And the copper part installation unit 122 includes a first (elastic) hook 1221, a second hook 1222, a third hook 1223, a fourth hook 1224, a fifth hook 1225, a sixth hook 1226, a first connection hole 1227 and a second connection hole 1228. The first connection hole 1227 is located between the first hook 1221, the second hook 1222 and the third hook 1223. And the second connection hole 1228 is located between the fourth hook 1224, the fifth hook 1225 and the sixth hook 1226. The clamping ends of the first hook 1221, the second hook 1222, the third hook 1223, the fourth hook 1224, the fifth hook 1225 and the sixth hook 1226 all face the direction in which the bottom cover 120 is away from the main housing 110;

[0025] The circuit board module 200 includes a circuit board 210, a display connection interface 220 (RJ12 interface) and connection terminals 230. The display connection interface 220 and the connection terminals 230 are respectively electrically connected to the circuit board 210. The display connection interface 220 is installed in the interface installation area 111. And the connection terminals 230 are installed in the connection terminal installation area 121;

[0026] The plug-in copper part module 300 includes a first plug-in copper part 310 and a second plug-in copper part 320. Both the first plug-in copper part 310 and the second plug-in copper part 320 are provided with integrally formed plug-in ends 311, fixed ends 312 and connection ends 313. The fixed end 312 is located between the plug-in end 311 and the connection end 313. One end of the plug-in end 311 of the first plug-in copper part 310 away from (corresponding to) the fixed end 312 penetrates through the first connection hole 1227. One end of the plug-in end 311 of the second plug-in copper part 320 away from (corresponding to) the fixed end 312 penetrates through the second connection hole 1228. The fixed end 312 of the first plug-in copper part 310 is respectively clamped with the first hook 1221, the second hook 1222 and the third hook 1223. The fixed end 312 of the second plug-in copper part 320 is respectively clamped with the fourth hook 1224, the fifth hook 1225 and the sixth hook 1226. The connection end 313 is provided with a connection plug 314. And the connection plug 314 is electrically connected to the circuit board 210 (the plug-in copper parts are stably installed on the bottom cover through each hook).

[0027] Specifically, an isolation block 330 is provided between the first plug-in copper part 310 and the second plug-in copper part 320.

[0028] More specifically, the first plug-in copper part 310 and the second plug-in copper part 320 are axisymmetric.

[0029] Furthermore, both the first plug-in copper part 310 and the second plug-in copper part 320 are provided with plating layers.

[0030] Even further, the display connection interface 220 is used to connect to a display screen.

[0031] Regarding this utility model:

[0032] Compared with conventional rail-mounted electric meters, the volume of this electric meter is 45*72*75, which only occupies about half of the original volume. And this electric meter has all functions except the liquid crystal display button and can directly transmit data through RS485. At the same time, during the design stage, considering that some customers may need to use a liquid crystal display, an RJ12 display connection interface is reserved on the electric meter, which can be connected to a display screen later and can be used in a split form. Whether to use it specifically can be selected according to different customer needs. And the reason why this electric meter is called a socket-type electric meter is that the sampling copper parts are specially treated during the design. The direct plug-in copper parts are used and plating layers are added to the copper parts, so that this electric meter can be directly inserted into the corresponding current output clip in a plug-in form, which is convenient for installation. After adding the plating layer to the copper parts, this electric meter can meet the environment where customers need to use it as a component. The shell of the electric meter uses high-temperature resistant materials. After this measure, the electric meter can be used as a plug-in and directly inserted into the customer's component, and the electric meter can be connected to the customer's equipment by passing through. To sum up, this micro socket-type three-phase multifunctional electric meter is mainly aimed at meeting the demand for a perfect three-phase electric meter function with as small a volume as possible.

[0033] The beneficial effects of this utility model are as follows:

[0034] 1. The micro socket-type three-phase multifunctional electric meter is smaller than the conventional three-phase electric meter and does not occupy space.

[0035] 2. Using socket-type copper parts reduces the problem of locking screws for the copper part connection wires and avoids a series of contact problems caused by locking screws. At the same time, supporting the reflow soldering as a component and the socket-type installation method gives customers more choices and is more convenient for installation.

[0036] 3. An RJ port is reserved and can be connected to an external display screen. Customers can freely choose according to their own needs.

[0037] It is worth mentioning that the technical features such as the display screen involved in the patent application of the present utility model should be regarded as the prior art. For the specific structures, working principles, control methods, and spatial arrangement methods that may be involved in these technical features, conventional selections in the art can be adopted, and they should not be regarded as the inventive points of the patent of the present utility model. The patent of the present utility model will not be further specifically elaborated.

[0038] For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
