Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, specifically to an integrated module and a smart electricity meter. Background Technology

[0002] With the rapid development of electronic technology, the functions of various electronic devices are becoming increasingly complex and integrated. Within the internal structure of electronic devices, various independent functional modules, such as power modules, sensing modules, and control modules, are typically mounted on the main circuit board to achieve specific system functions. These functional modules often require cables for external power input or signal exchange.

[0003] However, in existing electronic equipment assembly structures, the installation of functional modules and the layout of internal leads often lack strict specifications and physical constraints. The conventional assembly practice involves assemblies connecting leads to corresponding interfaces after the functional modules are initially fixed. The leads are then allowed to hang freely or be laid out haphazardly within the remaining space inside the casing. This disordered wiring method reveals significant drawbacks in practical applications: Firstly, unconstrained leads are prone to spatial displacement and continuous shaking during long-distance transportation or prolonged vibration operation. This not only causes frictional damage to the cable insulation layer but also creates repeated mechanical stress concentrations at the cable root and interfaces, significantly increasing the risk of fatigue fracture or loose solder joints. Secondly, the haphazard wiring lacking guidance structures heavily relies on the assembly personnel's skill, resulting in messy internal wiring and extremely poor assembly consistency in mass-produced equipment.

[0004] Furthermore, the aforementioned problems of disordered wiring and loose structure are particularly detrimental in certain functional modules that are highly sensitive to the spatial electromagnetic environment, such as communication modules. Taking smart meters as an example, they typically require a dedicated communication module as a typical and important application scenario to support remote communication interactions such as radio frequency (RF) and GPRS. For such high-frequency communication modules, changes in the spatial orientation and direction of the antenna leads, as well as their distance from surrounding components, can cause drastic fluctuations in the strength of the induced signal and impedance mismatch. Using existing uncontrollable free wiring methods makes the strength of the internal RF signal unpredictable, highly susceptible to interference, and leads to extremely unstable data transmission at the lower levels.

[0005] Therefore, there is an urgent need to develop a completely new structural design to solve the problems of unstable functional module fixing and arbitrary lead routing in existing electronic modules. Summary of the Invention

[0006] This invention provides an integrated module and a smart energy meter to solve the problems of loose modules and arbitrary wiring, thereby achieving the effect of stabilizing the module and standardizing the wiring.

[0007] In a first aspect, the present invention provides an integrated module, comprising: Circuit board; At least one lead, one end of which is electrically connected to the circuit board; A bracket is mounted on the surface of the circuit board and located on one side of the functional module. The bracket is provided with a lead wire guiding structure. The middle section of the lead wire is oriented along the lead wire guide structure so that the lead wire is limited and fixed and forms a preset wiring path.

[0008] Beneficial Effects: By adding a bracket with a lead wire guiding structure, the defects of loose structure and easy electrical connection failure caused by disordered lead wire layout in traditional equipment are overcome. In the specific structural configuration, the bracket is installed on the surface of the circuit board, allowing the lead wires electrically connected to the circuit board to be freed from a free-hanging state. The middle section of the lead wire is oriented and confined within the aforementioned lead wire guiding structure, thus achieving strict physical constraint in space. This structure significantly improves the overall mechanical vibration resistance of the integrated module. When the equipment is under long-distance transportation or long-term vibration operation, the constrained lead wires no longer shift or rub, greatly reducing the risk of cable insulation wear and root interface failure due to stress concentration. In addition, this solution establishes a standardized physical operation benchmark for manufacturing and assembly. Operators only need to follow the guiding structure to lay cables, effectively avoiding the safety hazards of internal wire tangles, and thus ensuring that the integrated modules produced in batches maintain a high degree of consistency in physical assembly form.

[0009] In one optional embodiment, the lead wire guiding structure includes at least one lead wire groove and at least one wire clamping rib distributed along the wiring path. The lead wire groove and the wire clamping rib are respectively disposed on the bracket. The lead wire passes through the lead wire groove, and a portion of the lead wire is pressed and limited by the wire clamping rib.

[0010] In one optional embodiment, the device further includes a base, a cover, and a functional module. The circuit board is fixedly installed inside the base, the cover is placed on the base and detachably fastened to it, the functional module is fixed on the circuit board and electrically connected to the lead wire, the cover and the base together form a receiving cavity, and the circuit board, the functional module, and the bracket are all housed within the receiving cavity.

[0011] In one optional embodiment, a limiting structure for fixing the functional module is further included. The limiting structure includes multiple limiting posts and multiple limiting ribs. The multiple limiting posts are disposed on the inner bottom surface of the box base and extend upward. The upper part of the limiting posts is used to support the bottom surface of the circuit board. The multiple limiting ribs are disposed on the inner top surface of the box cover and extend downward. When the box cover is fastened to the box base, the bottom ends of the multiple limiting ribs press against the top surface of the circuit board, thereby clamping and fixing the circuit board in the vertical direction together with the multiple limiting posts.

[0012] In one optional embodiment, the limiting post is stepped, including a lower limiting segment and an upper limiting segment. The outer diameter of the lower limiting segment is larger than the outer diameter of the upper limiting segment. The top of the lower limiting segment forms a stepped surface for reserving space for installing an adapter circuit board. The circuit board is supported on the upper limiting segment, and the bottom ends of the multiple limiting ribs respectively abut against multiple corresponding points on the top surface of the circuit board.

[0013] In one optional embodiment, the circuit board is provided with a pin socket, and the bracket is provided with a pin sleeve. The inner sidewall of the pin sleeve has a draft angle that slopes inward from bottom to top, so that the inner hole of the pin sleeve forms a contraction opening that is larger at the bottom and smaller at the top. The pin sleeve is fitted onto the outside of the pin socket from top to bottom, and the sidewall of the inner hole of the pin sleeve is in close contact with the outer wall of the pin socket. The housing is provided with a receiving portion for inserting the pin socket, and the inner top surface of the housing cover extends downward with a pressing member. When the housing cover is fastened onto the housing cover, the pressing member presses against the top of the pin sleeve.

[0014] In one optional embodiment, a sealing strip is also included. The edge of the box base has an annular waterproof groove, and the sealing strip is fitted into the waterproof groove. The edge of the box cover has a protruding crimping rib adapted to the waterproof groove. When the box cover is fastened onto the box base, the crimping rib extends into the waterproof groove and presses against the sealing strip to form a waterproof seal at the connection between the box base and the box cover.

[0015] In one optional embodiment, the bracket is provided with a wire fixing area, the box base is fixedly provided with a first external wiring interface, the lead wire includes a first lead wire, the functional module is electrically connected to a first socket, and the plurality of lead wire slots include a first lead wire slot, a second lead wire slot and a third lead wire slot. One end of the first lead wire is inserted into the first socket and the other end is connected to the first external wiring interface. The middle section of the first lead wire is sequentially locked in the first lead wire slot, the second lead wire slot, the bottom side of the wire clamping rib and the third lead wire slot. After the first lead wire passes through the wire fixing area, it bends into a loop shape on the side of the functional module and continues to extend downward to the first external wiring interface.

[0016] In one optional embodiment, a second lead is also included. The functional module is also electrically connected to a second socket. The housing is also fixedly provided with a second external wiring interface. One end of the second lead is inserted into the second socket. The second lead is arranged independently of the lead guide structure and is directly connected to the second external wiring interface.

[0017] Secondly, the present invention also provides a smart energy meter, including a casing and an integrated module, wherein the integrated module is disposed in the casing.

[0018] Beneficial Effects: Integrating the aforementioned integrated module inside the meter housing creates a metering terminal system with standardized internal wiring and a stable structure. Utilizing the physical constraint of the integrated module on the lead wire routing, the combined application of this energy meter and the integrated module provides reliable rigid protection and support for the internal core electronic components and their wiring, effectively overcoming defects such as component loosening or wire harness wear caused by vibration loads during assembly, handling, and long-term grid operation. Furthermore, this overall structural design optimizes the overall production and assembly process of the energy meter, providing standardized execution benchmarks for the fixing of internal modules and the laying of leads, thereby improving the product consistency of mass-produced smart energy meters in terms of structural reliability.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0024] Example 1: As Figure 1-9 As shown, according to an embodiment of the present invention, an integrated module is provided, comprising: Circuit board 2; At least one lead, one end of which is electrically connected to circuit board 2; The bracket 4 is mounted on the surface of the circuit board 2, and the bracket 4 is provided with a lead wire guiding structure 5; The middle section of the lead wire is oriented along the lead wire guide structure 5 so that the lead wire is limited and fixed and forms a preset wiring path.

[0025] In this embodiment, by adding a bracket 4 to the circuit board 2 and installing a lead wire guiding structure 5 on the bracket 4, a clear physical arrangement carrier is provided for the external leads on the circuit board 2. After the leads are electrically connected to the circuit board 2 (or various electronic components mounted on it), their middle sections are oriented and constrained within the lead wire guiding structure 5, thus providing stable spatial support for the flexible cables that are originally prone to deformation or displacement.

[0026] This directional and fixed structural design ensures that the leads are laid strictly according to the preset wiring path, resulting in significant structural advantages. The fixed leads effectively resist stress transmission from external vibration environments, preventing wear of the cable insulation layer due to continuous shaking during long-term operation. It also reduces the risk of mechanical fatigue fracture at the cable connection points, comprehensively improving the reliability of internal electrical connections. Furthermore, the lead guide structure 5 establishes a standardized physical work benchmark for the production assembly process. Assembly personnel only need to arrange the leads along this guide structure to complete standardized wiring, effectively preventing assembly errors such as multiple internal cables crossing, tangling, or being squeezed together. This ensures that the integrated modules produced in batches maintain a high degree of consistency in their physical assembly form.

[0027] Example 2: Figure 1-9 As shown, unlike Embodiment 1, the lead wire guiding structure 5 includes at least one lead wire groove 6 and at least one wire pressing rib 7 distributed along the wiring path. The lead wire groove 6 and the wire pressing rib 7 are respectively arranged on the bracket 4. The lead wire passes through the lead wire groove 6, and a portion of the lead wire is pressed and limited by the wire pressing rib 7.

[0028] In this embodiment, the lead wire guiding structure 5, through the combination of lead wire groove 6 and pressure rib 7, constructs a multi-dimensional physical constraint mechanism for the spatial orientation of the lead wire. Specifically, the lead wire is embedded in the lead wire groove 6, and the physical boundary of the lead wire groove 6 restricts the lateral displacement and random deformation of the lead wire in the horizontal plane, thereby precisely defining the basic wiring trajectory. On this basis, the pressure rib 7 presses against a specific section of the lead wire, sealing off the movement space of the lead wire in the height direction, effectively preventing the lead wire from slipping out of the groove or bouncing up when subjected to external forces. This wire-fixing structure, in which the groove and rib work together, significantly improves the position retention capability of the lead wire under severe vibration, drop impact, or long-term complex operating conditions, and blocks parasitic interference on the antenna radio frequency performance caused by internal cable deformation and displacement. In addition, this specific structure provides an intuitive and unique physical guide constraint for the actual assembly of the production line, requiring operators to lay the lead wires in line with the lead wire groove 6 and pass them through the limited gap of the pressure rib 7, fundamentally eliminating the problem of wire misalignment caused by differences in human assembly methods, and further ensuring the high consistency of the integrated module 1 in radio frequency communication indicators in mass production.

[0029] In one embodiment, the device further includes a housing 8, a cover 9, and a functional module 3. The circuit board 2 is fixedly installed inside the housing 8, the cover 9 is placed on the housing 8 and is detachably fastened to the housing 8, the functional module 3 is fixed on the circuit board 2 and electrically connected to the lead wire, and the cover 9 and the housing 8 together form a receiving cavity 10, in which the circuit board 2, the functional module 3, and the bracket 4 are all housed.

[0030] This structural design achieves complete enclosure and isolation of the core components (i.e., functional module 3) and internal wiring traces. The housing 10 constitutes a physical protective boundary, effectively preventing the intrusion of external dust, moisture, and conductive foreign objects, reducing the risk of short circuits and moisture aging of internal electronic components, thereby improving the reliability of the underlying hardware operating environment. In this implementation, the combination of the lead wire guiding structure 5 and the external housing protection further enhances its durability in harsh industrial environments.

[0031] The cover 9 and the base 8 are connected by a detachable snap-fit ​​method. While ensuring the overall sealing and structural strength of the components, this avoids additional fastener connection processes, improves the overall assembly efficiency of the manufacturing line, and allows maintenance personnel to quickly open the receiving cavity 10 during the long service life of the equipment. This enables non-destructive inspection, functional upgrades and component replacement of the internal functional modules 3 and lead wire nodes, giving the overall solution excellent engineering maintainability.

[0032] In this embodiment of the invention, the specific type of functional module 3 can be flexibly selected and replaced according to actual functional requirements. It can be any one or more combinations of communication modules (such as NB-IoT, 4G / 5G, LoRa, WiFi, Bluetooth, etc.), power modules (such as AC / DC conversion or battery management modules), processing and control modules (such as MCU or encryption modules), and sensing and measurement modules (such as high-precision sampling or sensor modules).

[0033] In one preferred embodiment, functional module 3 is specifically a customized radio frequency communication module (e.g., an ITRON private network communication module). Addressing the signal instability issues caused by the lack of a standard matching antenna and complex cross-regional communication environments in actual deployments of this type of module, the lead wire guiding structure 5 in this embodiment has been specifically physicalized based on the results of radio frequency integration testing. Specifically, through the cooperation of the lead wire groove 6 and the pressure rib 7, the direction, bending radius, and relative height between the lead wire 23 (in this embodiment, an antenna lead wire) and the circuit board 2 are precisely limited, thereby ensuring impedance consistency during signal transmission and effectively avoiding electromagnetic interference and signal attenuation caused by lead wire movement or disordered arrangement.

[0034] In one embodiment, a limiting structure for fixing the functional module 3 is also included. The limiting structure includes multiple limiting posts 11 and multiple limiting ribs 12. The multiple limiting posts 11 are disposed on the inner bottom surface of the box base 8 and extend upward. The upper part of the limiting posts 11 is used to support the bottom surface of the circuit board 2. The multiple limiting ribs 12 are disposed on the inner top surface of the box cover 9 and extend downward. When the box cover 9 is fastened to the box base 8, the bottom ends of the multiple limiting ribs 12 press against the top surface of the circuit board 2, thereby clamping and fixing the circuit board 2 in the vertical direction together with the multiple limiting posts 11.

[0035] In this embodiment, a vertical space locking mechanism for the functional module 3 and its circuit board 2 is constructed by configuring a limiting structure composed of limiting posts 11 and limiting ribs 12 between the cover 9 and the base 8. Specifically, multiple limiting posts 11 extending upward from the inner bottom surface of the base 8 provide multi-point rigid support for the bottom of the circuit board 2. When the cover 9 and the base 8 are fastened together, multiple limiting ribs 12 extending downward from the inner top surface of the cover 9 press down synchronously and finally abut against the top surface of the circuit board 2. This design significantly enhances the overall mechanical shock resistance of the functional module 3. When the device is subjected to severe external vibration or accidental drop, it can prevent the bottom electronic components of the internal circuit board from being desoldered and damaged due to inertial displacement, and ensure the routing stability of the aforementioned lead wire guiding structure 5.

[0036] Meanwhile, the aforementioned limiting method combines the fixing action of the internal module with the snapping action of the external shell, and uses the mechanical extrusion force generated by the shell closing to achieve rigid fixation. This eliminates the material requirement for additional screws and other independent fasteners inside, and while simplifying the final assembly process, it greatly improves the assembly efficiency of mass production and the long-term reliability of the product's physical structure.

[0037] In one embodiment, the limiting post 11 is stepped, including a lower limiting segment 13 and an upper limiting segment 14. The outer diameter of the lower limiting segment 13 is larger than the outer diameter of the upper limiting segment 14. The top of the lower limiting segment 13 forms a stepped surface 15 for reserving space for mounting the adapter circuit board. The circuit board 2 is supported on the upper limiting segment 14. The bottom ends of the multiple limiting ribs 12 respectively abut against multiple corresponding points on the top surface of the circuit board 2.

[0038] In this embodiment, the limiting column 11 adopts a stepped structure configuration. By setting the lower limiting segment 13 and the upper limiting segment 14 with different radial dimensions, a layered support system is constructed in the longitudinal space of a single column. This structural design effectively improves the comprehensive utilization rate of the internal space of the receiving cavity 10 and gives the component excellent hardware expandability and functional compatibility.

[0039] The lower limit segment 13 has a large outer diameter, and the stepped surface 15 formed at its top provides a dedicated reserved mounting reference for the adapter circuit board. When facing different application scenarios or communication protocol changes, this reserved space allows for the flexible addition of corresponding adapter circuit boards for hardware adaptation without changing the bottom box base 8 mold, thereby significantly reducing the product series development cycle and customized manufacturing cost.

[0040] Circuit board 2 is independently supported on the upper limit section 14, and multiple limiting ribs 12 extending downward from the cover 9 precisely abut against preset points on the top surface of circuit board 2. This point-to-point upper and lower pressing mechanism not only firmly locks circuit board 2 in the vertical dimension, preventing displacement of the equipment under vibration, but also creates sufficient longitudinal clearance space between circuit board 2 and the bottom surface of the housing 8. This design not only meets the requirement of interference-free arrangement of the adapter circuit board and bottom lead wires, but also optimizes the airflow cross-section of the internal heat-generating components, thereby improving the overall thermodynamic heat dissipation performance and electrical safety clearance while ensuring structural mechanical stability.

[0041] In one embodiment, the circuit board 2 is provided with a pin socket 16, and the bracket 4 is provided with a pin sleeve 17. The inner hole sidewall of the pin sleeve 17 has a draft angle that slopes inward from bottom to top, so that the inner hole of the pin sleeve 17 forms a contraction opening that is larger at the bottom and smaller at the top. The pin sleeve 17 is fitted onto the outside of the pin socket 16 from top to bottom, and the sidewall of the inner hole of the pin sleeve 17 is tightly fitted with the outer wall of the pin socket 16. The housing 8 is provided with a receiving portion 30 for the pin socket 16 to be inserted. The inner top surface of the housing cover 9 extends downward and is provided with a pressing member 18. When the housing cover 9 is fastened onto the housing 8, the pressing member 18 presses against the top of the pin sleeve 17.

[0042] In this embodiment, a locking mechanism for the bracket 4 is constructed by configuring a pin seat 16 and a pin sleeve 17 for insertion and mating between the housing 8 and the bracket 4, and by providing a pressing member 18 on the housing cover 9. Specifically, the inner hole of the pin sleeve 17 has a constricted opening configuration that is larger at the bottom and smaller at the top. The inner hole sidewall with the draft angle provides physical guidance in the initial stage of assembly, reducing the difficulty of alignment when the bracket 4 is inserted downwards. As the pin sleeve 17 is pushed from top to bottom, its inclined inner sidewall and the outer wall of the pin seat 16 generate a progressive wedge-shaped compression until the two are tightly fitted. This radial physical interference compression not only effectively eliminates the assembly gap between the bracket 4 and the housing 8 in the horizontal plane, but also utilizes the draft angle feature to accommodate the injection molding tolerances of the plastic parts.

[0043] Based on this, when the cover 9 is fastened, the pressing member 18 extending downward from the inner top surface of the cover 9 moves down synchronously and presses against the top of the pin sleeve 17, thereby sealing the axial clearance space of the bracket 4 in the vertical dimension. This structural system, which combines horizontal wedge-shaped insertion with vertical pressing, enables the bracket 4 to achieve excellent mechanical vibration resistance without the need for screws or other independent fasteners. This structural design significantly simplifies the process steps of the overall assembly line, while ensuring that the bracket 4 and its mounted lead wire guide structure 5 do not undergo relative displacement under long-term equipment vibration operation conditions, thus stabilizing the overall communication wiring system.

[0044] Example 3: Figures 1-9 As shown, unlike Embodiment 2, it also includes a sealing strip 20. The edge of the box base 8 is provided with an annular waterproof groove 19. The sealing strip 20 is fitted into the waterproof groove 19. The edge of the box cover 9 is provided with a pressing rib 31 that is adapted to the waterproof groove 19. When the box cover 9 is fastened to the box base 8, the pressing rib 31 extends into the waterproof groove 19 and presses against the sealing strip 20 to form a waterproof seal at the connection between the box base 8 and the box cover 9.

[0045] In this embodiment, the sealing strip 20 is independently assembled within the waterproof groove 19 on the edge of the box base 8, and is press-fitted by the crimping rib 31 protruding from the edge of the box cover 9. This structural design has significant advantages in improving sealing performance and optimizing assembly process. The crimping rib 31 extends into the waterproof groove 19, constructing a labyrinthine physical barrier, and converts the mechanical downward pressure generated when the box cover 9 is closed onto the box base 8 into a continuous compressive force on the sealing strip 20, forcing the sealing strip 20 to undergo elastic deformation and tightly adhere to the inner wall and bottom of the waterproof groove 19, thereby achieving a high-strength waterproof and dustproof seal. Under this pressure, the annular waterproof groove 19 provides a clear and closed physical limiting space for the sealing strip 20, effectively preventing the sealing strip 20 from shifting laterally to the inside or outside or from localized glue overflow, ensuring the integrity and consistency of the entire sealing shape.

[0046] The convex-concave fitting crimping rib 31 and waterproof groove 19 can play a self-guiding and positioning role when assembled, avoiding misalignment of the upper and lower shells, improving the efficiency and yield of production line assembly. This structure can also hard limit the downward stroke of the crimping rib 31, preventing the sealing strip 20 from permanent plastic deformation or fatigue damage due to excessive pressure, significantly extending the service life of the seal. The independently designed sealing strip 20 also provides great convenience for low-cost opening maintenance and non-destructive replacement of the equipment in the later stage.

[0047] In one embodiment, the bracket 4 is provided with a wire fixing area 21, the box base 8 is fixedly provided with a first external wiring interface 22, the lead wire includes a first lead wire 23, the functional module 3 is electrically connected to a first socket 24, the first socket 24 is fixed on the circuit board 2, and the multiple lead wire slots 6 include a first lead wire slot 32, a second lead wire slot 33 and a third lead wire slot 34. One end of the first lead wire 23 is inserted into the first socket 24, and the other end is connected to the first external wiring interface 22. The middle section of the first lead wire 23 is sequentially inserted into the first lead wire slot 32, the second lead wire slot 33, the bottom side of the wire clamping rib 7 and the third lead wire slot 34. After the first lead wire 23 passes through the wire fixing area 21, it bends into a loop shape on the side of the functional module 3 and continues to extend downward to the first external wiring interface 22.

[0048] In this embodiment, the functional module 3 is a radio frequency communication module. By configuring the first lead 23 with a routing trajectory consisting of multi-level lead grooves 6, wire clamps 7 and wire fixing areas 21, and combining it with a specific ring physical wiring topology, the underlying communication link is deeply optimized in both mechanical and electromagnetic dimensions.

[0049] Specifically, the middle section of the first lead wire 23 is sequentially clamped in the first lead wire groove 32, the second lead wire groove 33, the bottom side of the wire clamping rib 7, and the third lead wire groove 34. This multi-node, multi-station composite limiting mechanism eliminates the free movement margin of the cable in three-dimensional space, establishing a stable and unique wiring form. Based on this physical constraint, after the first lead wire 23 passes through the fixed wire area 21, it bends into a loop shape on the side of the functional module 3. This can effectively absorb and dissipate the external mechanical pulling force transmitted from the first external wiring interface 22, or the thermal expansion and contraction stress caused by temperature changes during long-term operation of the equipment. This stress isolation mechanism cuts off the path of destructive energy to the front-end first plug 24 from the physical source, avoiding mechanical fatigue or poor soldering at the bottom electrical connection nodes, and ensuring the long-term reliability of the overall connection architecture.

[0050] In one embodiment, a second lead 25 is also included. A second socket 26 is electrically connected to the functional module 3. A second external wiring interface 27 is fixedly provided on the housing 8. One end of the second lead 25 is inserted into the second socket 26. The second lead 25 is laid independently of the lead wire guiding structure 5 and is directly connected to the second external wiring interface 27.

[0051] In this embodiment, the lead system is further configured with a second lead 25 to meet the concurrent communication requirements of multi-antenna architecture or multi-band signals (such as main / diversity antenna composite design) of smart terminals. Accordingly, a second connector 26 and a second external connection interface 27 are respectively added to the circuit board 2 and the housing 8. In terms of wiring, one end of the second lead 25 is plugged into the second connector 26, which is significantly different from the restricted arrangement of the first lead 23. The second lead 25 is laid independently of the aforementioned lead guiding structure 5 and is directly connected to the second external connection interface 27 in a straight line or the shortest physical path.

[0052] The above design has the following advantages: On the one hand, by detaching the second lead 25 from the lead guide structure 5, the wiring spacing between the first lead 23 and the second lead 25 is forcibly increased in physical space, realizing spatial isolation of the dual-path RF transmission. This spatial isolation effectively weakens the electromagnetic coupling and RF crosstalk that are easily caused when adjacent high-frequency cables are routed in parallel, ensuring the isolation and signal purity when multiple signals are transmitted and received concurrently. On the other hand, for the transmission characteristics of secondary communication links or specific frequency bands, the direct connection method eliminates unnecessary bends and windings, forming the shortest physical transmission channel with the most continuous impedance, reducing the high-frequency insertion loss caused by the cable itself from the root, thereby optimizing the overall RF performance of the communication module.

[0053] Example 4: Figure 10 As shown, according to an embodiment of the present invention, a smart energy meter 28 is also provided, including a meter housing 29 and an integrated module 1, wherein the integrated module 1 is disposed in the meter housing 29.

[0054] In this embodiment, by embedding the integrated module 1 entirely within the casing 29 of the smart energy meter 28, an energy metering terminal system with a highly reliable system architecture is constructed. The integrated module 1, as a highly standardized independent unit, is assembled inside the casing 29. This nested structure effectively absorbs and buffers external mechanical vibrations and impact loads encountered by the equipment during long-distance logistics, on-site grid installation, and long-term service, preventing the core electronic components inside the device from becoming loose or suffering mechanical fatigue damage.

[0055] During this process, the lead wire guiding structure 5 implements forced physical restraint on the spatial orientation of the functional module leads, eliminating mechanical fatigue and stress concentration caused by environmental factors at the physical source. This effectively prevents loosening or poor soldering at the lead wire joints, greatly improving the structural strength of the internal connections of the entire device. When the functional module 3 is specifically selected as an RF communication module, this physical restraint further manifests as a strict solidification of the internal electromagnetic topology of the entire device. That is, by using a preset wiring path, it ensures that the sheathed leads and surrounding electronic components and metal supports maintain a constant relative physical position, thereby ensuring the long-term stability of antenna radiation parameters and RF impedance matching. This design fundamentally eliminates parasitic interference and signal attenuation caused by lead wire shaking, displacement, or messy arrangement, ensuring the accuracy and continuity of the underlying measurement data upload.

[0056] Furthermore, because the lead wire guiding structure 5 achieves modular pre-packaging of functional module 3 and its supporting wiring architecture, the overall production and assembly process of the smart energy meter 28 is significantly simplified. The assembly process only requires simple mechanical fixing and interface docking, which significantly reduces the human operation variables in the assembly process, thereby ensuring the consistency of structural strength and key performance indicators of mass-produced products, and effectively reducing the overall operation and maintenance costs throughout the equipment's life cycle.

[0057] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
