[0002] A fault meter detection device is also a multimeter. A multimeter is a multifunctional, multi-range measuring instrument that can measure a variety of electrical parameters, including DC current, DC voltage, AC current, AC voltage, and resistance. The basic principle of a multimeter is to use a sensitive magnetoelectric DC ammeter (microammeter) as a meter head. When a small current passes through the meter head, a current indication is produced. However, since the meter head cannot pass large currents, resistors are connected in parallel or series with the meter head to shunt or reduce the voltage, thereby measuring the current, voltage, and resistance in the circuit.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-5 , the utility model provides a technical solution:

[0037] A fault meter detection device, comprising

[0038] The meter body 2 and the function knob 3 provided on the meter body 2 are used to turn the function knob 3 to align the indicator mark with the item to be tested when voltage, current or resistance is required;

[0039] A power switch 8 is provided on the upper left side of the function knob 3, and a display screen 1 is provided above the power switch 8. The power is turned on by the power switch 8, and data will be displayed on the display screen 1 during detection.

[0040] Below the function knob 3 are arranged sockets 6 arranged in sequence, and the sockets 6 are connected to the sockets 4. The sockets 6 are respectively a current detection socket, a voltage detection socket and a resistance detection socket. The sockets 4 are connected to different holes according to the detection needs.

[0041] When measuring voltage, a measuring circuit is selected that is connected in parallel with the power supply under test. The potential difference of the power supply under test will cause a change in the current in the preselected circuit. The voltage of the power supply is measured and displayed on the multimeter's display 1 through processing and conversion of the components in the measuring circuit.

[0042] When measuring current, the multimeter establishes a low resistance in series with the circuit. When current flows from the power supply under test through this low resistance, a voltage drop proportional to the current is generated. The internal circuit of the multimeter measures the current value based on this voltage drop and displays the result on display 1.

[0043] When measuring resistance, a measuring circuit is selected and connected in series with the resistor to be measured. A known voltage is applied to the circuit, and the resistance value is calculated by measuring the current at that voltage. The result is displayed on display 1.

[0044] In this technical solution, preferably

[0045] One end of the plug connector 4 is connected to a connecting wire 5, and the other end of the connecting wire 5 is connected to a detection pen 7. A protective component is provided on the top of the detection pen 7; a detection pen head 14 is provided on the top of the detection pen 7, and a protective component is sleeved on the outside of the detection pen head 14; the protective component is a protective spring cover 13, and the protective spring cover 13 will shrink when subjected to force;

[0046] There are two detection pens 7 in total, and the two detection pens 7 have the same structure. They are both plugged into the inside of the plug hole 6 through the plug connector 4 connected at the bottom. During the detection process, hold the two detection pens 7, plug the detection pen head 14 into the circuit device of the electric meter that needs to be detected, and then the detection can be carried out. Since a protective spring cover 13 is provided on the outside of the detection pen head 14, when the detection pen head 14 is plugged in for detection, the protective spring cover 13 cannot be inserted due to its large diameter, so it will shrink due to the squeezing force, and the detection pen head 14 will be inserted into the position that needs to be detected for detection. After the detection is completed, the detection pen head 14 is retracted. At this time, there is no external force squeezing, and the protective spring cover 13 will elastically reset and wrap the detection pen head 14 again, thereby forming a protective effect to avoid damage to the detection pen head 14 due to impact when not in use.

[0047] In this technical solution, further, a mounting groove 10 is preferably provided on the back plate of the watch body 2, and a mounting component is provided inside the mounting groove 10;

[0048] The mounting assembly includes a suction cup 9, an adsorption magnet 11 and an adhesive block 12. An adhesive block 12 is provided at the connection between the bottom of the suction cup 9 and the mounting groove 10, and the adhesive connection is performed through the adhesive block 12. An adsorption magnet 11 is embedded in the middle of the suction cup 9. There are four mounting assemblies in total, and the four mounting assemblies are respectively fixed at the four corners of the back plate of the meter body 2. The bottom of the suction cup 9 is connected to the mounting groove 10 by the adhesive block 12. Then, when in use, the suction cup 9 can be used to press and adsorb on a smooth structural surface. It can be adsorbed on different structures such as walls, desktops, and external shells of electric meter boxes as needed. If there is no smooth structure to be adsorbed, the suction cup can also be pressed so that the internal adsorption magnet 11 can be exposed. The adsorption magnet 11 can also be used to magnetically adsorb the device on structures such as metal electric meter boxes, thereby improving the operating performance of the device when in use and freeing up both hands. According to different needs, the device can be held without hand. Moreover, the mounting assembly is embedded in the interior of the mounting groove 10 and does not take up space.

[0049] In this technical solution, further, optionally

[0050] Anti-slip rubber stickers are pasted on the left and right sides of the watch body 2. The anti-slip rubber stickers are adhered to the surface of the watch body 2 using colloid. The surface of the anti-slip rubber stickers is provided with anti-slip grooves. The anti-slip grooves increase the friction between the hand and the watch body, so it is more secure when picking up, avoiding damage caused by the watch body slipping.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
