Description

Camera Module

The present invention relates to a camera module.

Recently, ultra-small camera modules have been developed and are widely used in small electronic products such as smartphones, laptops, and game consoles.

As automobiles become more popular, ultra-small cameras are widely used in vehicles as well as in small electronic products. For example, black box cameras for vehicle protection or objective data on traffic accidents, rear surveillance cameras that allow drivers to monitor the blind spots at the rear of the vehicle through a screen to ensure safety when reversing, and surrounding detection cameras that can monitor the surroundings of the vehicle are provided.

The camera may be equipped with a lens, a lens holder that accommodates the lens, an image sensor that converts an image of a subject captured by the lens into an electric signal, a printed circuit board on which the image sensor is mounted, and a cover can coupled to the printed circuit board. At this time, the printed circuit board may include a plurality of printed circuit boards that are spaced apart from each other.

In general, screw joints are used to join multiple printed circuit boards that are spaced apart from each other. In this case, since screw holes must be formed on each printed circuit board, the component mounting area of the printed circuit board may be limited.

In addition, multiple printed circuit boards spaced apart from each other need to be spaced apart at a certain distance to prevent interference between heat dissipation and mounting devices. In this case, there is the inconvenience of having to install a separate spacer to maintain a certain distance between multiple printed circuit boards spaced apart from each other.

The problem to be solved by the present invention is to provide a camera module capable of simultaneously fixing and supporting a plurality of printed circuit boards in a spaced state without separate spacers and screws, while improving EMI (Electro Magnetic Interference) performance.

Through this, the tolerance of the product can be compensated. The second coupling portion (510) can include a plurality of second coupling portions (5102, 5104, 5106). The plurality of second coupling portions (5102, 5104, 5106) can be formed on the first to third side surfaces of the shield, respectively.

The shield (500) may include an elastic member (520). At least a portion of the elastic member (520) may be bent to have elasticity. The elastic member (520) may be formed by being cut and bent at an upper end of a side surface of the shield (500). The elastic member (520) may be formed in a fourth groove that is concavely formed downward from an upper end of a body of the shield (500). The elastic member (520) may be formed in a central region of the fourth groove. The elastic member (520) may be formed to extend from the fourth groove. The elastic member (520) may include an inclined surface. The inclined surface of the elastic member (520) may be formed to extend from the fourth groove. The elastic member (520) may be disposed in an area adjacent to the second connecting portion (510) among the upper ends of the side surface of the shield (500). That is, since the elastic member (520) is arranged in an area other than the second groove (514) of the second coupling portion (510), the height of the second groove (514) of the second coupling portion (510) can be reduced, and thus the height of the shield (500) can be reduced. Through this, the size of the camera module (10) can be reduced. The elastic member (520) can be formed spaced apart from the second coupling portion (510). A spaced space can be formed between the side end of the elastic member (520) and the side surface of the shield (500). The ratio of the length of the spaced space formed between the side end of the elastic member (520) and the side surface of the shield (500) to the width of the elastic member (520) can be 1:1. For example, the sum (a) of the total lengths of the spaced space formed between the side surfaces of the shield (500) can be twice the length (b) of the width of the elastic member (520). At this time, the elastic member (520) can be placed in the middle of the space formed between the sides of the shield (500). Through this, the process for cutting and bending the elastic member (520) can be facilitated while maintaining the elasticity of the elastic member (520).

The elastic member (520) enables the second substrate (300) to be fixed to the shield (500). The elastic member (520) can press the second substrate (300) to bring the first coupling portion (310) and the second coupling portion (510) into close contact with each other. Specifically, the elastic member (520) comes into contact with the lower surface of the second substrate (300) and presses the lower surface of the second substrate (300) from below to above. In this case, the first protrusion (314) of the first coupling portion (310) of the second substrate (300) can be placed in close contact with each other below the second groove (514) of the second coupling portion (510) of the shield (500).

The elastic member (520) can be in contact with the lower surface of the second substrate (300) and press the lower surface of the second substrate (300) upward. The elastic member (520) can be in contact with the first ground portion formed on the lower surface of the second substrate (300). The elastic member (520) can be in surface-contact with the lower surface of the second substrate (300). Through this, the elastic member (520) can perform the role of a ground member that electrically connects the first substrate (200), the second substrate (300), and the shield (500).
