Wiring device for door and window based on polymer dispersed liquid crystal films

Abstract

The invention relates to a wiring device for a door and window based on polymer dispersed liquid crystal films, comprising a door body and a frame body which are provided with a polymer dispersed liquid crystal film respectively, wherein the door body and the frame body are rotatably arranged by virtue of hinges, a rotary lead protective mechanism is arranged between the door body and the frame body, the lead protective mechanism comprises a movable leaf, a static leaf and a hollow shaft, the hollow shaft is internally provided with a transition lead, an outgoing lead of the polymer dispersed liquid crystal film in the door body is electrically connected with one end of the transition lead, and the other end of the transition lead is electrically connected with an epitaxy lead in the frame body; and the movable leaf is connected with the door body, and the static leaf is connected with the frame body. By applying the device in the invention, damages on the lead as a door is frequently opened and closed can be reduced or avoided, the service life of the lead can be prolonged, and the safety is enhanced.

Description

technical field [0001] The invention relates to a wiring device based on a polymer dispersed liquid crystal film door and window, which includes a door body and a frame body with a polymer dispersed liquid crystal film, and a rotating wire protection mechanism is arranged between the door body and the frame body, which can reduce the Minimize or avoid the force on the wires when opening and closing the door, thereby protecting the wires of the polymer dispersed liquid crystal film device from being damaged. technical background [0002] U.S. Patent 4,671,618 and Korean Patent Application No.93-018129 (Registration No.73348) respectively disclose a method for preparing a phase-separated polymer-dispersed liquid crystal. This method can be used to make a PDLC (polymer dispersed liquid crystal, PDLC for short) film , PALC film, collectively referred to as polymer dispersed liquid crystal film. Polymer dispersed liquid crystal film is a new electro-optic film material with rema...

Problems solved by technology

This type of device works by electric drive, and the device is electrically connected to the controller through wires. When using this type of device to make and install glass doors and windows with polymer dispersed liquid crystal films, two wires need to be introduced into the In the door frame, the lead wire method will affect the force on the wire. If the lead wire method is improper, when the door of the polymer dispersed liquid crystal film device is opened and closed, the wire between the door and the frame will be subjected to torsional force, friction force, and tensile force. , extrusion force, shear force, etc., as the number of door openings increases, the wires are easily damaged, causing problems such as leakage, open circuit, and reduced life. Therefore, it is necessary to provide a wiring system based on polymer dispersed liquid crystal film doors and windows The device can not only lead the wires out, but also ensure that the wires will not be damaged during the process of frequently opening and closing the door
