Technical field
The present invention relates to the technical field of the mechanical property of improving ST type light wire jumper, particularly a kind of ST type optical patchcord and assembly technology thereof.
Background technology
ST type light wire jumper is a large amount of products that use in Fiber to the home (FTTH) engineering, and this product is mainly used in the long Distance Transmission of optical communication, mechanical performance index requirement to product is very high, and conventional production technology can not be guaranteed to product machinery index.
ST type light wire jumper is made up of lock pin, crimp and optical cable, the oversheath of existing optical cable is due to too thick, after oversheath is crimped on the caudal peduncle that part is pressed in lock pin, oversheath is easy to the caudal peduncle from lock pin again and comes off in use, and crimp can only be pressed in the synthetic fibre yarn that spins in optical cable on caudal peduncle, thereby cause the requirement that can not be up to state standards of the resistance to tension of ST type light wire jumper after assembling and torsion capacity, have a strong impact on the serviceable life of product, therefore, this ST type light wire jumper is not promoted the use of.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of compact conformation, physical strength are high, long service life, assembling be easy to a kind of ST type optical patchcord and assembly technology thereof.
Object of the present invention is achieved through the following technical solutions: a kind of ST type optical patchcord, it comprises lock pin, oversheath, pressure rivet and crimp, described lock pin is made up of ceramic contact pin and caudal peduncle, caudal peduncle is connected with ceramic contact pin, in oversheath, be enclosed with tight tube fiber and multiple synthetic fibre yarn that spins that diameter is 0.9mm, and each one end of spinning synthetic fibre yarn is all exposed to oversheath outside, tight tube fiber is in caudal peduncle is inserted into the jack of ceramic contact pin, on tight tube fiber, cover has pressure rivet, one end of pressure rivet is arranged in caudal peduncle, the other end of pressure rivet is arranged in oversheath, described be exposed to the spinning between the equal crimping caudal peduncle of synthetic fibre yarn and crimp of oversheath outside, oversheath is crimped between pressure rivet and crimp.
The length of described crimp is greater than pressure rivet.
The diameter of described tight tube fiber (6) is 0.9mm.
An assembly technology for ST type optical patchcord, it comprises the following steps:
S1, pressure rivet is enclosed within on tight tube fiber and makes one end of pressure rivet and oversheath forms interference fit;
After S2, assembling, first the head end of tight tube fiber is first inserted in caudal peduncle, then is inserted in the jack of ceramic contact pin;
After S3, assembling, the other end of pressure rivet and caudal peduncle are formed to interference fit;
After S4, assembling, crimp is enclosed within oversheath from the afterbody of oversheath;
After S5, assembling, crimp is slided to lock pin direction, the each synthetic fibre yarn that spins that is exposed to oversheath outside is all crimped between caudal peduncle and crimp, and oversheath is crimped between pressure rivet and crimp.
The present invention has the following advantages: one end of (1) pressure rivet of the present invention is arranged in caudal peduncle, the other end of pressure rivet is arranged in oversheath, oversheath is crimped between pressure rivet and crimp, therefore, and the oversheath of pressure rivet contact portion is by pressure rivet being against between crimp and pressure rivet tightly, thereby improve greatly the physical strength of this ST type optical patchcord, resistance to tension is brought up to 70N, exceed national standard 20N, torsion capacity is brought up to 50N, exceed national standard 25.3N, and extend this ST type optical patchcord serviceable life, ensure the stability of product quality, solve oversheath due to the too thick phenomenon easily coming off from caudal peduncle, ensured to spin the crimping of synthetic fibre yarn simultaneously.(2) assembly technology of the present invention is very simple, has facilitated workman's operation, and has improved efficiency of assembling.
