Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment 1
As shown in figs 1 to 6, a kind of noiseless overcurrent overheat protector provided in the present embodiment, including sealed shell
Body 1 and two lead-out wires 2 for stretching out housing 1, are provided with support 3 in housing 1, movable contact spring 4 are provided with the top of support 3, in support 3
Lower section is provided with static contact 5, is provided with moving contact 6 in the one end of movable contact spring 4, the other end is connected with one of lead-out wire 2, stationary contact
The one end of piece 5 is connected by a heating wire 7 with static contact 8, and static contact 8 coordinates with the apical grafting of moving contact 6, the other end of static contact 5
It is connected with another lead-out wire 2, it is fixed on support 3 provided with the up and down loose slot 9 of movable contact spring 4 can be made in housing 1
There is the mounting bracket 10 for wrapping up heating wire 7, the top of mounting bracket 10 is provided with opening 11, gold is hinged with one end of opening 11
Belong to piece 12, in the other end of opening 11 provided with sheet metal 12 to be carried out to spacing limiting section 13, the top of sheet metal 12, which is provided with, stretches
Go out the locating rod 14 of housing 1, the lower section being hinged in sheet metal 12 and mounting bracket 10 is provided with is locked at the first peace by sheet metal 12
The first spring 16 in tankage 15, provided with the second spring 18 being locked at by movable contact spring 4 in second mounting groove 17 on support 3,
