Description

Fabrication of a variable adapter for disconnection using a ferrule stub {Fabrication of a adapter for the optic line inspection using hetero ferrule stub}

The present invention relates to an apparatus for inspecting disconnection for detecting an abnormality of a multi-core optical connector cable line, and more specifically, an optical fiber connecting multi-core optical connector used in special fields such as MIL, aviation, and shipbuilding is an optical fiber used in general optical communication. Since the size and length of the connector is different and the connector structure is used in the plug and receptacle method, it is related to the adapter that can replace the tool for the inspection of wire disconnection according to the size of the ferrule or the sleeve of the optical connector.

The MIL Multi-core Optical Connector is mainly used for special equipment such as aircraft and ships, and it is a special environment for the transmission of control information and security data for sensitive equipment that requires minimization, light weight, precision, accuracy and stability. Connector for optical network systems. Here, the ferrule used in the MIL multi-core optical connector uses a MIL-STD standard of 1.25mm, 2.5mm optical communication ferrules and other special specifications of 1.6mm, 2.0mm ferrules.

In general, the inspection of the optical connector or the optical fiber can be performed with a simple inspection tool. However, in the case of using a special ferrule, it is not easy to combine with a general ferrule using a different standard, so a separate ferrule matching tool is required. Commercially available tools for inspection of wire disconnection are manufactured based on 1.25mm and 2.5mm ferrules, and therefore require adapters that are compatible with general standard ferrules and various special ferrules, and that are compatible with individual ferrules.

On the other hand, the replaceable adapter is a housing body (male, female), including a fixed ferrule stub (hetero ferrule stub) accommodating 2.5mm ferrules and 1.6mm, 2.0mm ferrules (hereinafter MIL ferrule) and a fixed tap, fixing them It has a built-in stop ring, and consists of a mating structure of flange holder for coupling between 2.5mm ferrule and MIL ferrule, flange holder including tap (male, female), sleeve alignment holder, and MIL ferrule sleeve. However, 2.5mm ferrules and MIL ferrules are different in size, resulting in different losses in alignment error when contacted by a common coupling method. The other standard ferrules and MIL ferrules are forcibly pressed and combined with each other, and a fiber is inserted into the inserted ferrules and fixed with epoxy to produce a release ferrule stub that is not affected by axial alignment error. In addition, it has a structure including a fixed portion, such as a Tap structure and a tap or stop ring to prevent the housing body from falling off to prevent shaking in the housing body of the flange at the time of coupling.

Therefore, the problem to be solved by the present invention is the convenience of detachable detachable ferrule stub using 2.5mm ferrules and MIL ferrules, and is not affected by axial misalignment during contact between ferrules through alignment keys with stub ferrules. Applicable, the connector shape of the portion to be contacted can be applied in the form of a sleeve as well as ferrule type.

The variable adapter for cross-sectional inspection of the present invention for solving the above problems consists of a first mating structure of a release ferrule stub inserted into a combination flange of different sizes of ferrules and a flange holder for fixing the first mating structure, and a first mating structure and an accommodating structure. And a secondary mating structure with the housing body for the measurement of the sleeved connector. In addition, in the case of the ferrule protruding to the outside rather than the sleeve type, the connector to be measured is configured by engaging the array sleeve holder.

In addition, the shape of the release ferrule stub described above can be easily assembled by replacing a ferrule having a rear end portion of the release ferrule stub according to the function and standard of the 2.5mm standard ferrule and the MIL ferrule.

In the present invention, the housing body (male) takes the form of a tap in the front portion, the rear end has a structure that is coupled to the housing body (female) and using a stop ring, male both ends of the housing body (male) It takes a tap, it can be configured to have a structure that combines the female tap in the interior of the housing (female). In addition, the rear end of the housing body and the tap of the array sleeve holder can take the form of a push and swing lock using a hold key and a groove.

According to the variable adapter for disconnection inspection using the release ferrule stub of this invention, the front end of the connector adapter of the part to which inspection light enters forms the 2.5 mm ferrule of a general optical communication standard in the combination flange by force fitting, The cross section forms a set of grooves that can accommodate the rear end of the flange to which the MIL ferrule is applied. The MIL ferrule flange is a device that can accommodate ferrules of various sizes. It is composed of SUS, and the MIL ferrule flange holder, male, female and flange holder (male, female) are combined to have a male optical connector. It can be useful for checking optical paths, and for checking optical paths with female optical connectors using MIL sleeves and array sleeve holders.
