Description

A kind of hand-reset protector
Technical field
The utility model relates to a kind of being used for and uses the device of in time protecting when unusual, especially a kind of hand-reset protector at electrical equipment.
Background technology
High-tech rapid technological improvement in recent years, special with rapid changepl. never-ending changes and improvements especially in the field of microelectronics correlation technique processing procedure, so the electronic correlation product has goed deep into becoming some indispensable in the modern life in each family and all trades and professions.Certainly human wants is more and more, uses in order to make electronic installation can reach greater functionality, and the target of electronic product towards the diversification effect strided forward.But electronic product is under the considering of safety, must be detected to the voltage in the circuit and current loading or for defeated, guarantees that electronic product reduces to minimum to the mankind or ancillary equipment to the mankind's injury or destruction.
Summary of the invention
The utility model provides a kind of hand-reset electric current protector that is used to protect electronic product at the problem that proposes in the above-mentioned background technology.
The realization the technical solution of the utility model is as follows:
A kind of hand-reset protector; it has upper shell and lower house; lower house is provided with support, fixed contact support, moving contact support; moving contact support is fixedly installed on the support, and moving contact is fixed on the moving contact support by movable contact spring, and movable contact spring is provided with heater strip; the end of heater strip is fixedly installed on the support; the fixed contact support is provided with fixed contact, and moving contact is arranged on the fixed contact front, and the side of moving contact and fixed contact is provided with spacer assembly.
Described spacer assembly is made up of spring and isolator, and spring one end is fixedly installed on the lower house, and the other end is arranged in the isolator, and isolator one side is a division board, and this division board is arranged on the side of fixed contact and moving contact.
Described movable contact spring is a bimetal leaf.
Adopted above-mentioned technology; a kind of hand-reset protector; behind its place in circuit; heater strip and bimetal leaf produce heat under the excessive situation of load; bimetal leaf sudden change upset after temperature raises directly drives moving contact and leaves fixed contact; this moment is because the elastic force of spring promotes isolator; the position that the division board of isolator side enters between moving contact and the fixed contact isolates; when the needs circuit working; manually promote isolator; extrusion spring, the position that division board is left between moving contact and the fixed contact resets.The beneficial effects of the utility model are simple in structure, can in time prevent the injury that brings when electric appliance load is excessive, coefficient of safety height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure, 1, lower house, 2, the fixed contact support, 3, moving contact, 4, isolator, 5, heater strip, 6, support, 7, moving contact support, 8, spring, 9, fixed contact, 10, bimetal leaf, 11, upper shell, 12, division board.
Embodiment
As Fig. 1; shown in Figure 2; a kind of hand-reset protector; it has upper shell 11 and lower house 1; lower house 1 is provided with support 6; fixed contact support 2; moving contact support 7; moving contact support 7 is fixedly installed on the support 6; moving contact 3 is fixed on the moving contact support by movable contact spring; movable contact spring is a bimetal leaf 10; movable contact spring is provided with heater strip 5; the end of heater strip 5 is fixedly installed on the support 6, and fixed contact support 2 is provided with fixed contact 9, and moving contact 3 is arranged on fixed contact 9 fronts; moving contact 3 is provided with spacer assembly with the side of fixed contact 9; spacer assembly is made up of spring 8 and isolator 4, and spring 8 one ends are fixedly installed on the lower house 1, and the other end is arranged in the isolator 4; isolator 4 one sides are division board 12, and this division board 12 is arranged on the side of fixed contact 9 and moving contact 3.
Behind this protector place in circuit; heater strip 5 produces heats with bimetal leaf 10 under the excessive situation of load; bimetal leaf 10 sudden change upset after temperature raises directly drives moving contact 3 and leaves fixed contact 9; this moment is because the elastic force of spring 8 promotes isolator 4; the position that the division board 12 of isolator 4 sides enters between moving contact 3 and the fixed contact 9 isolates; when the needs circuit working; manually promote isolator 4; extrusion spring 8, the position that division board 12 is left between moving contact 3 and the fixed contact 9 resets.
