Technical Field

[0001] The invention relates to the field of meter installation and power connection tools, and in particular to a convenient and practical insulated current and voltage meter installation and power connection tool. Background Art

[0002] There are many problems with traditional tools and methods in the work of installing meters and connecting electricity. In terms of current short-circuiting, simple short-circuit pieces or wire connections were often used in the past, which were complicated to operate and inefficient; for voltage line insulation, a common practice is to use homemade insulating sleeves or silicone tube covers, but these methods have poor reliability. Homemade insulating sleeves often lack standardized designs, and are prone to problems such as size mismatch and loose fixation. In actual use, they may slip off or fail to completely cover the metal head, exposing the copper wire, posing serious safety hazards. Although the silicone tube cover has a certain insulation effect, it is easy to age and break after long-term use or in complex environments, reducing the insulation performance; in terms of tool operation convenience, traditional tools lack an overall design, and the various components are scattered. During operation, tools need to be frequently replaced and operating postures adjusted, which increases the labor intensity of operators.

[0003] Therefore, it is necessary to propose a convenient and practical tool for insulating current and voltage meter connection to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a convenient and practical insulated current and voltage meter connection tool to solve the problem that the metal head may slip off or fail to completely cover the copper wire during actual use, and the traditional tools lack an overall design and have scattered components.

The screwing-in setting makes the copper wire not easy to bend and will not damage the insulating wire tube 12. When it is necessary to short-circuit part of the circuit, it can be done by the following two methods. The first method is to manually hold the rotating arm 2 and directly insert the quadruple current sealing plug 6 into the corresponding terminal row hole to ensure good contact to achieve short-circuit. The second method is to use a short-circuit wire to connect with the quadruple current sealing plug 6. First, insert one end of the short-circuit wire into the quadruple current sealing plug 6.

[0030] Working principle of the present invention: This portable current and voltage tool plays an important role in the work of installing meters and connecting electricity. For the treatment of exposed live copper wires, select a suitable wire slot according to the size of the copper wire, place one end of the copper wire in the wire slot 14, and put the other end into the insulating wire tube 12, close the crocodile wire clamp 7 to clamp and fix the copper wire clamp block 13, rotate the knob 10 to make the threaded shaft 9 drive the insulating wire tube 12 to be installed on the copper wire, so as to achieve fixed wrapping of the copper wire. When performing a circuit short-circuit operation, there are two ways: one is to manually hold the rotating arm 12 to insert the four-link current seal 6 directly into the terminal row hole; the other is to connect the four-link current seal 6 through the short-circuit wire, first insert one end of the short-circuit wire into the wire hole 17 and fix it, and then insert the other end into the terminal row hole. During direct insertion, push the push rod 1501, so that the movable lock rod 1507 pushes the movable lock block 1508 to slide into the inclined slot 1511, and the lock core 1510 moves down to release the lock. Under the action of the spring, the push rod 1501 drives the clamping plate 16 away from the four-link current seal 6, so that it can be separated from the installation box 5 for operation or replacement. After the work is completed, rotate the rotating arm 1 2 and the rotating arm 2 3, pass the bar buckle 22 through the closed bayonet 21 and rotate to lock it to avoid damage to the tool.
