Description
[technical field]
The utility model relates to a kind of safeties for the electrical equipment overcurrent protection, particularly a kind of self-recovering type temperature insurance device.
[background technology]
The insurance means that have now for the overcurrent protection of electrical equipment and electronic equipment normally adopt fusible link, and when the electric current of the fusible link of flowing through is excessive, electric current raises rapidly its temperature, the time fusible link fuse, thereby cut off circuit, electrical equipment is protected; But fusible link belongs to disposable use element, can not automatically reset after fusing, after use once, will again change, increase the maintenance cost of product, the useful life of having reduced product, and the fusible link after changing has increased electronic waste, not environmental protection.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of reusable self-recovering type temperature insurance device is provided.
The purpose of this utility model is achieved in that it comprises housing, elastomeric element, moving contact, fixed contact, the memory spring of being made by memory alloy material, insulating base, there is a slideway in described housing, described insulating base is arranged on the end in slideway, described fixed contact is arranged on the medial extremity of insulating base, and is electrically connected to the first wire in penetrating housing and insulating base; Described elastomeric element is arranged on the other end in slideway, and its medial extremity acts on moving contact, and described moving contact is conflicted on fixed contact, and described moving contact is electrically connected to the second wire that penetrates housing; The two ends of described memory spring are connected to respectively on the end face of moving contact and insulating base.
In said structure, described insulating base inner face inwardly convexes with a round platform, and described fixed contact is arranged on the end face of this round platform, and the medial extremity of described memory spring butt insulating base also is set on round platform.
In said structure, described elastomeric element is metal compression spring, and described moving contact is connected with the second wire by compression spring.
In said structure, the end face that described moving contact contacts with compression spring convexes with a fixture block, and described fixture block snaps in this compression spring.
Described insulating base adopts ceramic material to make, and its outer end protrudes from housing, between outer end and housing, adopts epoxy sealing to be connected.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy to make, by the memory spring that compression spring and is made by memory alloy material is set in the slideway of housing, make moving contact between compression spring and memory spring, and moved left and right in slideway by the active force of two springs; Under normal temperature, the be stressed elastic force of spring of moving contact is conflicted on fixed contact, when electric current excessive, when in slideway, temperature raises, thereby memory spring is expanded by the effect shape memory of high temperature, promote moving contact and compressed to elastomeric element, moving contact and fixed contact are separated, cause the first wire and the second wire in off-state, reach the overcurrent protection to electrical appliance; When in slideway, temperature retrieval is to normal temperature, the be stressed effect of spring of moving contact automatically restores to the state contacted with fixed contact, disconnects the iterative cycles automatically recovered during normal temperature while realizing circuit high temperature.
[accompanying drawing explanation]
Fig. 1 is circuit connection diagram under the utility model normal temperature;
Fig. 2 is that the utility model circuit when high temperature disconnects schematic diagram.
[embodiment]
Below in conjunction with the drawings and the specific embodiments, the utility model is further described:
As depicted in figs. 1 and 2, self-recovering type temperature insurance device of the present utility model, comprise housing 1, elastomeric element 2, moving contact 3, fixed contact 4, the memory spring 5 of being made by memory alloy material, insulating base 6, there is a slideway 11 in described housing 1, the cross section of described slideway 11 is circular hole, and described elastomeric element 2, moving contact 3, fixed contact 4, memory spring 5 and insulating base 6 all are arranged in slideway; Described insulating base 6 is arranged on the end in slideway 11, and described fixed contact 4 is fixedly installed on the medial extremity of insulating base 6, and is electrically connected to the first wire 8 in penetrating housing 1 and insulating base 6; Described elastomeric element 2 is arranged on the other end in slideway 11, and its medial extremity acts on moving contact 3, and described moving contact 3 is conflicted on fixed contact 4, and described moving contact 3 is electrically connected to the second wire 9 that penetrates housing 1; The two ends of described memory spring 5 are connected to respectively on the end face of moving contact 3 and insulating base 6.
Shown in Fig. 1, temperature in housing is at normal temperatures the time, described moving contact 3 is moved to and the contacted position of fixed contact 4 by the active force of elastomeric element 2, and now the first wire 8 and the second wire 9 are in on-state, and plastic deformation occurs the memory spring 5 between moving contact 3 and insulating base 6.Shown in Fig. 2, when the electric current of flow through moving contact 3 and fixed contact 4 is excessive, electric current raises rapidly the temperature in slideway 11, thereby described memory spring 5 is expanded by the effect shape memory of high temperature, promoting moving contact 3 is compressed to elastomeric element 2, moving contact 3 and fixed contact 4 are separated, cause the first wire 8 and the second wire 9 in off-state.When the interior temperature of passage 11 of housing 1 returns to normal temperature, moving contact 3 is subject to the effect of elastomeric element 2 to automatically restore to the state contacted with fixed contact 4, disconnects the iterative cycles automatically recovered during normal temperature while realizing circuit high temperature.
