Description

Technical Field

[0001] The invention relates to the technical field of elevator air-conditioning connecting wires, in particular to a tensile-resistant elevator air-conditioning flat connecting wire. Background Art

[0002] Elevator air conditioner is installed on the car and draws air from the elevator shaft. It is suitable for various passenger elevators, medical elevators, and sightseeing elevators. It is mainly used to improve the riding comfort of the elevator and solve the problem of the elevator car temperature being too high in the hot summer or the elevator car temperature being too low in the northern winter.

[0003] The flat connecting wire of the elevator air conditioner refers to the accompanying flat cable of the elevator air conditioner. This cable is usually designed to be flat to adapt to the space limitations inside the elevator car and ensure the flexibility and reliability of the cable. The flat connecting wire can be easily installed in the limited space of the elevator car while providing stable power transmission to ensure the normal operation of the elevator air conditioner.

[0004] A Chinese patent discloses an oil-filled grease elevator air-conditioning flat connecting wire (authorization announcement number CN219457184U). This patented technology greatly improves the product quality, and provides an oil layer between the cable core and the outer sheath layer, which not only prevents the surface of the cable core from sticking to the outer sheath layer and is easy to peel during use, but also makes the subsequent elevator air-conditioning connecting wire easy to bend during operation, and the conductor inside the cable core is not easy to break, effectively avoiding the phenomenon of broken conductors igniting and burning, and extending the service life of the elevator air-conditioning flat connecting cable core conductor; moreover, by providing an anti-puncture layer, the anti-puncture layer is formed by the fusion and extrusion of silicone particles and rubber, and has strong anti-puncture performance and effect, thereby being able to ensure the quality of the connecting wire.

[0005] However, the existing air-conditioning flat connecting wires are generally protected by a sheath to protect the wire core, which is actually subjected to a certain tension. When the external tension is too large, it is easy to cause the connecting wire to break and cause damage, which in turn affects the use of the air-conditioning flat connecting wire. In addition, the current connecting wires have poor fire resistance and are easily damaged by external high temperatures during use. Therefore, those skilled in the art provide a tensile elevator air-conditioning flat connecting wire to solve the problems raised in the above background technology. Summary of the invention
