Description
Technical field
The present invention relates to optical fibre coupling device technical field, particularly a kind of SC type joints of optical fibre.
Background technology
Along with the development of optical communication technique, light entering and copper back, fiber to the home are widely used, and the joints of optical fibre are also widely used among continuing of optical fiber.The joints of optical fibre can be divided into by connector version: FC, SC, ST, LC, D4, DIN, MU, MT etc.The SC type joints of optical fibre occurred in the market, its structure generally includes package casing, cover headstock, first lock pin, second lock pin, metal caudal peduncle, balancing spring, supporting base, beam ring nut, and gum cover pipe, described pullover cover for seat to be located in described package casing and with package casing snap-fit engagement, the end of described first lock pin and the second lock pin is located in described metal caudal peduncle to plug-in mounting, and make the first lock pin by bonding agent, second lock pin and metal caudal peduncle are fixed as one formation ferrule assembly, metal tail sleeve is located in described cover headstock, described supporting base is sheathed in package casing and its front end and cover headstock snap-fit engagement, described balancing spring is connected with between described metal caudal peduncle and supporting base, described beam ring spiro cap is arranged in the tail end of supporting base, the front end sleeve of described gum cover pipe to be located in package casing and to be connected with beam ring its thread.Pre-buried optical fiber is penetrated in first lock pin during use, tail optical fiber is penetrated in second lock pin, wherein said tail optical fiber inserts in the second lock pin after penetrating gum cover pipe, beam ring nut, supporting base successively, is intercoupled, thus complete the transmission of light signal by the end face of tail optical fiber and pre-buried optical fiber.
But, the defect of the above-mentioned SC type joints of optical fibre is: first, when carrying out optical fiber and installing, mobile for preventing optical fiber from occurring in lock pin, need by bonding agent, optical fiber and corresponding lock pin to be fixed together, due to the first lock pin of the above-mentioned joints of optical fibre, second lock pin and metal caudal peduncle are fixed as one by bonding agent when mounted, and optical cable and tail optical fiber link together, optical cable can apply pulling force effect to tail optical fiber by under external force state, for avoiding because tail optical fiber causes ferrule assembly to occur moving axially to ferrule assembly formation pulling force effect, therefore when assembling, one section of optical fiber section of having more than needed can be set in connector usually, when optical cable applies pulling force to tail optical fiber, the effect of pulling force buffering is played by the optical fiber section of having more than needed, but, in practical set process, due to technician's operate miss, the optical fiber of tail optical fiber segment length of having more than needed arranges shorter sometimes, the pulling force from optical cable cannot be offset, make tail optical fiber still can compress described balancing spring by metal caudal peduncle, the first lock pin is caused to be synchronized with the movement with metal caudal peduncle, and then cause the insertion core end face of another connector in the end face of the first lock pin and adapter to depart from, affect the normal transmission of signal, even cause the phenomenon that Optical Fiber Transmission is interrupted, the second, because the first lock pin and metal caudal peduncle are linked together by bonding agent, when connector frequently plugs, easily cause between the first lock pin and metal caudal peduncle and occur vertically loosening phenomenon, affect the normal use of connector.
