Abstract
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.
Description
Technical field
The present invention relates to fiber optic cable communications and use the optical connector technical field, especially a kind of contact pin parts of optical connector and with the syndeton of optical cable.
Background technology
Existing optical connector is made up of plug and socket; Be equipped with in the plug and socket with optical cable in the contact pin parts that are connected of optical fiber, the contact pin parts comprise with optical fiber and directly dock contact pin and the contact pin annex that contacts that the material of contact pin and optical fiber is all relatively more fragile; Therefore sealing and the Fixed Design to contact pin and optical fiber is most important in the optical connector; And the contact pin annex in the existing contact pin parts be mainly used in plug the jack of socket insulator is connected, lack the fixing tensile structure that reaches between contact pin parts itself and the optical cable, the bearing that has optical connector and optical cable now plug the afterbody of Socket casing; Its fixed form is generally the aramid fiber in the pressure welding case crimping optical cable; Owing to will take into account the fixing of grafting and optical fiber, cause the complicated and difficult installation of optical connector shell structure, it is stable to be difficult to also guarantee that contact pin is connected with optical cable; More existing in addition optical connectors and extraneous seal protection mainly are present in being connected on the housing of plug and socket; And the contact pin parts be directly installed on plug in the mounting hole of socket insulator; Both faying faces lack seal protection; This also causes the optical connector shell structure complicated, is difficult to also guarantee that the sealing of contact pin parts is tight.
Summary of the invention
The object of the present invention is to provide a kind of contact pin parts of the optical connector that can be connected with the direct tension of optical cable, the syndeton that provides a kind of contact pin parts and the direct tension of optical cable to be connected simultaneously.
Technical scheme of the present invention is: the contact pin parts of optical connector and the tensile connecting structure of optical cable; The contact pin parts of this structure comprise contact pin and the back cover that supplies optical cable to insert; Central optical fiber in the optical cable is docked with contact pin; Have aramid fiber between the crust of optical cable and the central optical fiber, the outside surface of the back cover afterbody of said contact pin parts has the conical surface that external diameter diminishes gradually, and correspondence is set with the tapered sleeve that inner ring is a conical surface closing in structure on this conical surface; Activity is equipped with nut on the tapered sleeve outer ring; The faying face of nut inner ring and tapered sleeve outer ring is provided with axial occlusion structure, and the front inner wall of nut is provided with the fit structure that spins with back cover outer wall, and optical cable penetrates in the cover of back through tapered sleeve; The aramid fiber that optical cable crust cut-off part exposes is installed between the conical surface outside surface and tapered sleeve inner ring of back cover afterbody, and aramid fiber, tapered sleeve, back cover are fixed as one by the nut and the coupling mechanism force effect that spins of back cover.
Axial occlusion structure on the faying face of described nut inner ring and tapered sleeve outer ring be by turn edge on the nut inner ring that fastens with the tapered sleeve outer ring on outer turning edge constitute.
Simultaneously; Technical program of the present invention also lies in having adopted a kind of ferrule of optical fiber connector parts, comprise contact pin, contact pin is inserted in the front end oral area of ring flange; The ring flange rear end is connected with the back cover; The outside surface of back cover afterbody has the conical surface that external diameter diminishes gradually, and correspondence is set with the tapered sleeve that inner ring is a conical surface closing in structure on this conical surface, and activity is equipped with nut on the tapered sleeve outer ring; The faying face of nut inner ring and tapered sleeve outer ring is provided with axial occlusion structure, and the front inner wall of nut is provided with the fit structure that spins with back cover outer wall.
Axial occlusion structure on the faying face of described nut inner ring and tapered sleeve outer ring be by turn edge on the nut inner ring that fastens with the tapered sleeve outer ring on outer turning edge constitute.
Be fixed with a plurality of O-ring seals on the outer ring of said ring flange vertically side by side.
Be provided with a plurality of ring grooves on the outer ring of said ring flange vertically side by side, spiral-lock O-ring seals in each ring groove.
Contact pin parts of the present invention in use; Aramid fiber between optical cable crust and the optical fiber is installed between the conical surface outside surface and tapered sleeve inner ring of back cover afterbody; And put after nut is screwed in; When screwing nut, nut can promote the male cone (strobilus masculinus) compression fit of inner conical surface with the back cover of tapered sleeve, thereby aramid fiber, tapered sleeve, back cover are fixed as one.When optical cable receives external force when pulling, motive force through aramid fiber be applied to tapered sleeve, after put, and can not affect central optical fiber; When the ring flange of pulling contact pin parts or back cover, can affect whole optical cable to move, and needn't worry can central optical fiber be drawn badly, also make the contact pin parts easier for installation through aramid fiber.
In addition, the ring flange of contact pin parts of the present invention is provided with O-ring seals, like this contact pin parts and plug mounting hole in the socket insulator when being connected, O-ring seals can carry out seal protection to the ring flange inside of contact pin parts.
