Description
Technical field
The utility model relates to a kind of optical cable, specifically refers to a kind of syndeton for optical cable rapid abutting joint.
Background technology
Fiber cable joint is to realize docking and the company's parallel operation produced between optical cable with cable line box.It is a kind of joint being used for fixing optical cable, realizes the effect can accurately docked between optical cable with cable line box, is applicable to docking between all optical cables with cable line box.
In use, although it is found that the cable line pod interface used at present has advantage, but still there is many defects.One by one docking to be installed for optical fiber installation personnel, need fibre-optical bending, stretching during docking, can not carry out the same time docking or dismantling, dismounting can only be docked one by one.In addition, because interface internal is a hollow tube-shape, after causing docking, when wrapping optical fiber, haul optical fiber a little, optical fiber interface will loosen and leave, and does not directly come off, but can cause installing situation appearance not in place, there is the hidden danger do not connected.For industry spot, need highly reliable optical cable interface, and this optical cable interface can not get loose under the drawing of bearing certain force.
Utility model content
The purpose of this utility model is to provide a kind of syndeton for optical cable rapid abutting joint, facilitates the rapid abutting joint of optical cable and cable line box, and ensures the tightness of in use optical cable connection, avoids optical cable loosen or come off.
The purpose of this utility model is achieved through the following technical solutions:
A kind of syndeton for optical cable rapid abutting joint, comprise the joint body be set on optical cable, external diameter is provided with along its axis to the installed surface successively decreased in the direction in close axle center at the contact jaw of described joint body, hingedly on described installed surface be provided with the ringwise multiple and compact heap of array distribution, compact heap outer wall has bottom surface along its axis to the ring groove tilted near joint body axis direction, slide in ring groove and be provided with the tight loop adapted with it, compact heap inwall one end contacts with installed surface, the compact heap inwall other end is formed slopely seal face along its axis to the direction away from joint body axle center, also comprising the cross section be arranged on compact heap contact jaw end face is the rubber ring of U-shaped, and described installed surface is arranged with the ring-shaped rubber projection matched with it, and described ring-shaped rubber projection is just to described seal face.During utility model works, the core peeled off is docked with line pod interface, the contact jaw of joint body is close towards line pod interface simultaneously, when contact end face and the interface end contact of joint body, the axis of tight loop along optical cable is moved to the direction near line pod interface, one end of compact heap is then moved until the wall contacts of dip plane bottom compact heap and line pod interface around its pin joint run-off the straight, make core while being connected with line pod interface inside, compact heap is by the outer wall of fastening for joint body online pod interface, when avoiding in use optical cable outlet to swing, joint body and line pod interface occur to loosen or depart from, ensure stability when optical cable uses, wherein, tight loop is set in ringwise multiple and on the compact heap of array distribution, make when tight loop is moved, the same end of multiple compact heap is shunk to the axle center of line pod interface simultaneously and is pressed down, ensure that connector is tightly fitted on online pod interface outer wall, compared with prior art, avoiding slides to arrange on nut and online pod interface outer wall on cable offers the external thread with nut screw connection, eliminate the continuous rotating nut of artificial needs rotate and carry out the fastening or operation of unclamping to line pod interface, improve the installation effectiveness of optical cable.Wherein, when the contact end face of joint body and the end face of line pod interface come in contact collision, cross section is that the rubber ring generation deformation of U-shaped is with buffering gouging abrasion between the two, after there is deformation, rubber ring can also play sealing function to line pod interface simultaneously, avoids the impurity such as extraneous dust to enter the serviceability affecting optical cable interface end points in line pod interface, and under the long-time using state of compact heap, it is insufficient that hinged place bottom it there will be lubrication, namely compact heap cannot freely swing on installed surface, tight loop cannot be moved on compact heap, the utility model is arranged with ring-shaped rubber projection at installed surface near the contact end face side of joint body, make while joint body and line pod interface close contact by compression set, outwards being ejected by compact heap when loosening can appear in its deformation recovery acting force produced between compact heap and line pod interface, namely resistance when tight loop moves when core and interface depart from is reduced, improve the flexible performance of use of joint body.
The angle of inclination of described ring groove bottom surface is identical with the angular dimension that the compact heap inwall other end tilts.The bottom of ring groove and the other end of compact heap are all obliquely installed, and the contrary angle of inclination size simultaneously of vergence direction is identical, when making tight loop move certain displacement, namely the distance of the decentralization of fastening block keeps synchronous with the decentralization distance of compact heap all the time, make the contact area that the outer wall of the dip plane of compact heap inwall and line pod interface keeps enough, the situation reducing this dip plane and line pod interface outer wall point cantact occurs, and prevents from occurring between joint body and line pod interface outer wall to loosen.
The angle of inclination of described ring groove bottom surface is 15 ~ 40 °.As preferably, the angle of inclination of ring groove bottom surface is arranged within the scope of 15 ~ 40 °, while ensureing that tight loop keeps enough clamping dynamics to multiple compact heap, the convenient movement fast when joint body and line pod interface depart from, to realize the quick disengaging of compact heap inwall and line pod interface, increase the dirigibility of joint body.
Described tight loop is the ring bodies that an elastic caoutchouc rod thermoplastic is bending and shaping.As preferably, described tight loop is set to the ring bodies that two ends do not occur to connect, and by the brake forming of elastic caoutchouc rod thermoplastic, to the line pod interface outer wall contact stress be applied on himself, there is certain surge capability when tight loop is moved in ring groove, and then reduce impaired possibility.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model avoids to slide to arrange on nut and online pod interface outer wall on cable and offers the external thread with nut screw connection, eliminate the continuous rotating nut of artificial needs rotate and carry out the fastening or operation of unclamping to line pod interface, improve the installation effectiveness of optical cable;
2, the utility model is when tight loop moves certain displacement, namely the distance of the decentralization of fastening block keeps synchronous with the decentralization distance of compact heap all the time, make the contact area that the outer wall of the dip plane of compact heap inwall and line pod interface keeps enough, the situation reducing this dip plane and line pod interface outer wall point cantact occurs, and prevents from occurring between joint body and line pod interface outer wall to loosen;
3, the angle of inclination of ring groove bottom surface is arranged within the scope of 15 ~ 40 ° by the utility model, while ensureing that tight loop keeps enough clamping dynamics to multiple compact heap, the convenient movement fast when joint body and line pod interface depart from, to realize the quick disengaging of compact heap inwall and line pod interface, increase the dirigibility of joint body.
