Description

The SC type joints of optical fibre

Technical field

The utility model belongs to technical field of optical fiber communication, is specifically related to a kind of SC type joints of optical fibre.

Background technology

Along with the development of optical communication technique, the joints of optical fibre for fibre junction are also widely used. the SC type joints of optical fibre occurred in existing market, its structure generally includes shell, fixing headgear, ceramic insertion core, plug core tail handle, spring, protective casing, when carrying out optical fiber and install, mobile for preventing optical fiber from occurring in ceramic insertion core, need optical fiber and corresponding ceramic insertion core to be fixed together by caking agent, optical fiber can applied pulling force effect by under external force state by optical cable, for avoiding causing ferrule assembly to occur moving axially because ferrule assembly is formed optical fiber pulling force effect, usually can have more than needed in junctor one section of optical fiber when assembling, when tail optical fiber is applied pulling force by optical cable, the effect of pulling force buffering is played by optical fiber more than needed, but, in practical set process, due to technician's operate miss, the optical fiber excess length of tail optical fiber arranges shorter sometimes, the pulling force from optical cable cannot be offset, make the optical fiber still can by plug core tail handle compression spring, the insertion core end face of another junctor in the end face of ceramic insertion core and adapter is caused to depart from, affect the normal transmission of signal, even cause the phenomenon that Optical Fiber Transmission is interrupted, and optical cable adopts pressure ring to fix, fixing cumbersome, the used time is longer, is unfavorable for improving output.

Practical novel content

The utility model technical issues that need to address are to provide that a kind of structure is simple, optical fiber is easy to fixing, and ceramic insertion core not easily loosens, the stable working state SC type joints of optical fibre.

For solving the problem, technical solution adopted in the utility model is:

A kind of SC type joints of optical fibre, comprise spring, sleeve pipe, optical cable is locked, ceramic insertion core, plug core tail handle and optical cable, described plug core tail handle head end is annular boss structure, the tail end of ceramic insertion core is fixed on plug core tail handle head, spring is enclosed within plug core tail handle afterbody, and the annular boss of plug core tail handle head is withstood in one end of spring, spring the other end insertion sleeve pipe also withstands the step in sleeve pipe, the tail end outer side of described sleeve pipe arranges screw thread, optical cable lock is by internal thread and telescopic joint, the cavity of described optical cable in the middle of cable lock withstands plug core tail handle tail end, the fibre core of optical cable wears the optic fibre hole into ceramic insertion core, described optical cable lock is made up of lock body and lock cap, described lock body inner portion face is arranged and telescopic joint internal thread, the outside screw that lateral tail face is arranged with lock cap is connected, tail end is the bar shaped tooth with certain length evenly distributed in annular.

Further; the utility model also comprises the protective sleeve and shell that rear end is sheathed on the fixing headgear of bushing head, front end sleeve is located at outside optical cable lock and optical cable; the aft end face of described fixing headgear connects with the front end face of protective sleeve, and described shell is sheathed on outside the leading section of fixing headgear and protective sleeve.

The useful effect adopting technique scheme to produce is: the fixing mode of the utility model optical cable adopts cable lock to replace pressure ring to fix, fixation is reliable, time optical cable under tension time, optical fiber more than needed can offset deformed in tension, the insertion core end face of another junctor in the end face of ceramic insertion core and adapter can not be departed from, communicating interrupt can not be caused.
