Carbon brush contact conductive device

Abstract

The invention discloses a carbon brush contact type conductive device comprising a carbon brush device box, a positioning installation block, and a conductor rail. The upper end of the conductor rail is fixed on a profile, and the lower end is connected with the carbon brush device box. The top end of the carbon brush device box is connected with the conductor rail through rollers, and the carbon brush device box slides along the conductor rail. A carbon brush made of graphite is arranged inside the carbon brush device box, and a lead at the lower end of the carbon brush is connected with an electric hollow shutter through a terminal. The positioning installation block is arranged at the lower end of the conductor rail, and is fixed to the side of a door-window sash material. Electric conduction is achieved using the carbon brush in the invention. The problem that a shutter conductive device is non-conductive in the prior art is solved. The non-conduction defect of a conductive device is solved from different angles. Moreover, the whole device has a longer service life.

Description

technical field [0001] The invention relates to the technical field of electric louvers, in particular to a device for conducting electricity and controlling electric louvers with a carbon brush contact. Background technique [0002] The insulating glass is driven by a built-in electric blind conductive device. The conductive device has been used since the beginning of the blind, and has gradually developed into a built-in electric blind for sliding windows (doors). The commonly used conduction method is to conduct power supply through conductive contact between the conductive rail of the window (frame) material and the sliding conductive device on the window (fan). The common methods are copper conductive wheels and copper contact blocks. However, this kind of conductive device often appears non-conductive, and its non-conductive reasons are various, and the common ones are: the oxidation of the conductive copper sheet and the conductive wheel; the conductive wheel is easy ...

Problems solved by technology

However, this kind of conductive device often appears non-conductive, and its non-conductive reasons are various, and the common ones are: the oxidation of the conductive copper sheet and the conductive wheel; the conductive wheel is easy to deviate from the track of the conductive rail; the device of the conductive wheel is installed on the fan material On the other hand, the conductive copper sheet device is installed on the frame material, which causes the gap between the fan and the frame material to be misaligned with the conductive track; in addition, the drop angle after the door and window is installed for a period of time also accelerates the instability of the conduction
