Abstract
The utility model relates to a metal dust cap used in an optical fiber transceiver. The utility model adopts the following technical proposal that: the metal dust cap used in an optical fiber transceiver comprises a cap body, wherein a dust cap core insert is inserted into the inside diameter of the cap body; the outside diameter of the dust cap core insert is matched with and in close fit with the inside diameter of the ceramic ring of an optical fiber transceiver. An optical fiber laser adopting the technical proposal is not easy to adsorb dust and is convenient for cleaning because the cap body is made of stainless steel and the dust cap core insert is made of ceramics; moreover, because the dust cap core insert is in close fit and firm connection with the ceramic ring, the metal dust cap is not easy to break off from the transceiver during heat treatment, thereby improving the protection of the end face of a ceramic core insert during high and low temperature cycle processing.
Description
Technical field
The utility model relates to the processing technique field of the fiber optical transceiver parts in the optical communication technique, relates in particular to a kind of metal dust cap that is used for fiber optical transceiver.
Background technology
The plug-in fiber optical transceiver must carry out high low temperature and circulate and eliminate the stress of laser bonding after laser bonding in high low temperature circulating box, make properties of product stable.The optical fiber ceramic insertion core end face is the minute surface of polishing, very easily pollutes, and in cycle period, not contaminated in the protection device uses the rubber dust cap to be enclosed within on the cylindrical of socket usually, makes that jack is inner isolates with extraneous air.The user mode figure of the rubber dust cap of prior art as shown in Figure 1, optical fiber ceramic lock pin 22 is positioned at ceramic ring 21, and rubber dust cap 1 is enclosed within on the fiber optical transceiver 2, forms confined space 4, keeps the cleaning of optical fiber ceramic lock pin 22 in processing procedure.But, use the rubber dust cap often to have following shortcoming: (1) rubber is easy to adhere to dust, easy cleaning not, the easy cleaning not of the dust on the inwall particularly, because air flow, the dust on the rubber dust cap inwall causes for the second time pollution probability than higher with air flow to the optical fiber ceramic lock pin.(2) after fiber optical transceiver is put on the rubber dust cap,, when environment temperature raise to produce thermal expansion, usually make the ejection of rubber dust cap and do not have protective effect because air is airtight in jack.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, and a kind of metal dust cap that is used for fiber optical transceiver is provided, and the dependability height can effectively prevent from high low temperature circulating treatment procedure the optical fiber ceramic lock pin to be polluted.
The technical solution adopted in the utility model is: a kind of metal dust cap that is used for fiber optical transceiver, comprise the cap body, the internal diameter of cap body inserts and is fixed with the dust cap lock pin, and the internal diameter of the external diameter of described dust cap lock pin and the ceramic ring of fiber optical transceiver is complementary and can forms and closely cooperates.
Adopt the metal dust cap of such scheme, because the cap body is a stainless steel material, the dust cap lock pin is a stupalith, thereby is difficult for the absorption dust, cleans easily.Because dust cap lock pin and ceramic ring form closely cooperates, thereby connect firmly, dustproof metal cap is difficult for coming off from fiber optical transceiver in high low temperature circulating treatment procedure, has improved the effect of protecting ferrule endface in the high low temperature circulating treatment procedure.

Description of reference numerals: rubber dust cap 1, fiber optical transceiver 2, ceramic ring 21, optical fiber ceramic lock pin 22, metal dust cap 3, cap body 31, dust cap lock pin 32, gas outlet 33, confined space 4.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figures 2 and 3, a kind of metal dust cap 3 that is used for fiber optical transceiver, comprise cap body 31, the internal diameter of cap body 31 inserts and is fixed with dust cap lock pin 32, and the internal diameter of the ceramic ring 21 of the external diameter of described dust cap lock pin 32 and fiber optical transceiver 2 is complementary and can forms and closely cooperates.Cap body 31 adopts stainless steel material usually, and dust cap lock pin 32 adopts stupalith, and its external diameter size forms interference fit with the internal diameter of the ceramic ring 21 of transceiver 2, so that can closely cooperate with ceramic ring 21.
In order to prevent that the dust in the process from entering the inwall of fiber optical transceiver, the openend of cap body (31) and the tangent formation confined space of fiber optical transceiver (2) end face (4).In order to prevent that the air in the confined space (4) from coming off because of thermal expansion makes dust cap, can set out gas port 33 at the openend of cap body (31) again, gas outlet 33 is groove or the shrinkage pool that connects along end face, and the gas outlet should be as much as possible little.
Claims (3)
1. metal dust cap that is used for fiber optical transceiver, comprise cap body (31), it is characterized in that, the internal diameter of cap body (31) inserts and is fixed with dust cap lock pin (32), and the internal diameter of the ceramic ring (21) of the external diameter of described dust cap lock pin (32) and fiber optical transceiver (2) is complementary and can forms and closely cooperates.
2. metal dust cap according to claim 1 is characterized in that, the openend of described cap body (31) and the tangent formation confined space of fiber optical transceiver (2) end face (4).
3. metal dust cap according to claim 2 is characterized in that, the openend of described cap body (31) has gas outlet (33).
