Abstract
The utility model provides a plastic-packaging coaxial optical assembly. The assembly comprises a TO-CAN pipe core, a metal tube core seat, a metal adjustment ring and a plastic adapter casing pipe. The metal tube core seat and the metal adjustment ring are fixed through laser welding. The plastic adapter casing pipe is externally connected with the metal adjustment ring and is fixed through a glue. A center of the plastic adapter casing pipe is provided with a light through hole and an adapter insertion hole. The TO-CAN pipe core is a laser diode core which emits a 1310nm or 1550nm wavelength light signal. The TO-CAN pipe core is a photoelectric diode core which receives the 1310nm or 1550nm wavelength light signal. The optical assembly of the structure has less structural components whose number is four. The plastic adapter casing pipe is used and the light through hole and the adapter insertion hole are arranged in the casing pipe. A ceramic sleeve and an optical fiber ceramic insertion core with high prices are not needed. Cost of the whole assembly is greatly reduced so that a requirement of low cost of optical network equipment in a security and protection system is satisfied.
Description
Technical field
The utility model relates to a kind of optical assembly, relates in particular to a kind of coaxial optical of plastic package.
Background technology
Coaxial optical comprises coaxial transmitting optical assembly and coaxial receiver optical assembly, and coaxial optical is widely used in optical network system.Coaxial optical primary element comprises TO-CAN tube core and fiber adapter.The light output end of fiber adapter and external fiber connector fibre core end face need accurately be coupled and aligned just can reach effective luminous power input, output, and the repeated multiple times plug of joints of optical fibre energy, therefore higher for the fiber adapter structural requirement of coaxial optical.At present, the coaxial optical extensively adopting as shown in Figure 1, comprise: a TO-CAN tube core 10, a metal regulating ring 20 and an adapter 30, this adapter 30 comprises: a metal sleeve 31, ceramic sleeve 32 1 optical fiber ceramic lock pins 33, first optical fiber ceramic lock pin 33 utilizes glue to be fixed in ceramic sleeve 32, this ceramic sleeve is fixed in metal sleeve 31 again, after the light end face of optical fiber ceramic lock pin 33 and the chip of TO-CAN tube core 10 carry out optically-coupled and regulate and aims at, metal sleeve 31 is fixed by Laser Welding (LBW) and metal regulating ring 20.This structure coaxial optical, its components and parts are more, complex structure, in security light network system, when the practical application of a large amount of low rate coaxial opticals that adopt, it is too high that cost seems.
Utility model content
For overcoming above shortcoming, it is a kind of simple in structure that the utility model provides, the coaxial optical of the plastic package that cost is low.
For realizing above goal of the invention, the utility model provides a kind of coaxial optical of plastic package, comprise: TO-CAN tube core, a metal die paddle, a metal regulating ring and a plastic adapter sleeve pipe, described metal die paddle and metal regulating ring are fixed by Laser Welding (LBW); The external metal regulating ring of plastic adapter sleeve pipe is fixed by glue, and its center of plastic adapter sleeve pipe is provided with light hole and adapter patchhole.
Described TO-CAN tube core is laser diode core.
Described TO-CAN tube core is photodiode core.
The coaxial optical of the plastic package of said structure, because structural member is less, only four, and adopt plastic adapter sleeve pipe, in this sleeve pipe, be provided with light hole and adapter patchhole, do not need ceramic sleeve and optical fiber ceramic lock pin that price is higher, the cost of whole assembly significantly reduces, external fiber connector plugging is also very convenient, is applicable in safety-protection system the requirement of optical network device low cost very much.
Accompanying drawing explanation
Fig. 1 represents the coaxial optical structural representation of prior art;
Fig. 2 represents the coaxial optical structural representation of the utility model plastic package.
Embodiment
The coaxial optical of plastic package as shown in Figure 2, comprising: TO-CAN tube core 1, a metal die paddle 2, a metal regulating ring 3 and a plastic adapter sleeve pipe 4, and metal die paddle 2 and metal regulating ring 3 are fixed by Laser Welding (LBW); The external metal regulating ring 3 of plastic adapter sleeve pipe 4 is fixed by glue, and plastic adapter cover tube hub is provided with light hole 41 and adapter patchhole 42.The pipe cap of TO-CAN tube core 1 is provided with lens, and in the time that TO-CAN tube core 1 is laser diode core, transmitting 1310nm or 1550nm wavelength light signal, converge to light hole 41 by pipe cap lens, exported by the external fiber connector of adapter patchhole 42 interior insertions.In the time that TO-CAN tube core 1 is photodiode core, by external fiber connector input 1310nm or 1550nm wavelength light signal in adapter patchhole 42, enter rear light signal by light hole 41 and converge to photodiode core 1 by pipe cap lens and receive, realize opto-electronic conversion.
