Abstract

The utility model discloses an insulating sheath, which consists of a sheath body, wherein the sheath body is integrally hollow and tubular, one end of the sheath body is arranged in a frustum shape, and the inside of the frustum-shaped sheath body is provided with step-shaped structures with diameters sequentially decreasing from outside to inside, and the insulating sheath has the advantages that: not only is beneficial to covering the naked conductor in the conductor shield, but also is beneficial to being suitable for different shapes of the ends of the wires.

Description

Insulating sheath

Technical Field

The utility model relates to the technical field of sheaths, in particular to the technical field of an insulating sheath for electric power.

Background

The insulating sheath for the power equipment is made of silicon rubber materials through high-temperature compression molding, has excellent electrical performance, is aging-resistant and high-low temperature-resistant, and can be used under any conditions. The insulating safety protection article is an insulating safety protection article which must be matched with the terminal of power equipment such as a transformer, a lightning arrester, an outdoor switch and the like, and can effectively prevent power failure accidents caused by artificial contact, electricity stealing, small animal or sundry lapping, wet flashing salt mist, chemical gas corrosion and the like of the terminal of the power equipment exposed outside, thereby avoiding huge economic loss brought by the power failure accidents. Therefore, the insulating sheath is a safety protection product commonly used for electric equipment. However, the existing insulating sheath has the following defects: firstly, the existing insulating sheaths are all customized sheath shapes for certain parts and can only be suitable for the use of the designated power parts; secondly, when the cable is used for the lead with different wire diameters, the operator needs to select the insulating sheaths with different wire diameters for matching, and the use is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects and provide the insulating sheath which has a simple structure, is very convenient to use, can be suitable for leads with different wire diameters and can be suitable for lead ends with different shapes.

The technical solution adopted by the present invention to solve the above technical problems is as follows:

the utility model provides an insulating sheath, comprises the sheath body, the whole hollow tubulose that is of sheath body, the one end setting of this sheath body is the frustum form, sets up the step form that is the diameter outside-in and reduces in proper order in the internal portion of the sheath of this frustum form.

The step face that each step form was described in this patent is cylindrical.

This patent the axis of each cylindrical step face coincides mutually with the axis of the sheath body.

This patent the corresponding department in outer end with the step form is provided with the fracture on the sheath body lateral surface.

This patent the corresponding department with the step form on the sheath body lateral surface is provided with the line footpath sign.

The utility model adopts the technical proposal to achieve the following beneficial effects:

1. the sheath body is integrally arranged in a hollow tubular shape, so that the exposed conductor can be covered in the sheath body, and the sheath body is suitable for different shapes of the ends of the conductors;

2. the frustum-shaped sheath body is internally provided with the step-shaped sheath body with the diameter sequentially reduced from outside to inside, so that the requirement of being suitable for conductors with different wire diameters is facilitated, and the conductors with different wire diameters can be perfectly covered in the sheath body.

3. Through setting up the fracture, do benefit to the quick convenient intercepting of constructor and need just the sheath body of unnecessary part down.

4. Through setting up the line footpath sign, do benefit to constructor and conveniently find the intercepting position more, can effectively improve the efficiency of construction.

5. The sheath can effectively avoid short-circuit accidents caused by mistaken overlapping of small animals or foreign matters such as birds and beasts and the like with wires; can effectively prevent electrical accidents caused by condensation flashover, pollution flashover and ice column sticking snow; the corrosion of acid rain, salt mist and harmful chemical gas to the end of the wire is effectively prevented; effectively avoiding the personal casualty accident caused by the pedestrian mistakenly touching the exposed electrical contact.

Detailed Description

As shown in fig. 1, 2, 3 and 4, an insulating sheath is composed of a sheath body 1, the sheath body 1 is hollow and tubular, one end of the sheath body 1 is provided with a frustum-shaped 2, the inside of the sheath body 1 of the frustum-shaped 2 is provided with step-shaped 3 with diameters decreasing from outside to inside, a step surface 4 formed by each step-shaped 3 is cylindrical, thereby being beneficial to realizing good contact with the outer surface of a lead 5, not only achieving the purpose of preventing loosening, but also having a certain sealing effect, preventing pollutants such as acid rain and salt mist and the like from entering the sheath body 1 from the position, the central axis of each step-shaped cylindrical surface 4 is coincided with the central axis of the sheath body 1, a fracture 6 is arranged on the outer side surface of the sheath body 1 corresponding to the outer end of the step-shaped 3, and being beneficial for constructors to intercept the unused and redundant sheath body 1 from the fracture 6 quickly and conveniently, the corresponding department with step form 3 is provided with line footpath sign 7 on the lateral surface of the sheath body 1, is favorable to constructor to know the quick selection intercepting position.
