Background technology
The single fiber bi-directional transceiver is that the collection sending and receiving are the electrooptical device of one, adopt the recovery technology, in same optical fiber, finish transmitting and receiving of light, use an optical fiber just can realize the data double-way transmission, has identical function with two fibres, the transmission longest distance is 120 kilometers, saves optical fiber, reduces cost.The single fiber fiber optical transceiver must use in pairs, i.e. 1310nm emission, 1550nm reception receive with 1550nm emission, 1310nm or other two kinds of wavelength pairing uses, are the main devices in the optical communication system at present.Fig. 1 has reflected single fiber bi-directional transceiver operation principle, the light that laser is launched a kind of wavelength X 1 (as λ 1=1310nm) passes 45 ° of filter plates 41, go out by Optical Fiber Transmission then, the light of another kind of λ 2 (as λ 2=1550nm) wavelength is come in by Optical Fiber Transmission, be received device 1 by 0 ° of filter plate 11 again by 41 reflections of 45 ° of filter plates and receive, realized the data double-way transmission on an optical fiber.Fig. 2 has reflected the mounting structure of optical fiber in the prior art, receiver 1 is connected with housing 2, according to designing requirement, housing 2 is a metallic object, receiver 1 need keep insulation with housing 2, and receiver 1 is the function that has realized fixing and insulation by the mode that directly is coated with insulation adhesive-layer 6 on the joint gap of receiver 1 and housing 2 with being connected of housing 2 in the prior art.The shortcoming of this package assembly is, because the coated weight of viscose glue is bigger, is difficult to be undertaken by the mechanical mode automation, thereby need the more manpower of input to install, inefficiency, and, reduced reliability of products because the viscose glue resistance to elevated temperatures of junction is poor.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, improves the assembly working efficient of assembly, and improves the resistance to elevated temperatures and the unfailing performance of product, and a kind of package assembly of single fiber bi-directional transmitting-receiving subassembly is provided.
The technical solution adopted in the utility model is: receiver (1), housing (2), described receiver (1) link together by the interface holes (21) on the housing (2) with housing (2), it is characterized in that, the insulation base (3) that hollow is arranged between described receiver (1) and the housing (2), the interior hole shape of insulation base (3) and the external diameter shape of receiver are complementary, receiver (1) is fixed together by adhesion process with insulation base (3), and insulation base (3) is fixed on the housing (2) by the mode of welding.
Adopt the package assembly of such scheme, the external diameter shape of insulation base endoporus shape and receiver is complementary, thereby the coupling of the receiver of being more convenient for is regulated, improved packaging efficiency, insulation base injection molding way processes, be applicable to large-scale production, improved operating efficiency, reduced product cost.
