The utility model content

For the problems referred to above, the utility model aims to provide a kind of SC type optical fiber cable connector that can assemble at the scene fast and be installed in the wall box.

For realizing this technical purpose, scheme of the present utility model is: a kind of optical fiber leads directly to SC type optical fiber cable connector, comprise ferrule assembly, be nested with inside casing cover, the optical cable wire casing on ferrule assembly and be built in gathering sill in the optical cable wire casing, described ferrule assembly is the short-tail handle structure, described gathering sill adopts single continuous minor structure, the bell-mouth structure of air that the insertion end of this groove is inserted for ease of optical fiber.

As further improvement, the integrated unitor that is connected with ferrule assembly that is provided with on the described optical cable wire casing.

As further improvement, described connector comprises that also one is sleeved on the outer frame set that inside casing puts, and the side of this outer frame set is provided with antiskid groove.

As further improvement, the end of described optical cable wire casing is provided with optical cable and compresses screw, and forcing screw cooperates this screw by optical cable clip fixed light cable, is reserved with the fibre-optical bending space between described ferrule assembly and the compression screw.

This programme reduces the physical dimension of joint with the optical fiber direct-passing mode, simultaneously preset coupling oil in optical-fibre channel, the fiber end face after the finishing cutting, solved fiber end face since the cutting out-of-flatness and can not be effectively with the technical barrier of external fiber alignment; Simultaneously, the total length of joint shortens to below the 38mm, has solved after erection joint in the 86*86mm standard wall box, and the afterbody optical cable can freely coil in the wall box.Avoided because joint is long, afterbody optical cable bending radius is too small, affects the normal connection of joint; In addition, optical fiber directly penetrates joint through behind the ends cutting, directly dock with external connector, lack a contact than pre-buried optical-fiber type joint, reduced the light energy losses of connector when connecting, and can observe directly optical fiber and penetrate into the precalculated position, guarantee that optical fiber is with the connection of external optical fiber within the walls.
