Abstract
The utility model provides a passive high-temperature resistant proximity switch. The passive high-temperature resistant proximity switch comprises a housing and an inner core. The housing is provided with fixing nuts. The inner core comprises an inner core housing and a contact point installed inside the inner core housing. The contact point is connected with a magnet through a cylinder. The contact point follows the magnet to move up and down for matching. Contacts connected with external copper wires are arranged above and below the contact point. An installation threaded seat is arranged on the upper end of the inner core housing. The installation threaded seat is matched with the housing. The inner core housing is made of a high-temperature resistant material. According to the utility model, the inner core housing is made of the high-temperature resistant material, so that the range of usage temperature is enlarged, and the passive high-temperature resistant proximity switch is applicable to most usage occasions; and by adopting the structure of the passive high-temperature resistant proximity switch, the range of usage temperature is further enlarged.
Description
Technical field
The utility model relates to the approach switch field, is specifically related to a kind of passive high temperature resistant approach switch.
Background technology
Approach switch also is proximity switch; claim again static position switch; it is except can completing Stroke Control and position limitation protection; or a kind of checkout gear of non-contact type; as detecting accessory size and testing the speed etc., also can be used for the automatic linking of frequency conversion counter, variable-frequency pulse generator, level control and procedure etc.
Often be applied to the signal feedback of various domestic, the import equipment in the chemical water treatment system, ash and slag handling system, soda acid metering system, condensate system, limewash system in the enterprises such as electric power, oil, chemical industry, metallurgy, boiler soot-blowing, light a fire, send bleed, the renewal product of all kinds of travel switches such as air draft, Electrically operated gate, provide the operating position monitoring to show.Because approach switch often is applied in the comparison rugged environment, therefore, it is more extensively better that its serviceability temperature scope needs, and the serviceability temperature scope of current approach switch is less, under application and the environment of-35-180 ℃, and more in rugged environment, approach switch easily lost efficacy or error larger, affect practical function.
The utility model content
In order to solve the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of passive high temperature resistant approach switch, and it has solved the less deficiency of approach switch serviceability temperature scope in the past.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of passive high temperature resistant approach switch, it comprises shell and inner core, described shell is provided with hold-down nut, described inner core comprises inner core housing and the contact point that is arranged on the inner core enclosure interior, and described contact point is connected with magnet by cylinder, and described contact point coordinates with the magnet upper and lower translation, the upper and lower two ends of described contact point are provided with the contact of external copper cash, described inner core housing upper end is provided with the installation threaded block, and described installation threaded block and shell are suitable, and described inner core housing adopts exotic material to make.
Preferably, described inner core housing lower end is provided with adjusting nut, has the hole suitable with cylinder in the middle of described adjusting nut, and described cylinder is connected with magnet after running through adjusting nut.
Preferably, described shell is provided with two hold-down nuts.
Preferably, between described hold-down nut, be provided with at least one pad.
The beneficial effects of the utility model are that the employing exotic material, as housing, makes its serviceability temperature scope augmentation, is applicable to most use occasions, and adopts structural design described in the utility model, enlarges its serviceability temperature scope.
The accompanying drawing explanation
Fig. 1 is the structural representation of shell of the present utility model.
Fig. 2 is the structural representation of the inner core with adjusting nut of the present utility model.
Fig. 3 is the enlarged drawing in circle in Fig. 2.
Fig. 4 is of the present utility model not with the structural representation of the inner core of adjusting nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Referring to Fig. 1, Fig. 2 and Fig. 4, the utility model comprises shell and inner core, described shell is provided with hold-down nut 1, the contact point 5 that described inner core comprises inner core housing 3 and is arranged on inner core housing 3 inside, described contact point 5 is connected with magnet 6 by cylinder 9, described contact point 5 coordinates with magnet 6 upper and lower translations, described contact point is provided with the contact 4 of external copper cash in two ends Shang Xia 5, described inner core housing 3 upper ends are provided with installs threaded block 8, described installation threaded block 8 is suitable with shell, and described inner core housing 3 adopts exotic material to make.
When magnet 6 is changed by external magnetic field and during action, it can drive contact point 5 and with magnet 6, attracts or repel motion downward or upward, respectively with contact 4 conductings of contact point external copper cash at two ends 5 Shang Xia, thereby exports unlike signal.
Adopt structural design of the present utility model, adopt simultaneously exotic material to make inner core housing 3, described exotic material can stand 250 ° of high temperature by high energy, therefore makes the utility model can adapt to the temperature range of-60 to 250 degrees centigrade.
Referring to Fig. 2 and Fig. 3, described inner core housing 3 lower ends are provided with adjusting nut 7, in the middle of described adjusting nut 7, have the hole suitable with cylinder 9, described cylinder 9 is connected with magnet 6 after running through adjusting nut 7, by regulating the position of adjusting nut 7, change the distance of reaction of magnet 6, thereby meet different occasion demands.
Referring to Fig. 1, described shell is provided with two hold-down nuts 1.Between described hold-down nut 1, be provided with at least one pad 2.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
