Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is entered Row is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belongs to the scope of the utility model protection.

Refer to Fig. 1-3, a kind of embodiment that the utility model is provided：A kind of low energy consumption permanent magnetism of overcurrent protection function takes off Fastening wire circle, including permanent magnet 9, fixed plate 11 and copper conductors 15, it is solid by connecting rod 8 between permanent magnet 9 and the inwall of shell 3 Fixed connection, and the right side of shell 3 is provided with and connects power port 2, is fixed between fixed plate 11 and the inwall of shell 3 by trip bolt 17 Connection, and connected between fixed plate 11 and rotating disk 12 by pivot pin 18, fixed and connected by hammerhead jib 19 between rotating disk 12 and tup 20 Connect, and tup 20 is arranged on the upside of surface plate 13, is fixedly connected between copper conductors 15 and surface plate 13 by insulating bar 14, And copper conductors 15 are arranged between contact head 6 and lower contact head 16, are provided with and are looped around between surface plate 13 and support frame 7 Spring 5 on insulating bar 14, and upper contact head 6 and lower contact head 16 be fixedly mounted on support frame 7, and police is provided with shell 3 It is electrically connected between report lamp 4, and warning light 4 and upper contact head 6 by wire 10, lower contact head 16 is with being looped around on permanent magnet 9 Wire 10 connect, and one end of wire 10 is connected with connecing power port 2, and the upper and lower ends of shell 3 are respectively provided with two retainer rings 1, Tup 20 is arranged on the lower end of permanent magnet 9, and is placed on during 20 normal work of tup on surface plate 13, and copper conductors 15 are in circuit It is connected under normal operating conditions with lower contact head 16, support frame 7 is made up of insulating materials component, and support frame 7 and shell 3 is interior Wall is fixedly connected.

Operation principle；When using when the electric current in circuit is excessive, electric current by with connect power port 2 connect wire 10 Access in wire 10, due to having high current to pass through in wire 10, electrical conductor has magnetic, and the attraction that permanent magnet 9 is produced is big In the gravity of tup 20, tup 20 is caused to leave surface plate 13, at this time the spring 5 between surface plate 13 and support frame 7 will be exhausted Edge bar 14 lifts so that copper conductors 15 are separated with lower contact head 16 so that circuit disconnects, while contacting shape with upper contact head 6 Into closed-loop path, warning light 4 is flashed, and when electric current becomes low current again, tup 20 is pressed on surface plate 13 again so that Copper conductors 15 are turned on lower contact head 16, and circuit forms normal loop.
