Description

The pressure-cliping novel assembled on site type joints of optical fibre and fiber alignment structure thereof

Technical field

The utility model relates to a kind of coupling arrangement that optical fiber is installed that is used for; The technology that in the middle of handshaking procedure, adopts high precision V-type slotted vane to add side pressure can make optical fiber accurately location and butt joint; The mode that utilization locking upper casing and locking lower casing button bit fasten is covered wire cable fixedly, and suitable working-yard is assembled fast and can be repeated to open and use.

Background technology

At present, the assembled on site type joints of optical fibre device product that is used for repeating opening use mainly adopts dual mode fixed fiber and crust.

Fixing of optical fiber: a kind of through two optic fibre ends realizations of side pressure sheet metal aligning fiber alignment Cheng Duan, another kind is to realize fiber alignment Cheng Duan's through compressing involutory unit of plastic fixed fiber.Wherein in sheet metal or involutory unit of plastic, establish the V-type groove that is used for fiber alignment; Optic fibre end link position at the V-type groove splashes into fluent meterial so that the translucidus of splicing point to be provided; Thereby the action of hold down gag is side pressure sheet metal or involutory unit of plastic reduce V-type line of rabbet joint crack compress aim at optical fiber realize two optical fiber to being connected into end.

Crust fixing: a kind of is that plastics clamp through card optical cable crust utilizes the structure of pawl to realize that a kind of in addition is through threaded tapered sleeve locking cone pawl, and the contraction through the awl pawl is fixing crust directly.

But the shortcoming of prior art is:

Fixing of optical fiber: in the sheet metal secured in alignment mechanism, the coefficient of thermal expansion and contraction of sheet metal and plastics is different, and fibre junction point distance is strengthened, and the performance that continues changes with variation of temperature; Moreover the distortion of burr and metalwork all can appear in any metalwork in the middle of Sheet Metal Forming Technology; Burr can hurt the surface of optical fiber; And the metalwork distortion more can make the interface of two optical fiber produce dislocation; Moreover non-ferrous metal is long-term and air contacting surface chemical reaction can take place and erode metallic surfaces, and this all can directly have influence on the connecting quality of optical fiber.

And the involutory optical-fibre channel of other a kind of unit of plastic is normally closed often, at first need back down briquetting when optical fiber penetrates, but the surface flatness of working of plastics is low; Back down the surface of the central easy damaged V-type groove of process; Produce the plastics chip and pollute splicing point, the logical light of influence causes the decline of connecting quality.And the fluent meterial that improves translucidus is arranged in the middle of the involutory plastics, and its spinoff is that two surfaces are pulled together, the power of backing down when optical fiber penetrates increases greatly, even causes the disconnected fine phenomenon in the process of penetrating.Moreover any working of plastics inevasible problem that drawdown deformation, warpage all can occur in the middle of injection molding process; Badly influence the flatness of fiber alignment passage; Make the interface of two optical fiber produce dislocation, thereby have influence on the quality of final fibre junction.Moreover plastics V groove is because itself hardness is not enough, and through after repeatedly repeating to open, the surface can form irregular depression.Cause the signal stabilization that the decentraction phenomenon of the reduction of optical fiber holding force and butt joint optical fiber is badly influenced optical fiber thus.

Fixing of crust: the plastics denticle in the pawl structure of plastics fixed block; Owing to cannot float; And covered wire cable size on the market has very big difference to cause holding force to have size; Rise easily when the covered wire cable size is big and split the plastic latch locking structure, covered wire cable gets loose easily in the time of little; And other a kind of contraction of boring pawl tapered sleeve of need screwing, the optical cable crust gets loose easily in the middle of the process of screwing, thereby causes splicing point to separate, and influences success ratio.

Ceramic insertion core fixedly be to lean on wringing fit or the sticking mode of glue with working of plastics to realize; Because the instability of plastic material and Shooting Technique; Rise by mating surface easily in the time of tight and split, ceramic insertion core becomes flexible easily or comes off through plugging later on several times in the time of pine, causes signal interruption.

The material of optical fiber is a quartz glass, is metal and at present the V groove passage that docks with it of on the market product is a kind of, and a kind of in addition is plastics.Which kind of V groove to follow optical fiber to match with and all have the inconsistent problem of coefficient of thermal expansion and contraction.Receive temperature variation, material aging easily and influence the quality that continues.
