Description

Technical Field

[0001] The present application relates to the technical field of electrical measuring equipment, and in particular to inductive electrical measuring equipment. Background Art

[0002] The electrical measuring device is a commonly used electrical measuring tool used to detect whether the object being measured is charged. The conventional electrical measuring device is composed of a head metal body, a high resistor, a tube, a cylinder, a spring and a tail metal body connected in series. When in use, the head metal body contacts the object being measured. If the object being measured is charged, the light-emitting tube in the cylinder emits a bright light to remind the user.

[0003] The inventors have found that although conventional electrical measuring equipment has the advantages of simple structure and low cost, it still has certain disadvantages. For example, conventional electrical measuring equipment requires the user to keep in contact with the tail metal body so that the human body forms a path with the ground, which limits the way the user holds the electrical measuring equipment, making it very inconvenient to use in some situations. There is also a risk that the user does not know that he needs to contact the tail metal body, resulting in the electrical measuring equipment being unable to be used normally. Furthermore, in order to facilitate electrical contact with the object being measured, the head metal body is usually exposed to the outside. If the user touches the head metal body, there is a risk of electric shock. For example, a new type of electrical test pen (publication number CN107328984A) disclosed in the prior art adopts the above-mentioned working form.

[0004] In summary, improving the safety and convenience of electrical measurement by electrical measuring equipment is a technical problem that needs to be solved urgently. Utility Model Content

[0032] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides an inductive electrical measurement device, including a housing 1, a housing 1, an inductive electrical measurement component, and a charged indicator element 4. The housing 1 is made of a transparent material, a PCB board 2 is accommodated in the housing 1, the inductive electrical measurement component is electrically connected to the PCB board 2, and the charged indicator element 4 is attached to the PCB board 2 to indicate whether the object measured by the inductive electrical measurement component is charged.

[0033] The housing 1 is used to install and accommodate various components of the electrical measuring device, so that the housing 1 can protect the components. In addition, the housing 1 can play an insulating and protective role, so that the charged components are isolated from the outside world, which protects the user.

[0034] The housing 1 may be made of plastic, for example, polymethyl methacrylate (commonly known as acrylic material), which has good transparency, weather resistance and mechanical properties. Alternatively, the housing 1 may be made of PVC, which has the advantages of good electrical insulation and light weight.

[0035] PCB is a component used to support and connect electronic components, providing a reliable electrical connection and mechanical structure support between electronic components that need to be connected.

[0036] The inductive electrical measurement component is used to achieve non-contact electrical measurement. Its detailed structure and working principle are well known to those skilled in the art and will not be described in detail here. In general, the inductive electrical measurement component may include an electrical measurement terminal 10 and an amplifier circuit. The amplifier circuit is arranged on the PCB board 2. When the electrical measurement terminal 10 is close to the object to be measured, a weak current is generated at the measurement terminal. After the current is amplified by the amplifier circuit, it can drive other components to work and provide the user with information.

[0037] The charged indicator element 4 may be a light-emitting component, such as an LED lamp, or a sound-emitting component, such as a buzzer.

[0038] The charged indicator element 4 is mounted on the PCB board 2 by surface mounting technology (SMT), which improves the integration of the internal components of the housing 1, making the electrical measuring device thinner and more compact, and improves the connection reliability between the charged indicator element 4 and the PCB board 2.

[0039] The charged indicating element 4 can be electrically connected to the inductive electrical measuring component. For example, in an embodiment where the inductive electrical measuring component includes an amplifier circuit, the charged indicating element 4 is electrically connected to the amplifier circuit, so that the amplifier circuit can drive the charged indicating element 4 to work and prompt the user whether the object being measured is charged.

[0040] Not only the charged indicating element 4 can be attached to the PCB board 2 , but other suitable elements in the housing 1 can also be attached to the PCB board 2 .

[0041] The electrical measuring device in the embodiment of the present application detects whether the object being measured is charged through an inductive electrical measuring component. Compared with traditional electrical measuring devices, on the one hand, it does not require direct contact with the charged object, thereby improving the safety of electrical measurement. On the other hand, there is no requirement for the holding posture of the electrical measuring device when measuring electricity, thereby making the use of the electrical measuring device more convenient.

[0044] The inductive amplifier circuit 7 may include a plurality of transistors 12. The specific circuit connection method of the I-shaped inductor and the transistor 12 combination is well known to those skilled in the art and will not be described in detail here. Figure 4As shown, the I-shaped inductor can be electrically connected to the base of the transistor 12. The current generated by the I-shaped inductor near the object to be measured is amplified by the emitter of the transistor 12, so that the induced current can drive the charged indicator element 4. In order to meet the current amplification requirements, the current amplified by the transistor 12 can continue to be input into the base of the next transistor 12 and amplified by the emitter until the current size is large enough to drive the charged indicator element 4.

[0045] Under the action of the amplifying circuit, the current generated by the electric measuring terminal 10 can be used to drive the charged indicating element 4 to work, so that the charged indicating element 4 can prompt the user whether the measured object is charged.

[0057] The heating indicating element 5 is electrically connected to the PCB board 2 . In an embodiment where the PCB board 2 is provided with a processor, the heating indicating element 5 is electrically connected to the processor.

[0058] The temperature measuring component 9 is used to measure the temperature of the object to be measured, to determine whether the object to be measured has generated heat, and then to determine whether the object to be measured is normal. For example, when the temperature measuring component 9 of the embodiment of the present application is used to detect the wire, if the wire has generated heat, then the wire may have a short circuit.

[0059] When the object being measured generates heat, the heat indicating element 5 can issue a warning, so that the user can pay attention to and handle it in time.

[0060] The way in which the heating indicator element 5 is attached to the PCB board 2 can be the same as the way in which the charged indicator element 4 is attached to the PCB board 2, which, on the one hand, improves the integration of the internal components of the housing 1, making the electrical measuring device thinner and more compact, and on the other hand, improves the connection reliability between the heating indicator element 5 and the PCB board 2.
