DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0025] like Figure 1-5As shown, the present invention discloses a mutual inductor polarity check gun 200, which includes a gun body shell 100, a power supply 1, a voltmeter 2, a signal polarity conversion module 3, a remote control signal output module 4, a verification loop sound feedback module 5, an output signal strength adjustment module 6 and a verification loop connection feedback module 7, wherein the voltmeter 2 is connected to both ends of the power supply 1, the power supply 2 is connected to the signal polarity conversion module 3, the remote control signal output module 4 is connected in parallel with the signal polarity conversion module 3, and the output end of the signal polarity conversion module 3 is also connected in sequence with the verification loop sound feedback module 5. Sound feedback module 5, output signal strength adjustment module 6 and verification circuit connection feedback module 7; the output signal strength adjustment module 6 is connected in parallel with the verification circuit connection feedback module 7, and the output signal strength adjustment module 6 is connected in parallel with the verification circuit connection feedback module 7 and then connected in parallel with the verification circuit sound feedback module 6; the power supply 1, voltmeter 2, signal polarity conversion module 3, remote control signal output module 4, verification circuit sound feedback module 5, output signal strength adjustment module 6 and verification circuit connection feedback module 7 are all installed in the gun body shell 100.

[0026] like Figure 5 As shown, the gun body shell 100 includes a left half shell 101 and a right half shell 102, and the left half shell 101 and the right half shell 102 are combined to form the gun body shell.

[0027] The power supply and voltmeter of the present invention are connected to each of the above modules through wires, and the components contained in each of the above modules are connected by wires. The present invention uses the verification loop sound feedback module, the output signal strength adjustment module and the verification loop connection feedback module as loads, so when the loop is connected, the feedback operation includes three senses: light, sound and vibration. The polarity of the internal output of the device is changed by the signal polarity conversion module without changing the wiring. In addition, by operating the remote control signal output module, the output of the forward or reverse polarity signal can also be achieved without operating the gun body trigger. This function is used in a relatively noisy work site. The personnel on the secondary side of the mutual inductor no longer need to order the personnel on the primary side to output the signal. They can use the remote control to perform the signal output operation by themselves, implement the signal themselves, and see the results by themselves. The personnel on the primary side only need to stand by, and after one mutual inductor is completed, the test line is changed to another mutual inductor. Therefore, the operation of the present invention is simpler, and the personnel who cooperate with the operation are reduced, thereby reducing the labor cost. At the same time, the voltage meter can also be used to detect whether the voltage of the power supply is sufficient for verification, thereby ensuring the accuracy of the verification and the professionalism of the measurement results.

[0028] Specifically, it also includes a lighting lamp L1 , which is connected to a downlight switch S2 and is connected in parallel with a power source 1 .

[0029] After adopting the above structure, the present invention can provide the function of on-site lighting, reduce the manpower required for lighting, and improve work efficiency.

[0030] Preferably, the power source 1 is a rechargeable battery with a voltage of 9V. The rechargeable battery is provided with a charging port, so when the battery is low on site, there is no need to disassemble the polarity gun to replace the battery. You only need to connect the matching power bank to charge it. When time is tight, you can check while charging.

[0031] Specifically, the signal polarity conversion module 3 uses a two-way self-resetting switch 30 to connect to the power supply 1 through an "X-type" wiring method. The two-way self-resetting switch 30 has a lever 31 in the middle, which can be moved forward or backward to close the switch. When the lever is released, it automatically returns to the middle to open the switch. In addition, with the X-type connection method, the output of changing polarity can be achieved without changing the wiring.

[0032] Specifically, Figure 3 and 4 As shown, a ring mechanism 32 is sleeved on the switch lever of the two-way self-resetting switch. After the index finger is sleeved into the ring mechanism 32, the forward and reverse outputs can be achieved by simply changing the movement direction of the index finger. Therefore, the present invention can be operated with one hand, and the operation is simpler and more convenient.

[0033] Specifically, the voltmeter 2 is also connected in series with a touch switch S3, which is arranged at the gun handle where it is not easy to be accidentally touched during operation. When the voltage needs to be detected, the switch is pressed to see the voltmeter reading, and the voltage reading disappears when the hand is put down. This not only reduces the buttons on the appearance but also prevents accidental touches and saves power.

[0034] Specifically, the remote control signal output module 4 includes a signal generating remote controller 40 and an electronic opening and closing receiving unit 41 installed in the gun body shell. The signal generating remote controller 40 is wirelessly connected to the electronic opening and closing receiving unit 41, and the electronic opening and closing receiving unit 41 controls the bidirectional self-resetting switch 30.

[0035] Specifically, the signal generating remote controller 40 is provided with an A button and a B button.

[0036] The present invention can output a forward or reverse polarity signal by pressing the A button or the B button on the signal generating remote control without operating the trigger of the gun body. The signal is then received by the electronic opening and closing receiving unit to achieve polarity conversion. Therefore, in a noisy work site, the personnel on the secondary side of the mutual inductor no longer need to order the personnel on the primary side to output the signal. The personnel can use the remote control to perform signal output operations by themselves, send signals by themselves, and view results by themselves. The personnel on the primary side only need to stand by and switch the test line to another mutual inductor after one mutual inductor is completed.

[0037] Specifically, the verification loop sound feedback module 5 includes a polarity correction stack unit 50 and a buzzer 51 . The buzzer 51 is connected to the polarity correction bridge stack unit 50 via a buzzer switch S5 . The polarity correction bridge stack unit 50 is connected to the bidirectional self-resetting switch 30 .

[0038] The polarity correction bridge unit is used to correct the polarity, that is, no matter the A terminal of the buzzer is connected to the positive pole and the B terminal is connected to the negative pole, or the A terminal of the buzzer is connected to the negative pole and the B terminal is connected to the positive pole, the polarity can be corrected through the polarity correction bridge unit so that the electronic device can work normally.

[0039] Specifically, the output signal strength adjustment module 6 and the verification loop connection feedback module 7 are connected to the output end of the bidirectional self-resetting switch 30 through a rotary adjustment switch S4, and the rotary adjustment switch S4 is a four-speed switch.

[0040] By rotating the switch, the mutual inductor of different models can be rotated appropriately, which can effectively save power and avoid the risk of burning out the secondary microammeter. By rotating the adjustment switch, different loads can be connected to each gear, so as to save the consumption of the polarity gun power battery to the maximum extent. When encountering a small ratio test product, the small current and low voltage output can be adjusted to avoid the original practice of using the short-circuit current when the battery is short-circuited every time, which causes the battery power to be consumed quickly.

[0041] Specifically, the output signal strength adjustment module 6 is composed of two oscillators 60 connected in parallel.

[0042] Specifically, the verification loop connection feedback module 7 is composed of a vibrator 60 and an indicator light 70 connected in parallel.

[0043] like Figure 3 , 5 , 6 and 7, the side of the left half shell 101 is provided with a main switch mounting hole 9, a downlight switch mounting hole 10 and a rotary adjustment switch mounting hole 8, the muzzle of the gun body shell 1 is provided with a downlight mounting hole 15, the bottom of the handle of the left half shell 101 is provided with a wiring head mounting hole 13, the side of the right half shell 102 is provided with a buzzer switch hole 16, and the trigger of the gun body shell 100 is provided with a ring mechanism mounting hole 11. The positive output end of the power supply 1 is connected with a main switch S1, the main switch S1 is installed in the main switch mounting hole 9, the downlight switch S2 is installed in the downlight switch mounting hole 10, the rotary adjustment switch S4 is installed in the rotary adjustment switch mounting hole 8, and the buzzer switch S5 is installed in the buzzer switch hole 16. The gun head of the gun body shell is provided with a voltmeter mounting hole 12 and an indicator light mounting hole 17; the bottom of the handle of the right half shell 102 is provided with a charging hole 14 corresponding to the power supply charging, and the handle of the right half shell 102 is provided with a power supply clamp 18 for placing the power supply.

[0044] Implementation:

[0045] like Figure 2 and 3 As shown, perform loop wiring; use a test line to connect the A / P1 wiring hole of the polarity check gun 200 and the P1 terminal of the transformer 400, use a test line to connect the X / P2 wiring hole of the polarity check gun 200 and the P2 terminal of the transformer 400, use a test line to connect the "+" terminal of the microammeter 300 and the 1S1 terminal of the transformer, and use a test line to connect the "-" terminal of the microammeter 300 and the 1S2 terminal of the transformer 400. According to the transformation ratio of the mutual inductance, adjust the switch S4; perform forward verification: press the "main switch" button, then hold the polarity verification gun and put the index finger into the ring trigger and pull it backward or press the A button of the signal generating remote control. If the indicator light of the polarity verification gun 200 is red and accompanied by the buzzer sounding and vibration, it means that the forward voltage has been output normally. At this time, observe the swing direction of the microammeter pointer. If the pointer swings in the positive direction (right), the polarity of the mutual inductance is subtractive polarity. If the pointer swings in the negative direction, it is plus polarity. Perform reverse verification: After determining that the measured mutual inductor 400 is subtractive polarity, push the ring trigger forward or press the B button of the remote control. If the indicator light of the polarity verification gun is green and red and accompanied by the buzzer sounding and vibration, it means that the reverse voltage has been output normally. At this time, the pointer of the microammeter 300 should swing in the opposite direction (left). If the pointer swings to the right, it means that the output of the polarity verification gun 200 is faulty.

[0046] The present invention uses the verification loop sound feedback module, the output signal strength adjustment module and the verification loop connection feedback module as loads, so when the loop is connected, the feedback operation includes three senses: light, sound and vibration; so that the feedback result is clearer, the function is more complete, and it has stronger professionalism. The polarity of the internal output of the device is changed without changing the wiring through the signal polarity conversion module. In addition, by operating the remote control signal output module, the output of the forward or reverse polarity signal can also be achieved without operating the gun body trigger. This function is used in relatively noisy work sites. The personnel on the secondary side of the mutual inductor no longer need to order the personnel on the primary side to output the signal, and can use the remote control to perform the signal output operation by themselves; so the operation is simpler, the number of personnel cooperating with the operation is reduced, and it can be operated with one hand. At the same time, the voltage of the battery can be understood through the voltmeter to ensure that the battery voltage can meet the detection requirements during the detection, thereby ensuring the professionalism and accuracy of the detection results.

[0047] The above are only preferred implementation modes of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. It should be pointed out that for technicians in this technical field, any modification or equivalent replacement of the technical solution of the present invention without creative work does not depart from the protection scope of the technical solution of the present invention.
