Description
Technical field
The utility model relates to a kind of photoelectric device, the tail optical fiber contact pin structure of especially using on the photoelectric device.
Background technology
The photoelectric device product of present this area made; realize the laser optical electrical chip in the external fiber transmission or be accomplished to the transmission of detector photoelectric chip from external fiber; need to use optical fiber component, the structure of optical fiber component mainly is made up of ceramic member (ZrO2), metalwork, optical fiber, fiber boot and the joints of optical fibre.Shown in Fig. 1 a, Fig. 1 b, Fig. 2 a and Fig. 2 b, wherein, the hole section 1A diameter 1a that places ceramic member in the metalwork 11 is greater than the diameter 1c that places optical fiber 13 hole section 1C.Ceramic member 11 adopts interference fit method, ceramic member 11 is press-fitted to the bottom of metalwork 12 endoporus, optical fiber 13 adopts the gluing method of viscose glue 14, and metalwork 12 endoporus that will be press-fitted ceramic member 11 earlier inject glue, and then optical fiber 13 are penetrated through ceramic member 11 bottom surfaces of endoporus of metalwork 12.
Because the tight cover material of optical fiber is originally as plastic material, this material itself just has the characteristic that elevated temperature heat is shunk, the optical fiber component that is made thus is under high temperature or high low temperature acting in conjunction, the tight cover material of optical fiber 13 will produce shrinkage phenomenon, because of the bonding strength of optical fiber 13 tight cover materials and viscose glue 14 greater than the bonding strength of viscose glue 14 with metalwork 12 endoporus, when the tight cover material thermal shrinkage force of optical fiber 13 increases to viscous force above viscose glue 14 and metalwork 12 endoporus, the tight cover material of optical fiber 13 will spin off from the endoporus of metalwork 12 with viscose glue 14, causes degumming phenomenon.
The utility model content
In view of this, the technical problems to be solved in the utility model is to provide the structure of the tail optical fiber contact pin on a kind of photoelectric device, when the tight cover material of optical fiber expands with heat and contract with cold, degumming phenomenon can not take place.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of tail optical fiber contact pin structure that is used on the photoelectric device, comprise optical fiber component, the metalwork inside of optical fiber component offers the endoporus of perforation, endoporus is by the ceramic member hole section that cooperates ceramic member and cooperate the optic fibre hole section of optical fiber to form, undertaken bonding by glue between metalwork, ceramic member and the optical fiber, described optic fibre hole section comprises the first optic fibre hole section and the second optic fibre hole section, and the first optic fibre hole section is greater than the second optic fibre hole section diameter.
Described optical fiber is single-mode fiber or multimode optical fiber.
The junction of described ceramic member and optical fiber is provided with the glue section.
Described optical fiber component is fine assembly of direct light or the fine assembly of skew ray.
The technique effect that the utility model reaches is as follows: the bore design of the metalwork in the utility model optical fiber component is the different multi-section type cylindrical structural of diameter.When connect between ceramic member, metalwork and the optical fiber the space through injection the form of viscose glue, solidify connect after, viscose glue forms the thickness different step shape similar with the aperture, promptly thick earlier after thin form.Even the tight cover material of optical fiber under high temperature or high cold service thermal shrinkage takes place, but because viscose glue has formed the thin step shape in thick earlier back, had the location barriers function, optical fiber can't enter thin end from butt end, prevents degumming phenomenon effectively.In addition, optical fiber component is in manufacturing process, and ceramic member is connected an end and reserves the glue section with optical fiber, increased the area and the glue consumption of viscose glue, has increased the intensity of optical fiber and ceramic member junction viscose glue, has further played the effect that prevents that optical fiber from coming unstuck.

Embodiment
As Fig. 3 a, Fig. 3 b, Fig. 4 a and Fig. 4 b, for the utility model is used for tail optical fiber contact pin structure on the photoelectric device, a kind of tail optical fiber contact pin structure that is used on the photoelectric device, comprise optical fiber component, optical fiber 23 can be single-mode fiber or multimode optical fiber, optical fiber component of the present utility model can be the fine assembly (referring to Fig. 3 a and Fig. 3 b) of direct light, also be applicable to the fine assembly (referring to Fig. 4 a and Fig. 4 b) of skew ray, when the difference of fine assembly of direct light and the fine assembly of skew ray only is that metalwork 22 is offered endoporus, the slightly inclination of certain angle of endoporus of the fine assembly of skew ray, concrete difference sees also Fig. 3 a and Fig. 4 a.The inside of the metalwork 22 of optical fiber component offers the endoporus of perforation, and this endoporus is by the ceramic member hole section 2A that cooperates ceramic member and cooperate the optic fibre hole section of optical fiber to form, and this optic fibre hole section comprises the first optic fibre hole section 2B and the second optic fibre hole section 2C again.The first optic fibre hole section 2B diameter 2b is again greater than the second optic fibre hole section 2C diameter 2c.Metalwork 22 is provided with viscose glue 24 with the junction of optical fiber 23, is undertaken bonding by injecting viscose glue 24 between metalwork 22, ceramic member 21 and the optical fiber 23.
