Abstract
The utility model relates to a cable branching supporter, which is of the shape of a frustum. An included angle beta between the peripheral surface and the axis of the frustum is 20 degrees to 22 degrees. Three circular-arc-shaped through grooves are axially and evenly distributed on the periphery of the frustum. Since contact surfaces between the supporter and a three-phase cable are circular-arch-shaped, the supporter can be tightly jointed to the cable and wraps the cable. Therefore, the largest contact area can be obtained, the cable is not easy to swing easily, the friction can be increased, axial sliding between the cable and a support is avoided, the stability is good, the cable branching supporter is safe and reliable to use, the possibility of falling does not exist and potential personal safety hazards are avoided.
Description
Technical field
The utility model belongs to power domain, relates to cable, especially a kind of cable branch-off eyelid retractor.
Background technology
In order to improve the efficiency of construction of cable joint, need be at the cable joint position with cable branch-off, and then carry out cable and connect.In the present cable joint work progress, the staff does not have special-purpose bifurcated supporting tool, needs to use supporter (as the short section of cable) that threephase cable is separated, and cable separately back supporter is stuck in the threephase cable.There is following defective in the method for supporting of this form: 1, supporter is for being overlapped in the threephase cable, poor stability, and external force might landing and there is potential safety hazard in the injury personnel a little; 2, the supporter size is difficult to unifiedly, and all cables of incompatibility, and supporter need be carried out repeatedly fixing and position adjustment influence efficiency of construction; 3, supporter has taken certain space, influences staff's operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of safety and stability reliable cable branch-off eyelid retractor.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of cable branch-off eyelid retractor, eyelid retractor are frustum type, and the angle β of the outer edge surface of frustum and axis is 20-22 °, at axial uniform three the circular arc grooves that are shaped on of frustum outer rim.
And, be shaped on the technology through hole at the frustum center.
Advantage of the present utility model and beneficial effect are:
1, the contact-making surface of this eyelid retractor and threephase cable is circular arc, therefore can fit tightly and wrap cable, so not only can obtain maximum contact area, make cable be difficult for waving, can also increase friction, prevent that cable and support from seeing the generation axial slip, has good stable, safe and reliable, there is not the possibility that comes off, to the no hidden danger of safety of the person.
2, this eyelid retractor is taper, the phase-splitting even angle, and the cable mean forced does not cause physical damnification fully to the cable copper shield, helps to promote construction quality, improves efficiency of construction.
3, this eyelid retractor takes up room lessly, and standard is attractive in appearance, makes easily, and is with low cost, is applicable to various threephase cables.
4, this eyelid retractor adopts elastomeric material to make, anti-skidding and good insulation preformance, and hardness is moderate simultaneously, has certain mechanical strength, possesses the ability of the 35kV three-core cable of supporting section 300 and 240 square millimeters.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of cable branch-off eyelid retractor is frustum type, and its material selection rubber is made.The angle β of the outer edge surface of frustum 2 and axis is 20-22 °, and at axial uniform three the circular arc grooves 1 that are shaped on of frustum outer rim, these three circular arc grooves also can have certain angle, also can not have.In order to save material, make technology through hole 3 at the frustum center.
The instantiation of this cable branch-off eyelid retractor:
Three alternate range averaging values are 10cm (between core distance), and the angle mean value that cable is got along with horizontal plane at branch is 22 degree.More than two groups of data all satisfy the requirement of cable construction bifurcated, conform with construction specification.
Claims (2)
1. cable branch-off eyelid retractor, it is characterized in that: eyelid retractor is a frustum type, the angle β of the outer edge surface of frustum and axis is 20-22 °, is shaped on three circular arc grooves in that the frustum outer rim is axially uniform.
2. cable branch-off eyelid retractor according to claim 1 is characterized in that: be shaped on the technology through hole at the frustum center.
