Embodiment
Embodiment:
As shown in Figure 1, the optical fiber mounting flange socket with sealing of the embodiment of the invention comprises mounting flange 1 and the over cap 2 that links to each other with mounting flange 1 when Optical fiber plug is not connected.
In the present embodiment, mounting flange 1 is provided with the mounting hole 12 that is used for fixing Optical fiber plug, mounting hole 12 is similar run-track shaped groove, the side of mounting hole 12 is provided with the plane of orientation 121 that is used for the Optical fiber plug that inserts is carried out located lateral, be provided with the limited step 13 that is used for the Optical fiber plug that inserts is carried out longitudinal register in the mounting hole 12, when outside Optical fiber plug docks with the embodiment of the invention, can guarantee that heart yearn is in the preposition excellent contact like this.
Be provided with the sealing gasket 4 that the end with mounting flange 1 is oppositely arranged in the over cap 2; the end of mounting flange 1 is provided with the projection 17 of sharp-pointed shape; the edge of sealing gasket 4 is provided with and projection 17 close-fitting convex closures 41; sealing gasket 4 is provided with snap ring 42; sealing gasket 4 is adhesively fixed in over cap 2 by snap ring 42, thereby can prevent that sealing gasket 4 from coming off.The projection 17 of present embodiment is taper.When the flange socket did not need to dock with external plug, over cap 3 screwed on mounting flange 1, on its inner sealing pad 4 the projection 17 of convex closure 41 and mounting flange 1 end face closely cooperate, these projection 17 sizes are minimum, about high 0.3mm.Utilize pressure (P)=pressure (F)/area (S) principle, reduce end face of flange and sealing gasket 4 contacts area can improve pressure, increase sealing, thereby realize excellent sealing.Equally, the plug inside of external fiber plug also has the rubber like cushion device, the external fiber plug because the effect that the rubber blanket of projection 17 and external fiber plug cooperates also can stop steam to be invaded, is realized the excellent sealing between plug, the socket with after flange socket of the present invention docks.
In the present embodiment; mounting flange 1 is provided with and is used for screw mounting hole 11 and the screw thread 16 that is used to be connected Optical fiber plug or over cap 2; screw thread 16 is a three-start screw; three-start screw has the three start screw line; three screw thread starting points are promptly arranged, and its pitch is three times of STRTHD, therefore when the mounting flange socket docks with external plug or over cap 3; only need screw relative STRTHD three/once all numbers can dock and put in place, so have advantage quick for installation, convenient disassembly.
There is wedge seal groove 14 at the back side of mounting flange 1, is equiped with the O type circle 2 that is used to seal in the wedge seal groove 14.Wedge seal groove 14 is the big shape in the young end, so O type circle 2 just is stuck after inserting, and can't come off.When mounting flange 1 during by screw lock, the O type circle 2 of 14 inside is compressed in the wedge seal groove, fits tightly with device panel, realized between flange and the equipment sealing.
The material of mounting flange 1 of the present invention is not limited to metal, also comprises the engineering plastics that meet the demands, and can reduce cost greatly like this.When using engineering plastics, the R angle 15 on the mounting flange 1 has the effect that strengthens the product mechanical property.The present invention is used for optical cable fixing at 3G equipment interface place and is connected, solves the quick connection of optical fiber inside and outside equipment, and the sealing that guarantees equipment when externally optical fiber does not connect, and prevents the intrusion of steam, the performance of assurance equipment.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
