Detailed description of the invention
The crimping mode that existing LC2.0,1.6,12 optic cable diameter union joint uses in crimping mode is by crimp rings, Kev bracing wire to be crimped on the locating snap ring of LC after-frame set, and cable sheath this be to be blown at the hot blast of blowing hot wind by pyrocondensation HUANGBAI(sic) heat-shrink tube on crimp rings to be fixed under heat-shrink tube under contracting.Entirely being undertaken by Kev bracing wire in terms of bearing pulling force, so existing defects in terms of stretching resistance, and crust is to be fixed by heat-shrink tube pyrocondensation, and fixing at the aging rear crust of heat-shrink tube is not the most firm easily to come off, and workman exists certain danger on operation blowing hot wind.LC integral type crimp head 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, see Fig. 1 and Fig. 2, integral type of the present utility model crimping LC union joint, including dust cap 1, lock pin 2, spring 3, front frame set 4, little Bai pipe 5, after-frame set 6, tail sleeve 7, crimp rings 8, Kev bracing wire 9, little nail 10, crust 11, optical cable 12 and optical fiber 13.Lock pin 2 includes lock pin 2 body and is positioned at the caudal peduncle of lock pin 2 body end, and lock pin 2 is placed in front frame set 4, and little Bai pipe 5 and spring 3 are sheathed on caudal peduncle；Front frame set 4 and after-frame set 6 are connected and form a cavity, lock pin 2, spring 3 and little Bai pipe 5 are fixed in this cavity；Kev bracing wire 9 is crimped on after-frame set 6 by one end of crimp rings 8, and Kev bracing wire 9 and crust 11 are crimped on riveting parts by the other end of crimp rings 8, are cased with tail sleeve 7 outside crimp rings 8；There is perforate the centre of riveting parts, so that optical cable 12 passes through；Lock pin 2 is fixed in optical fiber 13 one end, and the other end stretches out cavity and stretches out, and optical cable 12 is sheathed on optical fiber 13 outside stretching out cavity.
Dust cap 1 is worn on lock pin 2, plays dustproof effect.Lock pin 2 is made up of ceramic insertion core and caudal peduncle.Spring 3 is enclosed within the caudal peduncle of lock pin 2, plays buffering and reset response.Lock pin 2 overlaps in former frame set 4.Little Bai pipe 5 is enclosed within the caudal peduncle of lock pin 2, matches with optical cable 12, then is fixed by a technique such as glue, solidification, prevents optical cable 12 from coming off.After-frame set 6 is made up of the aluminum component part of anterior plastic portions and rear portion, and after-frame set 6 is connected with the screens on front frame set 4 by the stuck point on after-frame set 6 with front frame set 4, lock pin 2, spring 3 and little Bai pipe 5 is fixed in the cavity of union joint.Tail sleeve 7 is enclosed within crimp rings 8.
Seeing Fig. 3 and Fig. 4, Kev bracing wire 9 is crimped on after-frame and overlaps on 6 latter half of aluminum components by the fore-end of crimp rings 8, be union joint be primarily subjected to falling part.Kev bracing wire 9 is the pulling force bearing piece of optical patchcord.Kev bracing wire 9 and crust 11 are crimped on little nail 10 by the latter half of crimp rings 8, the most both can fix optical cable 12, crust 11, and can share again a part of pulling force, make the stretching resistance ability of optical cable 12 be greatly promoted.Central axis direction along little nail 10 offers through hole, and optical cable 12 can be made to pass through, and makes optical cable 12 not be destroyed when crimping.Crust 11 is wrapped in the outside of optical cable 12, for protecting the optical fiber 13 within optical cable 12.The model of optical cable 12 is not intended to, such as 0.9 optical cable.
This utility model have changed crimp rings, sees Fig. 5 and Fig. 6, and crimp rings 8 uses the column structure of hollow to realize.Basis is the most novel has given up conventional HUANGBAI(sic) heat-shrink tube, saves HUANGBAI(sic) heat-shrink tube pyrocondensation this procedure in crimp rings, it also avoid employee and operates the danger that blowing hot wind exists.
This utility model uses little nail 10, sees Fig. 7 and Fig. 8 (and Fig. 3 and Fig. 4), and the longitudinal section of little nail 10 is T-shaped, and the center axial position of little nail offers through hole.Crust 11 is enclosed within little nail 10, with crimp rings 8 afterbody, optical cable 12 crust 11 is crimped on little nail 10, it is to avoid optical cable 12 crust 11 caused because HUANGBAI(sic) heat-shrink tube is aging comes off；Meanwhile, the via on little nail 10 can well protect optical cable be not forced into or damage by pressure when crimping.
Seeing Fig. 9 and Figure 10, tail sleeve 7 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 V-groove mouth.By the rear portion grooved bore of tail sleeve is carried out reasonable layout, it is allowed to bending resistance higher so that this whole tail end is difficult to be broken off, GR326 can be crossed.
This novel LC integral type crimp head improves existing structure, has given up conventional HUANGBAI(sic) heat-shrink tube, saves HUANGBAI(sic) heat-shrink tube pyrocondensation this procedure in crimp rings 8, it also avoid employee and operates the danger that blowing hot wind exists.Seeing Fig. 3, its crimping mode is Kev bracing wire 9 to be crimped on the locating snap ring 61 of LC union joint after-frame set 6, and crust 11 is then to be enclosed within little nail 10 to be crimped on little nail 10 by crimp rings 8 afterbody, thus will not damage 0.9 optical cable 12 within optical cable 12 by pressure；And crust 11 is firmly crimped on little nail 10 and can share a part of pulling force.
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.
