Background technology
Optical cable manufactures in order to the performance specification meeting optics, machinery or environment, and it utilizes one or more optical fiber being placed in coated sheath as transmission medium and the communications cable assembly that can use separately or in groups.Optical cable is mainly made up of the light transmitting fiber glass fiber of hair (thin as) and plastic protective sleeve pipe and plastic peel, does not have the metal such as gold, silver, copper aluminium, generally without recovery value in optical cable.Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, the also coated outer jacket had, in order to realize a kind of communication line of optical signal transmission.That is: the cable formed through certain technique by optical fiber (optical transmission carrier).The basic structure of optical cable is generally made up of a few parts such as cable core, reinforcement steel wire, filling material and sheaths, also has the components such as water barrier, cushion, insulated metal wire as required in addition.
Optical cable is total reflection principle in a kind of fiber utilizing light to make at glass or plastics and the light reached passes to instrument, have a wide range of applications in the communications field, need to remove overlayer, to carry out ensuing treatment process in the process of optical cable processing.
Usual optical fiber and optical cable two nouns can be confused.Most optical fiber before use must be coated by which floor operator guards, and namely the cable after coated is called as optical cable.The protective seam of fiber outer layer and insulation course can prevent surrounding environment to the injury of optical fiber, Ru Shui, fire, electric shock etc.Optical cable is divided into: cable skin, aramid fiber yarn, cushion and optical fiber.Optical fiber is similar with concentric cable, does not just have mesh shields layer.Center is the glass core that light is propagated.
In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.
Along with Fibre Optical Communication Technology development, supporting site of deployment connector presents variation, and the field assembled flexible jumper that existing market uses is divided three classes: through type field assembled fiber active linker, built-in type field assembled fiber active linker, hot melten type field assembled fiber active linker.These three kinds of connectors all have requirement to on-site cutting fiber end face, existing market factory cutter quality is uneven, blind area is there is in workmen to optical fiber cutter serviceable life and cutter maintenance, cause field optical fibers cut quality cannot meet connector redirect request, finally cause optical property to exceed standard, continue unsuccessfully.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of molten end type skin cable joints of optical fibre, these molten end type skin cable joints of optical fibre carry out three places to optical fiber, optical fiber coating and covered wire cable and tighten up, ensure that tensile strength, continued stable performance, improves serviceable life.
In order to solve the problems of the technologies described above, the molten end type skin cable joints of optical fibre of the present invention comprise ferrule assembly, spring, housing, shell, key, the tail shell of the equal opening in two ends, covered wire cable, described ferrule assembly comprises lock pin, case shell, case lid, folder spring, lock pin is arranged in case shell front end, case shell side coupling connects case lid, after case shell is connected with case lid, a side end forms notch, folder spring is stuck on case lid and case shell, spring housing is on the cylinder of case shell afterbody, the cylinder tip of case shell afterbody is provided with ring-shaped step, contact pin component penetrates from housing forward end, described housing mid-section position is provided with step, housing tail end is provided with fastener, contact pin component is fastened on the step of housing by ring-shaped step, described housing, shell is equipped with hole, on housing, cover has shell, notch and housing, hole on shell on the same line, key is inserted in notch, key and notch removably connect, described tail shell and housing tail end removably connect.
Described folder spring is U-shaped folder spring.
Described folder spring is made up of metal material.
Described key and notch snapping.
Described tail shell is threaded with housing.
Adopt this molten end type skin cable joints of optical fibre, have the following advantages:
1, this structure can carry out cutting end face processing at the scene to optical fiber, ensure that the quality of fiber end face, and this structure can be assembled at the scene; 2, this structure makes the splicing point of optical fiber be arranged on lock pin outer face, adopts the inner design without matching fluid, avoids in use procedure to produce and pollutes; 3, because folder spring is stuck on case lid and case shell, housing tail end is provided with fastener, namely carries out three places to optical fiber, optical fiber coating and covered wire cable and tightens up, ensure that tensile strength, and continued stable performance, improves serviceable life.
