Abstract
Description
Technical Field
[0001] This invention belongs to the field of waterproofing technology, specifically relating to a waterproof tail clamp device and waterproofing method for an industrial electronic detonator. Background Technology
[0002] With the rapid development of modern blasting engineering technology, electronic detonators, due to their advantages such as precise detonation time, strong anti-interference ability, and high safety, are widely used in various complex environments such as open-pit mines, tunnel excavation, underwater operations, and underground mining. However, in these operational scenarios, blasting sites often experience environmental factors such as humidity, water accumulation, or heavy rain, making the connection points of the electronic detonator's tail wire highly susceptible to moisture or water ingress. This can lead to short circuits, poor contact, and even serious consequences such as the inability to transmit blasting signals or detonation failure. Therefore, how to improve the waterproof performance of the electronic detonator's tail wire connection device and ensure the stability and reliability of the circuit connection has become a key issue of long-term concern and research in this field.
[0003] Currently, electronic detonator tail wire connection devices typically employ a tail wire clip structure, a flip-top waterproof clip structure. Waterproof sealing is achieved by injecting waterproof silicone grease inside the clip body. This method has at least the following significant drawbacks:
[0004] (1) Limited waterproof stability: Since silicone grease is a fluid sealing medium, its sealing effect is easily weakened by temperature changes, usage time and environmental vibration, and its long-term protection capability is insufficient, and there is still a risk of water ingress and short circuit.
[0005] (2) Inconvenient operation: When used on site, the silicone grease inside the tail wire clip has strong adhesion. When operators plug and fasten the tail wire, they are easily affected by the silicone grease adhesion, which causes the plugging to be unsmooth or the tail wire to be difficult to fully insert, affecting the construction efficiency.
[0006] (3) Low production efficiency: Silicon grease injection is an additional process that requires precise injection and uniform distribution control during the assembly of the tail wire card, which increases the complexity and time cost of the production process and makes it difficult to achieve large-scale automated production.
[0007] (4) High maintenance costs: When the tail wire card is reused or contaminated with silicone grease during transportation and storage, it needs to be cleaned or re-greased, which increases the maintenance and operation burden. Summary of the Invention
[0008] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the existing technology by providing a waterproof tail wire clamp device and waterproofing method for industrial electronic detonators. The device has good waterproof performance, reasonable structure, simple operation, and is convenient for production.
[0009] The technical solution of the present invention to solve the above-mentioned technical problems is:
[0010] According to a first aspect of the present invention, a waterproof tail wire clamp device for an industrial electronic detonator is provided, comprising a housing and a slot sealing mechanism, wherein:
[0011] The housing is provided with lead wire channel and slot. The lead wire channel is used to insert the electronic detonator lead wire and is provided with an elastic waterproof sealing ring. The slot is used to place the wire.
[0012] The slot sealing mechanism is connected to the housing and is used to clamp the wire in the slot and make electrical connection with the electronic detonator lead wire, and to lock and seal the slot.
[0013] Optionally, the slot sealing mechanism includes a push rod, a central gear, a first rack, a second rack, a sealing rod, a terminal, and a cutting blade, wherein:
[0014] The push rod passes through the housing, with both ends extending out of the housing, and the push rod is equipped with a third rack, which is located inside the housing;
[0015] The central gear is located inside the housing and meshes with the third rack. The first rack and the second rack are symmetrically located on both sides of the central gear and mesh with it.
[0016] The two ends of the sealing rod are slidably mounted on the inner wall of the housing. The sealing rod includes a first sealing rod and a second sealing rod. The first sealing rod is connected to the first rack, and the second sealing rod is connected to the second rack.
[0017] The terminal is located inside the housing and is equipped with a blade. The cutting blade is located on the push rod and is electrically connected to the terminal.
[0018] When one end of the push rod is pressed, the third rack drives the central gear to rotate and drives the first rack and the second rack to move in opposite directions, thereby opening the slot to allow the wire to be placed.
[0019] Then, when the other end of the push rod is pressed, the third rack drives the central gear to rotate in the opposite direction and drives the first rack and the second rack to move in opposite directions respectively, so that the wire is locked in the slot and the slot is locked and sealed. At the same time, the blade cuts open the outer sheath of the wire to make it electrically connected to the terminal, and the cutting blade cuts open the outer sheath of the electronic detonator lead wire to make it electrically connected to the cutting blade.
[0020] Optionally, the housing has a first baffle inside, with the first baffle and the cutting blade located on opposite sides of the lead wire channel.
[0021] Optionally, both the first and second sealing rods are provided with sealing reinforcement components on their surfaces.
[0022] Optionally, both the first and second sealing rods are equipped with compression springs, and a second baffle is provided inside the housing, with the second baffle connected to the compression springs.
[0023] Optionally, a guide is provided on the inner wall of the housing, and both ends of the first sealing rod and the second sealing rod are connected to the guide.
[0024] Optionally, a third baffle is provided inside the housing, with the third baffle and the sealing rod located on opposite sides of the slot.
[0025] Optionally, the housing can be injection molded in one piece.
[0026] Optionally, the device also includes a waterproof membrane that wraps around the housing.
[0027] According to a second aspect of the present invention, a waterproofing method for an industrial electronic detonator is also provided, which uses the above-mentioned waterproof tail clamp device to connect the lead wire and conductor of the electronic detonator.
[0028] The waterproof tail wire clamp device and waterproofing method for industrial electronic detonators of the present invention have the following beneficial effects:
[0029] (1) Superior waterproof performance: Through the multiple sealing design of the shell sealed structure, elastic waterproof sealing ring and slot sealing mechanism, a primary and secondary waterproof barrier can be formed to achieve "structural waterproofing" and improve waterproof performance. Thus, it can effectively prevent water from seeping into the connection point in complex environments such as high humidity, high pressure and water immersion. The waterproof performance is significantly better than the traditional grease-injected waterproof structure.
[0030] (2) Simple operation and high safety: During use, the wire can be inserted by pressing the end of the push rod of the slot sealing mechanism to achieve "integrated quick connection". It abandons the traditional flip-top structure, making it more convenient to use, simpler to operate, and with better sealing performance. It is especially suitable for rapid wiring operations in complex environments such as the field and underground, which can greatly reduce the difficulty of operation and time cost, and improve construction efficiency. In addition, the slot sealing mechanism has the advantages of being stable and vibration resistant, which can ensure that the device can work stably under complex working conditions for a long time.
[0031] (3) Stable electrical connection and excellent conductivity: During the sealing process, the slot sealing mechanism can simultaneously drive the blade to cut into the wire sheath and drive the cutting blade to cut into the detonator lead wire sheath, so as to achieve close contact between the wire and the terminal and close contact between the detonator lead wire and the cutting blade. In addition, by continuously applying pressure through the built-in compression spring, it can avoid loosening of the contact due to vibration or temperature changes, ensuring the stability and reliability of signal transmission and circuit conduction, and reducing the risk of duds or accidental explosions.
[0032] (4) Simplified production process and low manufacturing cost: The shell can be made of engineering plastics in one injection molding process, with high structural strength and good sealing performance. It can save the traditional complex processes such as grease injection and bonding, which is convenient for production, reduces manufacturing difficulty and cost, improves production efficiency, and is conducive to realizing mass production, standardization and automation.
[0033] (5) Wide range of applications and high promotion value: This device combines "structural waterproofing" with "integrated quick connection". It has a compact structure, is easy to use, has excellent waterproof, dustproof and anti-corrosion performance, high reliability and long service life. It can be applied to various complex blasting environments such as rainstorms, open air, tunnels and underground, and has good engineering application and promotion value. Attached Figure Description

[0047] Example 1
[0048] like Figures 1-3 As shown, this embodiment discloses a waterproof tail wire clamp device for an industrial electronic detonator, including a housing 1 and a slot sealing mechanism, wherein:
[0049] The housing 1 is a sealed cavity providing a primary seal. The housing 1 is integrally injection molded from high-strength engineering plastic with excellent pressure resistance and waterproof performance, exhibiting good overall pressure resistance and waterproofness. The housing 1 has two parallel lead wire channels and two opposing slots. The lead wire channels are used to insert electronic detonator leads; specifically, the two lead wire channels are used to insert the first detonator lead 1-1 and the second detonator lead 1-2, respectively. The insertion holes of the lead wire channels are equipped with elastic waterproof sealing rings 3, providing a secondary seal. Together with the primary seal formed by the housing 1, they constitute a double-layer protective structure, further improving the sealing and waterproofing system to defend against the risk of water leakage in high humidity, high pressure, or water environments. The slots are located on the outer surface of the housing 1 and are used to place wires; specifically, the two slots are used to place the first wire 2-1 and the second wire 2-2, respectively.
[0050] The slot sealing mechanism is connected to the housing 1 and is used to clamp the wire in the slot and make electrical connection with the electronic detonator lead wire and lock and seal the slot.
[0051] In some embodiments, the elastic waterproof sealing ring 3 is made of materials such as rubber with good elastic recovery and weather resistance, and can maintain its sealing performance after multiple uses.
[0052] In some embodiments, the slot sealing mechanism includes a push rod 6, a central gear 7, a first rack 9, a second rack 8, a sealing rod, a terminal, and a cutting blade, wherein:
[0053] A push rod 6 is inserted through the housing 1, with both ends extending out of the housing 1. A third rack 6-3 is provided on the push rod 6, and the third rack 6-3 is located inside the housing 1. A central gear 7 is located inside the housing 1 and meshes with the third rack 6-3. A first rack 9 and a second rack 8 are symmetrically arranged on both sides of the central gear 7 and mesh with it. The two ends of the sealing rod are slidably mounted on the inner wall of the housing 1. The sealing rod includes a first sealing rod 11-1 and a second sealing rod 11-2. The first sealing rod 11-1 is connected to the first rack 9, and the second sealing rod 11-2 is connected to the second rack 8. A terminal is located inside the housing 1 and is provided with a knife edge. Specifically, there are at least two terminals. The two terminals (referred to as the first terminal 4-1 and the second terminal 4-2) are located on the outside of a slot. When a wire is placed in the slot, each terminal and a sealing rod are located on both sides of the wire in the corresponding slot. The knife edge is preferably V-shaped. The cutting blade is mounted on the push rod and electrically connected to the terminal via a conductive material (such as a copper wire). Specifically, there are at least two cutting blades. The push rod includes a body and a branch 6-4. The branch 6-4 is connected to the body. One cutting blade and the third rack 6-4 are both mounted on the body of the push rod 6, and the other cutting blade is mounted on the branch 6-4 of the push rod 6. The two cutting blades (referred to as the first cutting blade 5-1 and the second cutting blade 5-2, respectively) are located between two lead wire channels, and the cutting edges of the two cutting blades face one lead wire channel respectively. The ends of the cutting blades are preferably V-shaped.
[0054] When one end of push rod 6 is pressed (referred to as the first end 6-1), the third rack 6-3 drives the central gear 7 to rotate and drives the first rack 9 and the second rack 8 to move in opposite directions, thereby driving the first sealing rod 11-1 and the second sealing rod 11-2 to move towards each other (i.e. converge towards the middle) and opening the slot to allow the wire to be placed.
[0055] Subsequently, when the other end of push rod 6 (referred to as the second end 6-2) is pressed, the third rack 6-3 drives the central gear 7 to rotate in the opposite direction, causing the first rack 9 and the second rack 8 to move in opposite directions respectively. This pushes the first sealing rod 11-1 and the second sealing rod 11-2 to move in opposite directions (i.e., to separate towards both ends), causing the wire to be locked in the corresponding slot and achieving slot locking and sealing. At the same time, push rod 6, the first cutting blade 5-1, and the second cutting blade 5-2 are fixedly connected and move as a whole. The first sealing rod 11-1 and the second sealing rod 1-2 push the corresponding wires to the corresponding terminals and cut the wire's outer sheath through the blade on the terminal, thus establishing an electrical connection with the terminal. Push rod 6 drives the corresponding cutting blade to move towards the electronic detonator wire in the corresponding lead wire channel and cuts the outer sheath of the electronic detonator wire, thus establishing an electrical connection with the cutting blade. After cutting, the first electronic detonator wire 1-1 and the first wire 2-1 are electrically connected, and the second electronic detonator wire 1-2 and the second wire 2-2 are electrically connected.
[0056] In some embodiments, the housing 1 has a first baffle inside, with the first baffle and a corresponding cutting blade located on opposite sides of the lead wire channel. Specifically, there are two first baffles, each with a cutting blade on opposite sides of a lead wire channel, i.e., the first baffle is positioned opposite the cutting blade, and the two together form a wire cutting assembly. By setting the first baffle, support can be provided when cutting the outer sheath of the electronic detonator lead wire, preventing the lead wire from moving and affecting the cutting effect.
[0057] In some embodiments, the surfaces of the first sealing rod 11-1 and the second sealing rod 11-2 are provided with sealing reinforcement components. Specifically, the sealing reinforcement components can be rubber waterproof pads or sealing silicone rings, or they can include both rubber waterproof pads and sealing silicone rings. When the rubber waterproof pads are compressed, they form the first sealing barrier, and the sealing silicone rings form the second sealing barrier, ensuring that the slot can be sealed and effectively preventing water from seeping in.
[0058] In some embodiments, both the first sealing rod 11-1 and the second sealing rod 11-2 are equipped with compression springs 10. The housing 1 has a second baffle connected to the corresponding compression spring 10 to prevent loosening after the slots are sealed, ensuring tight contact of the wires. In use, press the first section 6-1 of the push rod 6 to open the two slots, insert the corresponding first wire 2-1 and second wire 2-2, and then press the second end 6-2 of the push rod 6 in the opposite direction to lock and seal the corresponding slots using the first and second sealing rods.
[0059] In some embodiments, a guide member is provided on the inner wall of the housing 1, and both ends of the first sealing rod 11-1 and the second sealing rod 11-2 are connected to the guide member to ensure that the first sealing rod and the second sealing rod can slide stably. Specifically, the guide member can be a guide groove or a guide rail, but is not limited to these.
[0060] In some embodiments, a third baffle is also provided inside the housing 1, with the third baffle and the corresponding sealing rod located on both sides of the slot. Specifically, there are two third baffles, with each third baffle and a sealing rod located on both sides of a slot, which can provide support when cutting the outer sheath of the wire and prevent the wire from moving and affecting the cutting effect.
[0061] In some embodiments, the device of this embodiment further includes a waterproof membrane wrapped around the outer shell 1, particularly covering the opening of the lead wire channel on the shell 1, the mounting location of the push rod 6, and both ends of the push rod 6, thereby further preventing rainwater or mud from entering the internal structure of the shell 1 and enhancing the overall waterproof performance and mechanical strength. Specifically, the waterproof membrane is a high-polymer waterproof plastic film, which is fixed to the shell by hot pressing or ultrasonic welding.
[0062] After actual testing, this device, after being continuously immersed in water at 1.0 MPa pressure for 24 hours, showed no water ingress or signal attenuation at the electronic detonator lead wire connection, achieving an IP68 waterproof performance standard. Furthermore, compared to traditional flip-top structures, assembly time is reduced by approximately 60%, and overall operation is simpler and more reliable.
[0063] The waterproof tail clamp device for the industrial electronic detonator in this embodiment has the following beneficial effects:
[0064] (1) Superior waterproof performance: Through the multiple sealing design of the shell sealed structure, elastic waterproof sealing ring and slot sealing mechanism, a primary and secondary waterproof barrier can be formed to achieve "structural waterproofing" and improve waterproof performance. Thus, it can effectively prevent water from seeping into the connection point in complex environments such as high humidity, high pressure and water immersion. The waterproof performance is significantly better than the traditional grease-injected waterproof structure.
[0065] (2) Simple operation and high safety: During use, the wire can be inserted by pressing the end of the push rod of the slot sealing mechanism to achieve "integrated quick connection". It abandons the traditional flip-top structure, making it more convenient to use, simpler to operate, and with better sealing performance. It is especially suitable for rapid wiring operations in complex environments such as the field and underground, which can greatly reduce the difficulty of operation and time cost, and improve construction efficiency. In addition, the slot sealing mechanism has the advantages of being stable and vibration resistant, which can ensure that the device can work stably under complex working conditions for a long time.
[0066] (3) Stable electrical connection and excellent conductivity: During the sealing process, the slot sealing mechanism can simultaneously drive the blade to cut into the wire sheath and drive the cutting blade to cut into the detonator lead wire sheath, so as to achieve close contact between the wire and the terminal and close contact between the detonator lead wire and the cutting blade. In addition, by continuously applying pressure through the built-in compression spring, it can avoid loosening of the contact due to vibration or temperature changes, ensuring the stability and reliability of signal transmission and circuit conduction, and reducing the risk of duds or accidental explosions.
[0067] (4) Simplified production process and low manufacturing cost: The shell can be made of engineering plastics in one injection molding process, with high structural strength and good sealing performance. It can save the traditional complex processes such as grease injection and bonding, which is convenient for production, reduces manufacturing difficulty and cost, improves production efficiency, and is conducive to realizing mass production, standardization and automation.
[0068] (5) Wide range of applications and high promotion value: This device combines "structural waterproofing" with "integrated quick connection". It has a compact structure, is easy to use, has excellent waterproof, dustproof and anti-corrosion performance, high reliability and long service life. It can be applied to various complex blasting environments such as rainstorms, open air, tunnels and underground, and has good engineering application and promotion value.
[0069] Example 2
[0070] This embodiment discloses a waterproofing method for industrial electronic detonators, which uses the waterproof tail clamp device described in Embodiment 1 above to connect the electronic detonator lead wire and conductor. The specific steps include:
[0071] S1, insert the two detonator leads into the corresponding lead channels on the housing 1 respectively;
[0072] S2, press the first end 6-1 of the push rod 6 to push the first sealing rod 11-1 and the second sealing rod 11-2 towards each other, so that the slot opens and the wire is inserted. Then, press the second end 6-2 of the push rod 6 to push the first sealing rod 11-1 and the second sealing rod 11-2 away from each other, so that the wire is locked in the corresponding slot and the slot is locked and sealed. At the same time, the wire's outer sheath is cut open by the blade on the terminal to make it electrically connected to the terminal. The outer sheath of the electronic detonator lead wire is cut open by the cutting blade to make it electrically connected to the cutting blade. Finally, the connection between the detonator lead wire and the wire is achieved.
[0073] The waterproofing method for industrial electronic detonators in this embodiment, after inserting the detonator leads and conductors, forms a completely water-proof connection environment through the combined action of the internal elastic waterproof sealing ring, the external waterproof membrane, and the sealing rod. Compared to traditional technologies, this avoids the cumbersome operation of flip-top structures and maintains the stability and safety of the circuit connection in water-rich environments. Furthermore, because this method employs the waterproof tail clamp device described in Embodiment 1, it also possesses other effects of this device, which will not be elaborated upon here.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
