Description
Technical field
The utility model relates to optical fiber more particularly to optical fiber splicing devices.
Background technique
Optical fiber requires to accomplish dustproof and waterproof in outdoor attachment device, and wherein waterproof performance more attracts people's attention.
CN106405769A discloses a kind of outer waterproof connecting device of fiber chamber, including main casing, main casing head end are equipped with dust cap, main casing
Cover locking shell and dust cap locking, are equipped with sealing on body between main casing and dust cap and between locking shell and main casing
Circle, main casing tail portion are successively arranged sealing cylinder, shrink clip and tail swivel nut, and sealing ring is equipped between tail swivel nut and main casing.
It is designed on the contraction clip, sealing cylinder and tail swivel nut for the perforative cable hole of cable；The sealing cylinder is cylindric
Structure, and cylindrical wall is equipped with a section, and cable is penetrated cable hole to facilitate；When connection, the cable pass through tail swivel nut,
The cable hole for sealing cylinder and shrinking on clip gradually screws locking shell to front end, and keeps grasping item inside by inclined surface
Sealing cylinder is received forward simultaneously, to lock cable；The sealing column of above structure tail portion is shorter than shrinking clip, because of sealing cylinder
Plastic elastomeric, can and shrink clip it is soft or hard cooperation to seal, but shrink clip only leaned on the waterproof of main casing together with it is close
Seal is completed, and is threadedly coupled between tail swivel nut and sealing cylinder, waterproof ability is difficult to reach IP68 waterproofing grade.This
Outside, the structure tensile strength is also insufficient.
Summary of the invention
The purpose of this utility model is to solve the defect of the prior art, provides a kind of outer waterproof connecting device of fiber chamber.This
Utility model waterproof performance is good, easy for assemble or unload.
Purpose of the utility model is realized as follows: the outer waterproof connecting device of fiber chamber, it includes dust cap, main casing
Body, the sealing cylinder of locking shell and tail portion, contraction clip and tail swivel nut, 20-22 millimeters of normal direction length of the contraction clip,
The sealing cylinder, which is filled in, to be shunk in clip, and is equipped with flange close to main casing body end, is equipped with inside main casing and the flange is corresponding
Baffle ring, when completing assembly, flange and baffle ring are in close contact to realize sealing, and waterproofing grade reaches IP68.
The fiber chamber outer waterproof connecting device has one group of tread plate on the dust cap excircle uniformly at intervals.
The fiber chamber outer waterproof connecting device has one group to be arranged radially on the excircle of the tail swivel nut uniformly at intervals
Raised line.
The outer waterproof connecting device of the fiber chamber, the locking shell is the sleeve of a both ends open, open at one end
It is consistent with the size of dust cap, other end opening inside diameter and main casing major diameter fit, and be spaced on the excircle of the another side
It is evenly equipped with one group of anti-skidding raised line.
The utility model is characterized by, and sealing column is plastic elastomeric, when it, which is filled in, shrinks clip, close to main casing
The flange at end may act as sealing ring, and due to being integrally formed with sealing column, compared with the waterproof ability that sealing ring can greatly improve tail portion,
Further, integrally formed retaining ring is set in main casing, can be fitted closely with flange, water is avoided to enter main casing influence
Internal optical fiber, the utility model are placed 1 month by underwater 3 meters, are not intake still, waterproofing grade is more than wanting for IP68
It asks.Furthermore non-skid feature has all been done on dust cap and tail swivel nut, so that dismounting is more convenient freely.
Detailed description of the invention
Fig. 1 is the utility model section figure；
Fig. 2 is the explosive view of the utility model.
Specific embodiment
Embodiment 1:
As depicted in figs. 1 and 2, the outer waterproof connecting device of the utility model fiber chamber, it include dust cap 1, main casing 2,
It locks the sealing cylinder 4 of shell 3 and tail portion, shrink clip 5 and tail swivel nut 6, the contraction clip normal direction length L is 20-22
Millimeter, the sealing cylinder 4, which is filled in, to be shunk in clip 5, and is equipped with flange 8 close to main casing body end, is equipped with and is somebody's turn to do inside main casing
The corresponding baffle ring 7 of flange, when completing assembly, flange and baffle ring are in close contact to realize sealing, can more effectively lock cable,
The stretching resistance and outstanding waterproof ability, waterproofing grade for making it have 130 newton or more are more than IP68.
There is one group of tread plate 8 on the dust cap excircle uniformly at intervals, which makes user more easily
Unscrew dust cap；
There is one group of raised line being arranged radially on the excircle of the tail swivel nut uniformly at intervals, which makes user
The tail swivel nut for locking or unscrewing tail portion is lighter.
The locking shell is the sleeve of a both ends open, and open at one end consistent with the size of dust cap, the other end is opened
Mouth internal diameter and main casing major diameter fit, and have one group of anti-skidding raised line and dust cap on the excircle of the another side uniformly at intervals
Cooperation can gently uncage mutually tight or unscrew.
Above-described embodiment is only to illustrate used in the utility model, and should not be understood as the limit to the utility model claims
System.Any deformation and replacement made in the spirit of claim to the utility model, falls within the power of the utility model
The claimed range of benefit.
