Background technology
The joints of optical fibre are the maximum optical passive components of use amount that constitute optical fiber telecommunications system.Since the nineties, having formed is FC, ST and three kinds of prevailing situations of connector of SC type of Primary Component with the ceramic contact pin, and aspect the optical cable backbone net, FC connector still is to use maximum.But present disclosed plastic optical fibre connector, mainly by ceramic insertion core, Plug base, preceding adapter sleeve, spring, back adapter sleeve and protecting pipe constitute, ceramic insertion core is installed on the Plug base, preceding adapter sleeve is sleeved on ceramic insertion core and is positioned on the Plug base, this ceramic insertion core is located by preceding adapter sleeve, spring is arranged between Plug base and the back adapter sleeve, the axle collar of back adapter sleeve is provided with the tooth of even cloth, and match with depression on the preceding adapter sleeve, adapter sleeve can not freely rotate with the back adapter sleeve before making, gland is installed on the adapter sleeve of back, at last protecting pipe is installed on the gland oversheath.The preceding adapter sleeve of this structure adopts tooth engaging conformation with the syndeton of back adapter sleeve, complex manufacturing technology not only, and the cost of manufacture height, and also because of both contacts area are little, locking effect is not good.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, coupling mechanism force height, plastic optical fibre connector easy for installation.
The utility model is that the technical scheme that achieves the above object is: a kind of plastic optical fibre connector, it is characterized in that: comprise ceramic insertion core, adapter sleeve, the lock pin tailstock, spring, pressure welding case, big gland and little gland, the internal partition that ceramic insertion core passes adapter sleeve is connected with the lock pin tailstock, the middle rear side of adapter sleeve is provided with two above axial notch, adapter sleeve is provided with socket on the jacket wall between two axial notch, pressure welding case is enclosed within on the lock pin tailstock and is positioned at the mounting hole of adapter sleeve, convex tendon on the pressure welding case jacket wall is arranged in the socket of adapter sleeve, spring is arranged in the spring eye of the shaft shoulder of lock pin tailstock and pressure welding case, the dividing plate of lock pin tailstock and adapter sleeve joins, be the rear portion that step-like big gland front portion is crimped on pressure welding case, little gland is crimped on the path place at big gland rear portion.
Plastic optical fibre connector of the present utility model is provided with axial notch and socket radially on adapter sleeve, make adapter sleeve become ringfeder formula structure, especially the convex tendon on the pressure welding case jacket wall and being connected in the socket on the adapter sleeve, pressure welding case is locked mutually with adapter sleeve and connect, rational in infrastructure, not only be of value to the cooperation each other of each part, and increased the contact area of joint face between adapter sleeve and the pressure welding case, can reach the effect of reliable locking.The utility model is owing to adopt the plug-in syndeton, and the two crimping structures by big gland and little gland, and is not only easy for installation, reduces cost, and can fix reliably optical fiber.
