Description
Technical field
The present invention relates to the technical field of the mechanical performance 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 used in fiber to the home (FTTH) engineering, and this product is mainly used on the long range propagation of optic communication, the mechanical performance index of product is required very high, and product machinery index can not be guaranteed by the production technology of routine.
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, when oversheath is crimped after part is pressed on the caudal peduncle of lock pin, oversheath is easy to again come off from the caudal peduncle of lock pin in use, and the synthetic fibre yarn that spins in optical cable can only be pressed on caudal peduncle by crimp, thus causing that the resistance to tension of ST type light wire jumper after assembling and torsion capacity can not be up to state standards requirement, have a strong impact on the service life of product, therefore, this ST type light wire jumper is not promoted the use of.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of compact conformation, mechanical strength are high, long service life, assembling are easy to a kind of ST type optical patchcord and assembly technology thereof.
The purpose of the present invention is achieved through the following technical solutions: a kind of ST type optical patchcord, it includes 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, it is enclosed with tight tube fiber that diameter is 0.9mm in oversheath and multiple spins synthetic fibre yarn, and each one end spinning synthetic fibre yarn is all exposed to outside sheath, tight tube fiber is inserted in the jack of ceramic contact pin through caudal peduncle, tight tube fiber is cased with pressure rivet, one end of pressure rivet is arranged in caudal peduncle, the other end of pressure rivet is arranged in oversheath, the described synthetic fibre yarn that spins outside sheath that is exposed to all crimps between caudal peduncle and crimp, oversheath is crimped between pressure rivet and crimp.
The length of described crimp is more than pressure rivet.
The diameter of described tight tube fiber (6) is 0.9mm.
A kind of assembly technology of ST type optical patchcord, it comprises the following steps:
S1, pressure rivet is enclosed within tight tube fiber and makes one end of pressure rivet form interference fit with oversheath;
After S2, assembling, first the head end of tight tube fiber is initially inserted in caudal peduncle, then inserts it in the jack of ceramic contact pin;
After S3, assembling, the other end of pressure rivet is formed interference fit with caudal peduncle;
After S4, assembling, crimp is enclosed within oversheath from the afterbody of oversheath;
After S5, assembling, crimp is slided to lock pin direction, makes each synthetic fibre yarn that spins being exposed to outside sheath all be crimped between caudal peduncle and crimp, and make oversheath be crimped between pressure rivet and crimp.
The invention have the advantages that one end of the pressure rivet of (1) 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 by pressure rivet tightly be against between crimp and pressure rivet, thus greatly improving the mechanical strength of this ST type optical patchcord, resistance to tension brings up to 70N, exceed national standard 20N, torsion capacity brings up to 50N, exceed national standard 25.3N, and extend this ST type optical patchcord service life, ensure that the stability of product quality, solve oversheath due to too thick easily from the phenomenon come off caudal peduncle, ensure that the crimping spinning synthetic fibre yarn simultaneously. (2) assembly technology of the present invention is very simple, facilitates the operation of workman, and improves efficiency of assembling.
