Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic equipment technology, and specifically relates to a card insertion guide structure. Background Technology
[0002] In modern industrial production and daily life, there are various ways to connect different types of equipment and components. Among them, the plug-in connection is widely used in many fields, such as electronic equipment, mechanical equipment, and furniture manufacturing, due to its convenience and efficiency. The plug-in connection achieves the connection and collaborative work of the two by inserting one component (plug-in card) into another component (slot or card holder). This connection method has the advantages of simple installation, small space occupation, and easy maintenance and replacement of components.
[0003] The existing traditional card-type connection structure has a prominent problem: it requires high alignment accuracy between the card and the slot. In practice, users often need to spend a lot of time and effort to accurately align the card and the slot to complete the connection. For example, in some small electronic devices, the internal memory card slot and memory card are tiny, and the pins of the slot and the contacts of the memory card correspond with extremely high precision. Even a slight deviation may cause the memory card to fail to be inserted properly or to have poor contact after insertion, affecting the normal use of the device. This is difficult for users who are not familiar with the operation, and they are prone to damaging the card or slot during repeated attempts to insert it. Utility Model Content
[0004] The purpose of this invention is to provide a card insertion guide structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a card insertion guide structure, comprising:
[0006] A first guide limiting block, a second guide limiting block is provided on one side of the first guide limiting block, the first guide limiting block and the second guide limiting block are assembled together by limiting components, the first guide limiting block and the second guide limiting block are provided with an insertion port in the middle, and one end of the insertion port is provided with a guide slot for guiding the insertion card and the guide slot is set in an inclined shape.
[0007] Preferably, the other end of the socket is provided with a limiting groove for installing a socket, and one end of the insert is inserted into the socket under the guidance of the guide slot and then plugged into the socket in the limiting groove.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides, for example Figure 1-3 The card insertion guide structure shown includes:
[0021] A first guide limiting block 1 is provided, and a second guide limiting block 2 is provided on one side of the first guide limiting block 1. The first guide limiting block 1 and the second guide limiting block 2 are assembled together by limiting components. An insertion port 3 is provided in the middle of the first guide limiting block 1 and the second guide limiting block 2. One end of the insertion port 3 is provided with a guide slot 4 for guiding the insertion card, and the guide slot 4 is set in an inclined shape.
[0022] The other end of the socket 3 is provided with a limiting groove 5 for installing a socket. One end of the insert card is inserted into the socket 3 under the guidance of the guide slot 4 and then plugged into the socket in the limiting groove 5.
[0023] The limiting component includes a limiting plug 6, which is provided in several groups and is respectively connected to both sides of the first guide limiting block 1 and the second guide limiting block 2. The first guide limiting block 1 and the second guide limiting block 2 are also provided with limiting slots 7 on both sides. During the assembly process, the operator can quickly align the limiting plug 6 with the limiting slot 7 and insert it to complete the assembly of the first guide limiting block 1 and the second guide limiting block 2. Moreover, when the equipment is repaired or upgraded, if it is necessary to disassemble the guide structure, the limiting plug 6 can be easily pulled out from the limiting slot 7. The operation is simple and convenient, which improves production and maintenance efficiency.
[0024] The limiting block 6 on the second guide limiting block 2 is slidably inserted into the limiting slot 7 inside the first guide limiting block 1.
[0025] The first guide limit block 1 and the second guide limit block 2 are connected to a plurality of first limit posts 8, and the first guide limit block 1 and the second guide limit block 2 are also provided with fixing grooves 9. By passing screws or bolts through the fixing grooves 9 and tightening them into the corresponding threaded holes on the equipment or circuit board, the first guide limit block 1 and the second guide limit block 2 can be firmly fixed on the equipment or circuit board.
[0026] One end of the first guide limiting block 1 and the second guide limiting block 2 is connected to a second limiting post 10, and a fixing hole 11 for fixing the socket is provided on one side of the second limiting post 10. The second limiting post 10 can be inserted into the corresponding hole on the external device or circuit board to provide initial positioning for the guide structure. The setting of the fixing hole 11 allows the socket to be firmly fixed in the limiting groove 5 using screws or other connectors.
[0027] In actual operation, the user places the card near the entrance of the guide slot 4. The guide slot 4 is inclined. When the card contacts the guide slot 4, the card will be supported by the inclined surface. As the card is pushed to move along the direction of the guide slot 4, the card gradually fits against the inner wall of the guide slot 4. Even if there is a certain deviation in the initial placement position of the card, such as a slight offset to the left or right or up or down, the card will be gradually guided to the correct insertion path under the continuous action of the inclined guiding force. As the card goes deeper into the guide slot 4, it will be completely inserted into the socket 3.
[0028] After the card enters the socket 3 along the guide slot 4, the connecting part of the card can accurately correspond to the corresponding contact or interface in the socket installed in the limiting groove 5 at the other end of the socket 3 due to the guiding effect of the guide slot 4. As the card continues to be pushed in, the metal pins on the card will achieve good electrical connection with the metal spring or contact in the socket, thereby ensuring a stable connection between the card and the socket, and thus realizing functions such as data transmission, signal transmission or mechanical linkage. In addition, the first guide limiting block 1 and the second guide limiting block 2 can also be used for vertical and horizontal installation according to actual installation needs, meeting the design requirements of various devices.
[0029] The first guide limiting block 1 and the second guide limiting block 2 are assembled using a limiting component. Limiting inserts 6 in the limiting component are connected to both sides of the two guide limiting blocks. Simultaneously, each side of the two guide limiting blocks has a corresponding limiting slot 7. During assembly, the limiting insert 6 on the second guide limiting block 2 is aligned with the limiting slot 7 on the first guide limiting block 1, and then the second guide limiting block 2 is pushed, causing the limiting insert 6 to slide into the limiting slot 7. This plug-and-play connection method not only ensures the two guide limiting blocks are securely joined together, but also makes disassembly for maintenance or component replacement very convenient. Furthermore, the first guide... The first limiting post 8 and fixing groove 9, as well as the second limiting post 10 and fixing hole 11 on the limiting block 1 and the second guide limiting block 2, are used to fix the entire card insertion guide structure to the external device or circuit board. During the installation process, the first limiting post 8 and the second limiting post 10 are inserted into the corresponding holes pre-set on the device or circuit board to play a preliminary positioning role and ensure the accurate position of the guide structure. Then, by installing screws or other connectors in the fixing groove 9, the guide structure is firmly fixed to the device, ensuring that the guide structure will not be displaced or shaken during the insertion and use of the card, thereby stably performing its guiding and connecting functions.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
