector, and the lead wire head is installed inside the lead housing via the connecting bracket. During assembly, the lead wire ends need to be manually assembled into the lead wire housing through the connecting bracket to form a lead wire connector. The electronic control module is then assembled into the detonator housing. Finally, the female connector of the lead wire connector is plugged into the male connector of the electronic control module to complete the assembly of the electronic detonator.

[0004] The electronic detonators mentioned above have the following defects in actual assembly and use: The electronic detonator has a complex structure, and during assembly, the electronic control module and the detonator housing, as well as the lead wire head, lead wire housing and connecting bracket of the lead wire connector, all need to be assembled manually. The assembly steps are cumbersome, resulting in low production efficiency. In addition, manual assembly inevitably leads to the possibility of poor sealing of the male plug of the electronic control module or the female plug of the lead wire connector, which poses a threat to the safety of the workers.

A lead wire connector has two first conductive elements that are respectively connected to the lead wire. The ends of the two first conductive elements away from the lead wire form a first plug end. The two first conductive elements are injection molded to form a first injection molded part for fixing and insulating the two first conductive elements. The first injection molded part and the first conductive element are covered with a first rubber plug extending to the lead wire. An electronic control module has two second conductive elements respectively connected to a control circuit board. The ends of the two second conductive elements away from the control circuit board form second plug terminals. The two second conductive elements are injection molded into second injection molded parts for fixing and insulating the two second conductive elements. The outer sides of the second injection molded parts and the second conductive elements are covered with second rubber plugs extending to the control circuit board. The second plug terminals mate with the first plug terminals to electrically connect the electronic control module to a lead wire connector. A detonator housing filled with explosives is inserted into the electronic control module, and the insertion end of the detonator housing is sealed to the first rubber plug.

[0009] In some embodiments, the first rubber plug is injection molded onto the lead connector, and the second rubber plug is injection molded onto the electronic control module.

[0010] In some embodiments, the outer side wall of the detonator housing insertion end is axially pressed with a plurality of spaced annular grooves, and each of the annular grooves forms a radially recessed annular protrusion that is embedded in the first rubber plug within the detonator housing.

[0011] In some embodiments, the first rubber plug extends axially toward the lead wire and covers at least a portion of the lead wire's outer skin.

[0012] In some embodiments, the outer circumferential wall of the second plug near the second insertion end is provided with a plurality of radially protruding annular protrusions along the axial direction.

[0013] In some embodiments, the first rubber plug is provided with a limiting step for the insertion end of the detonator housing to abut against it.

[0014] In some embodiments, the ends of the two first conductive members away from the lead wire are respectively configured as a hollow first outer spring and a hollow inner spring, with the inner spring disposed at the center of the first outer spring, and the first outer spring and the inner spring forming a female connector; the ends of the two second conductive members away from the control circuit board are respectively configured as a hollow second outer spring and a central conductive pin located at the center of the second outer spring and protruding outward along the axial direction, when the second connector is mated with the first connector, the central conductive pin contacts and conducts through the inner spring, and the second outer spring contacts and conducts through the inner wall of the first outer spring.

[0015] In some embodiments, the first outer spring, the inner spring, the second outer spring, and the central conductive needle are all stamped structures.

[0016] In summary, compared with related technologies, the electronic detonator of this application has the following advantages: The electronic detonator has a simple structure, and the assembly of the two first conductive components and the two second conductive components can be completed by injection molding in a mold, eliminating the need for manual assembly and thus greatly improving production efficiency and manufacturing precision. Furthermore, the two first conductive components of the lead wire connector and the two second conductive components of the electronic control module are first fixed by injection molding, and then encapsulated by secondary injection molding of first and second rubber plugs, respectively, improving their stability, waterproofness, safety, and tensile strength. Moreover, during the production of the lead wire connector of this electronic detonator, the two first conductive components are first connected to the two cores of the lead wire, and then a first injection molding compound for fixing and insulating the two first conductive components is injection molded in a mold.

During the production of the electronic control module, a second injection molded part for fixing and insulating the two second conductive parts is injection molded in a mold. The two second conductive parts are then soldered to the control circuit board, and the entire assembly is subjected to a second injection molding process in a low-pressure injection molding machine to form a second rubber plug, which covers the outside of the second injection molded part, the second conductive part, and part of the control circuit board. Then, the first plug end of the formed lead wire connector is inserted into the second plug end of the electronic control module and installed into the detonator housing. Finally, an automated crimping machine crimps the detonator housing to the first rubber plug of the lead wire connector to secure it. Therefore, the entire production or assembly of this electronic detonator is suitable for automated production and assembly, resulting in high production efficiency. Attached Figure Description

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] See Figures 1 to 11 As shown in the figure, this application discloses an electronic detonator. The structure of the electronic detonator includes a lead connector 1, an electronic control module 2, and a detonator housing 3 filled with explosive. The lead connector 1 is connected to a lead wire 4, and the lead connector 1 has a first plug-in end 103. The electronic control module 2 includes a control circuit board 201, a capacitor 202 connected to the control circuit board 201, and a second plug-in end 204. One end of the detonator housing 3 is closed, and the other end is open, which is set as the plug-in end. After the first plug-in end 103 of the lead connector 1 is engaged with the second plug-in end 204 of the electronic control module 2, the entire assembly is installed in the detonator housing 3. The electronic control module 2 encloses the explosive in the detonator housing 3, and the circuit board of the electronic control module 2 is at least partially plugged into the explosive. The capacitor 202 is used to store charge and release it when the trigger signal arrives. It is used in the initiation of electronic detonators to perform a preset time delay ignition. Then, the control circuit board 201 issues an initiation command according to the delay to realize initiation control.

[0024] In this embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lead wire connector 1 is located at the end of the lead wire 4. Each lead wire 4 has two wire cores 400, one live wire and one neutral wire. The two wire cores 400 are connected to two first conductive elements 100. The ends of the two first conductive elements 100 away from the lead wire form a first plug end 103. The two first conductive elements 100 are injection molded into a first injection molded part 102 for fixing and insulating the two first conductive elements 100. The first injection molded part 102 and the first conductive elements 100 are covered with a first rubber plug 106 extending to the lead wire.

[0025] For example, see Figure 3 and Figure 4 As shown, the two first conductive components 100 are riveted and fixed to the wire cores of the two leads at their ends. Then, the two first conductive components 100 are placed in a mold for injection molding of a first injection molded component 102. This first injection molded component 102 not only fixes the two first conductive components 100 into one piece, but also insulates and separates the two first conductive components 100 from each other. After the first injection molded component 102 is formed, the whole is placed into a low-pressure injection mold for injection molding of a first rubber plug 106. The first rubber plug 106 extends axially towards the lead direction and covers at least part of the outer sheath of the lead. That is, the first rubber plug 106 covers the outside of the first injection molded component 102 and the two first conductive components 100, as well as a portion of the outer sheath of the lead 4. This arrangement allows the lead connector 1 to undergo two injection molding processes. The first injection molding forms the first injection molded component 102, and the second injection molding forms the first rubber plug 106, thereby improving the structural stability, sealing performance, and tensile strength of the lead connector 1.

[0026] Furthermore, in this embodiment, a V-shaped or U-shaped clamping portion 101 is integrally formed at the end of each of the two first conductive members 100 away from the first plug-in end 103. The core 400 of the lead wire 4 is placed in the clamping portion 101, and then the clamping portion 101 clamps the core 400 of the lead wire 4 through a riveting process, so that it can withstand a static weight of 15 kg for 1 minute without loosening. In addition, the riveting process can be optimized to achieve riveting of two clamping portions 101 at the same time in one riveting, thereby improving production efficiency and adapting to automated production lines.

[0027] It is understood that the first plug-in end 103 of the lead wire connector 1 is a female plug; specifically, see [link to relevant documentation]. Figure 3 and Figure 4 As shown, the ends of the two first conductive elements 100 away from the lead wire are respectively set as a hollow first outer spring 104 and a hollow inner spring 105, and the inner spring 105 is disposed inside the first outer spring 104 and located at the center of the first outer spring 104. The first outer spring 104 and the inner spring 105 form a female connector.

[0028] In some embodiments, the first plug end 103 of the lead connector 1 can also be configured as a male plug, that is, the inner spring 105 is configured as a conductive pin protruding from the first outer spring 104.

[0029] Further in this embodiment, see Figure 5 and Figure 6 As shown, the electronic control module 2 includes a control circuit board 201, a capacitor 202 connected to the control circuit board 201, and two second conductive components 200. During production, the two second conductive components 200 are first placed in a mold for injection molding of a second injection molded component 203. This second injection molded component 203 not only fixes the two second conductive components 200 into one piece, but also insulates the two second conductive components 200 from each other. Then, the two second conductive components 200 are connected to the control circuit board 201 by welding, and the ends of the two second conductive components 200 away from the control circuit board 201 form second plug-in terminals 204. Finally, the whole assembly is placed into a low-pressure injection mold for injection molding of a second rubber plug 205, so that the second rubber plug 205 extends axially toward the control circuit board 201 and covers at least a portion of the control circuit board 201. That is, the second rubber plug 205 covers the second injection molded component 203, the outer side of the two second conductive components 200, the capacitor 202, and a portion of the control circuit board 201.

[0030] It is understood that the second connector 204 of the electronic control module 2 is a male connector; specifically, see [link to relevant documentation]. Figure 5 and Figure 6 As shown, the ends of the two second conductive elements 200 away from the control circuit board 201 are respectively configured as a hollow second outer spring 207 and a central conductive pin 208 located at the center of the second outer spring 207 and protruding outward along the axial direction of the second outer spring 207. The central conductive pin 208 and the second outer spring 207 are filled with insulation by the second injection molded part 203. When the second plug end 204 is mated with the first plug end 103 of the lead wire connector 1, the central conductive pin 208 is inserted into the central hole of the inner spring 105 and contacts and conducts with the inner spring 105. The second outer spring 207 is inserted into the first outer spring 104 and contacts and conducts with the inner wall of the first outer spring 104.

[0031] In some embodiments, if the first connector 103 of the lead connector 1 is configured as a male connector, then the second connector 204 of the electronic control module 2 can also be configured as a female connector, that is, the central conductive pin 208 is configured as an inner spring 105 located at the center inside the second outer spring 207. In other words, the male and female connectors of the lead connector 1 and the electronic control module 2 can be interchanged.

[0032] It is understood that in this embodiment, the assembly of the two first conductive components 100 and the two second conductive components 200 of the electronic detonator can be completed by injection molding in the mold without manual assembly, thereby greatly improving its production efficiency and manufacturing precision. In addition, the two first conductive components 100 of the lead wire connector 1 are first fixed by injection molding and then encapsulated by the first rubber plug 106 by secondary injection molding; and the two second conductive components 200 of the electronic control module 2 are first fixed by injection molding and then encapsulated by the second rubber plug 205 by secondary injection molding, thereby improving its structural stability, waterproofness, safety and tensile strength.

[0033] It is easy to understand that in this embodiment, the first plug end 103 of the lead wire connector 1 is a female plug and the second plug end 204 of the electronic control module 2 is a male plug. When the first plug end 103 and the second plug end 204 are plugged in, there is no need to consider the plugging angle. Just plug the two in to achieve conductivity and realize blind plugging, which is convenient for users to assemble.

[0034] In this embodiment, the lead wire connector 1 and the electronic control module 2 can be manufactured independently, which allows the lead wire connector 1 and the electronic control module 2 to be packaged and transported separately, and then assembled at the destination, which greatly improves the safety of transportation.

[0035] It is easy to understand that during the production of lead wire connector 1, the two first conductive components 100 are first connected and fixed to the two wire cores of the lead wire by riveting. Then, a first injection molded part 102 for fixing and insulating the two first conductive components 100 is injection molded in a mold. Then, the whole assembly is injection molded in a low-pressure injection molding machine to form a first rubber plug 106, which covers the outside of the first injection molded part 102, the first conductive components 100, and part of the lead wire. During the production of electronic control module 2, a second injection molded part for fixing and insulating the two second conductive components 200 is first injection molded in a mold. The plastic part 203 is then assembled by welding two second conductive parts 200 to the control circuit board 201. The assembly is then subjected to a second injection molding process in a low-pressure injection molding machine to form a second rubber plug 205. This second rubber plug 205 covers the outer side of the second injection molded part 203, the second conductive parts 200, and part of the control circuit board 201. Next, the first insertion end 103 of the formed lead connector 1 is inserted into the second insertion end 204 of the electronic control module 2 and installed into the detonator housing 3. Finally, an automated crimping device is used to crimp and fix the detonator housing 3 to the first rubber plug 106 of the lead connector 1. Therefore, the entire production or assembly of this electronic detonator is suitable for automated production and assembly, resulting in high production efficiency.

[0036] See Figure 7As shown, the detonator housing 3 is made of metal. After the first insertion end 103 of the lead connector 1 is inserted into the second insertion end 204 of the electronic control module 2, the insertion end of the detonator housing 3 is fitted onto the electronic control module 2 from the control circuit board 201 end until the end face of the insertion end of the detonator housing 3 abuts against the limiting step 107 on the first rubber plug 106 of the lead connector 1. Then, it is rolled in an automated crimping device, so that multiple spaced annular grooves 300 are axially crimped onto the outer wall of the insertion end of the detonator housing 3, and each annular groove 300 forms a radially recessed annular protrusion embedded in the first rubber plug 106 inside the detonator housing 3. This not only makes the connection of the detonator housing 3 more stable and firm, preventing the detonator housing 3 from falling off, but also plays a role in sealing and waterproofing.

[0037] In some embodiments, see Figure 5 and Figure 7 As shown, to further improve the connection strength of the detonator housing 3, multiple radially protruding annular protrusions 206 are provided on the outer circumferential wall of the second rubber plug 205 near the second insertion end 204. After the detonator housing 3 is fitted onto the electronic control module 2, the annular protrusions 206 abut against and seal against the inner wall of the detonator housing 3, thereby making the connection between the detonator housing 3 and the electronic control module 2 more secure and stable.

[0038] In this embodiment, both first conductive components 100 and both second conductive components 200 are conductive metal stamping parts. During production, they can be formed in a continuous stamping line using a strip material, thereby improving the manufacturing efficiency of the first conductive components 100 and the second conductive components 200. The semi-finished parts of the first conductive components 100 and the second conductive components 200 are connected by a strip material 5, which passes through a continuous stamping device to stamp the first conductive components 100 and the second conductive components 200 into finished products.

[0039] For example, see Figure 8 As shown, the first outer spring 104 and the clamping part 101 of the first conductive element 100 are integrally stamped structures formed by stamping metal sheets in a mold, and the first outer spring 104 is a hollow cylinder; see also Figure 9 As shown, the inner spring 105 and clamping portion 101 of the first conductive element 100 are integrally stamped structures formed from metal sheets in a mold, and the inner spring 104 is a hollow cylinder; see also Figure 10 As shown, the second outer spring 207 of the second conductive element 200 is a structure integrally stamped from a metal sheet in a mold, and the second outer spring 207 is a hollow cylinder; see also Figure 11 As shown, the central conductive pin 208 of the second conductive component 200 is a metal sheet integrally stamped in a mold, and the central conductive pin 208 is a cylindrical structure with a closed outer end and a hollow interior.

[0040] Further in this embodiment, see Figure 12 and Figure 13 As shown, during the production process of the male connector of the electronic control module 2, the strip 5 is stamped by a continuous stamping machine and then cut into groups of ten central conductive pin strips. The central conductive pin strip includes two parallel strips 5 and ten central conductive pins 208 connected to the two strips 5. Then, the ten central conductive pins 208 and the strip 5 near the central conductive pins 208 are pre-embedded into the injection mold for injection molding, thereby forming a group of ten second injection molded parts 203. The group of ten second injection molded parts 203 are wrapped around the outside of the strip 5 near the central conductive pins 208. This can increase the rigidity of the second injection molded parts 203 and prevent the second injection molded parts 203 from breaking. Moreover, in the subsequent process of punching the second injection molded parts 203, only one punching is needed to obtain the male connector of the electronic control module 2, thereby improving production efficiency.
