Description
Technical field
The utility model relates to automatic detection field, especially a kind of protective case close to switch.
Background technique
It is a kind of without carrying out mechanically direct contact and manipulable position switch with moving component close to switch, works as object
When body is close to the sensitive surface of switch to operating distance, switch motion can be made by not needing Mechanical Contact and any pressure of application.It
The characteristic of existing travel switch, microswitch, while there are sensing capabilities, and reliable in action, performance is stablized, and frequency response is fast,
Application life is long, and strong antijamming capability etc. simultaneously has the characteristics that waterproof, shockproof, corrosion-resistant.
Close to switch as a kind of electrical component for being likely to installation in each position of equipment, also there are many deficiencies.
One is element itself be it is very fragile, load impacting can not be received, even slight collision is also possible to cause element
Damage, the second is requiring to installation site, due to itself dimensional problem, the position thicker to some equipment wall thickness is difficult
Installation, the third is in the case where there is strong signal disturbed condition, it can be abnormal close to switch work.
Utility model content
To solve the above problems, the utility model disclose it is a kind of close to switch protection set, structure is simple, it is easy for installation,
Energy effective protection does not receive interference close to switch.
The utility model the specific technical proposal is: it is a kind of close to switch protection set, the protective case main body is sleeve,
Barrel forward end offers through-hole, and through-hole fixes close open for installing close switch and locking nut respectively inside and outside sleeve
It closes；The barrel bore diameter is greater than locking nut outer diameter；The through-hole diameter is greater than close to switch diameter, is less than locking
Nut outer diameter；The sleeve rear end portion is set as flange face, and protective case is fixed on equipment by connection bolt group by flange face
On.
Further, the length sleeve t is determined according to equipment wall thickness.
Further, the barrel forward end is provided with chamfering.
Further, the sleeve material is metal or plating lead metal.
Compared with prior art, the utility model has the following beneficial effects: utility model device close to switch by that will put
It sets in sleeve, so that protective case will not be damage close to switch when receiving slight impact, and since length sleeve is according to equipment
Wall thickness design, allowing can be installed close to switch at the thicker position of equipment wall thickness, while protecting that sleeve additionally uses can be effective
The plating aluminum metal for shielding strong signal interference protects the signal close to switch.

Specific embodiment
The utility model is further described through with reference to the accompanying drawings of the specification.
As shown in fig. 1 to fig. 4, a kind of close to switch protection set, the main body of protective case 1 is sleeve 12, and 12 front end of sleeve is opened
Equipped with through-hole, it is mounted in through-hole close to switch 3, mating sleeve 12 will be approached with inside and outside two locking nuts 2 from inside and outside respectively
Switch 3 is fixed.In order to preferably install nut, it is desirable that through-hole diameter is greater than close to 3 diameter of switch and is less than outside locking nut 2
Diameter when installing in this way, is exposed to external one close to switch 3 and through-hole does not have a gap, and the locking nut 2 in sleeve 12
It is not easily susceptible to external environment interference, just in case external nut loosens, the locking nut 2 in sleeve 12 is also capable of fixing close to switch 3.
12 intracavity diameter of sleeve is greater than 2 outer diameter of locking nut simultaneously, protrudes into the locking screw tightened in sleeve 12 also for convenient for tool
It is female.And 12 rear end of sleeve is set as flange face 11, protective case 1 is fixed on equipment 4 by connection bolt group 5 by flange face 11
On.
In order to use the protective case of the utility model in various kinds of equipment, by 12 length t of sleeve according to wanting installation place
4 wall thickness of equipment design, flexibility and changeability.
In order to shield strong signal interference, select metal or lead plating metal production sleeve 12 to shield external signal interference.
In use, installation through-hole first is opened up in the corresponding installation site of equipment 4, the protective case 1 that will be made according to 4 wall thickness of equipment
It is put into and (should first fix proximity switch 3 in protective case 1), by connecting 5 mounting flange face 11 of bolt group for protective case 1
It fixes on the device 4.In order to install convenience, chamfering 13 can be arranged in 12 front end of sleeve, so that entire protective case 1 is more beautiful
See, will not install again in scratch staff.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
