DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0029] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indications also change accordingly.

[0030] The utility model provides a kind of multi-user splicing electric energy meter.

[0031] In the present embodiment, refer toFigures 1-8 The multi-user spliced electric energy meter comprises a meter one 1 and a meter two 2, both of which comprise a bottom shell 3 and an upper cover 4 covering the bottom shell 3, both ends and the middle part of the adjacent bottom shell side walls of the meter one 1 and the meter two 2 are respectively provided with two fixing holes 5, the inner side wall of the bottom shell at the fixing holes 5 is provided with a sunken hole 6, and the middle part of the bottom shell side wall is provided with a wire passing hole group for connecting the meter one and the meter two.

[0032] In the above technical solution, the fixing hole and the sunken hole are arranged on the adjacent bottom shell side walls of the meter one and the meter two, after splicing, the meter one and the meter two are fixed by using the bolt passing through the fixing hole and the nut, thereby realizing the rapid splicing and stable connection of the electric energy meter. The design of the sunken hole enables the bolt head to be hidden in the electric meter, avoiding the influence of the exposed bolt on the appearance of the meter shell, and making the appearance of the electric meter more neat and beautiful. In addition, the wire passing hole group is used for wiring between the meters, so that the wiring between the meters is hidden in the meter shell, avoiding the disorderly arrangement of the lines, and helping to fully utilize the space inside the electric meter box, so that the whole system is more compact.

[0033] Specifically, the wire passing hole group comprises five holes, including a first wire passing hole 7 arranged between the two fixing holes in the middle part of the bottom shell and a second wire passing hole 8 arranged on both sides of the first wire passing hole 7.

[0034] In the above technical solution, the wire passing hole group is arranged in multiple holes, which ensures the convenience and reliability of the wire connection between the meter one and the meter two. The distribution of the five wire passing holes can effectively reduce the crossing and winding of the wires, making the wire layout more reasonable and facilitating maintenance and inspection.

[0035] Specifically, the bottom shell of the meter one 1 and the meter two 2 is provided with a large current wiring assembly on one end opening and a wire outlet base 9 on the other end opening, the wire outlet base 9 is provided with a plurality of wire connection ports 10 and a wire terminal assembly 11, the large current wiring assembly comprises a wire inlet base 12 and a wire copper plate 15 fixed in a wire slot 14 of the wire inlet base 12 through a wire bolt 13, the back surface of the wire slot is provided with a through slot 16 for the wire copper plate to pass through, and a plurality of wire connection holes 17 are arranged on one end of the wire copper plate away from the wire bolt.

[0036] By arranging different wiring assemblies, i.e. a large current wiring assembly and a wire outlet base, on both ends of the bottom shell, the electric energy meter is more convenient when connecting and outputting current. Such design not only simplifies the wiring process, but also improves the safety of wiring.

[0037] In addition, the traditional electric energy meter mainly considers the small current application in the household power environment in the design, and the connection port at both ends thereof can usually only bear a relatively small current. In order to accurately measure the electric energy in a large current environment, a current transformer is usually required to be installed in front of the electric energy meter. However, the incoming line end of the present application adopts a large current connection assembly, and the electric energy meter can be directly connected to a large current line, thereby avoiding the necessity of using a transformer, simplifying the system structure, and improving the practicability and cost-effectiveness of the electric energy meter.

[0038] In the large current connection assembly, the main medium adopts a connection copper plate, which can bear a larger cable. The thickness of the connection copper plate is between 3.5-5 mm, and can bear a large current of 350-600 AD. Therefore, the electric energy meter does not need to be additionally installed with a transformer.

[0039] Specifically, the two sides of the connection slot 14 are provided with connecting screw holes 18, and threaded connection studs 19 are screwed into the connecting screw holes 18. The two sides of the connection copper plate are provided with positioning screw holes 20 which are screwed with the connection studs.

[0040] By arranging the connecting screw holes on both sides of the connection slot and connecting the connection studs with the positioning screw holes on the connection copper plate, the structure design ensures the firm fixing of the connection copper plate in the connection slot, and enhances the stability and reliability of the connection.

[0041] Specifically, the bottom shell is provided with a first positioning slot 21, the incoming line base and the outgoing line base are provided with second positioning slots 22 which are in communication with the first positioning slot 21, the upper cover is provided with a first positioning boss 23 which is clamped with the first positioning slot and the second positioning slot, the two sides of the second positioning slot are provided with third positioning slots 24, and the two sides of the opening are provided with second positioning bosses 25 which are clamped with the third positioning slots 24.

[0042] After the incoming line base is installed on the opening of the bottom shell, the incoming line base is in the same height with the bottom shell, so that the first positioning slot and the second positioning slot are continuous annular positioning slots which can be clamped with the first positioning boss on the upper cover, thereby playing a positioning role and improving the dustproof and waterproof effects. In addition, the third positioning slots on both sides of the second positioning slot are arranged to cooperate with the second positioning bosses on both sides of the opening, and are used for the installation and clamping of the incoming line base.

[0043] Specifically, the two ends of the upper cover are provided with rotating shafts 26, and rotating clamping flaps 27 for covering the opening are connected to the rotating shafts 26.

[0044] The clamping flaps on the rotating shafts of the two ends of the upper cover can be conveniently opened or closed by the user, which not only facilitates the connection operation, but also provides additional protection, thereby avoiding the risk of damage to the connection part caused by external factors.

[0045] Skilled technicians should know: although the utility model has been described in the above specific embodiments, the utility model idea is not limited to this utility model, any modification using the utility model idea will be included in the patent protection range.
