As the cost of optical fiber continues to decrease, the optical fiber has become more and more in the field of communication. The more widely used. [0003] Fiber-coupled connectors play an important role in fiber-optic transmission. The quality of fiber-coupled connectors affects the efficiency of fiber-optic transmission. Referring to Figure 5, a prior art solution for a fiber-optic coupling connector. The fiber-coupled connector 10 is a one-piece, unitary structure having a blind hole 14 for receiving an optical fiber 12 that guides the optical lens 16 at the end of the fiber-coupled connector 10. Since the blind hole 14 is an elongated hole, the ratio of the radial dimension to the axial dimension is small. Therefore, the fiber-coupled connector 10 is liable to cause the following problems: First, when molding, the molding die corresponding to the blind hole 14 is inserted. The child is relatively slender, and Q is not easy to be demolded during demolding, and may even cause the mold in the mold to be damaged or broken during the drafting process and block the blind hole 14, thereby affecting the molding efficiency and product yield; second, when assembling The optical fiber 12 is not easy to be inserted into the blind hole 14, which affects the assembly efficiency. Thirdly, it is difficult to adjust the distance between the optical fiber 12 and the optical lens 16, so that it is difficult to obtain a better position of the port of the optical fiber 12 at the focus of the optical lens 16. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a fiber-optic coupling connector 098131807 which is simple in construction and can effectively improve the problems of the prior art fiber-optic coupling connector.

[0008] [0008] [0008] Compared with the slow technical solution, the present invention has the following advantages: The optical-combined connector of the present invention is a chimeric structure, which is manufactured by molding. 'After listening to the phenomenon that the two people are damaged or clogging blind holes during the drafting process, and the sharpness and product yield are expected. The fiber-optic light-weight connector of a 'combined structure is easy to assemble, which can improve the assembly efficiency. Thirdly, when the optical fiber is used in the connector, the distance between the optical fiber and the optical lens is conveniently adjusted, so that the better position of the optical fiber port at the focus of the optical lens can be obtained relatively easily.
