Above-mentioned disclosed waterproof optical fiber connector patented product, by attachment unit interface Optimal Structure Designing, reaches the object strengthening connector sealing; But this connector construction relative complex, complicated structure can cause the stability of connector Fiber connection and intracellular signaling.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of outdoor water-proof joints of optical fibre, adopt the connector loose mail of high-quality, be equipped with the waterproof cable of high-quality and corrosion resistant high-quality water repellent component, be applied to and connect key lightguide cable link and photoreceiver, solve the problem that joints of optical fibre waterproof effect under current outdoor rugged surroundings is poor.
The technical solution of the utility model is as follows:
A kind of outdoor water-proof joints of optical fibre, hold optical cable and B to hold optical cable to form by connector nipple, inner diameter seal circle, connected with outer casing, end-face seal ring, connector coupling, A.Connector nipple one end is that pyramidal structure holds optical cable to be connected with A, and the other end is insert being connected jointing holes of joint and connector coupling, and center section is external thread column structure.Connector coupling one end is that pyramidal structure holds optical cable to be connected with B, and the other end is external thread column structure, and cylindrical center is to jointing holes, and connector coupling centre position is limited step.Connected with outer casing is cylindrical shell structure, and two terminal circle bore dia is different, and small sircle hole one end has fixing step, and connected with outer casing inwall is perfect thread structure.
The external thread column structure of connector nipple designs annular groove near pyramidal structure one side end face, for installing inner diameter seal circle.The limited step thread cylinder structure side design annular groove toward the outside of connector coupling, for installing end-face seal ring.A, B hold optical cable to be and to have water-proof function fiber optic cables, and are connected with the pyramidal structure of connector nipple and connector coupling respectively, and to guarantee between optical cable with connector reliable is connected and waterproof.A holds optical cable to stretch into connector nipple, and arranges conventional fiber butt junction in the insertion joint of connector nipple; Meanwhile, B hold optical cable stretch into connector coupling, and in connector coupling to arranging fiber alignment seat in jointing holes.When the insertion joint of connector nipple stretch into connector coupling to jointing holes after, A holds the fiber alignment head of optical cable to realize hold with B the connection of the fiber alignment seat of optical cable, thus realizes the connection of A, B end optical fiber.
Connection after connected with outer casing docks with connector coupling for connector nipple, the female thread structure of connected with outer casing is connected by helicitic texture with the external thread column structure of the inside and outside joint of connector.Before connected with outer casing is installed, in connector nipple annular groove, inner diameter seal circle is installed, in the annular groove at connector coupling limited step place, end-face seal ring is installed, connected with outer casing screws in from connector nipple tip, through connector coupling until inner diameter seal circle and connector nipple annular groove compress by the fixing step of connected with outer casing, the annular groove of end-face seal ring and connector coupling compresses by the front end face of connected with outer casing simultaneously.The front and back end of connected with outer casing realizes the water-tight of the whole joints of optical fibre by different O-ring seals.
For improving waterproof effect and the serviceable life of joints of optical fibre entirety, the inside and outside joint of connector and connected with outer casing carry out anti-oxidation process, and meanwhile, inner diameter seal circle and end-face seal ring select corrosion-resistant, oxidation resistant elastomeric material to be made.
Effect of the present invention and benefit are these outdoor water-proof joints of optical fibre, annular groove is set at connector inside and outside joint O-ring seal is installed, connected with outer casing, while the inside and outside joint of fixed connector, realizes the waterproof sealing to the whole joints of optical fibre by compression two ends O-ring seal; Connector is reasonable in design, and structure is simple, and easy to operate, reliability is high, can be widely used in outdoor various complexity, rugged surroundings.
