Problems solved by technology

However, external dust or other foreign matter will enter the interior of the projection device through the opening to contaminate its electronic components and optical components, and the light emitted by the light source inside the projection device will also leak through the above-mentioned opening to cause light leakage. This affects the normal operation and projection quality of the projection device

Abstract

Provided are a projection device and a circuit board module. The projection device comprises a casing, the circuit board module, a light source, a light valve and a camera lens, and the casing is provided with at least one opening hole. The circuit board module comprises a circuit board, a plate element, an elastic structure and at least one connector. The circuit board and the plate element are arranged in the casing. The elastic structure is clamped between the circuit board and the plate element. The circuit board, the plate element and the elastic structure separate the inside of the casing into a first space and a second space. The first space is separated from the second space through sealing of the elastic structure, and the first space is communicated with the outside through the opening hole. The connector is allocated on the circuit board to be located in the first space, and the connector is exposed out by the opening hole. The light source, the light valve and the lens are allocated in the second space. Light beams sent from the light source reach the lens through the light valve.

Description

【Technical field】 [0001] The present invention relates to an optical device and its circuit board module, and in particular to a projection device and its circuit board module. 【Background technique】 [0002] A projection device is a display device for producing large-scale images. The imaging principle of the projection device is to convert the illumination beam generated by the light source into an image beam through a light valve, and then project the image beam onto a screen or a wall through a lens to form an image. With the advancement of projection technology and the reduction of manufacturing costs, the use of projection devices has gradually expanded from commercial use to home use. [0003] Generally speaking, a connector is provided on the circuit board inside the projector, and the connector is connected to an external power source or receives signals from other peripheral devices. In order for the connector to be connected to an external power line or data tra...
