Description
Technical field
The utility model relates to a kind of optical communication device in the optical communication industry, the particularly fiber adapter of the integrated module of optical transceiver.
Background technology
In the miniaturization integrated module of optical transceiver, generally all comprise a miniaturization light receiving element 5(ROSA), common modular structure is seen Fig. 1, comprises in the integrated module of optical transceiver that the supporting metalwork of metal module loam cake 1, lower cover 2 and some 3, driving circuit 4, a miniaturization optical transmitting set TOSA(are not shown) and a ROSA form.Light signal is given ROSA by Optical Fiber Transmission, and changes into electric signal by ROSA, thereby realizes the signal transmission.
Fig. 2 is common miniaturization light receiving element structure, it mainly is made up of 4 parts: fiber adapter 6(as shown in Figure 3, housing adopts the integral type metal shell), light emitting diode 7(TO-Can is a kind of photodiode of transistor encapsulation, major function is that light signal is changed into electric signal), Z jacket 8 and metallic sheath 9.Their sheathing material all is a metal basically, and the characteristic of signal shielding is arranged.
In some high-speed applications, for being reduced, disturbs receiver-transmitter integrated module, improve performance, the signal ground and the earthing of casing must be isolated mutually.So-called signal ground refers to the partial earth that all link to each other with the conducting of TO-CAN shell; The so-called earthing of casing refers to all partial earths that link to each other with the conducting of receiver-transmitter integrated module shell.But because fiber adapter all is the entity contact when being fixed on the metal shell, and material all is metallic object, will encounter difficulties so the electricity between the signal ground and the earthing of casing is isolated.
Present a solution is to use some epoxide-resin glues (insulator) that TO-CAN and metal shell and fiber adapter are sticked together and makes the miniaturization light receiving element.Though this scheme also can realize the effect that electricity is isolated, in fact, this scheme with respect to using laser bonding, has following three deficiencies with the epoxy resin stickup in the low speed optical communication applications:
1) carries out in the assembling process, might influence light transmission being glued to the surface of optical element.
2) in the adhesive curing process, good product produces micro-displacement can to make coupling.In some low-speed communications, because the chip photosensitive area is big, may not can influence performance, but in high speed device, because chip area is little, micro-displacement just causes the bad of product most probably, influences yield.
3) from the reliability aspect, reliability is not as laser welding process.
In sum, want promptly to accomplish that electricity is isolated wants that again making the miniaturization light receiving element with laser welding process is a difficult problem.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of fiber adapter of charged isolation, and is simple and reasonable, and the problem that effective address signal ground connection and earthing of casing electricity are isolated adopts laser welding process to make simultaneously, and isolation effect is good.
To achieve these goals, the utility model has adopted following technical scheme: the fiber adapter of charged isolation, the fiber adapter housing is split type, between afterbody metal shell and the assembling end metal shell insulating sleeve is housed, the insulation contact pin is housed in the insulating sleeve, connects afterbody metal shell and assembling end metal shell by insulation contact pin riveting.
Described insulating sleeve adopts ceramic sleeve.
Described insulation contact pin adopts ceramic contact pin.
The utility model is simple and reasonable, by with fiber adapter housing splitization, realize the automatic charged isolation of two housing sections, it is more attractive in appearance again to have increased intensity simultaneously, when adopting the utility model fiber adapter to make miniaturization light receiving element (ROSA), the signal ground of metal shell and light emitting diode TO-can can connect together by laser bonding, the assembling end metal shell laser bonding of TO-can and fiber adapter connects together, assembling this moment end metal shell is a signal ground, the afterbody metal shell of fiber adapter and signal ground are realized the electricity isolation by insulating sleeve and built-in electrical insulation contact pin, therefore, after being installed in the module, also realized ROSA the isolation of the signal ground and earthing of casing electricity.
Fiber adapter of the present utility model is applicable to the fiber adapter of different shape and structure, does not change act.std, has from charged isolation performance, characteristics such as that employed electric isolated material has is high temperature resistant, high temperature, good reliability.
