Description
Technical field
The utility model relates to a kind of tight sleeve optic cable joints of optical fibre.Belong to technical field of optical fiber communication.
Background technology
Along with Fibre Optical Communication Technology constantly develops, the optical fiber cable of supporting application presents variation, and using external diameter except that routine is the indoor single fiber cable of 2mm and 3mm, a kind of butterfly leading in cable that Fiber to the home uses occurred.Conventional indoor single fiber cable is loose nested structure, and promptly optical fiber and oversheath right and wrong are close-connected, and optical fiber can be movable in sheath; And the butterfly leading in cable is a tight tube structure; Be that optical fiber closely is connected with oversheath, very close to each other between optical fiber and oversheath, stiff in sheath.Prior art has three types to the joints of optical fibre of this tight sleeve optic cable: the first kind is to make with the connector loose mail with conventional indoor single fiber cable; Oversheath is fixed; These joints of optical fibre in use; Internal optical fiber occurs with the axial rollback of contact pin, produce crooked even fracture in that connector is inner, cause the loss of light signal even open circuit; Second type is lengthening connector internal cavities, enough curved spaces is arranged after making internal optical fiber with the axial rollback of contact pin, is unlikely bending and fractures, but still have the crooked problem that causes loss of optical signal; The 3rd type is that oversheath closely is connected through special metal caudal peduncle with contact pin, and when the axial rollback of contact pin, tight sleeve optic cable is also retreated thereupon; Internal optical fiber can not produce bending; Avoided the loss of optical signal that causes because of fibre-optical bending even open circuit, but such connector is when optical cable is drawn, contact pin is retreated thereupon; The contact pin end face that links to each other with the opposite end produces the gap, causes loss of optical signal.Simultaneously, in these three types of connector procedures, it is high all to exist cable outer sheath to open the stripping dimension precision requirement, and the section of having diameter is the optical fiber of 0.25mm between contact pin and oversheath, exposes the problem that fractures easily.
Summary of the invention
What the utility model proposed is a kind of tight sleeve optic cable joints of optical fibre; Its purpose is intended to overcome the above-mentioned defective of existing in prior technology; Be applicable to tight sleeve optic cables such as butterfly leading in cable; Can make oversheath and the ceramic insertion core and the synchronous axially-movable of caudal peduncle of tight sleeve optic cable, and, make the connection of optical fiber more reliable and more stable the effectively restriction of axially-movable distance; Eliminate the fiber segment that exposes the 0.25mm diameter between contact pin and oversheath simultaneously, make joints of optical fibre manufacture craft simpler.
The technical solution of the utility model: it is characterized in that comprising ceramic contact pin, contact pin caudal peduncle, interior cover, shell, tailstock, spring, fixture and tight sleeve optic cable; Wherein ceramic contact pin, contact pin caudal peduncle, interior cover, shell, tailstock, spring are equipped with central through hole; The front end through hole of contact pin caudal peduncle is connected fixing with the rear end of ceramic contact pin; The optical fiber of tight sleeve optic cable runs through the central through hole of ceramic contact pin, and the rear end through hole that the oversheath of tight sleeve optic cable penetrates the contact pin caudal peduncle is connected with ceramic contact pin and contact pin caudal peduncle; The front end of contact pin caudal peduncle is provided with ring-shaped step, and the inwall of interior cover is provided with ring-shaped step, and spring housing is on the contact pin caudal peduncle; In the central through hole that overlaps in the contact pin caudal peduncle is through; Spring is arranged between contact pin caudal peduncle ring-shaped step and the interior cover inwall ring-shaped step, and the front end socket of cover rear end face and tailstock was fixed in stretched out the rear end of contact pin caudal peduncle, and fixture is located at the tailstock rear portion; Fixture locking cable outer sheath, the cover outside in shell is socketed in.
The advantage of the utility model: the optical fiber of tight sleeve optic cable and oversheath are connected with ceramic contact pin and contact pin caudal peduncle, and when the axial rollback of contact pin, tight sleeve optic cable is also retreated thereupon, and internal optical fiber can not produce bending, has avoided the loss of optical signal that causes because of fibre-optical bending; In the inwall of cover be provided with contact pin stopping step, when having avoided being drawn because of optical cable, contact pin is excessively retreated thereupon, the contact pin end face generation gap that links to each other with the opposite end causes loss of optical signal.Simultaneously, do not expose the fiber segment of 0.25mm diameter between contact pin and oversheath, simplified joints of optical fibre manufacture craft.
Description of drawings
Accompanying drawing 1 is the perspective exploded view of the tight sleeve optic cable joints of optical fibre.
Accompanying drawing 2 is cross-sectional view of Fig. 1.
Accompanying drawing 3 is interior cover inwall synoptic diagram of the tight sleeve optic cable joints of optical fibre.
