Abstract
The utility model discloses a built-in over-current overheating protector. The protector comprises a over-current overheating protector unit with a thermosensitive element, a base made of an insulation material, and a plug bush disposed on the base and in electric connection with the thermosensitive element in the over-current overheating protector unit. In the operation process, the plug bush is in plug-in connection with a plug sheet of an electric device. The plug bush is provided with a locking mechanism used for locking the plug sheet of the electric device. Preferably, the locking mechanism used for locking the plug sheet of the electric device comprises a groove and a tooth hook, wherein the groove is disposed on a plate body of the bottom part of the plug bush, and the tooth hook is disposed on the bottom surface of the groove and protrudes outward along the plate body of the bottom part of the plug bush. The protector can effectively prevent the plug sheet of an electric device from releasing from the plug bus of the protector in the operation process, and achieves more reliable and firm connection between the plug bush and the plug sheet, ensures a motor, an air conditioning compressor and other electric devices to be more reliably operated. The protector is simple in structure and convenient in manufacturing.
Description
Technical field
The utility model relates to a kind of non-electricity protector, particularly relate to a kind of can automatic cut-off power during at overcurrent overheat when power consumption equipments such as three phase electric machine, compressors of air conditioner, prevent the built-in overcurrent overheat protector that it burns.
Background technology
Existing built-in overcurrent overheat protector; comprise and there is overcurrent overheat protector unit, the pedestal of being made by insulating material of temperature-sensitive element and be arranged on the sleeve that the temperature-sensitive element on described pedestal and in overcurrent overheat protector unit is electrically connected to; when work; described sleeve is pegged graft and is connected with the inserted sheet of power consumption equipment; when power consumption equipment overcurrent overheat; by temperature-sensitive element, as bimetal leaf generation deformation automatic cut-off power, prevent that it from burning.
But; sleeve in existing protector does not possess auto-lock function; only rely on the dimensional fits plug-in type of sleeve and power consumption equipment inserted sheet to install; insertion by inserted sheet and sleeve and the contact engaging and separating force of extracting require to guarantee the installation reliability of its structure; its shortcoming is: after (1) sleeve is installed; the in the situation that of long-time heating power; manufactured materials fatigue because of sleeve; cause insert port size to become large; thereby very easily cause the contact resistance of sleeve and inserted sheet to increase; local pyrexia under power consumption equipment working, damaged line.(2) because protector is installed on compressor or motor, and the vibration producing when compressor, machine operation very easily causes inserted sheet to come off from sleeve, thereby causes compressor, electrical fault, even burns.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and can effectively prevent that power consumption equipment inserted sheet from coming off from protector sleeve, guarantees being connected more reliably and built-in overcurrent overheat protector firmly of sleeve and inserted sheet.
For solving the problems of the technologies described above; the utility model adopts a kind of so built-in overcurrent overheat protector; comprise and there is overcurrent overheat protector unit, the pedestal of being made by insulating material of temperature-sensitive element and be arranged on the sleeve that the temperature-sensitive element on described pedestal and in described overcurrent overheat protector unit is electrically connected to; when work; described sleeve is pegged graft and is connected with the inserted sheet of power consumption equipment, is provided with one for locking the locking mechanism of power consumption equipment inserted sheet on described sleeve.
As a kind of preferred embodiment of the present utility model, described for the locking mechanism that locks power consumption equipment inserted sheet by be arranged on sleeve bottom plate groove with it and be positioned in groove floor, along sleeve bottom plate body outwards outstanding hook form.
As another kind of preferred embodiment of the present utility model, describedly for locking the locking mechanism of power consumption equipment inserted sheet, by being arranged on sleeve bottom plate projection, outwardly with it, form.
Adopt after said structure, the utlity model has following beneficial effect:
Because the utility model arranges one for locking the locking mechanism of power consumption equipment inserted sheet on protector sleeve, this locking mechanism preferably forms with outside outstanding hook by being arranged on sleeve bottom plate groove with it, or by being arranged on sleeve bottom plate with it, outwardly projection forms, thereby when inserted sheet and the installation of sleeve plug-in type, tightly block inserted sheet with hook or the projection of sleeve one, make inserted sheet and sleeve machinery locked, thereby effectively prevented that power consumption equipment inserted sheet when work from coming off from protector sleeve, guaranteed compressor, the power consumption equipments such as motor can be safer, work reliably.

Embodiment
Referring to a kind of built-in overcurrent overheat protector shown in Fig. 1 to Fig. 7; comprise have temperature-sensitive element as the overcurrent overheat protector unit 1 of bimetal leaf, the pedestal 2 of being made by insulating material and by connect and fix be arranged on as described on pedestal 2 and with as described in the sleeve 3 that is electrically connected to of temperature-sensitive element in overcurrent overheat protector unit 1; described sleeve 3 is formed by sheet metal bending; when work; described sleeve 3 is pegged graft and is connected with the inserted sheet of power consumption equipment, is provided with one for locking the locking mechanism of power consumption equipment inserted sheet on described sleeve 3.
As a kind of preferred embodiment of the present utility model, as shown in Fig. 2～4, described for the locking mechanism that locks power consumption equipment inserted sheet by be arranged on the groove running through 4 on sleeve 3 bottom plate body 3-1 and be positioned on groove 4 bottom surfaces, along sleeve 3 bottom plate body 3-1 outwards outstanding hook 5 form.Described groove 4 and hook 5 form through punch process, and the shape of groove 4 can be semicircle, rectangle or other shape, and in addition, this groove 4 also can not run through plate body 3-1, and is only shallow slot, not shown in the figures.As shown in Figure 6, when the inserted sheet 7 of power consumption equipment is pegged graft installation with sleeve 3, tightly block the bottom face 7-1 of inserted sheet 7 with the hook 5 of sleeve 3 one, inserted sheet 7 can not be come off from sleeve 3, both mechanical types are locked, thus guaranteed the power consumption equipment such as compressor, motor can be safer, work reliably.
As another kind of preferred embodiment of the present utility model, as shown in Figure 7, described for the locking mechanism that locks power consumption equipment inserted sheet by be arranged on sleeve 3 bottom plate body 3-1, outwardly projection 6 forms.Like this when the inserted sheet 7 of power consumption equipment is pegged graft installation with sleeve 3, tightly block the bottom face 7-1 of inserted sheet 7 with the projection 6 of sleeve 3 one, inserted sheet 7 can not be come off from sleeve 3, thus guaranteed the power consumption equipment such as compressor, motor can be safer, work reliably, not shown in the figures.
Through on probation, after the inserted sheet of sleeve of the present utility model and power consumption equipment is pegged graft, both are not separated when work, guaranteed that the power consumption equipments such as motor, compressor of air conditioner can work more reliably, and of the present utility model simple in structure, easily manufactured, production cost is low, has obtained good practical function.
