The dust-proof cover main body 101 can effectively block external dust and impurities, and try to prevent external dust and impurities from falling into the inside of the wire harness installation groove 4, effectively extending the service life of the device. Both ends of the top of the dust-proof cover main body 101 are provided with wire harness fixing holes 103, and the diameters of the wire harness fixing holes 103 are the same as those of the wire harness installation grooves 4. The wire harness fixing holes 103 are respectively arranged directly above and directly below the wire harness installation grooves 4, which can facilitate the fixing of the installed wire harness; a sealing sleeve 105 is fixedly connected inside the wire harness fixing holes 103. By using the sealing sleeve 105 to seal the wire harness, it can prevent external dust and impurities from falling into the inside of the wire harness installation groove 4 through the wire harness fixing holes 103. Both ends of the dust-proof cover main body 101 are fixedly connected with mounting blocks 104, and both ends of the top and bottom of the circuit protector main body 3 are fixedly connected with fixing blocks 102. Thread grooves 108 are opened inside the fixing blocks 102, and threaded rods 106 are threadedly connected inside the thread grooves 108. One end of the threaded rod 106 close to the mounting block 104 is fixedly connected with a limit card block 107. A limit hole is opened inside the mounting block 104, and the limit hole is matched with the limit card block 107. By rotating the threaded rod 106 and inserting the threaded rod 106 into the thread groove 108, the limit card block 107 can be pushed into the inside of the mounting block 104, and the dust-proof cover main body 101 can be installed on the circuit protector main body 3.
