[0042] Such as Figures 1-10As shown in the figure, the present utility model provides a multifunctional three-phase intelligent electric energy meter, which includes a housing 100, a control board and a display screen 200. In the present utility model, the control board is arranged inside the housing 100, the display screen 200 is arranged on the housing 100, and the control board is connected to the display screen 200. The display screen 200 obtains the content of the control board for display. It should be noted that the control board in the present utility model is preferably the circuit board built in the three-phase intelligent electric energy meter in the prior art. Therefore, the present utility model will not further explain this. In addition, a prepaid module, an automatic alarm module, etc. can be set on the control board according to actual needs, specifically subject to the actual situation. At the same time, the prepaid module, the automatic alarm module, etc. on the control board all adopt the prior art, and the present utility model will not further explain this. It also includes:

[0043] An installation block 300 is arranged on the housing 100; and a plurality of through holes 301 and a plurality of pressing holes 302 are formed in the installation block 300, and the plurality of pressing holes 302 communicate with the plurality of through holes 301. Specifically, threaded holes can be arranged on the housing 100, and after passing through the housing 100 through the threaded holes, they are connected to the installation block 300, so as to fix the installation block 300 on the housing 100. A plurality of wiring cores 400 are arranged in the plurality of through holes 301, and a connection coil 500 is arranged in the wiring core 400. In the present utility model, the plurality of wiring cores 400 are connected to the control board and are connected to external wires through the wiring cores 400, so as to realize the connection between the external wires and the control board. The external wires enter through the plurality of through holes 301 and are inserted into the wiring cores 400. By contacting the wire cores of the external wires with the wiring cores 400, the connection between the control board and the external wires is realized. Among them, one end of the through hole 301 close to the pressing hole 302 gradually shrinks to the end far from the pressing hole 302. When the external wires enter the through hole 301, the wires can be guided through the through hole, so that the wires can better reach the position where the wiring cores 400 are located.

[0044] A plurality of pressing groups 600 are arranged in the plurality of pressing holes 302; a fixing block 700 is arranged on the housing 100. When in the installed state, the fixing block 700 squeezes the plurality of pressing groups 600, so that the plurality of pressing groups 600 are pressed into the plurality of through holes 301. After the plurality of wiring cores 400 are respectively connected to the external wires, the fixing block 700 is connected to the housing 100. Under the action of the fixing block 700, the pressing groups 600 move linearly in the pressing holes 302, and during the movement, one end of the pressing group 600 will enter the through hole 301 and contact the external wires in the through hole 301, and the external wires placed in the through hole 301 are pressed tightly through the cooperation of the through hole 301 and the pressing group 600, so as to complete the fixing of the external wires in the through hole 301.

[0045] It should be noted that the mounting block 300 includes a first block body and a second block body; the first block body and the second block body can be connected by screws or by bonding; specifically, it depends on the actual situation. During the installation stage, after separating the first block body and the second block body, several pressing groups 600 are placed in the pressing holes 302, and then the connection between the first block body and the second block body is carried out; and after the first block body and the second block body are connected, several pressing groups 600 are respectively restricted in several pressing holes 302; in addition, in the present utility model, the number of the through holes 301, the pressing holes 302, the connection cores 400 and the pressing groups 600 is the same, preferably 7; therefore, when connecting to external wires, 7 external wires need to be respectively passed through the through holes 301 and then connected to the connection cores 400; when connecting the fixing block 700, the fixing block 700 can simultaneously squeeze 7 pressing groups 600, and after squeezing, the 7 pressing groups 600 respectively press tightly 7 external wires placed in 7 through holes 301.

[0046] The technical solution of the present utility model is to set the mounting block 300 on the housing 100, and place several connection cores 400 in several through holes 301 respectively. When connecting to external wires, the external wires are directly inserted from the through holes 301 into the connection cores 400 and connected to the wires through the connection coils 500; when the wires are placed in the connection coils 500, the fixing block 700 is installed on the housing 100, and several pressing groups 600 are squeezed during the installation process, so that several pressing groups 600 enter several through holes 301, and the external wires placed in the through holes 301 are restricted by several pressing groups 600, thereby ensuring that the external wires are fixed in the through holes 301; compared with the prior art, the technical solution of the present utility model can directly connect the wires to the connection coils 500 after inserting the wires into the through holes 301, and under the action of the fixing block 700, the positions of the external wires in the through holes 301 are restricted by several pressing groups 600, thereby realizing the connection between the external wires and the connection cores 400, without the need to use tools for operation, improving the installation efficiency and ensuring the stability of the external wires after installation.

[0047] Such as Figure 10As shown in the figure, the wiring core 400 includes: a connecting column 401, a wiring head 402, and a connection coil 500. One end of the connecting column 401 is connected to the control board, and the other end passes through the through hole 301; the wiring head 402 passes through the other end of the connecting column 401; the connection coil 500 passes through the wiring head 402; when installing an external wire, one end of the external wire is inserted into the through hole 301, and during the gradual insertion process, it enters the wiring head 402, and after being guided by the wiring head 402, it enters the position where the connection coil 500 is located and presses against the docking coil 500. Since the connection coil 500 itself has elasticity, after being pressed by the wire core, the connection coil 500 will press the wire core of the external wire under the action of elastic deformation, thereby completing the connection between the connection coil 500 and the external wire; it should be noted that in the present utility model, the diameter of the end of the wiring head 402 away from the wiring column is larger than the diameter of the end close to the wiring column, so that one end of the wiring head 402 forms a large opening structure; and the inner part of this end is set as an inclined surface; in this way, when the external wire is inserted into the position of the wiring head 402, the large opening structure can enable the external wire to enter the wiring head 402 better, and through the guidance of the inclined surface, it can enter the connection coil 500 more easily; the installation efficiency is improved;

[0048] In the present utility model, the connection coil 500 includes a connection wall 501 and a plurality of elastic pieces 502 arranged on the inner surface of the connection wall 501; the connection wall 501 contacts the installation hole inside the wiring head 402; thereby restricting the positions of the plurality of elastic pieces 502. In the present utility model, the plurality of elastic pieces 502 are of a hollow structure. When the external wire contacts the plurality of elastic pieces 502, the plurality of elastic pieces 502 will be deformed by the external wire being pressed; and when the external wire separates from the plurality of elastic pieces 502, the plurality of elastic pieces 502 will reset under the action of their own elastic deformation; among them, the connecting column 401, the wiring head 402, and the connection coil 500 are all made of conductive materials (such as copper) so that electrical energy can be transmitted after being connected to the external wire; the installation block 300 and the pressure group 600 are both made of insulating materials (such as insulating plastic) to ensure that there is no electric leakage during use.

[0049] Of course, for better adaptation to the installation of external wires; in the present utility model, a ball groove 403 is provided on the connection column 401; a ball head 404 is provided on the wiring head 402; the ball head 404 is arranged in the ball groove 403; in this way, the wiring head 402 can rotate within the ball groove 403; of course, due to the structural limitation of the through hole 301, the movement range of the wiring head 402 is limited; in addition, according to different usage requirements, the sizes of the through hole 301 and the wiring head 402 can be changed to suit different needs, and the present utility model will not further elaborate on this; when the external wire contacts the wiring head 402, it can drive the wiring head 402 to rotate on the connection column 401, and during the rotation, the external wire is guided by the wiring head 402 into the coil 500, completing the connection between the wire and the coil 500; during this process, the wiring head 402 can adapt to the angle of the external wire, avoiding the situation in the prior art where the external wire and the terminal hole are not aligned and cannot be installed.

[0050] As Figure 10 shown, the pressing group 600 includes a pressing block 601 and a reset member 602, the pressing block 601 is inserted into the pressing hole 302; the reset member 602 is arranged in the pressing hole 302; and the reset member 602 is sleeved on the pressing block 601; specifically, an elastic space 303 is provided in the pressing hole 302, and the reset member 602 is restricted within the elastic space 303; and the position of the reset member 602 is restricted by the elastic space 303; as Figure 7 shown, the pressing block 601 includes a pressing column 611 and a pressing head 612 arranged at one end of the pressing column 611; the pressing column 611 is inserted into the pressing hole 302, and the reset member 602 is sleeved on the pressing column 611; wherein, a pressing plate 614 is further provided on the pressing column 611; after installation, the pressing column 611 is restricted within the elastic space 303 by the pressing plate 614, and the reset member 602 is limited by the pressing plate 614; when the fixing block 700 is installed, the pressing column 611 is pressed into the pressing hole 302, and during the movement of the pressing column 611, the pressing plate 614 moves simultaneously with the pressing column 611 and squeezes the reset member 602; when disassembly is required; separate the fixing block 700 from the housing 100, and under the action of the reset member 602, the pressing plate 614 is pushed to move within the pressing hole 302, thereby resetting the pressing column 611.

[0051] As Figures 8-10As shown in the figure, one end of the pressing post 611 is provided with an inclined surface. During the installation process of the fixing block 700, it contacts the inclined surface, and after passing through the inclined surface, the pressing post 611 is pressed into the pressing hole 302. At the same time, the other end of the pressing post 611 is provided with a pressing opening 613. After the pressing post 611 is pressed into the pressing hole 302 by the fixing block 700, the other end of the pressing post 611 will enter the through hole 301, and the external wire placed in the through hole 301 is tightly pressed through the pressing opening 613. By means of the pressing opening 613, it can contact both sides of the external wire, increasing the contact area and thus improving the pressing effect.

[0052] As Figures 2-5 As shown in the figure, sliding grooves 101 are provided on both sides of the housing 100, and sliding blocks 701 are provided on both sides of the fixing block 700. The sliding grooves 101 are adapted to the sliding blocks 701. When installing the fixing block 700, the sliding block 701 is placed in the sliding groove 101, and the fixing block 700 is pushed to move. Due to the cooperation of the sliding block 701 and the sliding groove 101, when the fixing block 700 is pushed, the fixing block 700 will slide into the housing 100 and squeeze the pressing group 600 during the sliding process. In addition, fixing holes are provided on the fixing block 700. After the fixing block 700 reaches the preset position, a bolt is inserted into the fixing hole to fix the fixing block 700 with the screw hole (not shown in the figure) on the mounting block 300. It should be noted that the fixing block 700 is fixed to the mounting block 300 by an internal hexagonal screw, which can reduce the operating space required for tools during installation. In addition, a cover 800 is provided on the housing 100. The cover 800 can be hinged to the housing 100. After the fixing block 700 is installed, the cover 800 can be buckled on the fixing block 700 to protect the fixing block 700 from direct external contact.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
