Description

Technical Field

[0001] This application belongs to the field of cable technology, specifically a fire-resistant and pressure-resistant wire and cable. Background Technology

[0002] Cables are typically made up of several strands or groups of conductors (at least two conductors per group). Depending on the application, cables have different performance focuses. Their performance is mainly divided into mechanical properties and thermal properties. Good mechanical and thermal properties can greatly improve the versatility of cables. Mechanical properties mainly refer to tensile strength, elongation, bending properties, elasticity, and flexibility. Tensile properties (tensile strength and elongation) are generally achieved through the design of its steel strands and armor layers.

[0003] For example, application CN221687269U discloses a fire-resistant and pressure-resistant cable, belonging to the field of cable technology. This fire-resistant and pressure-resistant cable includes a cable body, which includes a cable core and a filling outer sheath. The filling outer sheath is sleeved on the outside of the cable core. A protective mechanism is provided between the protective component and the filling outer sheath, and the fire-resistant and pressure-resistant component is elastically sleeved on the outside of the filling outer sheath. The protective component is used to prevent sharp objects from penetrating, and the fire-resistant and pressure-resistant component is used to disperse external pressure to reduce local damage to the cable core. By dispersing the force multiple times, the force is dispersed when it reaches the cable core, thereby reducing damage to the cable core and the filling outer sheath. This reduces damage to the cable core caused by external squeezing, trampling, etc., and improves the service life of the cable core.

[0004] However, the cable in this application lacks safety design at the connection point, which makes it prone to breakage after prolonged use, affecting the overall safety and reliability during use. Utility Model Content

A screw handle is fixedly installed on the outer end of the fastening screw.

[0009] By adopting the above technical solution, the safety connecting sleeve can be securely installed, preventing it from easily falling off and increasing its stability during use.

[0010] In a preferred embodiment, the pressure-resistant and flame-retardant sheath includes an outer flame-retardant sheath, a puncture-resistant layer, an inner flame-retardant layer, a pressure-resistant strip, and an inner flame-retardant sheath.

[0011] In a preferred embodiment, the outer flame-retardant sleeve is a cross-linked polyethylene flame-retardant layer; the inner flame-retardant sleeve is a cross-linked polyethylene flame-retardant layer.

[0018] By adopting the above technical solutions, halogen-free flame-retardant TPE material has UV resistance, aging resistance, acid and alkali resistance, fatigue resistance, light weight, easy processing, good fluidity, and easy coloring. It is suitable for extrusion molding, which makes the cable body have better compressive strength during use and effectively protects the internal core of the cable body.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0020] In this application, during the connection of the cable body, after the cable body is connected, the safety connecting sleeve is placed over the pressure-resistant and flame-retardant sheath. Then, the safety connecting sleeve is moved and adjusted so that the transparent observation window faces the connection point of the cable body. Then, the fastening screw is tightened to fix the safety connecting sleeve. At this time, the connecting anti-breakage rod inside the safety connecting sleeve can protect and fix the connection point of the cable body, so that the connection point of the cable body will not be easily bent, increasing the firmness and reliability of the connection point of the cable body. At the same time, the transparent observation window also makes it easy to observe the connection point of the cable body, increasing the convenience of use. Attached Figure Description
