Description
Technical field
The utility model relates to cable splice closure field, is specially a kind of cable splice closure cable mouth mechanical seal locking device.
Background technology
Present connector box is on the market due to environment for use difference, and the direction entering tray interior from optical cable is mainly divided into two kinds, single-ended and both-end two class formation.Both-end box body sealing means mainly adopts butyl unvulcanized rubber as encapsulant, and its shortcoming is that butyl unvulcanized rubber has autohension, and constructing operation is inconvenient, the time is long and repeat unlatching seals very difficult again and needs again to add encapsulant; Single-ended box body sealing adopts vulcanized rubber and heat-shrink tube sealing cable mouth combination sealing mode, heat-shrink tube sealing needs to add the sealing of flame heat shrink, cannot use different regions, execution conditions, state's laws regulation etc. are conditional, except the structure except above sealing means, at present just after the test of high/low temperature circulation experiment, be difficult to reach technical requirement.
Utility model content
The technical matters that the utility model solves is to provide a kind of cable splice closure cable mouth mechanical seal locking device, to solve the problem.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of cable splice closure cable mouth mechanical seal locking device, comprises the sealing of optical cable cable mouth washer, optical cable cable mouth, T-shaped rubber seal plain washer, anti-rotation plain washer, T-shaped rubber seal, tapered cup nut, reducing pipe rhombus end tooth, reducing pipe; Described optical cable cable mouth sealing catch is in one end of locking device, and the downside of optical cable cable mouth sealing catch is provided with optical cable cable mouth, and side is provided with T-shaped rubber seal plain washer, anti-rotation plain washer; The centre of described T-shaped rubber seal plain washer, anti-rotation plain washer is provided with T-shaped rubber seal and reducing pipe, and the side of reducing pipe is provided with tapered cup nut; Described reducing pipe rhombus broken teeth seals catch with optical cable cable mouth and is connected.
As preferably, described reducing pipe compresses T-shaped rubber seal end face flush end causes gas can only by inside T-shaped rubber seal, by tapered cup nut tapering, reducing pipe end tooth section diameter is diminished again, force rubber tube internal diameter tightly to push down cable outer diameter, cause sealing firmly.
As preferably, the plane of the T-shaped rubber seal that contracts is pressed between the flat surface that described optical cable cable mouth inwall increases and taper pipe, make its gas acomia from T-shaped rubber seal lateral wall leakage, have additional Plastic Flat packing ring between T-shaped rubber seal and optical cable cable mouth flat surface, prevent T-shaped rubber seal knob distortion while rotary conic pipe.
As preferably, described reducing pipe one end end tooth is many rhombus strips, and when being subject to taper external force and diminishing, end tooth can reduce toward inner side simultaneously in the same way, and the circle that the inner circle after reducing has been, without too much gap.
As preferably, described tapered cup nut is inserted in from the end tooth end of reducing pipe and after screwing, forces end tooth evenly inwardly to reduce, thus reaches casing diameter and diminish, and can meet the fixing of different optic cable diameter and sealing.
The utility model utilizes T-shaped rubber seal end surfaces to press by reducing pipe port and the circular cable mouth of screw thread and compels to seal, reducing pipe end tooth utilizes tapered cup nut to screw pressure side tooth diameter to diminish thus make optical cable and T-shaped rubber sealing tube pack tightly sealing, structure is simple, easy to use, enables optical cable fixing seal optical cable fast.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present utility model.
Fig. 2 is overall schematic of the present utility model.
Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1-2, a kind of cable splice closure cable mouth mechanical seal locking device, comprises the sealing of optical cable cable mouth washer 1, optical cable cable mouth 2, T-shaped rubber seal plain washer 3, anti-rotation plain washer 4, T-shaped rubber seal 5, tapered cup nut 6, reducing pipe rhombus end tooth 7, reducing pipe 8; Described optical cable cable mouth sealing catch 1 is in one end of locking device, and the downside of optical cable cable mouth sealing catch 1 is provided with optical cable cable mouth 2, and side is provided with T-shaped rubber seal plain washer 3, anti-rotation plain washer 4; The centre of described T-shaped rubber seal plain washer 3, anti-rotation plain washer 4 is provided with T-shaped rubber seal 5 and reducing pipe 8, and the side of reducing pipe 8 is provided with tapered cup nut 6; Described reducing pipe rhombus broken teeth 7 seals catch 1 with optical cable cable mouth and is connected.
As preferably, described reducing pipe 8 compresses T-shaped rubber seal 5 end face flush end causes gas can only by inside T-shaped rubber seal 5, by tapered cup nut 6 tapering, reducing pipe 8 end tooth section diameter is diminished again, force rubber tube internal diameter tightly to push down cable outer diameter, cause sealing firmly.
As preferably, the plane of the T-shaped rubber seal 5 that contracts is pressed between the flat surface that described optical cable cable mouth inwall increases and taper pipe, make its gas acomia from T-shaped rubber seal 5 lateral wall leakage, have additional Plastic Flat packing ring between T-shaped rubber seal 5 and optical cable cable mouth flat surface, prevent T-shaped rubber seal 5 knob distortion while rotary conic pipe.
As preferably, described reducing pipe 8 one end end tooth is many rhombus strips, and when being subject to taper external force and diminishing, end tooth can reduce toward inner side simultaneously in the same way, and the circle that the inner circle after reducing has been, without too much gap.
As preferably, described tapered cup nut 6 is inserted in from the end tooth end of reducing pipe 8 and after screwing, forces end tooth evenly inwardly to reduce, thus reaches casing diameter and diminish, and can meet the fixing of different optic cable diameter and sealing.
The utility model utilizes T-shaped rubber seal end surfaces to press by reducing pipe port and the circular cable mouth of screw thread and compels to seal, reducing pipe end tooth utilizes tapered cup nut to screw pressure side tooth diameter to diminish thus make optical cable and T-shaped rubber sealing tube pack tightly sealing, structure is simple, easy to use, enables optical cable fixing seal optical cable fast.
