Abstract
The utility model belongs to the field of optical communication, and relates to a rubber-insulated cable connector, which is specifically used for the connection of an FTTH (fiber to the home) rubber-insulated optical cable and an optical branching device, especially the fabrication of a connector. The rubber-insulated cable connector comprises a ceramic core insert, an inner body, an outer body, a spring, a sleeve base, a tail helve, a riveting connecting piece and a tail sheath, wherein one end of the tail sheath is wrapped at the end of the rubber-insulated cable and the other end thereof wraps the entire riveting connecting piece and the tail end of the tail helve, the riveting connecting piece is connected with the rubber-insulated cable and the tail helve, the sleeve cover, the inner body and the outer body are sequentially wrapped outside the tail helve, the spring is arranged between the sleeve base and the inner body, the outer body is wrapped at the one end of the tail sheath at the same time, and the ceramic core insert is arranged inside the inner body and connected with the tail helve. The rubber-insulated cable connector provided by the utility model has the advantages of reasonable design, low cost, high engineering efficiency, fixed product function, reliable quality, and low and estimable late-stage maintenance cost.
Description
Technical field
The utility model relates to a kind of rubber-insulated wire connector, specifically is used for the register one's residence making of continuing of covered wire cable and optical branching device, particularly connector of FTTH, belongs to optical communication field.
Background technology
In the prior art, each big operator all uses the PON(EPON in FTTH advances) technology, and insert in the engineering at FTTH, the mechanical bend function of convention inside cable and tension function can not satisfy FTTH(Fiber to the home) demand of house wiring.Under the situation of the market demand, presented low bending radius, high-intensity covered wire cable, will Fiber to the home in FTTH(by widespread) Access Network in.Nowadays runing the commercial city is to lay covered wire cable in advance in advance, and the operational mode of covered wire cable primarily belongs to following four classes: the L type continues fast, adapter plug, cold connector continue fast, covered wire cable continues with tail optical fiber or the interior welding mode of 86 panels.Above-mentioned several mode, slave unit cost, construction cost and operating efficiency, have that data cost height, engineering efficient are slow, the product function is fixing, quality is not firm, later maintenance cost can not budget etc. problems.
Summary of the invention
The rubber-insulated wire connector that technical problem to be solved in the utility model provides that a kind of reasonable in design, cost are low, engineering efficient height, product function are fixed, quality is firm, later maintenance cost is low and can budget.
It is this rubber-insulated wire connector that the utility model solves the problems of the technologies described above the technical scheme that is adopted, its design feature is: by ceramic insertion core, interior body, outer body, spring, the cover headstock, caudal peduncle, the riveting web member, the tail sheath is formed, one end of described tail sheath is wrapped in the end of rubber-insulated wire, the other end wraps up the end of whole riveting web member and caudal peduncle, described riveting web member connects rubber-insulated wire and caudal peduncle, described caudal peduncle also is enclosed with the cover headstock outward successively, interior body, outer body, be provided with spring between described cover headstock and the interior body, described outer body is wrapped in an end of tail sheath simultaneously, links to each other in the body and with caudal peduncle in described ceramic insertion core is arranged on.
One end of riveting web member described in the utility model is provided with projection, and the groove that is provided with on described projection and the caudal peduncle mates mutually.
Caudal peduncle described in the utility model is the metal caudal peduncle.
The utility model is compared with prior art and had the following advantages and effect: the utility model structural design advantages of simple, cost are low, engineering efficient height, product function are fixed, quality is firm, later maintenance cost is low and can budget.Perhaps the high speed plug is low than cold connector for executive cost, except the covered wire cable construction cost, also need the specialized engineering personnel make expense (the partial operation instrument also is indispensable) with the cold joint mode.And utilization rubber-insulated wire tail optical fiber need only be wanted the construction cost of optical cable laying, and other relevant expense can not take place.Since in factory, produce and finish, at Insertion Loss, return loss, end face comprises pulling force, environmental experiment all will be higher than the cold joint quick plug.It is above even higher that the return loss of rubber-insulated wire fixed connector can reach 50dB, the locking tissue is greater than 40N, and tail end optical cable pulling force is greater than more than the 50N, and the cold joint product has only 4N, once the query of drawing Insertion Loss to increase even can not use, this all is that the cold joint product is incomparable to the user slightly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label declaration: ceramic insertion core 1, interior body 2, outer body 3, spring 4, cover headstock 5, metal caudal peduncle 6, riveting web member 7, tail sheath 8, rubber-insulated wire 9.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment is made up of ceramic insertion core 1, interior body 2, outer body 3, spring 4, cover headstock 5, metal caudal peduncle 6, riveting web member 7, tail sheath 8.
The end of rubber-insulated wire 9 is inserted through tail sheath 8, stick in the riveting web member 7, riveting web member 7 also is wrapped in the tail sheath 8, riveting web member 7 firmly connects rubber-insulated wire 9 and metal caudal peduncle 6, end at riveting web member 7 is provided with projection, and the groove that is provided with on this projection and the metal caudal peduncle 6 mates mutually.Cover headstock 5 is wrapped in the outside of metal caudal peduncle 6, in the body 2, is provided with spring 4 between cover headstock 5 and the interior body 2 in the part of cover headstock 5 is wrapped in.Interior body 2 is wrapped in the outer body 3, and the end of outer body 3 and interior body 2 is provided with the ceramic insertion core 1 that links to each other with metal caudal peduncle 6.
The utility model is finished owing to producing in factory, at Insertion Loss, and return loss, end face comprises pulling force, environmental experiment all will be higher than the cold joint quick plug.It is above even higher that rubber-insulated wire connector of the present utility model return loss can reach 50dB, the locking tissue is greater than 40N, and tail end optical cable pulling force is greater than more than the 50N, and the cold joint product has only 4N, once the query of drawing Insertion Loss to increase even can not use, this all is that the cold joint product is incomparable to the user slightly.
