Description

Technical Field

[0001] This utility model belongs to the field of computer science, and specifically relates to a magnetic expansion interface module device for minicomputers. Background Technology

[0002] Mini computers are widely used in office and entertainment scenarios due to their small size, portability, and low power consumption. However, due to size limitations, they usually have a limited number of interfaces, making it difficult to meet the needs of connecting multiple peripherals at the same time. Magnetic expansion interface module devices, as an auxiliary device, provide a convenient peripheral expansion solution for mini computers by expanding the number of interfaces and using a magnetic connection method.

[0003] Currently, most minicomputer expansion interface modules use traditional plug-in connections. Repeated plugging and unplugging can easily cause wear and tear on the computer's interface, leading to loose connections. Furthermore, the disassembly and assembly operations are cumbersome and cannot be done quickly, affecting the ease of use of the device. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic expansion interface module device for minicomputers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnetic expansion interface module device for a mini computer includes a USB connector, an expansion connector, and a protective shell. The expansion connector has a USB interface inside. The protective shell is movably mounted on one end of the expansion connector. The protective shell has a rectangular groove inside, and a sealing layer is provided on the inner side of the rectangular groove. A locking block is fixedly connected to one end of the protective shell. A magnetic connector is fixedly connected to the other end of the expansion connector. A USB connector is movably mounted on one end of the magnetic connector. A magnetic ring is provided at one end of the USB connector on both sides of the magnetic ring. Magnetic blocks are fixedly connected to one end of the USB connector on each side of the magnetic ring.

[0007] Preferably, the other end of the expansion connectors on both sides of the USB connector is fixedly connected to a metal block, and the magnetic block is fitted into the metal block.

[0008] Preferably, there are three USB ports and three rectangular slots.

[0009] Preferably, the expansion connectors on both sides of the USB interface are provided with limiting holes, and the locking blocks are fitted into the expansion connectors.

[0010] Preferably, pull blocks are fixedly connected to both sides of the protective shell, and the pull blocks are made of silicone rubber.

[0011] Preferably, a label is provided on the top of the expansion connector, and the label is made of organic resin material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects multiple peripheral connectors to the three USB ports of the expansion connector, using the USB connectors to connect to the mini-computer interface. It also achieves a stable connection through the dual magnetic attraction of the magnetic ring and magnetic block of the magnetic connector and the USB connector, ensuring normal data transmission and power supply between the peripherals and the mini-computer. Furthermore, it facilitates quick installation and removal of multiple peripheral connectors, significantly improving ease of operation and reducing wear and tear on the computer interface caused by repeated plugging and unplugging.

[0014] This utility model installs a protective shell on the end of the expansion connector with a USB interface, allowing the locking block to fit and be fixed with the limiting hole. The three rectangular slots correspond to the USB interface, and the rubber sealing layer inside the rectangular slots tightly wraps the connection position between the peripheral connector and the expansion connector, effectively protecting the connection position. This prevents external liquid from entering, reduces the impact of external impact, avoids damage or detachment of the peripheral connector, and ensures the stable use of the device.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: This example provides a magnetic expansion interface module device for a mini computer, including a USB connector 1, an expansion connector 2, and a protective shell 3. The expansion connector 2 has a USB interface 203 inside. The protective shell 3 is movably mounted on one end of the expansion connector 2. The protective shell 3 has a rectangular groove 302 inside, and a sealing layer 304 is provided on the inner side of the rectangular groove 302. A locking block 303 is fixedly connected to one end of the protective shell 3. A magnetic connector 5 is fixedly connected to the other end of the expansion connector 2. A USB connector 1 is movably mounted on one end of the magnetic connector 5. A magnetic ring 101 is provided on one end of the USB connector 1. Magnetic blocks 102 are fixedly connected to one end of the USB connector 1 on both sides of the magnetic ring 101. Metal blocks 4 are fixedly connected to the other ends of the expansion connectors 2 on both sides of the USB connector 1, and the magnetic blocks 102 and metal blocks 4 are fitted together. Three USB interfaces 203 are provided, three rectangular grooves 302 are provided, and limit holes 202 are provided inside the expansion connectors 2 on both sides of the USB interfaces 203, with the locking blocks 303 fitting together with the expansion connectors 2.

[0026] Users can insert multiple peripheral connectors into the three USB ports 203 of the expansion connector 2, then insert the USB connector 1 into the mini computer's interface, and then connect the magnetic connector 5 at the other end of the expansion connector 2 to the USB connector 1. At this time, the magnetic ring 101 on the USB connector 1 will form a magnetic connection with the magnetic connector 5, and the magnetic block 102 at one end of the USB connector 1 will also attract and fit with the metal block 4 on the expansion connector 2. A stable connection is achieved through the double magnetic attraction, which not only ensures normal data transmission and power supply between peripherals and mini computer, but also makes it easy for users to quickly install and remove multiple peripheral connectors, improving the ease of operation.

[0027] When protection of the interface and peripheral connector is required, the protective shell 3 can be installed on the end of the expansion connector 2 with the USB interface 203. The locking block 303 on the protective shell 3 will engage with the limiting hole 202 inside the expansion connector 2, so that the protective shell 3 is stably fixed. The three rectangular slots 302 inside the protective shell 3 correspond one-to-one with the three USB interfaces 203. With the rubber sealing layer 304 on the inner side of the rectangular slots 302, the connection position between the peripheral connector and the expansion connector 2 can be tightly wrapped, which can provide physical protection for the peripheral connector, effectively prevent external liquid from entering, and reduce the impact of external impact on the connection part, so as to avoid damage or detachment of the peripheral connector and ensure the stable use of the device.

[0028] Example 2: This example is basically the same as the previous example, except that pull blocks 301 are fixedly connected to both sides of the protective shell 3, and the pull blocks 301 are made of silicone rubber.

[0029] The staff member holds the pull block 301 and pulls to remove the protective shell 3. The pull block 301 increases the friction between the staff member's fingers and the protective shell 3, making it easier for the staff member to remove the protective shell 3.

[0030] Specifically, the top of the expansion connector 2 is provided with a label 201, and the label 201 is made of organic resin material.

[0031] Label 201 has an interface identification mark, which makes it easy for staff to observe the connector model of expansion connector 2.
