Description

A kind of communications optical cable of composite construction and cable porous protection tube pipe joint

Technical field

The utility model relates to pipe joint, is specifically related to the pipe joint of a kind of communications optical cable and cable porous protection tube.

Background technology

In communications optical cable and cable installing structure, the communications optical cable of composite material and cable protection pipe have remedied tubing deficiencies such as steel pipe, cast iron pipe, pipe of concrete, asbestos pipe, become a kind of product that extensively uses gradually in the communications field.The communications optical cable of improved composite construction and cable protection pipe have firm smooth material outward; as fiberglass, plastic-coated steel, coating steel pipe and PE pipe, HDPE pipe etc.; inside has adopted cheap PVC and PE material to cut apart according to porous again; favorable mechanical performance and the high advantage of inner space utilance have been taken into account; the cost performance height; effectively improved project quality and efficient, reduced cost, in engineering, obtained using.

Existing communication optical cable and cable protection pipe joint arrangement have three kinds of forms substantially:

First kind of mode is the plastic-coated steel joint, and it adopts the form of being small at both ends and big in the middle, with two most of cover plastic-coated steel, utilize the little caliber in the joint to position, integral body is coated with moulding material and constitutes the cost height for steel construction adds, weight is big, anticorrosion theftproof performance is undesirable, and inner hollow fully, when many optical cables pass, because deadweight makes optical cable concentrate on the pipe lower half circle, stir easily together, cause the poling difficulty, plot ratio is limited;

The second way is supporting plastic cement pipe pillow of fiberglass and rubber seal, adopts the other pipe microcephaly's of typhon muzzle of one of frp cable protective pipe or communication tube mode, and socket joint connects, and cooperates plastic cement pipe pillow and the construction of rubber seal location.This connected mode advantage is bayonet joint, good mechanical property, easy construction, the coupling part was single macropore in but major defect still was to manage, when passing, stir easily together by many cables, and because optical cable conduct oneself with dignity when length is very long influence causes to bottom accumulation, make plot ratio very low, be difficult to satisfy the needs that many optical cables pass through simultaneously;

The third connected mode is porous (comprising honeycomb duct, the plum blossom pipe) connected mode of PVC or PE material; it is by protecting protecting pipe to be connected with the homogeneity that porous PVC, PE material communications optical cable cable protection pipe outer wall are fitted; there is tongue protecting pipe inside as positioner; socket and spigot type is installed; light weight, low price, easy construction, the space availability ratio height.But,, influenced engineering safety because the bad mechanical property of PVC, PE material self is very easy destroyed in the construction.

The utility model content

The utility model purpose is the deficiency at the prior art existence; propose a kind of communications optical cable and cable porous protection tube pipe joint of composite construction, guaranteeing under the easy socket and spigot type form of construction work prerequisite, when improving porous protection tube mechanical strength; take into account cubical content, improve cost performance.

The technical solution of the utility model is as follows:

A kind of communications optical cable of composite construction and cable porous protection tube pipe joint, it is made of with outer containment vessel is compound interior connector; Described outer containment vessel is the pipe of fiberglass, plastic-coated steel, coating steel pipe, PE or HDPE material, and interior connector is fixed in wherein; Connector is the antipriming pipe connector structure of PVC or PE material in described; the outer shape of the shape of the endoporus of interior connector and connected lattice-shaped, plum blossom shape or cellular porous pipe is agreed with fully; according to engineering demand, can connect communications optical cable or cable protection pipes such as honeycomb tubular type, plum blossom tubular type, grid tubular type.

Further, the centre position of connector is provided with the locating ring of a circle radial protrusion in described, so that two communication holey fiber optic cable cable protection pipe connects the location.

The utility model is formed by two parts: adopt the protection part of hollow firm smooth material pipe (as fiberglass, be coated with plastic-steel, galvanized steel and PE, HDPE etc.) as the outside; employing is used to pass the porous PVC of communications optical cable or cable or PE pipe (containing honeycomb duct, plum blossom pipe) joint as interior coupling part, be built into thus outer have the solid shell protection, in the fiber optic cable protection tube joint of loose structure is arranged.The firm smooth material pipe of overcoat has favorable mechanical performance and chemical stability; the intensity and the corrosion resistance of compound porous protection tube joint have been guaranteed; existing P VC or PE material antipriming pipe joint style are adopted in connection in the pipe; make joint than whole employing outer tube materials (as fiberglass, be coated with plastic-steel, galvanized steel and HDPE etc.) like this; greatly reduce cost, and guaranteed enough cubical contents.Under the situation that many optical cables of needs pass through simultaneously, it can substitute original coupling, cast iron pipe joint, PVC or (PE) honeycomb duct joint, plastic-coated steel joint, the solidness requirement of can either satisfy the street pipeline, crossing complicated construction environment such as car pipeline, load-bearing road pipeline, can guarantee enough inner capacitiess again, both combinations, with low cost, easy construction, the cost performance height.
