Description

Technical Field

[0001] The utility model relates to the field of server equipment, in particular to a server box ear component and a server. Background Art

[0002] Server enclosure ears are raised structures designed specifically for connecting to server cabinets or other equipment, ensuring stable server installation. They typically feature power switches, ports, and other operational features, facilitating daily management and maintenance.

[0003] Based on this, the server box ear usually has an independent PCB board (box ear plate) to carry the above functions. Therefore, the box ear plate also has the need for grounding and electromagnetic shielding. The current structure of the box ear plate is parallel to the front panel of the server shell. The box ear plate adopts the traditional screw grounding method, that is, grounding holes are set on the box ear plate and connected to the metal shell of the server by screws.

[0004] The current structure places the ear panels parallel to the front panel of the server enclosure. However, as ear panels become smaller, the electronic components and ports required to be arranged on them become increasingly dense. Traditional screw hole grounding, EMC shielding, and electrostatic protection methods are extremely difficult to implement. Screws occupy a large area on the vertical board. Given the rigid constraints of increasingly dense ear profiles and shrinking board area, it is difficult to reserve sufficient area on the PCB to arrange the screw holes required for securing, shielding, and grounding. Faced with these conflicting demands, the existing ear panel screw holes, as a solution for ear mounting, severely limit the ability to further reduce the width of the ear module. Summary of the Invention

[0005] The utility model provides a server box ear component to solve the problem that the box ear plate of the current server box ear is grounded with bolts, which limits the reduction of the box ear size.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is a server box ear assembly, including a box ear shell, the box ear shell having a connection surface connected to the server shell, a box ear plate and a shielding shrapnel are provided inside the box ear shell, at least one end of the box ear plate is provided with a metallized copper layer, the metallized copper layer is in contact with the shielding shrapnel, and the shielding shrapnel can be electrically connected to the server shell; the box ear plate is parallel to the connection surface. In the box ear structure of this solution, a metallized copper layer with electrical conductivity is provided at both ends of the box ear plate. When the box ear plate is installed, it is made to contact the shielding shrapnel in the box ear shell, and the conductive characteristics of the shielding shrapnel are used to achieve a grounding connection with the server shell. Based on this, the box ear plate is improved from being perpendicular to the side of the server shell to being parallel to the side of the server shell. The width of the box ear plate no longer restricts the width of the box ear, and the size of the box ear can be further reduced. At the same time, there is no need to set a grounding bolt hole on the box ear plate, freeing up more space and allowing the provision of more functional interfaces.

[0007] As a preferred embodiment of a server ear assembly, the ear housing includes an ear bracket and an ear front cover. The back and first side of the ear front cover are open. The ear bracket is bent into an L-shape and includes a back panel and side panels, which respectively cover the back and first side of the ear front cover. The shielding spring is installed inside the ear front cover and mates with the front, second side, and top surface of the ear front cover. With this solution, the ear housing adopts a front-to-back two-part structure, facilitating the installation of internal structures. The shielding spring is multi-faceted, providing comprehensive shielding effect.

[0008] As a preferred solution for a server box ear assembly, a partition is further provided inside the box ear front cover. The partition is parallel to the top surface of the box ear front cover, and the shielding spring is also covered by the partition. The partition and the top plate of the box ear front cover are each provided with a slot on the opposing surface. A set of opposite sides of the box ear plate are respectively inserted into the slots, and the shielding spring is provided with a notch corresponding to the slots. With this solution, the box ear plate adopts a fixed form of card slot insertion, which is more convenient for assembly and disassembly. The box ear plate is fixed at both ends, has good position retention, strong vibration resistance, and good contact and seal with the shielding spring.

[0009] As a preferred solution for server box ear assemblies, the metallized copper layer is provided at both ends of the box ear plate, covering five sides of the end of the box ear plate. This solution provides a large coverage area of ​​the metallized copper layer, ensuring effective contact with the shielding spring and more stable grounding performance.

[0010] As a preferred solution for a server enclosure ear assembly, an insulating sheet is further provided on the inner side of the side panels of the enclosure ear bracket, located between the side panels and the enclosure ear plate. This solution, by providing an insulating sheet between the enclosure ear bracket side panels and the enclosure ear plate, prevents short circuits caused by components on the enclosure ear plate being too close to the enclosure ear bracket, thereby improving safety and further reducing the width of the enclosure ear assembly.

[0011] As a preferred solution for a server case ear assembly, the front edge of the ear plate is provided with multiple function buttons, the front of the ear shell is provided with cutouts corresponding to the function buttons, and the front of the ear shell is also provided with a character patch with light-transmitting areas corresponding to the function buttons. This solution improves the appearance of the ear assembly and makes the operation buttons more intuitive and easier to operate.

[0012] As a preferred solution for a server ear assembly, the ear shell is equipped with multiple heat-seal posts. The shielding spring has connection holes corresponding to the heat-seal posts. The heat-seal posts pass through the corresponding connection holes and are heat-seal-connected to the shielding spring. This solution utilizes heat-seal connection between the shielding spring and the ear shell, resulting in a tighter installation, suitable for the installation of thin parts, and less prone to loosening.

[0013] As a preferred solution for a server case ear assembly, the inner rear surface of the ear shell is provided with rivet screws for connecting to the chassis bracket. A flap window is provided on the lower front portion of the ear shell, directly opposite the rivet screws. A flap is installed in the flap window, and the flap is hingedly connected to the ear shell via a pin. A torsion spring is installed on the pin to keep the flap closed. With this solution, a flap structure is provided on the front of the ear shell at a position corresponding to the rivet screws. Once opened, the flap structure allows for easy access to the rivet screws, facilitating the connection of the server case ear assembly to the chassis bracket and serving as a force point for assembly and disassembly.

[0014] As a preferred solution for the server case ear assembly, the front edge of the side panel of the case ear bracket is provided with a latching protrusion, and the back edge of the front panel of the case ear front cover is provided with a slot corresponding to the position of the latching protrusion, and the latching protrusion is inserted into the slot. With this solution, the case ear bracket and the case ear front cover are more convenient to disassemble and assemble.

[0015] On the other hand, the present invention further provides a server, comprising a server housing, wherein the above-mentioned server case ear assembly is installed on a side of the server housing.

[0016] Through the above technical solutions, it can be seen that the advantages of the present invention are as follows: the present invention provides a solution that does not require the use of PCB board screw holes to fix the box ear plate. Based on the conductive characteristics of the ECM shielding shrapnel in the server box ear, a metallized copper layer is set at both ends of the box ear plate. After the box ear plate is installed, the metallized copper layer contacts the shielding shrapnel to achieve effective grounding function, while playing the role of ECM shielding and electrostatic protection. It gets rid of the traditional box ear plate that needs to be perpendicular to the side of the server shell to be fixed with screw holes. The box ear plate is parallel to the side of the server shell, which can greatly reduce the width of the server box ear assembly. With the help of the insulating sheet to prevent short circuit, safety is guaranteed. It can maximize the compression of the total width of the box ear and release a larger width space for the architectural layout of the entire server system. The local grounding method of the card slot is adopted. By designing a coated metallized copper layer on both sides of the box ear plate, while achieving the fixation of the box ear plate, multiple functional requirements such as EMC shielding, electrostatic protection and effective grounding are achieved.
