Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical testing technology, and in particular to an electrical testing device. Background Technology
[0002] In the field of power testing, voltage detectors are crucial tools for ensuring personnel safety and the normal operation of power systems. However, existing voltage detectors have many limitations in practical use.
[0003] Traditional voltage detectors mostly use a straight-rod induction probe design. When performing voltage detection operations at heights or over long distances, operators must hold the probe for extended periods, making the operation difficult and labor-intensive. Moreover, in confined spaces or complex voltage detection environments with obstacles, the straight-rod probe cannot penetrate or bypass obstacles for detection, thus limiting the voltage detection work.
[0004] Regarding detection accuracy, the contact area between the straight probe and the charged body is limited. When the surface of the charged body is uneven, oily, or dusty, poor contact can easily occur, affecting the charge induction effect and thus reducing the accuracy of voltage detection. At the same time, this type of probe has poor adaptability to the electric field distribution around the charged body and is easily affected by external electric field interference, leading to misjudgments. Summary of the Invention
[0005] The main purpose of this invention is to provide an electrical testing device that aims to improve the accuracy of testing.
[0006] To achieve the above objectives, the present invention proposes an electrical testing device, which includes an electrical testing component and a holding component, wherein the electrical testing component is connected to the holding component;
[0007] The voltage detection component includes a voltage detection body and a voltage detection contact terminal, and the voltage detection contact terminal includes a first induction probe and a second induction probe.
[0008] The free end of the first sensing probe extends outward along the length of the voltage testing body, and the second sensing probe extends outward in an arc shape from the voltage testing body, with the free end of the second sensing probe facing the side of the voltage testing body.
[0009] In some embodiments of this utility model, the voltage testing device further includes a telescopic member, which is connected to the gripping member; the telescopic member enables the voltage testing member to move closer to or further away from the gripping member.
[0010] In some embodiments of this utility model, the telescopic member is a telescopic rod, and the end of the holding member facing the voltage testing member is provided with a receiving cavity, which is used to accommodate the retracted telescopic rod. The end of the voltage testing member near the holding member can be fitted and fixed with the holding member.
[0011] In some embodiments of this utility model, the voltage testing device further includes an illumination component, which is disposed on the holding component;
[0012] The lighting component includes a lamp body and an adjustment mechanism, which can adjust the illumination direction of the lamp body.
[0013] In some embodiments of this utility model, the adjustment mechanism includes an adjustment ring, and the lamp body is fixed on the adjustment ring; the gripping member is provided with a groove for the adjustment ring to be nested in, the inner side of the adjustment ring is provided with a pawl, and the groove is provided with teeth that cooperate with the pawl.
[0014] In some embodiments of this utility model, the lamp body is hinged to the adjusting ring, the lamp body can be adjusted and rotated around the hinge position of the adjusting ring, and the gripping member has a cavity on one side of the adjusting ring for accommodating the lamp body.
[0015] In some embodiments of this utility model, an insulating rubber ring is provided on the side of the holding member close to the voltage testing member.
[0016] In some embodiments of this utility model, the voltage detection component is equipped with an alarm light.
[0017] This invention employs a second sensing probe with a curved design, making it easy to attach to various charged conductors and equipment. This eliminates the need for prolonged handheld use, reducing the difficulty and intensity of high-altitude or long-distance voltage testing operations. Furthermore, it can penetrate narrow spaces, bypass obstacles, and adapt to complex environments.

[0027] See appendix Figure 1-2 The present invention proposes an electrical testing device, which includes an electrical testing component 100 and a holding component 200, wherein the electrical testing component 100 and the holding component 200 are connected.
[0028] The voltage detection component 100 includes a voltage detection body 110 and a voltage detection contact terminal, the voltage detection contact terminal including a first induction probe 120 and a second induction probe 130.
[0029] The free end of the first sensing probe 120 extends outward along the length of the voltage testing body 110, and the second sensing probe 130 extends outward in an arc shape from the voltage testing body 110, with the free end of the second sensing probe 130 facing the side of the voltage testing body 110.
[0030] Based on the aforementioned technical features, the free end of the first sensing probe 120 extends outward along the length of the voltage testing body 110. This design allows for convenient contact with the object being tested in conventional voltage testing scenarios, especially for flat surfaces or easily accessible conductors. Its straight extension allows operators to accurately align the probe with the target position, improving the accuracy and efficiency of voltage testing. The curved design of the second sensing probe 130 facilitates hanging on various charged conductors and equipment, eliminating the need for prolonged handheld use, reducing the difficulty and intensity of high-altitude or long-distance voltage testing operations, and enabling it to penetrate narrow spaces, bypass obstacles, and adapt to complex environments. Furthermore, due to its curved design, it has a large contact area with the charged body, allowing for sufficient charge sensing even on surfaces with poor conditions. This allows it to better adapt to the electric field distribution around the charged body, making it easier to capture electric field signals and reducing the impact of external electric field interference on the voltage testing results, thereby more accurately detecting the charge status of the charged body.
[0031] Furthermore, the voltage testing device also includes a telescopic member 300, through which the voltage testing member 100 is connected to the holding member 200; the telescopic member 300 enables the voltage testing member 100 to move closer to or further away from the holding member 200.
[0032] In this embodiment, the telescopic member 300 is a telescopic rod, and the end of the holding member 200 facing the voltage testing member 100 is provided with a receiving cavity for accommodating the retracted telescopic rod. The end of the voltage testing member 100 near the holding member 200 can be fitted and fixed with the holding member 200, thus enhancing the flexibility and portability of the voltage testing device. When long-distance voltage testing is not required, the telescopic rod can be retracted into the receiving cavity, shortening the overall length of the device for easy carrying and storage. When it is necessary to detect live conductors at higher positions or at greater distances, the telescopic rod can be extended to increase the distance between the voltage testing member 100 and the holding member 200, allowing operators to perform voltage testing operations from a safe distance, effectively ensuring the safety of the operators.
[0033] The voltage testing device also includes an illumination component 400, which is disposed on the holding component 200;
[0034] The lighting component 400 includes a lamp body 420 and an adjustment mechanism, which can adjust the illumination direction of the lamp body 420.
[0035] Specifically, the adjustment mechanism includes an adjustment ring 410, on which the lamp body 420 is fixed. The gripping member 200 is provided with a groove for the adjustment ring 410 to nest in. A pawl is provided on the inner side of the adjustment ring 410, and teeth are provided in the groove to engage with the pawl. Through the engagement of the pawl and the teeth, the illumination angle of the lamp body 420 can be finely adjusted and has a self-locking function. After adjusting to a suitable illumination angle, the pawl will lock into the teeth, preventing the lamp body 420 from rotating arbitrarily due to external force or vibration, ensuring the stability of the illumination direction during the voltage testing process, and providing stable lighting conditions for the voltage testing operation.
[0036] Furthermore, the lamp body 420 is hinged to the adjusting ring 410, allowing the lamp body 420 to rotate around the hinged position of the adjusting ring 410. The holding member 200 has a cavity on one side of the adjusting ring 410 to accommodate the lamp body 420, further increasing the flexibility of the lighting. Operators can not only adjust the overall lighting direction using the adjusting ring 410, but also rotate the lamp body 420 individually to meet lighting needs at different angles and positions. When not in use, the lamp body 420 can be rotated and stored inside the cavity to prevent damage from impacts, while also making the device more compact.
[0037] An insulating rubber ring 500 is provided on the side of the gripping component 200 near the voltage testing component 100. The insulating rubber ring 500 can further enhance the insulation performance of the voltage testing device, prevent the current from being conducted to the operator's hand through the gripping component 200 during the voltage testing process, provide additional safety protection for the operator, and reduce the risk of electric shock.
[0038] Specifically, the voltage testing component 100 is equipped with an alarm light 600. Compared with a simple sound alarm, the light alarm can more intuitively inform the operator of the voltage testing results in noisy environments or when visibility is obstructed, so as to take appropriate safety measures in a timely manner and improve the safety and reliability of voltage testing operations.
[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
