Problems solved by technology

[0003] In the prior art, the electric energy meter terminals are usually made of nickel-plated copper (Gu59-1), the fastening screws are made of iron, and the external wires are made of copper or iron. Due to the long-term transmission of large currents, electric corrosion occurs, making the contacts The contact resistance increases, and the contact overheats, causing the electric energy meter to burn out
Due to the large number of burnt electric energy meters, it poses a threat to electricity safety and national economic losses

Embodiment Construction

[0011] see figure 1 , 2 , 3. The names of the parts are as follows: cylindrical body 1, opening 2, spiral pattern 3, wire 4, locking screw 5, and electric energy meter terminal 6.

[0012] see figure 1 , 2 3. The anti-corrosion pressure plate for electric energy meter wiring includes a cylindrical body 1, openings 2 in the middle and one side, and spiral patterns 3 on the upper and lower sides of the opening 2. The whole is tin-plated. For example, the cylindrical body 1 has an outer diameter of 9.6mm, a length of 17mm, and an opening height of 4mm, which is suitable for a wire with an outer diameter of 3mm and 4mm. The whole is tin-plated, and tin or zinc is used for material transition to solve the problem of electric corrosion. The pressure plate is cylindrical, with an opening in the middle, with spiral threads inside (to ensure tight crimping), and the outer tin or zinc plating of copper is used to solve the problem of copper-aluminum transition and copper-iron tra...

Abstract

The invention relates to a power supply apparatus, namely, an electric energy meter wiring electric corrosion prevention pressing plate. The electric energy meter wiring electric corrosion prevention pressing plate comprises a cylindrical body, and is characterized in that the middle and one side of the cylindrical body are provided with an opening, the upper and lower surfaces inside the opening are provided with spiral threads, and the whole body is completely tinned. The opened pressing plate can be deformed, thereby increasing the connection area of a wire, reducing the contact resistance, being firm in connection point and reducing heat generation of the connection point. The electric energy meter wiring electric corrosion prevention pressing plate uses tin or zinc to perform material transition, solves a problem of electric corrosion, solves a problem of copper-aluminum transition and copper-iron transition electric corrosion and reduces heat generation of the connection point. The electric energy meter wiring electric corrosion prevention pressing plate is reasonable in structure, compact, flexible and easy to use.

Description

[0001] technical field [0002] The invention relates to a power supply appliance, that is, an anti-corrosion pressure plate for wiring of an electric energy meter. Background technique [0003] In the prior art, the electric energy meter terminals are usually made of nickel-plated copper (Gu59-1), the fastening screws are made of iron, and the external wires are made of copper or iron. Due to the long-term transmission of large currents, electric corrosion occurs, making the contacts The contact resistance increases, and the contact overheats, causing the electric energy meter to burn out. Due to the large number of burnt electric energy meters, it brings threats to electricity safety and national economic losses. Contents of the invention [0004] The object of the present invention is to provide an anti-corrosion pressure plate for electric energy meter wiring to solve the above-mentioned shortcomings. Provided is a pressing plate for wiring, which solves the electri...
