Description

Technical Field

[0001] This utility model relates to the field of electronic delay-induced cracking tube devices, and in particular to a PCB circuit board connector for electronic delay-induced cracking tubes. Background Technology

[0002] Fracturing tubes are widely used in non-explosive blasting operations in quarries, tunnel excavation, and mining.

[0003] Compared to the use of traditional detonators and explosives, carbon dioxide fracturing devices do not produce open flames, heat sources, or various toxic and harmful gases generated by chemical reactions, resulting in high safety performance during construction.

[0004] PCB connectors are used to connect lead wires to control module PCBAs. Conventional lead wire to PCB connections often employ soldering or riveting. While both methods allow for quick connection, they suffer from insufficient strength after connection, making them prone to lateral deformation or even detachment during assembly. This can lead to displacement of the sealing plug and module, misalignment, circuit breaks, and negatively impact subsequent assembly. Summary of the Invention

[0005] The purpose of this utility model is to provide a PCB circuit board connector for an electronic delay cracking tube, so as to solve the problem that the existing soldering or riveting methods have insufficient strength after connection, are prone to lateral deformation or even fall off, causing displacement of the sealing plug and module, misalignment, and affecting subsequent assembly.

[0006] The technical solution of this utility model is as follows: A PCB circuit board connector for an electronic time-delay rupture tube, comprising a PCB circuit board, wherein a sealing plug is connected to the PCB circuit board, and a sealing nut is fitted onto the outer surface of the sealing plug.

[0007] One end of the sealing plug, located to the right of the sealing nut, has lead wires, and the other end, located to the left of the sealing nut, has multiple sets of lead wire cores. The lead wire cores are connected to each other on the PCB circuit board. One end of the sealing plug, located at the edge of the lead wire cores, has multiple sets of positioning grooves.

[0008] The PCB circuit board has an ignition head at one end near the sealing plug and multiple sets of extended protruding fixing connectors at the other end, which are used to be inserted into the inner side of the positioning groove.

[0009] Furthermore, the PCB circuit board has lead pads at the lead wire core connection points.

[0010] Furthermore, the ignition head forms an outward-facing connection port at the other end away from the PCB circuit board.

[0011] Furthermore, the PCB circuit board is wrapped with a protective shell.

[0012] Furthermore, the outer side of the protective shell is provided with multiple sets of positioning holes.

[0013] Furthermore, the sealing nut has an outward-facing opening at one end near the PCB circuit board, and a threaded connecting groove is provided on its inner sidewall. The sealing plug with the lead wire at one end passes through the bottom wall of the connecting groove.

[0014] Furthermore, a raised annular sealing boss is formed on the outer surface of the sealing plug, located inside the connecting groove.

[0015] Furthermore, the sealing boss is located near the PCB circuit board and forms a limiting annular groove on the outer surface of the sealing plug, and a sealing ring is provided inside the limiting annular groove.

[0016] Furthermore, multiple sets of protruding limiting blocks are provided at the edge where the sealing plug connects to the lead wire.

[0017] The advantages of this invention compared to existing technologies are as follows: By providing a protruding fixing connector at one end of the formed PCB circuit board and a fixing groove at the sealing plug end, the plug-in connection method increases the stability of the connection between the PCB circuit board and the fixing groove, thereby ensuring the stability of the connection between the PCB circuit board and the sealing lead wire core. This method, through the design and cooperation of the PCB circuit board and the sealing plug, not only enables rapid connection between the lead wire and the PCB, but also enhances the lateral strength of the sealing plug and PCB connection assembly, improving the overall rigidity of the product.

[0028] See Figure 1-7This invention discloses an electronic time-delay rupture tube PCB circuit board connector, comprising a PCB circuit board 2, a sealing plug 4 connected to the PCB circuit board 2, a sealing nut 5 fitted on the outer surface of the sealing plug 4, a lead wire 7 at one end of the sealing plug 4 and a plurality of lead wire cores 9 at the other end of the sealing plug 4 and the sealing nut 5, the lead wire cores 9 being connected to the PCB circuit board 2 in cooperation, and a plurality of positioning grooves 41 at one end of the sealing plug 4 and the edge of the lead wire cores 9; an ignition head 1 at one end of the PCB circuit board 2 near the sealing plug 4, and a plurality of extended protruding fixing connectors 21 at the other end, the fixing connectors 21 being used to insert into the positioning grooves 41. In use, the electronic time-delay rupture tube PCB circuit board connector is first threadedly connected to a waterproof nut 903, so that the PCB circuit board is placed in the inner space 902 of the waterproof nut 903, and the waterproof nut 903 is then connected to the rupture tube body 901. Meanwhile, the connection between the sealing plug 4 and the PCB circuit board 2 adopts an insertion method. An extended protruding fixing connector 21 is provided at the connection end of the PCB circuit board 2 and the sealing plug 4, and the end face of the fixing connector 21 forms a U-shaped opening groove 201. The positioning grooves 41 are symmetrically arranged on the left and right sides of the edge of the sealing plug 4. The size of the positioning grooves 41 fits tightly with the U-shaped opening grooves 201 on the PCB. During assembly, the positioning groove on the sealing plug is inserted into the corresponding U-shaped groove on the PCB. After assembly, the lead wire core is just in contact with the PCB pad, achieving initial positioning of the lead wire and the PCB. No displacement occurs between the PCB and the sealing plug, facilitating soldering. After soldering, the lead wire core is connected to the PCB. The positioning groove provides better radial strength to the sealing plug, preventing displacement and deformation under lateral forces, facilitating subsequent assembly and improving reliability. The connection structure between the lead wire and the PCB is not damaged during assembly, ensuring reliability.

[0029] See Figure 1-3 Specifically, to further improve the connection stability between the PCB circuit board 2 and the lead wire core 9, the PCB circuit board 2 is provided with lead wire pads 20 at the connection point of the lead wire core 9. Of course, lead wire pads can also be provided at the connection point between the gunpowder head 1 and the PCB circuit board 2 to increase the connection stability between the two.

[0030] Specifically, the other end of the ignition head 1 away from the PCB circuit board 2 forms an outward-facing connection port 10, which facilitates connection with the ignition wire.

[0031] Specifically, the PCB circuit board 2 is wrapped with a protective shell 3. The outer side of the protective shell 3 is provided with multiple sets of positioning holes 30. The protective shell 3 is made of plastic and is wrapped around the outside of the PCB circuit board 2 to provide protection for the capacitors and components on the PCB circuit board 2. At the same time, the multiple sets of positioning holes 30 are provided to position the capacitors during the production process, ensuring the relative position accuracy of the internal components and the uniform thickness of the outer plastic protective layer.

[0032] Specifically, the sealing nut 5 has an outward-facing opening at the end near the PCB circuit board 2, and a threaded connecting groove 50 on its inner sidewall. The sealing plug 4, with the lead wire 7, passes through the inner bottom wall of the connecting groove 50, forming a sealing nut 5 with the connecting groove 50 for easy connection with the waterproof nut 903 with an external threaded end. In use, the nut 5 with the PCB circuit board 2 is placed inside the waterproof nut 903, and the threaded connecting groove 50 on its inner sidewall engages with the threaded end of the waterproof nut 903, while the end with the lead wire 7 is exposed for easy wiring. Simultaneously, to improve the sealing performance between the sealing plug 4 and the sealing nut 5, a raised annular sealing boss 43 is formed on the outer surface of the sealing plug 4, inside the connecting groove 50. A limiting annular groove 42 is formed on the side of the sealing boss 4 near the PCB circuit board, and a sealing ring 8 is provided inside the limiting annular groove 42. Multiple sets of raised limiting blocks 40 are provided at the connection edge between the sealing plug 4 and the lead wire 7. As the sealing nut 5 is continuously tightened, the mating section of the waterproof nut 903 continuously presses against the sealing ring 8 and the annular sealing boss 43 located inside the connecting groove 50 until it is fully tightened. The limiting block 40 restricts the relative displacement distance of the nut 5, ensuring that the nut 5 remains at the tail of the sealing plug 4, facilitating nut assembly.

[0033] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
