Abstract
The invention relates to a cable for an elevator encoder, which comprises a wire core for transmitting an encoding signal, wherein the outer side of the wire core is sleeved with a sheath for protecting the wire core, an anti-interference shielding layer and a metal flexible pipe; the outer side of the metal flexible pipe is coated with an insulating layer; the wire core is a 15-core twisted cable; the outer side of the wire core is coated with a non-metal insulating protective layer; the outer side of the non-metal insulating protective layer is a metal shielding layer; the wire core consistsof tinning metal wires; both ends of the cable are connected with a 3-row 15-pin plug and s and a 2-row 14-pin 90311/014 plug; the metal flexible pipe is a flexible threaded pipe; and both ends of the metal flexible pipe are connected with grounding conducting wires. The cable for the elevator encoder has high structural safety, and can effectively prevent a core wire of the encoder from being damaged by external force; in addition, the shielding layer and the metal flexible pipe have double-layer shielding function so as to prevent external signals from interfering and enable the core wire to transmit encoding signals normally, and signal transmission is highly effective and reliable.
Description
Technical field
The present invention relates to the cable technology field, relate in particular to a kind of cable that is used for elevator encoder signal transmission usefulness.
Background technology
Elevator is the requisite equipment of riding instead of walk in the skyscraper, want frequent moving up and down, for elevator provides the cable of working power also inevitably along with it moves up and down, and along with development of science and technology and people work the life needs, in elevator, also need communication and monitoring waits some activities, for this reason, must hang relevant holding wire on the elevator next door, with elevator lifting repeatedly, in the elevator high-speed motion, the windage of cable is big, makes the frequent tension of cable, influence useful life, and because various circuits are too complicated, and these circuits are relatively poor relatively because of its tensile property, after the elevating movement of longer regular ground, fracture might appear, damage the consequence of bringing outage stagnation of movement or other correlation functions to interrupt.Because elevator speed is fast more, and the cable windage is big more, in order to guarantee cable security work, elevator can only run in the relatively low velocity interval, influences operating efficiency in addition.
As the CN2586227Y of Chinese patent Granted publication, elevator cable comprises that the insulating barrier outside inner wire, the conductor, the outer conductor and the sheath of insulating barrier periphery constitute, and it is characterized in that, is provided with the conductor of reinforcement and at least one pair of flexible insulation body in the sheath.These innovation and creation have strengthened the signal transmission of elevator encoder to a certain extent, have prolonged useful life, but because encoder installation site difference on the elevator, disturbs very big, so the cable of the transmission signals of configuration need highly effective and safe.
Be issued on the operation elevator by the encoder cable after signal controlling is generally write by encoder in the present elevator, and then control elevator operation, but the existing encoder cable is generally on the structure of using cables such as trailing cable, carry out coding transmission, if trailing cable fault, then coding can't transmit, and causes the bigger fault of elevator.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cable for elevator encoder.This cable for elevator encoder is soft, and structural safety is not easy by drawing crack.
In order to address the above problem, technical scheme of the present invention is such:
A kind of cable for elevator encoder comprises the core that is used for the transfer encoding signal, it is characterized in that, the described core outside is with the sheath of protection core, jamproof screen and metal hose, and the outside of metal hose is enclosed with insulating barrier.
Described core is 15 core twisted cables, and the outside of core is enclosed with nonmetal insulating protective layer, and the outside is a metal screen layer again, is made up of the tin metal silk, and the two ends of cable are connected with three row's 15 pin plugs and two rows, 14 pins, 90311/014 plug.
Described metal hose is flexible screwed pipe, is connected with earth lead at the two ends of metal hose.
The diameter of described core is 2mm-8mm.
The diameter of described metal hose is 12mm-20mm.
The width of thread of described metal hose is 2mm-4mm, and pitch is 2mm-4mm.
Beneficial effect: cable for elevator encoder of the present invention, the safety of structure height, can prevent effectively that the encoder heart yearn is subjected to damage, and screen and metal hose have the double layer screen performance, can prevent the interference of extraneous signal, make heart yearn normal transmission code signal, the signal transmission is efficient, reliable.
