Compared with the prior art, the SC tail fiber adapter has the advantages of convenience for insertion and extraction, low insertion loss fluctuation, strong compressive strength and high mounting density, and mounting connection requirements are completely met.

Description

SC tail optical fiber adapter

Technical field

The utility model relates to a kind of SC tail optical fiber adapter.

Background technology

In the communications field; Optical fiber communication is widely used and develops, and very extensively, various terminal devices all need be connected with the optical cable tail optical fiber especially in the application of optical cable in LAN; Because the geometrical property and the optical characteristics of optical fiber; And transport property has very high requirement to the tail optical fiber coupling arrangement, and existing tail optical fiber is various informative, basically can dealing with various requirements.

Because the conventional adapter front opening is bigger, and is ineffective to fiber support, and; The inner tolerance clearance of conventional adapter is bigger, can not retrain optical fiber well, so; Conventional adapter is under bending and twisted state; Deformation ratio is more serious, has influence on the right alignment of butt joint optical fiber, and light transmissioning efficiency also descends and the light transmission instability to some extent.In addition, existing tail optical fiber adapter structure spare is many, and for guaranteeing the central aperture of each part, the precision of processing assembling is high, difficulty is big, and cost of goods manifactured is high, is unfavorable for mass production.

The utility model content

The utility model technical matters to be solved is to provide a kind of compact conformation, plug easy to operate to the above-mentioned state of the art, inserts the little SC tail optical fiber adapter of loss fluctuation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of SC tail optical fiber adapter is characterized in that comprising

Sleeve, axial hollow, front end has spacing muscle;

Plug, axial hollow, plug-in mounting is arranged in the aforesaid sleeve and leading section is limited in aforesaid spacing muscle;

Socket, axially hollow forms hollow channel, and the internal diameter of this hollow channel leading section is greater than the internal diameter of rearward end, and the leading section plug-in mounting of this socket is arranged at the rearward end of plug;

Lock pin, leading section are plugged in the aforesaid plug and stretch out sleeve, and the middle part has bulge loop, and rearward end is arranged in the aforesaid socket;

Pressure spring is sheathed on the rearward end of aforementioned lock pin and is positioned at socket; And

Sheath is assemblied in the rear end of aforesaid sockets.

Further, be provided with an aluminium hydraulic pressed connecting pipe in the front port of said sheath, described socket then is located in this aluminium hydraulic pressed connecting pipe.

Further, the outer wall of said plug has radially outward protruding projection, and accordingly, described sleeve leading section has with aforementioned projection and cooperates to limit the stopper slot that plug breaks away from sleeve backward.

Further, the leading section of said plug has the gear piece that is raised in outer wall, and described plug is assemblied under the state of sleeve, and aforesaid gear piece cooperates with spacing muscle and limits plug and breaks away from sleeve forward.

Compared with prior art, the advantage of the utility model is: plug easy to operately, it is little to insert loss fluctuation, and compressive strength is higher, and packing density is high, satisfies fully the connection needs are installed.Simultaneously, calibrate contraposition between each parts easily, greatly reduce the requirement of assembly precision, be beneficial to large-scale production.
