Description
The utility model is about the combination of a kind of optics, especially passes at light about a kind of device to connect in the module, and in order to receiving or to transmit the optics combination of signal, each parts has good relative positioning after the quick and assembling of the assembling of this optics combination.
In light communication system, place light to pass to connect module and receive or transmit the light signal and realize that the optics combination of photoelectricity signal conversion is very important.Because of this optics combination is to be made of a plurality of parts, and must have accurate relative positioning between each parts, so the assembling of this optics combination is difficult.In view of this, industrial community has the multiple assembling mode of development.
The mode of thermosetting cement assembling optics combination is wherein a kind of.This optics combination comprises a supporting component and a lid, and wherein, this supporting component has one first composition surface, and this lid has one second composition surface.During assembling, earlier lid and supporting component are placed respectively on the upper and lower truing tool of a coupling board, after regulating calibration, first composition surface is contacted with second composition surface, and between this two composition surface, put thermosetting cement, this optical group is share the anchor clamps clamping, to keep the relative positioning of supporting component and lid, then the optics combination is taken off and placed in the temperature control heating furnace from truing tool together with anchor clamps, heat and both are fixed together through certain hour.But, this kind assemble method step is various, and be not suitable for the single-mode fiber transmission system, reason is that the single-mode fiber core diameter only is 6-10 μ m, the relativity shift of assembled components 0.5 μ m can cause very disadvantageous consequence, and take off the back on together with anchor clamps self calibration instrument, transport in the process to it is inserted the temperature control heating furnace in the combination of this optics, easily and other object collision and supporting component and lid position are relatively moved.In addition, exist because of thermograde is arranged in the heating furnace, thermosetting cement occurs when solidifying successively, and causes this calibrated two assembly relative position generation angular deflections.
The existing assembling mode of another kind of optics combination can be consulted United States Patent (USP) the 4th, 969, No. 702 (with reference to Fig. 1), the combination of this optics comprises that laser penetrates diode (LD) 12, supporting component 14, lens (Lens) 16 and lid 18, wherein, this laser diode 12 is to be fixed in the supporting component 14, in order to produce the light wave of certain wavelength, these lens 16 are located on the laser diode 12 and are done suitably location, this lid 18 has a through hole 22, to admit the sleeve 26 of a band optical fiber 24, and this lid 18 is to make optical fiber 24 and laser diode 12 and lens 16 align the back through adjusting to be fixed on the supporting component 14 by ultraviolet freezing plastic (solidifying under the ultraviolet ray irradiation), so that the light that laser diode 12 sends is coupled in the optical fiber 24 and the transmission of realization light signal via lens 16.Yet, after between supporting component 14 and the lid 18 being elder generation's coating one deck ultraviolet ray freezing plastic, placing respectively on the truing tool and through adjusting aligns optical fiber 24 and laser diode 12 and lens 16, fixing by UV-irradiation again to interconnect, in order to make ultraviolet lighting be incident upon ultraviolet freezing plastic, at least one assembly that applies ultraviolet freezing plastic must be transparent, and must consider its profile during the design truing tool, in case block ultraviolet light ultraviolet freezing plastic is solidified, like this, will increase design difficulty and manufacturing cost.
The existing assembling mode of another optics combination can be consulted United States Patent (USP) the 5th, 073, No. 047 (with reference to Fig. 2), this optics combination comprises light source 15, fixed cover 19, housing 17 and socket 1, wherein this light source 15 is to be fixed in the fixed cover 19, the fixed cover 19 of this band light source and housing 17 be by laser dotting in both junctions and form Laser Welding (LBW) contact 16 and be fixed together (being the laser bonding mode), this housing 17 and socket 1 also are in both junctions and form Laser Welding (LBW) contact 18 and be fixed together after regulating calibration by laser dotting.Yet, weld fixing assembly by the laser welding mode and be necessary for metalwork, and must adopt expensive special-purpose laser welding machine to finish.
In order to reduce manufacturing cost, industrial community has the mode that adopts by the combination of Instant cement (InstantGlue) assembling optics in addition, be about to that supporting component and lid place respectively on the truing tool and through regulate calibrate after, at both surface of contact place's point Instant cement rapid solidifications both are connected, and Instant cement is that must to contact the rear with water vapour coagulable, because the water vapor concentration of each point is different and wayward in the three dimensions, therefore Instant cement solidifies has successively, and cause these calibrated two assembly relative positions to be offset, significantly reduce the efficient of light coupled into optical fibres, this kind skew is especially remarkable for the single-mode fiber influence.Still have good relative positioning if make this optical group set up each parts of dress back jointly, this assembly operation must and shake in the certain space that all is subjected to good control in humidity to be finished, and so will improve manufacturing cost.
In view of this, providing a kind of assembles quick and each parts of assembling back to have the optics unitized construction of good relative positioning very necessary.
The purpose of this utility model is to provide a kind of optics combination that each parts of back have good relative positioning of assembling fast and assemble.
Technical characterictic of the present utility model is: it mainly comprises a light source, pedestal and socket.This pedestal is to be formed by plastic material, comprises one first composition surface, the through hole vertical with this first composition surface and the chamber that connects with this through hole, holds a light source in this chamber.One resistance wire roughly is laid near in the pedestal on first composition surface circlewise, and the two ends of this resistance wire are exposed and formed electrical pin, to link to each other with external circuitry and this resistance wire electric energy is provided.This socket can be formed by metal or plastic material, comprises one second composition surface, is to cooperate with first composition surface during assembling, and this socket further comprises a passage vertical with second composition surface.
Compare with existing optics combination, the utlity model has following remarkable advantage: because of being laid with resistance wire near in the pedestal on first composition surface, after the pedestal of optics combination and socket calibration can by electric cocainine evenly heating place between the two thermosetting cement, have pinpoint optics and make up thereby can obtain pedestal and socket rapidly.
