Description

Cable protective sleeve

Technical Field

The utility model relates to a cable protection sleeve.

Background

In practical application, in order to protect the cable from being damaged and broken, a metal cable protective sleeve with certain mechanical strength is sleeved outside the cable. The cable protective sleeve is particularly arranged in a section where a communication cable and a power line are crossed, so that the short circuit accident caused by the disconnection of the power line is prevented, the communication cable and the steel wire rope are electrified, the cable, a switch and a machine core plate are protected, the whole machine is not burnt out, and a certain isolation effect is realized on the magnetic field interference of the power line. The cable protection sleeve is mostly made of metal materials, wherein the galvanized steel pipe is generally adopted due to good corrosion resistance. The end face edge of the cable protection sleeve made of metal materials is sharp and sharp, even barbs and the like can be formed in the cutting process, so that the surface of the cable can be easily cut and damaged in the process of penetrating the cable.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a cable protection sleeve.

In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a cable protection sleeve, is including the steel pipe that is used for wearing to establish the cable, the at least one end of steel pipe is equipped with tip cable protection device, and this tip cable protection device include with the fixed joint sleeve of steel pipe tip to and rotate set up in the exit portion of joint sleeve supplies the plastics sheath that the cable that stretches out the steel pipe passed.

In some embodiments, the inner circumference of the joint sleeve is provided with an internal thread which is matched, connected and fixed with an external thread arranged on the outer circumference of the end part of the steel pipe.

In some embodiments, the joint is sleeved on the end of the steel pipe and fixed with the steel pipe through a plurality of locking screws of radial through nails.

In certain embodiments, the plastic jacket has an inner ring diameter that is less than an inner ring diameter of the steel tube.

In some embodiments, the plastic sheath is inserted into the nipple outlet portion and is a tight fit with the nipple.

In some embodiments, the outer end of the plastic sheath is formed with a ring of limiting flange abutting against the end face of the joint sleeve for preventing the plastic sheath from falling into the steel pipe under external force.

In some embodiments, the inner edge of the outer end of the plastic sheath is provided with a rounded chamfer for contact with the cable.

In some embodiments, a grounding post is disposed on the splice enclosure.

The scope of the present invention is not limited to the technical solutions formed by specific combinations of the above technical features, and other technical solutions formed by arbitrary combinations of the above technical features or equivalent features should be covered. For example, the above features and the technical features (but not limited to) having similar functions disclosed in the present application are mutually replaced to form the technical solution.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the utility model discloses owing to set up tip cable protection device at the steel pipe tip for the outer material of cable can not be direct and sharp steel pipe port contact at the tip position of steel pipe, avoids being cut the damage, thereby has effectively protected the cable, has prolonged cable life.

Drawings

The invention will be further described with reference to the following drawings and examples:

fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic structural diagram of another embodiment of the present invention.

Wherein: 1. a cable; 2. a plastic sheath; 2a, a limiting flange; r, chamfering an arc; 3. a joint sleeve; 4. a steel pipe; 5. And locking the screw.

Detailed Description

Example 1: as shown in fig. 1, it is a specific implementation of this kind of cable protection sleeve that the utility model provides, it is the same with conventional technology, has the steel pipe 4 that is used for wearing to establish cable 1, and the utility model discloses an improvement point lies in, is equipped with tip cable protection device in the wherein one end of this steel pipe, and this tip cable protection device comprises with steel pipe end fixing's joint cover 3 and the plastics sheath 2 that supply in this joint cover 3 to stretch out the cable 1 of steel pipe 4 and pass jointly, the rotation centerline of plastics sheath 2 with the central line of joint cover 3 coincides mutually, in the wiring construction, cable 1 can rotate with plastics sheath 2 together, avoids rubbing. And the diameter of the inner ring of the plastic sheath 2 is smaller than that of the inner ring of the steel pipe, so that the surface of the cable 1 is prevented from being contacted with the end surface of the steel pipe 4.

In this embodiment, the inner periphery of the joint sleeve 3 is provided with internal threads, and the internal threads are matched, connected and fixed with external threads arranged on the outer periphery of the end part of the steel pipe 4. And the plastic sheath 2 is inserted into the joint sleeve 3 and is tightly matched with the joint sleeve 3.

In this embodiment, a circle of limiting flange 2a abutting against the end surface of the joint sleeve 3 is formed on the outer periphery of the outer end of the plastic sheath 2, so as to prevent the plastic sheath 2 from falling into the steel pipe 4 due to external force.

In addition, in the embodiment, the inner edge of the outer end of the plastic sheath 2 is provided with an arc chamfer R to contact with the cable 1. The cable can be prevented from contacting with the sharp corner of the inner edge of the outer end of the plastic sheath when being bent, and the protection function of the cable is further improved.

The connector sleeve is provided with a grounding column for a customer to externally connect a grounding wire, so that current possibly generated by the cable is grounded.

Example 2: as shown in fig. 2, the present invention provides another fixing manner for the cable protecting sleeve, and the present embodiment is different from embodiment 1 in that the joint sleeve 3 is fixed to the steel pipe 4 by two locking screws 5 penetrating radially.

The above-mentioned embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, which should not limit the scope of the present invention. All modifications made according to the spirit of the main technical scheme of the present invention shall be covered within the protection scope of the present invention.
