Abstract

The utility model provides an LC duplex SC type integral optical fiber adapter. The integral optical fiber adapter comprises a shell, a lock core and a ceramic sleeve, wherein an axial inner cavity is arranged on one end of the shell, the integrally molded lock core is arranged on the other end of the shell, a cylindrical hollow cavity is arranged in the lock core, and a flange is arranged on the top of the hollow cavity. The manufacture cost is low, the mounting process is easy, the shell is integrally molded, so as to ensure the reliability of the product and prevent the product from being separated after long-time use, and moreover the risk in easy breakage of the ceramic sleeve is reduced.

Description

A kind of LC duplex SC type integral fibre-optic adapter

Technical field

The utility model relates to a kind of fiber adapter, particularly relates to a kind of LC duplex SC type integral fibre-optic adapter.

Background technology

Fiber adapter (having another name called ring flange), also be the joints of optical fibre, it is fiber active linker centering link, fiber active linker is usually located at the two ends of optical fiber, fiber adapter has two openings, two flexible jumpers are inserted respectively in the both ends open of fiber adapter, thereby realize two flexible jumper centerings are connected.

Existing LC duplex SC type adapter generally is comprised of 2 shells, 2 sleeve pipes, enclosure has the lock core with the shell one, cylindrical cavity, top are arranged with flange in the lock core, during assembling sleeve pipe is put into lock core, the flange of lock core is located sleeve pipe, then by ultrasonic soldering 2 shells is welding together.

Above-mentioned design has following problem,

1, cause easily during ultrasonic soldering between two shells of adapter extrapolability inadequate, the stress at two ends may make two shells separately when using for a long time, thereby makes whole adapter separately.

2, during ultrasonic soldering end face to play that easily soft flocks, end face weldering are hindered etc. bad, soft flocks may be called in the sleeve pipe after repeatedly plug was used, thereby two flexible jumpers can not directly be contacted, it is excessive to produce loss.

3, the about 0.19mm of the LC duplex general wall thickness of used LC porcelain bushing, sound wave cracks the porcelain bushing in the adapter or fragmentation easily during ultrasonic soldering, can produce the sleeve pipe fragmentation after long-time the use, affects life of product and reliability.

The utility model content

In order to overcome the technical matters that exists in the prior art, the utility model provides following technical scheme:

A kind of LC duplex SC type integral fibre-optic adapter, it comprises shell, lock core and porcelain bushing, and described shell one end is the axial inner cavity, and the other end has integrated lock core, and lock core inside has the cavity of column type, and the cavity top is with flange.

Preferably, described shell has four sides, the first, the 3rd side is relative, and link to each other with the second, the 4th side, the shell wedge type projection that has two symmetries with the outside, the second, the 4th side of lock core one end, first, second of the other end, the 4th side have the Spring Card locating slot, and the first, the 3rd side also has the lock core pilot hole.

Preferably, described lock core contains the cavity of two column types, has a rectangular parallelepiped column to separate between described two cavitys, and the column both sides have symmetrical lock core wedge type projection.

Preferably, described shell is formed in one and makes.

The beneficial effect that the utility model brings is: low cost of manufacture, simple and easy, shell is installed is one-body molded, can guarantee that product reliability can not produce separately after long-time the use, and reduce the breakable risk of porcelain bushing.

Embodiment

The below is to elaborating preferred embodiment of the present utility model by reference to the accompanying drawings, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model made more explicit defining.

Extremely shown in Figure 8 such as Fig. 1, a kind of LC duplex SC type integral fibre-optic adapter, it comprises shell, lock core and porcelain bushing, described shell one end is the axial inner cavity, the other end has integrated lock core, and lock core inside has the cavity 5 of column type, and cavity 5 tops are with flange 4.Described shell has four sides, the first, the 3rd side is relative, and link to each other with the second, the 4th side, the shell wedge type projection 1 that has two symmetries with the outside, the second, the 4th side of lock core one end, first, second of the other end, the 4th side have Spring Card locating slot 3, the first, the 3rd side also has lock core pilot hole 2.Described lock core contains the cavity 5 of two column types, has a rectangular parallelepiped column to separate between described two cavitys 5, and the column both sides have symmetrical lock core wedge type projection 6.Described shell is formed in one and makes.

Porcelain bushing 7 is packed into from cavity 5 one ends the lock core, position by 4 pairs of porcelain bushings 7 of flange, then lock core is pushed the end that fiber adapter has cavity 5, lock core wedge type projection 6 is stuck in the lock core pilot hole 2 of shell, namely forms the utility model LC duplex SC type integral fibre-optic adapter.

The above; it only is one of embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
