Abstract
Description
Technical Field
[0001] This utility model relates to the field of network communication equipment technology, and specifically to a dedicated network switching device. Background Technology
[0002] A network adapter is a device used to connect different network devices or network segments, playing a crucial role in network communication. It enables physical connections and signal conversion between different network interfaces, allowing various network devices to communicate and collaborate. For example, in enterprise networks, network adapters can connect computers, servers, switches, and other devices to build a complete network system, enabling data transmission and resource sharing. In data centers, network adapters can connect different racks, improving network reliability and scalability.
[0003] Currently, most network adapters use traditional RJ45 connectors and their female connectors for connection. Because these connectors use a snap-on design, the network cable is easily detached due to accidental contact or external force, which is detrimental to stability. Furthermore, ordinary network cable interfaces cannot meet the physical isolation requirements of dedicated communication scenarios and must be arranged according to standardized wiring sequences (such as T568A / B). Therefore, there is a risk of unauthorized devices accessing the network, and physical layer isolation cannot be achieved. In dedicated networks, complex encryption devices or custom switches are required, resulting in high deployment and maintenance costs. Utility Model Content
[0004] This utility model provides a dedicated network adapter to solve the problem that the press-type snap-on connector of the existing technology is easy to fall off and cannot achieve physical communication isolation.

[0007] As a preferred technical solution of this utility model, the fitting block is an L-shaped structure and consists of a horizontal insertion end and a vertical limiting end.
[0008] As a preferred technical solution of this utility model, the end of the insertion end is provided with an anti-pressing block that matches the shape between the crystal head and the pressing buckle, and the upper end surface of the insertion end is provided with a limiting protrusion that engages with the limiting slide groove.
[0009] As a preferred technical solution of this utility model, the shape of the limiting end matches the shape of the limiting groove, the upper surface of the limiting end is an inclined structure and gradually rises towards the side away from the insertion end, and the upper surface of the limiting end is provided with multiple anti-slip protrusions.
[0010] As a preferred embodiment of this utility model, the lower end face of the fitting block abuts against the upper end face of the crystal head and is slidably connected to the upper end face of the crystal head.

[0012] The advantages of this utility model compared with the prior art are as follows:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1:
[0024] As per the instruction manual Figure 1-4 As shown, a dedicated network adapter includes a network cable body 1, an RJ21 connector 2, and a female connector 3, wherein the RJ21 connector 2 and the female connector 3 are located at the two ends of the network cable body 1, and a push-button latch 4 is provided above the RJ21 connector 2.
[0025] In this utility model, the crystal head 2 is provided with a fixing head 5 at one end near the network cable body 1, and one end of the fixing head 5 is fixedly connected to the crystal head 2, and the other end is fixedly connected to the network cable body 1.
[0026] In this utility model, the top of the fixing head 5 is provided with a limiting groove 6. The fixing head 5 is located near the crystal head 2 and is wrapped around the outside of the crystal head 2 in a C-shaped structure. The fixing head 5 is located at the limiting groove 6 with a C-shaped opening. The limiting groove 6 is slidably connected to a fitting block 7. The head of the fitting block 7 is located between the pressing buckle 4 and the crystal head 2. The lower end face of the fitting block 7 abuts against the upper end face of the crystal head 2 and is slidably connected to the upper end face of the crystal head 2.
[0027] In this utility model, the fitting block 7 is an L-shaped structure, consisting of a horizontal insertion end 8 and a vertical limiting end 9. The end of the insertion end 8 is provided with an anti-pressing block 10 that matches the shape between the crystal head 2 and the pressing buckle 4. The upper surface of the insertion end 8 is provided with a limiting protrusion 11 that engages with the limiting slide groove 6. The shape of the limiting end 9 matches the inside of the limiting slide groove 6. The upper surface of the limiting end 9 is an inclined structure that gradually rises toward the side away from the insertion end 8. At the same time, the upper surface of the limiting end 9 is provided with multiple anti-slip protrusions 12.
[0028] In this utility model, a decoding chip for adjusting the line sequence is embedded inside the female connector 3. The female connector 3 and the decoding chip are integrally injection molded. The decoding chip is a W5500 embedded Ethernet controller.
[0029] In a specific implementation, this utility model is modified by adding a fixing head 5 to the rear end of the crystal head 2, and the locking block 7 is slidably connected to the limiting groove 6 on the fixing head 5, so that after the crystal head 2 is inserted, the locking block is pushed to the bottom of the pressing buckle 4 for limiting, thus preventing the network cable from accidentally falling off.
[0030] Meanwhile, the RJ45 female connector uses a non-standard wire sequence at ends 2 and has a built-in decoding chip at end 3, which adjusts the wire sequence at ends 2 to another non-standard wire sequence. Communication can only be established when both ends use matching wire sequences, thus achieving physical isolation and ensuring the security of the dedicated communication network.
