Description

Technical Field

[0001] This utility model belongs to the field of computer peripheral devices, and in particular relates to an integrated computer USB expansion port. Background Technology

[0002] Integrated USB expansion ports on computers are an indispensable part of modern electronic devices, and their importance is self-evident. They cleverly overcome the limitations of the original number of USB ports on computers, bringing users unprecedented convenience and efficiency improvements. This integrated design, through precise circuit layout and efficient interface management, enables parallel connection and data transfer of multiple USB devices. Whether it's external storage devices, printers, or other various USB peripherals, they can all be easily connected, meeting the ever-growing and diverse needs of users.

[0003] Existing integrated computer USB expansion ports generally adopt a concave-convex connection method to realize the data transmission of multiple USB devices. This design realizes the physical connection of multiple USB expansion ports to a certain extent, enabling them to work together as a whole, thereby supporting the simultaneous access and data transmission of multiple USB devices.

[0004] However, the concave-convex mating method has revealed some shortcomings in practical applications. Due to its relatively simple structure, it lacks sufficient mechanical strength and stability. When the port is affected by external factors, such as accidental collisions, vibrations, or wear caused by long-term use, it is very easy for it to become loose. This loosening not only affects the tight connection between the ports, but may also lead to data transmission interruption or instability, which in turn negatively impacts the user experience and work efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an integrated computer USB expansion port to overcome the shortcomings in current practical applications. Utility Model Content

[0027] The engaging component 7 has one end mounted on the end wall of the middle port 3 and the tail port 4 on the side away from the cavity 10, and the other end engaged with the connecting slots 8 opened on the inner wall of the cavity 10 of the head port 2 and the middle port 3, respectively. By cooperating with the connecting slots 8, the engaging component 7 can connect the head port 2 and the middle port 3, the middle ports 3 with each other, and the middle port 3 and the tail port 4 into a whole, so that the head port 2, the middle port 3 and the tail port 4 will not easily detach, thereby ensuring the stability of the electrical connection between the head port 2, the middle port 3 and the tail port 4. This not only improves the practicality of the USB expansion port, but also demonstrates the ingenuity and refinement of the design, providing users with a more stable and reliable user experience, and also provides convenience for subsequent maintenance and upgrades, showing the foresight and innovation of the design.

[0028] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the connection module 9 includes a USB connector 91 and a USB port 92. The USB interfaces 5 are all installed in the cavities 10 of the head port 2 and the middle port 3. The USB connectors 91 are all installed on the end walls of the middle port 3 and the tail port 4 on the side away from the cavity 10.

This design transforms the ports from isolated entities into an organic whole, contributing to the expansion of the computer's USB ports. This connection method is not only stable and reliable but also greatly expands the number and scope of computer USB ports, meeting users' needs for multiple interfaces and high expandability.

[0030] In a preferred embodiment, the USB connector 91 and USB port 92 on the connection module 9 can be changed to other electrical connection combinations that meet the actual requirements, and are not limited to the USB connector 91 and USB port 92.

[0031] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the engaging assembly 7 includes a locking screw 71, a fixing platform 72, a connecting block 73, and an engaging groove 74. The locking screw 71 is screwed onto both ends of the end wall on the side away from the cavity 10 at the middle port 3 and the tail port 4, respectively. The fixing platform 72 is fixed on the locking screw 71. The fixing platform 72 cooperates with the engaging groove 74 opened at one end of the connecting block 73. One end of the connecting block 73 is respectively set at both ends of the end wall on the side away from the cavity 10 at the middle port 3 and the tail port 4, and the other end of the connecting block 73 cooperates with the connecting groove 8 on the head port 2 and the middle port 3, respectively.

[0032] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the fixed platform 72 preferably adopts a frustum-shaped block structure, the engaging groove 74 preferably adopts a frustum-shaped groove, and the inclination angle of the inner wall of the engaging groove 74 is consistent with the inclination angle of the outer wall of the fixed platform 72.

[0033] like Figures 1 to 3As shown in the preferred embodiment of this utility model, a protrusion is provided on one end of the connecting block 73 that cooperates with the connecting groove 8.

[0034] In this embodiment, the tilt angle of the connecting block 73 in its free state can be adjusted according to the diameter of the inner wall of the cavity 10, so that the connecting block 73 can stably cooperate with the connecting groove 8. After the tilt angle of the connecting block 73 is adjusted, the locking screw 71 is tightened. The locking screw 71 drives the fixed platform 72 on it to move. The fixed platform 72 cooperates with the engaging groove 74 on the connecting block 73 by moving. This can fix the connecting block 73 so that it will not deflect when it enters the cavity 10, but can only bend by its own elasticity, thereby achieving quick engagement with the connecting groove 8. At the same time, it can ensure the connection stability between it and the connecting groove 8, thereby improving the connection stability between the middle port 3 and the head port 2 or the tail port 4.

[0035] The connecting block 73, in conjunction with the connecting slot 8, can connect the head port 2 and the middle port 3, the middle ports 3 with each other, and the middle port 3 and the tail port 4 into a whole. This prevents the head port 2, the middle port 3, and the tail port 4 from easily disengaging, thus ensuring the stability of the electrical connection between them. This not only improves the practicality of the USB expansion port but also demonstrates the ingenuity and sophistication of the design, providing users with a more stable and reliable user experience. It also facilitates subsequent maintenance and upgrades, showcasing the forward-thinking and innovative nature of the design.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
