Above-mentioned technical proposal is connect, is equipped with O-ring seal in transition waterproof end cover.
Above-mentioned technical proposal is connect, internal stent includes bottom plate and side plate, and the side of bottom plate is arranged in side plate, and side plate is divided into two
A part, centre are equipped with notch；The both ends of bottom plate are equipped with card slot, and the cable sleeve for protruding into sleeve inner is placed in the card slot.
Above-mentioned technical proposal is connect, tabletting is additionally provided on side plate, tabletting is placed in the top of card slot, and tabletting is equipped with screw hole, tightly
Determine screw to be fixed in the screw hole.
Above-mentioned technical proposal is connect, side plate is reinforcing rib.
Above-mentioned technical proposal is connect, internal stent is integrated support.
The beneficial effect that the utility model generates is: the utility model protects connection section by connecting cylinder.It connects in cylinder
Area fiber is in line state.It plugs into box compared to tradition, the utility model patent has that small in size, watertightness is good, crushing resistance
Ability is high, pull resistance ability is strong, structure is simple, splice locations loss is low.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the external structure schematic diagram of the utility model embodiment cable connection cylinder；
Fig. 2 is the schematic diagram of internal structure of the utility model embodiment cable connection cylinder；

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
As shown in Figure 1, 2, the cable connection cylinder of the utility model includes sleeve 1, cable sleeve 5, waterproof connector 4, transition
Waterproof end cover 3, pre-tightens improved mat 6 at internal stent 2.
1 both ends of sleeve connect transition waterproof end cover 3；Cable sleeve 5 is set on optical cable to be connected, and is connect by waterproof
First 4 connect with transition waterproof end cover 3；It pre-tightens improved mat 6 to be placed on the cable sleeve 5 for protruding into sleeve inner, and passes through tightening
Screw 7 is fixed；The optical cable at sleeve both ends is accessed in the same way in sleeve and welding, the optical cable after interior welding are placed in inside
On bracket 2.
The utility model is to splicing cables with indoor flexible optical cable.Stainless steel cable waterproof can be selected in the waterproof connector of cable
Connector group is matched according to cable sleeve size and is used, and as optical cable adapter and guarantees the watertightness of cable sleeve.
Transition waterproof end cover 3 is matched with O-ring seal, for bridging sleeve 1 and Waterproof connector of cable, matching thread
Glue has used sealing, fixed function.
It pre-tightens Anti-skid sheet 6 and directly contacts cable sleeve 5, by screwing holding screw 7 to 5 applied force of cable sleeve, squeeze
Cable sleeve 5 causes a small amount of deformation, to reach locking optical cable.
Internal stent 2 can control optical cable to enter the length of sleeve, so that optical fiber is in line the state of not stressing, and adjustable
The position of heat-shrink tube 8 keeps it placed in the middle.Optical fiber can avoid bending loss caused by the fault of disk fibre in direct-connected state.Internal stent 2 is main
Play protection heat-shrink tube and guarantees that the fibre loss connected in cylinder meets the requirements.As shown in figure 3, internal stent 2 can be whole
Body formula bracket, easy to form and intensity are high.The internal stent 2 includes bottom plate 21 and side plate 22, and bottom plate 21 is arranged in side plate 22
