Abstract
The invention discloses an optical fiber sealed adaption experiment assistant device. The optical fiber sealed adaption experiment assistant device comprises a tubular container body; a cavity capable of being filled with sealant is formed inside the container body; the upper portion of the container body is provided with a sealing cover which is connected with the container body through a fastening bolt, and the outer surface of the connecting part of the sealing cover with the container body is provided with a sealing flange; the sealing cover and the bottom plate of the container body are oppositely provided with a plurality of optical fiber positioners; an optical fiber with a part of inner and outer sheath stripped is arranged between the opposite optical fiber positioners; a sealant filling port is formed in the middle of the sealing cover. The optical fiber sealed adaption experiment assistant device is reliable in sealing performance and applicable to studying the problems of overhigh signal transmission attenuation when an optical fiber adapting device leads an optical fiber into a sealed high-pressure container as well as airtightness of the optical fiber adapting device impacted by high pressure.
Description
Technical field
The present invention relates to a kind of experimental provision, particularly relate to a kind of optical fiber seal switching experiment auxiliary device.
Background technology
Fiber core structure and fibre core material of main part determine optical fiber and in use have easy essence, non-anti-extrusion, the feature such as not shock-resistant as signal transmssion line, therefore, normally used optical fiber all arranges inside and outside protective seam and cushion to protect fibre core outside its fibre core; The setting of fibre core protective seam, for needing the optical fiber sealing introducing place, namely the gap between its inside and outside protective seam, the gap between inner protective layer and fibre core become the main leakage path after optical fiber seal.
There is provided a kind of sealing means for drawing the sealing of optical fiber in wall penetration optical fibers sealing or pipeline in Chinese patent " seal socket for wall penetration optical fibers " (patent No. 200810140722), " a kind of optical fiber airtight transfer socket " (patent No. 201110388681) instructions respectively.The light path of mode communication seals switching place that these two kinds of sealing means all adopt Fiber connection ceramic contact pin to dock, and injecting glue inside and outside ceramic contact pin is realized to the sealing of optical fibre channel.Due to present connecting fiber ceramic contact pin make and end surface grinding technique relatively perfect, the optical transport decay of packoff is little, but because ceramic contact pin effective sealing section is short, cause the impact resistance of device weak, the effective sealing time is short, only can be used for body of wall both sides or pipeline inside and outside without the seal isolation under pressure difference or the less situation of pressure difference, under closed pressure vessel inner high voltage gas impact pressure can not be applied to, introduce optical fiber.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of optical fiber seal switching experiment auxiliary device, in order to study the optical fiber transition devices hermetic seal problem that Signal transmissions decay is excessive and device is after impacting with high pressure when introducing optical fiber in closed pressure vessel.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of optical fiber seal switching experiment auxiliary device, comprise cylindrical container body, the inside of described vessel is provided with can the cavity of filling and sealing glue, described vessel top is provided with a gland bonnet, described gland bonnet to be connected with vessel by fastening bolt and the outside surface of junction is provided with seal flange, relatively with the base plate of vessel on described gland bonnet be provided with some optical fiber locators, be connected with the optical fiber of outer shield in released part between described relative optical fiber locator, in the middle of described gland bonnet, be provided with encapsulating mouth.
Further, described fluid sealant is preferably epoxy resin embedding adhesive.
The invention has the beneficial effects as follows: sealing property of the present invention is reliable, being applicable to study the optical fiber transition devices hermetic seal problem that Signal transmissions decay is excessive and device is after impacting with high pressure when introducing optical fiber in closed pressure vessel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-vessel; 2-gland bonnet; 21-fastening bolt; 22-encapsulating mouth; 23-seal flange; 3-optical fiber locator; The optical fiber of outer shield in 4-released part; 5-fluid sealant.
Embodiment
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of optical fiber seal switching experiment auxiliary device, comprise cylindrical container body 1, the inside of described vessel 1 is provided with can the cavity of filling and sealing glue 5, described vessel 1 top is provided with a gland bonnet 2, described gland bonnet 2 to be connected with vessel 1 by fastening bolt 21 and the outside surface of junction is provided with seal flange 23, relatively with the base plate of vessel 1 on described gland bonnet 2 be provided with some optical fiber locators 3, be connected with the optical fiber 4 of outer shield in released part between described relative optical fiber locator 3, in the middle of described gland bonnet 2, be provided with encapsulating mouth 22.
Described fluid sealant 5 is preferably epoxy resin embedding adhesive.
During use, between relative optical fiber locator 3, first connect the optical fiber 4 of outer shield in released part, after connection, epoxy resin sealant 5 is injected from encapsulating mouth 22, the injection process graded of epoxy resin sealant 5 completes, carry out after the fluid sealant that each injection Ying Qian once injects solidifies completely, after all epoxy resin sealants 5 solidify completely, close encapsulating mouth 22; Last with other equipment couplings, the transfer fade performance of experiment auxiliary device, data-signal transmission performance and sealing property of optical fiber seal is tested.
