Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a high-flexibility drag chain cable. Background Art

[0002] Cables are media used for signal or power transmission in people's daily lives. Highly flexible special cables that can move back and forth with the drag chain without being easily worn are called drag chain cables, which are also commonly called towing cables and tank chain cables.

[0003] In daily use of cables, people need to perform appropriate maintenance on the inside of the cables according to the actual use environment, or when cutting the cables to a certain length, they usually need to disassemble the cables first. However, traditional cables are currently integrated and difficult to disassemble. Summary of the invention

[0004] In order to overcome the defects of the above-mentioned traditional cables, the present invention proposes a highly flexible drag chain cable.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] Highly flexible drag chain cable, composed of a cable body and a connector part connecting the two axial sides of the cable body; the cable body includes an outer sheath structure, an outer shielding layer, an inner sheath, a filling layer, an inner shielding layer and a number of inner cores twisted together from the outside to the inside; each inner core is composed of an inner insulating layer and a copper core wrapped in the inner insulating layer. The two connector parts are connected to the two sides of the cable body. The two connector parts are connected to the two axial sides of the cable body. The outer sheath structure is a detachable structure, which is convenient for manual recycling.

[0007] The reinforcement structure is composed of a main sliding sleeve installed on the side of the adapter close to the cable body, a plug slidably installed on the main sliding sleeve, and a lower sliding sleeve adapted to the plug. That is, after the metal plug is slidably plugged into the left and right sheaths, the plug can be slid down and inserted into the lower sliding sleeve, so that the middle of the plug abuts against the protruding material on the side, thereby achieving connection and fixation.

[0008] The beneficial effects of the present invention are:

[0009] The present invention has a novel structure, which not only enables the two joint parts to be disassembled in a sliding manner, but also facilitates the subsequent disassembly of the cable outer sheath part. The overall operation is convenient, and is convenient for subsequent maintenance, recovery, cutting and other related work of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0016] like Figure 1 and Figure 2 As shown, the highly flexible drag chain cable is composed of a cable body and a joint part connecting the two axial sides of the cable body; the cable body includes an outer sheath structure, an outer shielding layer 1, an inner sheath 2, a filling layer 7, an inner shielding layer 8 and a plurality of inner cores twisted together from the outside to the inside; each inner core is composed of an inner insulating layer 9 and a copper core 10 wrapped in the inner insulating layer 9.

[0017] Specifically, the two connector parts of the present invention are respectively connected to the two sides of the cable body. The two connector parts are respectively connected to the two axial sides of the cable body. The outer sheath structure is a detachable structure, which is convenient for manual recovery.

[0018] like Figure 2 As shown, the outer sheath structure is composed of a left sheath 3 and a right sheath 4 which are mutually supported. The left sheath 3 and the right sheath 4 can be easily disassembled.

[0019] like Figure 2 As shown, both the left sheath 3 and the right sheath 4 are provided with an extension portion 5; the extension portion 5 of the left sheath 3 is connected to the right sheath 4 via a screw. The screw is detachable.

[0020] like Figure 1 and Figure 2As shown, the outer parts of the left sheath 3 and the right sheath 4 are uniformly provided with a plurality of protruding materials 6. The protruding materials 6 can play a wear-resistant effect and can prevent the left sheath 3 and the right sheath 4 from being damaged.

[0021] like Figure 2 As shown, there are three inner cores.

[0022] like Figure 1 and Figure 3 As shown, each connector part is composed of a transfer seat 11 connected to a metal plug 12; a reinforcement structure is also installed on each transfer seat 11. The reinforcement structure is used to facilitate the stable connection between the metal plug 12 and the cable body.

[0023] like Figure 3 As shown, each adapter seat 11 is provided with a guide side groove 11a on the inner side thereof for slidingly cooperating with the protruding material 6. The above is a conventional design of a sliding structure, which limits the sliding and facilitates the connection between the inner core and the metal plug 12.

[0024] like Figure 3 As shown, the reinforcement structure is composed of a main sliding sleeve 13 installed on the side of the adapter 11 close to the cable body, a plug 14 slidably installed on the main sliding sleeve 13, and a lower sliding sleeve 15 adapted to the plug 14. That is, after the metal plug 12 is slidably plugged with the left sheath 3 and the right sheath 4, the plug 14 can be slid down and inserted into the lower sliding sleeve 15, so that the middle of the plug 14 abuts against the protruding material 6 on the side, thereby achieving connection and fixation.

[0025] like Figure 3 As shown, the latch 14 is L-shaped, which is convenient for manual operation.

[0026] Specifically, when the cable of the present invention needs to be disassembled, the person only needs to pull the latch 14 away from the lower sleeve 15, and then the two connector parts can be slid out of the cable body, and then the outer sheath structure can be disassembled in a manner of removing the screws.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
