Abstract
The utility model provides an optical cable joint box which can enable the joint section of an optical cable to be effectively protected and not to be affected by the outside influence and provide a good coiling and accommodating place for optical cables and optical fibers, and guarantees that the optical fibers are reasonably arrayed and not easy to mix and intertwine; and the defects that in the prior art, the protection and accommodation and the like of the optical cables and the optical fibers at the joint sections are not enough are overcome. The optical cable joint box comprises a fixation frame, a base and a joint box cover, wherein the base and the joint box cover can be clamped with each other. The fixation frame is provided with fiber accommodation discs. A plurality of single fiber in-and-out pipes and at least one multi-fiber in-and-out pipe are arranged under the fiber accommodation discs, wherein the single fiber in-and-out pipes and the multi-fiber in-and-out pipe extend out of the base and are communicated with the lower ends of the fiber accommodation discs through a connection structure. The optical cable joint box is suitable to be used in occasions where the joint section of the optical cable is protected, and the optical cable joint box has the advantages of being capable of enabling the optical fibers not to be mixed and intertwined easily, being convenient to fix, disassemble and maintain and the like.
Description
Technical field
The utility model belongs to optical cable installing area, relates in particular to a kind of cable splice closure.
Background technology
In present production, life, optical cable is very common, and optical cable is mainly to consist of light transmitting fiber, crust, filling material etc., is a kind of communication line of realizing optical signal transmission.And optical cable is as communication line, coverage distance is very long, in installation process, need to repeatedly continue, and is continuing place, need to protect, and for the long part that continues of length, also needs to coil and accommodate.Yet optical cable, optical fiber are when accommodating, coiling, due to the factor such as difference quantity is more, easily appearance mixes mutually, is wound around, and in coiling process, lacks effectively spacing, be prone to the situations such as bending is excessive, coiling radius is too small, thereby cause fiber functions impaired.
Utility model content
The utility model overcome prior art in cable connection section to the protection of optical cable, optical fiber, the deficiency that aspect is short of to some extent such as accommodate; provide a kind of cable connection section that can make to be effectively protected, not to be subject to ectocine; for optical cable, optical fiber provide good coiling, accommodate place; assurance optical fiber arrangement is reasonable, not easily damaged, to be difficult for mixing winding cable splice closure.
The utility model is achieved through the following technical solutions:
A kind of cable splice closure, comprise fixed mount and the base that can engage mutually, joint lid, described fixed mount is provided with optical fiber distribution plate, described optical fiber distribution plate below is provided with some unit cable inlet/outlet pipes, at least one many optical cable inlet/outlet pipe, outside described unit cable inlet/outlet pipe, many optical cable inlet/outlet pipe protuberate basic units, described unit cable inlet/outlet pipe, many optical cable inlet/outlet pipes are communicated with by syndeton with optical fiber distribution plate lower end.A plurality of optical fiber distribution plates can be used for coiling, accommodate different optical cables, optical fiber, and it can not mixed, and arrange rationally; Optical cable, optical fiber stretch out by optical cable inlet/outlet pipe, and joint lid can cover optical fiber distribution plate, plays a protective role.
As preferably, described syndeton is the heat-shrink tube for the protection of optical fiber, and described heat-shrink tube is set between unit cable inlet/outlet pipe, many optical cable inlet/outlet pipes and optical fiber distribution plate lower end.Utilize heat-shrink tube to protect exposed optical cable, optical fiber.
As preferably, described fixed mount is provided with strengthening core holder, and described strengthening core holder is provided with strengthening core.Optical cable can be subject to tractive force while arranging, be conventionally no more than optical cable and allow 80% of tension force, and main tractive force can be applied on the strengthening core of optical cable, prevents that optical cable is impaired.
As preferably, described connector box covers the anchor ear being provided with for fixture splice lid and base.Anchor ear can utilize screw, snap close locking, and anchor ear, for joint lid and the base of being locked, is also convenient to detachable maintaining simultaneously.
As preferably, described unit cable inlet/outlet pipe number is 6.
Therefore, the beneficial effects of the utility model are: (1) can provide good coiling, accommodate place for optical cable, optical fiber, makes it be difficult for mixing winding; (2) utilize anchor ear be locked joint lid and base, convenient fixing, is also convenient to detachable maintaining.
Accompanying drawing explanation
Fig. 1 is the utility model explosive view.
In figure: base 1, joint lid 2, optical fiber distribution plate 3, unit cable inlet/outlet pipe 4, many optical cable inlet/outlet pipes 5, strengthening core holder 6, anchor ear 7, screw 8.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of cable splice closure as shown in Figure 1, the base 1 that comprises fixed mount and can engage mutually, joint lid 2, described fixed mount is provided with optical fiber distribution plate 3, described optical fiber distribution plate 3 belows are provided with some unit cable inlet/outlet pipes 4, at least one many optical cable inlet/outlet pipe 5, outside described unit cable inlet/outlet pipe 4, many optical cable inlet/outlet pipe 5 protuberate basic units 1, described unit cable inlet/outlet pipe 4, many optical cable inlet/outlet pipes 5 are communicated with by syndeton with optical fiber distribution plate 3 lower ends.Described syndeton is the heat-shrink tube for the protection of optical fiber, and described heat-shrink tube is set between unit cable inlet/outlet pipe 4, many optical cable inlet/outlet pipes 5 and optical fiber distribution plate 3 lower ends.Utilize heat-shrink tube to protect exposed optical cable, optical fiber.Described fixed mount is provided with strengthening core holder 6, and described strengthening core holder 6 is provided with strengthening core.Optical cable can be subject to tractive force while arranging, be conventionally no more than optical cable and allow 80% of tension force, and main tractive force can be applied on the strengthening core of optical cable, prevents that optical cable is impaired.Described joint lid 2 is provided with the anchor ear 7 with base 1 for fixture splice lid 2.Anchor ear 7 can utilize the locking of screw 8, snap close, and 7 of anchor ears, for joint lid 2 and the base 1 of being locked, are also convenient to detachable maintaining simultaneously.And between joint lid 2 and base 1, seal can also be set.Described unit cable inlet/outlet pipe 4 numbers are 6.
