Contact type power supply structure of optical filter switcher

Abstract

The invention provides a contact type power supply structure of an optical filter switcher. The contact type power supply structure comprises a switching base, a lens base, an electromagnetic driving assembly and a U-shaped conductive part; the electromagnetic driving assembly is mounted on the lens base and is used for driving two optical filters mounted on the switching base to be switched to a position corresponding to an opening in the lens base; the first end of the U-shaped conductive part is electrically connected with the electromagnetic driving assembly; a positioning groove matched with the U-shaped conductive part in shape is formed in the lens base; a part of the U-shaped conductive part is arranged in the positioning groove; and the first end of the U-shaped conductive part forms a contact type conductive terminal used for being in contact with a conductive terminal of an external connector. The contact type power supply structure can avoid the problems of inconvenient wire passing, poor contact of the joint between a wire and a coil or an external connecting part, and the like, and has the characteristics of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a contact power supply structure of an optical filter switcher. Background technique [0002] With the development of imaging equipment, in order to have clear imaging both during the day and night, it is necessary to have a dual filter switcher to filter different light during the day and night. During the daytime, due to the interference of infrared light and a summary light on the CCD, which interferes with color reproduction, the objects reflected by the camera on the monitor and the objects directly seen by the human eye will change, resulting in color distortion, such as the human eye sees green, through the camera Then it turns blue, and bright colors become grayish. [0003] The double filter is specially used to correct the color cast and out-of-focus problems of the CCD camera, so that the acquired image will not be out of focus or color cast, and the infra...

Problems solved by technology

[0008] However, in this technical solution, the elastic contact piece uses its own elasticity to contact the conductive copper foil on the circuit board, and there is still a small contact area, and the size of the contact area may change when it is vibrated, causing impedance changes. Affect the size of the current, resulting in the problem that the opening and closing are not in place
