Description
Technical field
The utility model is related to the overheat protector technical field in emergency protective device, especially a kind of miniature Thermal protection
Device.
Background technology
Protector is applied on the electric tools such as motor, ballast, increasingly accurate compact with these tool designs,
It is less and less that the structure of protector is also designed, and Mini-sized protector is not only conveniently installed to narrow and small position due to small volume, also may be used
It is installed on required product with by mosaic mode.
The utility model patent of Application No. 2009203099441 discloses a kind of Miniature heat protector, with shell and
Thermal protector inner core, described thermal protector inner core is by fixing the entirety that board component and fixed seat riveting are constituted, described fixation
Board component has movable contact, bimetal leaf and fixed plate, and bimetal leaf one end is welded with movable contact, the other end and fixed plate weld
Together, fixed seat is provided with the stationary contact being connected as a single entity by injection, and movable contact is oppositely arranged with stationary contact.It is quiet in this patent
Contact is laminated structure, stationary contact and static contact disjunctor injection moulding, and fixed seat is insulator, due to thermal protector overall volume
Smaller, static contact is smaller with the contact area of insulation fixed seat, and insulation distance is small, is susceptible to high voltage short circuit phenomenon, reliability
It is low.
Utility model content
The utility model is susceptible to high voltage short circuit phenomenon, reliable low asks for Miniature heat protector in the prior art
Topic, and a kind of Miniature heat protector of research and design.
The technical solution adopted in the utility model is：
A kind of Miniature heat protector, including fixed plate, insulation fixed seat, temperature-sensing element, moving contact, static contact and stationary contact
Head, it is characterised in that the static contact is bending structure, one end riveting has static contact, and the other end is stretched from the insulation fixed seat
Go out.
Further, the static contact bends into a ladder.
Further, the static contact has a single order ladder, including the contact mounting surface that is parallel to each other and wiring face, also wraps
Include angle >=90 ° of bending side connecting the two, the bending side and contact mounting surface.
Further, the temperature-sensing element is bimetal leaf.
Relative to prior art, the beneficial effects of the utility model are：Into a ladder, increase quiet by by static contact bending
Contact and the contact area of insulation fixed seat, so as to increase insulated lengths, greatly reduce and the hidden danger of high voltage short circuit occur, increase
The reliability of Miniature heat protector.

Specific embodiment
In order that technical problem, technical scheme and beneficial effect that the utility model is solved become more apparent, below
With reference to drawings and Examples, the utility model is further elaborated.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
In description of the present utility model, it is to be understood that term " radial direction ", " axial direction ", " on ", D score, " top ",
The orientation or position relationship of the instruction such as " bottom ", " interior ", " outward " are based on orientation shown in the drawings or position relationship, merely to just
Described with simplified in description the utility model, must be with specific side rather than the device or element for indicating or imply meaning
Position, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.In description of the present utility model
In, unless otherwise indicated, " multiple " is meant that two or more.
, it is necessary to explanation, unless otherwise clearly defined and limited, term " is pacified in description of the present utility model
Dress ", " setting ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly
Connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary.For the ordinary skill in the art,
Concrete meaning of the above-mentioned term in the utility model can as the case may be understood.
Miniature heat protector as depicted in figs. 1 and 2, including fixed plate 1, insulation fixed seat 2, temperature-sensing element 3, moving contact
4th, static contact 5 and static contact 6；Temperature-sensing element 3 uses bimetal leaf, and one end of temperature-sensing element 3 is welded on the fixed plate 1 of top
On, the downside that other end riveting has moving contact 4, temperature-sensing element 3 is contacted with insulation fixed seat 2, and insulation fixed seat 2 has to accommodate to be felt
The cavity of warm element 3, static contact 5 with insulation fixed seat 2 can integrated injection molding, static contact 5 be bending structure, one end riveting have
Static contact 6, the other end stretches out from insulation fixed seat 2.
As a kind of preferred embodiment, static contact 5 is bent into a ladder.Which increase static contact 5 solid with insulation
The contact area of reservation 2, that is, increase insulation distance, greatly reduces the risk of high voltage short circuit, Miniature heat protector more may be used
Lean on.
In the present embodiment, static contact 5 is bent into the structure with single order ladder, and referring to Fig. 3 and Fig. 4, static contact 5 includes phase
Mutually parallel contact mounting surface 51 and wiring face 53, also including bending side connecting the two 52, bending side 52 and contact mounting surface
51 angle >=90 °.
Can similarly be apparent from, the bendable of static contact 5 is converted into multistage ladder, with it is a greater degree of increase insulation away from
From.
The end difference connecting wire in the end of fixed plate 1 and the wiring face 53 of static contact 5, such fixed plate 1, temperature-sensitive unit
Part 3, moving contact 4, static contact 6 and static contact 5 form galvanic circle.
Specifically, the operation principle of Miniature heat protector of the present utility model is：
When Miniature heat protector accesses circuit, under heating effect of current effect, mutation upset drives dynamic touching to temperature-sensing element 3
First 4 are moved together so that moving contact 4 is separated with static contact 6, so that circuit loop is cut off, when heat disperses on temperature-sensing element 3
Afterwards, temperature-sensing element 3 can automatically reset recovery, and two contacts contact so as to connect circuit loop again.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, by above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this utility model technological thought completely.This practicality
New technical scope is not limited to the content on specification, it is necessary to determine its according to right technical
Scope.
