[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective electrical devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions. Control cabinets are commonly used in power generation, distribution, and substations.

[0003] Control cabinets require a large number of terminals. Existing terminals cannot effectively restrain the cables after wiring, making them prone to swaying under external force and eventually detaching. To solve these technical problems, we have designed a control cabinet terminal with line protection functionality. Utility Model Content

[0004] The purpose of this utility model is to provide a control cabinet terminal with line protection function, which has the advantage of binding the part of the cable near the terminal connection. This solves the problem that when the terminal is in use, it cannot bind the cable after wiring, making the cable easily swing when subjected to external force, and eventually causing the cable to detach.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal for a control cabinet with line protection function, comprising a terminal board, a baffle connected to the center of the front side of the terminal board, an isolation plate connected to the top and bottom of the baffle, several notches and slots opened on the top and bottom of the terminal board, a plug connected to the center of the notches and slots, several conductive plates connected to the front side of the terminal board and located between two isolation plates, voltage-conducting blocks provided on the top and bottom of the front side of the conductive plates, a winding bolt provided on the front side of the voltage-conducting blocks, the rear side of the winding bolt passing through the voltage-conducting blocks and the conductive plates and threadedly connected to the terminal board, an arc-shaped pressure groove opened on the top of the opposite side of the conductive plates and voltage-conducting blocks, L-shaped support plates connected to the left and right sides of the rear side of the terminal board, a protective component connected to the front side of the two L-shaped support plates, the protective component comprising four support sleeves, the rear sides of the four support sleeves respectively connected to the top and bottom of the front surface of the two L-shaped support plates, and a limit rod movably connected to the inner wall of the support sleeves through bearings.

[0006] Preferably, the back surface of the baffle is provided with a number of positioning slots for use with the conductive plate, the top and bottom of the front surface of the L-shaped support plate are provided with positioning holes, the rear side of the isolation plate is connected to the terminal plate, and the front side of the terminal plate is provided with a number of positioning screw holes for use with the winding bolts.

[0007] Preferably, the surfaces of the two inserts and the two isolation plates on opposite sides are on the same plane as the top and bottom of the terminal plate, and the front surfaces of the isolation plates and the baffles are on the same plane.

[0008] Preferably, a positioning plate is movably fitted on the front side of the four limiting rods. An operation window is opened through the front surface of the positioning plate. Several restraining plates are connected to the top and bottom of the back surface of the positioning plate. A slot for use with the arc-shaped pressure groove is opened through the top of the restraining plate. The slot is used with the insert block. The positioning plate is located in front of the baffle and the isolation plate.

[0009] Preferably, the four corners of the front surface of the positioning plate are provided with movable holes for use with the limiting rod, and the top and bottom of the inner wall of the movable holes are provided with movable notches.

[0010] Preferably, the outer side of the limiting rod slides in contact with the inner wall of the moving hole, and the left and right sides of the front side of the limiting rod are connected with blocks that cooperate with the moving notch. A rotating sleeve is fixedly sleeved on the outer side of the limiting rod and located on the rear side of the positioning plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a combination of protective components, notch slots, insert blocks, and arc-shaped pressure grooves to effectively restrain the portion of a cable near the terminal connection. A positioning plate is fitted over four limiting rods. Moving the positioning plate backward until the restraining plate is inserted into the notch slot and the insert block is inserted into the slot, at which point the stop block is positioned in front of the positioning plate. Then, rotating the rotating sleeve 90 degrees causes the limiting rods to rotate 90 degrees, resulting in the stop block and the movable notch being staggered at 90-degree intervals. The restraining plate and insert block effectively restrain the cable near the terminal connection, preventing it from swinging and detaching unnecessarily. Attached Figure Description

Isolation plates 6 are connected to the top and bottom of the baffle 5. Several notches 7 are opened on the top and bottom of the terminal board 1. Insert blocks 8 are connected to the center of the notches 7. Several conductive plates 9 are connected to the front side of the terminal board 1 and between the two isolation plates 6. Voltage conductive blocks 10 are provided on the top and bottom of the front side of the conductive plates 9. Winding bolts 4 are provided on the front side of the voltage conductive blocks 10. The rear side of 4 passes through the voltage conductive block 10 and the conductive plate 9 and is threadedly connected to the terminal plate 1. The top of the opposite side of the conductive plate 9 and the voltage conductive block 10 are provided with arc-shaped pressure grooves 11. The left and right sides of the rear side of the terminal plate 1 are connected with L-shaped support plates 2. The front sides of the two L-shaped support plates 2 are connected to the protective component 3. The protective component 3 includes four support sleeves 34. The rear sides of the four support sleeves 34 are respectively connected to the top and bottom of the front surface of the two L-shaped support plates 2. The inner wall of the support sleeve 34 is movably connected to the limit rod 33 through the bearing.

[0020] The back surface of the baffle 5 is provided with several positioning slots 12 that cooperate with the conductive plate 9. The top and bottom of the front surface of the L-shaped support plate 2 are provided with positioning holes. The rear side of the isolation plate 6 is connected to the terminal plate 1. The front side of the terminal plate 1 is provided with several positioning screw holes that cooperate with the winding bolts 4. The positioning slots 12 make it easy for the baffle 5 to be locked to the outside of the conductive plate 9. The positioning holes make it easy to use bolts to pass through the L-shaped support plate 2 to position the terminal plate 1 in the control cabinet. The cooperation of the winding bolts 4 and the positioning screw holes makes it easy to position the conductive block 10.

[0021] The surfaces of the two inserts 8 and the two isolation plates 6 on opposite sides are on the same plane as the top and bottom of the terminal plate 1. The front surface of the isolation plate 6 and the front surface of the baffle 5 are on the same plane. The two adjacent isolation plates 6 can isolate the two adjacent conductive plates 9 to prevent them from contacting each other. The isolation plate 6, baffle 5, inserts 8, terminal plate 1 and L-shaped support plate 2 are all made of insulating material.

[0022] A positioning plate 32 is movably fitted on the front side of the four limiting rods 33. An operation window 31 is opened through the front surface of the positioning plate 32. Several binding plates 35 are connected to the top and bottom of the back surface of the positioning plate 32. A slot 36 is opened through the top of the binding plate 35 to cooperate with the arc-shaped pressure groove 11. The slot 36 is used in conjunction with the insert block 8. The positioning plate 32 is located in front of the baffle 5 and the isolation plate 6. The outside of the insert block 8 slides in contact with the inner wall of the slot 36. The longitudinal length of the slot 36 is greater than the longitudinal length of the insert block 8. The front side of the inner wall of the slot 36 corresponds to the arc-shaped pressure groove 11 and is also arc-shaped.

[0023] The four corners of the front surface of the positioning plate 32 are provided with moving holes 39 for use with the limiting rod 33. The top and bottom of the inner wall of the moving hole 39 are provided with moving notches 310; the moving holes 39 facilitate the forward and backward movement of the limiting rod 33.

[0024] The outer side of the limiting rod 33 slides in contact with the inner wall of the moving hole 39. Both the left and right sides of the front side of the limiting rod 33 are connected to the stop block 38 that cooperates with the moving notch 310. The outer side of the limiting rod 33 and the rear side of the positioning plate 32 are fixedly fitted with a rotating sleeve 37. Through the cooperation of the stop block 38 and the moving notch 310, the positioning plate 32 is conveniently limited and prevented from detaching from the limiting rod 33.

[0025] In use, the conductive block 10 is fitted over the outside of the winding bolt 4, and then the stripped cable is wound around the outside of the winding bolt 4. The back side of the winding bolt 4 is aligned with the positioning screw hole. The winding bolt 4 is rotated clockwise to rotate into the positioning screw hole, thus completing the positioning and installation of the cable. The part of the installed cable away from the winding bolt 4 is located inside the arc-shaped pressure groove 11 (or the stripped cable part can be inserted between the conductive plate 9 and the conductive block 10, and then the winding bolt 4 can be tightened). The positioning plate 32 is fitted over the four limiting rods 33. The positioning plate 32 is moved backward until the binding plate 35 is inserted into the notch 7 and the insert 8 is inserted into the slot 36. At this time, the stop 38 is located in front of the positioning plate 32. Then, the rotating sleeve 37 is rotated 90 degrees, which drives the limiting rod 33 to rotate 90 degrees, so that the stop 38 and the moving notch 310 are staggered at 90 degrees. The binding plate 35 and the insert 8 are used to bind the connection of the cable near the terminal to prevent it from swinging and falling off at will.

[0026] In summary, this control cabinet terminal with line protection function solves the problem that the terminal cannot restrain the wired cable during use, making the cable easily swing when subjected to external force, and eventually causing the cable to detach. This is achieved through the combined use of the protective component 3, the notch 7, the plug block 8, and the arc-shaped pressure groove 11.
