Description

Technical Field

[0001] This utility model relates to the field of electrical measuring tool technology, and in particular to an electronic megohmmeter extension device. Background Technology

[0002] An electronic insulation resistance meter is an instrument used to test the insulation resistance of electrical equipment. It is mainly composed of medium- and large-scale integrated circuits and features high output power, high short-circuit current, and multiple output voltage levels. Its working principle involves using an internal battery as a power source, generating a high-voltage DC through a DC / DC converter, then performing an I / V conversion and division operation to complete the calculation, finally displaying the measured insulation resistance value on an LCD screen. Electronic insulation resistance meters are commonly used to check the insulation resistance of electrical equipment, household appliances, or electrical wiring to ground and between phases, ensuring that these devices operate under normal conditions and preventing accidents such as electric shock and equipment damage.

[0003] In practical use, due to the design limitations of the megohmmeter itself, its measurement range is often limited. Especially when it is necessary to measure electronic components in a distant or confined space, the operator needs to enter the space, which is not only very inconvenient to operate, but also poses a risk of electric shock. Therefore, how to provide a device that can expand the measurement range of the electronic megohmmeter and improve the measurement efficiency has become an urgent problem to be solved.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] like Figure 1-3 As shown, an electronic megohmmeter extension device includes an insulating rod 1 and a movable block 2, both of which are cylindrical; a detection contact 3 is disposed on the side of the insulating rod 1 away from the movable block 2; and a copper wire 4 is disposed inside the insulating rod 1, with one end of the copper wire 4 passing through the insulating rod 1 and the movable block 2 and extending to the outside of the movable block 2, and a contact point is provided on the outer surface of the copper wire 4.

[0026] Specifically, the end of the copper wire 4 away from the movable block 2 is connected to the detection contact 3, and the movable block 2 has a fixing hole inside that is adapted to the size of the copper wire 4.

[0027] In this embodiment, current leakage can be prevented, ensuring safe use.

[0028] like Figure 1-3 As shown, it also includes an adjustment structure, which includes a slot 5 and a lever 6. The slot 5 is located around the outer surface of the insulating rod 1, and the lever 6 is located around the movable block 2 on the side close to the insulating rod 1. The lever 6 extends into the interior of the slot 5.

[0029] Specifically, there are four slots 5 arranged in a ring at equal intervals. The number of levers 6 is the same as the number of slots 5 and their positions correspond to each other. The size of the levers 6 is adapted to the size of the slots 5, which can effectively prevent the movable block 2 from shifting.

[0030] In this embodiment, the adjustable structure allows for convenient adjustment of the overall length according to usage needs, thereby improving practicality.

[0031] like Figure 1-3 As shown, the adjustment structure also includes a bolt 7, which is located on the outer surface of the clamping rod 6 near the insulating rod 1. The outer surface of the clamping rod 6 has a fixing hole that matches the size of the bolt 7, and the side of the clamping rod 6 near the insulating rod 1 abuts against the clamping groove 5.

[0032] In this embodiment, bolt 7 is used to fix the movable block 2 to prevent expansion and contraction during use.

[0033] like Figure 1-3 As shown, the outer surface of the movable block 2 is provided with anti-slip texture 8, which is spiral in shape. A fixing ring 9 is provided on the side of the outer surface of the movable block 2 away from the insulating rod 1, which is arched in shape.

[0034] In this embodiment, the anti-slip texture 8 facilitates overall grip and minimizes slippage, while the fixing ring 9 facilitates overall carrying.

[0035] The method of using this utility model is as follows:

[0036] Before use, loosen the four bolts 7 so that they do not abut against the slot 5. Move the movable block 2 to the desired length and then reset the bolts 7 so that they abut against the slot 5, so that the detection contact 3 directly rests on the electronic component being tested. The contact on the copper wire 4 is connected to the contact of the megohmmeter through the connecting wire, thereby realizing the transmission of current. When not in use, loosen the four bolts 7 and let the clamping rod 6 fully enter the slot 5, then reset the bolts 7. This reduces the space occupied and makes it convenient for storage and carrying.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
