Description

Technical Field

[0001] This utility model is a low-voltage distributor, belonging to the field of low-voltage distributors. Background Technology

[0002] In the field of low-current signal transmission, low-voltage distributors are key devices for splitting and switching audio, video, and network signals. They are widely used in home audio-visual systems, office conference rooms, security monitoring rooms, industrial control centers, and other scenarios. With the popularization of digital devices, signal types are becoming increasingly diversified (such as HDMI, VGA, RJ45, USB, etc.), and transmission rates are constantly improving (such as 4K HDMI signal bandwidth reaching 18Gbps). Traditional low-voltage distributors are gradually revealing their technical shortcomings in adapting to complex scenarios.

[0003] Traditional low-voltage splitters often use fixed interface designs, meaning that specific types of interfaces such as HDMI and VGA are pre-installed at the factory, making it impossible to flexibly change them according to actual needs. For example, if a conference room is initially equipped with a VGA interface splitter, and later upgrades to HDMI equipment, the entire splitter needs to be replaced, resulting in idle and wasteful equipment. At the same time, the fixed number of interfaces is difficult to adapt to multi-terminal scenarios. For example, when a security monitoring system needs to connect to 8 camera signals simultaneously, a traditional 4-port splitter needs to be cascaded for expansion, which can easily cause signal attenuation. Therefore, it is necessary to design a low-voltage splitter. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-voltage distributor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage distributor, comprising: Electrical mounting rail with a mounting base on top; A protective cover is installed on top of the mounting base, and a plug-in socket is provided on the top of the protective cover; The moisture-absorbing box is plugged into the connector. There are two ventilation filter components, which are symmetrically inserted into both sides of the protective cover. A cooling fan is located on one side inside the protective cover; Multiple terminals are evenly spaced, and all terminals are located at the same end of the protective cover. The module sockets are provided at equal intervals, and all module sockets are located at the end of the protective cover away from the terminal block. Each module socket is equipped with an indicator light. The interface unit module is plugged into the module socket. Dust plugs are inserted into the module sockets where the interface unit module is not plugged in.

[0006] Furthermore, the protective cover and the mounting base are first snapped together and then fixed with bolts, and a sealing strip is provided at the joint between the protective cover and the mounting base.

[0007] Furthermore, the ventilation and filtration assembly includes a top plate, a pull ring, an outer frame, a filter screen, and a plug-in rib. The bottom of the top plate is integrally provided with an outer frame, and a pull ring is provided at the center of the top of the top plate. Plug-in ribs are installed at both ends of the outer frame, and a filter screen is provided inside the outer frame. Plug-in limiting plates are symmetrically provided at both ends of both sides of the protective cover, and the cross-section of the plug-in limiting plates is designed in an "L" shape. The plug-in ribs are adapted to the plug-in limiting plates. A slot is opened at the top of the plug-in limiting plates, and a locking block adapted to the slot is provided at both ends of the bottom of the top plate.

[0008] Furthermore, the shape of the moisture-absorbing box matches the plug-in socket, and the bottom of the moisture-absorbing box extends into the protective cover. The moisture-absorbing box is filled with moisture-absorbing particles. The outer surface of the moisture-absorbing box has multiple through holes in a matrix shape. The top of the moisture-absorbing box is slidably connected to a cover plate. The length and width of the cover plate are both greater than the length and width of the plug-in socket, and a lifting ring is provided at the center of the top of the cover plate.

[0009] Furthermore, the mounting base includes a base plate, a fixed plate, bolt grooves, a mounting frame, a movable plate, a movable hook, a compression spring, and a fixed hook. The top of the base plate is snapped into the protective cover, and fixed plates are installed on both sides of the bottom of the base plate. Bolt grooves are provided on both sides of both ends of the fixed plate, and a fixed hook is integrally connected to one end of the bottom of the fixed plate. A mounting frame is provided at the other end of the bottom of the fixed plate, and a movable plate is connected to the mounting frame through a compression spring. A movable hook is integrally provided at the end of the movable plate near the fixed hook.

[0010] Furthermore, the shape of the movable plate matches the mounting frame, and the movable hook and the fixed hook are symmetrically arranged. The movable hook and the fixed hook are respectively locked on the flanges at both ends of the top of the electrical installation guide rail. Slide grooves are opened on both sides inside the mounting frame, and sliders are slidably connected in the slide grooves. The sliders are fixedly connected to the side of the movable plate.

[0011] Furthermore, multiple interface unit modules are provided, which can be flexibly increased or decreased according to the actual signal type and quantity.

The two sides of the module socket are provided with buckle grooves that are adapted to the buckles. The head of the buckle is designed as a barb structure with a guide bevel.

[0012] The beneficial effects of this utility model are: 1. Adopting a modular interface unit design, the interface unit modules can be flexibly replaced according to actual needs, and the replacement process does not require tools. It can be completed by quick snap-fitting of the buckle and slot. When the scenario needs to be upgraded, only the corresponding interface module needs to be replaced, without replacing the entire distributor. This completely solves the problem of equipment idle waste caused by traditional fixed interface design and significantly reduces upgrade costs.

[0013] 2. The spring-loaded movable hook design of the mounting base enables quick mounting of the guide rail, which is more efficient than traditional bolt fixing. The ventilation filter assembly, moisture absorption box and other vulnerable parts adopt a plug-in structure, which does not require disassembling the whole machine for maintenance. It can be operated by a single person. During operation, the cooling fan drives the air flow inside the protective cover. The external cold air enters after being filtered by the filter screen of the ventilation filter assembly, and the hot air is discharged from the ventilation assembly on the other side, forming convection cooling. The filter screen is fixed by the cooperation of the plug-in ridge and the plug-in limit plate, and can be quickly disassembled for cleaning. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 6 This utility model provides a technical solution: a low-voltage distributor, including an electrical mounting rail 6, a mounting base 5 on the electrical mounting rail 6, a protective cover 1 on top of the mounting base 5, and a plug-in socket 101 on the top of the protective cover 1. A moisture-absorbing box 3 is plugged into the plug-in socket 101. Two ventilation filter components 2 are provided, and the two ventilation filter components 2 are symmetrically plugged into both sides of the protective cover 1. A cooling fan 7 is located inside the protective cover 1 on one side. Multiple terminals 4 are evenly spaced and located at the same end of the protective cover 1. Multiple module sockets 10 are evenly spaced and located at the end of the protective cover 1 away from the terminals 4. Each module socket 10 is provided with a [missing information - likely a typo]. Indicator light 11, interface unit module 12, and module socket 10 are plugged in. Dust plugs 9 are inserted into the module sockets 10 where interface unit module 12 is not plugged in. The combination design of electrical installation rail 6 and mounting base 5 is compatible with the industry-standard rail installation and can be quickly fixed in scenarios such as low-voltage cabinets. Compared with the traditional bolt fixing method, the installation efficiency is higher. The plug-in design of top plug 101 and moisture absorption box 3 can specifically absorb moisture inside the protective cover 1, which is especially suitable for humid environments such as the plum rain season in the south and the condensation environment of the computer room, reducing the risk of short circuit due to moisture. The symmetrical ventilation and filter components 2 on both sides and the internal heat dissipation fan 7 form a directional airflow channel, which can not only dissipate heat efficiently, but also filter dust and impurities, extending the service life of the equipment.

[0017] Please see Figure 1 The protective cover 1 and the mounting base 5 are first snapped together and then fixed with bolts. A sealing strip is provided at the joint between the protective cover 1 and the mounting base 5. The double fixing method of snapping and bolts improves the overall connection strength between the protective cover 1 and the mounting base 5. The sealing strip can fill the gaps and form a complete waterproof and dustproof barrier, effectively preventing dust particles and splash water from entering the interior of the protective cover 1.

[0018] Please see Figure 1 , Figure 2 and Figure 3 The ventilation and filtration assembly 2 includes a top plate 201, a pull ring 202, an outer frame 203, a filter screen 204, and a connecting rib 205. The outer frame 203 is integrally formed at the bottom of the top plate 201, and a pull ring 202 is located at the center of the top of the top plate 201. Connecting ribs 205 are installed at both ends of the outer frame 203, and a filter screen 204 is installed inside the outer frame 203. Connecting limiting plates 8 are symmetrically arranged at both ends of both sides of the protective cover 1, and the cross-section of the connecting limiting plates 8 is "L"-shaped. The connecting ribs 205 are adapted to the connecting limiting plates 8, and a slot 801 is provided at the top of the connecting limiting plates 8. Both ends of the bottom of the top plate 201 are equipped with locking blocks 206 that are compatible with the slots 801. The ventilation filter component 2 forms a precise guiding fit with the plug-in limiting plates 8 on both sides of the protective cover 1 through the plug-in ridge 205. The "L"-shaped plug-in limiting plate 8 provides lateral support for the outer frame 203 and prevents installation deviation through longitudinal limiting, ensuring that the installation position is consistent each time. The locking blocks 206 at the bottom of the top plate 201 and the slots 801 at the top of the plug-in limiting plate 8 form a quick lock. With the pull ring 202 at the top, a single person can quickly complete the plugging and unplugging replacement of the component, which is more efficient than the traditional screw fixing structure.

[0019] Please see Figure 2 and Figure 5 The shape of the moisture-absorbing box 3 matches the plug-in socket 101, and the bottom of the moisture-absorbing box 3 extends into the protective cover 1. The moisture-absorbing box 3 is filled with moisture-absorbing particles. The outer surface of the moisture-absorbing box 3 has multiple through holes 301 in a matrix pattern. The top of the moisture-absorbing box 3 is slidably connected to a cover plate 303. The length and width of the cover plate 303 are larger than the length and width of the plug-in socket 101. A lifting ring 302 is provided at the center of the top of the cover plate 303. The sliding connection design between the cover plate 303 and the moisture-absorbing box 3 allows the entire box to be filled without disassembling when replacing the moisture-absorbing particles. Simply slide open the cover plate 303 to quickly fill the box. The lifting ring 302 at the top makes it easy to grip and apply force. Combined with the plug-in structure of the plug-in socket 101, a single person can easily insert and remove the entire moisture-absorbing box 3.

[0020] Please see Figure 1 and Figure 6The mounting base 5 includes a base plate 501, a fixing plate 502, a bolt groove 503, a mounting frame 504, a movable plate 505, a movable hook 5051, a compression spring 506, and a fixing hook 507. The top of the base plate 501 is snapped into the protective cover 1, and fixing plates 502 are installed on both sides of the bottom of the base plate 501. Bolt grooves 503 are provided on both sides of both ends of the fixing plate 502, and a fixing hook 507 is integrally connected to one end of the bottom of the fixing plate 502. The other end of the bottom of the fixing plate 502 is provided with a mounting hook 507. The frame 504 is connected to a movable plate 505 via a compression spring 506. The movable plate 505 has a movable hook 5051 integrally provided at one end near the fixed hook 507. The mounting base 5 achieves double fixation through the cooperation of the fixed hook 507 and the movable hook 5051: the fixed hook 507 first engages with one side flange of the electrical mounting guide rail 6, and the movable plate 505 pushes the movable hook 5051 to clamp the other side flange of the guide rail under the elastic force of the compression spring 506, thus completing the fixation without tools.

[0021] Please see Figure 6 The shape of the movable plate 505 matches the mounting frame 504, and the movable hook 5051 and the fixed hook 507 are symmetrically arranged. The movable hook 5051 and the fixed hook 507 are respectively locked on the flanges at both ends of the top of the electrical installation guide rail 6. The mounting frame 5044 has a sliding groove 5041 on both sides inside, and a slider 5052 is slidably connected in the sliding groove 5041. The slider 5052 is fixedly connected to the side of the movable plate 505. The matching design ensures that the movable plate 505 is always precisely constrained by the mounting frame 504 during the extension and retraction process, avoiding lateral displacement. The symmetrical arrangement of the movable hook 5051 and the fixed hook 507 ensures that the flanges at both ends of the top of the electrical installation guide rail 6 are evenly stressed. The sliding groove 5041 limits the longitudinal movement of the slider 5052, preventing the movable plate 505 from detaching from the mounting frame 504 and ensuring structural integrity.

[0022] Please see Figure 2 and Figure 4Multiple interface unit modules 12 are provided, which can be flexibly increased or decreased according to the actual signal type and quantity. Each interface unit module 12 includes a socket 1201, a power connector 1202, and a latch 1203. The shape of the socket 1201 matches the internal shape of the module socket 10, and the power connector 1202 is integrally connected to one end of the socket 1201 near the center of the protective cover 1. Hooks 1203 are symmetrically arranged at both ends of the socket 1201, and latching slots 1001 adapted to the latches 1203 are provided on both sides of the module socket 10. The head of the latch 1203 is designed as a barbed structure with a guide bevel. The interface unit module 12 can be adjusted according to the actual signal type, such as HDMI, VGA, etc. The number of RJ45 modules can be flexibly increased or decreased without being limited by fixed interface configurations. For example, in a conference room setting, three HDMI modules and two audio modules can be configured as needed. When switching to a security monitoring setting, multiple RJ45 network modules can be quickly replaced, completely solving the limitation of traditional splitters that are "one device for one use" and greatly improving the device's adaptability to different scenarios. The integrated power connector 1202 and socket 1201 form a continuous conductive path. The clips 1203 at both ends of the socket 1201 are precisely matched with the slots 1001 of the module socket 10. The barbed structure with a guide bevel eliminates the need for deliberate alignment during the insertion process. The beveled guide clips 1203 automatically retract and snap into the slots 1001.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
