Abstract
The utility model discloses a contact pin part of a fiber connector which includes a contact pin; the contact pin is arranged in the opening part at the front end of a flange disk; the outer ring of the flange disk is fixed with a plurality of O-shaped seal rings in parallel along the coaxial direction. The contact pin part is provided with the O-shaped seal rings on the flange disk; in this way, when the contact pin part is connected with a mounting hole in the isolator of a plug/socket, the O-shaped seal rings can carry out seal production on the inside of the flange disk of the contact pin part.
Description
Technical field
The utility model relates to fiber optic cable communications optical connector technical field, especially a kind of contact pin parts of optical connector.
Background technology
Existing optical connector is made up of plug and socket, be equipped with the contact pin parts that are connected with optical fiber in the optical cable in the plug and socket, the contact pin parts comprise with optical fiber and directly dock contact pin and the contact pin annex that contacts, 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 be connected, lack fixing and tensile structure between contact pin parts itself and the optical cable, the bearing of existing optical connector and optical cable 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 optical connector shell structure complexity, and difficulty is installed, and 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 optical connector shell structure complexity, is difficult to also guarantee that the sealing of contact pin parts is tight.
The utility model content
The purpose of this utility model be to provide a kind of and optical connector plug tight contact pin parts of mounting hole sealing in the socket.
The technical solution of the utility model is: a kind of ferrule of optical fiber connector parts, comprise contact pin, and contact pin is inserted in the front end oral area of ring flange, is fixed with a plurality of O-ring seals on the outer ring of described ring flange vertically side by side.
Be provided with a plurality of ring grooves on the outer ring of described ring flange vertically side by side, spiral-lock O-ring seals in each ring groove.
The ring flange rear end of described contact pin parts is connected with the back cover, the outside surface of back cover afterbody has the conical surface that external diameter diminishes gradually, 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.
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 and the tapered sleeve outer ring on outer turning edge constitute.
The ring flange of contact pin parts of the present utility model 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.
Contact pin parts of the present utility model 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 is subjected to external force when pulling, motive force by 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 central optical fiber can be drawn badly, also make the contact pin parts easier for installation by aramid fiber.
Description of drawings
Fig. 1 is the structural representation of the contact pin parts of optical connector of the present utility model.
Embodiment
As shown in Figure 1, the contact pin parts comprise contact pin 1, contact pin 1 is plugged in the front end oral area of ring flange 2, the rear end of ring flange 2 is connected with back cover 4, be provided with a plurality of ring grooves on the outer ring of ring flange 2 vertically side by side, spiral-lock O-ring seals 3 in each ring groove, the outside surface of back cover 4 afterbodys has the conical surface that external diameter diminishes gradually, coincide on this conical surface and be set with the tapered sleeve 7 that inner ring is a conical surface closing in structure, activity is equipped with nut 5 on tapered sleeve 7 outer rings, the front inner wall of nut 5 is provided with internal thread, and conical surface the place ahead of back cover 4 is provided with the external thread cylinder with the screw-internal thread fit of nut 5.The faying face of nut 5 inner rings and tapered sleeve 7 outer rings is provided with axial occlusion structure, this axial occlusion structure be by turn edge on the nut inner ring that fastens 9 and tapered sleeve 7 outer rings on outer turning edge 10 constitute.In use, aramid fiber 6 between optical cable 5 crusts and the optical fiber is installed between the conical surface outside surface and tapered sleeve 7 inner rings of back cover 4 afterbodys, and nut 5 is screwed on the back cover 4, when screwing nut 5, nut 5 can promote the male cone (strobilus masculinus) compression fit of inner conical surface with the back cover 4 of tapered sleeve 7, thereby aramid fiber 6, tapered sleeve 7, back cover 4 are fixed as one.When optical cable 8 was subjected to the external force pulling, motive force was applied on tapered sleeve 7, the back cover 4 by aramid fiber 6, and can not affect central optical fiber; When the ring flange 3 of pulling contact pin parts or back cover 4, can affect whole optical cable 8 to move, and needn't worry central optical fiber can be drawn badly, make the contact pin parts easier for installation by aramid fiber.
