Embodiment
Hereinafter will describe the utility model with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Embodiment 1
Referring to Fig. 1, present embodiment provides a kind of cable sealing device, comprises water joint 200, line ball nut 300 and insulating sealer 100, and wherein, the structure of water joint 200, line ball nut 300 is identical with structure of the prior art, no longer describes in detail here.Insulating sealer 100 is used to be enclosed within the cable between water joint 200 and the line ball nut 300, and insulating sealer 100 comprises:
Wherein, the overall diameter of ring portion 103 is greater than the internal diameter of the through wires hole of line ball nut 300, to guarantee that ring portion 103 under the effect of screwing force, is unlikely to be extruded into line ball nut 300 outsides by the through wires hole of line ball nut 300.
Wherein, tube portion 102 can be cylinder, referring to Fig. 2.Its manufacturing process is: an outsidepiston is peelled off crust according to actual needs, and peel off crust end plastic packaging at cable.Cable 101 plastic packagings of peelling off behind the crust become two faces of cylinder, and wherein, the little face of cylinder i.e. tube portion 102 is that cable seals and seal face, and the big face of cylinder is a ring portion 103, rocks in sealing place for preventing cable; The crust 104 that also comprises cable among Fig. 2; Behind the cable knob plastic packaging, can effectively prevent because of the cable appearance scratch the back water along lead in inflow equipment, cause the problem of device damage.
In order to strengthen compactness, can after being enclosed within cable, ring portion 103 between ring portion 103 and cable, coat some glue, in order to preventing that in the use, cable rocks in sealing place, and then prevent to infiltrate problems such as outdoor equipment owing to rock the water that brings.
Preferably, the hardness of tube portion 102 is greater than the desired threshold value of screwing force between opposing water joint 200 and the line ball nut 300.In the time of can solving on-the-spot the installation so effectively, the problem that screwing force is restive.
The overall diameter of tube portion 102 is less than the internal diameter of the through wires hole of water joint 200, so that tube portion 102 is inserted in the through wires hole of water joint 200, reaches the purpose of protection cable inner core.
Preferably, the length of tube portion 102 is greater than the length of the sealing shroud in the water joint 200, less than the length of the screw rod of water joint 200.
The material of the insulating sealer 200 of present embodiment can be plastics, also can have the insulating material of certain degree of hardness for other, for example vulcanie etc.
Cable sealing device in the correlation technique normally directly passes water joint with cable, tightens water joint line ball nut; Present embodiment is by installing insulating sealer 100 between water joint 200 and line ball nut 300.
Present embodiment is by installing insulating sealer 100 between water joint 200 and line ball nut 300, can solve cable sealing device existence scene effectively difficulty is installed, the problem that waterproof effect is difficult to ensure, and then made things convenient for workmen's operation, improved the fail safe of equipment.
Embodiment 2
Present embodiment provides a kind of cable sealing device, referring to Fig. 4, this device comprises line ball nut, water joint, ring portion 103 (being also referred to as spacing cylinder) and tube portion 303, wherein, tube portion 303 adopts is structure shown in Figure 3 among the embodiment 1, no longer describes in detail here.
The assembling process of sealing device is as follows: earlier cable is passed water joint, the line ball nut of hand-tight make-up water joint again, and push away cable and allow the end face on the big face of cylinder (being ring portion 103) withstand on the locking end face 302 of water joint screw rod, make that the big column on the cable is that ring portion 103 is in line ball nut through wires hole 301.Like this, when line ball nut check, what just can guarantee the sealing of cable and cable fixes, prevents that cable from rocking in water joint.The utility model is intended to carry out plastic packaging for the termination of cable, and cable and plastics are airtight behind the plastics, and during the radial compaction end, power is decomposed at plastic part, can not influence electrical index.
The utility model design is with the termination of the outdoor flexible cord cable of different-diameter, the cable of decorticating of reserving certain-length according to actual needs carries out plastic packaging, cable behind the plastic packaging will pass the line ball nut of water joint, and make the cable access device, solved sealing problem between cable and the equipment with lower cost.
As can be seen from the above description, the utility model has been realized following technique effect:
When 1) tightening the line ball nut, can not cause cable to damage;
2), improved the sealing property of device at the termination of cable plastic packaging one joint sealing insulator;
3) the plastic packaging structure of ledge structure can guarantee that cable do not swing in water joint, guarantee the junction sealing of cable;
4) when device interior produces negative pressure, stop water access arrangement in the cable, the fail safe that has improved equipment.
In sum, the cable sealing device that provides of the foregoing description has characteristics such as good airproof performance, cost is low, engineering is easy to assembly.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
