Abstract
A kind of shrinkage cable outdoor terminal, include the wire connection terminal of cable, the protecting pipe on package cable top and cable upper end, insulating self-adhesive band is wound on gap between the protecting pipe upper end and wire connection terminal, seal pipe is installed outside the insulating self-adhesive band, it is characterised in that：One end of the seal pipe is in contact with the end face of protecting pipe, and the other end of seal pipe is in contact with the casing on the wire connection terminal, and insulative water-proof adhesive tape is wound on the contact surface of the contact surface of the seal pipe and protecting pipe, seal pipe and casing.The utility model all covers in all gaps that may be present between cold-shrinkable terminal and wire connection terminal, and is also handled in the gap at triplicity well with insulative water-proof adhesive tape, has accomplished comprehensive waterproofing protection.
Description
Technical field
The utility model belongs to field of electrical equipment, and in particular to a kind of shrinkage cable outdoor terminal.
Background technology
Outdoor cable sometimes can generate pollution flashover and electricity after using terminal installation due to the reason of wet weather
Phenomena such as climbing, it is very dangerous, and the reason for causing this phenomenon be dirt in the case of humidity, soluble substance is gradually molten
Yu Shui forms one layer of conductive film in insulating surface, substantially reduces the dielectric level of insulator, occur under electric power field action
Strong electric discharge phenomena.Existing shrinkage cable outdoor terminal, is generally provided with rain skirt, with it is simple in structure, using more pacifying
The advantages of complete.But may be because the joint gap of cold-shrinkable terminal and wire connection terminal and cause pollution flashover, therefore still have presence
The phenomenon that pollution flashover and electricity are climbed.
Chinese patent Authorization Notice No. CN 205509463U, authorized announcement date are public in August, 2016 utility model of 24 days
A kind of shrinkage cable outdoor terminal is opened, for sewage to be avoided to enter caused by the joint gap of cold-shrinkable terminal and wire connection terminal
Pollution flashover, it is characterised in that：It is wound on gap between the shrinkage outdoor terminal protecting pipe upper end and the wire connection terminal absolutely
Originate from adhesive tape, seal pipe is installed outside the insulating self-adhesive band.
The device prevents water from entering by the cooperation of insulating self-adhesive band, seal pipe and silicone band, effectively prevent pollution flashover and
Electricity climbs the generation of phenomenon.But seal pipe is overlapped on shrinkage outdoor terminal protecting pipe in the device, due to seal pipe with
Shrinkage outdoor terminal protecting pipe is two kinds of materials, and shrinkage ratio is different, is probably led in use because of external environment
The occurrence of contact position is caused risk occur, causes infiltration, and the other end of seal pipe is to reach waterproof by silicone band
Purpose, but under severe external environment, how long the service life of silicone band remains to be discussed if having, waterproof effect causes anxiety.
The content of the invention
The purpose of the utility model is to overcome problems of the prior art, provide a kind of simple in structure, waterproof effect
Good shrinkage cable outdoor terminal.
In order to achieve the above object, the technical solution of the utility model is：A kind of shrinkage cable outdoor terminal, including electricity
The wire connection terminal of cable, the protecting pipe on package cable top and cable upper end, between the protecting pipe upper end and wire connection terminal
Insulating self-adhesive band is wound on gap, seal pipe is installed outside the insulating self-adhesive band, it is characterised in that：The seal pipe
One end is in contact with the end face of protecting pipe, and the other end of seal pipe is in contact with the casing on wire connection terminal, described close
Insulative water-proof adhesive tape is wound on the contact surface of the contact surface of tube sealing and protecting pipe, seal pipe and casing.
The notch for being provided centrally with passing through for wire connection terminal of described sleeve pipe, between the inner wall and wire connection terminal of the notch
It is provided with insulative water-proof glue.
Nano-sized hydrophobic layer is both provided on the outer wall of the protecting pipe, seal pipe and casing.
The utility model compared with prior art, has the following advantages：
1st, the utility model combining closely by protecting pipe, seal pipe and casing, will be between cold-shrinkable terminal and wire connection terminal
All gaps that may be present all cover, and are also handled in the gap at triplicity well with insulative water-proof adhesive tape, accomplish
Comprehensive waterproofing protection effectively avoids pollution flashover and electricity from climbing the generation of phenomenon, and cable use is safer.
2nd, the utility model is in the centrally disposed notch passed through for wire connection terminal of casing, and the inner wall in notch and wiring
Insulative water-proof glue between terminal is set, so can effectively prevent moisture from being penetrated at notch, improve waterproof effect.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the axial view of the utility model.
In figure：Cable 1, protecting pipe 2, wire connection terminal 3, insulating self-adhesive band 4, seal pipe 5, casing 6, insulative water-proof adhesive tape 7,
Notch 8, insulative water-proof glue 9.
Specific embodiment
The utility model is described in further detail below in conjunction with description of the drawings and specific embodiment：
Referring to Fig. 1-Fig. 2, a kind of shrinkage cable outdoor terminal, including cable 1, package cable 1 top protecting pipe 2 and
The wire connection terminal 3 of 1 upper end of cable is wound with insulating self-adhesive band 4 on the gap between 2 upper end of protecting pipe and wire connection terminal 3,
Seal pipe 5 is installed, one end of the seal pipe 5 is in contact with the end face of protecting pipe 2, sealing outside the insulating self-adhesive band 4
The other end of pipe 5 is in contact with the casing 6 on wire connection terminal 3, and described sleeve pipe 6 is provided centrally with for wire connection terminal 3
The notch 8 passed through is provided with insulative water-proof glue 9, the seal pipe 5 and sheath between the inner wall of the notch 8 and wire connection terminal 3
The contact surface of pipe 2, seal pipe 5 on the contact surface of casing 6 with being wound with insulative water-proof adhesive tape 7.
Nano-sized hydrophobic layer is both provided on the outer wall of the protecting pipe 2, seal pipe 5 and casing 6, it is hydrophobic due to hydrophobic layer
Effect, causes water droplet to be not bound to 6 surface of protecting pipe 2, seal pipe 5 and casing, so on the one hand prevents the shape of conductive moisture film
Into the appearance for having prevented pollution flashover situation, on the other hand, water droplet can melt away the dirt on its surface, reach and clean its surface
Effect.
