A wiring hole is provided on one side of the switchgear body, through which wiring inside the switchgear body extends. A wire groove is provided in the middle of the upper end of the wiring rack, with the wiring located inside the wire groove. Fastening structures are provided on both sides of the wire groove, and these fastening structures are detachably mounted on the upper end of the wiring to limit its position. This invention supports the wiring exposed outside the switchgear body, and, in conjunction with the fastening structures on the upper end of the cable rack, limits the position of the wiring through the fastening mechanism, thereby effectively preventing mechanical wear caused by wiring movement.

The arc surfaces of upper insulating rubber pad 15 and lower insulating rubber pad 9 engage with terminal body 2. Second magnetic block 17 is fixed on the bottom wall of groove 16. First magnetic block 14 is inserted into groove 16 and first magnetic block 14 and second magnetic block 17 attract each other.

[0024] In use, the lower insulating rubber pad 9 is inserted into the groove of the U-shaped plate 6 so that the T-shaped block 10 is engaged with the T-shaped groove 8. Then, the U-shaped plate 6 is engaged with the side wall of the terminal frame 3 so that the plug 5 is inserted into the socket 7. The position of the wiring body 2 extending from the outer wall of the low-voltage switchgear body 1 is adjusted so that the wiring body 2 is placed in the wiring arc groove 4 on the terminal frame 3 and abuts against the arc surface of the lower insulating rubber pad 9, so that the upper insulating rubber pad 15 is engaged with the side wall of the fixing plate 12, and the first magnetic block 14 is inserted into the recess 16 and attracts the second magnetic block 17.
