[0002] Electricity metering boxes are key equipment in power systems used to centrally install electricity meters and related electrical components. The rationality of their structure directly affects metering accuracy, operational safety, and ease of maintenance. Currently, common electricity metering boxes typically consist of a casing and a door. The casing is divided into several sections for installing electricity meters by partitions, and fixed wiring holes are opened at the bottom of the box for wiring to pass through.
[0003] However, the aforementioned traditional structure has significant drawbacks: First, because the wiring holes are fixed, installers must first fix the mounting plate or components inside the enclosure, and then perform wiring operations within the confined space of the enclosure. This is not only inefficient, but also prone to loosening or errors due to the inconvenience of operation, affecting wiring quality and the reliability of future operation. Second, all wires are threaded through one or a group of fixed holes. Multiple wires are easily tangled and squeezed together at the holes and inside the enclosure, resulting in tight contact between the wires, which is not conducive to heat dissipation and may generate electromagnetic interference, affecting measurement accuracy.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-6 As shown, an embodiment of the present invention provides an energy metering box, comprising a housing 1, a cavity 10 inside the housing 1 and a door 11 hinged to its front side, a plurality of partitions 12 are installed at intervals inside the housing 1, dividing the cavity 10 into a plurality of assembly sections 13 by the partitions 12; an installation opening 2 is formed at the bottom of the housing 1 at the corresponding position of each assembly section 13; a baffle 20 is installed at each installation opening 2, and the baffle 20 is detachably disposed in the installation opening 2; at least one wiring port 21 is formed between the baffle 20 and the installation opening 2; a branching unit 3 is provided on the upper surface of the baffle 20 at the corresponding position of the wiring port 21, and the branching unit 3 is configured to separate the lines passing through the wiring port 21.
[0019] In use, the detachable baffle 20 changes the traditional installation sequence, allowing components to be pre-installed and wired outside the enclosure before being installed as a whole. This not only greatly improves the convenience and efficiency of installation and subsequent maintenance, but also ensures the quality of wiring. At the same time, the branching unit 3 located above the baffle 20 can effectively separate the lines passing through the wiring port 21, avoiding problems such as insulation wear, poor heat dissipation and electromagnetic interference caused by mutual compression and entanglement between lines, thereby significantly improving the safety and reliability of equipment operation.
[0020] The left and right sides of the baffle 20 are formed with bent portions 22, and the bent portions 22 and the baffle 20 body form side grooves 23; the left and right sides of the mounting opening 2 are adapted to the side grooves 23; the inner side of the mounting opening 2 is formed with two slots 24; the insertion end of the baffle 20 is formed with two extensions 25 adapted to the slots 24; the outer sides of the left and right ends of the baffle 20 are formed with limiting portions 26 at the corresponding positions of the slots 24.
[0021] In use, the buckling between the bent part 22 and the upper edge of the mounting opening 2, the insertion and engagement between the extension part 25 and the slot 24, and the constraint of the limiting part 26 together form a stable limiting effect. This structure not only achieves reliable constraint of the baffle 20 in the vertical direction, effectively preventing loosening or displacement during use, but also makes the installation and disassembly of the baffle 20 extremely simple, requiring only horizontal pushing or pulling, greatly improving the efficiency of assembly and maintenance.
[0022] Each slot 24 has a limiting block 27 formed inside; each limiting block 27 has a guide slope 28 formed on the side near the insertion end of the slot 24; each extension 25 has a slot 29 that is adapted to the limiting block 27.
[0023] In use, a clever latching and limiting mechanism is formed by setting a limiting block 27 with a guide slope 28 in the slot 24 and a corresponding slot 29 on the extension 25. On the one hand, the guide slope 28 guides the insertion process of the baffle 20, so that it can be inserted smoothly and effortlessly; on the other hand, when the baffle 20 is pushed to the final position, the slot 29 and the limiting block 27 automatically engage, realizing reliable locking of the baffle 20 in the horizontal pulling direction, effectively preventing it from loosening due to vibration or accidental contact, and further enhancing the stability and safety of the connection.
[0024] At least one first semi-circular groove 4 is formed on the edge of the mounting opening 2; a second semi-circular groove 40 is formed at the corresponding position of the baffle 20; when the baffle 20 is installed in the mounting opening 2, the first semi-circular groove 4 and the second semi-circular groove 40 surround each other to form a wiring port 21.
[0025] When in use, the semi-circular groove design is easy to manufacture and can form neat wiring ports 21, which is beneficial for line protection and avoids line wear.
[0026] The dividing unit 3 includes a fixed seat 30, a positioning seat 31, and a dividing component; the fixed seat 30 is installed on the upper surface of the baffle 20, and the fixed seat 30 has a strip-shaped structure with a through groove 32 formed in the center; the positioning seat 31 is slidably disposed in the through groove 32; the dividing component is installed on the positioning seat 31 and includes a horizontal plate 33 and a plurality of dividing rods 34 disposed on the horizontal plate 33.
[0027] In use, the sliding positioning seat 31 design gives the branching unit 3 flexible adjustability. The installer can slide the dividing rod 34 to the most reasonable position to effectively divide the line according to the actual situation of the line to be inserted, which significantly improves the practicality and reliability of the equipment. See the attached instruction manual. Figure 4 The mounting base 30 is designed as a detachable structure. Specifically, mounting ears are provided on both the left and right sides of the mounting base 30. Through holes are provided on the mounting ears. The external fastener is passed through the through holes and tightened with the threaded hole 53 on the upper surface of the baffle 20 to install and fix the mounting base 30. When it is necessary to disassemble the mounting base 30, the opposite operation is performed.
[0028] Two racks 35 are symmetrically arranged on the inner walls of the left and right sides of the through groove 32; a plurality of first locking teeth 36 are arranged in an array on the lower surface of each rack 35, and a limiting groove 37 is formed between adjacent first locking teeth 36; a sliding interval is formed between the two racks 35; the positioning seat 31 includes a sliding part 5 and a positioning part 50, the sliding part 5 is adapted to the sliding interval, and the positioning part 50 is adapted to the through groove 32; the positioning part 50 is provided with locking ribs 51 adapted to the limiting groove 37; two elastic pieces 52 are symmetrically arranged on the left and right sides of the top surface of the sliding part 5; in the natural state, each elastic piece 52 bends downward from the inside to the outside and abuts against the upper end face of the corresponding rack 35; each elastic piece 52 is adapted to the width of the through groove 32.
[0029] When adjusting the position of the dividing unit 3, simply press down on the positioning seat 31 to overcome the elastic force of the elastic piece 52, causing the retaining rib 51 on the positioning part 50 to disengage from the limiting groove 37 on the rack 35. Then, the positioning seat 31 can be slid left and right along the through groove 32 to the desired position. After releasing, the rebound force of the elastic piece 52 will push the positioning seat 31 upward, automatically causing the retaining rib 51 to re-engage in the limiting groove 37 of the rack 35, achieving precise locking. This "press to unlock, slide to position, release to lock" operation method requires no tools and can be completed with one hand. The adjustment process is efficient, intuitive, and reliable. In addition, the notch formed between the two racks 35 and the side wall of the through groove 32 provides a channel for the overall installation and disassembly of the positioning seat 31 and the dividing component, greatly facilitating daily maintenance and replacement.
[0030] A threaded hole 53 is provided at the center of the top surface of the sliding part 5; a fastening hole 54 corresponding to the threaded hole 53 is provided on the horizontal plate 33; the horizontal plate 33 is fixed to the sliding part 5 by an external fastener that passes through the fastening hole 54 and engages with the threaded hole 53.
[0031] During use, the fastener connection makes it easy to install and replace the separator component and the positioning seat 31, which is convenient for maintenance and reduces maintenance costs.
[0032] The specific working process of this utility model is as follows: First, the components such as the electricity meter are pre-installed and wired on the outside of the housing and the mounting base plate composed of the partition 12; after completion, the entire assembly is installed into the corresponding assembly section 13 of the cavity 10 of the housing 1; then, the baffle 20 is pushed into the mounting opening 2 at the bottom of the housing 1 in the horizontal direction, the bent parts 22 on both sides of the baffle 20 are engaged with the upper edge of the mounting opening 2, the extension part 25 is inserted into the slot 24 until the limiting block 27 is engaged with the slot 29, so as to reliably fix the baffle 20. At this time, the baffle 20 and the semi-circular groove on the mounting opening 2 form a regular wiring port 21; according to the number and distribution of the wiring port 21, the positioning seat 31 of the branch unit 3 is pressed to unlock it, the sliding adjustment divider 34 is slid to the optimal position and then released, the positioning seat 31 is automatically reset and locked under the action of the elastic piece 52, so as to orderly divide the wiring; the horizontal plate 33 is installed on the positioning seat 31 by fasteners, which facilitates subsequent disassembly and maintenance; the whole process realizes fast, safe and neat installation and wiring.
[0033] In addition, please refer to the instruction manual appendix. Figure 2 This utility model features excellent adaptability and modularity. The size of the installation opening 2 can be adjusted accordingly for different specifications and capacities of power metering boxes. Correspondingly, the baffle 20 can be designed in different sizes, and the number of connection ports 21 and branching units 3 can be flexibly configured. Specifically, for small assembly areas 13, a small baffle 20 with only one connection port 21 and one branching unit 3 can be used; for large or multi-circuit assembly areas 13, a large baffle 20 with multiple connection ports 21 and correspondingly multiple branching units 3 can be selected. This modular design enables the solution to meet various wiring needs from simple to complex, achieving a balance between standardized production and personalized applications.
