Description
Technical field
The utility model belongs to the box body packoff, and especially to advance cable mouth novel sealing structure relevant with a kind of connector box optical cable.
Background technology
Cable splice closure is the equipment that continues that a kind of optical cable broken end connects or branch connects, the cable splice closure box body is provided with the hole and enters the cable hole as optical cable, optical cable is positioned at box body and advances the laggard cable mouth of cable mouth and have the space, these spaces need seal, at present, materials such as most employing glue seal, and such sealing means optical cable dismounting inconvenience also damages box body easily during dismounting.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is exactly the defective of infringement box body easily will overcome existing cable splice closure optical cable and advance dismounting inconvenience that cable mouth hermetically-sealed construction exists, dismounting the time, and the connector box optical cable that provides a kind of good sealing effect, easy accessibility can not damage box body again advances cable mouth novel sealing structure.For this reason, the utility model is by the following technical solutions:
The connector box optical cable advances cable mouth novel sealing structure, comprise the box body that is provided with the optical cable through hole, be characterized in: described optical cable advances cable mouth hermetically-sealed construction and comprises that also the optical cable with cylindrical hollow inner chamber advances the cable cover, the gland nut of hollow and the O-ring seal of hollow, optical cable advances that cable cover is connected with box body and is the bottom with the box wall that is provided with the optical cable through hole, optical cable advances cable cover intracavity diameter greater than described optical cable through-hole diameter, O-ring seal is inlaid in optical cable and advances in the cable cover inner chamber, optical cable advances cable cover internal chamber wall and is provided with screw thread, the gland nut outer wall is provided with optical cable and advances the corresponding screw thread of screw thread on the cable cover internal chamber wall, the gland nut spinning is advanced cable cover inner chamber in optical cable, and the gland nut end face is pressed against the end face of O-ring seal.
When the utility model uses, optical cable penetrates from the optical cable through hole of box body, pass from the inner chamber of O-ring seal and gland nut respectively and enter box body inside, have the space between optical cable and the O-ring seal, gland nut screws in optical cable and advances the cable cover, and O-ring seal is pushed, because O-ring seal adopts elastomeric material to make, under the extruding of gland nut, produce distortion, O-ring seal and optical cable are entered the space that cable overlaps between inner chamber, O-ring seal and the optical cable fill up, play sealing function; If desired optical cable is pulled down from connector box,, made O-ring seal reply original shape as long as gland nut is unscrewed, the space that comes into existence again between optical cable and the O-ring seal, optical cable can freely be pulled down.
As the further of technique scheme improved and replenish, the utility model also has following additional technical feature:
Be provided with the packing ring of hollow between described O-ring seal and the gland nut, packing ring two ends end face joins with O-ring seal end face and gland nut end face respectively, can form better squeezing action to O-ring seal.
It is suitable that the external diameter of described O-ring seal and packing ring and optical cable advance cable cover intracavity diameter, and the space that O-ring seal and optical cable are advanced between the cable cover inner chamber is as far as possible little, plays better sealing effectiveness.
Described O-ring seal inner chamber is the setting-in inner seal ring again, adapts to the sealing optical fiber cables of various diameters, and also can strengthen sealing effectiveness.
Use the utility model can reach following beneficial effect: can make things convenient for and fast optical cable be advanced the cable mouth at box body and seal, the easy accessibility of optical cable can not damage box body during dismounting simultaneously; Gland nut spinning stroke is long during sealing, makes the O-ring seal degree of deformation big, good sealing effect.
Description of drawings
Fig. 1 is the structural representation of the utility model decomposing state.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises that the optical cable with cylindrical hollow inner chamber advances cable cover 2, the O-ring seal 6 of hollow, the packing ring 4 of hollow and the gland nut 3 of hollow, optical cable advances that cable cover 2 is connected with box body 1 and is the bottom with the box wall that is provided with the optical cable through hole, optical cable advances cable and overlaps 2 intracavity diameters greater than described optical cable through-hole diameter, O-ring seal 6 is inlaid in optical cable and advances cable and overlap in 2 inner chambers, optical cable advances cable and overlaps 2 internal chamber walls and be provided with screw thread, gland nut 3 outer walls are provided with and advance cable with optical cable and overlap the corresponding screw thread of screw thread on 2 internal chamber walls, gland nut 3 spinnings are advanced cable in optical cable and are overlapped 2 inner chambers, packing ring 4 is arranged between O-ring seal 6 and the gland nut 3, packing ring 4 two ends end faces join with the end face of O-ring seal 6 and the end face of gland nut 3 respectively, and the diameter that the external diameter of O-ring seal 6 and packing ring 4 and optical cable advance cable cover 2 is suitable.Be to increase the scope of application of optic cable diameter and strengthen sealing effectiveness, can also be in O-ring seal 6 according to different optic cable diameter needs setting-in inner seal ring 5 again.
When the utility model uses, optical cable penetrates from the optical cable through hole of box body, pass from the inner chamber of O-ring seal 6, packing ring 4 and gland nut 3 respectively and enter box body inside, have the space between optical cable and the O-ring seal 6, gland nut 3 screw-in optical cables advance cable and overlap 2 inner chambers, and O-ring seal 6 is pushed, because O-ring seal 6 adopts elastomeric material to make, under the extruding of gland nut 3, produce distortion, O-ring seal 6 and optical cable are entered the space that cable overlaps between 2 inner chambers, O-ring seal 6 and the optical cable fill up, play sealing function; If desired optical cable is pulled down from connector box,, made O-ring seal 6 reply original shape as long as gland nut 3 is unscrewed, the space that comes into existence again between optical cable and the O-ring seal 6, optical cable can freely be pulled down.
