Embodiment 1

[0034] refer to Figure 1~2 , this embodiment provides a new type of electric energy meter connection terminal, including a connection unit 100, the connection unit 100 is fixedly connected to the electric energy meter, instead of the original connection port, it includes a fixing part 101, a connecting part connected with the fixing part 101 102, and the first conductive member 103 connected with the connecting piece 102, wherein one end of the fixing piece 101 is inserted into the original wiring port of the electric energy meter, the fixing piece 101 is an insulator, the connecting piece 102 is connected with the other end of the fixing piece 101, and the connecting piece 102 is an insulator, and the first conductive part 103 connected by the connector 102 is a conductor; the external connection unit 200, the external connection unit 200 connects the external wire and the electric energy meter through the wiring unit 100, which includes a sleeve 201, located in the sleeve 20...

Embodiment 2

[0037] refer to Figure 1-10 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and the difference from the previous embodiment is that this embodiment provides a new type of electric energy meter terminal, including a terminal unit 100, a terminal unit 100 Fixed on the electric energy meter, instead of the original wiring port, it includes a fixing piece 101, a connecting piece 102 connected with the fixing piece 101, and a first conductive piece 103 connected with the connecting piece 102, wherein one end of the fixing piece 101 is inserted into In the original wiring port of the electric energy meter, the fixing part 101 is an insulator, and the connecting part 102 is connected with the other end of the fixing part 101. The connecting part 102 is also an insulator, and the first conductive part 103 connected to the connecting part 102 is a conductor; the external unit 200 , the external unit 200 connects the external wire...

Embodiment 3

[0047] refer to Figure 1-11 , is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that it also includes an electric energy meter 300. The difference between the electric energy meter 300 and the existing electric energy meter is that the electric energy meter 300 is set There is a terminal hole 301 and a second wire L2. The fixing part 101 also includes a connection end 101c and a limiting boss 101d. The limiting boss 101d prevents the clamping post 203 from moving offside to the fixing part 101 when the external unit 200 is operated. The end 101c is connected to the terminal hole 301, and the connection method is but not limited to screw connection. The second wire L2 protrudes from the terminal hole 301 of the electric energy meter 300 and passes through the fixing part 101, the connecting part 102 and the first conductive part in sequence. 103, so that when the terminal of...

Abstract

The invention discloses a novel electric energy meter wiring terminal which comprises: a wiring unit which comprises a fixing piece, a connecting piece connected with the fixing piece and a first conductive piece connected with the connecting piece; and an external connection unit which comprises a sleeve and a second conductive part located in the sleeve; the first conductive part is in contact with the second conductive part; a wiring unit arranged in the device is fixedly connected to an original interface of the electric energy meter; when the electric energy meter is wired, the arranged external connection unit is directly inserted into the wiring unit after being connected with a wire; and the wiring area of the wiring terminal is increased, the problem that the contact surface is too small to bear the passing current to burn out the ammeter is avoided, the operation and maintenance cost of the ammeter and the labor intensity and operation risk of operators are reduced, and a solid foundation is laid for the safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a novel electric energy meter connection terminal. Background technique [0002] With the rapid development of our country's economy, the demand for electricity in all walks of life is increasing. Where there is electricity, there must be an electric energy meter. The electric energy meter plays an important role in the power system. Every year, when the electric energy meter is installed, the connecting head of the wire and the terminal of the electric meter are not tightened or the copper-aluminum transition treatment is performed, resulting in poor contact or oxidation, or the wire used is a single-core wire, so the contact surface is too small to bear the current burnt through. The terminal post of the electric energy meter is damaged, which leads to the normal failure of the electric energy meter, and the user complaints caused by the burning of the electric meter and t...
