Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically a highly flexible cable. Background Technology

[0002] With the continuous development of technology, the performance requirements for cables are becoming increasingly stringent. Traditional cables are frequently bent or subjected to external compression during use. Due to their low toughness and flexibility, when cables are compressed, the internal conductors are squeezed and move. After the compression ends, the cable cannot return to its original state, which affects its service life.

[0003] Therefore, how to improve the flexibility of cables has become an urgent problem to be solved. To this end, a highly flexible cable is designed. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a highly flexible cable, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a highly flexible cable, comprising a cable body, the cable body being composed of six sets of core wires, a support member, and an outer sheath. The core wires are provided with conductors, an insulation layer, and a protective layer from the inside out. The insulation layer contains conductors inside and a protective layer outside. The support member is located in the middle of the inner part of the outer sheath. The outer wall of the support member is provided with core wires that are connected to the inner wall of the outer sheath at equal intervals. The outer sheath contains a filling layer inside.

[0006] Preferably, the support includes a buffer core, a collar is sleeved on the outside of the buffer core, connecting ribs are provided at equal intervals on the outer wall of the collar, through holes are opened at equal intervals on the collar, the through holes are located between two adjacent connecting ribs, a stop strip is connected to one end of the connecting rib, and a rubber ring is sleeved on the outside of the stop strip.

[0007] Preferably, the buffer core has an internal hole, and one side of the through hole has a spring strip that contacts the outer wall of the two rubber rings.

[0008] Preferably, the outer wall of the insulating layer is provided with a reinforcing layer, which is woven from nylon threads.

[0009] Preferably, both the spring bar and the outer sheath are made of silicone rubber.

[0010] Preferably, the buffer core, collar, connecting rib, stop strip, and rubber ring are all made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention effectively protects the conductor by incorporating a core wire, insulation layer, protective layer, and reinforcing layer. Combined with the support components and outer sheath, it provides stable support for the six core wires, preventing displacement of the core wires under external bending and compression. This improves the stable installation of the core wires within the outer sheath. Furthermore, this design gives the cable body high resilience, ensuring it retains its elasticity even after repeated bending, effectively enhancing its compressive strength, toughness, and flexibility.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example 1, by Figures 1-3The present invention includes a cable body, which is composed of six sets of core wires 1, a support member 14, and an outer sheath 13. The core wires 1 are provided with conductors 15, an insulation layer 2, and a protective layer 3 from the inside to the outside. The insulation layer 2 is provided with conductors 15 inside and the insulation layer 2 is provided with a protective layer 3 outside. The outer wall of the insulation layer 2 is provided with a reinforcing layer 4, which is made of nylon thread. Through the design of the reinforcing layer 4, the conductors 15 can be wrapped and protected, effectively extending the service life of the conductors 15. The support member 14 is provided in the middle of the inner part of the outer sheath 13. The outer wall of the support member 14 is provided with core wires 1 connected to the inner wall of the outer sheath 13 at equal intervals. The outer sheath 13 is provided with a filling layer 16 inside.

[0021] The support member 14 includes a buffer core 5, a collar 7 is sleeved on the outside of the buffer core 5, connecting ribs 9 are provided at equal intervals on the outer wall of the collar 7, and through holes 8 are provided at equal intervals on the collar 7. The through holes 8 are located between two adjacent connecting ribs 9. One end of the connecting rib 9 is connected to a stop strip 10, and a rubber ring 11 is sleeved on the outside of the stop strip 10.

[0022] The buffer core 5 has an inner hole 6 inside, and a spring strip 12 that contacts the outer wall of the two rubber rings 11 is provided on one side of the through hole 8.

[0023] Both the spring clip 12 and the outer sheath 13 are made of silicone rubber;

[0024] The buffer core 5, collar 7, connecting rib 9, stop strip 10 and rubber ring 11 are all made of rubber;

[0025] By positioning the elastic strip 12 between two adjacent rubber rings 11, the six sets of core wires 1 are stably installed between the two adjacent rubber rings 11, thereby limiting the position of the six sets of core wires 1 and preventing the core wires 1 inside the outer sheath 13 from shifting under external pressure, thus improving the installation stability of the core wires 1. Due to the rubber material of the support member 14 and the function of the inner hole 6 and through hole 8, it has more elasticity and recovery force, so that the cable body will not lose its elasticity after multiple bends, effectively improving the compressive strength of the cable body, and thus improving its toughness and flexibility.
