Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage electrical technology, specifically to a measurement switch with high space utilization. Background Technology
[0002] In power distribution systems, measuring switches integrate multiple functions such as traditional circuit breakers, energy metering, condition monitoring, and communication, making them a key component of modern smart grids. With increasingly complex functions, the main design challenge lies in how to rationally arrange these functional components within a limited space and achieve flexible configuration and convenient maintenance of functional modules.
[0003] The functional components of existing measuring switches (such as metering modules and communication modules) are usually soldered or connected to the main board with complex cables. This structure has the following disadvantages: 1) Low utilization of internal space, insufficient isolation between components of different voltage levels, and potential safety hazards; 2) Fixed functions, making it impossible to flexibly add, remove, or replace modules according to field requirements; 3) Difficult maintenance, as damage to a single module often requires complete disassembly or replacement of the entire unit, resulting in high costs and long time consumption.
[0004] To address the aforementioned drawbacks, existing structures employ pluggable functional components. However, because these structures directly install mounting slots on the base, each functional component is directly plugged into and unplugged into the slot. To achieve electrical connection between the functional components and the internal wiring, a functional adapter board is typically installed directly within the mounting slot. The functional modules are directly plugged into and unplugged into the functional adapter board. This approach leaves the functional adapter board exposed, making it susceptible to damage from the plugging and unplugging of functional components, which can lead to problems with the functional adapter board. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a measurement switch with high space utilization.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A measurement switch with high space utilization includes:
[0008] A base, wherein the base is provided with several independent phase wire channels;
[0009] A base, covering the base, has mounting slots on its upper surface for mounting multiple functional modules;
[0010] A protective cover can be opened to cover the mounting slot;
[0011] A function board is located below the base, and the function board is provided with an interface;
[0012] A protective base is disposed between the base and the pedestal, and together with the pedestal, forms an installation chamber for accommodating the functional panel;
[0013] The mounting slot has an opening at the bottom, through which the interface is exposed. The functional module is installed in the mounting slot in a pluggable manner and forms a pluggable electrical connection with the interface.
[0014] The protective base has at least two bearing surfaces, which are parallel to each other and located in different planes.
[0015] The bearing surface includes a first bearing surface and a second bearing surface. The first bearing surface is located above the tripping assembly, and the second bearing surface is located above the outgoing line.
[0016] The mounting chamber includes a first mounting chamber and a second mounting chamber, wherein the first mounting chamber is located between the first bearing surface and the base, and the second mounting chamber is located between the second bearing surface and the base.
[0017] The bottom surface of the first bearing surface extends downward to form a plurality of first partitions, which are used to isolate each phase line channel.
[0018] The connection between the first bearing surface and the second bearing surface extends downward to form a second partition, which is used to isolate the outgoing side and the operating side.
[0019] One end of the protective cover is rotatably mounted on the base, and the other end is detachably and fixedly connected to the base.
[0020] The connection between the protective cover and the base is provided with a lead seal structure.
[0021] The bottom surface of the base is provided with an installation space for mounting a trigger plate. The trigger plate is provided with multiple trigger switches, and each trigger switch is respectively set to correspond one-to-one with each corresponding phase wire channel. Each trigger switch extends into the corresponding phase wire channel and is located on the rotation path supported by the contact.
[0022] The beneficial effects of this utility model are as follows: by setting protective seats with different bearing surfaces, a three-dimensional installation chamber is effectively opened above large-volume components such as tripping components and outgoing terminals to accommodate functional boards with different functions. This achieves full utilization of the three-dimensional space inside the switch, making the overall structure very compact. At the same time, the functional boards are internally protected so that they are not directly exposed to contact with functional components.
[0023] Meanwhile, the mounting slot on the base is directly connected to the interface on the function board, allowing function modules (such as 4G communication modules, LCD display modules, metering chip modules, etc.) to be directly inserted into the mounting slot like "cards" and electrically connected. Replacing or upgrading modules does not require disassembly or soldering, making the operation simple and quick, greatly reducing maintenance costs and difficulty. Attached Figure Description

[0030] 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.
[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain a specific posture (as shown in the attached figure).
[0032] like Figure 1 and Figure 2 As shown, this utility model discloses a measuring switch with high space utilization, which includes a base 100, a base 200 covering the base 100, a protective cover 400, and a top cover 300. The space formed by the base and the base contains the components required to constitute the measuring switch, such as terminals located at both ends of the base, outgoing lines arranged sequentially along the length of the base, a backup protection mechanism, an operating mechanism that drives the moving contact, a stationary contact, and an arc-extinguishing chamber. A current transformer and a metering transformer are sequentially mounted on the outgoing lines.
[0033] The base 100 serves as the support foundation for the switch, and its interior is equipped with multiple independent phase wire channels 110 for accommodating and isolating the conductive circuits of each phase (such as outgoing lines, backup protection mechanisms, operating mechanisms that drive the moving contacts, stationary contacts, and arc-extinguishing chambers).
[0034] The protective base 700 is fixedly mounted to the base 100 by clips or screws. See also Figure 3 and Figure 6 The protective base 700 is integrally injection molded, and its main structure includes a first bearing surface 710 and a second bearing surface 720 located on different planes. The first bearing surface 710 is positioned higher, corresponding to the area above the tripping assembly 20 on the base 100, and cooperates with the base to clamp and position the mounting plate of the tripping assembly. The second bearing surface 720 is positioned lower, corresponding to the area above the outgoing line 10 on the base 100. At the bottom of the first bearing surface 710, multiple parallel first partitions 730 extend downwards. These first partitions 730 cooperate precisely with the side walls of each phase line channel 110 on the base 100, serving as phase-to-phase isolation. At the transition between the first bearing surface 710 and the second bearing surface 720, a transverse second partition 740 extends downwards. This partition 740 roughly divides the internal space of the switch into a rear "operating side" (including the tripping assembly 20, operating mechanism, etc.) and a front "outgoing line side." "Front" and "rear" refer to... Figure 3 The left and right sides of the middle paper.
[0035] The base 200 covers and is fixed above the protective base 700. At least one mounting slot 210 is formed on the upper surface of the base 200. The size of the mounting slot 210 matches the shape of the functional module to be installed. In this embodiment, to accommodate the functional board in conjunction with the protective base, the mounting slots are divided into two groups, one group being deeper than the other. The deeper group is located above the second bearing surface, and the shallower group is located above the first bearing surface. The deeper group is used to place the measurement module 500, while the shallower group is used to place the metering module 600, thus optimizing the size of different modules and making the best use of internal space. Each mounting slot 210 has a through hole at its bottom, the position of which is precisely aligned with the interface 910 on the functional board 900 below.
[0036] A protective cover 400 can be opened to cover the mounting slot 210;
[0037] Functional board 900 is a printed circuit board (PCB) that integrates the corresponding circuitry. For example... Figure 4 As shown, the function board 900 is fixed to the various bearing surfaces of the protective base by screws or clips. The function board 900 is provided with multiple standardized interfaces 910, such as board-to-board connectors and pin headers.
[0038] A protective base 700 is disposed between the base 100 and the base 200, and together with the base 200, forms an installation chamber 1000 for accommodating the functional plate 900;
[0039] The mounting slot 210 has an opening at its bottom, through which the interface 910 is exposed. The functional module is installed in the mounting slot 210 in a pluggable manner and forms a pluggable electrical connection with the interface 910.
[0040] like Figure 5 As shown, after assembly, a first mounting chamber is formed between the first bearing surface 710 of the protective seat 700 and the lower surface of the base 200, and a second mounting chamber is formed between the second bearing surface 720 of the protective seat 700 and the lower surface of the base 200. The main body of the functional board 900 is then accommodated and protected within these two mounting chambers 1000 formed by the protective seat 700 and the base 200. This "double-layer" chamber design cleverly "mounts" the functional board 900 above the tripping assembly 20 and the cable outlet, making full use of the vertical space of these components and achieving a compact three-dimensional layout.
[0041] When adding or replacing functions to the switch, the operator simply needs to open the protective cover 400. One end of the protective cover 400 is hinged to the base 200 via a pivot, and the other end is secured with clips or screws and can be sealed with a lead seal. After opening the protective cover 400, the various mounting slots 210 are exposed. The user can directly insert the corresponding functional module vertically into a mounting slot 210. The connectors (such as gold fingers or plugs) at the bottom of the module will reliably mate with the corresponding interfaces 910 on the function board 900 through the openings at the bottom of the mounting slot 210, instantly completing the electrical connection and mechanical fixation. The entire process requires no tools for internal wiring, achieving true "plug and play".
[0042] In addition, a mounting space 2000 is reserved on the bottom surface of the base 100 for mounting a trigger plate 800. The trigger plate 800 is equipped with several microswitches or optocouplers, each trigger switch being located in a corresponding phase line channel 110 and near the rotation path supported by the phase contact. When the switch performs an opening or closing operation, the rotation supported by the contact will press or release the corresponding trigger switch, thereby generating an electrical signal.
[0043] Meanwhile, a top cover is provided at the location of the non-installation slot of the base. The top cover has a space for the handle of the operating mechanism to pass through. The top cover and base are detachable, which ensures that when the measuring switch has a single handle or a three-handle, only the top cover needs to be replaced to switch between different handles, without having to replace the base, thus reducing the amount of base stock required.
[0044] The present invention utilizes the unique structure of the protective base 700 to install the functional board 900 three-dimensionally on the upper layer of the internal space and directly connect it with the modular mounting slot 210 on the base 200. Under the premise of ensuring strict electrical isolation, it achieves extremely high space utilization and unparalleled modular expansion and maintenance convenience.
[0045] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
