Abstract
The utility model discloses a perforated pipe, which is characterized by comprising a straight sleeve (1). A central hole (2) which is circular or in the shape of a regular pentagon is arranged in the straight sleeve (1); and five through holes which are identical in size are uniformly distributed between external circles of the central hole (2) and the straight sleeve (1). By the aid of the perforated pipe, multi-channel multiple ordered branching of a butterfly optical cable in optical communication can be realized, the defect of difficulty in installation and maintenance is overcome, and existing problems can be solved effectively.
Description
Technical field
The utility model relates to a kind of antipriming pipe, particularly a kind of antipriming pipe that plays protection, combing and difference effect when being applied to that Fiber to the home between floor and the floor.
Background technology
Information economy full-blown today, along with people constantly promote the demand of message exchange, means of communication is in transmission speed, transmission security, and have higher requirement to transport vehicle in the cost performance aspect, traditional copper cable communication is met just before great challenge, transport vehicle as a new generation---optical fiber is in the capacity of transmission, speed, security, there is huge advantage the cost performance aspect; Simultaneously, it is exposed to outdoor security, has proposed bigger challenge.
In the overall optical communication network, it is an important ingredient that light inserts part, and wherein the most complicated then is that the optical fiber that is positioned at residential building lays, so the safe antitheft of this link, installation and maintenance aspect have higher requirements.And the protection tube that existing floor optical fiber lays is the straight barrel type cylindrical tube, only is fit to once wear the cable of giving out light, be not easy to repeatedly wearing of butterfly optical cable and put, and its inner butterfly optical cable phase IPN strand, comparatively disorderly, bring inconvenience to later maintenance.
The utility model content
The purpose of this utility model is, a kind of antipriming pipe is provided.It can realize the repeatedly orderly difference of multichannel of the butterfly optical cable in the optical communication, and overcomes the shortcoming that installation and maintenance are difficult for, and can solve the problem of present existence effectively.
The technical solution of the utility model: a kind of antipriming pipe is characterized in that: comprise bobbin always, be provided with the center pit of a circle or regular pentagon in the straight bobbin, evenly divide five through holes of sizes such as being separated with between the cylindrical of center pit and straight bobbin.
In the aforesaid antipriming pipe, the outer wall of described straight bobbin be provided with shaft of bobbin always to groove.It can cooperate the outer bayonet socket of the box middle sleeve of passing by on one's way to use, and is used for preventing that the antipriming pipe rotation from causing the butterfly optical cable distortion in the location.
In the aforesaid antipriming pipe, described straight bobbin external diameter is
Compared with prior art, the utility model can realize that butterfly optical cable lays by the floor layering, satisfies the complicated requirement that residential building is laid point, the safe antitheft requirement.Antipriming pipe of the present utility model has six holes, corresponding each floor in every hole, and can wear in every hole and apply end face is the butterfly optical cable 2-4 bar of 2mm * 3mm, and through the box difference of passing by on one's way, 2-4 family resident family in just corresponding each floor.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment 1.A kind of antipriming pipe as shown in Figure 1, comprises bobbin 1 always, is provided with the center pit 2 of a regular pentagon in the straight bobbin 1, evenly divides five through holes of sizes such as being separated with between the cylindrical of center pit 2 and straight bobbin 1.The outer wall of described straight bobbin 1 is provided with the axial groove of bobbin always 1.Described straight bobbin 1 external diameter is
This antipriming pipe is applied to connect the box of passing by on one's way between each floor during FTTH registers one's residence, and butterfly optical cable 4 is worn in inside, relies on threading apparatus ferrule 5 to guide when butterfly optical cable 4 passes antipriming pipe and enters pipe hole.5 butterfly optical cables and a threading apparatus ferrule 5 can be passed in each avris hole, and 2 butterfly optical cables and a threading apparatus ferrule 5 can be passed in the inside center hole.In this way, this structure can be passed 27 butterfly optical cables 4 altogether.
Embodiment 2.A kind of antipriming pipe as shown in Figure 3, comprises bobbin 1 always, is provided with the center pit 2 of a circle in the straight bobbin 1, evenly divides five through holes of sizes such as being separated with between the cylindrical of center pit 2 and straight bobbin 1.The outer wall of described straight bobbin 1 is provided with the axial groove of bobbin always 1.Described straight bobbin 1 external diameter is
5 butterfly optical cables and a threading apparatus ferrule 5 can be passed in each avris hole, and 4 butterfly optical cables 4 and a threading apparatus ferrule 5 can be passed in the inside center hole.In this way, this structure can be passed 29 butterfly optical cables 4 altogether.
Claims (3)
1. an antipriming pipe is characterized in that: comprise bobbin (1) always, be provided with the center pit (2) of a circle or regular pentagon in the straight bobbin (1), evenly divide five through holes of sizes such as being separated with between the cylindrical of center pit (2) and straight bobbin (1).
