Description
Technical field
The utility model relates to the optically-coupled field, particularly a kind of optical connector.
Background technology
In general, the coupling fiber of spatial light is mainly by solid state laser, the laser beam that semiconductor laser etc. send focuses on or is imaged onto on the fiber core end face after by beam shaping, the light guide of optical fiber is comprised of fibre core and covering, the refractive index of fibre core can be slightly larger than the refractive index of covering, like this, when the light angle of divergence that incides the fiber core end face is less than the numerical aperture NA of optical fiber, after entering fibre core will total reflection occur in the interface of fibre core and covering, and the light angle of divergence that incides the fiber core end face is while being greater than Optical Fiber Numerical Aperture NA, even enter fibre core can total reflection not occur in the interface of fibre core and covering yet, therefore can reflect optical fiber very soon and can not transmit at fibre core.In general, the coupling fiber of spatial light always has certain coupling efficiency, is difficult to reach 100%, that is to say that some light of total existence finally can't transmit along fiber core.
The schematic diagram that Fig. 1 is the spatial beam coupling fiber, single cladded-fiber light guide comprises fibre core 61 and covering 62, spatial beam 64 is when coupling fiber, can be along fibre core transmission except entering fibre core 61 and meeting the light 65 of total reflection condition, other light is all the light be not coupled into, can be divided into three parts: at the end face reflection light 68 of end face 63 reflection of optical fiber, at the cladding light 66 of covering 62 transmission, and parasitic light 67.Cladding light 66 and parasitic light 67 finally all can be transformed into heat.
Existing optical connector be all generally by cantilever beam structure by being protected by air gap near optical fiber head, then carry out in the back pattern and peel off, prevent that cladding light is transferred to rear end damage optical fiber coating and sheath.This structure is applicable to for doing docking of optical fiber and optical fiber, but during for the coupling of the spatial light of laser instrument, the light beam of coupling is that the laser beam of sending from laser cavity surface obtains after a series of optical element carries out beam shaping, cause aberration owing to remaining diffraction and optical element, so being coupled to the laser beam of fiber end face is not probably desirable Gaussian beam, even the mode that optical fiber direct is right, also be difficult to accomplish that optical fiber parameter and laser instrument mate fully, therefore in the luminous power of loss, near parasitic light end face can account for very large proportion, and in fact the light of coupled into optical fibres can all do not beaten be transformed into heat on optical connector, easily cause the optical connector excess Temperature and damage.It is the Chinese utility model patent of CN201408271Y that Granted publication number is separately arranged, and has introduced a kind of high concentricity metalized optical fiber wire jumper connector.This scheme is welded with golden tin solder by metallized optical fibre and connector, has avoided near fiber end face using glue, thereby can be not former thereby cause that connector lost efficacy because of be heated burning etc. of glue.Simultaneously optical fiber head adopts common cantilever beam structure on market, can avoid fiber end face to be subject to thermal failure, but this scheme can only strengthen the fire damage threshold value of optical connector, can not reduce the heat that optical patchcord produces on connector in use.The schematic diagram of the optical fiber jumper terminal of the Chinese utility model patent that Fig. 2 is Granted publication CN201408271Y, lock pin 71 front ends of cantilever beam structure have a groove 72, and optical fiber 73 is fixed on lock pin 71 center, and forms cantilever beam structure by groove 72.When spatial beam 74 incides fiber end face, the parasitic light 75 of coupled into optical fibres, not away from lock pin 71, does not change into heat but shine directly on lock pin 71.Therefore simultaneously, because the size of lock pin 71 is generally smaller, radiator structure is also poor, is easy to elevate the temperature and damages lock pin 71.
