Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Fig. 1 a～b, it is a kind of structural representation of fiber cable branch device.
This fiber cable branch device comprises housing 11 as shown in Figure 1a and cap 12 as shown in Figure 1 b.Housing 11 can be realized and removably connecting with cap 12, wherein a kind of connected mode can be that housing 11 is connected by screw with cap 12, concrete, as shown in Fig. 1 a～b, multiple screw holes position 111 can be set on housing 11, the double-screw bolt 121 of multiple projections is set on cap 12, and screw hole position 111 is corresponding one by one with double-screw bolt 121.In the time connecting, by double-screw bolt 121 contrapositions on the screw hole position of housing 11 111 and cap 12, be then fixed with screw.Certainly, the connected mode of housing 11 and cap 12 has multiple, these are only example.
Housing 11 can form airtight cavity after being connected with cap 12, thereby can play the effect of water proof and dust proof.Concrete, the edge that can contact with cap 12 on housing 11 arranges adhesive tape or sealing strip, same, the edge contacting with housing 11 on cap 12 also arranges adhesive tape or sealing strip, thereby in the time that housing 11 is connected with cap 12, due to the elastic reaction of adhesive tape or sealing strip, form airtight cavity.
The another kind of mode that forms airtight cavity, as shown in Figure 2, this fiber cable branch device can also comprise water proof and dust proof packing ring 21, this water proof and dust proof packing ring 21 can be separated from each other with housing 11 and cap 12, in the time that housing 11 is connected with cap 12, water proof and dust proof packing ring 21 is between housing 11 and cap 12.If housing 11 is connected by screw with cap 12, on water proof and dust proof packing ring 21, be also correspondingly provided with screw hole position 211, screw is by the screw hole position 111 on housing 11, the screw hole position 211 on water proof and dust proof packing ring 21, and after double-screw bolt 121 on cap 12, tighten fixing.
On this housing 11, be also provided with at least three for the position, hole 112 of optical cable is installed, optical cable, is then exported through other positions, hole 112 in the interior branch that realizes of housing 11 by position, hole 112.The quantity of this position, hole 112 can arrange as required.
In the present embodiment, fiber cable branch device comprises easy housing and cap, and make housing cap can realize airtight connection, thereby the absolute construction of both having realized miniaturization fiber cable branch device, makes again fiber cable branch device have high functions of waterproof and dustproof, can apply to severe outdoor environment.
In another embodiment, this fiber cable branch device can also comprise optical cable fixed part, and this optical cable fixed part is for crimping by the optical cable of position, hole, and optical cable fixed part can hang upside down at position, hole place after crimping optical cable, to ensure the pulling force of optical cable.
As Fig. 3 a～3b is depicted as a kind of optical cable fixed part.This optical cable fixed part comprises interior crimp rings 31 and outer crimp rings 32.Outer crimp rings 32 can be sleeved on the outside of interior crimp rings 31.
As shown in Figure 4, in the time that optical cable 41 is installed, first the position, a certain hole 112 of optical cable 41 being passed on housing 11, then optical cable 41 is passed to interior crimp rings 31, optical cable 41, through after interior crimp rings 31, is peeled off the crust of optical cable 41, and the aramid fiber exposing is turned up to the outside of interior crimp rings 31, and then outer crimp rings 32 is sleeved on to the outside of interior crimp rings 31, the aramid fiber that crimping is turned up.In optical cable fixed part after crimping is good, the xsect of outer crimp rings 32 is pressed into for example polygon (preferably polygon more than hexagon), for example this polygonal circumscribed circle diameter can be greater than the diameter of position, hole 112, in the time that optical cable 41 good crimping is drawn outside housing 11, inside and outside crimp rings just can be hung upside down on the circular hole wall of position, hole 112, thereby can ensure the pulling force requirement of optical cable, the pulling force of 300N can bear in the time of outdoor utility in the single branch of for example outdoor optical cable.
In order to strengthen the water proof and dust proof effect of fiber cable branch device, can also between optical cable and housing, seal by seal.For example, as shown in Figure 5, above-mentioned optical cable 41 is installed after, can be in housing 11 inside increase seal 51 in the close place of optical cable 41 and housing, for example heat-shrinkable T bush is sleeved on to the outside of the inside and outside crimp rings of optical cable 41, thereby reaches waterproof/dustproof effect.Between housing 11 outsides are by optical cable 41 and housing 11, adopt the seals such as glue 52, optical cable 41 and housing 11 are sealed fixing.
Secondly, in housing, be also provided with as shown in Figure 1 for coiling fine groove 113, after optical cable and device tail optical fiber fuse; to remain bare fibre coils according to groove 113; put into corresponding installation position 114, make optical fiber impaired to prevent optical fiber free-extension, thus protection optical fiber.
The structure that is more than fiber cable branch device is described, in the time using this fiber cable branch device, can be first by optical cable according to mode as shown in Figure 4 by optical cable by inside and outside crimp rings, then as shown in Figure 5, optical cable sealing is fixed on housing with heat-shrinkable T bush and colloid.After optical cable in housing and device tail optical fiber fuse, will remain bare fibre good according to ditch slotted disk, finally water proof and dust proof packing ring and cap will be placed on housing successively, screw down fixing, as shown in Figure 6.
The disclosed fiber cable branch device of the utility model has high functions of waterproof and dustproof, can apply to severe outdoor environment, and water proof and dust proof can reach IP67; Can meet by inner and outer rings crimping is fixing the requirement that the single branch of outdoor cable pulling force when the outdoor utility must bear 300N; The critical piece of this device can adopt anti-UV plastic casing, and stable mechanical performance can meet outdoor-40-70(DEG C) requirement; This device belongs to the outdoor cable branch unit of miniaturization of vast capacity, at least can hold 1 and enter 2 and go out and above multiple dilatation, and maintenance is more convenient than general encapsulation box, can change simply branched line, and device is positive without being connected and fixed a little, outward appearance grace.
Certainly, be more than preferred implementation of the present utility model.It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model ultimate principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
