DETAILED DESCRIPTION
[0034] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0035] The cable room structure of the integrated node switch cabinet of the utility model comprises a cable room door 1, an upper hook 3 and a lower hook 4 are respectively provided on both sides of the cable room door 1, and the two sides of the cable room door 1 are respectively connected to the left side plate 14 and the right side plate 15 of the cable room through the lower hook 4, a protective plate 7 is provided between the upper part of the cable room door 1 and the upper crossbeam 6, a lower crossbeam 13 is provided below the cable room door 1, a handle 2 is provided on the surface of the cable room door 1, an electromagnetic lock bracket 10 is provided on the inner side of the cable room door 1, and an electromagnetic lock 8 corresponding to the electromagnetic lock bracket 10 is provided in the cable room. Among them, a decorative sealing plate 12 is provided on the outside of the cable room door 1. A plurality of protective coils 11 are provided on the cable room door 1. A pad 5 is provided at the connection between the cable room door 1 and the upper hook 3. A pad 5 is provided at the connection between the cable room door 1 and the lower hook 4. The electromagnetic lock 8 is installed in the cable room through the electromagnetic lock mounting plate 9. The lock tongue of the electromagnetic lock 8 corresponds to the hole body of the electromagnetic lock bracket 10. The left side plate 14 and the right side plate 15 are provided with holes corresponding to the upper hook 3 and the lower hook 4. Cable room door 1 is installed on the cable room of the integrated node switch cabinet ( Figure 1 , 2 ).
[0036] The utility model improves the protection level and meets the IP4X protection level requirements of the existing ring network cabinet. A protective plate is added under the upper beam, and there is no 1mm gap after the cable room door is closed. Figure 3 ); Add a pad between the upper hook, lower hook and cable room door ( Figure 4 , 5 ) to prevent the cable room door from swinging left and right in the assembly gap to expose the upper hook and lower hook installation slots, so that all locations can meet the protection level ( Figure 5 ).
[0037] In the case of limited space, the cable room door is equipped with a handle, and a movable and convenient handle is used. After the handle is inserted into the notch of the cable room door, the rivet is riveted in the handle hole so that the handle cannot fall off. The handle is hung on the cable room door when it is free; when the cable room door is opened, the handle is flipped up to a horizontal state, which is enough to open the cable room door with the hand; after the decorative cover is installed, the handle is flipped down to fit the cable room door ( Figure 6-10 ).
[0038] The electromagnetic lock structure fixed in the cabinet is used. After the cable room door is opened, there is no need to plug in or unplug the electromagnetic lock connection wire. Use the electromagnetic lock mounting plate to fix the electromagnetic lock in the cabinet, and install the electromagnetic lock bracket on the cable room door. When the cabinet is powered, the locking rod of the electromagnetic lock extends out of the electromagnetic lock bracket hole, and the cable room door cannot be lifted up to open. When the cabinet is not powered, the locking rod of the electromagnetic lock retracts, and the cable room door can be lifted up to open ( Fig.11 , 12 ).
[0039] The cable room door uses a φ110 flat-plate protective ring. It is convenient for the installation of connectors, and can ensure that hands cannot touch the live cable room after the cable room door is closed, and does not affect the installation of decorative cover plates. The upper hook and the lower hook are used together, so that the cable room door can be pulled out and removed, and the installation is smooth, which is convenient for the installation of quick connectors.
[0040] After the cable room door is closed, the lower hook is far from the upper end. If the cable room door is pulled up by force, the cable room door may deviate to one side, causing the lower door interlock to be unlocked and the cable room door to be opened. Adding an upper hook can limit the left and right shaking of the cable room door, effectively ensuring the reliability of the cable door interlock ( Fig.13 , 14 ).
[0041] The lower hook is lengthened and rivets are added to allow the cable door to be pulled out, making it easier to install the quick connector ( Fig.15 ).
[0042] The cable room door is pulled to the end of the lower hook and the rivet is blocked at the left and right panels. The cable room door is hung ( Fig.16). Connect the quick connector from the protective coil to the cable room, and reach into the cable room from above the cable room door to install the quick connector. Push the cable room door forward, insert the upper hook into the slots on the left and right panels, and push it until the cable door fits with the left and right panels. Press the cable room door to trigger the interlock, and close the cable room door. ( Fig.17 ).
[0043] When more space is needed for maintenance and inspection, the cable room door can be removed. Lift the hanging cable room door upwards, and the rivet at the end of the lower hook can be released from the notched notch on the left and right panels to remove the cable room door ( Fig.18 ).
[0044] A decorative cover is installed outside the cable compartment to keep the appearance beautiful and unified with other matching cabinet types. When the quick connector is not in use, install the decorative cover and remove it before operation.
