Description

Technical Field

[0001] The utility model relates to the field of cables, and particularly relates to a cold-proof and anti-break cable. Background Art

[0002] A cable is a device used to transmit electric energy or signals, usually composed of several or several groups of wires. The definition of a cable can be understood from multiple perspectives, including its basic composition, uses, and classifications. A cable is mainly composed of several or several groups of wires that are insulated from each other and are usually twisted around a center, and the whole is covered with a highly insulating coating. This structure enables the cable to effectively transmit electric energy or signals while protecting the internal wires from external influences. Cables are widely used in the fields of electricity, communication, and related transmission. They can be used to transmit electric energy, signals, and data to achieve the conversion of electromagnetic energy. The scope of use of cables is very wide, including but not limited to the fields of power systems, communication systems, buildings, railways, aviation, etc. Cables can be classified according to their uses, usage environments, and structural characteristics. For example, according to their uses, they can be divided into power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, etc. In addition, according to the different transmission media, cables can also be divided into bare wires, cross-linked cables, and communication optical cables, etc. To sum up, as an important wire product, cables play an indispensable role in modern society. Their diverse classifications and wide application fields make them one of the infrastructure of multiple industries such as electricity and communication. Among them, the "cold-resistant cable" disclosed in the application number "CN202322515906.4" is also an increasingly mature technology. "For this cold-resistant cable, through the setting of the waterproof layer and the cold-proof layer, during use, the acrylic resin material has good light and color retention, water and chemical resistance, fast drying, convenient construction, easy construction recoating and rework. The waterproof layer of the acrylic resin material is evenly coated on the surface of the cable, which can play a waterproof role for the cable, thereby increasing the service life of the cable. The polytetrafluoroethylene material has heat resistance", but during the use of this cable, there are still the following defects: Although the waterproof layer, the cold-proof layer, and the acrylic resin material can indeed play a cold-proof effect, the cold-proof performance achieved only through the above structure is not significant enough. Based on this, it is necessary to provide a cable in which multiple structures cooperate with each other to significantly improve the cold-proof performance. In addition, from the perspective of its own strength during use, this cable may be broken after long-term use, affecting its service life. Based on this, it is necessary to provide a cable that can significantly improve the anti-break effect and extend the service life. Summary of the Utility Model

[0003] An embodiment of the utility model provides a cold-proof and anti-break cable, aiming to solve the problem that the existing cables have insufficient cold-proof, freeze-resistant, and anti-break effects.

[0004] To achieve the above object, the present utility model provides an anti-freezing and anti-breaking cable, including a cable assembly;

[0005] Wherein, the cable assembly includes a corrugated pipe, an outer sheath is sleeved inside the corrugated pipe, an anti-fold tape is sleeved on the inner wall of the outer sheath, an inner sheath is installed on the inner wall of the anti-fold tape, a filling layer is filled inside the inner sheath, several reinforcing ribs are embedded inside the filling layer, several heat preservation pipes are inserted inside the filling layer, and a copper core is installed on the inner walls of the several heat preservation pipes.

[0006] As a preferred solution of the present utility model, several embedding holes are opened at one end of the filling layer, and the several heat preservation pipes are all inserted inside the embedding holes.

[0007] As a preferred solution of the present utility model, the corrugated pipe is made of rubber.

[0008] As a preferred solution of the present utility model, both the outer sheath and the heat preservation pipe are made of cross-linked polyethylene.

[0010] As a preferred solution of the present utility model, the filling layer is made of mineral mud and the inner sheath is made of sponge.

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

[0012] 1. When the cable is in use, the corrugated pipe made of rubber can initially play a heat preservation effect, and the double heat preservation effects of the outer sheath and the heat preservation pipe made of cross-linked polyethylene can further improve the heat preservation performance of the cable. Finally, the inner sheath made of sponge and the filling layer made of mineral mud can isolate the external low-temperature environment, significantly enhancing the cold resistance and frost resistance of the cable. Compared with the heat preservation structure in the prior art "a cold-resistant cable", the present utility model can make the cable have multiple cold-resistant, frost-resistant and heat preservation effects through the mutual cooperation of the above structures, thereby enhancing the practicability of the cable;

[0013] 2. When the cable is in use, the outer sheath has a certain strength, so as to initially protect the inner copper core. At the same time, the anti-fold tape made of stainless steel is spirally sleeved on the side surface of the inner sheath, so the rigidity and wear-resistant and bend-resistant performance of the cable can be significantly enhanced. Finally, the filling layer and the several reinforcing ribs made of steel wires embedded therein can further improve the anti-breaking effect of the cable. Compared with the cable in the prior art "a cold-resistant cable", the present utility model can significantly improve the rigidity and anti-bending effect of the cable through the mutual cooperation of the above structures, thereby extending the service life of the cable.
