Description

Technical Field

[0001] The utility model relates to the technical field of cable structures, in particular to a cable structure which can prevent internal wire cores from being compressed and dislocated. Background Art

[0002] The traditional cable structure consists of an internal conductor and an insulation layer, and is protected by a sheath on the outside. However, when used for a long time or subjected to external forces, the internal core may be dislocated or damaged due to pressure. The basic structure of the traditional cable consists of four parts: the core conductor, the insulation layer, the shielding layer, and the protective layer. The existing methods for preventing the internal core from being dislocated due to pressure have many disadvantages. For example, there are many gaps on the inside of the existing cable structure, which can easily cause the internal core to move from its original position. Secondly, when the pressure on the cable is too high, the overall shape of the internal core can easily change. Therefore, the above technical problems need to be solved. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example: See Figure 1-5A cable structure for preventing internal cores from being compressed and dislocated in the utility model comprises a protective sleeve 1, an inner sleeve 2 is arranged on the inner side of the protective sleeve 1, a plurality of tightly connected arc strips are arranged between the inner sleeve 2 and the protective sleeve 1, and a gap is arranged between the arc strips on both sides, and a buffer sleeve 3 is arranged on the inner side of the inner sleeve 2, a plurality of raised strips are equidistantly arranged on the outer side of the buffer sleeve 3, flame retardant powder is filled between the two raised strips, and an insulating sleeve 4 is tightly attached to the inner side of the buffer sleeve 3, and a cable anti-dislocation structure is installed on the inner side of the insulating sleeve 4, and the flame retardant powder installed between the raised strips can effectively prevent the spontaneous combustion of the cable during use.

[0020] In the utility model, the cable anti-misalignment structure includes an insulating dividing layer 5 and a main cable protective shielding sleeve 7, one side of the insulating dividing layer 5 is tightly attached to the inner wall of the insulating sleeve 4, and the other side is fixed to the outer wall of the main cable protective shielding sleeve 7, and insulating shielding sleeves are installed between the insulating dividing layers 5. The insulating dividing layer 5 installed on the outer wall of the main cable protective shielding sleeve 7 is convenient to increase the contact area between the main cable protective shielding sleeve 7 and the filler 10, which can effectively prevent the inner core from being misaligned; a conductor 6 is installed between the insulating dividing layer 5 and the main cable protective shielding sleeve 7, and the outer side of the conductor 6 is covered with an insulating shield. The insulating shield covered on the outer side of the conductor 6 can effectively prevent the conductor 6 from being in close contact with the filler 10, resulting in poor contact.

[0021] In the utility model, outer protective strips 8 of the main cable are evenly distributed on the inner wall of the main cable protection shielding sleeve 7. The outer protective strips 8 are annularly fitted on the outer wall of the main cable sleeve. The outer protective strips 8 on the inner wall of the main cable protection shielding sleeve 7 can prevent the main structure of the wire core from changing when under pressure, causing damage to the wire core structure; a steel wire rope 9 is installed in the middle of the inner side of the main cable protection shielding sleeve 7. The steel wire rope 9 in the middle of the inner side of the cable can effectively improve the tensile strength of the cable and prevent the cable from being disconnected during use; fillers 10 are installed between the various structures on the inner side of the insulating sleeve 4. The fillers 10 inside the cable can effectively improve the stability and pressure resistance of the wire core and reduce the risk of dislocation.

[0022] Working principle: When the utility model is used, firstly, the outer side of the main wire core protection sleeve 1 is wrapped with an outer protective strip 8, and then a steel wire rope 9 is installed on the inner side of the outer protective strip 8 to enhance the tensile strength of the cable, and then the main cable protection shielding sleeve 7 on the outside of the outer protective strip 8 is used to further protect the wire core, and then the insulating dividing layer 5 on the outside of the main cable protection shielding sleeve 7 is used to increase the contact area with the filler 10, and then the insulating shielding between the main cable protection shielding sleeve 7 and the insulating dividing layer 5 is wrapped on the outside of the conductor 6 to separate the conductor 6 from the filler 10; secondly, the internal cable main structure is insulated and protected from the outside through the insulating sleeve 4, and then the buffer sleeve 3 on the outside of the insulating sleeve 4 is used to play a buffering role after the wire core is subjected to pressure, and then the cable is protected when under pressure through the gap between the arc structure between the inner sleeve 2 on the outside of the buffer sleeve 3 and the protective sleeve 1.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
