Technical Field

[0001] This utility model relates to the field of communication management machine technology, specifically a communication management machine that prevents interface loosening. Background Technology

[0002] The communication management unit, also known as the DPU, is a management machine that uses a high-performance embedded computing platform, has multiple downlink communication interfaces and one or more uplink network interfaces. It is equivalent to a front-end machine or monitoring computer and has a high-performance real-time database system. It is mainly used to organize and summarize the communication data of all intelligent monitoring / protection devices in the substation and send it to the upper-level master station system in real time to realize remote signaling, telemetry and other functions.

[0003] Currently, terminal blocks are installed on the interface of the communication management unit. The connection to the cable is achieved by rotating the screws on the terminal blocks to tighten the stripped end of the cable. The terminal blocks can provide a certain degree of anti-loosening effect for the cable. However, under external pulling force or after long-term use, the screws can easily wear down the stripped end of the cable, causing the cable to loosen inside the terminal block, resulting in poor wiring connection. Utility Model Content

[0004] The purpose of this utility model is to provide a communication management unit that prevents interface loosening, thereby overcoming the aforementioned defects in the prior art. According to this utility model, a communication management unit that prevents interface loosening includes a main unit, indicator lights on the surface of the main unit, a plurality of wiring terminals, connection ports, and switches evenly arranged on the back of the main unit, and mounting ears fixedly installed on both sides of the main unit.

[0005] A connector is installed on the terminal block, a groove is formed through the surface of the connector, a clamp is installed in the groove, the clamp is slidably installed in the groove, a handle is installed on one side of the clamp, and a fixing component is provided in the handle.

[0006] Preferably, the terminal block includes a plurality of connection holes formed on the surface of the terminal block, a metal plate is installed at the bottom of the connection holes, and a screw is threadedly installed above the terminal block.

[0007] Preferably, a groove is formed through the surface of the connector, the groove corresponding to the connection hole of the terminal block, and a clamping plate is installed on the top of the groove. The clamping plate is designed as an L-shape and has elasticity and deformation under force.

[0008] Preferably, a sliding groove is formed through one side of the groove, and a sliding groove is formed on the other side of the groove. A sliding rod is fixedly installed on one side of the clamping plate, and a handle is installed on the outside of the sliding rod. A sliding rod is fixedly installed on the other side of the clamping plate. The sliding rod is slidably connected to the sliding groove, and the sliding rod is slidably connected to the sliding groove.

[0009] Preferably, the fixing component includes a three-slide groove inside the handle, sliders fixedly installed on both sides of the slide rod, the sliders being slidably connected to the three-slide groove, fixing holes being opened above and below both ends of the slide groove, and two fixing blocks being fixedly installed on the inner side of the handle, the fixing blocks being slidably connected to the fixing holes.

[0010] Preferably, a rubber pad is installed at the bottom of the connection hole of the terminal block, the metal sheet is located in the middle of the rubber pad, the height of the rubber pad is greater than the height of the metal sheet, and the size of the rubber pad is greater than the size of the screw.

[0011] The beneficial effects of this utility model are:

[0012] 1. Install a connector on the terminal block and make a groove through the surface of the connector. The groove corresponds to the connection hole of the terminal block. Install a clamp on the top of the groove. The clamp is designed to be L-shaped and has elasticity and deformation under force. The stripped end of the cable is squeezed into the clamp from below. The clamp is deformed by bending upward under pressure, which clamps the cable downward. On the basis of fixing the cable through the terminal block, this further prevents the cable from becoming loose and keeps the line with good connection effect.

[0013] 2. A sliding groove is formed through one side of the groove, and a sliding groove is formed on the other side of the groove. A sliding rod is fixedly installed on one side of the clamping plate, and a handle is installed on the outside of the sliding rod. A sliding rod is fixedly installed on the other side of the clamping plate. The sliding rod is slidably connected to the sliding groove, and the sliding rod is slidably connected to the sliding groove. Sliding the handle upward causes the clamping plate to bend upward, and then the stripped end of the cable is fixed in the terminal block. Releasing the handle causes the clamping plate to return the sliding rods to their original positions due to its elasticity. This structure can prevent the clamping plate from squeezing the cable during installation, making it convenient for users to install cables.

[0014] 3. A third groove is made inside the handle, and sliders are fixedly installed on both sides of the first slide rod. The sliders are slidably connected to the third groove. Fixing holes are made above and below both ends of the first groove. Two fixing blocks are fixedly installed on the inside of the handle. The fixing blocks are slidably connected to the fixing holes. Before installing the cable, pull the handle outward and slide it diagonally upward to the top. Then push the handle inward to fix the fixing blocks in the fixing holes. This allows the clamp to maintain an upward bending shape. After all the cables are installed in the connection holes, return the handle to the initial position so that the clamp springs back to its original shape to fix the cable, improving the user's work efficiency.

[0015] 4. Install a rubber pad at the bottom of the connection hole of the terminal block. The metal piece is located in the middle of the rubber pad. The height of the rubber pad is greater than the height of the metal piece, and the size of the rubber pad is greater than the size of the screw. When the screw is rotated to fix the cable, the screw presses the cable downward to contact the metal piece, and at the same time, it also presses the rubber pad to deform it, which plays a certain role in blocking the screw. This can prevent the screw from being tightened too much and causing damage to the cable, thereby ensuring a stable connection of the line. Attached Figure Description

Detailed Implementation

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe a communication management unit for preventing interface loosening or several specific implementations of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up / down and left / right are not limited to their strict geometric definitions, but rather include tolerances for reasonable and inconsistent machining or human errors. The specific features of this communication management unit for preventing interface loosening are described in detail below:

[0026] Reference Figures 1-8 According to an embodiment of the present invention, a communication management machine for preventing interface loosening includes a host 1, an indicator light 5 is provided on the surface of the host, a plurality of wiring terminals 2, connection ports 3 and switches 4 are evenly arranged on the back of the host 1, and hanging ears 6 are fixedly installed on both sides of the host 1. This is a conventional structure of a communication management machine for preventing interface loosening.

[0027] The terminal block 2 includes a plurality of connection holes 22 formed on the surface of the terminal block 2, a metal sheet 21 is installed at the bottom of the connection hole 22, and a screw 20 is threadedly installed on the top of the terminal block 2.

[0028] When the cable is subjected to external pulling force or after long-term use, the screw 20 on the terminal 2 will cause wear to the stripped end of the cable, which may cause the cable to loosen in the terminal 2. In order to solve this problem, the inventors have considered making the following improvements.

[0029] A connector 7 is installed on the terminal block 2, and a groove 8 is formed through the surface of the connector 7. The groove 8 corresponds to the connection hole 22 of the terminal block 2. A clamping plate 9 is installed on the top of the groove 8. The clamping plate 9 is designed to be L-shaped and has elasticity and can deform under force. The stripped end of the cable is squeezed into the clamping plate 9 from below. The clamping plate 9 is squeezed and bends upward, which clamps the cable downward. On the basis of fixing the cable through the terminal block 2, the cable is further prevented from becoming loose, so that the line maintains a good connection effect.

[0030] Furthermore, when the cable is placed into the connection hole 22, it is squeezed by the clamping plate 9. To facilitate installation, a sliding groove 10 is obliquely opened through one side of the groove 8, and a sliding groove 21 is obliquely opened through the other side of the groove 8. A sliding rod 12 is fixedly installed on one side of the clamping plate 9, and a handle 14 is installed on the outside of the sliding rod 12. A sliding rod 23 is fixedly installed on the other side of the clamping plate 9. The sliding rod 12 is slidably connected to the sliding groove 10, and the sliding rod 23 is slidably connected to the sliding groove 21. Sliding the handle 14 upward causes the clamping plate 9 to bend upward, and then the stripped end of the cable is fixed in the terminal 2. Then, the handle 14 is released, and the clamping plate 9, due to its own elasticity, causes the sliding rod 12 and the sliding rod 23 to return to their original positions. The above structure can avoid being squeezed by the clamping plate 9 during installation, making it convenient for users to install cables.

[0031] Furthermore, since there is more than one connection hole 22 on the terminal block 2, a fixing component is provided inside the handle 14 to facilitate cable installation. The fixing component includes a three-way groove 15 opened inside the handle 14, sliders 16 are fixedly installed on both sides of the sliding rod 12, and the sliders 16 are slidably connected to the three-way groove 15. Fixing holes 17 are opened above and below both ends of the three-way groove 10, and two fixing blocks 18 are fixedly installed on the inside of the handle 14, and the fixing blocks 18 are slidably connected to the fixing holes 17. Before installing the cable, the handle 14 is pulled outward and then slid diagonally upward to the top, and then the handle 14 is pushed inward to fix the fixing blocks 18 in the fixing holes 17. This allows the clamp 9 to maintain an upwardly bent shape. After all the cables are installed in the connection holes 22, the handle 14 is returned to the initial position, allowing the clamp 9 to spring back to its original shape to fix the cable, thus improving the user's work efficiency.

[0032] Furthermore, to prevent the screw 20 on the terminal 2 from causing wear to the stripped end of the cable, a rubber pad 19 is installed at the bottom of the connection hole 22 of the terminal 2. The metal piece 21 is located in the middle of the rubber pad 19, and the height of the rubber pad 19 is greater than the height of the metal piece 21. The size of the rubber pad 19 is greater than the size of the screw 20. When the screw 20 is turned to fix the cable, the screw 20 presses the cable downward to contact the metal piece 21, and at the same time, it also presses the rubber pad 19 to deform it, which plays a certain role in blocking the screw 20. This can prevent the screw 20 from being tightened too much and causing damage to the cable, thereby ensuring a stable connection of the line.

[0033] The specific implementation process is as follows:

[0034] Before installing the cable, locate the corresponding terminal 2, pull the handle 14 outward, and then slide the handle 14 diagonally upward to cause the clamp 9 to deform and bend upward. After sliding to the top, push the handle 14 inward to fix the clamp 9. Then, install the stripped end of the cable into the connection hole 22. After completing the connection, pull the handle 14 outward and slide it back to its original position. Then, push the handle 14 inward to fix it again, so that the clamp 9 clamps the cable downward, further preventing loosening.

[0035] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
