Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment protection technology, and more specifically, it relates to a network interface protection device for electrical secondary equipment. Background Technology

[0002] As a core component of the power system, secondary electrical equipment undertakes critical tasks such as real-time monitoring, precise control, dynamic adjustment, and safety protection of primary equipment, serving as a vital support for ensuring the stable and efficient operation of the power system. Network interfaces, as the core communication components of secondary electrical equipment, are the key hubs for data interaction, command transmission, and information sharing between devices. Their communication quality and operational stability directly affect the execution efficiency of various control commands in the power system, as well as the accuracy of overall operation and maintenance management, thus playing a crucial role in the safe and reliable operation of the power system.

[0003] Based on the above, the network interfaces of electrical secondary equipment generally lack effective protection. During use, accidental collisions can easily cause loose connections and damaged pins, directly disrupting communication stability. When not in use, the interfaces are susceptible to dust accumulation and moisture corrosion, which can lead to poor contact and seriously affect the reliable operation of the equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a network interface protection device for electrical secondary equipment. This device solves the problem of insufficient effective protection for the network interfaces of existing electrical secondary equipment. By setting up a protective structure, on the one hand, two sets of stabilizing plates are driven by a bidirectional screw to clamp the wire harness towards each other. Mechanical fixation is achieved through the tight fit between the circular wire harness hole and the wire harness, effectively preventing plug loosening due to accidental collisions and ensuring equipment stability. On the other hand, after the plug is removed, a first spring pushes the sealing plate to automatically reset and seal the wire harness hole, effectively preventing dust, moisture, and other impurities from entering the interface, avoiding poor interface contact, and extending the interface's service life.

[0005] This utility model discloses a network interface protection device for electrical secondary equipment, which is achieved through the following specific technical means: A network interface protection device for electrical secondary equipment, specifically comprising: a top shell of the equipment and a protective structure; The top shell of the device is provided with an interface at one end, and a protective structure is provided on the top shell of the device. The protective structure includes the following components: Fixed frame: Fixedly connected to one end of the top shell of the equipment. A two-way screw is rotatably installed on the fixed frame. A limit rod is provided on the other side of the two-way screw. A rotating handle is fixedly connected to the top end of the two-way screw. At the same time, through slots are opened at the upper and lower ends of the fixed frame. Connecting inner frame: Fixedly connected to the inside of the fixed frame, the connecting inner frame is provided with a stabilizing plate, and the two sides of the stabilizing plate are fixedly connected with extension protrusions. The extension protrusions are respectively provided with threaded holes and limiting holes, and the middle of the stabilizing plate is provided with a wire harness hole. Movable groove: Located inside the stabilizing plate, the movable groove is fixedly connected to two sides with fixed vertical rods, and a first spring is provided on the outside of the fixed vertical rods; Enclosure plate: Located in the movable groove, the two ends of the enclosure plate are fixedly connected with connecting tabs, and the connecting tabs are provided with movable sliding holes. The enclosure plate is slidably installed on the fixed vertical rod through the movable sliding holes.

[0006] Furthermore, the stabilizing plate has semi-circular wire harness holes, and the two sets of wire harness holes form a circular structure when they are opposite each other.

[0007] Furthermore, the bottom of the top shell of the equipment is provided with a bottom shell, and an assembly assembly is provided between the top shell and the bottom shell. The assembly assembly includes an extension convex frame and a fixed inner plate. The top of the bottom shell is fixedly connected to the extension convex frame, and three sets of fixed inner plates are fixedly connected to the inner walls on both sides of the extension convex frame.

[0008] Furthermore, a fixed crossbar is fixedly connected between the fixed inner plates, and a second spring is provided on the outer side of the fixed crossbar.

[0009] Furthermore, a movable slider is provided on the outer side of the fixed crossbar, and a guide hole is provided on the movable slider.

[0010] Furthermore, the bottom of both sides of the top shell of the device is provided with a limiting slot, and a misalignment groove is provided in the middle of the limiting slot, while the connecting slider is fitted and locked in the limiting slot.

[0011] This utility model provides a network interface protection device for electrical secondary equipment, which has the following advantages: By setting up a protective structure, on the one hand, two sets of stabilizing plates are driven by a bidirectional screw to clamp the wire harness in opposite directions. The tight fit between the circular wire harness hole and the wire harness achieves mechanical fixation, which can effectively prevent the plug from loosening due to accidental collision and ensure the stability of the equipment. On the other hand, after the plug is pulled out, the first spring pushes the sealing plate to automatically reset and seal the wire harness hole, which can effectively prevent dust, moisture and other impurities from entering the interface, avoid poor interface contact, and extend the service life of the interface.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a network interface protection device for electrical secondary equipment, including: equipment top shell 1 and protective structure 2; One end of the top shell 1 of the equipment is provided with an interface 101, and the top shell 1 of the equipment is provided with a protective structure 2, which includes the following components: Fixed frame 201: Fixedly connected to one end of the top shell 1 of the equipment. A two-way screw 2011 is rotatably installed on the fixed frame 201. A limit rod 2012 is provided on the other side of the two-way screw 2011. A rotating handle 2013 is fixedly connected to the top end of the two-way screw 2011. At the same time, through slots 2014 are opened at the upper and lower ends of the fixed frame 201. Connecting inner frame 202: Fixedly connected to the inside of fixed frame 201, the connecting inner frame 202 is provided with a stabilizing plate 2021, the two sides of the stabilizing plate 2021 are fixedly connected with extension protrusions 2022, the extension protrusions 2022 are respectively provided with threaded holes 2023 and limiting holes 2024, and the middle of the stabilizing plate 2021 is provided with a wire harness hole 2025. Movable groove 203: It is located inside the stabilizing plate 2021. Fixed vertical rods 2031 are fixedly connected to both sides of the movable groove 203. A first spring 2032 is provided on the outside of the fixed vertical rods 2031. Enclosure plate 204: Located in the movable groove 203, the two ends of the enclosure plate 204 are fixedly connected with connecting protrusions 2041, and the connecting protrusions 2041 are provided with movable sliding holes 2042. The enclosure plate 204 is slidably installed on the fixed vertical rod 2031 through the movable sliding holes 2042.

[0022] The stabilizing plate 2021 has semi-circular wire harness holes 2025, and the two sets of wire harness holes 2025 form a circular structure when they are opposite each other.

[0023] In use, the plug is inserted into the interface 101, and then the handle 2013 is rotated to drive the bidirectional lead screw 2011 to rotate. The bidirectional lead screw 2011 engages with the threaded hole 2023 on the extension protrusion 2022. However, the limiting hole 2024 on the other set of extension protrusions 2022 is guided by the limiting rod 2012, causing the bidirectional lead screw 2011 to drive the two sets of stabilizing plates 2021 to move towards each other, thereby approaching the wire harness of the plug and stabilizing it through the wire harness hole 2025. This ensures the stability of the plug and the interface 101 and prevents the plug from becoming loose due to collision. When not in use, the handle 2013 is rotated in the opposite direction to drive the two sets of stabilizing plates 2021 in the opposite direction via the bidirectional lead screw 2011. The cable harness can be moved so that the plug can be pulled out of the interface. When clamped, the cable harness squeezes the sealing plate 204 at the cable hole 2025, causing the sealing plate 204 to retract into the movable groove 203. When the cable harness stops squeezing the sealing plate 204, the sealing plate 204 squeezes the first spring 2032 on the fixed vertical rod 2031 through the connecting protrusion 2041, causing the first spring 2032 to become elastic. When the pressure is lost, the first spring 2032 releases its elasticity and pushes the connecting protrusion 2041 to move. The connecting protrusion 2041 then drives the sealing plate 204 to reset, thereby sealing the cable hole 2025 through the sealing plate 204 to prevent dust from entering the interface 101.

[0024] Example 2: Based on Example 1, wherein, as Figure 5 and Figure 6 As shown, the bottom of the top shell 1 of the equipment is provided with a bottom shell 301, and an assembly assembly 3 is provided between the top shell 1 and the bottom shell 301. The assembly assembly 3 includes an extension protrusion 3011 and a fixed inner plate 3012. The top of the bottom shell 301 is fixedly connected to the extension protrusion 3011, and three sets of fixed inner plates 3012 are fixedly connected to the inner walls on both sides of the extension protrusion 3011.

[0025] A fixed crossbar 302 is fixedly connected between the fixed inner plates 3012, and a second spring 3021 is provided on the outside of the fixed crossbar 302.

[0026] A movable slider 303 is provided on the outer side of the fixed crossbar 302. A guide hole 3031 is provided on the movable slider 303. A connecting slider 3032 is fixedly connected to one outer end of the movable slider 303. The connecting slider 3032 extends to the outside through the through groove 3033 on the extension protrusion 3011. An anti-slip tooth 3034 is provided on one outer end of the connecting slider 3032.

[0027] Limiting slots 304 are provided on both sides of the bottom of the top shell 1 of the equipment. A misalignment groove 3041 is provided in the middle of the limiting slot 304, and the connecting slider 3032 is fitted and locked in the limiting slot 304.

[0028] When internal maintenance of the network device is required, the top cover 1 of the device can be removed by pulling the connecting slider 3032 to move it to the misalignment groove 3041 for easy maintenance. During installation, the top cover 1 of the device is simply installed on the extension protrusion 3011. At this time, the connecting slider 3032 is in the middle of the limiting slot 304. Then, the connecting slider 3032 is released. As the connecting slider 3032 initially moves, it causes the moving slider 303 to compress the second spring 3021, causing the second spring 3021 to undergo elastic deformation. Then, the second spring 3021 pushes the moving slider 303 to move under the reaction force. The moving slider 303 then drives the connecting slider 3032 to reset and be locked into the limiting slot 304, thus completing the installation.

[0029] The specific usage and function of this embodiment are as follows: In this invention, during use, the plug is inserted into the interface 101, and then the rotating handle 2013 is turned to rotate the bidirectional lead screw 2011. The bidirectional lead screw 2011 engages with the threaded hole 2023 on the extension protrusion 2022. Meanwhile, the limiting hole 2024 on the other set of extension protrusions 2022 is guided by the limiting rod 2012, causing the bidirectional lead screw 2011 to move the two sets of stabilizing plates 2021 toward each other, thus approaching the wire harness of the plug. This allows the wire harness to be stably clamped through the wire harness hole 2025, ensuring the stability of the plug and the interface 101 and preventing the plug from loosening due to collision. When not in use, the plug can be unplugged by rotating the rotating handle 2013 in the opposite direction, causing the bidirectional lead screw 2011 to move the two sets of stabilizing plates 2021 in the opposite direction. When the wire harness is clamped, it compresses the sealing plate 204 at the wire harness hole 2025, causing the sealing plate 204 to retract into the movable groove 203. When the wire harness stops compressing the sealing plate 204, the sealing plate 204 compresses the first spring 2032 on the fixed vertical rod 2031 through the connecting protrusion 2041, causing the first spring 2032 to become elastic. When the pressure is lost, the first spring 2032 releases its elasticity and pushes the connecting protrusion 2041 to move. The connecting protrusion 2041 then drives the sealing plate 204 to reset, thereby sealing the wire harness hole 2025 through the sealing plate 204. This effectively prevents dust, moisture and other impurities from entering the interface 101, avoiding poor contact of the interface 101 and extending the service life of the interface 101.
