Description

Technical Field

[0001] The present invention relates to the technical field of conductive connection, in particular to a leg wire of a split wireless detonator and a manufacturing process thereof. Background Art

[0002] Digital electronic detonators have gradually replaced traditional electric detonators and detonating cords due to their excellent cost-effectiveness and safety. The mainstream electronic detonators currently on the market are wired electronic detonators connected using busbars. Although wired electronic detonators are stable products and mature technology, the blasting construction process is relatively cumbersome. The detonator needs to be connected to a busbar of more than one kilometer, and each detonator needs to be manually clipped to the busbar to form a network. This is not only time-consuming and labor-intensive, but also wastes a lot of wire. Therefore, industrial wireless digital electronic detonators that do not require busbars were born. Each wireless electronic detonator is connected to a transceiver through a two-core iron wire to form a single detonator module. The transceiver communicates with the detonator wirelessly and can also be used to seal blastholes. The wireless electronic detonator is bundled with blasting explosives and placed in the blasthole. The transceiver and the wireless electronic detonator are connected through customized foot wires.

[0003] One of the two-core iron wires serves as a ground wire, while the other is used for both power supply and communication. This requires the detonator module to generate large current negative feedback to achieve data upload. The communication protocol is complex and prone to bit errors. Furthermore, the two-core iron wires are made of iron core wire. The longer the leg of a single-shot detonator module, the significantly increased series line resistance and equivalent capacitance to ground will cause a serious decline in communication quality.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] The present invention provides the following embodiments

[0031] Example 1

[0032] The embodiment of the present invention provides a split type wireless detonator leg line, such as Figure 1-Figure 2As shown, it includes an earphone plug 1, which is connected to a three-core iron wire 3. The end of the three-core iron wire 3 close to the earphone plug 1 is provided with a double-threaded locking terminal 2, and the end of the three-core iron wire 3 away from the earphone plug 1 is provided with a detonator shell rubber plug 4, and the double-threaded locking terminal 2 and the detonator shell rubber plug 4 are fixedly arranged on the outside of the three-core iron wire 3;

[0033] The three-core iron wire 3 includes a power line 301, a data transmission line 302, and a ground line 303. The outgoing end of the power line 301 is welded to the VCC port pad on the wireless detonator module, the outgoing end of the data transmission line 302 is welded to the TRX port pad on the wireless detonator module, and the outgoing end of the ground line 303 is welded to the GND port pad.

[0034] The power line 301 is marked as a red line, the data transmission line 302 is marked as a green line, and the ground line 303 is marked as a black line;

[0035] The headphone plug 1 includes a power segment 101, a suspended segment 102, a data transmission segment 103, and a ground segment 104, which are arranged in sequence from right to left. The power segment 101 is welded to the incoming end of the power line 301, the data transmission segment 103 is welded to the incoming end of the data transmission line 302, and the ground segment 104 is welded to the incoming end of the ground line 303.

[0036] The earphone plug 1 is plugged into the socket on the transceiver, and the detonator shell rubber plug 4 is connected to the wireless detonator module.

[0037] The beneficial effects of the above technical solution are:

[0038] The headphone plug 1 is a four-section headphone interface that plugs into the receptacle on the transceiver for easy insertion and removal, and is waterproof, dustproof, and shockproof. The double-threaded locking terminal 2 can be double-threadedly connected to the transceiver's housing to increase the load-bearing capacity of the three-core iron wire 3, allowing it to suspend heavy explosives. The headphone plug 1 includes, from right to left, a power section 101, a suspended section 102, a data transmission section 103, and a ground section 104. The suspended section 102 isolates the power section 101 from the data transmission section 103, preventing high voltage on the power line 301 from contacting the data transmission line 302 during insertion and removal of the headphone plug 1, thereby damaging the communication port.

[0039] The transceiver provides the wireless detonator module with an operating voltage through the power line 301. The transceiver is designed with a voltage regulation circuit. When the module is in a low-power communication state, the power line 301 is at a low voltage; when the wireless detonator module is in a charging state waiting for detonation, the power line 301 is at a high voltage.

[0040] The data transmission line 302 is a single-line half-duplex serial port, used to implement uplink and downlink data communication between the transceiver MCU and the wireless detonator module MCU. By adding a small number of discrete electronic components, the standard two-line TTL serial port can be converted into a single-line TTL half-duplex serial port. The transceiver MCU and the wireless detonator module MCU support TTL hardware serial ports, and the protocol is standard and reliable. Communication can be achieved without additional development, reducing the complexity of the communication protocol. In addition, the TTL serial port has a large judgment margin for high and low level signals, and the influence of the line resistance and equivalent capacitance on the communication quality can be ignored, and it can support longer line lengths.

[0041] The power line 301 is marked as a red line, the data transmission line 302 is marked as a green line, and the ground line 303 is marked as a black line, which makes it easy to distinguish each core line in the three-core iron wire 3. Compared with the two-core iron wire, the three-core iron wire 3 separates the power line 301 from the data transmission line 302. The power line 301 is used for power supply, and the data transmission line 302 is used for communication. The power supply and communication are separated, which not only ensures the stability of communication, but also solves the above-mentioned technical problem that the two-core iron wire is used for simultaneous power supply and communication, and a large current negative feedback is required at the detonator module end to realize data upload, and its communication protocol is complex and prone to bit errors. It can also ensure that the communication quality is not affected by the length of the leg line, and solves the technical problem that the material of the two-core iron wire is iron core wire, the longer the leg line of the single-shot detonator module is, the more its series line resistance and equivalent capacitance to the ground will increase significantly, which seriously reduces the communication quality.

[0042] Example 2

[0043] On the basis of Example 1, Figure 1-Figure 3 As shown, a manufacturing process for the leg wire of a split wireless detonator includes the following steps:

[0044] Step 1: Processing the three-core iron wire 3: Cut the bundled three-core iron wire 3 into the target length, peel off the insulation sheaths at both ends of the cut three-core iron wire 3, and dip the exposed ends of the three-core iron wire 3 into tin;

[0045] Step 2: Conduct a connectivity test on the three-core iron wire 3 after tinning;

[0046] Step 3: Welding the headphone plug 1: Weld the qualified three-core iron wire 3 to the headphone plug 1 to obtain a semi-finished foot wire;

[0047] Step 4: Test the connectivity of the semi-finished cable.

[0048] Step 5: Low-temperature injection molding: The two ends of the semi-finished leg wire that have passed the test are subjected to low-temperature injection molding to form a double-threaded locking terminal 2 and a detonator shell rubber plug 4;

[0049] Step 6: Conduct a connectivity test on the semi-finished baseboard after low-temperature injection molding, and obtain the finished baseboard after passing the test;

[0050] The specific steps of step 1 are: using a wire cutting machine to cut the bundled three-core iron wire 3 into a target length, then using a wire stripping machine to peel off the insulation sheaths at both ends of the cut three-core iron wire 3 to expose part of the wire ends, and finally placing the exposed wire ends of the three-core iron wire 3 into a tin furnace to dip in tin.

[0051] The beneficial effects of the above technical solution are:

[0052] The connectivity test in steps 2, 4, and 6 can be performed using a multimeter. Set the multimeter to the ohm range and place the test pen at both ends of each core wire of the three-core iron wire 3. If the buzzer sounds, it indicates that the three-core iron wire 3 is connected and the process continues to the next step. If the buzzer does not sound, the wire is scrapped. The wire cutting machine and wire stripping machine used in step 1 are both existing equipment. The low-temperature injection molding adopts the existing process, and the low-temperature injection molding material is PVC.

[0053] Example 3

[0054] On the basis of Example 2, Figure 4-Figure 5 As shown, the connectivity tests of step 2, step 4 and step 6 can also be tested with an automatic testing device, which includes a shell 6, a test inlet 8 provided at the upper end of the shell 6, a cavity 7 provided inside the shell 6, and a qualified outlet 9 and an unqualified outlet 10 provided at the lower end of the shell 6. The qualified outlet 9 and the unqualified outlet 10 are distributed left and right, and the test inlet 8, the cavity 7 and the qualified outlet 9 or the unqualified outlet 10 are connected in sequence from top to bottom. A motor is fixedly provided at the front end of the shell 6, and the motor is fixedly connected to the motor shaft 12. The motor shaft 12 passes through the front end of the shell 6 into the cavity 7 and is fixedly connected to the positioning sleeve 11. A matching groove 13 is provided at the upper end of the positioning sleeve 11, and the lower end of the matching groove 13 is connected to the test slot 14. The side ends of the test slot 14 are provided with a ground wire test terminal 15, a data transmission line test terminal 16 and a power line test terminal 17 in sequence from top to bottom, and the matching groove 13 is arranged corresponding to the head positioning mechanism.

[0055] The beneficial effects of the above technical solution are:

[0056] The three-core iron wire 3 to be tested can be placed into the head positioning mechanism from the test inlet 8. The core wires of the three-core iron wire 3 include a power line 301, a data transmission line 302 and a ground line 303. The test parts of the heads of the core wires of the three-core iron wire 3 are fixed, and then the head positioning mechanism is moved into the matching groove 13. Then the motor is controlled to work, the motor drives the motor shaft 12 to rotate, the motor shaft 12 drives the positioning sleeve 11 to rotate, and the positioning sleeve 11 drives the three-core iron wire 3 to be wound around the positioning sleeve 11, so that the three-core iron wire 3 enters the cavity 7 to avoid the three-core iron wire 3 from entering the cavity 7. The core iron wire 3 is too long, making the connectivity test inconvenient. After the test parts of the tail of each core wire of the three-core iron wire 3 enter the test inlet 8, the tail of each core wire of the three-core iron wire 3 is energized. If the heads of each core wire of the three-core iron wire 3 are conductive, the three-core iron wire 3 is output from the qualified outlet 9. If any of the core wire heads of the three-core iron wire 3 is not conductive, the three-core iron wire 3 is output from the unqualified outlet 10. The three-core iron wire 3 can be automatically tested for connectivity and classified, thereby improving the test efficiency of the three-core iron wire 3 and facilitating standardized testing.

[0057] Example 4

[0058] On the basis of Example 3, Figure 4-Figure 5 As shown, the head positioning mechanism includes a mounting plate 31 corresponding to the test inlet 8, contact blocks are symmetrically provided at the left and right ends of the mounting plate 31, contact switches are symmetrically provided at the left and right ends of the matching groove 13, the contact blocks and the contact switches are in corresponding contact, springs 35 are symmetrically provided between the left and right ends of the mounting plate 31 and the matching groove 13, connecting blocks 39 are symmetrically provided on the left and right sides of the mounting plate 31, and the straight ends of the connecting blocks 39 are slidably connected to the mounting plate 31, the straight ends of the connecting blocks 39 are fixedly connected to the fixing plate 36, a spring 37 is fixedly provided between the fixing plate 36 and the left and right sides of the mounting plate 31, the middle part of the fixing plate 36 is slidably connected to the socket 32, the lower end of the socket 32 ​​is fixedly connected to the electric telescopic rod 40, the electric telescopic rod 40 is fixedly set in the positioning sleeve 11, the upper end of the socket 32 ​​is provided with a socket 33, the socket 33 A power line test portion 41 is provided at the lower end, a data transmission line test portion 42 is provided at the middle side end of the jack 33, a ground line test portion 43 is provided at the upper side end of the jack 33, the socket 32 ​​corresponds to the test slot 14, and a limit plate 34 is fixedly provided at the upper end of the socket 32, which corresponds to the limit hole 35 set through the middle part of the mounting plate 31, the inclined end of the connecting block 39 is slidably connected to the upper inclined end of the clamping block 38, and the lower inclined end of the clamping block 38 is in contact with the limit plate 34, and sliding grooves 24 are symmetrically provided at the left and right ends of the lower side of the test inlet 8, and a sliding block 27 is slidably provided in the sliding groove 24, and a spring 26 is fixed between the sliding block 27 and the sliding groove 24, and the end of the sliding block 27 away from the spring 26 is rotatably connected to the guide wheel 28, and a distance measuring sensor 25 is fixed at the side end of the sliding groove 24.

[0059] The beneficial effects of the above technical solution are:

[0060] After the ends of the three-core iron wires 3 are inserted into the jack 33, the end of the power cord 301 is inserted into the hole opened in the power cord test section 41, the end of the data transmission line 302 is inserted into the hole opened in the data transmission line test section 42, and the end of the ground wire 303 is inserted into the hole opened in the ground wire test section 43, so that the power cord 301 is connected to the power cord test section 41, the data transmission line 302 is connected to the data transmission line test section 42, and the ground wire 303 is connected to the ground wire test section 43. If the headphone plug 1 is welded to the three-core iron wire 3 and the headphone plug 1 is inserted into the jack 33, the power segment 101 of the headphone plug 1 can be attached to and connected with the power cord test section 41, the data transmission segment 103 of the headphone plug 1 can be attached to and connected with the data transmission line test section 42, and the ground segment 104 of the headphone plug 1 can be attached to and connected with the ground wire test section 43;

[0061] After the ends of the core wires of the three-core iron wire 3 or the headphone plug 1 are connected to the socket 32, the three-core iron wire 3 is pressed toward the direction of the cavity 7, and the electric telescopic rod 1 40 is operated. When the electric telescopic rod 1 40 is operated, the socket 32 ​​is driven to move toward the direction of the matching groove 13 to ensure that the ends of the core wires of the three-core iron wire 3 or the headphone plug 1 are always connected to the socket 32. Under the elastic action of the spring 3 5 and the spring 1 37, the mounting plate 31 and the fixing plate 36 are in a stationary state. The socket 32 ​​slides along the fixing plate 36. The socket 32 ​​drives the limiting plate 34 to extend into the limiting hole 35 until the limiting plate 34 extends out of the limiting hole 35 and contacts the fixing plate 36, driving the fixing plate 36 to move. The fixing plate 36 drives the spring 1 37 to stretch, and the fixing plate 36 drives the connecting block 39 to slide along the mounting plate 31. When the connecting block 39 slides, it drives the clamping block 38 to move in the direction of approaching each other. After the lower inclined section of 8 contacts the limit plate 34, it can assist in pushing the limit plate 34 into the limit hole 35 until the limit plate 34 is completely in the limit hole 35, and the clamping block 38 positions and contacts the three-core iron wire 3 to prevent the three-core iron wire 3 from being out of contact with the socket 32. The clamping block 38 is an elastic block that can squeeze and position three-core iron wires 3 or double-threaded locking terminals 2 of different diameters. At this time, the connecting block 39 cannot slide along the mounting plate 31, and the socket 32 ​​begins to drive the mounting plate 31 to move toward the matching groove 13 until the mounting plate 31 enters the matching groove 13. The spring three 5 is compressed, and the socket 32 ​​extends out of the fixing plate 36. At this time, the socket 32 ​​cooperates with the test slot 14, so that the power line test part 41 is connected to the power line test terminal 17, the data transmission line test part 42 is connected to the data transmission line test terminal 16, and the ground line test part 43 is connected to the ground line test terminal 15.

[0062] After the mounting plate 31 is matched with the matching groove 13, the motor shaft 12 drives the positioning sleeve 11 to rotate. Since the mounting plate 31 is separated from the test inlet 8, the sliding block 27 is pushed toward the test inlet 8 under the elastic action of the spring 26 in the compressed state. The sliding block 27 drives the guide wheel 28 to move. The guide wheel 28 positions and contacts the three-core iron wire 3, and plays a guiding role when the three-core iron wire 3 moves toward the cavity 7, ensuring that the process of winding the three-core iron wire 3 when the positioning sleeve 11 rotates remains smooth. When the tail of the three-core iron wire 3 passes through the test inlet 8, the three-core iron wire 3 is rotated. When the insulation coating is stripped off from the tail of the three-core iron wire 3, its diameter changes. Under the elastic action of the second spring 26, the guide wheel 28 continues to move to position and contact the tail. The distance sensor 25 is used to detect the distance between the sliding block 27 and the side end of the sliding groove 24. When the distance detected by the distance sensor 25 reaches the target range, that is, the theoretical distance between the sliding block 27 and the side end of the sliding groove 24 after the guide wheel 28 contacts the tail of the core of the three-core iron wire 3, the tail of the core of the three-core iron wire 3 is positioned and contacted, and power is applied to perform a connectivity test.

[0064] On the basis of Example 4, Figure 4-Figure 5 As shown, the left and right ends of the upper side of the test inlet 8 are symmetrically provided with power blocks 30, the power blocks 30 are fixedly connected to the electric telescopic rod 29, the electric telescopic rod 29 is fixedly arranged inside the shell 6, the side end of the qualified outlet 9 is provided with a camera 18, the outlet of the qualified outlet 9 is provided with a baffle 1 20, the baffle 1 20 is fixedly connected to the electric telescopic rod 3 19, the side end of the unqualified outlet 10 is provided with a camera 21, the outlet of the unqualified outlet 10 is provided with a baffle 23, the baffle 23 is fixedly connected to the electric telescopic rod 4 22, the electric telescopic The retractable rod 3 19 and the electric telescopic rod 4 22 are fixedly arranged inside the shell 6, and the ground wire test terminal 15, the data transmission line test terminal 16 and the power line test terminal 17 are respectively electrically connected to the electric telescopic rod 3 19, the electric telescopic rod 4 22 and the motor through the controller 1, the camera 1 18 is electrically connected to the motor through the controller 2, the camera 21 is electrically connected to the motor through the controller 3, the ranging sensor 25 is respectively electrically connected to the electric telescopic rod 2 29, the power block 30 and the motor through the controller 4, and the contact switch is electrically connected to the motor through the controller 5.

[0065] The beneficial effects of the above technical solution are:

[0066] After the distance detected by the distance measuring sensor 25 reaches the target range, the distance measuring sensor 25 controls the electric telescopic rod 29 to extend and retract through the controller 4, and energizes the power block 30, the motor stops working, and the electric telescopic rod 29 drives the power block 30 to contact and position the tail of the core wire of the three-core iron wire 3, and the power block 30 energizes the tail of the core wire of the three-core iron wire 3. If the core wires of the three-core iron wire 3 are all connected, the power line test part 41 is conductive to the power line test end 17, the data transmission line test part 42 is conductive to the data transmission line test end 16, and the ground line test part 43 is conductive to the ground line test end 15. After the ground line test end 15, the data transmission line test end 16 and the power line test end 17 are all conductive, the three are controlled by the controller 1. The electric telescopic rod 3 19 is retracted, and the motor continues to work. The electric telescopic rod 3 19 drives the baffle 1 20 to retract, and no longer blocks the qualified outlet 9. The motor shaft 12 drives the positioning sleeve 11 to continue to rotate, so that the core wire tail of the three-core iron wire 3 enters the cavity 7. Since the core wire tail of the three-core iron wire 3 is not fixed, the core wire tail of the three-core iron wire 3 rotates to the qualified outlet 9. At this time, the camera 18 of the qualified outlet 9 captures the image of the three-core iron wire 3, that is, after the core wire tail of the three-core iron wire 3 is in the qualified outlet 9, the camera 18 controls the motor to work in the reverse direction through the controller 2, so that the three-core iron wire 3 passes through the qualified outlet 9 and gradually loosens the positioning sleeve 11, completing the automatic detection and classification of the three-core iron wire 3;

[0067] After the mounting plate 31 is matched with the matching groove 13, the contact block contacts the contact switch, and the contact switch controls the motor to work through the controller 5. The motor drives the motor shaft 12 to rotate. When any of the ground wire test terminal 15, the data transmission line test terminal 16 and the power line test terminal 17 is not conductive, the three together control the electric telescopic rod 4 22 to retract through the controller 1, and the motor continues to work. The electric telescopic rod 4 22 drives the baffle 2 23 to retract. The baffle 23 no longer blocks the unqualified outlet 10, and the motor shaft 12 drives the positioning sleeve 11 to continue to rotate. The tail of the core wire of the three-core iron wire 3 moves so that the tail of the core wire of the three-core iron wire 3 enters the cavity 7. Since the tail of the core wire of the three-core iron wire 3 is not fixed, after the tail of the core wire of the three-core iron wire 3 rotates to the unqualified outlet 10, the second camera 21 of the unqualified outlet 10 captures the image of the three-core iron wire 3. That is, after the tail of the core wire of the three-core iron wire 3 is present at the unqualified outlet 10, the second camera 21 controls the motor to work in the reverse direction through the third controller, so that the three-core iron wire 3 passes through the qualified outlet 9 and gradually loosens the positioning sleeve 11, thereby completing the automatic detection and classification of the three-core iron wire 3.

[0068] After the connectivity test is completed and the three-core iron wire 3 in the cavity 7 is discharged from the qualified outlet 9 or the unqualified outlet 10, a spirit level is installed in the matching slot 13. If the spirit level detects that it is level and the matching slot 13 is open upward, it means that the mounting plate 31 corresponds to the test inlet 8. At this time, the electric telescopic rod 29, the electric telescopic rod 31, the electric telescopic rod 42 and the electric telescopic rod 10 are controlled to return to their original positions. The electric telescopic rod 10 drives the socket 32 ​​to disengage from the test slot 14 until the socket 32 ​​can no longer move along the fixing plate 36. The mounting plate 31 is disengaged from the mating groove 13 by the elastic action of the spring 37, and the mounting plate 31 re-enters the test inlet 8. The lower end of the sliding block 27 can be provided with an inclined section, so that after the mounting plate 31 enters the test inlet 8, the sliding block 27 and the guide wheel 28 enter the sliding groove 24, so that the mounting plate 31, the sleeve 32, the baffle 1 20 and the baffle 23 return to their original positions.

[0069] The above-mentioned camera 1 18, camera 2 21, ranging sensor 25, contact switch, power block 30, electric telescopic rod 2 29, electric telescopic rod 3 19, electric telescopic rod 4 22, motor, controller 1, controller 2, controller 3, controller 4 and controller 5 all adopt existing equipment, and the signal transmission and control technology between the above-mentioned components all adopt existing technology. The ground wire test terminal 15, the data transmission line test terminal 16 and the power line test terminal 17 are equivalent to switches. All three are energized through the controller 1 to start the electric telescopic rod 3 19 and the motor. If any of the three test terminals is not energized, the electric telescopic rod 4 22 and the motor are turned on. The above-mentioned control method adopts existing technology and will not be repeated in detail in the present invention. Optionally, a traction manipulator can be set at the qualified outlet 9 and the unqualified outlet 10 to facilitate pulling out the three-core iron wire 3 after the connectivity test is completed.
