Description

Technical Field

[0001] This utility model relates to the field of combined application of aggregation device and multi-channel expansion device, specifically a low-voltage edge aggregation and multi-channel acquisition device. Background Technology

[0002] Low-voltage edge aggregation devices are a type of general-purpose master control device used as a communication medium between intelligent terminals and intelligent end devices in a distribution area, or as an intelligent terminal in a distribution area. Low-voltage edge aggregation devices can collect and manage intelligent end devices downwards, and transmit end device data upwards to intelligent terminals in the distribution area or platform master stations, solving the problem of interaction difficulties caused by long communication distances and mismatched communication functions, and helping to realize intelligent panoramic perception services in distribution areas.

[0003] The extended acquisition device is electrically connected to the low-voltage edge aggregation device. The extended acquisition device is a dedicated component, typically configured as a separate unit for each function, such as a CCO component, carrier listening component, temperature measurement component, or switch interface component. The extended acquisition device can collect relevant equipment data and send it to the low-voltage edge aggregation device.

[0004] In existing technologies, low-voltage edge aggregation devices and extended acquisition devices are typically designed as independent structures, achieving data transmission and other operations solely through electrical or communication connections. However, this approach is inconvenient for equipment management. Therefore, existing technologies employ methods such as bolted or adhesive connections for centralized management of the low-voltage edge aggregation devices and extended acquisition devices. However, relying solely on bolted or adhesive connections can lead to connection instability during long-term use, and because the uniformity of stress at the connection points cannot be guaranteed, localized damage is likely to occur, increasing the risk of equipment malfunction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing low-voltage edge devices and extended acquisition devices, which have poor overall connection, are not conducive to equipment management, and result in low connection stability between devices and easy local damage. This invention provides a low-voltage edge aggregation and multi-channel acquisition device. By setting up a low-voltage edge aggregation unit and several extended acquisition units, it integrates dedicated components for functional expansion. By splicing the low-voltage edge aggregation unit and the extended acquisition units, the pin header plug and pin header socket with electrical connection play a positioning connection role while ensuring communication connectivity. The positioning connection of the low-voltage edge aggregation unit and several extended acquisition units is achieved by using a plug-in form positioning connection.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] A low-voltage edge aggregation and multi-channel acquisition device includes a low-voltage edge aggregation unit and several extended acquisition units. Each extended acquisition unit has several pin headers on one side and extended pin header sockets on the opposite side, with the number and position corresponding to the pin headers. The low-voltage edge aggregation unit has aggregation pin header sockets on its side, with the number and position corresponding to the pin headers.

[0008] The pin header can be plugged into the collection pin header socket of the adjacent low-voltage edge collection unit or into the expansion pin header socket of the adjacent expansion collection unit: each pin header is inserted into a corresponding collection pin header socket or an expansion pin header socket.

[0009] Currently, when using low-voltage edge aggregation devices and extended acquisition devices for data acquisition and aggregation, the configuration of these devices can be quite chaotic because one low-voltage edge aggregation device needs to correspond to multiple extended acquisition devices. Existing technologies typically use external connections to centrally manage the low-voltage edge aggregation device and multiple extended acquisition devices, thus enhancing unified management capabilities. However, when adding extended acquisition devices, further planning and reorganization are required. This existing approach suffers from poor overall device integrity and low levels of unified management. Connecting multiple devices via cables leads to difficulties in cable management. Therefore, expanding the connections of extended acquisition devices to low-voltage edge aggregation devices in existing technologies often results in reduced device connection stability and data connection stability. This is because the connections between individual devices in existing technologies are fixed and independent, leading to poor overall integrity. Furthermore, using external wiring carries the risk of cable detachment, resulting in low device connection stability and data connection stability.

[0010] In this invention, by setting up a low-voltage edge aggregation unit and an extended acquisition unit, and using a direct plug-in connection method with a converged pin header socket and a pin header plug to connect the low-voltage edge aggregation and extended acquisition units, the stability of data transmission can be improved. The pin header plug and converged pin header socket serve as connection support points for the low-voltage edge aggregation and extended acquisition units when the device is connected as a whole. This achieves the goal of directly connecting the extended acquisition unit to the low-voltage edge aggregation unit, thereby improving the overall integrity of the device and enhancing data transmission stability through the plug-in connection method. Furthermore, since the low-voltage edge aggregation unit and the extended acquisition unit are connected in close contact, the connection stability of the device is also enhanced.

[0011] When more expansion acquisition units need to be connected, the number of expansion acquisition units can be increased by plugging the expansion header socket on the expansion acquisition unit with the header plug of the subsequently added expansion acquisition unit. Since it is a direct plug-in method, it also avoids the need for additional cables, thus effectively avoiding cable management difficulties.

[0012] Furthermore, a convergence sliding connection assembly is provided between the low-voltage edge convergence unit and the extended acquisition unit, and an extended sliding connection assembly is provided between the extended acquisition units;

[0013] The converging sliding connection assembly is detachably and fixedly connected to the low-voltage edge converging unit and the adjacent extended acquisition unit, and the extended sliding connection assembly is detachably and fixedly connected to two adjacent extended acquisition units.

[0014] The converging sliding connection assembly and the extended sliding connection assembly have the same structure.

[0015] In this invention, the gathering sliding connection assembly can release or lock the connection between the low-voltage edge gathering unit and the extended acquisition unit by sliding, and the extended sliding connection assembly can release or lock the connection between two adjacent extended acquisition units by sliding.

[0016] When the aggregation sliding connection assembly slides, it can detachably and securely connect the low-voltage edge aggregation unit and the extended acquisition unit; sliding in the opposite direction will disassemble the connection between the low-voltage edge aggregation unit and the extended acquisition unit.

[0017] The extended sliding connection assembly can fix and detach adjacent extended acquisition units in the same way.

[0018] Furthermore, the converging sliding connection assembly includes a first positioning lock hole, which is located on the side of the extended acquisition unit, and the side of the low-pressure edge converging unit is provided with a first buckle that can be inserted into the first positioning lock hole;

[0019] The top of the extended acquisition unit is provided with a top locking slider, which is embedded in the extended acquisition unit and can slide to engage with the first buckle.

[0020] In this utility model, the first positioning lock hole is on the side of the extended acquisition unit facing the low-pressure edge collection unit. The first buckle can be inserted into the first positioning lock hole. By sliding the top locking slider on the extended acquisition unit, the top locking slider can be effectively connected to the first buckle. The limiting of the connection results in a detachable and fixedly connected collection sliding connection assembly, thereby completing the detachable and fixed connection between the low-pressure edge collection unit and the extended acquisition unit.

[0021] Furthermore, the side of the extended acquisition unit is also provided with a second positioning lock hole;

[0022] The side of the low-pressure edge gathering unit is provided with a second buckle that can be inserted into the second positioning lock hole;

[0023] The bottom of the extended acquisition unit is provided with a bottom locking slider, which is embedded in the extended acquisition unit and can be slidably inserted into the second buckle;

[0024] The structure of the bottom locking slider is the same as that of the top locking slider.

[0025] This invention effectively balances the forces on the first positioning lock hole and the first buckle by setting a second positioning lock hole and a second buckle. The connection between the second positioning lock hole and the second buckle is achieved by a bottom locking slider, thereby strengthening the connection stability and firmness between the low-pressure edge gathering unit and the extended acquisition unit, and also effectively improving the connection between adjacent extended acquisition units.

[0026] Furthermore, the extended acquisition unit includes an extended unit housing, and the top of the extended unit housing is provided with a sliding groove;

[0027] The top locking slider includes a slider body, which is embedded in the slide groove and can slide along the slide groove. The slider body is provided with a plurality of positioning rods, which are used to insert the first buckle.

[0028] In this invention, the groove is used to accommodate the sliding of the slider body, and the position and number of the positioning rods correspond to the position and number of the first buckles. Each first buckle corresponds to at least one positioning rod, thereby realizing the connection between the low-voltage edge collection unit and the extended acquisition unit, or realizing the connection between adjacent extended acquisition units, by using the insertion between the positioning rod and the first buckle.

[0029] Furthermore, the slider body is provided with anti-slip ribs, which protrude from the outer shell of the extension unit.

[0030] The anti-slip ribs are used to prevent slipping, thereby facilitating the sliding of the slider body within the groove on the expansion unit housing.

[0031] Furthermore, the low-voltage edge collection unit is provided with a main back mount, and the extended acquisition unit is provided with an extended back mount. The mounting plane of the main back mount and the mounting plane of the extended back mount are the same plane.

[0032] In this invention, both the main back hanger and the extended back hanger are used to bear weight. The main back hanger can bear the weight of the low-voltage edge collection unit, and the extended back hanger is used to bear the weight of the extended acquisition unit, thereby enabling the device described in this invention to be suspended for a long time.

[0033] The mounting plane of the main back mount and the mounting plane of the extended back mount are the same plane, which can effectively integrate the spatial configuration of the low-voltage edge collection unit and several extended acquisition units, thereby effectively improving the adaptability when carrying and accommodating this utility model.

[0034] Since both the low-voltage edge aggregation unit and the extended acquisition unit in this invention have a large number of external connection cables, the low-voltage edge aggregation unit and the extended acquisition unit are suspended by the main back-mount and the extended back-mount, which facilitates wiring.

[0035] Furthermore, a main guide groove is provided on the low-pressure edge gathering unit, and a guide rail is provided in the main guide groove. The guide rail is located between the main back hanger and the main guide groove, and the guide rail is embedded in the main guide groove and abuts against the main back hanger.

[0036] An expansion guide groove is provided on the expansion acquisition unit, and the guide rail extends between the expansion guide groove and the expansion back mount. The guide rail is embedded in the expansion guide groove and abuts against the expansion back mount.

[0037] In this invention, the guide rail is used to support the weight of the entire device. The guide rail is clamped between the main guide groove and the main back hanger, and between the extension guide groove and the extension back hanger, thus utilizing the guide rail's limiting function to support the low-pressure edge gathering unit and the extension acquisition unit. The fixed position of the telescopic guide rail is determined by the environment, thereby improving the applicability of this invention.

[0038] In summary, this utility model has the following advantages compared with the prior art:

[0039] (1) By setting up a low-voltage edge aggregation unit and an extended acquisition unit, the low-voltage edge aggregation and extended acquisition units are connected by directly plugging in the aggregation pin socket and the pin plug.

[0040] (2) The pin header plug and the pin header socket are used as the connection support points for the low-voltage edge gathering and extended acquisition units when the device is connected as a whole, so as to achieve the purpose of directly connecting the extended acquisition units when connecting the extended acquisition units, based on the low-voltage edge gathering units.

[0041] (3) The first positioning lock hole is on the side of the extended acquisition unit facing the low-voltage edge collection unit. The first buckle can be inserted into the first positioning lock hole. By sliding the top locking slider on the extended acquisition unit, the top locking slider can be effectively connected to the first buckle. The detachable fixed connection of the collection sliding connection assembly is obtained by limiting the insertion, thereby completing the detachable fixed connection between the low-voltage edge collection unit and the extended acquisition unit.

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0054] Example:

[0055] like Figures 1-6 As shown, this embodiment relates to a low-voltage edge aggregation and multi-channel acquisition device, including a low-voltage edge aggregation unit 1 and a plurality of extended acquisition units 3. One side of the extended acquisition unit 3 is provided with a plurality of pin headers 5, and the opposite side is provided with an extended pin header socket corresponding to the number and position of the pin headers 5. The side of the low-voltage edge aggregation unit 1 is provided with a aggregation pin header socket 13 corresponding to the number and position of the pin headers 5.

[0056] The pin header 5 can be inserted into the collection pin header socket 13 of the adjacent low-voltage edge collection unit 1 or into the expansion pin header socket of the adjacent expansion collection unit 3: each pin header 5 is inserted into a collection pin header socket 13 or an expansion pin header socket.

[0057] In this embodiment Figures 1-5 The low-voltage edge collection unit 1 and the telescopic expansion collection unit 3 are in a split state. In actual use, the pin header 5 needs to be inserted into the collection pin header socket 13 or the expansion pin header socket to form a connected state.

[0058] In this embodiment, sufficient spacing is maintained between the pin headers to ensure electrical safety. The pin headers 5 can be symmetrically or asymmetrically distributed around the geometric center of the side of the extended acquisition unit 3.

[0059] In this embodiment, the specifications of the pin header 5 can be adjusted according to actual needs. If a symmetrical distribution is adopted, the insertion positions of the pin header 5 are symmetrical, and the external force is more balanced when it assists in bearing the weight of the extended acquisition unit 3. If an asymmetrical distribution is adopted, the insertion positions of the pin header 5 are flexible, thus enabling more adaptable insertion position arrangements.

[0060] For example, when using two pin headers 5, arranged symmetrically, one is located on the upper half of the side of the extended acquisition unit 3, and the other is located on the lower half of the side of the extended acquisition unit 3. In this case, the one located above is used for communication, and the one located below is used for power connection. Different specifications of pin headers 5 correspond to matching pin header sockets 13 or extended pin header sockets.

[0061] In practical applications, this embodiment effectively integrates the independent low-voltage edge aggregation device and the extended acquisition device by setting up the low-voltage edge aggregation unit 1 and the extended acquisition unit 3. The electrical connection between the low-voltage edge aggregation unit 1 and the extended acquisition unit 3 is completed by setting up the aggregation pin header socket 13 and the pin header plug 5. The extended acquisition unit 3 is provided with an extended pin header socket that can be further extended to connect other extended acquisition units 3. Thus, the number of extended acquisition units 3 can be effectively increased without affecting the basic configuration, so as to meet the purpose of different data acquisition.

[0062] This embodiment can effectively increase the types of data to be collected by increasing the number of expanded acquisition units 3, thereby having a strong scalability.

[0063] In this embodiment, the pin header 5 not only serves as an electrical connection but also provides a certain degree of support through the connection between the pin header 5 and the converging pin header socket 13. The connection between the pin header 5 and the extension pin header socket of the subsequent extended acquisition unit 3 also provides a certain degree of support. When the low-voltage edge converging unit 1 and the extended acquisition unit 3 have a foundation to support their own weight, the connection between the low-voltage edge converging unit 1 and the extended acquisition unit 3 can be effectively enhanced through the connection between the pin header 5 and the converging pin header socket 13. Furthermore, the connection between the pin header 5 and the extension pin header socket enhances the stability of the connection between two adjacent extended acquisition units 3.

[0064] like Figure 7 As shown in this embodiment, since the expansion pin header socket on the extended acquisition unit is sometimes idle, when the expansion pin header socket is idle, the expansion pin header socket can be protected by setting the pin header cover plate 15, thereby avoiding damage to the expansion pin header socket.

[0065] Furthermore, a convergence sliding connection assembly is provided between the low-pressure edge convergence unit 1 and the extended acquisition unit 3, and an extended sliding connection assembly 11 is provided between the extended acquisition units 3;

[0066] The converging sliding connection assembly is detachably and fixedly connected to the low-pressure edge converging unit 1 and the adjacent extended acquisition unit 3, and the extended sliding connection assembly 11 is detachably and fixedly connected to two adjacent extended acquisition units 3.

[0067] The converging sliding connection assembly and the extended sliding connection assembly 11 have the same structure.

[0068] In this embodiment, both the extended sliding connection assembly 11 and the converging sliding connection assembly can assist in positioning, thereby guiding the insertion of the pin header plug 5 and the converging pin header socket 13 or the pin header plug 5 and the extended pin header socket during the sliding connection process, preventing misalignment of the pin header plug 5 when it is inserted into the converging pin header socket 13 or the extended pin header socket, which could lead to damage to the components.

[0069] Furthermore, the gathering sliding connection assembly includes a first positioning lock hole 4, which is located on the side of the extended acquisition unit 3, and the side of the low-pressure edge gathering unit 1 is provided with a first buckle 10 that can be inserted into the first positioning lock hole 4.

[0070] The top of the extended acquisition unit 3 is provided with a top locking slider 2, which is embedded in the extended acquisition unit 3 and can slide to connect to the first buckle 10.

[0071] Furthermore, the side of the extended acquisition unit 3 is also provided with a second positioning lock hole 6;

[0072] The side of the low-pressure edge gathering unit 1 is provided with a second buckle 12 that can be inserted into the second positioning lock hole 6;

[0073] The bottom of the extended acquisition unit 3 is provided with a bottom locking slider 7, which is embedded in the extended acquisition unit 3 and can be slidably inserted into the second buckle 12;

[0074] The structure of the bottom locking slider 7 is the same as that of the top locking slider 2.

[0075] In this embodiment, the second positioning lock hole 6 and the first positioning lock hole 4 are symmetrically or asymmetrically distributed around the geometric center of the side of the extended acquisition unit 3. When a symmetrical distribution is adopted, the force on the first positioning lock hole 4 and the second positioning lock hole 6 can be more even. When an asymmetrical distribution is adopted, it is easier to design the opening position of the first positioning lock hole 4 and the second positioning lock hole 6, thereby effectively avoiding the distribution position of the electronic components inside the extended acquisition unit.

[0076] Furthermore, the extended acquisition unit 3 includes an extended unit housing 31, and the top of the extended unit housing 31 is provided with a groove 32;

[0077] The top locking slider 2 includes a slider body 22, which is embedded in the slide groove 32 and can slide along the slide groove 32. The slider body 22 is provided with a plurality of positioning rods 23, which are used to insert the first buckle 10.

[0078] Furthermore, the slider body 22 is provided with anti-slip ribs 21, which protrude from the expansion unit housing 31.

[0079] In this embodiment, the low-voltage edge gathering unit 1 and the extended acquisition unit 3 are connected by a gathering sliding connection assembly. The gathering sliding connection assembly increases the insertion positions of the low-voltage edge gathering unit 1 and the extended acquisition unit 3 by inserting a first retaining ring 10 into a first positioning locking hole 4. The top locking slider 2 slides, allowing it to insert into the first retaining ring 10 and limit its position, thus maintaining the first retaining ring 10 inserted into the first positioning locking hole 4, thereby achieving the connection between the low-voltage edge gathering unit 1 and the extended acquisition unit 3. Several first retaining rings 10 can be arranged side-by-side, further increasing the number of insertion positions and improving connection stability.

[0080] When the second buckle 12 and the second positioning lock hole 6 are introduced, the second positioning lock hole 6 and the first positioning lock hole 4 are symmetrically distributed around the geometric center of the side of the extended acquisition unit 3, which can effectively balance the force on the connection between the low-pressure edge collection unit 1 and the extended acquisition unit 3.

[0081] The connection between the second positioning lock hole 6 and the second buckle 12 is achieved by sliding the bottom locking slider 7, which is located at the bottom of the extended acquisition unit 3, thereby avoiding conflict with the sliding path of the top locking slider 2.

[0082] The bottom positioning slider has the same structure as the top positioning slider, so the bottom of the expansion unit housing 31 is also provided with a groove 32. The bottom locking slider 7 is the same as the top locking slider 2, both including a slider body 22. The slider body 22 is embedded in the groove 32 and can slide along the groove 32. The slider body 22 is provided with several positioning rods 23. At this time, the positioning rods 23 are used to insert the second buckle 12. Therefore, the bottom positioning slider also has the same slider body 22, and the second buckle 12 is limited in the second positioning lock hole 6 by inserting the positioning rods 23 on the slider body 22 into the second buckle 12, thereby achieving the purpose of enhancing the connection stability of the low-voltage edge collection unit 1 and the expansion acquisition unit 3.

[0083] In this embodiment, as Figure 8As shown, a position limiting block 34 can be provided inside the expansion unit housing 31, and the slider body 22 can be prevented from sliding freely by the mutual restriction between the limiting block 33 fixed on the slider body 22 and the position limiting block 34. This prevents the slider body 22 from shifting and causing the connection function of the converged sliding connection assembly or the extended sliding connection assembly to fail. The position limiting block 34 is in a thin sheet state, so it can push the slider body 22 to slide when an external force is directly applied to the slider body 22, and prevent the slider body 22 from sliding when no external force is applied.

[0084] Specifically, in this embodiment, a limiting block 33 is provided on the side of the slider body 22, and a stop limiting block 34 is provided inside the expansion unit housing 31. The stop limiting block 34 can restrict the sliding of the limiting block 33. When it is necessary to push the slider body 22, the anti-slip rib 21 is pressed and the slider body 22 is pushed. At this time, since the material itself can undergo elastic deformation to a certain extent, the limiting block 33 can bypass the stop limiting block 34, thereby causing the slider body 22 to slide. When the anti-slip rib 21 is released, the limiting block 33 can be restricted by the stop limiting block 34, thereby preventing the slider body 22 from sliding.

[0085] By using the limit block 33 and the position limit block 34, the sliding process of the top locking slider 2 and the bottom locking slider 7 can be set to two positions. Thus, when the positioning rod 23 is restricted or released, the state of the first buckle 10 or the second buckle 12 being restricted can be effectively reflected.

[0086] Furthermore, the low-voltage edge collection unit 1 is provided with a main back mount 8, and the extended acquisition unit 3 is provided with an extended back mount 9. The mounting plane of the main back mount 8 and the mounting plane of the extended back mount 9 are the same plane.

[0087] In this embodiment, both the main back hanger 8 and the extended back hanger 9 are used to bear weight. The main back hanger 8 can bear the weight of the low-voltage edge collection unit 1, and the extended back hanger 9 is used to bear the weight of the extended acquisition unit 3, so that the device described in this utility model can be suspended for a long time.

[0088] The mounting plane of the main back mount 8 and the mounting plane of the extended back mount 9 are the same plane, which can effectively integrate the spatial configuration of the low-voltage edge collection unit 1 and several extended collection units 3, thereby effectively improving the adaptability when carrying and accommodating this utility model.

[0089] Since both the low-voltage edge aggregation unit 1 and the extended acquisition unit 3 in this utility model have a large number of external connection lines, the low-voltage edge aggregation unit 1 and the extended acquisition unit 3 are suspended by the main back mount 8 and the extended back mount 9 to facilitate wiring.

[0090] When it is necessary to increase the number of extended acquisition units 3, a new connection is achieved by inserting the pin header 5 of the new extended acquisition unit 3 into the extended pin header socket of the extended acquisition unit 3 located at the end. Since the extended sliding connection assembly 11 and the converged sliding connection assembly have the same structure, the connection between two adjacent extended acquisition units 3 can be achieved through the extended sliding connection assembly 11 on the new extended acquisition unit 3.

[0091] Therefore, the extended sliding connection assembly 11 can effectively achieve a stable physical connection between two adjacent extended acquisition units 3, and the pin header plug 5 and the extended pin header socket can achieve a stable electrical connection between two adjacent extended acquisition units 3.

[0092] The low-pressure edge gathering unit is provided with a main guide groove, and a guide rail 14 is provided in the main guide groove. The guide rail 14 is located between the main back hanger 8 and the main guide groove. The guide rail 14 is embedded in the main guide groove and abuts against the main back hanger 8.

[0093] An expansion guide groove is provided on the expansion acquisition unit 3, and the guide rail 14 extends between the expansion guide groove and the expansion back hanger 9. The guide rail 14 is embedded in the expansion guide groove and abuts against the expansion back hanger 9.

[0094] In this embodiment, there are two types of load-bearing components for the overall load-bearing structure. One type is to directly hang the low-voltage edge collection unit 1 and the extended acquisition unit 3 using the main back hanger 8 and the extended back hanger 9. The other type is to use the main back hanger 8 and the main guide groove to clamp the guide rail 14, and the extended back hanger 9 and the extended guide groove to clamp the guide rail 14, so that the low-voltage edge collection unit 1 and the extended acquisition unit 3 are embedded on the guide rail 14, and the guide rail 14 forms the load-bearing structure.

[0095] When the conditions for hanging are met, this embodiment can be connected by using the main back mount 8 and the extended back mount 9.

[0096] When there is no suitable suspension condition, the embodiment can be supported by setting up guide rail 14. When necessary, the two methods can be combined to support the embodiment, for example, part of it can be hung and part of it can be supported by guide rail 14.

[0097] This embodiment employs multiple forms of carriers, enabling it to adapt to more complex application environments.

[0098] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
