Detailed Description
The utility model is specifically described below with reference to the accompanying drawings, as shown in the drawings, the utility model comprises a bracket 1, wherein a pair of insulators 2 are arranged on the bracket 1, an incoming contact 3 and an outgoing contact 5 are respectively arranged at the upper ends of the insulators, and locking bolts 4 are respectively arranged on the incoming contact and the outgoing contact; the insulator of the outgoing line contact end is provided with a support 6 and also comprises a pair of parallel blades 9, one end of each blade is connected with the support 6 in a shaft 7 in a shaft mode and is simultaneously connected with the outgoing line contact plug-in part 51 in a plug-in mode, and the other end of each blade is connected with the incoming line contact plug-in part 31 in a plug-in mode; a lock ring 10 is arranged on the knife blade, two groups of rubidium magnets 12 are arranged on the knife blade, and the rubidium magnets are respectively fixed on a knife blade plate of the knife blade 9 by bolts; the two groups of rubidium magnets are respectively close to the wire inlet contact plug-in part and the wire outlet contact plug-in part.
Screw holes are formed in the rear ends of the rubidium magnets, and bolts 13 penetrate through the cutter plates and then screw the rubidium magnets.
Preferably, two sets of rubidium magnets are symmetrically disposed at the ends of the knife plate.
The upper end of the insulator at the contact end of the incoming wire is provided with a locking fixed plate 11, the lower end of the locking ring is wound with a torsion spring 14, and a hook 101 of the locking ring is hung on the locking fixed plate.
