Abstract
Fiber cable joint box sealing washer belongs to fiber cable joint box subassembly field. The sealing washer both ends are a fixed connection annular metallic piece all, support spacing area and intensity through the sheetmetal increase, the friction that reduces the sealing washer and extrude gland nut, the sealing washer wherein sheetmetal of one end wraps up in the sealing washer, should hold to support during the use and lean on in the downthehole terminal surface of optical cable by the shoulder, sealing washer and optical cable matched with face are the curved surface of protruding type, when the sealing washer receives the extrusion, the sealing washer warp easily, improve the sealed effect of sealing washer and optical cable, the utility model provides a prevent the impaired fiber cable joint box sealing washer of sealing washer.
Description
Technical field
This utility model belongs to fiber cable joint case assembly field, especially with a kind of cable splice closure sealing ring.
Background technology
Existing cable type connector box seals frequently with cartridge type rubber ring, its principle is, the deformation utilizing rubber realizes sealing, during use, sealing ring one end is leaned extruding by clamp nut realized deformation, owing to the friction between clamp nut end and rubber ring is bigger by optical cable shoulder inner face limited support, the other end, cause when clamp nut rotates, clamp nut end can rotate by band dynamic seal ring, and sealing ring produces friction with shoulder end face, easily causes sealing ring damage.
Utility model content
The purpose of this utility model is intended to overcome existing clamp nut clamp nut and sealing ring direct friction when compressing sealing to cause damage, it is provided that a kind of cable splice closure sealing ring preventing sealing ring impaired.
To this end, this utility model is by the following technical solutions: cable splice closure sealing ring, it is characterized in that, connection one annular sheet metal is all fixed at sealing ring two ends, increases support limit area and intensity by sheet metal, reduces the friction of sealing ring and extruding clamp nut.
As supplementing technique scheme and perfect, this utility model also includes techniques below feature.
The sheet metal of described sealing ring wherein one end is wrapped in sealing ring, and during use, this end is resisted against holes for optical cables inner face shoulder.
The face that described sealing ring matches with optical cable is the curved surface of convex, and when sealing ring is squeezed, sealing ring is easily deformed, and improves the sealing effectiveness of sealing ring and optical cable.
During use, by ring set in the box body of cable splice closure, optical cable passes in box body, one end shoulder rest of sealing ring coated metal sheet is in box body inner face, and tray interior arranges female thread, and described clamp nut is connected with screw-internal thread fit, clamp nut end shoulder is in the sheet metal of the sealing ring other end, in the pressure lower seal of clamp nut to contract, the convex curved surface of sealing ring fits tightly with optical cable, plays the effect of sealing.
Use this utility model can reach following beneficial effect: this utility model passes through clamp nut to the sheet metal active force on sealing ring, sealing ring is shunk and seals, two sheet metals on sealing ring prevent sealing ring from directly contacting with shoulder face and clamp nut, improving service life, long term seal is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, connection one annular sheet metal 2 is all fixed at sealing ring 4 two ends of the present utility model, support limit area and intensity is increased by sheet metal 2, reduce the friction of sealing ring 4 and extruding clamp nut 1, the sheet metal 2 of described sealing ring 4 wherein one end is wrapped in sealing ring 4, during use, this end is resisted against holes for optical cables inner face shoulder, the curved surface that face is convex that described sealing ring 4 matches with optical cable, when sealing ring 4 is squeezed, sealing ring 4 is easily deformed, and improves the sealing effectiveness of sealing ring 4 and optical cable.
During use, sealing ring 4 is set in the box body 3 of cable splice closure, optical cable passes in box body 3, one end shoulder rest of sealing ring 4 coated metal sheet 2 is in box body 3 inner face, and box body 3 is internal arranges female thread, and described clamp nut 1 is connected with screw-internal thread fit, clamp nut 1 end shoulder is in the sheet metal 2 of sealing ring 4 other end, in the pressure lower seal 4 of clamp nut 1 to contract, the convex curved surface of sealing ring 4 fits tightly with optical cable, plays the effect of sealing.
