Abstract:
1. A method for manufacturing a one-piece LC type optical fiber adapter comprising the step of: (1) providing a main body having an axial cavity, which is defined by a top side-wall, a bottom side-wall, a right side-wall, and a left side-wall; (2) dividing the axial cavity into two halves through a compartment wall, which is parallel to the right side-wall and left side-wall and connected with the top side-wall and bottom side-wall and has a surface; (3) forming the half of the axial cavity, a right axial cavity, through the top side-wall, bottom side-wall, compartment wall, and right side-wall, wherein a first right opening and a second right opening are formed at the two ends of the right axial cavity respectively; (4) forming the other half of the axial cavity, a left axial cavity, through the top side-wall, bottom side-wall, compartment wall, and left side-wall, wherein a first left opening and a second left opening are formed at the two ends of the left axial cavity respectively; (5) forming a pair of tabs on the exterior of the main body, wherein the one tab is on the right side-wall and the other tab is on the left side-wall; (6) forming a pair of parallel ridges on the inner surface of the bottom side-wall of the axial cavity of the main body so as to define a groove, wherein the ridges and the groove are perpendicular to the bottom side-wall and divide the compartment wall into two halves, the groove being located at the middle between the first openings and the other middle between second openings of the main body; (7) forming two grooves on the right side-wall and left side-wall respectively, wherein the two grooves are collinear with the groove; (8) forming four pairs of protrusions, wherein the first pair of protrusions are at the locations near the first right opening on the joint of the right side-wall with the bottom side-wall and on the joint of the compartment wall with the bottom side-wall, the second pair of protrusions being at the locations near the first left opening on the joint of the left side-wall with the bottom side-wall and on the joint of the compartment wall with the bottom side-wall, the third pair of protrusions being at the locations near the second right opening on the joint of the right side-wall with the bottom side-wall and on the joint of the compartment wall with the bottom side-wall, and the fourth pair of protrusions being at the locations near the second left opening on the joint of the left side-wall with the bottom side-wall and on the joint of the compartment wall with the bottom side-wall; (9) forming an access opening on the top side-wall, wherein the location of the access opening is corresponding to the two tabs; (10) providing two inner housing halves that can be inserted into the axial cavity of the main body through the access opening, wherein the two inner housing halves are identical, each half comprising at least two hollow cylinders, a flange located at the two ends of the same side of the cylinders, the thickness of the two flanges of combining the two inner housing halves being equal to the widths of the grooves; (11) providing two hollow sleeves, wherein the two cylinders of each of the inner housing halves are coaxial in the main body and define two cylinders, and the two hollow sleeves being accommodated in the cylinders respectively; (12) combining the inner housing halves; (13) disposing the combined inner housing halves in the main body through aligning the flange of the inner housing half with collinear grooves; and (14) integrating a cover to the access opening of the main body, wherein the cover comprises a bottom surface, the surface of the compartment wall being firmly attached to the bottom surface.
