Description
Technical field
the present invention relates to a kind of optical connector, relate in particular to a kind of covered wire cable connector.
Background technology
covered wire cable is selected as main leading in cable structure by each big operator, and its market consumption increases substantially just year by year, and is corresponding, and the use of the joints of optical fibre made from covered wire cable is also increasing substantially.
normally used joints of optical fibre, the optical cable of use are conventional single fiber cables, and its design feature is: be loose structure between tight tube fiber, non-metal reinforcement member and the sheath, and tight tube fiber about 5mm length of can in cable, freely stretching.When making wire jumper, need tight tube fiber and contact pin body be fixed into an integral body, non-metal reinforcement member and connector link together.It is then different to make the joints of optical fibre with covered wire cable, by the covered wire cable that coated fiber, reinforcement and sheath are formed, between coated fiber, reinforcement and the sheath, is closely to be bundled together, and can not produce any position and move.Adopt and to purchase the common connector loose mail that obtains on the market and assemble just unrealisticly, need design a kind of new construction again, to the connector loose mail of rubber-insulated wire cable.
Summary of the invention
the present invention seeks to: a kind of covered wire cable connector is provided, to realize the continued access to optical cable with less parts, improves its speed that continues.
technical scheme of the present invention is: a kind of covered wire cable connector; Comprise outer body, interior body and contact pin body; Said outer body is socketed on the interior body; In the contact pin body is located in the central through hole of body and front end stretch out in outside the outer body, said connector also comprises covered wire cable, is set in the backstop sleeve pipe on the covered wire cable; Be arranged between backstop sleeve pipe rear end and the covered wire cable, be used to tighten the rubber-insulated wire holding firmware of covered wire cable; And be set on contact pin body and the backstop sleeve pipe front end, be used to be connected the neck bush of contact pin body and backstop sleeve pipe, said covered wire cable front portion forms the bare fibre section of front end and is positioned at the coated fiber section at bare fibre section rear portion after peeling off, and said bare fibre section all is plugged in the ceramic insertion core of contact pin body; Said coated fiber section front end is plugged in to be fixed interior also splicing of metal caudal peduncle of contact pin body, also is provided with between said contact pin body and the backstop sleeve pipe and extends axially spring.
Concrete mounting structure between
said spring and contact pin body, the backstop sleeve pipe is: said contact pin body middle part is provided with a circle flange; Spring housing is located at contact pin body rear portion; Spring one end supports and is located at the flange rear end face, and the other end supports in the annular positioning groove that is located at week in the backstop sleeve pipe front end.
Concrete mounting structure between
said neck bush and contact pin body, the backstop sleeve pipe is: the annular slot of the rear end of said neck bush and backstop sleeve pipe front end periphery connects and fixes; The front end of neck bush has a circle inner shield ring, and this inner shield ring pushes against on the front end face of flange.
The concrete structure of
said rubber-insulated wire holding firmware is: said rubber-insulated wire holding firmware has two pins at least; And the distance between adjacent two pins is less than the bond length of covered wire cable; The rear end tube wall of said backstop sleeve pipe is provided with the jack that supplies pin to insert, and the pin of said rubber-insulated wire holding firmware passes in the sheath that jack is plugged in covered wire cable.
are further, two groups of pins before and after said rubber-insulated wire holding firmware has, and every group of pin be two, and the distance between two pins in every group is all less than the bond length of covered wire cable.
For better fixedly covered wire cable, the rear portion endoporus of said backstop sleeve pipe is the butterfly hole that cooperates with the covered wire cable profile
.Said covered wire cable is provided with the tail cover in the rear sleeve of backstop sleeve pipe.
Number of assembling steps of the present invention is:
Step 1: fiber stripping work is carried out in the front portion to covered wire cable, so that anterior one section bare fibre section and the one section coated fiber section of forming of covered wire cable;
Step 2: insert the contact pin body of having annotated glue after above-mentioned bare fibre section and coated fiber section passed tail cover, backstop sleeve pipe and spring, again that glue curing is good;
step 3: spring, backstop sleeve pipe are pushed away to contact pin body direction successively; Up to drawing close; Be inserted in contact pin body and spring backward with neck bush more in the past; This moment, the inner shield ring of neck bush pushed against on the front end face of flange, and neck bush is continued to connect and fix up to the rear end of neck bush and the annular slot of backstop sleeve pipe front end periphery to pusher.Because under the situation at this moment; The optical fiber of the inside will be in case of bending; This moment need be with covered wire cable pulled backwards gently, up to the optical fiber of the inside state linearly, and then the rubber-insulated wire holding firmware is inserted in the sheath and backstop sleeve pipe of covered wire cable side; Make backstop sleeve pipe, covered wire cable and rubber-insulated wire holding firmware card be integral integral body, thereby make the stationkeeping of realization covered wire cable;
step 4: push to the tail cover, the outer body of packing into, accomplish the assembling of connector.
Advantage of the present invention is:
1. the present invention is simple and reasonable, is easy to disassembly and assembly under special circumstances, and volume is little, and is in light weight, low cost of manufacture, and building block quantity is few, and assembling makes the operating process of optical fiber connection simply quick easily.
are the method for the coated fiber section of the present invention through in the backstop sleeve pipe, keeping certain-length 2.; Reduced because the flexible fiber bending radius that causes of contact pin body; Thereby reduced because the loss that optical fiber causes too greatly because of bending radius, finally reached the purpose of less insertion loss.
3. the present invention adopt four pins of rubber-insulated wire holding firmware to block covered wire cable and backstop sleeve pipe simultaneously, thereby realize fixing between adapter connector and the optical cable, and are simple in structure, fixing reliable.
4. in the assembling process, case of bending can appear in the bare fibre in the backstop sleeve pipe, and the present invention can be after adjusting to linear state with bare fibre, realizes fixing to covered wire cable through the rubber-insulated wire holding firmware again.
