Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, specifically to a highly flexible control cable. Background Technology
[0002] Cables are typically made of several or groups of conductors twisted together like a rope. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being energized internally and insulated externally. Control cables are a type of cable.
[0003] The utility model with announcement number CN219534139U discloses a highly flexible control cable, including a cable body, a protective component on the cable body, an auxiliary component on the cable body, the protective component including a metal fireproof layer, the metal fireproof layer being disposed on the cable body, the outer surface of the metal fireproof layer being covered with a waterproof wrapping layer, the outer surface of the waterproof wrapping layer being provided with a polyester isolation layer, and a flexible outer sheath being fixed to the outer surface of the polyester isolation layer;
[0004] The above technical solution, by using a stainless steel annular concentric corrugated structure to form the internal metal fireproof layer, can greatly improve the flexibility of the cable body. At the same time, the flexible outer sheath uses a TPU insulation material, which further improves the flexibility of the cable body. In addition, the conductor shielding layer can be used to shield electromagnetic signal interference, thereby improving the signal interference resistance of the cable body. However, the cable does not have tensile strength after long-term use, and it does not have compressive strength when buried in the ground. It is also not easy to reduce the impact of moisture and conductivity on the use of the cable. Utility Model Content
[0005] The purpose of this invention is to provide a highly flexible control cable to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A highly flexible control cable includes a rubber tube layer and a cable core disposed between the rubber tube layers. An installation hole is opened at the center of the top of the rubber tube layer, and the cable core is installed in the installation hole. Several heat dissipation holes are opened at the end of the rubber tube layer near the edge. A steel wire mesh layer, an insulation layer and a moisture-proof layer are sequentially sleeved on the outer wall of the rubber tube layer from the inside to the outside. A reinforcing tube is sleeved on the outside of the moisture-proof layer, and a wear-resistant sleeve is sleeved on the outer wall of the reinforcing tube.
[0008] Furthermore, several round holes are provided on the end of the rubber tube near the mounting hole, and aluminum wires are provided in each of the round holes. The aluminum wires are arranged in close contact with the cable core.
[0009] In this invention, the inner diameter of the circular hole is matched with the outer diameter of the aluminum wire, and the aluminum wire is tightly inserted into the circular hole. The aluminum wire and the cable core cooperate with each other, which helps to connect and cooperate with external electrical devices.
[0010] Specifically, the heat dissipation holes are distributed in a ring at equal intervals, and all the heat dissipation holes penetrate the gel tube layer.

The support strips are in the shape of an "8", and the two ends of the support strips are bonded and fixed to the inner wall of the hollow chamber. The support strips are distributed in a ring at equal intervals.
[0019] In this invention, the combination of multiple support bars increases the compressive toughness of the reinforcing tube, thereby achieving internal protection and reducing damage to the cable core and aluminum wire.
[0020] Furthermore, the inner diameter of the wear-resistant sleeve is adapted to the outer diameter of the reinforcing tube, and the inner wall of the wear-resistant sleeve is bonded and fixed to the outer wall of the reinforcing tube.
[0021] In this invention, the wear-resistant sleeve protects the outer side of the reinforcing tube, reducing friction and wear from contact with objects in the external environment, thereby extending the overall service life.
[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] 1. This utility model provides tight protection between the cable core and aluminum wire by setting up a rubber tube layer, while also protecting them from being separated.
