Abstract

An LC tail fiber adapter comprises a sleeve (1), a socket (4), an inserted core (2), a pressure spring (3) and a sheath (5), wherein the socket (4) is hollow in the axial direction to form a hollow channel, internal diameter of a front end of the hollow channel is greater than the internal diameter of a back end. A front end of the socket (4) is inserted in a back end of the sleeve (1). A front end of the inserted core (2) is inserted in the sleeve (1) and protruded a front surface of the sleeve (1) and a back end is arranged the front end of the socket (4). Compared with the prior art, the LC tail fiber adapter in the utility model is advantaged in that plugging and unplugging operation is convenient, fluctuation of insertion loss is small, compressive strength is high, installation density is high and the tail fiber adapter completely satisfies requirement of installation connection.

Description

LC tail optical fiber adapter

Technical field

The utility model relates to a kind of 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 LC 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 LC tail optical fiber adapter is characterized in that comprising

Sleeve, axially hollow;

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 sleeve;

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

Pressure spring is sheathed on the rearward end of aforementioned lock pin and is limited in the socket leading section; And

Sheath is assemblied in the rear end of aforesaid sockets.

Further, the outer wall of said socket leading section extends radially outwardly and is provided with projection, and accordingly, described sleeve forms the spacing hole that supplies aforementioned projection setting and then spacing socket.

Further, the middle part of said socket has the push stopping part that offsets with the sleeve rear end face.

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, parts are less, and calibration contraposition easily between each parts, greatly reduce the requirement of assembly precision, are beneficial to large-scale production.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the LC tail optical fiber adapter in the present embodiment comprises sleeve 1, socket 4, lock pin 2, pressure spring 3 and sheath 5.

Sleeve 1 axial hollow, socket 4 axial hollows form 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 4 is arranged at the rearward end of sleeve 1; Lock pin 2 leading sections are plugged in the sleeve 1 and stretch out the front end face of sleeve 1, and the middle part has bulge loop 21, and rearward end is arranged at the leading section of socket 4.

Pressure spring 3 is sheathed on the rearward end of lock pin 2 and is limited in socket 4 leading sections, and sheath 5 is assemblied in the rear end of aforesaid sockets 4.

Further, the outer wall of socket 4 leading sections extends radially outwardly and is provided with projection 41, and accordingly, sleeve 1 forms the spacing hole 11 that supplies projection 41 settings and then spacing socket.The middle part of socket 4 has the push stopping part 42 that offsets with sleeve 1 rear end face.
