TECHNICAL FIELD

[0001] The application relates to the technical field of electric energy meters, and in particular to a machine body and a multi-user electric energy meter. BACKGROUND

[0002] A multi-user electric energy meter is a device used for measuring and recording the electricity consumption of multiple independent users simultaneously. It is widely used in scenarios such as apartment buildings, commercial buildings, and industrial facilities, and can accurately measure and manage the electricity consumption of each user. With the development and popularization of smart grids, multi-user electric energy meters have been widely used in power systems.

[0003] A multi-user electric energy meter usually includes multiple slave machines (i.e., electric energy meters) and a master machine (i.e., a controller). The multiple slave machines are connected to the master machine for data transmission, and the master machine can manage the multiple slave machines.

[0004] Currently, in the structure of a multi-user electric energy meter, the master machine and the slave machines are arranged side by side, and the adjacent master machine and slave machine, and the adjacent slave machines are connected by wires to realize data transmission and communication between the slave machines and the master machine. The disadvantage of this structure is that the timeliness of data transmission and the stability of communication are not good. CONTENT OF THE UTILITY MODEL

[0005] The application provides a machine body and a multi-user electric energy meter, which changes the electrical connection structure between the master machine and the slave machines to improve the data transmission and communication quality between the master machine and the slave machines.

[0006] The technical solution of the application is as follows:

[0007] In a first aspect, the application provides a machine body for a multi-user electric energy meter, the machine body comprising an electrical connection structure.

[0008] The machine body is a master machine, and the electrical connection structure comprises one of a pin and a socket, and the electrical connection structure is arranged on one side of the master machine for connecting with a slave machine.

[0009] Alternatively, the machine body is a slave machine, and the electrical connection structure comprises a pin and a socket, and the pin and the socket are arranged on opposite sides of the machine body.

[0010] In a second aspect, based on the same inventive concept, the application provides a multi-user electric energy meter, which comprises at least two machine bodies, and the machine body is the machine body described above. The adjacent two machine bodies are electrically connected through the pin and the socket inserted into each other.

[0011] The body provided in the first aspect comprises an electric connection structure, which is at least one of the plug pin and the socket. Based on the structure body, the adjacent bodies can be electrically connected through the plug pin and the socket. Thus, compared with the prior art, the multi-user electric energy meter provided in the application eliminates the connecting wires between the adjacent bodies, and the bodies are directly connected through the hard connection of the plug pin and the socket to realize the electrical connection, so that the connection between the bodies is more convenient and reliable, and the data transmission and communication quality between the bodies are improved.

[0012] In addition, the plug pin and the socket are arranged on the opposite sides of the slave machine, so that the cascade connection between the master machine and multiple slave machines can be realized. In addition, the plug pin and the socket are arranged on the opposite sides of the slave machine, and the multiple single-phase slave machines used when the multi-user electric energy meter is assembled can adopt the same structure, and the multiple three-phase slave machines used when the multi-user electric energy meter is assembled can also adopt the same structure, so that the design and production of the slave machine are facilitated, and the assembly of the multi-user electric energy meter is also facilitated.

[0013] In a possible actual case, the body is a slave machine, and the body comprises a machine shell, one of the plug pin and the socket is located in the machine shell, and the other of the plug pin and the socket is outwardly protruding relative to the machine shell.

[0014] Based on the same inventive concept, the application further provides a multi-user electric energy meter using the above-mentioned body. One of the two adjacent bodies is a first body, and the other of the two adjacent bodies is a second body. The first body comprises a first machine shell, and the electric connection structure for connecting the second body is located in the first machine shell. The second body comprises a second machine shell, and the electric connection structure for connecting the first body is outwardly protruding relative to the second machine shell. The electric connection structure for connecting the first body is inserted into the machine shell of the first body.

[0015] Based on the body and the multi-user electric energy meter provided in the embodiment, when the two adjacent bodies are connected, the plug pin of the second body is inserted into the socket of the first body, and at the same time, the plug pin of the second body is also inserted into the machine shell of the first body. In this way, the connection between the first body and the second body is more compact, and the installation space is more saved. In addition, in some cases, the gap between the two adjacent bodies is very small, the seamless connection can be achieved, and the foreign matter falling between the two adjacent bodies can be avoided.

[0016] In a possible design, the body further comprises a protection structure, which is arranged on the outer periphery of the electric connection structure outwardly protruding relative to the machine shell.

[0017] Based on the body provided in the embodiment, the protection structure is arranged on the outer periphery of the electric connection structure outwardly protruding relative to the machine shell, so that the damage of the electric connection structure can be reduced.

[0018] In a possible design, the other side of the body is provided with a socket matched with the protection structure.

[0019] Based on the body provided in the embodiment, when two bodies are assembled, the protection structure of one body can be inserted into the socket of the other body, so that the assembly of the two bodies is more compact.

[0020] Based on the same inventive concept, in the multi-user electric energy meter, the second body further comprises a protection structure arranged at the outer periphery of the electric connection structure of the second body for connecting the first body. The side of the first body for electrically connecting the second body is further provided with a socket matched with the protection structure.

[0021] Based on the multi-user electric energy meter provided in the embodiment, when the first body and the second body are assembled, the electric connection structure of the second body can be inserted into the electric connection structure of the first body, and at the same time, the protection structure of the second body can be inserted into the socket of the first body, so that the assembly of the first body and the second body is more compact.

[0022] In a possible design, the body further comprises a buckle and a socket, and the buckle and the socket are located at opposite sides of the body. The buckle and the electric connection structure protruding outward relative to the shell are located at the same side of the body, and the socket and the electric connection structure located in the shell are located at the same side of the body.

[0023] Based on the body provided in the embodiment, when two bodies are assembled, when the electric connection structure protruding outward relative to the shell of one body is inserted into the electric connection structure located in the shell of the other body, the buckle is simultaneously inserted into the socket, so that the electric connection of the two bodies is realized at the same time as the buckle connection.

[0024] Based on the same inventive concept, in the multi-user electric energy meter, the second body further comprises a buckle arranged at the side of the second body for connecting the first body. The first body further comprises a socket matched with the buckle, and the socket is arranged at the side of the first body for connecting the second body. In this way, when the first body and the second body are connected, the electric connection structure of the second body is inserted into the electric connection structure of the first body, and at the same time, the buckle of the second body is buckled into the socket of the first body, so that the electric connection of the first body and the second body is realized, and the buckling of the first body and the second body is also realized. In this way, some malicious damage can be avoided.

[0025] In addition, in the present application, the buckle and the electric connection structure protruding outward relative to the shell are located at the same side of the body, and the socket and the electric connection structure located in the shell are located at the same side of the body. This structure is arranged more ingeniously, and can realize the electric connection and mechanical buckling of the two bodies at the same time. BRIEF DESCRIPTION OF DRAWINGS

[0047] Please combine Figure 1 , Figure 3 and Figure 4 , or Figure 1 , Figure 5 and Figure 6 , in the present application, the body 11 can also be a slave 11B, the electrical connection structure includes the pin 111 and the socket 112, and the pin 111 and the socket 112 are arranged on opposite sides of the body 11.

[0048] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the body 11 can be a master 11A in the multi-user electric energy meter 1, the master 11A serves as a central control unit, which is responsible for managing multiple slaves 11B and communicating with external systems (such as power companies or property management systems). The side of the master 11A for connecting the slave 11B is provided with the pin 111. The slave 11B is used to connect the measurement device of each user circuit and is responsible for the specific user's electric quantity metering.

[0050] In addition, the opposite sides of the slave 11B are provided with the pin 111 and the socket 112, and the slave 11B of this structure can use the same structure when used for assembling the multi-user electric energy meter 1. The multiple single-phase slaves used and the multiple three-phase slaves used can also use the same structure, so that the design and production of the slave 11B are facilitated, and the assembly of the multi-user electric energy meter 1 is also facilitated.

[0051] Please combine Figure 1 , Figure 3 and Figure 4 , in an embodiment of the present application, the body 11 can be a single-phase slave, which is mainly used for measuring and recording the power consumption of a single-phase power user.

[0052] Please refer to Figure 1 , Figure 5 and Figure 6 , in an embodiment of the present application, the body 11 can also be a three-phase slave machine, which is mainly used for measuring and recording the power consumption of a three-phase power user.

[0053] It can be understood that Figures 2 to 6 The body 11 shown in the drawings is an embodiment of the present application and does not limit the present application. In some embodiments of the present application, when the body 11 is the master machine 11A, the side of the master machine 11A connected to the slave machine 11B can also be provided with the pin 111. In some embodiments of the present application, when the body 11 is the last slave machine 11B cascaded by the multi-user electric energy meter 1, the slave machine 11B can be provided with the electrical connection structure only on one side.

[0054] Based on the same inventive concept, the present application also provides a multi-user electric energy meter 1, Figure 7 is a right view of Figure 1 is an A-A sectional view of Figure 8 . Figure 7

[0055] Please refer to Figure 1 , Figure 7 and Figure 8 , the multi-user electric energy meter 1 provided by the present application includes at least two bodies 11, the body 11 includes an electrical connection structure, the electrical connection structure includes at least one of the pin 111 and the socket 112. The adjacent two bodies 11 are electrically connected through the insertion of the pin 111 and the socket 112.

[0056] It can be understood that in the present application, one of the adjacent two bodies 11 can be a master machine 11A, and the other can be a slave machine 11B. The adjacent two bodies 11 can also be slave machines 11B.

[0057] Please continue to refer to Figure 1 and Figure 8 , Figure 1 and Figure 8 is a constituent structure diagram of a three-user electric energy meter, which includes four bodies 11, one of which is a master machine 11A and three of which are slave machines 11B. The four bodies 11 are arranged side by side, and the electrical connection between the adjacent two bodies 11 is realized through the insertion of the pin 111 and the socket 112.

[0058] In Figure 1 and Figure 8 ​In the shown structure, the host 11A is provided with a socket 112 on one side, and each of the three slaves 11B is provided with a pin 111 and the socket 112, which are arranged on opposite sides of the slave 11B. When assembling the three-user electric energy meter, the host 11A and the three slaves 11B are electrically connected by plugging the pin 111 and the socket 112.

[0059] It should be noted that, Figure 1 and Figures 3 to 6 is only one embodiment provided by the present application, which aims to illustrate the typical structure of the connection between the bodies 11 in the multi-user electric energy meter 1 through the socket 112 and the pin 111, and does not limit the structure of the multi-user electric energy meter 1 of the present application. In actual application, the composition of the multi-user electric energy meter 1, the structure of the host 11A and the slave 11B can be different from the structure shown in the figure. Figure 3

[0060] For example, in actual application, the number of slaves 11B of the multi-user electric energy meter 1 can be other numbers, such as two, five or more. The plurality of slaves 11B can all be single-phase slaves, or all be three-phase slaves, or be a combination of single-phase slaves and three-phase slaves.

[0061] The electrical connection structure for the host 11A to electrically connect with the slave 11B can also be a pin 111, and correspondingly, the electrical connection structure for the slave 11B to electrically connect with the host 11A is a socket 112.

[0062] For another example, the electrical connection structures arranged on opposite sides of some slaves 11B can all be pins 111, and the electrical connection structures arranged on opposite sides of other slaves 11B can all be sockets 112. When assembling the multi-user electric energy meter 1, the pins 111 and the sockets 112 can be selected and matched according to the plugging relationship.

[0063] In summary, compared with the prior art, the multi-user electric energy meter provided by the present application eliminates the connection wires between adjacent bodies, and directly realizes electrical connection between adjacent bodies through hard connection of pins and sockets, so that the connection between bodies is more convenient and reliable, which helps to improve the data transmission and communication quality between bodies.

[0064] Please continue to refer to Figure 4 In some embodiments of the present application, the body 11 is a slave, and the body 11 includes a casing 113, one of the pin 111 and the socket 112 is located in the casing 113, and the other of the pin 111 and the socket 112 is protruded outward relative to the casing 113.

[0065] Specifically, please refer to Figure 5 and Figure 6 , or refer to Figure 8 and​Figure 2 In some embodiments of the present application, the socket 112 on one side of the body 11 is located inside the casing 113, and the pin 111 on the other side of the body 11 is protruded outside the casing 113.

[0066] In some other embodiments of the present application, the pin 111 on one side of the body 11 is located inside the casing 113, and the socket 112 on the other side of the body 11 is protruded outside the casing 113.

[0067] Please continue to refer to Figure 3 Based on the same inventive concept, the present application also provides a multi-user electric energy meter 1 using the above-mentioned body 11. One of the two adjacent bodies 11 is a first body, and the other of the two adjacent bodies 11 is a second body. The first body includes a first casing, and the electrical connection structure for connecting with the second body is located inside the first casing. The second body includes a second casing, and the electrical connection structure for connecting with the first body is protruded outside the second casing. The electrical connection structure for connecting with the first body of the second body is inserted into the first casing.

[0068] Please combine Figure 8 , Figure 4 with Figure 5 , or Figure 8 , Figure 8 with Figure 3 In some embodiments of the present application, the socket 112 on one side of the body 11 is located inside the casing 113, and the pin 111 on the other side of the body 11 is protruded outside the casing 113. Thus, when the two adjacent bodies 11 are connected, the pin 111 of the second body is inserted into the socket 112 of the first body, and at the same time, the pin 111 of the second body is also inserted into the casing 113 of the first body. In this way, the connection between the first body and the second body is more compact, and the installation space is more saved.

[0069] In addition, please continue to refer to Figure 5 The side of the first body and the second body provided with the electrical connection structure is usually a flat surface. When the pin 111 of the second body is inserted into the casing 113 of the first body, in some cases, the gap between the two adjacent bodies 11 is very small, and seamless connection can be achieved. In this way, not only the installation space can be saved, but also the falling of foreign matters between the two adjacent bodies 11 can be avoided.

[0070] Based on similar principles, the technical solution that the pin 111 on one side of the body 11 is located inside the casing 113, and the socket 112 on the other side of the body 11 is protruded outside the casing 113, when used in the multi-user electric energy meter 1, can also achieve the same technical effects as described above, which will not be repeated here.

[0071] Please refer to Figure 4 or Figure 6In some embodiments of the present application, the body 11 further comprises a protective structure 114, which is arranged at the outer periphery of the outwardly protruding electrical connection structure of the shell 113.

[0072] Specifically, the body 11 of the multi-user electric energy meter 1 needs to go through production, transportation, assembly and other links. In these links, it is sometimes unavoidable to bump and squeeze the body 11. When bumping and squeezing occurs, the outwardly protruding part relative to the main part is usually the most damaged area. Based on this, the present application sets the protective structure 114 at the outer periphery of the outwardly protruding electrical connection structure of the shell 113. In this way, the damage to the electrical connection structure can be reduced.

[0073] Please refer to Figure 4 Or Figure 5 In some embodiments of the present application, the other side of the body 11 is provided with a socket 115 matched with the protective structure 114.

[0074] Specifically, please refer to Figures 2 to 8 And Figure 8 The protective structure 114 is arranged on one side of the body 11, and the socket 115 matched with the protective structure 114 is arranged on the other side of the body 11. In this way, when two bodies 11 are assembled, the protective structure 114 of one body 11 can be inserted into the socket 115 of the other body 11, so that the assembly of the two bodies 11 is more compact.

[0075] Based on the same inventive concept, please refer to Figure 8 In the multi-user electric energy meter 1 provided by the present application, the second body further comprises a protective structure 114, which is arranged at the outer periphery of the electrical connection structure of the second body for connecting with the first body. The side of the first body for electrical connection of the second body is further provided with a socket 115 matched with the protective structure 114. In this way, when the first body and the second body are assembled, the electrical connection structure of the second body can be inserted with the electrical connection structure of the first body, and at the same time, the protective structure 114 of the second body can also be inserted into the socket 115 of the first body, so that the assembly of the first body and the second body is more compact.

[0076] Please continue to refer to Figure 3 In Figure 4 The electrical connection structure of the second body for connecting with the first body is a pin 111, and the outer periphery of the pin 111 is provided with a protective structure 114. The electrical connection structure of the first body for connecting with the second body is a socket 112, and the shell 113 at the socket 112 is provided with a socket 115.

[0077] In some embodiments of the present application, the electric connection structure of the second body for connecting with the first body is also the socket 112, and the outer periphery of the socket 112 is provided with the protection structure 114. The electric connection structure of the first body for connecting with the second body is the pin 111, and the shell 113 at the pin 111 is provided with the socket 115.

[0078] Please refer to Figure 5 and Figure 6 , or Figures 2 to 8 and Figure 8 In some embodiments of the present application, the body 11 further comprises the buckle 116 and the buckle hole 117, and the buckle 116 and the buckle hole 117 are located on opposite sides of the body 11. Among them, the buckle 116 and the electric connection structure protruding outward relative to the shell 113 are located on the same side of the body 11, and the buckle hole 117 and the electric connection structure located in the shell 113 are located on the same side of the body 11. Thus, when two bodies 11 are assembled, the electric connection structure protruding outward relative to the shell 113 on one body 11 is inserted into the electric connection structure located in the shell 113 of the other body 11, and the buckle 116 on one body 11 is simultaneously buckled with the buckle hole 117 of the other body 11. Thus, the two bodies 11 realize electric connection and buckle connection at the same time.

[0079] Based on the same inventive concept, please continue to refer to Figure 1 In the multi-user electric energy meter 1 provided by the present application, the second body further comprises the buckle 116, and the buckle 116 is arranged on the side of the second body for connecting with the first body. The first body further comprises the buckle hole 117 matched with the buckle 116, and the buckle hole 117 is arranged on the side of the first body for connecting with the second body.

[0080] Specifically, please continue to refer to Figure 2 In some embodiments of the present application, the electric connection structure of the first body for connecting with the second body is located in the first shell. The electric connection structure of the second body for connecting with the first body protrudes outward relative to the second shell. The side of the first body for connecting with the second body is provided with the buckle hole 117, and the side of the second body for connecting with the first body is provided with the buckle 116. Thus, when the first body and the second body are connected, the electric connection structure of the second body is inserted into the electric connection structure of the first body, and at the same time, the buckle 116 of the second body is buckled with the buckle hole 117 of the first body. Thus, the electric connection of the first body and the second body is realized, and the buckling fixation of the first body and the second body is also realized, and the buckling of the first body and the second body can avoid the loosening and falling off of the electric connection structure of the first body and the second body.

[0081] In addition, in the actual use of the multi-user electric energy meter 1, the malicious destruction of the electrical connection between two bodies 11 can occur. The buckle 116 and the clamping hole 117 can be arranged on the body 11 to connect the buckles 116 of two adjacent bodies 11, so that malicious destruction can be avoided.

[0082] In addition, in the present application, the buckle 116 and the electrical connection structure protruding outward relative to the shell 113 are located on the same side of the body 11, and the clamping hole 117 and the electrical connection structure located in the shell 113 are located on the same side of the body 11. This structure is cleverly arranged, and the electrical connection and mechanical clamping fixation of two bodies 11 can be realized at the same time during the assembly of the multi-user electric energy meter 1.

[0083] Please combine Figure 3 , Figure 1 and Figure 4 , or Figure 5 , ​ and ​ , in some embodiments of the present application, the number of buckles 116 on one side of the body 11 can be one, two or more, and correspondingly, the number of clamping holes 117 on the other side of the body 11 can also be one, two or more.

[0084] For example, in an embodiment, a plurality of bodies 11 are arranged in combination along the first direction D1, two buckles 116 are arranged on one side of the body 11 along the second direction D2, and the two buckles 116 are located at opposite ends of the second direction D2 of the body 11. Correspondingly, two clamping holes 117 are arranged on the other side of the body 11 along the second direction D2, and the two clamping holes 117 are located at opposite ends of the second direction D2 of the body 11. When two bodies 11 are assembled, the two buckles 116 of one body 11 can be correspondingly clamped with the two clamping holes 117 of the other body 11, so that the two bodies 11 can be combined more tightly and reliably, and in the second direction D2, the two buckles 116 can limit the relative position of the first body and the second body, and the relative position of the first body and the second body is more stable.

[0085] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments means that it is within the scope of the present application and forms different embodiments.
