Fig. 3 is contact pin described in the utility model and alarm circuit structure diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figure 1, the utility model provides a kind of safety device with fusing warning function, including hollow insulation
Pipe 1, the hollow insulation tube 1 are made of transparent glass, from external it can be seen that structure inside hollow insulation tube 1.It is described
The left and right ends of hollow insulation tube 1 are respectively arranged with the first conductive cap 2 and the second conductive cap 3, first conductive cap 2 and second
Conductive cap 3 is made of metallic copper.The both ends of hollow insulation tube 1 are sealed by the first conductive cap 2 and the second conductive cap 3.
As shown in Fig. 2, fusible link 4, connecting plate 5 and spring 6, the connection have been located at it in the hollow insulation tube 1
Plate 4 and spring 5 are made of metal material.The left end of fusible link 4 is fixedly connected with the first conductive cap 2, the right end of fusible link 4
It is fixedly connected with connecting plate 5, connecting plate 5 is connected again by spring 6 with the second conductive cap 3.Spring 6 is in the state of elongation, melts
Fracture of wire 4 is subject to certain pulling force, but the size of pulling force will not make fusible link 4 deform.The first conductive cap 2 passes through fusing at this time
Silk 4, connecting plate 5 and spring 6 are electrically connected with the realization of the second conductive cap 3.First conductive cap 2 and the second conductive cap 3 are used as two
Safety device is linked into circuit by terminals, safety device is made to have the function of with traditional insurance silk identical.When in circuit
When electric current is excessive, fusible link 4 can generate heat fusing, disconnect circuit.Due to the pulling force effect of spring 6, fusible link 4 under normal circumstances
It will not be elongated, but will be broken rapidly when fusible link 4 melts, compared with conventional fuse silk, when earth-current is excessive,
The time that fusible link 4 disconnects in the utility model is shorter.
