Abstract
The present utility model relates to a thermal protector requiring manual hand-operated power off resetting. The thermal protector is mainly composed of an insulation pedestal, a static contact sheet, a moving contact sheet, a bimetallic sheet, a PTC heating chip, a static contact, a moving contact, a touch control end, a wiring end, an embedding groove pedestal and other parts. As the static contact sheet and the moving contact sheet are long, and the insulation pedestal is short and small, the touch control end and the wiring end of the thermal protector can be formed on two sides of the insulation pedestal after the static contact sheet and the moving contact sheet are installed on the insulation pedestal, and the previous thermal protector in which each component (such as the bimetallic sheet, the static contact, the moving contact, etc) of the touch control end is arranged on the insulation pedestal is improved. That is to say, as the insulation pedestal is improved to be smaller and shorter, more space of two sides of the insulation pedestal are reserved for arranging the touch control end and the wiring end, thus the whole volume of the protector can be smaller and more exquisite, the suitable scope is wider, and production costs are lower.
Description
Technical field
The utility model relates to a kind of overtemperature protection device that is applied on the various electric equipment products.
Background technology
Thermal protector is a kind of Protector for electric appliances that utilizes bimetal leaf can reverse rapidly and disconnect within surpassing the protection temperature range.At present, the heat of commonly using on each electric equipment products is protected device and mainly is divided into two types: a kind of is not to be with the heat of PTC chip to protect device, do not protect device after unusually moving with the heat of PTC chip, protecting the device environment temperature when heat drops to a certain degree, the bimetal leaf that heat is protected device can automatically reset again, the electric equipment products energising is worked on, and this heat is protected device makes the working power of electrical equipment repeatedly be switched on and cut off, and security performance is relatively poor.Another kind is the thermal protector with the PTC chip, and this heat with the PTC chip is protected device after unusually moving, and needs manually deenergization; after heat is protected the device cooling; bimetal leaf just can reset, and can not make the working power of electrical equipment repeatedly be switched on and cut off, and security performance is better.
Yet present existing heat with the PTC chip is protected device and is mainly also existed structure simple not, compact, exquisite, uses on precision, the exquisite electric equipment products so that it can't be used for some, and then affects widely applying of this thermal protector.
The utility model content
It is a kind of simple in structure, compact that the purpose of this utility model is to provide, and volume is small and exquisite, and good, the applied widely needs of security performance are the thermal protector of power-off restoration manually.
The technical solution of the utility model is achieved in that
A kind of needs are the thermal protector of power-off restoration manually, comprise insulating base, static contact, movable contact spring, bimetal leaf, PTC euthermic chip, fixed contact and moving contact, its characteristics are that the length of described static contact, movable contact spring makes longer than the length of insulating base, described static contact, movable contact spring are fixedly installed in respectively bottom surface and the end face of insulating base, and are formed with the touch-control end in the left side of insulating base and are formed with terminals in the left side of insulating base; Be positioned at the embedding slot seat that also is provided with a pair of confession bimetal leaf setting-in on the movable contact spring end face of touch-control end, described bimetal leaf is set mutually by its two end and embedding slot seat and is installed on the movable contact spring end face; Described moving contact is arranged on the movable contact spring bottom surface that is positioned at the touch-control end; Described fixed contact is arranged on the static contact end face that is positioned at the touch-control end, and described moving contact touches mutually with this fixed contact; Also be provided with the slotted eye for PTC euthermic chip setting-in on the described insulating base, described PTC euthermic chip is flush-mounted in this slotted eye, and two electrode tips of this PTC euthermic chip respectively with static contact, movable contact spring mutually electricity touch.
In order to realize protecting preferably the main body of thermal protector; and make it have the good characteristics of water resistance; the utility model also comprises a casing; above-mentioned insulating base and be set in together in this casing with static contact, movable contact spring, bimetal leaf, PTC euthermic chip, fixed contact and the moving contact of this insulating base assembling also is respectively arranged with sealing of hole insulating paper and sealing of hole resin glue at the port of casing.
The utility model makes it have following technique effect owing to adopting technical scheme noted earlier:
(1) owing to making static contact, movable contact spring longer; insulating base is done shorter and smalllyer structure; after making static contact, movable contact spring be installed on the insulating base; can be at other touch-control end and the terminals that form thermal protector of insulating base two side sides, change existing thermal protector each parts (such as bimetal leaf, fixed contact, moving contact etc.) of touch-control end are arranged at the structure in the insulating base.That is to say, this product is little by insulating base is done, it is short to do, and is in order to vacate more space in insulating base two sides touch-control end and terminals to be set, so can make the overall volume of this product can do littlely, more exquisite, make its scope of application wider, and production cost is lower.Simultaneously, the terminals of this product are to consist of by stretching out in insulating base outer static contact, movable contact spring end, install or arrange special connecting terminal members on the insulating base thereby not be used in, and then can play the volume that further reduces this product, with play further saving and produce raw material, the effect that reduces production costs.
(2) owing to adopting in casing of whole thermal protector main body suit; and adopt insulating paper and sealing of hole resin glue to seal in the port of casing; so that this product has good insulation preformance, water resistance is good, security performance is good characteristics; can use widely in the various adverse circumstances and use, thereby widen further the scope of application of this product.
(3) this product have advantages of simple and compact for structure, volume is small and exquisite, water resistance is good, security performance is good, can be widely used on the various electric equipment products such as motor, heating electrical appliance etc. to use.
Below in conjunction with accompanying drawing the utility model is further described:
