Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to an adjustable high-precision ultra-thin circuit board. Background Technology

[0002] A circuit board is a type of printed circuit board (PCB). It is manufactured with a slot that can be inserted into the slot of the computer's main circuit board (motherboard) to control the operation of hardware such as monitors and capture cards. After installing the driver, the corresponding hardware functions can be realized.

[0003] In the prior art, Chinese patent CN210864560U proposes a high-speed CPCIE storage board. Two baffles are pressed towards each other, causing two sliding rods to move towards each other, disengaging two card blocks from their respective slots. This allows users to move a second card plate. When the second card plate is moved to the appropriate position, it avoids situations where the card's latches cannot match the slots, thus meeting user needs. However, in practical applications, the connectors on the top of existing ultra-thin boards are fixed to the board, making it impossible to replace them later. Damage to the connectors can lead to the board becoming unusable. Therefore, we disclose an adjustable high-precision ultra-thin board. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose an adjustable high-precision ultra-thin board to solve the problem of the inability to replace the connector.

[0005] To achieve the above objectives, this utility model provides an adjustable high-precision ultra-thin board, comprising a board, a first connector fixedly connected to the top of the board, a plug connector movably engaged in the middle of the first connector, a second connector fixedly connected to the top of the plug connector, extension frames movably sleeved below both ends of the second connector, a plurality of limiting blocks fixedly connected to the outer wall of the second connector, and a plurality of first limiting grooves opened on one side of the inner wall of the extension frame, the first limiting grooves being movably engaged with the limiting blocks.

[0006] Preferably, the second connector has movable grooves on both sides, and a first limiting strip is slidably connected in the movable groove, and the first limiting strip is fixedly connected to the extension frame.

[0007] Preferably, the bottom end of the extension frame is provided with a movable hole, and a second limiting strip is fixedly connected to both sides of the first connector. The second limiting strip passes through the movable hole into the extension frame. The bottom end of the inner wall of the second connector is provided with a second limiting groove, and the second limiting groove is movably engaged with the second limiting strip.

[0008] Preferably, both the second connector and the extension bracket are U-shaped.

[0009] Preferably, the first connector has an interface in the middle, and the interface is movably engaged with the plug connector.

[0010] Preferably, the connector is located above the first connector.

[0011] The beneficial effects of this utility model are as follows: the position of the first connector is fixed by the board, and the first connector is connected to the second connector through the plug connector, so that the second connector can be connected to the external interface. This allows the user to replace the second connector with different external interfaces according to the needs of the user, meet the user's various usage needs, and improve the practicality of the board. When the second connector and the extension bracket slide from one end of the first connector to the other, the second limiting strip slides within the moving hole, restricting the sliding direction of the extension bracket and the second connector. After the second connector and the extension bracket slide to the required position, the second connector is pressed downwards, causing the plug to engage with the first connector and also causing the second limiting groove to engage with the second limiting strip. This causes the second connector to move into the extension bracket, making it difficult for the second connector to be pulled upwards during use. As a result, the engagement between the plug and the first connector is more stable and easier to use. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0016] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0017] like Figures 1-3As shown, an adjustable high-precision ultra-thin circuit board includes a circuit board 1. A first connector 2 is fixedly connected to the top of the circuit board 1. A plug connector 4 is movably engaged with the middle of the first connector 2. A second connector 3 is fixedly connected to the top of the plug connector 4. Extension frames 5 are movably sleeved at both ends of the second connector 3. Several limiting blocks 7 are fixedly connected to the outer wall of the second connector 3. Several first limiting grooves 6 are formed on one side of the inner wall of the extension frame 5. The first limiting grooves 6 are movably engaged with the limiting blocks 7. Both the second connector 3 and the extension frame 5 are U-shaped. An interface is provided in the middle of the first connector 2, and the interface is movably engaged with the plug connector 4. The connector 4 is located above the first connector 2. In use, the first connector 2 is fixedly connected to the top of the board 1, thus fixing the position of the first connector 2. The connector 4 is movably snapped into the middle of the first connector 2. The top of the connector 4 is fixedly connected to the second connector 3, allowing the first connector 2 to connect to the second connector 3 via the connector 4. This enables the second connector 3 to connect to an external interface, allowing users to replace the second connector 3 with different external interfaces as needed, meeting various user requirements and improving the practicality of the board 1. The lower ends of both sides of the second connector 3... An extension frame 5 is movably connected to the second connector 3. Several limiting blocks 7 are fixedly connected to the outer wall of the second connector 3. Several first limiting grooves 6 are formed on one side of the inner wall of the extension frame 5. The first limiting grooves 6 movably engage with the limiting blocks 7, allowing the extension frame 5 to restrict the position of the limiting blocks 7 via the first limiting grooves 6, thereby restricting the position of the second connector 3. This ensures that the second connector 3 maintains a certain height from the first connector 2, guaranteeing that when the relative position of the connector 4 and the first connector 2 has not reached the insertion position, the connector 4 is positioned above the first connector 2, preventing damage to the connector 4 during the movement of the second connector 3. Both the second connector 3 and the extension bracket 5 are U-shaped, which facilitates the connection between the second connector 3 and the extension bracket 5 and makes the relative position of the second connector 3 and the first connector 2 stable after connection. The first connector 2 has an interface in the middle, which is movably engaged with the plug 4. The plug 4 is located above the first connector 2, so that the plug 4 does not disengage from the first connector 2 when the second connector 3 moves, thus avoiding damage to the plug 4. Then the first connector 2 connects to the second connector 3 through the plug 4, so that the second connector 3, the first connector 2 and the plug 4 are combined into an adjustable plug for easy use.

[0018] As a preferred embodiment of this example, Figure 2 and Figure 3As shown, the second connector 3 has movable grooves 8 on both sides, and a first limiting strip 9 is slidably connected in the movable groove 8. The first limiting strip 9 is fixedly connected to the extension frame 5. The bottom end of the extension frame 5 has a movable hole 10. The first connector 2 has a second limiting strip 11 fixedly connected in both sides, and the second limiting strip 11 passes through the movable hole 10 into the extension frame 5. The bottom end of the inner wall of the second connector 3 has a second limiting groove 12, which is movably engaged with the second limiting strip 11. The movable grooves 8 on both sides of the second connector 3, with the first limiting strip 9 slidably connected in the movable groove 8 and fixedly connected to the extension frame 5, restrict the movement of the second connector 3 through the first limiting strip 9 and the movable grooves 8, thus preventing the connection between the extension frame 5 and the second connector 3 from being broken and ensuring the normal use of the extension frame 5. The first connector 2 has a movable hole 10, and two sides are fixedly connected to a second limiting strip 11. The second limiting strip 11 passes through the movable hole 10 into the extension frame 5. The bottom end of the inner wall of the second connector 3 is provided with a second limiting groove 12. The second limiting groove 12 is movably engaged with the second limiting strip 11, so that when the second connector 3 and the extension frame 5 slide from one end of the first connector 2 to the other end, the second limiting strip 11 slides in the movable hole 10, restricting the sliding direction of the extension frame 5 and the second connector 3. After the second connector 3 and the extension frame 5 slide to the required position, the second connector 3 is pressed down, so that the plug 4 is engaged with the first connector 2, and the second limiting groove 12 is engaged with the second limiting strip 11, so that the second connector 3 moves into the extension frame 5. This makes it difficult for the second connector 3 to be pulled upward during use, thus making the engagement between the plug 4 and the first connector 2 more stable and convenient to use.
