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, and a T-shaped rubber sealing ring flat washer, a rotating-preventing flat washer, a T-shaped rubber sealing ring and a reduction circular tube are sequentially arranged in the fiber cable opening sealing stop sheet. A conical nut is arranged on the side, provided with rhombus end teeth, of the reduction circular tube. Rhombus end teeth of the reduction circular tube are connected with the conical nut. A fiber cable opening sealing stop sheet is arranged between the rhombus end teeth of the reduction circular tube and the conical nut. 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, specially a kind of cable splice closure cable mouth mechanical seal locking device.
Background technology
Due to use environment difference, the direction entering tray interior from optical cable is broadly divided into two to connector box on the market now
Kind, single-ended and both-end two class formation.Both-end box body sealing means mainly adopt butyl unvulcanized rubber as encapsulant, and it lacks
Point is that butyl unvulcanized rubber has an autohension, constructing operation inconvenience, time length and repeat to open seal again extremely difficult and
Need to add again encapsulant；Single-ended box body sealing adopts vulcanite and pyrocondensation seal of tube cable mouth combination sealing mode, heat
The draw sealing need flame enrichment flame heat shrink seal, conditional to different regions, execution conditions, state's laws regulation etc. cannot
Use, the structure in addition to above sealing means, at present just after the test of high/low temperature circulation experiment, be extremely difficult to technical requirements.
Content of the invention
Technical problem solved by the invention is to provide a kind of cable splice closure cable mouth mechanical seal locking device, to solve
Certainly the problems referred to above.
Technical problem solved by the invention employs the following technical solutions to realize:
A kind of cable splice closure cable mouth mechanical seal locking device, including optical cable cable mouth sealing washer, optical cable cable mouth, t type
Rubber seal plain washer, anti-rotation plain washer, t type rubber seal, tapered cup nut, reducing pipe rhombus end tooth, reducing pipe,

It is provided with optical cable cable mouth sealing catch between tooth and tapered cup nut.
Preferably, described reducing pipe compression t type rubber seal end face flush end causes gas can only pass through t type rubber
Inside sealing ring, then so that reducing pipe end tooth section diameter is diminished by tapered cup nut taper, force rubber bore tightly to press
Live cable outer diameter, cause sealing firmly.
Preferably, pressing contracting t type rubber seal between the flat surface of described optical cable cable mouth inwall increase and taper pipe
The plane of circle is so as to gas is no sent out from the leakage of t type rubber seal lateral wall, t type rubber seal and optical cable cable mouth flat surface
Between have additional Plastic Flat packing ring, prevent while rotary conic pipe the deformation of t type rubber seal knob.
Preferably, described reducing pipe one end end tooth is a plurality of rhombus strip, when by taper external force change hour, end tooth
Can reduce toward inner side in the same direction simultaneously, and the inner circle after reducing is the circle completing, no excessive gap.
Preferably, described tapered cup nut, after the end tooth end of reducing pipe is inserted in and is screwed, forces end tooth uniformly inside
Reducing, fixation and the sealing of different optic cable diameters thus reach casing diameter diminishing, can be met.
The present invention is pressed using t type rubber seal end surfaces and is compeled to carry out by reducing pipe port and screw thread circle cable mouth
Sealing, reducing pipe end tooth screws pressure side tooth diameter using tapered cup nut and diminishes so that optical cable and t type rubber sealing tube
Pack tightly sealing, structure is simple, easy to use, enable the quick fixing seal optical cable of optical cable.
