The movable side output port
Technical field
The utility model relates to the optical fiber cabling channel structure of using in the various types of communication machine room of the communications field, and (claim again: optical fiber optimum management system), a kind of side direction that can install flexibly that is specifically related to optical fiber cabling conduit is into and out of fine mouth structure.
Background technology
In the optical fiber communication machine room, the optical fiber conduit (below be referred to as: use optical fiber optimum management system) has brought great benefit to optical fiber wiring, management and protection undoubtedly.Yet layout, cabling mode and the path of optical fiber optimum management system should be determined according to communications device locations such as place, space and fibre distribution frames.Optical cable laying is behind machine room, and optical fiber is arranged into communication equipment tops such as fibre distribution frame along main channel and row conduit cabling, then by being connected with communication equipment such as fibre distribution frame into and out of fine mouthful.
Optical fiber optimum management system generally designs at the communications equipment room first stage of construction, because this moment, communication equipment such as fibre distribution frame was not in place as yet, therefore, can only be constructed by planning in the confirmable fiber mouth of part position in the construction and installation, often adopt the fiber mouth structure that to install flexibly for some fiber mouths that need change.In addition, after optical fiber optimum management system installed, along with the continuous development of communication service, the laying of optical fiber in conduit also increased gradually, and be regular, repeatedly lay finely down aperiodically, even to put in order the optical fiber that part is completed out again sometimes and lay.Therefore, the fiber mouth structure that needs a kind of flexible installation too.
In order to satisfy the flexible and changeable needs in fiber mouth position in the above-mentioned optical fiber optimum management system, the applicant proposes patent application to State Intellectual Property Office, and in bulletin mandate on January 1st, 2003, its name is called " conduit ejects fine structure ", and the patent No. is 02219359.6.This patent is a kind of top fiber mouth structure of optical fiber conduit, is characterized in: 1, the fiber mouth structure adopts and to hang fixed form and be installed in by the straight-through conduit, and fiber mouth position is flexible; 2, " Y " type conduit can adapt in the straight-through conduit from the optical fiber of different directions, and it is convenient to lay; 3, can guarantee that optical fiber satisfies the radius of curvature requirement in the fiber conduit.Popularization and use along with optical fiber optimum management system also expose some problems but in actual applications.Wherein, the one,, this fiber mouth output quantity is few, can't satisfy the needs that patch cord, jumping fiber quantity sharply increase; The 2nd,, thisly eject fine structure owing to adopt the fiber channels designs upwards cross, oneself height is big, when mounted since the restriction of headroom and size cause and can't install and use.
Summary of the invention
The purpose of this utility model provides and a kind ofly setting height(from bottom) is required low, and output quantity is big, and can be flexibly, the movable side output port of convenient installation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of movable side output port, comprise output groove and side hanging ear structure, described output groove is the conduit that turns to of an entire section structure, this turns to conduit to be made up of stem, middle part and afterbody, stem is a horizontal straight section of outwards drawing from straight-through conduit side, and the middle part is a bend section that is bent downwardly transition, and afterbody is a vertical straight section down; Side hanging ear is " ∩ " side mounting hook, is somebody's turn to do the stem both sides that " ∩ " side mounting hook is located at output groove respectively, and cooperates formation side mounting structure with the two side of straight-through conduit side fiber indentation, there.
The related content of technique scheme is explained as follows:
1, in the such scheme, in order to make optical fiber from straight-through level and smooth the carrying out the transition to the side output groove of conduit, can be provided with pedal on the base plate of the horizontal straight section inlet of output groove stem, this pedal extends in straight-through conduit, and forms a changeover portion in straight-through conduit bottom.
2, in the such scheme, described output groove is outwards crossed by stem, after the arc transition of middle part, is stretched by tail down.
3, in the such scheme, in order to block optical fiber in case optical fiber skid off outside the output groove, can output groove afterbody straight section on the open side of lateral surface, baffle plate is set, baffle plate is connected by the set special-shaped boss of bayonet socket and open side end.
4, in the such scheme, in order better to escort optical fiber to fibre distribution frame, can be provided with the fiber horn mouth at the lower port place of output groove afterbody straight section, the fiber horn mouth is fixedlyed connected with the lower port of output groove afterbody straight section.Also can be provided with corrugated pipe connector and corresponding bellows at the lower port place of output groove afterbody straight section, bellows is connected on the corrugated pipe connector, and corrugated pipe connector is fixedlyed connected with the lower port of output groove afterbody straight section.
5, in the such scheme, for side output port being fixed on reliably straight-through conduit one side, the bolt slot on the corresponding straight-through conduit lateral wall of described " ∩ " side mounting hook is provided with holddown groove, and bolt slot and holddown groove are bolted to connection.
6, in the such scheme, for side output port being fixed on reliably straight-through conduit one side, described output groove bottom is provided with bolt slot, and this bolt slot is connected by connecting plate and bolt with the bolt slot of straight-through conduit bottom.
Principle of the present utility model is: at the other downward conduit that turns to that is provided with of straight-through conduit, to turn to the conduit stem to be suspended on the sidewall of straight-through conduit with the side hanging ear structure, and fix by fixture, this turns to the stem of conduit outwards to draw from straight-through conduit side, form the rear portion of downward extension through middle part bend transition, form a kind of side direction that can install flexibly into and out of fine mouth structure with this.During use, just can conveniently overlap side output port as long as on the sidewall of straight-through conduit, offer a fiber breach.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model can directly be mounted on straight-through conduit side, ejects fine structure with existing conduit and compares setting height(from bottom) low (setting height(from bottom) and straight-through conduit maintain an equal level), is not subjected to the restriction of setting height(from bottom).
2, the utility model can be accomplished and straight-through conduit cross sectional shape and big or small consistent, therefore can provide maximum output quantity.
3, the utility model does not take the space of straight-through conduit itself, and the installation site is flexible, is particularly suitable for the flexible and changeable needs in fiber mouth position in the optical fiber optimum management system.
