Abstract:
1. An optical coupling device, comprising: an optical coupling member having at least a lens portion, a reflective face, and a first under positioning portion, wherein an optical signal transmits into the optical coupling member via the lens portion, and then is reflected by the reflective face to leave the optical coupling member, or an optical signal transmits into the optical coupling member, and then is reflected by the reflective face to leave the optical coupling member via the lens portion; an optical-electrical converting module, which is beside the optical coupling member, having a substrate, a base, and an optical-electrical converter, wherein the base is made of an insulating material and is provided on the substrate; the base has a receiving portion and a second under positioning portion; the optical-electrical converter is received in the receiving portion of the base to receive an electrical signal and convert the electrical signal into an optical signal, or receive an optical signal and convert the optical signal into an electrical signal, and the second under positioning portion engages the first under positioning portion of the optical coupling member to connect the optical-electrical converting module to the optical coupling member and make the optical-electrical converter face the optical coupling member; at least an optical fiber having an end facing the optical coupling member, wherein the optical coupling member is between the optical-electrical converting module and the optical fiber; the optical fiber transmits an optical signal from outside to the optical coupling member, or receives an optical signal from the optical coupling member and transmits the optical signal to outside; and the lens portion of the optical coupling member has a first lens portion and a second lens portion; the first lens portion is at a side of the optical coupling member which faces the optical-electrical converting module; the first under positioning portion and the first lens portion are on the same side; and the second lens portion is at a side of the optical coupling member which faces the optical fiber.
