Abstract
The utility model discloses an optical cable deconcentrator, which comprises a box body, wherein the box body is provided with an inlet for a main optical cable and outlets for various branch optical cables; the inlet for the main optical cable and the outlets for the various branch optical cables are respectively and irrotationally provided with a crimp sleeve used for fixing the main optical cable and the various branch optical cables. By adopting the structure, the optical cable deconcentrator of the utility model fixes the main optical cable and the various branch optical cables through the crimp sleeves; the connection is stable and firm; the irrotational assembly of the crimp sleeves can guarantee that the main optical cable and the branch optical cables do not generate rotational friction in the use, the stable transmission of the optical cables is ensured and the service life of the optical cables is prolonged.
Description
Technical field
The utility model relates to the optical fiber transmission technique field, relates to a kind of deconcentrator that uses in the optical fiber transmission technique specifically.
Background technology
Optical cable is to be combined by multifiber, in use, need by deconcentrator with each single-core fiber separately connect different receiving elements respectively.A kind of deconcentrator that is widely used at present as shown in Figure 1, the separated time cover 2 that it comprises the back cover 3 that is used for plug-in mounting multicore main cable 4 and is used for plug-in mounting list core branch optical fiber 1, back cover 3 is inserted into the rear end of separated time cover 2, is filled with in the cavity that forms between separated time cover 2 and back cover 3 and solidifies adhesive 5.This deconcentrator employing curing adhesive fixes the optical fiber in the deconcentrator; not only production efficiency is lower for it; need the extra setting time of solidifying adhesive that increases; and in use, reason such as expand with heat and contract with cold breaks away from because of causing optical fiber and adhesive easily; fixing not firm; optical fiber can rotate in deconcentrator; optical fiber and separated time cover inner hole wall is rubbed; thereby damage the external protection of optical fiber; influence the transmission performance of optical fiber; when serious, even the excessive phenomenon of rupture that consequently takes place of optic fibre turning can take place.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of production efficiency height is provided, and optical fiber is fixed, the deconcentrator that is difficult for rotating.
The technical solution of the utility model is: a kind of optical cable deconcentrator, comprise box body, box body is provided with main cable access port and each branch optical fiber outlet, and the outlet of described main cable access port and each branch optical fiber is respectively arranged with the pressure welding case that is used for fixing main cable and each branch optical fiber ends that spinning joins and only revolves structure.
The outlet of described main cable access port and each branch optical fiber is respectively arranged with the pressure welding case that is used for fixing main cable and each branch optical fiber.
The outlet of described main cable access port and each branch optical fiber is respectively the groove that is opened on the end face of box body two ends, and described pressure welding case ends spinning and fits in described each groove.
Described box body is provided with lid, and box body and lid are connected and fixed by screw.
Also be equipped with the heat-shrink tube that is used to protect optical cable in the described pressure welding case.
Described each branch optical fiber outlet is single setting along the box body Width.
Described each branch optical fiber outlet is provided with at interval.
Adopt said structure, optical cable deconcentrator of the present utility model is by pressure welding case fixedly main cable and each branch optical fiber, connect firm, pressure welding case ends spinning and joins and can guarantee main cable and each branch optical fiber friction phenomenon that in use can not rotate, guarantee the Optical Fiber Transmission stable performance, improve optical fiber serviceable life.
