Embodiment
Optical fiber coupled connector that the present technique scheme is provided below in conjunction with accompanying drawing and embodiment and preparation method thereof is elaborated.
See also Fig. 1 and shown in Figure 2, the optical fiber coupled connector 10 that an embodiment of the present invention provides comprises plug end 20 and socket end 30.Socket end 30 can be located at equipment such as main frame, printer, camera, and plug end 20 is Portable, is used for cooperating with socket end 30, and data are inputed or outputed to aforementioned device.
The end that header body 11 has first lens 13 is provided with two reference columns 110.This two reference column 110 is located at the both sides of these 4 first lens 13 respectively.Every reference column 110 is conical, and its diameter reduces to the direction away from header body 11 gradually.
Please consult Fig. 2 and Fig. 4 in the lump, socket end 30 comprises jack body 12, four second optical fiber 121 and four second lens 14.These four second optical fiber 121 are located in the blind hole (figure does not show) of this jack body 12.These four second lens 14 are embedded at an end of this jack body 12.Each second lens 14 is corresponding with one first lens 13, and comprise second optical surface 141 and with the second opposing coupling surface 142 of this second optical surface 141.Second lens 14 and jack body 12 are also low and the mobile transparent plastic better than polyetherimide is one-body molded through jetting formation process than polyetherimide by fusing point.As for the material of this transparent plastic, those of ordinary skills can according to actual needs and combine self knowledge and experience selected voluntarily.The material of second lens 14 and jack body 12 is same as first lens 13 and header body 11.Second optical surface 141 that is same as first lens, 13, the second lens 14 also is formed with hyaline membrane 40.
The reference column 110 of corresponding plug body 11, an end that is positioned at second lens 14 of jack body 12 is provided with pilot hole 120.The diameter of pilot hole 120 increases to the direction away from jack body 12 gradually, thereby makes an end aligned hole 120 that reference column 110 diameters are less and the diameter larger part inserts pilot hole 120.When reference column 110 inserts the optical axis coincidence of pilot hole 120, the first lens 13 and second lens 14, and has certain distance between first lens 13 and second lens 14 with coupling optical signal preferably.Reference column 110 can be other shape, and as cylindrical, the shape of pilot hole 120 needs corresponding change.
In addition, the hole wall of these reference column 110 surfaces and this pilot hole 120 also can be coated with wear-resisting rete, improves reference column 110 and the surface abrasion resistance property of jack body 12 in pilot hole 120.
This optical fiber coupled connector 10 can be processed by following method.
At first; Low and mobile transparent plastic particle or the powder better than polyetherimide are raw material than polyetherimide with fusing point; Like polymethylmethacrylate; Through this area common ejection formation board and the interfacing equipment one-body molded making header body 11 of difference and first lens 13, and the jack body 12 and second lens 14.Be appreciated that because this raw material fusing point is low ejection formation board temperature is controlled to the fusing point of this raw material, and raw material will be melt into heat and melt body, the die cavity of full mould has preferable molding effect.
Secondly, form hyaline membrane 40 respectively at first optical surface 131 of first lens 13 and second optical surface 141 of second lens 14.This hyaline membrane 40 can be processed through the common coating process in this area such as reaction equation sputter, chemogenic deposit.The material of this hyaline membrane 40 can be decided according to actual needs, for example, can plate silicon dioxide layer, five oxidations, three titanium layers, five oxidations, two thallium layers in this first optical surface 131 and second optical surface 141 successively respectively, and the gross thickness of above-mentioned each coating is between 1 to 3 micron.
For improving reference column 110 and the surface abrasion resistance property of jack body 12 in pilot hole 120, can be coated with the common wear-resisting rete in this area in the hole wall of these reference column 110 surfaces and this pilot hole 120.
At last, 111 groups of first optical fiber are gone in this header body 11, and make this first optical fiber 111 relative with this first coupling surface 132; 121 groups of second optical fiber are gone in this jack body 12, and make this second optical fiber 121 relative with this second coupling surface 142.This first optical fiber 111 and second optical fiber 121 can be fixed in predetermined blind hole through dotting glue method.
The method for making of this optical fiber coupled connector adopt cheap and fusing point than polyetherimide the low and mobile transparent plastic better than polyetherimide; Ejection formation board and the interfacing equipment common through this area promptly can be made into required optical fiber coupled connector, can reduce raw materials cost and equipment cost greatly thus.In addition, compared to polyetherimide, the plastics of this method for making uses have than low melting glass, so several of this ejection formations just can be with this plastics fusion in lower temperature, thereby the saving heating energy source further reduces production costs.And,, can keep the optical characteristics of this optical fiber coupled connector in conjunction with coating process.
It is understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.These all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
