The utility model relates to a rationally, the matching degree is good, improves optical fiber jumper wire's bulk strength, when guaranteeing small -size, has improved LC type optical fiber jumper wire's whole tensile strength, simultaneously, the utility model discloses increase the tail sheath at back casing afterbody, the thin footpath optical cable of protection can not be impaired under bending for a short time.
Description
Technical field
The utility model belongs to a kind of novel LC type thin footpath optical patchcord.
Background technology
Current communication facilities, optoelectronic device, electronic equipment integration degree are more and more higher, device interior module gets more and more, communication linkage between module is more complicated, also more and more higher to the requirement of connecting line, should have certain installation strength, take up room the smaller the better (namely cable requires thinner).For integrated optical communication equipment, by space constraint, its optical cable wire diameter of optical patchcord as light-path carrier wants thin, the joints of optical fibre are little, and owing to being subject to himself Action of Gravity Field in optical patchcord installation process, equipment is installed, also can there is certain installing force when smoothing out with the fingers line, and can there is the External Force Actings such as vibration, impact during equipment conveying, therefore has certain strength of joint requirement to optical patchcord.
But current wire jumper also exists defect, one is that strength of joint is low, generally only has a few Newton force, only can be used for the simple connection of light path and connection procedure should not be subject to larger external force, cannot meet the request for utilization of integrated equipment.Two is that wire jumper size is comparatively large, adopts this optical patchcord by installing space larger for the equipment that takies, affects the integration degree of equipment.
Summary of the invention
In order to overcome the deficiencies in the prior art; the utility model provides a kind of high-precision optical fiber attenuator; reasonable in design; matching degree is good, improves the bulk strength of optical patchcord, ensureing undersized while; improve the overall tensile strength of LC type optical patchcord; meanwhile, the utility model increases tail sheath at back casing afterbody, protects thin footpath optical cable can not be impaired under little bending.
The utility model solves the technical scheme that its technical matters adopts:
A kind of novel LC type thin footpath optical patchcord, comprise optical cable and be arranged on the LC type joints of optical fibre at optical cable two, it is characterized in that: described optical cable comprises the optical fiber in centre position, the lateral surface of optical fiber is enclosed with enhancement Layer, flame-retardant layer, puncture-resistant layer, outer jacket from inside to outside successively; Described enhancement Layer is made up of at outer fiber polymer liquid crystal resin extrusion molding; Described outer jacket is made up of PVC plastic; Described flame-retardant layer is made up of fire-retardant fireproof cloth; Described puncture-resistant layer is made up of aluminum foil material.
As a kind of technical scheme of optimization, the described LC type joints of optical fibre comprise polygon shell, the optical cable be arranged in polygon shell; Described optical cable is fixed in polygon shell by ring flange, current limiting tube and the spring be arranged between current limiting tube and polygon shell.
As a kind of technical scheme of optimization, described LC type thin footpath optical patchcord also comprises the tail sheath being sleeved on polygon shell and optical cable contact site.
As a kind of technical scheme of optimization, the diameter of described optical cable is 0.7-0.9mm.
Owing to have employed technique scheme; compared with prior art; the utility model is reasonable in design; matching degree is good, improves the bulk strength of optical patchcord, ensureing undersized while; improve the overall tensile strength of LC type optical patchcord; meanwhile, the utility model increases tail sheath at back casing afterbody, protects thin footpath optical cable can not be impaired under little bending.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
