Abstract
The utility model provides an optical cable sealing device, consisting of an optical cable sealing ring, a metal gasket and a connecting catch; two round through holes are arranged at the center of the cylindrical sealing ring, and two concave pits are arranged in vertical direction of the two round through holes at two sides of the cylindrical sealing ring; a trilinear opening right above the two round through holes divides the regular circle and forms a freely open-close opening; two communicating round through holes are arranged at the center of the metal gasket, and two locating pins are arranged in vertical direction of the two round through holes; the connecting catch has an oval structure and a locating pin hole corresponding to the locating pins of the metal gasket at each end respectively. When installing an optical cable, the optical cable can be bent and embedded in the sealing ring without cutting off the cable; at the same time, the sealing ring can be closed to form a whole circle, and size of the round through holes can be constricted under external force; the metal gasket extrudes the sealing ring under external force so that the sealing ring deforms and expands; then the sealing ring tightly wraps the outer surface of the optical cable, fills other space of a cable inlet, and has the sealing effect.
Description
Technical field
The utility model relates to a kind of cable sealing device, especially the packoff of using during the optical cable multiple connection.
Technical background
In the prior art, at the hermetically-sealed construction of the import and export of cable splice closure, mostly adopt artificial the twine way of rubber and the supporting use of O-ring seal of different inner diameters; Or adopt the O-ring seal of in a cable splice closure, joining many different inner diameters, and select corresponding O-ring seal to cooperate, after the heat-shrink tube pyrocondensation, seal, such O-ring seal specification is many, sealing effectiveness is bad, inconvenience is installed, and is unfavorable for the general of different size, big or small cable.Simultaneously, all must adopt when multiple connection and cut off optical cable, two optical cable heads insert in the connector box, and such packoff is installed trouble, a little less than the reliability, the time one experiences all sorts of and exposes to the weather, and will lose sealing function, can cause butt junction to get rusty, also can interrupt all communications, influence the communication effect of optical cable.
Summary of the invention
The purpose of this utility model provides the cable sealing device of a kind of easy for installation, not interrupt unit communication of when construction, good sealing effect.
For achieving the above object, the utility model adopts following technical scheme: it is by the optical cable O-ring seal, metal washer be connected catch and form, employing is opened two round tube holes at the center of cylindrical seal circle, respectively establish two pits in column sealed circle both sides and this two round tube holes vertical direction, directly over two round tube holes, will just justify and cut apart with tri linear, the outside 1/4 circle is the center with the center of circle, rotate laterally about 10 °, form one can freely openable opening, the two round intercommunicating pores that communicate are also opened at the center of metal washer, establish two register pins with two circle intercommunicating pore vertical direction, connecting the catch two ends is oval rectangular structure, and two ends are respectively opened a circular hole and cooperated with register pin on the metal washer.
Because in the technique scheme, adopted the cylindrical seal circle has been opened two round tube holes, directly over two round tube holes, will just justify and cut apart with tri linear, the outside 1/4 circle is the center with the center of circle, rotates laterally about 10 °, form one can freely openable opening, like this, can when being installed, optical cable, need not cut off optical cable as long as crooked optical cable just can embed optical cable in the O-ring seal, simultaneously, sealing trap is fashionable, forms a full circle again, and can be under external force, bring the pore size of round tube hole together, owing to adopt three folded structures, make O-ring seal play sealing effectiveness twice to water on every side, metal washer is under external force, the crush seal circle, O-ring seal distortion is expanded, pack tightly the optical cable outside surface and be filled into other spaces of cable mouth, play the sealing optical fiber cables effect, connect the middle rectangular space of catch support metal back-up ring, prevent rubber because extruding is excessive from rectangular space, influence sealing effectiveness.
Description of drawings

1 is that optical cable O-ring seal, 2 is that opening, 3 is that round tube hole, 4 is that pit, 5 is that metal washer, 6 is that round intercommunicating pore, 7 is that register pin, 8 is that ellipse connection catch, 9 is a dowel hole
Specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As accompanying drawing 1, shown in 2, it is by optical cable O-ring seal 1, metal washer 5 be connected catch 8 and form, two round tube holes 3 are opened in employing at the center of cylindrical seal circle 1, on column sealed circle 1 both sides, respectively establish two pits 4 with these two round tube holes, 3 vertical direction, directly over two round tube holes 3, will just justify and cut apart with tri linear opening 2, the outside 1/4 circle is the center with the center of circle, rotate laterally about 10 °, form one can freely openable opening, the two round intercommunicating pores 6 that communicate are also opened at the center of metal washer 5, establish two register pins 7 with circle intercommunicating pore 6 vertical direction, connecting catch 8 is ellipsoidal structure, and two ends are respectively opened a dowel hole 9 and cooperated with register pin 7 on the metal washer 5.This sample O-ring seal can be when installing optical cable, as long as crooked optical cable just can embed optical cable in the O-ring seal, need not cut off optical cable, simultaneously, sealing trap is fashionable, form a full circle again, and can bring the pore size of round tube hole together under external force, owing to adopt three folded structures, make O-ring seal play sealing effectiveness twice to water on every side, metal washer under external force, the crush seal circle expands O-ring seal distortion, pack tightly the optical cable outside surface and be filled into other spaces of cable mouth, play the sealing optical fiber cables effect, connect the middle rectangular space of catch support metal back-up ring, prevent rubber because extruding, excessive from rectangular space, influence sealing effectiveness.
