Switching refers to the process of interconnecting some functional units, transmission paths or telecommunication circuits when signals need to be transported. The level and quality of switching, to a certain extent, determine the quality of communication in the entire communication network. A terminal is an input and output device connected to a computer system, usually far away from the computer.

[0003] During the use of communication exchange equipment, the magnetic field generated by the internal circuits and the external electromagnetic environment can cause electromagnetic interference to the signal transmission of the terminal equipment, thereby reducing the quality of communication exchange.

After the circuit is connected, an electric telescopic rod can move the rectangular shielding plate to the circuit box to shield the internal circuit magnetic field. Through the arc-shaped shielding plate and the rectangular shielding plate, the external magnetic field and the internal magnetic field can be shielded, which is beneficial for the antenna to receive and transmit signals, so as to solve the problems raised in the above-mentioned background technology.

When an electromagnetic field is detected on the side wall of the device shell, the shielding effect can be improved by adjusting the two arc shielding plates to overlapping positions. When the user installs the device shell on the chassis, the spring four on the arc shielding plate can squeeze the limit block two into the limit groove to fix the arc shielding plate, thereby preventing the arc shielding plate from shifting during use and ensuring the shielding effect of the arc shielding plate.

[0012] During use, first, the control switch circuit is turned on through the control panel. During the installation of the device shell, the device shell can squeeze the pressing block, so that the wiring head 1 can contact the wiring base 1, so that the circuit is turned on.

A square groove for the movement of the conductive block is opened on the bottom wall of the pressing block, and an electric contact connector is provided in the square groove, and the electric contact connector is electrically connected to the terminal through a wire.

[0014] When the device housing is installed, the conductive block can contact the electric contact connector in the square groove, thereby ensuring that the circuit is continuously connected, which is beneficial to the operation of the electric telescopic rod.

[0015] Preferably, the device shell is designed to be cylindrical, and the inner wall of the device shell matches the arc-shaped shielding plate, a rain shield is arranged outside the vent, and the rain shield is fixedly connected to the device shell, and a dust net is arranged inside the vent.

[0017] Preferably, a connecting rod is fixedly connected to the inner wall of the top of the rectangular shielding plate, and a movable groove 2 for moving the connecting rod is provided at the top of the circuit box, and a groove connected to the movable groove 2 is provided at the bottom end of the movable groove 2, and a limiting mechanism for fixing the connecting rod is arranged in the groove, and the limiting mechanism includes an electromagnet, and the electromagnet is electrically connected to the control panel, a limiting block 1 is arranged above the electromagnet, and a limiting hole matching with the limiting block 1 is provided at the bottom end of the connecting rod, and a small iron block matching with the electromagnet is fixedly connected to the bottom wall of the limiting block 1, and a spring 2 is sleeved on the outer side of the small iron block, and the limiting block 1 extends into the movable groove 2 through the spring 2.

[0018] During the installation of the rectangular shielding plate, the connecting rod can be moved into the movable groove two, and the limit block one can be embedded in the limit hole in the connecting rod through the spring two, so that the connecting rod is fixed in the movable groove two, and the rectangular shielding plate is further fixed on the circuit box. Therefore, after the user disconnects the power of the control switch through the control panel, the rectangular shielding plate can continue to be on the circuit box, which can avoid the electric telescopic rod from being continuously powered on, can reduce energy consumption, and increase the service life of the electric telescopic rod. When wiring is required, the user energizes the electromagnet through the control panel, so that the electromagnet can absorb the small iron block to make the limit block one slide out of the limit hole, making it convenient for the user to move the rectangular shielding plate out of the circuit box.

[0020] When the line is connected, as the current continues to be connected, the temperature in the installation slot will continue to rise, and the hot air will flow upward. When the exhaust fan is working, it can extract the hot air and transport it to the outside of the chassis, and cold air can enter the installation slot through the vents and round holes, thereby reducing the temperature in the installation slot, avoiding overheating and fire, and facilitating the use of the line.

The operation of the exhaust fan can be reasonably controlled, and energy consumption can be reduced while ensuring cooling, thereby reducing the cost of use.

[0023] Preferably, a plurality of line limiting mechanisms are evenly arranged in the installation groove, and the line limiting mechanism includes a mounting seat 1 and a mounting seat 2. A fastening belt is arranged in the mounting seat 1, and a buckle is fixedly connected to one end of the fastening belt.

When the user removes the buckle from the mounting seat, the spring sheets return to their original state and can drive the winding roller to rotate, thereby being able to wind up the tightening belt for easy retraction and release.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By setting an arc-shaped shielding plate and a rectangular shielding plate, and adjusting the position of the movable arc-shaped shielding plate, when it is detected that electromagnetic fields exist at different positions of the side wall of the device shell, the two arc-shaped shielding plates are respectively adjusted in the device shell. When an electromagnetic field is detected on the side wall of the device shell, the shielding effect can be improved by adjusting the two arc-shaped shielding plates to overlap positions. At the same time, the spring four on the arc-shaped shielding plate can squeeze the limit block two into the limit groove to fix the arc-shaped shielding plate, which can prevent the arc-shaped shielding plate from shifting during use and ensure the shielding effect of the arc-shaped shielding plate. After the circuit is connected, the electric telescopic rod can move the rectangular shielding plate to the circuit box to shield the internal circuit magnetic field. The arc-shaped shielding plate and the rectangular shielding plate can shield the external magnetic field and the internal magnetic field, which is beneficial for the antenna to receive and transmit signals.

[0029] 2. By setting a temperature detection component, when the circuit is connected, as the current continues to be connected, the temperature in the installation slot will continue to rise, and the hot air flows upward, so the memory alloy wire can stretch when heated, so that the memory alloy wire can push the second terminal head to contact the second terminal base, so that the exhaust fan is powered on, and the hot air can be extracted and transported to the outside of the chassis, and the cold air can enter the installation slot through the vents and the round holes, so that the temperature in the installation slot is reduced, which can avoid overheating and fire, and is beneficial to the use of the circuit, and when the temperature in the installation slot is reduced, the memory alloy wire shrinks due to the cold, so that the spring three can push the second terminal head to separate from the second terminal base, so that the exhaust fan is powered off, and the operation of the exhaust fan can be reasonably controlled. On the basis of ensuring cooling, energy consumption can be reduced, and the cost of use can be reduced.

[0030] 3. By setting a line limiting mechanism, when the user pulls out the fastening belt from the mounting seat and installs the buckle on the holder, the fastening belt can limit the line, which can prevent different lines from interlacing with each other, making it convenient for users to repair the lines. At this time, the spring sheets at both ends of the winding roller are in a winding state. When the user removes the buckle from the holder, the spring sheet returns to its original state and can drive the winding roller to rotate, thereby winding the fastening belt for easy retraction and release.

[0064] Working principle: First, the user detects the external magnetic field through the instrument, and then uses the arc-shaped shielding plate 18 to shield the interference of the external magnetic field on the antenna 8. When it is detected that the electromagnetic field exists at different positions of the side wall of the device housing 1, the two arc-shaped shielding plates 18 are adjusted in the device housing 1 respectively. When an electromagnetic field is detected on the side wall of the device housing 1, the shielding effect can be improved by adjusting the two arc-shaped shielding plates 18 to the overlapping position. When the user installs the device housing 1 on the chassis 2, the spring four 36 on the arc-shaped shielding plate 18 can squeeze the limit block two 37 into the limit groove 17 to fix the arc-shaped shielding plate 18, which can prevent the arc-shaped shielding plate 18 from deflecting during use and ensure the shielding effect of the arc-shaped shielding plate 18. The result is obtained, and then the device housing 1 is fixed, and the communication exchange terminal is installed through the mounting base 4. During use, the control switch circuit is first turned on through the control panel 21. During the installation of the device housing 1, the device housing 1 can squeeze the pressing block 23, so that the wiring head 27 can contact the wiring base 26 to connect the circuit, and further the electric telescopic rod 20 moves the rectangular shielding plate 19 to the circuit box 9 to shield the internal circuit magnetic field, which can ensure the use effect of the antenna 8 and is conducive to the antenna 8 receiving and transmitting signals. When the device housing 1 is detached, the spring 25 can push the pressing block 23 upward to facilitate re-triggering. When the device housing 1 is installed, the conductive block can contact the electric contact in the square groove. The connector contacts, thereby ensuring that the line is continuously connected, which is beneficial to the operation of the electric telescopic rod 20. When in use, the cylindrical device housing 1 can facilitate the rotation of the arc-shaped shielding plate 18, and can make the outermost arc-shaped shielding plate 18 fit with the device housing 1, which is beneficial to the adjustment of the arc-shaped shielding plate 18, and the rain shield can prevent rainwater from entering the device housing 1 to avoid damage to the integrated circuit board 6. At the same time, the dust net cooperates with the rain shield to prevent debris from entering the device housing 1. During the installation of the rectangular shielding plate 19, the connecting rod 42 can be moved into the movable groove 28, and the limit block 1 29 can be embedded in the limit hole in the connecting rod 42 through the spring 2 30, so that the connecting rod 42 is fixed in the movable groove 28, and the rectangular shielding plate 19 is further fixed to the circuit box 9. Therefore, after the user disconnects the power supply of the control switch through the control panel 21, the rectangular shielding plate 19 can continue to be on the circuit box 9, which can prevent the electric telescopic rod 20 from being continuously powered on, can reduce energy consumption, and increase the service life of the electric telescopic rod 20. When wiring is required, the user energizes the electromagnet 31 through the control panel 21, so that the electromagnet 31 can absorb the small iron block to make the limit block 29 slide out of the limit hole, which is convenient for the user to remove the rectangular shielding plate 19 from the circuit box 9. When the line is connected, as the current is continuously connected, the temperature in the installation slot 11 will continue to rise, and the hot air will flow upward, so the memory alloy wire 32 can be elongated by heat, so that the memory alloy wire 32 can push the wiring head 2 33 to contact the wiring base 2 34,The exhaust fan 7 is powered on and works. When the exhaust fan 7 works, the exhaust fan 7 can extract the hot air and transport it to the outside of the chassis 2, and the cold air can enter the installation groove 11 through the vent 5 and the round hole, so that the temperature in the installation groove 11 is reduced, which can avoid overheating and fire, and is beneficial to the use of the line. When the temperature in the installation groove 11 is reduced, the memory alloy wire 32 shrinks due to the cold, so that the spring 35 can push the second terminal head 33 to separate from the second terminal base 34, so that the exhaust fan 7 is powered off, and the operation of the exhaust fan 7 can be reasonably controlled. On the basis of ensuring the temperature reduction, it can also It can reduce energy consumption and use cost. When in use, after the user pulls out the fastening belt 38 from the mounting seat 13 and installs the buckle 39 on the card seat 16, the fastening belt 38 can limit the line, which can prevent different lines from interlacing with each other, making it convenient for users to repair the line. At this time, the spring pieces 41 at both ends of the winding roller 40 are in a winding state. When the user removes the buckle 39 from the card seat 16, the spring piece 41 can drive the winding roller 40 to rotate when it returns to its original state, so that the fastening belt 38 can be wound up, which is convenient for retracting and releasing.
