Embodiment Construction

[0012] The preferred embodiment of the present invention is given below.

[0013] The plastic optical fiber connector involved in the present invention is as figure 1 As shown, it includes a stem [11], a tapered nut [12], a buffer sleeve [13], a connection cap [14] and an adapter [15]. There is an axial through hole in the stem [11], the diameter of which can be inserted into the plastic optical fiber. , the other end is tapered with grooves on it. The conical nut [12] is hollow, the upper part has a conical inner surface, and the lower part is a cylindrical internal thread, which is sleeved on the outside of the stem [11]. [11] The grooves on the outer tapered surface can firmly fasten the optical fiber and the sheath on the outer tapered surface of the core post [11]. The adapter [15] is a transition piece with a cylindrical external thread and a flange, and its external thread is docked with the connecting cap [14]. The flange of the adapter [15] is used to fix on the in...

Abstract

A plastic connector for optical fibre and optical elements is composed of core pile, conic nut, buffer sleeve, connecting cap and adapter, and features that it is needed that the end of optical fibre to be connected must be conic. The tool for making said end of optical fibre formed conic is composed of electric heater, sleeve barrel, supporter, regulating nut, and die. Its advantages are simple method and high connection effect.

Description

technical field [0001] A simple optical cable home plastic optical fiber connector and the forming of the inverted tapered lens-shaped optical fiber end, which is used for connecting the single-core plastic optical fiber end to the user terminal, and to connecting with the light source, optical detector and other active devices and couplers, switches, wavelength division Connection of passive components such as multiplexers and attenuators. Background technique [0002] At present, various connectors have been disclosed in this technical field, which are divided into two categories, namely, quartz optical fiber connectors and plastic optical fiber connectors. The former is used for the connection of silica optical fibers. Since the core of the silica optical fiber is very thin, about 9 microns, in order to ensure its neutrality, thermal stability and motion stability during the connection process, the requirements for the material and processing accuracy of the connector ar...
