[0023] Embodiment

[0024] This embodiment provides a connection device for an electric energy meter relay. The electric energy meter includes a relay 1 and a conductive rod 2 connected to the relay 1. A copper sheet 3 extends from the side of the relay 1. The connection device is arranged between the copper sheet 3 and the conductive rod 2. The connection device includes a positioning post 4 arranged on one side of the copper sheet 3 or the conductive rod 2 and a positioning hole 5 into which the positioning post 4 can be inserted. The positioning post 4 is fixedly arranged in the positioning hole 5.

[0025] Based on the above embodiment: The positioning post 4 includes a connecting end 41 and a riveting end 42. The connecting end 41 can pass through the positioning hole 5, and the riveting end 42 is fixed on the upper end surface of the positioning hole 5.

[0026] Based on the above embodiment: The positioning post 4 is arranged on the conductive rod 2, and the positioning hole 5 is arranged on the copper sheet 3.

[0027] Based on the above embodiments: The copper sheet 3 includes a first bent sheet 31 connected to the relay 1 and a second bent sheet 32 connected to the conductive rod 2. The positioning hole 5 is opened at the second bent sheet 32. An extension piece 6 capable of fitting with the conductive rod 2 is arranged on the side of the second bent sheet 32. The extension piece 6 and the second bent sheet 32 are arranged in an "L" - shaped structure.

[0028] The above - mentioned specific improvement is as follows: As Figure 1 shown, one end of the copper sheet 3 is inserted into the relay 1, and the other end is connected to the conductive rod 2. A positioning post 4 and a positioning hole 5 adapted to the positioning post 4 are arranged at the connection part of the copper sheet 3 and the conductive rod 2. When connecting, the positioning post 4 is inserted into the positioning hole 5.

[0029] Embodiment 1: The positioning post 4 is arranged on the conductive rod 2, and the positioning hole 5 is arranged on the second bent sheet 32. After the positioning post 4 is inserted into the positioning hole 5, it can ensure the preliminary positioning between the copper sheet 3 and the conductive rod 2. Then, an external riveting machine is used to punch the positioning post 4, so that the positioning post 4 is riveted in the positioning hole 5.

[0030] Embodiment 2: The positioning post 4 is arranged on the lower end face of the second bent sheet 32, and the positioning hole 5 is arranged on the upper end face of the conductive rod 2. When connecting, the positioning post 4 is inserted into the positioning hole 5, and soldering is used for welding. The positioning post 4 and the positioning hole 5 can be mutually adapted, so that rapid positioning can be achieved during welding, improving the operation efficiency.

[0031] Compared with the prior art, the insertion of the positioning post 4 and the positioning hole 5 between the second bent sheet 32 and the conductive rod 2 can quickly perform preliminary positioning, and then secondary positioning is carried out in the form of welding or riveting. This simplifies the connection process between the two, improves the operation efficiency, and can avoid the loosening of the positioning post 4 and the positioning hole 5 after connection.

[0032] Based on the above embodiments: A card slot 7 for the second bent sheet 32 to be inserted into is arranged on the conductive rod 2.

[0033] The above - mentioned specific improvement is as follows: As Figures 1 - 4 shown, to increase the contact area between the conductive rod 2 and the power supply, increasing the contact area can reduce the current flow (the current flow capacity is the same as the maximum peak current). This can prevent the rapid temperature rise between the conductive rod 2 and the copper sheet 3 due to excessive current, thus avoiding de - soldering between the two or the melting of the housing due to too high a temperature at the connection. Through the setting of the second bent sheet 32, the contact area between the conductive rod 2 and the copper sheet 3 can be increased, thereby reducing the current flow and lowering the temperature at the connection of the conductive rod 2 and the copper sheet 3. And through the setting of the card slot 7, the second bent sheet 32 can be inserted into the card slot 7, making the connection between the two more tight.

[0034] On the basis of the above embodiments: An auxiliary positioning device 8 is provided between the extension piece 6 and the conductive rod 2. The auxiliary positioning device 8 includes a connecting column 81 provided on one side of the conductive rod 2 or the extension piece 6 and an auxiliary hole 82 provided on the other side and adapted to the connecting column 81.

[0035] The above specific improvement is as follows: As Figure 3 and Figure 4 shown, in order to further improve the connection strength between the second bending piece 32 and the conductive rod 2, a connecting column 81 is provided on the side of the conductive rod 2. When connecting, first align the extension piece 6 and the conductive rod 2, snap the connecting column 81 into the auxiliary hole 82, then align the second bending piece 32 with the upper end face of the conductive rod 2 so that the positioning column 4 snaps into the positioning hole 5, and finally use an external riveting machine to rivet the positioning column 4 and the connecting column 81.

[0036] Obviously, the above embodiments are only examples given clearly and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
