[0036] However, existing connection devices are often one-piece structures. Maintenance personnel often need to disassemble the entire device when performing maintenance, which not only increases the complexity and time cost of repairs but may also lead to cable damage or loosening, thus affecting the stability of signal transmission. Even if the connection device adopts a split structure, its internal components (such as cables and circuit boards) may wobble or shift due to the lack of effective fixing and limiting structures, thereby affecting the stability and reliability of signal transmission.

[0037] Therefore, there is an urgent need for a connection device to solve the above-mentioned technical problems.

[0038] like Figures 1-7As shown, this embodiment provides a connecting device, which includes: an outer shell 1, a mounting cover 2, and an inner shell 3. The outer shell 1 is provided with a mounting port 11 and a mounting cavity 12. A plug-in portion 13 is provided at the mounting port 11, and the mounting cavity 12 is connected to the outside through the mounting port 11. The mounting cover 2 is provided with a snap-fit ​​portion 21 and an interface 22. The snap-fit ​​portion 21 is correspondingly snapped into the plug-in portion 13 to detachably cover the mounting cover 2 at the mounting port 11. The inner shell 3 is provided with a limiting hole 31 and is disposed in the mounting cavity 12. An accommodating space 32 is formed between the outer shell 1, the inner shell 3, and the mounting cover 2. A circuit board 100 is disposed in the accommodating space 32. The inner shell 3 is limited between the outer shell 1 and the snap-fit ​​portion 21. The interface 22 is electrically connected to the circuit board 100, and a cable 200 electrically connected to the circuit board 100 passes through the limiting hole 31.

[0039] In this embodiment, the outer shell 1 is provided with a mounting port 11 and a mounting cavity 12. A plug-in portion 13 is provided at the mounting port 11, and the mounting cavity 12 is connected to the outside through the mounting port 11. The mounting cover 2 is provided with a snap-fit ​​portion 21 and an interface 22. The snap-fit ​​portion 21 is correspondingly snapped into the plug-in portion 13, allowing the mounting cover 2 to be detachably sealed to the mounting port 11. This facilitates quick assembly and disassembly of the connecting device by operators. Furthermore, operators can maintain various components within the connecting device through the mounting port 11, thus reducing the complexity and time cost of assembly and maintenance. The inner shell 3 is disposed within the mounting cavity 12, forming an accommodating space 32 between the outer shell 1, the inner shell 3, and the mounting cover 2. A circuit board 100 is disposed within the accommodating space 32 to protect and limit the circuit board 100, preventing it from shaking or shifting. The inner shell 3 is confined between the outer shell 1 and the snap-fit ​​portion 21, thus limiting the inner shell 3 and improving the overall structural stability of the device. Interface 22 is electrically connected to circuit board 100. The inner housing 3 has a limiting hole 31 through which a cable 200 electrically connected to circuit board 100 passes, effectively fixing and limiting the cable 200 to ensure the stability and reliability of signal transmission. Through the above configuration, the connection device of this embodiment is easy to disassemble and maintain, improving stability and reliability.

[0040] The specific structure of the connecting device is described below:

[0041] Specifically, both the outer shell 1 and the inner shell 3 are roughly U-shaped groove structures, and the cross-section of the inner shell 3 is L-shaped. The mounting cover 2 is a plate-like structure. The outer shell 1, the mounting cover 2 and the inner shell 3 are interconnected to form a stable accommodating space 32, which facilitates the installation and fixation of the circuit board 100 and the cable 200.

[0042] Specifically, multiple interfaces 22 are provided, spaced apart on the mounting cover 2. These interfaces 22 are used to connect connectors (such as USB or HDMI) to meet the insertion requirements of different types of connectors, thereby improving the versatility and flexibility of the connection device. The number of interfaces 22 can be two, three, or four; no specific limit is placed on the exact number of interfaces 22.

[0043] Specifically, the outer casing 1 has multiple insertion portions 13 along the circumference of the mounting opening 11, and the mounting cover 2 has multiple snap-fit ​​portions 21 spaced apart along its own circumference. The multiple snap-fit ​​portions 21 are snapped into the multiple insertion portions 13 in a one-to-one correspondence, thereby realizing the detachable connection between the mounting cover 2 and the outer casing 1 and improving the efficiency of disassembly and assembly. Moreover, the outer casing 1 has a support portion 18 along the circumference of the mounting opening 11, and a support portion 18 is provided between every two adjacent insertion portions 13. The support portion 18 is configured to abut against the side of the mounting cover 2 facing the outer casing 1, providing additional support for the mounting cover 2, thereby enhancing the structural stability between the mounting cover 2 and the outer casing 1.

[0044] More specifically, in this embodiment, the plug-in portion 13 is a socket, and multiple sockets are arranged at intervals along the circumference of the mounting opening 11; the snap-fit ​​portion 21 is a spring clip, which snaps into the socket, thus achieving quick snap-fit ​​and disassembly through the mutual cooperation of the spring clip and the socket, making the operation simpler and more convenient. Moreover, the support portion 18 is a protruding edge, which extends circumferentially along the mounting opening 11. The support portion 18 supports the side of the mounting cover 2 facing the outer shell 1, further enhancing the stability of the mounting cover 2 and avoiding signal transmission instability caused by the loosening of the mounting cover 2.

[0045] Specifically, the inner wall of the inner housing 3 is provided with a fixing groove 33, and the circuit board 100 is inserted into the fixing groove 33, which can effectively fix the circuit board 100, prevent it from shaking or shifting inside the device, and ensure the stability of signal transmission.

[0046] Specifically, the outer wall of the inner shell 3 is recessed towards the circuit board 100 to form an inward portion 34. A through space 341 is formed between the inward portion 34 and the outer shell 1. The cable 200 is passed through the through space 341 to facilitate the wiring and management of the cable 200 and avoid the cable 200 being messy and difficult to maintain.

[0047] More specifically, the inner portion 34 is provided with an abutment 342 facing the inner wall of the circuit board 100. The abutment 342 abuts against the circuit board 100, thereby further stabilizing the circuit board 100 and preventing it from shifting inside the device, thus avoiding unstable signal transmission caused by the loosening of the circuit board 100.

[0048] Specifically, the cable 200 is provided with a limiting part 201, which is snapped into the limiting hole 31 to effectively fix the cable 200, prevent the cable 200 from loosening or shaking inside the device, and ensure the stability of the cable 200 and the reliability of signal transmission.

[0049] More specifically, in this embodiment, the limiting part 201 includes two limiting plates sleeved on the outer peripheral wall of the cable 200. The two limiting plates face each other and are spaced apart. A positioning groove is formed between the two limiting plates for locking into the limiting hole 31. The above arrangement can not only effectively fix the cable 200, but also facilitate the installation and disassembly of the cable 200, making the operation simpler and more convenient.

[0050] Specifically, the inner wall of the outer casing 1 is provided with a limiting groove 14 for clamping the cable 200. By setting the limiting groove 14 to further clamp the cable 200, the stability of the cable 200 and the reliability of signal transmission can be ensured, and the cable 200 can be prevented from loosening or shaking inside the device.

[0051] Specifically, the connecting device also includes fasteners. The inner wall of the mounting cavity 12 is provided with a connecting post 15, and the inner shell 3 is provided with a connecting hole 35. The fasteners pass through the connecting hole 35 and are connected to the connecting post 15 to lock the outer shell 1 and the inner shell 3 together, thereby enhancing the stability of the overall structure of the device.

[0052] The fasteners can be screws or threaded rods, as long as they can achieve the above functions. No specific restrictions are placed on the structure of the fasteners.

[0053] Specifically, the inner shell 3 is recessed into the outer shell 1 and has a fastening groove 36. The connecting post 15 is inserted into the fastening groove 36. The connecting hole 35 is opened at the bottom of the fastening groove 36 and aligned with the opening of the connecting post 15. The fastener passes through the connecting hole 35 and is connected to the opening of the connecting post 15, so as to facilitate disassembly and maintenance by operators. Moreover, the fastening groove 36 is provided with multiple fastening ribs 361 at intervals along its circumference, which can further enhance the fixing effect of the fastener and ensure a more secure connection between the outer shell 1 and the inner shell 3.

[0054] Specifically, the mounting cavity 12 is provided with a support member 16 facing the inner wall of the circuit board 100. The support member 16 is used to stabilize and support the circuit board 100, thereby ensuring the stability of the circuit board 100 within the accommodating space 32 and preventing the circuit board 100 from shaking or shifting, so as to ensure the stability of signal transmission.

[0055] More specifically, the mounting cavity 12 is provided with a connector 17 on the inner wall facing the circuit board 100. The connector 17 connects two adjacent support members 16 to form an integral structure, thereby further enhancing the stability of the support members 16 and ensuring the stable support of the circuit board 100.

[0056] More specifically, in this embodiment, the support member 16 is a support plate, and two support plates are arranged facing each other and spaced apart on the inner wall of the outer shell 1. The connector 17 is a connecting plate, which is arranged between the two support plates. The two ends of the connecting plate are respectively connected to the two support plates, thereby enhancing the connection strength between the two support plates, ensuring the stability of the overall structure, and preventing the circuit board 100 from shifting or moving.

[0057] Specifically, the connector 17 is recessed in the direction away from the circuit board 100 to form a relief groove 171. The relief groove 171 at least partially avoids the circuit board 100, thereby providing sufficient space for the circuit board 100 and its electrical components, and avoiding interference between the connector 17 and the circuit board 100, which would affect the assembly operation.

[0058] Specifically, the outer casing 1 is provided with a fixing hole 19, and the connecting device also includes a locking member, which passes through the fixing hole 19 and is connected to the mounting surface, so as to lock the outer casing 1 to the mounting surface. This arrangement allows the device to be firmly installed on the mounting surface, thereby improving the stability and reliability of the device during use.

[0059] The locking component can be a screw or a threaded rod. The specific structure of the locking component is not limited here, as long as it can achieve the above-mentioned functions.
