Inserting pin component of optical cable connector and tensile connecting structure of inserting pin component and optical cable

The invention discloses an inserting pin component of an optical cable connector and a tensile connecting structure of the inserting pin component and the optical cable. A conical surface with gradually reduced external diameter is arranged on the outer surface of the tail part of a rear sleeve of an inserting pin component; a conical sleeve of which an inner ring is in a conical surface closed structure is correspondingly sleeved on the conical surface; a screw nut is movably assembled on an outer ring of the conical sleeve; an axial meshed structure is arranged on the combining surface between the inner ring of the screw nut and the outer ring of the conical sleeve; screwing match structures are arranged on the inner wall at the front end of the screw nut and the outer wall of the rear sleeve; an aramid fiber exposed from the cutting position of the outer skin of the optical cable is clamped between the outer surface of the conical surface of the tail part of the rear sleeve and the inner ring of the conical sleeve; the aramid fiber, the conical sleeve and the rear sleeve are fixed into a whole by the function of screwing locked force between the screw nut and the rear sleeve; when the optical cable is pulled by external force, the pulling force is exerted on the conical sleeve and the rear sleeve by the aramid fiber, and a center optical fiber can not be pulled; when a flange or the rear sleeve of the inserting pin component is pulled, the whole optical fiber can be pulled to move by the aramid fiber, thereby being free from the damage of the center optical fiber by pulling and leading the installation of the inserting pin component to be more convenient.
