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
Technical field
The utility model relates to a kind of fiber adapter, particularly relates to a kind of 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 SC adapter generally is comprised of 2 shells, 2 lock cores, a sleeve pipe, cylindrical cavity is arranged in the lock core, two ends are with flange, during manufacturing sleeve pipe put into two lock cores, two end boss can position porcelain bushing, again lock core is put into two shells, have block in the shell and can block lock core, then by ultrasonic soldering 2 shells are 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 whole adapter is disintegrated.
2, when welding such as sound wave are crossed conference and are caused the powder that shell melts to clamp-on in two lock cores that link closely, or the block in the shell cracks, and can produce side force to two flexible jumpers when using for a long time, thereby it is excessive to produce loss.
3, 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.
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 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 is the inner cylinder cavity, the shell top is with flange, described shell has four sides, the first, the 3rd side is relative, and link to each other with the second, the 4th side, the first side has U-shaped groove, when fiber active linker inserts flexible jumper is positioned, the 234 side surface has the Spring Card locating slot, and the inner end in the second, the 4th side all has the wedge type projection of rake angle.
Preferably, described SC type integral fibre-optic adapter also comprises the integral type lock core, lock core have cylindrical cavity and on the top with flange, cylinder side has been worn two locating supports, described two supports match with two wedge type projections.
Preferably, the shell that is formed in one of described shell.
The beneficial effect that the utility model brings is: the parts that have are few, low cost of manufacture, installation are simple and easy, shell is one-body molded, can guarantee that product reliability can not produce scatter after long-time the use.

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.
To shown in Figure 5, the SC type integral fibre-optic adapter of present embodiment mainly comprises: shell, lock core 3 and porcelain bushing 7 such as Fig. 1.Described shell is formed in one, one end of shell is the axial inner cavity, the other end is the inner cylinder cavity, and the shell top is with flange 4, and described shell has four sides, the first, the 3rd side is relative, and link to each other with the second, the 4th side, the first side has U-shaped groove 1, when fiber active linker inserts flexible jumper is positioned, the end that the 234 side surface has Spring Card locating slot 2, the second, inside, the 4th side all has the wedge type projection 5 of rake angle; Described SC type integral fibre-optic adapter also comprises integral type lock core 3, lock core 3 have cylindrical cavity and on the top with flange 4, cylinder side has been worn two locating supports, described two locating supports 6 match with two wedge type projections 5.
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.
