Cable used for elevator

Abstract

The invention relates to a cable and especially relates to a cable used for an elevator. The cable comprises a plurality of conductors and a plurality of insulators covering the conductors respectively. A female adhesive tape with a clamping groove and a male adhesive tape with a projection part are respectively arranged on two sides of each insulator, and the insulators can be detachably connected through the female and male adhesive tapes. After the insulators are mutually connected, the projection part of the male adhesive tape of any insulator is totally inserted into the clamping groove in the female adhesive tape on the adjacent insulator. Compared with the prior art, the detachable connection of two insulators are directly realized by interaction between the female and male adhesive tapes, and workers are enabled to increase the number of the conductors in the cable according to the practically increased number of devices in an elevator car in the future, so that the weight of the whole cable is effectively controlled, the production cost of the whole cable is effectively lowered, and the power consumed by the elevator car in the operation process is simultaneously lowered.

Description

technical field [0001] The invention relates to a cable, in particular to an elevator cable. Background technique [0002] The elevator cable, as a cable used to supply power and signal transmission to the elevator when the elevator car moves up and down, needs to have good reliability and stability. [0003] At present, the structure of the elevator cable is generally composed of several conductors coated with an insulating layer and an insulator coated on the outer surface of each conductor. And with the development of elevator electrical control technology, elevators have more and more functions, such as advertisement display in the car, floor display, etc., but at the same time, in order not to damage the original circuit design of the elevator, these devices are generally added in the later stage. In the car, in order to realize the control of different devices in the elevator, it is necessary to add different cores to the cable to complete the connection with the main...

AI Technical Summary

Problems solved by technology

[0004] However, it has been proved by practice that due to the heavy weight of the cables used in the elevator, and at the beginning of the design, it is necessary to reserve a few sets of wire cores for the cables in case of emergency, which will not only increase the speed of the entire elevator car going up and down. The power consumption of the operation will increase the raw materials of the cable during production. Whether it is an increase in insulating materials or conductive materials, the production cost of the entire cable will be greatly increased.
