Description

Technical Field

[0001] This utility model relates to the field of insert box structure technology, specifically to an insert box board slot structure. Background Technology

[0002] In the electronics industry, the plug-in / plug-in architecture plays a crucial role, enabling the secure and stable installation of printed circuit boards (PCBs) within various electronic devices such as servers, communication equipment, and data center equipment. This architecture not only affects the overall stability and reliability of the equipment but also directly impacts its maintenance, upgrade, and expansion capabilities.

[0003] However, existing slot and card designs generally suffer from a fundamental problem: they often select guide rails with matching slot widths based on the thickness of the PCB board. While this design approach meets the basic requirements for PCB board mounting to some extent, it introduces numerous limitations and shortcomings.

[0004] Specifically, due to the wide variety of PCB thicknesses, ranging from ultra-thin to thick, traditional insert-and-card structures require the design and production of different models and shapes of guide rails for each PCB thickness. This "one-to-one" matching model results in extremely low versatility of guide rail components, making it impossible for PCBs of different specifications to share the same guide rail system. This not only increases the variety of guide rail components but also makes production management and inventory control extremely complex and cumbersome.

[0005] Furthermore, this design strategy introduces additional production and management costs. Due to the wide variety of guide rail components, more human and material resources are required in all stages of the production process, including mold development, material procurement, manufacturing, and quality inspection. Simultaneously, inventory management necessitates setting up independent inventory areas and management systems for each type of guide rail component, thus increasing inventory costs and management complexity.

[0006] More seriously, with the increasing diversification of PCB board specifications, traditional slot-and-play card structures are facing growing challenges. To adapt to different specifications and types of PCB boards, companies have to continuously develop and launch new guide rail components, which not only increases R&D investment and the speed of product updates, but may also lead to compatibility issues between products.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] like Figure 1-2 As shown, this application provides a card slot structure, including a slot body 1 and a key sheath 2 disposed on the slot body 1, wherein,

[0025] A baffle 11 is integrally formed on one side of the slot body 1, and a PCB slot 12 is left between the key sheath 2 and the baffle 11;

[0026] The bottom of the key sheath 2 is provided with a positioning pin 21, and the slot body 1 is provided with a corresponding positioning groove 13. The positioning pin 21 can slide freely in the positioning groove 13.

[0027] The slot body 1 is provided with a plurality of first screw holes 14, and the key sheath 2 is provided with a plurality of second screw holes 22. The first screw holes 14 are arranged obliquely, and the second screw holes 22 on the key sheath 2 are arranged horizontally. The key sheath 2 is fixed in different first screw holes 14 by first fastening screws 3 to accommodate PCB boards of different thicknesses.

[0028] In one possible implementation, a plurality of coded keys 15 are provided next to a plurality of the first screw holes 14, the coded keys 15 respectively indicating PCB boards of different thicknesses.

[0029] In an exemplary embodiment, the coded key 15 is not only provided with numerical or alphanumeric identifiers representing different PCB board thicknesses, but also provides additional visual cues through color coding or icons. For example, different colors can be used to represent different series of PCB boards, or icons can be used to intuitively display information such as the recommended installation direction and maximum supported size of the PCB board, so that users can quickly and accurately identify and select the appropriate installation configuration.

[0030] In one possible implementation, the slot body 1 is further provided with a third screw hole 16, through which the slot body 1 is fixed to the insertion box by the third screw hole 16 and the corresponding second fastening screw 4.

[0031] It is worth mentioning that the number, position, and diameter of the third screw holes can be flexibly adjusted according to the specific structure and design requirements of the insertion box to adapt to different models, specifications, and installation methods of the insertion box. For example, multiple spare screw hole positions can be reserved on the side or bottom of the insertion box, and users can choose the appropriate hole position for fixing and installation according to actual needs, thereby improving the versatility and flexibility of the slot structure.

[0032] In one possible implementation, a guide structure is provided on the side edge of the slot body 1 away from the baffle. The guide structure is specifically a pair of parallel guide grooves, each guide groove extending along the length direction of the slot body. The width of the guide groove is slightly larger than the edge thickness of the PCB board to be inserted, but smaller than the overall width of the PCB board, so as to ensure that the PCB board can be guided by the guide groove during the insertion process and slide smoothly and accurately into the PCB slot, while preventing the PCB board from shaking in the width direction of the slot body.

[0033] In one possible implementation, the inner wall of the guide groove is made of a wear-resistant material with a low coefficient of friction, such as a polytetrafluoroethylene (PTFE) coating, to reduce the frictional resistance of the PCB board during sliding. At the same time, the opening edge of the guide groove is chamfered to avoid edge scratches when inserting the PCB board.

[0034] In one possible implementation, the key sheath 2 is made of a material with excellent elasticity and wear resistance, such as silicone or thermoplastic elastomer (TPE), to ensure that the key sheath can maintain its original shape and dimensional stability after repeated insertion and removal of the PCB board, thereby maintaining good contact tightness and positioning accuracy.

[0035] In one possible implementation, the positioning pin 21 is cylindrical in shape, with a diameter slightly smaller than the width of the positioning groove 13, to ensure that the positioning pin 21 can slide freely within the positioning groove 13 without generating excessive frictional resistance; at the same time, the surface of the positioning pin 21 is finely polished to achieve mirror-level smoothness, in order to further reduce friction and wear, and improve the smoothness of sliding and positioning accuracy.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
