Abstract
The invention discloses a mechanical sealing and locking device for a cable opening of a fiber cable splice closure. A fiber cable opening sealing stop sheet is arranged at one end of the mechanical sealing and locking device, a fiber cable opening is formed in the lower side of the fiber cable opening sealing stop sheet, and a T-shaped rubber sealing ring flat washer and a rotating-preventing flat washer are arranged on one side of the fiber cable opening sealing stop sheet. A T-shaped rubber sealing ring and a reduction circular tube are arranged in the middles of the T-shaped rubber sealing ring flat washer and the rotating-preventing flat washer, and a conical nut is arranged on one side of the reduction circular tube. Rhombus end teeth of the reduction circular tube are connected with the fiber cable opening sealing stop sheet. According to the mechanical sealing and locking device, an end opening of the reduction circular tube and the thread circular cable opening are sealed through the end face of a T-shaped rubber sealing tube in a tightly-pressed mode, the end teeth of the reduction circular tube are tightly pressed by tightening the conical nut to enable the diameter of the end teeth to be decreased, and therefore a fiber cable and the T-shaped rubber sealing tube are tightly wrapped and sealed; the mechanical sealing and locking device is simple in structure and convenient to use, and the fiber cable can be rapidly fixed and sealed.
Description
Technical field
The present invention relates to cable splice closure field, be 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 that enters box body inside from optical cable is mainly divided into two kinds, single-ended and both-end two class formations.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 inconvenience, time are grown and repeat to open and seals very difficult again and need to again add encapsulant; Single-ended box body sealing adopts vulcanized rubber and heat-shrink tube sealing cable mouth combination sealing mode, heat-shrink tube sealing need to add the sealing of flame heat shrink, to conditional cannot uses such as different regions, execution conditions, state's laws regulations, structure except above sealing means, at present just after high low temperature circulation experiment is tested, be difficult to reach technical requirement.
Summary of the invention
Technical matters solved by the invention is to provide a kind of cable splice closure cable mouth mechanical seal locking device, to address the above problem.
Technical matters solved by the invention realizes by the following technical solutions:
A kind of cable splice closure cable mouth mechanical seal locking device, comprises optical cable cable mouth sealing 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 a 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 a side of reducing pipe is provided with tapered cup nut; Described reducing pipe rhombus broken teeth is connected with optical cable cable mouth sealing catch.
As preferably, described reducing pipe compresses T-shaped rubber seal end face flush end causes the gas can only be by T-shaped rubber seal inner side, 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, between the flat surface that described optical cable cable mouth inwall increases and taper pipe, press the plane of the T-shaped rubber seal that contracts, make its gas acomia from T-shaped rubber seal lateral wall leakage, between T-shaped rubber seal and optical cable cable mouth flat surface, have additional Plastic Flat packing ring, prevent T-shaped rubber seal knob distortion in rotary conic pipe.
As preferably, described reducing pipe one end end tooth is many rhombus strips, and in the time being subject to taper external force and diminishing, end tooth can dwindle toward inner side simultaneously in the same way, and inner circle after the dwindling circle that has been, without too much gap.
As preferably, described tapered cup nut, from the end tooth end of reducing pipe is inserted in and screws, forces end tooth evenly inwardly to dwindle, and diminishes thereby reach casing diameter, can meet the fixing and sealing of different optic cable diameters.
The present invention 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, thereby reducing pipe end tooth utilizes tapered cup nut to screw pressure side tooth diameter to diminish and makes optical cable and T-shaped rubber sealing tube pack tightly sealing, simple in structure, easy to use, make optical cable fixing seal optical cable fast.
Brief description of the drawings
