Description

Technical Field

[0001] This application relates to the field of network terminals, and in particular to a network security device with a connector anti-detachment structure. Background Technology

[0002] Network security devices such as data exchange machines typically have multiple interfaces on their casings for various connectors to connect to. In related technologies, to prevent connectors from detaching from the interfaces, some connectors are designed with anti-detachment structures. For example, RJ45 connectors (commonly known as crystal heads) have a locking mechanism that automatically locks in place after the connector is inserted into the device's interface. Alternatively, some connectors have built-in bolts, and corresponding screw holes are provided at the device's interface for the bolts to be screwed in. After the connector is inserted into the interface, tightening the bolts locks the connector in place to prevent it from detaching from the interface.

[0003] However, some connectors in related technologies still lack anti-detachment designs, such as some round connectors or USB cable connectors. When these connectors are pulled after being inserted into the device's interface, they are prone to detaching from the device's interface. How to prevent such connectors from detaching from the device's interface has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide a network security device with a connector anti-detachment structure.

[0005] To achieve the above objectives, this application provides the following technical solution.

[0006] A network security device with a connector anti-detachment structure includes a housing with an interface for inserting a connector in a first direction. The device also includes an anti-detachment structure comprising a base and a locking member. The base is mounted on the housing, and the locking member includes a locking portion disposed on the base. The locking portion is rotatable relative to the base between a stop position and a clearance position. In the stop position, the locking portion is at least partially located on the tail side of the connector to prevent the connector from detaching from the interface in a second direction, which is opposite to the first direction. In the clearance position, the locking portion moves away from the opposite side of the interface to allow the connector to enter / exit the interface.

[0007] Compared with existing technologies, the advantages of this solution are:

[0008] In this solution, the locking part of the locking component is designed to move between the stop position and the avoidance position. In this way, after the connector is inserted into the interface, the locking part can be flipped to the stop position. At this time, the locking part will be on the tail side of the connector, thereby restricting the connector from being pulled out of the interface in the second direction (i.e. the direction of connector pull-out), thus achieving the anti-detachment of the connector.

[0009] When it is necessary to insert or remove the connector from the interface, the locking part can be flipped to the avoidance position to prevent the locking part from obstructing the connector from entering or leaving the interface.

[0010] As an optional embodiment of this application, the locking part can also be adjusted along a first linear direction, and the locking part can be locked after adjustment.

[0011] As an optional embodiment of this application, the anti-detachment structure further includes a slide block, which is slidably disposed on the base along a first linear direction; the locking member is hinged to the slide block so that the locking part can move between a stop position and a clearance position.

[0012] As an optional embodiment of this application, the base includes at least one side plate portion located on the side of the locking member. The side plate portion is provided with a plurality of slots that are sequentially spaced along a first straight direction. The locking member is provided with a protrusion that can be engaged in the slot. When the protrusion is engaged in the slot, the locking member is locked in the first straight direction.

[0013] As an optional embodiment of this application, an elastic element is provided between the locking member and the slide block, the elastic element being used to provide an elastic force to drive the locking part to have a tendency to flip towards the stop position.

[0014] As an optional embodiment of this application, the anti-detachment structure further includes a limiting member disposed on the base, which is used to block the slide to prevent the slide from sliding out of the base in the second direction.

[0015] As an optional embodiment of this application, the limiting member is detachably mounted on the base.

[0016] As an optional embodiment of this application, one of the sidewalls of the slide and the base is provided with a groove extending along a first straight direction, and the other is provided with a protruding rib extending along the first straight direction. The protruding rib slides in the groove along the first straight direction.

[0017] As an optional embodiment of this application, the end of the locking member is bent toward the base to form a locking portion.

[0018] As an optional embodiment of this application, the locking part is provided with a clearance opening for the wire of the connector, and the clearance opening is provided facing one end of the connector.

[0019] Other advantages and effects of this application are explained in detail in the Detailed Description and Drawings sections.

[0036] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Reference Figure 1-5 As shown, this embodiment provides a network security device (hereinafter referred to as the device) with a connector anti-detachment structure 2, mainly targeting connectors that do not have an anti-detachment function, such as... Figure 1 As shown, this embodiment uses round connector J1 and USB connector J2 as examples for explanation.

[0038] like Figure 1 As shown, the embodiment provided includes a housing 1, which is provided with an interface 11 for inserting a connector in a first direction. In addition, for ease of explanation, the direction opposite to the first direction is referred to as the second direction. In this case, the first direction can be understood as the insertion direction of the connector, and the second direction can be understood as the removal direction of the connector. Both the first direction and the second direction are in the first straight line direction.

[0039] like Figure 1 As shown, there may be one or more interfaces 11. In some embodiments, multiple interfaces 11 are arranged at intervals along the width direction of the housing 1, and one interface 11 corresponds to one type of connector.

[0040] In addition, in this embodiment, the device also includes an anti-detachment structure 2. The number of anti-detachment structures 2 corresponds to the number of interfaces 11. Generally, one interface 11 corresponds to one anti-detachment structure 2. The structures of each anti-detachment structure 2 are basically the same. Therefore, in this embodiment, one of them is used as an example for specific explanation.

[0041] like Figure 1 and Figure 3 As shown, the anti-detachment structure 2 includes a base 21 and a locking member 22. The base 21 is installed on the housing 1. In some embodiments, the base 21 is basically U-shaped and mainly includes a bottom plate 212 and side plate portions 211 provided on both sides of the bottom plate 212.

[0042] In some embodiments, such as Figure 1As shown, a mounting groove 12 is provided on the top wall of the housing 1 for the base 21 to be fully embedded. The base 21 can be fixed in the mounting groove 12 by means of screw connection and / or adhesive.

[0043] The locking member 22 includes a locking portion 221, which in some embodiments, such as Figure 3 As shown, the locking member 22 is generally plate-shaped, with one end bent toward the base 21 to form a locking part 221, making the locking member 22 generally L-shaped.

[0044] The locking member 22 is provided on the base 21, and the locking part 221 can be rotated relative to the base 21 between a stop position and a clearance position.

[0045] In the stop position, such as Figure 2 As shown, the locking part 221 is at least partially located on the tail side of the connector to prevent the connector from disengaging from the interface 11 in the second direction; the tail side of the connector here can be understood as follows:

[0046] Generally speaking, such as Figure 1 As shown, the connector mainly includes an insulated main body part J01. One end of the main body part J01 is provided with a terminal part J02 for insertion into the interface 11, and the other end leads out a wire J03. The diameter of the wire J03 is generally smaller than the diameter of the main body part. At this time, the end of the main body part J01 from which the wire J03 leads out can be understood as the tail side of the connector.

[0047] Based on this, after the connector is inserted into the interface 11, the locking part 221 can be flipped to the stop position. At this time, the locking part 221 will be located at the tail side of the connector to form a block, thereby restricting the connector from being pulled out of the interface 11 in the second direction (i.e. the direction in which the connector is pulled out), thus achieving the purpose of preventing the connector from detaching.

[0048] In some embodiments, such as Figure 3 As shown, in order to prevent the locking part 221 from interfering with the lead wire of the connector, the locking part 221 is provided with a clearance opening 222 to avoid the lead wire of the connector. The clearance opening 222 is set to face one end of the connector. In use, as... Figure 2 As shown, the wire enters the relief port 222 through the opening side of the relief port 222. At this time, the locking part 221 straddles the wire and is located on the tail side of the connector to prevent the connector from detaching.

[0049] It is understandable that the lateral width of the relief opening 222 is greater than the diameter of the wire and less than the diameter or lateral length of the tail side of the connector, so as to ensure that the connector will not pass through the relief opening 222 in the second direction.

[0050] like Figure 1As shown in the anti-detachment structure 2 corresponding to the central round connector J1, in the avoidance position, the locking part 221 moves away from the opposite side of the interface 11 to avoid the connector entering / exiting the interface 11. For example, in this embodiment, the locking part 221 flips upward and flips to the position above the housing 1 to avoid the insertion and removal of the connector.

[0051] When it is necessary to insert or remove the connector from interface 11, please refer to 1 and Figure 5 As shown, the locking part 221 can be flipped to the avoidance position to prevent the presence of the locking part 221 from obstructing the connector from entering or exiting the interface 11.

[0052] Since different connectors have different axial lengths of their main body, in order to accommodate connectors with different axial lengths, in some embodiments, the locking part 221 is designed to be movable and adjustable along a first linear direction, and the locking part 221 can be locked after adjustment; the first linear direction is parallel to the first direction.

[0053] Specifically, such as Figure 3 As shown, the anti-detachment structure 2 also includes a slide 23, which is slidably disposed on the base 21 along the first straight line direction. In some embodiments, the slide 23 is basically U-shaped and is slidably disposed in the base 21 along the first straight line direction.

[0054] In order to enable the slide block 23 to slide only relative to the base 21 along the first straight direction, one of the side walls of the slide block 23 and the side wall of the base 21 is provided with a groove 214 extending along the first straight direction, and the other is provided with a rib 231 extending along the first straight direction. The rib 231 slides and engages in the groove 214 along the first straight direction.

[0055] In this embodiment, the specific example shown is as follows: Figure 3 and Figure 5 As shown, the rib 231 is provided on the outer side of the side wall of the slide block 23, and the groove 214 is provided on the inner side wall of the side plate portion 211 of the base 21.

[0056] The locking member 22 is hinged to the slide block 23 so that the locking part 221 can move between a stop position and a clearance position. Specifically, as shown in the figure... Figure 3 As shown, a horizontal shaft 232 is provided in the slide 23, which is perpendicular to the first direction. The end of the locking member 22 away from the locking part 221 is rotatably connected to the shaft 232, so that the locking member 22 as a whole can rotate up and down around the shaft 232.

[0057] In order to lock the locking part 221 in the second direction, in some embodiments, such as Figure 3As shown, one or two side plates 211 of the base 21 are provided with a plurality of slots 213 that are spaced apart in sequence along a first straight direction. The top of the slots 213 are open. Correspondingly, the side of the locking member 22 is fixed with a protrusion 223 that can be inserted into the slot 213.

[0058] When the protrusion 223 is engaged in the slot 213, as Figure 4 As shown, at this time, the locking part 221 is in the stop position, and under the mutual restriction of the slot 213 and the protrusion 223, the locking member 22 is locked in the first linear direction. When it is necessary to move and adjust the position of the locking part 221 to adapt to the joint with different axial lengths, the locking member 22 can be flipped upward so that the protrusion 223 moves out of the opening. Then, the locking part 221 and the slide 23 are pulled together along the first linear direction until the position of the joint is adjusted to fit. Then, the locking part 221 is flipped to the stop position and locked into the slot 213 corresponding to this position. In this way, the locking part 221 is locked in the second direction to prevent the joint from being pulled out.

[0059] In addition, in order to ensure that the protrusion 223 can be well held in the bayonet 213, in some embodiments, an elastic member is provided between the locking member 22 and the slide 23. The elastic member is used to provide an elastic force to drive the locking part 221 to have a tendency to flip towards the stop position.

[0060] For example, such as Figure 3 and Figure 5 As shown, the elastic element can be a torsion spring 233, which is sleeved on the shaft 232. The two force-bearing ends of the torsion spring 233 are connected to the slide 23 and the locking element 22, respectively. The torque of the torsion spring 233 drives the locking element 22 to rotate towards the base 21 (i.e., to flip downwards). In this way, under the torque of the torsion spring 233, the protrusion 223 on the locking element 22 can be kept in the bayonet 213. When it is necessary to move the locking element 22, the locking element 22 can be flipped upwards by force, so that the locking element 22 overcomes the torque of the torsion spring 233 and flips upwards, so that the protrusion 223 is disengaged from the bayonet 213, and thus the locking element 22 can be moved.

[0061] Of course, in some other alternative embodiments (not shown in the figure), the elastic element can also be a tension spring, etc. The tension spring is located between the slide 23 and the locking element 22. One end of the tension spring is fixed to the locking element 22 and the other end is fixed to the slide 23. The locking element 22 is flipped downward by the tension of the tension spring.

[0062] In addition, in order to prevent the slide 23 from slipping off the base 21, in some embodiments, the anti-slip structure 2 further includes a limiting member, which is disposed on the base 21 to block the slide 23 from sliding off the base 21 in the second direction.

[0063] Preferably, the limiting member is detachably mounted on the base 21, for example, as shown in the figure. Figure 3 and Figure 5 As shown, the limiting component is a bolt 24, which is threaded onto the base plate 212 of the base 21. The bolt 24 prevents the slide block 23 from sliding out of the base 21. When it is necessary to remove the slide block 23 and the locking component 22, the bolt 24 can be unscrewed. Without the obstruction of the bolt 24, the slide block 23 can be slid out of the base 21 in the second direction.

[0064] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.
