Description
Technical field
The present invention relates to optical fiber seal connection structure field, specifically a kind of optical fiber crosses vacuum seal structure.
Background technique
American scientist Bell in 1880（Alexander Graham Bell）And its voice signal is modulated to light by assistant
Shu Zhong, and successfully realize the wireless transmission between two buildings.This experiment is used in light beam as carrier wave for the first time
In communication, light fast-developing prelude in the field of communications has been opened.By the development in this more century, Fibre Optical Communication Technology
It has been widely used in various optical signalling transmission fields, including phone, network, television signal transmission, the spy of atmosphere, space
Survey signal transmission, the transmission etc. of optical sensing data medium.And why so can widely be applied, then it is to have benefited from its phase
To several clear superiorities possessed by other communication modes：Firstly, fiber optic communication has unrivaled transmission capacity；Secondly,
Fiber optic communication has the characteristics that decaying is low, repeater span is long；Again, the signaling security height of fiber optic communication, good confidentiality, anti-dry
It is strong to disturb ability；In addition, fiber optic communication also have it is light-weight, corrosion-resistant, convenient for being laid with, raw material resources are abundant and low in cost etc. excellent
Point.As one of a kind of signal transmission form of mainstream now, optical fiber also relates in many engineer applications, and vacuum, spy
Different atmosphere etc. also belongs to common engineering-environment.Due to the uniqueness of light conduction pattern in a fiber, so that it can not be divided
Segmentation switching.Therefore switching of the optical fiber between different spaces, can only be in such a way that whole passes through, and sealing problem therein
Just no small resistance therefore is brought to relevant engineer application at no small problem together.It is existing few on the market at present
Several optical fiber of number cross vacuum adapter, can preferably solve the problems, such as this, but wherein still have such as technical monopoly, price
The deficiencies of valuableness, installation convenience is inadequate, can only be compatible with some specific flanges, optical fiber place.
The object of the present invention is to provide a kind of optical fiber to cross vacuum seal structure for summary of the invention, to solve prior art optical fiber
Cross vacuum adapter there are the problem of
In order to achieve the above object, the technical scheme adopted by the invention is as follows：
Optical fiber crosses vacuum seal structure, it is characterised in that：Including flange, at least one perforation flange is coaxially arranged in flange
Perforation, the axial side of flange correspond to each punch position and are coaxially connected with screw respectively, and screw center is machined with same with screw
The conical socket of axis, the heavy caliber notch of conical socket are located at the one end of screw far from flange, the small-bore notch of conical socket
Perforation coaxial communication corresponding with flange, further includes the matched nut of each screw, rubber pad, the rubber pad shape and spiral shell
Shape matches in conical socket in nail, and rubber pad is coaxially assemblied in the conical socket of screw, and the axial length of rubber pad is greater than
Axial length in the conical socket at place, rubber pad center are equipped with through-hole, through-hole perforation coaxial communication corresponding with flange, institute
It states nut to be screwed on matched screw, central through hole, and the central through hole of nut and corresponding rubber is equipped in the cap of nut
The through-hole coaxial communication of rubber mat；Optical fiber sequentially passes through matched nut, rubber pad, flange, tightening nuts, and nut produces rubber pad
It is raw to squeeze to reach sealing effect.
The optical fiber crosses vacuum seal structure, it is characterised in that：Perforation, rubber pad inner via hole, nut cap in flange
The aperture of interior central through hole is all larger than or is equal to fibre diameter.
The optical fiber crosses vacuum seal structure, it is characterised in that：The rubber pad is made of soft silicon rubber.
The optical fiber crosses vacuum seal structure, it is characterised in that：When having multiple perforation in flange, by multiple perforation and often
The corresponding rubber pad inner via hole of a perforation, nut cap central through hole constitute the multichannel array method passed through for multifiber
It is blue.
The optical fiber crosses vacuum seal structure, it is characterised in that：In multichannel array flange, the diameter in channel can not
Together, with the optical fiber suitable for different-diameter.
The present invention has acquiring a certain degree of difficulty in view of optical fiber in switching, and having vacuum adapter on the market has different offices
It is sex-limited, therefore have developed a kind of optical fiber and cross vacuum seal structure, have to application of the optical fiber in some specific engineering-environments
There is important meaning.
In order to enable the optical fiber of very thin fragility nondestructively by flange, while reaching good sealing effect, spy is with common
Flange is prototype, it is transformed, and has devised a kind of special flange of bolt structure with conical socket and perforation,
In addition matched perforation nut and the soft silicone rubber pad of sealing, it is lossless across flange and excellent sealing successfully to realize optical fiber
The target of performance.
Firstly, processing the perforation of a very little on flange, aperture is usually no more than 3mm, passes freely through for optical fiber；
Secondly, the one side on the outside of the vacuum of flange, processes a screw on its periphery centered on perforation, screw center has
Funnel-shaped recesses, in addition process the matched nut of a screw, and nut cap has central through hole；
Then, to seal with soft silicon rubber as raw material, making an axle center by mold has through-hole（Aperture 0.5mm or with
Under）Rubber pad, rubber pad geomery is just matched with the conical socket among screw, and axial length is than conical socket axis
It is slightly long to depth（General long 1~3mm）,；
It is last then after optical fiber is sequentially passed through nut, rubber pad, flange hole, padded rubber pad, tightening nuts can be by tightening
The extruding generated when nut makes between rubber pad and optical fiber, generates and combine closely between rubber pad and flange, reaches the effect of sealing
Fruit.
It is worth noting that, funnel-shaped recesses and sealing rubber pad are the key in the present invention.It is different from wire, optical fiber
It is very thin and enbrittle, therefore the through-hole aperture of rubber pad can neither be less than fibre diameter（Otherwise when passing through easily
It is disconnected）, can not be too big（It is easily reduced vacuum sealing effect）.
