Problems solved by technology
[0003] In one prior art, the circuit board and the connector are pressed against the DMD device through a pressing structure, and the elastic pressing part is fastened to the fixing base by screws, mainly relying on the elastic deformation of the elastic pressing part itself to generate elastic force On the circuit board, since the elastic pressing part is fastened to the fixed seat, the elastic deformation range of the elastic pressing part is limited, which limits the pressing force of the pressing structure
However, the reliable contact of each contact is required between the connector and the DMD device. The area of each contact itself is very small, so the contact area between the contacts is also very small. If the pressing force is insufficient, it is easy to cause The contact between the circuit board, the connector and the DMD is poor, which affects the reliability of the contact among the three

The invention relates to a DMD assembly and a projection light machine. The DMD assembly includes a fixed seat, an elastic pressing part, a circuit board, a connector and a DMD device. The elastic pressing part includes an arched elastic pressing part and The fixed parts that are connected to the elastic pressing part and arranged opposite to each other are provided with limiting slots, and the limiting slots on at least one fixing part extend along the deformation direction of the elastic pressing part; the elastic pressing part and the The circuit board is pressed; the fixed seat includes a body part and a limit boss, and the end of the limit boss away from the body part is provided with an anti-off structure, and the anti-off structure at least partially extends out of the outer edge of the limit boss; wherein, each limit The position slots and the position-limiting bosses are correspondingly plugged and fitted. The fixed part is located between the body part and the anti-off structure. There is a gap between them. The invention can increase the elastic pressing force and improve the connection reliability of circuit boards, connectors and DMD devices.
Description
technical field [0001] The invention relates to the technical field of DMD installation, in particular to a DMD assembly and electronic equipment. Background technique [0002] DMD (Digital Mirror Device) is the core device of digital light processing technology (DLP), which mainly realizes projected images by adjusting reflected light. The DMD device is electrically connected to the circuit board through a connector. The contact between DMD devices, connectors, and circuit boards will have a great impact on the projection effect. In order to achieve good contact between DMD devices and connectors, it is necessary to set elastic parts to press the circuit board and connectors on the DMD device. . [0003] In one prior art, the circuit board and the connector are pressed against the DMD device through a pressing structure, and the elastic pressing part is fastened to the fixing base by screws, mainly relying on the elastic deformation of the elastic pressing part itself to ...
