Description

Technical Field

[0001] The present invention belongs to the technical field of current and voltage measurement, and in particular relates to an intelligent wireless current and voltage measuring hook meter. Background Art

[0002] Electricity is one of the indispensable energy sources nowadays. When measuring current, most of the practitioners in this field use three-way meters for detection. The instrument that measures physical quantities such as current, voltage, resistance, and power supply electromotive force in the circuit is called an ammeter. Commonly used ones include sensitive ammeter (G meter), ammeter, voltmeter, bridge, potential difference meter, etc. Among them, sensitive ammeters are divided into pointer-type three-way meters and hook-type three-way meters. With the advancement of technology, hook-type three-way meters are more convenient for users to view because of their digital display. Therefore, most practitioners and maintenance personnel now use hook-type three-way meters as the majority. However, although hook-type three-way meters are displayed in digital form for easy viewing by users, However, there is a shortcoming, that is the size problem. Nowadays, the size and space of many circuit settings and instruments are getting smaller and smaller, resulting in the inability of hook-type three-way meters to enter and clamp the circuit to be measured. They can only be used in larger spaces. In view of this, some miniature hook meters have begun to be launched on the market to solve the problem of the previous hook meters being too large. However, this type of hook meter mainly abandons the structure of measuring voltage with probes in exchange for a reduction in size. That is, although the overall size is reduced, the voltage measurement function is also lost. In view of this, it is necessary to continue to develop hook meters that are smaller than traditional hook meters but do not lose the voltage measurement function. This is the direction that the industry needs to work hard in.

[0003] Therefore, it is urgent to design an intelligent wireless current and voltage measurement hook meter to solve the above-mentioned problems. Summary of the Invention

[0018] When the present invention is actually used, it needs to be matched with a mobile device 5, which is wirelessly connected to the circuit board 43 of the measuring assembly. The circuit board 43 further has a built-in transmission unit 431, and the mobile device 5 has a built-in receiving unit 51. The data obtained after the measuring assembly 4 and the magnetic member 22 measure the current of the circuit is transmitted by the transmission unit 431 of the circuit board 43 to the receiving unit 51 of the mobile device 5, and the received current value is viewed on the mobile device 5.

[0019] The aforementioned are the main technical features of the main embodiment of the present invention, which correspond to the content of the first item of the patent application in this case, and can provide a detailed understanding of the purpose and implementation of the present invention. The technical features described in the remaining subsidiary patent applications are detailed descriptions or additional technical features of the content of the first item of the patent application, and are not used to limit the scope of the definition of the first item of the patent application. It should be noted that the first item of the patent application in this case does not necessarily include the technical features described in the remaining subsidiary patent applications.

[0020] According to the above description, in simple terms, before the maintenance person needs to check the line, the first step is to check the electrical properties of the line between points to see if the current of the line is normal and stable. Therefore, the maintenance person rotates the buckle shell 2 relative to the main shell 1 to open it, releases the buckle 24 from the buckle block 14, and then places the line to be measured at the arc slot 13 position, and then rotates the buckle shell 2 relative to the main shell 1 to buckle it so that the buckle 24 can buckle the buckle block 14 again. After completion, the sensing group 41 of the measuring assembly 4 is used to generate an electric field, and the magnetic field between the two magnetic blocks 411 and the magnetic member 22 is used to form an electromagnetic field between the arc slot 13 and the buckle shell 2. The current in the circuit is measured by generating an electromagnetic field, and the result obtained after the measurement is transmitted to the receiving unit 51 of the mobile device 5 through the transmission unit 431 in the circuit board 43. The maintenance person only needs to hold and check the mobile device 5 to know the measured data. Moreover, due to the size limitation of the main shell 1, the present invention can be applied to the current measurement of circuits in small spaces and small volumes, improving the conventional hook-type three-purpose meter, which is not suitable for circuit measurement in small spaces and small volumes. The adjustment, setting, and screen of the conventional hook-type three-purpose meter are all directly set on the body. When operating, the on-site environment must be considered, and there is also the worry that other circuits may be pulled and cause short circuits and other problems.

[0021] According to the above description, other technical features of the present invention are further described in detail. First, the measuring assembly 4 of the present invention is described. The measuring assembly 4 of the present invention has two different implementation types. Please refer to the second figure. The sensing group 41 further includes two side seats 412 and two resistors 414. The two side seats 412 are arranged at intervals on the top of the power component 42, and the two magnetic blocks 411 are respectively arranged on the outer side of each side seat 412. In addition, the two resistors 414 are respectively arranged on each side seat 412, and one end of the two resistors 414 is electrically connected to each other, and the other end of the two resistors 414 is electrically connected to the circuit board 43. The circuit board 43 generates an electric field, and then cooperates with the magnetic field generated between each magnetic block 411 and the magnetic member 22 to generate an electromagnetic field capable of measuring current between the arc slot 13 and the buckle shell member 2. In addition, the second embodiment of the present invention is shown in Figure 7. In addition to the main structure of the sensing group 41 being the same as the above, the two side seats 412 are arranged at intervals at the top of the power member 42 and the coil member 413 is clamped therein, and the two magnetic blocks 411 are respectively arranged on the outer side of each side seat 412. The two magnetic blocks 411 are square, and the two resistors 414 are respectively arranged at one end of each side seat 412, and one end of the two resistors 414 are connected to each other by welding. , the other ends of the two resistors 414 are also electrically connected to the circuit board 43 by welding, and the two ends of the coil 413 are electrically connected to the pins of the two resistors 414, so that the electric field and the magnetic field can be effectively generated, and the current is effectively reduced by the two resistors 414 to prevent the burning of the coil 413, as shown in the second figure; In addition, the power element 42 in the measuring assembly 4 is mainly to provide the operating power source of the circuit board 43, so the power element 42 further includes a battery 421 and a protective base 422, and the protective base 422 is in a U shape and is electrically connected to the circuit board 43, and the protective base 422 and the circuit board 43 A space is formed between the two sides of the protective base 422 to accommodate a battery 421. Two conductive pads 423 are further provided on the top of the protective base 422 toward the circuit board 43. The battery 421 is inserted between the protective base 422 and the circuit board 43, with the positive terminal of the battery 421 contacting the two conductive pads 423, while the negative terminal of the battery 421 electrically contacts a power chip 432 on the circuit board 43. The power chip 432 is primarily etched onto the circuit board 43 and electrically connects to the circuit pattern engraved on the circuit board 43. This allows the battery 421 to supply power to drive the circuit board 43, as shown in the second figure.Furthermore, the circuit board 43 further includes a built-in data conversion unit 433, while the mobile device 5 further includes a built-in recording unit 52. After the buckle housing 2 and the main housing 1 are hooked together to form the circuit to be measured and measurement is performed, the measured power is converted into an electronic signal by the data conversion unit 433 of the circuit board 43. This signal is then transmitted to the receiving unit 51 of the mobile device 5 via the transmission unit 431. The recording unit 52 in the mobile device 5 records each transmission from the transmission unit 431. This allows maintenance personnel to easily access the current data of each circuit in the same location through the mobile device 5, preventing confusion or misjudgment. (See FIG. 4 ).

[0022] and Figure 6 It can also be clearly seen that the measuring head 81 of the voltage sensing component 8 is fixed on the target power line 9. In this way, the circuit board 43 can correctly convert the data measured by the voltage sensing component 8 into a voltage value through the data conversion unit 433, and the transmission unit 431 can transmit the voltage value to the matching mobile device 5. The method of fixing the measuring head 81 to the target power line is further introduced. For example, as shown in Figure 8, one side of the measuring head 81 includes adhesive 811. When in use, only the anti-sticking sticker needs to be removed so that the measuring head 81 can be fixed to the target power line 9 with the adhesive 811, or as shown in Figure 9, the measuring head 81 is set on the side of the arc opening 212 of the outer buckle shell 21. In this way, when the outer buckle shell 21 is buckled, the outer buckle shell 21 will force the measuring head 81 against the target power line 9.

[0023] The voltage sensing component 8 detects voltage spikes based on the electric field coupling method, which is based on the physical properties of electric fields. When voltage is present in a cable or conductor, an electric field is generated around it. The non-contact voltage measurement patch sensor has one or more electrodes. When the sensor is brought close to an electrical conductor, changes in the electric field are sensed and converted into a voltage signal, thereby achieving voltage measurement.

[0024] After explaining the measuring assembly 4, the technical structure is explained. First, in order to allow the two magnetic blocks 411 to be firmly mounted on the two side seats 412, a U-shaped frame 415 is further extended from the side of the two side seats 412 where the two magnetic blocks 411 are mounted. Two slots 417 are formed between each U-shaped frame 415 and each side seat 412, and each magnetic block 411 is respectively mounted in each slot 417 for fixation. In addition, a cone is further protruded from the outer peripheral side of each end of each U-shaped frame 415. Block 416, and the inner wall surface of the accommodating chamber 11 of the main shell 1 further protrudes a plurality of inverted blocks 111 corresponding to the setting of each cone block 416. When the measuring assembly 4 is installed in the accommodating chamber 11, each side seat 412 is connected to the corresponding inverted blocks 111 with each cone block 416 of each ㄩ-shaped frame 415, so that the measuring assembly 4 can be firmly installed in the accommodating chamber 11, preventing the measuring assembly 4 from moving or slipping in the accommodating chamber 11 and affecting the two magnetic blocks 411 and the magnetic member 22. The magnetic field generated between them is shown in the second and third figures; in addition to the above-mentioned plurality of cone blocks 416 and plurality of inverted blocks 111 to prevent the displacement and falling of the measuring assembly 4, a bottom cover 6 is further provided on the bottom of the main housing 1 and closes the accommodating chamber 11. The bottom cover 6 is a square cube, and the bottom of the main housing 1 and at least three inner walls of the accommodating chamber 11 are further provided with a fixing hole 112, and the bottom cover 6 is inserted into the accommodating chamber 11 with one end and has a convex shape corresponding to each fixing hole 112. A plurality of positioning blocks 61 are provided. The bottom cover 6 is mounted on the bottom of the main housing 1 and closes the accommodating chamber 11. The positioning blocks 61 are then snapped into the fixing holes 112 to secure the assembly. One end of the bottom cover 6 is inserted into the accommodating chamber 11, while a baffle 62 extends around the edge of the other end. The baffle 62 abuts against the bottom of the main housing 1. This allows the bottom cover 6 to fit tightly against the main housing 1, thereby preventing foreign matter from entering the accommodating chamber 11 and affecting the operation of the measuring assembly 4. See the first, third, and fourth figures.

[0025] Finally, in order to provide the maintenance personnel with a clear identification of the direction of measurement and prevent the current measurement error, the present invention further provides a direction indicator on the bottom surface of the arc slot 13. Figure 7 , the direction indicates Figure 7Indicates the arrangement direction of the main shell 1 to the circuit to be measured, which is convenient for the maintenance worker to identify the direction of measurement, as shown in the second figure; In addition, in the use of the conventional hook-type three-purpose meter, the maintenance worker must hold the hook-type three-purpose meter for a long time to operate and check it. For the maintenance worker, the generation of electromagnetic waves is easy to cause harm to the body. Another problem is that the hook-type three-purpose meter has a certain volume and weight. If the maintenance worker does not hold it to operate, it is easy to pull other wires and cause circuit breakage, short circuit and other problems. Therefore, in addition to using a limited volume size to meet the measurement of circuits in a small space and a small volume, the present invention further extends a hook at both ends of the arc slot 13. Ribs 16, a hanging groove 17 is formed between each hook rib 16 and the main shell part 1, the main shell part 1 uses the arc groove 13 and the buckle shell part 2 to surround the circuit to be measured, and uses the hanging grooves 17 formed by each hook rib 16 and the main shell part 1 to hook on the adjacent circuit. Because the volume of the present invention is limited, the weight is not as heavy as the conventional ones, so the maintainer can directly hang the present invention on the surrounding circuits with the two hook ribs 16 to prevent the present invention from falling and being damaged, please refer to the first figure; and the mobile device 5 of the present invention can be a smart phone, a laptop computer, a desktop computer, or a tablet, which generally refers to electronic devices that can provide maintenance personnel with viewing, viewing, and operation. They are all the technology to be protected by the present invention, please refer to the sixth figure.

[0026] Taking into account all the technical features described above for the present invention, a maintainer can use the configuration of the present invention to measure line current in a small space and small volume. Moreover, through the wireless link between the circuit board 43 and the mobile device 5, the maintainer does not need to work in a crowded place or hold the device for a long time to obtain the most accurate data. In addition, due to the limited volume of the main shell 1, it is more convenient and easy for the maintainer to carry around, and can quickly measure without making too many settings or adjustments. Compared with the conventional hook-type three-purpose meter, the present invention has improved the shortcomings of the hook-type three-purpose meter, and is obviously more suitable for use by relevant industries, and has a certain degree of progress and practicality.

[0027] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
