[0076] It should be noted that as people pay more and more attention to network security, the security locking of network interface devices has gradually become a focus of attention for various equipment manufacturers.

[0077] In the related art, in order to achieve physical locking between a network interface device and a network cable connector, a specific network cable connector is usually customized to achieve locking and unlocking between the network interface device and the network cable connector. However, for an ordinary network cable connector, the connection and separation of the network cable connector and the network interface device can be achieved by pressing the spring tongue of the network cable connector. The network cable connector and the network interface device cannot be locked and unlocked without using an adapter. Anyone can plug and unplug the network cable connector and replace it by pressing the spring tongue, which greatly reduces the safety protection level of the ordinary network cable connector.

[0078] Based on this, the present application proposes a network interface device 100, which has an integrated locking member 2 and a limiting member 3. When the locking member 2 moves to the unlocked position, the network cable connector 200 can be directly inserted into the plug port 11 to achieve the connection between the network interface device 100 and the network cable connector 200. Then, the locking member 2 is moved to the locked position. The locking member 2 can prevent the network cable connector 200 inserted into the plug port 11 from detaching from the plug port 11, thereby locking the network cable connector 200. When it is necessary to unlock the network cable connector 200, the locking member 2 is moved back to the unlocked position to pull the network cable connector 200 out of the plug port 11. This locking method The invention is applicable to various common network cable connectors 200, that is, it can lock the common network cable connector 200 with the network interface device 100, thereby improving the safety protection level of the connection between the common network cable connector 200 and the network interface device 100, and when the network cable connector 200 is not plugged into the plug port 11, the locking member 2 can be moved to the locking position to prevent the network cable connector 200 from being inserted into the plug port 11, thereby realizing the active protection function of the network interface device 100, and at the same time, when the locking member 2 moves to the locking position, the limiting member 3 can also limit the locking member 2 when the locking member 2 moves to the locking position, thereby further improving the locking performance of the locking member 2 in the locking position, and further improving the safety protection level.

[0079] The network interface device 100 proposed in the embodiment of the present application is described below with reference to the accompanying drawings.

[0080] like Figure 1-Figure 10As shown, the network interface device 100 according to the first embodiment of the present application includes: a housing, a network interface body 1, a locking member 2, and a limiting member 3. The network interface body 1 is provided with a plug port 11 for connecting to a network cable connector 200. The network interface body 1 is fixed to the housing. The network interface body 1 also has an avoidance hole 12 connected to the plug port 11. The locking member 2 is movably arranged in the housing. The locking member 2 has a locking portion 21, and the locking portion 21 is suitable for selectively extending into the plug port 11 through the avoidance hole 12, so that the locking member 2 Move to the unlocking position or the locking position. When the locking member 2 is in the unlocking position, the network cable connector 200 is suitable for being inserted into the plug-in port 11 from the outside or being pulled out from the plug-in port 11. When the locking member 2 is in the locking position, the locking portion 21 cooperates with the network cable connector 200 to prevent the network cable connector 200 from being inserted into the plug-in port 11 or to prevent the network cable connector 200 inserted into the plug-in port 11 from being separated from the plug-in port 11. The limiting member 3 can be movably arranged in the shell, and the limiting member 3 is suitable for limiting the locking member 2 when the locking member 2 moves to the locking position.

[0081] Specifically, the network interface device 100 includes but is not limited to a switch, a host motherboard, a router, such as Figure 1-Figure 5 As shown, the network interface device 100 may include one network interface body 1, or may include multiple network interface bodies 1, which are specifically configured according to actual conditions and are not specifically limited herein. It can be understood that if the network interface device 100 includes multiple network interface bodies 1, each network interface body 1 has the same structural features, and each network interface body 1 is correspondingly provided with a locking member 2 and a limiting member 3.

[0082] Further, refer to Figure 6 As shown, the network interface body 1 includes a plug-in port 11 and an avoidance hole 12, wherein the plug-in port 11 is used to connect to the network cable connector 200, and the avoidance hole 12 is connected to the plug-in port 11. It should be noted that the avoidance hole 12 is arranged on the peripheral wall of the network interface body 1. For example, the avoidance hole 12 can be arranged on the top wall of the network interface body 1, or on the side wall of the network interface body 1, or on the rear wall of the network interface body 1. The specific arrangement is based on actual conditions and is not specifically limited here.

[0083] Further, in some embodiments of the present application, Figure 6 As shown, the avoidance hole 12 is arranged on the top wall of the network interface body 1 and is connected to the plug-in port 11 of the network interface body 1. The locking portion 21 of the locking member 2 is opposite to the position of the avoidance hole 12. The locking member 2 can move up and down in the shell so that the locking portion 21 of the locking member 2 can selectively extend into the plug-in port 11 or move out of the plug-in port 11 through the avoidance hole 12.

[0084] Furthermore, the locking member 2 can be moved to an unlocked position or a locked position. It can be understood that the unlocked position is the position where the locking member 2 stops restricting the network cable connector 200. The restriction methods include but are not limited to abutment limit, etc. Therefore, the unlocked position is not unique. For example, the locking portion 21 of the locking member 2 is constructed as a locking plate extending along the axial direction of the avoidance hole 12, or it can be a lock buckle that can be opened and closed up and down. When the locking portion 21 of the locking member 2 is moved out of the plug port 11 through the avoidance hole 12, the locking portion 21 has no obstruction for the network cable connector 200 to be inserted into the plug port 11 or pulled out from the plug port 11, so Any position corresponding to the locking portion 21 of the locking member 2 being moved out of the plug port 11 can be defined as the unlocked position. Furthermore, assuming that the locking portion 21 of the locking member 2 is not moved out of the plug port 11, but if the locking portion 21 of the locking member 2 does not block the network cable connector 200 from being inserted into the plug port 11 from the outside or being pulled out of the plug port 11, although the locking portion 21 is still located in the plug port 11, the position of the locking member 2 at this time is also the unlocked position; the locked position is the position where the locking member 2 restricts the network cable connector 200, and the restriction method includes but is not limited to abutment limit, etc. For example, Fig.10 As shown, the network cable connector 200 has a spring tongue 201 and a limiting portion 202, and the end face of the limiting portion 202 is consistent with the pull-out direction of the network cable connector 200. When the network cable connector 200 is inserted into the plug-in port 11, the locking member 2 is controlled to move and the locking portion 21 of the locking member 2 and the limiting portion 202 of the network cable connector 200 are abutted against each other or locked to limit the network cable connector 200 from being pulled out, thereby limiting the network cable connector 200 in the plug-in port 11. Of course, the locking portion 21 of the locking member 2 can also cooperate with other positions of the network cable connector 200 to limit, and examples are not given one by one here. When the locking portion 21 limits the limiting portion 202 of the network cable connector 200, the network cable connector cannot be pulled out by pressing the spring tongue 201, thereby achieving the locking of the network cable connector 200. Furthermore, the network interface device 100 also has an active protection function. When the network cable connector 200 is not inserted into the plug-in port 11, the locking member 2 can be controlled to move and the locking portion 21 of the locking member 2 can be extended into the plug-in port 11, wherein the length of the extension into the plug-in port 11 can ensure that the network cable connector 200 is prevented from being inserted into the plug-in port 11. In this way, the network cable connector 200 can be prevented from being inserted into the plug-in port 11 at will, thereby realizing active protection of the network interface device 100.

[0085] Furthermore, in order to enable those skilled in the art to better understand the present solution, the operation mode of the network interface device 100 is described in detail below by way of example. When the network interface device 100 needs to be connected to the network cable connector 200, the locking member 2 in the network interface device 100 is moved to the unlocked position. At this time, the locking portion 21 of the locking member 2 no longer restricts the plugging of the network cable connector 200. When the network cable connector 200 is plugged into the plug port 11, the locking member 2 in the network interface device 100 is controlled to move to the locked position, so that the locking portion 21 of the locking member 2 can abut against the limiting portion 202 of the network cable connector 200 to prevent the network cable connector 200 from being pulled out, that is, to prevent the network cable connector 200 inserted into the plug port 11 from being removed from the plug port. 11 is disengaged, thereby locking the network cable connector 200; when the network cable connector 200 needs to be unlocked, the locking member 2 in the network interface device 100 is controlled to move to the unlocking position again, that is, the locking portion 21 of the locking member 2 no longer restricts the plugging of the network cable connector 200, and the network cable connector 200 can be smoothly pulled out from the plug-in port 11. In this way, the locking member 2 is integrated in the network interface device 100 to realize the locking and unlocking of the ordinary network cable connector 200, and the locking method is suitable for various ordinary network cable connectors 200, that is, the locking of the ordinary network cable connector 200 and the network interface device 100 is satisfied, thereby improving the safety protection level of the connection between the ordinary network cable connector 200 and the network interface device 100.

[0086] Furthermore, when the network interface device 100 is not needed to connect to the network, the locking member 2 in the network interface device 100 can also be controlled to move to the locking position, so that the network cable connector 200 to be inserted is blocked by the locking portion 21, preventing the unauthorized network cable connector 200 from being inserted into the plug port 11, which is beneficial to improving data security and also realizes the active protection function of the network interface device 100.

[0087] Furthermore, in some embodiments of the present application, the network interface device 100 is further provided with a limiting member 3, wherein the limiting member 3 is used to limit the locking member 2 when the locking member 2 moves to the locking position, and the limiting methods include but are not limited to abutment limiting, clamping limiting, etc. For example, the limiting member 3 can be constructed as a latch, and when the locking member 2 moves to the locking position, the latch can be plugged with the locking member 2, thereby limiting the movement of the locking member 2. Such a configuration is conducive to further improving the locking performance of the locking member 2 in the locking position, thereby further improving the safety protection level of the network interface device 100. It should be noted that when the locking member 2 needs to be moved from the locking position to the unlocking position, it is necessary to first stop the limiting function of the limiting member 3 on the locking member 2 so that the locking member 2 can move normally.

[0088] According to the network interface device 100 of the first aspect embodiment of the present application, the network interface device 100 has an internally integrated locking member 2 and a limiting member 3. When the locking member 2 moves to the unlocked position, the network cable connector 200 can be directly inserted into the plug port 11 to achieve the connection between the network interface device 100 and the network cable connector 200. Then, the locking member 2 is moved to the locked position. The locking member 2 can prevent the network cable connector 200 inserted into the plug port 11 from detaching from the plug port 11, thereby locking the network cable connector 200. When the network cable connector 200 needs to be unlocked, the locking member 2 is moved back to the unlocked position to pull the network cable connector 200 out of the plug port 11. This locking method The invention is applicable to various common network cable connectors 200, that is, it can lock the common network cable connector 200 with the network interface device 100, thereby improving the safety protection level of the connection between the common network cable connector 200 and the network interface device 100, and when the network cable connector 200 is not plugged into the plug port 11, the locking member 2 can be moved to the locking position to prevent the network cable connector 200 from being inserted into the plug port 11, thereby realizing the active protection function of the network interface device 100, and at the same time, when the locking member 2 moves to the locking position, the limiting member 3 can also limit the locking member 2 when the locking member 2 moves to the locking position, thereby further improving the locking performance of the locking member 2 in the locking position, and further improving the safety protection level.

[0089] In some embodiments of the present application, Figure 1-Figure 5 As shown, the network interface device 100 also includes: a mounting bracket 4 and a first driving member 5, the mounting bracket 4 is fixed in the shell, the locking member 2 is movably arranged on the mounting bracket 4, the first driving member 5 is arranged on the mounting bracket 4, the first driving member 5 can be a driving motor, a driving cylinder, or a driving hydraulic, etc., the first driving member 5 can be directly connected to the locking member 2 by transmission, and can also be indirectly connected by transmission, and the transmission method includes but is not limited to screw transmission, telescopic transmission, rotation transmission, etc. The first driving member 5 is electrically connected to the driving chip of the inner board of the network interface device 100, and the first driving member 5 is controlled by the driving chip to drive the locking member 2 to move to the unlocking position or the locking position, wherein the driving chip can be independent or integrated on the network interface device 100.

[0090] Specifically, taking the avoidance hole 12 set on the top wall of the network interface body 1 as an example, the first driving member 5 is used to drive the locking member 2 to move up and down, so that the locking portion 21 of the locking member 2 can selectively extend into the plug-in port 11 or move out of the plug-in port 11 through the avoidance hole 12, thereby moving the locking member 2 to the unlocking position or the locking position. For example, assuming that the locking member 2 is initially in the locking position, the first driving member 5 drives the locking member 2 to move upward, so that the locking portion 21 of the locking member 2 moves out of the plug-in port 11 to reach the unlocking position. When the locking member 2 is required to lock the network cable connector 200 again or prevent the external network cable connector 200 from being inserted, the first driving member 5 drives the locking member 2 to move downward, so that the locking portion 21 of the locking member 2 extends into the plug-in port 11 to reach the locking position. With this arrangement, automatic control of the locking member 2 is realized, which is beneficial to improving the automation level of the network interface device 100.

[0091] In some embodiments of the present application, Figure 1-Figure 5 As shown, the network interface device 100 also includes: a first elastic member 6, the mounting bracket 4 is provided with a guide hole 41, the locking member 2 has a guide rod 22 arranged corresponding to the guide hole 41, the guide rod 22 is passed through the guide hole 41 and is movable relative to the guide hole 41, and the first elastic member 6 is sleeved on the guide rod 22 and installed between the mounting bracket 4 and the locking member 2.

[0092] Specifically, the avoidance hole 12 is set on the top wall of the network interface body 1 as an example. Figure 2 and Figure 3 As shown, the mounting bracket 4 includes a first mounting plate 42, the locking member 2 is arranged below the first mounting plate 42, the locking portion 21 of the locking member 2 is opposite to the avoidance hole 12, when the locking member 2 moves up and down, the locking portion 21 of the locking member 2 can extend into the plug-in port 11 through the avoidance hole 12 or move out of the plug-in port 11, further, a guide rod 22 is provided above the locking member 2, the first mounting plate 42 is provided with a guide hole 41 corresponding to the guide plate, the guide rod 22 is penetrated in the guide hole 41, and the guide rod 22 can move along the axial direction of the guide hole 41, it can be understood that the number of the guide rods 22 can be multiple, such as Figure 7-Figure 9 As shown, the locking member 2 is provided with three guide rods 22. Thus, the guiding cooperation between the guide rods 22 and the guide holes 41 is helpful to improve the stability of the locking member 2 during movement, and avoid the locking member 2 from being offset when moving up and down, thereby causing the locking portion 21 to collide with the avoidance hole 12.

[0093] Furthermore, the network interface device 100 is also provided with a first elastic member 6 between the mounting bracket 4 and the locking member 2. The first elastic member 6 can be constructed as a spring, and the spring is sleeved on the guide rod 22 of the locking member 2. For example, assuming that the locking member 2 is initially in the locking position, the locking member 2 is driven to move upward by the first driving member 5, so that the locking portion 21 of the locking member 2 moves out of the plug port 11 to reach the unlocking position. During this process, the locking member 2 compresses the spring, and the spring accumulates elastic force. When the locking member 2 is required to lock the network cable connector 200 again or prevent the external network cable connector 200 from being inserted, when the first driving member 5 is not working or the power is off, the spring's own elastic force can be used to drive the locking member 2 to move downward and return to its original position, so that the locking portion 21 of the locking member 2 extends into the plug port 11 to reach the locking position. In this way, the locking member 2 can be moved back and forth between the unlocking position and the locking position through the coordinated use of the first driving member 5 and the first elastic member 6, which satisfies the automatic control function and is conducive to cost saving.

[0094] In some embodiments of the present application, Figure 2 , Figure 3 and Figure 5 As shown, the first driving member 5 includes a first driving part 51 and a first driving body 52. ​​The first driving body 52 is fixed to the mounting bracket 4. The locking member 2 is also provided with a transmission part 23 assembled with the first driving part 51. The first driving body 52 is suitable for driving the first driving part 51 to extend and retract, so that the first driving part 51 drives the transmission part 23 to drive the locking member 2 to move to the unlocking position or the locking position.

[0095] Specifically, if Figure 2 and Figure 3 As shown, the mounting bracket 4 also includes a second mounting plate 43, the first driving body 52 is fixedly mounted on the second mounting plate 43, the first driving portion 51 is transmission-connected to the first driving body 52, the first driving body 52 can be constructed as a telescopic motor, a servo motor, an electromagnet, etc., the first driving body 52 can drive the first driving portion 51 to telescopically move, further, as Figure 3 As shown, the first driving part 51 is assembled with the transmission part 23 of the locking member 2. The first driving part 51 has a driving inclined surface, and the transmission part 23 is assembled in abutment with the driving inclined surface. The first driving part 51 drives the transmission part 23 through the driving inclined surface to drive the locking member 2 to move to the unlocking position or the locking position.

[0096] Further, as a specific example, Figure 3As shown, continuing to use the avoidance hole 12 set on the top wall of the network interface body 1 as an example for explanation, when the first driving body 52 drives the first driving part 51 to extend outward, the driving inclined surface of the first driving part 51 drives the transmission part 23 to move upward, so that the transmission part 23 drives the locking member 2 to move upward until it moves to the unlocking position, and when the first driving body 52 drives the first driving part 51 to retract inward, the locking member 2 moves downward and returns to its original position under its own gravity and the elastic action of the first elastic member 6, so that the locking part 21 of the locking member 2 extends into the plug-in port 11 to reach the locking position. With this arrangement, the locking member 2 can be moved back and forth between the unlocking position and the locking position through the coordinated use of the first driving part 51, the first driving body 52, and the first elastic member 6, thereby simplifying the structure of the first driving member 5, and the structure is simple and reliable.

[0097] In some embodiments of the present application, Figure 5 As shown, the first driving member 5 also includes a second elastic member 53 , the first driving portion 51 has a first limiting end surface 511 arranged opposite to the first driving body 52 , and the second elastic member 53 is arranged on the first driving portion 51 and installed between the first limiting end surface 511 and the first driving body 52 .

[0098] Specifically, the first driving member 5 is further provided with a second elastic member 53 between the first limiting end surface 511 of the first driving portion 51 and the first driving body 52. ​​The second elastic member 53 can be constructed as a spring, and the spring is arranged on the first driving portion 51. For example, the first driving body 52 is constructed as an electromagnet as an example for explanation. When the first driving body 52 is energized, the first driving body 52 drives the first driving portion 51 to retract inward, and the locking member 2 moves downward under its own gravity and the elastic action of the first elastic member 6 and returns to its original position, so that the locking portion 21 of the locking member 2 extends into the plug port 11 to reach the lock. The locking member 2 is locked in place when the first drive body 52 is in a locked state, and the locking member 2 is locked in place when the first drive body 52 is locked.

[0099] In some embodiments of the present application, Figure 2 , Figure 3 and Figure 5As shown, the network interface device 100 also includes: a second driving member 7, the second driving member 7 includes a second driving part 71 and a second driving body 72, the second driving body 72 is fixed to the mounting bracket 4, the first driving part 51 has a first limiting groove 512 arranged opposite to the second driving part 71, and the second driving body 72 is suitable for driving the second driving part 71 to move so that the second driving part 71 is limitedly assembled or separated from the first limiting groove 512.

[0100] Specifically, if Figure 2 and Figure 3 As shown, the second driving body 72 is fixedly mounted on the first mounting plate 42 of the mounting bracket 4, the first driving part 51 is provided with a first limiting groove 512, and the first limiting groove 512 is arranged opposite to the second driving part 71 of the second driving member 7, and the second driving body 72 is used to drive the second driving part 71 to move, such as telescopic movement, rotation, etc., so that the second driving part 71 can be limitedly assembled or separated from the first limiting groove 512. As a specific example, the second driving body 72 is used to drive the second driving part 71 to extend and retract. When the second driving part 71 drives the second driving part 71 to extend, the second driving part 71 can be limitedly assembled with the first limiting groove 512, and when the second driving body 72 drives the second driving part 71 to retract, the second driving part 71 can be separated from the first limiting groove 512.

[0101] It can be understood that when the second driving part 71 is limitedly assembled with the first limiting groove 512, the second driving part 71 can block the movement of the first driving part 51. When the second driving part 71 is separated from the first limiting groove 512, the second driving part 71 no longer limits the first driving part 51, and the first driving part 51 can drive the movement of the locking member 2.

[0102] Further, as a specific example, Figure 3As shown, the avoidance hole 12 is set on the top wall of the network interface body 1 as an example for explanation. It is assumed that the initial state is that the second driving part 71 is limitedly assembled with the first limiting groove 512. When it is necessary to drive the locking member 2 to move to the unlocking position, the second driving body 72 drives the second driving part 71 to separate from the first limiting groove 512, and the first driving body 52 drives the first driving part 51 to extend outward, and the driving inclined surface of the first driving part 51 drives the transmission part 23 to move upward, so that the transmission part 23 drives the locking member 2 to move upward until it moves to the unlocking position. When it is necessary to drive the locking member 2 to move to the locking position, the first driving body 52 drives the second driving part 71 to separate from the first limiting groove 512, and the first driving body 52 drives the first driving part 51 to extend outward. The driving inclined surface of the first driving part 51 drives the transmission part 23 to move upward, so that the transmission part 23 drives the locking member 2 to move upward until it moves to the unlocking position. A driving part 51 retracts inward, and the locking member 2 moves downward and returns to its original position under its own gravity and the elastic action of the first elastic member 6, so that the locking part 21 of the locking member 2 extends into the plug-in port 11 to reach the locking position, and then the second driving body 72 is controlled to drive the second driving part 71 and the first limiting groove 512 to be limited and assembled, so that the first driving member 5 is restricted to the locking position corresponding to the locking member 2. In this way, the abutment and limitation of the second driving part 71 and the first limiting groove 512 can further improve the locking performance of the locking member 2 in the locking position, thereby further improving the safety protection level of the network interface device 100.

[0103] In some embodiments of the present application, Figure 5 As shown, the second driving member 7 also includes a third elastic member 73. The second driving portion 71 has a second limiting end surface 711 arranged opposite to the second driving body 72. The third elastic member 73 is arranged on the second driving portion 71 and installed between the second limiting end surface 711 and the second driving body 72.

[0104] Specifically, the second driving member 7 is further provided with a third elastic member 73 between the second limiting end surface 711 of the second driving portion 71 and the second driving body 72. The first elastic member 6 can be constructed as a spring, which is provided on the second driving portion 71. For example, Figure 5 As shown, taking the second driving body 72 constructed as an electromagnet as an example for explanation, when the second driving body 72 is energized, the second driving body 72 drives the second driving part 71 to retract, and the second driving part 71 is separated from the first limiting groove 512, and the third elastic member 73 is continuously compressed during the retraction of the second driving part 71. The third elastic member 73 accumulates elastic force under the compression of the second driving part 71. When the locking member 2 reaches the locking position, the second driving body 72 is powered off, and the second driving part 71 extends outward under the action of the third elastic member 73 to drive the second driving part 71 to be limitedly assembled with the first limiting groove 512, so that the first driving member 5 is restricted to the locking position corresponding to the locking member 2. In this way, by setting the third elastic member 73, it is easy to realize the resetting of the second driving member 7. The use of the second driving body 72 not only meets the use requirements of the second driving member 7, but also simplifies the structure of the second driving member 7. The structure is simple and reliable.

[0105] Further, in order to enable those skilled in the art to better understand the present solution, the operation mode of the network interface device 100 is described in detail below by way of example, and the avoidance hole 12 is set on the top wall of the network interface body 1 as an example for description. At the same time, the first driving body 52 and the second driving body 72 are both constructed as electromagnets. Assuming that the initial state is that the locking member 2 is in the locking position, and the second elastic member 53 is in a compressed state, when the locking member 2 needs to be moved from the locking position to the unlocking position, the control limit member 3 stops the limiting function of the locking member 2, and at the same time When the second driving body 72 is energized, the second driving portion 71 is driven to separate from the first limiting groove 512, and the third elastic member 73 is continuously compressed during the retraction of the second driving portion 71. The third elastic member 73 accumulates elastic force under the compression of the second driving portion 71. Then, the first driving body 52 is controlled to be de-energized, and the first driving portion 51 is extended outward under the action of the second elastic member 53. The driving inclined surface of the first driving portion 51 drives the transmission portion 23 to move upward, so that the transmission portion 23 drives the locking member 2 to move upward until it moves to the unlocking position. In this process, the lock The tightening member 2 compresses the first elastic member 6, and the first elastic member 6 accumulates elastic force. When the locking member 2 needs to lock the network cable connector 200 again or prevent the external network cable connector 200 from being inserted, the first driving body 52 is controlled to be energized, and the first driving body 52 drives the first driving part 51 to retract inward. The locking member 2 moves downward under its own gravity and the elastic action of the first elastic member 6 and returns to its original position, so that the locking part 21 of the locking member 2 extends into the plug port 11 to reach the locking position. In this process, the first driving part 51 compresses the second elastic member 53, and the first driving part 51 compresses the second elastic member 53. The second elastic member 53 is in a compressed state and accumulates elastic force. When the locking member 2 reaches the locking position, the second driving body 72 is powered off, and the second driving part 71 extends outward under the action of the third elastic member 73 to drive the second driving part 71 to be limitedly assembled with the first limiting groove 512, so that the first driving member 5 is limited to the locking position corresponding to the locking member 2. In this way, the automatic control of the locking member 2 is realized through the mutual cooperation of various parts, which is beneficial to improving the automation level of the network interface device 100, and the structure is simple and reliable, and the cost is low.

[0106] In some embodiments of the present application, Figure 1 , Figure 7-Figure 9 As shown, the locking portion 21 is provided with a second limiting groove 211 which cooperates with the limiting member 3 . When in the locking position, the limiting member 3 is suitable for being inserted into the second limiting groove 211 to limit the locking member 2 in the locking position.

[0107] Specifically, if Figure 7As shown, when the external network cable connector 200 is inserted into the plug port 11, the locking member 2 is controlled to move to the locking position so that the locking portion 21 of the locking member 2 and the limiting portion 202 of the network cable connector 200 are abutted and assembled with each other, thereby preventing the network cable connector 200 from being pulled out, and when the locking member 2 moves to the locking position, the limiting member 3 is driven to insert into the second limiting groove 211, and the driving method includes but is not limited to motor drive, etc., wherein the extension direction of the second limiting groove 211 is perpendicular to the up and down movement direction of the locking member 2. In this way, when the limiting member 3 is inserted into the second limiting groove 211, the limiting member 3 can limit the up and down movement of the locking portion 21, that is, limit the up and down movement of the locking member 2, thereby limiting the locking member 2 in the locking position, which is beneficial to further improve the locking performance of the locking member 2 in the locking position, and the limiting method is simple, reliable and low-cost.

[0108] In some embodiments of the present application, Figure 2 , Figure 3 , Figure 5 , Figure 7-Figure 9 As shown, the transmission part 23 is provided with a limiting hole 231 which is assembled with the limiting member 3. When in the locking position, the limiting member 3 is suitable for being inserted into the limiting hole 231 to limit the locking member 2 in the locking position.

[0109] That is to say, a corresponding limiting hole 231 can also be provided on the transmission part 23 of the locking member 2, such as Figure 7 As shown, when the external network cable connector 200 is inserted into the plug port 11, the locking piece 2 is controlled to move to the locking position. When the locking piece 2 moves to the locking position, the limit piece 3 is driven to insert into the limit hole 231. The driving method includes but is not limited to motor drive, wherein the axial direction of the limit hole 231 is perpendicular to the up and down movement direction of the locking piece 2. With such a configuration, when the limit piece 3 is inserted into the limit hole 231, the limit piece 3 can limit the up and down movement of the transmission part 23, that is, limit the up and down movement of the locking piece 2, thereby limiting the locking piece 2 in the locking position, which is beneficial to further improve the locking performance of the locking piece 2 in the locking position, and the limiting method is simple, reliable and low-cost.

[0110] Of course, limiting structures may also be provided at other positions of the locking member 2, which will not be described one by one with examples here.

[0111] In order to further improve the security protection level of the network interface device 100, the present application also provides a security protection method for a network interface device 100 based on the network interface device 100, wherein the network interface device 100 is the network interface device 100 in the above-mentioned first aspect embodiment.

[0112] The security protection method for the network interface device proposed in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0113] Fig.11FIG. 1 is a flow chart of a security protection method for a network interface device according to the first embodiment of the present application. Fig.11 As shown, the security protection method of the network interface device includes:

[0114] S101, supplying power to the network interface device and detecting whether the function of the plug-in port is normal.

[0115] Specifically, in the initial stage of powering the network interface device 100, the network cable connector 200 is not plugged into the plug port 11 of the network interface device 100. First, it is necessary to detect whether the function of the plug port 11 is normal. Furthermore, if the network interface device 100 includes multiple network interface bodies 1, the network interface device 100 will detect the plug port 11 corresponding to each network interface body 1, and will also number each network interface body 1 to implement the detection of the status of each plug port 11.

[0116] S102, after detecting that the plug port functions normally, controlling the locking member to move to a locking position to physically lock the plug port.

[0117] Specifically, when it is detected that the plug-in port 11 of the corresponding network interface body 1 is functioning normally, the network interface device 100 will control the locking piece 2 corresponding to the network interface body 1 to move to the locking position, so as to realize the physical locking of the plug-in port 11 in the network interface body 1 by the locking piece 2, that is, before plugging the network cable connector 200 into the plug-in port 11, the plug-in port 11 with normal function is locked by default, and the plug-in port 11 is in a disabled state, so that the network cable connector 200 to be inserted can be blocked, and the unauthorized network cable connector 200 can be prevented from being inserted into the plug-in port 11, which is beneficial to improving data security and also realizes the active protection function of the network interface device 100.

[0118] According to the security protection method of the network interface device of the second aspect of the present application, the plug port 11 can be physically locked before the network cable connector 200 is inserted into the plug port 11, and an unauthorized network cable connector 200 can be prevented from being inserted into the plug port 11, which is beneficial to improving data security and realizing the active protection function of the network interface device 100.

[0119] In some embodiments of the present application, the method further includes: after controlling the locking member to move to the locking position, controlling the limiting member to limit the locking member to the locking position.

[0120] Specifically, the network interface device 100 is also provided with a limit member 3, wherein the limit member 3 is used to limit the locking member 2 when the locking member 2 moves to the locking position, and the limiting methods include but are not limited to abutment limiting, card limiting, etc. Such a setting can improve the locking performance of the locking member 2 when it is in the locking position, and before the network cable connector 200 is plugged into the plug port 11, the limit member 3 can further improve the active protection function of the network interface device 100.

[0121] In some embodiments of the present application, the method further includes: in response to an authorization signal for inserting a network cable connector, controlling the limiting member to stop limiting the locking member, and controlling the locking member to move to an unlocked position until the network cable connector is detected to be inserted into the plug port.

[0122] Specifically, when the network interface device 100 needs to use one or more plug-in ports 11, it is necessary to first obtain an authorization signal for inserting the network cable connector 200. For example, the authorization signal can be sent to the network interface device 100 through a host, a handheld PDA, a mobile phone, or other device. When the network interface device 100 receives the authorization signal for inserting the network cable connector 200, the network interface device 100 controls the movement of the limit member 3 in the corresponding network interface body 1 according to the authorization signal, so that the limit member 3 stops limiting the locking member 2, and then controls the locking member 2 to move to the unlocked position until the network cable connector 200 is detected to be inserted into the plug-in port 11. In this way, the network cable connector 200 can be inserted only after receiving the authorization signal, which is beneficial to improving safety performance. It should be noted that if the network cable connector 200 is not detected to be inserted into the plug port 11 within the authorized time, the locking member 2 will be controlled to move to the locking position again and the limiting member 3 will be controlled to limit the locking member 2 to the locking position, that is, the active defense function of the network interface device 100 will be restored, thereby avoiding the failure of the active defense caused by the network cable connector 200 not being inserted for a long time.

[0123] In some embodiments of the present application, the method further includes: when it is detected that a network cable connector is inserted into the plug port, controlling the locking member to move to a locking position, and controlling the limiting member to limit the locking member to the locking position.

[0124] Specifically, when the authorized plug port 11 detects that the network cable connector 200 has been inserted, the locking member 2 is controlled to move to the locking position, and the limiting member 3 is controlled to limit the locking member 2 to the locking position, thereby realizing the locking and insurance functions of the network cable connector 200. It should be noted that the network interface device 100 will also record and number the network interface body 1 that has been inserted into the network cable connector 200, and detect data transmission in real time. If abnormal data transmission is detected or someone violently damages the plug port 11, the network connection function can also be disabled at the data level, thereby achieving dual physical and data protection.

[0125] In some embodiments of the present application, the method also includes: when it is detected that the network cable connector of the plug port is unplugged, obtaining a first time length when the network cable connector is not inserted into the plug port, if the first time length is less than a preset time length, the limit member maintains an unlimited state of the locking member, and the locking member remains in an unlocked position, if the first time length is greater than the preset time length, controlling the locking member to move to the locked position, and controlling the limit member to limit the locking member to the locked position.

[0126] Specifically, when the network cable connector 200 needs to be replaced, the network interface device 100 responds to the authorization signal for unplugging the network cable connector 200, controls the limiting member 3 to stop limiting the locking member 2, controls the locking member 2 to move to the unlocked position, and unplugs the current network cable connector 200 from the plug port 11. When the network interface device 100 detects that the network cable connector 200 of the plug port 11 is unplugged, the network interface device 100 starts timing to record the first time length that the plug port 11 is not plugged into the network cable connector 200. When the first time length is less than the preset time length, the limiting member 3 maintains the unlimited state of the locking member 2, and the locking member 2 remains in the unlocked position, that is, the network cable connector 200 can be replaced within the preset time length. The network cable connector 200 is replaced, and after the network cable connector 200 is replaced, the locking member 2 is controlled to move to the locking position, and the limiting member 3 is controlled to limit the locking member 2 in the locking position; if the first time length is greater than the preset time length, the locking member 2 is controlled to move to the locking position, and the limiting member 3 is controlled to limit the locking member 2 in the locking position, that is, if the network cable connector 200 to be replaced is not detected to be inserted into the plug-in port 11 within the preset time, the locking member 2 will be controlled to move to the locking position again and the limiting member 3 will be controlled to limit the locking member 2 in the locking position, that is, the active defense function of the network interface device 100 is restored, thereby avoiding the failure of the active defense caused by the failure to replace the network cable connector 200 for a long time.

[0127] It should be noted that, when the network cable connector 200 needs to be unplugged and the plug port 11 is disabled, the network interface device 100 responds to the authorization signal for unplugging the network cable connector 200, controls the limit member 3 to stop limiting the locking member 2, and controls the locking member 2 to move to the unlocking position to unplug the current network cable connector 200 from the plug port 11. When the network interface device 100 detects that the network cable connector 200 of the plug port 11 is unplugged, it controls the locking member 2 to move to the locking position again and controls the limit member 3 to limit the locking member 2 to the locking position, thereby restoring the active defense function of the network interface device 100.

[0128] When it is necessary to test each plug port 11, the software side selects the test mode, keeps all or specified plug ports 11 unlocked within the authorized time, and turns off the automatic locking action. The logic of the software side in this process is network opening → network monitoring → test end (manual operation) → active defense state (default state), determines to keep the unlocked state until the test ends, and then returns to the active defense state.

[0129] Further, in order to enable those skilled in the art to better understand the present invention, Fig.12a and Figure 12b As shown, the following is an overall description of the workflow of this solution.

[0130] Fig.12a This is a flowchart of the first part of the security protection method for a network interface device according to the second embodiment of the present application. Figure 12b FIG. 2 is a flow chart of the second part of the security protection method for a network interface device according to the second embodiment of the present application. Fig.12a and Figure 12b As shown, the security protection method of the network interface device includes:

[0131] S201, whether the plug port self-check function is normal. Specifically, in the initial stage of powering the network interface device 100, the network cable connector 200 is not plugged into the plug port 11 of the network interface device 100, and first it is necessary to check whether the function of the plug port 11 is normal. If it is normal, it proceeds to step S202, if not, it proceeds to step S203.

[0132] S202, enter the test mode, the plug port is opened: the limit member is controlled to stop limiting the locking member, and the locking member is controlled to move to the unlocking position. That is, when the self-test function of the plug port 11 is normal, the test mode is entered, and the plug port 11 is controlled to be opened.

[0133] S203, the system prompts an alarm.

[0134] S204, whether the communication of the plug port is normal. Specifically, during the test process, whether the communication of the plug port 11 is normal is detected, if normal, the process proceeds to step S205, if abnormal, the process proceeds to step S206.

[0135] S205, the test ends.

[0136] S206, the system prompts an alarm and replaces the equipment.

[0137] S207, control the locking member to move to the locking position. After the test is completed, first control the locking member 2 to move to the locking position.

[0138] S208, the control limiter limits the locking member to the locking position, and the plug port enters the locked state. That is, when the locking member 2 moves to the locking position, the control limiter 3 limits the locking member 2 to the locking position, and the plug port 11 enters the locked state. At this time, the network interface device 100 has an active protection function.

[0139] S209, whether the authorization signal for inserting the network cable connector is received. Specifically, when the network interface device 100 needs to use one or more plug-in ports 11, it needs to first obtain the authorization signal for inserting the network cable connector 200. For example, the authorization signal can be sent to the network interface device 100 by a host, a handheld PDA, a mobile phone, etc. When the network interface device 100 receives the authorization signal for inserting the network cable connector 200, it proceeds to step S210. If the authorization signal is not received, it proceeds to step S211.

[0140] S210, control the limiter to stop limiting the locking member, control the locking member to move to the unlocked position, and the plug port is opened to enter the unlocked state. That is, when the network interface device 100 receives the authorization signal for inserting the network cable connector 200, the network interface device 100 controls the limiter 3 in the corresponding network interface body 1 to move according to the authorization signal, so that the limiter 3 stops limiting the locking member 2, and then controls the locking member 2 to move to the unlocked position.

[0141] S211, the docking port remains locked.

[0142] S212, whether the network cable connector is inserted into the plug port. When it is detected that the network cable connector 200 is inserted into the plug port 11, the process proceeds to step S213, and when it is detected that the network cable connector 200 is not inserted into the plug port 11, the process proceeds to step S214.

[0143] S213, control the locking member to move to the locking position, control the limiting member to limit the locking member in the locking position, and the plug port enters a locked state. When the authorized plug port 11 detects that the network cable connector 200 has been inserted, control the locking member 2 to move to the locking position, and control the limiting member 3 to limit the locking member 2 in the locking position, thereby achieving the locking and insurance functions of the network cable connector 200.

[0144] S214, whether the time period when the network cable connector is not plugged into the plug port is greater than the first authorized time period. Determine whether the time period when the network cable connector is not plugged into the plug port is greater than the first authorized time period. If it is greater than the first authorized time period, return to step 207; if it is less than the first authorized time period, proceed to step 215.

[0145] S215, the docking port remains unlocked.

[0146] S216, whether the network cable connector unplugging authorization signal is received. When the network cable connector 200 needs to be replaced, the network interface device 100 responds to the authorization signal to unplug the network cable connector 200. If the network cable connector 200 unplugging authorization signal is received, the process proceeds to step 217. If the network cable connector 200 unplugging authorization signal is not received, the process proceeds to step 211.

[0147] S217, the limiting member is controlled to stop limiting the locking member, the locking member is controlled to move to the unlocked position, the plug port is opened, and the unlocked state is entered. Specifically, in response to the authorization signal for unplugging the network cable connector 200, the network interface device 100 controls the limiting member 3 to stop limiting the locking member 2, and controls the locking member 2 to move to the unlocked position.

[0148] S218, detecting whether the network cable connector is unplugged from the plug port. If the network cable connector 200 is unplugged from the plug port 11, then proceed to step 219; if the network cable connector 200 is not unplugged from the plug port 11, then proceed to step 222.

[0149] S219, whether the plug-in port is disabled. If the plug-in port of the network interface device 100 is disabled, the process proceeds to step 207; if the plug-in port of the network interface device 100 is not disabled, the process proceeds to step 220.

[0150] S220, obtaining a first duration of time when the plug port is not plugged into the network cable connector. When the network interface device 100 detects that the network cable connector 200 of the plug port 11 is unplugged, the network interface device 100 starts timing to record the first duration of time when the plug port 11 is not plugged into the network cable connector 200.

[0151] S221, whether the first time length is greater than the preset time length. If the first time length is less than the preset time length, the process proceeds to step S215, the limiting member 3 remains in the unlimited state of the locking member 2, and the locking member 2 remains in the unlocked position; if the first time length is greater than the preset time length, the process proceeds to step 207.

[0152] S222, obtaining a second time length during which the network cable connector is not unplugged. If the network cable connector is not unplugged from the plug port, obtaining a second time length during which the network cable connector 200 is not unplugged.

[0153] S223, whether the second duration is greater than the second authorized duration. If the second duration is greater than the second authorized duration, proceed to step S207; if the second duration is less than the second authorized duration, proceed to step S215.

[0154] In summary, according to the security protection method of the network interface device of the second embodiment of the present application, the plug port 11 can be physically locked before the network cable connector 200 is inserted into the plug port 11, and the unauthorized network cable connector 200 can be prevented from being inserted into the plug port 11, which is beneficial to improving data security and realizing the active protection function of the network interface device 100; at the same time, the network cable connector 200 can only be inserted after receiving the authorization signal, which is beneficial to improving security performance. It should be noted that if the network cable connector 200 is not detected to be inserted into the plug port 11 within the authorization time, the locking member 2 will be re-controlled to move to the locking position and the limiting member 3 will be controlled to limit the locking member 2 to the locking position, that is, the active defense function of the network interface device 100 is restored, thereby avoiding the failure of active defense caused by the failure to insert the network cable connector 200 for a long time.
