Description

Technical Field

[0001] This utility model relates to the field of electrical measurement and protection technology, and in particular to an electrical and electronic electrical measurement device with an anti-accidental contact protection structure. Background Technology

[0002] Currently, electrical and electronic measuring devices are mainly used to detect whether there is voltage in wires, electrical appliances or circuits. They usually detect electrical signals by using a test pen or test rod and indicate this by illuminating an indicator light.

[0003] Traditional voltage testing devices mostly use a fixed indicator light mode. When the voltage testing rod touches a live conductor, the indicator light will light up under the action of a weak current. The brightness of the indicator light in existing equipment is fixed, and it is impossible to distinguish the indication based on the strength of voltage or current, making it difficult for users to intuitively judge the voltage strength. Utility Model Content

[0004] The main objective of this invention is to provide an electrical and electronic measuring device with an anti-accidental contact protection structure, aiming to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model proposes an electrical and electronic measuring device with an anti-accidental contact protection structure, comprising a handle, an arc protection cover fixedly mounted on one side of the handle, a measuring rod fixedly mounted on the inner wall of the arc protection cover, an insulating sleeve fixedly mounted on the outer side of the measuring rod, and the other side of the measuring rod extending into the cavity of the handle with its top end forming a circular plane, on one side of which a Y-shaped conductive rod is fixedly mounted.

[0006] In one embodiment, the conductive rod is arranged horizontally, with contacts at both its upper and lower ends. An indicator light is fixedly installed on the top of the upper contact, and the indicator light is fixedly installed in a mounting groove on one side of the handle.

[0007] In one embodiment, a spring is fixedly installed on the bottom surface of the center position of the conductive rod, and a button is fixedly installed on the top surface on the side opposite to the spring.

[0008] In one embodiment, a spring is fixedly provided on the upper side of the button, and both the spring and the button are movably installed in the housing on one side of the handle.

[0009] In one embodiment, a conductive plate is disposed at intervals in the cavity of the handle below the lower end contact of the conductive rod.

[0010] In one embodiment, the conductive plate has a rectangular structure, with a connector on one side that matches the lower end contact of the conductive rod, and a neon bulb fixedly installed on the top surface of the other side, with the top of the neon bulb fixedly installed in a preset mounting port on one side of the handle.

[0011] Beneficial effects: An insulating sleeve is installed on the pole body in the contact area of ​​the test pole, which can effectively isolate the conductive parts and only expose the top part of the test pole. This facilitates full contact between the operating end and the power source under test, and prevents the operator from accidentally touching the conductor during the test and causing electric shock. The safety is significantly improved. An arc protection shield is installed outside the insulating sleeve to form a double-layer protection structure, which can completely isolate the arc sputtering during the test and prevent burns and equipment damage.

[0012] In addition, the device has a dual indication function. A weak current passing through the conductive rod can light up the indicator light for preliminary detection of leakage. When the button is pressed to make the conductive rod and the conductive plate conduct electricity, a stronger voltage can light up the neon bulb, making it easier for the operator to distinguish the leakage level and degree of danger, thus enhancing the safety, intuitiveness and practicality of use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To achieve the above-mentioned utility model objectives, such as Figure 1-4As shown, this utility model provides an electrical and electronic measuring device with an anti-accidental contact protection structure, including a handle 1. An arc protection cover 2 is fixedly installed on one side of the handle 1. A measuring rod 3 is fixedly installed on the inner wall of the arc protection cover 2. An insulating sleeve 4 is fixedly installed on the outer side of the measuring rod 3. The other side of the measuring rod 3 extends into the cavity of the handle 1 and its top end is a circular plane. A Y-shaped conductive rod 8 is fixedly installed on one side of this plane. The conductive rod 8 is arranged horizontally and has contacts at both its upper and lower ends. An indicator light 6 is fixedly installed on the top of the upper contact. The handle 1 is installed in a mounting slot on one side; a spring 9 is fixedly installed on the bottom surface of the center position of the conductive rod 8, and a button 5 is fixedly installed on the top surface of the side opposite to the spring 9; a spring piece is fixedly installed on the upper side of the button 5, and both the spring piece and the button 5 are movably installed in the housing on one side of the handle 1; a conductive plate 10 is arranged at intervals below the lower end contact of the conductive rod 8 in the cavity of the handle 1; the conductive plate 10 has a rectangular structure, with a connector on one side that matches the lower end contact of the conductive rod 8, and a neon bulb 7 is fixedly installed on the top surface of the other side, with the top of the neon bulb 7 fixedly installed in a preset mounting port on one side of the handle 1.

[0018] Specifically, the handle 1 serves as the main structure of the entire device, housing internal electrical components such as the conductive rod 8, button 5, spring 9, and conductive plate 10, and providing a gripping area for the operator. The handle 1 is made of insulating material, which can effectively prevent current leakage and ensure operational safety. The arc protection cover 2 is fixedly installed on one side of the handle 1 to form a physical isolation barrier during the measurement process. Its cover covers the outer periphery of the measuring rod 3, which can effectively block arc sputtering and prevent the operator from being burned by the high temperature arc. At the same time, it can guide the current to flow to the top of the measuring rod 3. The measuring rod 3 is fixed on the inner wall of the arc protection cover 2. One end of it is exposed for contact with the power source being tested, and the other end extends into the handle 1 to transmit external electrical signals to the conductive rod 8, thereby realizing current acquisition and detection. The insulating sleeve 4 is fixed to the exposed part of the measuring pole 3, leaving only the top contact end. This can effectively prevent the operator from accidentally touching the conductive part, improve the safety of use, and prevent the electric arc from creeping along the pole and causing short circuits or breakdowns. The conductive rod 8 adopts a "Y" shaped structure and is set in the cavity of the handle 1. Its horizontal arrangement allows its two end contacts to form an electrical connection path with the indicator light 6 and the conductive plate 10 respectively. The middle part can adjust the current transmission node through the button 5 and the spring 9 to distribute different current paths and realize dual detection function. The indicator light 6 is fixedly installed in the mounting groove on the upper part of the handle 1 and is electrically connected to the upper contact of the conductive rod 8. When a weak leakage current is transmitted through the measuring rod 3 and the conductive rod 8, the indicator light 6 can be lit immediately to realize leakage indication under low current conditions. Spring 9 is fixed to the bottom of conductive rod 8 to provide a reset force for conductive rod 8, so that the upper end contact of conductive rod 8 is always in contact with the bottom connection of indicator light 6 to maintain communication when it is not pressed. Button 5 is installed on the top of the handle 1 housing. Pressing it can overcome the elastic force of spring 9 and push the conductive rod 8 downward, so that its lower end contact contacts the conductive plate 10 to conduct electricity, thereby realizing the high voltage detection function. The spring piece on one side of button 5 is used to enhance the rebound and positioning effect of button 5. When button 5 is pressed, the current flows through the resistive element of conductive plate 10 to the neon bulb 7. The neon bulb 7 needs to reach a certain voltage to light up. The operator can judge the voltage level and the severity of leakage based on this, realizing a safe and intuitive current detection process.

[0019] The specific working process of this device; The operator holds handle 1, their hands protected by the insulating material covering handle 1. Simultaneously, an arc protection shield 2 surrounds the outer circumference of the testing rod 3, ensuring the operator is not injured by arcs or high voltage during testing. The protruding top of the testing rod 3 contacts the power source being tested. The current at the exposed end is transmitted through the testing rod 3 to the "Y"-shaped conductive rod 8. At this point, only a weak current flows through the upper contact of the conductive rod 8, connecting with the indicator light 6, which immediately illuminates, indicating to the operator that there is voltage or leakage in the circuit. To determine the voltage level or the severity of the leakage, the operator presses button 5. Button 5 overcomes the rebound force of spring 9 and pushes... The conductive rod 8 moves downward, causing its lower contact point to contact the conductive plate 10. At this time, current is transmitted to the neon bulb 7 through the internal resistance of the conductive plate 10. The neon bulb 7 can only light up when a certain voltage is reached, thus indicating leakage or voltage intensity. The spring piece at the upper position of the button 5 ensures that the conductive rod 8 cannot move downward when not pressed, preventing accidental operation. During the pressing process, the operator must consciously apply force to trigger the high voltage detection, increasing safety. After the button 5 is released, the spring 9 and the spring piece push the conductive rod 8 to automatically reset, disconnecting the high voltage circuit. The neon bulb 7 goes out, but the indicator light 6 can still show the weak current status.

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.
