Description
Technical field
The present invention relates to a kind of method for making of the molten end type skin cable joints of optical fibre, belong to technical field of optical fiber communication.
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, in use, there is following problem in field assembled fiber active linker high volume applications: 1, direct-pass type optical fiber connector fiber cut end face is not measured, and causing insertion loss to exceed standard cannot open.2, the pollution of pre-buried optical fiber flexible jumper matching fluid and matching fluid run off and cause continuing unsuccessfully.3, hot melten type operation easier is large, causes packaging qualification rate low.4, cut to cut quality in work progress cannot ensure, cutting end face is bad, can not meet assembling requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method for making of the molten end type skin cable joints of optical fibre, these molten end type skin cable joints of optical fibre solve connector matching fluid and to pollute and matching fluid loss causes continuing that failure and fiber cut quality cannot ensure, to cut end face bad, ensure that tensile strength, continued stable performance, improves serviceable life.
In order to solve the problems of the technologies described above, the method for making of a kind of molten end type skin cable joints of optical fibre of the present invention, the method comprises the following steps:
Step one, at lock pin afterbody point glue, by the lock pin alignment box shell after a glue, is inserted in case shell;
Step 2, is placed on vacuum formed box by the case shell inserting lock pin, covers cover plate, put into baking box and toast;
Step 3, take out case shell and leave standstill, load onto case lid after leaving standstill on case shell, after case shell is connected with case lid, a side end forms notch;
Step 4, puts into frock lower bottom base draw-in groove by the case shell that case lid is housed, and folder spring is put into frock cover plate folder spring groove, then makes folder spring be stuck on case lid and case shell by conjunction auxiliary mould;
Step 5, at case shell afterbody pocketed springs;
Step 6, had by cover the case shell of spring to be provided with in the housing of hole by pressing machine press-in surface, housing afterbody is provided with device for fastening;
Step 7, the pertusate shell of surface band on outside cover, the hole on notch and housing, shell is on the same line;
Step 8, prepares key, by key inserting slot mouth.
In described step one, lock pin is punctuated at afterbody 1-2mm place one glue.
The case shell inserting lock pin in described step 2 is 60 DEG C in the temperature of oven cooking cycle.
The case shell inserting lock pin in described step 2 is 120 minutes at the baking time of oven cooking cycle.
Described step 3 raising middle flask shell time of repose is 12 hours.
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, 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; 3, adopt the design of non-fiber matching fluid, produce and pollute in use procedure, after molten end, fiber end face is directly worn fine to lock pin surface by interiors of products, controls optical fiber bulge quantity by optical fiber height positioning device; 4, adopt the direct Cheng Duan of site operation, after at the construction field (site) fiber end face being processed, be made into end, be applied directly to FTTH terminal, replace plant ground technology, belong to new technique field; The fiber end inspection probe that 5, can be carried by optical fiber welding terminal, is observed the fiber end face after molten end, judges to continue effect, belong to visualized operation, more secure power.
