[0076] In other words, this solution highly integrates the functional parts of the magnetic latching relay and the functional parts of multiple groups of terminal block assemblies to form a smart meter control module with a control switch function, which facilitates the assembly and automated production of smart meters.

[0077] In this scheme, if Figure 1 As shown, the housing comprises: a base 1 and a first upper cover 2;

Accordingly, the first upper cover 2 is provided with two positioning column circular holes 24, which are used to match the first positioning column 16 and the second positioning column 17 at the top of the base 1 one by one; of course, as Figure 1 As shown, after the first upper cover 2 is positioned and assembled on the top of the base 1, the first positioning column 16 and the second positioning column 17 will pass through the positioning column circular hole 24 of the first upper cover 2, thereby facilitating the installation and fixation with the PCB board; and the rear part of the top wall of the first upper cover 2 is provided with two terminal outlets, and the two switch control terminals 5 (i.e., the positive switch control terminal and the negative switch control terminal) pass through the top wall of the first upper cover 2 respectively through the terminal outlets;

[0090] like Figure 6 As shown, each switch control terminal can be an L-shaped switch control terminal, and is respectively arranged on the skeleton 65 of the magnetic circuit assembly, and is respectively electrically connected to the enameled wire wound on the skeleton 65, and the vertical parts of the positive switch control terminal and the negative switch control terminal both pass through the top wall of the first upper cover 2.

[0091] That is to say, the shell of the present solution adopts the form of a base 1 + an upper cover, which can facilitate the installation of the functional parts of the magnetic holding relay and the functional parts of the terminal base assembly, and the base 1 is provided with a card slot or groove for installing the functional parts of the magnetic holding relay and the functional parts of the terminal base assembly, which not only facilitates the installation of the functional parts of the magnetic holding relay and the functional parts of the terminal base assembly in the base, but also makes the functional parts of the magnetic holding relay and the functional parts of the terminal base assembly occupy and fix their positions in the base 1, and the moving piece 61, the static piece 62 and the neutral wire assembly are all provided with an extended end, which is convenient for being pressed together with the external cable extending into the pulling terminal 72 by the screw 71, which makes it more convenient to electrically connect the functional parts of the magnetic holding relay and the external cable on the functional parts of the terminal base assembly, and makes it more convenient to electrically connect the neutral wire assembly and the external cable on the functional parts of the terminal base assembly. Of course, this will also make the assembly of this module convenient and quick, thereby making it easier to assemble and automate the production of smart meters.

[0105] like Fig. 9 As shown, the two current sampling terminals 8 and the top of the moving piece 61 of the contact assembly are an integrated structure and pass through the top wall of the shell. That is to say, the two current sampling terminals 8 added to the smart meter control module are exposed on the top wall of the shell (the top wall of the first upper cover 2). When the PCB board is installed on the top wall of the shell, the two current sampling terminals 8 can be easily passed through the PCB board respectively, and each current sampling terminal 8 can be soldered to the PCB board by solder. In this way, the function of current collection can be realized for the smart meter, and the current sampling terminal 8 and the top of the moving piece 61 form a whole, which saves module space and module cost. In addition, when the contact assembly of the functional part of the magnetic latching relay is three groups, that is, when it is used in a three-phase power scenario, the top of the moving piece 61 of each group of contact assemblies can be provided with the above-mentioned two current sampling terminals 8, and the above-mentioned two current sampling terminals 8 can also be provided on the top of the neutral line assembly, and the above-mentioned current sampling terminals 8 all pass through the top wall of the shell. Of course, the top wall of the shell (the top wall of the first upper cover 2) is also provided with corresponding terminal outlets 25.

[0106] Furthermore, if Figure 1 As shown, the highly integrated smart meter control module provided by the embodiment of the utility model at least includes: a first voltage detection terminal 91 and a second voltage detection terminal 92;

[0108] The second voltage detection terminal 92 is arranged outside the top wall of the shell, and part of it penetrates into the top wall of the shell and is electrically connected to the static piece 62 of the contact assembly. That is to say, the first voltage detection terminal 91 and the second voltage detection terminal 92 added to the smart meter control module are both exposed on the top wall of the shell (the top wall of the first upper cover 2). When the PCB board is installed on the top wall of the shell, the first voltage detection terminal 91 and the second voltage detection terminal 92 can be conveniently passed through the PCB board respectively, and the voltage detection terminal and the PCB board can be welded by solder, so that the voltage detection function of the smart meter can be realized, and the first voltage detection terminal 91 and the top of the moving piece 61 form a whole, which saves the module space and saves the module cost. In addition, when the contact components of the functional parts of the magnetic holding relay are three groups, that is, when it is used in a three-phase power scenario, the top of the moving piece 61 of each group of contact components can be provided with the above-mentioned first voltage detection terminal 91, and the static piece 62 can be electrically connected to part of the second voltage detection terminal 92; of course, the top wall of the shell (the top wall of the first upper cover 2) is also respectively provided with corresponding terminal outlets 25.

[0109] In this scheme, if Fig.11 As shown, the second voltage detection terminal 92 is a sheet structure and is provided with an upper contact arm 921 and a lower contact arm 922. The upper contact arm 921 is located outside the top wall of the shell and is used to contact and cooperate with the PCB board. The lower contact arm 922 penetrates into the top wall of the shell and is electrically connected to the static sheet 62 of the contact assembly.

[0110] Among them, Figure 5 As shown, the top wall of the first upper cover 2 is provided with a voltage detection terminal mounting groove 26. After the second voltage detection terminal 92 is installed in the voltage detection terminal mounting groove 26, it can be riveted by rivets, so that the second voltage detection terminal 92 can be embedded in the top wall of the first upper cover 2 to avoid interference with the assembly of the PCB board. The top wall of the first upper cover 2 is also provided with an upper contact arm mounting groove, and is connected with the voltage detection terminal mounting groove 26. In this way, when the PCB board is assembled to the top wall of the first upper cover 2, the upper contact arm 921 can be pressed into the upper contact arm mounting groove, which also avoids interference with the assembly of the PCB board. The number of the lower contact arms 922 can be two, and both are inserted into the top wall of the first upper cover 2 and are electrically connected to the static sheet 62 respectively, which facilitates the formation of multi-point contact, reduces the contact impedance, and makes the contact between the lower contact arm 922 and the static sheet 62 more reliable.

[0111] In other words, this solution highly integrates the functional parts of the magnetic latching relay with the functional parts of the terminal block assembly and other components to form a smart meter control module that integrates control switches, current sampling, voltage detection and other functions. Moreover, the smart meter control module has a compact and simple structure, which is convenient for the assembly and automated production of smart meters, and of course, it is also convenient for external power grid connection.
