Description of the invention (1) Scope of the invention The present invention relates to a contact device for optical fibers, which can be connected to each other by using the contact device. BACKGROUND OF THE INVENTION Optical fiber contact devices have so far been manufactured in a very expensive manner, and in terms of size and weight, it is easy to cause fiber breakage when handling and stretching interconnected cables in confined pipes and pathways. . Contact devices are currently quite expensive because they consist of a large number of precision components. ^ SUMMARY OF THE INVENTION In an effort to simplify the manufacturing of optical fiber contact devices, there have been proposed 10 contact devices that, although containing only a few components, still meet the requirements of low attenuation for optical fiber signal transmission. Precision components for such contact devices, such as ferrules, are preferably standardized and produced by a number of companies in order to reduce the selling price. Other components can be manufactured using polymer materials in a body shape, which reduces the unit price very low. An important feature of the contact device of the present invention is that it is used with an identical contact device, so that the two contact devices can be connected to each other only by means of the guide sleeve at the end of the ferrule, without the need for an intermediary element. Another important feature is that the combination of the thread and the fastening surface of a contact device enables the contactor to be fixed to a stand by means of, for example, two nuts. This means that, for example, two optical fibers in a cable duct can be connected to each other using the same contact device, and the contact device 0 can also be easily mounted on a stand. The present invention will now be described in more detail with reference to the preferred embodiments and in conjunction with the accompanying drawings.

Description of the invention (3) When the device is touched, the thread 19 can also be used as a fastening surface. The housing 1 of the contact device 20 that can be mounted on the base has a narrow section, which forms a protector 2 to prevent breakage, and is used to protect the optical fiber 4 surrounded by the optical fiber protector 3. The housing 1 also has The function of enclosing an optical fiber ferrule, which includes a narrow cylindrical part 7 for supporting the optical fiber 4, a larger cylindrical part 5 and a flange 6, and the naked optical fiber 4 is firmly bonded or otherwise It is fixed at this narrow part 7 and the optical fiber sheath is firmly bonded, clamped or otherwise fixed on the larger cylinder 5. There is also a coil spring 8 acting between the left end face 26 of the flange and the end face 9 of the contact device 20 which can be mounted on the base for pushing the ferrule toward a contact area. A similar coil spring 23 is applied to the ferrule 24. Therefore, the springs 8 and 23 can apply a fixed outward pressure to the two ferrules, thereby providing a ground, polished or otherwise treated and contacted contact device 20 that can be mounted on the base and in the contact device 21. The contact area of the interface 16 between the fiber ends has good optical contact. By screwing a tubular guide sleeve 10 over the narrow parts 7 and 24 facing each other on the respective ferrules, the narrow cylindrical part 7 of the ferrule in the contact device 20 that can be mounted on the base will be guided to contact The ferrule in the device 21 has a narrow cylindrical portion 24. The base-mountable contact device 20 further includes at least one fastening shoulder 15 having an angled fastening surface 17 thereon, and the contact is fastened and supported by using the angled fastening surface 17. A reverse similar buckling shoulder 14 on the device 21 can be used together with the buckling shoulder 14 of the contactor 21. The step of attaching the contact device 21 to the contact device 20 which can be mounted on the base is to first place the guide sleeve 10 on the ends of the two ferrules containing the optical fiber, and then

V. Description of the invention (4) A contact device 21 is pushed toward the contact device 20 which can be mounted on the base until one end face 18 of the contactor 21 Push against one end surface 22 of the contact device 20, and the ends of the two optical fibers in the guide sleeve 10 contact each other, and then rotate the contact device 21 clockwise until the two fastening shoulders touch. Since the angled fastening surfaces of the fastening shoulders 14 and 15 are opposite and oppositely positioned, the force exerted by the spring after the contact device 21 is released will move the two angled fastening surfaces to Positions that fit into each other while maintaining contact between the fiber ends in the two ferrule ends. The method for removing the contact device 21 from the contact device 20 that can be mounted on the base is to press the contactor 21 to the contact device 20 that can be mounted on the base to the end face 1 of the contact device 21 8 is pushed to the end surface of the contact device 20 and the fastening surfaces are separated from each other. Then rotate the contactor 21, for example, 90 degrees counterclockwise, so that the fastening shoulder 15 of the contact device 20 that can be mounted on the base does not pass through the fastening shoulder 14 of the contact device 21, and then the contact device is turned toward Pull right to separate the optical contact between the fiber ends at interface 16. At this time, in the contact device 20 and the contact device 21 that can be mounted on the base, the springs 8 and 23 are applied to the respective ferrules. The spring pressure on the spring will decrease. It should be understood that the present invention is not limited to the specific exemplary embodiments described above, and some modifications can be made, and these modifications are within the scope of the appended patent application.
