Description

Technical Field

[0001] This utility model relates to switch equipment, and more particularly to a power blanking baffle device for a switch and a switch equipment having the same. Background Technology

[0002] In modern data centers and enterprise networks, rack-mounted equipment such as network switches and servers play a crucial role. To ensure business continuity and equipment operational stability, these devices are typically designed to support redundant power systems, meaning the chassis has at least two power supply slots to enable hot backup or load sharing of power modules.

[0003] In actual deployments, users may initially configure only one power module for the device based on initial business needs, cost budget, or power consumption considerations. In this case, to maintain the integrity of the internal cooling airflow, prevent dust or foreign objects from entering the device, and ensure good electromagnetic shielding, unused power slots typically need to be sealed with a power supply blanking plate.

[0004] In related technologies, the power supply blank bracket is typically fixed to the power supply slot in the chassis with screws. When users need to upgrade the equipment or install a second power module in the future, this blank bracket must be removed first. Maintenance personnel need to use a Phillips screwdriver to completely unscrew the screws fixing the bracket. Afterwards, because the bracket fits tightly with the slot, it is often difficult to remove it by hand. A flathead screwdriver or other flat tools are needed to carefully pry it open from the gaps along the edge of the bracket before it can be finally removed. This disassembly method is cumbersome and requires the use of two different tools, which brings inconvenience to on-site installation and maintenance work and reduces the efficiency of deployment and upgrades. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] The following describes in detail, with reference to the accompanying drawings, a power supply blanking baffle device for a switch and a switch device having the same.

[0060] Reference Figures 1 to 5 As shown, the power supply blanking baffle device for a switch provided according to an embodiment of the present invention is mainly used in scenarios where only some power modules are configured at the factory, to close reserved slots where no power supply is installed. The power supply blanking baffle device 20 includes a housing 10, a baffle 20, and a handle 30.

[0061] Specifically, one side of the housing 10 has a power supply recess P10. That is, one or more openings for installing power modules are provided on one side panel (e.g., the rear panel) of the housing 10. When no power supply is installed in a certain opening, a power supply recess P10 is formed. The power supply recess P10 has a specific internal contour and size to facilitate the installation of power modules when needed.

[0062] The baffle 20 includes a back plate 201, two first side plates 202 and two second side plates 203. The two first side plates 202 are arranged opposite to each other in the length direction of the back plate 201 and are perpendicular to the back plate 201. The two second side plates 203 are arranged opposite to each other in the width direction of the back plate 201 and are perpendicular to the back plate 201.

[0063] For example, the baffle 20 can be integrally stamped from a metal material (such as galvanized steel sheet or spring steel) with a certain strength and elasticity. The main body of the baffle 20 is a flat back plate 201, the size of which is slightly larger than or equal to the opening of the power supply cavity P10, so that it can completely cover the opening after installation, providing good sealing and dustproofing. Two first side plates 202 and two second side plates 203 extend vertically from the four edges of the back plate 201, respectively. The two first side plates 202 are arranged opposite each other in the length direction (e.g., left-right direction) of the back plate 201, and the two second side plates 203 are arranged opposite each other in the width direction (e.g., up-down direction) of the back plate 201. The four side plates together form a shallow box-shaped structure, the outer contour of which is designed to be tightly inserted into the power supply cavity P10.

[0064] The first side plate 202 and the second side plate 203 are adapted to be inserted into the power supply blanking cavity P10, and the first side plate 202 and / or the second side plate 203 are snapped together with the inner wall of the power supply blanking cavity P10 so as to close the power supply blanking cavity P10 by means of the baffle 20.

[0065] In other words, a snap-fit ​​structure is provided between the first side plate 202 and / or the second side plate 203 and the inner wall of the power supply blanking cavity P10, which enables quick installation between the baffle 20 and the housing 10. For example, when the baffle 20 is pushed into the power supply blanking cavity P10, the first side plate 202 and the second side plate 203 respectively contact the four inner walls of the power supply blanking cavity P10. Furthermore, as the pushing force is applied, when the push plate is pushed into place, the snap-fit ​​structure between the first side plate 202 and / or the second side plate 203 and the inner wall of the power supply blanking cavity P10 engages, thereby securing the baffle 20 to the housing 10.

[0066] Preferably, the first side plate 202 and / or the second side plate 203 are provided with a latching part 204, and the inner wall of the power supply blanking cavity P10 is provided with a groove H101 that engages with the latching part 204. The latching part 204 can be designed as a protruding spring or elastic arm structure, which has a guide slope S2a and a backing surface S2b for positioning. When the baffle 20 is pushed into the power supply blanking cavity P10, the guide slope S2a first contacts the inner wall of the blanking cavity. With the action of the pushing force, the elastic latch will elastically deform along the slope direction and contract inward, so that the baffle 20 can smoothly enter the cavity. When the baffle 20 is pushed to the predetermined position, the latching part 204 enters the groove H101 and quickly returns to its original shape due to its own elasticity, thus achieving engagement. This latching connection method utilizes the elastic deformation and recovery characteristics of the material itself to achieve a fast and reliable self-locking function.

[0067] The handle 30 is fixed to the back panel 201 for the user to grip and operate. The handle 30 can take various forms, such as a ring-shaped pull or a foldable, flip-up handle, as long as it provides a stable and easy-to-grip point for the user. When this blank cover 20 needs to be removed to add a power module to the switch, maintenance personnel do not need to use any tools; they simply grasp or hold the handle 30 and apply an outward pulling force. This pulling force is sufficient to overcome the locking force of the latching structure, forcing the first side panel 202 and the second side panel 203 to disengage from the power supply blank cavity P10, thus allowing the entire cover 20 device to be smoothly pulled out.

[0068] According to the power supply blanking plate device for a switch provided in this embodiment of the present invention, a structure is provided on the side plate of the blanking plate 20 for snap-fit ​​connection with the inner wall of the power supply blanking cavity P10, and a handle 30 for easy operation is added. This allows the installation and removal of the blanking plate 20 to be done without any tools. During installation, maintenance personnel only need to push the blanking plate 20 into the slot for automatic locking. When it is necessary to remove it to add power, simply grasp the handle 30 and pull it outwards to easily release the snap and remove the blanking plate 20. Therefore, this device eliminates the tedious steps of using a Phillips screwdriver to loosen screws and a flathead screwdriver to pry open the blanking plate 20, greatly simplifying the operation process and improving the efficiency of on-site installation, maintenance, and upgrades.

[0069] Reference Figures 2 to 3 As shown, in one embodiment of this utility model, the back plate 201 is provided with a through hole H201, and the handle 30 includes an outer stop 301, an elastic expansion part 302, and a pull handle part 303. Preferably, the handle 30 can be made of a plastic material with good toughness and elastic recovery ability (such as polycarbonate PC, ABS resin), and integrally molded by injection molding process.

[0070] The outer stop 301 abuts against the outer side of the back plate 201. The outer stop 301 can be a block or sheet structure with an area larger than the through hole H201 of the back plate 201. After assembly, the outer stop 301 fits tightly against the outer surface of the back plate 201, ensuring the accuracy and stability of the handle 30's installation position.

[0071] The elastic expansion portion 302 is connected to the outer stop portion 301 and passes through the through hole H201 before stopping on the inner side of the back plate 201. In its natural state, the elastic expansion portion 302 expands outwards, with its maximum outer contour size larger than the diameter of the through hole H201. When the handle 30 is installed onto the back plate 201, as the elastic expansion portion 302 is pushed towards the through hole H201, its leading edge guides the elastic expansion portion 302 to contract inwards under the pressure of the edge of the through hole H201, temporarily making its outer contour size smaller than the hole diameter, thus allowing it to pass through smoothly. Once the elastic expansion portion 302 has completely passed through the through hole H201, it instantly returns to its expanded state due to the elasticity of its material. At this point, the elastic expansion portion 302 will be firmly locked onto the inner surface of the back plate 201.

[0072] The handle 303 is located on the outside of the back panel and connected to the outer stop 301, for the user to grip and operate. The handle 303 is the part that the user can directly contact and apply force to, and its specific shape can be designed according to ergonomics to make it easy to grip, ensuring that the user can hold it comfortably and securely.

[0073] During assembly, the operator only needs to align the elastic expansion part 302 of the handle 30 with the through hole H201 on the back plate 201 and apply a simple pressing action to press the elastic expansion part 302 into the through hole H201 and stop it on the inside of the back plate 201, without any auxiliary tools. This quick-release structure makes the assembly of the handle 30 and the baffle 20 simpler and more convenient. When the user needs to operate the entire power blank baffle 20 device, the entire baffle 20 device can be pulled out from the power blank cavity P10 by applying the pulling force to the handle part 303, realizing its installation or removal in the switch housing 10.

[0074] In this embodiment, the structure of the handle 30 described above is adopted, and the elastic expansion part 302 and the through hole H201 of the back plate 201 are used to realize a press-type buckle installation method, which greatly simplifies the production and assembly process of the baffle 20 device, eliminates traditional fasteners such as screws and rivets and corresponding installation tools, and effectively reduces manufacturing costs.

[0075] Reference Figures 2 to 4 As shown, in one embodiment of this utility model, the elastic expansion portion 302 includes a central portion 3021 and two elastic arms 3022. The first end of the central portion 3021 is connected to the outer stop portion 301, and the second end of the central portion 3021 protrudes inward toward the outer stop portion 301. The central portion 3021 is a columnar structure, with its first end integrally connected to the outer stop portion 301 of the handle 30, and its second end extending inward (i.e., toward the back plate 201).

[0076] Two spring arms 3022 are symmetrically arranged on both sides of the central part 3021. One end of each spring arm 3022 is connected to the second end of the central part 3021, and the two spring arms 3022 form a V-shaped structure. The narrow end of the V-shaped structure faces the back plate 201 to pass through the through hole H201, and the other end of the two spring arms 3022 is stopped on the inner side of the back plate 201.

[0077] In other words, the opening of the V-shaped structure faces the outer stop 301, while its narrow end, the tip where the two spring arms 3022 meet the central part 3021, faces the back plate 201. Thus, during installation, the narrow end of the V-shaped structure acts as a guide, allowing the operator to quickly and accurately align and insert it into the through hole H201 on the back plate 201. Once the two spring arms 3022 have completely passed through the thickness of the back plate 201, the constraint force from the inner wall of the through hole H201 instantly disappears, and the two spring arms 3022 quickly spring back to their initial V-shaped expansion state due to the elastic recovery ability of their material. The other end of each spring arm 3022, the free end away from the central part 3021, acts as a stop structure, abutting against the inner surface of the back plate 201, thereby completing the fixation of the entire handle 30.

[0078] In this embodiment, the elastic expansion portion 302 employs a structure of a central portion 3021 and a spring arm portion 3022, which simplifies the installation operation, allowing the operator to quickly complete the assembly without precise alignment. The two symmetrical spring arm portions 3022 ensure the stability and reliability of the connection after installation.

[0079] Reference Figures 2 to 4 As shown, in one embodiment of this utility model, the second end of the central portion 3021 has a trapezoidal stop block 3023. The small end of the trapezoidal stop block 3023 faces the back plate 201 and passes through the through hole H201 before stopping inside the back plate 201. Preferably, the through hole H201 is a cross-shaped hole, and the plane where the trapezoidal stop block 3023 is located is perpendicular to the plane where the two spring arms 3022 are located, so as to fit into the cross-shaped hole. In this way, during installation, the two V-shaped spring arms 3022 can be smoothly inserted into one of the slots (e.g., a horizontal slot) of the cross-shaped hole, while the trapezoidal stop block 3023 is simultaneously inserted into the other slot (e.g., a vertical slot) perpendicular to it.

[0080] In the specific assembly operation, the operator holds the handle 30 and aligns its elastic expansion part 302 with the cross-shaped hole on the back plate 201. Since the planes of the elastic arm part 3022 and the trapezoidal stop block 3023 are perpendicular to each other, when the operator applies pressure, the small end of the trapezoidal stop block 3023 and the narrow end of the V-shaped structure enter their respective slots, playing a precise guiding role. As the pressure continues, the V-shaped elastic arm part 3022 is squeezed inward by the side wall of the slot and shrinks its outer contour size; at the same time, the trapezoidal stop block 3023 also slides smoothly through its corresponding slot. When the entire elastic expansion part 302 has completely passed through the thickness of the back plate 201, the constraint force applied to the elastic arm part 3022 disappears instantly, allowing it to quickly return to the open state due to the elasticity of the material, and its end is firmly stuck inside the back plate 201. At the same time, the trapezoidal stop block 3023 has also passed through completely, and its larger bottom surface forms a stable stop surface, which also closely abuts against the inner surface of the back plate 201.

[0081] Through the above structure, the handle 30 is ultimately fixed to the back plate 201 by two mutually perpendicular structures. This bidirectional, orthogonal locking method greatly enhances the stability of the connection and improves the reliability of operation.

[0082] Reference Figures 3 to 4 As shown, in one embodiment of the present invention, the outer baffle 301 is plate-shaped, and the inner side of the outer baffle 301 also has a conical disc 304. The conical disc 304 surrounds the first end of the central part 3021, and the large end of the conical disc 304 stops on the outside of the back plate 201 and is in a compressed state.

[0083] In this embodiment, the conical disc portion 304 continuously generates an elastic force along the axial direction of the central portion 3021. This elastic force forms a bidirectional axial preload force, which tightly pulls the stop end face of the elastic expansion portion 302 against the inner side of the back plate 201, while simultaneously pressing the large end of the conical disc portion 304 tightly against the outer side of the back plate 201. This ensures a gapless, tight connection between the handle 30 and the back plate 201, preventing the handle 30 from shaking and improving the feel and reliability of operation. Simultaneously, the tightly compressed conical disc portion 304 also seals the through hole H201, better preventing dust and other fine particles from entering through the gaps where the handle 30 is installed.

[0084] Reference Figure 4 As shown, in one embodiment of the present invention, the outer stop portion 301 has inwardly protruding stop portions at both ends, and the stop portions stop on the outer side of the back plate 201.

[0085] By providing inwardly protruding flanges at both ends of the outer stop 301, two support positions are formed at both ends of the outer stop 301. This wide base support method improves the stability of the handle 30, effectively prevents shaking during use, and enhances operational stability.

[0086] Reference Figures 1 to 3 As shown, in one embodiment of the present invention, the back plate 201 has ear flaps 2011 on both sides along its length. When the first side plate 202 and the second side plate 203 are inserted into the power supply blanking cavity P10, the two ear flaps 2011 stop on the outside of the housing 10.

[0087] In this embodiment, by providing lugs 2011 on both sides of the back plate 201, the lugs 2011 provide physical limits, ensuring that the baffle 20 can be installed to the predetermined depth. This guarantees that the internal snap-fit ​​structure can reliably engage, greatly improving the accuracy of installation and the firmness of the connection. Furthermore, installation is simple; just push it in, improving the convenience of the installation operation.

[0088] Reference Figure 5 As shown in the figure, this utility model embodiment also provides a switch device having a power blanking baffle device as described in the above embodiment.

[0089] According to the switch device provided in this embodiment of the utility model, a structure is provided on the side plate of the baffle 20 for snap-fit ​​connection with the inner wall of the power supply cavity P10, and a handle 30 for easy operation is added. This allows the installation and removal of the baffle 20 to be done without any tools. During installation, maintenance personnel only need to push the baffle 20 into the slot for automatic locking and fixation. When it is necessary to remove it to add power, simply hold the handle 30 and pull it outward to easily release the snap and remove the baffle 20. Therefore, this device eliminates the tedious steps of using a Phillips screwdriver to loosen screws and a flathead screwdriver to pry open the baffle 20, greatly simplifying the operation process and improving the efficiency of on-site installation, maintenance and upgrades.
