[0002] In electrical automation power distribution systems, to improve the space utilization of distribution cabinets, multiple residual current devices (RCDs) are typically installed tightly against each other on the distribution rail. In existing technology, RCDs are usually elastically clipped onto the distribution rail, lacking a lateral locking structure. When one RCD needs to be removed, the friction force can cause adjacent RCDs to shift or even fall off, posing a safety hazard.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

Through holes are provided on opposite walls of the hollow C-shaped frame, and clamping blocks are movably inserted through these through holes. An upper inclined surface is provided on the upper wall of each clamping block. A spring post is installed between the clamping block and the hollow C-shaped frame. A rotating rod is movably inserted into the hollow C-shaped frame, and an auxiliary rotating component is installed at one end of the rotating rod. A driving component is installed on the rotating rod and inside the hollow C-shaped frame, and the driving component matches the clamping block. The fastener includes several types of horizontal bars, each with a receiving groove on its opposite wall surface. The clamping block is movably inserted into the receiving groove.

Detailed Implementation

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figure 1-5 An electrical automation protection switch includes a leakage current protection device body 1, on which an anti-interference structure is provided, the anti-interference structure being composed of a snap-fit ​​component and a fixing component; It should be noted that the specific structure and working principle of the residual current device (RCD) body 1 can refer to the NXBLE-63 model 2P RCD produced by Chint Group. The RCD is installed on the power distribution rail in the manner of existing technology. The fixing part is installed parallel to the power distribution rail above the power distribution rail. After the RCD body 1 is installed on the power distribution rail, the snap-fit ​​part and the fixing part match each other. In actual production, the snap-fit ​​part and the fixing part can be designed to standard part size to facilitate mass production. Specifically, the snap-fit ​​component includes a hollow C-shaped frame 2, which is installed on the upper wall of the residual current device body 1. Through holes are opened on the opposite wall surfaces of the hollow C-shaped frame 2, and clamping blocks 3 are movably inserted through the through holes. An upper inclined surface 4 is provided on the upper wall surface of the clamping block 3. A spring post 5 is installed between the clamping block 3 and the hollow C-shaped frame 2. A rotating rod 6 is movably inserted into the hollow C-shaped frame 2. An auxiliary rotating component is installed at one end of the rotating rod 6. A driving component is installed on the rotating rod 6 and inside the hollow C-shaped frame 2. The driving component is matched with the clamping block 3. Specifically, the fastener includes a series of horizontal bars 7, each of which has a receiving groove 8 on its opposite wall surface. The clamping block 3 is movably inserted into the receiving groove 8. The top surface of the series of horizontal bars 7 has a top groove 9, and the auxiliary rotating component is movably attached to the top groove 9. It should be noted that the hollow C-shaped frame 2 can be made into an integral structure with the outer shell of the residual current device body 1. After the residual current device body 1 is installed on the power distribution rail, the hollow C-shaped frame 2 covers the horizontal bar 7. At this time, the clamping block 3 is aligned with the receiving groove 8, the spring column 5 is in a natural state, and the clamping block 3 is fully retracted in the hollow C-shaped frame 2. Specifically, the drive assembly includes a movable frame 10, a rotating rod 6 located inside the hollow C-shaped frame 2 with threads, the movable frame 10 being movably fitted onto the rotating rod 6 via the threads, and two support rods 11 symmetrically installed on the movable frame 10, each support rod 11 having a top block 12 installed at one end, and the top block 12 having a lower inclined surface 13 that matches the upper inclined surface 4. It should be noted that after the residual current device (RCD) body 1 is installed on the distribution rail, the auxiliary rotating assembly is attached to the top groove 9. Rotating the rotating rod 6 moves the moving frame 10, which in turn moves the two support rods 11 and the top block 12 on them. Under the matching of the upper inclined surface 4 and the lower inclined surface 13, the clamping block 3 is pushed to move along the axis of the spring column 5. When the top block 12 is attached to the inner wall of the hollow C-shaped frame 2, the clamping block 3 is inserted into the receiving groove 8, and the clamping blocks 3 on the upper and lower sides hold the horizontal bar 7. At this time, the spring column 5 is in a stretched state. Through the clamping of the clamping blocks 3, the residual current device (RCD) is activated. The main body 1 of the residual current device is fixed in the transverse direction on the power distribution rail. Multiple residual current device bodies 1 are installed on the power distribution rail in close contact with each other. If it is necessary to remove one of the residual current device bodies 1, rotate the rotating rod 6 to reset the drive component. The spring column 5 rebounds and drives the clamp 3 to be retracted into the hollow C-shaped frame 2. Then, multiple residual current device bodies 1 can be removed. The two adjacent residual current device bodies 1 will not move with the power distribution rail due to the matching of the snap-fit ​​and the fixing parts, thus eliminating the hidden danger of adjacent residual current device bodies 1 even falling off the power distribution rail. Preferably, the lower wall of the clamping block 3 is provided with an anti-slip layer 14 to enhance the friction between the clamping block 3 and the receiving groove 8 and prevent the clamping block 3 from moving in the lateral direction of the receiving groove 8. As a preferred and further option, a guide rod 15 is installed on the inner wall of the hollow C-shaped frame 2, and the movable frame 10 is movably fitted onto the guide rod 15 for guiding and limiting the movable frame 10. As a preferred and further option, the auxiliary rotating assembly includes a support column 16, which is installed at one end of the rotating rod 6. A pressure block 17 is movably fitted on the support column 16. After the leakage current protection device body 1 is installed on the power distribution rail, the pressure block 17 fits against the top groove 9 to support one end of the rotating rod 6. The pressure block 17 is made of rubber material and has a large friction with the top groove 9. When the rotating rod 6 is rotated, the rotating rod 6 drives the support column 16 to rotate on the pressure block 17. Preferably, the number of spring posts 5 is at least 2.
