Detailed description of the invention
When LC union joint of the prior art and LC adapter are installed on cabinet panel, a certain distance must be retained between LC union joint and LC adapter and following LC union joint and LC adapter above, facilitate finger can put in by LC union joint by handle, hidden discount is unclamped, LC union joint could be extracted.From the foregoing, it will be observed that the installation operation inconvenience of LC union joint and LC adapter, strong influence working performance in prior art.LC high density simply connected union joint of the present utility model is precisely in order to solve the problems referred to above and propose.In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Concrete, as a specific embodiment, seeing Fig. 1-Fig. 9, LC high density simply connected union joint of the present utility model includes dust cap 1, lock pin 2, front frame set 3, spring 5, little Bai pipe 6, after-frame set 7, pull bar 8, tail sleeve 9, optical fiber 10, optical cable 11, Kev bracing wire 12, crust 13, crimp rings 14, little nail 15.
Wherein, seeing Fig. 1-Fig. 4, lock pin 2 includes ceramic insertion core and is positioned at the caudal peduncle of ceramic insertion core end, and lock pin 2 is placed in front frame set 3, and little Bai pipe 6 and spring 5 are sheathed on the caudal peduncle of lock pin 2；Front frame set 3 and after-frame set 7 are connected and form a cavity, lock pin 2, spring 5 and little Bai pipe 6 are fixed in this cavity；Kev bracing wire 12 is crimped on after-frame set 7 by one end of crimp rings 14, and Kev bracing wire 12 and crust 13 are crimped on riveting parts 15 by the other end of crimp rings 14, are cased with tail sleeve 9 outside crimp rings 14；There is perforate the centre of riveting parts 15, so that optical cable 11 passes through；Lock pin 2 is fixed in optical fiber one end, and the other end stretches out cavity and stretches out, and optical cable 11 is sheathed on the outer fiber stretching out cavity.Dust cap 1 is sheathed on the end of lock pin 2, for dust-proof.The longitudinal section of little nail 15 is T-shaped, and offers through hole along the central axis direction of little nail 15, so that optical cable 11 passes through, and protects optical fiber not to be subject to crushing with optical cable.Crimp rings 14 uses the column structure of hollow to realize.Tail sleeve 9 includes the column structure of hollow, and the end of this column structure is to contract and extends formation one frustum cone structure, and the outer surface of frustum cone structure is provided with multiple notch, and rational notch is distributed, and enhances bending resistance.Preferably, notch is V-type notch design so that this whole tail end is difficult to be broken off.
Seeing Fig. 5-Fig. 9, pull bar 8 includes that shaft-like body 81 and the handle portion 82 and the fixed part 83(that lay respectively at body two ends are shown in Fig. 9)；Have by handle on front frame set 3, see Fig. 8 by being provided with barb 4(), the fixed part of pull bar 8 insert before frame set 3 make to contact with pull bar 8 by upper barb 4, before pulling the handle portion of pull bar 8 then frame overlap 3 by being pulled down into.Simultaneously, for steady brace 8, after-frame set 7 is provided with T-shaped fixture 71(and sees Fig. 6 and Fig. 7), corresponding, the slotted eye coordinated with T-shaped fixture 71 is offered on the fixed part of pull bar 8, make pull bar 8 be fixed on after-frame set 7 in T-shaped fixture 71 is placed in this slotted eye, and the T-shaped fixture 71 on after-frame set 7 can limit up and down, the torsion of pull bar 8.It addition, in order to prevent pull bar 8 layback too much, the fixed part of pull bar 8 is additionally provided with block, cooperatively forms limit effect with the T-shaped fixture 71 of after-frame set 7, prevent pull bar 8 layback too much.Seeing Fig. 9, in the present embodiment, the handle portion of pull bar 8 is hexagonal structure, facilitates user hand-held, is difficult to skid, and good looking appearance.
When specifically installing, as it is shown in figure 5, front frame set 3 is connected with pull bar 8 by upper barb 4, the T-shaped fixture on after-frame set 7 and the connection of pull bar 8.Having slotted eye on pull bar 8 makes it can pull after after-frame set 7 is gone forward.During use, pull that front frame can put by pull bar by leaving behind, so that union joint unclamps with the hidden discount on adapter.The T-shaped fixture that after-frame puts can ensure that pull bar can only pull after union joint is gone forward and can not up and down, left and right, twist motion.Block on pull bar is positive stop, limits the layback of pull bar, thus ensures that pull bar will not frame overlaps before leading portion departs from barb.
In sum, this utility model adds Tiebar structure on LC union joint, only need to pull pull bar, easily LC union joint can be extracted with LC adapter, save cabinet panel space, reduce equipment cost, and it is quick to be easy to use, and has good practicality.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
