Abstract
The utility model relates to a line ear technical field, more specifically relates to waterproof line ear of cable, including the connecting plate, wherein, the connecting plate is connected with the line cover, and line cover one end is connected with the bulge, is equipped with the transition piece between bulge and the line cover, and the transition piece inclines to set up on vertical side, and the transition piece is 45 degrees to 60 degrees with the contained angle of vertical direction. The utility model discloses can effectively promote the waterproof performance of cable terminal, moisture content when preventing to rain is along in the terminal infiltration cable of lug.
Description
Technical field
The utility model is related to line ear technical field, more particularly, to cable waterproof line ear.
Background technology
After the completion of the ordinary lines ear crimping that midium voltage cable outdoor termination uses at present, line ear end and cable main insulating layer
There are certain gap, the measure of water-proofing treatment is to be used as by winding water blocking tape between online ear and cable conductor at water proof
Reason, then sealed using pyrocondensation or shrinkage insulating sheath as outer layer.These measures issue existing certain from operating condition for many years
Hidden danger, is mainly manifested in that the insulating sheath operation time limit is long or silicon occurred by heat ageing and split, and line ear portions are exposed, the water when rainy
Part penetrates into the litzendraht wire in-core of main push-towing rope conductor along the gap between line ear end and cable main insulating layer, due to electrical outdoor cable end
Setting height(from bottom) be typically no less than 4.5 meters or more, with become mounted on cable distribution box or case in other side cable terminal deposit
In the difference in height not less than 3 meters, when the moisture content accumulation in cable core to a certain extent, and from end line ear and main insulating layer
Between gap exudation, end is caused to discharge, end, distribution box or babinet is caused to be exploded and destroyed.In addition, the length of ordinary lines ear
The requirement that midium voltage cable head connecting screw adstante febre carries out livewire work bypass drainage processing using line ear end cannot be met.
Utility model content
The utility model is at least one defect overcome described in the above-mentioned prior art, provides cable waterproof line ear, effectively
The water resistance of cable terminal is promoted, moisture content is penetrated into along line ear end in cable when preventing from raining.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Cable waterproof line ear, includes connection
Plate, wherein, connecting plate connects wired set, and line covers one end and is connected with protrusion, and transition piece, transition are equipped between protrusion and line set
Part is obliquely installed in the vertical direction, and the angle of transition piece and vertical direction is 45 degree to 60 degree.
The utility model provides cable waterproof line ear, and connecting plate one end connects wired set, is realized and cable by line set
Connection.Online set one end is connected with protrusion, and protrusion is covered compared with line to be protruded, and realizes the package to cable.Protrusion is to line
Package effect is played in set one end, effectively can prevent moisture from passing through.The installation of line ear for convenience simultaneously, in protrusion and line set
Between be equipped with transition piece.The angle of transition piece and vertical direction is 45 degree to 60 degree, and the transition piece being obliquely installed can facilitate line
The installation of ear.Transition piece can improve the magnetic distribution of cable simultaneously, while can be utilized in cable connection position adstante febre
Line ear end carries out livewire work bypass drainage processing.
In one embodiment, protrusion is set to hollow cylinder, and the length of the protrusion is 25mm to 35mm.
It can play the role of waterproof during the online ear use of protrusion, in order to play good waterproof action,
The length of protrusion is set to 25mm to 35mm, on the premise of the installation of line ear is not influenced, realizes good waterproof action.
In one embodiment, line ear connecting plate is equipped with bolt hole.
Preferably, line set and minimum range on protrusion vertical direction are 6mm to 10mm.
Preferably, protrusion interior diameter value is more than more than cable major insulation diameter value 2mm.
In order to ensure the good water proofing property of line ear and be easily installed, protrusion interior diameter value is more than cable major insulation diameter value
The distance of more than 2mm, at least 2mm can ensure not influence the installation of line ear on the premise of line ear waterproof is realized.
Compared with prior art, the online pressure contact portion position that covers forms a vertical water-proof umbrella cover to the utility model, will effectively carry
The water resistance of outdoor cable terminals is pressed in liter, moisture is along between line ear end and cable main insulating layer when preventing from raining
The litzendraht wire in-core of main push-towing rope conductor is penetrated into gap.Protrusion disclosure satisfy that the charged of midium voltage cable head connecting screw adstante febre simultaneously
Operation bypass drainage processing requirement.
Description of the drawings
Fig. 1 is the utility model overall structure diagram in one embodiment.
Specific embodiment
Attached drawing is only for illustration, it is impossible to be interpreted as the limitation to the utility model；In order to more preferably illustrate this implementation
Example, some components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；For those skilled in the art

Exemplary illustration, it is impossible to be interpreted as the limitation to the utility model.
Embodiment 1：
As shown in Figure 1, the utility model provides cable waterproof line ear, include connecting plate 1, connecting plate 1 connects wired set
2, online 2 one end that cover are equipped with protrusion 5.
As shown in Figure 1, in the present embodiment, connecting plate 1 is equipped with bolt hole 3.It was equipped between protrusion 5 and line set 2
Part 4 is crossed, the set-up mode of transition piece 4 is is obliquely installed compared with vertical direction, and inclined angle is 45 degree to 60 degree, transition piece
4 are set to chamfering structure.
As shown in Figure 1, in the present embodiment, protrusion 5 is set to hollow cylinder, and hollow cylinder is used for nested cable, realization pair
Cable is fixedly connected.The length of protrusion 5 is set to 30mm, and the protrusion 5 of 30mm length can be further ensured that line ear is realized
Stable waterproof action.
As shown in Figure 1,5 diameter value of protrusion is more than more than cable major insulation diameter value 2mm, in the present embodiment, protrusion 5
Diameter value is set to bigger 2mm than cable major insulation diameter value, and the diameter value of 2mm can be installed for cable provides sufficient space, together
When can avoid since gap is excessive water resistance being caused to decline.
As shown in Figure 1, in the present embodiment, since transition piece 4 compared with the inclined angle of vertical direction is 45 degree to 60 degree,
In order to enable transition piece 4 possesses appropriate length, line set 2 is set as 8mm with the distance on 5 vertical direction of protrusion.
