Abstract
The utility model discloses a safety protection structure of a cable core, which comprises a protective sleeve and a screwing nut; the protective sleeve comprises a hard U-shaped sleeve cap, a flexible reducing ring is arranged at the opening end of the U-shaped sleeve cap in a sealing mode, the outer diameter of the reducing ring is gradually increased from the position far away from the U-shaped sleeve cap to the position close to the U-shaped sleeve cap, and external threads are arranged on the outer side of the reducing ring; the screwing nut is in threaded connection with the reducing ring. The advantages are that: the utility model has simple structure, convenient installation and removal, and firm and non-falling protection; the utility model can be used for cables with different sectional areas by fastening and sealing in a screwing mode, and has wide application range; through the matching of the reducing ring and the screwing nut, the cable core can be well sealed, the dust and the water can be effectively prevented, and the short circuit phenomenon caused by water inflow is avoided; the U-shaped sleeve cap is made of hard insulating materials, so that various accidental collisions or extrusion can be effectively resisted, and the cable core is protected to the maximum extent.
Description
The technical field is as follows:
the utility model relates to a power system relay protection field especially relates to a safety protection structure of cable core.
Background art:
in power plants and substations, disconnection and connection work is often required in relay protection work, and the disconnected wires are often electrified or can cause the malfunction of important equipment, so that the insulated tape is required to be wrapped to prevent mistaken touch. However, at the parcel of insulating tape and the in-process of demolising, because of its self viscidity problem, need pull, lead to ground connection or short circuit because of the mistake bumps easily when pulling, cause the accident, also the condition that the people electrocuted easily appears, in addition, the not firm condition that can also appear the adhesive tape and drop of insulating tape parcel. The whole operation process is inconvenient, and great potential safety hazards exist.
The utility model has the following contents:
an object of the utility model is to provide a simple structure, convenient to use, safe and reliable's safety protection structure of cable core.
The utility model discloses by following technical scheme implement:
a safety protection structure of a cable core comprises a protective sleeve and a screwing nut; the protective sleeve comprises a hard U-shaped sleeve cap, a flexible reducing ring is arranged at the opening end of the U-shaped sleeve cap in a sealing mode, the outer diameter of the reducing ring is gradually increased from the position far away from the U-shaped sleeve cap to the position close to the U-shaped sleeve cap, and external threads are arranged on the outer side of the reducing ring; the screwing nut is in threaded connection with the reducing ring.
The utility model has the advantages that:
the utility model has simple structure, convenient installation and removal, firm and non-falling guarantee, and avoids the risk brought by tearing the insulating tape, and particularly effectively avoids the phenomenon that the insulating tape falls off due to pulling and friction in the work of replacing the cabinet body and the like which needs a large amount of wires for dismantling; the utility model can be used for cables with different sectional areas by fastening and sealing in a screwing mode, and has wide application range; through the matching of the reducing ring and the screwing nut, the cable core can be well sealed, the dust and the water can be effectively prevented, and the short circuit phenomenon caused by water inflow is avoided; the U-shaped sleeve cap is made of hard insulating materials, so that various accidental collisions or extrusion can be effectively resisted, and the cable core is protected to the maximum extent.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural diagram of the present embodiment;
in the figure: the cable comprises a protective sleeve 1, a U-shaped sleeve cap 1.1, a reducing ring 1.2, a screwing nut 2 and a cable 3.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1:
the safety protection structure of a cable core shown in fig. 1 comprises a protective sleeve 1 and a screwing nut 2; the protective sleeve 1 comprises a hard U-shaped sleeve cap 1.1, a flexible reducing ring 1.2 is arranged at the opening end of the U-shaped sleeve cap 1.1 in a sealing mode, the outer diameter of the reducing ring 1.2 is gradually increased from the position far away from the U-shaped sleeve cap 1.1 to the position close to the U-shaped sleeve cap 1.1, the inner diameter of the reducing ring 1.2 is kept unchanged, and an external thread is arranged on the outer side of the reducing ring 1.2; the screwing nut 2 is screwed with the reducing ring 1.2. In this embodiment, all the components are made of insulating materials.
The use process comprises the following steps:
firstly, sleeving a screwing nut 2 on a detached cable 3; then, the detached cable 3 is inserted into the U-shaped sleeve cap 1.1 through the reducing ring 1.2, and the cable core is ensured to be completely inserted into the U-shaped sleeve cap 1.1; finally, the inner diameter of the reducing ring 1.2 is gradually in close contact with the cable 3 by screwing and screwing the screw cap 2, so that a good sealing effect is achieved, the cable core in the U-shaped sleeve cap 1.1 can be effectively waterproof and dustproof, and the short circuit phenomenon caused by water inflow is avoided.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
