Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment;
Fig. 2 is the schematic diagram of the glass capillary of the utility model preferred embodiment.
Embodiment
Below in conjunction with embodiment, the utility model will be further described.
As shown in Figure 1 and Figure 2, a kind of integrated optical-electric module for photoelectric conversion part, comprise photoelectric conversion chip 1, import optical fiber 2, photoelectric conversion chip 1 is fixed on substrate, one glass capillary 3 is set, glass capillary arranges a through hole 31, through hole 31 runs through front end and the end of glass capillary, the end of glass capillary arranges the breach 33 that can place photoelectric conversion chip, through hole 31 is above breach 33, import optical fiber insertion through hole extend glass capillary end termination and fix, glass capillary end termination arranges an inclined-plane 35, importing the termination of optical fiber in glass capillary end end arranges a termination inclined-plane identical with glass capillary end termination bevel angle, glass capillary end termination is placed on the light sensation mouth of photoelectric conversion chip 1.
Breach 33 is at least switched to through hole 31, and the termination importing optical fiber is placed on the light sensation mouth of photoelectric conversion chip 1.Breach 33 is switched to through hole 31, and the side importing optical fiber 2 termination is exposed, and allows the termination importing optical fiber 2 press close to the photosensitive area of photoelectric conversion chip 1, more reduces the loss of light signal.
Through hole 31 arranges insertion in insertion end and leads mouth 37, and insert the bore of leading mouth 37 and be greater than the bore importing optical fiber 2, insertion is led mouth 37 and is provided with transition chamfering with through hole 31 junction; Insertion is led arranging of mouth 37 and is facilitated lead-in light fibre 2 to be inserted in through hole 31.
Through hole 31 is arranged along glass capillary length direction.Preferably, through hole 31 is arranged on the axle center district of glass capillary 3, is convenient to drilling of through hole 31, also facilitates glass capillary 3 to adjust with coordinating of miscellaneous part simultaneously.
The angle a on described inclined-plane is 15 ° ~ 50 °; Preferably, the angle a on inclined-plane is 25 ° ~ 40 °.Effective inclined-plane forms minute surface, reduces the loss of light reflection while can effectively increasing fiber reflection area.
Arranging UV glue point of fixity 6, UV glue 6 between glass capillary 3 and substrate can be fixed on substrate by glass capillary 3 fast, and several seconds set time of UV rubber ultraviolet light line was by tens seconds.UV glue is a kind of ultraviolet fast curing adhesive, has epoxy and non-epoxy.
Importing optical fiber 2 termination being in glass capillary end termination is pasted onto on the light sensation mouth of photoelectric conversion chip 1 by bonding agent 7.Cementing agent 7 adopts the binding material that shrinkage factor is little, high temperature resistant, light transmission is good, the materials such as such as heat-curable epoxy resin, 200 DEG C of continuous workings, also can bear the high temperature of a few hours 300-400 DEG C and performance is constant, transmittance is good, the dissolving of the anti-multi-solvents of energy and chemicals and etch.
Be provided with encapsulating glue-line 5, glass capillary end and photoelectric conversion chip be locked in and encapsulate in glue-line 5.Encapsulating glue-line 5 adopts that shrinkage factor is little, hardness is high, bonding strength is high, the epoxide resin material of high-temp resisting high-humidity resisting.Except epoxy resin, as long as parameter meets, shrinkage factor is little, hardness is high, bonding strength is high, the glue of high-temp resisting high-humidity resisting requirement can use.
Meet the bonding agent of parameter request, UV glue, encapsulating compound all have commercially available.
The effect of glass capillary 3 has 2 points: 1, solve a grinding difficult problem, because optical fiber is very soft, the fibre core peelling off protective seam is glass material, very crisp, and diameter only has 125 microns, easily broken.Bare fibre technique will solve the clamping problem of soft and crisp optical fiber, and cost intensive and consumptive material are not environmentally.Adopting after kapillary can clamping ends, and solve the problem that optical fiber is soft and crisp, customization grinding clamp can be produced in batches.2, a coupling table clamping difficult problem is solved, bare fibre be coupled time because of optical fiber from circuit board very close to, cannot clamping ends position, circuit board outer position can only be clamped in, but now optical fiber is extended with 3 ~ 4 centimetres, the optical fiber being in free state can be arbitrary shape, need sextuple above coupling table just can complete coupling, but efficiency is extremely low.Optical fiber can be shifted because of the surface tension of glue again when rear glue is fixed even if be coupled.Adopting after kapillary can clamping ends, only needs the three-dimensional platform of X, Y, Z just can complete coupling, substantially increases efficiency, and can not be shifted when putting glue.
The utility model by direct for photoelectric conversion chip plane attachment on circuit boards, eliminates TO base, pipe cap; The glass capillary of custom-designed grinding angle is fixed on circuit boards after coupling completes, and adopts UV glue to be filled between kapillary and chip, eliminates metalwork, ceramic insertion core and laser spot welder.The utility model reduces production cost, is applicable to batch production.
